The double pixel clock or 24-bit color depth can generally be taken from the datasheet. There are two
interface modes existing at 24-bit color depth:
FPDI (Flat Panel Display Interface) or LDI (LVDS Display
Interface). Some panels use the line SELL LVDS (SELect Lvds data order). The LVDS data assignment in the
datasheet can give you an indication by the last channel (e.g. RX3/TX3 – SELL LVDS = low) wether it is a LDI
panel (contains the lowest bits). Most panels have a FPDI interface.
Example:
FPDI data assignment (LVDS channel 3 even or odd):
Tx/Rx27 Red 6 (e.g. even: RE6 or ER6)
Tx/Rx5 Red 7
Tx/Rx10 Green 6 (e.g. even: GE6 or EG6)
Tx/Rx11 Green 7
Tx/Rx16 Blue 6 (e.g. even: BE6 or EB6)
Tx/Rx17 Blue 7
Tx/Rx23 not used
LDI data assignment (LVDS channel 3 even or odd):
Tx/Rx27 Red 0 (e.g. even: RE0 or ER0)
Tx/Rx5 Red 1
Tx/Rx10 Green 0 (e.g. even: GE0 or EG0)
Tx/Rx11 Green 1
Tx/Rx16 Blue 0 (e.g. even: BE0 or EB0)
Tx/Rx17 Blue 1
Tx/Rx23 not used
