CRT display: Also known as cathode ray tube display, it shows images by bombarding the phosphor layer on the screen with an electron beam. Its advantages are high color reproduction and good contrast, but its disadvantages are large space occupation, heavy weight and high power consumption. It has been basically phased out at present.
LCD display: Also known as liquid crystal display, it shows images by controlling the state of the liquid crystal to change the transmittance of light. It has the advantages of being thin, lightweight and energy-saving, and is currently the mainstream type of display on the market.
LED display: It adopts LED backlight technology and uses a more efficient light source to illuminate the LCD panel. Depending on the type of LED chip, they can be classified into ordinary LED displays and Mini LED displays, the latter of which can offer higher brightness and contrast.
OLED display: Each pixel emits light independently, eliminating the need for additional backlighting. It has the advantages of high contrast, high color saturation and wider viewing Angle, but it is relatively expensive and has the problems of easy aging and burn-in.
