[0113] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0114] As described in the background section, in the prior art, display panels suffer from poor display quality for both monochrome and color images. The inventors have discovered that this problem arises because the prior art only performs gamma adjustment on white images, neglecting to adjust gamma for other images. This results in poor display quality when displaying images other than white (e.g., monochrome).

[0115] For the reasons mentioned above, embodiments of the present invention provide a method for determining compensation data for a display panel. Figure 1 This is a flowchart of a method for determining compensation data for a display panel according to an embodiment of the present invention, see reference. Figure 1 The method for determining the compensation data of the display panel includes:

[0116] Step 110: Perform gamma adjustment on the first display screen to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale.

[0117] In the first display screen, the grayscale corresponding to the lit sub-pixels can be equal to the bound-point grayscale. During gamma adjustment in this step, multiple bound-point grayscales can be selected, and the first target driving data corresponding to the color sub-pixels in the first display screen for each bound-point grayscale can be determined. Specifically, the driving data corresponding to the sub-pixels to be lit can be adjusted based on the target brightness and target chromaticity corresponding to the bound-point grayscale in the first display screen. When the target brightness and target chromaticity corresponding to the bound-point grayscale are achieved, the driving data corresponding to the color sub-pixels is set as the first target driving data. In the first display screen, at least two types of luminous color sub-pixels are displayed. The target brightness and target chromaticity corresponding to the bound-point grayscale in the first display screen can be the target brightness and target chromaticity of the color sub-pixels themselves in the bound-point grayscale, or the target brightness and target chromaticity corresponding to the mixed light of each lit luminous color sub-pixel in the first display screen (e.g., when red, green, and blue sub-pixels are all lit, the mixed light of red, green, and blue light is white light). The color subpixel can be any subpixel of any luminous color included in the display panel.

[0118] Step 120: Perform gamma adjustment on the second display screen to obtain the second target driving data corresponding to the set color sub-pixel in the bound point grayscale.

[0119] In the second display screen, the grayscale corresponding to the lit sub-pixels can be equal to the bound-point grayscale. During gamma adjustment in this step, multiple bound-point grayscales can be selected, and the second target driving data corresponding to the color sub-pixels in the second display screen for each bound-point grayscale can be determined. Specifically, the driving data corresponding to the sub-pixels to be lit can be adjusted based on the target brightness and target chromaticity corresponding to the bound-point grayscale in the second display screen. The driving data corresponding to the color sub-pixels is then set as the second target driving data when the target brightness and target chromaticity are achieved. At least one type of luminous color sub-pixel is displayed in the second display screen. The target brightness and target chromaticity corresponding to the bound-point grayscale in the second display screen can be the target brightness and target chromaticity of the colored sub-pixel itself in the bound-point grayscale, or the target brightness and target chromaticity corresponding to the mixed light of each lit luminous color sub-pixel in the second display screen (e.g., when both red and green sub-pixels are lit, the mixed light of red and green is yellow).

[0120] Step 130: Based on the first target driving data and the second target driving data corresponding to the grayscale of each binding point, determine the compensation data of the color sub-pixels in the display grayscale range relative to the first display screen in the second display screen.

[0121] In the first display screen, the number of colors of the illuminated sub-pixels is greater than that in the second display screen, and the grayscale values ​​of the bound pixels are the same in both displays. Specifically, the grayscale values ​​corresponding to the illuminated sub-pixels in both the first and second displays are bound grayscale values. The compensation data can be configured to compensate for the brightness of the display screen where the number of colors of the illuminated sub-pixels is less than that in the first display screen, thereby improving the display effect.

[0122] Optionally, the first target driving data includes a first target data voltage, the second target driving data includes a second target data voltage, and the compensation data includes a data voltage compensation value; or the first target driving data includes a first target gamma register value, the second target driving data includes a second target gamma register value, and the compensation data includes a gamma register compensation value.

[0123] In one optional embodiment of the present invention, the first display screen is a white screen and the second display screen is a monochrome screen; in another optional embodiment of the present invention, the first display screen is a white screen and the second display screen is a mixed color display screen, wherein the sub-pixels of the two luminous colors in the display panel are lit up under the mixed color display screen; in yet another optional embodiment of the present invention, the first display screen is a mixed color display screen and the second display screen is a monochrome display screen.

[0124] In this step, compensation data for the set color sub-pixel within the display grayscale range is determined based on the first target driving data and the second target driving data corresponding to each binding point grayscale. Optionally, in this step, firstly, for each binding point grayscale, compensation data corresponding to the set color sub-pixel within the binding point grayscale is determined based on the first target driving data and the second target driving data corresponding to the binding point grayscale. Then, compensation data for other display grayscales is determined based on the compensation data at the binding point grayscale, thus obtaining compensation data for the set color sub-pixel across the entire grayscale range. This allows for brightness compensation and improved display performance when, during the actual driving process of the display panel, the number of sub-pixel colors illuminated in the display screen is less than the number of sub-pixel colors illuminated in the first display screen. Furthermore, the compensation data can be stored after acquisition. Compared to storing the second driving data, the compensation data occupies relatively less storage space, thus saving storage space.

