IMPLEMENTATION OF DRIVE OF TOUCH FLAT PANEL DISPLAY |
摘要 |
A touch flat panel display includes a display screen and a driving circuit; output ends of a display driving circuit in the driving circuit are respectively connected with electrode lines of the display screen through units of a display/touch signal gating-switch and output circuit or a display/touch signal loading and merge circuit. The units of the display/touch signal gating-switch and output circuit or the display/touch signal loading and merge circuit are connected with a touch excitation source through one or more circuit paths; the display/touch signal gating-switch and output circuit or the display/touch signal loading and merge circuit enables more than two electrode lines of a display screen to simultaneously communicate with the touch excitation source for providing touch excitation energy; and the touch system circuit time division detects changes of touch signals on a circuit path connecting the touch excitation source with the electrode lines of the display screen.
