Touch device with fingerprint recognition

Abstract

The invention provides a touch device with fingerprint recognition. The touch device with fingerprint recognition comprises a touch device and a fingerprint recognition unit; the touch device includes a touch area and a non-touch area, wherein the non-touch area is adjacent to the touch area and arranged at the periphery of the touch area; and the fingerprint recognition unit is arranged at the non-touch area. According to the touch device with fingerprint recognition provided by the invention, by integrating the fingerprint recognition unit and the touch device as a whole, the disadvantage of the prior art that a slot or a hole needs to be additionally opened on the touch device to break the structural strength of the touch device can be improved and the manufacturing cost can be reduced.

Description

technical field [0001] A touch device with fingerprint identification, especially a touch device with fingerprint identification, which is directly integrated and formed on the touch device, thereby improving the accuracy of fingerprint identification and reducing manufacturing costs. Background technique [0002] With the vigorous development of multimedia technology, more and more intelligent portable electronic devices such as mobile phones, personal digital assistants (Personal Digital Assistant, PDA), digital cameras, personal notebook computers or tablets or wearable devices have become necessary in people's lives. Tool of. However, these portable electronic devices have strong personal characteristics. Therefore, once these portable electronic devices are stolen or lost, the information stored in them, such as phonebooks, photos, data, etc., may be used by others, causing unnecessary losses. [0003] Therefore, such products need to be equipped with certain identi...

Problems solved by technology

[0005] However, in the prior art, each sensing circuit and metal wiring or chip must first be arranged on a substrate made of a silicon wafer, integrated into a fingerprint identification unit and then used in combination with a touch panel or other devices. The overall thickness of the fingerprint identification unit provided by the technology is also relatively thick, and it is easy to affect the accuracy of fingerprint identification due to the thickness, and it cannot be integrated with a thinner device due to thickness considerations.

[0006] At the same time, generally speaking, when a finger touches the sensing area of ​​the chip, the overall thickness of the chip packaging module is relatively high due to the multi-layer film covering the outside of the chip, and the sensitivity of the chip packaging module is low.

[0007] In addition, the existing sliding fingerprint identification system is directional, and the identification time is too long and must be set independently, which is not good in terms of structural integration or usability
