Display panel, manufacturing method thereof and display device

Abstract

The embodiment of the invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a first display area and a second display area, wherein the light transmittance of the second display area is smaller than that of the first display area; the first display area comprises a substrate, a driving array layer, a planarization layer and a pixel limiting layer, the driving array layer, the planarization layer and the pixel limiting layer are stacked on the substrate, and the substrate is provided with a first light-transmitting opening; the first light-transmitting opening at least penetrates through one side, far away from the driving array layer, of the substrate, the first light-transmitting opening is filled with a transparent material, and the light transmittance of the transparent material is greater than that of the substrate; a plurality of pixel openings for accommodating light-emitting materials are formed in the pixel limiting layer; a second light-transmitting opening is formed between every two adjacent pixel openings; and the projection of the second light-transmitting opening on the substrate is partially or completely overlapped with the projection of the first light-transmitting opening on the substrate. According to the technical scheme provided by the embodiment of the invention, full-screen display can be realized, the light transmittance of the camera area under the screen is ensured, and the display panel is prevented from generating cracks.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the advent of the era of ubiquitous screens, compared with ordinary displays, full-screen displays have a larger screen-to-body ratio and ultra-narrow bezels, which can greatly improve the visual enjoyment of viewers, thus attracting widespread attention. [0003] In order to achieve a full screen, a display device (such as a mobile phone) is usually provided with a front camera and the like in the display area. In order to ensure that the camera can receive more light, it is necessary to have high requirements on the light transmittance of the display panel. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a display panel, a method for fabricating the same, and a display device. By arranging second light-transmitting openings be...

Problems solved by technology

[0004] Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device. A second light-transmitting opening is provided between pixel openings in a first display area opposite to a photosensitive device, and a substrate with a low light transmittance Set the first light-transmitting opening on the top, and fill the first light-transmitting opening with a transparent material with a high light transmittance to realize a full-screen display, improve the light transmittance of the display panel, and ensure that the photosensitive devices such as the camera under the screen can receive At the same time, if the first light-transmitting opening is not filled, due to long-term gravity, or when the side of the display panel away from the base is attached to the cover, due to excessive pressure, the The side of the driving array layer close to the first light-transmitting opening bends downward and generates cracks, and the cracks extend through the driving array layer to the planarization layer, etc., thereby causing the intrusion of water and oxygen from the outside, leading to the problem that the luminescent material is oxidized and fails
