Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a driving method, a display device, a display equipment and a storage medium. Background Art

[0002] Currently, liquid crystal displays are popular among users. However, during the use of liquid crystal displays, the driving circuit of the liquid crystal display will display differently at the boundary where the sub-pixel polarity distribution is discontinuous than in other areas during the polarity switching process of its sub-pixels, resulting in vertical stripes or abnormal images on the liquid crystal display, which greatly affects the display effect. Summary of the Invention

[0003] The object of the present invention is to provide a driving method, a display device, a display equipment and a storage medium, which reduce dark lines on a display screen.

[0004] To achieve the purpose of the present invention, the present invention provides the following technical solutions: In a first aspect, the present invention provides a driving method, which is applied to a driving circuit of a display device, wherein the display device includes a screen driving module, a system chip module, a display module, and a plurality of sub-pixels, wherein the screen driving module is connected to the driving circuit, the system chip module, and the display module, and the screen driving module is used to transmit a first gamma correction voltage and a second gamma correction voltage, wherein the plurality of sub-pixels are connected to the driving circuit, and the plurality of sub-pixels include a first sub-pixel in the nth row, and the system chip module is used to output a first voltage of the first sub-pixel to the screen driving module, and the method includes: The driving circuit includes at least two sub-driving circuits, and the x-th routing is determined based on the at least two sub-driving circuits, and the polarity of the sub-pixel corresponding to the x-th routing is the same as the polarity of the sub-pixel corresponding to the x+1-th routing; the second voltage is determined through the voltage-related quantity of the sub-pixels in the first row of the x+1-th routing to the voltage-related quantity of the sub-pixels in the n-th row; the first preset value is determined based on the display grayscale of the first sub-pixel in the n-th row corresponding to the x-th routing; the third voltage is determined based on the second voltage, the first preset value and the first voltage; and the display module is controlled to transmit the third voltage to the first sub-pixel.

[0005] In this embodiment, the composition and connection relationship of each module of the display device are clarified, and the x-th routing is determined based on at least two sub-driving circuits, and the polarity of the sub-pixel corresponding to the x-th routing is the same as the polarity of the sub-pixel corresponding to the x+1-th routing; the second voltage is determined by the voltage-related quantity of the first row of sub-pixels on the x+1-th routing to the voltage-related quantity of the sub-pixels in the n-th row; the first preset value is determined based on the display grayscale of the first sub-pixel in the n-th row corresponding to the x-th routing; the first voltage is adjusted by the second voltage and the first preset value to obtain a third voltage; the display module is controlled to transmit the third voltage to the first sub-pixel, compensate for the first voltage of the first sub-pixel, thereby realizing the enhancement of the display brightness of the first sub-pixel, avoiding the generation of dark lines in the display screen of the display device, thereby improving the quality of the display screen and making the display effect more accurate.

[0006] In a possible example, determining the xth trace based on at least two of the sub-driving circuits includes: The at least two sub-driving circuits include a first sub-driving circuit and a second sub-driving circuit connected to each other; The xth routing line is determined based on the first routing line of the second sub-driving circuit; or, the xth routing line is determined based on polarities of at least two routing lines within the sub-driving circuit.

[0007] In this embodiment, the xth routing line is determined by the first routing line of the second sub-driving circuit; or, the xth routing line is determined based on the polarity of the routing lines in at least two sub-driving circuits. This determination method makes the selection of the xth routing line more clear, accurate, and targeted, thereby improving the efficiency and accuracy of determining the xth routing line.

[0008] In a possible example, determining the second voltage by using the voltage-related quantities of the sub-pixels in the first row to the voltage-related quantities of the sub-pixels in the nth row of the x+1th routing includes: The voltage-related quantities of the sub-pixels in the first row of the x+1-th wiring to the voltage-related quantities of the sub-pixels in the n-th row are summed to obtain the second voltage.

[0009] In this embodiment, it is clearly determined by summing the voltage-related quantities of the first row of sub-pixels of the x+1th line to the voltage-related quantities of the nth row of sub-pixels, thereby more accurately compensating the voltage of the first sub-pixel, improving the accuracy of the display effect, avoiding display abnormalities caused by unreasonable local voltages, and avoiding the generation of dark lines in the display screen of the display device.

