Technical Field

[0002] For existing monitors, no matter what type of device is used to power it, the startup brightness and volume of the monitor after it is powered on, as well as the maximum adjustable brightness and volume, are fixed. However, in actual applications, since different types of power supply devices have different power supplies, existing monitors will have the following problems: 1. When the power supply to the monitor is small, if the startup brightness and volume are set too high, the monitor will not get enough power and will not work properly, and may even damage the power supply device due to excessive load; if the maximum adjustable brightness and volume are too high, when the user turns up the brightness and volume of the monitor, the monitor will also face the problem of insufficient power and cannot work properly; 2. When the power supply to the monitor is large, if the startup brightness and volume are set too low, the user needs to manually adjust the brightness and volume of the monitor, which results in a poor user experience; if the maximum adjustable brightness and volume are too low, the power supply cannot be fully utilized to obtain a higher brightness and volume.

It should be understood that the figure mark also applies to other identical parts or components.

[0056] Embodiment 1

[0057] like Figure 1 FIG. 1 is a flow chart of a control method for a display device provided in an embodiment of the present application; the control method may include the following steps:

[0058] Step 101: The display device is connected to a first power supply device, so that the first power supply device supplies power to the display device, and the display device and the first power supply device can communicate with each other.

[0059] It can be understood that the above-mentioned display device is a USB C display, which can be used as an external display of a laptop computer or as an external display of a mobile phone. When used as an external display of a laptop computer, its first power supply device is the laptop computer, and the power supply power is 7.5W (5V / 1.5A) to 15W (5V / 3A). When used as an external display of a mobile phone, its first power supply device is the mobile phone, and the power supply power is 4.5W (5V / 0.9A) to 7.5W (5V / 1.5A). Of course, a second power supply device can also be connected to the display device for power supply. For example, a USB C power adapter can provide more voltage and greater power for the display device, and the first power supply device connected to the display device can also be charged through a USB C power adapter.

[0060] It should be noted that in the above step 101, the USB C display establishes a connection with the first power supply device through the USB C interface, and the connection line between the USB C interface and the first power supply device can not only meet the power supply of the USB C display by the first power supply device, but also enable protocol communication between the first power supply device and the USB C display.

[0061] Step 102: The display device obtains a first power supply value provided by a first power supply device to the display device.

[0062] Step 103: The display device sets a power-on brightness, a power-on volume, a first maximum adjustable brightness, and a first maximum adjustable volume that match the first power supply value according to the first power supply value.

[0063] It can be understood that different power supply power values ​​indicate different power consumption that the display device can consume. Therefore, the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume of the display device are set to match the power supply power value, so that the power obtained by the display device after powering on is sufficient to meet the power required for the power-on brightness and power-on volume so that it can work normally, and the user does not need to manually adjust the brightness and volume significantly to find the appropriate brightness and volume, and the user experience is very good; the power required for the first maximum adjustable brightness and the first maximum adjustable volume will not exceed the power obtained after the display device is turned on. Therefore, when the user adjusts the brightness and volume, the display device will not only not face the problem of insufficient power and inability to work normally, but can also make full use of the power to obtain greater brightness and louder volume.

[0064] In this embodiment, after the display device is connected to the first power supply device, the first power supply power value provided by the first power supply device is first obtained, and then the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume are set according to the first power supply power value. In this way, the power-on brightness, power-on volume, maximum adjustable brightness and maximum adjustable volume of the display device can all match the first power supply power value, and then the power consumption of the display device can be intelligently adapted to the first power supply power value provided by the first power supply device, which can not only enable the display device to work normally without damaging the first power supply device, but also make full use of the power supply power provided by the first power supply device.

[0065] Embodiment 2

[0066] like Figure 2 As shown, it is another flow chart of a control method of a display device provided in an embodiment of the present application; the control method may include the following steps:

[0067] Step 201: The display device is connected to a first power supply device, so that the first power supply device supplies power to the display device, and the display device and the first power supply device can communicate with each other.

