     DETAILED DESCRIPTION 
     The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only part but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present disclosure shall fall within the protection scope of the present disclosure. 
     A surrounding-screen display terminal, e.g., a surrounding-screen mobile phone, has an excessively large screen-to-body ratio design that occupies most area of the display terminal, which makes it more difficult to assemble internal components of the mobile phone. With the vigorous promotion of 5G technologies, a multi-antenna design makes the installation of an antenna module more complicated. For some surrounding-screen mobile phones in the related art, it is necessary to insert their antenna modules from surrounding openings of the surrounding screens during installation, of which the operation space is extremely limited. As a result, the assembling difficulty is improved and it is hard to ensure the assembling accuracy. 
     In order to solve the above technical problem, embodiments of the present disclosure provide a display screen and a display terminal. An antenna of the display terminal is reasonably arranged to reduce the assembling difficulty and the manufacturing cost of the whole device. 
     An embodiment of the present disclosure provides a display screen. The display screen may be an OLED display screen. As shown in  FIGS. 1 a  and  l    b, the display screen  100  includes a display region  11  and a non-display region  12  surrounding the display region  11 . The display region includes a plurality of sub-pixels  13 , and at least one of the plurality of sub-pixels  13  includes a pixel circuit and a light-emitting element  14 . For example, the light-emitting element  14  is an organic light-emitting diode (OLED). The pixel circuit is configured to drive the light-emitting element  14 , for example, to be turned on or off, and to adjust the luminance of the light-emitting element  14 . 
     The pixel circuit includes at least one metal layer. At least one antenna  17  is provided in the non-display region  12  and is disposed in the same layer as one of the at least one metal layer. The same layer in the embodiments of the present disclosure can be understood as being made of the same layer or several layers of materials, or being manufactured in the same patterning process, or being disposed on the same surface of the same layer structure. 
     As shown in  FIG. 1 b   , in some embodiments, the pixel circuit of the sub-pixel  13  includes a drive transistor  51  for driving the light-emitting element  14  and a storage capacitor  52 . 
     The drive transistor  51  includes an active layer  603 , agate  605 , a source  610  and a drain  611 . The gate  605  is disposed on a side of the active layer  603  and is insulated from the active layer  603 . For example, the active layer  603  and the gate  605  are spaced apart, and a first insulating layer  604  is disposed between the active layer  603  and the gate  605 . Both of the source  610  and the drain  611  are disposed on a side, distal from the active layer  603 , of the gate  605 , and are connected to the active laver  603 . The source  610  and the drain  611  are disposed in the same layer. 
     The storage capacitor  52  includes a first electrode plate  606  and a second electrode plate  608 . The first electrode plate  606  abuts against the second electrode plate  608 , and the second electrode plate  608  is disposed on a side, distal from the active layer  603 , of the first electrode plate  606  and is insulated from the first electrode plate  606 . For example, the first electrode plate  606  and the second electrode plate  608  are spaced apart, and a second insulating layer  607  is disposed between the first electrode plate  606  and the second electrode plate  608 . 
     The at least one antenna  17  may be disposed in the same layer as the gate  605 , or the source  610  and the drain  611 , or the first electrode plate  606  or the second electrode plate  608 . 
     As an example, in some embodiments, the first electrode plate  606  is disposed in the same layer as the gate  605 . In other examples, the second electrode plate  608  is disposed in the same layer as the gate  605 . 
     In addition, in some embodiments, one of the first electrode plate  606  and the second electrode plate  608  may be disposed in the same layer as the source  610 . For example, the second electrode plate  608  is disposed in the same layer as the source  610 ; or, the first electrode plate  606  is disposed in the same layer as the gate  605 , and the second electrode plate  608  is disposed in the same layer as the source  610 . 
