Abstract: Light emitting devices comprise a substrate having a surface and a side surface; a semiconductor structure on the surface of the substrate, the semiconductor structure having a first surface, a second surface and a side surface, wherein the second surface is opposite the first surface, wherein the first surface, relative to the second surface, is proximate to the substrate, and wherein the semiconductor structure comprises a first-type layer, a light emitting layer and a second-type layer; a first and a second electrodes; and a wavelength converting element arranged on the side surface of the semiconductor structure, wherein the wavelength converting element has an open space, and wherein the open space is a portion not covered by the wavelength converting element.

Abstract: A menu input method for a mobile terminal including displaying a menu having a plurality of items on a display of the mobile terminal, displaying a cursor used to select one of the plurality of items at a first position on the display, capturing images of a pointer object moving in front of an image capturing device included with the mobile terminal, and converting the captured images into coordinate values of the cursor and moving the cursor to a second position on the display based on the converted coordinate values