[0010] In a possible example, summing the voltage-related quantities of the sub-pixels in the first row of the x+1th wiring to the voltage-related quantities of the sub-pixels in the nth row to obtain the second voltage includes: Un=[Un+ -U k +(U n- -U j )] / 2, Un is the voltage-related quantity of the sub-pixel in the nth row of the x+1th wiring, and U n+ is the positive polarity voltage of the sub-pixel in the nth row corresponding to the x+1th wiring, and the U n- is the negative polarity voltage of the sub-pixel in the nth row corresponding to the x+1th wiring, and the U k is the first gamma correction voltage, the U j is the second gamma correction voltage.

[0011] In this embodiment, by considering the influence of the positive polarity voltage of the sub-pixel, the negative polarity voltage of the sub-pixel and the gamma voltage, this formulated calculation makes the process of determining the voltage-related quantity of the n-th row of sub-pixels in the x+1-th routing more scientific and accurate.

[0012] In a possible example, the voltage-related quantities of the sub-pixels in the first row of the x+1th wiring to the voltage-related quantities of the sub-pixels in the nth row are summed to obtain the second voltage using the following formula: Vn=U1+U2+…+Un, wherein 1≤n≤i, Vn is the second voltage, and i is the total number of rows of the display module.

[0013] In this embodiment, the sum of the voltage-related quantities of the x+1th routing corresponding to different rows of sub-pixels is taken into account. Through this formula calculation method, the voltage situation of the x+1th routing can be more comprehensively analyzed, and the voltage-related quantities of multiple rows of sub-pixels are accumulated and summed, fully reflecting the voltage cumulative effect of the column routing at each sub-pixel position. This summation method can more accurately grasp the comprehensive impact of the x+1th routing on the second voltage, thereby making the obtained second voltage more accurate and the adjustment of the first voltage more precise, further optimizing the voltage control of the sub-pixels, improving the performance and display effect of the display device, and avoiding the generation of dark lines in the display screen of the display device.

[0014] In a possible example, determining the first preset value based on the display grayscale of the first sub-pixel in the nth row corresponding to the xth routing line includes: Setting a first lookup table based on the display device, wherein the first lookup table includes display grayscales of the first sub-pixels and the first preset values, and each display grayscale of the first sub-pixel corresponds to one of the first preset values ​​in a one-to-one manner; The first preset value is determined based on the first lookup table and the display grayscale of the first sub-pixel in the nth row corresponding to the xth line.

[0015] In this embodiment, the introduction of the first lookup table allows for the rapid and accurate acquisition of the first preset value corresponding to the grayscale displayed by the first sub-pixel, avoiding complex real-time calculations and improving the efficiency of the driving method. Furthermore, the first lookup table can be precisely pre-configured and calibrated based on the characteristics and requirements of the display device, enabling the first preset value to better match the actual requirements of the first sub-pixel at different grayscales. Consequently, when subsequently calculating the third voltage, the third voltage can be adjusted more precisely, further improving the accuracy and adaptability of the third voltage adjustment. This ensures that the displayed image maintains good display quality across a wide range of grayscales, enhancing the display quality and stability of the display device.

[0016] In a possible example, the third voltage is determined based on the second voltage, the first preset value, and the first voltage using the following formula: Va=Vb+Vc*Vn, where Va is the third voltage, Vb is the first voltage, and Vc is the first preset value.

[0017] In this embodiment, a specific formula for determining the third voltage based on the second voltage, the first preset value, and the first voltage is provided. Through this formulated combination, the key parameters obtained in the previous steps are accurately integrated. Specifically, this calculation formula enables the third voltage to more accurately meet the actual voltage requirements of the sub-pixels under the current display conditions, ensuring that each sub-pixel can obtain a suitable operating voltage, thereby optimizing the display effect of the display module, improving the quality and stability of the display image, enabling the display device to better present the expected image effect, and avoiding the generation of dark lines in the display image of the display device.

[0020] In a fourth aspect, an embodiment of the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program enables a computer to execute to implement the method provided in the first aspect or any embodiment of the first aspect.

