Description

Technical Field

[0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, and specifically to a display panel and a compensation method thereof, and a device for generating a compensated grayscale. Background Art

[0002] Considering the cost of data driver chips, display terminals can currently adopt a three-gate drive architecture to reduce the number of data lines to 1 / 3 of the normal drive architecture. At the same time, the number of scan lines is increased to 3 times the normal drive architecture, so that the width and charging time of each gate pulse are also reduced to 1 / 3 of the normal drive architecture.

[0003] In the three-gate driving architecture, on the one hand, due to the reduction in the number of data driving chips, the distance between two adjacent data driving chips is large, resulting in a large difference in the attenuation degree of the electrical signal transmitted to the two adjacent data driving chips; on the other hand, Figure 1 As shown, when a pure color picture is displayed, the amplitude of the signal on the same data line (each of Da1, Da2, Da3 to Dan) is always in a high and low changing state, that is, it presents an overloaded picture. In addition, after each gate line (each of G1, G2, G3 to Gn) turns on the corresponding row of pixels, the charging time of each row of pixels is insufficient, which will cause the brightness difference of the display areas controlled by the two adjacent data driver chips to be more obvious, resulting in a stronger sense of boundary.

[0004] Therefore, the phenomenon of strong boundary sense in the display screen of the display terminal of the existing three-gate driving architecture needs to be improved urgently. Summary of the invention

[0048] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0049] In the description of the present invention, the terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the said features. In addition, it should be noted that the drawings only provide structures that are closely related to the present invention, and some details that are not closely related to the invention are omitted. The purpose is to simplify the drawings and make the invention clear at a glance, rather than to indicate that the actual device is the same as the attached structure. Figure 1 The same is not a limitation of the actual device.

[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase at various times in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] The present invention provides a compensation method for a display panel, which includes but is not limited to the following embodiments and combinations of the following embodiments.

[0052] In one embodiment, if Figure 2 As shown, the compensation method of the display panel includes but is not limited to the following steps.

[0053] S1, obtaining a first compensated grayscale corresponding to a first original grayscale of a first sub-pixel in a first display portion, and obtaining a second compensated grayscale corresponding to the first original grayscale of a second sub-pixel in a second display portion, the color of the first sub-pixel is the same as the color of the second sub-pixel, the first compensated grayscale is determined at least based on a second brightness of the second sub-pixel at the first original grayscale, and the second compensated grayscale is determined at least based on a first brightness of the first sub-pixel at the first original grayscale.

[0054] Specifically, the display panel including the first display unit and the second display unit may be a self-luminous display panel or a liquid crystal display panel. The sub-pixels in the self-luminous display panel emit light under the driving current generated by the data voltage through the self-luminous device, and the luminous brightness of the sub-pixels is related to the current flowing through the self-luminous device and the duration of the current; the sub-pixels in the liquid crystal display panel emit light through the light of the backlight source through the liquid crystal layer, and the transmittance of the liquid crystal layer is related to the voltage applied to both ends of the liquid crystal layer.

[0055] Among them, the steps before step S1 may include but are not limited to the following steps: dividing the display area of ​​the display panel into at least a first display part and a second display part, the first display part includes a plurality of first sub-pixels, the second display part includes a plurality of second sub-pixels, and the color of the first sub-pixels is the same as the color of the second sub-pixels.

[0056] Wherein, before step S1, the following steps may also be included but not limited to: obtaining a first mapping relationship between the brightness value and the grayscale value of the first sub-pixel and a second mapping relationship between the brightness value and the grayscale value of the second sub-pixel. In addition, the first brightness, the second brightness, the first compensation grayscale and the second compensation grayscale are determined according to the first mapping relationship and the second mapping relationship.

[0057] Specifically, each sub-pixel in the display panel may have a corresponding gamma mapping relationship (including but not limited to a gamma curve and a gamma table). Here, the gamma mapping relationship is described as a gamma curve. Further, if the difference between different regions in the display panel is not considered, it can be considered that sub-pixels of the same color correspond to the same gamma curve. Specifically, Figure 3 As shown, the horizontal axis of the gamma curve can represent the grayscale value corresponding to the data voltage acting on a sub-pixel, and it can be considered that the grayscale value and the data voltage correspond one to one, and the vertical axis of the gamma curve represents the brightness value presented by the sub-pixel under the action of the voltage value, and it can be considered that the relationship between the brightness value and the grayscale value in different gamma curves is different. In particular, considering the differences between different areas in the display panel, the first sub-pixel in the first display part and the second sub-pixel in the second display part in this embodiment can have a first gamma curve (included in the first mapping relationship) and a second gamma curve (included in the second mapping relationship) as their respective gamma curves, even if they have the same color.

