In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0041] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0042] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0043] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0049] FIG1 is a block diagram of an electronic device according to some embodiments.

[0050] Referring to FIG. 1 , some embodiments of the present disclosure provide an electronic device 200 .

[0051] Exemplarily, the electronic device 200 can be any display device that displays images, whether in motion (e.g., video) or fixed (e.g., still images), and whether text or images. More specifically, it is expected that the display device of the embodiments described can be implemented in or associated with a variety of electronic devices, such as (but not limited to) mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, camcorders, game consoles, watches, clocks, calculators, television monitors, flat-panel displays, computer monitors, automotive displays (e.g., odometer displays, etc.), navigation systems, cockpit controls and / or displays, displays of camera views (e.g., displays of rearview cameras in vehicles), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., displays of images of a piece of jewelry), etc.

[0052] The electronic device 200 includes at least one electronic device 100 .

[0053] In some examples, the electronic device 200 may include one electronic device 100. It is understood that in other examples, the electronic device may include multiple electronic devices 100, and the multiple electronic devices 100 are cascaded so that adjacent electronic devices 100 are electrically connected to form the electronic device 200.

[0054] In some embodiments, the electronic device 200 is a spliced ​​screen formed by multiple electronic devices 100 .

[0055] The following description will be made by taking the electronic device 200 as a spliced ​​screen as an example:

[0056] FIG. 2 is a structural diagram of an electronic device according to some embodiments.

[0057] Referring to FIG. 2 , some embodiments of the present disclosure provide an electronic device 100 .

[0058] In some examples, the electronic device 100 can be an OLED (Organic Light Emitting Diode) electronic device, a QLED (Quantum Dot Light Emitting Diodes) electronic device, or a micro LED (including MiniLED or MicroLED, LED is a light emitting diode) electronic device.

[0059] Please continue to refer to Figure 2. The electronic device 100 includes a first wireless receiving device 30. The electronic device 100 can use the first wireless receiving device 30 provided therein to receive a code value from a remote control, and send a second signal containing the code value to the control chip of the electronic device 100, so that the electronic device 100 receives the second signal containing the code value, which facilitates other modules within the electronic device 100 to decode the second signal to drive the electronic device 100.

[0060] In some examples, the first wireless receiving device 30 may be an infrared receiving device. Based on this, the infrared receiving device can be used to receive the infrared code value sent from the remote control. However, some embodiments of the present disclosure are not limited to this.

[0061] The inventors of the present disclosure have discovered that, because the first wireless receiving device 30 is disposed within the electronic device 100, the model of the first wireless receiving device 30 is fixed after the electronic device 100 is manufactured, resulting in low adaptability of the electronic device 100. Furthermore, if the first wireless receiving device 30 malfunctions, such as damage, it is difficult to replace, resulting in a short lifespan of the electronic device 100.

[0062] In some embodiments of the present disclosure, the electronic device 100 further includes a first connector 40 , a data detection module 10 , and a data selector 20 .

[0063] A first connector 40 is provided in the electronic device 100 , wherein the first connector 40 includes a first output end 41 of the first connector 40 and a second output end 42 of the first connector 40 .

[0064] The second output terminal 42 of the first connector 40 is electrically connected to the data selector 20. The second output terminal 42 of the first connector 40 is configured to send the code value received from the remote control to the data selector 20 and send the first signal containing the code value to the data selector 20.

[0065] The first output end 41 of the first connector 40 is electrically connected to the data detection module 10. The first output end 41 of the first connector 40 is configured to output a first voltage signal to the data detection module 10 when the input end 43 of the first connector 40 is not left floating.

[0066] In some examples, when the input terminal 43 of the first connector 40 is not suspended, it can be understood that the input terminal 43 of the first connector 40 is electrically connected to another device, which may be a second wireless receiving device or a signal line.

[0067] The following is an example of the input terminal 43 of the first connector and the second wireless receiving device:

[0068] In some examples, the input end 43 of the first connector 40 can be located on the side of the electronic device 100, so that other second wireless receiving devices can use the first connector 40 to be electrically connected to the electronic device 100, so that the electronic device 100 can use the second wireless receiving device electrically connected to the first connector 40 to receive the code value from the remote control to control the electronic device 100.

[0069] Since the second wireless receiving device is not an integrated device within the electronic device 100 but an external independent device, a matching second wireless receiving device can be selected according to the model of the remote control required by the electronic device 100 and electrically connected to the input end 43 of the first connector 40, so that the electronic device 200 can use the second wireless receiving device to receive the code value from the remote control.

[0070] Based on this, the model of the second wireless receiving device can be freely selected according to the model of the remote control, which can help improve the adaptability of the electronic device 200. In addition, when the first wireless receiving device 30 integrated in the electronic device 100 is damaged or fails, another second wireless receiving device can be directly connected via the first connector 40 to replace the first wireless receiving device, thereby extending the life of the electronic device 100.

[0071] In some examples, the first connector 40 may be a jack interface. For example, the first connector 40 may be a 3.5 mm jack interface. However, some embodiments of the present disclosure are not limited to this.

[0072] However, since the first connector 40 is provided in the electronic device 100 and the first connector 40 is electrically connected to the second wireless receiving device, the electronic device 200 can receive the code value received from the first wireless receiving device 30 inside the electronic device 200, and can also receive the code value received from the second wireless receiving device outside the electronic device 200. At this time, the electronic device 100 can receive two code values, which makes it easy for the electronic device 100 to cause misprocessing.

[0073] Based on this, a data detection module 10 and a data selector 20 may be provided in the electronic device 100 .

[0074] The data detection module 10 is electrically connected to the first output terminal 41 of the first connector 40 and receives a first voltage signal from the first output terminal 41 of the first connector 40. The data detection module 10 is configured to generate a control signal under the control of the first voltage signal from the first output terminal 41 of the first connector 40. Furthermore, the data detection module 10 is also electrically connected to the data selector 20 and is configured to transmit the generated control signal to the data selector 20.

[0075] The data selector 20 includes a first input terminal 21 , a second input terminal 22 and a control terminal 23 .

[0076] The first input terminal 21 of the data selector 20 is electrically connected to the second output terminal 42 of the first connector 40 , and receives the first signal (the first signal including the code value) from the first connector 40 .

[0077] The second input terminal 22 of the data selector 20 is electrically connected to the first wireless receiving device 30 to receive the second signal (the second signal including the code value) from the first wireless receiving device 30 .

[0078] The control terminal 23 of the data selector 20 is electrically connected to the data detection module 10 and receives a control signal from the data detection module 10 .

[0079] As shown in the above structure, when the input terminal 43 of the first connector 40 is not left floating, the control signal received from the data detection module 10 is a first level signal. The data selector 20 is configured such that, under the control of the low level signal from the data detection module 10, the output terminal 24 of the data selector 20 outputs the first signal received via the first input terminal 21 of the data selector 20.

[0080] When the input terminal 43 of the first connector 40 is left floating, the control signal received from the data detection module 10 is a second-level signal. The data selector 20 is configured such that, under the control of the low-level signal from the data detection module 10, the output terminal 24 of the data selector 20 outputs the second signal received via the second input terminal 22 of the data selector 20.

