1. A method of controlling illumination of a display having non-transparent pixels and transparent pixels that define a transparent area of the display behind which a camera is positioned, comprising:
driving the non-transparent pixels at a first brightness;
driving the transparent pixels at a second brightness greater than the first brightness during a first portion of a video display frame in which the camera is not performing image capture, using gate lines that respectively extend from opposite sides of the display towards each other into the transparent area and using a source line, the gate lines electrically isolated from each other in the transparent area, the gate lines and the source line comprising transparent material in the transparent area and non-transparent material outside the transparent area, and the gate lines and the source line having respective terminating ends located in the transparent area and that comprise the transparent material in the transparent area; and
disabling the transparent pixels during a second portion of the video display frame in which the camera is performing image capture.
