Description

Technical Field

[0001] The embodiments of the present application relate to the field of remote control technology, and more specifically, to an external control device of a display device, a backlight display method, and a storage medium. Background Art

[0002] As the functions of display devices are gradually enriched, some smart remote controls have a key backlight function. When the user presses a key, the backlight turns on to illuminate the key, solving the problem that the user cannot see the keys on the remote control clearly in dim light. However, this type of key backlight function turns on as long as the user presses the key, which consumes a lot of power and requires the user to charge the remote control multiple times.

[0003] At present, a photosensitive device and an inductive sensor can be set on the remote control to collect the light intensity of the environment where the remote control is located, and the inductive sensor can be used to detect whether the user has the intention to control the remote control. If it is detected that the user needs to control the remote control, the backlight function of the remote control can be controlled to turn on when the light is dim, so as to avoid the backlight function of the remote control being turned on all the time when the user presses a button, thereby reducing power consumption.

[0004] However, when the light receiving area of ​​the remote control is blocked, the light intensity detected by the remote control will be weakened, which may easily cause the backlight function of the remote control to be mistakenly turned on, resulting in some unnecessary power consumption. Summary of the invention

[0005] The embodiments of the present application provide an external control device, a backlight display method, and a storage medium for a display device, which can be used to solve the problem in the related art that when the light-receiving area of ​​the remote control is blocked, the light intensity detected by the remote control will be weakened, which may easily cause the backlight function of the remote control to be mistakenly turned on, thereby generating some unnecessary power consumption.

[0006] In a first aspect, an embodiment of the present application provides an external control device for a display device, the external control device comprising:

[0007] A plurality of physical buttons, for any one of the physical buttons, is configured to control the display device to start a function corresponding to the physical button if the physical button is triggered;

[0008] A backlight assembly, disposed on the back side of the plurality of physical keys, and configured to illuminate the plurality of physical keys when being lit;

[0009] a gravity sensor configured to detect movement information of the external control device when turned on, and send a first signal according to the movement information, wherein the first signal is used to determine whether the external control device is moved;

[0010] A control component, connected to the gravity sensor, is configured to:

[0011] Determine a first state of the display device, where the first state is power on or power off;

[0012] Determining whether to turn on the gravity sensor according to the first state;

[0013] If the gravity sensor is turned on, whether to turn on the backlight assembly is determined according to the first signal.

[0014] In this embodiment, the external control device includes a plurality of physical buttons, a backlight assembly, a gravity sensor, and a control assembly. The backlight assembly is arranged on the back side of the plurality of physical buttons and is configured to illuminate the plurality of physical buttons when it is turned on. The gravity sensor is configured to detect the motion information of the external control device when it is turned on, and send a first signal according to the motion information. The first signal is used to determine whether the external control device is moved. The control assembly is configured to determine a first state of the display device, the first state being on or off, and to determine whether to turn on the gravity sensor according to the first state. If the gravity sensor is turned on, it is determined whether to turn on the backlight assembly according to the first signal. The present application determines whether to turn on the gravity sensor based on the state of the display device. When the display device is in the on state, it can be realized that based on the illumination information sent by the display device, it is determined whether the illumination intensity condition for turning on the backlight function is met. In the case where the light receiving area of ​​the external control device is blocked, the accuracy of the actual illumination intensity judgment can be improved, and the external control device can be accurately turned on when it is picked up by the user, which can reduce the occurrence of erroneous turning on and further reduce the power consumption of the external control device.

[0015] In some embodiments of the present application, the control component is configured as follows:

[0016] If the first state is power on, sending a light sensing request to the display device, the light sensing request is used to request lighting information of an environment where the display device is located;

[0017] receiving the illumination information sent by the display device;

[0018] Determine whether to turn on the gravity sensor according to the illumination information.

[0019] In this embodiment, when the display device is turned on, a light sensing request is sent to the display device to obtain the light information detected by the display device, so that it can be determined whether to turn on the gravity sensor based on the light information, thereby improving the accuracy of the judgment.

[0023] If so, it is determined whether to turn on the gravity sensor according to the backlight status value, where the backlight status value is used to indicate the light level of the environment where the display device is located.

[0024] In this embodiment, when the display device sends a backlight status value and the external control device is near the display device, it can directly determine whether to turn on the gravity sensor based on the backlight status value, which can further improve the accuracy of the judgment.

[0025] In some embodiments of the present application, the external control device further includes a light sensing component, which is connected to the control component; the light sensing component is configured to collect a first light intensity of an environment where the external control device is located;

[0033] In this embodiment, the control component can determine the first light intensity of the environment where the remote control is located through the voltage signal of the voltage detection circuit.

