Micro LED Will Become A Potential Micro-display Technology For AR/VR Devices

- Feb 28, 2019-

  According to industry sources, the rapid development of AR/VR applications promotes the demand for micro-display devices. At present, these micro-display devices mainly use LCoS, HTPS and AMOLED, but in the long run, inorganic micro-LED display technology can be comparable to the mainstream technology of current micro-display applications.

    Sources said that micro-displays had been used as electronic viewfinders (EVF) in digital cameras, but since the advent of smartphones with built-in cameras, the market demand for micro-displays has gradually become weak. With the gradual popularization of AR/VR devices, the application of micro-display devices in smart glasses and head-mounted display (HMD) has begun to return to the growth track.

     According to data provided by Fuji Chimera Research Institute, a Japanese Market Research institute, silicon-based liquid crystal (LCoS) accounted for 59.7% of the market share of the three main micro-display technologies in 2018, followed by AMOLED (27.8%) and HTPS (6.6%).

     Meanwhile, in 2018, the global market for microdisplays reached $161 million, including $96 million for LCoS devices, $55 million for AMOLED and $10 million for HTPS.

     AMOLED micro-display market is expected to grow to 750 million US dollars in 2021, with an annual composite growth rate of 10.9% and an average unit price of 32 US dollars, 35% higher than the average unit price of LCoS and HTPS.

     At present, AR glasses equipped with AMOLED panel have been listed, but OLED technology still has great room for improvement in luminous efficiency, production cost and panel usage time. Because Micro LED performs better than OLED in power consumption, brightness, luminous efficiency, response time, panel usage time and temperature adaptability, some manufacturers believe that micro LED can also be used in micro-display technology.

     At this CES 2019, its MicroLED can provide 10 times resolution, 100 times contrast and 1000 times brightness. In addition, the power consumption of the device is cut by half, thus doubling the battery life of portable handheld devices.
