With reference to fig. 4, the vertical projection of each hollow-out portion 111 on the plane of the array substrate 10 covers the vertical projection of the two light-emitting units 12 on the plane of the array substrate 10, so that the area of each hollow-out portion 111 is large, the hollow-out portion 111 has a large influence on the areas of the touch electrode blocks 11 on the left and right portions of the pressing area 41, the difference between the areas of the touch electrode blocks 11 on the left and right portions of the pressing area 41 is increased, the difference between the signal amounts on the left and right portions of the pressing area 41 is large, and the touch accuracy and linearity are low.
With reference to fig. 3, in another display panel provided in the embodiment of the present invention, the vertical projection of each hollow portion 111 on the plane of the array substrate 10 only covers the vertical projection of one sub-pixel 121 on the plane of the array substrate 10, so that the area of the hollow portion 111 is greatly reduced, the distribution of the hollow portion 111 is more dispersed, the influence of the hollow portion 111 on the areas of the left portion and the right portion of the touch electrode block 11 of the pressing region 41 is reduced, the difference between the signal amounts of the left portion and the right portion of the pressing region 41 is reduced, the detected actual coordinate is closer to the theoretical coordinate, and the touch accuracy and the linearity are improved.
In the display panel provided by the embodiment of the invention, the touch function is realized by arranging the plurality of touch electrode blocks 11 on the array substrate 10; by arranging the vertical projection of each hollow-out part 111 on the plane of the array substrate 10 to cover the vertical projection of at least one sub-pixel 121 on the plane of the array substrate 10, the sub-pixel 121 is prevented from being shielded by the touch electrode block 11 to influence the display, and the display effect is improved. Through setting up dislocation along first direction X of two at least adjacent fretwork portion rows 21, reduce the difference between the area of the touch electrode piece 11 of the touch point along the different sides of first direction X, reduced the semaphore difference of pressing the regional 41 different lateral parts for the actual coordinate that detects more is close theoretical coordinate, has improved touch-control precision and linearity. In addition, the vertical projection of each hollow-out part 111 on the plane of the array substrate 10 only covers the vertical projection of one sub-pixel 121 on the plane of the array substrate 10, so that the area of the hollow-out part 111 is greatly reduced, the distribution of the hollow-out parts 111 is more dispersed, the influence of the hollow-out part 111 on the areas of the touch electrode blocks 11 on different sides of the touch point is reduced, the difference between the areas of the touch electrode blocks 11 on different sides of the touch point is reduced, the difference of signal quantities of different side parts of the pressing area 41 is reduced, the detected actual coordinate is closer to the theoretical coordinate, and the touch accuracy and the linearity are improved.

With continued reference to fig. 2, optionally, the space between two neighboring hollow-out portions 111 in the same hollow-out portion row 21 is D3, where (1/3) × D2 is no less than D1 is no less than (2/3) × D2, or (1/5) × (D2+ D3) is no less than D1 is no less than (2/5) × (D2+ D3).
As shown in fig. 2, if the offset distance D1 is too small, the area difference between the touch electrode blocks 11 on the left and right sides of the touch point cannot be reduced significantly, so that the effect of improving the touch accuracy and linearity cannot be achieved; for example, as shown in fig. 2, if the offset distance D1 is too large, the effect of improving the touch accuracy and the linearity is not achieved, and if the offset distance D1 of the even number of the hollow-out portion rows 21 is too large, the even number of the hollow-out portion rows 21 is offset to the left side by a smaller distance than the odd number of the hollow-out portion rows 21, so that the area difference of the touch electrode blocks 11 on the left and right sides of the touch point cannot be reduced obviously, and the effect of improving the touch accuracy and the linearity is not achieved. Therefore, the display panel provided by the embodiment of the invention meets the requirements that (1/3) × D2 is not less than D1 is not more than (2/3) × D2, or (1/5) × (D2+ D3) is not less than D1 is not more than (2/5) × (D2+ D3) by setting the misplaced distance D1, so as to ensure that the effects of improving the touch accuracy and the linearity are achieved.

