Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The conventional display device is configured with an SOC and a TCON chip, when the refresh mode is switched, the SOC generally sends a switching instruction to the TCON chip to complete the mode switching, and the specific switching modes mainly include two modes, one of which is that the SOC switches the mode of the TCON chip through a certain Input/Output Interface (IO), for example, a standard 51 pin Interface where the SOC of the motherboard is connected with the TCON chip, and one of which, for example, the 21 st pin is an hsr_mode pin, and when the pin status is high, the SOC controls the TCON to switch the HSR mode. When HSR_mode pin is in low state, it indicates that HSR mode is not switched, another switching control mode is to control through Inter-integrated circuit bus (Inter-INTEGRATED CIRCUIT, I2C) command, namely, SOC sends corresponding I2C switching command to TCON to control TCON to switch correspondingly.
Therefore, in the conventional mode switching process, two control chips of the SOC and the TCON are required to be completed together, and along with the continuous development of the display device, the control circuit board of the display device is developed towards the direction of smaller area and lower cost, and if each display device is configured with the TCON chip, the material cost of the display device can be increased, the design complexity of the circuit board can be increased for the refined circuit design, namely the design cost can be increased, and the refresh rate switching control can be completed only by configuring the TCON chip in the existing display device, so that the problem of high cost exists.
In order to solve the problem that the existing display equipment needs to be configured with a TCON chip to finish mode switching control, the application provides a control method, a device, electronic equipment and a storage medium of the display equipment, wherein the control state information of the display equipment is detected to determine mode switching instruction information according to the control state information, a target scanning signal and a target pixel signal are generated based on the mode switching instruction information, and then the display mode is switched by adopting the target scanning signal and the target pixel signal to obtain a display mode switching result corresponding to the display equipment; therefore, the mode switching of the display equipment can be completed without configuring a TCON chip, the problem that the existing display equipment can complete the mode switching control only by configuring the TCON chip is solved, and the cost can be effectively reduced.
Fig. 1 is a schematic flow chart of a child lock control method of a clothes airing machine according to an embodiment of the present application. The method can be applied to one or more electronic devices such as a television, a client, a server and the like. The main execution body of the method may be hardware or software. When the execution body is hardware, the execution body may be one or more of the electronic devices. For example, a single electronic device may perform the method, or multiple electronic devices may cooperate with one another to perform the method. When the execution subject is software, the method may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module. The present application is not particularly limited herein.
As shown in fig. 1, the present application discloses an embodiment, which provides a display device control method, and specifically includes the following steps:
Step S110, detecting control state information of the display device.
The display device may represent devices with different refresh rate switching functions, such as a television, a display screen, and the like, and the control state information may represent state information of an SOC chip in the display device, specifically may be state information of a control pin of the SOC chip in the display device, and specifically, when the SOC chip receives a refresh rate switching instruction, the state of the control pin may change, that is, whether the display device receives the refresh rate switching instruction may be determined by the control state information.
Step S120, determining mode switching instruction information according to the control state information.
Specifically, after the control state information is obtained, the mode switching instruction information can be determined according to the control state information, wherein the mode switching instruction information represents the switching instruction information corresponding to the current control state information, and because the control state information can represent the state information of the SOC chip in the display device, and different states of the SOC chip can represent that the SOC chip receives different instructions, the mode switching instruction information which is matched with the instruction received by the SOC chip can be determined according to the control state information.
In an example, when the display device receives the switching instruction a, the switching instruction a indicates switching to the refresh rate a, and the control state information of the display device is converted into the control state information a, so that the mode switching instruction information a adapted to the SOC chip receiving the switching instruction a can be determined according to the control state information a, and at this time, the mode switching instruction information a indicates the mode switching instruction information switching to the refresh rate a, and further, the subsequent step can be executed to switch the refresh rate of the display device to the refresh rate a. Of course, the foregoing is merely illustrative, and the embodiments may be modified according to the situations and requirements, and the embodiments are not limited thereto.
Step S130, generating a target scanning signal and a target pixel signal based on the mode switching instruction information.
Specifically, after the mode switching instruction information is determined, a target scan signal and a target pixel signal may be generated based on the mode switching instruction information, where the target scan signal may represent a signal for controlling the display device to execute a pixel, and the target pixel signal may represent a signal for controlling the display device to display a pixel, where it is to be noted that, since the mode switching instruction information may represent switching instruction information corresponding to the current control state information, that is, different control state information may determine different mode switching instruction information, and different mode switching instruction information may generate different target scan signals and different target pixel signals.
