[0024] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0025] The present application provides a circuit board, a display device and a television set, which can visually compress the volume and still have more space to arrange functional devices to maintain the original functions. The following will be specifically described with reference to the drawings.

[0026] Please refer to Figure 1 , Figure 1 A schematic diagram of a circuit board and a display panel provided by an embodiment of the present application.

[0027] An embodiment of the present application provides a circuit board 102, which is applied to a display panel 101.

[0028] Please refer to Figure 2 and Figure 3 , Figure 2 A partial A of Figure 1 enlarged schematic diagram, Figure 3 A structural schematic diagram of a circuit board provided by an embodiment of the present application.

[0029] The circuit board 102 includes a first sub-circuit board 1021 and a second sub-circuit board 1022, the second sub-circuit board 1022 protrudes from the first sub-circuit board 1021, and the width of the first sub-circuit board 1021 is greater than the width of the second sub-circuit board 1022. For example, the planar shape of the circuit board 102 is similar to a “convex” shape.

[0030] The width of the first sub-circuit board 1021 can be 100mm to 120mm, for example, 110mm, and the width of the second sub-circuit board 1022 can be 20mm to 30mm, for example, 25mm. The length of the first sub-circuit board 1021 along the thickness direction of the display panel 101 can be 13mm to 15mm, for example, 14mm, and the length of the second sub-circuit board 1022 along the thickness direction of the display panel 101 can be 7mm to 9mm, for example, 8mm.

[0031] The projection of the second sub-circuit board 1022 along the connection direction of the first sub-circuit board 1021 and the second sub-circuit board 1022 is located in the first sub-circuit board 1021, so that when the user uses the display device 100, due to the inconsistency in width of the first sub-circuit board 1021 and the second sub-circuit board 1022, the first sub-circuit board 1021 and the second sub-circuit board 1022 overlap in the line of sight in the protruding direction of the second sub-circuit board 1022, which is equivalent to the second sub-circuit board 1022 being hidden in the first sub-circuit board 1021, reducing the volume of the second sub-circuit board 1022 in the user's field of view, which can not only visually compress the volume, but also still have more space to arrange functional devices to maintain the original function.

[0032] Please continue to refer to Figure 2 The circuit board 102 includes an acoustic component 106 and a light sensing component 107, the acoustic component 106 is arranged on the first sub-circuit board 1021, and the light sensing component 107 is arranged on the second sub-circuit board 1022.

[0033] The acoustic component 106 includes a plurality of microphones, and the plurality of microphones are arranged in an array on the first sub-circuit board 1021, which can improve the sound collection effect. For example, the number of microphones is four, and the four microphones are uniformly distributed on the first sub-circuit board 1021. The microphone can enhance the user's interactive experience and provide entertainment functions.

[0034] The microphone can be arranged at a distance of 6-9mm, for example, 8mm, from the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021.

[0035] Please continue to refer to Figure 2 The light sensing component 107 includes a light sensor and / or an infrared receiving sensor, and the light sensor and / or the infrared receiving sensor are arranged on the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021.

[0036] It can be understood that the light sensing component 107 can be only a light sensor, only an infrared receiving sensor, or both a light sensor and an infrared sensor.

[0037] The light sensor is mainly used for automatically adjusting the brightness and color temperature of the display panel to adapt to different light environments, providing a more comfortable viewing experience, and saving energy.

[0038] The infrared receiving sensor is mainly used for receiving infrared signals emitted by a remote controller and converting them into electrical signals to control various functions of the display device 100. The infrared receiving sensor receives specific infrared light signals emitted by the remote controller to identify user operation instructions such as power on / off, channel switching, and volume adjustment.

[0039] Therefore, the light sensor needs to capture ambient light sharply, or the infrared receiving sensor needs to receive the infrared signal from the remote control in time. Therefore, the light sensing component 107 is arranged at the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021, so as to avoid the interference of other electronic devices on the second sub-circuit board 1022, and thus improve the detection or recognition accuracy of the light sensing component 107.

[0040] Please continue to refer to Figure 2 The display device 100 further comprises a power switch 108 and / or an indicator light 109, which are arranged on the second sub-circuit board 1022. The power switch 108 can accept mechanical pressing of the user, and the indicator light 109 is beneficial to prompting the user.

[0041] Please refer to Figure 4 , Figure 4 The first structure diagram of the display device provided by the embodiment of the present application.

[0042] The display device 100 provided by the embodiment of the present application can be a television set. The display device 100 comprises a display panel 101 and a first circuit board, which is the circuit board 102 in the above embodiment.

