Abstract
There is provided a flexible display having a plurality of innovations configured to allow bending of a portion or portions to reduce apparent border size and/or utilize the side surface of an assembled flexible display.
Claims21
A display apparatus, comprising:
- a base layer having a bend allowance section between a first portion and a second portion of the display apparatus;
- a buffer layer on the base layer, and the bend allowance section has an etched buffer layer part so as to facilitate easier bending of the bend allowance section;
- an organic light-emitting diode (OLED) element on the buffer layer;
- a wire trace having a strain-reducing trace design across the bend allowance section between the first portion and the second portion;
- and
- an organic-coating layer on the wire trace and over the bend allowance section.

A display apparatus, comprising:
- a base layer having a bend allowance section between a first portion and a second portion of the display apparatus, the first portion having an active area and a first routing area, and the second portion having a second routing area and a pad area;
- a buffer layer on the base layer, and the bend allowance section has an etched buffer layer part so as to facilitate easier bending of the bend allowance section;
- an organic light-emitting diode (OLED) element on the buffer layer;
- a plurality of wire traces having a strain-reducing trace design across the bend allowance section between the first routing area and the second routing area, and the plurality of wire traces merged to a reinforced portion in an abridged area;
- and
- an organic-coating layer on the plurality of wire traces and over the bend allowance section.

- an organic light-emitting diode (OLED) element on the buffer layer;
- a plurality of wire traces having a strain-reducing trace design across the bend allowance section between the first routing area and the second routing area, and the plurality of wire traces merged to a reinforced portion in an abridged area to make the plurality of wire traces harder to hold out against bending stress when the bend allowance section being bent;
- and
- an organic-coating layer on the wire trace and over the bend allowance section of the base layer to protect against moistures and other foreign materials.
