What is AMOLED and LCD What is the difference between AMOLED and LCD

AMOLED stands for Active Matrix Organic Light Emitting Diode, and its core is still LED. Although LEDs are relatively common in daily life, in the screen, the size of each LED is very small and is divided into three sub-pixels of red, green and blue, and then different colors are combined to form different colors, and the arrangement of the sub-pixels It will directly affect the entire display effect.

What is LCD?

The full name of LCD is Liquid Crystal Display, and the way it emits light is very different from that of AMOLED screens. Unlike AMOLED screen pixels that can emit light independently, all pixels of an LCD screen need to rely on a unified backlight layer to emit light. Of course, the large-size LCD screens used on some TVs may also be equipped with multiple light sources to reduce power consumption.

The difference between AMOLED screen and LCD screen

First, the light-emitting principle of an AMOLED screen is different from that of an LCD. The LCD screen emits light from a light-emitting template, which is composed of lamp beads. Theoretically, the more lamp beads, the higher the brightness. AMOLED's pixels are self-luminous, which means they are not as bright as LCD.

Second, because AMOLED pixels are self-luminous, they do not emit light at all when displaying black, which can save power to a certain extent. And due to the self-luminous nature of pixels, AMOLED screens will not have light leakage. The reason why light leakage occurs is because the backlight template of the LCD screen was not packaged properly.

The third issue is the thickness. Since AMOLED screens are not encumbered by backlight templates, their thickness is lower than LCD screens. This means that mobile phones can be thinner and can change the shape of the screen. For example, Samsung's curved screen is actually AMOLED. Screen. The screen can be made into a flexible screen without a backlight module.