[0058] Specifically, the first brightness in step S1 of this embodiment can be the value of the brightness value corresponding to the grayscale value equal to the first original grayscale in the first gamma curve. Similarly, the second brightness can be the value of the brightness value corresponding to the grayscale value equal to the first original grayscale in the second gamma curve. The first brightness is not equal to the second brightness, and the difference between the two can represent the brightness difference presented by sub-pixels (i.e., the first sub-pixel and the second sub-pixel) of the same color (e.g., green) when the grayscale values ​​are equal to the first original grayscale. It should be noted that if the above brightness difference exists, it will at least cause the sub-pixels of the same color (e.g., green) in the first display unit and the second display unit to emit light under the same data voltage, respectively presenting different brightnesses, resulting in uneven display of the screen.

[0059] Among them, as discussed above, in this embodiment, the first compensation grayscale can also be determined based on the first gamma curve, at least according to the grayscale value corresponding to the data voltage that needs to be applied to the first sub-pixel when the light is emitted as the second brightness. Similarly, the second compensation grayscale can also be determined based on the second gamma curve, at least according to the grayscale value corresponding to the data voltage that needs to be applied to the second sub-pixel when the light is emitted as the first brightness. Therefore, it can be considered that the first compensation grayscale takes into account the difference between the first gamma curve of the first sub-pixel and the second gamma curve of the second sub-pixel at the first original grayscale, and the second compensation grayscale also takes into account the difference between the second gamma curve of the second sub-pixel and the first gamma curve of the first sub-pixel at the first original grayscale.

[0060] S2, controlling the first sub-pixel in the first part and the second sub-pixel in the first part to emit light at the first original grayscale, controlling the first sub-pixel in the second part to emit light at the first compensated grayscale, and controlling the second sub-pixel in the second part to emit light at the second compensated grayscale.

[0061] Specifically, in combination with the above discussion, it can be seen that this embodiment can be presented as: in the first display portion, the first sub-pixel of the first part emits light at the first original grayscale to present a first brightness, and the first sub-pixel of the second part emits light at the first compensated grayscale to present a brightness limited by the second brightness (first compensated brightness); in the second display portion, the second sub-pixel of the first part emits light at the second original grayscale to present a second brightness (second compensated brightness), and the second sub-pixel of the second part emits light at the second compensated grayscale to present a brightness limited by the first brightness.

[0062] It can be understood that the brightness finally presented in the first display unit is composed of multiple first brightnesses and multiple first compensation brightnesses (limited by the second brightness), which can be closer to the total brightness composed of the second brightness in the second display unit compared to the brightness composed entirely of the first brightness, so as to reduce the difference between the display screen of the first display unit and the display screen of the second display unit; further, the brightness finally presented in the second display unit is composed of multiple second brightnesses and multiple second compensation brightnesses (limited by the first brightness), which can be closer to the total brightness composed of the first brightness in the first display unit compared to the brightness composed entirely of the second brightness, so as to also reduce the difference between the display screen of the second display unit and the display screen of the first display unit. Therefore, this embodiment can effectively reduce the brightness difference of the display screen in different areas of the display panel and improve the uniformity of the overall display screen.

[0063] In particular, the first compensation grayscale is the grayscale value of the first sub-pixel corresponding to the second brightness, and the second compensation grayscale is the grayscale value of the second sub-pixel corresponding to the first brightness. Specifically, here, the grayscale value corresponding to the data voltage to be applied to the first sub-pixel when the light is presented as the second brightness is obtained according to the first gamma curve as the first compensation grayscale. Similarly, the grayscale value corresponding to the data voltage to be applied to the second sub-pixel when the light is presented as the first brightness can also be obtained according to the second gamma curve as the second compensation grayscale. That is, it can be considered that: the brightness finally presented in the first display part is composed of multiple first brightnesses and multiple second brightnesses, and the brightness finally presented in the second display part is composed of multiple second brightnesses and multiple first brightnesses. Therefore, the brightness finally presented by the two display parts can be composed of the two elements of the first brightness and the second brightness. The constituent elements are the same, and the total brightness can also be close.

