摘要
PURPOSE: A method for investigating a driver circuit and apparatus thereof are provided to perform investigation and defect recovery of the driver circuit in a liquid crystal display rapidly. CONSTITUTION: According to the apparatus for investigating a driver circuit for liquid crystal display device having a number of gate driving cells(GD1-GDn), a test signal supply unit(34) supplies a test signal to the gate lines in parallel. A latch control unit latches the test and start signals to each gate driving cell. A signal branch unit replaces the test signal supplied to the gate lines with signals latched to the gate driving cells. And a detection unit detects each enable state of the gate lines.
