Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present invention in its various embodiments. However, the technical solution claimed in the present invention can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a pixel structure, and a specific structure thereof is as shown in fig. 1(a), including:
a plurality of first pixel units 1 and a plurality of second pixel units 2, each first pixel unit 1 including a first sub-pixel 11, each second pixel unit 2 including a second sub-pixel 21 having the same color as the first sub-pixel 11; the first pixel units 1 and the second pixel units 2 are alternately arranged along a first direction X, the first sub-pixels 11 and the second sub-pixels 21 are sequentially arranged in the first direction X, and the shape of the first sub-pixels 11 and the shape of the adjacent second sub-pixels 21 are spliced into a first graph 3 with a first common edge 30; the first pixel units 1 and the second pixel units 2 are alternately arranged along a second direction Z, and an included angle between the first direction X and the second direction Z is an acute angle.
It should be noted that the first direction X shown in fig. 1(B) is a row direction, but the present embodiment does not specifically limit the direction of the first direction X, and may be set according to actual requirements, for example, the first direction X may also be a column direction; the second direction Z is a direction inclined to the right and downward, and the direction of the second direction Z is not specifically limited in this embodiment, and only an acute angle is required to be formed between the first direction X and the second direction Z; in this embodiment, the shapes of the first sub-pixel 11 and the second sub-pixel 21 are not particularly limited, and the shapes of the first sub-pixel 11 and the second sub-pixel 21 may be the same or different.
Compared with the prior art, the shape of the first sub-pixel 11 and the shape of the adjacent second sub-pixel 21 are spliced into the first pattern 3 with the first common edge 30, and the color of the first sub-pixel 11 is the same as the color of the second sub-pixel 21, so that the first sub-pixel 11 and the adjacent second sub-pixel 21 can be integrally formed, that is, the evaporation of one first sub-pixel 11 and one second sub-pixel 21 can be completed through the opening sharing the same mask. By the method, on one hand, the number of the sub-pixels in the display area can be increased, so that the pixel density of the display area is improved, and the high resolution of the display panel is realized; on the other hand, the first sub-pixel 11 and the second sub-pixel 21 share one mask opening, so that the opening density of the mask can be reduced, and the difficulty in preparing the mask for evaporating the pixel structure is reduced.
Compared with the prior art, the embodiment of the invention has two first sub-pixels 11 of each first pixel unit 1, and the two first sub-pixels 11 are oppositely arranged in the first direction X; the number of the second sub-pixels 21 of each second pixel unit 2 is two, and the two second sub-pixels 21 are oppositely disposed in the first direction X. By taking the first sub-pixels 11 and the second sub-pixels 21 as an example, which are sequentially arranged in the row direction shown in fig. 1, through the arrangement of such a structure, the number of the first sub-pixels 11 and the second sub-pixels 21 in each row can be increased, so that the pixel density of the display area is further improved, and further, the higher-resolution display of the display panel is realized.
Specifically, in the prior art, in order to improve the resolution of the display panel, it is necessary to increase the pixel density of the display area, that is, to reduce the spacing between adjacent sub-pixels, so as to increase the number of sub-pixels in the display area with the same size. Because the sub-pixels are formed by evaporation of the mask, only one sub-pixel can be prepared in one opening of the existing mask, the number of the sub-pixels in the display area with the same size can be increased only by increasing the opening ratio of the mask, and the deposition reliability is reduced when the opening ratio of the mask is increased, the preparation difficulty is too high on the other hand, and the mask with the high opening ratio is difficult to prepare by the existing process. According to the embodiment, the two sub-pixels share one mask, so that the opening rate of the mask can be reduced, the preparation difficulty of the mask can be reduced, the number of the sub-pixels in the display area with the same size can be increased, and the resolution of the display panel can be improved.
In this embodiment, the first pixel unit 1 includes a third sub-pixel 12 and a fourth sub-pixel 13 that are oppositely disposed in the third direction Y, the shape of the third sub-pixel 12 and the shape of the fourth sub-pixel 13 are spliced to form a second pattern 4 having a second common edge 40, and the two first sub-pixels 11 are respectively disposed on two sides of the second pattern 4; the second pixel unit 2 includes a fifth sub-pixel 22 and a sixth sub-pixel 23 oppositely disposed in the third direction Y, the shape of the fifth sub-pixel 22 and the shape of the sixth sub-pixel 23 are spliced to form a third pattern 5 having a third common edge 50, and the two second sub-pixels 21 are respectively disposed on two sides of the third pattern 5.
