Abstract

The present application provides an OLED display panel, a preparation method thereof, and an OLED display device. The OLED display panel includes a backplane, a substrate, a driving circuit layer, a light-emitting functional layer, and an encapsulation layer. The substrate is disposed on the backplane, and the The driving circuit layer is arranged on the substrate, the light-emitting functional layer is arranged on the driving circuit layer, and the encapsulation layer is arranged on the light-emitting functional layer, wherein the electronic components at the positions corresponding to the electronic components are arranged The sum of the thicknesses of the backplate and the substrate in the setting area is smaller than the sum of the thicknesses of the backplate and the substrate in other areas; The thickness of at least one layer in the backplane is reduced, so that the light transmittance of the electronic component setting area is increased, and the under-screen camera area can be displayed normally. There is no need to dig a hole to realize the under-screen camera, which increases the screen ratio and solves the problem of existing problems. The OLED display panel has the technical problem that the camera area under the screen needs to be drilled, which affects the display effect.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an OLED display panel, a preparation method thereof, and an OLED display device. Background technique [0002] In order to increase the screen ratio of the existing OLED (Organic Light-Emitting Diode) display panel, the camera is placed under the display panel, but when the camera is placed under the display panel, the display panel will block the camera Therefore, special-shaped cutting of the camera area under the screen is required, resulting in the need to dig holes in the camera area under the screen, and the hole-digging area cannot be displayed, which affects the display effect. [0003] Therefore, the existing OLED display panel has the technical problem that the camera area under the screen needs to be drilled, which affects the display effect. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide an OLED display panel, a met...
