[0003] This application relates to the field of display technology, and more specifically, to display voltage adjustment methods, program products, electronic devices, and storage media. Background Technology

[0004] AMOLED displays use self-emissive technology, where each pixel can emit light independently. During the display process, the display driver IC processes the received image and outputs a corresponding analog voltage to each pixel, driving each pixel of the display to perform the display based on the analog voltage.

[0005] With the continuous upgrading of screen manufacturing materials and the improvement of production processes, the accuracy requirements for analog voltages in displays are also increasing. When the accuracy of the analog voltage does not meet the actual requirements, the accuracy of the output analog voltage is usually improved by modifying the display driver integrated circuit. However, improving the display driver integrated circuit is costly in terms of time and manpower.

[0006] Application content

[0007] In view of this, the purpose of this application is to provide a display voltage adjustment method, program product, electronic device and storage medium to solve the technical problem of high cost required by existing methods for improving the accuracy of analog output voltage.

[0008] In a first aspect, embodiments of this application provide a display voltage adjustment method, the method comprising:

[0009] Based on the image to be displayed, determine the pixel voltage level of each pixel on the target display screen;

[0010] The adjustment level of the pixel voltage level is determined based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage.

[0011] Based on the adjustment level, the actual analog voltage corresponding to the pixel is adjusted; wherein, the actual analog voltage is used to drive the target display screen to display the image to be displayed.

[0012] In the above implementation process, the display voltage adjustment method determines the pixel voltage level of each pixel on the target display screen based on the image to be displayed; determines the adjustment level of the pixel voltage level based on the theoretical analog voltage and the test analog voltage corresponding to the theoretical analog voltage; and adjusts the actual analog voltage corresponding to the pixel based on the adjustment level. This display voltage adjustment method can quickly determine the corresponding adjustment level based on the test analog voltage and the theoretical analog voltage; and adjusts the actual analog voltage of the pixel based on the adjustment level to improve the accuracy of the output analog voltage; it requires relatively low time and labor costs. It solves the technical problem of high time and labor costs required by existing methods for improving the accuracy of analog output voltage. Furthermore, this display voltage adjustment method is not limited by the type of display screen, making it more applicable.

[0013] Optionally, in this embodiment, the screen to be displayed includes a theoretical frame screen and an adjustment frame screen; adjusting the actual analog voltage corresponding to the pixel based on the adjustment level includes: when the screen to be displayed is the theoretical frame screen, controlling the display driving circuit to output the test analog voltage to the pixel based on the pixel voltage level; when the screen to be displayed is the adjustment frame screen, controlling the display driving circuit to output the adjustment analog voltage to the pixel based on the adjustment level.

[0014] In the above implementation process, when the image to be displayed is a theoretical frame image, the display driving circuit is controlled to output a test analog voltage to the pixel based on the pixel voltage level; when the image to be displayed is an adjustment frame image, the display driving circuit is controlled to output an adjustment analog voltage to the pixel based on the adjustment level; thus, the actual analog voltage received by the pixel can be adjusted to improve the accuracy of the output actual analog voltage.

[0015] Optionally, in this embodiment of the application, during the process of the target display screen being in display state, the theoretical frame and the adjustment frame appear cyclically according to a preset adjustment cycle.

[0016] In the above implementation process, by setting theoretical frame images and adjustment frame images to appear cyclically according to a preset adjustment cycle, the accuracy of the output actual analog voltage can be improved while reducing the computational load of the corresponding display system server.

[0017] Optionally, in the embodiments of this application, the theoretical frame includes either an odd-numbered frame or an even-numbered frame, and the adjusted frame includes either an odd-numbered frame or an even-numbered frame.

[0018] In the above implementation process, by setting the theoretical frame to include either an odd number of frames or an even number of frames, and adjusting the frame to include either an odd number of frames or an even number of frames, the computational load can be reduced while improving the accuracy of the actual display voltage adjustment.