[0034] In some embodiments of the present application, the control component is configured as follows:

[0035] Determining whether a difference between the first light intensity and the second light intensity is below a preset light intensity;

[0036] If yes, determining that the actual illumination intensity is the average of the first illumination intensity and the second illumination intensity; if no, determining whether the first illumination intensity is greater than the second illumination intensity;

[0037] If yes, then determining the actual illumination intensity to be the average of the first illumination intensity and the second illumination intensity; if no, then determining the actual illumination intensity to be the second illumination intensity;

[0038] Whether to turn on the gravity sensor is determined according to the actual light intensity.

[0039] In this embodiment, when the display device sends the second light intensity, the actual light intensity can be determined more accurately by combining the light intensity collected by the remote control and the light intensity collected by the display device, so that it can be determined whether to turn on the gravity sensor based on the actual light intensity, thereby improving the accuracy of the judgment.

[0081] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0082] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0083] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0084] At present, in order to reduce the problem of high power consumption of the backlight function of the remote control, a photosensitive device and an inductive sensor can be set on the remote control to collect the light intensity of the environment where the remote control is located, and the inductive sensor can be used to detect whether the user has the intention to control the remote control. If it is detected that the user needs to control the remote control, and the light intensity is less than the preset light intensity threshold, it means that the light in the environment where the remote control is located is dim at this time. The remote control can be controlled to turn on the backlight function when the light is dim, so as to avoid the backlight function of the remote control being turned on all the time when the user presses the button, so as to reduce power consumption.

[0085] When using a remote control, the user usually picks up the remote control with one hand to perform corresponding operations. When the user holds the lower end of the remote control, the thumb is usually located at the front area of ​​the lower end of the remote control. The front area is the side where multiple physical buttons of the remote control are located. In order to better detect the light intensity of the environment where the remote control is located, such as Figure 1 As shown, a photosensitive device is usually set in the front area of ​​the lower end of the remote control, so that the area where the photosensitive device is set is the light-receiving area. When the user picks up the remote control, the user's thumb just blocks the light-receiving area of ​​the remote control. For example, the area blocked by the thumb is approximately: length × width = 41cm × 20cm (centimeter), and the light-receiving area of ​​the remote control is approximately: length × width = 43cm × 33mm, and the blocked area accounts for about half of the area of ​​the light-receiving area. If the actual light intensity is 38Lux (lux) at this time, because the light-receiving area is blocked by the hand, the light intensity detected by the remote control is 19Lux. For example, the light intensity threshold for turning on the backlight function is 20Lux. If it is detected that the user needs to operate the remote control at this time, the backlight function will be turned on by mistake.

[0086] Moreover, when users use the remote control for a long time, oil or dirt will be left on the light-receiving area of ​​the remote control, resulting in inaccurate detection of natural light by the remote control. It is also easy to cause the backlight function of the remote control to be mistakenly turned on, resulting in some unnecessary power consumption.

[0087] Therefore, the present application provides an external control device for a display device, which accurately determines whether to turn on the backlight based on the illumination information of the display device. Specifically, it can determine whether to turn on the backlight based on the processing corresponding to the two states of the display device being turned on and turned off. It can be realized that when the display device is in the turned-on state, based on the illumination information sent by the display device, it can be determined whether the illumination intensity condition for turning on the backlight function is met, so that in the case where the light receiving area of ​​the external control device is blocked, etc., the accuracy of the actual illumination intensity judgment can be improved, and the external control device can be accurately turned on when it is picked up by the user, which can reduce the occurrence of erroneous activation and further reduce the power consumption of the external control device.

[0088] For ease of understanding, the following Figure 1 The examples are used to illustrate the application scenarios to which the embodiments of the present application are applicable.

[0089] Figure 1 For a schematic diagram of an application scenario applicable to this application, please refer to Figure 1 , the user can operate the display device 102 through the external control device 101.

[0090] In some embodiments, the external control device 101 may be a remote controller, and the communication between the remote controller and the display device includes infrared protocol communication or Bluetooth protocol communication, and other short-range communication methods, and the display device 102 is controlled wirelessly or wired. The user can control the display device 102 by inputting user commands through buttons on the remote controller, voice input, control panel input, etc.

[0091] In some embodiments, the display device 102 can also be controlled in a manner other than the external control device 101, and can be exemplarily controlled by a smart device 103 (such as a mobile terminal, a tablet computer, a computer, a laptop computer, etc.), for example, using an application running on the smart device to control the display device 102. For another example, the module for acquiring voice commands configured inside the display device 102 receives the user's voice command control, and the voice control device provided outside the display device 102 can also receive the user's voice command control.