[0125] When the second display screen is a monochrome display screen, steps 120 and 130 can be performed on the sub-pixels of different luminous colors in the display panel respectively, that is, the sub-pixels of each luminous color are determined as set color sub-pixels, and the compensation data corresponding to each luminous color sub-pixel is determined.

[0126] The method for determining display panel compensation data in this embodiment involves performing gamma adjustment under a first display screen to obtain first target driving data corresponding to a set color sub-pixel at a bound-point grayscale; performing gamma adjustment under a second display screen to obtain second target driving data corresponding to the set color sub-pixel at a bound-point grayscale; and determining the compensation data of the set color sub-pixel within the display grayscale range of the second display screen relative to the first display screen based on the first and second target driving data corresponding to each bound-point grayscale. Since the number of color types of sub-pixels lit under the first display screen is greater than that under the second display screen, compared to the prior art which only performs gamma adjustment under a white screen, this embodiment performs gamma adjustment under display screens of different colors to obtain compensation data of the set color sub-pixel within the display grayscale range of the second display screen relative to the first display screen. This allows for brightness compensation based on this compensation data during the actual driving process of the display panel, when the number of color types of sub-pixels lit in the display screen is less than that in the first display screen, thus improving the display effect of both monochrome and color screens.

[0127] Figure 2 This is a flowchart of another method for determining compensation data for a display panel provided in an embodiment of the present invention, see reference. Figure 2The method for determining the compensation data of the display panel includes:

[0128] Step 210: Perform gamma debugging on the first display screen to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale; this step is the same as step 110 in the above embodiment, and will not be described again here.

[0129] Step 220: Perform gamma debugging on the second display screen to obtain the second target driving data corresponding to the set color sub-pixel in the bound point grayscale; this step is the same as step 120 in the above embodiment, and will not be described again here.

[0130] Step 230: Determine the difference between the driving data of the first target driving data and the second target driving data corresponding to the grayscale of the binding point as the compensation data corresponding to the grayscale of the binding point.

[0131] Optionally, the driving data difference is equal to the difference or ratio between the second target driving data and the first target driving data.

[0132] For example, the first display screen is a white screen, and the second display screen is a red screen. The selected grayscale levels include eight, such as 16 grayscale, 32 grayscale, 64 grayscale, 100 grayscale, 128 grayscale, 192 grayscale, 225 grayscale, and 255 grayscale. In the first display screen, the first target driving data corresponding to the eight grayscale levels are WR_Data16, WR_Data32, WR_Data64, WR_Data100, WR_Data128, WR_Data192, WR_Data225, and WR_Data255, respectively. In the second display screen, the second target driving data corresponding to the eight grayscale levels are RR_Data16, RR_Data32, RR_Data64, RR_Data100, RR_Data128, RR_Data192, RR_Data225, and RR_Data255, respectively. Taking the difference between the driving data and the second target driving data as an example, the driving data difference Δdata16 corresponding to grayscale 16 is RR_Data16-WR_Data16, and the driving data difference Δdata32 corresponding to grayscale 32 is RR_Data32-WR_Data32. The calculation method for the driving data difference corresponding to other bound point grayscales is the same.

[0133] Step 240: Determine the compensation data corresponding to other display gray levels based on the compensation data corresponding to the gray levels of each binding point.

[0134] Optionally, the correspondence between the display grayscale and the compensation data can be determined based on the compensation data corresponding to each grayscale point, or the correspondence between the parameters corresponding to the display grayscale and the compensation data. Then, the compensation data corresponding to other display grayscales can be determined based on the obtained correspondence.

[0135] The parameters corresponding to the displayed grayscale include the target brightness corresponding to the displayed grayscale. In an optional embodiment of the present invention, step 240 includes: determining a first correspondence between the compensation data and the target brightness within the displayed grayscale range based on the compensation data corresponding to each binding point grayscale, wherein the target brightness corresponds to the displayed grayscale; and determining the compensation data corresponding to other displayed grayscales based on the first correspondence.

[0136] Optionally, the first correspondence is obtained through data fitting. For example, the first correspondence is: Δdatai = aLvi^2 + bLvi + c. Here, a, b, and c are constants, Lvi represents the target brightness corresponding to grayscale i, and Δdatai represents the compensation data corresponding to grayscale i. The specific values ​​of a, b, and c are calculated through data fitting.

