Thus, embodiments of the present application have been described herein with reference to particular embodiments. Other embodiments will be apparent to those of ordinary skill in the art upon reviewing the description. It is therefore intended to include all such embodiments as fall within the scope of the appended claims. Moreover, although exemplary embodiments have been described in some detail, those skilled in the art will appreciate that various modifications are possible that do not depart from the spirit and scope of the present embodiments. Accordingly, it is intended that all such variations be included within the scope of the present embodiments as described herein.

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings.

[0039] The display device of the embodiments of the present application can be applied to various electronic devices, and is particularly suitable for 3C electronic products such as computers and peripherals, communications, and consumer electronics, for example, smart phones, notebook computers, tablet computers, smart wearable devices, home appliances, game devices, and the like. In addition, the display device can also be applied to other types of electronic devices such as automotive electronics. The display device includes a display screen.

[0040] By way of example and not limitation, the display screen of the embodiments of the present application can be used to display information input by a user or information provided to a user, as well as various graphical user interfaces of an electronic device, which can be composed of images, text, icons, video, and any combination thereof.

[0041] By way of example and not limitation, the display screen can be a display screen with self-luminous units, such as an organic light-emitting diode (OLED) display screen or a micro-LED display screen. The display screen can also be a non-self-luminous display screen, such as a liquid crystal display screen or other passive light-emitting display screen.

[0042] By way of example and not limitation, the optical detection module of the embodiments of the present application can be used in an optical signal detection system, such as ambient light detection, to automatically adjust the keyboard light, screen brightness, etc., and infrared light detection, to automatically sense objects, etc. The optical sensing device of the embodiments of the present application can also be used in an optical imaging system, such as image signal recognition, and can also be used in an optical recognition system, such as optical fingerprint recognition, etc.

[0043] For the optical detection module arranged under the display screen, some light signals other than the target signals can be filtered out by arranging the optical filter. However, the adjustment of the optical path structure cannot shield electromagnetic interference, and the electromagnetic waves from the environment and the display screen can be received by the optical detection module together with the light signals, resulting in high noise of the optical detection module, low signal-to-noise ratio, and serious impact on the performance of the optical detection module and user experience.

[0044] Therefore, the embodiments of the present application provide a display device which can effectively improve the signal-to-noise ratio of the under-screen optical detection module and improve user experience.

[0045] Figure 1 FIG. 1 is a schematic structural diagram of a display device according to an embodiment of the present application. As shown in FIG. 1, the display device 100 includes a display screen 101, an optical detection module 102, and a transparent conductive film 103. Figure 1

[0046] The optical detection module 102 is arranged under the display screen 101, and the receiving end 1021 of the optical detection module 102 is used to receive incident light signals. The transparent conductive film 103 is arranged between the receiving end 1021 and the display screen 101, and is connected to the ground end of the display device 100.

[0047] The transparent conductive film 103 can be used to couple electromagnetic waves from the environment and the display screen 101, and transmit the electromagnetic waves to the ground end of the display device 100. It should be noted that Figure 1 The ground end of the display device 100 is not shown in FIG. 1.

[0048] ​Therefore, in the display device 100 provided by the embodiment of the present application, the transparent conductive film 103 is arranged between the receiving end 1021 of the optical detection module 102 and the display screen 101, and the transparent conductive film 103 is connected to the ground end of the display device 100. When the electromagnetic wave is transmitted to the transparent conductive film 103, the electromagnetic wave is coupled with the transparent conductive film 103, and the electromagnetic coupling noise generated is eliminated through the ground end of the display device 100, while the optical signal is received by the receiving end 1021 of the optical detection module 102 through the transparent conductive film 103. Therefore, without changing the original structure of the optical detection module 102, the electromagnetic interference from the environment and the display screen is effectively shielded, the signal-to-noise ratio is improved, and thus the performance of the optical detection module 102 is improved, and the user experience of the display device is improved.

[0049] Figure 2 A schematic structural diagram of another display device 200 provided by the embodiment of the present application is shown.

[0050] As shown in Figure 2 , optionally, the optical detection module 102 further includes a transmitting end 1022, and the transmitting end 1022 is configured to transmit an optical signal. Specifically, the scheme of the present application is applicable to the optical detection module 102 including only the receiving end 1021, and is also applicable to the optical detection module 102 including both the transmitting end 1022 and the receiving end 1021.

