Please refer toFIG.1, which is a schematic diagram of a first structure of a display panel10according to an embodiment of the present disclosure. The present disclosure provides a display panel10. The display panel10comprises a plurality of pixel units11arranged in an array and a plurality of data lines30. Each of the pixel units11comprises three sub-pixels11awith different colors. The sub-pixels11aare arranged between adjacent data lines30. Each of the sub-pixels11acorresponds to a high grayscale H or a low grayscale (L1, L2, or L3). The sub-pixels11ain a same column have a same color. The pixel units11in two adjacent rows in two adjacent columns form a grayscale combined pixel20. The grayscale combined pixel20comprises three sub-pixels11aof different colors corresponding to the high grayscale H and nine sub-pixels11acorresponding to the low grayscale (L1, L2, and L3).

It should be noted that the display panel10of the present disclosure can be used in a display panel. Based on the display panel10of the present disclosure, viewing angles of the display panel during display are increased. Specifically, the pixel units11are arranged in a matrix array. Each column of the sub-pixels11ais arranged between two adjacent data lines30in a horizontal direction. The sub-pixels11ain a same column have a same color. Specifically, one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3) in the grayscale combined pixel20replace one sub-pixel11aof an original grayscale. The grayscale combined pixel20comprises three sub-pixels11aof different colors corresponding to the high grayscale H and nine sub-pixels11acorresponding to the low grayscale (L1, L2, and L3), so one grayscale combined pixel20can replace three sub-pixels11aof the original grayscales. One sub-pixel11aof the original grayscale is replaced with one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3), which further increases a difference between the high grayscale H and the low grayscales (L1, L2, and L3). Therefore, viewing angles of the display panel10are further improved.

Please refer toFIG.2, which is a schematic diagram of a second structure of a display panel10according to an embodiment of the present disclosure. The grayscale combined pixel20comprises three sub-grayscale combined pixels20aarranged in sequence. Each of the sub-grayscale combined pixels20acomprises one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3).

It should be noted that one sub-grayscale combined pixel20areplaces one sub-pixel11aof the original grayscale. In some embodiments, as shown inFIG.3, the grayscale combined pixel20comprises a first sub-grayscale combined pixel21, a second sub-grayscale combined pixel22, and a third sub-grayscale combined pixel23. The first sub-grayscale combined pixel21, the second sub-grayscale combined pixel22, and the third sub-grayscale combined pixel23are arranged in order from left to right. Each of the first sub-grayscale combined pixel21, the second sub-grayscale combined pixel22, and the third sub-grayscale combined pixel23comprises one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3). One sub-grayscale combined pixel20areplaces one sub-pixel11aof the original grayscale, which further increases the difference between the high grayscale H and the low grayscales (L1, L2, and L3). Therefore, the viewing angles of the display panel10are further improved.

In addition, an arrangement order of the one sub-pixel11acorresponding to the high grayscale H and the three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3) in the sub-grayscale combined pixel20amay be adjusted freely, which will not be described in details in the embodiments of the present disclosure.

Please refer toFIG.4, which is a schematic diagram of a fourth structure of a display panel10according to an embodiment of the present disclosure. The display panel10of this embodiment differs from that of the foregoing embodiments in that in the foregoing embodiments, the pixel units11in two adjacent rows in two adjacent columns are cyclically arranged, while in this embodiment, the pixel units11in four adjacent rows in two adjacent columns are cyclically arranged. Furthermore, in this embodiment, four adjacent sub-pixels in the same column from one grayscale combined pixel20and comprise one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3).

It should be noted that this embodiment not only needs to ensure that the sub-pixels11ain two adjacent rows in two adjacent columns comprise one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3), but also needs to ensure that four adjacent sub-pixels in the same column comprise one sub-pixel11acorresponding to the high grayscale H and the three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3). This embodiment uses such a pixel arrangement structure to make an arrangement of the sub-pixels11amore balanced, which is beneficial to improve quality of the display panel10.

Specifically, the grayscale combined pixel20comprises one sub-pixel11acorresponding to the high grayscale H and three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3).

Please refer toFIG.5, which is a schematic diagram of a fifth structure of a display panel10according to an embodiment of the present disclosure. When the sub-pixel11ain a first row in a first column in the display panel10corresponds to the high grayscale H, the sub-pixel11ain the first row in the first column has a negative polarity. When the sub-pixel11ain the first row in the first column corresponds to the high grayscale H, avoid the sub-pixel11ain the first row in the first column from having a positive polarity, which improves a display effect of the display panel10.

In another embodiment, if the sub-pixel11ain the first row in the first column in the display panel10corresponds to the high grayscale H, and the sub-pixel11ain the first row in the first column has the positive polarity, grayscale values of the three low grayscales (L1, L2, and L3) are increased. By increasing the grayscale values of the three low grayscales (L1, L2, and L3), influence of “the sub-pixel11ain the first row in the first column in the display panel10corresponds to the high grayscale H” and “the sub-pixel11ain the first row in the first column has the positive polarity” on the display effect of the display panel10is eliminated.

The sub-pixels11acorresponding to the high grayscale H in the grayscale combined pixels20in adjacent columns are located in different rows. Staggering the sub-pixels11acorresponding to the high grayscale H in the grayscale combined pixels20in adjacent columns prevents uneven display of the display panel10. This structure improves display quality of the display panel10.

