Referring to fig. 2, fig. 2 is a schematic structural diagram of a tft-type lcd according to an embodiment of the application.

For convenience of description of the specific structure of the tft-type lcd 200, the embodiment of the present application will be described with reference to the schematic structural diagram of the tft-type lcd 200 shown in fig. 2, but the components of the tft-type lcd 200 may be arranged according to practical needs, and the specific combination and application of the components of the tft-type lcd 200 are not specifically limited in the embodiment of the present application, so fig. 2 should not be construed as the only structure of the tft-type lcd 200.

With the development of visualization, the application of the liquid crystal display is also becoming wider due to low power consumption, small volume and low radiation, wherein a thin film transistor type liquid crystal display (Thin film transistor liquid CRYSTAL DISPLAY, often referred to as TFT-LCD) is also one type of liquid crystal display. Thin film transistor type liquid crystal display (TFT-LCD) panels are commonly used in televisions, flat panel displays and projectors by using TFT technology to improve image quality.

In the embodiment of the present application, the tft-type lcd 200 includes a polarizer 210, a color filter 220, a liquid crystal cell 230, a tft substrate 240, a circuit board 250, a light guide plate 260, and a backlight 270.

Optionally, in the tft-type lcd 200, a backlight 270 is disposed at the bottom for emitting light, and the light may display a corresponding image through other elements disposed in the tft-type lcd 200. In the thin film transistor type lcd 200, an upper and lower polarizer 210 are further provided, and the polarizer 210 (Polarizer) is an optical element capable of converting natural light into polarized light, and has a property of selectively absorbing light vibrations in different directions, so that the polarizer 210 has a specific direction, when light is irradiated onto the polarizer 210, light vibration components perpendicular to the direction are completely absorbed, and only light vibration components parallel to the direction are used, the specific direction is called a polarization direction of the polarizer 210, and thus when polarization directions of the upper and lower polarizers 210 in the thin film transistor type lcd 200 are perpendicular to each other, light of the lower polarizer 210 cannot pass through the upper polarizer 210. At this time, in order to allow light to be displayed on the screen through the polarizers 210, a liquid crystal cell 230 filled with liquid crystal molecules may be disposed between the two polarizers 210, and the electric field is used to control the rotation of the liquid crystal molecules, so as to change the traveling direction of the light, so that the light can pass through the upper polarizer 210.

Further, in order to control the rotation of the liquid crystal molecules by using the electric field, the tft substrate 240 is further provided in the tft-type lcd 200, and the tft in the tft substrate 240 can drive the rotation of the liquid crystal molecules in the lcd 230 by using the outputted gray voltage, so as to change the polarization of the light, and then determine the bright and dark states of the pixel by using the polarizer 210, so that different electric fields can form different colors. In addition, in order to make the light emitted from the backlight source finally display different colors, a color filter 220 (CF color film) may be disposed on the upper layer of the liquid crystal cell 230, where the color filter 220 has three color units of red, green and blue, and after the light passes through the color filter 220, the pixels can display different colors, and these pixels emitting red, blue and green colors form a video image on the panel. It will be appreciated that the various circuit elements and optical elements in the thin film transistor type liquid crystal display 200 require a circuit board 250 to drive them.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a thin film transistor according to an embodiment of the application.

As shown in fig. 3, for convenience in describing the specific structure of the thin film transistor 300, a schematic structural diagram of the thin film transistor is taken as an example in the embodiment of the present application, but each component in the thin film transistor may be set according to actual requirements, and the combination and application of specific components in the thin film transistor are not specifically limited in the embodiment of the present application, so fig. 3 should not be construed as the only structure of the thin film transistor.

In the embodiment of the present application, the thin film transistor includes a glass substrate 310, a gate electrode 320, a gate insulating layer 330, a semiconductor layer 340, a source electrode 350, a drain electrode 360, and an insulating protective layer 370.