[0043] Please refer to Figure 5 , Figure 5 The second structure diagram of the display device provided by the embodiment of the present application.

[0044] The display panel 101 has opposite display side 1011 and non-display side 1012, and the display side 1011 refers to the side of the display device 100 displaying images to the user when working. Specifically, the display panel 101 further has a side surface connected with the display side 1011 and the non-display side 1012 respectively. The first circuit board 102 is arranged corresponding to the side surface. The first circuit board 102 is arranged at the edge of the display panel 101. Specifically, the plane where the first circuit board 102 is arranged is parallel to the side surface of the display panel 101. It can be understood that the first circuit board 102 is arranged at the edge of the display panel 101, the first circuit board 102 is in a plate structure and has a thin thickness, which is beneficial to the narrow frame effect of the display device 100, and thus improves the appearance of the display device 100.

[0045] Please refer to Figure 6 , Figure 6 The partial structure diagram of the display device provided by the embodiment of the present application.

[0046] The first circuit board 102 includes a first sub-circuit board 1021 and a second sub-circuit board 1022. In the thickness direction of the display panel 101, the second sub-circuit board 1022 extends from the first sub-circuit board 1021 toward the display side 1011. In other words, in the direction from the non-display side 1012 of the display panel 101 toward the display side 1011, the first sub-circuit board 1021 and the second sub-circuit board 1022 are arranged in sequence. The first sub-circuit board 1021 and the second sub-circuit board 1022 are located on the same plane.

[0047] In some cases, the width of the second sub-circuit board 1022 is less than the width of the first sub-circuit board 1021. It can be understood that the width of the first sub-circuit board 1021 refers to the length of the first sub-circuit board 1021 in the extension direction W of the edge of the display panel 101, or perpendicular to the thickness direction of the display panel 101. Similarly, the width of the second sub-circuit board 1022 refers to the length of the second sub-circuit board 1022 in the extension direction W of the edge of the display panel 101, or perpendicular to the thickness direction of the display panel 101. That is, the width of the second sub-circuit board 1022 is less than the width of the first sub-circuit board 1021, so that the first circuit board 102 presents a "convex" shape.

[0048] Please continue to refer to Figure 4 The projection of the second sub-circuit board 1022 in the thickness direction of the display panel 101 is located in the first sub-circuit board 1021, so that the first sub-circuit board 1021 and the second sub-circuit board 1022 overlap in the line of sight when the user uses the display device 100, which is equivalent to the second sub-circuit board 1022 hidden in the first sub-circuit board 1021, reducing the volume of the second sub-circuit board 1022 in the user's field of view, thereby improving the appearance of the display device 100.

[0049] The display device 100 further includes a housing, which at least includes a first housing 104 and a second housing 105 arranged on the first housing 104. The first housing 104 covers the first sub-circuit board 1021, and the second housing 105 covers the second sub-circuit board 1022. The first housing 104 and the second housing 105 can include the first sub-circuit board 1021 and the second sub-circuit board 1022. The first housing 104 and the second housing 105 are in communication with each other.

[0050] Since the width of the second sub-circuit board 1022 is smaller than the width of the first sub-circuit board 1021, correspondingly, the width of the second shell 105 is smaller than the width of the first shell 104, so that when the user uses the display device 100, the first shell 104 and the second shell 105 overlap in the line of sight, which means that the second shell 105 is hidden in the first shell 104, reducing the volume of the second shell 105 in the user's field of view, thereby improving the appearance of the display device 100.

[0051] Please continue to refer to Figure 5 and Figure 6 The display device 100 includes a front frame assembly 103 surrounding the display panel 101, and the first circuit board 102 is arranged on the side of the front frame assembly 103 away from the display panel 101. Further, the first circuit board 102 can be arranged corresponding to the bottom of the display device 100, and the first shell 104 and the second shell 105 can be connected with the front frame assembly 103 corresponding to the bottom of the display device 100.

[0052] Please refer to Figure 7 , Figure 7 The first structure diagram of the circuit board of the display device provided by the embodiment of the application is shown. The acoustic component 106 is arranged on the first sub-circuit board 1021, and the light sensing component 107 is arranged on the second sub-circuit board 1022.