[0137] For the calculation of compensation data corresponding to any display grayscale, after obtaining the first correspondence, the target brightness corresponding to the display grayscale can be substituted into the first correspondence to obtain the compensation data corresponding to the display grayscale.

[0138] In another optional embodiment of the present invention, step 240 includes: determining a second correspondence between compensation data within the display grayscale range and display grayscale based on the compensation data corresponding to each binding point grayscale; and determining compensation data corresponding to other display grayscale based on the second correspondence.

[0139] Optionally, the first correspondence is obtained by data fitting. For example, the second correspondence is: Δdatai=dGrayi^2+eGrayi+f; where d, e, and f are all constants, Grayi represents the gray level i, and Δdatai represents the compensation data corresponding to the gray level i.

[0140] To calculate the compensation data corresponding to any display grayscale, after obtaining the second correspondence, the display grayscale can be substituted into the second correspondence to obtain the compensation data corresponding to the display grayscale.

[0141] Figure 3 This is a flowchart of another method for determining compensation data for a display panel provided in an embodiment of the present invention, see reference. Figure 3 The method for determining the compensation data of the display panel includes:

[0142] Step 310: Perform gamma adjustment under the first display screen of the reference display brightness level to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale.

[0143] Specifically, display devices such as mobile phones and computers typically include brightness adjustment buttons. Users adjust the overall display brightness of the device using these buttons, with each press corresponding to an input brightness level. Each brightness level corresponds to the brightness of the maximum grayscale level on the display panel. Changing the brightness of the maximum grayscale level affects the brightness of other grayscale levels. Specifically, increasing the brightness of the maximum grayscale level increases the brightness of other grayscale levels; conversely, decreasing the brightness of the maximum grayscale level decreases the brightness of other grayscale levels. Therefore, a higher display brightness results in a higher brightness level and a higher overall brightness, while a lower brightness results in a lower brightness level and a lower overall brightness. Before step 310, at least one brightness level can be set as a baseline brightness level. When there is only one baseline brightness level, the compensation data for other brightness levels is obtained based on the compensation data for that baseline brightness level, resulting in a fast calculation method for determining the compensation data. When there are at least two reference display brightness levels, the compensation data for other display brightness levels are obtained based on the compensation data for at least two reference display brightness levels, which helps to improve the accuracy of the compensation data for other display brightness levels. For example, the reference display brightness level can be selected as the display brightness level corresponding to High Brightness Mode (HBM).

[0144] In this step, multiple bound-point grayscales can be selected under the reference display brightness level, and gamma adjustment can be performed on the first display screen of each bound-point grayscale to determine the first target driving data corresponding to the color sub-pixel in the first display screen of each bound-point grayscale.

[0145] Step 320: Perform gamma adjustment on the second display screen at the reference display brightness level to obtain the second target driving data corresponding to the set color sub-pixel in the bound point grayscale.

[0146] In this step, multiple bound-point grayscales can be selected under the reference display brightness level, and gamma adjustment can be performed on the second display screen of each bound-point grayscale to determine the second target driving data corresponding to the color sub-pixel on the second display screen of each bound-point grayscale.

[0147] Step 330: Based on the first target driving data and the second target driving data corresponding to the grayscale of each binding point under the reference display brightness level, determine the compensation data of the display panel in the display grayscale range of the second display screen at each display brightness level relative to the first display screen.

[0148] Optionally, step 330 may include: determining, based on the first target driving data and the second target driving data corresponding to the grayscale of each bound point at the reference display brightness level, the compensation data of the second display screen at the reference display brightness level relative to the first display screen in the display grayscale range; and determining, based on the compensation data of the set color sub-pixel in the display grayscale range at other display brightness levels, the compensation data of the set color sub-pixel in the display grayscale range at the reference display brightness level.

[0149] Specifically, when calculating the compensation data within the grayscale range under the reference display brightness level, the difference in driving data between the first target driving data and the second target driving data corresponding to the bound-point grayscale under the reference display brightness level can be determined as the compensation data corresponding to the bound-point grayscale (see step 230 in the above embodiment for details). Then, the compensation data corresponding to other display grayscales is determined based on the compensation data corresponding to each bound-point grayscale under the reference display brightness level (see step 240 in the above embodiment for details). After the compensation data corresponding to the set color sub-pixel within the display grayscale range under the reference display brightness level is determined, the compensation data corresponding to the set sub-pixel within the display grayscale range under other display brightness levels can be obtained based on the compensation data corresponding to the reference display brightness level. Optionally, for any display grayscale, the compensation data of the set color sub-pixel within the display grayscale range at non-reference display brightness levels is determined by multiplying the compensation data of the set color sub-pixel under the reference display brightness level with the first set coefficient.

