Abstract: An apparatus includes a display panel having a first pixel area having a first pixel density and a second pixel area having a second pixel density higher than the first, the panel configured to generate images viewable from a front side and a sensor positioned at the back side arranged to receive incident light transmitted from the front to the back through the first pixel area. The first pixel area has light emitting pixels and signal lines electrically connecting pixel circuits associated with the pixels, and the panel includes a layer having a light blocking material patterned to provide apertures to transmit the incident light between some of the light emitting pixels and the signal lines and to block the incident light from the pixel circuits and the signal lines. Apertures can have different dimensions.