In an example, when the display device receives an instruction for switching to the refresh rate a, it detects that the control state information of the display device is the control state information a, determines that the mode switching instruction information corresponding to the control state information a is the mode switching instruction information a, where the mode switching instruction information a indicates switching instruction information for switching the refresh rate of the display device to the refresh rate a, and may generate the target scan signal a and the target pixel signal a based on the mode switching instruction information a, where the target scan signal a and the target pixel signal a may control the display screen to switch to the refresh rate a, that is, execute the content of the subsequent step S140, where the refresh rate a may be a custom or preconfigured refresh rate, such as 120Hz refresh rate, 240Hz refresh rate, and the like. Of course, the foregoing is merely illustrative, and the embodiments may be modified according to the situations and requirements, and the embodiments are not limited thereto.
And step 140, switching the display modes by adopting the target scanning signals and the target pixel signals to obtain a display mode switching result corresponding to the display equipment.
Specifically, after determining the target scanning signal and the target pixel signal, the target scanning signal and the target pixel signal may be used to perform display mode switching to obtain a display mode switching result corresponding to the display device, where the display mode switching may indicate that the display device is switched to a display mode for performing pixel scanning according to the target scanning signal and performing pixel data output according to the target pixel signal, and the display mode switching result may indicate whether the display mode switching performed by the display device is successful, that is, the display mode switching result may be a display mode switching success result or a display mode switching failure result, the display mode switching success result indicates that the display device is successful, and the display mode switching failure result indicates that the display device is failed.
It should be noted that, steps S110 to S140 in this embodiment may be all executed by an SOC chip in the display device, so that the SOC chip in the display device may determine the mode switching instruction information according to the control state information by detecting the control state information of the display device, generate the target scan signal and the target pixel signal based on the mode switching instruction information, and then perform display mode switching by using the target scan signal and the target pixel signal to obtain a display mode switching result corresponding to the display device.
In an alternative embodiment of the present application, step S120 determines mode switching instruction information according to the control status information, and specifically includes the substeps of extracting a control pin signal parameter from the control status information, determining mode switching instruction information based on a refresh mode switching instruction corresponding to a preset pin signal parameter when the control pin signal parameter belongs to the preset pin signal parameter, and determining a mode maintaining instruction as mode switching instruction information when the control pin signal parameter does not belong to the preset pin signal parameter.
In this embodiment, after the control state information is obtained, the control pin signal parameter may be extracted from the control state information, where the control pin signal parameter may represent a signal parameter of a preset pin of the SOC chip in the display device, then it may be determined whether the control pin signal parameter is a preset pin signal parameter, where the preset hardware signal parameter may represent a signal parameter that is preconfigured to conform to the refresh mode switching, that is, where the control pin signal parameter belongs to the preset pin signal parameter, which indicates that the control pin signal parameter is a signal parameter that conforms to the preconfigured refresh mode switching at this time, and may determine, based on the preset pin signal parameter, a mode switching instruction corresponding to a preset refresh mode switching instruction, where the refresh mode switching instruction may be used to instruct the display device to perform the refresh rate switching, where the control pin signal parameter does not belong to the preset pin signal parameter, that the control pin signal parameter is a signal parameter that does not conform to the preconfigured refresh mode switching at this time, where the mode maintaining instruction may be determined as mode switching instruction information, where the mode maintaining instruction indicates that the refresh mode switching is performed, that the mode maintaining instruction may be used to instruct the display device to maintain the refresh rate at the present.
In an example, when the preset pin signal parameter is a high level parameter, the control pin signal parameter is extracted from the control state information, and at this time, whether the control pin signal parameter belongs to the preset pin signal parameter is judged, that is, whether the control pin signal parameter is a high level parameter is judged, when the control pin signal parameter belongs to the preset pin signal parameter, that is, the control pin signal parameter is a high level parameter, the mode switching instruction information can be determined based on a refresh mode switching instruction corresponding to the preset pin signal parameter, and when the control pin signal parameter does not belong to the preset pin signal parameter, that is, the control pin signal parameter is not a high level parameter, that is, the mode maintaining instruction can be determined as the mode switching instruction information, and in addition, a plurality of preset pin signal parameters can be preconfigured, and different preset pin signal parameters correspond to different refresh mode switching instructions, for example, the refresh mode switching instruction corresponding to the preset pin signal parameter a is used for indicating that the refresh rate of the display device is switched to 120Hz, and the mode switching instruction corresponding to the preset pin signal parameter B is used for indicating that the refresh rate of the display device is switched to 240 Hz. Of course, the foregoing is merely illustrative, and the embodiments may be modified according to the situations and requirements, and the embodiments are not limited thereto.
