  • Patent number: 7429970
    Abstract: A method of testing a drive circuit including a scan line drive circuit and a data line drive circuit for driving a display is disclosed. The display may include a plurality of scan lines and a plurality of data lines, each of said scan lines including an initial terminal coupled to said scan line drive circuit, each of said data lines including an initial terminal coupled to said data line drive circuit. The method includes: coupling each of said scan lines and each of said data lines to a first testing pad and a second testing pad respectively; sending a first testing signal to an input terminal of said scan line drive circuit and sending a second testing signal to an input terminal of said data line drive circuit; and testing at said first testing pad and said second testing pad respectively.

  • Patent number: 7268754
    Abstract: A pixel testing method is provided. The pixel testing method is adapted to measure device parameters within each pixel of a display. Before plating a lighting device into each pixel, a capacitor is formed such that one end of the capacitor is connected to an open-circuit terminal of an electronic device while the other end of the capacitor is connected to an added common line (or the original scan line or data line of the display). The parameters of the electronic device connected to the lighting device are tested through a charging/discharging of the capacitor so that all the devices within a pixel can be tested before forming organic functional layer in every pixel.

  • Patent number: 7123043
    Abstract: A method and an apparatus for testing a plurality of driver circuits of an AMOLED before OLEDs are implanted are provided. The method and the apparatus select one specific driver circuit to be tested and dispose a conductive board above the array glass of the OLED to form a capacitor. By using the data line, the scan line, and the power line of an AMOLED, the present invention is able to input and retrieve signals from driver circuits for analyzing each of them is normal or not.
