Samsung and LG are both investing in OLEDoS and LEDoS microdisplay technology development

According to foreign media, Samsung Display and LG Display are both developing silicon OLED (OLEDoS) and silicon LED (LEDoS) technologies, which are micro-display technologies designed to be applied to virtual and augmented reality devices.

A similar technology is liquid crystal on silicon (LCoS), which makes displays about 1 inch in size from silicon substrates, unlike traditional displays that use glass substrates. Using silicon substrates to make displays can achieve ultra-high resolution, even if they are small.

For now, Japan's SONY is still the leader in OLEDoS technology, which uses white OLED and red, green and blue filters. Samsung Display plans to provide OLEDoS with a resolution of 3,000 pixels per inch (PPI) and brightness of 10,000 nits to its parent company Samsung in 2024.

For the LEDoS technology, Samsung is aiming for a resolution of 6,000 to 7,000 per inch. In contrast, OLEDoS is for virtual reality devices, while LEDoS is for augmented reality devices.

LG Display previously developed LEDoS for Apple, but recently started developing LEDoS technology as well. The company's OLEDoS is expected to be used in Apple's first mixed reality device coming out next year.Currently, the OLEDoS on the inside of the device are provided by SONY and the screen on the outside is provided by LG Display.