In an alternative embodiment of the present application, step S130 generates the target scan signal and the target pixel signal based on the mode switching instruction information, which specifically includes the substeps of determining whether the mode switching instruction information is a refresh mode switching instruction, acquiring refresh picture line number information and refresh pixel data corresponding to the refresh mode switching instruction if the mode switching instruction information is the refresh mode switching instruction, determining the refresh scan signal corresponding to the refresh picture line number information, determining the refresh scan signal as the target scan signal, and generating the target pixel signal using the refresh pixel data.
In this embodiment, after determining the mode switching instruction information, it may be determined whether the mode switching instruction information is a refresh mode switching instruction, where the mode switching instruction information is not a refresh mode switching instruction, which indicates that refresh mode switching is not required at this time, and that subsequent steps are not required to be performed, where the mode switching instruction information is a refresh mode switching instruction, which indicates that switching of a refresh mode is required at this time, and different refresh mode switching instructions may correspond to a command to instruct the display device to switch to a different refresh rate mode, so that refresh screen line number information and refresh pixel data corresponding to the refresh mode switching instruction may be obtained, where the refresh screen line number information indicates a screen line number of the refresh rate mode to which the refresh screen line number information corresponds to the refresh mode, and the refresh pixel data indicates a pixel data of the refresh rate mode to which the refresh mode switching instruction corresponds, then a refresh scan signal corresponding to the refresh screen line number information may be determined, and the refresh scan signal may be determined as a target scan signal, where the refresh scan signal indicates a signal representing a screen line number to be scanned, and the target pixel signal may be generated using the pixel data, and the target pixel signal may indicate a pixel signal for outputting a display.
In an example, as shown in fig. 2, two refresh rate modes are included, namely, normal mode (4K2K 60 HZ) and HSR mode (4K1K 120 HZ), where the two refresh rate modes have differences in the number of refresh screen lines, the number of refresh screen lines in normal mode (4K2K 60 HZ) is the number of v_total 1=v_active+v_blank=2160+90=2250 in the upper half of fig. 2, the number of refresh screen lines in HSR mode (4k 1K120 HZ) is the number of refresh screen lines in the lower half of fig. 2, v_total=v_active+v_blank=1080+45=1125, where v_total refers to the total number of display screen lines, that is, the number of refresh screen lines, which represents the number of vertical scan lines in a complete frame, v_total includes the number of lines v_active and additional v_blank of the actual display content, and the additional number of lines can be used for controlling the number of refresh lines, and the additional line numbers of the backlight signal; when the embodiment is implemented, firstly, it is determined whether the mode switching instruction information is a refresh mode switching instruction, then, if the mode switching instruction information is a refresh mode switching instruction, the refresh picture line number information and the refresh pixel data corresponding to the refresh mode switching instruction are obtained, at this time, if the refresh mode switching instruction is an HSR mode (4K 1K120 HZ) refresh rate mode indicating the display device to switch to, the refresh picture line number v_total corresponding to the HSR mode (4K 1K120 HZ) refresh rate mode may be determined as the refresh picture line number information, and a refresh scan signal corresponding to the refresh picture line number information may be used to scan a signal of v_total, specifically, may refresh a scan clock signal, and the refresh scanning signal is determined as the target scanning signal, and then the refresh pixel Data can be used to generate the target pixel signal, and since the pixel Data corresponding to the refresh rate modes are different, the refresh pixel Data corresponding to the refresh mode switching instruction can be used to generate the target pixel signal at this time, as shown in fig. 2, if the refresh mode switching instruction is the HSR mode (4K 1K120 HZ) refresh rate mode indicating the display device to switch to, the target pixel signal is generated according to the refresh pixel Data in the lower half of fig. 2, and if the refresh mode switching instruction is the normal mode (4K 2K60 HZ) refresh rate mode indicating the display device to switch to, the target pixel signal is generated according to the refresh pixel Data in the upper half of fig. 2. Of course, the foregoing is merely illustrative, and the embodiments may be modified according to the situations and requirements, and the embodiments are not limited thereto.
In an alternative embodiment of the present application, step S140 performs display mode switching using a target scan signal and a target pixel signal to obtain a display mode switching result corresponding to a display device, and specifically includes the substeps of obtaining driving voltage management information corresponding to the display device when the mode switching instruction information is a refresh mode switching instruction, determining a target driving voltage corresponding to the refresh mode switching instruction according to the driving voltage management information, determining whether the target driving voltage is matched with a real-time voltage of the display device, generating a voltage adjustment signal according to the target driving voltage when the target driving voltage is not matched with the real-time voltage of the display device, and performing display mode switching using the target scan signal, the target pixel signal and the voltage adjustment signal to obtain the display mode switching result corresponding to the display device.
