Abstract

The invention discloses a display device and a preparation method thereof. The display device comprises a display area and a non-display area, wherein the display area comprises a light-emitting areaand a non-light-emitting area; the display device comprises a bottom plate, a display panel and an image acquisition device; the display panel comprises a base layer, a thin film transistor and an insulating layer, and a groove in the bottom plate, a thickness reduction area on the base layer and light-transmitting holes in the insulating layer are oppositely arranged. The display device has the technical effects that the light-emitting device is directly integrated into the driving thin film transistor, the aperture opening ratio of the display panel is increased, and the light transmittanceis further enhanced by forming the light-transmitting holes in the non-light-emitting area.

Description

technical field [0001] The invention relates to the display field, in particular to a display device and a preparation method thereof. Background technique [0002] The current development trend of the mobile phone market is to prepare a true full screen. In order to meet the needs of the full screen of mobile phones, panel developers have devoted more energy to the development of OLED displays. The reason is that OLED displays can use flexible substrates. As a base, to achieve the flexibility of the panel, to bend the non-display area to the sides or the back of the panel, so as to increase the screen ratio of the display area as much as possible is the current mainstream design method to realize the full screen of the mobile phone. [0003] Since the birth of the full screen, the screen-to-body ratio and the front camera have been a pair of contradictions. Whether it is placed on the chin like the Xiaomi MX series, or the notch screen of the iPhone-X series, or the small ...
