摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.

摘要： An interlace-type PDP is driven by an improved driving method so as to achieve a greater operating margin, higher resolution, and higher brightness. The interlace-type PDP is driven using odd and even frames in such a manner that the cells are grouped into cell groups such that each cell group includes two or three cells which are adjacent in a direction crossing the electrode pairs, and the cells are driven in units of cell groups. The grouping of cells is performed differently for even and odd frames such that, in one type of frame, locations of two or three cells grouped into each group are shifted by one cell, in the direction crossing the electrode pairs, from the locations of cells grouped together in the other type of frame.
