What would be needed to hook up one of the pixel qi screens
now that they are available for purchase ?
They are a 40 pin lvds connection with an led backlight.
"PQ 3Qi-01 is a 10.1” TFT Liquid Crystal Display module with LED
backlight unit and 40 pin LVDS interface.
This module supports 1024 x RGB x 600 Wide-SVGA (WSVGA) mode and can
display 262,144 colors.
This module also supports two low power modes: a transflective mode with
lower color and a reflective
black and white (64 grayscales) mode. In reflective mode the screens
shows higher resolution at 3072 x
600 pixels, in transflective mode the color resolution is 1024 x RGB x
600, while the black/white/grey
resolution is 3072 x 600. The converter module for the LED backlight is

Main steps to support a display like this:
1) Get a chip for converting OMAP parallel databus to LVDS
2) Make sure you have a power supply capable of delivering the power needed
for the LCD
3) Update the SW driver to support timings of the display (might be you can
just use the standard one and provide valid timings for the panel through
Please search the list (and the BeagleBoard list) for further info with
respect to driving LVDS based displays. This have been discussed several
Good luck - Please don't hesitate to get back in case of further
