Display Interface
The PandaBoard provides two possible options for the usage of the OMAP4430 parallel display signals.
The first option (the as-shipped default configuration) routes them to a TFP410 DVI transmitter, whose
output feeds an onboard DVI-D connector. The second option routes them to a pair of 20-pin LCD
expansion connectors (J1 and J4). Both of these possible options are discussed in the following
paragraphs. See Figure 8 for a diagram of the PandaBoard Display Interface. The path shown in red in
Figure 8 is the as-shipped default configuration.

2.12.1 Parallel Display DVI-D connector
As mentioned previously, the as-shipped parallel display interface configuration for the PandaBoard is
with the parallel display interface signals from OMAP driven to a TFP410 DVI transmitter, whose output
feeds an onboard DVI-D connector. See Figure 9 for a block diagram of this interface.
