Liquid crystal display

摘要

A liquid crystal display (LCD) device includes: a liquid crystal panel including gate lines and data lines crossing to define a plurality of pixels; a timing controller for generating a gate control signal and a data control signal for driving each pixel by using signals inputted from a system and realigning pixel data from the system to output the same; a gate driver for driving the gate lines by using the gate control signal; a data driver for supplying pixel data to a corresponding data line according to the gate control signal; and a reset signal generating unit for generating a reset signal upon receiving input power from the system, and supplying the reset signal to the timing controller, wherein the reset signal generating unit includes: a first resistor connected to an input power input terminal to which input power is applied from the system; a Zener diode having a cathode connected to the first resistor and forming a first node between the cathode and the first resistor; a second resistor connected between an anode of the Zener diode and a reset signal output terminal; a third resistor connected between the reset signal output terminal and a ground; and a capacitor connected between the first node and a ground.
