Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a driving method, a display device, a display equipment, and a storage medium. Background Technology

[0002] Currently, LCD monitors are widely loved by users. However, during the use of LCD monitors, the driving circuit of the LCD monitor may display different images at the boundary of discontinuous sub-pixel polarity distribution compared to other areas during the polarity switching process of its sub-pixels. This can cause vertical lines or abnormal images to appear on the LCD monitor, greatly affecting the display effect. Summary of the Invention

[0003] The purpose of this invention is to provide a driving method, display device, display equipment, and storage medium that reduces dark lines on the displayed screen.

[0004] To achieve the objectives of this invention, the following technical solution is provided:

[0005] In a first aspect, the present invention provides a driving method applied to a driving circuit of a display device. The display device includes a screen driving module, a system chip module, a display module, and a plurality of sub-pixels. The screen driving module is connected to the driving circuit, the system chip module, and the display module. The screen driving module is used to transmit a first gamma correction voltage and a second gamma correction voltage. The plurality of sub-pixels are all connected to the driving circuit. The plurality of sub-pixels include a first sub-pixel in an nth row. The system chip module is used to output a first voltage of the first sub-pixel to the screen driving module. The method includes: The driving circuit includes at least two sub-driving circuits. Based on these at least two sub-driving circuits, an x-th trace is determined, where the polarity of the sub-pixel corresponding to the x-th trace is the same as that of the sub-pixel corresponding to the (x+1)-th trace. A second voltage is determined by the voltage correlation between the sub-pixels in the first row of the (x+1)-th trace and the voltage correlation between the sub-pixels in the n-th row. A 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 trace. A third voltage is determined based on the second voltage, the first preset value, and the first voltage. The display module is then controlled to transmit the third voltage to the first sub-pixel.

[0006] In this embodiment, the composition and connection relationship of each module of the display device are clearly defined. The x-th trace is determined based on at least two sub-driving circuits, and the polarity of the sub-pixel corresponding to the x-th trace is the same as that of the sub-pixel corresponding to the (x+1)-th trace. A second voltage is determined by the voltage correlation between the first row of sub-pixels of the (x+1)-th trace and the voltage correlation between the n-th row of sub-pixels. A 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 trace. 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, thereby compensating for the first voltage of the first sub-pixel, enhancing the display brightness of the first sub-pixel, avoiding dark lines in the display screen, improving the quality of the display screen, and making the display effect more accurate.

[0007] In one possible example, determining the x-th trace based on at least two of the said sub-driver circuits includes:

[0008] At least two of the said sub-driving circuits include a first sub-driving circuit and a second sub-driving circuit connected to each other;

[0009] The x-th trace is determined based on the first trace of the second sub-driving circuit; or, the x-th trace is determined based on the polarity of traces within at least two of the sub-driving circuits.

[0010] In this embodiment, the x-th trace is determined by the first trace of the second sub-driving circuit; or, the x-th trace is determined based on the polarity of traces in at least two sub-driving circuits. This determination method makes the selection of the x-th trace more explicit, accurate and targeted, improving the efficiency and accuracy of determining the x-th trace.

[0011] In one possible example, determining the second voltage by measuring the voltage correlation between the sub-pixels in the first row of the (x+1)th trace and the voltage correlation between the sub-pixels in the nth row includes:

[0012] The voltage correlation values ​​of the sub-pixels in the first row of the (x+1)th trace to the voltage correlation values ​​of the sub-pixels in the nth row are summed to obtain the second voltage.

[0013] In this embodiment, it is clarified that the second voltage is determined by summing the voltage correlation values ​​of the first row sub-pixels of the (x+1)th line to the voltage correlation values ​​of the nth row sub-pixels, thereby more accurately compensating for the voltage of the first sub-pixels, improving the accuracy of the display effect, avoiding display abnormalities caused by unreasonable local voltages, and preventing dark lines from appearing in the display screen of the display device.

[0014] In one possible example, summing the voltage correlation values ​​of the sub-pixels in the first row of the (x+1)th trace to the voltage correlation values ​​of the sub-pixels in the nth row to obtain the second voltage includes:

[0015] Un=[U n+ -U k +(U n- -U j )] / 2, where Un is the voltage-related quantity of the sub-pixel in the nth row of the (x+1)th trace, and U n+ The positive polarity voltage of the sub-pixel in the nth row corresponding to the (x+1)th trace, the U n- The negative polarity voltage of the sub-pixel in the nth row corresponding to the (x+1)th trace, the U k The first gamma correction voltage, the U j This is the second gamma correction voltage.

