[0038] The display includes multiple interfaces, such as a video interface and a transmission interface. Figure 1 As shown, taking the Mini Led display 200 as an example, the display 200 includes an HDMI (High Definition Multimedia Interface) interface, a DP (DisplayPort) interface, a Type-C interface, a Type-B interface and a Type-A interface (USB-A interface), etc., wherein the HDMI interface and the DP interface are used to transmit video signals so that the display can display, and the Type-C interface and the Type-A interface are used for transmission to external devices.

[0039] Usually, the overall power consumption of the display is high when working, and a lot of heat is generated, which causes the temperature to rise and affects the normal operation of the device. Under the condition of meeting the temperature rise, it is a great challenge to achieve simultaneous transmission of the Type-C interface and the Type-A interface, and to enable both the Type-C interface and the Type-A interface to transmit at the appropriate transmission power according to customer needs. In the related technology, the maximum transmission power of the Type-C interface and the Type-A interface is met at the same time by increasing the power supply of the display, but this will cause excessive energy consumption and generate excessive heat, affecting the normal operation of the display.

[0040] Based on this, some embodiments of the present disclosure provide an electrical signal transmission system 100, an electrical signal transmission control chip 1 and a transmission method. The electrical signal transmission system 100 can be applied to electronic devices, such as the display 200 mentioned above. The electrical signal transmission system 100 includes an electrical signal transmission control chip 1, and the transmission method is applied to the electrical signal transmission system 100.

[0041] like Figure 2As shown, in some embodiments, the electrical signal transmission system 100 includes an electrical signal transmission control chip 1, at least two first transmission interfaces 2 and at least one second transmission interface 3, wherein the at least two first transmission interfaces 2 are coupled to the electrical signal transmission control chip 1 and configured to be coupled to a first transmission line for transmission; exemplarily, the external device connected to the first transmission interface 2 through the first transmission line is a mouse, a keyboard, a mobile phone, etc. The second transmission interface 3 is coupled to the electrical signal transmission control chip 1 and configured to be coupled to a second transmission line for transmission, exemplarily, the external device connected to the second transmission interface 3 through the second transmission line is a personal computer, etc. At least two first transmission interfaces 2 and at least one second transmission interface 3 are transmitted at a preset power under the control of the electrical signal transmission control chip 1.

[0042] Exemplarily, the electrical signal transmission system 100 is applied to a display, such as Figure 1 As shown, the display 200 includes a display mainboard 20, on which an electrical signal transmission control chip 1, at least two first transmission interfaces 2 and at least one second transmission interface 3 are all arranged. The electrical signal transmission system 100 also includes a power interface 8.

[0043] In some embodiments, the first transmission interface 2 and the second transmission interface 2 can realize the function of transmitting electrical signals, for example, the first transmission interface 2 and the second transmission interface 2 can realize power transmission and realize external charging function, or the first transmission interface 2 and the second transmission interface 2 can also transmit data signals, video signals, etc. Exemplarily, when the external device connected to the second transmission interface 3 is a personal computer, the second transmission interface 3 can transmit the video signal input by the personal computer, so that the display can display the picture.

[0044] like Figure 2As shown, the electrical signal transmission system 100 includes, for example, four first transmission interfaces 2 and one second transmission interface 3, the first transmission interface 2 is, for example, a Type-A interface, the first transmission line is a Type-A line, the second transmission interface 3 is, for example, a Type-C interface, and the second transmission line is a Type-C line. Among them, among at least two first transmission interfaces 2, one of the first transmission interfaces 2 is a fast transmission interface 22, and the other first transmission interfaces 2 are ordinary transmission interfaces 21. Exemplarily, one of the four first transmission interfaces 2 is a fast transmission interface 22, for example, the interface is a Type-A interface of USB 3.0, and the maximum transmission power of the fast transmission interface 22 is 5V / 2.5A. When the third transmission mode is turned on (the third transmission mode controls the turning on and off of the fast transmission function of the fast transmission interface 22), the BC1.2 fast transmission function can be realized. When the third transmission mode is turned off, the fast transmission interface 22 cannot realize the fast transmission function, and its maximum transmission power is consistent with the maximum transmission power of the ordinary transmission interface 21. The other three first transmission interfaces 2 are ordinary transmission interfaces 21, and their maximum transmission power is 5V / 0.9A. The second transmission interface 3, namely the Type-C interface, supports large current and high voltage transmission. On the premise that the second transmission line connected to the second transmission interface 3 supports the fast transmission mode, for example, the second transmission line supports PD3.0, 5A, the Type-C interface can transmit at a larger power (for example, 90W). Otherwise, the maximum transmission power of the Type-C interface has an upper limit, for example, 60W (20V / 3A).

