Document Type and Number:
Japanese Patent JP7091226
Kind Code:
B2
Abstract:
A projector includes a light source module and an optical engine. The light source module provides an illumination beam. The optical engine includes a light valve, a projection lens, and a pixel offset device. The light valve has an active surface, and the active surface converts the illumination beam into an image beam and reflects the image beam. The projection lens projects the image beam from the projector. The pixel offset device is located between the light valve and the projection lens and includes a frame and a transparent panel, the transparent panel is disposed in the frame and includes a transparent surface, the transparent panel is disposed on the transmission path of the illumination beam and the transmission path of the image beam, the frame is configured to drive the transparent panel to vibrate, and the transparent surface is tilted with respect to the active surface.