[0092] In some embodiments, the display device 102 also communicates data with the server 104. The display device 102 may be allowed to communicate via a local area network (LAN), a wireless local area network (WLAN), and other networks. The server 104 may provide various content and interactions to the display device 102. The server 104 may be one cluster or multiple clusters, and may include one or more types of servers.

[0093] The display device provided in the embodiments of the present application may have various implementation forms, for example, it may be a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc.

[0094] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0095] Figure 2 A schematic diagram of the structure of an external control device for a display device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the external control device 101 includes a plurality of physical buttons 11 , a backlight assembly 12 , a gravity sensor 13 and a control assembly 14 .

[0096] Among them, the control component 14 is respectively connected to multiple physical buttons 11, the backlight component 12 and the gravity sensor 13. Among the multiple physical buttons 11, for any physical button, it is configured to control the display device to execute the function corresponding to the physical button when the physical button is triggered. That is to say, when the user presses the button, the display device can be controlled to implement the function corresponding to the physical button.

[0097] Specifically, the gravity sensor 13 and the control component 14 can be connected via an integrated circuit bus (Inter-Integrated Circuit, I2C), and the backlight component 12 can communicate with the control component 14 via pulse width modulation (Pulse Width Modulation, PWM) control.

[0098] The backlight assembly 12 is disposed on the back side of the plurality of physical keys and is configured to illuminate the plurality of physical keys 11 when being turned on.

[0099] The gravity sensor 13 is configured to detect the motion information of the external control device 101 when it is turned on, and send a first signal according to the motion information, wherein the first signal is used to determine whether the external control device 101 is moved.

[0100] In a possible implementation, the gravity sensor 13 may be an acceleration sensor, also known as a G-sensor, which has high detection accuracy and sensitivity, and can be quickly detected when the external control device 101 moves. The sensor can be set to engineering mode by setting the register, and the operating current is low, for example, 100 μA (microamperes), and the power consumption is low. The control component 104 may be a microcontroller unit (MCU).

[0101] Correspondingly, the operating information may be, for example, the acceleration, velocity and displacement of the external control device 101. When the external control device 101 moves, its physical quantities such as acceleration, velocity and displacement will change, so that the gravity sensor 13 can convert the changes in these physical quantities into corresponding signals and transmit them to the control component 14.

[0102] The control component 14 is configured to: determine the first state of the display device, the first state is power on or off, and determine whether to turn on the gravity sensor 13 according to the first state, if the gravity sensor 13 is turned on, then determine whether to turn on the backlight component 12 according to the first signal.

[0103] First, the conditions for turning on the backlight function of the external control device 101, that is, the conditions for turning on the backlight assembly 12 are described:

[0104] Condition 1: a preset light intensity threshold is met, that is, when the actual light intensity of the remote control is less than the light intensity threshold, it means that the light is dim at this time.

[0105] Condition 2: the external control device 101 is picked up by the user.

[0106] For the above conditions, it can be determined whether condition 1 is satisfied. If so, it is determined whether condition 2 is satisfied. If so, the backlight assembly 12 can be turned on. It can be understood that the gravity sensor 13 is used to sense whether the external control device 101 is moved, that is, whether it is picked up by the user. If condition 1 is satisfied, it can be determined whether to turn on the gravity sensor 13. If it is turned on, condition 2 can be judged.

[0107] Exemplarily, the external control device 101 can determine whether the gravity sensor 13 can be turned on and whether the above condition 1 is met in the following ways:

[0108] Method 1

[0109] When the first state of the display device is turned on, and the external control device 101 can receive the illumination information sent by the display device, the external control device 101 can determine whether to turn on the gravity sensor 13 according to the illumination information of the display device.

[0110] For method 1, there are two cases:

[0111] Case 1: If the illumination information includes a backlight status value, the external control device 101 can determine whether to turn on the gravity sensor 13 according to the backlight status value. Otherwise, the external control device 101 can determine whether to turn on the gravity sensor 13 according to the illumination information of the display device.

[0112] Case 2: If the illumination information includes the second illumination intensity, the external control device 101 may detect the illumination intensity of the environment in which it is located, and determine whether to turn on the gravity sensor 13 according to the detected illumination intensity and the second illumination intensity.

[0113] Method 2

[0114] When the first state of the display device is on, and the external control device 101 cannot receive the illumination information sent by the display device, the external control device 101 can detect the illumination intensity of the environment in which it is located, and determine whether to turn on the gravity sensor 13 according to the detected illumination intensity.

[0115] Method 3

[0116] When the first state of the display device is off, the external control device 101 cannot obtain the illumination information of the display device. The external control device 101 can detect the illumination intensity of the environment in which it is located, and determine whether to turn on the gravity sensor 13 according to the detected illumination intensity.

