[0003] However, in the prior art, realizing the remote control function of the display device requires multiple operations (e.g., pressing the button on the remote control multiple times) to control the position movement of the indicator point displayed on the display device, which is cumbersome and inconvenient for users. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a remote control system and method for a display device to solve or partially solve the above-mentioned technical problems.

[0008] Based on the same inventive concept, a second aspect of this application proposes a remote control method for a display device, applied to a remote control system for the display device described in the first aspect, wherein the remote control system includes a remote control device and a remote control circuit disposed in the display device, and the method includes:

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0041] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0042] It is understood that before using the technical solutions of the various embodiments in this application, users will be informed of the type, scope of use, and usage scenarios of the personal information involved in an appropriate manner, and user authorization will be obtained.

[0043] For example, upon receiving a user's active request, a prompt message is sent to the user to explicitly inform them that the requested operation will require the acquisition and use of the user's personal information. This allows the user to independently choose, based on the prompt message, whether to provide personal information to the software or hardware such as electronic devices, applications, servers, or storage media performing the operations described in this application.

[0044] As an optional but not limited implementation, in response to a user's active request, sending a prompt message to the user can be done via a pop-up window, where the prompt message can be presented in text format. Furthermore, the pop-up window can also include a selection control allowing the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0045] It is understood that the above notification and user authorization process is merely illustrative and does not limit the implementation of this application. Other methods that comply with relevant laws and regulations may also be applied to the implementation of this application.

[0046] With the development of remote control technology, users can perform various operations (such as adjusting volume, changing channels, etc.) without touching the display device, which greatly improves the convenience of use.

[0047] However, in related technologies, implementing the remote control function of a display device requires multiple operations (e.g., pressing buttons on a remote control multiple times) to control the movement of the position of the indicator point displayed on the display device.

[0048] This application identifies three types of traditional remote controls: infrared remote controls, Bluetooth remote controls, and relative pointing remote controls. All three types have inconveniences in use. For example, infrared and Bluetooth remote controls require manual input (up, down, left, right) to move the TV cursor, which is particularly time-consuming when using the remote control to input on a soft keyboard. Relative pointing remote controls add a gesture sensor to the Bluetooth remote control, enabling air mouse functionality. However, the remote control shifts position whenever it moves off-screen. Without calibration, control is only achieved through relative displacement, resulting in a significant discrepancy between the remote control's pointing direction and the cursor position. All these issues cause inconvenience for users.

[0049] Figure 1 A remote control system for a display device according to an embodiment of this application is shown. The remote control system includes a remote control device and a remote control circuit disposed in the display device.

[0050] The remote control device 110 is configured to: acquire the attitude information and first position information of the remote control device 110;

[0051] The remote control circuit 120 is configured to: receive the attitude information and the position information sent by the remote control device 110, obtain the second position information of the display device, determine the relative position information between the display device and the remote control device 110 based on the first position information and the second position information, and determine the position of the indicator point displayed on the display device according to the attitude information and the relative position information, so as to remotely control the display device based on the position of the indicator point.

[0052] In practice, the remote control system of the display device mainly consists of two parts: the remote control device 110 and the remote control circuit 120 installed inside the display device.

[0053] The remote control device 110 (e.g., a remote controller) is able to acquire its own attitude information and first position information.

[0054] The attitude information refers to the orientation or angle of the remote control device 110 in space, such as whether it is tilted or facing which direction. This information can be obtained through built-in sensors (such as gyroscopes, accelerometers, etc.). The first position information refers to the position of the remote control device 110 in physical space, which can be obtained through Bluetooth positioning, a built-in positioning communication chip (Ultra-Wideband, UWB), or other indoor positioning technologies (such as infrared, ultrasonic, RFID, etc.).

[0055] The remote control circuit 120 is a part inside the display device. It is responsible for receiving signals from the remote control device 110 and performing a series of operations based on these signals.

[0056] The remote control circuit 120 first receives attitude and position information sent by the remote control device 110. In addition to receiving information from the remote control device 110, the remote control circuit 120 also obtains the position information of the display device itself, i.e., the second position information, through some means (possibly the same or different positioning technology as the remote control device 110).

[0057] With the position information of the remote control device 110 and the display device, the remote control circuit 120 can determine their relative position information. This includes distance, direction, etc.

[0058] Based on the attitude and relative position information of the remote control device 110, the remote control circuit 120 can further determine the position of an indicator point on the display device. This indicator point can be a cursor, a highlighted area, or other form of visual indicator used to indicate a specific location or function on the display device that the user wants to control via the remote control device 110.

[0059] The process by which the remote control circuit 120 further determines the position of an indicator point on the display device based on attitude information and relative position information is as follows:

[0060] A pre-established database mapping attitude and relative position information to the position of the indicator point on the display device is used. The position of the indicator point on the display device is obtained by searching this database based on the attitude and relative position information.

[0061] The remote control system of this application provides an intuitive and flexible remote control method by combining the attitude information and first position information of the remote control device 110 with the second position information of the display device. It allows for immediate display of the indicator point on the display device corresponding to the pointing direction of the remote control device 110, regardless of when or where the remote control is picked up in front of the display device, as long as the remote control device 110 is pointed at the display device. This method not only enhances the user experience but also improves the accuracy and efficiency of remote control.

[0062] Through the above scheme, the remote control device can capture its attitude information and first position information in real time, and accurately match them with the second position information of the display device itself obtained by the remote control circuit to determine the relative position information between the two. Then, based on the attitude information and relative position information, the position of the indicator point displayed on the display device is determined. Thus, when the user points the remote control device at the display device, the display device can immediately display the indicator point that precisely corresponds to the direction pointed by the remote control device, realizing the convenient experience of pointing and controlling, and ensuring the user experience without cumbersome button operations.

[0063] In some other embodiments, such as Figure 2 As shown, the remote control device 110 includes: a spatial information acquisition unit 111, an information transmission unit 112, and a power supply management unit 113;

[0064] The spatial information acquisition unit 111 is configured to acquire the attitude information and first position information of the remote control device 110;

[0065] The information sending unit 112 is configured to: receive attitude information and first position information sent by the spatial information acquisition unit 111, and send the attitude information and first position information to the remote control circuit 120;

[0066] The power supply management unit 113 is configured to supply power to the information sending unit 112.

[0067] In practice, the spatial information acquisition unit 111 acquires two key pieces of information from the remote control device 110, namely attitude information and first position information.

[0068] The information transmission unit 112 is responsible for receiving attitude information and first position information from the spatial information acquisition unit 111 and sending this information to the remote control circuit 120. Ensuring the accurate transmission of attitude information and first position information is a key link in the communication between the remote control device 110 and the remote control circuit 120.

[0069] The power management unit 113 is responsible for providing power to the information transmission unit 112, ensuring the continuous operation of the remote control device 110. It may include a battery management system, power conversion circuitry, etc., to ensure that the remote control device 110 receives a stable and secure power supply under various conditions.