[0045] In the electrical signal transmission method provided in some embodiments of the present disclosure, three transmission modes are involved, that is, the electrical signal transmission mode of the electrical signal transmission system includes three transmission modes, namely, a first transmission mode, a second transmission mode and a third transmission mode, wherein the first transmission mode is, when the at least two first transmission interfaces 2 and the second transmission interface 3 are used at the same time, the total transmission power of the at least two first transmission interfaces 2 and the second transmission interface 3 is less than the first preset power. It can be understood that the system reasonably configures the transmission power of the second transmission interface 3 according to the transmission power of the at least two first transmission interfaces 2 while maintaining the first preset power so that the total transmission power of the at least two first transmission interfaces 2 and the second transmission interface 3 does not exceed the first preset power. Exemplarily, the first preset power is the maximum output power of the electrical signal transmission system 100 during transmission, and the first preset power is, for example, 100W.

[0046] It should be noted that the situation in which at least two first transmission interfaces 2 are used includes that all first transmission interfaces 2 are connected to external devices and are used, or that some of the at least two first transmission interfaces 2 are used, for example, two of the four first transmission interfaces 2 are connected to external devices for transmission.

[0047] The second transmission mode is used to control the opening or closing of the fast transmission function of the second transmission interface 3. Since the second transmission interface 3 is a Type-C interface, it supports high current and high voltage transmission. When the second transmission mode is turned on, the second transmission interface 3 can transmit to the outside at full load. For example, the maximum transmission power of the second transmission interface 3 can reach the first preset power of 100W; when the second transmission mode is turned off, the transmission power of the second transmission interface 3 depends on the situation.

[0048] It is understandable that the first transmission mode and the second transmission mode cannot be enabled at the same time.

[0049] The third transmission mode is used to control the opening or closing of the fast transmission function of the fast transmission interface 22 in at least two first transmission interfaces 2. Taking the electrical signal transmission system 100 including four first transmission interfaces 2, and one of the first transmission interfaces 2 being the fast transmission interface 22 as an example, when the third transmission mode is turned on, the fast transmission function of the fast transmission interface 22 in the four first transmission interfaces 2 is turned on, and the transmission is performed with the maximum transmission power being the fourth preset power, and the remaining three ordinary transmission interfaces 21 are transmitted with the maximum transmission power being the third preset power, and the fourth preset power is greater than the third preset power, for example, the fourth preset power is 12.5W (5V / 2.5A), and the third preset power is 4.5W (5V / 0.9A). When the third transmission mode is turned off, the fast transmission function of the fast transmission interface 22 in the four first transmission interfaces 2 is turned off, and the four first transmission interfaces 2 are all transmitted with the maximum transmission power being the third preset power, for example, the third preset power is 4.5W (5V / 0.9A).

[0050] It is understandable that the first transmission mode and the third transmission mode can be enabled at the same time.

[0051] like Figure 4A to Figure 4C As shown, the display can display an OSD (on-screen display, screen menu adjustment mode) interface, and the OSD interface 1-1 includes a first transmission mode option, a second transmission mode option and a third transmission mode option. Each option has an on button and a off button. Clicking the corresponding button can turn on the corresponding transmission mode. For example, Figure 4BAs shown, the operation of opening the first transmission mode is that the user clicks the opening button of the first transmission mode option, and the electrical signal transmission control chip 1 in the electrical signal transmission system 100 responds to the instruction of the first transmission mode and controls the first transmission interface 2 and the second transmission interface 3 to transmit in the first transmission mode. The operation of opening the second transmission mode is that the user clicks the opening button of the second transmission mode option, and the electrical signal transmission control chip 1 responds to the instruction of opening the second transmission mode and controls the first transmission interface 2 and the second transmission interface 3 to transmit in the second transmission mode. The operation of opening the third transmission mode is that the user clicks the opening button of the third transmission mode option, and the electrical signal transmission control chip 1 responds to the instruction of opening the third transmission mode and controls the first transmission interface 2 and the second transmission interface 3 to transmit in the third transmission mode.

