Electronic devices with display-integrated light sensors

A display comprising:

• light-generating layers;
• a transparent cover layer;
• an additional layer having conductive traces, wherein the additional layer is interposed between the light-generating layers and the transparent cover layer;
• and
• a light sensor interposed between the additional layer and the transparent cover layer, wherein the light sensor receives light through the transparent cover layer, and wherein the light sensor is electrically coupled to the conductive traces on the additional layer, wherein the light sensor comprises a proximity sensor.

An organic light-emitting diode display comprising:

• a thin-film transistor layer;
• a layer of organic light-emitting material formed on the thin-film transistor layer;
• an encapsulation layer formed on the layer of organic light emitting material;
• and
• a light-sensing component attached to a surface of the thin-film transistor layer.

An electronic device, comprising:

• a display;
• a display-integrated ambient light sensor attached to a layer of the display;
• control circuitry coupled to the display and the display-integrated ambient light sensor, wherein the control circuitry is configured to receive sensor data from the display-integrated ambient light sensor and to control the display using the sensor data;
• and
• a touch-sensitive layer and wherein the display-integrated ambient light sensor is attached to the touch-sensitive layer.
