Display and method of manufacturing the same

Abstract

A display includes a cover plate, an electromagnetic induction layer, a display unit disposed between the cover plate and the electromagnetic induction layer, first, second, and third adhesive layers, first and second shielding layers, and a housing. The electromagnetic induction layer includes a flexible substrate and a sensing electrode layer. The flexible substrate has a first surface facing the display unit and an opposite second surface. The first adhesive layer is disposed on the first surface and connects to the display unit, and its thickness is approximately 2 to approximately 12 times the thickness of the sensing electrode layer, such that the sensing electrode layer is embedded in the first adhesive layer. The second adhesive layer is disposed on the second surface and has a thickness less than that of the first adhesive layer. The first shielding layer connects to the second adhesive layer and completely covers the flexible substrate. The third adhesive layer connects the first shielding layer and the second shielding layer, and its thickness is less than or equal to that of the first adhesive layer. The housing and the cover plate form an external accommodating space.

Claims
