4.7 LCD
The LCD is connected via two 15 pin connectors (Hirose DF13-15P-1.25DSA, mating connector:
DF13-15S-xxx). The power supply for the display is also provided through these connectors. The CB4051
board only supports displays with LVDS interface. For displays with digital interface an extra receiver
board is available. There is no support for DSTN displays.
With the LVDS interface it is possible to trigger LVDS displays with a maximum of 18 Bit colour depth
and one or two pixels per clock. For single pixel displays only one connector is necessary. However, if
you want to read the display's EDID data the second connector must be connected.
The display type can be chosen over the BIOS setup. Please contact your sales representative regarding
an appropriate cable to connect your display.
The following table shows the pin description for the first bit ("even" pixel).