[0016] In this embodiment, by taking into account the effects of the positive polarity voltage, the negative polarity voltage, and the gamma voltage of the sub-pixel, this formulaic calculation makes the determination of the voltage-related quantities of the nth row sub-pixel of the (x+1)th trace more scientific and accurate.

[0017] In one possible example, the second voltage is obtained by summing the voltage correlation values ​​of the sub-pixels in the first row of the (x+1)th trace to the voltage correlation values ​​of the sub-pixels in the nth row, using the following formula:

[0018] Vn = U1 + U2 + ... + Un, where 1 ≤ n ≤ i, Vn is the second voltage, and i is the total number of rows of the display module.

[0019] In this embodiment, the sum of voltage-related quantities of sub-pixels corresponding to different rows of the (x+1)th trace is considered. By using this formula calculation method, the voltage situation of the (x+1)th trace can be analyzed more comprehensively. By summing the voltage-related quantities of sub-pixels in multiple rows, the cumulative voltage effect of the trace at each sub-pixel position is fully reflected. This summation method can more accurately grasp the comprehensive influence of the (x+1)th trace on the second voltage, thereby making the obtained second voltage more accurate and the adjustment of the first voltage more precise. This further optimizes the voltage control of sub-pixels, improves the performance and display effect of the display device, and avoids the generation of dark lines in the display screen.

[0020] In one 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 trace includes:

[0021] A first lookup table is set based on the display device. The first lookup table includes the display grayscale of the first sub-pixel and the first preset value. Each display grayscale of the first sub-pixel corresponds one-to-one with a first preset value.

[0022] 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 trace.

[0023] In this embodiment, the introduction of a first lookup table enables the rapid and accurate acquisition of a first preset value corresponding to the display grayscale of the first sub-pixel, avoiding complex real-time calculations and improving the execution efficiency of the driving method. Simultaneously, the first lookup table can be precisely set and calibrated in advance according to the characteristics and requirements of the display device, allowing the first preset value to better match the actual needs of the first sub-pixel under different display grayscale levels. This enables more precise adjustment of the third voltage during subsequent calculations, further improving the accuracy and adaptability of the third voltage adjustment. This ensures good display quality across various grayscale conditions, enhancing the display effect and stability of the display device.

[0024] In one possible example, the determination of the third voltage based on the second voltage, the first preset value, and the first voltage is performed using the following formula:

[0025] Va = Vb + Vc * Vn, where Va is the third voltage, Vb is the first voltage, and Vc is the first preset value.

[0026] 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 given. Through this formulaic combination, the key parameters obtained in the previous steps are precisely integrated. 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 screen, enabling the display device to better present the expected image effect, and avoiding the generation of dark lines in the display screen of the display device.

[0028] Thirdly, embodiments of this application provide a display device, including a memory and a processor, wherein the memory is used to store computer instructions, and the processor is used to invoke the computer instructions to perform the method provided in the first aspect or any embodiment of the first aspect.

[0046] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a driving method provided in an embodiment of this application. For example...

[0047] Optionally, server 103 can be a standalone server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms. Server 103 can also be implemented through a server cluster composed of multiple sub-servers.

[0048] 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 illustrative purposes only and do not constitute a limitation on the embodiments of this application.

[0049] Please refer to Figure 2 , Figure 2 This is a schematic flowchart of a driving method provided in an embodiment of this application. The method includes the following steps S201-S205, wherein the driving method is applied to the driving circuit of a display device, the display device includes a screen driving module, a system chip module, a display module, and multiple sub-pixels, the screen driving module is connected to the driving circuit, the system chip module, and the display module, the screen driving module is used to transmit a first gamma correction voltage and a second gamma correction voltage, the multiple sub-pixels are all connected to the driving circuit, the multiple 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.

[0050] 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.

[0051] S201: Determine the x-th trace based on at least two sub-driver circuits, including:

[0052] At least two sub-driving circuits include a first sub-driving circuit and a second sub-driving circuit connected to each other;

[0053] The x-th trace is determined based on the first trace of the second sub-driving circuit; or, the x-th trace is determined based on the polarity of traces within at least two sub-driving circuits.

[0054] It should be noted that multiple sub-pixels are arrayed on the driving circuit, which has multiple traces arranged at intervals. The Xth column sub-pixel is connected to the Xth trace, and a parasitic capacitance connects the Xth column sub-pixel to the (X+1)th trace. Furthermore, the first trace of the second sub-driving circuit is the trace on the second sub-driving circuit that is closest to the first sub-driving circuit.

