Abstract: An electronic device includes a stack assembly and a cover glass. The stack assembly includes an electrophoretic display sub-assembly for rendering content, a front light sub-assembly comprising a light guide, a light FPC, and a plurality of light sources, and a capacitive touch sensing sub-assembly for detecting touch inputs. A yellow-pigmented tape is applied over the light sources and an edge of the light guide. A stiffener member is coupled to the light FPC opposite the yellow-pigmented tape.

Abstract: Systems, methods, and computer-readable media are disclosed for borderless display stacks for use with electronic devices. In one embodiment, a display stack may include a thin film transistor (TFT) layer comprising an active area, an electrophoretic layer coupled to the TFT backplane, and an electrode coupled to a perimeter portion of the electrophoretic layer. The electrode may extend beyond peripheral edges of the electrophoretic layer. A portion of the electrode may be positioned between the electrophoretic layer and the TFT backplane, and the electrode may surround the active area. The display stack may include a cover layer coupled to the electrophoretic layer.

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.

Abstract: An electronic device comprises a display stack that includes an active matrix display operable using thin film transistor (TFT) circuitry. The display stack also includes a light guide layer capable of illuminating the active matrix display. A glass substrate of the active matrix display has a first side and a second side opposite the first side, wherein the glass substrate includes the TFT circuitry disposed on the first side and one or more through-glass vias that electronically connect portions of the TFT circuitry disposed on the first side of the glass substrate to one or more electronic connectors or electronic circuitry disposed on the second side of the glass substrate.

Abstract: An electronic device includes a stack assembly and a cover glass. The stack assembly includes an electronic paper display sub-assembly for rendering content, a front light sub-assembly for illuminating the electronic display sub-assembly, and a capacitive touch sensing sub-assembly for detecting touch inputs. The cover glass includes two apertures for the placement of control buttons for the electronic device. Prior to assembly of the electronic device, the cover glass is strengthened after the two apertures are formed so as to strengthen the interior edges of the apertures.