Optionally, the glass substrate 310 in the thin film transistor 300 is used as a substrate in the thin film transistor 300 for providing other elements thereon, the gate electrode 320 (gate) is used to drive the thin film transistor 300 to be turned off and on, and the thin film transistor 300 can output a gray voltage to drive the liquid crystal molecules to achieve the effect of light transmission of the polarizer, in the thin film transistor 300, the gray voltage is conducted between the source electrode 350 and the drain electrode 360, and finally the gray voltage output by the drain electrode 360 drives the pixel. Between the gate electrode 320 and the source electrode 350 (drain electrode 360) there is a semiconductor layer 340, the semiconductor layer 340 is an amorphous silicon (a-Si) semiconductor layer 340, and the thin film transistor 300 obtains an on-current by utilizing the property of silicon atoms in the a-Si semiconductor to capture electrons, so as to be continuously turned on and off to rotate the driving liquid crystal molecules, and finally, the display principle is realized. It will be appreciated that the gate insulating layer 330 and the insulating protective layer 370 in the thin film transistor 300 are used to avoid the conductive metal layers from electromagnetically affecting each other, resulting in element failure.

In the process of displaying images of a thin film transistor type liquid crystal display screen, liquid crystal molecules in a liquid crystal box are required to be driven to rotate through a thin film transistor, so that light rays can not normally drive the liquid crystal molecules through a polaroid to display corresponding images, but due to the property of an A-Si semiconductor in the thin film transistor, when the A-Si semiconductor works, chemical bonds (Si-Si) between partial silicon atoms in the A-Si semiconductor are broken under the action of illumination, partial silicon atoms form a hanging state, at the moment, the capability of capturing electrons of the A-Si semiconductor is reduced, the number of carriers in the thin film transistor is reduced, the starting current of the thin film transistor is reduced, the thin film transistor cannot be normally started, the thin film transistor cannot normally drive the liquid crystal molecules, the light rays cannot pass through the polaroid to display the corresponding images, the display screen is finally abnormal, the display screen cannot be continuously used after the thin film transistor is aged and is disabled, and the service life of the display screen is indirectly shortened.

Therefore, the embodiment of the application provides a display screen control method to solve the technical problems.

Alternatively, as can be seen from the description of the above embodiment, when the display screen displays an image, the backlight source in the display screen emits light to transmit through the polarizing plate and the CF color film to display the image, and the liquid crystal molecules that deflect correspondingly to the refraction property of the backlight source are also necessarily illuminated, so that the thin film transistor in the thin film transistor substrate is illuminated when the thin film transistor drives the liquid crystal molecules to rotate, but after the thin film transistor is illuminated, the chemical bond between the silicon atoms in the a-Si semiconductor is broken, so that the capability of the semiconductor for capturing electrons is reduced, and the starting current of the thin film transistor is insufficient, and the driving voltage of the driving liquid crystal molecules output by the thin film transistor is also insufficient.

It can be understood that, in order to enable the thin film transistor to have enough driving voltage to drive the liquid crystal molecules to rotate normally, when the thin film transistor is insufficient in starting voltage due to illumination aging, a certain amount of compensation voltage can be compensated for the driving voltage for driving the thin film transistor to start, so that the driving voltage for driving the thin film transistor is increased, the thin film transistor is enabled to have enough voltage to realize starting and closing, and further the thin film transistor is enabled to have enough driving voltage to drive the liquid crystal molecules to rotate normally, and finally the display screen displays an accurate image.

Further, when the driving voltage of the thin film transistor is compensated, a specific compensation amount can be determined in various manners, and one feasible method is to set a preset output voltage threshold for the thin film transistor, and when the actual output voltage of the thin film transistor is lower than the preset output voltage threshold, the driving voltage of the thin film transistor is compensated, but the voltage compensation method with the fixed threshold is difficult to adapt to the driving voltage compensation for the thin film transistor in various different practical application scenes.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a thin film transistor substrate according to an embodiment of the application.

As shown in fig. 4, the display control method is applied to a tft-type lcd, in which the tfts are all disposed in a tft substrate 400, and the tft substrate in the display includes at least a first tft 410 and a second tft 420, the first tft is disposed in a non-illumination area 430 of the tft substrate, and the second tft is disposed in an illumination area 440 of the tft substrate.

In another preferred embodiment of the present application, a first thin film transistor 410 is disposed in a non-illuminated area 430 of the thin film transistor substrate 400 for reference, a second thin film transistor 420 is disposed in an illuminated area 440 of the thin film transistor substrate 400 for display, the a-Si semiconductor in the first thin film transistor 410 is not illuminated, and aging, failure, etc. caused by chemical bond breakage due to too long illumination time are avoided, which means that the output voltage of the first thin film transistor 410 is stable, and the first output voltage of the first thin film transistor 410 can be used as a reference to compare with the second output voltage of the second thin film transistor 420, so that the required driving voltage compensation value of the current second thin film transistor 420 can be determined more accurately, and the driving voltage of the second thin film transistor 420 can be compensated according to the driving voltage compensation value.

