METHOD AND CIRCUIT FOR DRIVING PICTURE DISPLAY DEVICES

摘要

A display device with a dot matrix of pixels which allows displaying pictures with any desired number of pixels in cases where picture signals of any given resolution are being displayed using such a display device. Each time one horizontal cycle of picture data is being loaded into the display device, identical picture signals are displayed in one or more lines, and pictures based on the picture signals are displayed at various vertical magnification factors by periodically varying the number of lines with identical signals, while varying the horizontal magnification factor in synchronization with the vertical magnification factor.
