Abstract

The invention provides a peep-proof display screen structure and a preparation method thereof, relates to the technical field of display, and solves the problem that the brightness and touch sensitivity of a screen are affected by the existing peep-proof technology, the peep-proof display screen structure comprises a liquid crystal box, a black matrix film layer used for reducing light leakage is arranged in the liquid crystal box, and grating structures arranged in a matrix mode are arranged in the liquid crystal box; the grating structure comprises a plurality of blocking parts which are sequentially arranged in the first direction of the liquid crystal box, the blocking parts extend in the second direction perpendicular to the first direction, the blocking parts and light blocking strips, extending in the second direction, of the black matrix film layer are arranged in an overlapped mode, and the grating structure further comprises light transmitting parts located between every two adjacent blocking parts. Light in the large visual angle direction of a product can be blocked, the visual range of a product screen is reduced, and meanwhile the brightness and touch performance of the product screen are not affected.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a privacy-preventing display screen structure and a preparation method thereof. Background technique [0002] When personal handheld devices such as mobile phones are used in public, it is inevitable that they will be peeked at. With the widespread popularity of large-screen smartphones and portable computers, it is even more difficult to ensure that personal privacy information is not peeped. [0003] In order to avoid peeping, there are also mobile phones with a single-layer privacy film that converges light on the market. The basic principle is to set a privacy film on the screen of the mobile phone. The light emitted by the display screen converges, so that the image on the mobile phone screen can be clearly seen only when facing the mobile phone screen. [0004] The privacy technology currently used on the market is mainly PET-based mobile phone privacy film and...
