Displays with Reduced Driver Circuit Ledges

摘要

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.

1. An organic light-emitting diode display comprising:
a transparent display layer; a thin-film-transistor layer having a substrate with first and second opposing surfaces and thin-film-transistor circuitry formed on the first surface; and a display driver integrated circuit mounted to the second surface, wherein the transparent display layer overlaps the display driver integrated circuit, and wherein the substrate has conductive vias that pass through the substrate from the first surface to the second surface and that couple the thin-film-transistor circuitry to the display driver integrated circuit.
