Problems solved by technology
In order to separately control the display function of the camera area, a polymer network liquid crystal (Polymer Network Liquid Crystal, referred to as PNLC) / polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal, referred to as PDLC) liquid crystal cell is usually used in the camera area, so that the liquid crystal cell can control To take pictures and hide the camera device, the liquid crystal box needs to be separated from the liquid crystal box in the main screen display area by frame glue, but the frame glue will cause black borders between the camera display area and the main screen display area, and affect the display effect

Abstract
The invention discloses a display panel and a manufacturing method thereof. The display panel includes a liquid crystal layer. The liquid crystal layer includes a first liquid crystal layer and a second liquid crystal layer. The first liquid crystal layer and the second liquid crystal layer are disposed with spacing through a blocking wall. An area where the first liquid crystal layer is located corresponds to a first display area of the display panel. An area where the second liquid crystal layer is located corresponds to a second display area of the display panel. Width of vertical projection of the blocking wall in a direction of the liquid crystal layer is less than a preset width threshold. According to the display panel, liquid crystal molecules in the first display area and the second display area are isolated through adopting a polymer blocking wall manner instead of an existing frame sealant manner, a light cover exposure manner is adopted for polymerization to form a blockingwall shape, thus it is realized that thickness of the blocking wall is less than 50 microns, and a black edge effect at a junction of the first display area and the second display area is eliminatedvisually.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the continuous development and advancement of low-temperature polycrystalline silicon (LTPS) small-size display technology, full-screen technology has become the mainstream technology in the mobile phone market. The notch full-screen and beauty-point full-screen derived from the goal of full-screen And blind-hole full-screen technology emerges in an endless stream, and its ever-increasing screen-to-body ratio of mobile phones continues to push the full-screen technology to the extreme. [0003] However, the above three technologies all need to dig a hole or deform part of the area, so that the location area of the camera is exposed and used for taking pictures, so it is impossible to achieve a true full-screen display effect. For this reason, people are also trying to further increase the s...