     Referring to  FIG. 1 b   , as illustrated by a cross section of the sub-pixel  13  A-A, the sub-pixel  13  includes a base substrate  601 , a buffer layer  602 , an active layer  603 , a first insulating layer  604 , a gate  605 , a second insulating layer  607 , a second electrode plate  608 , a third insulating layer  609 , a source  610 , a passivation layer  612 , a planarization layer  613 , an anode layer  614 , a pixel defining layer  615 , a spacer layer  616 , an organic light-emitting layer  617 , a cathode layer  618 , a first inorganic encapsulation layer  619 , an organic encapsulation layer  620 , and a second inorganic encapsulation layer  621  that are disposed on a side of the base substrate  601  and are sequentially disposed in a direction distal going away from the base substrate  601 ; and the sub-pixel  13  further includes a first electrode plate  606  disposed in the same layer as the gate  605  and a drain  611  disposed in the same layer as the source  610 . 
     The source  610  and the drain  611  are connected to the active layer  603  through via holes, and the anode layer  614  is connected to the drain  611  through a via hole. In the display region  11 , a gate line  15  (referring to  FIG. 1 a   ) for transmitting a signal to the gate  603  may be disposed in the same layer as the gate  605 , and a data line  16  (referring to  FIG. 1 a   ) for transmitting a signal to the source  610  may be disposed in the same layer as the source  610  and the drain  611 . 
     In some embodiments, the display screen may be a bendable flexible display screen or an inflexible flat display screen. The following description takes the display screen as a bendable flexible display screen as an example. 
     The specific shape of the display screen  100  is not limited. As shown in  FIG. 1 a    and  FIG. 1 c   , in some embodiments, the display screen  100  is a flexible display screen applied to a surrounding-screen display terminal. The display screen  100  includes a first side  25   a , a second side  25   c , a third side  25   b  and a fourth side  25   d  that are successively connected, wherein the second side  25   c  and the fourth side  25   d  are curved, for example, substantially bent to be C-shaped, and the display screen  100  is substantially rectangular when flattened out. In some other embodiments, the display screen  100  substantially may also be in a parallelogram shape or other special shapes when flattened out. 
     In some embodiments, as shown in  FIG. 1 a   , the non-display region  12  further includes a take-up circuit region  27 , a first bonding region  18  disposed on a side, distal from the display region  11 , of the take-up circuit region  27 , and a first flexible circuit board  19  bonded to the first bonding region  18 . The first flexible circuit board  19  is bonded to a screen driving integrated circuit  20 , i.e., a screen driving IC  20 . 
     The display screen  100  may only have a display function, and the screen driving IC is a display driving IC that controls the display region to achieve the display function. The display screen  100  may also have both a display function and a touch function. For example, in an embodiment, the display screen  100  is a touch display screen with both display and touch functions, and the screen driving IC  20  is a touch driving IC that controls the display region  11  to achieve the touch function. Accordingly, the non-display region  12  may further include a display driving IC  21  disposed between the take-up circuit region  27  and the first flexible circuit board  19 . That is, the display driving IC  21  is bonded to a line between the flexible take-up circuit region  27  and the flexible first bonding region  18 . For example, the display driving IC  21  is bonded to the line between the take-up circuit region  27  and the first bonding region  18  by using the chip-on-PI (COP) encapsulation technology, such that the display driving IC  21  may be bent backward with a screen thereby further reducing the frame of the display terminal and achieving an approximately “borderless” effect. 
     In some embodiments, both of the display driving IC and the touch driving IC may be bonded to the first flexible circuit board  19  to achieve the display function and the touch function of the display region. 
     In some embodiments, a specific shape of the antenna  17  is not limited. For example, the antenna  17  may be a rectangular coiled antenna as shown in  FIG. 1 a    or an annular coiled antenna as shown in  FIG. 1 d   . In addition, the antenna  17  may also be designed in other shapes, e.g., an elliptical coiled shape. 
     In some embodiments, the display screen  100  is a touch display screen and the screen driving IC  20  is a touch driving IC. As shown in  FIGS. 1 a  and 1 c   , the non-display region  12  further includes a display driving IC  21  disposed between the take-up circuit region  27  and the first flexible circuit board  19 ; and in addition to the touch driving IC (the screen driving IC  20 ), an antenna IC  22  is bonded to the first flexible circuit board  19 . At least one antenna  17  is connected to the antenna IC  22  by wiring and the first bonding region  18  in the non-display region  12  sequentially. 
     The non-display region  12  includes an edge wiring region  23  for wiring. As an example, only part of the wiring is shown in the figure. The wiring of the edge wiring region  23  is used for transmitting a signal between the display region  11  and the first bonding region  18 , such as a display signal and/or a touch signal. The wiring of the edge wiring region  23  may also include anti-static wiring, etc. 
