Displays with Shared Flexible Substrates
First Claim
1. An electronic device, comprising:
- a display having an array of display pixels;
a polymer film having a first plurality of metal traces;
a flexible printed circuit having a second plurality of metal traces, wherein the display, the polymer film, and the flexible printed circuit share a flexible polymer substrate layer; and
a transition region interposed between the polymer film and the flexible printed circuit, wherein the transition region is thicker than the flexible printed circuit.

Abstract
An electronic device may be provided with a display such as an organic light-emitting diode display. The display may include an array of display pixels formed on a polymer substrate layer. The polymer substrate layer may include an contiguous layer of polyimide that forms a substrate layer in additional structures such as a polymer film and a flexible printed circuit. A first transition region may be interposed between the display and the polymer film, and a second transition region may be interposed between the polymer film and the flexible printed circuit. Metal traces may be formed on the polymer film and on the flexible printed circuit. A display driver integrated circuit may be mounted to the traces on the polymer film. The polymer film may form a U-shaped bend. The flexible printed circuit may be coupled to a printed circuit board in the device using hot bar solder connections.
