1. The function of LED chip:

LED chip is the main raw material of LED, and LED mainly relies on the chip to emit light.

2. The composition of LED chip

Mainly composed of several elements such as arsenic (AS), aluminum (AL), gallium (Ga), indium (IN), phosphorus (P), nitrogen (N), and strontium (Si).

3. Classification of LED chips

According to luminous brightness:
A. General brightness: R, H, G, Y, E, etc.
B. High brightness: VG, VY, SR, etc.
C. Ultra-high brightness: UG, UY, UR, UYS, URF, UE, etc.
D. Invisible light (infrared): R, SIR, VIR, HIR
E. Infrared receiving tube: PT
F. Photoelectric tube: PD

According to the composition elements:
A. Binary chips (phosphorus, gallium): H, G, etc.
B. Ternary chips (phosphorus, gallium, arsenic): SR, HR, UR, etc.
C. Quaternary chips (phosphorus, aluminum, gallium, indium): SRF, HRF, URF, VY, HY, UY, UYS, UE, HE, UG

The difference between Mini LED displays and OLED displays

Looking at the development of displays, it has been evolving towards large size, high resolution, and high color gamut. Five years ago, the market was dominated by displays with W-LED backlights and colors that generally covered less than 80% of the Adobe RGB color gamut. It was not until 2022 that Mini LED and OLED
