DISPLAY DEVICE

摘要

A display device includes: a light source unit (4) for emitting coherent light and projecting a video; and an image reception unit (1) consisting of two or more screens for projecting the coherent light. Air flow is supplied to the front surface or rear surface of the image reception unit (1) so as to vibrate at least one of the screens constituting the image reception unit (1). Furthermore, the image reception unit (1) includes the function of a loudspeaker. Thus, when the coherent light is used as the display light source, it is possible to suppress the light intensity irregularities called speckle noise which is generated by interference of the laser light reflected from the light reception unit.
