Japan Display has announced the development of a prototype micro-LED display. Micro-LED technology is considered the most likely candidate for use in next-generation displays. The manufacturer will show a prototype at the FinTech JAPAN 2019 exhibition, which will be held in Japan from December 4 to 6.
The advantages of the micro-LED display include high brightness and wide viewing angles. Such a display does not require a backlight, a polarizer and a color filter – the required components of liquid crystal displays. The prototype uses a backplane manufactured by Japan Display using LTPS technology and microminiature LEDs created by Glo specialists. This company, created in the USA in 2010, has developed micro-LED display technology on LTPS and Si boards. She holds hundreds of patents for two key areas of technology: gallium nitride (GaN) -based RGB microminiature LEDs, including the world’s only red GaN-based microminiature LED, and fast direct transfer technology of LEDs from a wafer.
The 1.6-inch diagonal prototype has a resolution of 300 x 300 pixels RGB. These settings correspond to a density of 265 dpi. The maximum brightness of the display is 3000 cd / m2, and the viewing angle exceeds 178 °.
