Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] The embodiment of the present application provides a display device 100, which includes a display panel 10, a first circuit board 20, a second circuit board 30, a first flexible circuit board 40, and at least one microphone module 50. The display panel 10 has a display surface 11. The first circuit board 20 is arranged on a side of the display panel 10 away from the display surface 11. The second circuit board 30 is arranged near the edge of the display panel 10. At least one microphone module 50 is arranged on the second circuit board 30 and is electrically connected to the second circuit board 30. The first flexible circuit board 40 is electrically connected to the first circuit board 20 and the second circuit board 30 respectively.

[0036] The display panel 10 includes a display surface 11 and a non-display surface 12, wherein the display surface 11 refers to the side of the display device 100 that displays images to the user when working, and the non-display surface 12 is arranged opposite to the display surface 11. The first circuit board 20 is arranged on the non-display surface 12. The projection of the first circuit board 20 on the plane where the display panel 10 is located is located within the range of the display panel 10.

[0037] The display panel 10 may be a liquid crystal panel, an organic light emitting diode (OLED) display panel, a quantum dot light emitting diode (QLED) display panel, an electronic paper panel, etc. The display panel 10 may have any size and type, and the embodiments of the present disclosure are not limited thereto. For example, the display panel 10 may be a twisted nematic (TN) type liquid crystal panel, an advanced super-dimensional field switching (ADS) type liquid crystal panel, an in-plane switching (IPS) type liquid crystal panel, a vertical alignment (VA) type liquid crystal panel, an active matrix organic light emitting diode (AMOLED) type display panel 10, a passive matrix organic light emitting diode (PMOLED) type display panel 10, etc. For example, the size of the display panel 10 may be 32 inches, 55 inches, 75 inches, 110 inches, etc. For example, the thickness of the display panel 10 may be less than or equal to 20 mm, such as 20 mm, 18 mm, 16 mm, etc.

[0038] In the display device 100 provided by the embodiments of the present application, the number of the first circuit board 20, the second circuit board 30, and the first flexible circuit board 40 is one. In fact, the number of the first circuit board 20, the second circuit board 30, and the first flexible circuit board 40 can be multiple. The embodiments of the present disclosure do not limit the number of the first circuit board 20, the second circuit board 30, and the first flexible circuit board 40 of the display device 100.

[0039] At least one of the first circuit board 20 and the second circuit board 30 is a non-flexible circuit board. For example, both the first circuit board 20 and the second circuit board 30 are rigid circuit boards. When both the first circuit board 20 and the second circuit board 30 are rigid circuit boards, the reliability of the first circuit board 20 and the second circuit board 30 is improved, and they are more firmly connected to the first flexible circuit board 40.

[0040] The plane where the first circuit board 20 is located and the plane where the second circuit board 30 is located can be close to perpendicular to better fit the shape of the display panel 10.

[0041] The thickness of the first circuit board 20 is small and can be less than or equal to 2 mm. For example, the thickness of the first circuit board 20 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.8 mm. Since the thickness of the first circuit board 20 is small, the influence of the first circuit board 20 on the thickness of the display device 100 when it is arranged on the non-display surface 12 of the display panel 10 is small.

[0042] The second circuit board 30 can be arranged on the lower border of the display device 100. The thickness of the second circuit board 30 is also small and can be less than or equal to 2 mm. For example, the thickness of the second circuit board 30 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.3 mm, 1.5 mm, 1.8 mm. The second circuit board 30 can be a double-sided circuit board, that is, electronic components can be mounted on both sides, improving the space utilization rate. Since the thickness of the second circuit board 30 is small, the influence of the second circuit board 30 on the border width of the display device 100 when it is arranged on the side of the display panel 10 is small.

[0043] The flexible circuit board is also called a flexible printed circuit board. One end of the first flexible circuit board 40 can be connected to the side of the first circuit board 20 facing the display panel 10, or can be connected to the side of the first circuit board 20 away from the display panel 10; the other end of the first flexible circuit board 40 can be connected to any position of the second circuit board 30. The flexible circuit board is bent and has the characteristics of flexibility and shock resistance.

[0044] The first flexible circuit board 40 can be a single-sided board or a double-sided board. When the first flexible circuit board 40 is a double-sided board, wiring can be routed on both sides of the first flexible circuit board 40 to avoid mutual influence of wiring and improve anti-interference capability.

[0045] The flexible circuit board may be connected to the first circuit board 20 or the second circuit board 30 by soft-hard pressing or bonding.

