An electronic device is provided with a display and a light sensor that receives light that passes through the display. The display includes features that increase the amount of light that passes through the display. The features may be translucency enhancement features that allow light to pass directly through the display onto a light sensor mounted behind the display or may include a light-guiding layer that guides light through the display onto a light sensor mounted along an edge of the display. The translucency enhancement features may be formed in a reflector layer or an electrode layer for the display. The translucency enhancement features may include microperforations in a reflector layer of the display, a light-filtering reflector layer of the display, or a reflector layer of the display that passes a portion of the light and reflects an additional portion of the light.

An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The transparent overlay display is a borderless display in which the active area extends to at least one edge of the display. Data-handling circuitry is arranged within the active area, rather than being arranged along a border of the display. The data-handling circuitry may be fabricated in the active area of the display by fabricating it below opaque pixel regions that generate the display light. This borderless configuration allows partial overlap with the intensified image by eliminating opaque borders in which the data-handling circuitry is fabricated. This borderless configuration helps to minimize size, weight, and power by reducing the size of the display and eliminating the need for bulky beam splitters.
