     DETAILED DESCRIPTION 
     In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present disclosure. It is obvious that the described embodiments are part of the embodiments rather than all embodiments of the present disclosure. All other embodiments obtained by one of ordinary skill in the art based on the described embodiments of the present disclosure without the need for creative work are within the scope of the present disclosure. 
     With the development of science and technology, the operation frequency of display devices is getting higher and higher, and people have higher and higher requirements for the display area of display devices. In the related art, the display area of the display device is generally increased by reducing the area of the bezel of the display device and increasing the area of the display region of the display screen. Since devices such as a receiver, a loudspeaker, a camera and the like, which have a certain size, are generally required to be disposed in the bezel of the display device, the reduction in the area of the bezel of the display device and the increase in the area of the display screen are limited, resulting in a small display area of the display device. 
     Embodiments of the present disclosure provide a display device having a relative larger display area. 
       FIG. 1  is a front view of a display device according to an embodiment of the present disclosure; and  FIG. 2  is a rear view of a display device according to an embodiment of the present disclosure. Referring to  FIGS. 1 and 2 , the display device includes a housing  101  which is provided with thereon with a first display component  102 , an auxiliary display component  103  and a second display component  104  that are connected in sequence, wherein the first display component  102  and the second display component  104  are oppositely disposed. 
     In summary, in the display device according to the embodiment of the present disclosure, since the housing is provided with the first display component, the auxiliary display component and the second display component that are connected in sequence and the first display component and the second display component are oppositely disposed, the display region is provided on each of a front side, a rear side and a side edge of the display device, thereby increasing the display area of the display device. 
     It should be noted that in the display device according to the embodiment of the present disclosure, each display component may be embedded into the housing of the display device to improve the smoothness of the appearance of the display device. 
     The display device shown in  FIGS. 1 and 2  is exemplified by the auxiliary display component  103  disposed on the right edge of the housing  101 . In practical applications, the auxiliary display component  103  may alternatively be disposed at other side edges of the housing  101  (e.g., a left side edge, an upper side edge, or a lower side edge). In addition, the display device shown in  FIGS. 1 and 2  is exemplified that the first display component  102  and the second display component  104  are flat display components, and the auxiliary display component  103  is a curved display component. In practical applications, the first display component  102  and the second display component  104  may alternatively be curved display components, and the auxiliary display component  103  may also be a flat display component. The embodiments of the present disclosure do not limit the first display component  102 , the auxiliary display component  103 , and the second display component  104  to a flat display component or a curved display component. 
       FIG. 3  is an exploded structural view of a display screen according to an embodiment of the present disclosure. It should be noted that the display screen may include the first display component  102 , the auxiliary display component  103 , and the second display component  104  as illustrated in  FIGS. 1 and 2 . As illustrated in  FIG. 3 , the first display component  102 , the auxiliary display component  103 , and the second display component  104  are connected into an integrated piece  10 , and each of the first display component  102 , the auxiliary display component  103 , and the second display component  104  is formed of flexible material. 
     Since the three components are connected into an integrated piece and each is formed of flexible material, it is possible to obtain the three components by bending a large flexible display screen, thereby increasing manufacturing efficiency of the display device. For example, while manufacturing the first display component, the auxiliary display component and the second display component, the flexible display screen having the shape as illustrated in  FIG. 3 , which is an irregular display screen, may be manufactured firstly and then bending the flexible display screen to obtain the three components. 
     Further, referring to  FIGS. 1, 2 and 3 , the display area of the first display component  102  may be larger than the display area of the second display component  104 . In practical applications, the display area of the first display component  102  may alternatively be less than or equal to the display area of the second display component  104 , which is not limited in this embodiment of the disclosure. 
     Optionally, at least one of the first display component  102 , the auxiliary display component  103 , and the second display component  104  may have a touch function. In the present embodiment, in the case where the auxiliary display component  103  has a touch function, the auxiliary display component  103  may display a virtual switch button or a virtual volume button. The user may touch the virtual switch button on the auxiliary display component  103  to switch on or off the display screen. The user may also touch the virtual volume button displayed on the auxiliary display component to achieve the purpose of adjusting the volume. In addition, it is possible to avoid forming openings at the edge of the casing of the display device due to the need of the physical switch button or the physical volume button, thereby improving the manufacturing yield of the housing of the display device. 
     Optionally, at least one of the first display component  102 , the auxiliary display component  103 , and the second display component  104  has a fingerprint recognition function. It should be noted that the display component having a fingerprint recognition function may be a fingerprint recognition display screen, or the display component having a fingerprint recognition function may be a display screen provided with a fingerprint recognition sensor on the display side thereof. When the display component having the fingerprint recognition function is a fingerprint recognition display screen, it is possible to avoid forming openings on the cover of the display device due to the need of the fingerprint recognition component, so that the manufacturing yield of the cover of the display device can be improved. 
