Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to a display method and display device. Background Technology

[0002] The development of display technology has led to the widespread application of display panels in various electronic devices. Liquid Crystal Displays (LCDs) are more energy-efficient and lighter than traditional cathode ray tubes (CRTs) and plasma TVs, and are known as cold displays or environmentally friendly displays. Currently, they are developing towards higher resolution, higher image quality, and larger screen sizes. Because liquid crystals have a capacitive charging and discharging structure, DC driving can easily generate residual charge, resulting in image retention. Therefore, AC driving is required to achieve polarity reversal, using the Common Voltage (VCOM) as a reference to distinguish between positive and negative polarities. However, VCOM is susceptible to interference from data lines and can be pulled off course when the gate is turned on or when the data voltage changes. If the standard voltage is not restored in time, it will cause abnormal charging of the pixel electrodes, leading to display errors and affecting image quality. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0019] The display device provided in this application can have various implementation forms, such as a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc.

[0020] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0021] In the following embodiments, a television set is used as an example to illustrate the method of this application. When the television set executes the display method provided in this embodiment, the display method may be executed by the television set's display driver chip.

[0022] This application provides a display method, such as... Figure 1 As shown, the display method may include S11-S15.

[0023] S11. Obtain the driving voltage difference between at least one column of actual pixels in the Nth row and the (N-1th row) of the frame image of the current frame; where N is an integer greater than or equal to 1.

[0024] S12. Based on the driving voltage difference, filter the actual pixels in the Nth row to determine at least one target pixel; wherein, the target pixel includes any one of the actual pixels.

[0025] In some examples, when filtering actual pixels in the Nth row based on the driving voltage difference to determine at least one target pixel, the crosstalk value can be determined first based on the driving voltage difference. When the crosstalk value is greater than the crosstalk threshold, the actual pixels in the Nth row are filtered, and adjacent actual pixels in the Nth row whose driving voltage difference is continuously greater than a preset voltage difference are taken as target pixels. It can be seen that the display method provided by the embodiments of this disclosure first obtains the driving voltage difference between adjacent rows of pixels, but does not directly filter all pixels with continuous voltage difference abnormalities globally. Instead, it first evaluates the overall crosstalk value based on the driving voltage difference. Only when the crosstalk value is greater than the crosstalk threshold and it is determined that there is obvious inter-row crosstalk interference, are the adjacent actual pixels in the Nth row filtered, and adjacent pixels whose driving voltage difference is continuously greater than a preset voltage difference are determined as target crosstalk pixels. Then, the fusion compensation voltage is calculated by combining the specified compensation voltage, the driving voltage difference, and the original driving voltage, and finally the target pixel is displayed with voltage compensation and pixel value correction. This approach effectively distinguishes between normal image quality fluctuations and genuine interline crosstalk interference, avoiding misjudging normal brightness changes as crosstalk and overcompensating. Through a continuous adjacent pixel filtering mechanism, it accurately identifies horizontal continuous strip crosstalk caused by LCD row-column coupling and eliminates isolated single-point noise interference. At the same time, it only performs subsequent filtering and compensation calculations when crosstalk exceeds the limit, significantly reducing the real-time computation load of the display driver and adapting to high-resolution, high-refresh-rate display driver slicing processing scenarios. The compensation process integrates the original driving voltage and voltage difference information, and the compensation intensity is adaptive, smooth, and non-abrupt, effectively suppressing interline crosstalk distortion, optimizing the uniformity of image brightness transition, and improving the natural light perception of the image and the realism of the display image quality under high dynamic range.

[0026] In some examples, the crosstalk value is determined based on the driving voltage difference, including summing the driving voltage differences to obtain a total driving voltage difference, and using the total driving voltage difference as the crosstalk value.