[0053] As can be seen, when the user uses the display device 100, the second sub-circuit board 1022 is closer to the user, and the light sensing component 107 carried on the second sub-circuit board 1022 is more likely to receive changes in the intensity of external light and / or control instructions from the remote controller, while the first sub-circuit board 1021 is slightly farther away from the user than the second sub-circuit board 1022, and the acoustic component 106 carried on the first sub-circuit board 1021 can receive voice instructions from the user. Since the first sub-circuit board 1021 and the second sub-circuit board 1022 are arranged in sequence along the thickness direction of the display panel 101, the structure in the thickness direction of the display panel 101 is overlapped, which makes the user visually think that the second sub-circuit board 1022 is hidden in the first sub-circuit board 1021, which is conducive to the narrow frame effect of the display device 100, thereby improving the appearance of the display device 100.

[0054] The acoustic component 106 includes a plurality of microphones, which are arrayed on the first sub-circuit board 1021, which can improve the sound pickup effect. For example, the number of microphones is four, and the four microphones are uniformly distributed on the first sub-circuit board 1021. The microphone can enhance the user's interactive experience and provide entertainment functions.

[0055] The microphone can be arranged at a distance of 6-9mm, for example 8mm, from the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021.

[0056] Please continue to refer to Figure 6 and Figure 8 , Figure 8 For Figure 5 the enlarged schematic view of part B. The first shell 104 is provided with a pickup hole 1041, and the pickup hole 1041 is arranged corresponding to the acoustic assembly 106. The pickup hole 1041 is arranged on the side of the first shell 104 close to the second shell 105, or can be arranged on the side of the first shell 104 away from the display panel 101, to correspond to the acoustic assembly 106 as a front sound guide type and a bottom sound guide type respectively. Relatively speaking, when the acoustic assembly 106 is a bottom sound guide type, the shell thickness of the first shell 104 is lower.

[0057] The pickup hole 1041 can also be called a sound collecting hole. The microphone can collect sound through the pickup hole 1041 on the first shell 104.

[0058] When the number of microphones is multiple, the number of pickup holes 1041 is also the same. The microphone is arranged one-to-one corresponding to the pickup hole 1041.

[0059] Please continue to refer to Figure 7 The light sensing assembly 107 includes a light sensor and / or an infrared receiving sensor, and the light sensor and / or the infrared receiving sensor are arranged on the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021.

[0060] It can be understood that the light sensing assembly 107 can be only a light sensor, only an infrared receiving sensor, or both a light sensor and an infrared sensor.

[0061] The light sensor is mainly used for automatically adjusting the brightness and color temperature of the display panel to adapt to different light environments, provide a more comfortable viewing experience, and save energy.

[0062] The infrared receiving sensor is mainly used for receiving the infrared signal emitted by the remote controller and converting it into an electric signal, so as to control various functions of the display device 100. The infrared receiving sensor identifies the user's operation instructions such as power on / off, channel switching, volume adjustment, etc. by receiving specific infrared light signals emitted by the remote controller.

[0063] Therefore, the light sensor needs to capture ambient light sharply, or the infrared receiving sensor needs to receive the infrared signal from the remote control in time. Therefore, the light sensing component 107 is arranged at the edge of the second sub-circuit board 1022 away from the first sub-circuit board 1021 to extend closer to the display side 1011 of the display panel 101, thereby improving the detection or recognition accuracy of the light sensing component 107.

[0064] Please continue to refer to Figure 7 , the first circuit board 102 further comprises a power switch 108 and / or an indicator light 109, which are arranged on the second sub-circuit board 1022. The power switch 108 arranged on the second sub-circuit board 1022 closer to the user is conducive to the user's continuous operation. The indicator light 109 is conducive to the user's awareness of the state of the display device 100.

[0065] In some embodiments, please continue to refer to Figure 9 、 Figure 10 and Figure 11 , Figure 9 the third structural schematic diagram of the display device provided by the embodiments of the present application, Figure 10 is Figure 9 an enlarged schematic diagram of part C of Figure 11 the second structural schematic diagram of the circuit board of the display device provided by the embodiments of the present application.

[0066] The display device 100 comprises a second circuit board 110 and an antenna component 111, the antenna component 111 is arranged on the second circuit board 110, the second circuit board 110 is arranged on the side of the display panel 101 which is not the display surface, and the projection of the second circuit board 110 on the plane of the display panel 101 is within the range of the display panel 101. The second circuit board 110 is electrically connected with the first circuit board 102, specifically, the second circuit board 110 is electrically connected with the first sub-circuit board 1021.

[0067] The first circuit board 102 and the second circuit board 110 are both hard circuit boards, and the second circuit board 110 is hard connected with the first sub-circuit board 1021, so that the reliability of the connection is increased. The plane of the first circuit board 102 and the plane of the second circuit board 110 can be close to vertical, so as to be more in line with the shape of the display panel 101.