[0081] That is, the data detection module 10 and the data selector 20 can be used in conjunction with each other in the electronic device 100, and a priority is set in the data selector 20. When the input end 43 of the first connector 40 is not left floating, that is, the input end 43 of the first connector 40 is electrically connected to other devices, for example, when the input end 43 of the first connector 40 is electrically connected to the second wireless receiving device, the first output end 41 of the first connector 40 controls the data detection module 10 to output a control signal (first level signal) to the data selector 20, so that the data selector 20 gives priority to outputting the first signal from the first connector 40 and ignores the second signal from the first wireless receiving device 30, so as to prevent the electronic device 100 from receiving two code values ​​(the first signal and the second signal) and prevent the electronic device 100 from misprocessing.

[0082] In summary, the electronic device 100 provided in some embodiments of the present disclosure includes a data detection module 10, a data selector 20, a first wireless receiving device 30, and a first connector 40. The electronic device 100 is equipped with a first connector 40, so as to utilize the first connector 40 to electrically connect a second wireless receiving device outside the electronic device 100, so that the electronic device 100 can also utilize the second wireless receiving device to receive a code value from a remote control. In addition, when the data detection module 10 and the data selector 20 are coordinated, a priority is set in the data selector 20. When the input terminal 43 of the first connector 40 is not left floating, the data detection module 10 controls the output terminal 24 of the data selector 20 to preferentially output the first signal from the first connector 40, and ignores the second signal from the first wireless receiving device 30, so as to prevent the electronic device 100 from receiving two code values ​​(the first signal and the second signal) and prevent the electronic device 100 from misprocessing.

[0083] Furthermore, if the first wireless receiving device 30 integrated within the electronic device 100 is not damaged, the input terminal 43 of the first connector 40 can be left floating, that is, the first connector 40 is not connected to the second wireless receiving device. In this case, the data detection module 10 controls the output terminal 24 of the data selector 20 to preferentially output the second signal from the first wireless receiving device 30. The control chip within the electronic device 100 can decode the second signal to drive the electronic device 100.

[0084] Furthermore, since the second wireless receiving device is externally connected to the first connector 40 of the electronic device 100, it is easy to remove and replace, which can help improve the compatibility of the electronic device 200. Furthermore, if the first wireless receiving device 30 integrated within the electronic device 100 is damaged or fails, another second wireless receiving device can be directly connected to the first connector 40 to replace the first wireless receiving device, thereby extending the life of the electronic device 100.

[0085] In some implementations, the environment in which the electronic device 100 exists may also include other devices with wireless receiving devices. Based on this, within a certain angle and distance range, when driving other devices with wireless receiving devices, the wireless receiving device in the electronic device 100 may malfunction, receiving signals from the remote control driving the other devices with wireless receiving devices, and thus causing the electronic device 100 to malfunction.

[0086] Furthermore, in some embodiments, as shown in FIG. 2 , the code value received from the remote control by the second wireless receiving device electrically connected to the first connector 40 of the electronic device 100 may be a code value with an identifier. Alternatively, the code value received from the remote control by the first wireless receiving device 30 may be a code value with an identifier. This identifier may be set to match the identifier information of the target electronic device 100 to be controlled by the remote control.

[0087] Based on this, after receiving the code value with the identifier, the electronic device 100 can use the control chip of the electronic device 100 to decode the first signal containing the code value with the identifier, or decode the second signal containing the code value with the identifier to obtain the corresponding identification bit. If the identification bit obtained after decoding matches the identification information of the target electronic device 100, the data obtained by decoding the first signal or the second signal can drive the target electronic device 100, which can help achieve directional control and prevent crosstalk problems.

[0088] FIG3 is a structural diagram of an electronic device according to some other embodiments.

[0089] In some embodiments, referring to FIG. 3 , the data detection module 10 includes a first transistor T1 and a first power supply terminal VCC1 .

[0090] The control electrode a1 of the first transistor T1 is electrically connected to the first output terminal 41 of the first connector 40, and the first electrode b1 of the first transistor T1 is electrically connected to the first output terminal 41 of the first connector 40, and the second electrode c1 of the first transistor T1, the first power supply terminal VCC1 and the control terminal 23 of the data selector 20 are electrically connected to the same first node N1.

[0091] The control electrode a1 of the first transistor T1 and the first electrode b1 of the first transistor T1 are both electrically connected to the first output terminal 41 of the first connector 40 .

[0092] When the input terminal 43 of the first connector 40 is not suspended, the first connector 40 is configured such that the first output terminal 41 of the first connector 40 outputs a first voltage signal to the control electrode a1 of the first transistor T1 and the first electrode b1 of the first transistor T1 in the data detection module 10. The first voltage signal is a first level signal.

[0093] At this time, the control electrode a1 of the first transistor T1 receives the first level signal from the first connector 40, controlling the first transistor T1 to turn on. The first level signal received from the first connector 40 at the first electrode b1 of the first transistor T1 can be transmitted to the first node N1 through the second electrode c1 of the first transistor T1. At this time, in the data detection module 10, the first level signal output at the first node N1 is transmitted as a control signal to the control terminal 23 of the data selector 20.

[0094] Based on this, the data selector 20 can, based on the control signal (first level signal), preferentially output the first signal from the first connector 40 and ignore the second signal from the first wireless receiving device 30, thereby preventing the electronic device 100 from receiving two code values ​​(first signal and second signal) and preventing the electronic device 100 from misprocessing.

[0095] When the input terminal 43 of the first connector 40 is left floating, the first connector 40 is configured such that the first output terminal 41 of the first connector 40 outputs a first voltage signal to the control electrode a1 of the first transistor T1 and the first electrode b1 of the first transistor T1 in the data detection module 10. The first voltage signal is a second level signal.

[0096] At this point, the control electrode a1 of the first transistor T1 receives the second-level signal from the first connector 40, turning off the first transistor T1. The first electrode b1 of the first transistor T1 is in a floating state, and the second-level signal from the first connector 40 cannot be transmitted to the first node N1. However, the second-level signal provided by the first power supply terminal VCC1 can be transmitted to the first node N1. At this point, in the data detection module 10, the second-level signal output at the first node N1 is transmitted as a control signal to the control terminal 23 of the data selector 20.

[0097] Based on this, the data selector 20 can preferentially output the second signal from the first wireless receiving device 30 based on the control signal (second level signal), and the control chip in the electronic device 100 can decode the second signal to drive the electronic device 100 .

[0098] In some examples, the first level signal is a low level signal, the second level signal is a high level signal, and the first transistor T1 is a P-type transistor.

[0099] When the first transistor T1 is a P-type transistor, the control electrode a1 of the first transistor T1 is turned on when receiving a low-level signal, and is turned on when receiving a high-level signal.

