[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] Traditional display devices are equipped with SOC and TCON chips. When switching the refresh mode, the SOC usually sends a switching instruction to the TCON chip to complete the mode switching. There are two specific switching methods. One is that the SOC switches the mode of the TCON chip through a certain input / output interface (IO), such as the standard 51-pin interface connecting the motherboard SOC and the TCON chip. One of the pins, such as the 21st pin, is HSR_modepin. When the pin state is high, it means that the SOC controls the TCON to switch to HSR mode. When the HSR_mode pin is in a low state, it means that the HSR mode switching is not performed; another switching control method is to control through the Inter-Integrated Circuit (I2C) instruction, that is, the SOC sends the corresponding I2C switching instruction to TCON to control TCON to switch accordingly.

[0056] It can be seen that the traditional mode switching process requires the joint efforts of two control chips, SOC and TCON. With the continuous development of display devices, the control circuit boards of display devices are also developing towards smaller area and lower cost. If each display device is equipped with a TCON chip, it will not only increase the material cost of the display device, but also increase the complexity of circuit board design for refined circuit design, which means that the design cost will also be increased. Existing display devices need to be equipped with TCON chips to complete the switching control of the refresh rate, which leads to high cost.

[0057] In order to solve the high cost problem that existing display devices need to be configured with a TCON chip to complete mode switching control, the present application provides a display device control method, device, electronic device and storage medium, which detects the control status information of the display device, determines the mode switching instruction information based on the control status information, and generates a target scanning signal and a target pixel signal based on the mode switching instruction information, and then uses the target scanning signal and the target pixel signal to switch the display mode to obtain the display mode switching result corresponding to the display device; thereby, the mode switching of the display device can be completed without configuring a TCON chip, which solves the high cost problem that existing display devices need to be configured with a TCON chip to complete mode switching control, and can effectively reduce costs.

This method can be applied to one or more electronic devices such as a television, a client, and a server. In addition, the execution subject of this method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the above-mentioned execution subject is software, this method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0059] like Figure 1 As shown, the present application discloses an embodiment, providing a display device control method, which may specifically include the following steps:

[0060] Step S110: Detecting control status information of the display device.

[0061] Among them, the display device can represent a device with different refresh rate switching functions, such as televisions, display screens and other devices, and the control status information can represent the status information of the SOC chip in the display device, specifically, it can be the status information of the SOC chip control pin in the display device. Specifically, when the SOC chip receives a refresh rate switching instruction, the state of the control pin will change, that is, it can be determined whether the display device has received the refresh rate switching instruction through the control status information.

[0062] Step S120: Determine mode switching instruction information according to the control state information.

[0063] Specifically, after obtaining the control state information, the mode switching instruction information can be determined based on the control state information, wherein the mode switching instruction information represents the switching instruction information corresponding to the current control state information. Since 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 has received different instructions, the mode switching instruction information that is compatible with the instruction received by the SOC chip can be determined based on the control state information.

[0064] In one example, when the display device receives a switching instruction A, the switching instruction A indicates switching to refresh rate A, and the control state information of the display device is converted into control state information A, so that the mode switching instruction information A that matches the switching instruction A received by the SOC chip can be determined according to the control state information A, and the mode switching instruction information A at this time indicates the mode switching instruction information of switching to refresh rate A; and then the subsequent steps can be executed to switch the refresh rate of the display device to refresh rate A. Of course, the above is only an example for illustration, and it can be adjusted according to the scene and requirements during the specific implementation, and this embodiment does not make specific limitations on this.

[0065] Step S130: Generate a target scanning signal and a target pixel signal based on the mode switching instruction information.

[0066] Specifically, after determining the mode switching instruction information, a target scanning signal and a target pixel signal can be generated based on the mode switching instruction information, wherein the target scanning signal can represent a signal for controlling the display device to execute pixels, and the target pixel signal can represent a signal for controlling the display device to display pixels; it should be noted that since the mode switching instruction information can represent the switching instruction information corresponding to the current control state information, that is, different control state information can determine different mode switching instruction information, and different mode switching instruction information can generate different target scanning signals and target pixel signals.