[0019] Optionally, in this embodiment of the application, the display screen to be displayed is a display screen in RGB color mode; the pixel voltage level includes R channel voltage level, G channel voltage level and B channel voltage level;

[0020] The step of determining the adjustment level of the pixel voltage level based on the theoretical simulated voltage corresponding to the pixel voltage level and the test simulated voltage corresponding to the theoretical simulated voltage includes: determining a first adjustment level of the R-channel voltage level based on the R-channel theoretical simulated voltage corresponding to the R-channel voltage level and the R-channel test simulated voltage corresponding to the R-channel theoretical simulated voltage; determining a second adjustment level of the G-channel voltage level based on the G-channel theoretical simulated voltage corresponding to the G-channel theoretical simulated voltage and the G-channel test simulated voltage corresponding to the G-channel theoretical simulated voltage; and determining a third adjustment level of the B-channel voltage level based on the B-channel theoretical simulated voltage corresponding to the B-channel voltage level and the B-channel test simulated voltage corresponding to the B-channel theoretical simulated voltage.

[0021] In the above implementation process, when the display screen to be displayed is an RGB color mode display screen, the first adjustment level of the R channel voltage level, the second adjustment level of the G channel voltage level, and the third adjustment level of the B channel voltage level are calculated respectively; based on the first adjustment level, the second adjustment level, and the third adjustment unit corresponding to different channels, the actual analog voltage corresponding to the pixel is adjusted; and the target display screen is driven to display the RGB color mode display screen based on the adjusted actual analog voltage.

[0022] Optionally, in this embodiment of the application, adjusting the actual analog voltage corresponding to the pixel based on the adjustment level includes: adjusting the R-channel actual analog voltage, G-channel actual analog voltage, and B-channel actual analog voltage corresponding to the pixel based on the first adjustment level, the second adjustment level, and the third adjustment level, respectively; wherein, the R-channel actual analog voltage, G-channel actual analog voltage, and B-channel actual analog voltage are used to drive the target display screen to display the image to be displayed.

[0023] In the above implementation process, the actual analog voltage of different channels is adjusted by the first adjustment level, the second adjustment level and the third adjustment level, so as to drive different channels to display the screen to be displayed based on the actual analog voltage of the R channel, the actual analog voltage of the G channel and the actual analog voltage of the B channel.

[0024] Optionally, in this embodiment of the application, determining the adjustment level of the pixel voltage level based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage includes: when the theoretical analog voltage is greater than or equal to the minimum adjustment voltage and less than or equal to the maximum adjustment voltage, determining the adjustment level of the pixel voltage level based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage.

[0025] In the above implementation process, since the display screen has low sensitivity to analog voltage changes when its brightness is in the end brightness range (brighter and dimmer), the adjustment level of the pixel voltage is determined by ensuring that the theoretical analog voltage is greater than or equal to the minimum adjustment voltage and less than or equal to the maximum adjustment voltage. This allows for adjustment of the actual analog voltage corresponding to the pixel based on the adjustment level. This reduces the computational load while maintaining the accuracy of the actual display voltage adjustment.

[0033] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the embodiments of this application will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0035] Figure 2 is a schematic flowchart of a display voltage adjustment method provided in an embodiment of this application;

[0036] Figure 3 is a schematic diagram of the analog voltage provided in an embodiment of this application;

[0037] Figure 4 is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0038] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0040] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0041] Please refer to Figure 1, which is a schematic diagram of a display system provided in an embodiment of this application. The driver IC (driver integrated circuit) is responsible for outputting a corresponding analog voltage through its analog voltage output port after receiving the display screen sent by the server, in order to control the display screen to display the image to be displayed.

[0042] The server sends digital signals for display, while the screen display requires analog voltage. The driver IC processes the received display data to obtain the corresponding digital voltage, which is then converted into analog voltage by a digital-to-analog converter module. This analog voltage is then output through the analog voltage output port. Different screen resolutions require different numbers of analog voltage output ports, and each port needs to output all analog voltages equally. Due to practical considerations such as circuit area, cost, and design complexity, the driver IC cannot create a voltage divider circuit for every analog voltage output port to meet its voltage requirements. A hierarchical approach is generally used. In the first stage, a resistor divider is used to generate a shared M-level voltage. In the second stage, an independent N-level voltage divider is created for each analog voltage output port. Finally, the output is handled by an operational amplifier to meet the M*N level analog voltage requirements.

