Abstract
Electronic devices having a display stack that includes LED light sources combined with at least one other component layer are described. In some instances, the LED light sources are coupled to a dedicated touch sensor circuit layer, which removes an entire layer from the display stack. The touch sensor circuit layer can be installed with an addition portion of flexible printed circuitry extending the length of a lightguide and the LEDs can be installed on that flex. In other instances, particularly when the touch sensor layer is deposited directly on the interior surface of the cover glass, the LEDs can also be mounted to the glass itself, thereby potentially eliminating two layers from the display stack. While the elimination of any layers within the display stack enable the display stack to have a reduced thickness, there also are significant improves as a result of the elimination of the layers because there is a similar elimination of one or more flex printed circuits that must dealt with during the final assembly process of the electronic device itself.