[0150] The first setting coefficient can be preset. Optionally, the first setting coefficient is equal to the ratio of the first brightness and the second brightness, where the first brightness is the target brightness corresponding to the grayscale at a non-reference display brightness level, and the second brightness is the target brightness corresponding to the grayscale at a reference display brightness level.

[0151] The method for determining compensation data for the display panel in this embodiment involves performing gamma adjustment under a first display screen and a second display screen at a reference display brightness level to determine the compensation data corresponding to a set color sub-pixel within the display grayscale range of the reference display brightness level. Based on the compensation data of the set color sub-pixel within the display grayscale range at the reference display brightness level, the compensation data of the set color sub-pixel within the display grayscale range at other display brightness levels is determined. On one hand, by performing gamma adjustment under display screens of different colors, the compensation data of the set color sub-pixel within the display grayscale range of the second display screen relative to the first display screen can be obtained. This allows for brightness compensation during the actual driving process of the display panel, improving the display effect of both monochrome and color images. On the other hand, in this embodiment, gamma adjustment is performed on the first and second display screens at the reference display brightness level. The compensation data in the grayscale range at other display brightness levels can be calculated based on the compensation data at the reference display brightness level. That is, gamma adjustment is not required at other display brightness levels. The efficiency of gamma adjustment can be taken into account. While ensuring that the gamma adjustment process is highly efficient, compensation data in the grayscale range at each display brightness level can be obtained, thereby improving the display effect.

[0152] Optionally, the second display screen can be a monochrome screen. Figure 4 This is a flowchart of another method for determining compensation data for a display panel provided in an embodiment of the present invention, see reference. Figure 4 The method for determining the compensation data of the display panel includes:

[0153] Step 410: Perform gamma debugging on the first display screen to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale; this step is the same as step 110 in the above embodiment, and will not be described again here.

[0154] Step 420: Perform gamma debugging on the second display screen to obtain the second target driving data corresponding to the set color sub-pixel in the bound point grayscale; this step is the same as step 120 in the above embodiment, and will not be repeated here.

[0155] Step 430: Based on the first target driving data and the second target driving data corresponding to the grayscale of each binding point, determine the compensation data of the color sub-pixel in the display grayscale range relative to the first display screen in the second display screen; this step is the same as the process of step 130 in the above embodiment, and will not be repeated here.

[0156] Step 440: Based on the compensation data of the set color sub-pixels in the display grayscale range under the second display screen, determine the compensation data of the set color sub-pixels in the display grayscale range under the third display screen; wherein, the third display screen is a mixed color display screen.

[0157] Specifically, the compensation data for a monochrome display and a mixed-color display with the same grayscale level may differ, which is related to the specific structure of the display panel. The method for determining the compensation data of the display panel in any embodiment of the present invention can be applied to both first-type and second-type display panels. Figure 5 This is a schematic diagram of the structure of the first type of display panel provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of the structure of the second type of display panel provided in an embodiment of the present invention, for reference. Figure 5 and Figure 6 In both the first and second type of display panels, sub-pixels 10 include a first electrode, a light-emitting layer, and a second electrode stacked together. The first electrode can be selected as a cathode, and the second electrode can be selected as an anode. In the first type of display panel, the first electrodes of sub-pixels 10 with different light-emitting colors are electrically connected to each other to form a whole-surface first electrode. In the second type of display panel, at least some of the first electrodes of sub-pixels 10 are insulated from each other; for example, the first electrodes of sub-pixels 10 with different light-emitting colors can be insulated from each other, while the first electrodes of sub-pixels 10 with the same light-emitting color are electrically connected to each other.

[0158] Both the first type of display panel and the second type of display panel also include a first power line VSS. In the first type of display panel, the voltage transmitted by the first power line VSS connected to the first electrode of the entire surface is the same. In the second type of display panel, different first power lines VSS can be connected to the first electrodes of the light-emitting devices in different sub-pixels 10, and the voltages transmitted by different first power lines VSS to different sub-pixels 10 can be different. For example, the first electrode of red sub-pixel 11 is connected to a first power line VSS, the first electrode of green sub-pixel 12 is connected to a first power line VSS, and the first electrode of blue sub-pixel 13 is connected to a first power line VSS. The first power lines VSS connected to red sub-pixels 11, green sub-pixels 12, and blue sub-pixels 13 are different, and the voltages transmitted by different first power lines VSS can be different.

[0159] Both the first-class and second-class display panels also include a second power line. Figure 5 and Figure 6 (Not shown in the image), the display panel also includes pixel circuitry for driving sub-pixels. Figure 7 This is a schematic diagram of the pixel circuit structure in related technologies, for reference. Figure 7The second power line VDD is electrically connected to the pixel circuit, and the driving current generated by the pixel circuit is positively correlated with the voltage transmitted by the second power line VDD. Optionally, the second power line VDD transmitted by the pixel circuits of each sub-pixel is the same. Due to the voltage drop across the second power line VDD, the total current flowing through the second power line VDD differs significantly between monochrome and mixed-color displays. This results in different voltage drops across the second power line VDD for monochrome and mixed-color displays at the same grayscale level, leading to different voltages transmitted by the second power line VDD to the same sub-pixel. Compensation data can be used to compensate for the differences in display effect caused by the voltage drop difference across the second power line VDD. Therefore, the corresponding compensation data may be different for monochrome and mixed-color displays at the same grayscale level.