[0046] When the display device 100 is in use, the display panel 10 faces the user, and the second circuit board 30 is closer to the user than the first circuit board 20, and is not blocked by the display panel 10. The microphone module 50 is disposed on the second circuit board 30 to better receive the user's voice to improve functionality.

[0047] Therefore, in the display device 100 and the television provided in the embodiment of the present application, the display device 100 includes a display panel 10, a first circuit board 20, a second circuit board 30, a microphone module 50 and a first flexible circuit. The first circuit board 20, the first flexible circuit board 40 and the second circuit board 30 are connected in sequence. The first circuit board 20 is arranged on the side of the display panel 10 away from the display surface 11, and the second circuit board 30 is arranged close to the edge of the display panel 10. In addition, the microphone module 50 is mounted on the second circuit board 30, which can effectively improve the sound pickup effect compared to being arranged on the back of the display panel 10. Compared with the solution of arranging all circuit boards on the side or back of the display panel 10, the display device 100 provided in the present application can not only narrow the frame of the display device 100, but also realize the thinness of the display device 100, and can also ensure the sound pickup effect.

[0048] Please continue reading Figure 1 as well as Figure 3 The microphone module 50 can be arranged at the edge of the second circuit board 30 away from the first circuit board 20 to be closer to the user and better receive sound. The microphone module 50 can be a horizontal patch.

[0049] In some embodiments, there are multiple microphone modules 50 , and the microphone modules 50 are arrayed on the second circuit board 30 to improve the sound reception effect. For example, there are four microphone modules 50 , and the four microphone modules 50 are evenly distributed on the second circuit board 30 .

[0050] In some cases, when there are two microphone modules 50 , the distance between the two microphone modules 50 is 60 mm to 80 mm. For example, the distance between the two microphone modules 50 is 70 mm.

[0051] In other cases, when the number of the microphone modules 50 is four, the distance between adjacent microphone modules 50 is 30 mm to 40 mm. For example, the distance between adjacent microphone modules 50 is 35 mm.

[0052] When the distance between adjacent microphone modules 50 is the above distance, the sound pickup ability of the microphone module 50 can be improved.

[0053] In some embodiments, the display device 100 further includes a housing (not shown in the figure), and the housing has an accommodation space. The microphone module 50 is disposed in the accommodation space, and a sound pickup hole corresponding to the microphone module 50 is provided on the housing. The sound pickup hole can also be referred to as a sound receiving hole. The microphone module 50 can pick up sound through the sound pickup hole on the housing.

[0054] When the number of the microphone modules 50 is multiple, the sound pickup holes also have the same number. The microphone modules 50 are disposed in one-to-one correspondence with the sound pickup holes of the housing.

[0055] It should be noted that the accommodation space of the housing can also accommodate the display panel 10, the first circuit board 20, and the second circuit board 30, playing a protective role.

[0056] In some embodiments, please refer to Figure 3 and Figure 4 , Figure 4 which is the second partial structural schematic diagram of the display device provided by the embodiment of the present application. The display device 100 further includes a radio frequency antenna 60, and the radio frequency antenna 60 is disposed on the second circuit board 30. The radio frequency antenna 60 and the microphone module 50 are respectively disposed on two opposite surfaces of the second circuit board 30. The radio frequency antenna 60 and the microphone module 50 are respectively disposed on two surfaces of the second circuit board 30.

[0057] It can be understood that the second circuit board 30 can be a double-sided circuit board having two opposite surfaces. One surface can be used to dispose the microphone module 50, and the other surface can be used to dispose the radio frequency antenna 60. Disposing the microphone module 50 and the radio frequency antenna 60 on two surfaces of the second circuit board 30 can prevent the two structures from interfering with each other, improve the sound pickup quality of the microphone module 50, and form a clearance area for the radio frequency antenna 60 to improve the signal transceiver quality of the radio frequency antenna 60.

[0058] Among them, the radio frequency antenna 60 includes a Bluetooth antenna 61 and a plurality of WiFi antennas 62. The plurality of WiFi antennas 62 are symmetrically arranged on both sides of the Bluetooth antenna 61. In the embodiment of the present application, the number of the WiFi antennas 62 is four. Two WiFi antennas 62 are arranged on one side of the Bluetooth antenna 61, and the other two WiFi antennas 62 are arranged on the other side of the Bluetooth antenna 61. Through the above settings, a single WiFi antenna function module capable of omnidirectional radiation is formed, which can make full use of the space of the second circuit board 30 and ensure the stability of signal transmission and reception of the radio frequency antenna 60.

[0059] Among them, the radio frequency antenna 60 is a three-dimensional structure, which increases the distance from metals (the second circuit board 30, the microphone module 50) to form a clearance area, thereby improving the quality of signal transmission and reception of the radio frequency antenna 60.

