Plessey, an embedded technologies developer at the forefront of microLED technology for augmented and mixed reality (AR/MR) display applications, has added passive matrix microLED displays to its Data-Vµ product family.
Following the successful 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 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 customised to provide the specific resolution and colour 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.
Leon Baruah, Plessey’s Senior microLED Product Sales Manager, commented:
“MicroLED displays are now the go-to technology for next-generation developments requiring power-efficient and ultra-bright displays. With the introduction of our Data-Vµ passive matrix displays, applications, where dynamic content needs to be displayed in a small form factor that is outdoor readable without compromising on battery life, has become reality.”
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.
