[0023] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] Reference Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of the first embodiment of the environment perception control system of the present invention. Figure 1 As shown, in this embodiment, the environment perception control system includes: a sensor acquisition unit 10, a main control unit 20 and a backlight driving module 30. The sensor acquisition unit 10 is connected to a first end of the main control unit 20, and a second end of the main control unit 20 is connected to the backlight driving module 30.

[0028] It should be noted that the sensor acquisition unit 10 can be used to collect the ambient temperature and ambient humidity of the display device, generate temperature and humidity data information, and transmit the temperature and humidity data information to the main control unit; the main control unit 20 can be used to determine the type of environment in which the display device is located based on the temperature and humidity data information, and generate a drive control instruction when the environment type is determined to be a humid environment, and transmit the drive control instruction to the backlight drive module; the backlight drive module 30 can be used to increase the backlight power according to the drive control instruction.

[0029] It should be understood that the sensor acquisition unit 10 may include a temperature sensor, a humidity sensor, and a data processor. The temperature sensor is used to generate an electrical signal amplitude corresponding to the temperature in response to the ambient temperature, and the humidity sensor is used to generate an electrical signal amplitude corresponding to the humidity in response to the ambient humidity. The data processor can filter the electrical signal amplitude and other processing to generate the temperature and humidity data information, and the temperature and humidity data information includes both the ambient temperature and the ambient humidity. When applied to a display device, the sensor acquisition unit 10 can be set on the outer side of the lower end casing of the display device to facilitate the detection of the temperature and humidity of the air around the display device.

[0030] It should be noted that the sensor acquisition unit 10 can be connected to the main control unit through the I2C bus for data transmission interaction. The main control unit 20 can be an electronic device with data caching and processing capabilities, such as a central processing unit (CPU) or a microcontroller unit (MCU). The type of environment in which the display device is located can be determined based on the temperature and humidity data information. For example, when the ambient temperature exceeds a temperature threshold (for example, it can be set to 20 degrees Celsius) and the ambient humidity exceeds a humidity threshold (for example, it can be set to 85%), it is determined to be an environment type that is prone to equipment corrosion.

[0031] Furthermore, multiple temperature thresholds and humidity thresholds may be set to construct multiple different environment types, so as to more accurately determine the external environment in which the device operates. The numerical settings of the temperature threshold and the humidity threshold are not specifically limited in this embodiment.

[0032] It should be understood that the drive control instruction can be a power adjustment instruction issued to the controlled backlight drive module, and the main control module adjusts the backlight drive module to dynamically maintain the offset of the backlight power increase by issuing the drive control instruction. Among them, the environment confirmation algorithm and the corresponding control mode pre-set in the main control unit 20, the value of the backlight drive module power offset can be adjusted according to the temperature and humidity data information collected in real time.

[0033] It should be noted that the backlight drive module can be a functional circuit for backlight control and adjustment in a display device, which can provide a light source for the display device. The display device can adjust the backlight heat generation by adjusting the power during operation. The power adjustment can be achieved by adjusting the offset of the PWM wave duty cycle increase. When the PWM wave duty cycle increases, the backlight power of the backlight drive module increases, thereby increasing the backlight heat generation to achieve short-term heating and dehumidification of the display screen, improve the humidity state of the display screen module, and reduce local humidity. The drive control instruction can be an electrical signal with adjustable amplitude. The backlight drive module adjusts the offset of the PWM wave duty cycle according to the amplitude of the electrical signal of the drive control instruction.

[0034] Furthermore, the main control unit can also be used to start timing when determining that the environment type is a humid environment, and after the timing reaches a first preset time, the main control unit stops transmitting the drive control instruction to the backlight drive module. The first preset time can also be adjusted according to the temperature and humidity data information.

[0035] It should be noted that the environment perception control system may further include: a data storage unit 40 ; the data storage unit is connected to the third end of the main control unit 20 .

[0036] The main control unit 20 may also be used to transmit the temperature and humidity data information to the data storage unit 40; the data storage unit 40 may be used to encrypt the temperature and humidity data information, and store the encrypted temperature and humidity data information in association with a sampling time.

