Description

[0002] With the widespread adoption of smart TVs, smart displays, and other devices, natural human-computer interaction methods have become crucial for enhancing user experience. Gesture control, as an intuitive, contactless interaction technology, has been widely integrated into various display devices. Traditional gesture control schemes typically keep gesture recognition modules (such as cameras, infrared sensors, or millimeter-wave radar) constantly active, with their output signals being directly or continuously monitored and processed by the main processor. Continuous signal acquisition easily leads to false triggers; unconscious user actions (such as getting up or picking up an object) may be misinterpreted by the system as operational commands, interfering with normal use. Furthermore, for vision-based recognition schemes, continuous image acquisition raises serious concerns about user privacy and security. In addition, existing technologies that enable gesture functions via physical buttons or voice commands also suffer from inconvenience or failure in noisy environments.

[0023] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0024] Figure 1 This is a schematic diagram of the structure of a display device with gesture control according to an embodiment of the present invention.

[0025] This utility model discloses a display device with gesture control, including a display body and a remote control that wirelessly cooperates with the display body. Specifically, the remote control described in this utility model can be understood as an independent remote control module. This remote control module can be integrated into existing remote control devices, or it can be integrated into other devices in various ways or designed as an independent form. In specific implementation, it can be implemented according to the requirements.

[0026] The following sections describe the improved structures related to the display unit and the remote control. It should be noted that in the subsequent description, the "circuit module" structure involved in this embodiment actually refers to a hardware module built upon electronic components, utilizing circuit characteristics to perform its functions, and does not involve software processing or control. The "module" structure involved in this embodiment actually refers to an integrated unit with specific functions in the prior art. This embodiment only describes its connection with other structures; its internal implementation structure can be referenced from existing technologies.

[0027] To facilitate understanding, the relevant structures of the remote control will be described first in this embodiment of the utility model.

[0028] The remote control includes a touch sensor circuit module, a high-frequency oscillation circuit module, and an ASK superheterodyne transmission circuit module.

[0029] Figure 2 This is a schematic diagram of the touch sensor circuit module structure according to an embodiment of the present invention. The touch sensor circuit module is used to detect whether a user is touching the remote control, and generates an oscillation control signal when the user touches the remote control. In this embodiment of the present invention, the touch sensor circuit module includes an NPN transistor 104, a pull-up resistor 1033, a high-resistance base resistor 102, and a touch metal plate 101. In this embodiment of the present invention, the NPN transistor is selected as an S8050, and the resistance value of the high-resistance base resistor is 5.1MΩ.

[0030] Specifically, the emitter of the NPN transistor is grounded, and the collector is connected to the power supply through the pull-up resistor. This collector also serves as the oscillation control signal output terminal of the touch sensor circuit module. The base of the NPN transistor is connected to the touch metal plate through the high-resistance base resistor.

[0031] When the hand does not touch the metal plate, the transistor is cut off because the base is floating, and the collector outputs a high level; when the hand touches the metal plate, the AC signal induced by the human body turns the transistor on, and the collector outputs a low level.

[0032] Figure 3 This is a schematic diagram of the high-frequency oscillation circuit module structure according to an embodiment of the present invention.

[0033] The high-frequency oscillation circuit module includes an oscillation control signal input terminal 106 and an oscillation signal output terminal 107. The oscillation control signal input terminal is connected to the oscillation control signal output terminal of the touch sensor circuit module. Specifically, the high-frequency oscillation circuit module is controlled by the oscillation control signal. When the signal is valid, the high-frequency oscillation circuit module starts oscillating and generates a high-frequency oscillation signal with a specific frequency and waveform.

[0034] In this embodiment of the invention, the high-frequency oscillation circuit module consists of an oscillator chip CD4060 and an external 1MHz quartz crystal oscillator 105. The Reset pin of the oscillator chip CD4060 serves as the oscillation control signal input terminal of the high-frequency oscillation circuit module. When the Reset pin is high, the chip is reset and stops oscillating; when it is low (active), the chip starts working.

