DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. And in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Unless otherwise defined, technical or scientific terms used in this invention shall have the same general meaning as those generally understood by persons skilled in the art in the art to which this invention pertains. Words such as "include" or "comprise" used in this invention mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0043] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present invention. The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0044] In the prior art, the method is often used as follows Figure 1 The streaming media rearview mirror shown is used to present the image behind the vehicle. The anti-glare screen 01 and the display screen 02 in the streaming media rearview mirror are often designed to be flush with the edges. Since the display screen 02 has more peripheral circuits, a wider black border 03 is often required to shield the circuits. It can be seen that the existing device has a technical problem of a wider overall border.

[0045] In view of this, embodiments of the present invention provide a display device and a rearview mirror for achieving a narrow frame.

[0046] like Figure 2 FIG. 1 is a schematic diagram of a structure of a display device provided by an embodiment of the present invention. Specifically, the display device includes:

[0047] A display module 1 and a mirror switching screen 2 located on a light-emitting surface side of the display module 1, wherein the orthographic projection of the display module 1 on the mirror switching screen 2 completely falls within the area where the mirror switching screen 2 is located; when a first electrical signal is applied to the mirror switching screen 2, the mirror switching screen 2 is in a mirror mode to implement a mirror function; and when a second electrical signal is applied to the mirror switching screen 2, the mirror switching screen 2 is in a light-transmitting mode to enable the display module 1 to display an image;

[0048] The side edge of the surface of the mirror switching screen 2 facing the display module 1 is provided with a first binding electrode 10 , and the side edge of the surface of the display module 1 facing the mirror switching screen 2 is provided with a second binding electrode 20 .

[0049] In an embodiment of the present invention, the mirror switching screen 2 can be a liquid crystal screen. When the first electrical signal is loaded on the mirror switching screen 2, the mirror switching screen 2 is in mirror mode to realize the mirror function. When the second electrical signal is loaded on the mirror switching screen 2, the mirror switching screen 2 is in transmittance mode to enable the display module 1 to display the picture. In this way, the mirror switching screen 2 realizes the compatibility of the streaming media display of the display device and the mirror rearview mirror, thereby ensuring the performance of the display device. In addition, the corresponding electrical signal can be loaded on the mirror switching screen 2 to reduce the intensity of the light reflected into the human eye, thereby avoiding glare damage to people and improving the safety performance of the display device.

[0050] In a specific implementation process, the mirror switching screen 2 may be a liquid crystal screen, and the display module 1 may be a liquid crystal display module. The mirror switching screen 2 may include a first substrate 11, a second substrate 12, and a liquid crystal layer located between the first substrate 11 and the second substrate 12. The display module 1 may include a third substrate 21, a fourth substrate 22, and a liquid crystal layer located between the third substrate 21 and the fourth substrate 22. Figure 2 Only the case where the mirror switching screen 2 and the display module 1 include two substrates is illustrated, and other functional film layers are not shown. Of course, in addition to the two substrates, the mirror switching screen 2 and the display module 1 may also include other functional film layers. The specific settings can be made by referring to relevant technologies, which will not be repeated here.

[0051] Combine Figure 2As shown, the orthographic projection of the display module 1 on the mirror switching screen 2 completely falls within the area where the mirror switching screen 2 is located, especially when the area where the mirror switching screen 2 is located is larger than the area where the orthographic projection of the display module 1 on the mirror switching screen 2 is located, since the peripheral circuits of the mirror switching screen 2 are often relatively small, a narrower frame can be set to block the peripheral circuits, thereby realizing a narrow frame design of the display device.

[0052] In addition, a first binding electrode 10 is provided on the side edge of the surface of the mirror switching screen 2 facing the display module 1, and a second binding electrode 20 is provided on the side edge of the display module 1 facing the mirror switching screen 2. In this way, it can be ensured that the surface of the mirror switching screen 2 facing away from the display module 1 has good flatness, and there is no need to additionally provide a cover plate on the surface of the mirror switching screen 2 facing away from the display module 1, thereby avoiding the influence of the cover plate on the reflectivity and transmittance of the display device, thereby taking into account the display quality. Moreover, the display device is more beautiful.