It should be noted that the number of the first thin film transistors 410 and the number of the second thin film transistors 420 in the thin film transistor substrate 400 in fig. 4 are only illustrative, and in practical applications, the number of the first thin film transistors 410 and the number of the second thin film transistors 420 in the thin film transistor substrate 400 may be set according to the application requirements of the display screen, which is not limited in the embodiments of the present application.

Alternatively, since the first thin film transistor 410 needs to be a standard reference thin film transistor, it needs to be disposed in the non-illuminated area 430, in order to ensure that the first thin film transistor 410 is not affected by light, a coating technique may be used to mask the first thin film transistor 410, where a paste polymer, a molten polymer or a polymer melt is coated on paper, cloth, or a plastic film to form a composite (film), which is commonly used in insulation, masking, or corrosion protection applications, and the area where the first thin film transistor 410 is disposed in the non-illuminated area 430 by using a coating technique, so that light leakage is prevented, and the first thin film transistor 410 is not blocked by a backlight. With continued reference to fig. 4, since the second thin film transistor 420 is used for display and the first thin film transistor 410 is used for reference, in order not to affect the display effect, the second thin film transistor 420 is concentrated at the center portion of the thin film transistor substrate 400, and the first thin film transistor 410 is distributed at the edge portion of the thin film transistor substrate 400.

Referring to fig. 5, fig. 5 is a flowchart of a display screen control method according to an embodiment of the application. The execution main body of the embodiment of the application can be electronic equipment, a processor in the electronic equipment, and a service or a system for executing the display screen control method. For convenience of description, a specific implementation procedure of the display screen control method will be described below by taking an example that the implementation subject is a processor in an electronic device.

As shown in fig. 5, according to the above-mentioned tft-type lcd, tft substrate, first tft, second tft and corresponding specific structures, the display control method may at least include:

s501, respectively acquiring a first output voltage of a first thin film transistor and a second output voltage of a second thin film transistor.

Alternatively, as can be seen from the description of the above embodiment, the first thin film transistor in the thin film transistor substrate is not illuminated, and the first thin film transistor is not aged or disabled due to illumination, so that the gray scale voltage output by the first thin film transistor can be used as the reference standard of the output voltage of the second thin film transistor, and the driving voltage compensation value required by the current second thin film transistor can be determined according to the first output voltage of the first thin film transistor and the second output voltage of the second thin film transistor. Based on this, it is necessary to first acquire the first output voltage of the first thin film transistor and the second output voltage of the second thin film transistor, respectively.

Optionally, when the first output voltage and the second output voltage are collected, a collection instruction may be sent to the corresponding voltage collection circuit, where the collection instruction is used to instruct the voltage collection circuit to collect the first output voltage and the second output voltage. The voltage acquisition rules can be various, for example, an acquisition circuit can be arranged to perform continuous uninterrupted acquisition operation on the thin film transistor, so that the instantaneity and the accuracy of the acquired voltage information are ensured; the output voltage can be acquired according to the set preset acquisition frequency, so that the power consumption of the acquisition circuit is saved, and the power consumption of the whole circuit is further saved. On the other hand, when first output voltage and second output voltage are acquired respectively, the same preset acquisition frequency can be set for acquiring two output voltages, two preset acquisition frequencies can be set respectively, the acquisition frequency of the first output voltage of the first thin film transistor which is stable can be set to be lower, the acquisition frequency of the second output voltage of the second thin film transistor which is illuminated can be set to be higher, and circuit power consumption is further reduced. The method for acquiring the first output voltage and the second output voltage is not particularly limited in the embodiment of the application.

S502, determining a driving voltage compensation value corresponding to the second thin film transistor according to the first output voltage and the second output voltage.

