Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com, July 31 (Xinhua)-- the internal screen technology of Apple's Vision Pro has triggered fierce competition in the display industry, with several Micro OLED manufacturers competing for Apple orders. According to Ji WeChat, supply chain sources revealed that LG Display has successfully entered Vision Pro's silicon-based OLED (Micro OLED) supply chain, becoming the second supplier after Sony. The addition of LG Display breaks Sony's monopoly in the silicon-based OLED field and provides Apple with more options and bargaining space.

The Vision Pro is a high-end augmented reality (AR) product launched by Apple this year, with two built-in Micro OLED monitors, each the size of a postage stamp, with ultra-high resolution and pixel density, reaching 3600mm 3200 and 3386PPI. Such a display can make users feel like they are in a virtual world, which is clearer than a 4K TV. CTOnews.com noted that the Vision Pro screen also supports a variable refresh rate (usually 90Hz), which can be automatically adjusted according to different video frame rates to improve the viewing experience.

The Vision Pro inner screen adopts the relatively mature WRGB Micro OLED technology scheme at present, that is, the full-color display is realized by white OLED and red, green and blue color filters. However, this scheme also has some shortcomings, such as the color filter will reduce the light transmittance, resulting in the lack of brightness of the inner screen. And the WRGB Micro OLED also has to pass through the Vision Pro three-lens lens, the brightness will be further lost.

To solve this problem, Apple uses Tandem to increase the brightness of the WRGB Micro OLED, that is, two WRGB Micro OLED devices are superimposed together to form a highly efficient device structure. However, this will also increase the power consumption, which is not conducive to the extension of battery life.

In order to reduce costs and ensure supply stability, Apple has been looking for more Micro OLED suppliers. In addition to Sonny and LG Display, Samsung display, Vision Technology, BOE and Lakeside are all actively developing Micro OLED technology, hoping to break through technological difficulties and enter the Vision Pro supply chain. Samsung display has made Micro OLED the focus of the next generation of display technology, set up a new micro-display group, and acquired eMagin, an American company called Micro OLED. Samsung says it plans to start operating the Micro OLED production line in the second half of this year and achieve mass production by 2024. Domestic manufacturers such as Vision Technology, Beijing Oriental and Lakeside are also speeding up the research and development of Micro OLED technology to enter Apple's supply chain.

With the continuous progress of technology and the continuous reduction of cost, Micro OLED is expected to achieve large-scale commercial use in the next few years.