[0027] In some examples, in a television display screen, pixel electrodes exhibit two driving polarities relative to the common electrode VCOM: positive when the pixel driving voltage is higher than VCOM and negative when it is lower. During charging and driving, pixels with positive and negative polarities exert coupling interference and potential pulling effects on the common electrode VCOM in opposite directions, resulting in either superposition or cancellation of their effects on VCOM fluctuations. Therefore, when calculating the sum of driving voltage differences between adjacent pixels to assess crosstalk, a simple algebraic addition is insufficient. Instead, polarity discrimination must be performed in conjunction with the actual polarity reversal arrangement used in the LCD panel: for adjacent pixels with the same polarity, their voltage differences have the same direction of coupling interference to VCOM, so the corresponding voltage differences are accumulated; for adjacent pixels with different polarities, their voltage differences have opposite directions of coupling interference to VCOM, so the corresponding voltage differences are subtracted. This weighted calculation method, considering polarity differences, yields a final sum of driving voltage differences that more accurately reflects the fluctuation level of VCOM under actual panel driving, thereby more accurately assessing crosstalk risk and improving the reliability and accuracy of crosstalk judgment. In some examples, after calculating the driving voltage difference between at least one actual pixel in the Nth row and its adjacent pixels, all actual pixels in that row are traversed, and one or more segments of pixels whose driving voltage difference is continuously greater than a preset voltage difference threshold are selected. These actual pixels are recorded as target pixels, such as: For the Nth row of the current frame image, calculate the driving voltage difference between adjacent pixels pixel by pixel; A differential voltage threshold (such as a preset differential voltage) is set in advance to judge the risk of crosstalk. When the driving voltage difference exceeds the preset differential voltage, it is considered that the position is prone to crosstalk due to excessive voltage jump. Traverse all pixels in the Nth row and find the pixel region where the driving voltage difference is continuously greater than the preset voltage difference; These pixels that meet the "continuously exceeding the threshold" condition are identified as target pixels and used as the objects for subsequent crosstalk suppression, voltage compensation, or image quality optimization.

[0028] In some examples, the display method provided in this disclosure uses a sliding window algorithm to identify crosstalk regions: a window of a set size slides row by row in the frame image of the current frame, calculating the exponential energy of the pixel voltage difference (ripple) within the current window, i.e., the sum of the squares of the voltage differences of each pixel; if the energy value of the exponential energy is greater than a preset judgment threshold (such as a preset voltage difference), the pixels in the current window are initially judged as pixels with crosstalk risk to be compensated. Considering that a single window may contain both high-frequency crosstalk components and low-frequency normal fluctuations, in order to accurately locate the high-frequency region corresponding to crosstalk, the window continues to slide along the row direction for continuous judgment; when the energy values ​​of n consecutive sliding windows are all greater than the preset voltage difference, the starting position (start) of the high-frequency crosstalk region is marked; when sliding to a certain window, its energy value is less than the preset threshold, the ending position (end) of the high-frequency crosstalk region is immediately marked, thereby completing the accurate division of the high-frequency crosstalk region. Then, the actual pixels between the starting position (start) and the ending position (end) in the pixel row are taken as target pixels.

[0029] S13. Based on the specified compensation voltage value, the driving voltage difference, and the current driving voltage value of at least one target pixel, determine the fusion compensation voltage value of at least one target pixel.

[0030] In some examples, when determining the fusion compensation voltage value of at least one target pixel based on a specified compensation voltage value, a driving voltage difference, and the current driving voltage value of at least one target pixel, the theoretical voltage compensation value of at least one target pixel can be determined based on a preset compensation voltage value, a first compensation voltage value, a second compensation voltage value, a driving voltage difference, and the current driving voltage value of at least one target pixel; the compensation coefficient of at least one target pixel can be determined based on the driving voltage difference and the theoretical voltage compensation value of at least one target pixel; the actual voltage compensation value of at least one target pixel can be determined based on the theoretical voltage compensation value and the compensation coefficient of at least one target pixel; and the fusion compensation voltage value of at least one target pixel can be determined based on the current driving voltage value and the actual voltage compensation value of at least one target pixel.

[0031] In some examples, the preset compensation voltage value can be 0, the first compensation voltage value can be the maximum compensation voltage value, and the second compensation voltage value can be the minimum compensation voltage value. Specifically, users can set the preset compensation voltage value, the first compensation voltage value, and the second compensation voltage value based on actual conditions, and this disclosure does not limit the settings.

