Abstract
The invention is directed to a matrix-addressed display device having a matrix-addressed display element such as a liquid crystal element. The device comprises a sampling frequency generator generating sampling frequency signals. By the sampling frequency signals, the serially input video signals are sampled, held and consequently converted serial to parallel. The sampling frequency generator is provided with means for stopping the sampling frequency signal in periods when serial-parallel conversion is not required.