[0100] Based on this, when the input terminal 43 of the first connector 40 is not left floating, the first output terminal 41 of the first connector 40 outputs a low-level signal to the control terminal a1 of the first transistor T1 and the first terminal b1 of the first transistor T1. The control terminal a1 of the first transistor T1 receives the low-level signal, turning on the first transistor T1. This allows the low-level signal at the first terminal b1 of the first transistor T1 to be transmitted to the first node N1. The data detection module 10 transmits the low-level signal as a control signal to the control terminal 23 of the data selector 20. Upon receiving the low-level signal, the data selector 20 prioritizes outputting the first signal from the first connector 40.

[0101] When the input terminal 43 of the first connector 40 is left floating, the first output terminal 41 of the first connector 40 outputs a high-level signal to the control terminal a1 of the first transistor T1 and the first terminal b1 of the first transistor T1. The control terminal a1 of the first transistor T1 receives the high-level signal, turning off the first transistor T1. The first terminal b1 of the first transistor T1 is left floating, and the high-level signal from the first connector 40 cannot be transmitted to the first node N1. However, the high-level signal provided by the first power supply terminal VCC1 can be transmitted to the first node N1. The data detection module 10 transmits the high-level signal as a control signal to the control terminal 23 of the data selector 20. The data selector 20 receives the high-level signal and preferentially outputs the second signal from the first wireless receiving device 30.

[0102] In some examples, in the standby state of the electronic device 100 , the first power terminal VCC1 may provide a high level signal.

[0103] In some examples, the first power supply terminal VCC1 can be a power supply terminal specifically for the data detection module. The value of the second level signal provided by the first power supply terminal VCC1 can be adjusted as needed. However, the present disclosure is not limited thereto, and the first power supply terminal VCC1 can also reuse a power supply terminal already present in the electronic device 100.

[0104] In some embodiments, referring to FIG3 , the data detection module 10 further includes a first protection unit R1 connected in series between the first node N1 and the first power supply terminal VCC. The first protection unit R1 can provide current limiting and stable protection.

[0105] In some examples, the first protection unit R1 includes a resistor. For example, the first protection unit R1 may be a pull-up resistor.

[0106] Specifically, by using the first connector 40 , and cooperating with the first protection unit R1 and the first power supply terminal VCC1 , the first node N1 can maintain a low potential signal when the first transistor T1 is turned on; and maintain a high potential signal when the first transistor T1 is turned off.

[0107] In some examples, the first protection unit R1 may be a 0402 precision resistor with a resistance accuracy of 5%. However, some embodiments of the present disclosure are not limited thereto.

[0108] In some embodiments, referring to FIG. 3 , the data detection module 10 further includes a second protection unit R2 connected in series between the first output terminal 41 of the first connector 40 and the first electrode b1 of the first transistor T1. The data detection module 10 further includes a ground terminal GND. The ground terminal GND, the second protection unit R2, and the first transistor T1 are electrically connected to the same second node N2. The second protection unit R2 can provide current limiting and stable protection.

[0109] In some examples, the second protection unit R2 includes a resistor. For example, the second protection unit R2 can be a pull-down resistor.

[0110] Specifically, by using the first connector 40 , in conjunction with the second protection unit R2 and the ground terminal GND, the first node N1 can maintain a low potential signal when the first transistor T1 is turned on; and maintain a high potential signal when the first transistor T1 is turned off.

[0111] In some examples, the second protection unit R2 may be a 0402 precision resistor with a resistance accuracy of 5%. However, some embodiments of the present disclosure are not limited thereto.

The control chip 50 is configured to receive the first signal or the second signal from the data selector 20 and interpret it as a data signal to drive the electronic device 100.

[0114] The first connector, the data detection module 10, and the data selector 20 cooperate to control the data selector 20 to output the first signal from the first connector 40 or the second signal from the first wireless receiving device 30. Furthermore, the data selector 20 transmits the first signal or the second signal to the control chip 50. The control chip 50 can decode the first signal or the second signal and use the decoded data to drive the electronic device.

[0118] The decoding unit 51 is electrically connected to the output terminal 24 of the data selector 20 and is configured to decode the first signal or the second signal to obtain the first data. The decoding unit 51 is also electrically connected to the software layer data processing definition unit 52 and is configured to receive the first data from the decoding unit 51 and transmit the first data to the software layer data processing definition unit 52.

[0119] The software layer data processing definition unit 52 is electrically connected to the decoding unit 51 and the output unit 53. The software layer data processing definition unit 52 is configured to receive the first data from the decoding unit 51 and generate a first instruction. The software layer data processing definition unit 52 then outputs the first instruction via the output unit 53 to drive the electronic device 100.

[0120] In some examples, as shown in FIG5 , when the code value received by the second wireless receiving device electrically connected to the first connector 40 from the remote controller is a code value with an identifier, or when the code value received by the first wireless receiving device 30 from the remote controller is a code value with an identifier, and the electronic device 100 has its identifier information:

[0121] The decoding unit 51 is configured to decode the first signal or the second signal, obtain the first data and the identifier, and send the first data and the identifier obtained by decoding to the software layer data processing definition unit 52 .

[0122] The software layer data processing definition unit 52 stores the identification information of the electronic device 100, and receives the first data and identification from the decoding unit 51. If the identification matches the identification information of the target electronic device 100, the software layer data processing definition unit 52 can generate a first instruction based on the first data and send it to the output unit 53 to drive the target electronic device 100.

[0123] Based on this, the electronic device 100 can implement directional operation based on the received code value with the identifier, preventing other devices with wireless receiving devices from generating crosstalk on the electronic device 100, which can help reduce the probability of the electronic device 100 appearing.

[0129] The control electrode a2 of the second transistor T2 is electrically connected to the second power supply terminal VCC2 , the first electrode b2 of the second transistor T2 is electrically connected to the output terminal 24 of the data selector 20 , and the second electrode c2 of the second transistor T2 is electrically connected to the control chip 50 .

[0130] Based on this, the control electrode a2 of the second transistor T2 can receive a power signal from the second power supply terminal VCC2 to control the second transistor T2 to turn on. At this time, the output terminal 24 of the data selector 20 and the control chip 50 are normally electrically connected, that is, the data selector 20 can send the first signal or the second signal to the control chip 50.

[0131] When the electronic device 100 is in standby mode, the second power supply terminal VCC2 is turned off and can no longer provide a power signal. At this time, the control electrode a2 of the second transistor T2 does not receive a power signal, and the second transistor T2 can be controlled to be in an off state, thereby disconnecting the output terminal 24 of the data selector 20 and the control chip 50, so as to achieve low power consumption of the electronic device 100.

[0132] In some embodiments, the second power supply terminal VCC2 can be reused as a system power supply terminal in the electronic device 100.

[0138] FIG9 is a structural diagram of an electronic device according to yet other embodiments.

[0139] 9 , the electronic device 100 further includes a second connector 70 . An input terminal 71 of the second connector 70 is electrically connected to the output terminal 24 of the data selector 20 .

[0140] Based on this, the output terminal 24 of the data selector 20 can be electrically connected to the control chip 50 and the second connector 70 respectively. That is, when the data selector 20 outputs the first signal or the second signal to the control chip 50, the data selector 20 can also output the first signal or the second signal to the second connector 70.