[0117] Exemplarily, the external control device 101 determines the first state of the display device in the following manner: the external control device 101 sends a connection request to the display device at a preset time interval. If the first state of the display device is on, the display device can communicate with the external control device 101 based on the connection request. When the external control device 101 detects that the communication connection with the display device is successful, it can be determined that the first state of the display device is on. If the external control device 101 does not detect the communication connection with the display device after sending the connection request, it can be determined that the first state of the display device is off.

[0118] Exemplarily, the connection request sent by the external control device 101 may be a Bluetooth connection request, and accordingly, the communication connection between the external control device 101 and the display device may be a Bluetooth connection. Of course, before the external control device 101 sends the Bluetooth connection request to the display device, a Bluetooth connection has been established between the external control device 101 and the display device.

[0119] In this embodiment, whether to turn on the gravity sensor 13 is determined based on the first state of the display device. If it is turned on, whether to turn on the backlight assembly 12 can be determined based on the first signal sent by the gravity sensor 13. It can be realized that whether the illumination intensity condition for turning on the backlight function is met based on the illumination information sent by the display device, so that when the light receiving area of ​​the external control device 101 is blocked, the accuracy of the actual illumination intensity judgment can be improved, and the external control device 101 can be accurately turned on when it is picked up by the user, which can reduce the occurrence of erroneous activation and further reduce the power consumption of the external control device 101.

[0120] In the above embodiment, the external control device 101 detects the light intensity of the environment in which it is located as follows:

[0121] Figure 3 A schematic diagram of the structure of another external control device of a display device provided in an embodiment of the present application, such as Figure 3 As shown, the external control device 101 also includes a light sensing component 15 and a voltage detection circuit 16. The voltage detection circuit 16 is respectively connected to the control component 14 and the light sensing component 15. The light sensing component 15 is configured to collect a first light intensity of the environment where the external control device 101 is located.

[0122] In a possible implementation, the first light intensity collected by the light sensing component 15 can be transmitted to the control component 14 in the form of a voltage signal through the voltage detection circuit 16. Specifically, the voltage detection circuit 16 is configured to detect the voltage signal of the light sensing component 15 and send the voltage signal to the control component 14, and the control component 14 is configured to determine the first light intensity according to the voltage signal.

[0123] Exemplarily, Table 1 shows the voltage values ​​of multiple voltage signals (ie, the output voltage of the voltage detection circuit 16), and the corresponding relationship between the light intensity corresponding to each voltage value:

[0124] Table 1

[0125]

[0126] The control component 14 can determine the first illumination intensity according to the voltage value of the voltage signal through the above correspondence.

[0127] In one possible implementation, the light sensing component 15 may be a solar panel. Specifically, the solar panel may be a solar amorphous silicon panel. The solar amorphous silicon panel may obtain the illumination intensity of ambient light and convert it into a voltage value. The voltage detection circuit 16 detects the voltage of the solar amorphous silicon panel by setting a voltage divider.

[0128] For example, Figure 4 A schematic diagram of the structure of a light sensing component 15 provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the light sensing component 15 includes a solar photovoltaic cell and a voltage regulator diode, wherein the cathode of the voltage regulator diode is connected to the solar photovoltaic cell via a first connecting line, the voltage detection circuit 16 is connected to the first connecting line, and the anode of the voltage regulator diode and the second end of the solar photovoltaic cell are grounded.

[0129] For example, Figure 5 A schematic diagram of the structure of a voltage detection circuit 16 provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the voltage detection circuit 16 includes a first resistor, a second resistor, a third resistor and a transistor. The first end of the first resistor is connected to the first connecting line of the light sensing component 15, the second end of the first resistor is connected to the collector of the transistor, the first end of the second resistor is connected to the control component 14, the second end of the second resistor is connected to the base of the transistor, the first end of the third resistor is connected to the emitter of the transistor through the second connecting line, the second end of the third resistor is grounded, and the control component 14 is connected to the second connecting line through an analog to digital converter (ADC) interface, so that the voltage signal of the output voltage of the voltage detection circuit 16 can be detected, thereby obtaining the voltage value of the voltage signal.

[0130] Specifically, the voltage detection circuit 16 can be connected to the serial communication interface of the control component 14. The control component 14 can turn on the voltage detection circuit 16 through the serial communication interface, so that the voltage signal of the light sensing component 15 is output after voltage division by the voltage detection circuit 16, and the control component 14 detects the output voltage of the voltage detection circuit 16 through the ADC. Exemplarily, the control component 14 can control the voltage detection circuit 16 to be turned on when the level of the serial communication interface is high, and turn off the voltage detection circuit 16 when the level of the serial communication interface is low.

