With the rapid development of electronic devices, users have higher and higher requirements for the display effect of the electronic devices.
In the pixel arrangement structure provided by the related art, the pixel arrangement structure includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, the two red sub-pixels and the two blue sub-pixels are alternately arranged around the same green sub-pixel, and since the area of the blue sub-pixel is larger than that of the red sub-pixel, the distance between the green sub-pixel and the two red sub-pixels around the green sub-pixel is unequal, and the distance between the green sub-pixel and the red sub-pixel is unequal to that between the blue sub-pixels, which results in a large loss of the pixel arrangement structure in terms of aperture ratio, the pixel aperture ratio of the pixel arrangement structure is small, and the display effect is poor.
The present application is proposed to solve the above-mentioned technical problems. For a better understanding of the present application, an electrical pixel arrangement structure, a mask assembly, a display panel, and an electronic device according to embodiments of the present application are described in detail below with reference to fig. 1 to 9.

The first direction and the second direction are arranged in various ways, and the first direction and the second direction can be intersected and arranged at any preset angle. In some alternative embodiments, the included angle between the first direction and the second direction is 90 degrees, such as the X-axis (first direction) and the Y-axis (second direction) shown in fig. 1, so that each of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 can be arranged horizontally and vertically along the horizontal and vertical directions, and the structure is simple and the manufacturing is convenient.
In the pixel arrangement structure of the present application, the pixel arrangement structure includes a first sub-pixel 110, a second sub-pixel 120, and a third sub-pixel 130, and when the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 form a display unit 200 for emitting white light, the first sub-pixel 110 and the second sub-pixel 120 can be shared by two adjacent display units 200, so that the pixel density of the pixel arrangement can be increased, and the display effect of the pixel arrangement structure can be improved. The three sub-pixels forming one display unit 200 are indicated by the triangles of chain lines in fig. 1, and the triangles formed by chain lines do not form structural limitations on the pixel arrangement structure of the present application.

The third sub-pixel 130 includes a body portion 131 and a first extension portion 132, and the first extension portion 132 extends and forms toward the space between the first sub-pixel 110 and the second sub-pixel 120 at the two ends of the long side 310, so that the distance between the third sub-pixel 130 and the first sub-pixel 110 and the second sub-pixel 120 at the two ends of the long side 310 can be reduced, the distance between the third sub-pixel 130 and the sub-pixel at the two ends of the short side 320 is closer to the distance between the third sub-pixel 130 and the sub-pixel at the two ends of the long side 310, the display effect is more uniform, and the display effect of the pixel arrangement structure can be further improved.
In some alternative embodiments, please continue to refer to fig. 1, two adjacent virtual quadrangles 300 in the second direction share one side 330, the long sides 310 and the short sides 320 are alternately distributed along the second direction, and the first extending portions 132 of two adjacent third sub-pixels 130 in the second direction are formed to extend in opposite directions, so that the first extending portions 132 of two adjacent third sub-pixels 130 in the second direction can both be formed to extend between the first sub-pixel 110 and the second sub-pixel 120 at two ends of the long side 310.
Alternatively, two virtual quadrangles 300 adjacent in the first direction share one long side 310 or one short side 320.
Alternatively, the long side 310 and the short side 320 are parallel to each other, i.e. the virtual quadrangle 300 is a trapezoid. Two adjacent columns of the first sub-pixels 110 and the second sub-pixels 120 in the first direction can be parallel to each other, the pixel arrangement structure is more regular, and the sub-pixels are more uniformly distributed.
Optionally, the centers of the long side 310 and the short side 320 of the same virtual quadrangle 300 in the first direction are aligned, that is, the virtual quadrangle 300 is an isosceles trapezoid, so that the arrangement of the two first sub-pixels 110 and the two second sub-pixels 120 on the peripheral side of the third sub-pixel 130 is more uniform, and the display effect of the pixel arrangement structure is more uniform.

Optionally, the area of the second sub-pixel 120 is larger than the area of the first sub-pixel 110, and the area of the first sub-pixel 110 is larger than the area of the third sub-pixel 130. The number of the third sub-pixels 130 is larger, and the third sub-pixels 130 are located in the virtual quadrangle 300, so the third sub-pixels 130 can be set smaller to reduce the distance between the first sub-pixels 110 and the second sub-pixels 120. The larger area of the blue sub-pixel can improve the lifetime of the blue sub-pixel.
With continued reference to fig. 1, in some alternative embodiments, two third sub-pixels 130 adjacent to each other along the first direction are symmetrically distributed about the first axis P extending along the second direction. The first extension portions 132 of two third sub-pixels 130 adjacent to each other in the first direction are disposed opposite to each other, that is, a portion of the first extension portions 132 of two third sub-pixels 130 adjacent to each other in the first direction are formed to extend toward a direction close to each other, and another portion of the first extension portions 132 of two third sub-pixels 130 adjacent to each other in the first direction are formed to extend toward a direction away from each other. The position of the first axis P is indicated in fig. 1 by a dash-dot line, and the first axis P does not form a structural limitation to the pixel arrangement of the present application.
Optionally, when the third sub-pixels 130 are manufactured, two third sub-pixels 130 adjacent to each other in the first direction and having the first extension portions 132 opposite to each other share one mask opening, so as to simplify the manufacturing of the third sub-pixels 130 and improve the aperture ratio of the third sub-pixels 130. The two third sub-pixels 130 opposite to the first extension 132 refer to: the first extension portions 132 of the two third sub-pixels 130 adjacent to each other in the first direction are formed to extend toward the direction close to each other.

First interval H1The second distance H is a minimum distance between edges of two body portions 131 adjacent to each other in the second direction2Is the minimum distance between two first extension portions 132 adjacent in the first direction.
In these alternative embodiments, the first pitch H1And a second pitch H2The distances among the three third sub-pixels 130 which are close to each other are equal, so that the comfort level of human eye perception and the pixel arrangement junction can be further improvedAnd (5) displaying effect of the structure.
Optionally, the first axis P passes through the center of the first sub-pixel 110 and/or the second sub-pixel 120 in the first direction.

In some alternative embodiments, with reference to fig. 1, the body portions 131 of the third sub-pixels 130 arranged along the second direction are aligned along the second direction, so that the body portions 131 of the third sub-pixels 130 arranged along the second direction are closer to each other. When the third sub-pixels 130 are prepared, the plurality of third sub-pixels 130 arranged along the second direction can share the opening of the same mask plate for vapor deposition molding, so that the preparation of the third sub-pixels 130 can be simplified, and the opening ratio of the third sub-pixels 130 can be improved.