[0032] In some examples, the first compensation voltage value is greater than the preset compensation voltage value, and the preset compensation voltage value is greater than the second compensation voltage value.

[0033] In some examples, when determining the fusion compensation voltage value of at least one target pixel based on a specified compensation voltage value, a driving voltage difference, and the current driving voltage value of at least one target pixel, the specified compensation voltage value, the driving voltage difference, and the current driving voltage value of at least one target pixel can be input into the compensation model for calculation to determine the fusion compensation voltage value of at least one target pixel. The training process of the compensation model includes: Acquire first training sample data and a first labeling result of the first training sample data. The first training sample data includes at least one set of historical data, and the first labeling result includes the fusion compensation voltage value of at least one target pixel in each set of historical data. Each set of historical data includes a preset compensation voltage value, a first compensation voltage value, a second compensation voltage value, a driving voltage difference, and the current driving voltage value of at least one target pixel.

[0034] The first training sample data is input into the first neural network model for learning, and the first prediction result of the first neural network model on the first training sample data is obtained.

[0035] Based on the first prediction result and the first labeling result, the network parameters of the first neural network model are adjusted until the first neural network model converges, and the converged first neural network model is used as the compensation model.

[0036] S14. Based on the fusion compensation voltage value of at least one target pixel, determine the compensation pixel value of at least one target pixel; In some examples, when determining the compensation pixel value of at least one target pixel based on the fusion compensation voltage value of at least one target pixel, a preset relationship table can be consulted based on the fusion compensation voltage value of the target pixel to determine the theoretical pixel value corresponding to the fusion compensation voltage value; the theoretical pixel value is then used as the compensation pixel value of the target pixel.

[0037] In some examples, a preset relationship table is pre-stored in the television's memory. When it is necessary to determine the compensation pixel value, the television's display driver chip queries the preset relationship table in memory based on the fusion compensation voltage value of the target pixel, thereby determining the theoretical pixel value corresponding to the fusion compensation voltage value; the theoretical pixel value is then used as the compensation pixel value for the target pixel. The process of establishing the preset relationship table includes: Excessive voltage difference between adjacent data lines can cause fluctuations in the common electrode voltage VCOM, leading to abnormal pixel electrode charging and crosstalk interference. Therefore, determining whether crosstalk will occur in a particular row of an image hinges on accurately calculating the voltage difference between adjacent rows. This calculation must be based on the known relationship between pixel values ​​and pixel voltages. For example, a test image with pure grayscale values ​​increasing from 0 to 255 is input to the LCD monitor, and a full-screen solid color image is output for each grayscale value. A high-precision oscilloscope is used to measure the actual output voltage of the data lines at each grayscale value in real time, obtaining a set of measured data corresponding to the pixel grayscale values ​​and data line driving voltages. Based on this set of measured results, fitting or mapping is performed and stored to establish a preset relationship table between pixel grayscale values ​​and pixel driving voltages, providing a basis for subsequent calculation of voltage differences between adjacent rows and assessment of crosstalk risk.

[0038] In some examples, when determining the compensated pixel value of at least one target pixel based on the fusion compensation voltage value of at least one target pixel, a calculation operation is performed for each target pixel; the calculation operation includes: The calculated target pixel fusion compensation voltage value is used as the input variable and substituted into a preset calculation function. The corresponding compensation pixel value is obtained through function mapping. The calculation function adopts the form of a univariate function y = f(x), where the independent variable x represents the input fusion compensation voltage value and the dependent variable y represents the output compensation pixel value after function transformation. This function realizes a precise mapping from the voltage domain to the pixel value domain, providing data basis for subsequent pixel display and drive control.

[0039] S15. Display the target pixels in the frame image of the current frame according to the compensation pixel value corresponding to at least one target pixel.

[0040] As described above, the display method provided in this embodiment of the present disclosure accurately locates areas with drastic data voltage fluctuations by obtaining the driving voltage difference between at least one column of actual pixels in the Nth row and the (N-1th row) of the current frame image; then, based on the driving voltage difference, it filters out target pixels that continuously exceed a preset voltage difference and are prone to VCOM fluctuations; subsequently, it calculates a fusion compensation voltage value that adapts to the interference level of the pixel by combining a specified compensation voltage value, the driving voltage difference, and the current driving voltage of the target pixel, and converts it into a corresponding compensation pixel value; finally, the controller corrects the display of the target pixel according to the compensation pixel value, thereby suppressing VCOM bias caused by excessive data voltage difference from the source, avoiding abnormal pixel electrode charging, and thus improving display errors and enhancing image quality.