[0031] See Figure 1 , Figure 1 This is a schematic diagram of an application scenario of a driving method provided in an embodiment of the present application. Figure 1 As shown, the application scenario diagram includes a user 101, a display device 102, and a server 103.

Server 103 may also be implemented as a server cluster consisting of multiple sub-servers.

[0033] It should be noted that Figure 1 The number and form of each device in the system shown, as well as the number of users 101, are for example only and do not constitute a limitation on the embodiments of the present application.

[0034] Please refer to Figure 2 , Figure 2 1 is a flow chart of a driving method provided by an embodiment of the present application. The method includes the following steps S201-S205, wherein the driving method is applied to a driving circuit of a display device, the display device including a screen driving module, a system chip module, a display module, and a plurality of sub-pixels, the screen driving module being connected to the driving circuit, the system chip module, and the display module, the screen driving module being configured to transmit a first gamma correction voltage and a second gamma correction voltage, the plurality of sub-pixels being connected to the driving circuit, the plurality of sub-pixels including a first sub-pixel in the nth row, and the system chip module being configured to output a first voltage of the first sub-pixel to the screen driving module.

[0035] It should be noted that the gamma correction voltage (Vgamma) is a key parameter that determines the shape of the entire grayscale voltage curve. It is usually evenly distributed within the positive and negative voltage range. The first gamma correction voltage is Vgamma7 and the second gamma correction voltage is Vgamma8.

[0036] S201: Determining an xth routing line based on at least two sub-driving circuits, including: The at least two sub-driving circuits include a first sub-driving circuit and a second sub-driving circuit connected to each other; The xth routing line is determined based on the first routing line of the second sub-driving circuit; or the xth routing line is determined based on the polarities of routing lines in at least two sub-driving circuits.

[0037] It should be noted that the multiple sub-pixels are arranged in an array on the driver circuit, and the driver circuit has multiple traces arranged in a sequentially spaced order. The sub-pixels in the Xth column of the multiple sub-pixels are respectively connected to the Xth trace, and a parasitic capacitor is connected between the sub-pixels in the Xth column and the X+1th trace. In addition, the first trace of the second sub-driver circuit is the trace on the second sub-driver circuit that is closest to the first sub-driver circuit.

[0038] It should be noted that the wiring is a data line, and the wiring is electrically connected to a plurality of sub-pixels.

[0039] It should be noted that this method is applied to a normal screen, which is a solid color screen. Usually, in this normal screen, the grayscale on adjacent traces does not change transiently, for example, the grayscale on adjacent traces does not change transiently from grayscale 0 to grayscale 255.

[0040] Optionally, the polarity of each routing line in at least two sub-driving circuits is obtained, the polarity of each adjacent routing line is compared, and two adjacent routing lines with the same polarity are found in at least two sub-driving circuits, thereby determining the xth routing line and the x+1th routing line. For example, a certain model of display screen includes 6 sub-driving circuits, and the 6 sub-driving circuits are responsible for 1920*3 routing lines, and each sub-driving circuit is responsible for 960 routing lines. The polarity distribution of the 960 routing lines that each sub-driving circuit is responsible for is continuous, and the change trend of each adjacent routing line in each sub-driving circuit is "-+-+", that is, the polarity is reversed. The polarity distribution of the two adjacent routing lines at the dividing line is discontinuous, for example, the polarity of the xth routing line is the same as the polarity of the x+1th routing line, and the change trend is "++", that is, the polarity remains unchanged. Since the number of adjacent routing lines with reversed polarity is much greater than the number of adjacent routing lines with the same polarity, the overall polarity change of the routing lines in the driving circuit is "-+-+", while the polarity change of routing lines x and x+1 is "++" is inconsistent with the overall polarity change trend, that is, the polarity distribution of routing lines x and x+1 is discontinuous.