[0070] In some embodiments, such as Figure 3 As shown, the spatial information acquisition unit 111 includes: an attitude information acquisition subunit 1111 and a position information acquisition subunit 1112;

[0071] The attitude information acquisition subunit 1111 is configured to acquire the attitude information of the remote control device 110.

[0072] The location information acquisition subunit 1112 is configured to acquire the first location information of the remote control device 110.

[0073] In specific implementation, the attitude information acquisition subunit 1111 acquires the attitude information of the remote control device 110. Attitude information refers to the direction or angle of the remote control device 110 in space, such as whether it is tilted, by how many degrees, or whether it has rotated, which helps to understand how the user conveys instructions or intentions by operating the attitude of the remote control device 110.

[0074] The location information acquisition subunit 1112 is responsible for acquiring the first location information of the remote control device 110. The first location information refers to the physical location of the remote control device 110 in space, such as which corner of the room it is in, or its distance and direction relative to a reference point. This accurate location information is crucial for realizing location-based interactive functions.

[0075] By dividing the device into an attitude information acquisition subunit 1111 and a position information acquisition subunit 1112, the device achieves comprehensive and accurate capture of the spatial information (i.e., attitude information and first position information) of the remote control device 110, thereby providing a more natural and smooth interactive experience.

[0076] In some embodiments, such as Figure 4 As shown, the location information acquisition subunit 1112 includes: a first transmitting antenna 11121, a first receiving antenna 11122, a second receiving antenna 11123, and a first positioning communication chip 11124;

[0077] The first transmitting antenna 11121 is configured to transmit a pulse signal to the remote control circuit 120;

[0078] The first receiving antenna 11122 is configured to receive a feedback signal based on a pulse signal from the remote control circuit 120 and record the first time the feedback signal is received.

[0079] The second receiving antenna 11123 is configured to receive a feedback signal from the remote control circuit 120 based on a pulse signal and record a second time of receiving the feedback signal.

[0080] The first positioning communication chip 11124 is configured to: acquire the first antenna position information of the first receiving antenna 11122 and the second antenna position information of the second receiving antenna 11123, receive the first time transmitted by the first receiving antenna 11122 and the second time transmitted by the second receiving antenna 11123, determine the first time difference between the first time and the second time, and determine the first position information of the remote control device 110 based on the first antenna position information, the second antenna position information and the first time difference.

[0081] In practice, the primary task of the first transmitting antenna 11121 is to send a pulse signal to the remote control circuit 120. This pulse signal acts as a start signal, triggering the remote control circuit 120 to generate and send a feedback signal.

[0082] When the remote control circuit receives a pulse signal, it will send a feedback signal based on that signal. The first receiving antenna 11122 is responsible for receiving this feedback signal and recording the specific time of signal reception (i.e., the first time).

[0083] The second receiving antenna 11123 is similar to the first receiving antenna 11122. The second receiving antenna 11123 is also used to receive the feedback signal based on the pulse signal from the remote control circuit 120, but it records a different point in time (i.e., a second time). Due to the different physical locations of the two receiving antennas, the time at which they receive the feedback signal will differ.

[0084] The first positioning communication chip 11124 acquires the position information of the two receiving antennas (i.e., the position information of the first antenna and the position information of the second antenna). Then, it also receives the time information recorded by the two receiving antennas (the first time and the second time) and calculates the difference between the two times (i.e., the first time difference). Finally, using this information (including the positions of the two antennas, the two receiving times, and the time difference), the first positioning communication chip 11124 can accurately calculate the first position information of the remote control device 110.

[0085] This method does not require the installation of additional positioning devices (such as GPS receivers) on the remote control device 110, making it more flexible and applicable to various types of remote control devices 110.

[0086] Furthermore, due to the use of pulse signals and feedback signals, this method has a strong resistance to external interference and can work stably in complex environments.

[0087] The location information acquisition method based on pulse signals and time differences has the advantages of high precision, flexibility and strong anti-interference, and can be applied to scenarios that require precise positioning of remote control device 110.

[0088] In some embodiments, such as Figure 5 As shown, the first pin of the first positioning communication chip is used to receive a power supply signal. The second, third, fourth, and fifth pins of the first positioning communication chip are respectively connected to the information transmission unit. The sixth pin of the first positioning communication chip is grounded. The seventh pin of the first positioning communication chip is connected to the first transmitting antenna. The eighth pin of the first positioning communication chip is connected to the first receiving antenna. The ninth pin of the positioning communication chip is connected to the second receiving antenna.

[0089] In practice, the first positioning communication chip receives power input through its first pin to ensure its normal operation.

[0090] Pins 2, 3, 4, and 5 are used to transmit data, control signals, or synchronization signals to communicate with the information transmission unit. The information transmission unit is responsible for sending positioning data or other relevant information to the chip for processing or forwarding.

[0091] Pin 6 is grounded to provide a stable reference potential (typically zero). Grounding helps reduce the effects of electromagnetic interference (EMI) and electrostatic discharge (ESD) on the chip, ensuring stable device operation.

[0092] The first positioning communication chip controls or drives a transmitting antenna (first transmitting antenna) via its seventh pin to send signals into external space. In positioning communication, this typically involves transmitting radio frequency (RF) signals for communication or positioning.

[0093] The eighth pin of the first positioning communication chip is connected to a receiving antenna (first receiving antenna) for receiving signals from external space. These signals may include radio frequency signals from other positioning base stations or devices, used to determine the device's location.

[0094] Similar to pin 8, pin 9 is also connected to a receiving antenna (second receiving antenna), which can provide an additional receiving channel to improve receiving performance, enhance signal coverage, or enable multipath positioning.

[0095] This approach improves the performance, stability, and flexibility of the first positioning communication chip by optimizing the connection between the chip and its peripheral components, enabling it to perform positioning tasks more accurately and adapt to various complex environments.

[0096] For example Figure 5 As shown, pin 1 of the UltraWide Band (UWB) positioning chip U2 (the first positioning communication chip) is powered by a 3.3V supply voltage (3V3_UWB), with a series ferrite bead L1 and a ground bypass capacitor C4 for power filtering. Pins 2-5 (the second, third, fourth, and fifth pins) are the Serial Peripheral Interface (SPI), and pin 6 (the sixth pin) is grounded. Pin 7 (the seventh pin) is connected to the transmitting antenna through a ground impedance matching inductor L4, a series capacitor C9, and a ground impedance matching capacitor C11. Pin 8 (the eighth pin) is connected to the first receiving antenna through a ground impedance matching inductor L3, a series capacitor C5, and a ground impedance matching capacitor C18. Pin 9 (the ninth pin) is connected to the second receiving antenna through a ground impedance matching inductor L2, a series capacitor C2, and a ground impedance matching capacitor C3.

