Video display device

Abstract

A video display device is capable of performing a high-speed switching process and preventing video flicker from occurring. The video display device comprises a plurality of display units including a plurality of unit cells. The unit cell comprises a plurality of dots arranged vertically and horizontally each other and divided into a plurality of dot groups. Each dot is comprised of a plurality of display elements. Further, each unit cell is provided with a plurality of memories, a driving means and a switching means. The memories store the video data to be supplied to display elements. The driving means reads the video data corresponding to said dot groups stored in one of the memory and drives the display elements of said dot groups based on the read video data. The switching means switches alternately and successively the dot groups. The memories store the video data successively in a one-frame unit or a one-field unit. Since video signal written to the memory in a one-frame unit or one-field unit is read therefrom in the one-frame unit or the one-field unit, the dot groups may be switched at highs speed. Thereby, the video flicker maybe prevented from occurring.
