6.8.1 Description<br />
CAP_C_STRUCT 8: LFP Device Descriptor<br />
This block is defined to allow storage of Flat panel Timing information. This is a simple wrapper<br />
and can be viewed conceptually as a virtual EPROM.<br />
6.8.2 Block Elements<br />
6.8.2.1 Interface<br />
Specifies the interface the Display data is to be used for.<br />

6.8.2.2 RawData<br />
It is expected that this block is used to contain one of the following, data formats EDID, Display<br />
ID, UDS, EPI. It is outside the scope of this specification to define the content of this data, please<br />
refer to the relevant specifications.<br />