     Further, in the case where the second display component  104  has a fingerprint recognition function, the display area of the second display component  104  may coincide with the fingerprint recognition area, so that when unlocking the device with fingerprint, the user is only required to touch any area in the display area of the second display component  104  with a finger. Accordingly, the user may find the area for fingerprint recognition in the display device more quickly, thereby improving the efficiency of fingerprint unlocking. 
     Optionally, the display device may further include: a first cover (not illustrated in  FIG. 1 ,  FIG. 2  or  FIG. 3 ) that may cover the first display component  102  and the auxiliary display component  103  and a second cover (not illustrated in  FIG. 1 ,  FIG. 2  or  FIG. 3 ) that may cover the second display component  104 . For example, if the first display component is a flat display component, the auxiliary display component is a curved display component, and the second display component is a flat display component, then the first cover may include a planar portion and a curved portion connected to each other, and the second cover may be a planar cover. In practical applications, the first cover may alternatively cover the first display component  102 , while the second cover may alternatively cover the second display component  104  and the auxiliary display component  103 . The first cover may be a flat cover, and the second cover may include a planar portion and curved portion connected to each other, which is not limited in this embodiment of the disclosure. 
     In the case where the first cover covers the first display component  102  and the auxiliary display component  103 , the connection between the first cover and the second cover is located at the transition of the auxiliary display component  103  and the second display component  104 . Therefore, when the user is at the display side of the first display component  102 , the user will not see a connection gap at the transition of the first display component  102  and the auxiliary display component  103 , and the display effect of the display device is improved. In addition, when manufacturing the cover by partitioning it, it is also possible to increase the manufacturing yield of the cover and facilitate mass production. 
     Referring further to  FIGS. 1 and 2 , the display device may further include: a first image capturing component  105 , a second image capturing component  106 , and a face recognition component (not shown in  FIG. 1  or  FIG. 2 ), and the first image capturing component  105  and the second image capturing component  106  are connected to the face recognition component. The first image capturing component  105  may be disposed adjacent to the first display component  102 , the second image capturing component  106  may be disposed adjacent to the second display component  104 , and an image capturing side of the first image capturing component  105  may be a display side of the first display component, and an image capturing side of the second image capturing component  106  may be a display side of the second display component. 
     It should be noted that the face recognition component in the display device may be a separate face recognition chip, or may be a central processing unit with a face recognition function, which is not limited in this embodiment of the disclosure. The first image capturing component  105  and the second image capturing component  106  may be two-dimensional image capturing components or three-dimensional image capturing components, which are not limited in this embodiment of the disclosure. 
     Optionally, the display device may further include a fill light  107  disposed adjacent to the second display component  104 , and a light emitting side of the fill light  107  may be a display side of the second display component  104 . 
     In addition, the display device may further include: a rear camera  108  disposed adjacent to the second display component  104  and a front camera (not illustrated in  FIG. 1 ) disposed adjacent to the first display component  102 . An image capturing side of the rear camera  108  may be a display side of the second display component  104 , and an image capturing side of the front camera may be a display side of the first display component  102 . 
     It should be noted that, the front camera may be integrated with the first image capturing component as one component, and the rear camera may be integrated with the second image capturing component as one component. In the embodiment of the disclosure, the example is that the front camera is integrated in the first image capturing component, and the rear camera and the second image capturing component are mutually independent, which is not limited in this embodiment of the present disclosure. 
     When the user needs to take a selfie, the user may be at the display side of the second display component  104  and use the rear camera  108  to take a selfie. In this case, the second display component  104  may display the face image captured by the rear camera  108 . Moreover, the user may also turn on the fill light  107  to fill the light, which improves the photographing performance of the display device. Generally, the resolution of the rear camera is higher than that of the front camera, thus improving the photographing effect of the display device. 
     In addition, a third display component may be disposed on the housing  101  of the display device as illustrated in  FIGS. 1 and 2 . For example,  FIG. 4  is a front view of another display device according to an embodiment of the present disclosure. As illustrated in  FIG. 4 , on the basis of  FIG. 1 , the third display component  109  is further disposed on the housing  101  of the display device. The third display component  109  is connected to the first display component  102  and is disposed opposite to the auxiliary display component  103 . Since the third display component  109  may be further disposed on the housing of the display device, and the third display component  109  is connected to the second display component  102  and is disposed opposite to the auxiliary display component  103 , then the display device has display regions on the front side, the rear side and both the side edges, which further increases the display area of the display device. 
     In summary, in the display device provided by the embodiment of the present disclosure, the first display component, the auxiliary display component, and the second display component that are connected in sequence are disposed on the housing of the display device, and the first display component and the second display component are disposed oppositely on the housing, and thus the display device has display regions on the front side, the rear side and a side edge, which increases the display area of the display device. 
