Description

A TV with good dust-proof effect

technical field

The utility model relates to the technical field of televisions, in particular to a television with good dustproof effect.

Background technique

Television refers to the use of electronic technology and equipment to transmit moving images and audio signals, that is, television receivers, and is also an important broadcast and video communication tool. Television was first invented in 1925 by British engineer John Logie Baird. Televisions use electrical methods to transmit live visual images in real time. Similar to movies, television uses the visual residual effect of the human eye to display frame-by-frame still images, forming visually moving images. The sending end of the TV system converts each tiny part of the scene into electrical signals according to brightness and chromaticity, and then transmits them sequentially. At the receiving end, the brightness and chromaticity of each tiny part are displayed according to the corresponding geometric position to reproduce the entire original image. The advancement of science and technology is an important reason for the rapid popularization of television. The TV signal scanning system and the channel broadband are not exactly the same in various countries, and they are distinguished by Latin letters according to the recommendations of the International Radio Consultative Committee (CCIR). The process of TV signal transmission and distribution, taking live broadcasting in other cities as an example, generally starts from the camera, TV center or OB van, then passes through the microwave relay line, the transmitting station, and finally reaches the user's TV receiver. In addition, television broadcasting satellite and cable television are also effective means of national and city-regional distribution of television transmissions, respectively.