[0141] In this case, the electronic device 100 includes both a first connector 40 and a second connector 70. The first connector 40 acts as an input connector in the electronic device 100, and the second connector 70 acts as an output connector in the electronic device 100. In other words, the electronic device 100 can use the first connector 40 to connect to a second wireless receiving device or signal line to receive signals; and the electronic device 100 can use the second connector 70 to output signals to other devices.

[0142] Furthermore, the electronic device 100 can be electrically connected to other devices using the second connector 70.

[0144] In some embodiments, referring to FIG. 10 , the electronic device 100 further includes a second switch unit 80 . The second switch unit 80 is connected in series between the output terminal 24 of the data selector 20 and the second connector 70 .

[0145] A second switch unit 80 is provided between the output end 24 of the data selector 20 and the second connector 70. The second switch unit 80 can be used to disconnect the output end 24 of the data selector 20 and the second connector 70 when the electronic device 100 is in standby mode, so as to achieve low power consumption of the electronic device 100.

[0146] FIG11 is a structural diagram of an electronic device according to yet other embodiments.

[0147] 11 , the electronic device 100 further includes a second switch unit 80 connected in series between the output terminal 24 of the data selector 20 and the second connector 70. The second switch unit 80 includes a third transistor T3 and a third power supply terminal VCC3.

[0148] The control electrode a3 of the second transistor T2 is electrically connected to the third power supply terminal VCC3 , the first electrode b3 of the third transistor T3 is electrically connected to the output terminal 24 of the data selector 20 , and the second electrode c3 of the third transistor T3 is electrically connected to the input terminal 71 of the second connector 70 .

[0149] Based on this, the control electrode a3 of the third transistor T3 can receive a power signal from the third power supply terminal VCC3 to control the third transistor T3 to turn on. At this time, the output terminal 24 of the data selector 20 and the second connector 70 are normally electrically connected, that is, the data selector 20 can send the first signal or the second signal to the second connector 70.

[0150] When the electronic device 100 is in standby mode, the third power supply terminal VCC3 is turned off and can no longer provide a power signal. At this time, the control electrode a3 of the third transistor T3 does not receive a power signal, and the third transistor T3 can be controlled to be in an off state, thereby disconnecting the output terminal 24 of the data selector 20 and the second connector 70, so as to achieve low power consumption of the electronic device 100.

[0151] In some embodiments, the third power terminal VCC3 can be reused as a system power terminal in the electronic device 100. Furthermore, when the electronic device 100 is in a standby state, the third power terminal VCC3 can be turned off and no longer provide a power signal to control the connection between the output terminal 24 of the data selector 20 and the second connector 70.

[0152] In some embodiments, please continue to refer to FIG. 11 , the electronic device 100 includes a first switch unit 60 and a second switch unit 80 .

[0153] The second power supply terminal VCC2 in the first switch unit 60 and the third power supply terminal VCC3 in the second switch unit 80 may be the same system power supply terminal.

[0154] When the electronic device 100 is in standby mode, the system power supply terminals (the second power supply terminal VCC2 and the third power supply terminal VCC3) are shut down and can no longer provide power signals. At this point, the second transistor T2 in the first switch unit 60 and the third transistor T3 in the second switch unit 80 are both turned off. This disconnects the output terminal 24 of the data selector 20 from the control chip 50 and the second connector 70, thereby reducing power consumption of the electronic device 100 in standby mode.

[0155] FIG12 is a structural diagram of an electronic device according to yet other embodiments.

[0156] In some embodiments, referring to FIG. 12 , the electronic device 100 further includes an amplifier 90 . The amplifier 90 is connected in series between the input terminal 71 of the second connector 70 and the output terminal 24 of the data selector 20 .

[0157] When driving the electronic device 100 and other devices simultaneously, the second connector 70 of the electronic device 100 can be used to electrically connect the other devices. This allows the first signal or the second signal output by the data selector 20 of the electronic device 100 to be transmitted to the control chip 50 of the electronic device 100 and then to be further transmitted to the other devices via the second connector 70 to drive the other devices.

[0158] Based on this, an amplifier 90 is provided between the input end 71 of the second connector 70 and the output end 24 of the data selector 20. The amplifier 90 can amplify the first signal or the second signal before the data selector 20 outputs the first signal or the second signal to the second connector 70, so as to compensate for the loss of the first signal or the second signal during the transmission process, so that other devices electrically connected to the second connector 70 can receive the amplified first signal or the second signal and drive normally, thereby preventing the first signal or the second signal from being lost during the transmission process and being unable to drive other devices electrically connected to the second connector 70.

[0159] FIG13 is a structural diagram of an electronic device according to yet other embodiments.

[0160] In some embodiments, when the electronic device 100 further includes a second switching unit 80 and an amplifier 90:

[0161] The first method: As shown in FIG13 , the amplifier 90 is connected in series between the second connector 70 and the second switch unit 80. Therefore, when the electronic device 100 is in standby mode and the second switch unit 80 is closed, the amplifier 90 cannot receive the first signal or the second signal output by the data selector 20 and does not need to amplify them, thereby reducing the power consumption of the electronic device 100 in standby mode.

[0162] Second: the amplifier 90 may also be connected in series between the second switch unit 80 and the data selector 20. However, some embodiments of the present disclosure are not limited to this.

[0163] FIG14 is a structural diagram of an electronic device according to yet other embodiments.

[0164] 14 , the first connector 40 in the electronic device 100 further includes a first power port 44 and a second power port 45. The first power port 44 can be electrically connected to the fourth power terminal VCC4, and the second power terminal 45 is electrically connected to the ground terminal GND.

[0165] Based on this, the first connector 40 can be electrically connected to the fourth power terminal VCC4 and the ground terminal GND, so that the first connector 40 works.

[0166] In addition, the fourth power supply terminal VCC4 can be used to make the first power port 44 a high potential, and the first power port 44 can be electrically connected to the first output terminal 41, so that when the input terminal 43 of the first connector 40 is suspended, the first voltage signal output by the first output terminal 41 in the first connector 40 can be a high-level signal.

[0167] In some examples, the fourth power terminal VCC4 may be a power terminal dedicated to the first connector 40. The power level provided by the fourth power terminal VCC4 may be adjusted as needed. However, the present disclosure is not limited thereto, and the fourth power terminal VCC4 may also reuse a power terminal already present in the electronic device 100.

[0168] In some embodiments, referring to FIG. 14 , the data selector 20 in the electronic device 100 further includes a third power port 25 and a fourth power port 26 .

[0169] The third power port 25 is electrically connected to the ground terminal GND, and the fourth power port 26 is electrically connected to the first capacitor C1. The fourth power port 26 is a high-level power port. The first capacitor C1 is also electrically connected to the ground terminal GND. Therefore, the first capacitor C1 can be used to filter the data selector 20, ensuring normal operation.

[0170] In some examples, as shown in FIG. 14 , the electronic device 100 may further connect a third protection unit R3 in series between the second input terminal 22 of the data selector 20 and the second output terminal 42 of the first connector 40 . The third protection unit R3 may be utilized to improve the stability of the potential outputted from the second input terminal 22 of the data selector 20 .