[0131] For example, based on Figure 5 The voltage detection circuit 16 has a principle as shown in the following formula (1):

[0132]

[0133] Among them, V ADC is the emitter voltage of the transistor, that is, the output voltage of the voltage detection circuit 16, V b is the transistor base voltage, V be is the voltage difference between the base voltage and the emitter voltage of the transistor, V pc is the voltage value of the voltage signal of the light sensing component 15, V ec is the voltage difference between the collector voltage of the transistor and the emitter voltage of the transistor, R b is the base current limiting resistor of the three-stage tube, that is, the second resistor, R eIt is the emitter pull-up resistor of the transistor, that is, the third resistor, which plays the role of voltage division. c It is the pull-down resistor of the collector of the transistor, that is, the first resistor, which plays the role of voltage division.

[0134] For example, V pc The value range can be 0-4V, V ec The value is 0.25V, V be The value is 0.6V, V b =3V, R b =2MΩ(megaohm), R e =100kΩ(kilo-ohm), R c =100kΩ, substituting the above value into Formula 1, we can get V ADC =0.5V pc -0.011. As shown in Table 1, assuming that the light intensity threshold is 20 Lux, that is, if the light intensity is less than 20 Lux, one of the conditions for turning on the backlight assembly 12 is met. If the light intensity is less than 20 Lux, Vpc is less than 2.21 V, then V ADC <1.094V, the control component 14 can be based on V ADC The value of determines whether the light intensity meets one of the conditions for turning on the backlight assembly 12. If so, the gravity sensor 13 can be turned on.

[0135] In one possible implementation, based on Figure 4 The external control device 101 can charge various components in the external control device 101 through the light sensing component 15, such as charging the control component 14, the backlight component 12 and the gravity sensor 13, which can further save energy and avoid the user from charging the remote control multiple times.

[0136] Specifically, Figure 6 A structural diagram of another external control device 101 provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the external control device 101 also includes an energy collection component 17, a first power conversion component 18, a second power conversion component 19 and a control switch 20. The energy collection component 17 is connected to the light sensing component 15, the first power conversion component 18 and the second power conversion component 19 respectively, and the energy collection component 17 is configured to collect the voltage of the light sensing component 15 and provide voltage to the first power conversion component 18 and the second power conversion component 19.

[0137] The first power conversion component 18 is connected to the control component 14 and the control switch 20 respectively. The first power conversion component 18 is configured to convert the voltage into a first power supply voltage of the control component 14, and to supply power to the control component 14 and the control switch 20 based on the first power supply voltage.

[0138] The second power conversion component 19 is connected to the backlight component 102 , and the second power conversion component 19 is configured to convert the voltage into a second power supply voltage for the backlight component 12 , and to supply power to the backlight component 12 based on the second power supply voltage.

[0139] The control switch 20 is connected to the gravity sensor 13 . The control switch 20 is configured to supply power to the gravity sensor 13 when it is closed, and to disconnect the power supply of the gravity sensor 13 when it is closed.

[0140] Exemplarily, the energy harvesting component 17 can be an energy harvesting chip, and the charging interface of the energy harvesting chip can be connected to two lithium capacitors. The energy harvesting component 17 can collect the voltage of the light sensing component 15 to charge the lithium capacitor. Exemplarily, the voltage range of the lithium capacitor can be 2.5V-3.8V, and then the voltage is converted by the first power conversion component 18 to a voltage of 3.0V, which can power the control component 14.

[0141] In a possible implementation, the control switch 20 may also be connected to the second power conversion component 19, and the control switch is further configured as follows:

[0142] If the external control device 101 is not moved, the second power conversion assembly 19 is turned off to cut off the power supply to the backlight assembly 12 .

[0143] It can be understood that when the control component 14 determines to turn on the gravity sensor 13 according to the first state of the display device, the power of the gravity sensor 13 is turned on by the control switch 20, and the power of the backlight component 12 is turned on at the same time, but the backlight component 12 is not lit at this time. After determining that the external control device 101 is not picked up by the user, it is not necessary to turn on the backlight component 12 at this time, and the power of the backlight component 12 can be turned off by the control switch 20.

[0144] Specifically, when the control component 14 determines to turn on the gravity sensor 13, the control component 14 can send a first instruction signal to the control switch 20 to instruct the control switch 20 to turn on the power of the gravity sensor 13. When the control component 14 determines not to turn on the gravity sensor 13, the control component 14 can send a second instruction signal to the control switch 20 to instruct the control switch 20 to turn off the second power conversion component 19 to turn off the power of the backlight component 12.