[0067] In one example, when the display device receives an instruction to switch to refresh rate A, the control state information of the display device is detected as control state information A, and the mode switching instruction information corresponding to the control state information A is confirmed to be mode switching instruction information A, and the mode switching instruction information A indicates the switching instruction information for switching the refresh rate of the display device to refresh rate A. At this time, based on the mode switching instruction information A, a target scanning signal A and a target pixel signal A can be generated, and the display screen can be controlled to switch to refresh rate A through the target scanning signal A and the target pixel signal A, that is, the content of the subsequent step S140 is executed; wherein the refresh rate A can be a custom or pre-configured refresh rate, such as a 120Hz refresh rate, a 240Hz refresh rate, etc. Of course, the above is only an example for illustration, and it can be adjusted according to the scene and needs during specific implementation, and this embodiment does not make specific limitations on this.

[0068] Step S140: using the target scanning signal and the target pixel signal to switch the display mode, and obtaining a display mode switching result corresponding to the display device.

[0069] Specifically, after determining the target scanning signal and the target pixel signal, the target scanning signal and the target pixel signal can be used to switch the display mode to obtain a display mode switching result corresponding to the display device, wherein the display mode switching can indicate switching the display device to a display mode that performs pixel scanning based on the target scanning signal and outputs pixel data based on the target pixel signal, and the display mode switching result can indicate whether the display mode switching of the display device is successful, that is, the display mode switching result can be a display mode switching success result or a display mode switching failure result, the display mode switching success result indicates the result of a successful display mode switching of the display device, and the display mode switching failure result indicates the result of a failed display mode switching of the display device.

[0070] It should be noted that steps S110-S140 in the present embodiment can all be executed by the SOC chip in the display device, so that the SOC chip in the display device can detect the control state information of the display device to determine the mode switching instruction information based on the control state information, and generate a target scan signal and a target pixel signal based on the mode switching instruction information, and then use the target scan signal and the target pixel signal to switch the display mode to obtain the display mode switching result corresponding to the display device; there is no need to configure the TCON chip, but the mode switching of the display device can be completed only based on the SOC chip, which solves the high cost problem that the existing display devices need to be configured with a TCON chip to complete the mode switching control, and can effectively reduce costs.

[0071] In an optional embodiment of the present application, step S120 determines the mode switching instruction information based on the control status information, and may specifically include the following sub-steps: extracting the control pin signal parameters from the control status information; when the control pin signal parameters belong to the preset pin signal parameters, determining the mode switching instruction information based on the preset refresh mode switching instruction corresponding to the preset pin signal parameters; when the control pin signal parameters do not belong to the preset pin signal parameters, determining the mode maintenance instruction as the mode switching instruction information.

[0072] In this embodiment, after obtaining the control state information, the control pin signal parameter can be extracted from the control state information. The control pin signal parameter can represent the signal parameter of the preset pin of the SOC chip in the display device. Then, it can be determined whether the control pin signal parameter is the preset pin signal parameter. The preset hardware signal parameter can represent the pre-configured signal parameter that meets the refresh mode switching. That is, when the control pin signal parameter belongs to the preset pin signal parameter, it means that the control pin signal parameter is the signal parameter that meets the pre-configured refresh mode switching. The mode switching instruction information can be determined based on the preset refresh mode switching instruction corresponding to the preset pin signal parameter. The refresh mode switching instruction represents the instruction for executing the refresh mode switching, that is, the refresh mode switching instruction can be used to instruct the display device to switch the refresh rate. When the control pin signal parameter does not belong to the preset pin signal parameter, it means that the control pin signal parameter is the signal parameter that does not meet the pre-configured refresh mode switching. At this time, the mode maintenance instruction can be determined as the mode switching instruction information. The mode maintenance instruction indicates the instruction that there is no need to execute the refresh mode switching, that is, the mode maintenance instruction can be used to instruct the display device to maintain the current refresh rate.

[0073] In one 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 it is determined whether the control pin signal parameter belongs to the preset pin signal parameter, that is, it is determined whether the control pin signal parameter is a high level parameter. 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 the preset 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, the mode maintenance instruction can be determined as the mode switching instruction information; in addition, multiple preset pin signal parameters can be pre-configured, and different preset pin signal parameters correspond to different refresh mode switching instructions, such as the refresh mode switching instruction A corresponding to the preset pin signal parameter A is used to indicate that the refresh rate of the display device is switched to a 120Hz refresh rate, and the refresh mode switching instruction B corresponding to the preset pin signal parameter B is used to indicate that the refresh rate of the display device is switched to a 240Hz refresh rate, etc. Of course, the above is only an example for illustration, and it can be adjusted according to the scene and requirements during specific implementation, and this embodiment does not make specific limitations on this.

