[0034] In the related art, when an electronic paper module has an application requirement of an arc-chamfered display area, the appearance of the applied product needs to be designed accordingly to match the rectangular structure of the electronic paper module, which brings inconvenience to the application of the electronic paper module. In addition, due to the right angles of the rectangular structure of the electronic paper module, there is a large gap between the display screen formed by the electronic paper module and the edge of the arc structure in the applied product, resulting in a small screen-to-body ratio of the product, affecting the display effect of the product.
[0035] In response to the above problems, the embodiments of the present application provide an electronic paper display module that can directly adapt to the application requirements of the arc-chamfered display area, improve the convenience of using the electronic paper module, increase the screen-to-body ratio of the product, and thereby improve the display effect of the product.
[0036] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0037] Figure 1 It is a structural schematic diagram of the electronic paper display module shown in an embodiment of the present application.
[0038] See also Figure 1 The electronic paper display module of the present application includes: an electronic paper display layer 110 and a driving backplane 120. The electronic paper display layer 110 and the driving backplane 120 can be electrically connected by conductive adhesive.
[0039] The electronic paper display layer 110 has a display area 111 for displaying patterns. Among them, the electronic paper display layer 110 can be composed of an electronic paper film. The driving backplane 120 is attached to a surface of the electronic paper display layer 110. The driving backplane 120 is provided with a driving area (not shown in the figure), and the driving area is used to drive the display area 111 to display patterns. Among them, the driving area corresponds to the display area 111 of the electronic paper display layer 110. It can be understood that when the electronic paper display module of the present application is working, the display area 111 on the electronic paper display layer 110 is driven by the driving area of the driving backplane 120, so that the electronic paper display layer 110 displays patterns in the display area 111. It should be noted that the area of the driving backplane 120 can be larger than the electronic paper display layer 110, so that the driving backplane 120 can fully cover the electronic paper display layer 110 and improve the working stability of the electronic paper display layer 110.
[0040] The driving region may include four first corners (not shown) that are axially symmetrically distributed. It should be understood that the four first corners of the driving region that are axially symmetrical are diagonally distributed, so that the driving region is a regular pattern. At least two adjacent first corners are rounded, and it can be understood that one side end of the driving region may have two rounded corners, so that the display region 111 has at least two adjacent second corners 1111 correspondingly, and thus one side end of the display region 111 may have at least two rounded corners.
[0041] In some embodiments, the four first corners are all rounded, so that the display area 111 can have four corresponding rounded second corners 1111. It can be seen that the display area 111 has four rounded second corners 1111, which can form a rounded rectangular structure. Compared with the traditional rectangular display structure, the display area 111 in the present application can be more suitable for the application requirements of the arc chamfered display area, and can greatly reduce the corner distance between the display area and the applied product, thereby improving the screen-to-body ratio of the display area.
[0042] Figure 2 It is another structural schematic diagram of the electronic paper display module shown in the embodiment of the present application.
[0043] See also Figure 2In some embodiments, the electronic paper display layer 110 has at least two adjacent third corners 112 with rounded corners, and the driving backplane 120 has at least two adjacent fourth corners 121 with rounded corners, and at least two adjacent third corners 112 correspond one-to-one with at least two adjacent fourth corners 121. It can be known that at least two adjacent third corners 112 with rounded corners make one end of the electronic paper display layer 110 have two rounded corners, and at least two adjacent fourth corners 121 with rounded corners make one end of the driving backplane have two rounded corners. The third corner 112 corresponds one-to-one with the fourth corner 121, so that one end of the electronic paper display module can adapt to the application requirements of the arc chamfered display area, thereby effectively reducing the distance between the electronic paper display module and the edge of the applied product. In this way, more area can be reserved for the display area on the electronic paper display module, which is convenient for subsequently improving the screen-to-body ratio of the electronic paper display module.
[0044] In some embodiments, at least two adjacent third corners 112 and at least two adjacent fourth corners 121 correspond to the same at least two adjacent second corners 1111. That is, the electronic paper display layer 110, the driving backplane 120 and the display area 111 have two corresponding rounded corners at least at the same end, so that one end of the electronic paper display module can greatly reduce the edge spacing between the applied product, and at the same time, the display effect of the micro-frame can be achieved by reducing the edge spacing between the display area 111 and the applied product.
[0045] In some embodiments, the electronic paper display layer 110 has four adjacent third corners 112 with rounded corners, the driving backplane 120 has four adjacent fourth corners with rounded corners, and the four second corners, the four third corners, and the four fourth corners correspond to each other. In the above structure, it can be known that the shape of the electronic paper display layer 110, the shape of the driving backplane 120, and the display area 111 can all be corresponding rounded rectangles, so that the electronic paper display module of the present application can be adapted to products with rounded rectangular structures, such as mobile phone cases and other products. The electronic paper display module has higher adaptability to products with rounded rectangular structures, which can effectively improve the display effect and aesthetics of the electronic paper display module in the applied products.
[0046] In some embodiments, the driver backplane 120 is further provided with a binding area 122 for binding a chip, wherein the binding area 122 can be used to bind a driver chip. Specifically, the binding area 122 can be located on one side of the driver area. It can be understood that the binding area can also be used to bind an FPC, and the electronic paper display module of the present application can be transmitted with external signals through the FPC.
