Sony Semiconductor Solutions Corp. (SSS) will release the ECX344A, a large-size, high-definition 1.3-type OLED Microdisplay with 4K resolution, which will contribute to more realistic recreations of spaces.

The new OLED Microdisplay is mainly intended for virtual reality (VR) and augmented reality (AR) head-mounted display applications. It delivers 4K resolution with a 1.3-type large-size display by employing miniaturization processes that SSS has achieved while developing camera electronic viewfinders (EVFs), as well as its own pixel drive circuits. A new high-speed driver circuit is included in the microdisplay to enable a high frame rate even at 4K resolution, allowing for smooth image quality with an enhanced sense of reality. Moreover, SSS’s original pixel structure makes it possible to achieve both a wide color gamut and high luminance performance.

By providing this new microdisplay, SSS will help support new experiences with VR/AR head-mounted displays that deliver an incredible sense of reality immersion.

Smoother image quality

At higher resolutions and pixel counts, display devices typically show variations in characteristics such as luminance across individual pixels, resulting in image quality degradation. This new microdisplay, however, is made with optimized manufacturing processes and transistor layout, and also features a unique variation compensation circuit. This design helps address transistor characteristic variations, delivering uniform luminance even at 4K resolution to ensure excellent image quality. This new microdisplay also employs a new high-speed driver circuit which delivers smooth moving images at a frame rate of 90fps.

Integrating this kind of high-quality performance onto a 1.3-type, large-size microdisplay allows for imaging with wider viewing angles on targeted products

Wider color gamut and higher luminance

With conventional technologies, there was a tradeoff between color gamut and luminance performance, but the new microdisplay solves this by employing an original pixel structure that offers improved light-use efficiency while still expanding the color gamut. This design enables not only a wide color gamut that covers 96% of DCI-P3 color space but also a high luminance level, delivering a more immersive experience with realistic images when combined with high-definition pixel design.
