Each IPU display port (DI) can be connected to each of the
above ports.
7.4.1
LVDS
The LVDS Display Bridge (LDB) connects the IPU (Image
Processing Unit) to an External LVDS Display Interface. There
are 2 LVDS channels. These outputs are used to communicate
RGB data and controls to external LCD displays.
The LVDS ports may be used as follows:
●
Single channel output
●
Dual channel output (one input source, two channels
outputs for two displays)
●
Split channel output (one input source, splitted to 2
channels on output)
●
Separate 2 channel output (2 input sources from IPU).
The output LVDS port complies to the EIA-644-A standard.
