Fingerprint recognition device, touch screen display and intelligent equipment for intelligent robot

Abstract

The invention relates to a fingerprint recognition device. The fingerprint recognition device comprises a substrate, a driving circuit and a photoelectric sensor array and cover plates, wherein the driving circuit and the photoelectric sensor array are arranged on the substrate and are used for recognizing fingerprints; and the cover plates are opposite to the substrate, are used for protecting the driving circuit and the photoelectric sensor array and can be protruded upwards so as to drain drips and / or grease. According to the fingerprint recognition device, a touch screen display, intelligent equipment and an intelligent robot, bulges are formed according to different thermal expansion coefficients between two layers of the cover plates, so that slipping of water stain or greasy dirt isfacilitated, the surface cleanness of the fingerprint recognition device is increased, and then the recognition success rate is increased; and furthermore, a plurality of fingerprint recognition devices are integrated into the touch screen display, so that the equipment safety is improved.

Description

technical field [0001] The invention relates to the field of touch screen displays, in particular to a touch screen display and an intelligent device for intelligent robots that can effectively improve fingerprint recognition efficiency. Background technique [0002] With the development of robot technology, robots are used in various fields. Existing robots are divided into two categories, namely industrial robots and special robots. The so-called industrial robot is a multi-joint manipulator or multi-degree-of-freedom robot for the industrial field. Special robots are all kinds of advanced robots that are used in non-manufacturing industries and serve human beings in addition to industrial robots, including: underwater robots, entertainment robots, military robots, agricultural robots, robotized machines, etc. Service robots are often used in service industries such as banks, shopping malls, restaurants, sales departments, hotels, etc. Checkout, entertainment and other w...

Problems solved by technology

[0004] However, the top of the existing fingerprint identification device has a horizontal structure, which is easily disturbed by water or oil stains on the fingers. In the absence of suitable wiping equipment, it is often necessary to swipe multiple times or use multiple fingers to refresh until the water stains or oil stains on the top evaporate. Part of it can be successfully recognized, the recognition success rate is low, and the user experience is poor

In addition, existing fingerprint recognition devices are only located in a small area of ​​the mobile device and are discrete devices that can only detect one fingerprint at a time

When the user's fingerprint is taken maliciously, or when the user is in an unconscious state such as sleep and is forced to press by a third party's finger, a device that can only recognize one fingerprint cannot effectively protect the security of mobile devices
