Always-on Mobile Displays
Prototype built in partnership with Samsung Advanced Institute of Technology
Type: Replacement for LTPO pixel architecture used in Apple Watch
Benefits Compared to LTPO:
- 15% lower cost
- Higher brightness
- Longer Battery Life
- Gen8+ compatibility (Gen6 for LTPO)
- Variable refresh rate (always-on) with low current leakage
Technology
- Bottom emission
- Frontplane: RGB (FMM)
- Backplane: Oxide sw-TFT + OLET (Mattrix’s organic light-emitting transistor)
- Further cost savings: Fewer process steps enable increase in manufacturing substrate size from Gen6 (LTPO) to Gen 8+