[0074] In an optional embodiment of the present application, step S130 generates a target scan signal and a target pixel signal based on the mode switching instruction information, and may specifically include the following sub-steps: determining whether the mode switching instruction information is a refresh mode switching instruction; when the mode switching instruction information is a refresh mode switching instruction, obtaining the refresh screen row number information and refresh pixel data corresponding to the refresh mode switching instruction; determining the refresh scan signal corresponding to the refresh screen row number information, and determining the refresh scan signal as the target scan signal; and generating the target pixel signal using the refresh pixel data.

[0075] In this embodiment, after determining the mode switching instruction information, it can be determined whether the mode switching instruction information is a refresh mode switching instruction. If the mode switching instruction information is not a refresh mode switching instruction, it means that there is no need to switch the refresh mode at this time, and there is no need to execute subsequent steps; and if the mode switching instruction information is a refresh mode switching instruction, it means that the refresh mode needs to be switched at this time, and different refresh mode switching instructions can correspond to instructing the display device to switch to different refresh rate modes, so that the refresh screen row number information and refresh pixel data corresponding to the refresh mode switching instruction can be obtained, wherein the refresh screen row number information indicates the number of screen rows of the refresh rate mode corresponding to the refresh mode switching instruction, and the refresh pixel data indicates the pixel data of the refresh rate mode corresponding to the refresh mode switching instruction; then the refresh scan signal corresponding to the refresh screen row number information can be determined, and the refresh scan signal can be determined as the target scan signal, wherein the refresh scan signal indicates a signal for scanning the number of screen rows indicated by the refresh screen row number information; and the refresh pixel data is used to generate a target pixel signal, and the target pixel signal can indicate a pixel signal for output display.

[0076] In one example, if Figure 2 As shown, there are two refresh rate modes, normal mode (4K2K60HZ) and HSR mode (4K1K 120HZ). The two refresh rate modes have different refresh screen lines. The refresh screen lines in normal mode (4K2K 60HZ) are Figure 2 V_total1 in the upper middle part = V_active + V_blank = 2160 + 90 = 2250. The number of refresh lines in HSR mode (4K1K 120HZ) is Figure 2V_total2 in the lower part is V_active+V_blank=1080+45=1125, where V_total refers to the total number of lines of the display screen, 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 of the actual display content and the additional number of lines V_blank, which may be used for backlight control, screen refresh, synchronization signal transmission, etc. When the present embodiment is implemented, it is first determined whether the mode switching instruction information is a refresh mode switching instruction, and then when the mode switching instruction information is a refresh mode switching instruction, the refresh screen line number information and refresh pixel data corresponding to the refresh mode switching instruction are obtained. At this time, if the refresh mode switching instruction indicates that the display device switches to the HSR mode (4K1K120HZ) refresh rate mode, the HSR mode (4K1K The refresh screen row number V_total corresponding to the refresh rate mode of 120HZ) is determined as the refresh screen row number information, and a refresh scan signal corresponding to the refresh screen row number information is determined. The refresh scan signal can be used to scan the signal of V_total, specifically, the refresh scan clock signal can be refreshed, and the refresh scan signal is determined as the target scan signal; then the refresh pixel data can be used to generate the target pixel signal. Since the pixel data corresponding to different 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, such as Figure 2 As shown, if the refresh mode switching instruction is to instruct the display device to switch to the HSR mode (4K1K120HZ) refresh rate mode, then according to Figure 2 The refresh pixel data Data in the middle and lower parts generates the target pixel signal. If the refresh mode switching instruction is to instruct the display device to switch to the normal mode (4K2K60HZ) refresh rate mode, then according to Figure 2 The refresh pixel data Data in the upper middle part generates the target pixel signal. Of course, the above is only an example to illustrate the effect, and it can be adjusted according to the scene and requirements during the specific implementation, and this embodiment does not make specific limitations on this.

[0077] In an optional embodiment of the present application, step S140 uses a target scan signal and a target pixel signal to switch the display mode to obtain a display mode switching result corresponding to the display device, which may specifically include the following sub-steps: when the mode switching instruction information is a refresh mode switching instruction, obtaining the driving voltage management information corresponding to the display device; determining the target driving voltage corresponding to the refresh mode switching instruction based on the driving voltage management information; determining whether the target driving voltage matches the real-time voltage of the display device; when the target driving voltage does not match the real-time voltage of the display device, generating a voltage adjustment signal based on the target driving voltage; using the target scan signal, the target pixel signal and the voltage adjustment signal to switch the display mode to obtain the display mode switching result corresponding to the display device.

