APS Holdings has developed a 3000ppi OLEDoS screen dedicated to AR/VR

APS Holdings, a South Korean display and semiconductor equipment manufacturer, has announced the development of an OLED-on-silicon (OLEDoS) screen with a resolution of 3000ppi. This is a significant advancement from the 1000ppi OLEDoS screen the company released earlier this year.

OLEDoS technology deposits OLEDs on silicon wafers, making it ideal for use in augmented reality (AR) and virtual reality (VR) devices. The 3000ppi OLEDoS screen from APS Holdings uses an RGB emissive layer, while other companies developing OLEDoS use white emissive layers with RGB color filters.

The high resolution of the OLEDoS screen allows for a more immersive and realistic AR and VR experience. It also allows for more detailed and accurate visuals, making it ideal for use in a variety of applications such as gaming, education, and medical training.

In addition to its 3000ppi OLEDoS screen, South Korean company APS Holdings has also been working on the development of fine metal masks (FMMs) for the production of ultra-high resolution OLEDoS. Its subsidiary APS Materials is responsible for the deposition and packaging processes at a facility in Cheonan.

The company has previously stated that there are limits to the resolution achievable with traditional etching methods, which is why it is developing FMMs that use laser patterning instead. The FMM for the 3000ppi OLEDoS screen is made of Invar and has a thickness of just 8 microns, much thinner than FMMs used for OLEDs in QHD smartphones, which are 18 microns thick.

APS Holdings has even bigger plans for the future, as it aims to increase the resolution of OLEDoS to 4000ppi. This is part of a government-backed project to develop prototypes of 4,000ppi AR glasses by 2024. It's clear that APS Holdings is dedicated to pushing the boundaries of display technology and will continue to innovate in the AR and VR industry.
