Title:
スペックルを減らすためのスクリーン振動
Document Type and Number:
Japanese Patent JP6579341
Kind Code:
B2
Abstract:
The present disclosure provides discussion of screen vibration to reduce speckle in display applications and/or projection screens. Electrical transducers or reactors may be used with a screen to reduce or remove speckle in projection screens and/or display applications. Electrical transducers may not be directly mounted to a screen, thus eliminating many mechanical failure modes associated with a vibrating transducer as well as resulting in a much quieter operation. By design, the reactors or transducers may actually contact the screen, and can take up less than one square inch of screen surface each, than previous designs, which may be outside of the active viewing area and within 12 inches of the screen border, preferably less than approximately 1 inch from screen edge. The reactors are magnets, though any ferrous material can be made to work with certain operating conditions.
