    摘要: The present invention relates to a display apparatus comprising a light emitting element supplying light, and a switch to switch on and off power, which is supplied to the light emitting element. A comparing unit compares a predetermined first reference voltage and an output voltage which is proportional to a current applied to the light emitting element. A controller compares a comparison voltage output, which is a comparison result of the comparing unit and a predetermined second reference voltage, in order to control the switch to be switched on and off. Accordingly, the present invention provides a display apparatus and control method which precisely controls a size of a current applied to a light emitting element.

    摘要: A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelength. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.
