Description:

We designed a 1.5-inch, 5009-ppi OLED display with a pixel array and drivers monolithically stacked using an OLED/OS/Si structure (OS: oxide semiconductor). The display also includes IR sensors. The drivers are compatible with foveated rendering, which can reduce power consumption by 51.9%, and incorporate control circuits for achieving this feature.