Referring to fig. 2(a), each first pixel unit 1 includes a sub-pixel unit 101 and a sub-pixel unit 102, and the sub-pixel unit 101 is composed of a left first pixel 11, and a middle third sub-pixel 12 and a middle fourth sub-pixel 13; the sub-pixel unit 102 is composed of the first pixel 11 on the right side and the third and fourth sub-pixels 12 and 13 located in the middle, that is, the sub-pixel unit 101 and the sub-pixel unit 102 share the third and fourth sub-pixels 12 and 13. Referring to fig. 2(B), each second pixel unit 2 includes a sub-pixel unit 201 and a sub-pixel unit 202, and the sub-pixel unit 201 is composed of a left second pixel 21 and a middle fifth sub-pixel 22 and a sixth sub-pixel 23; the sub-pixel unit 202 is composed of the second pixel 21 on the right side and the fifth and sixth sub-pixels 22 and 23 located in the middle, that is, the sub-pixel unit 201 and the sub-pixel unit 202 share the fifth and sixth sub-pixels 22 and 23. As can be seen from fig. 2, the first pixel 11 is in contact with the third sub-pixel 12 and the fourth sub-pixel 13, and the second pixel 21 is in contact with the fifth sub-pixel 22 and the sixth sub-pixel 23.
Since in the prior art, one pixel unit is formed by three sub-pixels, that is, six sub-pixels are required for two pixel units, the two pixel units of the present embodiment share two sub-pixels (the sub-pixel unit 101 and the sub-pixel unit 102 share the third sub-pixel 12 and the fourth sub-pixel 13, and the sub-pixel unit 201 and the sub-pixel unit 202 share the fifth sub-pixel 22 and the sixth sub-pixel 23), so that only four sub-pixels are required to form two pixel units, and thus more pixel units can be formed in a display area with the same size, and the resolution of the display panel is further improved.
Referring to fig. 3, the color of the third sub-pixel 12 is the same as that of the fifth sub-pixel 22, and the color of the fourth sub-pixel 13 is the same as that of the sixth sub-pixel 23; the third sub-pixels 12 and the sixth sub-pixels 23, and the fourth sub-pixels 13 and the fifth sub-pixels 22 are all arranged alternately along the first direction X, and the shape of the third sub-pixels 12 and the shape of the fifth sub-pixels 22 adjacent to each other in the third direction Y are spliced into a fourth graph 6 having a fourth common edge 60; the shape of the fourth sub-pixel 13 is stitched to the shape of the sixth sub-pixel 23 adjacent in the third direction Y to form a fifth pattern 7 having a fifth common edge 70. Through the arrangement of the structure, the third sub-pixel 12 and the fifth sub-pixel 22, and the fourth sub-pixel 13 and the sixth sub-pixel 23 can share the same mask opening, so that the number of sub-pixels in the display area with the same size is further increased, and the resolution of the display panel is further improved.
It should be noted that in the present embodiment, the first sub-pixel 11 and the second sub-pixel 21 have the same shape; preferably, the shape of the first sub-pixel 11 includes any one of a triangle, a semicircle, and a trapezoid. As shown in fig. 1, the first sub-pixel 11 and the second sub-pixel 12 are both triangular, and the adjacent first sub-pixel 11 and the second sub-pixel 12 are spliced into a diamond. It can be understood that, because the boundary of the display area has a certain radian, it is easy to cause more square or strip-shaped sub-pixels to fall outside the boundary of the display area in the prior art, and because the sub-pixels outside the display area do not emit light, that is, the light-emitting unit composed of the sub-pixels does not emit light, so that the boundary with the radian has a jaggy feeling during display.
Further, the third sub-pixel 12 and the fourth sub-pixel 13 have the same shape; preferably, the third sub-pixel 12 is the same shape as the fifth sub-pixel 22.
Further, the fifth sub-pixel 22 and the sixth sub-pixel 23 have the same shape; preferably, the shape of the first sub-pixel 11 is an isosceles right triangle, and the shapes of the third sub-pixel 12, the fourth sub-pixel 13, the fifth sub-pixel 22 and the sixth sub-pixel 23 are all pentagons. It can be understood that, by the arrangement of such a structure, the shape of the fourth pattern 6 formed by splicing the third sub-pixel 12 and the adjacent fifth sub-pixel 22 is the same as the shape of the fifth pattern 7 formed by splicing the fourth sub-pixel 13 and the sixth sub-pixel 23, so that the same mask can be used for vapor deposition, and the production cost of the display panel with the pixel structure 100 is reduced.
A second embodiment of the present invention relates to a display panel including: the pixel structure comprises a substrate and the pixel structure arranged on the substrate.
The display panel may be a flexible organic light emitting display panel or a non-flexible organic light emitting display panel. The light emitting mode of the organic light emitting display panel may be top emission, bottom emission, or dual emission.

Specifically, the shape of the first pattern is the shape of the portion where the light emitting layer contacts the anode, and therefore, the shape of the first opening 310 of the first mask 31 for evaporating the light emitting layers of the first sub-pixel and the adjacent second sub-pixel is designed as shown in fig. 4, and the shape of the light emitting layer evaporated by the embodiment of the present invention is the shape of the first pattern shown in any one of fig. 1 to 3.
