Abstract
A lens module includes a lens assembly, an actuator, an encoder, and a controller. The actuator is connected to the lens assembly. The encoder is connected to the actuator and linked with the actuator. The encoder includes a first portion and a second portion. The first portion includes multiple areas, and each of the areas includes at least one conductor. The second portion includes multiple conductive contacts. When the actuator drives the encoder to move, the second portion moves relative to the first portion, and the encoder outputs a voltage signal according to whether the conductive contacts are in contact with the at least one conductor in the areas. The controller is electrically connected to the encoder and the actuator. The controller determines a state of the encoder according to the voltage signal. A projection device and a method for adjusting the lens module are also disclosed.
