OLED

The full name of OLED is organic light emitting diode (OLED). Unlike the LCD mentioned earlier, OLED does not need backlight support. OLED is a kind of congenital surface light source technology. The light can be red, green, blue, white and other monochromatic, so as to achieve the full-color effect. It belongs to a new light-emitting principle. The reason why plasma technology, OLED technology and even early CRT technology are praised for their image quality is that they all have the feature of "self illumination". OLED technology can turn off independent pixels and set their Brightness to zero. In theory, the contrast of OLED technology can be infinite. Therefore, OLED is impossible to leak light in black field, so as to improve contrast and image quality. In addition, OLED technology does not need the support of backlight, so the LCD and backlight module are omitted, the structure is very simple, and the body can be ultra-thin naturally, about 1 / 3 of the thickness of the traditional LED screen. OLED also has flexible and bendable features, which can not only be applied to TV, but also make intelligent devices full of imagination space in the future. Combined with the characteristics of OLED thin, the screen can be made as thin as a piece of paper and can be bent and folded at will, which is unimaginable in the LCD era.

Finally, whether LCD or OLED, as long as it exists, it has its meaning.
