LCD controller - Display interface

The STV0684 LCD controller has been specifically designed to ensure the two following important

characteristics:

● Support of low cost panels with a direct interface to digital LCD panels removing the need for an

external timing controller IC

● Flexibility with a high-level of programmability on all the signals shapes, polarities and

frequencies

The display interface fully supports LCD panel dot selection modes such as Delta, Delta

Transverse, Delta Longitudinal and Mosaic and many more by incorporating a dot selector which

converts 3dot/pixel input RGB frame data, to 1dot/pixel RGB data.

Basic functionality of the system includes still picture review, viewfinder mode as well as viewfinder

mode while recording a video clip.
