Soft-EPi launches improvement red InGaN epi wafer[May, 2022]
Soft-EPi, a gallium nitride developer, announced on the 2nd that it will develop and release the red gallium nitride epiwafer for the first time in Korea, which is required to improve the performance of micro light emitting diodes (LEDs).
Micro LED refers to an ultra-small LED with a size of 5 to 100 μm. Although the technical difficulty is high, there is no need for a backlight because it emits light by itself. It is considered as a next-generation display because of its excellent brightness, contrast ratio, color reproduction, durability, and power efficiency.
Display technology using micro LED is considered to be the core technology for implementing the metaverse. It is necessary for next-generation displays such as augmented reality (AR), virtual reality (VR), and smart watches. The micro LED implements a red LED using an aluminum gallium indium phosphide (AlGaInP) material. However, there are several difficulties due to the limitations of the physical properties themselves.
