ABSTRACT:
A display circuit for a matrix display includes a plurality of picture elements comprising display elements driven by drive circuits. A data regenerative circuit determines whether an external video signal is to be displayed or whether the image being displayed by the picture elements is to be held. When the image currently stored in the picture elements is to be held, the data regenerative circuit reads the stored image data from a selected picture element, regenerates the level of the data signal and causes this data to be rewritten into the selected picture element.
