Abstract

The invention provides an extrusion type liquid lens and a lens module. The invention provides an extrusion type liquid lens. A plurality of first transparent rings are arranged; each first transparent ring is provided with a first transparent coil which is driven by a magnetic field to move when being electrified; when the extrusion type liquid lens is placed in a set magnetic field, all the first transparent coils are powered on, an induced magnetic field is generated on each first transparent coil, and under the action of the induced magnetic fields and the set magnetic field, the corresponding first transparent coils are driven to move so as to drive the corresponding positions of the first light-transmitting film plates to move; and by controlling the magnitude and the direction of the current in each first transparent coil, the moving position of the corresponding first transparent ring can be controlled, so that the shape of the first light-transmitting film plate is adjusted, and a spherical lens or an aspheric lens can be formed.

Description

technical field [0001] The present application belongs to the field of liquid lenses, and more specifically relates to an extruded liquid lens and a lens module. Background technique [0002] Lens modules in mobile terminals such as smart phones are generally small in size. In order to adapt to the zooming of small-sized lens modules, it is currently proposed to use a liquid lens as a lens in the lens module, and to change the focal length of the lens module by changing the curvature of the liquid lens to achieve zooming. The current extruded liquid lens generally fills the light-transmitting cavity with a light-transmitting liquid, and makes one end of the cavity a flexible light-transmitting film, and sets an extrusion ring to squeeze the flexible light-transmitting film through the extrusion ring. Squeeze the shape of the flexible light-transmitting film in the ring to change the curvature of the liquid light-transmitting. However, this kind of liquid lens can generally...
