Abstract: An electronic device includes a light emitting layer, a light conversion layer and an adjustable structure. The light emitting layer has a plurality of light emitting units for emitting light. The light conversion layer converts the wavelength of the light emitted by at least one light emitting unit to provide converted light. The adjustable structure is controlled to adjust a light penetrating area to correspond to the affected part to be treated, wherein at least one of the light and the converted light passes through the light penetrating area to irradiate the affected part.

Abstract: A touch display device fixed on a vehicle and including a display portion is provided. The display portion includes an information display area, a first interface and a second interface. The first interface and the second interface can be displayed at two sides of the display portion simultaneously. The first interface is near a driver seat and the second interface is near a non-driver seat. Moreover, a display method applied to a touch display device for a vehicle is also provided herein.

Abstract: A stereoscopic user interface displayed on a display module of an electronic device is disclosed. The stereoscopic user interface includes a polyhedron which has a plurality of regions. Each of the regions displays different information. When one of the regions receives a first command, the region moves to a first position from the polyhedron. The first position is connected to the polyhedron or apart from the polyhedron. A displaying method of a stereoscopic user interface is also disclosed.
