ABSTRACT:
A method for testing a liquid crystal display panel is provided. The gate drivers are integrated onto the panel. The method includes simultaneously inputting a clock signal, an inverted clock signal, and a pull down signal into clock signal, inverted clock signal, and pull down signal input ends of the gate drivers. Simultaneously input a start pulse into the start pulse input end of the gate drivers to simultaneously turn on the gate lines in the selected area and thus simultaneously turning on the pixels in the selected area. At the same time, input test signals to all the data lines. The method of testing liquid crystal display panels disclosed by the present invention may be performed separately by areas, in which the panel is divided into different sub areas and is tested one area at a time.
