The present invention relates to the field of liquid crystal display technologies, and in particular, to a common electrode voltage compensation control circuit and method, an array substrate, and a display device. Background technique

As the level of technology continues to improve, LCD (English: Liquid Crystal Display; Chinese: LCD) is becoming more and more known as a display device. At the same time, due to its simple process, high brightness, fast response, low cost and moderate operating temperature, LCD has a very broad application prospect.

Generally, the liquid crystal display device utilizes the voltage difference between the common electrode and the pixel electrode to control the rotation of the driving liquid crystal molecules, so whether the voltage difference between the common electrode and the pixel electrode is accurate or not plays a role in the display effect of the liquid crystal display device. Important role (When the voltage difference between the common electrode and the pixel electrode is abnormal, the voltage difference driving the liquid crystal molecules is no longer accurate, which eventually causes a problem in the gray scale of the displayed image, which is also known as the color shift phenomenon. ). Wherein, the pixel electrode voltage is obtained from an alternating signal provided by the data line, and the common electrode voltage is supplied from the common electrode line. However, due to the voltage coupling between the data line and the common electrode line, it is difficult to maintain the stability of the common electrode voltage, which eventually leads to the occurrence of color shift.

As a prior art solution, as shown in FIG. 1, FIG. 1 provides a common electrode voltage compensation circuit including: a feedback line 101, a calculation unit 102, a compensation unit 103, and a compensation line 104. The feedback line 101 is connected to the common electrode line Com through the feedback point a for extracting the common electrode voltage. The calculation unit 102 is connected to the feedback line 101 for comparing the common electrode voltage drawn from the feedback line 101 with the standard common electrode voltage. Yes, thereby determining whether a deviation occurs in the common electrode voltage on the common electrode line Com; a compensation unit 103 for calculating according to the calculation unit 102 As a result, a compensation voltage is provided for compensating for a deviation of the common electrode voltage on the common electrode line Com; the compensation line 104 is connected to the common electrode line Com through the compensation point b and/or the compensation point c for introducing the compensation voltage The common electrode line Com, thereby compensating for the deviation of the common electrode voltage. It should be noted that the above description about the common electrode voltage compensation process is merely exemplary. In fact, the compensation unit may also include a compensation voltage coefficient when providing the compensation voltage, thereby further adjusting the control of the common electrode voltage compensation process.

However, in the process of implementing the above-mentioned common electrode voltage compensation, the inventors have found that at least the following problems exist in the prior art: When compensating for the common electrode voltage, the compensation circuit in the prior art uses the compensation line to directly direct the compensation voltage back to Common electrode line. That is, the compensation process neutralizes both the compensation voltage and the deviation of the common electrode voltage to complete the entire compensation process. However, the compensation circuit is usually provided with a large number of electrical components such as capacitors and inductors, which will inevitably result in untimely compensation when the voltage is neutralized, that is, when the compensation is required, the introduction of the compensation voltage is not timely; When compensation is required, a compensation voltage is introduced instead. Therefore, the uncertainty of the compensation effect of the prior art common electrode voltage compensation circuit is caused, and even the disadvantage of overcompensation of the common electrode voltage may occur.

In the following description, for purposes of illustration and description, reference reference However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the invention.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The embodiment of the present invention provides a common electrode voltage compensation control circuit. As shown in FIG. 2, the common electrode voltage compensation control circuit includes: a first capacitor C1, a compensation voltage access module 1, and a reset module 2. The first end of the first capacitor C1 (the point a' shown in FIG. 2) is connected to the common electrode line Com. The compensation voltage access module 1 has an input terminal connected to the output terminal of the common electrode voltage compensation circuit (it is required to be noted that _, as shown in FIG. 1 , the compensation line 104 in the common electrode voltage compensation circuit is used to output the compensation voltage. Therefore, 2, connected to the output terminal of the common electrode voltage compensation circuit is connected to the compensation line 104.), for receiving the compensation voltage provided by the common electrode voltage compensation circuit; the output end and the second end of the first capacitor C1 (b, point as shown) connected; its control terminal (not shown in FIG. 2) is used to introduce a compensation voltage into the second capacitor C1 when the common electrode voltage on the common electrode line Com is deviated. end. The reset module 2 has an input terminal (c' point shown in FIG. 2) connected to the common electrode line Com, and an output end connected to the second end of the first capacitor C1, and its control terminal (not shown in FIG. 2) is used. When the common electrode voltage on the common electrode line Com does not deviate, the common electrode voltage on the common electrode line is introduced to the second end of the first capacitor C1.

