Overview
A 3.99-inch round IPS TFT LCD module with 720×720 resolution, MIPI interface and ST7703I driver IC, developed for smart-home products and embedded devices that need a distinctive circular user interface — the display becomes part of the industrial design rather than just an information window.
Key features
- True circular active area matching round product enclosures.
- 720×720 resolution leaves room for richer circular UI, menus and animations.
- IPS technology with 85° viewing angle in four directions.
- 450 nits typical brightness (360 nits minimum) for clear indoor viewing.
- MIPI interface for high-resolution embedded integration.
