Over at the Display week 2018 Symposium in May, Google and LG will talk about a new 4.3" OLED panel for head-mounted displays. The model has an 18 megapixel resolution, a pixel density of 1443ppi and a refresh rate of 120Hz.
The world’s highest resolution (18 megapixel, 1443 ppi) OLED-on-glass display was developed. White OLED with color filter structure was used for high-density pixelization, and an n-type LTPS backplane was chosen for higher electron mobility compared to mobile phone displays. A custom high bandwidth driver IC was fabricated. Foveated driving logic for VR and AR applications was implemented.
