240x400 Parallel Color TFT
Part Number: CFAF240400D-T
This display module is a 3 inch diagonal, 240xRGBx400, full color TFT LCD display. It has a wide-screen format and white LED backlight. Its integrated controller gives you a simple, fast, digital interface to the display through your 3v processor's port pins. It may be used in either portrait or landscape orientation. In portrait mode, the narrow width of the TFT display works well with portable, handheld, or embedded systems. In landscape mode, the low profile of the TFT LCD display may be used for the user interface of 2U+ rack mount devices, or in bench top laboratory equipment such as power supplies, meters, and signal generators.
- 240xRGBx400 Full color graphic TFT module
- Built-in Orise Tech SPFD5420A or compatible controller
- 18/16/8-bit parallel interface
- Wide Temperature Range
- RoHS Compliant

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.
