4 Inch 720x720 Round TFT Display – 800 Nits High Brightness, Optional HDMI Driver Board
4 Inch 720x720 Round TFT Display – 800 Nits Sunlight-Readable Version
Need a round screen that stays clear under bright light? This 4-inch round IPS TFT display delivers 800 nits of brightness at 720x720 resolution. It is a high-brightness upgrade for products used near windows, outdoors or in well-lit retail spaces, where standard round displays look washed out.
Pick the configuration that fits your project:
- Bare LCD panel [MIPI DSI / RGB: confirm] for custom hardware and embedded designs
- LCD + HDMI driver board for plug-and-play use with Raspberry Pi, mini PCs, Windows, and Android devices, with no interface development needed
Its all-round viewing angle and slim round profile suit smart gauges, wearable-style devices, instrument clusters, smart home controllers, appliance panels, and digital signage.