[0043] Please refer to Figure 2, which shows a flowchart of a display voltage adjustment method provided in an embodiment of this application. Exemplarily, this display voltage adjustment method can be applied to a server in a display system. It can process display data based on the server to obtain the voltage level of each pixel and control the analog voltage output port of the driver IC to output an analog voltage at the corresponding voltage level. Specifically, this display voltage adjustment method may include the following steps:

[0044] S101. Determine the pixel voltage level of each pixel on the target display screen based on the image to be displayed;

[0045] S102. Determine the adjustment level of the pixel voltage level based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage.

[0046] S103. Based on the adjustment level, adjust the actual analog voltage corresponding to the pixel; wherein, the actual analog voltage is used to drive the target display screen to display the image to be displayed.

[0047] In step 101, the image to be displayed can be a grayscale color mode, an RGB color mode, or another color mode. Different voltage levels correspond to different ranges of pixel values. The display pixel value of each pixel can be determined based on the image to be displayed; and the pixel voltage level of that pixel can be determined based on the display pixel value.

[0048] In step 102, the adjustment level of the pixel voltage level can be determined based on the relationship between the theoretical analog voltage and the test analog voltage corresponding to the pixel voltage level. For example, if the theoretical analog voltage corresponding to the pixel voltage level is greater than the test analog voltage, the larger voltage level can be determined as the adjustment level; if the theoretical analog voltage corresponding to the pixel voltage level is less than the test analog voltage, the smaller voltage level can be determined as the adjustment level; if the theoretical analog voltage corresponding to the pixel voltage level is equal to the test analog voltage, the adjustment level is the same as the pixel voltage level. Specifically, the theoretical analog voltage corresponding to the larger voltage level is greater than the theoretical analog voltage corresponding to the pixel voltage level, and the theoretical analog voltage corresponding to the smaller voltage level is less than the theoretical analog voltage corresponding to the pixel voltage level. The adjustment level can be determined based on parameters such as the relationship between the theoretical analog voltage and the test analog voltage corresponding to the pixel voltage level, and the magnitude of the absolute difference between the theoretical analog voltage and the test analog voltage corresponding to the pixel voltage level.

[0049] In step 103, the actual analog voltage can be adjusted by outputting the analog output voltage corresponding to the adjustment level; in this adjustment method, the actual analog voltage includes the analog output voltage corresponding to the adjustment level. Alternatively, the actual analog voltage can be adjusted by alternately outputting the test output voltage corresponding to the pixel voltage level and the analog output voltage corresponding to the adjustment level; in this adjustment method, the actual analog voltage includes the alternately output test output voltage corresponding to the pixel voltage level and the analog output voltage corresponding to the adjustment level. This application does not specifically limit this method.

[0050] In cases where the difference between the theoretical analog voltage and the test analog voltage corresponding to a pixel voltage level is too large, the accuracy of the actual output analog voltage can be improved by directly outputting the analog output voltage corresponding to the adjustment level. Conversely, if the difference between the theoretical analog voltage and the test analog voltage corresponding to a pixel voltage level is small, and directly outputting the analog output voltage corresponding to the adjustment level cannot improve the accuracy of the actual output analog voltage, the test output voltage corresponding to the pixel voltage level and the analog output voltage corresponding to the adjustment level can be alternately output. This allows the human eye to perceive the display effect corresponding to the analog output voltage between the "test output voltage corresponding to the pixel voltage level and the analog output voltage corresponding to the adjustment level," thereby improving the accuracy of the actual output analog voltage and achieving a better display effect. The alternation method of the "test output voltage corresponding to the pixel voltage level and the analog output voltage corresponding to the adjustment level" can be adjusted according to the actual application, and this application does not impose specific limitations on it.

[0051] Therefore, the display voltage adjustment method provided in this application can quickly determine the corresponding adjustment level based on the tested analog voltage and the theoretical analog voltage; according to the adjustment level, the actual analog voltage of the pixel is adjusted to improve the accuracy of the output analog voltage; the required time and labor costs are low. This solves the technical problem of high time and labor costs required by existing methods for improving the accuracy of analog output voltage. Furthermore, this display voltage adjustment method is not limited by the type of display screen, making it more applicable.

