Abstract:
Provided is a display device, which includes a light source, a light guide plate, a light conversion member, and a display panel. Light is incident to the light guide plate from the light source. The light conversion member is between the light source and the light guide plate. The display panel is on the light guide plate. The light guide plate includes a central region corresponding to an available display region of the display panel for displaying an image, an outer region around the central region, and a total reflection surface inclined from an optical axis of the light source, and disposed in the outer region.
Abstract:
A lens moving device is provided. The lens moving device includes: a bobbin; a first driving unit coupled to the bobbin; a second driving unit configured to move the first driving unit through an electromagnetic interaction with the first driving unit; a sensing magnet disposed on one side of the bobbin; a location detection sensor configured to sense a location of the sensing magnet; and a correction magnet disposed on an opposite side of the bobbin. According to the present disclosure, static tilt and dynamic tilt of the bobbin, to which a lens module is to be coupled, may be enhanced by a sensing magnet and a correction magnet which establish magnetic force equilibrium with each other.