The common electrode voltage compensation control circuit provided by the embodiment of the present invention is explained in conjunction with the schematic diagram of the circuit structure described in FIG. The common electrode voltage compensation control circuit is divided into two working phases: 1. The control compensation phase; 2. The reset phase. Assuming that the common electrode voltage on the common electrode line Com is deviated, the prior art common electrode voltage compensation circuit provides a compensation voltage according to the comparison calculation (where the common electrode voltage compensation circuit works in the prior art, Reference is made to the related description of the background art and the corresponding circuit structure of Fig. 1, which will not be described in detail herein. Since the common electrode voltage on the common electrode line is deviated at this time, the compensation voltage access module 1 of FIG. 2 introduces the compensation voltage into the second end of the first capacitor C1 under the control of its control terminal. For the second end of the first capacitor C1, a transition of the voltage value is generated on the ::::: terminal of the first capacitor C1 due to the introduction of the compensation voltage. At the same time, according to the bootstrap effect of the capacitor, the first voltage of the first capacitor C1 also produces a jump of the same voltage value. In fact, the voltage value of the above transition is determined by the compensation voltage, which is provided in order to compensate for the deviation of the common electrode voltage of the common electrode line. Therefore, by using the bootstrap effect of the capacitor, the common electrode voltage compensation control circuit compensates for the deviation of the common electrode voltage by controlling the compensation voltage, thereby eliminating the deviation of the common electrode voltage. So far, the first working phase of the common electrode voltage compensation control circuit is completed.

After the completion of the first working phase, the problem of the common electrode voltage deviation on the common electrode line is solved. To avoid the continued introduction of a compensation voltage that affects the already common common electrode voltage, the common electrode voltage compensation control circuit continues for the second stage of operation. When the common electrode voltage on the common electrode line does not deviate, the reset module 2 introduces the common electrode voltage to the second end of the first capacitor C1 under the control of its control terminal. It should be noted that, as shown in FIG. 2, the reset module 2 introduces the common electrode voltage into the second end of the first capacitor C1, that is, the voltage value of the b' point is equal to the voltage value of the common electrode voltage at the point c'. And the voltage value of the common electrode voltage at the point c' is again equal to the voltage value of the common electrode voltage at the point a'. Therefore, in fact, it is equivalent to resetting the first capacitor C 1 . The reset first capacitor C 1 will no longer have a compensation effect on the common electrode voltage; at the same time, the compensation voltage access module 1 is disconnected, which ensures that the common electrode voltage is not affected by the compensation voltage. So far, the second stage of operation of the common electrode voltage compensation control circuit is completed.

Through the above analysis process, it can be found that the common electrode voltage compensation control circuit of the embodiment of the present invention actually completes a compensation control action after completing the first working phase and the second working phase. If the common electrode voltage remains stable at this time, the common electrode voltage compensation control circuit does not change; and when the common electrode voltage deviates again, the common electrode voltage compensation control circuit will actually perform the above compensation control action again. . It should be noted that whether the common electrode voltage on the common electrode line is deviated can be determined by the prior art common electrode voltage compensation circuit. The instruction is determined by the calculation unit 102 or the compensation unit 103 or other structural unit included in the prior art common electrode voltage compensation circuit, and those skilled in the art can perform corresponding settings according to actual needs, and do not do this. Narration.

In addition, it is particularly emphasized that the common electrode voltage compensation control circuit provided by the embodiment of the present invention utilizes the bootstrap effect of the capacitor to complete the compensation action of the common electrode voltage, so there is no voltage in the prior art. And the compensation is not timely when the compensation is not timely; In addition, the compensation voltage access module and the reset module can control the compensation time of the compensation voltage in real time, which ensures the accuracy of the common electrode voltage compensation.

To facilitate the understanding of the technical solution of the present invention by those skilled in the art, the common electrode voltage compensation control circuit provided by the present invention will be described in more detail below with reference to specific embodiments.

As shown in FIG. 3, FIG. 3 is a schematic structural diagram of a common electrode voltage compensation control circuit according to an embodiment of the present invention. It should be noted that, for convenience of explanation, the structure of the common electrode voltage compensation circuit in FIG. 3 is omitted, and the specific structure omitted may refer to the corresponding structure of FIG. Undoubtedly, the feedback line 101 is used to pull out the common electrode voltage on the common electrode line; the compensation line 104 is used to output the compensation voltage.

Specifically, the compensation voltage access module in the common electrode voltage compensation control circuit includes a first thin film transistor T1 whose source is connected to the output end of the common electrode voltage compensation circuit (ie, connected to the compensation line 104), and the drain and the A second end of a capacitor C1 is connected, and a gate thereof is connected to the first clock signal line CK. The first clock signal transmitted by the first clock signal line CK is used to control the first thin film transistor T1 to be turned on when the common electrode voltage of the common electrode line is deviated, and to introduce a compensation voltage into the second end of the first capacitor. It should be noted that the first clock signal may be generated by the common electrode voltage compensation circuit, for example: when the common electrode voltage compensation circuit detects a deviation of the common electrode voltage, the control generates a first clock signal of a high level.

