6.67-inch flexible AMOLED display works with Raspberry Pi, LattePanda, and other SBCs with HDMI output

DFRobot has introduced a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, designed for easy use with single-board computers such as Raspberry Pi and LattePanda.

While flexible displays are common in smartphones, they are difficult to interface with SBCs, so DFRobot added a dedicated MIPI-to-HDMI driver board for plug-and-play compatibility with a wider range of platforms. The panel is just 1.2mm thick and bendable, enabling curved and space-constrained designs, while delivering 450 cd/m² brightness and 16.7 million colors. Like typical OLEDs, it offers deep blacks and high contrast without requiring a backlight, making it suitable for applications ranging from wearables and robotics to industrial HMI systems.

DFRobot 6.67” flexible AMOLED Display specifications:

• Compatibility – Raspberry Pi, Banana Pi, Orange Pi, and most devices with an HDMI output.
• Display Panel
  • Screen Size – 6.67 inches
  • Screen Material – Flexible AMOLED
  • Resolution – 2400 x 1080 (SPR – Sub-Pixel Rendering)
  • Aspect Ratio – 20:9
  • Brightness – 450 cd/m² (Typical)
  • Refresh Rate – 50Hz
  • Viewing Angle – 85°
  • Color Depth – 16.7M colors
  • Active Display Area – 154.56 x 69.552 mm
• Interface – 40-pin MIPI DSI to standard HDMI (via ICNA3511A-based driver board)
• Power Supply – 3.3V – 5V (5V via the driver board for standard SBC integration)
• Dimensions – 162.56 x 74.46 x 1.2 mm
• Temperature – -20°C to 60°C

This display uses a two-board design to convert a standard HDMI signal into something a smartphone-grade AMOLED panel can understand. The main driver board handles the HDMI input, converts it to MIPI DSI, and supplies power, while the smaller “HDMI_USB_HID” adapter board simply bridges the connection to the panel’s tiny, high-density mezzanine connectors. That connector is a high-density board-to-board (B2B) snap connector, commonly used in smartphones to save space, but extremely difficult to work with directly. The adapter board exists mainly to solve this problem.

A few years ago, we noted the Royole RoKit that allowed developers to experiment with a 7.8-inch flexible display and a Qualcomm Snapdragon 660 board using a similar HDMI converter board. DFRobot says the display is suitable for industrial HMI panels, automotive curved consoles, robot facial displays, and wearable devices, where space and form factor are limited.

While searching for more information, I came across Panox Display, a company specializing in various display panels and driver boards. DFRobot’s display appears very similar to their 6.67inch Flexible AMOLED panel, although the driver board design is different, and it doesn’t come with an HDMI board. The company also showcases other products, including rollable OLED displays and a 7.8-inch flexible OLED designed for Raspberry Pi.

The 6.67-inch Raspberry Pi flexible AMOLED display is available on the DFRobot store for $199.00. Volume discounts are also available, dropping the price to $183.00 for orders of ten or more units. The two videos below showcase the 6.7-inch flexible OLED display and the rollable OLED placed around bottles and other accessories. Note that the display can be curved horizontally, but not vertically, as this could damage it.
