Key Features
- 8.2" circular active area (Φ208 mm): suits dials, gauges, and compact round interfaces
- 1080×1080 resolution, 131 PPI, 16.7M colors: sharp, evenly detailed images across the circle
- 500 nits typical brightness (400 min): clear in bright indoor and well-lit environments
- Wide viewing angle: 85° on all four sides (typ), with a 1000:1 minimum contrast ratio
- 4-lane MIPI DSI with FT8201P driver IC: high-speed, low-pin-count connection via a 40-pin FPC
- On-cell capacitive touch (I²C): the touch sensor is built into the display cell, so no separate touch overlay is needed. This keeps the module thin and simplifies assembly. 1.8 V I²C with INT and RST signals
- Thin 4.0 mm profile: fits space-limited product designs
- Wide temperature range: −20 °C to +70 °C operation
- Two purchase options: bare panel, or with a MIPI-to-HDMI driver board
- RoHS compliant, with ESD immunity of ±4 kV contact / ±8 kV air
