Description

The CFAF480640A-035T with transflective polarizer is a 3.5" sunlight readable, 480xRGBx640 / 640x480xRGB, 262K color, active matrix TFT. It has 6 bright white series LEDs for great visibility in low light conditions, while the transflective polarizer allows great visibility in direct sunlight. It uses the latest in AIFF/MVA technology so the image has high contrast and a wide viewing angle. This 640x480 TFT display is perfectly suited for both indoor and outdoor use.

With an active area of 53.57x71.42mm and a resolution of 640 x 480 (landscape) or 480 x 640 (portrait) pixels, this display has a very high pixel density. The controller in this sunlight readable TFT display is the Himax HX8363-A controller. which uses the standard RGB+SPI interface so you won't run into any trouble getting the display up and running. The logic voltage range of 2.3v to 3.3v was selected to allow direct connection to 3.3v processors.

The 6 white LED series backlight (~19.2v) will typically require a current-controlled boost LED driver. The series LED configuration guarantees perfect current matching across the 6 LEDs. We have an example of a suitable LED driver circuit shown in the schematic of the CFA10065 breakout board. We think you'll be pleasantly surprised to see this display looking great for its expected lifetime of at least 50,000 hours -- longer if you dim or turn off the backlight when not in use.

This display is perfect for situations with changing levels of ambient light from darkness to direct sunlight. Examples include in dash or dash mounted electronics, exterior status displays, cryogenic sleep chambers, and pod bay door controllers.
