All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention. As shown in fig. 1, the display device includes a first display screen 10 and a second display screen 20, wherein the first display screen 10 is a main display screen, and a screen body with ultra-narrow four sides and even without a frame is adopted, such as a frameless capacitive touch display screen, and the shape of the capacitive touch display screen is a rectangle or a rounded rectangle. Referring to fig. 1 to 3, the second display screen 20 is disposed on a side surface of the first display screen 10, the first display screen 10 and the second display screen 20 are seamlessly spliced, and a transparent cover plate (such as a glass cover plate) may be disposed on a front surface of the second display screen 20 to integrate the first display screen 10 and the second display screen, so that the first display screen 10 becomes a complete main screen area.
The display device is usually, but not necessarily, a portable display device, and may specifically be a mobile phone, a tablet computer, a laptop computer, a personal digital assistant, or the like, and the present invention will describe embodiments by taking a mobile phone as an example, but it is understood that the present invention is not limited to a mobile phone.
According to the display device provided by the embodiment of the invention, the second display screen is additionally arranged on the side surface of the main display screen, and the fingerprint identification area is arranged on the second display screen, so that the main display screen does not need to be cut for fingerprint identification, waste is avoided, the screen occupation ratio is increased, the visual aesthetic feeling is enhanced, the front fingerprint identification function can be realized, and the user experience is improved. In an embodiment of the present invention, as shown in fig. 1 to 3, the second display screen 20 is disposed on the left side of the first display screen 10, and the fingerprint identification area 21 is disposed on the lower portion of the second display screen 20, that is, the fingerprint identification area 21 is located on the lower left of the display screen, so that the user can conveniently perform one-handed operation.
Of course, considering that some users prefer to press a finger on the middle upper portion of the mobile phone for fingerprint unlocking operation due to different holding habits, the fingerprint identification area 21 may be disposed on the upper portion of the second display screen 20, and the specific position of the fingerprint identification area 21 is not limited in the present invention. The second display 20 may be provided on the right side of the first display 10, and similarly, the fingerprint identification area 21 may be provided on the upper or lower portion of the second display 20.
As shown in fig. 3 and 4, the fingerprint identification module 22 corresponding to the fingerprint identification area 21 is disposed on the back of the second display screen 20, and in other embodiments, the fingerprint identification module 22 may be embedded in the second display screen 20, and both of these two ways can realize the front fingerprint identification function.
The fingerprint recognition module 22 may be an optical fingerprint sensor module or a semiconductor fingerprint sensor module, as long as the front fingerprint recognition function can be achieved, which is not limited in the present invention. The fingerprint identification module 22 may be triggered by one or more of a temperature sensor, a capacitive touch sensor, a pressure sensor and a tact mechanical switch disposed on the back of the second display screen 20.
In an embodiment of the present invention, the fingerprint identification module 22 includes an optical fingerprint sensor, which is an optical fingerprint sensor module.
In one embodiment, the optical fingerprint sensor is triggered by a temperature sensor, when the object to be captured (such as a finger) approaches the fingerprint identification area 21 of the second display 20, the temperature sensor detects a temperature change, and then the processor lights up the pixel units corresponding to the fingerprint identification area 21, so that the light emitted by the pixel units can irradiate on the object to be captured. The pixel unit is lighted for a long time to clearly photograph the target pattern, and the long time is not needed. The light reaches the optical fingerprint sensor through reflection again to form the optical image of being gathered the target, fingerprint identification module 22 compares this image with the fingerprint image of storage in the system again, finally accomplishes fingerprint identification and judgement operation.
In another embodiment, the optical fingerprint sensor is triggered by a capacitive touch sensor, when a captured object (e.g. a finger) of a user touches the fingerprint identification area 21 of the second display screen 20, after the capacitive touch sensor senses a touch action and a touch position, a pixel unit corresponding to the fingerprint identification area 21 is turned on by the processor, and light emitted by the pixel unit can be irradiated onto the captured object. The light reaches the optical fingerprint sensor through reflection again to form the optical image of being gathered the target, fingerprint identification module 22 compares this image with the fingerprint image of storage in the system again, finally accomplishes fingerprint identification and judgement operation.
Similarly, if the optical fingerprint sensor is triggered by a pressure sensor or a touch mechanical switch, when the collected object (such as a finger) presses the fingerprint identification area 21 of the second display screen 20, the pressure sensor or the touch mechanical switch senses the pressing action and the pressing position, and then transmits the signal to the processor, and the processor controls and lights the pixel unit, so that the optical fingerprint sensor finishes the collection of the fingerprint image, and finally finishes the fingerprint identification and judgment operation.
When the fingerprint recognition module 22 is a semiconductor fingerprint sensor module, it may also be triggered by one or more of a temperature sensor, a capacitive touch sensor, a pressure sensor and a touch mechanical switch disposed on the back of the second display 20.
