Peep-proof liquid crystal display screen

Abstract

The invention discloses a peep-proof liquid crystal display screen which comprises a display screen structure, a protection mechanism, a supporting mechanism and a heat dissipation mechanism. The display screen structure comprises a supporting frame and a rear protection shell, a display screen assembly is embedded in the rear protection shell, a first PE protection film layer is embedded in the center of the front surface of the supporting frame, an AG hardening layer is arranged on the back surface of the first PE protection film layer, a PET layer is arranged on the back surface of the AG hardening layer, and a peep-proof layer is arranged on the back surface of the PET layer. The back side of the peep-proof layer is provided with a blue-light-proof layer, the back side of the blue-light-proof layer is provided with a second PE protective film layer, and the first PE protective film layer, the AG hardening layer, the PET layer, the peep-proof layer, the blue-light-proof layer and the second PE protective film layer are sequentially embedded between the supporting frame and the rear protection shell. During use, height and angle adjustment is more convenient, heat dissipation performance is good, and content displayed on the screen can be protected through the two sides and the front surface and prevented from being peeped.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a peep-proof liquid crystal display. Background technique [0002] Display is an important interface for communication between human and machine. LCM liquid crystal display (LCD) has the advantages of clear and delicate images, no flicker, no eye damage, no radiation, low power consumption, and thinner and lighter. Widely used in various display fields. [0003] However, the existing displays also have the following defects in use: [0004] 1. The adjustment method of the support feet of the display is single, which cannot meet the needs of most users, and cannot be adjusted at multiple angles and heights according to the needs of users; [0005] 2. The thickness of existing displays is getting thinner and thinner. In order to have good heat dissipation performance, the heat dissipation holes are generally opened upwards, and the principle of rising hot air is used to make the...

AI Technical Summary

Problems solved by technology

[0004] 1. The adjustment method of the support feet of the display is single, which cannot meet the needs of most users, and cannot be adjusted at multiple angles and heights according to the needs of users;

[0005] 2. The thickness of existing displays is getting thinner and thinner. In order to have good heat dissipation performance, the heat dissipation holes are generally opened upwards, and the principle of rising hot air is used to make the heat discharge faster. However, this will easily lead to dust accumulation in the heat dissipation holes for a long time. Significantly lower, long-term use is easy to damage the display;

[0006] 3. When the display is in use, users generally do not want people around to observe their own desktop content, and some people are easy to look twice because of their curiosity when passing by, which makes our desktop content easy to be destroyed. to voyeurism, resulting in the leakage of privacy
