[0036] In the related art, the display screen module with NFC function usually sets the NFC coil on the FPC, and sets the NFC coil as an independent area. However, the design of setting the NFC coil as an independent area in the above display screen module requires a large space on the FPC, which affects the layout of other components on the FPC. In addition, the NFC coils are concentrated in the same area, which makes the NFC function area small, affecting the convenience of using the NFC function of the display screen module.

[0037] In response to the above problems, an embodiment of the present application provides a display screen module, which can effectively reduce the occupied area of ​​the NFC coil on the control circuit board, facilitate the layout of other components on the control circuit board, and at the same time increase the effective area of ​​the NFC coil, thereby improving the convenience of the NFC function of the display screen module.

[0038] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0039] Figure 1 It is a structural schematic diagram of a display screen module shown in an embodiment of the present application.

[0040] See also Figure 1 The display screen module of the present application includes: a display screen 110 , a control circuit board 120 and an NFC coil 130 .

[0041] The display screen 110 is used for displaying patterns or images. It is understood that the display screen 110 can be used to display static patterns or dynamic images. The colors of the patterns or images can be black and white or color, which is not limited here.

[0042] The control circuit board 120 is used to control the display screen to display patterns or images. The control circuit board 120 is electrically connected to the display screen 110. It can be known that the control circuit board 120 can receive an external control signal and realize display control of the display screen 110 according to the external control signal.

[0043] The NFC coil 130 is used to receive or send a radio magnetic field signal. The NFC coil 130 is electrically connected to the control circuit board 120. It should be understood that the radio magnetic field signal received by the NFC coil 130 can be transmitted to the control circuit board 120, and converted by the control circuit board 120 into a control signal to control the display content of the display screen 110. The interactive signal between the control circuit board 120 and the external device can also be converted into a radio magnetic field signal and sent via the NFC coil 130.

[0044] The NFC coil 130 includes a first coil portion 131 and a second coil portion 132. It can be understood that the NFC coil 130 can be mainly composed of the first coil portion 131 and the second coil portion 132. Specifically, the first coil portion 131 is arranged on the display screen 110, and the second coil portion 132 is arranged on the control circuit board 120. At least two ends of the first coil portion 131 are electrically connected to at least two ends of the second coil portion 132 to form an NFC antenna structure, that is, to form an NFC coil to realize the electromagnetic induction function of the NFC coil. Among them, the first coil portion 131 can have two ends, and the second coil portion 132 can also have two ends. The first coil portion 131 and the second coil portion 132 are connected correspondingly at the two ends, thereby forming a complete NFC antenna structure.

[0045] The technical solution of the present application divides the NFC coil into a first coil portion 131 and a second coil portion 132, wherein the first coil portion 131 and the second coil portion 132 are respectively arranged on the display screen 110 and the control circuit board 120, thereby avoiding the NFC coil from being arranged in a separate area on the control circuit board, effectively reducing the occupied area of ​​the NFC coil on the control circuit board, thereby facilitating the layout of other components on the control circuit board, and when the NFC coil is respectively arranged on the display screen 110 and the control circuit board 120, the effective area of ​​the NFC coil can be effectively increased, thereby improving the convenience of using the NFC function of the display screen module.

[0046] Figure 2 It is a schematic diagram of the structure of a display screen in a display screen module shown in an embodiment of the present application.

[0047] See also Figure 2 In some embodiments, the display screen 110 includes a display layer 111 and a drive substrate 112. The display layer 111 has a display surface and a non-display surface. It should be understood that the display layer 111 displays the corresponding pattern or image content through the display surface. It can also be said that the display surface is the front of the display layer 111, and the non-display surface is the back of the display layer 111. The drive substrate 112 is arranged on the non-display surface of the display layer 111, that is, the drive substrate 112 is arranged on the back of the display layer 111. Specifically, when the display screen 110 is working, the display layer 111 is driven by the drive substrate 112, so as to realize the display of the display screen 110. Among them, the drive substrate 112 is provided with a binding area 1121, at least two ends of the first coil part 131 are located in the binding area 1121, the control circuit board 120 has a connection end 121, at least two ends of the second coil part are located in the connection end 121, and the connection end 121 is electrically connected to the binding area 1121, so that at least two ends of the first coil part 131 and at least two ends of the second coil part 132 are electrically connected correspondingly.

[0048] The binding area 1121 may be provided with gold fingers or pins, and the connection end 121 may be provided with a connection element, such as a power strip, correspondingly. The binding area 1121 is connected to the connection element on the connection end 121 by using the gold fingers or pins, thereby realizing electrical connection between the connection end 121 and the binding area 1121. In addition, the binding area 1121 may also be used to bind a driver chip.

[0049] Figure 3 It is another structural schematic diagram of the display screen in the display screen module shown in the embodiment of the present application.

[0050] See also Figure 3In some embodiments, the display screen 110 may further include a transparent substrate 113 disposed on the display surface of the display layer 111 , wherein the transparent substrate 113 is used to protect the display layer 111 , and the transparent substrate 113 may also be used to cooperate with the driving substrate 112 to realize display driving of the display layer 111 .

[0051] In some embodiments, the display layer 111 may include one of a liquid crystal layer and an electronic paper layer. That is, the display layer 111 may be a liquid crystal layer or an electronic paper layer. For example, the display layer 111 may be an electronic paper film. It should be understood that the display screen 110 may be a liquid crystal display screen or an electronic paper display screen.

