Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a driving method for a display panel and a display panel. Background Art

[0002] Display panels are developing towards improving transmittance. During this development process, some pixel designs and architecture designs may cause serious vertical crosstalk problems.

[0003] During the display panel manufacturing process, due to process issues, pixels cannot be accurately positioned between two adjacent data lines. In other words, the distances between the pixel and the two adjacent data lines are unequal, resulting in unequal parasitic capacitances between the pixel and the left and right data lines. This causes inconsistent voltage effects on the pixel. Due to the uneven voltage distribution on both sides of the pixel, the voltage effects of the two adjacent data lines on the pixel cannot be offset, causing voltage fluctuations in the pixel, causing the pixel to become brighter or darker, and resulting in visible color shift.

[0004] In view of this, a driving method is urgently needed in the art to solve the display abnormality problem caused by vertical crosstalk caused by the different parasitic capacitances between pixels and the left and right data lines, resulting in the pixels being affected by parasitic capacitance coupling.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0031] The embodiment of the present application provides a driving method for a display panel and a display panel, which can solve the display abnormality problem caused by vertical crosstalk generated by parasitic capacitance on the pixel unit by adjusting the grayscale value of the pixel unit. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments. In addition, in the description of this application, the term "including" means "including but not limited to". The terms "first", "second", "third", etc. are only used as labels to distinguish different objects, rather than to describe a specific order.

[0032] See also Figure 1a 、 Figure 1b 、 Figure 2a as well as Figure 2b , Figure 1aThis is one of the initial vertical crosstalk phenomenon diagrams provided in an embodiment of the present application; Figure 1b To cause Figure 1a Schematic diagram of the vertical crosstalk phenomenon; Figure 2a This is the second diagram of the vertical crosstalk phenomenon of the initial screen provided by the embodiment of the present application; Figure 2b To cause Figure 2a Schematic diagram of the vertical crosstalk phenomenon.

[0033] like Figure 1a 、 Figure 1b As shown, the initial screen includes a first display area 10, a second display area 20 and a third display area 30 arranged along a first direction X, the second display area 20 includes a first sub-display area 21, a second sub-display area 22 and a third sub-display area 23 arranged along a second direction Y, and the second sub-display area 22 is located between the third sub-display area 23 and the first sub-display area 21.

[0034] It should be noted that the first direction X is a direction extending along the scan lines, and the second direction Y is a direction extending along the data lines.

[0035] like Figure 1a 、 Figure 1b As shown, the brightness of the first display area 10 and / or the third display area 30 is affected by the second sub-display area 22, making it brighter or darker than the target brightness of the first display area 10 and / or the third display area 30, resulting in a gray background with a white frame. Specifically, the gray background with a white frame on the initial screen is due to the parasitic capacitance coupling phenomenon caused by the unequal distances between the pixels and the data lines on the left and right sides.

[0036] like Figure 2a 、 Figure 2b As shown, the brightness of the first display area 10 and / or the third display area 30 is affected by the second sub-display area 22, making it brighter or darker than the target brightness of the first display area 10 and / or the third display area 30, resulting in a gray background with a colored frame. Specifically, the gray background with a colored frame on the initial screen is due to parasitic capacitance coupling caused by the unequal voltages on the left and right sides of the pixel and the unequal distances between the pixel and the left and right data lines.

[0037] See also Figures 1 to 4 , Figure 1 This is a schematic diagram of a first flow chart of a method for driving a display panel provided in an embodiment of the present application; Figure 2 This is a second flow chart of the method for driving a display panel provided in an embodiment of the present application; Figure 3 yes Figure 1 Schematic diagram of the sub-step flow of step S10; Figure 4 yes Figure 1 Schematic diagram of the sub-step flow of step S00. Figure 1As shown, an embodiment of the present application provides a method for driving a display panel, comprising the following steps:

[0038] S10 , receiving image data of an initial frame, and respectively obtaining a first grayscale voltage difference of a first pixel column and a second grayscale voltage difference of a second pixel column in two adjacent frames of the initial frame, wherein the first pixel column is adjacent to the second pixel column.