[0041] In some feasible examples, the specified compensation voltage value includes a preset compensation voltage value, a first compensation voltage value, and a second compensation voltage value; combined with Figure 1,like Figure 2 As shown, the above S13 can be specifically implemented through the following S130-S133.

[0042] S130. Based on the preset compensation voltage value, the first compensation voltage value, the second compensation voltage value, the driving voltage difference, and the current driving voltage value of at least one target pixel, determine the theoretical voltage compensation value of at least one target pixel.

[0043] S131. Based on the driving voltage difference and the theoretical voltage compensation value of at least one target pixel, determine the compensation coefficient of at least one target pixel; In some examples, when determining the compensation coefficient of at least one target pixel based on the driving voltage difference and the theoretical voltage compensation value of at least one target pixel, the compensation coefficient of at least one target pixel can be determined based on the sum of the driving voltage differences and the sum of the theoretical voltage compensation values ​​of at least one target pixel. For example, the compensation coefficient is equal to the ratio of the sum of the driving voltage differences to the sum of the theoretical voltage compensation values ​​of at least one target pixel.

[0044] Alternatively, the driving voltage difference and the theoretical voltage compensation value of at least one target pixel can be input into the coefficient model for calculation to obtain the compensation coefficient of at least one target pixel; wherein, the training process of the coefficient model includes: Obtain the second training sample data and the second labeling result of the second training sample data; wherein, the second training sample data includes: the driving voltage difference corresponding to the historical frame image and the theoretical voltage compensation value of at least one target pixel, and the second labeling result includes the driving voltage difference corresponding to the historical frame image and the theoretical voltage compensation value of at least one target pixel, and the corresponding compensation coefficient.

[0045] The second training sample data is input into the second neural network model for learning, and the second prediction result of the second neural network model on the second training sample data is obtained.

[0046] Based on the second prediction result and the second labeling result, the network parameters of the second neural network model are adjusted until the second neural network model converges, and the converged second neural network model is used as the coefficient model.

[0047] S132. Based on the theoretical voltage compensation value and compensation coefficient of at least one target pixel, determine the actual voltage compensation value of at least one target pixel. In some examples, when determining the actual voltage compensation value of at least one target pixel based on the theoretical voltage compensation value and compensation coefficient of at least one target pixel, the actual voltage compensation value of at least one target pixel can be determined based on the product of the theoretical voltage compensation value and compensation coefficient of at least one target pixel.

[0048] In some examples, when determining the actual voltage compensation value of at least one target pixel based on its theoretical voltage compensation value and compensation coefficient, at least two driving voltage difference intervals can be preset (e.g., low crosstalk interval: driving voltage difference ≤ preset low threshold; high crosstalk interval: driving voltage difference > preset low threshold), and a corresponding compensation coefficient can be assigned to each interval. (Low crosstalk range) Use a value of 0.3 to 0.5, which represents the high crosstalk range. (Take a value of 0.6 to 0.9, which can be adjusted according to the actual characteristics of the panel); obtain the theoretical voltage compensation value of at least one target pixel. And the corresponding driving voltage difference, determine the preset interval to which the driving voltage difference belongs; and the compensation coefficient corresponding to the interval. Compared with theoretical voltage compensation value Multiplying these values ​​yields the preliminary actual voltage compensation value: Introducing a polarity correction factor (positive polarity pixel) =1, negative polarity pixel =-1), the initial actual voltage compensation value is corrected, and the final actual voltage compensation value is obtained: After completing the calculation, for Clamping is performed to ensure that the voltage does not exceed the minimum and maximum compensation voltage range, thus avoiding interference with normal pixel driving and display. This allows for dynamic adjustment of the compensation intensity based on crosstalk strength (driving voltage difference range) and pixel polarity, resulting in higher compensation accuracy. It effectively solves compensation deviations in different crosstalk scenarios, and is particularly suitable for the complex crosstalk suppression needs of large-size, high-definition LCDs.

