Color mixing distance RGB three colors mixed into a single color distance: pixel pitch (mm) × 500 / 1000
The minimum viewing distance shows the distance of the smooth image: pixel pitch (mm) × 1000/1000
The most suitable viewing distance The viewer can see the distance of the highly clear picture: pixel spacing (mm) × 3000/1000
The farthest viewing distance: screen height (m) × 30
LCD (short for Liquid Crystal Display) liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. The lower substrate glass is equipped with TFT (Thin Film Transistor), and the upper substrate glass is equipped with a color filter. The liquid crystal molecules are controlled by the signal and voltage changes on the TFT. Rotate the direction, so as to control whether the polarized light of each pixel point is emitted or not to achieve the purpose of display. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
According to data from CINNO Research, 2020 is expected to be the first year for mass production of mobile phones with fingerprint recognition under LCD screens.
LCD features:
(1) Low-voltage micro power consumption
(2) The appearance is small and exquisite, the thickness is only 6.5~8mm
(3) Passive display type (no glare, no irritation to human eyes, and no eye fatigue)
(4) The amount of display information is large (because the pixels can be made small)
(5) Easy to colorize (reproduce very accurately on the chromatogram)
(6) No electromagnetic radiation (safe for the human body, conducive to information confidentiality)
(7) Long life (this kind of device has almost no deterioration problem, so the life is extremely long, but the life of the LCD backlight is limited, but the backlight part can be replaced)