[0060] On one side of the second circuit board 30 where the radio frequency antenna 60 is arranged, a grounding point and / or a grounding circuit are arranged. The grounding point and / or the grounding circuit are connected to the radio frequency antenna 60 to ground the radio frequency antenna 60.

[0061] Correspondingly, the display device 100 further includes a radio frequency signal processing module. The radio frequency signal processing module is arranged on the first circuit board 20. The first flexible circuit board 40 includes radio frequency signal lines, and the radio frequency signal lines are electrically connected to the radio frequency antenna 60 and the radio frequency signal processing module respectively.

[0062] It can be understood that the radio frequency antenna 60 for transmitting and receiving radio frequency signals is arranged on the second circuit board 30. The second circuit board 30 is closer to the user and the outside world than the first circuit board 20, so the effect of transmitting and receiving radio frequency signals is better. The radio frequency signal processing module is arranged on the first circuit board 20 to free up the space on the second circuit board 30, so that as many modules as possible that need to transmit and receive signals can be arranged on the second circuit board 30.

[0063] Therefore, the display device 100 further includes a light sensor module and / or a voice sensor module. The light sensor module and / or the voice sensor module are arranged on the second circuit board 30. The light sensor module and / or the voice sensor module and the microphone module 50 are arranged on the same surface of the second circuit board 30. The light sensor module includes an infrared sensor or a light intensity sensor, which is used to receive infrared signals or sense the external light intensity.

[0064] In some embodiments, the display device 100 further includes a power supply circuit, an interface circuit or a signal processing circuit. The power supply circuit, the interface circuit or the signal processing circuit are arranged on the first circuit board 20.

[0065] The power supply circuit may include at least one of the following: an LDO (Low Dropout Voltage Regulator) circuit, a Boost converter, a positive charge pump (Positive Charge Bump), a negative charge pump (Negative Charge Bump), a voltage divider circuit, etc.

[0066] The interface circuit can be used, for example, to receive a signal from a system (e.g., a motherboard of a complete machine), and input a digital signal in the received signal to a signal processing circuit (e.g., a timing control circuit), and input a power signal in the received signal to a power circuit. The interface circuit can include, for example, at least one of the following: a TTL (Transistor Transistor Logi, transistor-transistor logic circuit) interface, a TMDS (Transition Minimized Differential Signaling, minimized transmission differential signal) interface, an LVDS (Low Voltage Differential Signaling, low voltage differential signal) interface, etc.

[0067] The signal processing circuit may include a timing control circuit, a grayscale circuit, etc. For example, the timing control circuit may provide control signals to the scan driving circuit and the data driving circuit of the display panel 10, and the grayscale circuit may provide a gamma reference voltage to the data driving circuit of the display panel 10.

[0068] In some embodiments, please refer to Figure 5 , Figure 5 The third partial structural diagram of the display device provided in the embodiment of the present application. The display device 100 also includes a movement and a second flexible circuit board 70, the movement is arranged on the side of the display panel 10 away from the display surface 11, and the second flexible circuit board 70 is electrically connected to the first circuit board 20 and the movement.

[0069] The core is usually composed of multiple chips such as CPU, GPU, MEM, ROM, RAM, etc. Among them, CPU is the main core of the core, which determines the overall performance of the TV. GPU is responsible for processing the picture, MEM and ROM are used to store data and programs, and RAM is a temporary storage.

[0070] The second flexible circuit board 70 includes a power supply circuit and a signal transmission circuit. Through the second flexible circuit board 70, the power module on the first circuit board 20 can power the movement, and the movement can transmit signals to the electronic components on the first circuit board 20 or the second circuit board 30, or the electronic components on the first circuit board 20 or the second circuit board 30 can transmit signals to the movement.

[0071] In some embodiments, the display device 100 further includes a backlight source and a driving circuit, and at least one of the backlight source and the driving circuit is electrically connected to the first circuit board 20 .

[0072] The driving circuit may be, for example, a scanning driving circuit and / or a data driving circuit. The backlight source provides a light source for display. The backlight source may be of various types, such as a direct backlight source or an edge-lit backlight source.

The first sub-flexible circuit and the second sub-flexible circuit can be electrically connected to the first circuit board 20, for example, by bonding. In other embodiments, the first sub-flexible circuit and the second sub-flexible circuit can be bonded to the first circuit board 20 by anisotropic conductive adhesive.

[0074] The present application also provides a television set, comprising the display device 100 in the above embodiment.