[0097] In some embodiments, such as Figure 6 As shown, the attitude information acquisition subunit includes: an inertial measurement chip;

[0098] The first pin of the inertial measurement chip is connected to the information transmission unit, the second pin of the inertial measurement chip is used to detect the level status, the third and fourth pins of the inertial measurement chip are respectively connected to the information transmission unit, the fifth pin of the inertial measurement chip is grounded, and the sixth pin of the inertial measurement chip is used to receive the power supply signal.

[0099] In practice, inertial measurement chips are used to measure the inertial properties of an object, such as acceleration and angular velocity (gyroscope). These measurements are crucial for determining the object's motion state or attitude information.

[0100] The inertial measurement chip transmits data to the information transmission unit through its first pin. This data may include attitude information such as acceleration and angular velocity.

[0101] The second pin is used to detect certain external voltage levels, such as interrupt signals, reset signals, or other control signals. This helps the inertial measurement chip synchronize or control external circuits.

[0102] In addition to the first pin, two other pins are connected to the information transmission unit. These can be used to transmit additional data, control signals, or implement a certain communication protocol. For example, the third pin can be used to transmit some status information, while the fourth pin can be used to receive instructions or configuration information from the information transmission unit.

[0103] Pin 5, grounded, is used to provide a stable reference potential for the circuit. Grounding helps ensure the stability and reliability of the circuit.

[0104] The sixth pin is used to receive the power supply signal from the external power source to ensure that the inertial measurement chip can work properly.

[0105] This approach ensures that the attitude information acquisition subunit can operate stably and efficiently, and transmits accurate attitude information to subsequent processing units.

[0106] For example Figure 6 As shown, the inertial measurement chip is U7. Pin 1 (the first pin) is connected to a 3.3V power supply (3V3_GS) via resistor R31 for address configuration. Pin 2 (the second pin) is pulled up to a 3.3V power supply signal (3V3_GS) via resistor R84; a low level triggers an interrupt. Pins 3 and 4 (the third and fourth pins) are for the data and clock signals of the Inter-Integrated Circuit (I2C) interface, pulled up via resistors R85 and R86. Pin 5 (the fifth pin) is grounded, and pin 6 (the sixth pin) is powered by a 3.3V power supply (3V3_GS) and connected to a bypass capacitor C18 for power filtering.

[0107] In some embodiments, such as Figure 7 As shown, the information sending unit 112 includes: a first Bluetooth master control chip 1121 and a first Bluetooth antenna 1122;

[0108] The first Bluetooth master control chip 1121 is configured to receive attitude information and first position information sent by the spatial information acquisition unit 111;

[0109] The first Bluetooth antenna 1122 is configured to receive attitude information and first position information sent by the first Bluetooth master control chip 1121, and send the attitude information and first position information to the remote control circuit 120.

[0110] In practice, the first Bluetooth master control chip 1121 is responsible for receiving data from the spatial information acquisition unit 111. This data mainly includes the attitude information and first position information of the remote control device 110. The attitude information may include the device's rotation angle, tilt degree, etc., while the first position information refers to the device's specific position in space.

[0111] The first Bluetooth antenna 1122 transmits the information received by the first Bluetooth main control chip 1121 to the remote control circuit 120 via Bluetooth communication technology.

[0112] Because the first Bluetooth antenna 1122 uses Bluetooth technology, it has stable communication performance and strong anti-interference capabilities. Therefore, through the cooperation of the first Bluetooth main control chip 1121 and the first Bluetooth antenna 1122, it can be ensured that the information transmission unit 112 can efficiently and reliably transmit attitude information and first position information to the remote control circuit 120, providing strong support for precise remote control.

[0113] In some embodiments, such as Figure 8 As shown, the first pin of the first Bluetooth master control chip is grounded, the second pin of the first Bluetooth master control chip is used to receive power supply signals, the third pin of the first Bluetooth master control chip is connected to the first Bluetooth antenna, and the other pins of the first Bluetooth master control chip, except for the first pin, the second pin and the third pin, are connected to the power supply management unit.

[0114] In practice,

[0115] The first pin of the first Bluetooth master control chip is connected to the circuit's ground line to provide a stable reference potential and ensure that the circuit works normally.

[0116] The second pin of the first Bluetooth master control chip is used to receive power signals from a power source (which may be a battery or an external power source), thus ensuring that the first Bluetooth master control chip can work properly.

[0117] The third pin of the first Bluetooth master control chip is connected to the first Bluetooth antenna and is used to send and receive wireless signals.

[0118] All pins except the first, second, and third pins are connected to the power management unit to ensure that the first Bluetooth master control chip can work stably under various conditions.

[0119] This approach ensures the stable operation of the first Bluetooth master control chip, enables Bluetooth communication, and provides precise control over the functions of the first Bluetooth master control chip and the reliability of the entire module.

[0120] In addition, other pins can also be connected to peripheral units set up by the remote control device.

[0121] For example Figure 8As shown, pin 1 of the Bluetooth System-on-Chip (SoC) U5 (the first Bluetooth main control chip) is grounded, pin 2 is powered by a 3.3V power supply (VCC3V3), and connected to two bypass capacitors C14 and C15 for power filtering. Pin 3 is connected to the antenna connector J1 through inductor L6, capacitor C16 to ground, and inductor L5. L6, C16, and L5 achieve antenna impedance matching and RF filtering. Other GPIO ports are used to connect other unit circuits, including power management units and / or peripheral units.

[0122] In some embodiments, such as Figure 9 As shown, the power supply management unit 113 includes: a universal serial bus interface 1131, a charging management chip 1132, a battery fuel gauge 1133, a battery 1134, a first switching power supply 1135, and a second switching power supply 1136.

[0123] The universal serial bus interface 1131 is configured to connect to an external power supply for charging the battery 1134.

[0124] The charging management chip 1132 is configured to control the charging and / or discharging of the battery 1134;

[0125] The battery power meter 1133 is configured to: monitor the power of the battery 1134, and receive the discharge signal of the battery sent by the charging management chip 1132, so as to control the discharge voltage of the battery 1134 based on the discharge signal, and send the discharge voltage to the first switching power supply 1135 and / or the second switching power supply 1136.

[0126] The battery 1134 is configured to provide a discharge voltage to the battery fuel gauge 1133;

[0127] The first switching power supply 1135 is configured to convert the discharge voltage into a preset voltage required by the remote control device 110;

[0128] The second switching power supply 1136 is configured to convert the discharge voltage into a preset voltage required by the remote control device 110.

[0129] In practice, the Universal Serial Bus interface 1131 (Type-C interface) is used to connect an external power supply, such as charging the battery 1134 by connecting it to a power supply device via a Universal Serial Bus (USB) cable. In this way, the external power supply can charge the battery 1134 through this interface.