Optionally, the first output voltage is a voltage output by the first thin film transistor which is not illuminated, so that the first output voltage can be used as a standard reference voltage, the second output voltage is a voltage output by the second thin film transistor which is subject to illumination aging, after the second thin film transistor is aged, the conducting capability from the source electrode to the drain electrode is weakened, compared with the first thin film transistor, the loss of the gray scale voltage is larger, therefore, the gray scale voltage reaching the drain electrode in the second thin film transistor is lower than the gray scale voltage normally displayed by the first thin film transistor, that is, the second output voltage is lower than the first output voltage, and in order to enable the second thin film transistor to reach a normal output voltage value, the driving voltage compensation value required by the second thin film transistor can be determined according to the difference between the first output voltage and the second output voltage after the first output voltage and the second output voltage are acquired.

Alternatively, when determining the driving voltage compensation value of the second thin film transistor, there may be various determination rules, for example, the driving voltage compensation value corresponding to the second thin film transistor under the ratio may be determined according to the ratio between the first output voltage and the second output voltage when the ratio between the two output voltages reaches the preset ratio value; the voltage difference between the first output voltage and the second output voltage can also be calculated, and the driving voltage compensation value corresponding to the second thin film transistor can be determined according to the voltage difference. The embodiment of the application does not limit the rule for determining the driving voltage compensation value.

And S503, compensating the driving voltage of the second thin film transistor according to the driving voltage compensation value.

Optionally, after determining the compensation value of the driving voltage required by the second thin film transistor, the driving voltage of the second thin film transistor can be directly compensated according to the compensation value, and when the second thin film transistor is driven by the compensated driving voltage, the second thin film transistor which is aged by illumination can still output enough voltage for displaying a normal picture on the display screen, so that the service life of the thin film transistor in the display screen is prolonged, the service life of the display screen is indirectly prolonged, and the user experience is improved.

In an embodiment of the application, a display screen control method is provided, which is applied to a thin film transistor type liquid crystal display screen, wherein in a thin film transistor substrate in the display screen, a first thin film transistor is arranged in a non-illumination area, and a second thin film transistor is arranged in an illumination area. Firstly, respectively acquiring a first output voltage of a first thin film transistor and a second output voltage of a second thin film transistor; then determining a driving voltage compensation value corresponding to the second thin film transistor according to the first output voltage and the second output voltage; and finally, compensating the driving voltage of the second thin film transistor according to the driving voltage compensation value. Because the first thin film transistor is arranged in the non-illumination area, and the second thin film transistor is arranged in the illumination area, when the second thin film transistor is subjected to illumination and aged to cause that the output voltage of the second thin film transistor cannot enable the display screen to normally display pictures, the driving voltage compensation value can be calculated to compensate the driving voltage of the second thin film transistor according to the output voltage of the first thin film transistor which is not aged and the output voltage of the second thin film transistor which is aged, and then the output voltage of the thin film transistor is increased to reach the normal value, so that the thin film transistor can still normally work when the thin film transistor is aged due to illumination, the display screen can normally display images, and the service life of the thin film transistor and the service life of the display screen are prolonged.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for controlling a display screen according to another embodiment of the application.

As shown in fig. 6, the display screen control method at least may include:

s601, acquiring light receiving time of a second thin film transistor, and respectively acquiring a first output voltage of the first thin film transistor and a second output voltage of the second thin film transistor if the light receiving time is larger than a preset light receiving time threshold value.

Alternatively, as can be seen from the above embodiments, the tft may be degraded or even fail due to exposure to light, and the voltage normally used for driving the display may not be output, so that the display screen may not display a normal picture. At this time, the driving voltage compensation can be performed on the thin film transistor which receives the light, and the driving voltage of the thin film transistor is increased, so that the thin film transistor can be normally turned on or off by means of enough driving voltage under the aging condition, and the normal and accurate display effect of the display screen can be realized.

Optionally, when the ageing thin film transistor is subjected to driving voltage compensation, a required driving voltage compensation value of the ageing thin film transistor needs to be determined according to the ageing degree of the thin film transistor, based on the driving voltage compensation value, a first thin film transistor can be set at a position, which is not illuminated, in the thin film transistor substrate to serve as a reference thin film transistor, the illuminated thin film transistor used for displaying serves as a second thin film transistor, and the first output voltage of the first thin film transistor and the second output voltage of the second thin film transistor are collected, so that the driving voltage compensation value required by the second thin film transistor is determined.

Further, in the embodiment of the present application, the processor may directly execute the display screen control method, or the processor may execute the display screen control method based on the control unit, that is, the processor may interact with the control unit, so as to instruct the control unit to perform related operations, and for convenience of description, the following description will take an example in which the processor executes the display screen control method based on the control unit.

