Japan Display (JD) declared this week that it had completed the development of its first Micro-LED module. The model of the Micro LED module, which is a possible building block for next-gen displays and TVs, provides a 265 PPI pixel density. JD will likely be displaying the module at Fintech Japan-2019 later this week.
JDI’s Micro LED display prototype is a square module with a 1.6-inch diagonal and provides a resolution of 300×300 pixels together with a maximum brightness of 3,000 nits. The prototype makes use of gallium nitride LED chips developed by a Micro-LED Pioneer Glo and JDI’s LTPS backplane.
As a part of the event process for Micro-LED displays, the hope is that display manufacturers can assemble full-sized displays by building them out of individual modules such as JDs. A modular approach not only provides more control over yields; however, it could also allow display-makers to easily support multiple resolutions and aspect ratios by altering the number of modules. That mentioned, being able to produce commercial panels in volume is still years off, and for now, JD has made vital progress just in completing their prototype module.
Micro LED technology is a promising candidate for higher-end displays and television that can be available in three to four years. The technology has all the quality benefits that OLED has to offer (over LCD), high contrast, along with individually-controlled LEDs, fast response times, and wide viewing angles. However, equally essential, it doesn’t include the significant disadvantages that OLEDs are recognized for, such as off-axis color shifting and aging-related burn-in.