[0055] It should be noted that this trace is a data trace, and it is electrically connected to multiple sub-pixels.

[0056] It should be noted that this method is applied to a normal screen, which is a solid color screen. Under normal circumstances, in this normal screen, the gray levels on adjacent traces do not change instantaneously. For example, the gray levels on adjacent traces do not change instantaneously from gray level 0 to gray level 255.

[0057] Optionally, the polarity of each trace within at least two sub-driving circuits is obtained. The polarities of every two adjacent traces are compared, and two adjacent traces with the same polarity are found within the at least two sub-driving circuits to determine the x-th trace and the (x+1)-th trace. For example, a certain type of display screen includes 6 sub-driving circuits, each responsible for 1920*3 traces, with each sub-driving circuit handling 960 traces. The polarity distribution of the 960 traces handled by each sub-driving circuit is continuous, and the trend of change between every two adjacent traces within each sub-driving circuit is "-+-+", meaning the polarity is reversed. However, the polarity distribution of adjacent traces at the boundary is discontinuous. For example, the polarity of the x-th trace and the (x+1)-th trace are the same, and their trend is "++", meaning the polarity remains unchanged. Since the number of adjacent traces with reversed polarity is much greater than the number of adjacent traces with the same polarity, the overall polarity change of the traces in the drive circuit is "-+-+", while the polarity change of the x-th and x+1-th traces is "++" because their change trends are inconsistent with the overall polarity change trend, that is, the polarity distribution of the x-th and x+1-th traces is discontinuous.

[0058] Optionally, in the driving circuit of the display device, the sub-driving circuits can adopt a distributed layout. The first sub-driving circuit and the second sub-driving circuit are placed on both sides of the panel and connected by signal transmission lines. When determining the x-th trace, the first trace on the side of the second sub-driving circuit closest to the first sub-driving circuit is used. For example, in an ultra-high-definition television panel, the first and second sub-driving circuits are distributed on the left and right sides. This can shorten the signal transmission distance, reduce signal delay and attenuation, improve driving efficiency, and ensure synchronous image display.

[0059] Optionally, for curved display panels, the connection of the sub-driving circuits needs to take into account the curved structure. The first sub-driving circuit is located on the inner side of the curved surface, and the second sub-driving circuit is located on the outer side, with the two connected by a flexible circuit board. In curved automotive displays, this layout ensures the flexibility and reliability of signal transmission, allowing the displayed image to be presented on the curved surface without distortion or delay.

[0060] 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 traces. This ensures that the driving function can be realized normally without affecting the transparency of the panel.

[0061] Optionally, for high refresh rate display panels, such as 240Hz gaming monitors, the sub-drive circuits need to respond quickly. The first and second sub-drive circuits use high-speed drive chips and are connected through high-speed signal transmission lines.

[0062] Optionally, in the foldable display panel of the display device, the first sub-driving circuit and the second sub-driving circuit need to adapt to the folding action. The first sub-driving circuit is placed on one side of the folding axis, and the second sub-driving circuit is placed on the other side, connected by a retractable elastic trace. This ensures the continuity and stability of signal transmission during folding and unfolding, avoids trace breakage or signal interruption due to folding, and guarantees the normal display of the screen.

[0063] Optionally, in the intelligent display panel of the display device, the first sub-driving circuit and the second sub-driving circuit can integrate sensor interfaces. For example, after integrating an ambient light sensor, the display panel can automatically adjust its brightness according to the ambient light intensity. In this case, the corresponding wiring must prioritize the rapid transmission of sensor signals to ensure that the display screen can adjust its brightness in real time according to changes in the environment, thereby improving the user's visual experience.

[0064] In this embodiment, the x-th trace is determined by the first trace of the second sub-driving circuit; or, the x-th trace is determined based on the polarity of traces in at least two sub-driving circuits. This determination method makes the selection of the x-th trace more explicit, accurate and targeted, improving the efficiency and accuracy of determining the x-th trace.

[0065] S202: Determine the second voltage using the voltage correlation values ​​of the first row of sub-pixels in the (x+1)th routing line to the voltage correlation values ​​of the nth row of sub-pixels, including:

[0066] The voltage correlation values ​​of the first row of sub-pixels of the (x+1)th trace are summed to the voltage correlation values ​​of the nth row of sub-pixels to obtain the second voltage.

