Technical Field

[0002] The present application relates to the field of optical sensing technology, and more particularly, to a display device and an electronic device. Background Art

[0003] As mobile communication devices evolve toward full-screen displays, higher performance requirements are being placed on under-screen optical detection modules. On the one hand, the transmittance of display screens is decreasing, impacting the performance of optical detection modules. On the other hand, under-screen optical detection modules are susceptible to electromagnetic noise from the environment and the display, resulting in higher operating noise levels and impacting performance.

However, as the transmittance of display screens decreases, this significantly increases design difficulty and manufacturing costs. Therefore, improving the signal-to-noise ratio of optical inspection modules in display devices has become a pressing technical challenge.

[0038] It should be understood that the terms used in the embodiments of the present application and the appended claims are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present application. For example, the singular forms "a," "above," and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0039] It should be understood that “one embodiment” or “an embodiment” mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, “in one embodiment” or “in an embodiment” appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It should be understood that in the various embodiments of the present application, the size of the sequence numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0040] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0041] The display device of the embodiment of the present application can be applied to various electronic devices, especially 3C electronic products such as computers and their peripherals, communications, and consumer electronics, such as smartphones, laptops, tablets, smart wearable devices, home appliances, gaming devices, etc. 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.

[0042] As an example and not a limitation, the display screen of the embodiment of the present application can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device, which can be composed of images, text, icons, videos and any combination thereof.

[0043] By way of example and not limitation, the display screen may be a display screen having self-luminous elements, such as an organic light-emitting diode (OLED) display screen or a micro-LED display screen. The display screen may also be a non-self-luminous display screen, such as a liquid crystal display screen or other passively luminous display screen.

[0044] By way of example and not limitation, the optical detection module of the embodiments of the present application can be used in optical signal detection systems, such as ambient light detection, which can automatically adjust keyboard lights and screen brightness, and infrared light detection, which can automatically sense objects. The optical sensing device of the embodiments of the present application can also be used in optical imaging systems, such as for image signal recognition, and can also be used in optical recognition systems, such as optical fingerprint recognition.

[0045] For optical detection modules installed under displays, filters can be used to remove some light signals other than the target signal. However, adjusting the optical path structure cannot shield against electromagnetic interference. Electromagnetic waves from the environment and the display are received by the optical detection module along with the light signal, resulting in high noise and low signal-to-noise ratio, seriously affecting the performance of the optical detection module and the user experience.

[0046] In view of this, an embodiment of the present application provides a display device that can effectively improve the signal-to-noise ratio of the under-screen optical detection module and enhance the user experience.

[0047] FIG1 is a schematic structural diagram of a display device according to an embodiment of the present application. As shown in FIG1 , the display device 100 includes a display screen 101 , an optical detection module 102 , and a transparent conductive film 103 .

[0048] The optical detection module 102 is disposed 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 disposed between the receiving end 1021 and the display screen 101 and connected to the ground end of the display device 100 .

[0049] 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 terminal of the display device 100. It should be noted that the ground terminal of the display device 100 is not shown in FIG1 .

[0050] Therefore, in the display device 100 of the embodiment of the present application, a transparent conductive film 103 is set 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, so that when the electromagnetic wave is transmitted to the transparent conductive film 103, it is coupled with the transparent conductive film 103, and the generated electromagnetic coupling noise is eliminated by the ground end of the display device 100, and the light signal passes through the transparent conductive film 103 and is received by the receiving end 1021 of the optical detection module 102. 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, and its signal-to-noise ratio is improved, thereby improving the performance of the optical detection module 102 and improving the user experience of the display device.

[0051] FIG2 shows a schematic structural diagram of another display device 200 of the present application.

[0052] As shown in Figure 2, the optical detection module 102 optionally further includes a transmitter 1022 for transmitting optical signals. Specifically, the solution of the present application is applicable to an optical detection module 102 that includes only a receiver 1021, and is also applicable to an optical detection module 102 that includes both a transmitter 1022 and a receiver 1021.

[0053] Continuing to refer to FIG. 1 and FIG. 2 , optionally, the display device 100 and the display device 200 further include a support member 104 , and the support member 104 is used to support the display screen 101 .