     In some embodiments, some wiring of the edge wiring region  23  is also configured to electrically connect the antenna  17  to the first bonding region  18  so as to realize transmission of a communication signal between the antenna  17  and the antenna IC  22 . As an example, the antenna  17  is disposed on the first side  25   a , i.e., the at least one antenna  17  is arranged adjacent to the first side  25   a . The first bonding region  18  is disposed on the third side  25   b , i.e., the first bonding region  18  is arranged adjacent to the third side  25   b . In the surrounding-screen display terminal (i.e., the display terminal  300  in  FIG. 1 c   ), the display screen  100  is bent to be U-shaped. The at least one antenna  17  is disposed on a back side of the surrounding-screen display terminal, i.e., a rear antenna design is adopted. The take-up circuit region  27 , the first bonding region  18  and the first flexible circuit board  19  are disposed on a front side of the surrounding-screen display terminal, and are folded on a back side of the display screen  100 . 
     The surrounding-screen display terminal further includes a supporting rear housing  200  disposed between the first side  25   a  and the third side  25   b  and arranged at a surrounding opening of the display screen  100  that is curved around. The supporting rear housing  200  is configured to support and fix the display screen  100  and other components (e.g., a camera). As an example, the number of the antenna  17  is not limited, for example, there may be one or two. In the case that the display screen includes two antennas  17 , both of the antennas  17  are disposed on the first side  25   b  and are arranged adjacent to the first side  25   a . One antenna  17  is arranged proximal to the second side  25   c , and the other antenna  17  is arranged proximal to the fourth side  25   d . The two antennas  17  are connected to the first bonding region  18  by the edge wiring region  23 . 
     In some embodiments, the display screen  100  is a touch display screen and the screen driving IC  20  is a touch driving IC. As shown in  FIGS. 2 a  and 2 b   , the non-display region  12  further includes a display driving IC  21  disposed between the take-up circuit region  27  and the first flexible circuit board  19 ; and in addition to the touch driving IC, an antenna IC  22  is bonded to the first flexible circuit board  19 . The at least one antenna  17  is connected to the antenna IC  22  by wiring and the first bonding region  18  in the non-display region  12  sequentially. 
     In some embodiments, both of the antenna  17  and the first bonding region  18  are disposed on the third side  25   b , i.e., both of the at least one antenna  17  and the first bonding region  18  are arranged adjacent to the third side  25   b . The display screen  100  is applied to the surrounding-screen display terminal (i.e., the display terminal  300  in  FIG. 2 b   ). The at least one antenna  17 , the take-up circuit region  27 , the first bonding region  18  and the first flexible circuit board  19  are disposed on the front side of the surrounding-screen display terminal, and are folded on the back side of the display screen  100 , i.e., a front antenna design is adopted. 
     The supporting rear housing  200  of the surrounding-screen display terminal is also disposed between the first side  25   a  and the third side  25   b  and is arranged at the surrounding opening of the display screen  100  that is curved around. The number of the antennas  17  is not limited, for example, there may be one or two. In the case that the number of the antennas  17  is two, as shown in  FIG. 2 a   , both of the antennas  17  are disposed on the first side  25   b , i.e., the two antennas  17  and the first bonding region  18  are both arranged adjacent to the third side  25   b , and the first bonding region  18  is disposed between the two antennas  17 . One antenna  17  is arranged proximal to the second side  25   c , and the other antenna  17  is arranged proximal to the fourth side  25   d.    
     In some embodiments, the display screen  100  is a touch display screen, and the screen driving IC  20  is a touch driving IC. As shown in  FIGS. 3 a  and 3 b   , the display screen further includes at least one second flexible circuit board  24  bonded to at least one antenna  17 . The non-display region  12  further includes a display driving IC  21  disposed between the take-up circuit region  27  and the first flexible circuit board  19 , and a second flexible circuit board  24  correspondingly bonded to each antenna  17 , wherein an antenna IC  22  is bonded to the second flexible circuit board  24 . 
