TFT LCD screen is one of the best LCD color display devices at present. TFT LCD screen has faster response speed, higher contrast, wider viewing angle, and thinner. So what are the advantages of TFT LCD screen and LCD? The editor will give you a brief introduction.
TFT has good brightness, high contrast, strong layering, and bright colors. The disadvantage is that it consumes more power and costs more. The main components of TFT-type liquid crystal displays include: fluorescent tubes, light guide plates, polarizing plates, filter plates, glass substrates, alignment films, liquid crystal materials, thin-mode transistors, and so on.
LCD, also known as liquid crystal display, is a display that uses liquid crystal control light transmittance technology to achieve color. From the perspective of the structure of the liquid crystal display, the LCD is composed of two parallel glass plates with a thickness of about 1 mm. The liquid crystal material is separated by a uniform interval of 5 μm. Because the liquid crystal material itself does not emit light, there will be two panels on both sides of the display. There is a lamp tube as the light source, and there is generally a backlight board on the back of the LCD screen, whose function is mainly to provide a uniform background light source.
Since the liquid crystal display has the characteristics of a specific direction when outputting the light source, if people stand at a very oblique angle and watch a completely white picture, they are likely to see black or color distortion. And because everyone's vision range is different, if you don't stand within the best angle, you may see errors in the colors.
Although color distortion may occur when viewing LCD displays under certain circumstances, this does not mean that LCDs have no advantages at all. The existence is reasonable, and LCDs still have many advantages. For example, consumers are most concerned about power consumption. The power consumption of LCD is relatively small, and generally LCD displays will use digital interfaces, which are very convenient to use.
