Displays with minimized border regions having an apertured TFT or other layer for signal conductors
First Claim
1. An electronic device, comprising:
- a printed circuit substrate;
a display having a plurality of display layers, wherein a given layer of the plurality of display layers has an opening and wherein the given layer extends around an entire perimeter of the opening; and
a conductive structure that passes through the opening in the given layer, wherein the conductive structure electrically couples circuitry on the given layer to circuitry on the printed circuit substrate.

Abstract
An electronic device may be provided with a display having a thin-film transistor layer. One or more holes in the thin-film transistor layer may be used to form pathways from display circuitry to other circuitry underneath the display. One or more conductive bridges may pass through holes in the thin-film transistor layer and may have one end that couples to the display circuitry and a second end that couples to a printed circuit underneath the display. These conductive bridges may be formed from wire bonding. Wire bond connections may be encapsulated with potting material to improve the reliability of the wire bond and increase the resiliency of the display. Display signal lines may be routed through holes in a thin-film transistor layer to run along a backside of the display thereby reducing the need for space in the border region for display circuitry.