Further, the reset module includes a second thin film transistor T2 whose source is connected to the common electrode line, whose drain is connected to the second end of the first capacitor, and whose gate is connected to the second clock signal line CKB. The second clock signal transmitted by the second clock signal CKB is used to control the second thin film transistor T2 to be turned on when the common electrode voltage is not deviated, and the common electrode voltage on the common electrode line is introduced into the second end of the first capacitor. . It should be noted that the second clock signal can also be generated by the common electrode voltage compensation circuit. For example, when the common electrode voltage compensation circuit detects that the common electrode voltage has not deviated, it controls to generate a second clock signal of a high level.

The common electrode voltage of 0V is set to the voltage value of the standard common electrode voltage. For example, at a certain moment, the common electrode voltage fluctuates due to the voltage coupling of the common electrode line and the data line, assuming that the common electrode is at this time. The voltage becomes +5V. The common electrode voltage compensation circuit detects that the common electrode voltage fluctuates through the feedback line 101, and provides a compensation voltage -5V by the compensation line 104; and the common electrode voltage compensation circuit generates the first condition according to the detected fluctuation of the common electrode voltage. - A clock signal (the common electrode voltage is biased). Correspondingly, the first clock signal controls the first thin film transistor T1 to be turned on, and the first thin film transistor T1 connects the compensation voltage -5V to the second end of the first capacitor C1. Due to the compensation voltage -5V access, a voltage jump of -5V occurs at the second end of the first capacitor C1. Due to the capacitor bootstrap effect, at the first end of the first capacitor C1, the common electrode voltage also occurs - a voltage value of 5V jumps, so the common electrode voltage is changed from +5V to a standard voltage value of 0V.

Further, when the common electrode voltage is not deviated, the common electrode voltage compensating circuit detects that the common electrode voltage does not deviate through the feedback line 101, and generates a second clock signal (the common electrode voltage is not biased). At this time, the second clock signal controls the second thin film transistor T2 to be turned on, and the second thin film transistor T2 connects the common electrode voltage to the second end of the first capacitor C1. At this time, for the first capacitor C1, the voltage value at both ends is the same, that is, the reset resets the first capacitor C1; and at the same time, since the first thin film transistor T1 is not turned on at this time, the first capacitor C1 is no longer guaranteed. The common electrode voltage has an effect.

It should be noted that the above description of the values of the common electrode voltages is for the purpose of facilitating the understanding of the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention. In addition, the deviation width of the common electrode voltage can also be set. When the common electrode voltage deviation exceeds the set value, the control compensates the common electrode voltage; and when the common electrode voltage deviation does not exceed the set value, the first capacitor is applied. Reset.

In addition, as shown in FIG. 4, FIG. 4 is another schematic structural diagram of a common electrode voltage compensation control circuit according to an embodiment of the present invention. After comparison, it can be found that the difference between FIG. 4 and FIG. 3 is that: in the second thin film transistor T2 included in the reset module in the common electrode voltage compensation control circuit shown in FIG. 4, the gate of the second thin film transistor T2 passes. The inverter 31 is connected to the first clock signal line CK, thereby saving the second clock signal CKB. It should be noted that, according to the foregoing description about the first clock signal and the second clock signal, it can be found that the first clock signal and the second clock signal are inverted (gp, and a high level is generated when the common electrode voltage is deviated. The first clock signal thereby turns on the first thin film transistor, and generates a high level second clock signal to turn on the second thin film transistor when the common electrode voltage is not biased. In the common electrode voltage compensation control circuit shown in FIG. 4, the phase of the clock signal input to the first thin film transistor T1 and the clock signal input to the second thin film transistor T2 are reversed by the inverter 31, and thus The common electrode voltage compensation control circuit shown is equivalent. For the working process, reference may be made to the corresponding embodiment in FIG. 3, and details are not described herein.

In addition, the structural schematic diagram of the common electrode voltage compensation control circuit of the embodiment of the present invention may also be as shown in FIG. The difference between FIG. 5 and FIG. 3 is as follows: In the common electrode voltage compensation control circuit shown in FIG. 5, the compensation voltage access module includes a first thin film transistor T1, and the gate of the first thin film transistor T1 passes through the inverter 32. The second clock signal line CKB is connected, thereby saving the first clock signal CK. The working process can also refer to the corresponding embodiment in FIG. 3, and details are not described herein.