[0047] In this embodiment, the technical solution of the present application provides at least two adjacent and rounded first corners on the driving area, so that the display area 111 of the electronic paper display module correspondingly has at least two adjacent and rounded second corners. In this way, when the electronic paper display module of the present application is applied, it is possible to directly adapt to the application requirements of the arc-chamfered display area without having to design the appearance of the applied product to adapt to the rectangular display structure, thereby improving the convenience of applying the electronic paper module and effectively shortening the distance between at least one side end of the display area of the electronic paper module and the edge of the arc structure in the applied product, thereby improving the screen-to-body ratio of the product and further improving the display effect of the product.
[0048] Corresponding to the aforementioned electronic display module embodiment, the present application also provides a mobile phone case and corresponding embodiments.
[0049] Figure 3 It is a schematic diagram of the structure of a mobile phone case shown in an embodiment of the present application.
[0050] See also Figures 1 to 3 The mobile phone case of the present application includes: a housing 200 and the electronic paper display module 100 in the aforementioned embodiment of the present application.
[0051] The bottom of the housing 200 has at least two adjacent fifth corners 210 with rounded corners, the electronic paper display module 100 is arranged on the housing 200, and the display area 111 of the electronic paper display module 100 is displayed through the back of the housing. In other words, the back of the housing 200 of the mobile phone case can realize pattern display through the electronic paper display module 100. Among them, at least two adjacent second corners 1111 of the display area 111 correspond to at least two adjacent fifth corners 210.
[0052] Through the above structure, at least one end of the display area 111 of the electronic paper display module 100 can be adapted to one end of the shell 200 of the mobile phone case. Taking the bottom end of the mobile phone case (i.e., the end away from the mobile phone camera) as an example, the bottom end of the mobile phone case has two rounded corners, and the display area 111 of the electronic paper display module 100 has two rounded corners accordingly. In this way, the display area 111 of the electronic paper display module 100 can be adapted to the mobile phone case with two rounded corners at the bottom, thereby effectively shortening the distance between at least one side end of the display area 111 of the electronic paper module and the edge of the arc structure in the mobile phone case (i.e., the bottom part of the mobile phone case), thereby improving the screen-to-body ratio of the electronic paper display module on the mobile phone case, and thereby improving the display effect of the product.
[0053] In some embodiments, the housing 200 may also be provided with a clearance groove 220 corresponding to the mobile phone camera, wherein the electronic paper display module 100 may be correspondingly arranged in a clearance area corresponding to the clearance groove 220 to avoid blocking the mobile phone camera.
[0054] In some embodiments, the housing 200 may be made of silicone.
[0055] In some embodiments, the mobile phone case also includes a transparent protective layer (not shown in the figure) covering the back of the shell 200 or the display area 111 of the electronic paper display module 100. The transparent protective layer can be made of glass or acrylic material. The transparent protective layer is used to protect the electronic display module, thereby effectively improving the service life of the product.
[0056] Figure 4 It is another structural schematic diagram of the mobile phone case shown in the embodiment of the present application.
[0057] See also Figure 4 In some embodiments, the housing 200 has four fifth corners 210, all of which are rounded. It can be understood that the housing 200 can be a rounded rectangular structure. The four second corners 1111 of the display area 111 correspond one to one with the four fifth corners 210. Through the above structure, the display area 111 can form a rounded rectangular structure, so that the display area 111 in the electronic paper display module 100 can be more suitable for the application requirements of the housing 200 with a rounded rectangular structure, and at the same time, the distance between the display area 111 as a whole and the edge of the housing 200 can be greatly reduced, thereby improving the screen ratio of the display area 111.
[0058] In some specific embodiments, the distance from the edge of the electronic paper display layer 110 to the edge of the housing 200 is slightly smaller than the distance from the driving area to the edge of the housing 200. It can be understood that the area of the driving backplane 120 covers the electronic paper display layer 110, and the driving area corresponds to the display area 111 of the electronic paper display layer 110. The distance from the edge of the electronic paper display layer 110 to the edge of the housing 200 is designed to be slightly smaller than the distance from the driving area to the edge of the housing 200, which can maximize the display range of the entire electronic paper display module and enhance the micro-frame effect between at least three sides of the entire electronic paper display module 100 and at least three sides of the housing 200.
[0059] In some other embodiments, the mobile phone case may also include: an NFC module (not shown in the figure) electrically connected to the driving backplane 120. Among them, the NFC module is used to drive the backplane 120 to supply power, so that the driving backplane 120 drives the display area 111 of the electronic paper display layer 110 to display a pattern. In other words, the electronic paper display module 100 in the present application can be powered by the NFC module, eliminating the traditional power supply method using a power supply, and further improving the convenience of using the mobile phone case of the present application. It should be noted that the NFC module can also use the NFC signal to control the pattern displayed in the display area 111 of the electronic paper display layer 110, that is, the NFC signal sent by the mobile phone or other device is received by the NFC module, and then the pattern displayed in the display area 111 is controlled by the driving backplane 120.
[0060] In this embodiment, the technical solution of the present application is to set an electronic paper display module on the shell of the mobile phone case, wherein at least two adjacent and rounded first corners are set on the driving area of the electronic paper display module, so that the display area 111 of the electronic paper display module correspondingly has at least two adjacent and rounded second corners. In this way, when the electronic paper display module of the present application is applied, it is possible to directly adapt to the application requirements of the arc-chamfered display area on the shell of the mobile phone case, and there is no need to design the shell of the mobile phone case to adapt to the appearance of the rectangular display structure, thereby improving the convenience of applying the electronic paper module. At the same time, it can effectively shorten the distance between at least one side end of the display area of the electronic paper module and the edge of the arc structure on the shell of the mobile phone case, thereby improving the screen-to-body ratio of the product, and further improving the display effect of the product.
