Liquid crystal television system capable of being used under outdoor environment

Abstract

The invention discloses a liquid crystal television system capable of being used under an outdoor environment, belonging to the technical field of radiated televisions and media and comprising a liquid crystal television panel, a liquid crystal television driving plate, an LED backlight system, an automatic brightness regulating system, an automatic temperature control system, an anti-ultraviolet photic film, a sound reinforcement system and a sealing shell, wherein the liquid crystal television driving plate is connected with the automatic brightness regulating system by an RS 232 interface for controlling the brightness of the liquid crystal television; an audio interface on the liquid crystal television driving plate is connected with the sound reinforcement system; the automatic temperature control system is used for transmitting temperature data to the liquid crystal television driving plate for controlling the work of a blower; and the anti-ultraviolet photic film is bonded to high photic glass in the front of the sealing shell and forms a closed temperature preserving space of an ultra bright television together with the sealing shell. The liquid crystal television system is widely applied to places such as walking streets, bus advertising kiosks, leisure squares, street signposts, ships, cars and the like.

Description

technical field [0001] The technology belongs to the technical fields of radio and television and media, and in particular provides an LCD TV system that can be used in outdoor environments, and is widely used in pedestrian streets, bus advertising kiosks, leisure plazas, street signboards, ships, vehicles and other places. Background technique [0002] Conventional LCD TVs are not suitable for outdoor use due to low backlight brightness, low operating temperature, low anti-interference ability, low anti-ultraviolet ability, low structural strength, and no windproof and rainproof design. Outdoor video displays are all LED Display screens and pictures mainly rely on light boxes for display. The pixel pitch of LED is relatively large, so it is difficult to realize close viewing and clear text display at close range. It is not suitable for small-sized display screens outdoors; A picture is a big waste of advertising resources, and the market needs a display screen for close vi...

AI Technical Summary

Problems solved by technology

The illuminance under outdoor sunlight can reach tens of thousands of cd / m 2 , and the brightness at night can even be as low as 0.1cd / m 2 , there is a huge illuminance gap, setting a single high brightness will not only cause a huge power consumption, but watching an ultra-bright LCD TV under low illuminance will also have a dazzling feeling, so an outdoor unattended LCD TV needs to be Set the automatic brightness adjustment device
