Following the launch of Plessey’s Data-Vµ segmented Micro LED display products in 2019, the company has now extended the range with the introduction of passive matrix pixelized Micro LED displays, based on Plessey’s proprietary monolithic GaN-on-Silicon technology.

These fully addressable micro-displays can 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 required by customers to present dynamic content specific to their applications. These applications can take advantage of the high brightness and contrast inherent in Plessey’s Micro LED technology to produce visual images, which can be viewed under a wide range of environmental conditions and at low power consumption.

Plessey has demonstrated its first monochrome passive matrix Micro LED 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 a 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.
