Functional Description
STV0684
3.8 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.