Please refer toFIG.6, which is a schematic diagram of a sixth structure of a display panel10according to an embodiment of the present disclosure. The grayscale combined pixel20comprises a first pixel unit111a,a second pixel unit111b,a third pixel unit111c,and a fourth pixel unit111d.The first pixel unit111aand the second pixel unit111bare located in a row in the grayscale combined pixel20. The third pixel unit111cand the fourth pixel unit111dare located in the other row of the grayscale combined pixel20. The first pixel unit111acomprises three sub-pixels11acorresponding to the high grayscale H. Each of the second pixel unit111b, the third pixel unit111c, and the fourth pixel111dcomprises three sub-pixels11acorresponding to the low grayscales (L1, L2, and L3). The second pixel unit111bcomprises three sub-pixels11acorresponding to a first low grayscale L1. The third pixel unit111ccomprises three sub-pixels11acorresponding to a second low grayscale L2. The fourth pixel unit111dcomprises three sub-pixels11acorresponding to a third low grayscale L3.

It should be noted that grayscale values of the three sub-pixels11ain the first pixel unit111aare same, grayscale values of the three sub-pixels11ain the second pixel unit111bare same, grayscale values of the three sub-pixels11ain the third pixel unit111care same, and grayscale values of the three sub-pixels11ain the fourth pixel unit111dare same. The grayscales corresponding to the sub-pixels11ain the first pixel unit111a,the second pixel unit111b,the third pixel unit111c,and the fourth pixel unit111dmay be exchanged. For example, the first pixel unit111acomprises three sub-pixels11acorresponding to the first low grayscale L1, the second pixel unit111bcomprises three sub-pixels11acorresponding to the second low grayscale L2, the third pixel unit111ccomprises three sub-pixels11acorresponding to the third low grayscale L3, and the fourth pixel unit111dcomprises three sub-pixels11acorresponding to the high grayscale H. In the display panel10of this embodiment, the original grayscales of all the sub-pixels11ain one pixel unit11may be replaced to further increase the difference between the high grayscale H and the low grayscales (L1, L2, and L3), thereby further improving the viewing angles of the display panel10.

A grayscale value of the high grayscale H is greater than grayscale values of the low grayscales (L1, L2, and L3). The first low grayscale L1, the second low grayscale L2, and the third low grayscale L3 have different grayscale values.

It should be noted that the grayscale value of the first low grayscale L1 may be greater than the grayscale value of the second low grayscale L2, and the grayscale value of the second low grayscale L2 may be greater than the grayscale value of the third low grayscale L3. In some embodiments, a relationship between the grayscale values of the first low grayscale L1, the second low grayscale L2, and the third low grayscale L3 may be adjusted. In other embodiments, the first low grayscale L1, the second low grayscale L2, and the third low grayscale L3 may have a same grayscale value.

Please refer toFIG.7, which is a schematic diagram of a seventh structure of a display panel10according to an embodiment of the present disclosure. Each of the pixel units11comprises a red sub-pixel111, a green sub-pixel112, and a blue sub-pixel113that are sequentially arranged along a horizontal direction.

It should be noted that arrangement positions of the red sub-pixel111, the green sub-pixel112, and the blue sub-pixel113may also be changed. For example, the blue sub-pixel113, the green sub-pixel112, and the red sub-pixel111are arranged in order from left to right in the horizontal direction.

The high grayscale H and the low grayscales (L1, L2, and L3) corresponding to the sub-pixels11aare obtained by looking up values corresponding to the original grayscales of the sub-pixels11athrough a wide viewing angle algorithm.

It should be noted that the wide viewing angle algorithm preprocesses the data lines30without changing original display brightness. For example, taking 128 grayscale display of the red sub-pixel111as an example, find one high grayscale H and three low grayscales (L1, L2, and L3) of the red sub-pixel111on a front-view gamma curve, and an average brightness of the one high grayscale H and the three low grayscales (L1, L2, and L3) of the red sub-pixel111is equal to a brightness of four original red sub-pixels111with 128 grayscale. In this way, the one high grayscale H and the three low grayscales (L1, L2, and L3) of the red sub-pixel111are obtained. Of course, one high grayscale H and three low grayscales (L1, L2, and L3) of each of the green sub-pixel112and the blue sub-pixel113can be found by a same method.

Please refer toFIG.8, which is an effect diagram of gamma curves of a display panel according to an embodiment of the present disclosure. In the prior art, sub-pixels are processed by the wide viewing angle algorithm to obtain a gamma curve of high grayscale 1H and low grayscale L. In this disclosure, one original low grayscale L is replaced with three low grayscales (L1, L2, and L3), which further increases the difference between the high grayscale H and the low grayscales (L1, L2, and L3). Therefore, the viewing angles of the display panel10are further improved. Please refer toFIG.9, which is a comparison diagram of a gamma curve of a display panel according to an embodiment of the present disclosure and gamma curves of other display panels. A target curve is an effect curve of a target side view. The closer to the target curve, the better the display effect. A VacHHLL curve is a curve obtained by looking up VAC values of the display panel10. An original side view line is a curve obtained without looking up VAC values.

The sub-pixels11ain adjacent rows have opposite polarities, and the sub-pixels11ain adjacent columns have opposite polarities.

The present disclosure provides a display panel10comprising a plurality of pixel units11arranged in an array and a plurality of data lines30. Each of the pixel units11comprises three sub-pixels11awith different colors. The sub-pixels11aare arranged between adjacent data lines30. Each of the sub-pixels11acorresponds to a high grayscale H or a low grayscale (L1, L2, or L3). The sub-pixels11ain a same column have a same color. The pixel units11in two adjacent rows in two adjacent columns form a grayscale combined pixel20. The grayscale combined pixel20comprises three sub-pixels11aof different colors corresponding to the high grayscale H and nine sub-pixels11acorresponding to the low grayscales (L1, L2, or L3). In the present disclosure, one high grayscale H and three low grayscales (L1, L2, or L3) replace a grayscale of one sub-pixel11ato further increase the difference between the high grayscale H and the low grayscales (L1, L2, or L3), thereby further improving the viewing angles of the display panel10.
