Liquid crystal display, English is commonly known as LCD (Liquid Crystal Display). The LCD liquid crystal television mainly adopts a TFT type liquid crystal display panel, and its main components include a fluorescent tube, a light guide plate, a polarizing plate, a filter plate, a glass substrate, an alignment film, a liquid crystal material, a thin mode transistor, and the like. First of all, the liquid crystal display must first use a backlight, that is, a fluorescent tube to project a light source. These light sources pass through a polarizing plate and then pass through the liquid crystal. At this time, the arrangement of the liquid crystal molecules changes the angle of light passing through the liquid crystal. These rays must then pass through the front colored filter and another polarizer. Therefore, as long as the voltage value of the stimulating liquid crystal is changed, the intensity and color of the last light can be controlled, and in turn, a combination of colors having different shades can be changed on the liquid crystal panel.

According to the New York Times, plasma TV was a symbol of advanced technology for consumers a few years ago, but it has some drawbacks, including image quality, service life, power consumption, etc. For plasma TV manufacturers (including LG Electronics, Panasonic, Philips, Samsung, Sony) are issues to be overcome. As these operators continue to invest heavily in related technologies and manufacturing in this field, they have also made some efforts to change the impression of the consumer, so as to prevent the sales of plasma TVs from sluggish.