[0052] Please refer to Figure 3, which is a schematic diagram of the simulated voltage provided in an embodiment of this application. Figure 3 merely illustrates, exemplarily, the theoretical simulated voltage, test simulated voltage, and adjustment simulated voltage corresponding to nine different pixel voltage levels. As shown in Figure 3, the theoretical simulated voltage and test simulated voltage of the first, fifth, and ninth levels are consistent. In this case, the adjustment level is the same as the pixel voltage level. The test simulated voltage of the third level is lower than the theoretical simulated voltage, so the adjustment level of the third level is determined to be the second level; the test simulated voltage of the seventh level is lower than the theoretical simulated voltage, so the adjustment level of the seventh level is determined to be the eighth level. When the pixel voltage level of the target pixel is the third level, by controlling the display driving circuit to output the test simulated voltage to the target pixel based on the pixel voltage level (third level) in odd-numbered frames, and by controlling the display driving circuit to output the adjustment simulated voltage to the target pixel based on the adjustment level (second level) in even-numbered frames, the human eye can perceive the display effect corresponding to the visual simulated voltage between the test simulated voltage and the adjustment simulated voltage. As shown in Figure 3, the display voltage adjustment method provided in this application can improve the linearity between different levels of analog output voltage, thereby improving the accuracy of the actual analog voltage output by the display driving circuit and obtaining a better display effect.

[0053] In some optional embodiments, the screen to be displayed includes a theoretical frame screen and an adjustment frame screen; S103, adjusting the actual analog voltage corresponding to the pixel based on the adjustment level includes: when the screen to be displayed is the theoretical frame screen, controlling the display driving circuit to output the test analog voltage to the pixel based on the pixel voltage level; when the screen to be displayed is the adjustment frame screen, controlling the display driving circuit to output the adjustment analog voltage to the pixel based on the adjustment level.

[0054] The occurrence frequencies of the theoretical frame and the adjusted frame can be the same or different (for example, the occurrence frequency of the theoretical frame can be twice that of the adjusted frame). The occurrence frequencies of the theoretical frame and the adjusted frame can be determined based on practical application parameters such as the "relationship between the theoretical analog voltage and the test analog voltage corresponding to the pixel voltage level" and the "absolute difference between the theoretical analog voltage and the test analog voltage corresponding to the pixel voltage level". By controlling the display driving circuit to output test analog voltage to the pixels when the image to be displayed is a theoretical frame, and controlling the display driving circuit to output adjusted analog voltage to the pixels when the image to be displayed is an adjusted frame, the human eye can perceive the display effect corresponding to the analog output voltage between the "test analog voltage and the adjusted analog voltage", thereby improving the accuracy of the actual output analog voltage and obtaining a better display effect.

[0055] In some optional embodiments, while the target display screen is in the display state, the theoretical frame and the adjustment frame appear cyclically according to a preset adjustment cycle.

[0056] The preset adjustment period can be 3 frames, 5 frames, or other reasonable values. For example, the theoretical frame may include frames 3K-1 and 3K-2, and the adjustment frame may include frame 3K; where K is a positive integer. By setting the theoretical and adjustment frames to appear cyclically according to the preset adjustment period, the accuracy of the output analog voltage can be improved while reducing the computational load on the corresponding display system server.

[0057] In some alternative embodiments, the theoretical frame includes either an odd-numbered frame or an even-numbered frame, and the adjusted frame includes either an odd-numbered frame or an even-numbered frame.

[0058] The theoretical frame may include odd-numbered frames, while the adjusted frame may include even-numbered frames; or, the theoretical frame may include even-numbered frames, while the adjusted frame may include odd-numbered frames; this application does not specifically limit this.

[0059] In some optional embodiments, the display screen to be displayed is an RGB color mode display screen; the pixel voltage level includes an R-channel voltage level, a G-channel voltage level, and a B-channel voltage level; the above-mentioned S102, determining the adjustment level of the pixel voltage level according to the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage, includes: determining a first adjustment level of the R-channel voltage level according to the R-channel theoretical analog voltage corresponding to the R-channel voltage level and the R-channel test analog voltage corresponding to the R-channel theoretical analog voltage; determining a second adjustment level of the G-channel voltage level according to the G-channel theoretical analog voltage corresponding to the G-channel theoretical analog voltage and the G-channel test analog voltage corresponding to the G-channel theoretical analog voltage; and determining a third adjustment level of the B-channel voltage level according to the B-channel theoretical analog voltage corresponding to the B-channel theoretical analog voltage and the B-channel test analog voltage corresponding to the B-channel theoretical analog voltage.

