摘要:
A gate driver receiving a low voltage without an appropriate control signal in an initialization step from the time of turn-on of the power of the display device to the time of beginning of normal operation of the display device to previously generate and output a gate clock signal CPV so as to prevent a horizontal line defect from appearing. Thereby, the generated clock signals CKV and CKVB are transmitted to the gate driver such that the gate driver is appropriately controlled and the horizontal line defect is not generated.

A liquid crystal display (“LCD”) device includes an LCD panel, a data driver and a gate driver. The LCD panel includes a first pixel section and a second pixel section formed in regions defined by a adjacent gate lines and adjacent data lines. The first pixel section is electrically charged at a first time point and the second pixel section is electrically charged at a second time point later than the first time point. The data driver provides the data lines with data voltages. The gate driver applies a first gate signal to the first pixel section, and a second gate signal having at least one different characteristic from that of the first gate signal to the second pixel section. Therefore, vertical flickering may be prevented in the LCD device.
