example 1

[0155] In order to reduce the changes to the manufacturing process when manufacturing the display screen 20 , the structure of the display screen 20 is improved.

[0156] In some embodiments, such as Figure 7 As shown, the display screen 20 further includes a plurality of third light emitting devices 24 located between adjacent second pixels 221 .

[0157] A row of third light-emitting devices 24 located between two adjacent rows of second pixels 22 arranged in an array, and first sub-pixels 211 of a row of first pixels 21 arranged in a plurality of arrays The light emitting devices 213 are arranged in a row.

[0158] A column of third light-emitting devices 24 located between two adjacent columns in the second pixels 22 arranged in an array, and the first sub-pixels 211 in a column of the first pixels 21 arranged in an array The light emitting devices 213 are arranged in the same row.

[0159] That is to say, the arrangement rule of the plurality of third light-emitting d...

example 2

[0171] In order to further increase the transmittance of the blank area, the structure of the second light emitting device 223 in the display screen 20 is improved.

[0172] like Figure 9 As shown, the pixel defining layer 25 includes a plurality of intersecting barrier walls 251 and a plurality of first openings 252 surrounded by the plurality of intersecting barrier walls 251 .

[0173] It can be understood that the pixel defining layer 25 is disposed on the side of the first driving circuit 212 and the second driving circuit 222 away from the substrate 23 .

[0174] Wherein, the plurality of first openings 252 are located in the first sub-pixel 211 and the second sub-pixel 221 .

[0175] example, such as Figure 10a As shown, a first opening 252 is located in a first sub-pixel 211 .

[0176] That is to say, each first sub-pixel 211 in the display screen 20 corresponds to a first opening 252 , and the first opening 252 defines the light transmission range of the correspo...

example 3

[0190] The difference between the third example and the second example is that the structure of the pixel defining layer 25 is different.

[0191] Such as Figure 11a As shown, the pixel defining layer 25 further includes at least one second opening 253 surrounded by a plurality of intersecting retaining walls 251 .

[0192] The second opening 253 is located between adjacent second pixels 22 among the plurality of second pixels 22 arranged in an array, and is used for separating adjacent second pixels 22 .

[0193] That is to say, since the second sub-pixels 221 do not need to be arranged between adjacent second pixels 22, the structure of the first opening 252 does not need to be arranged, but the second openings that at least pass through three second sub-pixels 221 are arranged. 253 structures. In this way, compared to Figure 10b As shown, no retaining wall 251 is set in the blank area between adjacent second pixels 22 . Since the blocking wall 251 is a light-shielding...

Abstract

The invention provides a display screen and a terminal, and relates to the technical field of display. The invention is used for solving the problem of how to improve the transmittance of an OLED display screen. The display screen comprises a substrate, at least one high-density pixel group and at least one low-density pixel group. The high-density pixel group comprises a plurality of first pixelsarranged in an array, and the low-density pixel group comprises a plurality of second pixels arranged in an array. The first pixel comprises at least three first sub-pixels used for displaying threeprimary colors respectively, and each first sub-pixel at least comprises a first driving circuit and a first light-emitting device electrically connected with the first driving circuit. The second pixel comprises at least three second sub-pixels used for displaying three primary colors respectively. Each second sub-pixel at least comprises a second driving circuit and a second light-emitting device electrically connected with the second driving circuit. The pixel density of the first display area where the first pixels arranged in the array mode are located is larger than the pixel density ofthe second display area where the second pixels arranged in the array mode are located.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display screen and a terminal. Background technique [0002] With the development of display technology, terminal equipment with a high screen-to-body ratio has become a product type that is more popular with consumers. Optical devices must occupy a certain area on the display surface of the terminal equipment because they need to collect the light on the side of the terminal equipment display surface. Therefore, they have become the main influencing factors that limit the full-screen display of the terminal equipment. [0003] For terminal equipment including an organic light-emitting diode (OLED) display, since the OLED display is not completely opaque, in order to simplify the structure, a commonly used design is to arrange optical devices on the OLED display. The light-receiving surface of the optical device faces the back of the OLED display. However, since th...
