Outdoor large-screen liquid crystal display screen

Abstract

The invention discloses an outdoor large-screen liquid crystal display screen, and relates to the field of liquid crystal display screens. The outdoor large-screen liquid crystal display screen comprises a frame, a screen body is mounted in the frame, and a solar panel is mounted at the top end of the frame. A baffle is arranged on the outer side of the frame and located on one side of the screenbody, a motor bin is arranged on one side of the baffle, and a motor is mounted in the motor bin. The display screen is provided with the baffle, the motor bin, a gear, a moving plate, teeth, a rain and snow sensor, a controller, a sliding block and an electric push rod. The electric push rod can drive the baffle to slide up and down on one side of the screen body through the sliding block and a sliding groove, the screen body can be shielded when it rains or snows, and the moving plate can move to shield the top end of the screen body, so that the shielding effect is better, the probability that rain and snow enter the screen body is reduced, traces left by rain and snow on the screen body can be reduced, and the screen body is clearer.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a large-screen liquid crystal display screen for outdoor use. Background technique [0002] The outdoor display adopts super grayscale control technology, modular structure design and VLSI design technology, which greatly improves the stability, reliability and playback effect of the display system. [0003] The existing large-screen LCD screens for outdoor use have poor rainproof ability, and the screen is directly exposed to the outside in rainy and snowy weather. The internal heat dissipation effect of the outdoor large screen is not good, and the temperature of the screen cannot be quickly dissipated by simply using air cooling. Contents of the invention [0004] The purpose of the present invention is: in order to solve the poor rainproof ability of the existing large-screen liquid crystal display screen for outdoor use, the screen is also directly exposed to...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the poor rainproof ability of the existing outdoor large-screen liquid crystal display screen, the screen is also directly exposed in rainy and snowy weather, and there is no protective structure to block it, resulting in easy water ingress inside the screen and easy on the screen. Leaving traces of rainwater, and the existing outdoor large-screen internal heat dissipation effect is not good, the problem that the screen temperature cannot be quickly dissipated by simply using air cooling, to provide an outdoor large-screen LCD