[0068] It should be noted that this step is the same as step 101 in the above-mentioned embodiment 1 and will not be described in detail here.

[0069] Step 202: The display device receives a first power supply voltage value and a first power supply current value sent by a first power supply device to the display device.

[0070] It can be understood that after the display device is connected to the first power supply device, the first power supply device will automatically send its power supply voltage value and power supply current value to the display device. Here, the display device and the first power supply device are connected together by wires, and the wires include power supply wires and communication protocol wires. It should be noted that after the display device is connected to the first power supply device, the first power supply device will first determine whether the display device and the first power supply device are in a connected state. Specifically, the first power supply device detects whether the level of the communication protocol line in the wire connected to it is a high level. If so, it means that the first power supply device is not connected to the display device. If not, it means that the level of the protocol line has changed, which means that the first power supply device and the display device are in a connected state. The first power supply device supplies power to the display device. At this time, the first power supply device will send its power supply voltage value and power supply current value to the display device, otherwise not only will it not send information, but it will not supply power.

[0071] Step 203: The display device obtains a first power supply value provided by the first power supply device to the display device according to the first power supply voltage value and the first power supply current value.

[0072] It should be noted that after the display device receives the first power supply voltage value and the first power supply current value sent by the first power supply device, it can obtain the power supply value of the first power supply device according to the power calculation formula P=UI.

[0073] Step 204: The display device compares the first power supply value with the preset power interval, and uses the power level corresponding to the first preset power interval including the first power supply value as the level of the first power supply value.

[0074] It can be understood that there are two or more preset power intervals mentioned above, and the specific process of comparing the first power supply power value with the preset power intervals can be: comparing the first power supply power value with each preset power interval respectively to obtain a preset power interval containing the first power supply power value; it can also be: first arranging two or more preset power intervals in order from large to small according to the interval endpoint values, where one of the endpoint values ​​of each two adjacent preset power intervals is set to be equal, each preset power interval corresponds to a power level, and the first power supply power value is compared with the preset power intervals in sequence according to the arranged preset power interval order. When the preset power interval containing the first power supply power value is found, it is no longer necessary to compare it with the remaining preset power intervals, thereby improving the efficiency of obtaining the level of the first power supply power, and thus can affect the display device to more quickly set the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume that match the level of the first power supply power value.

[0075] Step 205: The display device sets a power-on brightness, a power-on volume, a first maximum adjustable brightness, and a first maximum adjustable volume that match the level of the first power supply value according to the level of the first power supply value.

[0076] It can be understood that different levels of the first power supply power value indicate different sizes of the first power supply power value, that is, the power consumption that the display device can consume is different. Therefore, the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume of the display device are set to match the level of the first power supply power value, so that the power obtained by the display device after powering on is sufficient to meet the power required for the power-on brightness and power-on volume so that it can work normally, and the user does not need to manually adjust the brightness and volume significantly to find the appropriate brightness and volume, and the user experience is very good; the power required for the first maximum adjustable brightness and the first maximum adjustable volume will not exceed the power obtained after the display device is turned on. Therefore, when the user adjusts the brightness and volume, the display device will not only not face the problem of insufficient power and inability to work normally, but can also make full use of the power to obtain greater brightness and louder volume.