[0064] Furthermore, the number of the first sub-pixels in the first part is equal to the number of the second sub-pixels in the second part, and the number of the first sub-pixels in the second part is equal to the number of the second sub-pixels in the first part. As discussed above, it can be considered that the number of first sub-pixels presenting the first brightness in the first display part is equal to the number of second sub-pixels presenting the second compensation brightness (e.g., equal to the first brightness) in the second display part, and the number of first sub-pixels presenting the first compensation brightness (e.g., equal to the second brightness) in the first display part is equal to the number of second sub-pixels presenting the second brightness in the second display part, that is, the number of sub-pixels presenting the first brightness in the two display parts is the same, and the number of sub-pixels presenting the second brightness can also be the same, so that the brightness finally presented by the two display parts can be further equal.

[0065] Among them, Figure 4As shown, in the first display portion A1, the first part and the first sub-pixel include a plurality of first sub-pixel groups 101, the second part and the first sub-pixel include a plurality of second sub-pixel groups 102, and the plurality of first sub-pixel groups 101 and the plurality of second sub-pixel groups 102 are alternately arranged along a first direction D1; in the second display portion A2, the first part and the second sub-pixel include a plurality of third sub-pixel groups 103, the second part and the second sub-pixel include a plurality of fourth sub-pixel groups 104, and the plurality of third sub-pixel groups 103 and the plurality of fourth sub-pixel groups 104 are alternately arranged along the first direction.

[0066] Specific, combined Figure 1 As shown, a three-gate driving architecture is used as an example for explanation, that is, each row of sub-pixels can have the same color, and the colors of two adjacent rows of sub-pixels can be different. For example, in the first direction D1 (column direction), a row of blue sub-pixels B, a row of green sub-pixels G and a row of red sub-pixels R can be used as the minimum repeating unit and are repeatedly arranged in sequence. In the second direction D2 (row direction), multiple columns of sub-pixels can be arranged, and each column of sub-pixels can be used as a blue sub-pixel B, a green sub-pixel G and a color sub-pixel R as the minimum repeating unit and are repeatedly arranged in sequence.

[0067] Among them, taking the example that both the first sub-pixel and the second sub-pixel are green sub-pixels G, the first sub-pixel group 101 and the second sub-pixel group 102 in this embodiment can be the green sub-pixels G located in odd rows (for example, the 1st and 3rd rows in the first display part A1) and the green sub-pixels G located in even rows (for example, the 2nd and 4th rows in the first display part A1) among multiple rows of first sub-pixels (green sub-pixels G); similarly, the third sub-pixel group 103 and the fourth sub-pixel group 104 can be the green sub-pixels G located in odd rows (for example, the 1st and 3rd rows in the second display part A2) and the green sub-pixels G located in even rows (for example, the 2nd and 4th rows in the second display part A2) among multiple rows of second sub-pixels (green sub-pixels G).

[0068] Specifically, Figure 4 As shown, here a first original grayscale equal to 48 is used as an example for explanation. If the brightness presented when the grayscale value of the first sub-pixel in the first display portion A1 is equal to 70 can reach the same brightness (second brightness) as the brightness presented when the grayscale value of the second sub-pixel in the second display portion A2 is the first original grayscale (equal to 48), then the first compensated grayscale is equal to 70; similarly, if the brightness presented when the grayscale value of the second sub-pixel in the second display portion A2 is equal to 30 can reach the same brightness (first brightness) as the brightness presented when the grayscale value of the first sub-pixel in the first display portion A1 is the first original grayscale (equal to 48), then the second compensated grayscale is equal to 30.

[0069] It can be understood that in this way, the first sub-pixels presenting the first brightness and the second brightness in the first display part A1 can be evenly distributed, and the second sub-pixels presenting the first brightness and the second brightness in the second display part A2 can also be evenly distributed, thereby improving the uniformity of brightness in a smaller display area. Of course, the sub-pixels presenting the first brightness and the second brightness in the two display parts can also be evenly distributed in other arrangement methods, such as alternating distribution in the row direction, or alternating distribution in both the row direction and the column direction.

[0070] Specifically, combined with the above discussion, that is, Figure 5 As shown, step S1 may include but is not limited to the following steps.

[0071] S101, obtaining a first brightness of a first sub-pixel in a first display portion at a first original grayscale, and a second brightness of a second sub-pixel in a second display portion at the first original grayscale.

