[0025] The embodiment of the present application provides a display device 100, which comprises 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 close to an edge of the display panel 10. The at least one microphone module 50 is arranged on the second circuit board 30 and electrically connected with the second circuit board 30. The first flexible circuit board 40 is electrically connected with the first circuit board 20 and the second circuit board 30 respectively. The display panel 10 comprises the display surface 11 and a non-display surface 12, the display surface 11 refers to a side of the display device 100 displaying images to a user when the display device 100 is 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. A projection of the first circuit board 20 on a plane where the display panel 10 is located is within a range of the display panel 10. The display panel 10 can be one of 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 and the like. The display panel 10 can have any size and type, and the embodiment of the present application does not limit this. For example, the display panel 10 can be a twisted nematic (TN) liquid crystal panel, an advanced super dimension switch (ADS) liquid crystal panel, an in-plane switching (IPS) liquid crystal panel, a vertical alignment (VA) liquid crystal panel, an active matrix organic light-emitting diode (AMOLED) display panel 10, a passive matrix organic light-emitting diode (PMOLED) display panel 10 and the like. For example, the size of the display panel 10 can be 32 inches, 55 inches, 75 inches, 110 inches and the like. For example, the thickness of the display panel 10 can be less than or equal to 20 mm, for example, 20 mm, 18 mm, 16 mm and the like.

[0026] The display device 100 provided by the embodiments of the present application has one first circuit board 20, one second circuit board 30 and one first flexible circuit board 40. In fact, the number of the first circuit board 20, the second circuit board 30 and the first flexible circuit board 40 can be more. The embodiments of the present application 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.

[0027] At least one of the first circuit board 20 and the second circuit board 30 is a non-flexible circuit board. For example, the first circuit board 20 and the second circuit board 30 are both rigid circuit boards. When the first circuit board 20 and the second circuit board 30 are both rigid circuit boards, the reliability of the first circuit board 20 and the second circuit board 30 is improved, and the first circuit board 20 and the second circuit board 30 are more firmly connected with the first flexible circuit board 40. 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 vertical, so as to be more in line with the shape of the display panel 10.

[0028] The thickness of the first circuit board 20 is small, which 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 first circuit board 20 has little effect on the thickness of the display device 100 when the first circuit board 20 is arranged on the non-display surface 12 of the display panel 10.

[0029] The second circuit board 30 can be arranged on the lower side frame of the display device 100. The thickness of the second circuit board 30 is also small, which 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 carried on both sides, improving the space utilization. Since the thickness of the second circuit board 30 is small, the second circuit board 30 has little effect on the width of the side frame of the display device 100 when the second circuit board 30 is arranged on the side of the display panel 10.

[0030] The flexible circuit board is also called flexible printed circuit board. One end of the first flexible circuit board 40 can be connected with the side of the first circuit board 20 facing the display panel 10, or 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 with any position of the second circuit board 30. The flexible circuit board is curved and has the characteristics of flexibility and impact resistance.

[0031] 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, both sides of the first flexible circuit board 40 can be wired, avoiding mutual influence of the lines and improving the anti-interference capability.

[0032] The connection mode of the flexible circuit board and the first circuit board 20 or the second circuit board 30 can be a soft and hard lamination mode or a bonding mode.

[0033] Since the display device 100 is used in the process, the display panel 10 faces the user at the same time, 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 arranged on the second circuit board 30 can better accept the user's voice to improve the functionality.

[0034] Therefore, in the display device 100 and the television provided in the embodiments 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 carried on the second circuit board 30, which can effectively improve the sound pickup effect compared with being arranged on the back of the display panel 10. Compared with the scheme of arranging the 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 lightness and thinness of the display device 100, and also can guarantee the sound pickup effect. Please continue to refer to FIG. 1 and FIG. 3, the microphone module 50 can be arranged on the edge of the second circuit board 30 away from the first circuit board 20, so as to be closer to the user and better receive sound. The microphone module 50 can be selected as a horizontal patch.

