Embodiment Construction

[0036] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0037] The present invention is aimed at the display panel and the display device in the prior art, because in order to meet the lighting requirements of the camera under the screen, the display effect in the light-transmitting area is not good, and this embodiment can solve this defect.

[0038] see figure 1 , the display panel provided by the embodiment of the prese...

Abstract

The invention provides a display panel and a display device, the display panel is provided with a main display area and at least one display light-transmitting area, the main display area defines a plurality of first pixel openings, and a first light-emitting layer is arranged on the first pixel openings; a plurality of second pixel openings are defined in the display light-transmitting area, andsecond light-emitting layers are arranged on the second pixel openings; the size of each first pixel opening is larger than that of one second pixel opening, the ratio of the orthographic projection area of the first light-emitting layer on the substrate to the orthographic projection area of the second light-emitting layer on the substrate ranges from 95% to 105%, and only the size of the secondpixel opening of the display light-transmitting area is reduced, but PPI of the display light-transmitting area is not reduced. The display effect of the display light-transmitting area is favorably improved; the design of the mask plate adopted by the display light-transmitting area is kept consistent with the design of the mask plate adopted by the main display area, a mask plate stretching netdoes not need to be modified, a mask plate does not need to be specially designed for the display light-transmitting area additionally, the manufacturing procedure is saved, the process cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Due to the extremely high screen-to-body ratio, the full screen brings people a new visual experience and sensory impact, and has become the goal pursued by display panel manufacturers. [0003] Due to the extremely high screen-to-body ratio, the full screen brings people a new visual experience and sensory impact. Currently, the commonly used design of the under-screen camera is to dig holes in the camera area of ​​the display panel, and the light-transmitting area of ​​the camera does not display the picture. The panel penetration rate will be relatively high, but the user's display experience is not good, and the full-screen effect cannot be presented; another way is to set the display light transmission area on the display panel, and set the screen at the position corresponding to the display light t...