[0037] It should be understood that the sampling time can be the interval between each startup, that is, the temperature and humidity data information will be stored every time the display device is powered on, and it can also be set to the first startup of each day. At the same time, the sampling time will be associated and stored to facilitate fault analysis during the debugging phase. The temperature and humidity data information can be stored in the memory of the display device. When a display failure occurs in the device, the encrypted information of the past ambient temperature and humidity of the device during the startup time can be checked in a special maintenance mode in a local fault diagnosis mode (alternative maintenance point). This type of information is converted by a dedicated decryption device that is strictly authorized for internal use, and is used for auxiliary statistical analysis of the cause of the failure, while avoiding the risk of user information leakage.

[0038] Among them, when storing temperature and humidity data information, the data in the information can be classified and converted into codes for storage. For example, when the temperature is in the range of -60℃ to -55℃, the corresponding code is T1, when it is in the range of -55℃ to -50℃, the corresponding code is T2, and when it is in the range of -50℃ to -45℃, the corresponding code is T3. According to this rule, the corresponding code is T11 in the range of 0℃ to 5℃ until the temperature test upper limit is 70℃ to 75℃, which corresponds to T23. Similarly, when the humidity is in the range of 0% to 5%, the corresponding code is H1, when it is in the range of 5% to 10%, the corresponding code is H2, and when it is in the range of 10% to 15%, the corresponding code is H3. According to this rule, the corresponding code is H11 in the range of 50% to 55%, until the corresponding code is H20 in the range of 95% to 100%, which is the upper limit of the temperature test. The conversion of the above data and codes can be set according to actual needs.

[0039] Further, the temperature and humidity data information can be encrypted by encoding the temperature value and humidity value in the temperature and humidity data information into a packaged data structure (such as a JSON structure), and the binary data of the temperature value and the humidity value are included and the checksum is added to set the corresponding code length. The encapsulated data structure is encrypted with the public key to generate ciphertext information, and the private key corresponding to the public key is used for decryption. When the user's display device fails, the maintenance personnel decrypt the above ciphertext information with the private key to obtain the plain text of the temperature and humidity data information. At the same time, the encapsulated data structure can also be encapsulated with the sampling time of the corresponding temperature and humidity data information, and the sampling time and the temperature and humidity data information are format-converted and encapsulated into an encapsulated data structure. The sampling time can also be stored as the timestamp of the ciphertext information generated by the public key encryption, that is, the sampling time is not encrypted, and the timestamp of the ciphertext information after the temperature and humidity data information is encrypted corresponds to the sampling time of the temperature and humidity data information. In the after-sales service link, the device can be authorized to read the encrypted data, and the various fault-related factors can be judged in the form of fault classification codes.

[0040] In this embodiment, the environment perception control system includes: a sensor acquisition unit, a main control unit and a backlight driving module; the sensor acquisition unit is connected to a first end of the main control unit, and a second end of the main control unit is connected to the backlight driving module; the sensor acquisition unit is used to acquire the ambient temperature and ambient humidity of the display device, generate temperature and humidity data information, and transmit the temperature and humidity data information to the main control unit; the main control unit is used to determine the type of environment in which the display device is located according to the temperature and humidity data information, generate a drive control instruction when the environment type is determined to be a humid environment, and transmit the drive control instruction to the backlight driving module; the backlight driving module is used to increase the backlight power according to the drive control instruction, increase the backlight heat generation to reduce the local humidity of the display screen, improve the moisture corrosion condition, and improve the reliability and service life of the display screen.

[0041] In addition, in order to achieve the above-mentioned purpose, an embodiment of the present invention also proposes a display device. Since the display device includes an environmental perception control system as mentioned above, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments. For the same or similar contents as those in the above-mentioned embodiments, please refer to the above introduction and will not be repeated later.

[0042] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of the structure of a first embodiment of a display device according to the present invention. Figure 2 As shown, in this embodiment, the display device includes a display screen 50 and an environment perception control system 100, and the display screen 50 is connected to a main control unit 20 in the environment perception control system.