[0039] S20 , determining grayscale voltage compensation values of the first pixel column and the second pixel column based on the first grayscale voltage difference and the second grayscale voltage difference.

[0040] S30 , adjusting a first target grayscale voltage value of the first pixel column and a second target grayscale voltage value of the second pixel column based on the grayscale voltage compensation values of the first pixel column and the second pixel column, and outputting the adjusted image data to display an initial picture.

[0041] Among them, Figure 2 As shown, before step S10, the following steps are also included:

[0042] S00: Receive image data of an initial frame, and obtain a first initial grayscale voltage value of a first pixel column and a second initial grayscale voltage value of a second pixel column in the image data.

[0043] It should be noted that when no vertical crosstalk occurs, the first grayscale voltage difference and the second grayscale voltage difference should be close to 0, that is, the grayscale voltages of the first pixel column and the second pixel column in the two frames are stable and unchanged.

[0044] If the absolute value of the first grayscale voltage difference and / or the absolute value of the second grayscale voltage difference are large, it indicates that vertical crosstalk has occurred in the initial image. As mentioned above, vertical crosstalk between pixels occurs because the distances between the pixel and two adjacent data lines are unequal, resulting in unequal parasitic capacitances between the pixel and the left and right data lines. This causes inconsistent voltage effects on the pixel. Due to the uneven voltage distribution on both sides of the pixel, the voltage effects of the two adjacent data lines on the pixel cannot be offset, causing voltage fluctuations in the pixel, causing the pixel to become brighter or darker, and resulting in visible color shift.

[0045] In an embodiment of the application, the grayscale voltages of the first pixel column and the second pixel column in two adjacent frames of the initial picture are collected, the difference between the two grayscale voltages of the first pixel column is calculated to obtain a first grayscale voltage difference, and the difference between the two grayscale voltages of the second pixel column is calculated to obtain a second grayscale voltage difference, and the grayscale voltages of the first pixel column and the second pixel column are compensated based on the first grayscale voltage difference and the second grayscale voltage difference until the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both close to 0.

[0046] The method provided in the embodiment of the present application realizes an acquisition feedback adjustment process based on the first grayscale voltage difference and the second grayscale voltage difference of the adjacent first pixel column and the second pixel column in two adjacent frames of initial pictures. The adjustment method is to determine the grayscale voltage compensation values of the first pixel column and the second pixel column based on the first grayscale voltage difference and the second grayscale voltage difference, and adjust the first target grayscale voltage value of the first pixel column and the second target grayscale voltage value of the second pixel column based on the grayscale voltage compensation values of the first pixel column and the second pixel column. No manual adjustment by technicians is required, thereby improving the adjustment efficiency of the pixel grayscale voltage, and ultimately effectively improving the vertical crosstalk problem of the display panel.

[0047] like Figure 3 As shown, the steps of receiving image data of an initial frame and respectively obtaining a first grayscale voltage difference value of a first pixel column and a second grayscale voltage difference value of a second pixel column in two adjacent frames of the initial frame specifically include:

[0048] S101, receiving image data of an initial picture, obtaining a first grayscale voltage value corresponding to a first pixel column and a second grayscale voltage value corresponding to a second pixel column in an n-th frame of the initial picture;

[0049] S102, obtaining a third grayscale voltage value corresponding to the first pixel column and a fourth grayscale voltage value corresponding to the second pixel column in the (n+1)th frame of the initial picture;

[0050] S103, determining a first grayscale voltage difference value of the first pixel column based on a difference between the first grayscale voltage value and the third grayscale voltage value, and determining a second grayscale voltage difference value of the second pixel column based on a difference between the second grayscale voltage value and the fourth grayscale voltage value;

[0051] Wherein, n is a positive integer greater than or equal to 1.

