前記液晶パネルの電源投入時に、電源の立ち上がりに同期して前記ゲートドライバにリセット信号を供給し、前記ゲートドライバの全出力端子をオフ状態にし、前記ゲートドライバに入力される操作開始信号の立ち上がりに同期して前記リセット信号の供給を解除し、前記ゲートドライバの全出力端子を通常動作状態に戻すパワーオンリセット回路を備えることを特徴とする液晶パネルの駆動回路。 Via the source driver supplies the display data to the display data lines of the liquid crystal panel, a driving circuit of the liquid crystal panel you supply an operation signal through the gate driver to the scanning lines of the liquid crystal panel,
At power-on of the liquid crystal panel in synchronization with the rising of the power supply a reset signal to the gate driver, all output terminal of the gate driver is turned off, the rising of the operation start signal inputted to the gate driver synchronously to release the supply of the reset signal, the drive circuit of the liquid crystal panel, characterized in that it comprises a power-on reset circuit to return the total output of the gate driver to the normal operation state.
