The difference between LED and OLED panels lies in luminous principle, structure, screen thickness, display effect and service life.
The difference between LED and OLED panels lies in luminous principle, structure, screen thickness, display effect and service life.In the principle of light-emitting, the LED panel displays the picture through the light-emitting diode and the molecular deflection of the liquid crystal layer, while the OLED panel is self luminous (each pixel can emit monochromatic light);In terms of structure, LED panel is a multi-layer structure, while OLED panel has fewer layers, and the structure is relatively simple. OLED is very thin because it does not need backlight, so the OLED screen is about one third of the thickness of the LED screen, or even thinner; OLED panel is also flexible, which is totally impossible for LED panel;Display effect: LED screen can generally achieve 72% of NTSC gamut, while OLED is more prominent, which can reach 100% of NTSC. It can meet the needs of BT 2020 and other gamut with higher requirements, but there may be problems of color temperature and color deviation;Service life: LED screen does not burn, OLED screen is easy to burn after long use, and LED has more advantages in service life.. AMOLED has bright colors and higher brightness. But at present, there are many problems such as color deviation and too bright minimum brightness, which need to be solved by software. And the pixel arrangement of pencil is generally used, so the precision is not enough. The latest super AMOLED plus corrects the problem of pixel arrangement, but it also brings about the hard injury of missing dark details..SLCD and TFT have the same origin. The color and brightness are not as good as AMOLED. The color deviation is not as serious as AMOLED. It's an ordinary screen, better than ordinary TFT...
