New title: Sony releases 1.3-inch 4K OLED micro display, designed for AR/VR scenes

Sony launched a micro-OLED display called ECX344A on August 24. The display is mainly used in the fields of augmented reality (AR) and virtual reality (VR), with 4K resolution and 90Hz refresh rate. And covers 96% of the P3 color gamut

Officially stated that this ECX344A display adopts the "miniaturization process" achieved by Sony when developing its camera EVF (electronic viewfinder), thereby cramming 4K resolution and 90Hz high refresh rate into a 1.3-inch space. efficiency, achieving "smooth and crisp image quality." In addition, Sony also claims that the unique pixel structure of this screen can also achieve "excellent wide color gamut and high brightness performance" and help "support new experiences of VR/AR head-mounted displays"

Sony said that when observing the surrounding scenery in a virtual space, delay and residual images can interfere with immersion and make "the brain feel like something is not where it is." To deliver smooth, clear graphics and minimal image retention, this tiny display can deliver peak high brightness levels of 5000 cd/m² and normal brightness of 1000 cd/m², ensuring reasonable brightness and the ability to reduce Afterimage

IT House found that this micro display provides three display modes. Sony claims that third-party manufacturers can choose based on "application circumstances"

• Normal mode: 4K resolution input data.
• Upscaling mode: Interpolates input data at 2K to 2.5K resolution to 4K resolution for display, thereby reducing the load on the display-equipped device.
• Scan mode: Displays the image in the center of the human visual range at high resolution, similar to the technology used by Sony in PS VR 2, that is, the normal resolution is rendered where the human eye sees it, and the rendering resolution is reduced where the human eye cannot see it. . Sony claims "this helps maintain visual immersion while reducing the amount of data transferred by approximately 60%, easing the workload on image processors on products using tiny displays".
