Description

Intelligent integrated fingerprint identification mobile phone

technical field

The utility model relates to an intelligent integrated fingerprint identification mobile phone.

Background technique

Fingerprint identification technology is a biometric identification technology that reads the fingerprint image through the imaging device, then extracts the characteristic data of the fingerprint with computer identification software, and finally obtains the identification result through a matching identification algorithm to determine the identity of the fingerprint owner. The fingerprint identification module involves processes such as fingerprint image acquisition, fingerprint image processing, feature extraction, data storage, comparison and matching of feature values.

At present, the technology for collecting fingerprint information usually adopts optical fingerprint collection technology and semiconductor fingerprint collection technology. Optical fingerprint collection technology mainly uses the principle of total reflection of light. When a beam of light hits a finger placed on a glass platform, the reflected light of this beam of light is sensed by the image sensor. The properties of the reflected light are consistent with the ridge line of the finger , the depth between the valley lines, and the oil and moisture layers between the glass and the skin. After the light hits the valley line through the glass, it will be totally reflected at the interface between the glass and the air. The contact surface of the glass absorbs or diffusely reflects and is emitted to other places, and then a fingerprint image can be formed on the image sensor to complete the information collection of the fingerprint.

Semiconductor fingerprint sensors are often used to collect fingerprint information on mobile phones. For example, in the mobile phone with fingerprint recognition function disclosed in the Chinese utility model patent with the authorized announcement number CN201985958U, a capacitive fingerprint sensor is installed on the keyboard operation area on the front of the mobile phone body. The fingerprint information is collected by the fingerprint sensor, and the fingerprint information is transmitted to the fingerprint identification module provided inside the mobile phone body for fingerprint identification and judgment, and then subsequent operations are performed. However, most of the semiconductor fingerprint sensors on such mobile phones need to be installed in the keyboard area, which takes up additional space in the keyboard area and makes the mobile phone bulky, which is not conducive to the development of mobile phone miniaturization.

Contents of the invention

The utility model provides an intelligent integrated fingerprint recognition mobile phone which uses optical fingerprint collection technology to collect fingerprints, so as to solve the technical problem that the capacitive fingerprint sensor on the mobile phone occupies the space of the keyboard area in the prior art.

The technical scheme of the intelligent integrated fingerprint identification mobile phone provided by the utility model is: the intelligent integrated fingerprint identification mobile phone includes a mobile phone body, the mobile phone body has a liquid crystal display and a transparent protective screen arranged above the liquid crystal display, and the liquid crystal The display screen is provided with a light-emitting aperture as a light source and used to mark the fingerprint collection area on the transparent protective screen, and a light ring for receiving fingers pressing on the fingerprint collection area is provided at a position corresponding to the fingerprint collection area under the liquid crystal display screen. The image sensor of the fingerprint image is also provided with an image transmission and processing device connected to the output end of the image sensor in the mobile phone body.

The position corresponding to the fingerprint collection area below the liquid crystal display screen is provided with a transparent electrode for sensing that a finger is pressed on the fingerprint collection area and outputting a corresponding signal to control the light-emitting aperture to energize and emit light. The transparent electrode is located on the liquid crystal display screen. and the image sensor.

The light-emitting aperture is conductively connected with the power supply circuit board provided in the mobile phone body.

The transparent protective screen is glass crystal.

A color filter is arranged between the transparent protective screen and the liquid crystal display screen.

The beneficial effects of the utility model are: when the intelligent integrated fingerprint identification mobile phone provided by the utility model is in use, when fingerprint identification is not required, the light-emitting aperture will not be energized to emit light. At this time, the liquid crystal display screen normally displays images, and When fingerprint identification is required, the light-emitting aperture will be powered on and emit light, so that the fingerprint collection area can be marked on the transparent protective screen, and the finger is pressed on the fingerprint collection area, and the light emitted by the light-emitting aperture as a light source is irradiated on the finger through the transparent protective screen. On the other hand, using the optical fingerprint collection technology, the reflected light is received by the image sensor to form a fingerprint image, and the fingerprint information is transmitted to the subsequent fingerprint transmission and processing device for corresponding processing. Since the fingerprint collection area is directly marked on the transparent protective screen of the mobile phone body, there is no need to add a fingerprint sensor in the keyboard area, so that no additional space is required for the mobile phone, and the miniaturization design of the mobile phone is used, and the fingerprint collection area is marked by the luminous aperture It is also convenient for the user to purposely press and press the finger, which is convenient for fingerprint collection.

Further, the luminous aperture is controlled to be energized through the transparent electrode, and when the transparent electrode senses pressure, the luminous aperture is controlled to emit light to mark the fingerprint collection area, and the control is simple and convenient.

Further, the light-emitting aperture is electrically connected to the power supply circuit board on the mobile phone body, so that no additional power supply is required.

Further, the transparent protective screen adopts glass crystal, which can improve the protection strength of the liquid crystal display screen.

Different from the prior art, the liquid crystal display in this embodiment is provided with a light-emitting aperture 3 as a light source and used to mark the fingerprint collection area 200 on the transparent protective screen 1, and the light-emitting aperture 3 is connected with the mobile phone body 100. Some power supply circuit boards are conductively connected, and the ring-shaped fingerprint collection area 200 of the luminous aperture 3 luminous mark is convenient for the user to press on the fingerprint collection area. The image sensor 7 receives the fingerprint image of the finger pressed on the fingerprint collection area 200 , and the mobile phone body 100 is also provided with an image transmission and processing device 8 connected to the output end of the image sensor 7 .

The transparent electrode 5 that emits light is located between the liquid crystal display 4 and the image sensor 7 .

The image sensor can adopt 500ppi or 600ppi CMOS sensor or CCD sensor.

When there is no need to collect fingerprints, the light-emitting aperture 3 will not be energized to emit light, and the liquid crystal display 4 displays images normally. At the same time, because the light-emitting aperture 3 is relatively thin, it will not have a great impact on the normal display of the liquid crystal display. When it is necessary to perform fingerprint collection and identification, the finger can be pressed directly on the screen of the mobile phone, the transparent electrode 5 senses the pressure, controls the light-emitting aperture 3 to energize and emit light, and the fingerprint collection area 200 is marked, and the user moves the finger to the fingerprint collection area 200 , using the optical fingerprint collection technology, the image sensor 77 collects the fingerprint image, and transmits it to the subsequent image transmission and processing device for processing.
