Under-screen camera display panel and preparation method thereof

Abstract

The invention provides an under-screen camera display panel and a preparation method thereof. The under-screen camera display panel comprises a display panel body and a touch panel arranged on the display panel body; the display panel body comprises at least one transparent area used for receiving external light, and the touch panel comprises an induction electrode and a driving electrode which are arranged in an insulated mode, wherein the induction electrode and / or the driving electrode comprise / comprises a lenticular touch point array prepared from a transparent material; the touch point array is aligned to the sub-pixels of the display panel; the transparent material is a silver nanowire transparent conductor with transparency being greater than 91%, and replaces a traditional aluminum-titanium alloy conductive material; after patterning, film layers with different refractive indexes are matched to serve as a light adjusting layer, so that the light-emitting effect of an under-screen display area is improved, the contrast difference between the under-screen display area and a normal display area is reduced, and the user experience is improved; and the lenticular structure enables emergent light of the display panel to be refracted towards the two sides, so that the view angle of the emergent light is enlarged, and the display quality of the display panel is improved.

Description

Technical field [0001] This application relates to the field of display technology, and in particular to an under-screen camera display panel and a preparation method thereof. Background technique [0002] With the development of the mobile phone industry, under-screen cameras have gradually become a development trend. Under-screen cameras have brought better visual enjoyment and interference-free all-round display. [0003] At present, the under-screen camera of the display panel refers to a type of display that can display the position of the camera. It mainly uses the OLED screen to self-illuminate and can be made into a transparent characteristic. Imaging is realized through the gap between the pixels of the AMOLED screen. In the front camera area, the display panel is a small transparent screen. When not taking pictures, it can display the screen content normally; when taking pictures, it becomes a transparent film. The current mainstream technology is to reduce the loss caus...

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, the full screen in the prior art includes a normal display area 101 and an under-screen display area 102. The density of pixel units 1011 in the normal display area 101 is greater than the density of pixel units 1021 in the under-screen display area 102. Because the pixels in the under-screen display area 102 The number of units 1021 is reduced, resulting in a difference in the light output effect of the display area 102 under the screen and the normal display area 101, which reduces the user experience

[0004] To sum up, it is necessary to design an under-screen camera display panel and its preparation method to solve the technical problem that the light output effect of the under-screen display area is different from that of the normal display area in the prior art, which reduces the user's experience.