[0171] In some examples, the third protection unit R3 may be a 0402 precision resistor with a resistance accuracy of 5%. However, some embodiments of the present disclosure are not limited thereto.

[0172] In some embodiments, referring to FIG14 , the electronic device 100 may further include a pull-up unit 110. The pull-up unit 110 includes a fourth resistor R4 and a fifth power supply terminal VCC5.

[0173] In some examples, a pull-up unit 110 may be provided between the second connector 70 and the second switch unit 80, so that the fourth resistor R4, the input terminal 71 of the second connector 70, and the second electrode c3 of the third transistor T3 in the second switch unit 80 are electrically connected to the same node, so that the pull-up unit 110 can be used to stabilize the potential of the input terminal 71 of the second connector 70 and the second electrode c3 of the third transistor T3, and to protect the circuit.

[0174] In some examples, a pull-up unit 110 can be provided between the data selector 20 and the first switching unit 60, so that the fourth resistor R4, the output terminal 24 of the data selector 20 and the first electrode b2 of the second transistor T2 are electrically connected to the same node, so that the pull-up unit 110 can be used to stabilize the potential of the first electrode b2 of the second transistor T2 and serve as a protection circuit.

[0175] In some examples, the fourth resistor R4 may be a 0402 precision resistor with a resistance accuracy of 5%. However, some embodiments of the present disclosure are not limited thereto.

[0176] In some examples, the fourth power terminal VCC4 may be a power terminal dedicated to the first connector 40. The power level provided by the fourth power terminal VCC4 may be adjusted as needed. However, the present disclosure is not limited thereto, and the fourth power terminal VCC4 may also reuse a power terminal already present in the electronic device 100.

[0177] In some examples, the fourth power terminal VCC4 and the fifth power terminal VCC5 can be the same power terminal. This configuration reduces the number of used power terminals, can help save space inside the electronic device 100, and can facilitate the connection and arrangement of wiring inside the electronic device 100.

[0178] In some embodiments, as shown in FIG14 , the electronic device 100 may further include a fifth resistor R5. The fifth resistor R5 is connected in series between the output terminal 24 of the data selector 20 and the first electrode b3 of the third transistor T3. The fifth resistor R5 is also connected in series between the first electrode b3 of the third transistor T3 and the control chip 50.

[0179] The fifth resistor R5 can be used to stabilize the circuit to prevent excessive signal between the first electrode b3 of the third transistor T3 and the data selector 20 and the control chip 50, thereby affecting circuit quality.

[0180] In some examples, the fifth resistor R5 may be a 0402 precision resistor with a resistance accuracy of 5%. However, some embodiments of the present disclosure are not limited thereto.

[0181] FIG15 is a structural diagram of an electronic device according to some other embodiments.

[0182] 15 , in some embodiments, the electronic device 200 includes a second wireless receiving component 210 and an electronic apparatus 100 . The second wireless receiving component 210 can be electrically connected to the input terminal 43 of the first connector 40 .

[0183] At this time, the electronic device 200 includes the second wireless receiving device 210 and the first wireless receiving device 30 in the electronic apparatus 100. Furthermore, the electronic device 200 can use the first wireless receiving device 30 and the second wireless receiving device 210 in the electronic apparatus 100 to receive the code value from the remote controller.

[0184] The second wireless receiving device 210 can receive a code value from the remote controller, and transmit a first signal containing the code value to the data selector 20 through the first connector 40 .

[0185] The first wireless receiving device 30 can receive the code value from the remote controller and transmit the second signal containing the code value to the data selector 20 .

[0186] Furthermore, since the second wireless receiving device 210 is electrically connected to the input terminal 43 of the first connector 40, the input terminal 43 of the first connector 40 is not floating. The first output terminal 41 of the first connector 40 can output a first voltage signal to the data detection module 10. In this case, the first voltage signal is a first level signal. The first level signal output by the data detection module serves as a control signal and is transmitted to the control terminal 23 of the data selector 20. Based on this control signal (first level signal), the data selector 20 can prioritize outputting the first signal from the first connector 40 and ignoring the second signal from the first wireless receiving device 30. This prevents the electronic device 100 from receiving two code values ​​(the first signal and the second signal), thereby preventing erroneous processing by the electronic device 100.

[0187] In summary, when the second wireless receiving device 210 is electrically connected to the input terminal 43 of the first connector 40 in the electronic device 200, the electronic device 100 in the electronic device 200 prioritizes processing the code value received by the second wireless receiving device 210 to drive the electronic device 200. Furthermore, because the second wireless receiving device 210 and the first connector 40 are independent components, the desired second wireless receiving device 210 can be freely selected and electrically connected to the first connector 40 in the electronic device 100. This improves the compatibility between the electronic device 100 and the electronic device 200. Furthermore, if the first wireless receiving device 30 in the electronic device 100 malfunctions, the second wireless receiving device 210 can be used to replace the first wireless receiving device 30, thereby improving the service life of the electronic device 100 and the electronic device 200.

[0188] In some examples, the second wireless receiving device 210 may be an infrared receiving device. Based on this, the infrared receiving device can be used to receive the infrared code value sent from the remote control. However, some embodiments of the present disclosure are not limited to this.

[0189] FIG16 is a structural diagram of an electronic device according to yet other embodiments.

[0190] In some embodiments, as shown in FIG16 , the electronic device 200 includes a plurality of electronic devices 100. The distances between the electronic devices 100 in the electronic device 200 are relatively close. When driving a target electronic device 100 in the electronic device 200, it is easy for other electronic devices near the target electronic device 100 to also receive the signal sent by the remote control, which can easily lead to malfunction of the electronic device 100. Moreover, when driving multiple electronic devices 100 in the electronic device 200, due to the different distances between each electronic device 100 and the remote control, the signal receiving capabilities are different, which can cause the electronic device 200 to be unable to drive multiple electronic devices 100 at the same time, resulting in low efficiency in the use of the electronic device 200.

[0191] The electronic device 200 in some embodiments of the present disclosure may include a second wireless receiving device 210 and multiple cascaded electronic devices 100. The electronic device 100 includes a second connector 70, and an input terminal 71 of the second connector 70 is electrically connected to the output terminal 24 of the data selector 20.

[0192] In a plurality of cascaded electronic devices 100, the input end 43 of the first connector 40 in the first electronic device 101 is electrically connected to the second wireless receiving device 210. In two adjacent electronic devices 100, the input end 43 of the first connector 40 in the lower electronic device 100 is electrically connected to the output end 72 of the second connector 70 in the upper electronic device.

[0193] Take a target electronic device 100 in the driving electronic device 100 as an example for description:

[0194] A target electronic device is selected from all cascaded electronic devices, and identification information of the target electronic device is obtained.

[0195] The input terminals 43 of the first connectors 40 of the multiple electronic devices 100 in the electronic device 200 are not in a floating state, and thus the data selectors 20 in each electronic device 100 preferably output signals from the first connector 40 .

