The Chinese full name is active matrix organic light emitting diode or active matrix organic light emitting diode, which is called the next generation display technology. MOLED screen has three layers, namely AMOLED screen, touch screen panel and external protective glass.
AMOLED display screen is composed of numerous large light-emitting diodes, which is superior to the traditional LCD display screen in terms of thickness, viewing angle, energy consumption and color reproduction ability, but the known disadvantages are short service life and difficulty in manufacturing.

The origin of technology
Originated from the organic light-emitting diode display technology, that is, organic light-emitting diode, which has the characteristics of self-luminescence, uses very thin organic material coating and glass substrate, and when current passes through, these organic materials will emit light.
20 10 AMOLED, the world's first integrated touch screen, comes out and is applied to high-end smart models.
principle of operation
AMOLED is based on organic light emitters. Thousands of light sources that can only emit one of three colors, red, green and blue, are placed on the substrate of the screen in a specific form. When a voltage is applied, these light emitters will emit red, green or blue. Voltage conversion also depends on TFT, and various colors can be emitted only after adjusting the proportion of three primary colors.