[0049] S133. Based on the current driving voltage value and the actual voltage compensation value of at least one target pixel, determine the fusion compensation voltage value of at least one target pixel.

[0050] In some examples, when determining the fusion compensation voltage value of at least one target pixel based on its current driving voltage value and actual voltage compensation value, the following steps can be taken: First, obtain the target pixel's current driving voltage V_in (i.e., the original driving voltage before compensation, consistent with the driving voltage difference and polarity determination results). Then, obtain the corresponding actual voltage compensation value V_comp. Next, calculate the fusion compensation voltage value using the linear fusion formula: V_fusion = V_in + V_comp. Finally, perform a threshold check on the calculated V_fusion to ensure it falls within the allowable voltage range for the LCD panel driver. If it exceeds the range, use the corresponding threshold to avoid pixel display distortion or hardware damage due to abnormal voltage. This allows for rapid fusion of the current driving voltage and the compensation voltage, effectively offsetting the effects of VCOM offset and ensuring pixel display stability. This method is suitable for low to medium resolution scenarios with relatively mild crosstalk.

[0051] In some examples, when determining the fusion compensation voltage value of at least one target pixel based on its current driving voltage value and actual voltage compensation value, the current driving voltage V_in and actual voltage compensation value V_comp of the target pixel can be obtained, along with the driving voltage difference (i.e., the crosstalk intensity characterization value) corresponding to that pixel. A weighting coefficient w (0≤w≤1) is set, which is positively correlated with the crosstalk intensity: the higher the crosstalk intensity (the larger the driving voltage difference), the closer w is to 1 (the higher the compensation voltage weight); the lower the crosstalk intensity, the closer w is to 0 (the higher the current driving voltage weight). The weighting coefficient can be preset or dynamically adjusted according to the panel characteristics. The fusion compensation voltage value is calculated using the weighted fusion formula: V_fusion = (1 - w) × V_in + w × V_comp. V_fusion is then corrected for polarity adaptation and subjected to threshold clamping to ensure it meets the driving requirements of the LCD panel, ultimately outputting a stable fusion compensation voltage. This avoids over-compensation or under-compensation, making it particularly suitable for high-resolution, large-size LCD panels. It can better adapt to crosstalk differences in different areas, further improving the uniformity and stability of the displayed image.

[0052] In some examples, threshold clamping refers to the operation of limiting and correcting voltage values ​​that exceed the threshold during the calculation of actual voltage compensation values ​​and fusion compensation voltage values, in order to prevent the calculated voltage values ​​from exceeding the safe range allowed by the LCD panel driver (i.e., the preset minimum voltage threshold and maximum voltage threshold). Essentially, it is to ensure the stable operation of the display device and avoid hardware damage and display abnormalities.

[0053] For example, taking the premise that the LCD panel has a defined safe driving voltage range (i.e., threshold), exceeding this range will lead to abnormal pixel charging, display distortion, or even damage to the panel driving module, the threshold clamping process will be explained: Processing logic: When the calculated actual voltage compensation value ( When the fusion compensation voltage value (V_fusion) exceeds the preset minimum / maximum voltage threshold, the voltage value is forcibly adjusted to the corresponding threshold (if it exceeds the maximum threshold, the maximum threshold is used; if it is below the minimum threshold, the minimum threshold is used). If it does not exceed the threshold, the original calculated value remains unchanged. Thus, it can avoid abnormal pixel electrode charging and increased VCOM offset due to excessively high / low compensation voltage, ensuring that the compensated voltage meets the driving requirements of the LCD panel, guaranteeing display stability, and protecting the panel hardware from damage. This aligns with the core requirements of crosstalk suppression and accurate pixel charging mentioned above.

