Embodiment Construction

[0030] It can be seen from the background technology that the process of forming a fingerprint imaging module with a smaller thickness is more difficult in the prior art. Combining with the structure of a fingerprint imaging module, the reasons for its large thickness and difficulty in reducing the thickness are analyzed.

[0031] The optical fingerprint imaging module mainly includes: protective cover, optical sensor, integrated chip (IC), flexible circuit board (FPC) and electronic devices on the flexible circuit board (including light source LED), light guide plate, upper protective shell and Lower protective shell and other main components. Among them, the optical sensor is made on a glass substrate using semiconductor technology such as amorphous silicon thin film transistor (a-Si TFT), low temperature polysilicon thin film transistor (LTPS TFT) or oxide semiconductor thin film transistor (OS TFT); after cutting , dispensing, bonding and other processes to achieve packag...

Abstract

A method for forming an image sensor, and a fingerprint imaging module are disclosed. The method includes the steps of providing a substrate having a pixel array; providing a coiled protective layer;attaching the coiled protective layer to the surface of the pixel array; cutting the coiled protective layer to obtain the image sensor. In the technical scheme of the invention, the method of formingthe image sensor by attaching the coiled protective layer can effectively reduce limitation on the process of forming the protective layer, reduce the process difficulty of processing, transporting and assembling the protective layer, and is favorable for improving the yield of forming the image sensor and favorable for cost control.

Description

technical field [0001] The invention relates to the field of fingerprint imaging, in particular to a method for forming an image sensor and a fingerprint imaging module. Background technique [0002] The fingerprint identification technology collects the fingerprint image of the human body through the fingerprint imaging module, and then compares it with the existing fingerprint imaging information in the fingerprint identification system to realize identity identification. Due to the convenience of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as: public security bureaus, customs and other security inspection fields, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] The imaging methods of the imaging module used in the fingerprint identification technology include optical, capacitive, ultrasonic and other technologies. One of them...