[0130] The charging management chip 1132 is responsible for controlling the charging and / or discharging process of the battery 1134. It may include functions such as overcharge protection, over-discharge protection, and short-circuit protection to ensure the safe use of the battery 1134.

[0131] The battery fuel gauge 1133 monitors the battery level of the battery 1134 and receives battery discharge signals from the charging management chip 1132. Based on these signals, it can control the battery discharge voltage and send this voltage to the first switching power supply 1135 and / or the second switching power supply 1136. By monitoring the battery level of the battery 1134 in real time and precisely controlling the discharge voltage, the remote control device 110 is ensured to operate normally when the battery 1134 has sufficient power.

[0132] Battery 1134 provides discharge voltage to battery fuel gauge 1133 to provide a continuous power supply to remote control device 110, enabling the device to operate normally.

[0133] The first switching power supply 1135 and the second switching power supply 1136 both convert the discharge voltage provided by the battery 1134 into the preset voltage required by the remote control device 110. This redundancy serves as a backup to improve system reliability. Precise voltage conversion ensures that all components inside the remote control device 110 receive the correct operating voltage, thereby guaranteeing normal operation and performance stability. Simultaneously, the redundant switching power supply design improves system reliability and reduces the risk of device failure due to a single power supply failure.

[0134] The power management unit 113 achieves efficient, safe, and reliable power management for the remote control device 110 by precisely controlling the charging and discharging process of the battery 1134, monitoring the battery level in real time, and converting the battery voltage to the preset voltage required by the device. This not only extends the service life and performance stability of the device but also improves the user experience and satisfaction.

[0135] In some embodiments, such as Figure 10 As shown, the first pin of the charging management chip is used to receive the power supply signal, the second pin of the charging management chip is connected to the remote control device, the third, fourth and fifth pins of the charging management chip are all grounded, the sixth pin of the charging management chip is used to receive the power supply signal, the seventh pin of the charging management chip is connected to the universal serial bus interface, and the eighth and ninth pins of the charging management chip are connected to the battery fuel gauge.

[0136] In practice, the first pin of the charging management chip is used to receive the power supply signal from the power source (such as a power adapter) to provide the necessary power to its internal circuitry.

[0137] The second pin of the charging management chip has a communication connection with the remote control device (such as a remote controller) to receive commands from the remote control device, such as starting charging, stopping charging, or adjusting the charging current. This design makes charging management more flexible and controllable.

[0138] The third, fourth, and fifth pins are grounded to ensure stable operation of the internal circuitry of the charging management chip and to prevent external interference.

[0139] Pin 6 is used to receive a power supply signal, providing additional power input to meet the needs of the charging management chip under high load or specific operating modes. Alternatively, it can be used as a backup power input to increase system reliability.

[0140] Pin 7 connects to a Universal Serial Bus interface for data transmission and / or receiving electrical energy from a power source.

[0141] Pins 8 and 9 are connected to a battery fuel gauge to monitor the battery's state of charge. A battery fuel gauge is a device that measures and reports the remaining battery capacity. By connecting to a charging management chip, precise control of the battery charging process can be achieved, preventing overcharging or over-discharging and thus extending battery life.

[0142] This connection method for the charging management chip improves the flexibility and stability of the charging process.

[0143] For example Figure 10 As shown, the integrated circuit (IC) for charging management is U8. The power bus or power input terminal (VBUS_C) is connected to pin 1 (i.e., the first pin) through fuse F1, transient voltage suppressor (TVS) diode D5, and capacitor C25. Pin 2 (i.e., the second pin) is connected to the Bluetooth system-on-chip (SoC) through pull-up resistor R46, pull-down resistor R50, and series resistor R55 to indicate the charging status.

A capacitor C22 is connected between pins 8 and 9 (i.e., the eighth and ninth pins). Pin 9 (i.e., the ninth pin) is output through a filter inductor L7, a sampling resistor R48, and a capacitor C24 to ground.

[0144] In some embodiments, such as Figure 11 As shown, the battery fuel gauge includes: a fuel gauge chip;

The eighth pin of the fuel gauge chip is connected to the first switching power supply and the second switching power supply, respectively.

[0146] In practice, the fuel gauge chip is responsible for measuring the battery's charge and transmitting the relevant information to other components or devices.

[0147] The first pin of the fuel gauge chip is connected to both the charging management chip and the battery, indicating that the fuel gauge chip can directly obtain power information from the battery, and can also receive signals from the charging management chip to understand the battery's charging status.

[0148] In addition, the second pin of the fuel gauge chip is grounded, which provides a stable reference potential for the fuel gauge chip.

[0150] Pins 5, 6, and 7 are grounded, providing additional stability and grounding protection.

[0151] The eighth pin is connected to the first and second switching power supplies to provide external power to the fuel gauge chip, or to receive different voltage or current inputs through these two switching power supplies to adapt to different operating conditions.

[0152] This battery power meter connection method can improve the accuracy of power measurement and help improve the stability and security of the remote control system of the display device.

[0153] For example Figure 11As shown, U12 is a battery meter chip. Pin A1 (the first pin) is connected to the 3.3V power supply (VCC3V3) via pull-up resistor R59, and its output pin is connected to the Bluetooth system-on-chip (SoC) to indicate low battery. Pin B1 (the second pin) is connected to ground via resistor R65 to detect battery connection. Pins A3 (the third pin) and A2 (the fourth pin) are the clock and data for the Inter-Integrated Circuit (I2C) interface, pulled up to VCC3V3 via resistors R63 and R61. Pins B2 (the fifth pin) and C1 (the sixth pin) are grounded. Pin B3 (the seventh pin) is the internal 1.8V output pin, grounded via capacitor C36. Pin C3 (the eighth pin) is connected to the positive terminal of battery J2 via capacitor C35, and the negative terminal of battery J2 is grounded. Pin C3 (i.e., pin 8) is connected to the system power supply voltage (VSYS) to power the subsequent system.

[0154] In some embodiments, such as Figure 12 As shown, the first switching power supply includes: a first switching power supply chip;

[0155] The first pin of the first switching power supply chip is connected to the fuel gauge chip, the second pin of the first switching power supply chip is connected to the remote control device, the third, fourth, fifth and sixth pins of the first switching power supply chip are used to output power supply signals, the seventh pin of the first switching power supply chip is grounded, and the eighth and ninth pins of the first switching power supply chip are used to receive power supply signals.

[0156] In practice, the first switching power supply chip is responsible for controlling the power supply's switching, voltage conversion, and current output.

[0157] The fuel gauge chip monitors the battery's state of charge. Its first pin can be used to transmit information or control signals related to battery charge. The second pin provides power to the remote control device or receives control signals from the remote control device. The third, fourth, fifth, and sixth pins are used to output power signals, which can be connected to different circuits or components to provide them with the required voltage and current. The seventh pin is grounded to ensure the stability and safety of the circuit. The eighth and ninth pins are used to receive power signals, ensuring the operation of the first switching power supply chip.