[0054] As described above, the display method provided in this embodiment, after identifying target pixels with crosstalk risk, calculates the theoretical voltage compensation value for each target pixel based on a preset compensation voltage value, a first compensation voltage value, and a second compensation voltage value, combined with the driving voltage difference and the current driving voltage value of the target pixel. Then, it determines an appropriate compensation coefficient based on the driving voltage difference and the theoretical voltage compensation value, dynamically weights the theoretical voltage compensation value, and obtains an actual voltage compensation value that better reflects the actual interference level. Finally, it fuses the current driving voltage value and the actual voltage compensation value to obtain the final fused compensation voltage value, which is then converted into a compensation pixel value to correct the display of the target pixel. This effectively counteracts the pulling interference of the data voltage difference on the VCOM, suppresses VCOM fluctuations, ensures normal charging of the pixel electrodes, thereby improving display abnormalities and enhancing the image display effect.

[0055] In some feasible examples, combining Figure 2 ,like Figure 3 As shown, the above S130 can be implemented by the following S1300.

[0056] S1300: Based on multiple factors including a preset compensation voltage value, a first compensation voltage value, a second compensation voltage value, a driving voltage difference, a current driving voltage value of at least one target pixel, and the polarity of the current driving voltage, determine a theoretical voltage compensation value for at least one target pixel.

[0057] In some examples, the current driving voltage of a pixel corresponds to a current driving voltage value.

[0058] For example, taking the current driving voltage value of any target pixel as 100, the preset compensation voltage value as 0, the first compensation voltage value as +155, and the second compensation voltage value as -155 as an example, the method of determining the theoretical voltage compensation value of at least one target pixel based on multiple factors including the preset compensation voltage value, the first compensation voltage value, the second compensation voltage value, the driving voltage difference, the current driving voltage value of at least one target pixel, and the polarity of the current driving voltage is explained.

[0059] When the sum of the driving voltage differences is less than 0 and the polarity of the current driving voltage of the target pixel is positive, the theoretical voltage compensation value of the target pixel is determined to be the difference between the first compensation voltage value and the current driving voltage value, i.e., 155-100=55; therefore, the theoretical voltage compensation value of the target pixel is 55.

[0060] Alternatively, when the sum of the driving voltage differences is greater than 0 and the polarity of the current driving voltage of the target pixel is positive, the theoretical voltage compensation value of the target pixel is determined to be the difference between the preset compensation voltage value and the current driving voltage value, i.e., 0-155=-155; therefore, the theoretical voltage compensation value of the target pixel is -155.

[0061] For example, taking the current driving voltage value of any target pixel as -100, the preset compensation voltage value as 0, the first compensation voltage value as +155, and the second compensation voltage value as -155, we will explain how to determine the theoretical voltage compensation value of at least one target pixel based on multiple factors including the preset compensation voltage value, the first compensation voltage value, the second compensation voltage value, the driving voltage difference, the current driving voltage value of at least one target pixel, and the polarity of the current driving voltage.

[0062] When the sum of the driving voltage differences is less than 0 and the polarity of the current driving voltage of the target pixel is negative, the theoretical voltage compensation value of the target pixel is determined to be the difference between the preset compensation voltage value and the current driving voltage value, i.e., 0 - (-100) = 100; therefore, the theoretical voltage compensation value of the target pixel is 100.

[0063] Alternatively, when the sum of the driving voltage differences is greater than 0 and the polarity of the current driving voltage of the target pixel is negative, the theoretical voltage compensation value of the target pixel is determined to be the difference between the second compensation voltage value and the current driving voltage value, i.e. (-155) - (-100) = -55; therefore, the power voltage compensation value of the target pixel is -55.

[0064] As described above, the display method provided in this embodiment calculates the theoretical voltage compensation value by combining multiple parameters, such as the preset compensation voltage value, the first compensation voltage value, the second compensation voltage value, the driving voltage difference, and the current driving voltage value of the target pixel, so that the obtained theoretical voltage compensation value can match the true direction and amplitude of VCOM interference under different polarities. Then, through the step-by-step calculation of subsequent compensation coefficients, actual voltage compensation values, and fused compensation voltage values, accurate compensation for pixels in the crosstalk region is achieved, effectively offsetting the bias effect of data voltage jumps on VCOM under different polarities, ensuring accurate and stable pixel electrode charging, thereby solving the display abnormality problem caused by VCOM fluctuations and improving the display effect in high-resolution and high-quality scenarios.