[0053] In the embodiment of the present invention, in order to effectively shield the first binding electrode 10, the shielding bar 13 for shielding the first binding electrode 10 can be set in the following two ways, but it is not limited to the following two setting ways. Those skilled in the art can also set the shielding bar 13 according to actual application needs. Figure 3 The figure shows one of the structural schematic diagrams of the display device corresponding to when the first setting method is used to set the shielding bar 13. Specifically, the shielding bar 13 is set on the side edge of the surface of the mirror switching screen 2 away from the display module 1, and the positive projection of the first binding electrode 10 on the mirror switching screen 2 completely falls within the area of ​​the shielding bar 13 on the mirror switching screen 2.

[0054] During the specific implementation process, since the shielding bar 13 is arranged on the side edge of the surface of the mirror switching screen 2 facing away from the display module 1, when the positive projection of the first binding electrode 10 set on the mirror switching screen 2 completely falls within the area of ​​the shielding bar 13 on the mirror switching screen 2, the shielding bar 13 can effectively shield the first binding electrode 10.

[0055] like Figure 4The figure shows one structural schematic diagram of a display device corresponding to the second configuration of the shielding strip 13. Specifically, the shielding strip 13 is provided on the side edge of the surface of the mirror switching screen 2 facing the display module 1, and the shielding strip 13 completely surrounds the first binding electrode 10. In actual production, the required shielding strip 13 can be formed simultaneously with the production of the electrode film layers of the mirror switching screen 2, thereby simplifying the display device production process and reducing production costs.

[0056] In the embodiment of the present invention, the first binding electrode 10 and the second binding electrode 20 can be arranged in the following two ways, but are limited to the following two ways. Those skilled in the art can also arrange the first binding electrode 10 and the second binding electrode 20 according to actual application needs. Figure 5 The figure shows one structural schematic diagram of the display device when the first binding electrode 10 and the second binding electrode 20 are arranged using the first arrangement. Specifically, the surface of the mirror switching screen 2 facing the display module 1 includes a first side 101 and a second side 102 that are oppositely arranged. The first binding electrode 10 is completely within the area of ​​the first side 101, and the second binding electrode 20 is completely within the area of ​​the second side 102. In other words, the first binding electrode 10 and the second binding electrode 20 are arranged on opposite sides.

[0057] like Figure 6 The figure shows one structural schematic diagram of the display device when the first binding electrode 10 and the second binding electrode 20 are arranged using the second arrangement. Specifically, the surface of the mirror switching screen 2 facing the display module 1 includes a first side 101 and a second side 102 that are oppositely arranged. The first binding electrode 10 is completely within the area of ​​the second side 102, and the second binding electrode 20 is completely within the area of ​​the second side 102. In other words, the first binding electrode 10 and the second binding electrode 20 are arranged on the same side, which can achieve a narrow-bezel design for the display device to a greater extent.

[0058] In an embodiment of the present invention, in order to improve the structural stability of the display device, as shown in FIG. Figure 7 The figure shows one of the structural schematic diagrams of the display device. Specifically, the orthographic projection of the display module 1 on the mirror switching screen 2 and the orthographic projection of the first binding electrode 10 on the mirror switching screen 2 do not overlap with each other. The display device also includes a back panel 3 facing away from the light-emitting surface of the display module 1 and a first support member 4 arranged on the back panel 3. The first support member 4 is in contact with the first binding electrode 10.

[0059] In the specific implementation process, Figure 7 As shown, the shielding strip 13 is arranged on the side edge of the surface of the mirror switching screen 2 away from the display panel, the first binding electrode 10 and the second binding electrode 20 are arranged on opposite sides, and the first supporting member 4 arranged on the back panel 3 away from the light-emitting surface of the display module 1 is in contact with the first binding electrode 10. The support of the mirror switching screen 2 is achieved through the first supporting member 4, thereby improving the structural stability of the display device.