[0160] Optionally, step 440 above includes: for any display grayscale, determining the compensation data corresponding to the set color sub-pixel in the third display screen based on the product of the compensation data of the set color sub-pixel in the second display screen and the second set coefficient.

[0161] In this step, the compensation data corresponding to the set color sub-pixel under the second display screen is determined by multiplying the compensation data of the set color sub-pixel under the second display screen with the second set coefficient. This makes the determination of compensation data more efficient. Furthermore, after the compensation data corresponding to the set color sub-pixel under the third display screen is determined, the display panel can be driven according to the compensation data corresponding to the set color sub-pixel under the third display screen when it needs to display a mixed color display screen during the actual driving process of the display panel, thereby improving the display effect under the mixed color display screen.

[0162] Based on the above technical solution, optionally, the second set coefficient is greater than 0 and less than 1.

[0163] Specifically, the first display screen is a white screen (all red, green, and blue sub-pixels are lit), the second display screen is a monochrome display screen (one of the red, green, and blue sub-pixels is lit), and the third display screen is a mixed-color display screen (two of the red, green, and blue sub-pixels are lit). Therefore, the total current difference on the second power line between the second and first display screens is greater than the total current difference on the second power line between the third and first display screens. Correspondingly, at the same grayscale, the compensation data for the set color sub-pixels in the third display screen is less than that for the set color sub-pixels in the second display screen. Therefore, the second setting coefficient is greater than 0 and less than 1, ensuring that the compensation data for the mixed-color display screen at the same grayscale is less than that for the monochrome display screen, thus ensuring that the compensation degree for the mixed-color display screen is less than that for the monochrome display screen, and ensuring a good compensation effect for both the mixed-color and monochrome display screens.

[0164] Based on the above embodiments, the second setting coefficient can be obtained before step 440. Optionally, before determining the compensation data corresponding to the set color sub-pixel in the third display screen based on the product of the compensation data of the set color sub-pixel in the second display screen and the second setting coefficient for any display grayscale, the method further includes: performing gamma adjustment in the third display screen to obtain the third target driving data corresponding to the set color sub-pixel in the bound-point grayscale; determining the compensation data of the set color sub-pixel in the display grayscale range of the third display screen relative to the first display screen based on the first target driving data and the third target driving data corresponding to each bound-point grayscale; and determining the second setting coefficient based on the compensation data corresponding to the set color sub-pixel in the third display screen and the second display screen, respectively.

[0165] Specifically, at least one display panel from the same batch can be selected for gamma adjustment under the third display screen, and the above-mentioned steps of determining the second setting coefficient can be performed. Then, the second setting coefficient can be applied to each display panel in the same batch. In this way, the time for determining the corresponding compensation data of the display panels in the same batch under the third display screen can be saved, and the efficiency of the method for determining the compensation data of the display panels can be further improved.

[0166] Figure 8 This is a flowchart of another method for determining compensation data for a display panel provided in an embodiment of the present invention, see reference. Figure 8 The method for determining the compensation data of the display panel includes:

[0167] Step 510: Determine the target brightness of the set color sub-pixel in the second display screen based on the target chromaticity and target brightness corresponding to the grayscale of the bound point in the first display screen.

[0168] The target brightness corresponding to the color sub-pixel in the second display screen can be calculated according to the target brightness and target chromaticity of the first display screen, based on a preset calculation rule. For example, if the first display screen is a white screen and the second display screen is a monochrome screen, the target brightness corresponding to the color sub-pixel can be decomposed from the target brightness and target chromaticity of the white screen.

[0169] Step 520: Based on the target chromaticity and target brightness corresponding to the bound point grayscale in the first display screen, perform gamma adjustment in the first display screen to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale.

[0170] Specifically, when performing gamma adjustment on the first display screen, the driving data provided to the set color sub-pixels can be adjusted to make the first display screen reach the target brightness and target chromaticity corresponding to the bound grayscale, and the driving data when the first display screen reaches the target brightness and target chromaticity corresponding to the bound grayscale is determined as the first target driving data.

[0171] Step 530: Based on the target brightness corresponding to the grayscale of the bound points in the second display screen, perform gamma adjustment in the second display screen to obtain the second target driving data corresponding to the set color sub-pixel in the grayscale of the bound points.