When the sum of the driving voltage differences is less than the preset compensation voltage value, and the polarity of the current driving voltage of the target pixel is positive, the theoretical voltage compensation value of the target pixel is determined to be the difference between the first compensation voltage value and the current driving voltage value.

[0067] As can be seen from the above, the display method provided in this embodiment of the present disclosure, when the sum of the driving voltage differences is less than the preset compensation voltage value and the current driving voltage of the target pixel is positive, determines the theoretical voltage compensation value of the target pixel as the difference between the first compensation voltage value and the current driving voltage value, so as to accurately match the actual offset direction and offset amplitude of VCOM under the polarity and voltage difference conditions, and provide a compensation benchmark that conforms to the real driving characteristics for subsequent calculation of compensation coefficient, actual voltage compensation value and fusion compensation voltage value, thereby offsetting the pulling effect of data voltage on VCOM from the source, ensuring accurate charging of pixel electrodes, thereby improving the display abnormality problem caused by VCOM fluctuation and improving the display quality of the picture.

[0068] In some feasible examples, combining Figure 4 ,like Figure 5 As shown, the above S1300 can be specifically implemented through the following S1300-2.

[0070] As described above, the display method provided in this embodiment determines the theoretical voltage compensation value of the target pixel as the difference between the preset compensation voltage value and the current driving voltage value when the sum of the driving voltage differences is greater than the preset compensation voltage value and the polarity of the current driving voltage of the target pixel is positive. When the sum of the driving voltage differences is greater than the preset compensation voltage value, the interference trend of VCOM can be offset by this compensation value. Combined with the pulling characteristics of positive polarity, using the difference between the preset compensation voltage value and the current driving voltage value as the theoretical compensation benchmark can accurately adapt to the interference pattern in this scenario, providing a scientific basis for the subsequent calculation of compensation coefficients, actual voltage compensation values, and fusion compensation voltage values. Through this targeted theoretical compensation value calculation, the pulling effect of data voltage jumps on VCOM in this specific scenario can be effectively offset, correcting the problem of abnormal pixel electrode charging, thereby solving the display errors and image quality degradation caused by VCOM fluctuations in the background technology, adapting to the development needs of high-resolution, high-quality LCDs, and improving the display quality and stability of the display panel.

When the sum of the driving voltage differences is less than the preset compensation voltage value, and the polarity of the current driving voltage of the target pixel is negative, the theoretical voltage compensation value of the target pixel is determined to be the difference between the preset compensation voltage value and the current driving voltage value.

[0073] As can be seen from the above, the display method provided in this embodiment indicates that when the sum of the driving voltage differences is less than the preset compensation voltage value, it means that the voltage jump of the adjacent pixel pulls on VCOM in the same direction as the interference direction of the negative polarity pixel. At this time, by using the "difference between the preset compensation voltage value and the current driving voltage" as a theoretical compensation benchmark, the offset of VCOM in this scenario can be accurately offset, avoiding abnormal pixel electrode charging. At the same time, this compensation logic conforms to the driving law of the negative polarity pixel, which does not affect the normal polarity reversal function, and can specifically solve the problems of VCOM interference and abnormal pixel charging, thereby correcting display errors, ensuring display stability in high resolution and high image quality scenarios, and meeting the development needs of LCD display technology.

[0074] In some feasible examples, combining Figure 6 ,like Figure 7 As shown, the above S1300 can be specifically implemented through the following S1300-4.

[0076] As can be seen from the above, the display method provided in this embodiment of the present disclosure, when the sum of the driving voltage differences is greater than 0, the VCOM is pulled off by the voltage jump of adjacent rows with a large amplitude, and the pulling of negative polarity pixels will further aggravate the VCOM offset. At this time, by using the "difference between the minimum compensation voltage value and the current driving voltage value" as a theoretical compensation benchmark, the offset of VCOM in this scenario can be accurately offset, and the problem of abnormal pixel electrode charging can be corrected. At the same time, the compensation logic conforms to the driving law of negative polarity pixels, which does not disrupt the normal operation of AC polarity reversal, and can specifically solve the core pain points of VCOM interference and abnormal pixel charging, thereby correcting display errors, ensuring display stability in high resolution and high image quality scenarios, and meeting the development needs of LCD display technology.