[0060] During the specific implementation process, if Figure 7 The mirror switching screen 2 in the display device shown is in the light transmission mode. Accordingly, the display module 1 can display the picture. At this time, the display area A for displaying the picture and the non-display area B for setting the peripheral circuit of the display device can be divided into the following diagrams: Figure 8 If Figure 7 The mirror switching screen 2 of the display device shown is in the mirror mode. Accordingly, the division diagram of the mirror area a and the non-mirror area b of the display device can be as follows: Figure 9 shown.

[0061] In practical applications, we can also use Figure 10 The first support member 4 is set in the manner shown. Specifically, the shielding strip 13 is set on the side edge of the surface of the mirror switching screen 2 away from the display module 1, and the first binding electrode 10 and the second binding electrode 20 are set on the same side. The orthographic projection of the display module 1 on the mirror switching screen 2 and the orthographic projection of the first binding electrode 10 on the mirror switching screen 2 do not overlap with each other. The first support member 4 arranged on the back panel 3 on the side away from the light-emitting surface of the display module 1 is in contact with the first binding electrode 10. The support of the mirror switching screen 2 is achieved by the first support member 4, thereby improving the structural stability of the display device.

[0062] In an embodiment of the present invention, in order to improve the structural stability of the display device, as shown in FIG. Figure 11 The figure shows one of the structural schematic diagrams of the display device. Specifically, the orthographic projection of the display module 1 on the mirror switching screen 2 overlaps with the orthographic projection of the first binding electrode 10 on the mirror switching screen 2. The display device also includes a second support member 5 arranged on the display module 1, and the second support member 5 is located between the first binding electrode 10 and the second binding electrode 20.

[0063] In the specific implementation process, Figure 11As shown, the shielding bar 13 is arranged on the side edge of the surface of the mirror switching screen 2 facing the display module 1, the shielding bar 13 completely surrounds the first binding electrode 10, and the first binding electrode 10 and the second binding electrode 20 are arranged on the same side, and the second support member 5 arranged on the display module 1 is located between the first binding electrode 10 and the second binding electrode 20, and contacts the first binding electrode 10 and the second binding electrode 20 respectively. The display module 1 supports the mirror switching screen 2 through the second support member 5, thereby improving the structural stability of the display device.

[0064] During the specific implementation process, if Figure 11 The mirror switching screen 2 in the display device shown is in the light transmission mode. Accordingly, the display module 1 can display the picture. At this time, the display area A for displaying the picture and the non-display area B for setting the peripheral circuit of the display device can be divided into the following diagrams: Figure 12 If Figure 11 The mirror switching screen 2 of the display device shown is in the mirror mode. Accordingly, the division diagram of the mirror area a and the non-mirror area b of the display device can be as follows: Figure 13 shown.

[0065] In the specific implementation process, in addition to Figure 11 In addition to setting the second support member 5 in the manner shown, it is also possible to Figure 14 The second support member 5 is set in the manner shown. Specifically, the shielding bar 13 is set at the side edge of the surface of the mirror switching screen 2 facing the display module 1. The shielding bar 13 completely surrounds the first binding electrode 10, and the first binding electrode 10 and the second binding electrode 20 are set on the same side. The orthographic projection of the second binding electrode 20 on the mirror switching screen 2 and the orthographic projection of the first binding electrode 10 on the mirror switching screen 2 do not overlap with each other. The second support member 5 is set on the display module 1, and the second support member 5 is in contact with the surface of the mirror switching screen 2 facing the display module 1. The display module 1 supports the mirror switching screen 2 through the second support member 5, thereby improving the structural stability of the display device.

[0066] It should be noted that the shielding strip 13 used in the embodiment of the present invention can be black ink, which can effectively shield the peripheral circuits in the display device on the one hand, and effectively prevent peripheral light leakage on the other hand, thereby improving the performance of the display device. The first support member 4 and the second support member 5 can be black, which can effectively prevent light leakage while ensuring the supporting performance. In addition, in addition to improving the stability of the display device by using the first support member 4 and the second support member 5, Figure 15 As shown, the stability of the display device can also be improved by using a black plastic frame 6 provided on the back plate 3 of the display device.

[0067] In the embodiment of the present invention, Figure 16 The figure shows one structural schematic diagram of a display device, which also includes a flexible circuit board 7. The flexible circuit board 7 is coupled to the first binding electrode 10 through a pin or welding, and the flexible circuit board 7 is bent to the back of the display module 1 in a direction away from the mirror switching screen 2.

