Abstract

A touch-type transparent keyboard includes a transparent substrate, a keyboard layer, a first insulation layer, a shield layer, a second insulation layer, a position detection layer, a transparent protective layer, and a control module. The keyboard layer and the control module are located on the transparent substrate. The first insulation layer is attached to the keyboard layer. The shield layer is located between the first insulation layer and the second insulation layer. The position detection layer is located between the second insulation layer and the protective layer. The keyboard layer, the shield layer and the position detection layer are electronically connected to the control module.

Claims
