Abstract:
An electronic device display may have a color filter layer, a thin-film-transistor layer, and a layer of liquid crystal material. The display may have a display cover layer such as a layer of glass or plastic. Adhesive may be used to attach the upper polarizer to the display cover layer. The thin-film transistor layer may have a substrate with upper and lower surfaces. Thin-film-transistor circuitry may be formed on the upper surface. A display driver integrated circuit may be mounted to the lower surface or a flexible printed circuit and may be coupled to the thin-film-transistor circuitry using wire bonding wires. Through vias that are formed through the thin-film-transistor layer substrate may be used in coupling the thin-film-transistor circuitry to the display driver integrated circuit.
Abstract:
A tunable liquid crystal optical device defining an optical aperture and having a layered structure. The device includes a film electrode formed on a surface of a first substrate and covered by a second substrate, and a contact structure filling a volume within the layered structure and contacting the film electrode. The contact structure is located outside of the optical aperture and provides an electrical connection surface much larger than a thickness of the film electrode, such that reliable electrical connections may be made to the electrode, particularly in the context of wafer scale manufacturing of such a device.

Abstract:
An LCD module may include a color filter (CF) layer with pixels, mounted to the first glass panel, for modifying light energy to form a display image. A transistor layer below the CD layer may include a glass panel, conductive pathways, and transistors coupled to the conductive pathways and for controlling the pixels. A control layer is located below the transistor layer and may include a display controller for generating signals to control the transistor. First wire bondings carry the signals between the display controller and the conductive pathways included in the transistor layer. The LCD module may be used in a substantially round device, such as a watch, to provide a substantially borderless display.

Abstract:
A system for providing an electrical interface across a sealed boundary may include a frame in sealed engagement with at least a portion of a substrate. The substrate may be in communication with an electrochromic device. The system may further include first and second conduits. The first conduit may be on a first side of the substrate and a second conduit may be on a second side of the substrate. The second conduit may be in communication with the first conduit through at least one of the seal, a space between the seal and the frame, and a space between the seal and the substrate.