[0067] Optionally, for display panels requiring rapid response, such as large-screen displays for real-time data display, where the summation operation needs to be completed in a very short time, a summation circuit composed of a high-speed operational amplifier and an analog-to-digital converter can be used. This circuit converts the sub-pixel voltage correlation quantity of the (x+1)th trace into a digital signal, and then performs 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 (FPGA), the second voltage can be obtained within microseconds, ensuring real-time data updates and display.

[0068] Optionally, in low-power display panel designs, such as e-book readers, power consumption must be considered in summation operations. Low-power complementary metal-oxide-semiconductor (CMOS) circuits are employed for summation. Leveraging the characteristic of CMOS circuits to operate normally under low voltage, the voltage-related quantities of the sub-pixel on the (x+1)th trace are added term by term. For example, in the driving circuit of an e-ink screen, by rationally planning the summation circuit, the power consumption of the entire summation process can be reduced to the milliwatt level, extending the e-book's battery life.

[0069] Optionally, for display panels with touch functionality, touch signals may interfere with summation calculations. Adding a filtering stage, such as a low-pass filter, to the summation circuit of the display device can remove high-frequency interference components from the touch signal. For example, in a touch all-in-one machine, when a user touches the screen, the filter can effectively suppress the interference of the touch signal on the summation of sub-pixel voltage correlation quantities, ensuring the accuracy of the second voltage and avoiding display abnormalities caused by the touch signal.

[0070] Optionally, in medical display panels requiring high-precision display, the summation of voltage-related quantities of sub-pixels needs to achieve high accuracy. This is achieved using high-precision analog-to-digital converters and digital signal processors (DSPs). For example, a 16-bit or even higher precision analog-to-digital converter can be used to sample the voltage-related quantities of sub-pixels, and then the digital signal processor of the display device can perform high-precision floating-point calculations to ensure that the calculation accuracy of the second voltage reaches the microvolt level. This makes the display of medical images more accurate and clearer, contributing to precise diagnosis.

[0071] Optionally, when the display device is applied to an intelligent display system, the summation operation can be optimized by combining artificial intelligence algorithms. For example, by using machine learning algorithms to predict the changing trend of the sub-pixel voltage related quantities of the (x+1)th trace, the parameters of the summation algorithm can be adjusted in advance. When displaying dynamic content, such as video playback, the summation process can be 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 drive.

[0072] Optionally, for multi-panel splicing display systems, such as large video walls, the summation calculation needs to consider the coordination of multiple panels. The voltage correlation of the sub-pixels on the (x+1)th trace of each panel is summed separately, and then a comprehensive processing is performed to obtain the second voltage of the entire video wall. For example, the summation results of each panel are transmitted to the central controller via network communication. The central controller performs unified comprehensive calculations to ensure uniform brightness and consistent color of the entire video wall display, achieving a seamless splicing display effect.

[0073] In this embodiment, the second voltage is determined by summing the voltage correlation values ​​of the first row of sub-pixels of the (x+1)th trace to the voltage correlation values ​​of the nth row of sub-pixels. This allows for more precise control of the sub-pixel voltage, improving the uniformity and accuracy of the display effect, avoiding display abnormalities caused by unreasonable local voltages, and preventing dark lines from appearing in the display screen.

[0074] The voltage correlation values ​​of the first row sub-pixels of the (x+1)th trace to the voltage correlation values ​​of the nth row sub-pixels are summed to obtain the second voltage, including:

[0075] Un=[U n+ -U k +(U n- -U j )] / 2, Un is the voltage-related quantity of the nth row sub-pixel of the (x+1)th trace, U n+ U represents the positive polarity voltage of the sub-pixel in the nth row corresponding to the (x+1)th trace. n- U is the negative polarity voltage of the sub-pixel in the nth row corresponding to the (x+1)th trace. k U is the first gamma correction voltage. j This is the second gamma correction voltage.

[0076] Optionally, in high-contrast display panels, the positive and negative polarity voltages of sub-pixels differ significantly. When calculating the voltage-related quantities of the nth row of sub-pixels, a high-precision voltmeter is used to measure the positive and negative polarity voltages separately, and then the values ​​are substituted into the formula for calculation. Simultaneously, the values ​​of the first and second gamma correction voltages are precisely controlled to ensure the accuracy of the calculated Un.

[0077] Optionally, for display panels of display devices that require rapid screen switching, such as virtual reality displays, the calculation Un needs to be completed quickly. High-speed computing circuits, such as high-speed operational amplifiers and fast analog-to-digital converters, are used to perform rapid sampling and calculation to ensure rapid screen switching, reduce latency, and improve the user's immersion.