[0035] The CD4060 oscillator chip is equipped with a 1MHz crystal and its corresponding load capacitors (usually two 22pF capacitors, labeled C1 and C2 in the diagram), and operates in crystal oscillation mode. Internally, the CD4060 oscillator chip divides the 1MHz reference frequency, outputting a 62.5kHz (1MHz / 16) square wave signal from its Q4 pin (pin 7). This pin serves as the oscillation signal output terminal for the high-frequency oscillation circuit module.

[0036] Figure 4 This is a schematic diagram of the ASK superheterodyne transmitter circuit module structure according to an embodiment of the present invention.

[0037] The ASK superheterodyne transmitting circuit module is selected in conjunction with the ASK superheterodyne receiving circuit module within the display body, for example, both being 433MHz transceiver modules. In this embodiment of the invention, the ASK superheterodyne transmitting circuit module includes an oscillation signal input terminal, which is connected to the oscillation signal output terminal, for modulating the received 62.5kHz square wave signal onto a 433MHz carrier wave and broadcasting it externally.

[0038] Specifically, the 433MHz transmitter module has a power supply pin, a ground pin, a signal input pin, and an antenna pin, wherein the signal input pin is the oscillation signal input terminal 108.

[0039] The above describes the structure of the remote control according to an embodiment of this utility model. Specifically, after a human touches the touch metal plate, the remote control generates a 62.5kHz square wave signal loaded on a 433MHz carrier wave. It should be noted that the design purpose of this utility model embodiment is to avoid relying on conventional Bluetooth, infrared, or Wi-Fi connection methods between the display and the display body. Instead, it directly establishes an additional channel for transmitting human touch sensing information. Specifically, Bluetooth and other protocol pairing connection methods require a series of information processing steps, resulting in a certain delay in actual use. Infrared data transmission requires the remote control and the display body to be aligned, making it unsuitable for the application scenarios of this utility model embodiment. In specific implementation, the user generates an activation signal through touch, activating the signal transmission between the gesture recognition module and the processor module on the display body. This allows for the activation and deactivation of the gesture recognition module in a relatively imperceptible manner, preventing other user actions from being recognized by the gesture recognition module and causing incorrect control commands, thus affecting user experience.

[0040] Specifically, the display unit includes a gesture recognition module, a processor module, an ASK superheterodyne receiver module, a rectifier and filter circuit module, a signal conversion circuit module, and a signal path control circuit module. Essentially, these modules are connected sequentially, with the signal path control circuit module connected to the signal transmission lines of the gesture recognition module and the processor module. The specific connection method will be explained later.

[0041] Figure 5 This is a schematic diagram of the ASK superheterodyne receiver circuit module and rectifier filter circuit module according to an embodiment of the present invention.

[0042] Specifically, the ASK superheterodyne receiver circuit module is used to receive wireless signals from the remote controller and demodulate the wireless signals to output a demodulated signal containing a specific oscillation signal.

[0043] In this embodiment of the present invention, the module uses an ASK superheterodyne receiver module operating in the 433MHz frequency band, referred to as a 433MHz receiver module. Specifically, the 433MHz receiver module generally has a VCC pin (receiver positive pin), a GND pin (receiver ground pin), and a DATA / DOUT pin (receiver data output pin). Depending on the differences in the actual implementation structure, some 433MHz receiver modules also have an ANT pin. In this embodiment of the present invention, the Data pin / DOUT pin (receiver data output pin) is the demodulated signal output terminal 113 required by this embodiment of the present invention.

[0044] In practical applications, when a transmitter module paired with a 433MHz receiver module operates, the 433MHz receiver module captures a radio signal with a carrier frequency of 433MHz. Its internal circuitry first amplifies the radio signal at high frequency, then performs a series of superheterodyne processes such as mixing and intermediate frequency amplification, and finally performs ASK (Amplitude Shift Keying) demodulation. During demodulation, the 433MHz high-frequency carrier is removed, restoring the original baseband signal actually transmitted by the transmitter module. In this embodiment, the original baseband signal refers to the 62.5kHz square wave signal generated internally by the remote control. Ideally, the DATA pin of the 433MHz receiver module would output a corresponding 62.5kHz square wave voltage signal after demodulating the radio signal. However, in practical applications, because the demodulation process cannot completely remove noise and introduces some background noise, the output signal of the DATA pin is mixed with noise from the channel. Therefore, the output signal of the DATA pin is not the actual square wave voltage signal. For accuracy, this embodiment names it the demodulated signal containing the oscillation signal.

