PLANAR DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the breakdown voltage of a display driving circuit. SOLUTION: This planar display device changes the level of the horizontal blanking period of video signals from video signal sources 11 and 12 by a selected voltage value from a voltage generation circuit 18, samples the voltage by a sampling clock from a timing generation circuit 15, latches it to a signal line driving circuit 21 and displays it corresponding to an aspect ratio on a planar display panel 14 together with scanning signals from a scanning line driving circuit 22.