[0077] For example, assume there are 4 preset power ranges, which are greater than or equal to X1, less than X1 and greater than or equal to X2, less than X2 and greater than or equal to X3, and less than X3, and X1 > X2 > X3. The power levels corresponding to the four preset power ranges of greater than or equal to X1, less than X1 and greater than or equal to X2, less than X2 and greater than or equal to X3, and less than X3 are level one, level two, level three, and level four respectively. The display device will first compare the first power supply value with X1 to determine whether the first power supply value ≥ X1. If so, then the level of the first power supply value is set as level one, and the startup brightness is set as y1, the startup volume is set as z1, the first maximum adjustable brightness is set as Y1, and the first maximum adjustable volume is set as Z1; if the power supply value is less than X1, then it continues to determine whether the first power supply value is greater than or equal to X2. If so, it means X2 ≤ the first power supply value < X1, and the level of the first power supply value is set as level two, and the startup brightness is set as y2, the startup volume is set as z2, the first maximum adjustable brightness is set as Y2, and the first maximum adjustable volume is set as Z2; if the power supply value is less than X2, then it continues to determine whether the first power supply value is greater than or equal to X3. If so, it means X3 ≤ the first power supply value < X2, and the level of the first power supply value is set as level three, and the startup brightness is set as y3, the startup volume is set as z3, the first maximum adjustable brightness is set as Y3, and the first maximum adjustable volume is set as Z3; if the first power supply value is less than X3, it means the first power supply value < X3, and the level of the first power supply value is set as level four, and the startup brightness is set as y4, the startup volume is set as z4, the first maximum adjustable brightness is set as Y4, and the first maximum adjustable volume is set as Z4. Figure 4 It is the flowchart for the above work of setting the startup brightness, startup volume, first maximum adjustable brightness, and first maximum adjustable volume.

[0078] Step 206, the display device turns off or on at least one of the speaker, wifi module, and bluetooth module of the display device according to the first power supply value.

[0079] It can be understood that when the first power supply value is relatively large, at least one of the speaker, wifi module, and bluetooth module of the display device can be appropriately turned on. When the first power supply value is relatively small, at least one of the speaker, wifi module, and bluetooth module of the display device can be appropriately turned off, so that the display device can still work normally under a small power supply value. Of course, the modules that are turned on or off here can be other modules in addition to the speaker, wifi module, and bluetooth module. Specifically, which module to turn on or off can be selected by the user. The user can sort the priorities of the various modules of the display device in advance, and then the display device will select which module to turn on or off according to the priorities of the various modules.

[0080] In this embodiment, after the display device is connected to the first power supply device, the first power supply value provided by the first power supply device is first obtained, and then the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume are set according to the first power supply value, so that the power-on brightness, power-on volume, maximum adjustable brightness and maximum adjustable volume of the display device can all match the first power supply value, and then the power consumption of the display device can be intelligently adapted to the first power supply value provided by the first power supply device, which can not only allow the display device to work normally without damaging the first power supply device, but also make full use of the power supply provided by the first power supply device. In addition, at least one of the speaker, wifi module and Bluetooth module of the display device can be turned off or on according to the first power supply value to achieve a balance between the power consumption and function of the display device.

[0081] Embodiment 3

[0082] like Figure 3 As shown, it is another flow chart of a control method of a display device provided in an embodiment of the present application; the control method may include the following steps:

[0083] Step 301: The display device is connected to a first power supply device, so that the first power supply device supplies power to the display device, and the display device and the first power supply device can communicate with each other.

[0084] It should be noted that this step is the same as step 201 in the above-mentioned embodiment 2, and will not be described in detail here.

[0085] Step 302: The display device receives a first power supply voltage value and a first power supply current value sent by a first power supply device to the display device.

[0086] It should be noted that this step is the same as step 202 in the above-mentioned embodiment 2, and will not be described in detail here.

[0087] Step 303: The display device obtains a first power supply value provided by the first power supply device to the display device according to the first power supply voltage value and the first power supply current value.

[0088] It should be noted that this step is the same as step 203 in the above-mentioned embodiment 2, and will not be described in detail here.

[0089] Step 304: The display device compares the first power supply value with the preset power interval, and uses the power level corresponding to the first preset power interval including the first power supply value as the level of the first power supply value.

[0090] It should be noted that this step is the same as step 204 in the above-mentioned embodiment 2, and will not be described in detail here.

[0091] Step 305: The display device sets a power-on brightness, a power-on volume, a first maximum adjustable brightness, and a first maximum adjustable volume that match the level of the first power supply value according to the level of the first power supply value.

[0092] It should be noted that this step is the same as step 205 in the above-mentioned embodiment 2, and will not be described in detail here.

