CROSS-REFERENCE TO RELATED APPLICATION

The present application is a national stage of International Application No. PCT/CN2019/098721 filed on Jul. 31, 2019, the disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to a field of electronic technologies, and more specifically to an electronic apparatus.

BACKGROUND

Display screens of electronic apparatuses such as mobile phones are no longer provided on one surface of the devices, and electronic apparatuses with display screens both on front and back are gradually emerging, which makes fingerprint identification through front and back screens become a requirement.

For example, a wraparound display screen is a brand-new display solution of mobile phone. In the related arts, the wraparound display screen surrounds the mobile phone, so that the mobile phone has a display screen both on front and back. Screen-to-body ratio of mobile phone with a wraparound display screen is much greater than that with a single-sided display screen, and correspondingly, space for a fingerprint identification module in the mobile phone employing a wraparound display screen is greatly compressed. How to set up the fingerprint identification module in the limited space to implement fingerprint identification through the front and back screens has become a problem to be solved.

SUMMARY

In order to overcome the problems in the related art, the present disclosure provides an electronic apparatus.

According to a first aspect of the embodiments of the present disclosure, there is provided an electronic apparatus, including: a display screen, a reflector and a sensor, wherein the electronic apparatus includes a plurality of surfaces, the display screen includes a first display region and a second display region that are respectively located on different surfaces of the electronic apparatus, and the display screen can transmit light;

the reflector and the sensor are arranged inside the electronic apparatus, and light transmitted from the first display region and the second display region is reflected by the reflector and then irradiated on the sensor; and

the sensor is configured to generate an electric signal for fingerprint identification based on the light received.

In a probable implementation, a first lens and a second lens are further arranged inside the electronic apparatus, wherein the first lens is configured to converge light transmitted from the first display region to the reflector, and the second lens is configured to converge light transmitted from the second display region to the reflector.

In a probable implementation, the reflector includes a first reflecting prism and a second reflecting prism;

light transmitted from the first display region is capable of being reflected by a reflecting surface of the first reflecting prism and then irradiated on the sensor; and/or

light transmitted from the second display region is capable of being reflected by a reflecting surface of the second reflecting prism and then irradiated on the sensor.

In a probable implementation, the reflecting surface of the first reflecting prism is a concave surface, and/or, the reflecting surface of the second reflecting prism is a concave surface.

In a probable implementation, the reflector includes a first concave mirror and a second concave mirror;

light transmitted from the first display region is capable of being reflected by a reflecting surface of the first concave mirror and then irradiated on the sensor; and/or

light transmitted from the second display region is capable of being reflected by a reflecting surface of the second concave mirror and then irradiated on the sensor.

In a probable implementation, an outer surface of the display screen is covered with a transparent cover plate which can transmit light.

In a probable implementation, an inner surface of the display screen is provided with a display screen support, and a region of the display screen support opposite to the reflector can transmit light.

In a probable implementation, the display screen support is made of a transparent material.

In a probable implementation, the display screen support is made of a non-transparent material; and

a region of the display screen support opposite to the reflector is provided with a through hole which can transmit light.

In a probable implementation, the through hole is filled with a transparent material.

The technical solutions provided by the embodiments of the present disclosure can include the following beneficial effects: according to the present disclosure, the reflector and the sensor are arranged inside the electronic apparatus, and the light transmitted from the first display region or the second display region located on different surfaces is reflected by the reflector and then irradiated on the sensor, so that the sensor generates the electric signal for fingerprint identification based on the light received. Therefore, a solution of sharing the sensor under the display screen is proposed, which only employs a single sensor to implement fingerprint collection and identification at display region on different surface of the display device, occupying a small space without additional sensors, so that the hardware cost is greatly reduced. Moreover, the present disclosure does not need to open holes in the display screen, which effectively increases the effective display region of the display screen, and further increases the hermeticity and mechanical strength of the electronic apparatus.

It should be understood that the above general description and the following detailed description are exemplary and explanatory, and are not intended to limit the present disclosure.