[0043] It should be noted that the main control unit 20 can be used to transmit the temperature and humidity data information collected by the sensor acquisition unit to the display screen 50 when the display device is turned on; the display screen 50 can be used to push a first UI interface containing the temperature and humidity data information in a preset display area.

[0044] It should be understood that when the display device is turned on, the sensor acquisition unit 10 in the environmental perception control system 100 will be driven to collect temperature and humidity data information and transmit it to the display screen through the main control unit 20. The display screen pushes the first UI interface to display the real-time temperature and humidity data of the environment in the preset display area, which can remind the user to intervene in the ambient temperature and humidity. The sensor acquisition unit 10 can be located on the lower front face of the display device housing. The main control unit 20 and the backlight drive module 30 can both be set on the internal movement board of the display device. The first UI interface can also include a switch option space for backlight control and energy-saving settings, which can realize the turning off and on of the temperature compensation function in the display device. Refer to Figure 3 , Figure 3 It is a schematic diagram of the first UI interface in the first embodiment of the display device of the present invention.

[0045] Furthermore, the display device further comprises: a remote control transceiver unit 60; the remote control transceiver unit 60 is connected to the main control unit 20, and the remote control transceiver unit 60 is also connected to a remote controller by wireless communication.

[0046] It should be noted that the remote control transceiver unit 60 can be used to receive the wireless control signal of the remote control, generate an information call instruction, and transmit the information call instruction to the main control unit 20; the main control unit 20 can also be used to transmit the temperature and humidity data information collected by the sensor acquisition unit to the display screen when receiving the information call instruction.

[0047] It should be understood that the wireless control signal can be a display device control signal sent by the wireless transmitter of the remote control when the user presses a button set on the remote control, and the information call instruction can be an instruction for the display device to parse the wireless control signal and perform a corresponding function according to the wireless control signal. In this embodiment, it can be a temperature and humidity call instruction. The user can manually call out the multiplexing method of the remote control to realize the call and viewing of temperature and humidity information. The home button can be used to call out the home page information page, and the temperature and humidity information will be displayed in the information bar. When the home page is closed or switched to other pages, this type of information will disappear.

[0048] Furthermore, in the first UI page, when the main control unit determines the type of environment in which the display device is located based on the temperature and humidity data information, a blue background is used for prompting when the environment type is determined to be a non-humid environment. When the environment type is determined to be a humid environment, a yellow background is used for prompting. At the same time, a prompt can be given: the ambient humidity is high, and the device is about to start the timed dehumidification mode. In addition, the second UI interface can be set to include a prompt and an option control for selecting execution. The user can choose whether to execute the backlight module power control for dehumidification through the wireless control signal output by the remote control. Reference Figure 4 , Figure 4 It is a schematic diagram of the second UI interface in the first embodiment of the display device of the present invention.

[0049] In this embodiment, the display device includes a display screen and an environmental perception control system; the display screen is connected to a main control unit in the environmental perception control system; the main control unit is used to transmit the temperature and humidity data information collected by the sensor acquisition unit to the display screen when the display device is turned on; the display screen is used to push a first UI interface containing the temperature and humidity data information in a preset display area. The display device also includes: a remote control transceiver unit; the remote control transceiver unit is used to receive a wireless control signal from a remote control, generate an information call instruction, and transmit the information call instruction to the main control unit; the main control unit is also used to transmit the temperature and humidity data information collected by the sensor acquisition unit to the display screen when receiving the information call instruction. The temperature and humidity information that can be called out by the power-on and remote control can remind the user to make judgments and environmental intervention actions, thereby further achieving the purpose of protecting the device.

[0050] In addition, in order to achieve the above-mentioned purpose, the embodiment of the present invention also proposes a display device perception control method, referring to Figure 5 , Figure 5 FIG. 1 is a flow chart of an embodiment of a display device perception control method of the present invention. Figure 5 As shown, in this embodiment, the display device perception control method includes:

[0051] Step S01: collecting the ambient temperature and humidity of the display device to generate temperature and humidity data information.