In this embodiment, in the process of performing display mode switching, whether the mode switching instruction information is a refresh mode switching instruction may be determined, where in the case where the mode switching instruction information is a refresh mode switching instruction, the driving voltage management information corresponding to the display device may be obtained, where the driving voltage management information indicates management information of a corresponding driving power supply when the display device performs display at different refresh rates, so that, according to the driving voltage management information, a target driving voltage corresponding to the refresh mode switching instruction may be determined, where the target driving voltage indicates a driving voltage of a refresh mode corresponding to the refresh mode switching instruction, and it may be determined whether the target driving voltage matches a real-time voltage of the display device, where in a case where the target driving voltage does not match the real-time voltage of the display device, it is indicated that, in this case, the real-time voltage of the display device cannot meet the driving voltage of the refresh mode corresponding to the refresh mode switching instruction, and in this case, a voltage adjustment signal may be generated according to the target driving voltage, where the voltage adjustment signal may indicate an adjustment signal for adjusting the driving voltage of the display device, and further, where the target scanning signal, the target pixel signal and the voltage adjustment signal may be used to perform display mode switching, and the display device may also include a display mode switching result.
Specifically, the existing display devices include a Power management integrated circuit (Power MANAGEMENT IC, PMIC) for controlling, and the driving voltage may be kept unchanged or may need to be adjusted when different display devices perform different refresh rate display, as shown in fig. 3, where a display device needs a difference table of driving voltages in both Normal mode and HSR mode display modes. As can be seen from the figure, in the normal mode and the HSR mode, the voltage related to the panel, such as VGH/VGL, is constant, while most of the voltage related to the Source driver, such as AVDD/HAVDD/VCOM/Gamma, needs to be switched with the refresh rate display mode. That is, under the condition that the mode switching instruction information is a refresh mode switching instruction, driving voltage management information corresponding to the display device is obtained, the driving voltage management information can be information contained in a table of fig. 3, at this time, according to the driving voltage management information, a target driving voltage corresponding to the refresh mode switching instruction is determined, at the time when the refresh mode switching instruction is switched to an HSR mode refresh rate display mode, an AVDD voltage corresponding to the refresh mode switching instruction is determined to be 15V, that is, the target driving voltage is determined to be 15V, and a real-time voltage of the display device is acquired, at this time, the target driving voltage 15V is not matched with the real-time voltage 16V of the display device, a voltage adjustment signal can be generated according to the target driving voltage, and further, in the process of performing display mode switching by adopting a target scanning signal, a target pixel signal and a voltage adjustment signal, the AVDD voltage of the display device can be adjusted from 16V to 15V, so as to obtain a display mode switching result corresponding to the display device. It can be seen that, in this embodiment, different driving voltage management information may be corresponding to different display devices, and the same driving voltage management information may also include a plurality of target driving voltages corresponding to the refresh mode switching command, such as VGH/VGL/AVDD/HAVDD/VCOM/Gamma voltages in fig. 3, for each type of target driving voltage, the step of generating the voltage adjustment signal according to the target driving voltage when the target driving voltage does not match with the real-time voltage of the display device may be performed. Of course, the foregoing is merely illustrative, and the embodiments may be modified according to the situations and requirements, and the embodiments are not limited thereto.
In addition, when determining whether the target driving voltage matches the real-time voltage of the display device, the SOC may read back, through 12C, the register value a in the PMIC to compare with the to-be-written value B, where the register value a is the real-time voltage of the display device, the to-be-written value B indicates that the target driving voltage matches the real-time voltage of the display device when the register value a is equal to the to-be-written value B, and no voltage adjustment signal may be generated at this time, and when the register value a is not equal to the to-be-written value B, indicates that the target driving voltage does not match the real-time voltage of the display device, and at this time, the voltage adjustment signal may be generated according to the target driving voltage, and in the display mode switching result corresponding to the display device, the SOC may write the to-be-written value B into the PMIC through I2C.
In an alternative embodiment of the present application, step S140 uses a target scan signal and a target pixel signal to perform display mode switching to obtain a display mode switching result corresponding to the display device, and specifically includes the substeps of obtaining a display scan parameter and real-time pixel data of the display device, updating the display scan parameter based on the target scan signal to obtain a target scan parameter, updating the real-time pixel data using the target pixel signal to obtain target pixel data, and generating a display mode switching result according to the target scan parameter and the target pixel data.
