Embodiment Construction

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specify...

Abstract

The invention provides an extrusion type liquid lens and a lens module. According to the extrusion type liquid lens provided by the embodiment of the invention, the plurality of first light-transmitting rings are arranged, each first light-transmitting ring is provided with the first light-transmitting coil which is driven by the magnetic field to move under the power-on condition, and meanwhile,the first transparent elastic sheet is arranged to support the first light-transmitting coil. When the extrusion type liquid lens is placed in a set magnetic field, the first light-transmitting coilsare powered on respectively, so that induced magnetic fields are generated on the first light-transmitting coils, and the induced magnetic fields and the set magnetic field act to drive the corresponding first light-transmitting coils to move so as to drive the first light-transmitting film plates to move at corresponding positions; and by controlling the magnitude and direction of the current ineach first light-transmitting coil, the moving position of the corresponding first light-transmitting 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 the small-sized lens module, it is 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. Squeeze-type liquid lenses are generally filled with light-transmitting liquid in the light-transmitting cavity, and one end of the cavity is a flexible light-transmitting film, and an extrusion ring is set to squeeze the flexible light-transmitting film through the extrusion ring. The shape of the flexible light-transmitting film in the pressure ring to change the curvature of the liquid light transmission. However, this kind of liquid lens can generally only f...