[0052] In addition, the OSD interface 1-1 also includes a transmission power display bar of the second transmission interface 3, in which the transmission power value of the second transmission interface 3 is displayed. Figure 4A As shown, the transmission power display bar of the second transmission interface 3 displays a power value of 90W.

[0053] The following introduces the electrical signal transmission method provided by some embodiments of the present disclosure. The following is an example in which the electrical signal transmission system 100 includes four first transmission interfaces 2 and one second transmission interface 3, and the first transmission interface 2 is a Type-A interface and the second transmission interface 3 is a Type-C interface.

[0054] It should be noted that in the electrical signal transmission method provided in some embodiments of the present disclosure, the priority of the first transmission interface 2 is higher than the priority of the second transmission interface 3, that is, when the total power of the system is constant, the first transmission interface 2 is given priority to transmit electrical signals, and then the transmission power of the second transmission interface 3 is considered to be set according to the corresponding transmission mode.

[0055] like Figure 6 As shown, the method includes:

[0056] When at least two first transmission interfaces 2 and second transmission interfaces 3 are used at the same time, determine whether the second transmission mode is turned on; if so, make the first transmission mode function invalid, and respond to the instruction to turn on the second transmission mode, make the maximum transmission power of the second transmission interface the first preset power; if not, determine whether the first transmission mode is turned on.

[0057] Determine whether the first transmission mode is turned on, and the result is: if so, in response to the instruction to turn on the first transmission mode, the total transmission power of the at least two first transmission interfaces and the second transmission interface is less than or equal to the first preset power; if not, the maximum transmission power of the second transmission interface is set to the second preset power.

[0058] Exemplarily, the second preset power is less than the first preset power.

[0059] Exemplarily, the first preset power is 100W, and the second preset power is 74W.

[0060] In some embodiments, making the total transmission power of at least two first transmission interfaces 2 and the second transmission interface 3 less than a first preset power includes:

[0061] Read in real time the real-time total power of at least two first transmission interfaces 2 during the process of transmitting electrical signals, calculate the transmission power of the second transmission interface 3 according to the real-time total power and the first preset power, and control the second transmission interface 3 to transmit electrical signals in real time according to the calculated transmission power of the second transmission interface 3.

[0062] Exemplarily, the real-time total power during transmission of at least two first transmission interfaces 2 is read every 2 seconds. For example, the real-time power during transmission of each first transmission interface 2 is W1, and the first preset power is W2. Then, when there are at least two first transmission interfaces 2, which are n in number, the transmission power W3 of the second transmission interface 3 is: W3=W2-n*W1.

[0063] For example, if the real-time total power of at least two first transmission interfaces 2 during transmission is 5W, the transmission power of the second transmission interface 3 is calculated to be 95W based on the real-time total power and the first preset power (100W), and the transmission of the second transmission interface 3 is controlled in real time based on the calculated transmission power of the second transmission interface 3. Figure 4B As shown, a value of 95W is displayed in the transmission power display column of the second transmission interface 3.

[0064] When the external device connected to the second transmission interface 3 is a personal computer, the electrical signal transmission system 100 transmits 95W of power to the personal computer, while the personal computer can also control the display used by the electrical signal transmission system 100 to display.

[0065] In some embodiments, the transmission mode of the electrical signal also includes adopting a second transmission mode and a third transmission mode. The method is introduced as an overall example below.

[0066] like Figure 6 As shown, combined with Figure 2 , Figure 4A to Figure 4C , the transmission methods include:

[0067] S1. Determine whether the second transmission interface 3 is connected to the second transmission line.

[0068] Exemplarily, the terminal of the second transmission line is connected to a personal computer, and the second transmission interface 3 is coupled to the personal computer to charge the personal computer, while controlling the display to display through the personal computer.

[0069] For the judgment result of S1, if yes, go to S2, if no, go to S3.

[0070] S2. Determine whether the second transmission line supports the fast transmission mode.

[0071] Exemplarily, it is determined whether the connected second transmission line supports PD3.0, 5A and contains an E-maker (Electronically Marked Cable) chip. The second transmission line containing an E-maker chip means that the second transmission line is an active cable encapsulated with an E-maker chip, and has strong power transmission and data transmission capabilities, so that the second transmission line can support a fast transmission mode, for example, it can support high-power charging.

