Optical module and electronic equipment

Abstract

The invention provides an optical module and electronic equipment, relates to the technical field of optical imaging, and can improve the imaging quality when the optical module is applied to the electronic equipment through the arrangement of each optical element in the optical module. The optical module comprises a lens component and an image sensor arranged on the imaging side of the lens component, the imaging surface of the lens component on a to-be-recognized object is an arc-shaped image surface, the light-sensitive surface of the image sensor is arranged between the lowest point of the arc-shaped image surface and the highest point of the arc-shaped image surface, the optical module is used for fingerprint recognition, and the to-be-recognized object is a fingerprint. The optical module can balance the distance from the light-sensitive surface to the central area of the imaging surface and the distance from the light-sensitive surface to the edge area of the imaging surface, and balance the definition of the image received by the light-sensitive surface of the image sensor, so that the definition of the image with biological information received by the image sensor is relatively balanced; therefore, the biological information can be extracted and analyzed from the clear image for recognition, and the recognition accuracy of the optical module on the to-be-recognized object is improved.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical module and electronic equipment. Background technique [0002] With the development of portable terminal equipment represented by mobile phones, the application of biometric technology is becoming more and more extensive and in-depth. Taking electronic devices as an example, fingerprint recognition, fingerprint verification, face recognition, etc., have been more and more used in the screen wake-up of display devices and the identity authentication steps of various programs, improving the security and usage of display devices flexibility. [0003] In the prior art, an optical module is installed in an electronic device, such as a fingerprint module for fingerprint identification, or a lens module for taking pictures of faces or capturing video images, etc. The location of the recognition is different, the recognition or collection area can be set in...

Problems solved by technology

[0004] An optical module usually includes multiple optical components that need to be set and fixed in relation to each other according to specific focal length and other parameters. After the optical components of the optical module are assembled and fixed inside the electronic device, the structure of the optical module will It is difficult to change and adjust, which will affect the imaging quality of the image