With reference to fig. 4, none of the hollow-out rows 21 is arranged in a staggered manner, when the display panel encounters a small signal amount touch, such as a passive pen, a glove, a nail cover, and a floating touch, as shown in fig. 4, when it is assumed that a touch point is operated from left to right, an obtained theoretical coordinate should be a straight line from left to right, but due to the hollow-out portion 111 arranged on the touch electrode block 11, the signal amounts on the left side and the right side of the touch point are asymmetric and unstable, which results in low touch accuracy and linearity, and causes a large deviation between the theoretical coordinate and an actual coordinate.
Specifically, as shown in FIG. 4, toThe length D2 of the hollow-out portions 111 along the first direction X is 80 μm, the length of the hollow-out portions 111 along the second direction Y is the same as D2, the distance D3 between two adjacent hollow-out portions 111 is 70 μm, for example, the area of the touch electrode block 11 at the lower part of the pressing region 42 at a certain time is 70 μm2The area of the touch electrode block 11 at the upper portion of the pressing region 42 is 70 × 80+70+80 μm2Then, the ratio of the area of the touch electrode block 11 at the lower portion of the pressing region 42 to the area of the touch electrode block 11 at the upper portion of the pressing region 42 reaches 7: 23, the difference in the signal amount between the lower portion and the upper portion of the pressed region 42 is large, and the detected actual coordinates are greatly shifted to the upper side compared to the theoretical coordinates.
With reference to fig. 5, in the display panel provided in the embodiment of the invention, at least two adjacent hollow-out rows 22 in the touch electrode block 11 are arranged to be staggered along the second direction Y, taking the length D2 of the hollow-out 111 along the first direction X as 80 μm, the length of the hollow-out 111 along the second direction Y as the same as D2, the distance D3 between two adjacent hollow-out 111 as 70 μm, and the staggered distance D1 along the second direction Y as 40 μm as an example, the area of the touch electrode block 11 at the lower side of the pressing region 42 at a certain time is (70 × 70) + (80 × 30) μm2The area of the touch electrode block 11 at the upper portion of the pressing region 42 is 70 × 70+80) + (80 × 30) μm2Then, the ratio of the area of the touch electrode block 11 at the left side portion of the pressing region 42 to the area of the touch electrode block 11 at the right side portion of the pressing region 42 is 73: 129, compared with the display panel shown in fig. 4, the area of the touch electrode block 11 at the lower part of the pressing region 42 is closer to the area of the touch electrode block 11 at the upper part of the pressing region 42, so that the difference of the signal quantity at the lower part and the upper part of the pressing region 42 is reduced, the detected actual coordinate is closer to the theoretical coordinate, and the touch accuracy and the linearity are improved.
In addition, the touch precision and linearity are improved by arranging at least two adjacent hollow part rows 22 along the second direction Y in a staggered manner, and compared with the display panel shown in fig. 4, the number of the light emitting units 12 in a unit area is basically unchanged, so that the display brightness and the chromaticity of the display panel are not affected, and the display effect of the display panel is ensured.
It should be noted that the second direction Y is not limited to the column direction in fig. 5, and those skilled in the art can arbitrarily set the second direction Y according to actual requirements, for example, the second direction Y is set as a row direction, which is not limited in the embodiment of the present invention.

As shown in fig. 5, if the offset distance D4 is too small, the area difference between the touch electrode blocks 11 on the upper and lower sides of the touch point cannot be reduced significantly, so that the effect of improving the touch accuracy and linearity cannot be achieved; for example, as shown in fig. 5, if the distance D4 that the even number of hollow-out portion rows 22 are staggered upward from the odd number of hollow-out portion rows 22 is too large, it is equivalent to that the even number of hollow-out portion rows 22 are staggered downward from the odd number of hollow-out portion rows 22 by a small distance, so that the difference in area between the touch electrode blocks 11 on the upper and lower sides of the touch point cannot be reduced significantly, and the effect of improving the touch accuracy and linearity cannot be achieved. Therefore, the display panel provided by the embodiment of the invention meets the requirements that (1/3) × D5 is not less than D4 is not more than (2/3) × D5, or (1/5) × (D5+ D6) is not less than D4 is not more than (2/5) × (D5+ D6) by setting the misplaced distance D4, so as to ensure that the effects of improving the touch accuracy and the linearity are achieved.