     With this design, the antenna  17  is directly connected, without passing through the edge wiring region, to the second flexible circuit board  24  to which the antenna IC  22  is bonded, such that the structure of the edge wiring region can be simplified and the difficulty of an impedance matching design in a circuit can be reduced. In an embodiment of the present disclosure, at least one antenna  1  is disposed on and is arranged adjacent to the first side  25   a . The first bonding region  18  is disposed on the third side  25   b  and is arranged adjacent to the third side  25   b . The display screen  100  is applied to the surrounding-screen display terminal (i.e., the display terminal  300  in  FIG. 3 b   ), and the at least one antenna  17  is disposed on the back side of the surrounding-screen display terminal, i.e., a rear antenna design is adopted. The take-up circuit region  27 , the first bonding region  18  and the first flexible circuit board  19  are disposed on the front side of the surrounding-screen display terminal, and are folded on the back side of the display screen  100 . 
     The at least one second flexible circuit board  24  may be folded on the back side of the display screen  100  according to design requirements on a width of the non-display region on the back side of the surrounding-screen display terminal. In the case that the width of the non-display region on the back side of the surrounding-screen display terminal is large enough, the second flexible circuit board  24  may not be folded, either. 
     In some embodiments, the display screen  100  is a touch display screen and the screen driving IC  20  is a touch driving IC. As shown in  FIGS. 4 a  and 4 b   , the non-display region  12  further includes a display driving IC  21  disposed between the take-up circuit region  27  and the first flexible circuit board  19 , and a second flexible circuit board  24  correspondingly bonded to each antenna  17 . An antenna IC  22  is bonded to the second flexible circuit board  24 . 
     In some embodiments, the antenna  17  is disposed on the third side  25   b , i.e., both of the at least one antenna  17  and the first bonding region  18  are arranged adjacent to the third side  25   b . In the surrounding-screen display terminal (i.e., the display terminal  300  in  FIG. 4 b   ), the display screen  100  is bent to be U-shaped. The at least one antenna  17 , the at least one second flexible circuit board  24 , the take-up circuit region  27 , the first bonding region  18  and the first flexible circuit board  19  are disposed on the front side of the surrounding-screen display terminal, and folded on the back side of the display screen  100 , i.e., a front antenna design is adopted. 
     Where two antennas  17  are configured, as shown in  FIG. 4 a   , the two antennas  17  and the first bonding region  18  are all arranged adjacent to the third side  25   b , and the first bonding region  18  is disposed between the two antennas  17 .

     In view of the bendability of the flexible circuit board, during design of the first flexible circuit board  19  and the second flexible circuit board  24 , taking the first flexible circuit board  19  as an example, a width B of the flexible portion  26   a , a bonding width L of the flexible portion  26   a  a width C of the inflexible portion  26   b , and a bending radius R of the flexible portion  26   a  meet: B−C≥L+πR. To meet design requirements on these parameters, a folding process can be completed as long as a gap A of the display screen  100  curved around allows a suction nozzle that adsorbs the flexible portion  26   a  to be extended therein. 
     According to the display screen  100  in some embodiments, at least one antenna  17  is integrated in the non-display region  12  and is disposed in the same layer as at least one metal layer of the pixel circuit of the sub-pixel  13 . In the case that the display screen  100  is applied to the display terminal  300 , it is unnecessary to additionally provide and assemble an antenna module for the display terminal, which, compared with the related art, can reduce the assembling difficulty and the manufacturing cost of a whole device. In addition, the antenna  17  is designed in the non-display region  12  of the display screen  100 , such that the area of the non-display region can be fully utilized. The number and positions of the antennas  17  can be flexibly designed as required, and hence the range of applicable products is wider. Moreover, the design of the display screen  100  is especially suitable for surrounding-screen display terminal products. In addition to the surrounding-screen display terminals, the display screen  100  may also be applicable to other curved display terminals or flat display terminals to achieve similar benefits as mentioned above.

The non-display region  12  includes at least one antenna  17  disposed in the same layer as one of the at least one metal layer. The display screen in the display terminal  300  may be any of the display screens  100  described above. As stated above, compared with the related art, it is unnecessary to provide and assemble an antenna module for the display terminal, such that the assembling difficulty and the manufacturing cost of a whole device are greatly reduced.