[0145] Specifically, Figure 7 A schematic diagram of the structure of a control switch 20 provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the control switch 20 includes a fourth resistor, a fifth resistor and a metal-oxide-semiconductor field-effect transistor (MOSFET), wherein MOSFET can also be referred to as MOS. Figure 7 The MOS in is the first MOS, the first end of the fourth resistor is connected to the source of the first MOS through the third connecting line, the first power conversion component 18 is connected to the third connecting line, the second end of the fourth resistor is connected to the first end of the fifth resistor through the fourth connecting line, the control component 14 is connected to the fourth connecting line, the second end of the fifth resistor is connected to the gate of the first MOS, and the drain of the first MOS is connected to the second power conversion component 19.

[0146] Exemplarily, the first interface of the control component 14 is connected to the fourth connection line. When the control component 14 determines to turn on the gravity sensor 13, the control component 14 can control the level of the first interface to be high, so that the first MOS of the control switch 20 is turned on, and the interface connected to the source of the first MOS and the second power conversion component 19 is set to a high level, so that the power of the backlight component 12 is turned on, and the power of the gravity sensor 13 is turned on at the same time. If the control component 14 determines that the external control device 101 is not picked up by the user according to the first signal sent by the gravity sensor 13, the power of the backlight component 12 can be turned off by setting the interface connected to the source of the first MOS and the second power conversion component 19 to a low level.

[0147] For example, Figure 8 A schematic diagram of the structure of a backlight assembly 12 provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, the backlight assembly 12 includes a sixth resistor, a second MOS and a plurality of light-emitting diodes (LEDs), wherein a first end of the sixth resistor is connected to a second interface of the control assembly 14, a second end of the sixth resistor is connected to a gate of the second MOS, a source of the second MOS is connected to a second power conversion assembly 19, and a drain of the second MOS is connected to a plurality of LEDs. Specifically, the connection method of the source of the second MOS and the plurality of LEDs can be referred to Figure 8 , Figure 8 The number of LEDs in the figure is only an example and is not limited in this application.

[0148] When the control component 14 determines to turn on the backlight component 12 to illuminate the multiple physical keys 11, the control component 14 can set the second interface to a high level, control the second MOS to turn on, so that the multiple LEDs light up, and the backlight turns on.

[0149] For example, Fig. 9 A schematic diagram of the structure of a first power conversion component 18 provided in an embodiment of the present application is shown in FIG. Fig. 9 As shown, the first power conversion component 18 includes a first voltage regulator, a plurality of capacitors and a resistor. The specific connection relationship can be referred to Fig. 9The first voltage regulator is used to stabilize the input voltage of the first power conversion component 18. For example, when the input voltage of the first power conversion component 18 is 2.7V-3.8V, the first voltage regulator is used to stabilize the output voltage of the first power conversion component 18 to 3V.

[0150] For example, Fig.10 A schematic diagram of the structure of a second power conversion component 19 provided in an embodiment of the present application is shown in FIG. Fig.10 As shown, the second power conversion component 19 includes a second voltage regulator and two capacitors. The specific connection relationship can be referred to Fig.10 The second voltage regulator is used to stabilize the input voltage of the second power conversion component 19 . For example, when the input voltage of the second power conversion component 19 is 2.7V-3.8V, the second voltage regulator is used to convert the output voltage of the second power conversion component 19 to the power supply voltage required by the backlight component 12 .

[0152] Based on the above control device, Fig.12 A flow chart of a backlight display method is provided for an embodiment of the present application, such as Fig.12 As shown, applied to an external control device, the method includes the following steps:

[0153] S1201. Determine a first state of a display device, where the first state is power on or power off.

[0154] The control component can determine the first state of the display device to determine whether the display device is in a power-on state, so that it can be determined whether to turn on the gravity sensor through different processing methods based on different states.

[0155] S1202: Determine whether to turn on the gravity sensor according to the first state.

[0156] S1203: If the gravity sensor is turned on, determine whether to turn on the backlight assembly according to the first signal.

[0157] For the specific implementation of the above steps, please refer to the above embodiments, which will not be described here.

[0158] In this embodiment, the external control device can determine the first state of the display device, and then determine whether to turn on the gravity sensor according to the first state. If the gravity sensor is turned on, it can determine whether to turn on the backlight assembly according to the first signal, wherein the first signal is used to determine whether the external control device is moved. The present application determines whether to turn on the gravity sensor based on the state of the display device, and can determine whether the illumination intensity condition for turning on the backlight function is met based on the illumination information sent by the display device, so that in the case where the light receiving area of ​​the external control device is blocked, etc., the accuracy of the actual illumination intensity judgment can be improved, and the external control device can be accurately turned on when it is picked up by the user, which can reduce the occurrence of erroneous activation and further reduce the power consumption of the external control device.