[0072] S3. Disable the first transmission mode function and the second transmission mode function, and enable the third transmission mode function.

[0073] Both the first transmission mode and the second transmission mode involve the use of the second transmission interface 3. When the second transmission interface 3 is not connected to the second transmission line, the second transmission interface 3 is not used, so the first transmission mode function and the second transmission mode function are invalidated, and the third transmission mode function is valid. The at least two first transmission interfaces 2 can transmit in the third transmission mode.

[0074] Among them, disabling the first transmission mode function and the second transmission mode function means that the system turns off the first transmission mode function and the second transmission mode function, controls at least two first transmission interfaces 2 and second transmission interfaces 3 to be unable to transmit in the first transmission mode and the second transmission mode, and in the OSD interface 1-1, the first transmission mode option and the second transmission mode option are grayed out, and the corresponding on button and off button cannot be selected, and the user cannot turn on the first transmission mode and the second transmission mode. Enabling the third transmission mode function means that the system turns on the third transmission mode function, controls at least two first transmission interfaces 2 and second transmission interfaces 3 to be able to transmit in the third transmission mode, and in the OSD interface 1-1, the third transmission mode option can be selected, and the user can turn on the third transmission mode by clicking the corresponding on button. It should be noted that turning on the first transmission mode function means that the first transmission mode can be selected by the user (in fact, whether the first transmission mode is turned on is unknown), and turning on the first transmission mode means that the system transmits in the first transmission mode.

[0075] For the judgment result of S2, if yes, then go to S4 and S6, if no, then go to S5.

[0076] S4. Disable the first transmission mode function and the second transmission mode function, and enable the third transmission mode function.

[0077] S6. Determine whether the total power consumption of at least two first transmission interfaces 2 exceeds the set power consumption.

[0078] The power consumption value is set to be low, for example, the power consumption is set to 2W. When at least two first transmission interfaces 2 are connected to low-power external devices such as a mouse and keyboard, the total power consumption of at least two first transmission interfaces 2 is low and will not exceed the set power consumption of 2W.

[0079] S5. Enable the first transmission mode function, the second transmission mode function, and the third transmission mode function, and enable the maximum transmission power of the second transmission interface 3 to be less than the fifth transmission power.

[0080] The user can normally select the first transmission mode, the second transmission mode and the third transmission mode as needed. Since the second transmission line does not support the fast transmission mode, the second transmission line is used. The maximum transmission power of the Type-C interface has an upper limit value, and the fifth transmission power is less than the second transmission power. For example, the fifth transmission power is 60W (20V / 3A).

[0081] For the judgment result of S6, if yes, then go to S7, if no, then go to S8 and S9.

[0082] S7, invalidating the second transmission mode function, enabling the first transmission mode function, and in response to an instruction to enable the first transmission mode, making the total transmission power of at least two first transmission interfaces 2 and second transmission interfaces 3 less than or equal to the first preset power.

[0083] If the total power consumption of at least two first transmission interfaces 2 exceeds the set power consumption, for example, the total power consumption of the at least two first transmission interfaces 2 is 40W, the second transmission interface 3 cannot transmit with the first preset power of 100W as the maximum transmission power, so the system automatically turns off the second transmission mode function and turns on the first transmission mode function, so that the total transmission power of the at least two first transmission interfaces 2 and the second transmission interface 3 does not exceed the first preset power. If the total power consumption of at least two first transmission interfaces 2 does not exceed the set power consumption, for example, the total power consumption of the at least two first transmission interfaces 2 is only 1W, the total power consumption can be ignored, and the second transmission interface 3 can transmit with the first preset power of 100W as the maximum transmission power, that is, the second transmission mode function is valid.

[0084] S8. Enable the first transmission mode function, the second transmission mode function and the third transmission mode function.

[0085] S9, judging whether the second transmission mode is turned on, that is, judging whether the user clicks the on button of the second transmission mode option, and whether the electrical signal transmission control chip 1 receives and responds to the instruction to turn on the second transmission mode.

[0086] For the judgment result of S9, if yes, then go to S10; if no, then go to S11 or S14.

