Abstract:
1. A method for testing a liquid crystal display, comprising: placing a liquid crystal panel on a stage, wherein the liquid crystal panel includes a plurality of data pads on each of a plurality of vertical blocks of the liquid crystal display, a plurality of test data pads connected to the data pads, a plurality of dummy common data lines through which each of the test data pads is commonly to two or more of the data pads, a plurality of gate pads on each of a plurality of horizontal blocks of the liquid crystal display, a plurality of test gate pads connected to the gate pads, a plurality of dummy common gate lines through which each of the test gate pads is commonly to two or more the gate pads; generating a plurality of test pattern signals and a plurality of scanning signals; sequentially providing the scanning signals to the test gate pads of the horizontal blocks of the liquid crystal panel; and providing the test pattern signals respectively to the test data pads of groups of at least two of the vertical blocks of the liquid crystal panel in synchronization with each of the scanning signals.