[0172] Specifically, when performing gamma adjustment in the second display screen, the driving data provided to the set color sub-pixel can be adjusted to make the set color sub-pixel in the second display screen reach the target brightness corresponding to the bound point grayscale, and the driving data for the set color sub-pixel in the second display screen to reach the target brightness corresponding to the bound point grayscale is determined as the second target driving data.

[0173] Step 540: Based on the first target driving data and the second target driving data corresponding to the grayscale of each binding point, determine the compensation data of the color sub-pixel in the display grayscale range relative to the first display screen in the second display screen; this step is the same as the process of step 130 in the above embodiment, and will not be repeated here.

[0174] Based on the above embodiments, optionally, after step 130, step 240, step 330, step 440 or step 540, the method further includes: storing the first target driving data and compensation data.

[0175] After storing the first target driving data and compensation data, during the subsequent display process of the display panel, the first target driving data and compensation data can be directly called, and the display can be driven according to the first target driving data and compensation data. For example, when the display panel needs to display a display image of the same color as the first display image, the display panel can be driven to display according to the first target driving data; when the display panel needs to display a display image of a different color than the first display image, the display panel can be driven to display according to the first target driving data and compensation data.

[0176] This invention also provides a method for driving a display panel. Figure 9 This is a flowchart of another display panel driving method provided in an embodiment of the present invention, see reference. Figure 9 The driving method for this display panel includes:

[0177] Step 610: Obtain the target display screen type of the display panel.

[0178] The target display screen types include a fourth display screen and a fifth display screen. The number of colors of the sub-pixels lit up under the fourth display screen is greater than the number of colors of the sub-pixels lit up under the fifth display screen.

[0179] In this embodiment, the fourth display screen has the same color as the first display screen. For example, when the first display screen is white, the fourth display screen is also white. In the fourth display screen, the display grayscale of the sub-pixels can be either bound grayscale or unbound grayscale, that is, the fourth display screen can be the same as or different from the first display screen. This embodiment does not make specific limitations here.

[0180] Step 620: When the target display screen type is the fourth display screen, determine the first final driving data corresponding to the set color sub-pixel based on the first target driving data corresponding to the set color sub-pixel, and provide the first final driving data to the set color sub-pixel.

[0181] Optionally, step 620 includes: when the target display screen type is a fourth display screen, determining the first final driving data corresponding to the set color sub-pixel based on the target display grayscale and the first target driving data corresponding to the bound point grayscale, and providing the first final driving data to the set color sub-pixel. In an optional embodiment of the present invention, when the target display grayscale is equal to the bound point grayscale, the first target driving data corresponding to the bound point grayscale is determined as the first final driving data corresponding to the set color sub-pixel under the target display grayscale; a third correspondence is determined based on each bound point grayscale and the first final driving data corresponding to each bound point grayscale, the third correspondence being the correspondence between the display grayscale and the first final driving data; when the target display grayscale is not equal to the bound point grayscale, the first final driving data corresponding to the target display grayscale is determined based on the third correspondence.

[0182] In another alternative embodiment, when the fourth display screen is the same as the first display screen, the first target driving data corresponding to the set color sub-pixel under the target display grayscale can be determined as the first final driving data corresponding to the set color sub-pixel; when the fourth display screen is different from the first display screen, the first target driving data corresponding to different binding point grayscales can be interpolated according to the target display grayscale corresponding to the set sub-pixel to obtain the first final driving data corresponding to the set color sub-pixel under the target display grayscale.

[0183] Step 630: When the target display screen type is the fifth display screen, determine the second final driving data corresponding to the set color sub-pixel under the fifth display screen based on the first target driving data and the compensation data corresponding to the set color sub-pixel, and provide the second final driving data to the set color sub-pixel.

[0184] The compensation data is determined using the compensation data determination method for the display panel of any of the above embodiments of the present invention.

[0185] Optionally, step 630 includes: when the target display screen type is a fifth display screen, determining the second final driving data corresponding to the set color sub-pixel at the target display grayscale under the fifth display screen based on the first target driving data, the compensation data corresponding to the set color sub-pixel, and the target display grayscale corresponding to the set color sub-pixel. In an optional embodiment of the invention, when the target display grayscale is equal to the binding point grayscale, the second final driving data corresponding to the set color sub-pixel at the target display grayscale is determined based on the first target driving data and the corresponding compensation data corresponding to the binding point grayscale; a fourth correspondence is determined based on each binding point grayscale and the second final driving data corresponding to each binding point grayscale, the fourth correspondence being the correspondence between the display grayscale and the second final driving data; when the target display grayscale is not equal to the binding point grayscale, the second final driving data corresponding to the target display grayscale is determined based on the fourth correspondence.

