OLED display and AMOLED display diode, do they have differences? Tuo Xiaobian to analyze and analyze with everyone, although LED is more common in daily life, but in the screen, each LED is very small in size, and It is divided into three sub-pixel groups of red, green and blue, and then different colors are formed, and the arrangement of sub-pixels also affects the overall display effect. The O in AMOLED stands for Organic, which is "organic". Simply put, a series of organic film materials are used between the positive and negative electrodes to achieve the purpose of illuminating.
AMOLED belongs to OLED, but the reverse is not the case. Simply put, OLED technology includes PMOLED and AMOLED. PMOLED does not require TFT backplane (different from liquid crystal backplane), but the size cannot be made very large; AMOLED size can be made very large. PMOLED is mainly used in early dual-screen mobile phones for small external screens. Currently, mobile TVs use AMOLED technology.
OLED is an organic light-emitting diode, and its luminescent material is an organic luminescent material, which is relative to an LED light-emitting diode. As long as the OLED is charged with the correct voltage at the positive and negative poles, it will illuminate, and the light bulb is the same. When it is signaled, he will work.
AMOLED is an active organic light-emitting diode. It not only needs to add signal, but also needs to supply additional point source to make the diode work. When it gives a bright or no light signal, it will light or shut down. It's not an inappropriate analogy. It works like a TV. You pick up a wired signal, but you can't see it. You only have to pay for it. But only to give electricity, not to cable signals, there is no program to watch.
From a structural point of view, the OLED is basically a diode, and the AMOLED is a three-stage tube or a plurality of transistors to jointly drive one light-emitting point.
