Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel is divided into a display area and a camera shooting area. The camera shooting area comprises a first through hole, a first light-transmitting layer, an inorganic film layer, a second through hole, a second light-transmitting layer and an image acquisition device. The preparation method ofthe display panel comprises a hard substrate providing step, a flexible substrate preparing step, a first etching step, a first light-transmitting layer preparing step, a thin film transistor first preparing step, a second etching step, a second light-transmitting layer preparing step, a thin film transistor second preparing step, a hard substrate stripping step and an image acquisition device setting step. The technical effect of the invention is that the light transmittance of the camera shooting area of the display panel is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, the development of display technology is changing with each passing day, and the emergence of various screen technologies provides infinite possibilities for electronic terminals. Especially with the rapid application of display technology represented by OLED (Organic Light Emitting Diode), various mobile terminals with selling points such as "full screen", "special-shaped screen", "under-screen sound" and "under-screen fingerprint" have begun to rapidly develop. promote. At this stage, major mobile phone and panel manufacturers have launched many products with "full screen" as their selling point, but most of them still adopt the design of "notch screen" and "water drop screen" which is similar to full screen. Existence, a last resort choice to reserve a certain area for it. ...
