Abstract
A device for testing flat panel displays includes an interface having compliant bumps mounted thereon, which make electrical contact with pads on the display panel. The interface may have a hole formed therein for allowing the passage of light therethrough when the interface is mounted on the display panel. The compliant bumps ensure that all of the bumps make sufficient electrical contact with the pads.
Claims22
An apparatus adaptable for testing an electric device comprising:
- an interface having electrical paths adaptable for coupling to display test circuitry;
- and
- one or more compliant bumps mounted on said interface and connected to said electrical paths, wherein said one or more compliant bumps are adaptable for making contact with pads on said electric device wherein said electric device is a display panel.
A method for testing a display panel at various stages of manufacture comprising the steps of:
- providing an interface having compliant bumps mounted thereon and electrical paths connected to said compliant bumps;
- providing test circuitry operable for performing one or more test operations on said display panel, wherein said test circuitry is connected to said electrical paths;
- mounting said interface onto said display panel so that said compliant bumps make contact with pads on said display panel, wherein said pads are electrically connected to pixel locations on said display panel.