[0068] In the specific implementation process, the control signal of the mirror switching screen 2 can be a common electrode signal or a data signal. Figure 17 In the vertical bonding manner shown, the flexible circuit board 7 is coupled to the first bonding electrode 10 through a pin, so that the control signal from the mirror switching screen 2 is led out through the first bonding electrode 10 . Figure 7 The electrodes on the S1 surface shown in the figure are coupled to the first binding electrodes 10, and the electrodes on the S2 surface are coupled to the flexible circuit board 7 via ejector pins. In this way, the control signals from the mirror switching screen 2 can be led to the flexible circuit board 7 via the first binding electrodes 10. In addition, the flexible circuit board 7 is bent away from the mirror switching screen 2 to the back of the display module 1, further ensuring the narrow bezel design of the display device.

[0069] In the embodiment of the present invention, Figure 18 The figure shows a schematic diagram of one structure of a display device, which also includes a double-sided tape 8 that is at least partially filled into the cavity surrounded by the flexible circuit board 7 and the mirror switching screen 2. The double-sided tape 8 includes a main body 81 and an extension portion 82 extending from the main body 81 toward the center position of the mirror switching screen 2.

[0070] In the specific implementation process, combined with Figure 18As shown, after coupling the first binding electrode 10 with the flexible circuit board 7, the double-sided tape 8 can be coated around the periphery of the first binding electrode 10. In the process of bending the flexible circuit board 7 in the direction away from the mirror switching screen 2 to the back of the display module 1, the double-sided tape 8 can effectively avoid damage to the side edge of the mirror switching screen 2 due to excessive stress during the bending process. In this way, the double-sided tape 8 is at least partially filled into the cavity surrounded by the flexible circuit board 7 and the mirror switching screen 2. In addition, the double-sided tape 8 includes a main body 81 and an extension 82 extending from the main body 81 to the center of the mirror switching screen 2. On the one hand, the flatness of the surface of the mirror switching screen 2 away from the display module 1 is ensured by the main body 81 and the extension 82. On the other hand, the mirror switching screen 2 and the display module 1 are pasted together to ensure the stability of the overall structure. In addition, still combined with Figure 18 As shown, a layer of optically clear adhesive (OCA) 30 may be provided between the mirror switching screen 2 and the display module 1. Of course, no film layer may be provided between the mirror switching screen 2 and the display module 1. Specifically, it may be provided according to actual application requirements and is not limited here.

[0071] Based on the same inventive concept, Figure 19 As shown, an embodiment of the present invention further provides a rearview mirror, which includes a shell 9 and a display device 100 as described above, which is arranged in the shell 9. The principle of solving the problem by the rearview mirror is similar to that of the aforementioned display device 100. Therefore, the implementation of the display device 100 can refer to the implementation of the aforementioned display device 100, and the repeated parts will not be repeated.

[0072] In a specific implementation process, the rearview mirror provided in the embodiment of the present invention can be a vehicle-mounted rearview mirror. Other essential components of the rearview mirror should be understood by ordinary technicians in this field and will not be described in detail here, nor should they be used as limitations to the present invention.

[0073] An embodiment of the present invention provides a display device and a rearview mirror, wherein the display device includes a display module 1 and a mirror switching screen 2 located on the light-emitting side of the display module 1, and the orthographic projection of the display module 1 on the mirror switching screen 2 completely falls within the area where the mirror switching screen 2 is located. Especially when the area of ​​the mirror switching screen 2 is larger than the area of ​​the display module 1, since the peripheral circuits of the mirror switching screen 2 are often relatively small, a narrower frame can be set to block the peripheral circuits, thereby realizing a narrow frame design of the display device. In addition, a first binding electrode 10 is provided on the side edge of the surface of the mirror switching screen 2 facing the display module 1, and a second binding electrode 20 is provided on the side edge of the surface of the display module 1 facing the mirror switching screen 2, which can ensure that the surface of the mirror switching screen 2 facing away from the display module 1 has good flatness, and no additional cover plate is required, thereby taking into account the display quality.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
