Abstract:
1. A Liquid Crystal Display (LCD) device comprising: a driver comprising at least one gate driving IC for outputting a scan signal to a plurality of gate lines of a panel, and at least one data driving IC for respectively outputting a plurality of image data signals to a plurality of data lines of the panel; and a timing controller that determines whether a current mode is an abnormal mode in which the panel outputs an abnormal image by using at least one lock signals, wherein the timing controller: when the current mode is determined as the abnormal mode, outputs a masking control signal as a reference signal to the driver which blocks the driver control signal outputted to the gate driving IC, thus prevents the LCD panel from displaying the abnormal image, wherein the determining of an abnormal mode comprises the timing controller: selects a lock signal, which is used as determination information for determining whether the current mode is the abnormal mode, from the lock signals; generates a detection clock on the basis of a clock signal and first information which is outputted by the selection; performs an initialization according to the detection clock, and counts the number of frames; compares the number of counted frames with the predetermined number of gate delays to generate second information necessary for determining whether to mask the driver control signal as the masking control signal; and