[0159] Fig.13 A flow chart of a backlight display method is provided for an embodiment of the present application, such as Fig.13 As shown, the control component applied to the external control device, the method comprises the following steps:

[0160] S1301. Determine a first state of a display device, where the first state is power on or power off.

[0161] S1302: If the first state is power on, send a light sensing request to the display device, where the light sensing request is used to request lighting information of an environment where the display device is located.

[0162] If the first state is power on, the control component may send a light sensing request to the display device to request the ambient light of the display device.

[0163] Exemplarily, the display device may detect the light intensity of its environment based on a light sensing module, and the light sensing module may be, for example, an ambient light sensor.

[0164] In a possible implementation, after receiving a light sensing request, the display device may detect the light intensity of its environment through a light sensing module, and then send the light information to the control component.

[0165] In another possible implementation, after the display device is turned on, it detects the light intensity of its environment through the light sensing module at preset time intervals, and sends the light information to the control component after receiving the light sensing request.

[0166] S1303: Receive lighting information sent by a display device.

[0167] In the case where communication is not interrupted, the control component can receive the illumination information sent by the display device. Exemplarily, the illumination information may include a backlight state value and / or a second illumination intensity, wherein the backlight state value may be, for example, 0 or 1, 0 indicating that the illumination intensity of the current environment is low, and meets one of the conditions for turning on the backlight component (i.e., the illumination intensity is less than the illumination intensity threshold), and 1 indicating that the illumination intensity of the current environment is high, and the backlight component may not be turned on.

[0168] Among them, the backlight status value can be determined by the display device based on the light intensity detected by it and the light intensity threshold. For example, if the light intensity threshold is 20Lux and the light intensity detected by the display device is 15Lux, then the backlight status value can be determined to be 0. The light intensity threshold can be sent by the control component to the display device. The backlight status value can also be expressed in other ways, and this application does not impose any restrictions on this.

[0169] Exemplarily, after the display device receives a light sensing request and before turning on the backlight component, when the display device detects the light intensity of the current environment, it can detect the light intensity once every preset time period (for example, 10s), and then the backlight status value can be determined based on the light intensity value and the light intensity threshold. If the backlight status value changes compared to the previous backlight status value, the backlight status value detected this time can be sent to the external control device.

[0170] S1304: Determine whether to turn on the gravity sensor based on the light information.

[0171] After obtaining the light information, the control component can determine whether to turn on the gravity sensor based on the light information.

[0172] In this embodiment, the control component can determine the first state of the display device. When the first state is on, the control component can send a light sensing request to the display device. After receiving the lighting information sent by the display device, it can determine whether to turn on the gravity sensor based on the lighting information, thereby improving the accuracy of the judgment.

[0173] Specifically, S1304 in the above embodiment is described in detail below.

[0174] In a possible implementation, if the illumination information includes a backlight status value, the control component may determine whether to turn on the gravity sensor according to the backlight status value. For example, if the backlight status value is 0, it may be determined to turn on the gravity sensor.

[0175] In another possible implementation, Fig.14 A flow chart of another backlight display method is provided for the embodiment of the present application, such as Fig.14 As shown, the control component applied to the external control device, the method comprises the following steps:

[0176] S1401: If the illumination information includes a backlight status value, obtain distance information, where the distance information is used to indicate whether the external control device is within a preset range of the display device.

[0177] In one possible implementation, the control component may send a detection request to the display device to obtain the distance between the external control device and the display device. For example, the display device may detect the distance between the external control device and the display device after receiving the detection request. Alternatively, the display device may detect the distance between the external control device and the display device when establishing a communication connection with the external control device when the display device is turned on, and then send the distance information to the external control device when receiving the detection request.

[0178] For example, if the display device is connected to the external control device via Bluetooth, the display device may scan the Bluetooth module of the external control device via its Bluetooth module to obtain a received signal strength indication (RSSI) value, and then determine the above distance based on the RSSI value.

[0179] S1402: Determine whether the external control device is within a preset range of the display device based on the distance information.

[0180] If yes, execute S1403, if no, execute S1404.

[0181] S1403: Determine whether to turn on the gravity sensor according to the backlight status value.

[0182] S1404: Obtain a first light intensity and a second light intensity.

[0183] The second light intensity may be the light intensity corresponding to the backlight state value, and the first light intensity is the light intensity detected by the light sensing component of the external control device.

[0184] S1405: Determine whether to turn on the gravity sensor according to the second light intensity and the first light intensity.