[0051] Please continue to refer to Figure 1 and Figure 2 , optionally, the display device 100 and the display device 200 further include a support 104, and the support 104 is configured to support the display screen 101.

[0052] Optionally, as shown in Figure 1 and Figure 2 , the display screen 101 includes a cover plate 1011, a display layer 1012, and a conductive member 1013. The conductive member 1013 is configured to be electrically connected to other structures in the display device 100. It can also be connected to the ground end of the display device 100. The cover plate 1011 can be a glass cover plate or a sapphire cover plate, which is located above the display screen 101 and covers the front surface of the display screen 101. The display layer 1012 can be an OLED layer or a Micro-LED layer.

[0053] In the thickness direction x of the display screen 101, the support 104 and the conductive member 1013 are both provided with an opening at a position corresponding to the optical detection module 102, so that the optical signal can be emitted or received by the optical detection module 102.

[0054] As shown in Figure 1As shown in FIG. 1, the conductive member 1013 can include one or more apertures. The support member 104 can also include one or more apertures. As shown in FIG. 1, in the case where the optical detection module 102 only includes the receiving end 1021, the conductive member 1013 can include only one aperture, and the support member 104 can also include only one aperture. As shown in FIG. 1, in the case where the optical detection module 102 includes both the transmitting end 1022 and the receiving end 1021, the conductive member 1013 can be provided with one aperture at the corresponding position of the transmitting end 1022 and one aperture at the corresponding position of the receiving end 1021, and the support member 104 can also be provided with one aperture at the corresponding position of the transmitting end 1022 and one aperture at the corresponding position of the receiving end 1021. Figure 2

[0055] Optionally, the shape and size of the aperture of the conductive member 1013 can be selected according to the receiving angle and the transmitting angle of the optical detection module 102. Figure 3 Figure 4 As shown in FIG. 1, the conductive member 1013 is shown in a partial schematic view. As shown in FIG. 1, in one example, the aperture of the conductive member 1013 is a square aperture. As shown in FIG. 1, in another example, the aperture of the conductive member 1013 is a circular aperture. Figure 3 Figure 4

[0056] Optionally, in the thickness direction x of the display screen 101, the projection of the transparent conductive film 103 covers the receiving end 1021.

[0057] Specifically, the projection of the transparent conductive film 103 in the thickness direction x of the display screen 101 covers the receiving end 1021, so that the light signals that can be received by the receiving end 1021 are all light signals after shielding electromagnetic interference. It should be noted that in the actual production process, due to the process limitation, the projection of the transparent conductive film 103 in the thickness direction x of the display screen 101 can not completely cover the receiving end 1021, but can leave a certain gap.

[0058] Optionally, the size and number of the apertures of the support member 104 can also be designed according to the structure of the optical detection module 102. Figure 5 Figure 6 As shown in FIG. 1, the support member 104 is shown in a partial schematic view. As shown in FIG. 1, in one example, the support member 104 can include two apertures. One aperture corresponds to the receiving end 1021, and the aperture is completely covered by the transparent conductive film 103. The other aperture corresponds to the transmitting end 1022, and the aperture is not covered by the transparent conductive film 103. Figure 5 Figure 6 In FIG. 1, the thickness direction x of the display screen 101 is the direction perpendicular to the paper surface.

[0059] As shown in FIG. 1, in one example, in the case where the optical detection module 102 includes both the transmitting end 1022 and the receiving end 1021, the support member 104 can include two apertures. One aperture corresponds to the receiving end 1021, and the aperture is completely covered by the transparent conductive film 103. The other aperture corresponds to the transmitting end 1022, and the aperture is not covered by the transparent conductive film 103. Figure 5 Figure 6 ​​​​​​​As shown, in another example, where the optical detection module 102 includes both a transmitter 1022 and a receiver 1021, the support member 104 may also include only one opening, which corresponds to both the transmitter 1022 and the receiver 1021. In this case, the transparent conductive film 103 only covers part of the opening.

[0060] The following, combined with Figures 7 to 12 This paper describes the connection method between the transparent conductive film 103 and the ground terminal in the embodiments of this application.