[0186] When the target display grayscale corresponding to the color subpixel is set to be equal to the bound point grayscale, the second final driving data can be determined based on the first target driving data and compensation data corresponding to the bound point grayscale. For example, in the above method for determining the compensation data of the display panel, when the driving data difference is the difference between the second target driving data and the first target driving data, the sum of the first target driving data and compensation data corresponding to the bound point grayscale is used to determine the second final driving data.

[0187] In another optional embodiment of the present invention, when the target display grayscale corresponding to the set color sub-pixel is not equal to the bound point grayscale, the initial driving data corresponding to the target display grayscale can be obtained by interpolating the first target driving data corresponding to at least two bound point grayscales, and the compensation data corresponding to the target display grayscale can be obtained by interpolating the compensation data corresponding to at least two bound point grayscales. Then, the second final driving data is determined based on the initial driving data and the compensation data. For example, in the above method for determining the compensation data of the display panel, when the difference in driving data is the difference between the second target driving data and the first target driving data, the second final driving data is determined by the sum of the initial driving data and the compensation data corresponding to the target display grayscale.

[0188] Optionally, in the fourth display screen, the target display grayscale corresponding to the color sub-pixels is set to be completely or not completely the same. Optionally, in the fifth display screen, the target display grayscale corresponding to the color sub-pixels is set to be completely or not completely the same. The driving method of the display panel in this embodiment can be applied to the driving display of the same display screen as the first display screen and the same display screen as the second display screen, and can also be applied to the driving display of different display screens than the same display screen as the first display screen or different display screens than the same display screen as the second display screen, ensuring good display effect in each display screen.

[0189] The display panel driving method of the present invention drives the display panel by using the compensation data determined by the compensation data determination method of the display panel according to any of the above embodiments of the present invention, which can ensure and improve the display effect of the color display screen.

[0190] Optionally, in the above embodiments, the first display screen, the second display screen, the fourth display screen, and the fifth display screen are displayed on the same display panel. The first or second correspondence is determined by the first and second display screens. When the fourth and fifth display screens need to be displayed, they are obtained through the first or second correspondence. By performing multiple adjustments on each display panel, the accuracy of the first or second correspondence is improved.

[0191] In other optional embodiments of the present invention, the first and second display screens are displayed on the same display panel, the fourth and fifth display screens are displayed on the same display panel, the first and fourth display screens are displayed on different display panels, and the second and fifth display screens are displayed on different display panels. By determining a first or second correspondence between the first and second display screens of the test display panel, other display panels can accurately obtain the second driving data of the fifth display screen through the first target driving data of the fourth display screen and the compensation data obtained through the first or second correspondence, thereby reducing the debugging time of other display panels.

[0192] Figure 10 This is a flowchart of another display panel driving method provided in an embodiment of the present invention, see reference. Figure 10 The driving method for this display panel includes:

[0193] Step 710: Obtain the target display screen type of the display panel.

[0194] The target display screen types include a fourth display screen and a fifth display screen. The number of colors of the sub-pixels lit up under the fourth display screen is greater than the number of colors of the sub-pixels lit up under the fifth display screen.

[0195] Step 720: When the target display screen type is the fourth display screen, determine the first final driving data corresponding to the set color sub-pixel based on the first target driving data corresponding to the set color sub-pixel, and provide the first final driving data to the set color sub-pixel.

[0196] Optionally, step 720 includes: when the target display screen type is the fourth display screen, determining the first final driving data corresponding to the set color sub-pixel based on the first target driving data corresponding to the target display grayscale and the bound point grayscale of the set color sub-pixel, and providing the first final driving data to the set color sub-pixel.

[0197] Optionally, when the target display screen type is the fourth display screen, the first final driving data corresponding to the set color sub-pixel is determined based on the first target driving data corresponding to the target display grayscale and the bound point grayscale of the set color sub-pixel, and the first final driving data is provided to the set color sub-pixel, including:

[0198] Gamma adjustment is performed on the fourth display screen to obtain the first target driving data corresponding to the set color sub-pixel in the bound point grayscale, and the first target driving data corresponding to the bound point grayscale is determined as the first final driving data corresponding to the bound point grayscale; a third correspondence is determined based on the bound point grayscale and the first final driving data corresponding to the bound point grayscale; the third correspondence is the correspondence between the display grayscale and the first final driving data; based on the display grayscale corresponding to the set color sub-pixel in the fourth display screen and the third correspondence, the first final driving data corresponding to the set color sub-pixel in the display grayscale corresponding to the set color sub-pixel in the fourth display screen is determined.

[0199] Optionally, the fourth display screen and the first display screen are displayed on different display panels.

[0200] Step 730: When the target display screen type is the fifth display screen, determine the compensation data of the set color sub-pixel in the fifth display screen according to the target brightness or display grayscale corresponding to the set color sub-pixel in the fifth display screen.