[0093] Step 306: The display device turns off or turns on at least one of a speaker, a wifi module, and a Bluetooth module of the display device according to the first power supply value.

[0094] It should be noted that this step is the same as step 206 in the above-mentioned embodiment 2, and will not be described in detail here.

[0095] Step 307: The display device is further connected to a second power supply device, so that the second power supply device supplies power to the display device, and the display device and the second power supply device can communicate with each other.

[0096] It can be understood that when the first power supply device mentioned above is a mobile phone or a tablet computer, the second power supply device mentioned above can be a power adapter.

[0097] Step 308: When the second power supply device supplies power to the display device, the first power supply device stops supplying power to the display device, and the display device obtains a second power supply value provided by the second power supply device to the display device.

[0098] It should be noted that when the first power supply device is a mobile phone or a laptop computer, and the second power supply device is a power adapter, the display device is first connected to the mobile phone or laptop computer. At this time, the power supply value obtained by the display device is fixed. When the display device is connected to the power adapter again, the mobile phone or laptop computer will stop supplying power to the display device. At this time, the power adapter supplies power to the display device and charges the mobile phone or laptop computer. The power supply process is that the power supply current of the power adapter first passes through the display device and then flows to the mobile phone or laptop computer. Since the display device consumes some power when working, the power supply reaching the mobile phone or laptop computer will become smaller after the power adapter supplies power to the display device. Since the power adapter can supply multiple powers, multiple specifications of power can be input into the mobile phone or laptop computer. At this time, the mobile phone or laptop computer needs to select one of the multiple specifications of power supply, and then the mobile phone or laptop computer sends the selected power supply specification information to the display device. The display device then sends the power supply specification information corresponding to the power supply specification selected by the mobile phone or laptop computer and not yet consumed by the display device to the power adapter. At this time, the power adapter will adjust its supply voltage value and supply current value according to the power supply specification information sent by the display device that is not consumed by the display device, and send it to the display device.

[0099] For example, if the power adapter can provide three power supplies, namely 4.5W (5V / 0.9A), 7.5W (5V / 1.5A), and 15W (5V / 3A), after the power supply current passes through the display device, a part of it is consumed by the display device, and the power supply specification input to the mobile phone or laptop becomes 3.5W (5V / 0.7A), 6.5W (5V / 1.3A), and 14W (5V / 2.8A). At this time, the mobile phone or laptop can choose one of the three power supply specifications. If the mobile phone or If the mobile phone or laptop selects a power supply of 14W (5V / 2.8A), the mobile phone or laptop will send the power supply information of 14W (5V / 2.8A) to the display device, and the display device will send the power supply specification information corresponding to 14W (5V / 2.8A) that is not consumed by the display device, that is, 15W (5V / 3A), to the power adapter, and the power adapter will adjust its supply voltage value to 5V and its supply current value to 3A, and send the adjusted supply voltage value and supply current value to the display device.

[0100] Step 309 : The display device determines whether the second power supply value is equal to the first power supply value; if not, execute step 310 .

[0101] It can be understood that after the display device is connected to the second power supply device, the first power supply device will stop supplying power. In addition to supplying power to the display device, the second power supply device will also charge the first power supply device. Since the second power supply device can supply multiple powers, the second power supply provided by the second power supply device is not necessarily equal to the first power supply power value provided by the first power supply device. Therefore, the display device needs to first determine whether the second power supply power value is equal to the first power supply power value. If they are equal, no operation is performed. If they are not equal, it is necessary to reset the current brightness, current volume, maximum adjustable brightness and maximum adjustable volume to match the current brightness, current volume, maximum adjustable brightness and maximum adjustable volume with the second power supply power value, so that the display device will not face the problem of insufficient power and cannot work normally, and can also make full use of power to obtain greater brightness and louder volume.

[0102] Step 310: The display device sets the current brightness, current volume, second maximum adjustable brightness, and second maximum adjustable volume that match the second power supply value according to the second power supply value.

