Plessey Announces 2.5micron Pitch MicroLED Display

News

2000x2000 pixel display is the latest example of the company's monolithic GaN-on-Silicon technology

Plessey, a UK-based microLED developer, has produced a record-breaking 2.5-micron pixel pitch, ultra-high resolution microLED display. The 2000x2000 pixel display is the latest example of the company's monolithic GaN-on-Silicon technology,

Clive Beech, senior director, business development, at Plessey, said: “Pixel pitch is key to the physical size of large field displays and to the resolution of the viewed image. These are key attributes in AR systems. The 2k2k display scale can be realised in a compact physical form factor and the 2.5micron pixel pitch achieves image features with smooth borders and fine detail."

Plessey's GaN-on-Si technology brings many benefits. The low thermal resistance of the silicon substrates allows highly efficient heat extraction resulting in lower junction temperatures with high reliability. The technology also allows impressive energy efficiency, high resolution and unsurpassed contrast. With its similarity to large scale Silicon IC processing the technology can be scaled to progressively larger wafers, improving cost, uniformity and yield and taking advantage of the latest advances in Silicon wafer processing tools of the volume IC industry.

Other recent ground-breaking milestones from Plessey in its monolithic microLED emissive display programme include the success in March of developing a native Green using GaN-on-Si which naturally emits Blue light. Following in May, SID Display Week 2019 saw the world's first monolithic GaN-on-silicon microLED emissive display with an 8-micron pitch bonded to a backplane for a full active matrix.

Plessey's roadmap includes the production of a full RGB display all on one wafer by 2020's Consumer Electronics Show.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
