Abstract

A touch keyboard includes a touch panel, a light guide plate, a keyboard layer, and a controller. The controller is connected to the touch panel.

The keyboard layer is sandwiched between the touch panel and the light guide plate. The keyboard layer includes a film and a plurality of keyboard signs printed on the film, and the positions of the keyboard signs are recorded in the controller.