[0052] In the embodiment of the present application, the first data line provides the first grayscale voltage and the third grayscale voltage to the input terminal of the first pixel column, and the second data line provides the second grayscale voltage and the fourth grayscale voltage to the input terminal of the second pixel column.

[0053] In the embodiment of the present application, the step of determining the grayscale voltage compensation values of the first pixel column and the second pixel column based on the first grayscale voltage difference and the second grayscale voltage difference specifically includes the following compensation relationship:

[0054]

[0055] Among them, Reg represents the grayscale voltage compensation value, comp represents the compensation coefficient, DatapreL represents the first grayscale voltage value, DatacurL represents the third grayscale voltage value, Offset represents the distance from the first pixel column to the first data line (the distance between the first data line and the second data line ranges from 0 to 256 microns), DatapreR represents the second grayscale voltage value, DatacurR represents the fourth grayscale voltage value, and ImgH represents the number of pixel rows.

[0056] It should be noted that the compensation coefficient needs to be adjusted according to the compensation effect of the initial picture. First, the initial compensation coefficient is written according to the initial compensation coefficient table to obtain the corresponding grayscale voltage compensation value Reg. The target grayscale voltage is adjusted according to the grayscale voltage compensation value to adjust the display grayscale of the initial picture. By adjusting the initial compensation coefficient until the display grayscale of the initial picture reaches the target grayscale, the corresponding initial compensation coefficient is stored as the compensation coefficient.

[0057] like Figure 4 As shown, the steps of receiving image data of an initial screen and obtaining a first initial grayscale voltage value of a first pixel column and a second initial grayscale voltage value of a second pixel column in the image data specifically include:

[0058] S001, receiving image data of an initial picture, and obtaining a first grayscale value of a first pixel column and a second grayscale value of a second pixel column in the image data;

[0059] S002. Determine a first initial grayscale voltage value corresponding to the first grayscale value and a second initial grayscale voltage value corresponding to the second grayscale value according to a preset comparison table, wherein the preset comparison table includes a correspondence between grayscale values and grayscale voltage values.

[0060] In the embodiment of the present application, the steps of adjusting the first target grayscale voltage value on the first data line corresponding to the first pixel column and the second target grayscale voltage value on the second data line corresponding to the second pixel column based on the grayscale voltage compensation values of the first pixel column and the second pixel column, and outputting the adjusted image data to display the initial image, specifically include the following compensation relationship: V out =V in -Reg, where V out Represents the first target grayscale voltage value / the second target grayscale voltage value, V in represents the first initial grayscale voltage value / the second initial grayscale voltage value, and Reg represents the grayscale voltage compensation value.

[0061] See also Figure 5 , Figure 5 FIG. 1 is a third flow chart of the method for driving a display panel provided in an embodiment of the present application. Figure 5As shown, the present application provides another method for driving a display panel. The difference between the driving method and the above driving method is that before the step of adjusting the first target grayscale voltage value of the first pixel column and the second target grayscale voltage value of the second pixel column based on the grayscale voltage compensation values of the first pixel column and the second pixel column, and outputting the adjusted image data to display an initial image, the method further includes the following steps:

[0062] S40, determining whether the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both smaller than a preset threshold;

[0063] If not, the first target grayscale voltage value on the first data line corresponding to the first pixel column and the second target grayscale voltage value on the second data line corresponding to the second pixel column are adjusted based on the grayscale voltage compensation values of the first pixel column and the second pixel column, and the adjusted image data is output to display the initial picture.

[0064] Specifically, if the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both less than the preset threshold, then there is no need to adjust the first target grayscale voltage value on the first data line corresponding to the first pixel row and the second target grayscale voltage value on the second data line corresponding to the second pixel row, and the process returns to step S10 to re-execute detection feedback adjustments for other initial images or other pixel rows. If either the absolute value of the first grayscale voltage difference or the absolute value of the second grayscale voltage difference is greater than the preset threshold or both are greater than the preset threshold, then the first target grayscale voltage value on the first data line corresponding to the first pixel row and the second target grayscale voltage value on the second data line corresponding to the second pixel row are adjusted based on the grayscale voltage compensation values for the first pixel row and the second pixel row, and the adjusted image data is output to display the initial image.

