Title:
BEAM-SCANNING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/116726
Kind Code:
A1
Abstract:
A scanning image display device comprises: a light source unit for emitting a laser beam; a scanning mirror for two-dimensionally scanning the laser beam in a first direction and a second direction intersecting the first direction; and a control unit for controlling the driving of the scanning mirror. The control unit drives the scanning mirror so that the scanning frequency in the first direction becomes higher than the scanning frequency in the second direction, and changes the scanning amplitude in the first direction by changing the scanning frequency in the first direction in synchronization with the cycle of the scanning frequency in the second direction.