[0072] As discussed above, the first brightness and the second brightness may be determined according to a first gamma curve and a second gamma curve, respectively.

[0073] S102, determining a first compensation grayscale corresponding to the first sub-pixel at least according to the second brightness, and determining a second compensation grayscale corresponding to the second sub-pixel at least according to the first brightness.

[0074] As discussed above, the first compensation grayscale and the second compensation grayscale may also be determined according to the first gamma curve and the second gamma curve, respectively.

[0075] It should be noted that, in case 1, the execution subject of step S1 and the execution subjects of steps S101 to S102 can be the display panel itself and non-panel itself (for example, a compensation grayscale generating device), that is, it can be considered that before the panel leaves the factory, the display panel can be debugged by the compensation grayscale generating device using but not limited to steps S101 and S102 to determine the first compensation grayscale corresponding to the first original grayscale of the first sub-pixel and the second compensation grayscale corresponding to the first original grayscale of the second sub-pixel, and the first compensation grayscale and the second compensation grayscale are stored in the display panel. When the panel leaves the factory, the above compensation grayscale can be called as needed during the picture display process to execute step S2 (executed by the display panel); in case 1, the execution subject of step S1 and the execution subjects of steps S101 to S102 can be the display panel itself, that is, the display panel can determine and directly call the first compensation grayscale and the second compensation grayscale before or after leaving the factory.

[0076] In one embodiment, if Figures 6 to 8As shown, the display panel 100 includes a first source driver chip 001 and a second source driver chip 002, wherein Figure 6 and Figure 7 As shown, the first display portion A1 and the second display portion A2 are electrically connected to the first source driver chip 001 and the second source driver chip 002, respectively, or, as shown Figure 8 As shown, the first display portion A1 and the second display portion A2 are both electrically connected to the first source driver chip 001 , and the resistances between the first display portion A1 and the first source driver chip 001 are different.

[0077] Specifically, the display panel 100 may also include a main board 200 electrically connected to a plurality of source driver chips (including but not limited to a first source driver chip 001 and a second source driver chip 002). The main board may include but not limited to a power management module 201 and a timing control module 202. The power management module 201 may transmit a gamma voltage to each source driver chip, and transmit a corresponding image signal and an operating voltage to the timing control module 202. The timing control module 202 converts the image signal into a corresponding original data signal transmitted to each source driver chip under the drive of the operating voltage. Each source driver chip may generate a data signal loaded into a corresponding sub-pixel based on the gamma voltage and the corresponding original data signal.

[0078] It should be noted that, on the one hand, due to the difference in transmission distances between the power management module 201 and different source driver chips, for example, when the power management module 201 is arranged close to the middle of the display panel 100, it can be considered that the gamma voltage will first pass through the second source driver chip 002 and then pass through the first source driver chip 001. Taking into account the influence of the resistance of components, the data voltage acting on the first display part A1 electrically connected to the first source driver chip 001 is less than the data voltage acting on the second display part A2 electrically connected to the second source driver chip 002, which will cause uneven display of the picture; on the other hand, even for the first display part A1 and the second display part A2 electrically connected to the first source driver chip 001, due to the difference in transmission distances between the first source driver chip 001 and the two, the resistance between the two and the first source driver chip 001 is different, which will also cause uneven display of the picture.

[0079] It can be understood that in this embodiment, the first display part A1 and the second display part A2 in the above two scenarios are configured as above, which can improve the phenomenon of uneven screen display caused by at least one of the above two reasons. Figure 6 and Figure 7As shown, if the display panel 100 is divided into a fourth display part A4 and a third display part A3 which are symmetrical to the first display part A1 and the second display part A2, respectively, it can be considered that the transmission distance between the power management module 201 and the second display part A2 and the third display part A3 is equivalent, and it can be considered that there is almost no "dividing line" between the display screens of the two. Then, the above method for improving the "dividing line" between the first display part A1 and the second display part A2 can be referred to to improve the "dividing line" between the third display part A3 and the fourth display part A4. Similarly, if Figure 8 As shown, if the fourth display portion A4 and the third display portion A3 are symmetrical about the first display portion A1 and the second display portion A2 in the first direction D1, respectively, the above method can also be used to improve the "dividing line" between the third display portion A3 and the fourth display portion A4.

[0080] In one embodiment, if Fig. 9 As shown, the method may also include but is not limited to the following steps and a combination of the following steps.

