Problems solved by technology

[0006] With the rise of mobile Internet and e-commerce, the security issues of handheld terminals (mainly mobile phones) have gradually emerged. The installation of fingerprint recognition systems for them has become an urgent need for various manufacturers. The method currently adopted is to install independent fingerprint recognition systems. Module, place the fingerprint identification area under the front screen of the mobile phone or on the back shell of the mobile phone. This method has problems such as poor user experience and limited mobile phone design.

Embodiment 1

[0028] see figure 2 , is a structural schematic diagram of a fingerprint identification system combined with touch screen technology provided by the present invention; the fingerprint identification sensor 21 for sensing fingerprints is a conductive pattern sensor; specifically, the conductive pattern sensor can be selected from ITO film Sensor, the protective plate 20 on the surface of the fingerprint recognition sensor 21, the protective plate 20 can be transparent and non-transparent materials; the fingerprint recognition sensor 21 is provided with a substrate 22 and a fingerprint recognition chip below the fingerprint recognition sensor 21, the substrate 22 and the fingerprint The identification chip can be integrated into a one-piece structure. In addition, the fingerprint recognition sensor 21 is connected with a first flexible circuit board 23 , and the first flexible circuit board 23 is used to communicate with the main board of the device.

[0029] see Figure 4 an...

Embodiment 2

[0031] see image 3 , for when the fingerprint identification sensor 21 is directly integrated on the protective plate 20, the substrate 22 can be directly eliminated, and the protective plate 20 can also act as the substrate of the fingerprint identification sensor at this time.

[0032] Comparison figure 1 , 2 And 3, the three structures correspond one by one, the fingerprint recognition sensor 21 can be combined with the nano-indium tin metal oxide ITO sensor 10; the protective plate 20 can be combined with the cover plate (Cover Lens) 11; the first flexible circuit board 23 can be combined with the The second flexible circuit board 12 is combined; in summary, the fingerprint identification system and the touch screen technology can be integrated.

[0033] From the above description, it can be seen that a fingerprint identification system combined with touch screen technology has at least the following advantages:

[0034] (1) It can improve user experience. The existin...

Abstract

The invention provides a fingerprint identification system combined with a touch screen technology. The fingerprint identification system comprises a fingerprint identification sensor, a protective plate, a substrate, a fingerprint identification chip and a flexible circuit board, wherein the fingerprint identification sensor is used for sensing fingerprints; the protective plate is arranged on the fingerprint identification sensor and is in direct contact with a human hand; the substrate is arranged under the fingerprint identification sensor; the fingerprint identification chip is used for processing the sensed data; the fingerprint identification sensor can be directly integrated with the protective plate on the fingerprint identification sensor, and can be integrated with the substrate and the fingerprint identification chip under the fingerprint identification sensor; the flexible circuit board is connected with the fingerprint identification sensor, is used for connecting an equipment mainboard, and is combined with a circuit board of the touch screen. The fingerprint identification system combined with the touch screen technology provided by the invention can enhance user experience, simplify the process technology and reduce the difficulty of product appearance design.

Description

technical field [0001] The invention relates to the field of capacitive touch screens, in particular to a fingerprint identification system combined with touch screen technology. Background technique [0002] Fingerprint identification technology is currently the most mature and cheap biometric identification technology. At present, the fingerprint recognition technology is the most widely used. We can not only see the fingerprint recognition technology in the access control and attendance system, but also have more fingerprint recognition applications in the market: such as laptops, mobile phones, cars, bank payments, etc. Fingerprint recognition technology can be applied. [0003] In computer applications, including the protection of many very confidential files, most of them use the "user ID + password" method for user identity authentication and access control. However, if the password is forgotten or stolen by others, the security of the computer system and files will...