[0196] Furthermore, since the first connector in the lower electronic device 100 can be electrically connected to the data selector 20 in the upper electronic device using the output end 72 of the second connector 70 in the upper electronic device, the first connector 40 in the lower electronic device 100 can receive the first signal output by the data selector 20 in the upper electronic device. Thus, the first signal can be transmitted to the other electronic devices step by step using the first electronic device 101.

[0197] After each electronic device 100 obtains the first signal, the control chip 50 in each electronic device 100 obtains the identification information of its own device. If the identification information matches the identification carried by the first signal, it indicates that the electronic device 100 is the target electronic device. At this time, the control chip 50 in the electronic device 100 parses the first signal, obtains the first data, and drives the target electronic device. If the identification information does not match the identification carried by the first signal, it indicates that the electronic device 100 is not the target electronic device. At this time, the control chip 50 in the electronic device 100 cannot obtain the data of the electronic device 100 based on the first signal. Furthermore, the code value in the first signal and the identification information of the electronic device can also be used to effectively prevent the problem of mutual crosstalk among the electronic devices 100 in the electronic device 200, thereby reducing the probability of malfunction of the electronic device 100.

[0198] Take two adjacent electronic devices 100, namely a first electronic device 101 and a second electronic device 102, as an example for description:

[0199] In the first electronic device 101:

[0200] The second wireless receiving device 210 can receive a code value with an identifier from the remote control and transmit the first signal containing the code value to the data selector 20 via the first connector 40. The identifier contained in the code value matches the identifier information of the target electronic device, meaning that the first signal carries an identifier that matches the identifier information of the target electronic device.

[0201] The first wireless receiving device 30 can receive a code value with an identifier from the remote control and transmit a second signal containing the code value to the data selector 20. The identifier contained in the code value matches the identifier information of the target electronic device, meaning that the second signal carries an identifier that matches the identifier information of the target electronic device.

[0202] In some examples, the identification information of the electronic device includes a serial number of the electronic device. However, some embodiments of the present disclosure are not limited thereto.

[0203] Furthermore, since the second wireless receiving device 210 is electrically connected to the input terminal 43 of the first connector 40, the input terminal 43 of the first connector 40 in the first electronic device 101 is not in a floating state. The first output terminal 41 of the first connector 40 can output a first voltage signal to the data detection module 10. In this case, the first voltage signal is a first level signal. The first level signal output by the data detection module serves as a control signal and is transmitted to the control terminal 23 of the data selector 20. Based on this control signal (first level signal), the data selector 20 can preferentially output the first signal from the first connector 40 to the control chip 50 and the second connector 70 in the first electronic device 101.

[0204] The control chip 50 in the first electronic device 101 may obtain identification information of the first electronic device 101. For example, the identification information of the first electronic device 101 may include a serial number "1".

[0205] When the identification information of the first electronic device 101 obtained by the control chip 50 in the first electronic device 101 matches the identification information of the first electronic device 101 carried by the first signal, it indicates that the first electronic device 101 is the target electronic device. At this time, the control chip 50 in the first electronic device 101 analyzes the first signal, obtains the first data, and drives the target electronic device (the first electronic device 101).

[0206] If the identification information of the first electronic device 101 obtained by the control chip 50 in the first electronic device 101 does not match the identification information carried by the first signal, it indicates that the first electronic device 101 is not the target electronic device. In this case, the control chip 50 in the first electronic device 101 cannot obtain data that can drive the first electronic device 101 based on the first signal.

[0207] At this time, the data selector 20 can output the first signal to the second connector 70 , and transmit the first signal to the next-level electronic device (the second electronic device 102 ) via the second connector 70 .

[0208] In the second electronic device 102:

[0209] The first connector 40 may transmit the first signal from the first electronic device 101 to the data selector 20 .

[0210] Furthermore, the first wireless receiving device 30 can receive a code value with an identifier from the remote controller, and transmit the second signal containing the code value to the data selector 20 .

[0211] Since the second connector 70 in the first electronic device 101 is electrically connected to the first connector 40 in the second electronic device 102, for example, the second connector 70 in the first electronic device 101 can be electrically connected to the first connector 40 in the second electronic device 102 using a signal line L.

[0212] Based on this, the input terminal 43 of the first connector 40 in the second electronic device 102 is also not in a floating state. The first output terminal 41 of the first connector 40 can output a first voltage signal to the data detection module 10. In this case, the first voltage signal is a first level signal. The first level signal output by the data detection module serves as a control signal and is transmitted to the control terminal 23 of the data selector 20. Based on this control signal (first level signal), the data selector 20 can preferentially output the first signal from the first connector 40 to the control chip 50 and the second connector 70 in the second electronic device 102.

[0213] The control chip 50 in the second electronic device 102 may obtain identification information of the second electronic device 102. For example, the identification information of the second electronic device 102 may include a serial number "2".

[0214] When the identification information of the second electronic device 102 obtained by the control chip 50 in the second electronic device 102 matches the identification information of the first signal, it indicates that the second electronic device 102 is the target electronic device. At this time, the control chip 50 in the second electronic device 102 analyzes the first signal, obtains the first data, and drives the target electronic device (the second electronic device 102).

[0215] If the identification information of the second electronic device 102 obtained by the control chip 50 in the second electronic device 102 does not match the identification information carried by the first signal, it indicates that the second electronic device 102 is not the target electronic device. In this case, the control chip 50 in the second electronic device 102 cannot obtain data that can drive the second electronic device 102 based on the first signal.

[0216] At this time, the second connector 70 in the second electronic device 102 can be used to continue transmitting the first signal to the next-level electronic device (the third electronic device 103), and the first signal can be continued to be transmitted downward level by level, so that all electronic devices 100 in the electronic device 200 can receive the first signal, and can determine whether the identification information of their own devices matches the identification carried by the first signal. Only the matching electronic device 100 can be driven according to the first signal, and thus only the target electronic device in the electronic device 200 can be driven according to the first signal.

[0217] Among them, the working principles of the electronic devices 100 in the electronic device 200 except the first electronic device 101 are roughly the same as the working principle of the second electronic device 102 mentioned above, and the working principle of the second electronic device 102 can be referred to the above description, which will not be repeated here.

[0218] Taking driving multiple electronic devices 100 in an electronic device 100 as an example, the following is described:

[0219] Among all the cascaded electronic devices, a plurality of electronic devices are selected as target electronic devices.

[0220] The input terminals 43 of the first connectors 40 of the multiple electronic devices 100 in the electronic device 200 are not in a floating state, and thus the data selectors 20 in each electronic device 100 preferably output signals from the first connector 40 .

[0221] Furthermore, since the first connector in the lower electronic device 100 can be electrically connected to the data selector 20 in the upper electronic device using the output end 72 of the second connector 70 in the upper electronic device, the first connector 40 in the lower electronic device 100 can receive the first signal output by the data selector 20 in the upper electronic device. Thus, the first signal can be transmitted to the other electronic devices step by step using the first electronic device 101.

[0222] After each electronic device 100 obtains the first signal, the control chip 50 in each electronic device 100 decodes the first signal, obtains the first data, and drives the target electronic device, thereby achieving unified driving of multiple electronic devices 100 in the electronic device 200 .