[0065] like Figure 5 As shown, another display panel driving method provided in an embodiment of the present application includes the following steps:

[0066] S00: Receive image data of an initial frame, and obtain a first initial grayscale voltage value of a first pixel column and a second initial grayscale voltage value of a second pixel column in the image data.

[0067] S10 , receiving image data of an initial frame, and respectively obtaining a first grayscale voltage difference of a first pixel column and a second grayscale voltage difference of a second pixel column in two adjacent frames of the initial frame, wherein the first pixel column is adjacent to the second pixel column.

[0068] S20 , determining grayscale voltage compensation values of the first pixel column and the second pixel column based on the first grayscale voltage difference and the second grayscale voltage difference.

[0069] S40 , determining whether the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both smaller than a preset threshold.

[0070] S30 , if not, adjusting the first target grayscale voltage value of the first pixel row and the second target grayscale voltage value of the second pixel row based on the grayscale voltage compensation values of the first pixel row and the second pixel row, and outputting the adjusted image data to display the initial picture.

[0071] Specifically, if the absolute value of the first grayscale voltage difference and / or the absolute value of the second grayscale voltage difference is greater than a preset threshold, it indicates that vertical crosstalk has occurred in the initial image. As mentioned above, vertical crosstalk between pixels occurs because the distances between a pixel and two adjacent data lines are unequal, resulting in unequal parasitic capacitances between the pixel and the left and right data lines. This causes inconsistent voltage effects on the pixel. Due to the uneven voltage distribution on both sides of the pixel, the voltage effects of the two adjacent data lines on the pixel cannot be offset, resulting in voltage fluctuations in the pixel, causing the pixel to become brighter or darker, and resulting in visible color shift.

[0072] If the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both smaller than the preset threshold, the process returns to step S10 and re-executes the detection feedback adjustment of other initial frames or other pixel rows.

[0073] In an embodiment of the application, the grayscale voltages of the first pixel column and the second pixel column in two adjacent frames of the initial picture are collected, the difference between the two grayscale voltages of the first pixel column is calculated to obtain the first grayscale voltage difference, and the difference between the two grayscale voltages of the second pixel column is calculated to obtain the second grayscale voltage difference, and then the numerical relationship between the first grayscale voltage difference and the second grayscale voltage difference and the preset threshold is judged to determine whether to compensate the grayscale voltages of the first pixel column and the second pixel column. When the absolute value of the first grayscale voltage difference and / or the absolute value of the second grayscale voltage difference is greater than the preset threshold, the grayscale voltages of the first pixel column and / or the second pixel column are compensated until the absolute value of the first grayscale voltage difference and the absolute value of the second grayscale voltage difference are both less than the preset threshold.

[0074] The driving method of the display panel provided in the embodiment of the present application, by adding a step of determining the numerical relationship between the first grayscale voltage difference and the second grayscale voltage difference and a preset threshold value, is beneficial for effectively improving the vertical crosstalk problem of the display panel while being able to more specifically perform grayscale voltage compensation on pixels where the crosstalk phenomenon is more obvious, thereby reducing power consumption and saving costs.

[0077] In the embodiment of the present application, the acquisition module 10 is further configured to: acquire a first initial grayscale voltage value of a first pixel column and a second initial grayscale voltage value of a second pixel column in the image data. Specifically, the acquisition module 10 is further configured to receive image data of an initial screen, acquire a first grayscale value of the first pixel column and a second grayscale value of the second pixel column in the image data, and determine a first initial grayscale voltage value corresponding to the first grayscale value and a second initial grayscale voltage value corresponding to the second grayscale value according to a preset comparison table, wherein the preset comparison table includes a correspondence between grayscale values and grayscale voltage values.
