Problems solved by technology

[0003] However, the materials of the lens holder and the lens barrel of the existing lens module are mostly plastics such as PC / ABS (polypropylene / acrylonitrile-butadiene-styrene) engineering plastics, polytetrafluoroethylene, etc., which usually do not have good Excellent anti-electromagnetic wave interference ability, the image sensor components are easily affected by external electromagnetic wave interference and generate noise, resulting in the inability to obtain a clear image, resulting in poor image quality

Embodiment Construction

[0010] The lens module 10 provided by the embodiment of the technical solution will be further described below with reference to the accompanying drawings.

[0011] Please also refer to figure 1 and figure 2 , the lens module 10 provided by the embodiment includes a lens barrel 110 , a filter 120 , a spacer ring 130 , a lens group 140 and a lens holder 150 .

[0012] The lens barrel 110 is a cylinder for accommodating the filter 120 , the spacer ring 130 and the lens group 140 . The lens barrel 110 includes a first end portion 111 and an opposite second end portion 112 . The first end portion 111 is provided with a light entrance hole 113 through which light can enter the lens module 10 and pass through the filter 120 and the lens module 140 sequentially. The outer wall of the second end portion 112 can be provided with threads for matching with the threads provided on the lens mount 150 so that the lens barrel 110 can be fixed on the lens mount 150 . Of course, the lens ...

Abstract

The present invention relates to a lens module which comprises a lens base and a barrel fixed on the lens base. The barrel is accommodated with a color filter, a spacing ring and a lens array. The external surface of the lens base is provided with an electromagnetic shielding layer. The electromagnetic shielding layer is a carbon nano-tube / polymer composite material which comprises a polymeric substrate and carbon nano-tube dispersed in the polymeric substrate. The lens array can effectively shield the interference of the external electromagnetic wave to the image sensor thereby increasing the imaging quality.

Description

technical field [0001] The invention relates to a lens module, in particular to a lens module with good anti-electromagnetic wave interference capability. Background technique [0002] The camera function has become one of the indispensable main functions of various portable electronic products such as mobile phones and personal digital assistants (PDAs). A camera module usually includes at least one lens module, and an image sensor element disposed opposite to the lens module. The lens module usually includes a lens mount, a lens barrel disposed on the lens mount, and optical components such as a lens group, a spacer ring, and an optical filter sequentially fixed in the lens barrel along the optical axis direction. The image sensor element is usually packaged in the lens holder, or directly packaged in the bottom of the lens barrel, and is used for imaging in cooperation with the lens module. [0003] However, the materials of the lens holder and the lens barrel of the ex...
