Claim Text:
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; a first actuator to move the display sled between a test position and a load position, wherein the display sled to receive the DUT while the display sled is in the load position, wherein the DUT electrically couples to contacts of a contact region disposed on the display sled; 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, wherein the first actuator to move the display sled between the test position and the load position includes the first actuator to translate the display sled along a first axis, wherein movement of the display sled along the first axis moves both the DUT and the contact region relative to the lamp source, the measurement camera and the driver circuitry, and moves the DUT into optical alignment with the measurement camera and with the lamp source when the display sled is in the test position; an electrical interconnect to temporarily establish an electrical connection between the driver circuitry and the DUT via the contacts of the contact region when the display sled is in the test position; and a second actuator coupled to physically manipulate the electrical interconnect to engage or disengage the electrical connection between the driver circuitry and the DUT.
