Cell test method and liquid crystal display panel for a tri-gate type pixel structure

摘要

A cell test method for a liquid crystal display panel includes the following steps. A waveform sequence to shorting bars is provided, wherein the waveform sequence includes that the first gate line sends a voltage of “turn on” signal and the second and third gate lines send a voltage of “turn off” signal at the first and second time periods; and the waveform sequence further comprises that the first and second data lines respectively send first and second voltages at the first and second time periods, the first threshold voltage is higher than the first voltage, the first voltage is higher than the common voltage, the common voltage is higher than the second voltage, and the second voltage is higher than the second threshold voltage, whereby pixels defined by the first gate line and the first and second data lines is turn on.
