Specific embodiments of the present disclosure have been shown by way of the above drawings and will be described in more detail below. These drawings and the written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.
Detailed Description
For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.
Currently, housings of various terminals such as cellular phones and tablet computers are generally plate-shaped, and one of two larger faces of the plate-shaped housing may be provided with a display screen. In the related art, the fingerprint recognition area is generally set in two ways:
the first way is: the fingerprint identification area is arranged on one surface of the shell where the display screen is arranged.
As shown in fig. 1, the fingerprint recognition area is schematically shown when the fingerprint recognition area is disposed on one surface of the housing, on which the display screen is disposed. In fig. 1, the fingerprint recognition area 12 and the display 13 are disposed on the same surface of the housing 11, and it can be seen that it is difficult to touch the fingerprint recognition area 12 after the user clicks a key (e.g., clicks a key on a side of the terminal with a thumb while holding the terminal with one hand). Furthermore, the presence of the fingerprint recognition area 12 severely reduces the screen duty cycle of the terminal (the screen duty cycle may be the ratio of the area of the display screen to the area of the face on the terminal). The high screen ratio is a development trend of the current terminal, so that the current design requirement is difficult to meet in this way.
In addition, in fig. 1, the fingerprint recognition area 12 disposed at the bottom of the display 13 may also interfere with other components such as an antenna component in the terminal, which increases the difficulty in disposing the fingerprint recognition area 12.
The second way is: the fingerprint identification area is arranged on one surface of the shell where the display screen is not arranged.
As shown in fig. 2, the fingerprint recognition area is disposed on a side of the housing where the display screen is not disposed. In fig. 2, the fingerprint recognition area 12 and the display are provided on different sides of the housing 11, and it can be seen that it is difficult to touch the fingerprint recognition area 12 after the user clicks a key (e.g., clicks a key on a side of the terminal with a thumb while holding the terminal with one hand).
In addition, the side of the housing 11 where the display screen is not provided is typically provided with a camera 14, and the fingerprint recognition area 12 may collide with the area where the camera 14 is located. And may occupy the space in which the battery is located within the body.

In summary, in the terminal provided by the embodiment of the present disclosure, by combining the fingerprint identification area with the area occupied by the key, when the user clicks the key, the user can touch the fingerprint identification area at the same time. The problem that the step of unlocking the terminal by the user is complicated in the related art is solved. The effect of simplifying the step of unlocking the terminal by the user is achieved.
Alternatively, as shown in fig. 3, the number of sub-recognition areas 321 is 2, and two sub-recognition areas 321 are located at opposite sides of the key hole. Thus, the user can conveniently touch the fingerprint identification area when pressing the key.
Optionally, the side surface of the housing 31 is elongated, and at least two sub-recognition areas 321 are arranged along the length direction f of the side surface of the housing 31.

Alternatively, the fingerprint sensor 34 may be an ultrasonic fingerprint sensor or an optical fingerprint sensor. When the fingerprint sensor 34 is an optical fingerprint sensor, the side of the housing 31 is made of a transparent material.
Alternatively, the fingerprint sensor 34 is a thin film sensor. The film sensor is attached to the inner wall of the housing 31. The thin film sensor may have a thickness of between 0.1 millimeters (mm) and 0.2 mm. The film sensor may be flexible to conform to the inner wall of the housing 31.

Optionally, as shown in fig. 3, the area occupied by the fingerprint identification area 32 on the side surface of the housing 31 is larger than the area occupied by the key 33 on the side surface of the housing 31, so that the area of the fingerprint identification area 32 can be increased, and the success rate of fingerprint identification can be improved. Alternatively, as shown in fig. 5, when the key 33 is a physical key, the key 33 may be in contact with a Dome 331 inside the case 31, and the Dome 331 may be in contact with a mechanical plug (english: mechanical stopper) 332. The dome 331 may be used as a trigger switch, and when the key 33 presses the dome 331, the trigger switch may be turned on, and the dome 331 may be connected to the main board 35 (not shown in fig. 11) so as to transmit a signal triggered by the key 33 to the main board 35. And the mechanical plugs 332 are used as support structures for the dome 331.

The fingerprint sensor in the related art is usually a sensor based on a silicon-based technology, and the sensor is difficult to bend, so that after the sensor based on the silicon-based technology is arranged on the side surface of the shell, the area of the sensor based on the silicon-based technology is usually smaller, and the success rate of fingerprint identification is not high. In the embodiment of the disclosure, the thin film sensor based on the fingerprint identification technology is used as the fingerprint sensor, so that the fingerprint sensor can be bent along with the side surface of the shell, the area of the fingerprint identification area is increased, and the success rate of fingerprint identification is improved.
Optionally, the fingerprint sensor 34 comprises a plurality of sensor elements arranged in an array. The plurality of sensor elements may each perform an acquisition of a fingerprint parameter. Thus, when one or more sensor elements fail or fingerprint parameters are not collected, the terminal can still collect the fingerprint parameters of the user, and the success rate of fingerprint identification is improved.
