CUTAWAY CIRCUIT IN LCD DRIVER SYSTEM AND LCD DRIVER SYSTEM

摘要

A shaping circuit (10) in an LCD driver system, connected to multiple scanline driver circuits (30), comprising: a charging module (11) integrated on a control board (20) for receiving an input of a direct current driving voltage and for outputting a turn-on voltage to charge the scanline driver circuits (30), and multiple discharging modules (12) respectively integrated on each of the scanline driver circuits (30) for controlling the corresponding scanline driver circuits (30) to discharge. The present invention distributes the discharging modules (12) respectively onto each of the scanline driver circuits (30), thus reducing the electric charge of load discharge loaded on the discharging modules (12), and preventing the occurrence of high temperature. As each discharging module (12) is provided with a separate spatial position, component crowding is avoided, and space on the control board is not occupied, thus further facilitating temperature reduction, freeing up space on the control board, and reducing the size of same.
