摘要： In a three dimensional video display device (1), an LED unit (10) rotates in the direction of the arrow (24) along top and bottom edges of a display section (28). The LED unit (10) has a left-eye LED array (6) and a right-eye LED array (8), each including plural LEDs (4) aligned in a column. The left-eye LED array (6) displays a left-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the left-eye image. The right-eye LED array 8 displays a right-eye image through an afterimage effect produced by displaying, while rotating, columns of pixel groups constituting the right-eye image. Light from the left-eye image enters the left eye of a viewer, whereas light from the right-eye image enters the right eye. The viewer recognizes a three dimensional image in a range of 360° around the viewer based on binocular parallax.

摘要： A light diffusing member includes a base material having a light transmitting property; a plurality of light blocking sections that are formed in a scattered manner at one surface of the base material; and a light transmissive material layer that is formed at the one surface of the base material. A thickness of the light transmissive material layer is larger than a thickness of each light blocking section. The light transmissive material layer has hollow portions in regions where the light blocking sections are formed. Each hollow portion has a shape in which a cross-section area when each hollow portion is cut at a plane that is parallel to the one surface of the base material is large on a side of the corresponding light blocking section and becomes gradually smaller with increasing distance from the corresponding light blocking section. A portion of the light transmissive material layer other than where the hollow portions are formed is a light transmitting section.

摘要： To solve problematic trade-off between a bandwidth and a in-band deviation in an optical signal receiving circuit of a gigabit order that is required to have a wide dynamic range, the optical signal receiving circuit has a current-voltage conversion circuit that receives as an input a current signal outputted from a photoelectric conversion circuit for receiving and converting an optical signal into a current signal and converts it into a voltage signal, and realizes the wide dynamic range by providing the current-voltage conversion circuit with an AGC function and a phase compensation function by MOS transistors and a capacitance. Further, by providing the current-voltage conversion circuit with a second phase compensation function by a MOS transistor and a capacitance, it is made possible for the optical signal receiving circuit to reduce the in-band deviation at the time of minimum gain while securing the bandwidth at the time of maximum gain.
