2.8 Inch 480×480 Round TFT Display 350nits With HDMI Board
The Hicenda 2.8 inch round TFT display is a 2.8 inch circular a-Si TFT LCD module with 480×480 resolution, 350 cd/m² brightness and a 262K color range, driven by the ST7701S IC over a 3SPI + 18RGB interface on a 40-pin 0.5 mm pitch connector. With an all-direction viewing angle, a slim 73.03×76.48×2.34 mm outline and a -20℃ to +70℃ operating range, it drops neatly into round-faced products where a rectangular panel would look out of place. Choose the bare module, or the version bundled with an HDMI driver board so you can feed it video straight from a PC, mini PC or single-board computer without writing display firmware first.
Features
- True round 480×480 panel — a 2.8 inch circular active area of 70.13×70.13 mm keeps dials, gauges and watch-style UIs sharp and perfectly framed.
- 350 cd/m² with 262K colors — an LED backlight and normally black a-Si TFT structure hold contrast and readability in bright indoor and semi-outdoor light.
- Flexible ST7701S interface — 3SPI + 18RGB over a 40-pin 0.5 mm pitch FPC connects easily to common MCU and SoC platforms.
- Industrial temperature range — rated -20℃ to +70℃ operating and -30℃ to +80℃ storage, in a 2.34 mm thin outline for tight enclosures.
Applications
Smart home controllers and thermostats, automotive and motorcycle dashboards, industrial instruments and HMI panels, outdoor and portable equipment, round smart watches and wearables, medical and test devices, and HDMI-driven demo or signage builds when paired with the HDMI board option.