[0054] Optionally, as shown in Figures 1 and 2, display screen 101 includes a cover plate 1011, a display layer 1012, and a conductive member 1013. Conductive member 1013 is used to electrically connect to other structures in display device 100. It can also be connected to the ground terminal of display device 100. Cover plate 1011 can be a glass cover plate or a sapphire cover plate, which is located above display screen 101 and covers the front surface of display screen 101. Display layer 1012 can be an OLED layer or a Micro-LED layer.

[0055] In the thickness direction x of the display screen 101 , the support member 104 and the conductive member 1013 are both provided with openings at positions corresponding to the optical detection module 102 , so as to enable light signals to be emitted or received by the optical detection module 102 .

[0056] As shown in FIG1 , when the optical detection module 102 includes only a receiving end 1021, the conductive member 1013 may include only one opening, and the support member 104 may also include only one opening. As shown in FIG2 , when the optical detection module 102 includes both a transmitting end 1022 and a receiving end 1021, the conductive member 1013 may be provided with an opening at a corresponding position of the transmitting end 1022 and the receiving end 1021, and the support member 104 may also be provided with an opening at a corresponding position.

[0057] Optionally, the shape and size of the opening of the conductive member 1013 can be selected based on the receiving angle and emission angle of the optical detection module 102. Figures 3 and 4 show partial schematic diagrams of the conductive member 1013. As shown in Figure 3, in one example, the opening of the conductive member 1013 is a square opening. As shown in Figure 4, in another example, the opening of the conductive member 1013 is a circular opening.

[0058] Optionally, in the thickness direction x of the display screen 101 , the projection of the transparent conductive film 103 covers the receiving end 1021 .

[0059] 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 optical signals received by the receiving end 1021 are all optical signals that have been shielded from electromagnetic interference. It should be noted that in actual production, due to process limitations, the projection of the transparent conductive film 103 in the thickness direction x of the display screen 101 may not completely cover the receiving end 1021, but may leave a certain gap.

[0060] Optionally, the size and number of openings of the support member 104 can also be designed according to the structure of the optical detection module 102. Figures 5 and 6 show partial schematic diagrams of two different support members 104. In Figures 5 and 6, the thickness direction x of the display screen 101 is perpendicular to the paper surface.

[0061] As shown in FIG5 , in one example, when the optical detection module 102 includes both the transmitting end 1022 and the receiving end 1021, the support member 104 may include two openings, one opening corresponding to the receiving end 1021, and the opening is completely covered by the transparent conductive film 103; and the other opening corresponds to the transmitting end 1022, and the opening is not covered by the transparent conductive film. As shown in FIG6 , in another example, when the optical detection module 102 includes both the transmitting end 1022 and the receiving end 1021, the support member 104 may also include only one opening, and the one opening corresponds to both the transmitting end 1022 and the receiving end 1021. In this case, the transparent conductive film 103 only covers a portion of the opening.

[0062] 7 to 12 , the connection method between the transparent conductive film 103 and the ground terminal in the embodiment of the present application is described below.

[0063] FIG7 is a schematic structural diagram of a display device 300 of the present application.

[0064] As shown in Figure 7, the optical detection module 102 in the display device 300 includes a transmitting end 1022 and a receiving end 1021. The support member 104 is respectively provided with openings at positions corresponding to the transmitting end 1022 and the receiving end 1021, and at least part of the support member 104 extends between the optical detection module 102 and the display screen 101.

[0065] Optionally, as shown in FIG. 7 , the transparent conductive film 103 is connected to the support member 104 , and the support member 104 is connected to a ground terminal of the display device 300 .

[0066] Specifically, the support member 104 is a frame structure for supporting the display screen 101. The optical detection module 102 can be disposed in the accommodation space of the support member 104. As a result, at least a portion of the support member 104 is located between the optical detection module 102 and the display screen 101. By disposing the transparent conductive film 103 on the support member, the transparent conductive film 103 is located between the optical detection module 102 and the display screen 101. The support member 104 is generally 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 between the transparent conductive film 103 and the ground terminal of the display device 300 can be achieved.

[0067] Optionally, the electrical connection between the transparent conductive film 103 and other components may be achieved by pasting with a sticky conductive material, or by other methods such as welding.

[0068] Optionally, as shown in FIG. 7 , the transparent conductive film 103 is adhered to the support member 104 through a conductive adhesive 105 , and then electrically connected to the ground terminal of the display device 300 through the support member 104 .