[0103] It should be noted that this step is the same as the action performed in step 103 in the above-mentioned embodiment 1. In this step, the current brightness, current volume, second maximum adjustable brightness and second maximum adjustable volume that match the second power supply value are set according to the second power supply value. The above-mentioned step 103 is to set the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume that match the first power supply value according to the first power supply value, which will not be repeated here.

[0104] Step 311: The display device turns off or turns on at least one of a speaker, a wifi module, and a Bluetooth module of the display device according to the second power supply value.

[0105] It should be noted that this step is the same as the action performed in the above step 306, and will not be described in detail here.

[0106] In this embodiment, after the display device is connected to the first power supply device, the first power supply value provided by the first power supply device is first obtained, and then the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume are set according to the first power supply value, so that the power-on brightness, power-on volume, maximum adjustable brightness and maximum adjustable volume of the display device can all match the first power supply value, and then the power consumption of the display device can be intelligently adapted to the first power supply value provided by the first power supply device, which can not only allow the display device to work normally without damaging the first power supply device, but also make full use of the power supply provided by the first power supply device. In addition, at least one of the speaker, wifi module and Bluetooth module of the display device can be turned off or on according to the first power supply value to achieve a balance between the power consumption and function of the display device. In addition, after the display device is connected to the second power supply device, the display device re-acquires the second power supply value provided by the second power supply device, and determines whether the second power supply value has changed compared with the first power supply value. If changed, the display device will reset the current brightness, current volume, current maximum adjustable brightness and current maximum adjustable volume according to the second power supply value, so that the power consumption of the display device can intelligently adapt to the second power supply value provided by the second power supply device in real time.

[0107] Embodiment 4

[0108] like Figure 5 As shown, it is another flow chart of a control method of a display device provided in an embodiment of the present application; the control method may include the following steps:

[0109] Step 401: The display device is connected to a first power supply device, so that the first power supply device supplies power to the display device, and the display device and the first power supply device can communicate with each other.

[0110] It should be noted that this step is the same as step 201 in the above-mentioned embodiment 2, and will not be described in detail here.

[0111] Step 402: The display device receives a first power supply voltage value and a first power supply current value sent by a first power supply device to the display device.

[0112] It should be noted that this step is the same as step 202 in the above-mentioned embodiment 2, and will not be described in detail here.

[0113] Step 403: The display device obtains a first power supply value provided by the first power supply device to the display device according to the first power supply voltage value and the first power supply current value.

[0114] It should be noted that this step is the same as step 203 in the above-mentioned embodiment 2, and will not be described in detail here.

[0115] Step 404: The display device compares the first power supply value with the preset power interval, and uses the power level corresponding to the first preset power interval including the first power supply value as the level of the first power supply value.

[0116] It should be noted that this step is the same as step 204 in the above-mentioned embodiment 2, and will not be described in detail here.

[0117] Step 405: The display device sets a power-on brightness, a power-on volume, a first maximum adjustable brightness, and a first maximum adjustable volume that match the level of the first power supply value according to the level of the first power supply value.

[0118] It should be noted that this step is the same as step 205 in the above-mentioned embodiment 2, and will not be described in detail here.

[0119] Step 406: The display device turns off or turns on at least one of a speaker, a wifi module, and a Bluetooth module of the display device according to the first power supply value.

[0120] It should be noted that this step is the same as step 206 in the above-mentioned embodiment 2, and will not be described in detail here.

[0121] Step 407: The display device is also connected to a second power supply device, and the display device and the second power supply device can communicate with each other, and the first power supply device supplies power to the second power supply device and the display device at the same time.

[0122] It can be understood that the second power supply device mentioned above can be a mobile phone or a tablet computer, and the first power supply device is a power adapter.

[0123] Step 408: When the first power supply device supplies power to the second power supply device and the display device at the same time, the display device obtains a second power supply value provided by the first power supply device to the display device.

