Abstract

The invention provides a display device which comprises a display panel and a supporting layer, the display panel is provided with a light-transmitting area and a binding area, the supporting layer comprises a first supporting layer and a second supporting layer, the first supporting layer is provided with a first part corresponding to the light-transmitting area, and the second supporting layer is provided with a second part corresponding to the binding area. The optical phase delay coefficient of the first part is set to be smaller than the optical phase delay coefficient of the second part, so that the phase delay effect of the supporting layer on the light penetrating through the light-transmitting area is relieved or eliminated, light and shade stripes of the light in the light-transmitting area are prevented, the lighting effect of the under-screen optical element is improved, and the display effect is improved. And compared with the design of digging holes in the supporting layer of the light-transmitting area, the anti-pressure capability of the display panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device. Background technique [0002] With the change of people's aesthetic level and the development of mobile terminal products, full screen is an inevitable trend in the development of terminal products. Based on flexible OLED panels, the binding area can be bent to the bottom of the screen using Pad bending technology, realizing the narrowing of the lower frame; using off-screen optical or ultrasonic fingerprint technology, on-screen sound technology and off-screen camera technology, the sensor can be placed in At the bottom of the screen, the screen ratio is further increased. [0003] There are two kinds of solutions to realize the under-screen camera: blind hole and through-hole. Compared with through-hole screen, blind-hole screen can hide the camera under the screen and display it normally, which is beneficial to increase the screen ratio, so i...