[0223] After decoding the first signal, the control chip 50 can obtain the first data and the identification bit contained in the first signal. In this case, the identification bit can be a preset identification bit, such as "0", "all", or "*", which has no practical meaning, or the identification information in each electronic device 100 can be matched with it, so that the first data after decoding the first signal can drive the target electronic device.

[0224] Take two adjacent electronic devices 100, namely a first electronic device 101 and a second electronic device 102, as an example for description:

[0225] In the first electronic device 101:

[0226] The second wireless receiving device 210 can receive a code value with an identifier from the remote control and transmit the first signal containing the code value to the data selector 20 via the first connector 40. The identifier in the code value can be a preset identifier, such as "0", "all", or "*", which has no practical meaning, or the identifier information in each electronic device 100 can be matched with it.

[0227] The first wireless receiving device 30 can receive the code value with the identifier from the remote control and transmit the second signal containing the code value to the data selector 20. The identifier in the code value can be a preset identifier, such as "0", "all", or "*", which has no practical meaning, or the identifier information in each electronic device 100 can be matched with it.

[0228] Furthermore, since the second wireless receiving device 210 is electrically connected to the input terminal 43 of the first connector 40, the input terminal 43 of the first connector 40 in the first electronic device 101 is not in a floating state. The first output terminal 41 of the first connector 40 can output a first voltage signal to the data detection module 10. In this case, the first voltage signal is a first level signal. The first level signal output by the data detection module serves as a control signal and is transmitted to the control terminal 23 of the data selector 20. Based on this control signal (first level signal), the data selector 20 can preferentially output the first signal from the first connector 40 to the control chip 50 and the second connector 70 in the first electronic device 101.

[0229] The control chip 50 in the first electronic device 101 analyzes the first signal, obtains the first data, and drives the first electronic device 101 .

[0230] The second connector 70 can transmit the first signal to the next-stage electronic device (the second electronic device 102 ). That is, the first connector 40 can transmit the first signal from the first electronic device 101 to the data selector 20 .

[0231] Furthermore, the first wireless receiving device 30 can receive a code value with an identifier from the remote controller, and transmit the second signal containing the code value to the data selector 20 .

[0232] Since the second connector 70 in the first electronic device 101 is electrically connected to the first connector 40 in the second electronic device 102, for example, the second connector 70 in the first electronic device 101 can be electrically connected to the first connector 40 in the second electronic device 102 using a signal line L.

[0233] Based on this, the input terminal 43 of the first connector 40 in the second electronic device 102 is also not in a floating state. The first output terminal 41 of the first connector 40 can output a first voltage signal to the data detection module 10. In this case, the first voltage signal is a first level signal. The first level signal output by the data detection module serves as a control signal and is transmitted to the control terminal 23 of the data selector 20. Based on this control signal (first level signal), the data selector 20 can preferentially output the first signal from the first connector 40 to the control chip 50 and the second connector 70 in the second electronic device 102.

[0234] The control chip 50 in the second electronic device 102 analyzes the first signal, obtains the first data, and drives the second electronic device 102 .

[0235] Furthermore, the first signal can be transmitted to the next-level electronic device (the third electronic device 103) using the second connector 70 in the second electronic device 102, and the first signal can be transmitted downward one level at a time, so that all electronic devices 100 in the electronic device 200 can receive the first signal, analyze the first signal to obtain the first data, and drive each electronic device 100. In this way, multiple electronic devices in the electronic device 200 can be driven uniformly, improving the driving efficiency and accuracy of the electronic device 200.

[0236] Among them, the working principles of the electronic devices 100 in the electronic device 200 except the first electronic device 101 are roughly the same as the working principle of the second electronic device 102 mentioned above, and the working principle of the second electronic device 102 can be referred to the above description, which will not be repeated here.

[0237] In summary, when the second wireless receiving device 210 is provided in the electronic device 200 and electrically connected to the input terminal 43 of the first connector 40, and the second connector 70 in the upper-level electronic device 100 and the first connector 40 in the lower-level electronic device 100 are used to achieve cascading, so that the input terminal 43 of the first connector 40 in each electronic device 100 is not suspended, and then the electronic device 100 in the electronic device 200 prioritizes the code value received by the second wireless receiving device 210 to drive the electronic device 200. In addition, the code value can also be used to carry an identifier to achieve directional control of the target electronic device in the electronic device 200, preventing other electronic devices 100 in the electronic device 200 from having no touch problems. In addition, the cascade structure and the code value with a special identifier can also be used to achieve unified driving of multiple electronic devices in the electronic device 200, thereby improving the driving efficiency and accuracy of the sub-device 200.

[0238] Furthermore, because the second wireless receiving device 210 and the first connector 40 are independent components, the desired second wireless receiving device 210 can be freely selected and electrically connected to the first connector 40 in the electronic device 100. This can further improve the compatibility between the electronic device 100 and the electronic device 200. Furthermore, if the first wireless receiving device 30 in the electronic device 100 is damaged or malfunctions, the second wireless receiving device 210 can be used to replace the first wireless receiving device 30, thereby improving the service life of the electronic device 100 and the electronic device 200.

[0239] FIG17 is a flowchart of a method for controlling an electronic device according to some embodiments.

[0240] Some embodiments of the present disclosure provide a method for controlling an electronic device, wherein the electronic device 200 may be the electronic device described in FIG. 15 or FIG. 16 . The specific structure may refer to the description of the structure of the electronic device 200 in any of the above embodiments, and will not be repeated here. The control chip 50 in the electronic device 100 includes a first working state. When the electronic device 200 needs to drive multiple electronic devices 100 within the electronic device 200, the control chip 50 adopts the first working state.

[0241] Referring to FIG. 17 , the control method includes:

[0242] S1: The first wireless receiving device 30 receives a code value with an identifier from a remote controller, and transmits a second signal containing the code value to the data selector 20.

[0243] S2: The second wireless receiving device 210 receives the code value with the identifier from the remote controller, and transmits the first signal containing the code value to the data selector 20 through the first connector 40 .

[0244] S3: The data detection module 10 receives the first voltage signal from the first output terminal of the first connector 40 and transmits the control signal to the data selector 20. The control signal is a first level signal.

[0245] In the plurality of cascaded electronic devices 100, the input end 43 of the first connector 40 of the first electronic device 101 is electrically connected to the second wireless receiving device 210. Furthermore, in two adjacent electronic devices 100, the input end 43 of the first connector 40 in the next electronic device 100 is electrically connected to the output end 72 of the second connector 70 in the previous electronic device.

[0246] Based on this, the input terminals 43 of the first connectors 40 of the plurality of electronic devices 100 in the electronic device 200 can be in a non-suspended state, and the first output terminals 41 of the first connectors 40 can output a first voltage signal to the data detection module 10, wherein the first voltage signal is a first level signal. The first level signal output by the data detection module 10 is transmitted as a control signal to the control terminal 23 of the data selector 20.

[0247] S4 : the data selector 20 sends the first signal to the control chip 50 based on the first level signal, and sends the first signal to the second connector 70 .