[0052] In some embodiments, the driving substrate 112 may include one of a glass substrate, a PCB circuit board, and an FPC circuit board. That is, the driving substrate 112 may be a glass substrate, a PCB circuit board, or an FPC circuit board. Specifically, the driving substrate 112 may be a thin film transistor array substrate. Specifically, the first coil portion 131 may be disposed on the driving substrate 112 by evaporation, etching, spraying, pasting, or the like.

[0053] In some embodiments, the first coil portion 131 may be located on any side of the drive substrate 112. It should be understood that the drive substrate 112 has a side facing the display layer 111 and another side away from the display layer 111, and the first coil portion 131 may be located on any side of the drive substrate 112.

[0054] Figure 4 It is a schematic diagram of the structure of a driving substrate in a display screen module shown in an embodiment of the present application.

[0055] See also Figure 4 In some embodiments, the driving substrate 112 is provided with a driving area 1122 and a non-driving area 1123 wound around the driving area 1122. Specifically, the driving substrate 112 drives the display layer 111 to display a pattern or image through the driving area 1122. It can be understood that according to the driving area 1122 of the driving substrate 112, a display area for displaying a pattern or image is correspondingly formed on the display layer 111, wherein the driving area 1122 corresponds to the display area. The first coil portion 131 is arranged in the non-driving area 1123, thereby reducing the influence of the first coil portion 131 on the display of the display screen 110. In some specific embodiments, the first coil portion 131 is wound around the driving area 1122. That is to say, the first coil portion 131 can be located in the non-driving area 1123 and is distributed around the driving area 1122, so that the area of ​​the NFC coil 130 can cover the display screen, further increasing the effective area of ​​the NFC coil 130.

[0056] In some embodiments, the driving region 1122 may include four first corners (not shown in the figure) that are axially symmetrically distributed. It should be understood that the four first corners of the driving region that are axially symmetric are diagonally distributed, such that the driving region 1122 is a regular figure. At least two adjacent first corners are rounded corners. It can be understood that one end of the driving region may have two rounded corners, so that the display region of the display layer 111 correspondingly has at least two adjacent second corners (not shown in the figure). In this way, one end of the display region may have at least two rounded corners.

[0057] In some embodiments, all four first corners are rounded corners. In this way, the display region of the display layer 111 can have four corresponding second corners that are rounded corners. It can be known that the display region having four second corners that are all rounded corners can form a rounded rectangle structure. Compared with the traditional rectangular display structure, the display region in the present application can better adapt to the application requirements of the arc chamfer display region, and at the same time can greatly reduce the corner spacing between the display region and the product to which it is applied, thereby improving the screen-to-body ratio of the display region.

[0058] In some embodiments, the first coil portion 131 is distributed in at least three segmented continuous segments. It can be understood that the first coil portion 131 is divided into at least three continuous regions, and at least one straight coil is provided in each region. In this way, the first coil portion 131 semi-surrounds the driving region 1122. That is to say, the first coil portion 131 can be in a "冂" shape, so that the first coil portion 131 better adapts to the display screen 110 and reduces the influence of the first coil portion 131 on the overall display effect of the display screen 110.

[0059] In some embodiments, the control circuit board 120 is provided with a wiring region 122 for laying out components. Specifically, a driving circuit may be provided in the wiring region 122. The driving circuit may include an NFC control circuit and / or a display screen control circuit. The NFC driving circuit is used to control the NFC coil to implement the NFC function, and the display screen control circuit is used to control the display screen to implement the display function. The second coil portion 132 is wound around the wiring region 122. It can be known that the second coil portion 132 does not pass through the wiring region 122. In this way, it is beneficial to the layout of components in the wiring region 122 and effectively reduces the influence of the second coil portion 132 on the operation of the components in the wiring region 122.

[0060] Figure 5 It is an application schematic diagram of the display screen module shown in the embodiments of the present application.

[0061] See together Figure 5In some embodiments, the control circuit board 120 can be a flexible circuit board. It can be known that when the control circuit board 120 is a flexible circuit board, that is, the control circuit board 120 can be folded relative to the display screen 110, so that the display screen module of the present application can be folded. Furthermore, when the display screen module of the present application is applied to a display device with a display function, for example, when the display screen module of the present application is applied to an e-book device, the control circuit board 120 is folded relative to the display screen 110, so that the display device can perform NFC interaction with other devices on both its display surface and non-display surface, greatly improving the operational convenience of the display device when using the NFC function. Of course, the control circuit board 120 can also be electrically connected to the display screen through a flexible circuit board.

[0062] Corresponding to the aforementioned application function implementation device embodiment, the present application also provides a display device and corresponding embodiments.

[0063] The present application also provides a display device, comprising the display screen module described above in the present application.

[0064] The display device of this embodiment divides the NFC coil into a first coil portion 131 and a second coil portion 132, wherein the first coil portion 131 and the second coil portion 132 are respectively arranged on the display screen 110 and the control circuit board 120, thereby avoiding the NFC coil from being arranged in a separate area on the control circuit board, effectively reducing the occupied area of ​​the NFC coil on the control circuit board, thereby facilitating the layout of other components on the control circuit board, and when the NFC coil is respectively arranged on the display screen 110 and the control circuit board 120, the effective area of ​​the NFC coil can be effectively increased, thereby improving the convenience of using the NFC function of the display screen module.
