INSTRUMENT FOR AUTOMATED TESTING OF DISPLAYS

摘要

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.

1. An apparatus for testing displays, comprising:
a frame; a display sled including a mount for holding a display under test (“DUT”), wherein the display sled is supported by the frame and moves between a test position and a load position; a lamp source supported by the frame and positioned to illuminate the DUT when the display sled is in the test position; a measurement camera 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 to generate the one or more test images to drive the DUT; an electrical interconnect to temporarily establish an electrical connection between the driver circuitry and the DUT when the display sled is in the test position; and an actuator coupled to physically manipulate the electrical interconnect to engage or disengage the electrical connection between the driver circuitry and the DUT.
