Is there a difference between OLED display screens and AMOLED display diodes?
OLED display and AMOLED display diode, are they different? Although LEDs are also more common in daily life, but in the screen, the size of each LED is very small, and it is divided into three sub-pixel groups of red, green and blue, and then form different colors, and the arrangement of subpixels will also affect the entire display effect. The O in AMOLED stands for Organic, that is, "organic", simply put, a series of organic film materials are used in the time between the positive and negative electrodes to achieve the purpose of luminescence.
AMOLED belongs to OLED, but not the other way around. Simply put, OLED technology includes PMOLED and AMOLED, PMOLED does not need TFT backplane (different from the backplane of liquid crystal), but the size cannot be made very large; AMOLED sizes can be made very large. PMOLED mainly exists in early dual-screen mobile phones, used for small external screens, and current mobile TVs use AMOLED technology.
OLED, is the organic light-emitting diode, its light-emitting material is organic light-emitting material, is relative to the LED light-emitting diode. As long as the OLED adds the correct voltage to the positive and negative poles, it will emit light, which is the same as the light bulb, add a signal to it, and he will work.
AMOLED is an active organic light-emitting diode, it not only needs to add a signal to work, but also needs to supply an additional point source, so that the diode reaches the working state, at this time to give a light or not light signal, it will light up or close. To use an inappropriate analogy, it works like a television set, you connect it with a wired signal, but you can't watch it, you can only watch it if you give electricity. But only electricity, not cable signals, there is no program to watch.
From a structural point of view, OLED is basically a diode, and AMOLED is a tertiary or multiple transistors to drive a light-emitting point.