[0045] The rectifier and filter circuit module has a demodulated signal input terminal and a level signal output terminal, with the demodulated signal input terminal connected to the demodulated signal output terminal. The rectifier and filter circuit module is used to rectify and filter the demodulated signal, extracting the oscillation signal and converting it into a smooth and stable DC level signal.

[0046] In this embodiment of the invention, the rectifier-filter circuit module includes a rectifier diode 109, a filter capacitor 110, and a bleeder resistor 111. The positive terminal of the rectifier diode serves as the demodulation signal input terminal of the rectifier-filter circuit module, connected to the Data pin of the 433MHz receiver module. The negative terminal of the rectifier diode serves as the demodulation signal output terminal 112 of the rectifier-filter circuit module. One end of the filter capacitor is connected to the negative terminal of the rectifier diode, and the other end is grounded. Its function is to filter out high-frequency noise and store charge to smooth the voltage. One end of the bleeder resistor is connected to the negative terminal of the rectifier diode, and the other end is grounded. Its function is to provide a discharge circuit for the filter capacitor when there is no signal input, ensuring that the output level can fall back to a low level.

[0047] Specifically, when the DATA pin outputs a 62.5kHz square wave high-level pulse signal, the diode is forward biased and conducts. The high-level pulse signal flows through the diode and charges the subsequent filter capacitor. The diode only allows positive pulses to pass through and blocks negative current, thus achieving preliminary rectification. The filter capacitor is rapidly charged during the diode's conduction period, and the voltage across it rises rapidly. In actual implementation, due to the high frequency of the square wave (62.5kHz, with a period of approximately 16 microseconds), the capacitor quickly converts the intermittent pulses into a relatively stable DC voltage, thereby forming a stable high-level signal.

[0048] When the square wave output from the DATA pin is at a low level or during a pulse gap, and when the DATA pin returns to a low level, the anode voltage of the rectifier diode is lower than or equal to the cathode voltage, and the diode is in a reverse-biased cutoff state. At this time, the filter capacitor will be grounded through the parallel bleeder resistor, forming an RC discharge circuit, and will discharge rapidly. The filter capacitor will no longer generate a high-level signal after power loss.

[0049] The signal conversion circuit module includes a level signal input terminal and a control signal output terminal, with the level signal input terminal connected to the level signal output terminal. This signal conversion circuit module is used to perform waveform shaping and drive capability enhancement on the DC level signal, converting it into a clean, stable digital control signal with sufficient drive capability.

[0050] This utility model provides two specific implementations of signal conversion circuit modules for reference. The first implementation is a latch-based signal conversion circuit module, whose working logic is to maintain active output upon receiving a trigger signal. That is, when a human body touches the contact metal plate, the communication between the gesture recognition module and the processor module is activated, and the communication between the gesture recognition module and the processor module is maintained even after the human body removes the remote control. The second implementation is a transistor-based signal conversion circuit module, whose working logic is to be activated upon receiving a trigger signal and deactivated after the trigger signal disappears. That is, when a human body touches the contact metal plate, the communication between the gesture recognition module and the processor module is activated, and the communication between the gesture recognition module and the processor module is disconnected after the human body removes the remote control.

[0051] Signal conversion circuit module based on latch Figure 6 This is a schematic diagram of the signal conversion circuit module based on a latch, according to an embodiment of the present invention.

[0052] Specifically, the signal conversion circuit is based on an RS signal latch chip, which can be a CD4044. Specifically, the CD4044 has four independent RS latches, and this embodiment requires one set of latches. Each latch has a corresponding set terminal, reset terminal, output terminal, and tri-state control terminal. The latch's operating mechanism can be understood as follows: when the tri-state control terminal is active, the set terminal, after being triggered, continuously outputs a high-level signal; when the reset terminal is triggered, the output terminal continuously outputs a low-level signal.