[0201] The compensation data is obtained by substituting the target brightness corresponding to the set color sub-pixel in the fifth display screen into the first correspondence relationship in the compensation data acquisition method of the above embodiment, or by substituting the target brightness corresponding to the set color sub-pixel in the fifth display screen into the second correspondence relationship in the compensation data acquisition method of the above embodiment.

[0202] Step 740: Determine the sum of the target data and compensation data corresponding to the set color sub-pixel under the same target brightness or display grayscale in the fourth display screen as the second final driving data corresponding to the set color sub-pixel in the fifth display screen.

[0203] The fourth display screen has the same color as the first display screen.

[0204] The display panel driving method in this embodiment only performs gamma debugging on the fourth display screen to obtain the first target driving data when determining compensation data, without needing to perform gamma debugging on other display screens. This improves the efficiency of gamma debugging and thus helps to improve production efficiency.

[0205] This invention also provides a display panel, which can be... Figure 5 The display panel shown can also be Figure 6 The display panel shown is driven using the display panel driving method described in the above embodiment of the present invention.

[0206] Figure 11 This is a cross-sectional view of a display panel provided in an embodiment of the present invention. Figure 11 Can correspond Figure 6The sectional view obtained by cutting along BB'. Figure 12 This is an enlarged view of the isolation structure provided in an embodiment of the present invention, for reference. Figure 6 , Figure 11 and Figure 12 The display panel includes: a plurality of sub-pixels 10, each sub-pixel 10 including a first pole 103; and an isolation structure 2, the isolation structure 20 enclosing to form a plurality of isolation openings, each first pole 103 being located in a corresponding isolation opening and overlapping with a corresponding isolation structure 20.

[0207] Optionally, the display panel includes a driving circuit layer and an isolation structure 20, with both the isolation structure 20 and the sub-pixels 10 located on the driving circuit layer. The isolation structure 20 encloses multiple isolation openings; the sub-pixels 10 are at least partially disposed within the isolation openings, and each sub-pixel 10 includes a stacked second electrode 101, a light-emitting layer 102, and a first electrode 103, with the first electrode 103 electrically connected to at least a portion of the isolation structure 20. The isolation structure 20 can also be electrically connected to a first power line VSS. The isolation structure 20 has a certain thickness, such that the light-emitting layers 102 of adjacent sub-pixels 10 are separated at the isolation structure 20, preventing color mixing caused by different light-emitting colors of adjacent sub-pixels 10. The isolation structure 20 includes a support portion 21 and a partition portion 22, with the support portion 21 located between the partition portion 22 and the pixel definition layer 40; the orthographic projection of the partition portion 22 on the pixel definition layer covers the orthographic projection of the support portion 21 on the pixel definition layer 40; the first electrode 101 of the sub-pixels 10 is electrically connected to the support portion 21. The support portion 21 can be made of a conductive material, and the first poles 101 of adjacent sub-pixels 10 are all connected to the support portion 21, so that the first poles 101 of adjacent sub-pixels 10 are electrically connected through the support portion 21. The support portion 21 can be made of aluminum. The partition portion 22 can be made of a conductive material and / or an insulating material, such as titanium, silicon nitride, or silicon oxide. Optionally, the first poles 103 of sub-pixels 10 with the same emission color are electrically connected through the isolation structure 20. Optionally, the first poles 103 of sub-pixels 10 with different emission colors are insulated from each other, and the isolation structures 20 connecting the first poles 103 of sub-pixels 10 with different emission colors are insulated from each other. This configuration reduces interference between sub-pixels 10 with different emission colors, which is beneficial to improving the display effect.

[0208] Continue to refer to Figure 6 , Figure 11 and Figure 12Optionally, the display panel also includes multiple first power lines VSS, with the first poles of sub-pixels 10 of different luminous colors connected to different first power lines VSS. For example, the first pole of a sub-pixel 10 is electrically connected to an isolation structure 20, and the first poles corresponding to sub-pixels 10 of the same luminous color are connected to different first power lines VSS through the isolation structure 20. This allows for independent control of the voltage on the first power lines VSS connected to sub-pixels 10 of different luminous colors. Because sub-pixels 10 of different luminous colors have different luminous efficiencies, setting the first power lines VSS of sub-pixels 10 of different luminous colors to be independent allows the power lines VSS connected to sub-pixels 10 of different luminous colors to have different power supply voltages, which is beneficial for improving the display effect.

[0209] As described in the above embodiments, optionally, the display panel further includes a second power line, which is electrically connected to the pixel circuits for driving each sub-pixel, and the driving current generated by the pixel circuits is related to the voltage on the second power line.

[0210] Optionally, the display panel also includes multiple data lines, which are electrically connected to pixel circuitry used to drive sub-pixels. These data lines are used to transmit first target driving data or second target driving data.
