The visible display measures only 2.5" (6.35cm) diagonal, Raspberry Pi NTSC/PAL (Television) TFT Display - 2.5" Diagonal comes with a NTSC/PAL driver board. The display is very easy to use - simply connect 6-15VDC to the red and black wires, then connect a composite video source to the yellow and black wire. There's one little button to adjust the LED backlight brightness up and down.
It will work connected to any analog composite-video output. It will not work with a device that only outputs VGA, HDMI or any other digital video signal.
Please note, these miniature displays are very delicate and require care to avoid ripping the delicate flex connector.
If you received a display where the connector cable has red & black wires going to the composite plug then connect yellow to ground, and white wire to 6-12V