[0052] It should be noted that a temperature sensor, a humidity sensor and a data processor can be used. The temperature sensor is used to generate an electrical signal amplitude corresponding to the temperature in response to the ambient temperature, and the humidity sensor is used to generate an electrical signal amplitude corresponding to the humidity in response to the ambient humidity. The data processor can filter the electrical signal amplitude and perform other processing to generate the temperature and humidity data information, which includes both the ambient temperature and the ambient humidity.

[0053] Step S02: Compare the amplitude of the temperature and humidity data information with the temperature and humidity threshold value.

[0054] It should be noted that by comparing the amplitude of the collected temperature and humidity data information with the preset temperature and humidity thresholds, the type of environment in which the display device is located can be determined. The temperature and humidity thresholds can be pre-set temperature values ​​and humidity values ​​for determining the condition prone to corrosion. For example, when the ambient temperature exceeds a temperature threshold (for example, it can be set to 20 degrees Celsius) in the temperature and humidity data information, and when the ambient humidity exceeds a humidity threshold (for example, it can be set to 85%), it is determined to be a humid environment type where equipment corrosion is prone to occur. Furthermore, multiple temperature thresholds and humidity thresholds can also be set to construct a variety of different environment types to more accurately determine the external environment in which the device is operating.

[0055] Step S03: when the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold, increasing the backlight power of the backlight driving module.

[0056] It should be noted that the backlight drive module can be an optoelectronic component applied to a liquid crystal display, which is composed of an LED light source, a reflector, a light guide strip, and an auxiliary structure to provide backlight illumination for the display device. A power adjustment command can be issued to the controlled backlight drive module to increase the backlight power, increase the backlight heat generation, and reduce the humidity of the display device. When the environment confirmation algorithm and the corresponding control mode are pre-set in the display device, the value of the backlight drive module power offset can be adjusted according to the temperature and humidity data information collected in real time, and the offset of the backlight power increase can be dynamically maintained. When the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold, the display screen can be heated and dehumidified by increasing the backlight heat generation to improve the humidity state in the display screen.

[0057] Furthermore, after step S01, it may also include: converting the ambient temperature and the ambient humidity in the temperature and humidity data information into an encapsulated data structure; using the sampling time of the temperature and humidity data information as a public key and the encapsulated data structure to generate ciphertext information. To facilitate fault analysis during the debugging phase, the temperature and humidity data information can be stored in the memory of the display device. When a display failure occurs in the device, the encrypted information of the past ambient temperature and humidity of the device during the power-on time can be checked in a special maintenance mode in a local fault diagnosis mode (alternative maintenance point). This type of information is converted using a dedicated decryption device that is strictly authorized for internal use, and is used for auxiliary statistical analysis of the cause of the failure, while avoiding the risk of user information leakage.

[0058] It should be noted that the temperature and humidity data information can be encrypted by encoding the temperature value and humidity value in the temperature and humidity data information into a packaged data structure (such as a JSON structure), and the binary data of the temperature value and humidity value are included and the checksum is added to set the corresponding code length. The data structure after encapsulation is encrypted with the public key to generate ciphertext information, and the private key corresponding to the public key is used for decryption. When the user's display device fails, the maintenance personnel decrypt the above ciphertext information with the private key to obtain the plain text of the temperature and humidity data information. At the same time, the encapsulated data structure can also be encapsulated with the sampling time of the corresponding temperature and humidity data information, and the sampling time and the temperature and humidity data information are format-converted and encapsulated into an encapsulated data structure. The sampling time can also be stored as the timestamp of the ciphertext information generated by the public key encryption, that is, the sampling time is not encrypted, and the timestamp of the ciphertext information after the temperature and humidity data information is encrypted corresponds to the sampling time of the temperature and humidity data information.

