Display Interface
The Pandaboard ES provides two possible options for the usage of the OMAP4460 parallel display
signals. The first option is to use the onboard TFP410 DVI transmitter, whose output feeds an onboard
DVI-D connector. The second option is to use a Display Board plugged into a pair of 20-pin LCD
expansion connectors (J1 and J4). Both of these possible options are discussed in the following
paragraphs. Additionally, a third display option has been added to the OMAP4460 Pandaboard ES. This
option is using a DSI Display Board plugged into connector J7 on the back side of the PCB. See Figure 8
for a diagram of the Pandaboard ES Display Interface options.