[0081] S3, obtaining a third compensated grayscale corresponding to the first original grayscale of a third sub-pixel in a third display portion, and obtaining a fourth compensated grayscale corresponding to the first original grayscale of a fourth sub-pixel in a fourth display portion, wherein the color of the third sub-pixel and the color of the fourth sub-pixel are both the same as the color of the first sub-pixel, and the third compensated grayscale is determined at least based on a fourth brightness of the fourth sub-pixel at the first original grayscale, and the fourth compensated grayscale is determined at least based on a third brightness of the third sub-pixel at the first original grayscale.

[0082] Similarly, step S3 may also include but not include the following steps: dividing the display area of ​​the display panel into at least a third display portion and a fourth display portion, the third display portion includes a plurality of third sub-pixels, the fourth display portion includes a plurality of fourth sub-pixels, and the colors of the third sub-pixels and the fourth sub-pixels are both the same as the color of the first sub-pixel.

[0083] Specifically, the third display unit, the third sub-pixel, the fourth display unit and the fourth sub-pixel in the present embodiment can respectively refer to the relevant descriptions of the first display unit, the first sub-pixel, the second display unit and the second sub-pixel above. The description of obtaining the third compensation grayscale and the fourth compensation grayscale in the present embodiment can refer to the description of obtaining the first compensation grayscale and the second compensation grayscale in step S1 above.

[0084] S4, determining that the fifth sub-pixel in the fifth display portion corresponds to the fifth compensated grayscale of the first original grayscale based on the first compensated grayscale and the third compensated grayscale, and determining that the sixth sub-pixel in the sixth display portion corresponds to the sixth compensated grayscale of the first original grayscale based on the second compensated grayscale and the fourth compensated grayscale, the color of the fifth sub-pixel and the color of the sixth sub-pixel are both the same as the color of the first sub-pixel.

[0085] Similarly, step S3 may also include but not include the following steps: dividing the display area of ​​the display panel into at least a fifth display portion and a sixth display portion, the fifth display portion including a plurality of fifth sub-pixels, the sixth display portion including a plurality of sixth sub-pixels, and the colors of the fifth sub-pixels and the sixth sub-pixels are both the same as the color of the first sub-pixel.

[0086] Among them, Fig.10 As shown, the first display portion A1, the third display portion A3 and the fifth display portion A5 are all electrically connected to the first source driver chip 001, and the first resistor, the third resistor and the fifth resistor are respectively provided between the three and the first source driver chip 001, the second display portion A2, the fourth display portion A4 and the sixth display portion A6 are all electrically connected to the second source driver chip 002, and the second resistor, the fourth resistor and the sixth resistor are respectively provided between the three and the second source driver chip 002, the first resistor is equal to the second resistor, the third resistor is equal to the fourth resistor, and the fifth resistor is equal to the sixth resistor, based on Fig.10 According to the connection structure shown, it can be considered that the first display part A1, the third display part A3 and the fifth display part A5 are arranged in the same row (the relative positions of the three are not limited), the second display part A2, the fourth display part A4 and the sixth display part A6 are arranged in the same row (the relative positions of the three are the same as the relative positions of the previous three), the first display part A1 and the second display part A2 are arranged in the same row, the fifth display part A5 and the sixth display part A6 are arranged in the same row, and the third display part A3 and the fourth display part A4 are arranged in the same row;

[0087] Or, if Fig.11As shown, the first display portion A1 and the second display portion A2 are both electrically connected to the first source driver chip 001, and the first resistor and the second resistor are respectively provided between the first source driver chip 001 and the third display portion A3 and the fourth display portion A4 are both electrically connected to the second source driver chip 002, and the third resistor and the fourth resistor are respectively provided between the second source driver chip 002 and the fifth source driver chip 003 and the sixth resistor are respectively provided between the third source driver chip 003 and the third source driver chip 003, and the first resistor, the third resistor and the fifth resistor are equal, and the second resistor, the fourth resistor and the sixth resistor are equal. Fig.11 According to the connection structure shown, it can be considered that the first display part A1, the third display part A3 and the fifth display part A5 are arranged in the same row (the relative positions of the three are not limited), the second display part A2, the fourth display part A4 and the sixth display part A6 are arranged in the same row (the relative positions of the three are the same as the previous three relative positions), the first display part A1 and the second display part A2 are arranged in the same column, the fifth display part A5 and the sixth display part A6 are arranged in the same column, and the third display part A3 and the fourth display part A4 are arranged in the same column.

