Abstract

A touch-control type keyboard includes a transparent cover board and a touch-control module laminated with the transparent cover board. The transparent cover board includes an outer surface and an inner surface opposite to the outer surface. The outer surface of the transparent cover board includes a tactual zone and a relative anti-tactual zone. The tactual zone includes micro structures on the outer surface.

Claims