[0087] S10: Disable the first transmission mode function, and in response to an instruction to enable the second transmission mode, set the maximum transmission power of the second transmission interface 3 to the first preset power.

[0088] The first transmission mode and the second transmission mode cannot be turned on at the same time. Therefore, when the second transmission mode is turned on, the first transmission mode function is automatically turned off. In the second transmission mode, the maximum transmission power of the second transmission interface 3 is the first preset power, that is, the second transmission interface 3 can transmit with the first preset power of 100W as the maximum transmission power, thereby achieving efficient and fast transmission.

[0089] S11, judging whether the first transmission mode is turned on, that is, judging whether the user clicks the on button of the first transmission mode option, and whether the electrical signal transmission control chip 1 receives and responds to the instruction to turn on the first transmission mode.

[0090] For the judgment result of S11, if yes, then go to S12, if no, then go to S13.

[0091] S12: In response to the instruction to start the first transmission mode, the total transmission power of at least two first transmission interfaces 2 and the second transmission interface 3 is made less than or equal to a first preset power.

[0092] In this step, when at least two first transmission interfaces 2 and second transmission interfaces 3 are used at the same time, the system configures the transmission power of the second transmission interface 3 in real time according to the transmission power of at least two first transmission interfaces 2, thereby simultaneously satisfying that the first transmission interface 2 and the second transmission interface 3 can transmit with appropriate power.

[0093] S13: Set the maximum transmission power of the second transmission interface 3 to a second preset power.

[0094] It should be noted that the maximum transmission power of the second transmission interface 3 is the maximum power that can be output when the second transmission interface 3 is used, and it is not the actual transmission power. The actual transmission power of the second transmission interface 3 may be less than the second preset power. The second preset power is obtained based on the maximum output power that the system can provide during transmission (for example, 100W) and the maximum transmission power of at least two transmission interfaces during transmission. For example, the maximum total transmission power of at least two transmission interfaces during transmission is the total transmission power when all transmission interfaces are used and the fast transmission function of the fast transmission interface 22 is turned on. Taking the at least two transmission interfaces as four Type-A interfaces as an example, the power of three ordinary transmission interfaces 21 is 4.5W (5V / 0.9A), and the power of one fast transmission interface 22 is 12.5W (5V / 2.5A), then the maximum total transmission power of the four Type-A interfaces is 26W, and thus the maximum transmission power of the second transmission interface 3 is 74W. By way of example, the second preset power is 74W.

[0095] S14, judging whether the third transmission mode is turned on, that is, judging whether the user clicks the on button of the third transmission mode option, and whether the electrical signal transmission control chip 1 receives and responds to the instruction to turn on the third transmission mode.

[0096] For the judgment result of S14, if yes, go to S15, if no, go to S16.

[0097] S15, in response to the instruction to turn on the third transmission mode, the maximum transmission power of the fast transmission interface 22 of the at least two first transmission interfaces 2 is set to a third preset power, and the maximum transmission power of the common transmission interface 21 is set to a fourth preset power. The third preset power is greater than the fourth preset power, and illustratively, the third preset power is 4.5 W (5 V / 0.9 A), and the fourth preset power is 12.5 W (5 V / 2.5 A).

[0098] S16: Set the maximum transmission power of each of the at least two first transmission interfaces 2 to be a fourth preset power.

[0099] In summary, the electrical signal transmission method provided by some embodiments of the present disclosure, under the premise of not increasing the maximum output power of the system, by setting three transmission modes, reasonably configures the transmission power of each transmission interface, ensures the maximum transmission power of the first transmission interface 2 and the second transmission interface 3 under different circumstances, and improves the utilization rate of the system power supply. The user can choose to turn on a certain transmission mode through the OSD interface 1-1 in the display, so as to select the corresponding transmission interface according to the demand to transmit with appropriate power, thereby meeting the user's transmission requirements for the first transmission interface 2 and the second transmission interface 3. The use of this electrical signal transmission method will not increase the power consumption of the system, thereby avoiding the problem of excessive power consumption and excessive temperature rise affecting the normal operation of electronic equipment.

[0116] It should be noted that the above-mentioned "coupling" may mean that there is no direct contact between the first power monitor 4 and at least two first transmission interfaces 2, but there is a connection channel, which can form a communication coupling, and still cooperate or interact with each other. The "coupling" between two or more components mentioned below can also be explained by the above content.