[0088] Specifically, the resistance value mentioned in the present embodiment can be equivalent to describing the length of the transmission path between the sub-pixel and the corresponding source driver chip. The present embodiment can determine the fifth compensation grayscale and the sixth compensation grayscale by but not limited to linear interpolation. For example, according to the difference between the first compensation grayscale and the third compensation grayscale and the relative positions of the fifth sub-pixel and the first sub-pixel and the third sub-pixel, the fifth compensation grayscale corresponding to the fifth sub-pixel can be determined. The sixth compensation grayscale can be determined similarly.

[0089] S5, controlling the fifth subpixel in the first part and the sixth subpixel in the first part to emit light at the first original grayscale, controlling the fifth subpixel in the second part to emit light at the fifth compensated grayscale, and controlling the sixth subpixel in the second part to emit light at the sixth compensated grayscale.

[0090] Similarly, reference can be made to step S2 to control the light-emitting mode of the third sub-pixel in the third display part A3 and the fourth sub-pixel in the fourth display part A4, and the light-emitting mode of the fifth sub-pixel in the fifth display part A5 and the sixth sub-pixel in the sixth display part A6 are also controlled accordingly as in step S2.

[0091] Similarly, in this embodiment, the difference between the display screen of the third display part A3 and the display screen of the fourth display part A4 can be reduced, and the difference between the display screen of the fifth display part A5 and the display screen of the sixth display part A6 can be reduced. Therefore, this embodiment can further effectively reduce the brightness difference of the display screen in different areas of the display panel, and improve the uniformity of the overall display screen.

[0092] In one embodiment, if Fig.12 As shown, the method may also include but is not limited to the following steps and combinations of the following steps.

[0093] S6, determining a third compensated grayscale corresponding to the first original grayscale for a third sub-pixel in a third display portion according to the first compensated grayscale and the second compensated grayscale.

[0094] Among them, Fig.13 As shown, the first display portion A1, the second display portion A2 and the third display portion A3 are all electrically connected to the first source driver chip 001. Fig.13 According to the connection structure shown, it can be considered that the first display part A1, the second display part A2 and the third display part A3 are arranged in the same column;

[0095] Or, if Fig.14 As shown, the three are electrically connected to the second source driver chip 002, the third source driver chip 003 and the fourth source driver chip 004 respectively (here, the first source driver chip 001 to the fourth source driver chip 004 are provided as an example), and the resistance between the three and the second source driver chip 002, the third source driver chip 003 and the fourth source driver chip 004 is equal (because the second source driver chip 002 to the fourth source driver chip 004 are arranged close to the center of the display panel 100, the distance between the three in the horizontal direction can be ignored here), based on Fig.14 According to the connection structure shown, it can be considered that the first display part A1, the second display part A2 and the third display part A3 are arranged in the same row.

[0096] Specifically, as discussed above, the first compensated grayscale is determined at least based on the second brightness of the second sub-pixel at the first original grayscale, and the second compensated grayscale is determined at least based on the first brightness of the first sub-pixel at the first original grayscale. Further, it can be considered that the brightness of the first sub-pixel at the first compensated grayscale is equal to the second brightness, and the brightness of the second sub-pixel at the second compensated grayscale is equal to the first brightness; similarly, the third compensated grayscale can be determined by but not limited to linear interpolation, for example, based on the difference between the first compensated grayscale and the second compensated grayscale and the relative positions of the third sub-pixel, the first sub-pixel and the second sub-pixel, to determine the third grayscale compensation corresponding to the third sub-pixel.

[0097] S7, controlling the third sub-pixel in the first part to emit light at the first original grayscale, and controlling the third sub-pixel in the second part to emit light at the third compensated grayscale.

[0098] It can be understood that, in combination with the above discussion, the total brightness of both the first display part A1 and the second display part A2 is composed of multiple first brightnesses and multiple second brightnesses, and all sub-pixels of the color will eventually present a brightness value between the first brightness and the second brightness, and the brightness of the two can be equal. It can be considered that the third sub-pixel in this embodiment emits light at the first original grayscale and the third compensated grayscale and presents the third brightness and the fourth brightness respectively. For example, when the third display part A3 is located between the first display part A1 and the second display part A2, it can be considered that the third compensated grayscale is between the first compensated grayscale and the second compensated grayscale, and the third brightness and the fourth brightness (both of which can also be equal) are between the first brightness and the second brightness, and the total brightness of the third display part A3 can be close to the total brightness of the first display part A1 and the total brightness of the second display part A2.

