Abstract

A display module includes a touch device, a cover lens, a decoration layer, at least one optical module, and a display panel. The touch device is arranged at a lower side of the cover lens for generating a touch signal. The decoration layer is arranged under the cover lens, and has a first hole and at least one second hole, wherein the touch device corresponds to the first hole, and the first hole is larger than the at least one second hole. The at least one optical module is arranged under the cover lens and corresponding to the at least one second hole, for generating an image signal. The display panel is arranged under the decoration layer and the touch device for executing a corresponding operation according to the touch signal or the image signal.