[0078] In this embodiment, during the display mode switching process, it can be determined whether the mode switching instruction information is a refresh mode switching instruction. When the mode switching instruction information is a refresh mode switching instruction, the driving voltage management information corresponding to the display device can be obtained. The driving voltage management information indicates the management information of the driving power supply corresponding to the display device when displaying at different refresh rates. Therefore, the target driving voltage corresponding to the refresh mode switching instruction can be determined based on the driving voltage management information. The target driving voltage indicates the driving voltage of the refresh mode corresponding to the refresh mode switching instruction. It is also determined whether the target driving voltage matches the real-time voltage of the display device. The real-time voltage may indicate the driving voltage of the display device used for display in real time. When the target driving voltage does not match the real-time voltage of the display device, it indicates that the real-time voltage of the display device cannot meet the driving voltage of the refresh mode corresponding to the refresh mode switching instruction of the refresh mode. At this time, a voltage adjustment signal can be generated based on the target driving voltage. The voltage adjustment signal may indicate an adjustment signal for adjusting the driving voltage of the display device. Then, the target scanning signal, the target pixel signal and the voltage adjustment signal can be used to switch the display mode to obtain the display mode switching result corresponding to the display device. That is, the display mode switching may also include the adjustment of the driving voltage of the display device.

[0079] Specifically, currently available display devices all include a power management integrated circuit (PMIC) control. When different display devices display at different refresh rates, their driving voltage may remain unchanged or may need to be adjusted, such as Figure 3As shown in the figure, the difference in driving voltage required by a display device in two refresh rate display modes, Normal mode and HSR mode. As can be seen from the figure, in the two refresh rate display modes of the display device, the panel-related voltages such as VGH / VGL are unchanged, while most of the voltages related to Sourcedriver, such as AVDD / HAVDD / VCOM / Gamma voltage, need to be switched with the refresh rate display mode. That is, when the mode switching instruction information is a refresh mode switching instruction, the driving voltage management information corresponding to the display device is obtained, and the driving voltage management information can be Figure 3 The information contained in the table, at this time, according to the driving voltage management information, the target driving voltage corresponding to the refresh mode switching instruction is determined, when the refresh mode switching instruction is to switch to the HSRmode refresh rate display mode, at this time, the AVDD voltage corresponding to the refresh mode switching instruction is determined to be 15V, that is, the target driving voltage is 15V, and the real-time voltage of the display device is collected to be 16V. At this time, the target driving voltage 15V does not match the real-time voltage 16V of the display device, then a voltage adjustment signal can be generated based on the target driving voltage, and then in the process of switching the display mode using the target scanning signal, the target pixel signal and the voltage adjustment signal, the AVDD voltage of the display device can be adjusted from 16V to 15V, and the display mode switching result corresponding to the display device is obtained. It can be seen that in this embodiment, different display devices can correspond to different driving voltage management information, and the same driving voltage management information can also include multiple target driving voltages corresponding to the refresh mode switching instruction, such as Figure 3 For each type of target driving voltage, the step of generating a voltage adjustment signal according to the target driving voltage can be performed when the target driving voltage does not match the real-time voltage of the display device. Of course, the above is only an example for explanation, and it can be adjusted according to the scene and requirements during specific implementation, and this embodiment does not make specific limitations on this.

[0080] In addition, when determining whether the target driving voltage matches the real-time voltage of the display device, the SOC can read back the register value A in the PMIC through I2C and compare it with the value to be written B. The register value A is the real-time voltage of the display device, and the value to be written B is the target driving voltage. When the register value A is equal to the value to be written B, it indicates that the target driving voltage matches the real-time voltage of the display device, and there is no need to generate a voltage adjustment signal at this time; when the register value A is not equal to the value to be written B, it indicates that the target driving voltage does not match the real-time voltage of the display device. At this time, a voltage adjustment signal can be generated based on the target driving voltage. When the display mode is switched using the target scanning signal, the target pixel signal and the voltage adjustment signal, the SOC can write the value to be written B to the PMIC through I2C to obtain the display mode switching result corresponding to the display device.

