The reference design uses gallium nitride microLED chips from Glo AB (Lund, Sweden). That company has patented a room-temperature wafer transfer technology that allows millions of RGB microLEDs to be transferred and bonded to active backplanes made out of Si, glass or flexible substrate materials.
Part of Glo's business model is to work with licensees and manufacturing partners. This prototype realizes a micro LED display with high brightness and wide viewing angles, applying the LTPS backplane technology developed by JDI.
The display measures 1.6 inches on the diagonal and has 300 by 300 by RGB pixels. The density is 265 pixels per inch. The display has a brightness of 3,000 candelas per square meter.
MicroLEDs are expected to gradually take over from liquid crystal displays, which have been JDI's stock in trade.
The micro LED display no longer requires the backlight, polarizer and color filter required in LCD, where high brightness and wide viewing angles are the characteristics of the next generation displays.
