Oled display with locally transmissive polarizer

A device, comprising:

• a display panel comprising an array of pixels extending in a plane of the display panel, each pixel comprising an organic light emitting diode (OLED) arranged to emit light to a front side of the display panel;
• an absorptive polarizing layer arranged between the array of pixels and the front side of the display panel, the absorptive polarizing layer comprising a first area that transmits substantially all of a first polarization state of visible light incident thereon in a direction normal to the plane of the display and absorbs substantially all of a second polarization state of the visible light, the first and second polarization states being orthogonal polarization states, the absorptive polarizing layer further comprising a second area that transmits more than 50% of unpolarized visible light incident thereon in the direction normal to the plane of the display, and a third area located between the first area and the second where the polarizing layer's transmission decreases monotonically from the second area to the first area;
• and
• a sensor arranged on a back side of the display panel opposite the front side, the sensor configured to receive light transmitted through the second area of the polarizing layer.
