Claim of US Patent No. 9,516,743

1. A display, comprising:
a display substrate having an active area, an inactive area, and a locally thinned region, wherein the locally thinned region
is located in the inactive area;

an array of display pixels on the display substrate in the active area;
display circuitry including gate driver circuitry on the display substrate in the inactive area, wherein the gate driver circuitry
overlaps the locally thinned region of the display substrate, wherein the display pixels lie in a plane, and wherein the locally
thinned region of the display substrate curves out of the plane such that the inactive area is at least partially hidden from
view by a user; and

an encapsulation layer formed over the gate driver circuitry such that a neutral stress plane intersects with and spans laterally
across the entire width of the gate driver circuitry over the locally thinned region of the display substrate.
