Abstract:
1. An LCD device comprising: a liquid crystal panel including a plurality of pixel cells formed at every regions defined by a plurality of data lines and gate lines; a gate built-in circuit, built-in the liquid crystal panel, for supplying gate-on voltages to the gate lines; a driving integrated circuit for driving the gate built-in circuit and supplying video signals to the data lines; and a pad region including a plurality of input/output terminals electrically connected to input/output bumps of the driving integrated circuit in the liquid crystal panel, wherein the driving integrated circuit comprises a signal relay unit to relay a source data signal and synchronizing signals from the external driving system through the flexible printed circuit, a first power generating unit to generate a first power, a second power generating unit to generate a second power by using the first power, a signal control unit to align the source data signal supplied from the signal relay unit to be suitable for the driving of the liquid crystal panel, and to control the inside of driving integrated circuit, a control signal generating unit to generate data control signals and gate driving signals for driving the gate built-in circuit by using the synchronizing signals supplied through the signal control unit.
