What is the difference between LCD and OLED? What is the principle of OLED lighting?
In recent years, with the upgrading of color TV technology, LCD technology seems to have reached a peak period of prosperity, a variety of improved technologies emerge one after another. However, the evolution of history tells us that “the prosperity is bound to decline”. It is not that the liquid crystal technology is retrogressive, but that the rapidly evolving technology has spawned a new display technology revolution. It is superior to liquid crystal, and it is the third generation of display technology OLED.
The LCD is called the Liquid-Crystal Display (LCD) and mixes different colors based on white light passing through the color filter. After the white light passes through, basic colors such as red, green, and blue are formed, and the light rate of each pixel is controlled by the current, thereby controlling the color of the pixel.
In the LCD display, it is very difficult to completely cover the white display black, because it will inevitably lead to some light leakage phenomenon, and this is why it cannot appear pure black on most LCD screens. "s reason.
OLED full name Organic Light-Emitting Diode, each pixel itself will emit light without the need for a separate backlight or color filters. Each OLED pixel can be assigned three colors of red, green, and blue, while manufacturers also add yellow, but the principle is the same.
Due to the special properties of OLEDs, it is not necessary to cover the light source like the LCD when displaying black, and only the pixels need to be extinguished to not emit light. This is why OLED displays can bring pure "black". In terms of technology, OLED is definitely better than LCD, simpler structure, more direct and effective light-emitting mode, and thinner and safer product form. OLED becomes the mainstream display technology in the future without any doubt.