[0069] In the embodiment of the present application, the transparent conductive film 103 is connected to the support member by bonding with the conductive adhesive 105. The connection method is simple and easy to implement, which helps in the automated production of the display device and helps improve the production efficiency of the display device.

[0070] Optionally, the support member 104 includes an electrical connection area for bonding with the conductive adhesive 105. The electrical connection area is a surface-treated area. For example, the surface treatment includes nickel plating, iron plating, etc.

[0071] Specifically, the support member 104 may be surface treated in the bonding area between the support member 104 and the conductive adhesive 105 to improve the conductivity of the area, thereby enhancing the reliability of the electrical connection between the conductive adhesive 105 and the support member 104 .

[0072] Optionally, as shown in FIG7 , the display device 300 further includes a mainboard 106, which is disposed below the optical detection module 102. Specifically, the mainboard 106 is a circuit board for controlling the display device 300. The mainboard 106 may be a ceramic circuit board, a PCB (Printed Circuit Board), an FPC (Flexible Printed Circuit Board), or the like, but the embodiments of the present application are not limited thereto. In one example, a grounding member may be provided on the mainboard 106, which serves as a ground terminal for the display device 300. In another example, the mainboard 106 may also be connected to a ground terminal of the display device 300.

[0073] Optionally, as shown in Figure 7, the display device 300 also includes a small board 1023, which is connected to the main board 106 and can transmit data with the main board 106. The small board 1023 is a circuit board provided to change the height of the optical detection module 102 in the display device 300, which can be connected to the optical detection module 102 group to control 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 integrated with the optical detection module 102 to form a whole; in other examples, the small board 1023 can also exist independently.

[0074] Optionally, as shown in FIG7 , a blocking member 107 is provided between the transmitting end 1022 and the receiving end 1021 to prevent crosstalk between the optical signal emitted by the transmitting end 1022 and the receiving end 1021. Specifically, the blocking member 107 may be a material capable of blocking optical signals, such as black foam. In one example, as shown in FIG5 and FIG6 , the blocking member 107 may be provided around the transmitting end 1022 to enhance the blocking effect on the optical signal emitted by the transmitting end 1022.

[0075] Optionally, the blocking member 107 is disposed on the supporting member 104 .

[0076] Specifically, the support member 104 shown in FIG7 is provided with openings at the transmitting end 1022 and the receiving end 1021, respectively. Therefore, a portion of the support member 104 exists between the transmitting end 1022 and the receiving end 1021. A blocking member 107 can be provided on the support member 104 to prevent light crosstalk between the transmitting end 1022 and the receiving end 1021.

[0077] Continuing with FIG7 , the transparent conductive film 103 optionally includes a transparent substrate 1031 and a conductive layer 1032 disposed on at least one side of the transparent substrate 1031. It should be noted that FIG7 only illustrates the case where the conductive layer 1032 is disposed on one side of the transparent substrate 1031. In other examples, the conductive layer 1032 may be disposed on both sides of the transparent substrate 1031. In the embodiments of the present application, the connection between the transparent conductive film 103 and other components refers to the connection between the conductive layer 1032 of the transparent conductive film 103 and other components.

[0078] Optionally, the conductive layer 1032 includes at least one of indium tin oxide (ITO), fluorine-doped tin oxide (FTO), and nanosilver.

[0079] Optionally, the transparent substrate 1031 includes at least one of glass, polyethylene glycol terephthalate (PET), or other transparent substrates.

[0080] Optionally, the transparent conductive film 103 has a transmittance of greater than or equal to 95% for the incident light signal. In other words, the transparent conductive film 103 has a high light transmittance, which can reduce the attenuation of the incident light signal.

[0081] In the embodiment of the present application, a transparent substrate is used in combination with a transparent conductive film 103 of ITO or silver oxide, so that a high light transmittance and good electrical conductivity can be achieved.

[0082] Optionally, the conductive layer 1032 may be formed on the transparent substrate 1031 by magnetron sputtering, spin coating, spray coating, dip coating, etc. However, the embodiment of the present application is not limited thereto.

[0083] FIG8 is a schematic structural diagram of a display device 400 according to an embodiment of the present application.

[0084] In the embodiment shown in FIG8 , the transparent conductive film 103 is also connected to the support member 104. Compared to the display device 300 in FIG7 , the support member 104 in the display device 400 has only one opening at a position corresponding to the optical detection module 102. This opening corresponds to both the transmitting 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. By disposing the transparent conductive film 103 on the support member 104, the transparent conductive film 103 can also be located between the optical detection module 102 and the display screen 101, and electrically connected to the ground terminal of the display device 400 through the support member 104.