[0041] Optionally, within the display device's driver circuit, the sub-driver circuits can be distributed, with the first and second sub-driver circuits placed on opposite sides of the panel, connected by signal transmission lines. The xth routing line is determined based on the first routing line on the side of the second sub-driver circuit closest to the first sub-driver circuit. For example, in an ultra-high-definition television panel, the first and second sub-driver circuits are distributed on the left and right sides. This arrangement shortens signal transmission distance, reduces signal delay and attenuation, improves driver efficiency, and ensures synchronized image display.

[0042] Alternatively, for a curved display panel, the sub-driver circuits can be connected to accommodate the curved surface. The first sub-driver circuit is located on the inside of the curve, while the second sub-driver circuit is located on the outside. These sub-driver circuits are connected via a flexible printed circuit board. For example, in a curved in-vehicle display, this layout ensures flexible and reliable signal transmission, allowing for distortion-free and latency-free display on the curved surface.

[0043] Optionally, in the transparent display panel of the display device, the first sub-driving circuit and the second sub-driving circuit are made of transparent conductive material and are connected by transparent wiring, which can ensure the normal implementation of the driving function without affecting the transparency of the panel.

[0044] Optionally, for a high refresh rate display panel of a display device, such as a gaming monitor with a refresh rate of 240Hz, the sub-driving circuit needs to respond quickly, and the first sub-driving circuit and the second sub-driving circuit use high-speed driving chips and are connected through high-speed signal transmission lines.

[0045] Optionally, in a foldable display panel of a display device, the first and second sub-driver circuits need to adapt to the folding action. The first sub-driver circuit is placed on one side of the folding axis, and the second sub-driver circuit is placed on the other side, connected by a retractable elastic wiring. This ensures continuity and stability of signal transmission during folding and unfolding, avoids wiring breakage or signal interruption due to folding, and ensures normal display of the display image.

[0046] Optionally, in a smart display panel of a display device, the first and second sub-driver circuits may integrate sensor interfaces. For example, integrating an ambient light sensor allows the display panel to automatically adjust its brightness based on ambient light intensity. In this case, the corresponding wiring must prioritize fast transmission of sensor signals to ensure that the display screen can adjust its brightness in real time based on environmental changes, thereby improving the user's visual experience.

[0047] In this embodiment, the xth routing line is determined by the first routing line of the second sub-driving circuit; or, the xth routing line is determined based on the polarity of the routing lines in at least two sub-driving circuits. This determination method makes the selection of the xth routing line more clear, accurate, and targeted, thereby improving the efficiency and accuracy of determining the xth routing line.

[0048] S202: Determining a second voltage by using voltage-related quantities of sub-pixels in the first row of the x+1th line to voltage-related quantities of sub-pixels in the nth row, including: The voltage-related quantities of the first row of sub-pixels on the x+1th wiring to the voltage-related quantities of the nth row of sub-pixels are summed to obtain a second voltage.

[0049] Alternatively, for display panels requiring fast response times, such as large-screen displays used for real-time data display, the summation operation must be completed extremely quickly. A summation circuit consisting of a high-speed operational amplifier and an analog-to-digital converter can be used to convert the sub-pixel voltage-related quantities of the x+1th trace into digital signals, and then perform the summation operation using a high-speed processor. For example, using an analog-to-digital converter with a sampling rate of millions of times per second, combined with a high-performance field-programmable gate array for summation, can obtain the second voltage within a few microseconds, ensuring real-time data update and display.

[0050] Optionally, in low-power display panel designs, such as e-book readers, the summation operation needs to consider power consumption. A low-power complementary metal oxide semiconductor (CMOS) circuit is used for summation. Leveraging the ability of CMOS circuits to operate even at low voltages, the sub-pixel voltage-related quantities on the x+1th trace are summed item by item. For example, in the driver circuit of an e-ink display, by properly designing the summation circuit, the power consumption of the entire summation process can be reduced to the milliwatt level, extending the battery life of the e-book.

[0051] Optionally, for touch-enabled display panels, touch signals may interfere with the summation operation. A filtering element, such as a low-pass filter, can be added to the display device's summation circuit to remove high-frequency interference from the touch signal. For example, in a touchscreen all-in-one computer, when a user touches the screen, the filter can effectively suppress the touch signal's interference with the summation of sub-pixel voltage-related quantities, ensuring the accuracy of the second voltage and avoiding display anomalies caused by the touch signal.