[0081] In an optional embodiment of the present application, step S140 uses a target scan signal and a target pixel signal to switch the display mode to obtain a display mode switching result corresponding to the display device, which may specifically include the following sub-steps: obtaining display scan parameters and real-time pixel data of the display device; updating the display scan parameters based on the target scan signal to obtain target scan parameters; using the target pixel signal to update the real-time pixel data to obtain target pixel data; generating a display mode switching result based on the target scan parameters and the target pixel data.

[0082] In this embodiment, during the display mode switching process, the display scanning parameters and real-time pixel data of the display device can be obtained, wherein the display scanning parameters represent the parameters of the current pixel scanning of the display device, and the real-time pixel data represent the data of the current display pixel output of the display device; thereby, the display scanning parameters can be updated based on the target scanning signal to obtain the target scanning parameters, wherein the specific updating method can be to replace the display scanning parameters with the target scanning signal, and the obtained target scanning parameters can represent the updating of the display scanning parameters to the parameters of the target scanning signal; then, the target pixel signal can be used to update the real-time pixel data to obtain the target pixel data, wherein the specific updating method can be to replace the real-time pixel data with the target pixel signal, and the obtained target pixel data can represent the updating of the real-time pixel data to the data of the target pixel signal; and then, the display mode switching result can be generated based on the target scanning parameters and the target pixel data.

[0083] In one example, when the scanning parameter is a refresh scanning clock signal (Refresh Scan Clock Signal, CK), the display scanning parameter of the display device is obtained as the refresh scanning clock signal A, and the real-time pixel data of the display device is as follows: Figure 2 The upper part of the data Data shown in the figure, at this time the target scanning signal is the refresh scanning clock signal B, and the target pixel signal is as follows Figure 2 The lower half of the data Data shown in the figure, at this time, the display scanning parameters are updated based on the target scanning signal, which can be to update the display scanning parameters of the display device from the refresh scanning clock signal A to the refresh scanning clock signal B. More specifically, the refresh scanning clock signal A can be as follows Figure 2 The CKx in the upper part shown is V_total1, and the refresh scan clock signal B can be as follows: Figure 2 The CKx in the lower part shown is V_total2, and the target scanning parameter is obtained, that is, the refresh scanning clock signal B, and the real-time pixel data is updated using the target pixel signal, that is, using the following method: Figure 2 The lower part of the data shown replaces the real-time pixel data of the display device. Figure 2 The upper half of the data Data shown generates the display mode switching result.

[0084] In an optional embodiment of the present application, a display mode switching result is generated based on the target scanning parameters and the target pixel data, which may specifically include the following sub-steps: controlling the display device to output the screen based on the target scanning parameters and the target pixel data, and collecting the screen scanning parameters of the display device; when the screen scanning parameters match the target scanning parameters, determining the display mode switching success result as the display mode switching result; when the screen scanning parameters do not match the target scanning parameters, determining the display mode switching failure result as the display mode switching result.

[0085] In the present embodiment, in the specific process of generating the display mode switching result based on the target scanning parameters and the target pixel data, the display device can be controlled to output the screen based on the target scanning parameters and the target pixel data, and the screen scanning parameters of the display device can be collected. The screen scanning parameters represent the scanning parameters collected when the display device is outputting the screen, so as to judge whether the screen scanning parameters match the target scanning parameters, thereby playing a role in judging whether the display scanning parameters are successfully updated. When the screen scanning parameters match the target scanning parameters, it means that the display scanning parameters have been successfully updated. At this time, the display mode switching success result can be determined as the display mode switching result. If the screen scanning parameters do not match the target scanning parameters, it means that the display scanning parameters have not been successfully updated. At this time, the display mode switching failure result can be determined as the display mode switching result.

[0086] In one example, in the process of controlling the display device to output a picture according to the target scanning parameter and the target pixel data, when the target scanning signal is Figure 2When the screen scan parameter is matched with the target scan parameter, that is, V_totalX matches with V_total2, it indicates that the display scan parameter has been successfully updated, that is, V_total2 has been successfully written into the V total value in the SOC chip. At this time, the display mode switching success result can be determined as the display mode switching result. When the screen scan parameter does not match with the target scan parameter, that is, V_totalX does not match with V_total2, it indicates that the display scan parameter has not been successfully updated, that is, V_total2 has not been successfully written into the V total value in the SOC chip. At this time, the display mode switching failure result can be determined as the display mode switching result.