[0078] Optionally, for high color gamut display panels, such as quantum dot displays, the chromaticity differences between sub-pixels are significant. When calculating Un, the influence of chromaticity on voltage must be considered. A precise color calibration technique is used to establish the correspondence between chromaticity and voltage. For example, during the production process of a quantum dot display panel, each sub-pixel undergoes color calibration to obtain its positive and negative polarity voltage values ​​at different chromaticities. When calculating Un, based on the actual color requirements of the display, the positive and negative polarity voltages of the corresponding nth row of sub-pixels are obtained from the calibration data and substituted into the formula to ensure the accuracy and richness of the displayed colors.

[0079] Optionally, in the intelligent display system of the display device, the values ​​of the two gamma voltages can be dynamically adjusted to adapt to different display requirements. For example, when displaying a high-brightness image, the values ​​of the two gamma voltages are appropriately increased to improve the calculation result of Un, allowing the sub-pixels to obtain a higher driving voltage and improving brightness performance. Conversely, when displaying a low-brightness image, the values ​​of the two gamma voltages are decreased to reduce power consumption. Intelligent display control is achieved by monitoring the display content in real time through intelligent algorithms and dynamically adjusting the gamma voltages to optimize the calculation of Un.

[0080] In this embodiment, by considering the effects of the positive polarity voltage, negative polarity voltage, and gamma voltage of the sub-pixel, this formulaic calculation makes the determination process of the voltage correlation quantity of the nth row of sub-pixels more scientific and accurate, and enables a more detailed analysis of the voltage correlation quantity of each sub-pixel, thereby improving the accuracy of obtaining the voltage correlation quantity of the nth row of sub-pixels.

[0081] The second voltage is obtained by summing the voltage correlation values ​​of the first row sub-pixels of the (x+1)th trace to the voltage correlation values ​​of the nth row sub-pixels, using the following formula:

[0082] Vn = U1 + U2 + ... + Un, where 1 ≤ n ≤ i, Vn is the second voltage, and i is the total number of rows in the display module.

[0083] Optionally, for display panels in display devices requiring rapid response, such as esports monitors, the summation calculation needs to be completed in a very short time. This requires the use of high-speed processors and dedicated mathematical processing chips. For example, the parallel computing capabilities of the graphics processing unit (GPU) can be used to quickly sum sub-pixel voltage-related quantities. The GPU's massive parallel processing units can complete the summation of large amounts of data within milliseconds, ensuring timely updates to the second voltage and enabling the game screen to respond quickly to player actions.

[0084] Optionally, for display panels in touch-enabled devices, touch signals may interfere with summation calculations. Adding a filtering stage, such as a bandpass filter, to the summation circuit can remove the frequency components of the touch signal. For example, in touchscreen phones, when a user touches the screen, the filter can effectively suppress interference from the touch signal on the summation of sub-pixel voltage correlation quantities, ensuring the accuracy of the second voltage, avoiding display abnormalities caused by touch signals, and improving the user experience.

[0085] Optionally, in intelligent display systems, the summation operation can be optimized by combining it with machine learning algorithms. By training a 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 calculation efficiency and accuracy of the second voltage, thereby achieving a more intelligent and efficient display drive.

[0086] In this embodiment, the sum of voltage-related quantities of sub-pixels corresponding to different rows of the (x+1)th trace is considered. By using this formula calculation method, the voltage situation of the (x+1)th trace can be analyzed more comprehensively. By summing the voltage-related quantities of sub-pixels in multiple rows, the cumulative voltage effect of the trace at each sub-pixel position is fully reflected. This summation method can more accurately grasp the comprehensive influence of the (x+1)th trace on the second voltage, thereby making the obtained second voltage more accurate and the adjustment of the first voltage more precise. This further optimizes the voltage control of sub-pixels, improves the performance and display effect of the display device, and avoids the generation of dark lines in the display screen.

[0087] S203: Determine the first preset value based on the display grayscale of the first sub-pixel in the nth row corresponding to the xth trace.

[0088] In this embodiment, the introduction of a first lookup table enables the rapid and accurate acquisition of a first preset value corresponding to the display grayscale of the first sub-pixel, avoiding complex real-time calculations and improving the execution efficiency of the driving method. Simultaneously, the first lookup table can be precisely set and calibrated in advance according to the characteristics and requirements of the display device, allowing the first preset value to better match the actual needs of the first sub-pixel under different display grayscale levels. This enables more precise adjustment of the third voltage during subsequent calculations, further improving the accuracy and adaptability of the third voltage adjustment. This ensures good display quality across various grayscale conditions, enhancing the display effect and stability of the display device.