[0061] Figure 7 This is a schematic structural diagram of a display device 300 according to this application.

[0062] like Figure 7 As shown, the optical detection module 102 in the display device 300 includes both a transmitter 1022 and a receiver 1021. The support member 104 has openings at the corresponding positions of the transmitter 1022 and the receiver 1021, and at least part of the support member 104 extends between the optical detection module 102 and the display screen 101.

[0063] Optionally, such as Figure 7 As shown, the transparent conductive film 103 is connected to the support member 104, and the support member 104 is connected to the grounding terminal of the display device 300.

[0064] Specifically, the support member 104 is a frame structure for supporting the display screen 101. The optical detection module 102 can be disposed within the receiving space of the support member 104. Thus, at least a portion of the support member 104 is located between the optical detection module 102 and the display screen 101. By disposing a transparent conductive film 103 on the support member, the transparent conductive film 103 is positioned between the optical detection module 102 and the display screen 101. The support member 104 is typically made of metal or alloy and can be electrically connected to the ground terminal of the display device 300. Therefore, by connecting the transparent conductive film 103 to the support member 104, an electrical connection can be achieved between the transparent conductive film 103 and the ground terminal of the display device 300.

[0065] Alternatively, the electrical connection between the transparent conductive film 103 and other components can be achieved by pasting with an adhesive conductive material, or by other methods such as welding.

[0066] Optionally, such as Figure 7 As shown, the transparent conductive film 103 is attached to the support member 104 by the conductive adhesive 105, and then electrically connected to the grounding terminal of the display device 300 through the support member 104.

[0067] In the embodiments of the present application, the transparent conductive film 103 is connected with the support by means of the conductive adhesive 105, and the connection method is simple and easy to implement, which is helpful for the automation of the display device and helps to improve the production efficiency of the display device.

[0068] Optionally, the support 104 comprises an electrically connected area for bonding with the conductive adhesive 105. The electrically connected area is a surface treated area. For example, the surface treatment comprises nickel plating, iron plating, etc.

[0069] Specifically, the support 104 can be surface treated at the bonding area of the support 104 and the conductive adhesive 105 to improve the electrical conductivity of the area, thereby improving the electrical connection reliability of the conductive adhesive 105 and the support 104.

[0070] Optionally, as shown in Figure 7 The display device 300 further comprises a main board 106, which is arranged below the optical detection module 102. Specifically, the main board 106 is a circuit board for controlling the display device 300. The main board 106 can be a ceramic circuit board, a PCB (Printed Circuit Board), an FPC (Flexible Printed Circuit board), etc., and the embodiments of the present application are not limited thereto. In one example, the main board 106 can be provided with a grounding member, which serves as a grounding end of the display device 300. In another example, the main board 106 can also be connected with the grounding end of the display device 300.

[0071] Optionally, as shown in Figure 7 The display device 300 further comprises a small board 1023 connected with the main board 106 and capable of data transmission with the main board 106. The small board 1023 is a circuit board arranged to change the height of the optical detection module 102 in the display device 300, which can be connected with the optical detection module 102 for controlling the optical detection module 102. Specifically, the small board 1023 can be a PCB, an NPC (Nested Piezo-composite Circuit) board, etc., but the embodiments of the present application are not limited thereto. In some examples, the small board 1023 can be produced integrally with the optical detection module 102 to form an integral whole; in other examples, the small board 1023 can also exist independently.

[0072] Optionally, as shown in Figure 7 The blocking member 107 is arranged between the transmitting end 1022 and the receiving end 1021 to block the optical signal emitted by the transmitting end 1022 from crosstalk to the receiving end 1021. Specifically, the blocking member 107 can be a black foam or other material capable of blocking optical signals. In one example, as shown in Figure 5 andFigure 6 As shown, the blocking member 107 can be arranged around the emitting end 1022 to improve the blocking effect on the light signal emitted by the emitting end 1022.

[0073] Optionally, the blocking member 107 is arranged on the support member 104.

[0074] Specifically, Figure 7 As shown, the support member 104 is provided with openings at the emitting end 1022 and the receiving end 1021 respectively, and thus there is a part of the support member 104 between the emitting end 1022 and the receiving end 1021. The blocking member 107 can be arranged on the support member 104 to prevent light crosstalk between the emitting end 1022 and the receiving end 1021.