Referring to fig. 7, fig. 7 is a schematic diagram of a control unit of a thin film transistor substrate 700 according to an embodiment of the application. For convenience of description of the control units of the tft substrate 700, the control unit schematic diagram of the tft substrate 700 in fig. 7 is taken as an example in the embodiment of the present application, but each control unit in the tft substrate 700 may be set according to actual requirements, and the combination and application of specific control units in the tft substrate 700 are not specifically limited in the embodiment of the present application, so fig. 7 should not be construed as the only control unit structure of the tft substrate 700.

As shown in fig. 7, the control unit of the thin film transistor substrate 700 includes an acquisition unit 710, a comparison unit 720, a compensation unit 730, an adjustment unit 740, and a memory 750.

Optionally, referring to fig. 7, when the first output voltage and the second output voltage are collected, a collection instruction signal may be sent to the collection unit 710 to instruct the collection unit 710 to collect the first output voltage and the second output voltage, and after the collection unit 710 collects the first output voltage and the second output voltage, further analysis processing may be performed on the first output voltage and the second output voltage to determine a driving voltage compensation value corresponding to the second thin film transistor.

Specifically, referring to fig. 8, fig. 8 is a schematic circuit diagram of a thin film transistor substrate 800 according to an embodiment of the application. As shown in fig. 8, in a circuit diagram of the tft substrate 800, the LCK driving voltage signal 810, the first tft 820, the second tft 830, the LC resonant circuit 840, and the acquisition circuit 850 are included, wherein the LCK driving voltage signal 810 is electrically connected to the gate (G) of the second tft 830; the first thin film transistor 820 and the second thin film transistor 830 are electrically connected to one LC resonant circuit 840 respectively, the drain (D) of the first thin film transistor 820 is electrically connected to the acquisition circuit 850, and the drain (D) of the second thin film transistor 830 is electrically connected to the acquisition circuit 850.

The driving circuit outputs the driving voltages of the first thin film transistor 820 and the second thin film transistor 830, after the gray-scale voltage inside the first thin film transistor 820 is turned on from the corresponding source (S) to the drain (D) and the gray-scale voltage inside the second thin film transistor 830 is turned on from the corresponding source (S) to the drain (D), the collecting unit 710 collects the first output voltage of the drain (D) of the first thin film transistor 820 and the second output voltage of the drain (D) of the second thin film transistor 830 through the collecting circuit 850, so that the driving voltage compensation value required by the second thin film transistor 830 can be determined according to the first output voltage and the second output voltage.

Optionally, when the time of the liquid crystal display is shorter, that is, when the time of the second thin film transistor receiving light is shorter, the second thin film transistor may not be aged obviously, so that compensation for the driving voltage of the second thin film transistor is not needed, and voltage collection of the thin film transistor does not have important practical significance at this time, therefore, a preset light receiving time threshold value can be set, and when the light receiving time of the second thin film transistor is greater than the preset light receiving time threshold value, the voltage collection operation is performed on the first thin film transistor and the second thin film transistor, so that the pressure of collection and processing can be greatly reduced, and the power consumption of the display and the thin film transistor in the earlier use period can be greatly reduced.

It can be understood that when the preset light receiving time threshold is set, the relation between the light receiving time and the aging degree of the second thin film transistor can be measured by using a plurality of test tests and a data statistics analysis method, so as to determine the preset light receiving time threshold.

S602, if the first output voltage is determined to be greater than the second output voltage, a voltage difference between the first output voltage and the second output voltage is calculated.

Optionally, when the illuminated time of the second thin film transistor reaches the preset light receiving time threshold, compensation may be required for the driving voltage of the second thin film transistor, and then the driving voltage compensation value may be determined according to the difference between the first output voltage and the second output voltage acquired by the acquisition unit 710. It will be readily understood that the difference refers to the difference between the two output voltages in the case where the first output voltage is greater than the second output voltage, because when the first output voltage and the second output voltage are equal, it means that the second thin film transistor does not suffer from aging, that is, the driving voltage does not need to be compensated, and when the circuit fluctuates to cause the second output voltage to be greater than the first output voltage, the difference between the two voltages does not occur due to aging of the second thin film transistor, or cannot be used as a basis for determining the compensation value. Based on this, the driving voltage compensation value may be determined according to the two voltage differences after determining that the first output voltage is greater than the second output voltage.