[0060] Specifically, the first adjustment level of the R-channel voltage range can be determined based on the relationship between the theoretical simulated voltage and the test simulated voltage of the R-channel corresponding to the R-channel voltage range. For example, if the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range is greater than the test simulated voltage of the R-channel, the larger channel voltage range can be determined as the first adjustment level; if the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range is less than the test simulated voltage of the R-channel, the smaller channel voltage range can be determined as the first adjustment level. The theoretical simulated voltage of the R-channel corresponding to the larger channel voltage range is greater than the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range, and the theoretical simulated voltage of the R-channel corresponding to the smaller channel voltage range is less than the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range. The first adjustment level can be specifically determined based on parameters such as the relationship between the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range and the test simulated voltage of the R-channel, as well as the magnitude of the absolute difference between the theoretical simulated voltage of the R-channel corresponding to the R-channel voltage range and the test simulated voltage of the R-channel. The methods for determining the second and third adjustment gears can refer to the above description of the method for determining the first adjustment gear. To avoid repetition, detailed descriptions are omitted here.

[0061] In some optional embodiments, the above-mentioned S103, adjusting the actual analog voltage corresponding to the pixel based on the adjustment level, includes: adjusting the actual analog voltage of the R channel, the actual analog voltage of the G channel, and the actual analog voltage of the B channel corresponding to the pixel based on the first adjustment level, the second adjustment level, and the third adjustment level, respectively; wherein the actual analog voltage of the R channel, the actual analog voltage of the G channel, and the actual analog voltage of the B channel are used to drive the target display screen to display the image to be displayed.

[0062] The actual analog voltage of the R channel can be adjusted by outputting the analog output voltage corresponding to the first adjustment level. In this adjustment method, the actual analog voltage of the R channel includes the analog output voltage corresponding to the first adjustment level. Alternatively, the actual analog voltage of the R channel can be adjusted by alternately outputting the R channel test output voltage corresponding to the R channel voltage level and the analog output voltage corresponding to the first adjustment level. In this adjustment method, the actual analog voltage of the R channel includes the alternately output R channel test output voltage corresponding to the R channel voltage level and the analog output voltage corresponding to the first adjustment level. For example, when the image to be displayed is a theoretical frame image, the display driving circuit can be controlled to output the R channel test output voltage to the pixel based on the R channel voltage level; when the image to be displayed is an adjustment frame image, the display driving circuit can be controlled to output the analog output voltage corresponding to the first adjustment level to the pixel based on the first adjustment level. The adjustment methods for the actual analog voltage of the G channel and the actual analog voltage of the B channel can refer to the above description of the adjustment method for the actual analog voltage of the R channel; to avoid repetition, detailed descriptions are omitted here.

[0063] In some optional embodiments, S102, determining the adjustment level of the pixel voltage level based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage, includes: when the theoretical analog voltage is greater than or equal to the minimum adjustment voltage and less than or equal to the maximum adjustment voltage, determining the adjustment level of the pixel voltage level based on the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage.

[0064] The minimum adjustment voltage can be 1.8V, 2.6V, or other reasonable values, while the maximum adjustment voltage can be 3.5V, 4.2V, or other reasonable values. The specific values ​​of the minimum and maximum adjustment voltages can be determined based on parameters such as the actual display model or screen manufacturing material. Since the display screen is less sensitive to analog voltage changes when its brightness is in the lower end of the brightness range (brighter and dimmer), the adjustment level of the pixel voltage is determined by ensuring that the theoretical analog voltage is greater than or equal to the minimum adjustment voltage and less than or equal to the maximum adjustment voltage. This allows for adjustment of the actual analog voltage corresponding to each pixel based on the adjustment level. This reduces the computational load while maintaining the accuracy of the actual display voltage adjustment.

[0065] This application embodiment also provides a display voltage adjustment device, which includes: a voltage level determination module configured to determine the pixel voltage level of each pixel of the target display screen according to the image to be displayed; an adjustment level determination module configured to determine the adjustment level of the pixel voltage level according to the theoretical analog voltage corresponding to the pixel voltage level and the test analog voltage corresponding to the theoretical analog voltage; and a voltage adjustment module configured to adjust the actual analog voltage corresponding to the pixel based on the adjustment level; wherein the actual analog voltage is used to drive the target display screen to display the image to be displayed.
