According to foreign media reports, Diditimes recently released a report that microLED will replace liquid crystal on silicon (LCoS) technology in the future and become the mainstream display technology for AR glasses. Since the launch of Google Glass in 2013, most AR glasses have used a technology called liquid crystal on silicon (LCoS) for displays. But according to Diditimes and its research department, microLEDs are more suitable for use on AR devices.
At present, display technologies including LCoS, laser projection, and AMOLED are considered to be suitable for the production of AR glasses, but these technologies are more or less defective, and microLED technology has obvious advantages. Laser projection can cause damage to the wearer's retina because the laser beam is projected directly onto the retina through the mirror. The self-luminous function of AMOLED is harmless to the human body, but compared with AMOLED, the microLED screen has higher contrast and longer service life. So far, microLED displays have not been mass produced. Although Samsung introduced the microLED prototype at CES, it is difficult to produce these displays. Apple has been working on the development of microLED displays after purchasing LuxVue technology. It is reported that Apple currently has 300 engineers involved in the project.
Digitimes said it hopes Apple's microLED technology products will be available next year, giving other technology companies the power to develop their own microLED devices.