[0248] Based on the control signal (first level signal), the data selector 20 can prioritize outputting the first signal from the first connector 40 and ignore the second signal from the first wireless receiving device 30. Based on this, the data selector 20 can transmit the first signal to the control chip 50 and the second connector 70.

[0249] S5 : In the first working state, the control chip 50 analyzes the first signal, obtains the first data, and drives the target electronic device 100 .

[0250] After decoding the first signal, the control chip 50 can obtain the first data and the identification bit contained in the first signal. In this case, the identification bit can be a preset identification bit, such as "0," "all," or "*," which has no practical meaning. The control chip 50 can ignore the preset identification bit and use the first data obtained from decoding the first signal to drive the target electronic device.

[0251] Based on this, each electronic device 100 is based on a digital structure, and the data selector 20 in the electronic device 100 sends the first signal to the control chip 50. The control chip 50 in each electronic device 100 decodes the first signal, ignores the identification bit in the first signal, and uses the first data obtained from the first signal to drive the target electronic device, thereby achieving unified driving of multiple electronic devices 100 in the electronic device 200.

[0252] For example, the decoding unit 51 in the control chip 50 can parse the first signal, obtain the first data and the identifier, ignore the identifier, and send the first data to the software layer data processing definition unit 52 in the control chip 50. The software layer data processing definition unit 52 in the control chip 50 can generate a first instruction based on the first data and send it to the output unit 53 to drive the target electronic device 100.

[0253] Therefore, the electronic device 200 can utilize the cascade structure and the code value of the special identifier to achieve unified driving of multiple electronic devices in the electronic device 200, thereby improving the driving efficiency and accuracy of the sub-device 200.

[0254] In some other embodiments, the control chip 50 in the electronic device 100 includes a second working state. When the electronic device 200 needs to drive a target electronic device in the electronic device 200, the control chip 50 adopts the second working state.

[0255] In step S5 : in the second working state, the identification information of the electronic device 100 is obtained. If the identification information matches the identification of the code value in the first signal, the control chip 50 parses the first signal, obtains the first data, and drives the target electronic device.

[0256] If the identification information matches the identification carried by the first signal, it indicates that the electronic device 100 is the target electronic device. At this time, the control chip 50 in the electronic device 100 analyzes the first signal, obtains the first data, and drives the target electronic device.

[0257] Exemplarily, the decoding unit 51 in the control chip 50 can parse the first signal to obtain the first data and identification. If the identification matches the identification information of the target electronic device 100, the software layer data processing definition unit 52 in the control chip 50 can generate a first instruction based on the first data and send it to the output unit 53 to drive the target electronic device 100.

[0258] If the identification information does not match the identification carried by the first signal, it indicates that the electronic device 100 is not the target electronic device. In this case, the control chip 50 in the electronic device 100 cannot obtain data of the electronic device 100 based on the first signal.

[0259] Exemplarily, the decoding unit 51 in the control chip 50 can parse the first signal to obtain the first data and identification. If the identification does not match the identification information of the target electronic device 100, the software layer data processing definition unit 52 in the control chip 50 cannot generate the first instruction based on the first data, and thus cannot use the first instruction to drive the target electronic device 100.

[0260] Based on this, the electronic device 100 can implement directional operation based on the received code value with the identifier, preventing other devices with wireless receiving devices from generating crosstalk on the electronic device 100, which can help reduce the probability of the electronic device 100 appearing.

[0261] In some embodiments, please continue to refer to FIG. 17 , the control method further includes obtaining identification information of each electronic device 100 .

[0262] In some examples, the control method may obtain identification information of each electronic device 100 before step S1.

[0263] In two adjacent electronic devices 100:

[0264] The control chip 50 of the electronic device 100 at the upper level obtains the identification information of the electronic device 100 at the upper level, and sends the identification information of the electronic device 100 at the upper level to the electronic device 100 at the lower level via the second connector 70;

[0265] The control chip 50 of the next-level electronic device 100 receives identification information of the previous-level electronic device 100 from the previous-level electronic device 100, and obtains identification information of the next-level electronic device 100; the identification information of the previous-level electronic device 100 is different from the identification information of the next-level electronic device 100.

[0266] After multiple electronic devices 100 are cascaded in the electronic device 200, the control chip 50 in the first electronic device 101 (referring to FIG. 16 ) can be controlled to generate identification information for the first electronic device 101. Furthermore, the control chip 50 in the first electronic device 101 can send the identification information of the first electronic device 101 to the second connector 70 in the first electronic device 101. The second connector 70 of the first electronic device 101 then transmits the identification information of the first electronic device 101 to the first connector 40 in the next-level electronic device (the second electronic device 102).

[0267] The second output terminal 42 of the first connector 40 in the second electronic device 102 can send the identification information of the first electronic device 101 to the second input terminal 22 of the data selector 20. Moreover, since the input terminal of the first connector 40 of the second electronic device 102 is not left floating, the data detection module 10 controls the data selector 20 to output the identification information of the first electronic device 101 received from the first connector 40 at the second input terminal of the data selector 20. Furthermore, the data selector 20 in the second electronic device 102 outputs the identification information of the first electronic device 101 to the control chip 50 in the second electronic device 102. The control chip 50 in the second electronic device 102 receives the identification information of the first electronic device 101, modifies the identification information of the first electronic device 101 to obtain identification information different from the identification information of the first electronic device 101, and uses the identification information as the identification information of the second electronic device 102.

[0268] Moreover, the second electronic device 102 is consistent with the same electronic device 101, and the identification information of the second electronic device 102 can be transmitted to the next-level electronic device (the third electronic device) through the second connector 70 in the second electronic device 102, and the identification information can be passed to other electronic devices 200 one level at a time, so that each electronic device in the electronic device 200 can obtain its unique identification information.

[0269] In summary, multiple electronic devices 100 can be cascaded in an electronic device 200, and based on the cascaded structure of multiple electronic devices 100, unique identification information of each electronic device 100 can be automatically obtained, so that the identification information can be used to distinguish between the electronic devices 100 in the electronic device 200. This facilitates the subsequent use of this information in conjunction with the identification contained in the code value sent by the remote control to achieve directional control and reduce the problem of crosstalk in the electronic device 200.

[0270] In some examples, except for the first electronic device 100 in the electronic device 200, the control chip in other electronic devices 100 can receive the identification information of the previous electronic device 100 and add "1" to it to obtain new identification information that is different from the identification information of the previous electronic device 100.

[0271] For example, the identification information of the first electronic device 100 is 1. When the identification information "1" of the first electronic device 101 is transmitted to the second electronic device 102, the control chip 50 of the second electronic device 102 receives "1" and adds "1" to it, obtaining new identification information "2". At this time, the identification information "2" is used as the identification information of the second electronic device 102. In other words, between two adjacent electronic devices 100, the identification information of the electronic device 100 at the lower level can be the identification information of the electronic device at the upper level + 1.

[0272] However, the present disclosure is not limited thereto. It is understandable that the identification information of each electronic device may also be multi-bit binary data, and in two adjacent electronic devices 100, the identification information of the lower-level electronic device 100 may be obtained by shifting the identification information of the upper-level electronic device.

[0273] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