[0068] In some cases, the second circuit board 110 is directly electrically connected with the first sub-circuit board 1021. In other cases, the first circuit board 102 and the second circuit board 110 can be electrically connected in a plug-in manner, and the display device 100 further comprises a pin header, also known as a Dupont pin, which has a first port and a second port, the first port being electrically connected with the first sub-circuit board 1021, and the second port being electrically connected with the second circuit board 110. By electrically connecting the first sub-circuit board 1021 and the second circuit board 110 through the plurality of hard ports on the pin header, the first sub-circuit board 1021 and the second circuit board 110 can be electrically connected, and the reliability of the connection between the first sub-circuit board 1021 and the second circuit board 110 can be improved.

[0069] Please refer to Figure 10 and Figure 11 , Figure 10 for Figure 9 a zoomed-in view of part C, Figure 11 a second structure schematic diagram of the circuit board of the display device provided by the embodiments of the present application. The second circuit board 110 protrudes from the edge of the display panel 101, and the first sub-circuit board 1021 is away from the side of the display panel 101 and surrounds the second circuit board 110 to form an antenna clearance space 1103, and the antenna assembly 111 is arranged on the second circuit board 110 and is arranged in the antenna clearance space 1103, so as to improve the radiation efficiency of the antenna assembly 111.

[0070] Specifically, please continue to refer to Figure 10 and Figure 11 , the second circuit board 110 comprises a third sub-circuit board 1101 and a fourth sub-circuit board 1102, the third sub-circuit board 1101 is arranged on the side of the display panel 101 which is not the display surface, and the fourth sub-circuit board 1102 protrudes from the edge of the display panel 101, the first sub-circuit board 1021 is connected with the fourth sub-circuit board 1102 and surrounds the fourth sub-circuit board 1102 to form the antenna clearance space 1103, and the antenna assembly 111 is arranged on the fourth sub-circuit board 1102 and arranged in the antenna clearance space 1103. It can be understood that by cooperating the display panel 101, the first circuit board 102 and the second circuit board 110, the antenna clearance space 1103 is formed, which not only guarantees the radiation efficiency of the antenna assembly 111, but also reasonably allocates the space on the first circuit board 102 and the second circuit board 110, and improves the space utilization.

[0071] Among them, please continue to refer to Figure 7The antenna assembly 111 includes a Bluetooth antenna 1111, a first WIFI antenna 1112, and a second WIFI antenna 1113. The first WIFI antenna 1112 and the second WIFI antenna 1113 are respectively arranged on two sides of the Bluetooth antenna 1111.

[0072] The antenna type of the first WIFI antenna 1112 and / or the second WIFI antenna 1113 can be a PIFA (Planar Inverted F-shaped Antenna).

[0073] The antenna type of the Bluetooth antenna 1111 can be a slot antenna or a quarter-microstrip antenna.

[0074] It can be understood that the Bluetooth antenna 1111, the first WIFI antenna 1112, and the second WIFI antenna 1113 can be selected as planar antennas, which have a lower cost than three-dimensional metal antennas.

[0075] In order to improve the zero point depth of the Bluetooth antenna 1111 in the horizontal direction, and to realize isolation between the Bluetooth antenna 1111, the first WIFI antenna 1112, and the second WIFI antenna 1113, the display device 100 further includes a first ground conductive body 112 and a second ground conductive body 113. The first ground conductive body 112 and the second ground conductive body 113 are both arranged on the second circuit board 110. The first ground conductive body 112 is arranged between the first WIFI antenna 1112 and the Bluetooth antenna 1111, and the second ground conductive body 113 is arranged between the second WIFI antenna 1113 and the Bluetooth antenna 1111. That is, the first ground conductive body 112 and the second ground conductive body 113 are respectively arranged on two sides of the Bluetooth antenna 1111, which can improve the isolation between the Bluetooth antenna 1111, the first WIFI antenna 1112, and the second WIFI antenna 1113.

[0076] The display device 100 further includes a power supply circuit, an interface circuit, or a signal processing circuit, which are arranged on the second circuit board 110.

The first sub-circuit board 1021 is slightly farther away from the user than the second sub-circuit board 1022, and the acoustic component 106 carried on the second sub-circuit board 1022 can receive voice instructions from the user. Since the first sub-circuit board 1021 and the second sub-circuit board 1022 are arranged in sequence along the thickness direction of the display panel 101, the structure in the thickness direction is overlapped, and the user visually considers that the second sub-circuit board 1022 is hidden in the first sub-circuit board 1021, which is beneficial to the narrow frame effect of the display device 100, and thus improves the appearance of the display device 100.
