USB LCD Displays
240x400 3" Full Color TFT LCD
Part Number: CFAF240400D-030T
This 3.0" diagonal, 240x400 pixel, full RGB color graphic TFT display module boasts a 38.88mm x 64.80mm active area.
- Four parallel interface modes are available: 8-bit, 9-bit, 16-bit or 18-bit.
- The integrated Orise OTM4001A 720-channel 6-bit source driver or compatible controller, allows a single 3.3v supply for both power supply and logic.
- The 12:00 o'clock viewing direction (polarizer viewing direction) is ideal for products viewed at or below eye level.
- Measuring 45.03 x 77.00 millimeters overall with the FPC folded, you can mount this display in portrait or landscape orientation.
- In portrait orientation, the narrow width of this TFT works well with portable, handheld, or embedded systems.
- In landscape orientation, the low profile of this TFT may be used for the user interface of 2U+ rack mount devices or in benchtop laboratory equipment such as power supplies, meters, and signal generators.
- For mass production, the display's tab makes fast and easy connection possible using a hot bar soldering machine.
- Temperature operation is from -20°C to +70°C.

Additional Options
As an option, you can order this TFT pre-assembled onto a breakout/carrier board. The board allows easy prototyping through its 0.1" headers. You can also include the carrier board in your end product to simplify construction and assembly. The carrier board contains a constant-current switching LED driver. The PCB is sized to fit neatly within the outline of the display.
This kit is available with or without standoffs in the four mounting holes. The standoffs allows the carrier board to be mounted using any 2-56 style screw. The standoffs are 3mm deep to ensure sturdy mounting points.

Product Notes
This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail. The TAB connector is soldered directly to corresponding pads on your PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost. The TAB style connection requires no separate connector, so the cost is very low, and the ultra thin profile of the display is maintained.
