Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present invention. However, the claimed invention may be practiced without these specific details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a pixel structure, specifically configured 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 of 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 along the first direction X, and the shapes of the first sub-pixels 11 and the shapes of the adjacent second sub-pixels 21 are spliced into a first graph 3 with a first common side 30; the first pixel units 1 and the second pixel units 2 are alternately arranged along the second direction Z, and an included angle between the first direction X and the second direction Z is an acute angle.
Note that, the first direction X shown in fig. 1 (B) is a row direction, and the direction of the first direction X is not specifically limited in this embodiment, and may be set according to actual requirements, for example, the first direction X may be a column direction; the second direction Z is a downward-right oblique direction, and the direction of the second direction Z is not specifically limited in this embodiment, and only the acute angle between the first direction X and the second direction Z is required to be ensured; the shapes of the first subpixel 11 and the second subpixel 21 are not particularly limited in this embodiment, and the shapes of the first subpixel 11 and the second subpixel 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 graph 3 with the first common side 30, and the color of the first sub-pixel 11 is the same as that 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, evaporation of one first sub-pixel 11 and one second sub-pixel 21 can be completed through sharing the opening of the same mask plate. By the mode, 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 plate opening, so that the opening density of the mask plate can be reduced, and the preparation difficulty of evaporating the mask plate of the pixel structure is reduced.
In the embodiment of the present invention, compared with the prior art, the number of the first sub-pixels 11 of each first pixel unit 1 is two, 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. Taking the first sub-pixel 11 and the second sub-pixel 21 as an example, which are sequentially arranged in the row direction shown in fig. 1, by the arrangement of this structure, the number of the first sub-pixel 11 and the second sub-pixel 21 in each row can be increased, so that the pixel density of the display area is further improved, and further, higher resolution display of the display panel is realized.
In particular, in the related 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 pitch between adjacent sub-pixels, so as to increase the number of sub-pixels within the same size display area. Because the subpixels are formed through evaporation of the mask plate, one opening of the existing mask plate can only prepare one subpixel, so that the opening ratio of the mask plate needs to be increased to increase the number of subpixels in the display area with the same size, on one hand, the deposition reliability can be reduced, on the other hand, the preparation difficulty is too large, and on the other hand, the existing process is difficult to prepare the mask plate with high opening ratio. According to the embodiment, the two sub-pixels share the same mask plate, so that the preparation difficulty of the mask plate can be reduced while the aperture ratio of the mask plate is reduced, and meanwhile, the number of the sub-pixels in the display area with the same size can be increased, and the resolution of the display panel is improved.
In this embodiment, the first pixel unit 1 includes a third subpixel 12 and a fourth subpixel 13 that are disposed opposite to each other in the third direction Y, the shape of the third subpixel 12 and the shape of the fourth subpixel 13 are spliced into a second pattern 4 having a second common side 40, and two first subpixels 11 are disposed on both sides of the second pattern 4, respectively; the second pixel unit 2 includes a fifth sub-pixel 22 and a sixth sub-pixel 23 disposed opposite to each other in the third direction Y, the shape of the fifth sub-pixel 22 and the shape of the sixth sub-pixel 23 are stitched into a third pattern 5 having a third common side 50, and two second sub-pixels 21 are disposed on both sides of the third pattern 5, respectively.
Referring to fig. 2 (a), each first pixel unit 1 includes a sub-pixel unit 101 and a sub-pixel unit 102, where the sub-pixel unit 101 is composed of a first pixel 11 on the left side, and a third sub-pixel 12 and a fourth sub-pixel 13 in the middle; 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, wherein the sub-pixel unit 201 is composed of a second pixel 21 on the left side, a fifth sub-pixel 22 and a sixth sub-pixel 23 in the middle; the sub-pixel unit 202 is composed of the second pixel 21 on the right side and the fifth and sixth sub-pixels 22, 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, 23. As can be seen from fig. 2, the first pixel 11 is in contact with the third 12 and fourth 13 sub-pixels, and the second pixel 21 is in contact with the fifth 22 and sixth 23 sub-pixels.
