Parallel to LVDS Encoder
|
|
||||||
------------------------
|
|
||||||
|
|
||||||
This binding supports the parallel to LVDS encoders that don't require any
|
|
||||||
configuration.
|
|
||||||
|
|
||||||
LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
|
|
||||||
incompatible data link layers have been used over time to transmit image data
|
|
||||||
to LVDS panels. This binding targets devices compatible with the following
|
|
||||||
specifications only.
