Abstract: A liquid crystal display device includes a liquid crystal panel, a light-guiding plate, a light source, and an optical sensor. The light source is attached to an end face of a bottom of the light-guiding plate so as to emit light, which is guided into the light-guiding plate so as to illuminate the liquid crystal panel. The optical sensor having a photo-acceptance part is attached to a rear face of a chassis so as to partially detect light. A panel opening is formed by attaching a gobo to an opening formed in the chassis at a side end of the light-guiding plate, thus regulating the range of light received with the photo-acceptance part of the optical sensor. Thus, it is possible to precisely detect the intensity of light by use of the panel opening which eliminates high-intensity light reflected by an edge-reflection sheet of the light-guiding plate.

Abstract: A display device includes: a first video signal input unit that receives a first video signal; a second video signal input unit that receives a second video signal; a video signal rotating unit that converts the first video signal so that an image based on the first video signal rotates, to obtain a converted video signal; a video combining unit that combines the second video signal with the first converted image signal to obtain a combined video image signal; and a display unit that displays a combined video image based on the combined image signal.

Abstract: There is provided a disk drive including a base chassis, a first optical pickup mechanism including a disk rotation drive disposed on the base chassis, first optical pickup unit to write and/or read data to and/or from a first optical disk and a first pickup moving mechanism to move the first optical pickup unit radially of the first optical disk, a second optical pickup mechanism disposed opposite to the first optical pickup mechanism and including a second optical pickup unit to write and/or read data to and/or from a second optical disk and a second pickup moving mechanism to move the second optical pickup unit radially of the second optical disk, and a controlling means for detecting the movement of one of the optical pickup units and moving the other optical pickup unit to make weight balancing of the base chassis. Thus, the base chassis weight is balanced while one of the two optical pickup units is being moved.