Alternatively, referring to fig. 7, after the collecting unit 710 collects the voltages, the comparing unit 720 may compare the two voltages to ensure that the obtained voltage difference is a voltage difference obtained by that the first output voltage is greater than the second output voltage. As can be appreciated from the description of the above embodiments, there are various rules for determining the driving voltage compensation value, and in the embodiment of the present application, the driving voltage compensation value is determined based on the voltage difference between the first output voltage and the second output voltage, which is taken as an example, and explained in detail.

Alternatively, in the control unit of the thin film transistor substrate 700, the voltage difference between the first output voltage and the second output voltage may be calculated by the compensation unit 730, and the driving voltage compensation value for the second thin film transistor may be determined based on the voltage difference.

S603, determining a driving voltage compensation value corresponding to the second thin film transistor according to the voltage difference.

Optionally, after the voltage difference between the first output voltage and the second output voltage is calculated, the voltage difference may be smaller, so that the aging of the second thin film transistor does not affect the display result, and the driving voltage compensation of the second thin film transistor is not required, so that when the driving voltage compensation value is determined, a preset compensation threshold may be set, and when the voltage difference is greater than the preset compensation threshold, the current second thin film transistor is considered to need the driving voltage compensation, so that the power consumption of the compensation unit 730 and the power consumption of the subsequent related circuit units may be reduced.

Specifically, if the voltage difference is determined to be greater than the preset compensation threshold, determining a driving voltage compensation value corresponding to the second thin film transistor according to the voltage difference. In the embodiment of the present application, an empirical value of 0.5V is obtained through experiments as an example of the preset compensation threshold, and if the voltage difference is less than or equal to 0.5V, the preset compensation threshold may be regarded as normal aging of the second thin film transistor, and if the voltage difference is greater than or equal to 0.5V, the driving voltage is regarded as the driving voltage of the second thin film transistor.

Optionally, on the basis of setting a preset compensation threshold, a preset aging threshold may be further set, where the threshold is a representation that when the voltage difference reaches the preset aging threshold, it is indicated that the aging degree of the second thin film transistor has already achieved a certain degree of adverse effect on the display effect of the display screen, that is, the aging of the second thin film transistor reaches the threshold, and at this time, the output voltage, the voltage difference, the current usage information of the second thin film transistor and the like of the second thin film transistor may be recorded, so that a related technician may analyze and count the usage situation of the second thin film transistor, and be convenient for optimizing and adjusting the compensation scheme or other related schemes.

Optionally, when determining the corresponding driving voltage compensation value according to the voltage difference, a preset compensation rule may be preset, where the preset compensation rule includes a correspondence between the voltage difference and the driving voltage compensation value, and the compensation unit 730 may directly determine the driving voltage compensation value according to the preset compensation rule. The preset compensation rule may be a corresponding relationship between a voltage difference and a compensation value, which are determined in advance through a large amount of experimental data, or may be a compensation value obtained by calculating according to a voltage difference through a preset calculation process.

Further, a preset compensation rule is obtained, and a driving voltage compensation value corresponding to the voltage difference is determined according to the compensation rule. In the embodiment of the present application, taking the corresponding relationship between the voltage difference and the compensation value, which are determined in advance through a large amount of experimental data, as a preset compensation rule, the explanation of the subsequent scheme is performed. Firstly, the compensation unit 730 needs to obtain a preset compensation rule to determine the current driving voltage compensation value, and then the compensation unit 730 may directly receive the preset compensation rule from the server, or may obtain the preset compensation rule from the outside, or may obtain the preset compensation rule from the connected memory 750, referring to fig. 7, in the embodiment of the present application, after obtaining the preset compensation rule from the memory 750, the compensation unit 730 determines the driving voltage compensation value corresponding to the voltage difference according to the preset compensation rule, by taking the preset compensation rule obtained from the memory 750 as an example.

It should be noted that when the driving voltage compensation value is determined based on the voltage difference, the voltage difference may be a voltage difference that satisfies a preset compensation threshold value in the case where the preset compensation threshold value is set, or may be a voltage difference obtained in the case where the preset compensation threshold value is not set.

And S604, transmitting a driving voltage compensation value to a driving circuit corresponding to the second thin film transistor, wherein the driving voltage compensation value is used for indicating the driving circuit to compensate the driving voltage of the second thin film transistor according to the driving voltage compensation value.

