Split type liquid crystal television

Abstract

The invention relates to the technical field of liquid crystal televisions, specifically to a split type liquid crystal television. The liquid crystal television includes a display part, a signal processing part and a sound system, and also includes a remote control switching circuit, a lightning protection circuit, a Bluetooth control circuit and a video enhancing circuit. The Bluetooth control circuit is used for a mobile phone to be connected with a television, thereby realizing control of the television by the mobile phone, the video enhancing circuit can increase a high-frequency component of a video signal, thereby enhancing the contrast ratio of a television image, and the video enhancing circuit can also be connected between the output end of a VCR and the SCART input end of the television, and the lightning protection circuit applies a single-phase parallel anti-thunderstrike surge circuit of a piezoresistor and a ceramic gas discharge tube to a power supply of the television and mainly includes a lightning protection circuit and a switching power circuit part, the circuit is simple, a composite symmetrical circuit is adopted, common mode and differential mode full protection does not cause a fire phenomenon, thereby better guaranteeing the safety of the television, and the split type liquid crystal television is simple in structure, convenient to operate and high in safety performance, and has very high creativity.

Description

technical field [0001] The invention relates to the technical field of liquid crystal motors, in particular to a split-type liquid crystal television. Background technique [0002] Liquid crystal display is a substance between solid and liquid. It is an organic compound with regular molecular arrangement. If it is heated, it will appear in a transparent liquid state. When it is cooled, it will appear in a turbid solid state of crystalline particles. . It is because of its characteristics that it is called liquid crystal. The molecular structure of liquid crystals used in liquid crystal displays is arranged similar to thin matchsticks, which are called Nematic liquid crystals, and liquid crystal displays made of such liquid crystals are also called LCDs. The LCD TV adds voltage to the liquid crystal between the two glasses, and reproduces the picture through molecular arrangement changes and twists and turns. The screen creates a picture through the collision of electron gr...

AI Technical Summary

Problems solved by technology

In the 1980s, STN-LCD (super twisted nematic) liquid crystal display appeared, and TFT-LCD (thin film transistor) liquid crystal display technology was developed at the same time, but liquid crystal technology is still immature and difficult to popularize

However, its overall security is not high enough, and there is a lack of technical solutions for how to provide a split-type LCD TV with simple structure, convenient operation and high safety performance.
