Problems solved by technology

The size of a wafer-level lens module is usually only 1 / 3 or 1 / 4 of the size of a traditional mobile phone lens. Therefore, it is difficult for a voice coil motor (VCM) suitable for a traditional mobile phone lens to compete with a wafer-level lens module. group matches

Embodiment Construction

[0014] like Figure 1 to Figure 3 As shown, a camera module 100 provided by an embodiment of the present invention includes a frame 10 , a wafer-level lens 20 , an image sensor 30 , a liquid crystal lens 40 and a shading film 50 .

[0015] The frame 10 is made of plastic molding. In this embodiment, the frame 10 can be made of liquid crystal polymer (liquid crystal polymer, LCP) and is black. In other embodiments, the frame 10 is also Other colors are available. The frame 10 is a hollow cuboid and includes a pair of first side walls 101, a pair of second side walls 102 vertically connected to the first side walls 101, a first end surface 103 and a The end surface 103 is opposite to the second end surface 104 . The first end surface 103 and the second end surface 104 are two opposite end surfaces of the pair of first side walls 101 and the pair of second side walls 102 . Both the first end surface 103 and the second end surface 104 are substantially square. The frame 10 def...

Abstract

The invention provides a camera module including a frame, a wafer-level lens, an image sensor and a liquid crystal lens. The wafer-level lens, the image sensor and the liquid crystal lens are all accommodated in the frame. The wafer-level lens module includes a lens barrel and at least one lens accommodated in the lens barrel. The lens barrel includes a top surface and a bottom surface opposite to the top surface. The liquid crystal lens is arranged on the top surface and is opposite to the at least one lens. The image sensor is disposed on the bottom surface and is opposite to the at least one lens. The light passes through the liquid crystal lens and the at least one lens in sequence and then projects to the image sensor. The liquid crystal lens is a transmissive liquid crystal panel. In this way, the focusing function can be realized through the liquid crystal lens; since the liquid crystal lens and the wafer-level lens are both produced through a semiconductor manufacturing process and are accommodated in the frame, the size of the liquid crystal lens can be matched with that of the wafer-level lens. The dimensions of the lenses match.

Description

technical field [0001] The invention relates to a camera module. Background technique [0002] With the development trend of miniaturization and low price of mobile phone camera modules, the emergence of wafer level camera (wafer level camera, WLC) technology has attracted much attention. Wafer-level camera technology raises the manufacturing of optical components to the wafer level. Its lenses use reflowable lens materials, and use semiconductor technology to manufacture thousands of lenses on a wafer, and use wafer-level packaging technology to After these lenses are arranged on the wafer and combined with the image sensor, they are diced into independent wafer level modules (WLM). The size of a wafer-level lens module is usually only 1 / 3 or 1 / 4 of the size of a traditional mobile phone lens. Therefore, it is difficult for a voice coil motor (VCM) suitable for a traditional mobile phone lens to compete with a wafer-level lens module. group matches. Contents of the inve...