[0158] This connection method for the first switching power supply improves the performance and reliability of the power management unit.

[0159] For example Figure 12As shown, the first switching power supply chip is U9. Pin 1 (the first pin) is powered by the system supply voltage (VSYS) and connected to capacitor C23 for power filtering. Pin 2 (the second pin) is also connected to the system supply voltage (VSYS) and is enabled by default upon power-up. Pins 3 (the third pin), 4 (the fourth pin), 5 (the fifth pin), and 6 (the sixth pin) are output voltage configuration pins, all connected to the system supply voltage (VSYS) and configured for 3.3V output. Pin 9 (the ninth pin) is connected to the 3.3V power supply terminal (VCC3V3) through power inductor L8 and capacitor C28. Inductor L8 and capacitor C26 filter the output power. Pin 7 (the seventh pin) is grounded.

[0160] In some embodiments, such as Figure 13 As shown, the second switching power supply includes: a second switching power supply chip;

[0161] The first pin of the second switching power supply chip is connected to the fuel meter chip, the second pin of the second switching power supply chip is connected to the remote control device, the third, fourth, fifth and sixth pins of the second switching power supply chip are used to output power supply signals, the seventh pin of the second switching power supply chip is grounded, and the eighth and ninth pins of the second switching power supply chip are used to receive power supply signals.

[0162] In practice, the second switching power supply chip is responsible for controlling and managing the conversion and distribution of electrical energy.

[0163] The power meter chip is used to monitor the status of the power supply (such as power, voltage, etc.) and feeds this information back to the second switching power supply chip through the first pin of the second switching power supply chip so that appropriate adjustments or protection can be made.

[0164] The remote control device can control the second switching power supply chip via the second pin, such as turning it on, off, or adjusting the power output. Pins three, four, five, and six are used to provide power signals to other devices or components to meet their power needs. Furthermore, pin seven is grounded to ensure circuit stability and safety. Pins eight and nine are used to receive externally input power as the operating power supply for the second switching power supply chip or for other specific power distribution tasks. This improves the flexibility, controllability, and safety of the second switching power supply.

[0165] For example Figure 13As shown, the second switching power supply chip is U11. Pin 1 (the first pin) is powered by the system supply voltage (VSYS) and connected to a capacitor C34 for ground filtering. Pin 2 (the second pin) is connected to the Bluetooth System-on-Chips (SoC), which controls the output. The pull-down resistor R66 is configured to not output by default. Pins 3 (the third pin), 4 (the fourth pin), 5 (the fifth pin), and 6 (the sixth pin) are the output voltage configuration pins, all connected to the system supply voltage (VSYS) and configured for 3.3V output. Pin 9 (the ninth pin) is connected to the 3.3V power supply terminal (VCC3V3) through power inductor L9 and capacitor C30. Inductor L9 and capacitor C30 filter the output power. Pin 7 (the seventh pin) is grounded.

[0166] In some embodiments, such as Figure 9 As shown, the remote control device also includes peripheral units, which include, but are not limited to: buzzer, flash memory, integrated circuit (IC), infrared emitter (IR), microphone (MIC), light-emitting diode (RGB LED), single-pole double-throw switch and membrane keypad.

[0167] The buzzer connects to the Bluetooth SoC and controls its sound via pulse width modulation (PWM). The FLASH memory stores program code or algorithms and connects to the Bluetooth SoC via a Serial Peripheral Interface (SPI) bus. The touch IC acquires touch data, enabling richer functions and page scrolling for the remote control, and connects to the Bluetooth SoC via an Inter-Integrated Circuit (I2C) bus. An IR transmitter emits infrared light, providing infrared remote control functionality when Bluetooth is not in use. The microphone collects sound information for voice control. RGB LEDs indicate the remote control's operating status. A single-pole double-throw switch switches the remote control's operating mode, controlling the pointing function. The membrane buttons, like traditional remote controls, provide button control and connect to the Bluetooth SoC via an analog-to-digital converter (ADC).

[0168] The touch IC circuit connection diagram is as follows: Figure 14 As shown, pins 1 and 2 of the touch IC U3 are I2C interfaces. I2C is an open-drain output, which is connected to the power supply terminal (VCC3V3_TOUCH) that provides 3.3V voltage through pull-up resistors R4 and R5.

[0169] Pin 3 is the interrupt pin, which is connected to the power supply terminal (VCC3V3_TOUCH) that provides 3.3V voltage through a pull-up resistor. After an interrupt event occurs, it goes low.

[0170] Pin 4 is powered by a 3.3V power supply (VCC3V3_TOUCH), and connected to two bypass capacitors C6 and C7 for power filtering. Pin 5 is grounded. Pins 6 to 15 are connected to the 10 touch channels through series resistors R6 to R15.

[0171] In addition, the circuit connection diagram of a single-pole double-throw switch is as follows: Figure 15 As shown, pin 1 is connected to the power supply terminal (VCC3V3) providing 3.3V through current-limiting resistor R41. Pin 2 is connected to the Bluetooth SoC through ground ESD protection diode D4, series resistor R43, and filter capacitor C21. Pin 3 is grounded.

Pin 8 is powered by the power supply terminal (VCC3V3_PER) that provides a 3.3V voltage and is connected to the bypass capacitor C28 to ground for power filtering.

[0173] The buzzer circuit connection diagram is as follows: Figure 17 As shown, pin 2 of buzzer B1 is positive, connected to the power supply terminal (VCC3V3) providing 3.3V, and pin 1 is negative. A freewheeling diode is connected in parallel between pins 1 and 2 to prevent overvoltage. A parallel capacitor can change the resonant frequency and adjust the buzzer volume. R33 limits the current and controls the buzzer loudness. Q4 is an NPN transistor. Its base is connected to the Bluetooth SoC through the current-limiting resistor R39 and grounded through resistor R40 to achieve the default off state. The transmitter is grounded, and the collector is connected to the negative terminal of the buzzer through R33.

[0174] RGB LED circuit connection diagram as follows Figure 18As shown, U6 is a common-anode RGB LED, with pin 2 being the anode, connected to a 3.3V power supply (VCC3V3_PER). Pins 1, 3, and 4 correspond to the cathodes of the R, G, and B LEDs, respectively. R24, R25, Q1, and R23 form a transistor switching circuit, controlled by the Bluetooth SoC. When the level is high, the red LED (R LED) lights up. R29, R30, Q2, and R32 form a transistor switching circuit, controlled by the Bluetooth SoC. When the level is high, the blue LED (B LED) lights up. R37, R38, Q3, and R35 form a transistor switching circuit, controlled by the Bluetooth SoC. When the level is high, the green LED (G LED) lights up.

