Abstract:
A test apparatus includes a display sled having a mount for holding a display under test (“DUT”). The display sled is supported by a frame and moves between a test position and a load position. A lamp source is supported by the frame and positioned to illuminate the DUT when the display sled is in the test position. A measurement camera is supported by the frame and positioned to capture one or more test images output by the DUT when the DUT is illuminated by the lamp source. Driver circuitry generates the one or more test images to drive the DUT. An electrical interconnect establishes an electrical connection between the driver circuitry and the DUT when the display sled is in the test position. An actuator is coupled to physically manipulate the electrical interconnect to engage or disengage the electrical connection between the driver circuitry and the DUT.