     An embodiment of the present disclosure further provides a method for controlling a display device applicable to a control device of the display device as illustrated in  FIG. 1  or  FIG. 2 . The method for controlling the display device may include: controlling at least one display component of the first display component, the auxiliary display component and the second display component to perform a display operation. 
     For example,  FIG. 5  is a method flowchart of a method for controlling a display device according to an embodiment of the present disclosure. As illustrated in  FIG. 5 , the controlling at least one display component of the first display component, the auxiliary display component and the second display component to perform a display operation may particularly include the following steps. 
     In step  201 , a first image capturing component is controlled to capture a first image. 
     In step  202 , a second image capturing component is controlled to capture a second image. 
     It should be noted that the first image capturing component and the second image capturing component may be two-dimensional image capturing components or three-dimensional image capturing components. For example, in the case where both the first image capturing component and the second image capturing component are two-dimensional image capturing components, the first image and the second image are both two-dimensional images, for example, two-dimensional face images. In the case where both the first image capturing component and the second image capturing component are three-dimensional image capturing components, the first image and the second image are both three-dimensional images, for example, three-dimensional face images. 
     For example, the two-dimensional image capturing component may be a visible light imaging component, and the three-dimensional image capturing component may be an IR imaging component or an ultrasonic imaging component. 
     In step  203 , a face recognition component is controlled to recognize whether a face image is included in the first image and the second image. 
     For example, the face recognition component extracts a feature from the first image after the first image capturing component captures the first image, judges whether a similarity between the feature and a feature of a human face reaches a preset similarity threshold, and determines that a face image is included in the first image if the similarity reaches the preset similarity threshold while determines that no face image is included in the first image if the similarity does not reach the preset similarity threshold. 
     Similarly, the face recognition component extracts a feature from the second image after the second image capturing component captures the second image, judges whether a similarity between the feature and a feature of a human face reaches a preset similarity threshold, and determines that a face image is included in the second image if the similarity reaches the preset similarity threshold while determines that no face image is included in the second image if the similarity does not reach the preset similarity threshold. 
     In step  204 , the display component is controlled to perform a display operation according to the image including the face image. 
     For example, when the first image includes a face image, the control device of the display device may control the first display component to perform the display operation. When the second image includes a face image, the control device of the display device may control the second display component to perform the display operation. When both the first and second images include face images, the control device of the display device may control both the first and second display components to perform the display operation. 
     It should be noted that, the display operation performed by the first display component under the control of the control device of the display device is a first display operation, and the display operation performed by the second display component under the control of the control device of the display device is a second display operation. The first display operation may be the same as the second display operation, or the first display operation is different from the second display operation, which are not limited in this embodiment of the disclosure. 
     For example,  FIG. 6  is an interface displayed on a second display component according to an embodiment of the present disclosure. As illustrated in  FIG. 6 , the interface A displayed on the second display component  104  may include: time information in the middle region A 1  of the interface A, weather information in the upper left region A 2  of the interface A, message alert information in the lower left region A 3  of the interface A, and date information in the lower right region A 4  of the interface A. In the present embodiment, the time information may be in form of “18:05”, the weather information may be in form of “Sunny to Cloudy”, the message alert information may be in form of “New Message Incoming”, and the date information may be in form of “20XX/XX/XX”. In the present embodiment, X may represent any integer, and the plurality of Xs illustrated in  FIG. 5  may be different integers. 
     In summary, in the method for controlling the display device according to the embodiment of the present disclosure, the display device may control the first display component or the second display component to perform the display operation according to the position of the user, which may improve the display performance of the display device. In addition, in the case where the second display component has a display area smaller than that of the first display component, the area of the display region may be smaller when the second display component is controlled to perform the display operation, which may reduce the power consumption of the display device. 
       FIG. 7  is a structural view of a control device of a display device applicable to the display device as illustrated in  FIG. 1  or  FIG. 2 , according to an embodiment of the present disclosure. As illustrated in  FIG. 7 , the control device  30  of the display device may include: 
     a first capturing module  301 , configured to control a first image capturing component to capture a first image; 
     a second capturing module  302 , configured to control a second image capturing component to capture a second image; 
     a recognition module  303 , configured to recognize whether a face image is included in the first image and the second image; 
     a first display module  304 , configured to control a first display component to perform a display operation in the case where the first image includes the face image; and 
     a second display module  305 , configured to control a second display component to perform a display operation in the case where the second image includes the face image. 
     In summary, in the control device of the display device according to the embodiment of the present disclosure, the recognition module may recognize a position of the user, and the first display module may control the first display component to perform a display operation according to the recognition result of the recognition module, and the second display module may also control the second display component to perform a display operation according to the recognition result of the recognition module, thereby improve the display performance of the display device. In addition, in the case where the second display component has a display region of an area smaller than that of display region of the first display component, the area of the display region is smaller when the second display component is controlled to perform the display operation, which may reduce the power consumption of the display device.