Optionally, after determining the driving voltage compensation value corresponding to the second thin film transistor through the compensation unit 730, the compensation value needs to be sent to the adjustment unit 740, and the adjustment unit 740 can adjust the driving voltage output by the driving circuit corresponding to the second thin film transistor according to the compensation value, so that the driving circuit outputs the compensated driving voltage, and further, the second thin film transistor which is subjected to illumination and ageing can still output enough voltage for the display screen to display a normal picture, so that the service life of the thin film transistor in the display screen is prolonged, the service life of the display screen is also indirectly prolonged, and the user experience is improved.

Specifically, referring to fig. 7, the adjusting unit 740 has an integrated power management circuit (PMIC) that can generate a driving voltage signal (LCK) of the second thin film transistor, wherein the LCK signal is a clock square wave signal, which is connected to the gate of the second thin film transistor and is the driving voltage of the second thin film transistor, and the LCK signal can drive the second thin film transistor to be turned on and off.

Referring to fig. 9, fig. 9 is a schematic diagram illustrating compensation of a driving voltage signal according to an embodiment of the application. As shown in fig. 9, after the driving voltage compensation value is determined, the square wave amplitude of the LCK signal is increased according to the compensation value, and at this time, the on voltage of the second thin film transistor is increased, for example, when the voltage difference is 0.5V, the amplitude of the LCK signal needs to be increased by 1V, so as to increase the on current of the second thin film transistor, increase the number of carriers in the second thin film transistor, and ensure that the aged second thin film transistor can output normal gray scale voltage, so that the display screen displays a normal picture.

Referring to fig. 8, it is easy to understand that the driving circuit outputs the LCK driving voltage signal 810 to drive the first thin film transistor 820 and the second thin film transistor 830, and after the adjusting unit 740 receives the compensation value, the adjusting unit can adjust the amplitude of the LCK driving voltage signal 810 output by the driving circuit of the second thin film transistor 830 according to the compensation value, and drive the second thin film transistor 830 according to the compensated driving voltage signal 810, so that the second thin film transistor 830 can obtain enough driving voltage, and further obtain the on current for normal display of the display screen.

S605, collecting a third output voltage of the second thin film transistor, and correcting the driving voltage compensation value according to the third output voltage and the first output voltage.

Optionally, in order to further determine that the current display screen can display a normal picture, and determine whether the second thin film transistor outputs a gray scale voltage for normal display, after the driving voltage compensation of the second thin film transistor is completed, a third output voltage of the second thin film transistor may be collected, the third output voltage is compared with the first output voltage again for analysis, and the driving voltage compensation value is further adjusted and corrected according to the comparison analysis result. When the comparison analysis is performed, a preset adjustment condition can be set, the voltage difference is analyzed according to the condition, for example, when the third output voltage is smaller than the first output voltage and the voltage difference is larger than 0.5V, the compensation is considered to be required to be corrected, and when the third output voltage does not meet the condition, the voltage compensation is considered to be successful and the correction is not performed.

Optionally, after correcting the compensation value to be corrected, the output voltage of the second thin film transistor after the current correction and compensation can be collected again, and the comparison analysis is performed on the first output voltage, the corrected compensation value is further adjusted and corrected according to the comparison analysis result, and if the corrected compensation value does not meet the target compensation effect, the correction can be continued. The correction times can be set to a preset threshold, when the correction times reach the preset threshold, the correction is not performed, but operations such as collection and calculation are performed again. Thus, the correction effect can be further checked, and the final compensation is ensured to realize the target display effect.

In an embodiment of the application, a display screen control processing method is provided. On the basis of carrying out driving voltage compensation on the second thin film transistor according to the first output voltage and the second output voltage, the second thin film transistor to be compensated is limited in the aspects of presetting a light receiving time threshold value and the like, unnecessary power consumption of the display screen in the early use period is reduced, the corresponding driving voltage compensation value is determined through the voltage difference and a preset compensation rule, the integral power consumption of the display screen is reduced, the driving voltage is compensated by adjusting the amplitude of a driving voltage signal, and finally, the second thin film transistor which is subjected to light receiving and ageing can still output enough voltage for the display screen to display a normal picture, so that the service life of the thin film transistor in the display screen is prolonged, the service life of the display screen is indirectly prolonged, and the user experience is improved.
