South Korea’s two leading display makers Samsung Display Co. and LG Display Co. are in the early stages of developing screens for extended, or virtual reality devices.
Now they are accelerating their push into the burgeoning market after Google Inc. unveiled its virtual reality (XR) headset Vision Pro equipped with Sony Corp.’s organic light-emitting display (OLED) early this year, according to industry officials on Friday.
Samsung Display is preparing to produce OLEDoS, or OLED on silicon, next year as its affiliate Samsung Electronics plans to launch its first XR device in December 2024.
If it goes as planned, it will become the first South Korean company to produce OLEDoS.
At the 2023 Digital Media Tech Show in Goyang Nov. 2 To secure Samsung Electronics Co.'s semiconductor processing technology, Samsung Display recently paid 39.1 billion won ($30 million) to use its patented semiconductor technology.
OLEDoS refers to OLED made on silicon, not on glass, unlike conventional OLED panels. It is ultra-small with a diagonal length of about 3.3 cm.
The display features a higher pixel density than conventional displays, meaning an enhanced resolution even on a small and lightweight screen.
Microdisplays produced in this way display a screen enlarged tens to hundreds of times close to the eyes.
The XR device market is predicted to grow to 187 million units by 2029. That compares to 21.4 million units in 2023, a 56% jump from the previous year, according to research firm Omdia.
Samsung Display’s first-generation OLEDoS will adopt a WOLED-CF architecture, which uses a white OLED emission layer with filters in red, green and blue.
It will then develop a next-generation OLEDoS in collaboration with the US-based OLED microdisplay developer eMagin, which it acquired at $218 million in May of this year.
LG DISPLAY
LG Display has joined forces with SK Hynix Inc. to develop OLEDoS wafers for XR devices. LX Semicon Co., a fabless semiconductor designer, is in charge of the wafer designs.
LG Display in January unveiled a prototype of OLEDoS mounted on XR headsets at CES 2023, the world’s largest IT and home appliance exhibition.
It is known that LG has no immediate plan to commercialize it.
IN SHORT SUPPLY
OLEDoS for Google Vision Pro was designed by Sony and produced by TSMC, the world’s largest semiconductor foundry company.
Market observers say displays for XR devices are in short supply because they require ultra-fine processes in nanometer (㎚) units.