Because the fingerprint identification area 21 of second display screen 20 does not need the touch-control effect similar to the main display screen, so only need fingerprint identification module 22 and above-mentioned temperature sensor, capacitanc touch sensor, pressure sensor and touch one or more cooperation among the mechanical switch can realize positive fingerprint identification function, its fingerprint identification mode under being similar to a screen more simple and easy, this kind of design simple structure, the operation complexity is lower, can carry out the volume production. When the above-mentioned sensor and fingerprint identification module 22 combination use, only when the sensor perception is in the touch of the fingerprint identification region 21 of second display screen 20 or be close to the action after, just start the luminous illumination of the pixel unit that corresponds the region, reduced the loss of electric quantity.
In an embodiment of the present invention, the fingerprint identification area 21 of the second display 20 is a non-physical key.
For example, when the display device senses that the captured object (e.g. a finger) touches or approaches the fingerprint identification area 21, the fingerprint identification area 21 may be displayed in the form of a virtual fingerprint key, which may be in the form of a white circle, an oval, or the like, to prompt the user to press a fingertip against the fingerprint identification area 21 to input a fingerprint.
In addition, since the fingerprint identification area 21 of the second display 20 does not need a display effect similar to that of the main display, it is sufficient if it can be used for fingerprint identification. A fingerprint pattern may be printed on the fingerprint recognition area 21 of the second display screen 20 in order to facilitate the user to find the fingerprint sensing area more accurately. If the optical fingerprint sensor and the temperature sensor are selected to cooperate to perform fingerprint identification, when a collected object (such as a finger) is close to the fingerprint identification area 21, the temperature sensor detects temperature change and informs the processor, and the processor enables the screen to be lightened. Therefore, when the screen is bright, the fingerprint pattern appears in the fingerprint identification area 21, the user can find the induction area quickly according to the pattern, specifically, the fingerprint pattern can be controlled to be displayed on the fingerprint identification area 21 statically or dynamically for a short time, and the user can use the fingerprint pattern conveniently and a brand new experience is brought to the user.
In another embodiment of the invention, in order to enable the user to quickly and accurately find the fingerprint identification sensing position in the screen-off standby state and avoid the embarrassment of blind touch, the fingerprint identification area 21 can be displayed in the screen-off state. For example, when a power-on key on the side of the mobile phone is pressed, the mobile phone enters a screen-off standby state, in this state, the pixel unit corresponding to the fingerprint identification area 21 can be controlled to light up through a local control technology, and at this time, the fingerprint identification area 21 can also be displayed in a form of a fingerprint identification virtual key, so that a user can quickly identify the position of fingerprint identification in the screen-off standby state, and an acquired target (such as a finger) is placed at the position to perform an unlocking action.
Meanwhile, in order to reduce power consumption, the fingerprint identification area 21 may be controlled to be turned on and off at a certain frequency, or only a few pixel units corresponding to the outer edge of the fingerprint identification area 21 may be turned on to enable a user to identify the outline of the fingerprint identification area 21.
The display of the first display screen 10 and the second display screen 20 may be individually controlled by a controller inside the display device. For example, the controller may control the second display 20 to be in a sleep state in a case of controlling the first display 10 to be lit, may control the second display 20 to be lit in a case of controlling the first display 10 to be in the sleep state, or may control the first display 10 and the second display 20 to be in the sleep state or in the lit state at the same time.
The second display screen 20 may be an Active-Matrix Organic Light Emitting Diode (AMOLED) screen or an electronic ink screen, so as to reduce the power consumption of the device. Of course, the second display 20 may also be a liquid crystal display or an electrowetting display, and the invention is not limited thereto.

Status bar area 232 is used to display status information such as signal strength, time information, remaining capacity, etc., which is convenient for the user to check at any time.
Since in many cases, the user may not be involved in using the specific functions of the device, and may only be able to view status information such as time and power, or determine whether there is an incoming call or other notification messages such as WeChat and SMS, and the frequency of the occurrence of such a situation is high, the user may individually light the second display 20 by separately controlling the display technologies of the first display 10 and the second display 20, and may view the notification or status information without lighting the first display 10. Therefore, the first display screen 10 can be in the dormant state for a long time, and the electric quantity is saved.
In an embodiment of the invention, the second display 20 is an in-cell touch display, such as an in-cell touch organic electroluminescent display or an in-cell touch liquid crystal display. In the present embodiment, a notification message, such as an incoming call or a short message, may be displayed in the shortcut menu bar area 231 while a corresponding operation button for the notification message is displayed.
For example, when the call alert message is displayed in the shortcut menu bar area 231 for the call icon, the operation buttons for the incoming call, such as an answer button and a reject button, may also be displayed at the same time. For another example, when the content of the notification message is displayed in the shortcut menu bar area 231 for the short message icon, a delete button or a reply button may be simultaneously displayed. Thus, the user can directly perform corresponding operations on the operation buttons on the second display screen 20, power consumption is reduced, and the use by the user is facilitated.
In an embodiment of the invention, the display device further comprises one or more of a front camera, a front flash and a distance sensor, one or more of which are also located at the side of the first display screen 10, at the same side as the second display screen 20 and above the second display screen 20.