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 in this 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 the same display area, and the resolution of the display panel is further improved.
Referring to fig. 3, the third sub-pixel 12 has the same color as the fifth sub-pixel 22, and the fourth sub-pixel 13 has the same color as the sixth sub-pixel 23; the third sub-pixel 12 and the sixth sub-pixel 23, the fourth sub-pixel 13 and the fifth sub-pixel 22 are all alternately arranged along the first direction X, and the shape of the third sub-pixel 12 and the shape of the fifth sub-pixel 22 adjacent to each other in the third direction Y are spliced into a fourth pattern 6 having a fourth common side 60; the shape of the fourth sub-pixel 13 and the shape of the sixth sub-pixel 23 adjacent in the third direction Y are stitched into a fifth pattern 7 having a fifth common side 70. Through the arrangement of the structure, the third sub-pixel 12, the fifth sub-pixel 22, the fourth sub-pixel 13 and the sixth sub-pixel 23 can share the same mask opening, so that the number of the 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 triangle, semicircle, trapezoid. As shown in fig. 1, the first sub-pixel 11 and the second sub-pixel 12 are triangular, and adjacent first sub-pixel 11 and second sub-pixel 12 are spliced into a diamond shape. It can be understood that, since the boundary of the display area has a certain radian, more square or strip-shaped sub-pixels in the prior art are easy to fall outside the boundary of the display area, and since the sub-pixels outside the display area do not emit light, that is, the light emitting unit formed by the sub-pixels does not emit light, the boundary with radian has a jaggy feel during display, and the sub-pixels with a certain angle are more attached to the boundary of the display area by designing the shape (such as triangle) of the sub-pixels in the implementation mode, the number of the sub-pixels falling outside the boundary of the display area is reduced, so that the display effect of the display area is improved.
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 has the same shape as the sixth sub-pixel 23; more preferably, the first sub-pixel 11 has the shape of an isosceles right triangle, and the third sub-pixel 12, the fourth sub-pixel 13, the fifth sub-pixel 22 and the sixth sub-pixel 23 each have the shape of a pentagon. It can be understood that by the arrangement of this structure, the fourth pattern 6 formed by splicing the third sub-pixel 12 and the adjacent fifth sub-pixel 22 is identical to the fifth pattern 7 formed by splicing the fourth sub-pixel 13 and the sixth sub-pixel 23, so that the same mask plate can be used for vapor deposition, and the production cost of the display panel with the pixel structure 100 is reduced.

The display panel may be a flexible organic light emitting display panel or an inflexible organic light emitting display panel. The light emission mode of the organic light emitting display panel may be top emission, bottom emission, or double-sided emission.
The display panel can be further packaged in a display device, and the display device can be applied to intelligent wearable equipment (such as an intelligent bracelet and an intelligent watch) and also can be applied to equipment such as an intelligent mobile phone, a tablet personal computer and a display.

Specifically, the shape of the first pattern is the shape of the portion where the light emitting layer contacts the anode, so in the embodiment of the present invention, the shape of the light emitting region may be determined by the shape of the light emitting layer when the area of the anode is larger than the area of the light emitting layer by designing the shape of the first opening 310 of the first mask plate 31 for vapor deposition of the light emitting layer of the first sub-pixel and the adjacent second sub-pixel to be the shape shown in fig. 4 and the shape of the vapor deposited light emitting layer to be the shape of the first pattern shown in any one of fig. 1 to 3. Of course, the shape of the first pattern shown in any one of fig. 1 to 3 may be formed by designing the shape of the anode, that is, when the area of the light emitting layer is larger than that of the anode, the shape of the light emitting region may be determined by the shape of the anode.
Referring to fig. 5, since the pixel structure includes a third sub-pixel and a fourth sub-pixel that form a first pixel unit together with the first sub-pixel, and a fifth sub-pixel and a sixth sub-pixel that form a second pixel unit together with the second sub-pixel, the mask set 300 further includes:
