Abstract
A projection lens module and a projector are provided. The projector includes an optical engine and a projection lens module. The optical engine includes a casing, a light source, a light valve, and a prism, where the light source, the light valve, and the prism are disposed in the casing. The light source emits an illumination beam to the light valve. The light valve modulates the illumination beam to generate an image beam and projects the image beam to the projection lens module. The prism is disposed on an optical path of the image beam. The projection lens module is connected to the casing of the optical engine and is configured to project the image beam. The projection lens module includes a projection lens and a smooth picture actuator, where the smooth picture actuator is fixed to the projection lens and is located outside the optical engine.
