DFRobot has released a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, optimized for use with single-board computers like the Raspberry Pi and LattePanda.
Although flexible displays are prevalent in smartphones, interfacing them with SBCs is challenging. DFRobot has therefore integrated a dedicated MIPI-to-HDMI driver board to facilitate plug-and-play compatibility across various platforms. The panel’s thickness is just 1.2mm, allowing it to bend and accommodate curved, space-limited designs. It also offers 450 cd/m² brightness and displays 16.7 million colors. Like standard OLEDs, it provides deep blacks and high contrast without needing a backlight, making it ideal for wearables, robotics, and industrial HMI systems.

- Temperature – -20°C to 60°C
This display uses a two-board system to convert a standard HDMI signal to communicate with a smartphone-grade AMOLED panel. The main driver board processes the HDMI input, converts it to MIPI DSI, and supplies power, while the “HDMI_USB_HID” adapter board connects to the panel’s small, high-density connectors. The adapter board primarily addresses the challenge of accommodating the high-density board-to-board (B2B) snap connectors used in smartphones to save space.
A few years ago, the Royole RoKit enabled developers to experiment with a 7.8-inch flexible display and a Qualcomm Snapdragon 660 board using a similar HDMI converter board. DFRobot notes that this display is suitable for industrial HMI panels, automotive curved consoles, robot facial displays, and wearable devices where space and form factor are constraints.
While looking for more details, I found Panox Display, a company specializing in display panels and driver boards. DFRobot’s display is similar to their 6.67inch Flexible AMOLED panel, although their driver board design differs, and it lacks an HDMI board.