[0175] The circuit connection diagram of the membrane keypad is as follows: Figure 19 As shown, SW1, SW2, SW3, SW4, and SW5 are five membrane buttons. One end is grounded, and the other end is connected to voltage divider resistors R18, R19, R20, R21, and R22 respectively. These are connected in parallel and then pulled up to 3.3V (VCC 3V3) through R16. Different values ​​of R18 through R22 result in different voltages when a button is pressed. Afterwards, an electrostatic diode D1, a series resistor R17, and a capacitor C10 are connected to ground and then to the Bluetooth SoC. D1 is the electrostatic diode, R17 is the current-limiting resistor, and C10 is the anti-shake filter capacitor.

[0176] The circuit connection diagram of the infrared emitting tube is as follows: Figure 20 As shown, D3 is an IR transmitter. Its positive terminal is connected to VCC3V3 through resistor R42, and its negative terminal is connected to the collector of Negative-Positive-Negative (NPN) transistor Q5. The transmitter of Q5 is grounded, and its base is connected to the collector of NPN transistor Q6. It is also connected to the Bluetooth SoC through R44. The Bluetooth SoC outputs an infrared carrier wave. The transmitter of Q6 is grounded, and its base is connected to the Bluetooth SoC through resistor R45. The Bluetooth SoC controls the conduction and cutoff of Q6 to achieve key value transmission.

[0177] MIC circuit connection diagram as follows Figure 21 As shown, U13 is an analog microphone chip. Pin 4 is connected to the 3.3V power supply terminal (VCC3V3_PER) through capacitors C32 and C33 to ground and series resistor R62. Pins 5, 6, 2, and 3 are grounded. Pin 1 is connected to the positive microphone terminal (MIC_P) of the Bluetooth SoC through filter capacitor C31, and the negative microphone terminal (MIC_N) is grounded through filter capacitor C29 and resistor R60.

[0178] In addition, such as Figure 9As shown, the wireless communication unit (i.e., the information transmission unit) consists of a Bluetooth SoC (i.e., the first Bluetooth main control chip) and a Bluetooth (BT) antenna (i.e., the first Bluetooth antenna). The Bluetooth SoC, as the main control chip, controls all functions of the entire remote control (i.e., the remote control device) to operate according to certain logic. The BT antenna is used for transmitting and receiving electromagnetic waves. The wireless positioning unit (i.e., the location information acquisition subunit) consists of a UWB chip (i.e., the first positioning communication chip), a transmitting antenna (i.e., the first transmitting antenna), a first receiving antenna, and a second receiving antenna. The UWB chip has a built-in positioning algorithm and can acquire coordinate position information (i.e., the first position information). The UWB chip is connected to the Bluetooth SoC via a synchronous serial communication bus (Serial Peripheral Interface, SPI) to send the position information to the Bluetooth SoC. The transmitting antenna and the two receiving antennas are used for transmitting and receiving electromagnetic waves. The inertial measurement unit is connected to the Bluetooth SoC via a serial communication bus (Inter-Integrated Circuit, I2C). When the remote control's attitude changes, the inertial measurement unit can acquire 3-axis acceleration and 3-axis angular velocity (i.e., attitude information) and send the data to the Bluetooth SoC.

[0179] In some embodiments, such as Figure 22 As shown, the remote control circuit 120 includes: a location information acquisition unit 121 and a spatial information receiving unit 122;

[0180] The location information acquisition unit 121 is configured to acquire the second location information of the display device;

[0181] The spatial information receiving unit 122 is configured to: receive attitude information and first position information sent by the remote control device 110, and receive second position information sent by the position information acquisition unit 121; determine the relative position information between the display device and the remote control device 110 based on the first position information and the second position information; and determine the position of the indicator point displayed on the display device according to the attitude information and the relative position information, so as to remotely control the display device based on the position of the indicator point.

[0182] In specific implementation, the position information acquisition unit 121 acquires the second position information of the display device (such as a television, monitor, etc.). The second position information refers to the specific coordinates or position of the display device in space, which may include its height, width, and depth (in three-dimensional space) or simply its horizontal and vertical positions (in two-dimensional space, relative to a reference point).

[0183] The spatial information receiving unit 122 is responsible for receiving attitude information and first position information from the remote control device 110, and determining the position of the indicator point displayed on the display device based on this information. It also receives second position information sent by the position information acquisition unit 121.

[0184] The spatial information receiving unit 122 first determines the relative positional relationship between the display device and the remote control device 110 based on the first positional information and the second positional information. This may include distance, direction, etc.

[0185] Then, combining the attitude information of the remote control device 110 with the aforementioned relative position information, the position of an indicator point that should be displayed on the display device is determined. This indicator point is typically used to indicate the current position of the remote control device 110, thereby allowing the user to "point" to a specific element or area on the display device by moving the remote control device 110.

[0186] This remote control circuit 120 and its processing method determine the position of the indicator point by combining position information and attitude information. This allows users to control the display device simply by moving and pointing at the remote control device, without having to precisely click or touch the screen. This improves the interactivity and intuitiveness between the user and the display device, and realizes a more intuitive, flexible and adaptable remote control method.

[0187] In some embodiments, such as Figure 23 As shown, the location information acquisition unit 121 includes: a second transmitting antenna 1211, a third receiving antenna 1212, a fourth receiving antenna 1213, and a second positioning communication chip 1214;

[0188] The second transmitting antenna 1211 is configured to transmit a pulse signal to the remote control device 110;

[0189] The third receiving antenna 1212 is configured to receive a feedback signal from the remote control device 110 based on a pulse signal and record a third time of receiving the feedback signal.

[0190] The fourth receiving antenna 1213 is configured to receive a feedback signal from the remote control device 110 based on a pulse signal, and record the fourth time of receiving the feedback signal.

[0191] The second positioning communication chip 1214 is configured to: acquire the third antenna position information of the third receiving antenna 1212 and the fourth antenna position information of the fourth receiving antenna 1213, receive the third time transmitted by the third receiving antenna 1212 and the fourth time transmitted by the fourth receiving antenna 1213, determine the second time difference between the third time and the fourth time, and determine the second position information based on the third antenna position information, the fourth antenna position information and the second time difference.

[0192] In practice, the second transmitting antenna 1211 is responsible for sending a pulse signal to the remote control device 110. This pulse signal can be a brief electromagnetic wave or radio signal, used to trigger a response from the remote control device 110.

[0193] The third receiving antenna 1212 receives the feedback signal from the remote control device 110 based on the pulse signal and records the third time when the feedback signal is received. This means that when the remote control device 110 receives the pulse signal, it sends a feedback signal, which is received by the third receiving antenna 1212, and the time is recorded.