[0077] In some feasible examples, combining Figure 2 ,like Figure 8 As shown, the above S131 can be specifically implemented through the following S1310.

[0078] S1310. Determine the compensation coefficient of at least one target pixel based on the sum of the driving voltage differences and the sum of the theoretical voltage compensation value of at least one target pixel.

[0079] As described above, the display method provided in this disclosure assigns a unique compensation coefficient to each target pixel by calculating the correlation between the sum of driving voltage differences (reflecting the overall interference intensity) and the sum of theoretical voltage compensation values ​​for each target pixel (reflecting the basic compensation requirements of each pixel). This avoids compensation deviations caused by uniform compensation coefficients and ensures that the compensation force can accurately offset the VCOM offset, thereby correcting the problem of abnormal pixel electrode charging. This method of dynamically determining the compensation coefficient based on actual interference conditions is in line with the driving characteristics of LCDs, and is especially suitable for complex driving scenarios of high-resolution, large-size panels, effectively solving the pain points of VCOM interference and abnormal display in the background art.

[0080] In some feasible examples, combining Figure 2 ,like Figure 9 As shown, the above S132 can be implemented by the following S1320.

[0081] S1320. The product of the theoretical voltage compensation value and the compensation coefficient of at least one target pixel is used to determine the actual voltage compensation value of at least one target pixel.

[0082] As described above, the display method provided in this disclosure determines the theoretical voltage compensation value based on conditions such as pixel polarity and the sum of driving voltage differences, and is used to match the direction of VCOM offset with the basic compensation amplitude. The compensation coefficient is determined based on the sum of the overall driving voltage differences and the sum of the theoretical compensation value, and is used to dynamically adjust the compensation strength so that the compensation intensity matches the actual crosstalk intensity. By multiplying the two to obtain the actual voltage compensation value, the basic compensation amount can be accurately weighted while retaining the polarity and voltage difference compensation logic, avoiding insufficient or excessive compensation. This more realistically and accurately offsets the pulling disturbance of data voltage on VCOM, allowing the pixel electrodes to charge normally as expected, effectively improving the display error problem caused by VCOM fluctuations, and enhancing the image stability and display quality in high-resolution and high-definition display scenarios.

[0083] In some feasible examples, combining Figure 2 ,like Figure 10 As shown, the above S133 can be implemented by the following S1330.

[0084] S1330. Based on the sum of the current driving voltage value and the actual voltage compensation value of the target pixel, determine the fusion compensation voltage value of at least one target pixel.

[0085] As can be seen from the above, the display method provided in this embodiment of the present disclosure, through the fusion calculation of "current driving voltage + actual compensation voltage", applies the compensation logic to a specific voltage value, effectively offsetting the pixel charging abnormality problem caused by VCOM offset, solving the core pain point of "VCOM interference and display distortion" in the background technology, and is highly compatible with the driving characteristics and display requirements of LCD, providing stable voltage support for the normal display of subsequent pixels, and ultimately improving the overall display quality.

[0086] In some feasible examples, combining Figure 1 ,like Figure 11 As shown, the above S14 can be implemented by the following S140 and S141.

[0087] S140. Based on the fusion compensation voltage value of the target pixel, query the preset relationship table to determine the theoretical pixel value corresponding to the fusion compensation voltage value; S141. Use the theoretical pixel value as the compensation pixel value for the target pixel.

[0088] As can be seen from the above, the display method provided in this embodiment of the present disclosure quickly maps the fusion compensation voltage value of the target pixel to the theoretical pixel value through a preset relationship table, and uses it as the compensation pixel value. The calculation is simple and has strong real-time performance. It can effectively connect voltage compensation and actual display control, accurately offset the pulling effect of data voltage jump on VCOM, stabilize pixel electrode charging, improve crosstalk and display abnormality problems, ensure compensation accuracy and screen uniformity, take into account display stability and image quality, adapt to the development needs of high resolution and large size LCD, and do not change the original AC polarity reversal drive architecture or produce image retention.