[0053] The S pin (set terminal 113) of the latch serves as the level signal input terminal of this module and is connected to the output of the rectifier and filter module. Its Q pin (output terminal 115) serves as the control signal output terminal of this module. When the S pin receives a high level, the Q pin outputs and latches a high level. To further enhance the user experience, the R pin (reset terminal 114) of the latch can be connected to a manual reset module. This manual reset module can be a simple tactile switch; when the switch is pressed, the R pin is briefly grounded, thereby forcing the Q output to reset to a low level, allowing the user to actively disable the gesture function. Correspondingly, the manual reset module can be located on the remote control or on the display unit; this embodiment of the invention will not describe it further.

[0054] Transistor-based signal conversion circuit module Figure 7 This is a schematic diagram of the transistor-based signal conversion circuit module structure according to an embodiment of the present invention.

[0055] Specifically, the transistor-based signal conversion circuit module includes a transistor switching circuit and an inverter. The transistor switching circuit uses a common-emitter switching circuit. Specifically, the transistor switching circuit uses an NPN transistor (named the first NPN transistor 118, model S8050 can be selected). The base of the first NPN transistor is connected to a first base resistor 117 as a level signal input terminal 116 to receive the DC level signal from the rectifier and filter circuit module. The first collector of the first NPN transistor 118 is connected to the power supply through a first pull-up resistor 119, and the first emitter of the first NPN transistor 118 is grounded. The input terminal of the inverter 120 is connected to the collector, and the output terminal of the inverter is the control signal output terminal 121.

[0056] In actual implementation, when the input signal is high, the transistor is saturated and conducts, and its collector voltage is pulled down to close to 0V (about 0.2V), resulting in a low output level; when the input is low (0V), the transistor is reliably cut off, and its collector voltage is pulled up to VCC through the pull-up resistor, resulting in a high output level.

[0057] After the output signal of the collector is inverted by the inverter, the signal activation relationship between the input high level and the output high level is realized. It should be noted that the reason for using this transistor-based signal conversion circuit module instead of directly connecting the rectifier and filter circuit module to the signal path control circuit module is that this transistor-based signal conversion circuit module also has the functions of signal (voltage) amplification and signal holding. Specifically, the DC level signal is extracted from the demodulated signal and has limited strength. In order to ensure the stability of the signal path control circuit module, the control signal is first amplified by the transistor switching circuit, and then the full-amplitude level (0V or VCC) is output by the digital inverter, eliminating the problems of transistor saturation voltage drop and slow edge. In addition, the output stage of the inverter can provide strong source and sink current, which can quickly charge and discharge the control pin capacitor of the analog switch, ensuring rapid and reliable switching action.

[0058] (Refer to the attached diagram) Figure 1 As shown in the diagram, the signal path control circuit module includes a control signal input terminal, a main signal input terminal, and a main signal output terminal. Specifically, the control terminal of the signal path control circuit module receives digital control signals from the signal conversion circuit module, and its main signal path is connected in series between the signal output terminal of the gesture recognition module and the signal input terminal of the processor module. This module physically turns the main signal path on or off according to the level of the digital control signal.

[0059] In this embodiment of the invention, the core of the signal path control circuit module is an analog switch integrated chip, such as the CD4066. The control pin of this analog switch integrated chip is the control signal input terminal of this module. When the control signal is at an effective level (high level for the CD4066), the internal electronic switch closes, allowing the gesture signal to be transmitted from the main signal input terminal to the main signal output terminal; otherwise, the switch opens, and the signal path is physically isolated.

[0060] It should be noted that some electronic components involved in the display device of this embodiment need to operate under power supply. Accordingly, the corresponding power supply voltage VCC has been marked in the schematic diagram. In actual application, power is supplied according to the power supply voltage required by the components. The relevant structure of the power supply module will not be described separately in this embodiment.

[0061] In summary, this utility model embodiment provides a display device with gesture control. The display body of the display device has a gesture control module, which can be controlled by gestures. The communication between the gesture control module and the processor module is controlled by a signal path control circuit module, which is controlled by a specially designed circuit module. In actual use, the user triggers the gesture control module by touching the remote control, avoiding accidental control of the display body by gestures. In addition, the information from the user touching the remote control is transmitted at the hardware level through an independent channel, without relying on too many processor signal processing paths, making the signal transmission more reliable and faster, and providing good practicality. For gesture recognition modules using camera modules, the on-demand activation of the gesture recognition module also has a user privacy protection function.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