[0194] The fourth receiving antenna 1213 is similar to the third receiving antenna 1212; it also receives the feedback signal from the remote control device 110 based on the pulse signal, but records the fourth time the feedback signal is received. This means that if the third receiving antenna 1212 and the fourth receiving antenna 1213 are located in different positions, they may receive the same feedback signal at different times.

[0195] The second positioning communication chip 1214 acquires the position information of the third receiving antenna 1212 and the fourth receiving antenna 1213 (i.e., the position information of the third antenna and the position information of the fourth antenna). Then, it receives the reception times (third time and fourth time) transmitted by the third receiving antenna 1212 and the fourth receiving antenna 1213, and determines the difference between these two times (the second time difference). Based on this information (antenna positions and time difference), the second positioning communication chip 1214 can determine the position of the display device (i.e., the second position information).

[0196] By measuring the time difference of receiving the same signal at two different locations (the third receiving antenna 1212 and the fourth receiving antenna 1213) and combining the information from these two locations, high-precision positioning of the display device can be achieved, thereby ensuring the accuracy of the position of the indicator point on the display device.

[0197] In some embodiments, such as Figure 5As shown, the first pin of the second positioning communication chip is used to receive a power supply signal. The second, third, fourth, and fifth pins of the second positioning communication chip are respectively connected to the spatial information receiving unit. The sixth pin of the positioning communication chip is grounded. The seventh pin of the second positioning communication chip is connected to the second transmitting antenna. The eighth pin of the second positioning communication chip is connected to the third receiving antenna. The ninth pin of the second positioning communication chip is connected to the fourth receiving antenna.

[0198] In practice, the first pin of the second positioning communication chip is used to receive power supply signals to ensure that the second positioning communication chip can work normally.

[0199] Pins 2, 3, 4, and 5 are connected to the spatial information receiving unit. This connection allows the second positioning communication chip to receive data from the spatial information receiving unit, which is typically used to determine the device's location. Pin 6 is grounded to provide a stable reference potential, helping to protect the circuitry from electrostatic discharge (ESD) and other electrical interference.

[0200] Furthermore, the second positioning communication chip can transmit signals using a second transmitting antenna via its seventh pin. The eighth pin of the second positioning communication chip is connected to a third receiving antenna. This connection allows the positioning chip to receive signals via the third receiving antenna. The ninth pin of the second positioning communication chip is connected to a fourth receiving antenna. Similar to the eighth pin, this connection provides another way to receive signals, increasing the device's communication capabilities and flexibility.

[0201] This improves the performance, reliability, and flexibility of the second positioning and communication chip, thereby meeting the requirements for high-precision positioning and communication capabilities.

[0202] For example Figure 5As shown, pin 1 (the first pin) of the UltraWide Band (UWB) positioning chip U2 (the second positioning communication chip) is powered by a 3.3V supply voltage (3V3_UWB), with a series ferrite bead L1 and a ground bypass capacitor C4 for power filtering. Pins 2-5 (the second, third, fourth, and fifth pins) are the Serial Peripheral Interface (SPI), and pin 6 (the sixth pin) is grounded. Pin 7 (the seventh pin) is connected to the transmitting antenna through a ground impedance matching inductor L4, a series capacitor C9, and a ground impedance matching capacitor C11. Pin 8 (the eighth pin) is connected to the third receiving antenna through a ground impedance matching inductor L3, a series capacitor C5, and a ground impedance matching capacitor C18. Pin 9 (the ninth pin) is connected to the fourth receiving antenna through a ground impedance matching inductor L2, a series capacitor C2, and a ground impedance matching capacitor C3.

[0203] In some embodiments, such as Figure 23 As shown, the spatial information receiving unit 122 includes: a second Bluetooth antenna 1221, a second Bluetooth main control chip 1222, and a microcontroller subunit 1223;

[0204] The second Bluetooth antenna 1221 is configured to receive attitude information and first position information sent by the remote control device 110;

[0205] The second Bluetooth master control chip 1222 is configured to receive attitude information and first position information sent by the second Bluetooth antenna 1221;

[0206] The microcontroller subunit 1223 is configured to: receive attitude information and first position information sent by the second Bluetooth master control chip 1222, and receive second position information sent by the position information acquisition unit 121; determine the relative position information between the display device and the remote control device 110 based on the first position information and the second position information; and determine the position of the indicator point displayed on the display device according to the attitude information and the relative position information, so as to remotely control the display device based on the position of the indicator point.

[0207] In a specific implementation, the second Bluetooth antenna 1221 is a spatial information receiving unit 122 used specifically to receive wireless signals from the remote control device 110. These signals include the attitude information of the remote control device 110 (such as tilt angle, rotation direction, etc.) and the first position information (i.e., the absolute position of the remote control device 110 in space).

[0208] The second Bluetooth master control chip 1222 is a chip that handles Bluetooth communication. It is responsible for receiving signals captured by the second Bluetooth antenna 1221 and extracting the attitude information and first position information from them. Bluetooth technology is used here as a wireless communication method, enabling the remote control device 110 and the display device to transmit data without a physical connection.

[0209] The microcontroller subunit 1223 receives attitude information and first position information from the second Bluetooth master control chip 1222, and also receives second position information sent from the position information acquisition unit 121. Using this information, the microcontroller subunit 1223 determines the relative positional relationship between the remote control device 110 and the display device, and then dynamically determines the position of an indicator point on the display device based on the attitude information of the remote control device 110 and this relative position information.

[0210] By combining posture information and relative position information, the user's intention can be determined more accurately, thereby more precisely locating the indicator point on the display device and reducing the possibility of misoperation.

[0211] Furthermore, since the location of the indicator point is determined based on the real-time attitude and relative position information of the remote control device, users can move the remote control device 110 freely in a larger space, instead of being limited to a fixed position near the display device, which increases the flexibility of operation.

[0212] In some embodiments, such as Figure 24 As shown, the microcontroller subunit includes: a microcontroller chip;

[0213] The first pin of the microcontroller chip is used to receive a power supply signal, the second and third pins of the microcontroller chip are grounded, and the other pins of the microcontroller chip, except for the first, second and third pins, are connected to the position information acquisition unit.

[0214] In practical implementation, the first pin of the microcontroller chip is used to receive the power supply signal, ensuring the chip's normal operation. The second and third pins are grounded to provide a stable potential reference, ensuring stable voltage and current in the circuit. Besides the pins used for power supply and grounding, the other pins of the microcontroller chip are connected to the position information acquisition unit. These can be used for data transmission, command reception, and other functions. Furthermore, they can be connected to peripheral units set up in the remote control circuit. This ensures efficient and reliable communication between the microcontroller subunit and the position information acquisition unit.

[0215] For example Figure 24As shown, pin 1 (pin 1) of the microcontroller unit (MCU) U4 is powered by a 3.3V power supply (VCC3V3) and connected to two bypass capacitors C13 and C12 for power filtering. Pins 2 (pin 2) and 3 (pin 3) are grounded. Other general purpose input / output (GPIO) interfaces (i.e., other pins) are used to connect other unit circuits, which may be position information acquisition units and / or peripheral units.

