A near-eye display device (100, 400) includes a display panel (102, 408, 410) with an array of photon-emitting cells (111, 112, 113, 114, 115) interspersed with photon-detecting cells (121, 122, 123) and a display controller (208) coupled to the display panel, the display controller to control the display panel to display imagery using the array of photon-emitting cells. The device further includes a camera controller (210) coupled to the display panel, the camera controller to control the display panel to capture imagery of an eye (108) of a user using the photon-detecting cells. The device also includes an eye-tracking module (214) coupled to the camera controller, the eye-tracking module to construct a three-dimensional representation (806, 906) of the eye based on the captured imagery.