[0099] In one embodiment, if Fig.15 As shown, the method may also include but is not limited to the following steps and combinations of the following steps.

[0100] S8, obtaining a third compensated grayscale corresponding to the second original grayscale of the first sub-pixel, and obtaining a fourth compensated grayscale corresponding to the second original grayscale of the second sub-pixel, the three compensated grayscales being determined at least based on a fourth brightness of the second sub-pixel at the second original grayscale, and the fourth compensated grayscale being determined at least based on a third brightness of the first sub-pixel at the second original grayscale.

[0101] The second original grayscale may not be equal to the first original grayscale. Similarly, referring to the discussion of step S1, this embodiment can obtain the third compensated grayscale and the fourth compensated grayscale of the first sub-pixel and the second sub-pixel corresponding to the second original grayscale respectively.

[0102] S9, determining that the first sub-pixel corresponds to a fifth compensated grayscale of the third original grayscale according to the first compensated grayscale and the third compensated grayscale, and determining that the second sub-pixel corresponds to a sixth compensated grayscale of the third original grayscale according to the second compensated grayscale and the fourth compensated grayscale.

[0103] The third original grayscale may not be equal to the first original grayscale and the second original grayscale. Similarly, in this embodiment, the fifth compensation grayscale and the sixth compensation grayscale may be determined by, but not limited to, linear interpolation, for example, according to the difference between the first compensation grayscale and the third compensation grayscale and the relative positions of the third original grayscale, the first original grayscale and the second original grayscale, to determine the fifth compensation grayscale of the first sub-pixel corresponding to the third original grayscale, and the sixth compensation grayscale may be determined similarly.

[0104] In one embodiment, after step S2, the following steps may be included but not limited to: controlling the first part of the third sub-pixels in the first display unit and the first part of the fourth sub-pixels in the second display unit to emit light at the first original grayscale, and controlling the second part of the third sub-pixels in the first display unit to emit light at the first compensated grayscale, and controlling the second part of the fourth sub-pixels in the second display unit to emit light at the second compensated grayscale, the color of the third sub-pixel is the same as the color of the fourth sub-pixel, and both colors are different from the color of the first sub-pixel.

[0105] That is, the first display portion further includes a plurality of third sub-pixels, the second display portion further includes a plurality of fourth sub-pixels, the colors of the third sub-pixels are the same as the colors of the fourth sub-pixels, and both colors are different from the color of the first sub-pixel.

[0106] Specifically, in this embodiment, the first sub-pixel and the second sub-pixel of the same color correspond to the first compensated grayscale and the second compensated grayscale of the first original grayscale respectively, and the third sub-pixel and the fourth sub-pixel of the same color correspond to the two compensated grayscales of the first original grayscale respectively, so as to reduce the whole amount of calculation. Wherein the first sub-pixel and the second sub-pixel can both be green, that is, the sub-pixel of the color that mainly causes the "dividing line" in the prior art, then the corresponding compensation data can also be applied to sub-pixels of other colors.

[0107] The present invention also provides a display panel for executing any of the display panel compensation methods described above.

[0108] The present invention also provides a compensation grayscale generating device, which is used to generate the first compensation grayscale and the second compensation grayscale as described above.

[0109] The present invention provides a display panel and a compensation method thereof, and a device for generating a compensated grayscale. By obtaining a first compensated grayscale corresponding to a first original grayscale of a first sub-pixel in a first display portion, and obtaining a second compensated grayscale corresponding to the first original grayscale of a second sub-pixel in a second display portion, the color of the first sub-pixel is the same as the color of the second sub-pixel, the first compensated grayscale is determined at least according to the second brightness of the second sub-pixel at the first original grayscale, and the second compensated grayscale is determined at least according to the first brightness of the first sub-pixel at the first original grayscale; the first sub-pixel in the first part and the second sub-pixel in the first part are controlled to emit light at the first original grayscale, the first sub-pixel in the second part is controlled to emit light at the first compensated grayscale, and the second sub-pixel in the second part is controlled to emit light at the second compensated grayscale, so as to effectively reduce the brightness difference of the display screen in different areas of the display panel and improve the uniformity of the overall display screen.