[0185] In this embodiment, if the illumination information includes a backlight status value, the control component can determine whether the location of the external control device is within the preset range of the display device. If so, the control component can determine whether to turn on the gravity sensor based on the backlight status value, that is, when the display device and the external control device are close, the gravity sensor can be determined based on the light intensity detected by the display device. If the location of the external control device is not within the preset range of the display device, that is, the display device and the external control device are far away, the control component can obtain a second light intensity, so that it can be determined whether to turn on the gravity sensor based on the first light intensity and the second light intensity, so as to further improve the accuracy of the judgment.

[0186] In another possible implementation, Fig.15 A flow chart of another backlight display method is provided for the embodiment of the present application, such as Fig.15 As shown, the control component applied to the external control device, the method comprises the following steps:

[0187] S1501. If the illumination information includes a second illumination intensity, obtain a first illumination intensity.

[0188] Taking Table 1 as an example, after the ADC interface of the control component detects the voltage value of the voltage signal, the light intensity corresponding to the voltage value is determined in the corresponding relationship in Table 1, which is the first light intensity.

[0189] S1502: Determine whether to turn on the gravity sensor according to the second light intensity and the first light intensity.

[0190] Exemplarily, the control component may determine whether to turn on the gravity sensor according to the following method:

[0191] It is determined whether the difference between the first light intensity and the second light intensity is below the preset light intensity. If so, it means that the external control device and the display device are close at this time, and the actual light intensity is determined to be the average value of the first light intensity and the second light intensity.

[0192] If the difference between the first light intensity and the second light intensity is greater than the preset light intensity, it is determined whether the first light intensity is greater than the second light intensity. If so, it means that the external control device is far away from the display device at this time, and the actual light intensity is determined to be the average of the first light intensity and the second light intensity; if the first light intensity is not greater than the second light intensity, it means that the light receiving area of ​​the remote control is blocked or dirty at this time, and the actual light intensity is determined to be the second light intensity.

[0193] After determining the actual light intensity, you can determine whether to turn on the gravity sensor based on the actual light intensity.

[0194] In this embodiment, when the display device sends the second light intensity, whether to turn on the gravity sensor can be determined in combination with the light intensity collected by the external control device and the light intensity collected by the display device, thereby improving the accuracy of the judgment.

[0195] Fig.16 A flow chart of another backlight display method is provided for the embodiment of the present application, such as Fig.16 As shown, the control component applied to the external control device, the method comprises the following steps:

[0196] S1601. Determine a first state of a display device, where the first state is power on or power off.

[0197] S1602: If the first state is power-on and the control component does not receive the illumination information sent by the display device, obtain a first illumination intensity.

[0198] If the first state of the display device is turned on, and if the communication is not interrupted, if the control component does not receive the lighting information sent by the display device within a first time period (for example, 4 seconds), the control component can obtain the first lighting intensity.

[0199] It can be understood that when the external control device detects the light intensity of its environment through the light sensing component, if the light information sent by the display device is received, the control component can determine whether to turn on the gravity sensor based on the light information. When the display device is in the on state, if the external control device does not receive the light information sent by the display device for a long time (for example, 12 hours), the display device can turn on the light sensing component to detect the light intensity of its environment, so as to determine whether the backlight function of the external control device is turned on based on the light intensity.

[0200] S1603: Determine whether to turn on the gravity sensor according to the first light intensity.

[0201] The control component determines whether to turn on the gravity sensor according to the first light intensity in the following manner: the control component determines whether to turn on the gravity sensor according to the voltage value detected by the ADC interface. For example, taking Table 1 and formula (1) as an example, if the light intensity threshold is 20 Lux, then when the voltage value detected by the ADC interface of the control component is less than 1.094 V, it can be determined that the gravity sensor is turned on; if the voltage value is greater than or equal to 1.094 V, it is determined that the gravity sensor is not turned on.

[0202] In this embodiment, the control component can determine the first state of the display device. If the first state is power on and the control component does not receive the lighting information sent by the display device, it obtains the first light intensity and determines whether to turn on the gravity sensor based on the first light intensity.

[0203] Fig.17 A flow chart of another backlight display method is provided for the embodiment of the present application, such as Fig.17 As shown, the control component applied to the external control device, the method comprises the following steps:

[0204] S1701. Determine a first state of a display device, where the first state is power on or power off.

[0205] S1702: If the first state is shutdown, obtain a first light intensity.

[0206] S1703: Determine whether to turn on the gravity sensor according to the first light intensity.

[0207] In this embodiment, the control component can determine the first state of the display device, and if the first state is off, obtain the first light intensity, and then determine whether to turn on the gravity sensor according to the first light intensity.

[0208] The present application also provides a computer-readable storage medium, which may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, and other media that can store program codes.