[0216] In some embodiments, such as Figure 23 As shown, the remote control circuit also includes: peripheral units, which include, but are not limited to: flash memory (FLASH), light-emitting diodes (RGB LED), infrared receivers (IR), ambient light sensors, and Universal Serial Bus (USB) interfaces.

[0217] The circuit connection diagram of the infrared receiver tube is as follows: Figure 25 As shown, U1 is an infrared receiver tube. Pin 1 is connected to the Bluetooth SoC through pull-up resistor R1 and series resistor R2. Pin 2 is grounded. Pin 3 is powered by a 3.3V power supply terminal (VCC3V3) and connected to a ground capacitor C1 for power filtering.

[0218] In addition, such as Figure 23As shown, the wireless communication unit (i.e., the spatial information receiving unit) includes a microcontroller unit (MCU), a Bluetooth SoC (i.e., the second Bluetooth master control chip), and a BT antenna (i.e., the second Bluetooth antenna). The MCU is the master control chip and is connected to the Bluetooth SoC via an asynchronous transceiver (UART). The BT antenna is connected to the Bluetooth SoC and is responsible for transmitting and receiving electromagnetic waves. The Bluetooth SoC transmits data to the MCU via a serial port. The wireless positioning unit consists of an ultra-wideband (UWB) chip (i.e., the second positioning communication chip), a transmitting antenna (i.e., the second transmitting antenna), a first receiving antenna (i.e., the third receiving antenna), and a second receiving antenna (i.e., the fourth receiving antenna). The ultra-wideband (UWB) chip has a built-in positioning algorithm and can obtain coordinate position information (i.e., the second position information). The UWB chip is connected to the MCU via a synchronous serial communication bus (Serial Peripheral Interface, SPI) and sends the position information to the MCU. The peripheral unit includes a FLASH, an RGB LED, an IR receiver, an ambient light sensor, and a USB interface. The FLASH is connected to the MCU via the SPI bus and can store data information. The LED is connected to the MCU to indicate the operating status. An IR receiver is also connected to the MCU to receive infrared signals from the remote control's IR transmitter, decode them, and send them to the MCU. An ambient light sensor is connected to the MCU via an analog-to-digital converter (ADC) to acquire ambient brightness, convert it into an analog voltage, and send it to the MCU to adjust the screen brightness. A USB interface connects to the MCU, enabling data interaction between the MCU and the display screen.

[0219] Based on the same inventive concept, such as Figure 26 As shown, embodiments of this application propose a remote control method for a display device, applicable to a remote control system for a display device according to any of the above embodiments. The remote control system includes a remote control device and a remote control circuit disposed in the display device. The method includes:

[0220] Step 2601: Obtain the attitude information and first position information of the remote control device, and the second position information of the display device.

[0221] Step 2602: Determine the relative position information between the display device and the remote control device based on the first position information and the second position information, and determine the position of the indicator point displayed on the display device according to the attitude information and the relative position information, so as to remotely control the display device based on the position of the indicator point.

[0222] In practice, attitude information refers to the direction or orientation of the remote control device in space, which is usually obtained through built-in sensors (such as gyroscopes, accelerometers, etc.).

[0223] The first location information refers to the specific location of the remote control device in space, which can be obtained through Bluetooth positioning, built-in positioning communication chip (Ultra-Wide Band, UWB) or other indoor positioning technologies (such as infrared, ultrasonic, radio frequency identification RFID, etc.).

[0224] The second location information refers to the position of the display device in space, which can also be obtained through the aforementioned positioning technology.

[0225] Based on the first position information of the remote control device and the second position information of the display device, the relative positional relationship between them, such as distance and direction, is determined.

[0226] By combining the attitude and relative position information of the remote control device, the location of the indicator point to be displayed on the display device is determined. This indicator point can be a cursor, a highlighted area, or an arrow pointing to a specific object, etc.

[0227] The process of further determining the position of an indicator point on the display device based on attitude information and relative position information is as follows:

[0228] A pre-established database mapping attitude and relative position information to the position of the indicator point on the display device is used. The position of the indicator point on the display device is obtained by searching this database based on the attitude and relative position information.

[0229] Users can change the position of the indicator point by moving the remote control and execute commands related to the current position of the indicator point through specific operations (such as pressing a button). Users do not need to remember complex button combinations; they can control the device simply by moving it. Furthermore, by combining attitude information and relative position information, more precise control can be achieved.

[0230] The remote control system architecture diagram of the display device in this application is as follows: Figure 27As shown, the system includes a display screen (i.e., a display device), a receiver (i.e., a remote control circuit), and a remote controller (i.e., a remote control device). The receiver is mounted on the display screen and connected to it via a Universal Serial Bus (USB). The remote controller interacts with the receiver wirelessly. The receiver has a wireless communication unit (i.e., a wireless positioning unit, i.e., a position information acquisition unit) and peripheral units. The remote controller has a wireless communication unit (i.e., a spatial information receiving unit), a wireless positioning unit (i.e., a position information acquisition subunit), an inertial measurement unit (i.e., an attitude information acquisition subunit), a power management unit (i.e., a power supply management unit), and peripheral units. The two wireless communication units can communicate with each other. The inertial measurement unit of the remote controller can acquire the attitude information of the remote controller and send it to the receiver through the wireless communication unit. The wireless positioning unit of the receiver communicates with the wireless positioning unit of the remote controller to obtain the coordinate position information of the remote controller. The receiver uses the coordinate position information and attitude information to determine the direction the remote controller is pointing, and then displays the pointing point on the display screen.

[0231] This application enables that whenever and wherever the remote control is picked up in front of the display device, as long as the remote control is pointed at the display device, the cursor (i.e., the indicator point) will immediately appear in the pointing direction. This solves the problems of cumbersome operation of traditional remote controls and inaccurate pointing of relative pointing remote controls, achieves absolute positioning, and improves the user experience.

[0232] Through the above scheme, the remote control device can capture its attitude information and first position information in real time, and accurately match them with the second position information of the display device itself obtained by the remote control circuit to determine the relative position information between the two. Then, based on the attitude information and relative position information, the position of the indicator point displayed on the display device is determined. Thus, when the user points the remote control device at the display device, the display device can immediately display the indicator point that precisely corresponds to the direction pointed by the remote control device, realizing the convenient experience of pointing and controlling, and ensuring the user experience without cumbersome button operations.

[0233] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

Furthermore, the apparatus may be shown in block diagram form to avoid obscuring the embodiments of this application, and this also takes into account the fact that the details of the implementation of these block diagram apparatuses are highly dependent on the platform on which the embodiments of this application will be implemented (i.e., these details should be fully understood by those skilled in the art).