[0075] Please continue to see Figure 7 Optionally, the transparent conductive film 103 includes a transparent substrate 1031 and a conductive layer 1032 arranged on at least one side of the transparent substrate 1031. It should be noted that, Figure 7 Only the case of arranging the conductive layer 1032 on one side of the transparent substrate 1031 is shown. In other examples, the conductive layer 1032 can be arranged on both sides of the transparent substrate 1031. The connection of the transparent conductive film 103 with other components in the embodiments of the present application refers to the connection of the conductive layer 1032 of the transparent conductive film 103 with other components.

[0076] Optionally, the conductive layer 1032 includes at least one of Indium Tin Oxide (ITO), F-doped Tin Oxide (FTO), and nano-silver.

[0077] Optionally, the transparent substrate 1031 includes at least one of glass, Poly Ethylene glycol Terephthalate (PET), or other transparent substrates.

[0078] Optionally, the transmittance of the transparent conductive film 103 to the incident light signal is greater than or equal to 95%. That is, the transparent conductive film 103 has a high light transmittance, which can reduce the attenuation of the incident light signal.

[0079] In the embodiments of the present application, by using the transparent conductive film 103 of the transparent substrate combined with ITO or silver oxide, high light transmittance and good conductivity can be achieved.

[0080] Optionally, the conductive layer 1032 can be prepared on the transparent substrate 1031 by magnetron sputtering, spin coating, spraying, dip coating, etc. However, the embodiments of the present application are not limited thereto.

[0081] Figure 8FIG. 4 is a schematic structural diagram of a display device 400 according to an embodiment of the present application.

[0082] Figure 8 In the illustrated embodiment, the transparent conductive film 103 is also connected with the support 104. Compared with the display device 300 in Figure 7 The support 104 in the display device 400 has only one opening corresponding to the optical detection module 102, which corresponds to both the emitting end 1022 and the receiving end 1021 of the optical detection module 102. The support 104 is located between the display screen 101 and the main board 106. By arranging the transparent conductive film 103 on the support 104, the transparent conductive film 103 can also be located between the optical detection module 102 and the display screen 101, and can be electrically connected to the ground of the display device 400 through the support 104.

[0083] Optionally, the blocking member 107 is arranged on the optical detection module 102.

[0084] Specifically, Figure 8 The support 104 has only one opening, and the optical detection module 102 is no longer partially supported by the support 104. The blocking member 107 can be arranged directly on the optical detection module 102 to prevent light interference between the emitting end 1022 and the receiving end 1021.

[0085] Figure 9 FIG. 5 is a schematic structural diagram of a display device 500 according to an embodiment of the present application.

[0086] Optionally, as Figure 9 The transparent conductive film 103 can be connected with the conductive member 1013, and the conductive member 1013 is connected with the ground of the display device 500.

[0087] Specifically, the conductive member 1013 of the display screen 101 can be a metal member such as a copper foil that can conduct electricity, and is arranged on the side of the display screen 101 facing the optical detection module 102. By arranging the transparent conductive film 103 below the conductive member 1013, the transparent conductive film 103 can be located between the optical detection module 102 and the display screen 101, and can be electrically connected to the ground of the display device 500 through the conductive member 1013.

[0088] Figure 9 In the illustrated embodiment, the support 104 has a structure similar to that of the embodiment in Figure 7 The support 104 has openings at the emitting end 1022 and the receiving end 1021, and there is part of the support 104 between the emitting end 1022 and the receiving end 1021. Thus, in Figure 9In the embodiment shown, the blocking member 107 can be arranged on the support member 104 to prevent light crosstalk between the emitting end 1022 and the receiving end 1021.

[0089] Figure 10 FIG. 6 is a schematic structural diagram of a display device 600 according to the present application.

[0090] Figure 10 In the embodiment shown, the transparent conductive film 103 is also connected to the conductive member 1013. Compared with the display device 500 in Figure 9 The support member 104 in the display device 600 has only one opening corresponding to the optical detection module 102, which corresponds to both the emitting end 1022 and the receiving end 1021 of the optical detection module 102. The support member 104 is located between the display screen 101 and the main board 106.
