发明名称 IMAGE DISPLAY APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide an image display apparatus generating a speckle noise in a given image area effectively by using a single laser light source. SOLUTION: The laser light source 1 outputs a laser. A condenser lens 80 condenses the laser outputted from the laser light source 1, and outputs it to an optical fiber 8. The laser that propagates through the optical fiber 8 enters a light guide panel 2. The light guide panel 2 converts the inputted laser into a planar illumination light. The planar illumination light passes through a light passing control section 4 and illuminates a liquid crystal panel 7, which is a spatial modulation element that converts light into an image. The light passing control section 4 controls a scatter pattern during the passing of the laser individually in each predefined image area, by a control circuit 81. Consequently, an image area 5 in which a speckle noise is reduced and an image area 6 in which the speckle noise is generated, are formed on a liquid crystal panel 7. COPYRIGHT: (C)2009,JPO&INPIT
