Abstract
A discharging control circuit and method thereof is provided for a liquid crystal display (LCD). The discharging circuit includes a signal-off detector and an all-gate-on delay cell. When a LCD off signal is detected, a first control signal is transmitted to a power supply module for turning off power except that supplying gate-on voltage, yet turning off VGH as well after a specific delay time. A second control signal is also transmitted to the gate-on-delay cell, so that all gates of the pixel transistors are turned on after a second specific delay time. Electronic charges on the pixel transistor are discharged via a source thereof before the gate-on voltage decreases below a threshold value, such that a residual image phenomenon that is caused by heterogeneous filming fabrication is eliminated.
