Plessey to Make Micro LED Displays w/Passive Matrix
March 08, 2020
​
Plessey has added passive matrix microLED displays to its Data-Vµ product family. Following the launch of Plessey’s Data-Vµ segmented microLED display products in 2019, the company has now extended the range with the introduction of passive matrix pixelized microLED displays, based on Plessey’s proprietary monolithic GaN-on-Silicon technology. These micro-displays provide the high brightness/low power image source demanded by the advanced compact optical projectors embedded in AR/MR information systems.  The displays can be customized to provide the specific resolution and color that customers require to present their dynamic content specific to their applications. These applications can take advantage of the high brightness and contrast inherent in Plessey’s microLED technology to produce stunning visual images that can be viewed under a wide range of environmental conditions and at low power consumption. Plessey has demonstrated its first monochrome passive matrix microLED display with a resolution of 48 x 36 monochrome pixels using its native technology capability and a new pixel architecture that improves light extraction. The roadmap for this platform includes the development of higher resolution displays up to 128 RGB x 128 (or 384 x 128 monochrome) by the end of 2020. The Data-Vµ passive matrix displays are designed to be driven from a driver IC, requiring no active matrix backplane. The drive architecture along with its small form factor makes the Data-Vµ passive matrix displays an ideal and cost-effective solution for AR smart glasses and head-mounted displays for navigation, sport & leisure, wearables and optical instruments where dynamic content can be displayed.