[0124] It should be noted that when the first power supply device is a power adapter and the second power supply device is a mobile phone or a laptop computer, the display device is first connected to the power adapter. When the display device is then connected to the mobile phone or the laptop computer, since the power adapter can provide a variety of power values ​​and the power adapter provides a greater power value than the mobile phone or the laptop computer, the power adapter will continue to power the display device and charge the mobile phone or the laptop computer at the same time. The power supply process is that the power supply current of the power adapter first passes through the display device and then flows to the mobile phone or the laptop computer. Since the display device consumes some power when it works, the power adapter supplies power to the display device before reaching the mobile phone or the laptop computer. The power supply will become smaller. Since the power adapter can supply multiple powers, multiple specifications of power supply can be input into the mobile phone or laptop computer. At this time, the mobile phone or laptop computer needs to select one of the multiple specifications of power supply, and then the mobile phone or laptop computer sends the selected power supply specification information to the display device. The display device then sends the power supply specification information corresponding to the power supply specification selected by the mobile phone or laptop computer and not yet consumed by the display device to the power adapter. At this time, the power adapter will adjust its supply voltage value and supply current value according to the power supply specification information sent by the display device that has not been consumed by the display device, and send it to the display device.

[0125] Step 409 : The display device determines whether the second power supply value is equal to the first power supply value; if not, execute step 410 .

[0126] It can be understood that after the display device is connected to the second power supply device, the first power supply device will charge the second power supply device in addition to powering the display device. Since the first power supply device can supply multiple powers, the second power supply power provided by the first power supply device for simultaneously powering the display device and charging the second power supply device is not necessarily equal to the first power supply power value provided by the first power supply device. Therefore, the display device needs to first determine whether the second power supply power value is equal to the first power supply power value. If they are equal, no operation is performed. If they are not equal, it is necessary to reset the current brightness, current volume, maximum adjustable brightness and maximum adjustable volume to match the current brightness, current volume, maximum adjustable brightness and maximum adjustable volume with the second power supply power value, so that the display device will not face the problem of insufficient power and cannot work normally, and can also make full use of power to obtain greater brightness and louder volume.

[0127] Step 410: The display device sets the current brightness, current volume, second maximum adjustable brightness, and second maximum adjustable volume that match the second power supply value according to the second power supply value.

[0128] It should be noted that this step is the same as the action performed in step 103 in the above-mentioned embodiment 1. In this step, the current brightness, current volume, second maximum adjustable brightness and second maximum adjustable volume that match the second power supply value are set according to the second power supply value. The above-mentioned step 103 is to set the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume that match the first power supply value according to the first power supply value, which will not be repeated here.

[0129] Step 411: The display device turns off or turns on at least one of a speaker, a wifi module, and a Bluetooth module of the display device according to the second power supply value.

[0130] It should be noted that this step is the same as the action performed in the above step 406, and will not be described in detail here.

[0131] In this embodiment, after the display device is connected to the first power supply device, the first power supply value provided by the first power supply device is first obtained, and then the power-on brightness, power-on volume, first maximum adjustable brightness and first maximum adjustable volume are set according to the first power supply value, so that the power-on brightness, power-on volume, maximum adjustable brightness and maximum adjustable volume of the display device can all match the first power supply value, and then the power consumption of the display device can be intelligently adapted to the first power supply value provided by the first power supply device, which can not only allow the display device to work normally without damaging the first power supply device, but also make full use of the power supply provided by the first power supply device. In addition, at least one of the speaker, wifi module and Bluetooth module of the display device can be turned off or on according to the first power supply value to achieve a balance between the power consumption and function of the display device. In addition, after the display device is connected to the second power supply device, the display device re-acquires the second power supply value provided by the first power supply device, and determines whether the second power supply value has changed compared with the first power supply value. If changed, the display device will reset the current brightness, current volume, current maximum adjustable brightness and current maximum adjustable volume according to the second power supply value, so that the power consumption of the display device can intelligently adapt to the second power supply value provided by the first power supply device in real time.
