Abstract
The utility model provides a camera module comprising a zoom lens. Electricity is supplied to the zoom lens and voltage vibration is controlled. Therefore, the slope of liquid crystal molecules in a liquid crystal lens in the zoom lens is changed in order to simulate different optical lenses. Thus, the relative distance of a light sensitive chip of the camera module is changed so as to achieve a zooming effect. Preventing a coil motor from installing, the camera module may achieve the zooming effect with the zoom lens. Moreover, the zoom lens eliminates problems of aging liability, shortened service lives, and increased failure rate of components caused by vibration arising from the physical motion of the components in a zooming process, thereby enhancing the reliability of the camera module. Compared with multiple mechanical assemblies of the coil motor, the zoom lens has characteristics of simple zooming structure, easy assembly, and low production cost. In addition, the liquid crystal lens of the zooming lens has low thickness and does not occupy space, complying with a light and thin development tendency of the camera module and enlarging an application range.