[0089] The first preset value is determined based on the display grayscale of the first sub-pixel in the nth row corresponding to the xth trace, including:

[0090] A first lookup table is set based on the display device. The first lookup table includes the display grayscale of the first sub-pixel and a first preset value. The display grayscale of each first sub-pixel corresponds one-to-one with a first preset value.

[0091] 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 trace.

[0092] Optionally, establishing a first lookup table is a crucial step in the display device manufacturing process. Based on the characteristics and design requirements of the display panel, the relationship between the display grayscale of each sub-pixel and the required first preset value is precisely measured. For example, using specialized calibration instruments, the electrical and optical characteristics of sub-pixels at different grayscale levels are tested to obtain the corresponding first preset values. This data is stored in the display panel's drive circuitry, ensuring that in actual use, the first preset value can be quickly and accurately retrieved from the lookup table based on the sub-pixel's display grayscale, achieving precise drive control.

[0093] Optionally, for display panels of high refresh rate devices, such as 240Hz gaming monitors, the read speed of the first lookup table needs to be very fast. This requires using high-speed memory to store the first lookup table and optimizing the lookup algorithm. For example, using static random access memory (SRAM) to store the first lookup table, with a read speed in the nanosecond range, ensures that the first preset value can be obtained promptly at high refresh rates, guaranteeing rapid updates to the display and providing players with a smoother visual experience in games.

[0094] Optionally, for display panels of display devices requiring high-precision grayscale control, such as medical imaging displays, the first lookup table needs to have high-precision grayscale division. For example, the grayscale can be divided into more levels, and precise brightness and color measurements can be performed on each level to obtain the corresponding first preset value. This ensures more accurate grayscale display of medical images and improves diagnostic accuracy.

[0095] S204: Determine the third voltage based on the second voltage, the first preset value, and the first voltage.

[0096] The third voltage is determined based on the second voltage, the first preset value, and the first voltage, using the following formula:

[0097] Va = Vb + Vc * Vn, where Va is the third voltage, Vb is the first voltage, and Vc is the first preset value.

[0098] Optionally, in high-resolution display panels, calculating the third voltage Va requires processing a large amount of data. A parallel computing architecture is employed, with multiple computing units simultaneously calculating Va for sub-pixels in different regions. For example, in an 8K display panel, multiple computing regions are divided, each equipped with a computing unit, and the Va values ​​from each region are finally aggregated. This significantly improves the calculation speed, meeting the real-time requirements of high-resolution display panels and ensuring smooth image display.

[0099] Optionally, for display panels in devices requiring rapid response, such as esports monitors, the calculation of the third voltage needs to be completed in an extremely short time. This is achieved using high-speed processors and dedicated mathematical processing chips. For example, the parallel computing capabilities of a graphics processing unit (GPU) can be used to quickly calculate the formula for the third voltage. The GPU's massive parallel processing units can complete the calculation of large amounts of data within milliseconds, ensuring timely updates to the third voltage and enabling the game screen to respond quickly to player actions.

[0100] Optionally, for display panels of touch-enabled display devices, touch signals may interfere with the calculation of the third voltage. Therefore, a filtering stage, such as a bandpass filter, can be added to the calculation circuit to filter out the frequency components of the touch signal. For example, in touchscreen phones, 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 third voltage calculation, avoiding display abnormalities caused by touch signals, and improving the user experience.

[0101] 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 given. Through this formulaic combination, the key parameters obtained in the previous steps are precisely integrated. 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 screen, enabling the display device to better present the expected image effect, and avoiding the generation of dark lines in the display screen of the display device.

[0102] S205: Control the display module to transmit the third voltage to the first sub-pixel.

[0103] In this embodiment, the composition and connection relationship of each module of the display device are clearly defined. The x-th trace is determined based on at least two sub-driving circuits, and the polarity of the sub-pixel corresponding to the x-th trace is the same as that of the sub-pixel corresponding to the (x+1)-th trace. A second voltage is determined by the voltage correlation between the first row of sub-pixels of the (x+1)-th trace and the voltage correlation between the n-th row of sub-pixels. A 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 trace. 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, thereby compensating for the first voltage of the first sub-pixel, enhancing the display brightness of the first sub-pixel, avoiding dark lines in the display screen, improving the quality of the display screen, and making the display effect more accurate.
