Driving module for a liquid crystal display panel and a liquid crystal display device having the same

Abstract

Disclosed are a driving module for a liquid crystal display panel and a liquid crystal display device capable of inspecting the effectiveness of a driving signal applied to a display cell circuit of the liquid crystal panel and a wiring state of driving signal input/output lines. The display cell circuit provided in the liquid crystal display panel is connected to a gate line and a data line. The liquid crystal display panel displays an image in response to gate and data driving signals inputted through the gate and data lines. An integrated printed circuit board generates gate and data driving signals. A data driving module is electrically connected between the integrated printed circuit board and the data line to control the time for applying the data driving signal. A gate driving module has a plurality of gate driving signal input/output lines connected to the gate line. The gate driving module provides the gate driving signal to the gate line by controlling the time for applying the gate driving signal and inspects the states of the gate driving signal and the gate driving signal input/output lines. The wiring state of the gate driving signal input/output lines, which are formed in the integrated printed circuit board by passing through the gate driving module, and the effectiveness of the driving signal supplied to the gate line through the gate driving signal input/output lines can be easily inspected.
