In accordance with the present invention, a first shorting bar drives the data lines of a TFT array having integrated gate driver circuitry. Another set of shorting bars drive the corresponding terminals of the gate driver circuitry. The pixel voltages are measured after all the pixels are charged by the driving signals applied to the shorting bars. Gate voltages are progressively applied to the gate lines by the gate driver integrated circuit (IC) via the set of shorting bars that, in turn, are driven by clock signals received from one or more pattern generators. Voltages are concurrently applied to the data lines which are connected together by the first shorting bar. The application of voltages generates a display pattern that is subsequently compared to an expected display pattern. By comparing the resulting display pattern and the expected display pattern, possible defects are detected.
