Abstract

An electronic device comprising: an array substrate having a first electrode and a second electrode; a first connecting member arranged on the first electrode; a first LED chip mounted on the first connecting member; a second connecting member arranged on the second electrode and being thicker than the first connecting member; and a second LED chip mounted on the second connecting member. A distance from a reference surface of the array substrate to a top surface of the second connecting member is larger than a distance from the reference surface to a top surface of the first connecting member.

Claims (31)

1. An electronic device comprising:

an array substrate having a first electrode and a second electrode;

a first connecting member arranged on the first electrode;

a first LED chip mounted on the first connecting member;

a second connecting member arranged on the second electrode and being thicker than the first connecting member; and