[0035] In some embodiments, the number of microphone modules 50 is multiple, and the microphone modules 50 are arranged in an array on the second circuit board 30, which can improve the sound pickup effect. For example, the number of microphone modules 50 is four, and the four microphone modules 50 are uniformly distributed on the second circuit board 30.

[0036] In some cases, when the number of microphone modules 50 is two, the distance between the two microphone modules 50 is 60mm to 80mm. For example, the distance between the two microphone modules 50 is 70mm.

[0037] In other cases, when the number of microphone modules 50 is four, the distance between adjacent microphone modules 50 is 30mm to 40mm. For example, the distance between adjacent microphone modules 50 is 35mm.

[0038] When the distance between adjacent microphone modules 50 is the above distance, the sound collection capability of the microphone modules 50 can be improved. In some embodiments, the display device 100 further includes a housing (not shown in the figure) having an accommodation space. The microphone modules 50 are arranged in the accommodation space, and the housing is provided with sound collection holes corresponding to the microphone modules 50. The sound collection holes can also be referred to as sound collection holes. The microphone modules 50 can collect sound through the sound collection holes on the housing.

[0039] When the number of microphone modules 50 is multiple, the number of sound collection holes is also multiple. The microphone modules 50 are arranged one by one corresponding to the sound collection holes of the housing.

[0040] It is worth noting 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, and play a protection role.

[0041] In some embodiments, referring to FIG. 3 and FIG. 4, FIG. 4 is a second partial structure diagram of a display device provided by an embodiment of the present application. The display device 100 further includes a radio frequency antenna 60, which is arranged on the second circuit board 30. The radio frequency antenna 60 and the microphone modules 50 are arranged on opposite surfaces of the second circuit board 30, respectively. The radio frequency antenna 60 and the microphone modules 50 are arranged on the two surfaces of the second circuit board 30, respectively.

[0042] It can be understood that the second circuit board 30 can be a double-sided circuit board having two opposite surfaces, one of which can be arranged with the microphone modules 50, and the other of which can be arranged with the radio frequency antenna 60. Arranging the microphone modules 50 and the radio frequency antenna 60 on the two surfaces of the second circuit board 30 does not interfere with the two structures, improves the sound collection quality of the microphone modules 50, and forms a clearance for the radio frequency antenna 60 to improve the signal receiving and transmitting quality of the radio frequency antenna 60.

[0043] The radio frequency antenna 60 includes a Bluetooth antenna 61 and a plurality of WiFi antennas 62, and 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 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 arrangement, 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 the signal receiving and transmitting of the radio frequency antenna 60.

[0044] The radio frequency antenna 60 is a three-dimensional structure, which increases the distance from the metal (the second circuit board 30 and the microphone modules 50) to form a clearance, thereby improving the signal receiving and transmitting quality of the radio frequency antenna 60.

[0045] The side of the second circuit board 30 on which the radio frequency antenna 60 is arranged is provided with a grounding point and / or grounding circuit, which is connected with the radio frequency antenna 60 to ground the radio frequency antenna 60.

The radio frequency signal processing module is arranged on the first circuit board 20 to free up space on the second circuit board 30, so that as many modules as possible that need to transmit and receive signals are arranged on the second circuit board 30.

[0048] Therefore, the display device 100 further comprises a light sensor module and / or a voice sensor module, which are arranged on the second circuit board 30. The light sensor module and / or the voice sensor module are arranged on the same surface of the second circuit board 30 as the microphone module 50. The light sensor module comprises an infrared sensor or a light intensity sensor, which is used to receive an infrared signal or sense the light intensity of the outside world.

The interface circuit can include at least one of a TTL (Transistor Transistor Logic) interface, a TMDS (Transition Minimized Differential Signaling) interface, a LVDS (Low Voltage Differential Signaling) interface, and the like.

[0052] The signal processing circuit can include a timing control circuit, a gray scale circuit, and the like. For example, the timing control circuit can provide control signals to a scan driving circuit and a data driving circuit of the display panel 10, and the gray scale circuit can provide a Gamma reference voltage to the data driving circuit of the display panel 10.