[0052] Optionally, in medical display panels requiring high-precision displays, the sub-pixel voltage-related quantities must be summed with high precision, employing a high-precision analog-to-digital converter and digital signal processor for the summation operation. For example, a 16-bit or higher-precision analog-to-digital converter can be used to sample the sub-pixel voltage-related quantities, and then a high-precision floating-point summation operation can be performed by the display device's digital signal processor. This ensures that the calculated accuracy of the second voltage reaches the microvolt level, making the display of medical images more accurate and clear, and facilitating precise diagnosis.

[0053] Optionally, when the display device is used in an intelligent display system, the summation operation can be optimized in conjunction with an artificial intelligence algorithm. For example, a machine learning algorithm can be used to predict the changing trend of the sub-pixel voltage-related quantity of the x+1th line, and the parameters of the summation algorithm can be adjusted in advance. When displaying dynamic content, such as video playback, the summation process is dynamically optimized based on the prediction results, improving the calculation efficiency and accuracy of the second voltage, and achieving a more intelligent and efficient display driver.

[0054] Optionally, for multi-panel splicing display systems, such as large video walls, the summation operation needs to consider the coordination of multiple panels. The sub-pixel voltage correlation quantities of the x+1th trace of each panel are summed separately, and then integrated to obtain the second voltage for the entire video wall. For example, the summation results of each panel are transmitted to a central controller via network communication. The central controller performs a unified integrated calculation to ensure uniform brightness and consistent color across the entire video wall, achieving a seamless display effect.

[0055] In this embodiment, it is clearly determined by summing the voltage-related quantities of the first row of sub-pixels of the x+1th wiring to the voltage-related quantities of the nth row of sub-pixels, thereby more accurately controlling the voltage of the sub-pixels, improving the uniformity and accuracy of the display effect, avoiding display abnormalities caused by unreasonable local voltages, and avoiding the generation of dark lines in the display screen of the display device.

[0056] Summing the voltage-related quantities of the first row of sub-pixels on the x+1th line to the voltage-related quantities of the nth row of sub-pixels to obtain a second voltage includes: Un=[U n+ -U k +(U n- -U j )] / 2, Un is the voltage related quantity of the nth row of sub-pixels in the x+1th line, U n+ is the positive polarity voltage of the nth row of sub-pixels corresponding to the x+1th line, U n- is the negative polarity voltage of the nth row of sub-pixels corresponding to the x+1th line, U k is the first gamma correction voltage, U j is the second gamma correction voltage.

[0057] Optionally, in high-contrast display panels, the difference between the positive and negative polarity voltages of subpixels is significant. When calculating the voltage-related quantities of the subpixels in the nth row, a high-precision voltmeter is used to measure the positive and negative polarity voltages, respectively, and then substitute these into the calculation formula. Simultaneously, the values ​​of the first and second gamma correction voltages are precisely controlled to ensure the accuracy of the calculated Un.

[0058] Optionally, for display panels of display devices that require fast screen switching, such as virtual reality displays, the calculation of Un needs to be completed quickly, and high-speed computing circuits, such as high-speed operational amplifiers and fast analog-to-digital converters, are used to perform fast sampling and calculations to ensure fast screen switching, reduce delays, and enhance user immersion.

[0059] Optionally, for a high color gamut display panel of a display device, such as a quantum dot display, the chromaticity of the sub-pixels varies greatly. When calculating Un, the effect of chromaticity on voltage needs to be considered. A correspondence between chromaticity and voltage is established through precise color calibration technology. For example, during the production process of a quantum dot display panel, each sub-pixel is color calibrated to obtain its positive and negative polarity voltage values ​​at different chromaticities. When calculating Un, based on the actual display color requirements, the corresponding positive polarity voltage of the nth row sub-pixel and the negative polarity voltage of the nth row sub-pixel are obtained from the calibration data, and substituted into the formula for calculation to ensure the accuracy and richness of the displayed colors.