[0085] Optionally, the blocking member 107 is disposed on the optical detection module 102 .

[0086] Specifically, the support member 104 shown in Figure 8 is only provided with one opening. At this time, there is no longer a partial support member 104 structure above the optical detection module 102. The blocking member 107 can be directly provided on the optical detection module 102 to prevent light crosstalk between the transmitting end 1022 and the receiving end 1021.

[0087] FIG9 is a schematic structural diagram of a display device 500 of the present application.

[0088] Optionally, as shown in FIG. 9 , the transparent conductive film 103 may be connected to a conductive member 1013 , and the conductive member 1013 is connected to a ground terminal of the display device 500 .

[0089] Specifically, the conductive member 1013 of the display screen 101 can be a conductive metal member such as copper foil, and is disposed on the side of the display screen 101 facing the optical detection module 102. By disposing 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 an electrical connection is achieved between the transparent conductive film 103 and the ground terminal of the display device 500 through the conductive member 1013.

[0090] In the embodiment shown in FIG9 , the structure of the support member 104 is similar to that of the embodiment shown in FIG7 , with openings also provided at the transmitting end 1022 and the receiving end 1021, respectively, and a portion of the support member 104 existing between the transmitting end 1022 and the receiving end 1021. Therefore, in the embodiment shown in FIG9 , a blocking member 107 can be provided on the support member 104 to prevent light crosstalk between the transmitting end 1022 and the receiving end 1021.

[0091] FIG10 is a schematic structural diagram of a display device 600 of the present application.

[0092] In the embodiment shown in FIG10 , the transparent conductive film 103 is also connected to the conductive member 1013. Compared to the display device 500 in FIG9 , the support member 104 in the display device 600 has only one opening at a position corresponding to the optical detection module 102. This opening corresponds to both the transmitting 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. Thus, similar to the embodiment shown in FIG8 , the blocking member 107 can be directly disposed on the optical detection module 102 to prevent light crosstalk between the transmitting end 1022 and the receiving end 1021.

[0093] Figure 11 is a schematic structural diagram of a display device 700 of the present application. Figure 12 is a schematic structural diagram of a display device 800 of the present application.

[0094] Optionally, as shown in FIG. 11 and FIG. 12 , the transparent conductive film 103 is disposed on the optical detection module 102 and connected to the main board 106 .

[0095] Specifically, the transparent conductive film 103 can also be directly disposed on the optical detection module 102, covering the receiving end 1021 of the optical detection module 102, and connected to the mainboard 106. Thus, the connection with the ground terminal of the display device 700, the display device 800 is achieved.

[0096] For example, the transparent conductive film 103 can be adhered to the optical detection module 102 via double-sided tape 108 and connected to the main board 106 via conductive adhesive 105. It should be noted that the connection between the transparent conductive film 103 and the main board 106 can be a direct connection or connected via other components. Figures 11 and 12 both illustrate the connection via other components.

[0097] 11 and 12 , transparent conductive film 103 is connected to small plate 1023, which is in turn connected to main plate 106. In other words, transparent conductive film 103 is connected to main plate 106 via small plate 1023, thereby achieving connection to the ground terminals of display devices 700 and 800.

[0098] In the embodiment shown in Figure 11, the small board 1023 is connected to the main board 106 by welding. In the embodiment shown in Figure 12, the small board 1023 is connected to the main board 106 by contacts or connectors.

[0099] It should be noted that the soldering between the small board 1023 and the main board 106 can be performed using surface mount technology (SMT). When using this technology, the small board 1023 can be soldered to the main board 106 first, and then the transparent conductive film 103 can be attached to the optical detection module 102 to prevent the transparent conductive film 103 from being damaged and thus failing during the soldering process.

[0100] Optionally, the main board 106 and the sub-board 1023 may include a processing unit. The processing unit may be a central processing unit (CPU), or may be another general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. The general-purpose processor may be a microprocessor or any conventional processor.

[0101] An embodiment of the present application further provides an electronic device, which may include the display device in any of the above embodiments.

[0102] The devices and methods disclosed in the embodiments of the present application can be implemented in other ways.
