LIQUID CRYSTAL DISPLAY AND DRIVING CIRCUIT THEREOF

摘要

An LCD device and a driving circuit thereof are provided to improve display error due to the resistance deviation of a fan out unit by applying compensated driving signals to compensate for the variation amount of a voltage level of the driving signals. An LCD(Liquid Crystal Display) device includes an LCD panel(300) and drivers(400,500). The LCD panel includes a unit pixel, a display unit having signal lines connected to the unit pixel, a pad unit having a signal pad for connecting the drivers to the signal lines, and a fan out unit having a fan out line for connecting the signal lines and signal pad. The drivers include signal generators(410,510) for generating driving signals required for the operation of the unit pixel and signal compensators(420,520) for compensating the driving signals to have a voltage level in proportion to the length of the fan out line.