[0060] Optionally, in the intelligent display system of a display device, the values ​​of the two gamma voltages can be dynamically adjusted to accommodate different display requirements. For example, when displaying a high-brightness image, the values ​​of the two gamma voltages can be appropriately increased, improving the calculated value of Un, enabling the sub-pixels to obtain higher drive voltages and improving brightness performance. Conversely, when displaying a low-brightness image, the values ​​of the two gamma voltages can be reduced to reduce power consumption. Intelligent algorithms monitor display content in real time, dynamically adjust gamma voltages, and optimize Un calculations, achieving intelligent display control.

[0061] In this embodiment, by considering the influence of the positive polarity voltage of the sub-pixel, the negative polarity voltage of the sub-pixel and the gamma voltage, this formulated calculation makes the process of determining the voltage-related quantity of the sub-pixels in the nth row more scientific and accurate, and can analyze the voltage-related quantity of each sub-pixel in more detail, thereby improving the accuracy of obtaining the voltage-related quantity of the sub-pixels in the nth row.

[0062] The voltage-related quantities of the first row of sub-pixels on the x+1th line to the voltage-related quantities of the nth row of sub-pixels are summed to obtain the second voltage using the following formula: Vn=U1+U2+…+Un, wherein 1≤n≤i, Vn is the second voltage, and i is the total number of rows of the display module.

[0063] Alternatively, for display panels requiring fast response times, such as e-sports monitors, the summation operation must be completed extremely quickly, employing a high-speed processor and a dedicated math chip. For example, the parallel computing capabilities of a graphics processor (GPU) can be used to rapidly sum sub-pixel voltage-related quantities. The GPU's massively parallel processing units can complete the summation of large amounts of data in milliseconds, ensuring timely updates of the second voltage and enabling the game screen to quickly respond to player actions.

[0064] Optionally, for a display panel with a touch-enabled display device, touch signals may interfere with the summation operation. A filtering element, such as a bandpass filter, can be added to the summation circuit to remove the frequency components of the touch signal. For example, in a touchscreen mobile phone, when a user touches the screen, the filter can effectively suppress the interference of the touch signal on the summation of sub-pixel voltage-related quantities, ensuring the accuracy of the second voltage, avoiding display anomalies caused by the touch signal, and improving the user experience.

[0065] Optionally, in intelligent display systems, the summation operation can be optimized in conjunction with a machine learning algorithm. By training the machine learning model, the changing trends of sub-pixel voltage-related quantities can be predicted, and the parameters of the summation algorithm can be adjusted in advance. For example, when displaying dynamic video, the changes in sub-pixel voltage-related quantities can be predicted based on the motion vectors of the video content, and the summation process can be dynamically optimized to improve the efficiency and accuracy of the calculation of the second voltage, thereby achieving a more intelligent and efficient display driver.

[0066] In this embodiment, the sum of the voltage-related quantities of the x+1th routing corresponding to different rows of sub-pixels is taken into account. Through this formula calculation method, the voltage situation of the x+1th routing can be more comprehensively analyzed, and the voltage-related quantities of multiple rows of sub-pixels are accumulated and summed, fully reflecting the voltage cumulative effect of the column routing at each sub-pixel position. This summation method can more accurately grasp the comprehensive impact of the x+1th routing on the second voltage, thereby making the obtained second voltage more accurate and the adjustment of the first voltage more precise, further optimizing the voltage control of the sub-pixels, improving the performance and display effect of the display device, and avoiding the generation of dark lines in the display screen of the display device.

[0067] S203: Determine a first preset value based on the display grayscale of the first sub-pixel in the nth row corresponding to the xth routing line.

[0068] In this embodiment, the introduction of the first lookup table allows for the rapid and accurate acquisition of the first preset value corresponding to the grayscale displayed by the first sub-pixel, avoiding complex real-time calculations and improving the efficiency of the driving method. Furthermore, the first lookup table can be precisely pre-configured and calibrated based on the characteristics and requirements of the display device, enabling the first preset value to better match the actual requirements of the first sub-pixel at different grayscales. Consequently, when subsequently calculating the third voltage, the third voltage can be adjusted more precisely, further improving the accuracy and adaptability of the third voltage adjustment. This ensures that the displayed image maintains good display quality across a wide range of grayscales, enhancing the display quality and stability of the display device.

