Abstract: A display device is disposed within a casing of an electronic device. The display device includes a display part, at least one light source, a projection part and an imaging structure. The display part is disposed on the casing and exposed outside. The at least one light source is disposed within the casing, and emits at least one light beam. The projection part is arranged between the at least one light source and the display part, and has an image region. After the at least one light beam passes through the projection part, a projection pattern corresponding to the image region is generated. The imaging structure is disposed on the display part. The imaging structure receives the projection pattern, so that the projection pattern is shown on the display part.

Abstract: The present invention provides a mouse shell with cooling touch, which includes a plastic material and a thermally conductive material, and the thermally conductive material is selected from the group consisting of thermally conductive powders, a thermally conductive object and a combination thereof. The thermally conductive powders are dispersed in the plastic material. The thermally conductive object is covered by the plastic material, or the thermally conductive object is attached beneath the plastic material. The thermally conductive powders are selected from the group consisting of metal powders, alloy powders, ceramic powders and combinations thereof. The thermally conductive object is selected from a metal object, an alloy object, a ceramic object and combinations thereof.
