AMOLED is a display technology, the full name is Active Matrix Organic Light Emitting Diode, and the Chinese translation is "active matrix organic light emitting diode". It is a high-end display technology based on organic materials and semiconductor materials, which can provide higher contrast and vivid colors, and also achieve lower power consumption and faster response speed. Therefore, it is widely used in high-end mobile phones, tablets, TVs and other devices.

In AMOLED, each pixel is an LED, which displays images by exciting organic compounds to emit light. An active matrix is made up of an array of transistors, each of which controls the brightness and color of a pixel. In addition, AMOLED also uses self-illuminating technology and does not require a backlight source, so it can achieve higher contrast and color saturation while saving power.

In short, the principle of AMOLED display technology is to integrate organic light emitting diodes into the active matrix to realize the control of the brightness and color of each pixel, so as to achieve high quality, high contrast, high vividness, high speed and low power consumption display Effect.