[0069] Determining a first preset value based on a display grayscale of a first sub-pixel in the nth row corresponding to the xth line includes: A first lookup table is set based on the display device, wherein the first lookup table includes display grayscales of first sub-pixels and first preset values, and each display grayscale of the first sub-pixel corresponds to a first preset value in a one-to-one manner; A first preset value is determined based on the first lookup table and the display grayscale of the first sub-pixel in the nth row corresponding to the xth line.

[0070] Optionally, during the production of the display device, establishing a first lookup table is a key step. Based on the characteristics and design requirements of the display panel, the relationship between the displayed grayscale of each sub-pixel and the desired first preset value is accurately measured. For example, using professional calibration equipment, the electrical and optical characteristics of the sub-pixels at different grayscales are tested to obtain the corresponding first preset values. This data is stored in the driver circuit of the display panel to ensure that in actual use, the first preset value can be quickly and accurately obtained from the lookup table based on the displayed grayscale of the sub-pixel, thereby achieving precise drive control.

[0071] Optionally, for a display panel with a high refresh rate, such as a 240Hz gaming monitor, the first lookup table needs to be read very quickly. High-speed memory can be used to store the first lookup table, and the lookup algorithm can be optimized. For example, static random access memory can be used to store the first lookup table, with a read speed of nanoseconds. This ensures that the first preset value can be retrieved in a timely manner at high refresh rates, ensuring rapid updates of the displayed image and providing players with a smoother visual experience during gaming.

[0072] Optionally, for display panels of display devices requiring high-precision grayscale control, such as medical imaging displays, the first lookup table may need to include high-precision grayscale divisions. For example, the grayscale may be divided into multiple levels, and precise brightness and color measurements may be performed for each level to obtain the corresponding first preset value. This ensures more precise grayscale display of medical images and improves diagnostic accuracy.

[0073] S204: Determine a third voltage based on the second voltage, the first preset value, and the first voltage.

[0074] The third voltage is determined based on the second voltage, the first preset value, and the first voltage using the following formula: Va=Vb+Vc*Vn, Va is the third voltage, Vb is the first voltage, and Vc is the first preset value.

[0075] Alternatively, in high-resolution display panels, calculating the third voltage Va requires processing a large amount of data. Using a parallel computing architecture, multiple computing units simultaneously calculate Va for sub-pixels in different regions. For example, in an 8K display panel, multiple calculation regions are divided, each equipped with a computing unit, and the Va values ​​of each region are finally aggregated. This significantly improves calculation speed, meeting the real-time requirements of high-resolution display panels and ensuring smooth image display.

[0076] Alternatively, for display panels requiring fast response times, such as esports monitors, the third voltage calculation must be completed extremely quickly, employing a high-speed processor and a dedicated math chip. For example, the parallel computing capabilities of a graphics processor (GPU) can be leveraged to rapidly calculate the third voltage formula. The GPU's massively parallel processing units can calculate large amounts of data in milliseconds, ensuring timely updates of the third voltage and enabling the game screen to quickly respond to player actions.

[0077] Optionally, for a display panel with a touch-enabled display device, touch signals may interfere with the calculation of the third voltage. Therefore, a filtering element, such as a bandpass filter, is added to the calculation circuit to remove the frequency components of the touch signal. For example, in a touchscreen mobile phone, when a user touches the screen, the filter can effectively suppress the interference of the touch signal on the second voltage and the first preset value, ensuring the accuracy of the calculation of the third voltage, avoiding display anomalies caused by the touch signal, and improving the user experience.

[0078] In this embodiment, a specific formula for determining the third voltage based on the second voltage, the first preset value, and the first voltage is provided. Through this formulated combination, the key parameters obtained in the previous steps are accurately integrated. Specifically, this calculation formula enables the third voltage to more accurately meet the actual voltage requirements of the sub-pixels under the current display conditions, ensuring that each sub-pixel can obtain a suitable operating voltage, thereby optimizing the display effect of the display module, improving the quality and stability of the display image, enabling the display device to better present the expected image effect, and avoiding the generation of dark lines in the display image of the display device.