[0059] In this embodiment, temperature and humidity data information is generated by collecting the ambient temperature and ambient humidity of the display device; the amplitude of the temperature and humidity data information is compared with the temperature and humidity threshold; when the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold, the backlight power of the backlight drive module is increased, the backlight heat is increased, the humidity of the display device is reduced, the local humidity of the display screen is reduced, the moisture corrosion condition is improved, and the reliability and service life of the display screen are improved.

[0060] Based on the first embodiment of the display device perception control method of the present application, in the second embodiment of the display device perception control method of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 6 , Figure 6 A flow chart of Embodiment 2 of the display device perception control method of the present application is provided. After step S10, the display device perception control method further includes:

[0061] Step S601: Acquire a wireless control signal from a remote controller.

[0062] It should be noted that the wireless control signal can be a display device control signal sent by the wireless transmitter of the remote control when the user presses a button set on the remote control, and the display device can perform corresponding functions according to the wireless control signal. In this embodiment, it can be a temperature and humidity call function, and the user can manually call out the multiplexing method of the remote control to realize the call and viewing of temperature and humidity information.

[0063] Step S602: when the code of the wireless control signal corresponds to a key trigger code for the remote controller temperature and humidity calling function, the temperature and humidity data information corresponding to the key trigger code is obtained.

[0064] It should be understood that the wireless control signal for communication between the remote control and the display device can realize the transmission of information through signal encoding. The user can change the format of the code in the wireless control signal by pressing the function button or button combination set on the remote control. The display device reads whether the code in the wireless control signal contains a button trigger code according to the pre-set decoder. If so, it means that the button corresponding to the temperature and humidity call function is triggered. If not, it means that the temperature and humidity data do not need to be called at this time. When the button or button combination of the temperature and humidity call function on the remote control is triggered, it is determined that the user needs to view the temperature and humidity data information at this time. The display device includes a processor for data processing and analysis functions and a memory for data storage functions. The temperature and humidity data information collected by the sensor can be stored in the memory and called when the processor receives the button trigger code.

[0065] Step S603: Use the ambient temperature and ambient humidity in the temperature and humidity data information to fill in the first UI interface, and push the first UI interface to a preset display area of ​​the display screen for display.

[0066] It should be noted that the ambient temperature and ambient humidity can be filled in the first UI page for display, refer to Figure 3 The page design of the first UI page in . It is also possible to use a blue background to prompt when the environment type is judged to be a non-humid environment based on the comparison result of the temperature and humidity data information with the temperature and humidity threshold. When the environment type is judged to be a humid environment, a yellow background is used for prompting. You can also use the home button to call out the home information page, and the temperature and humidity data information will be displayed in the information bar of the home information page. When the home page is closed or switched to other pages, this information will disappear.

[0067] It should be understood that step S30 may also include: when the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold value, pushing the second UI interface including the dehumidification mode start selection control to the preset display area of ​​the display screen for display; obtaining the wireless control signal of the remote control, and when the code in the wireless control signal corresponds to the trigger code including the dehumidification mode start selection control, increasing the duty cycle of the PWM wave of the backlight drive module to the target duty cycle; using the PWM wave with the target duty cycle to drive the backlight drive module to operate according to the increased target backlight power.

[0068] It should be noted that when the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold, when it is determined that the environment type of the display device is a humid environment, a prompt can be given: "The ambient humidity is high, and the device is about to start the timed dehumidification mode." In addition, the second UI interface can also be set to include a prompt and a dehumidification mode start selection control for selection (refer to Figure 4The user can select the start and exit controls in the remote control to execute the backlight module power control for dehumidification through the buttons of the remote control, and the remote control outputs a wireless control signal containing the trigger code of the dehumidification mode start selection control to the processor of the display device.

[0069] It should be understood that, similar to the above-mentioned viewing method of temperature and humidity data information, the wireless control signal can also realize the selection and confirmation function of the control on the second UI interface by signal coding. The second UI interface includes prompts and option controls for selecting execution. The user can select the target option control (start or exit) by pressing the function button set on the remote control. The remote control changes the format of the code in the wireless control signal according to the triggering method of the function button. The display device reads the code in the wireless control signal according to the pre-stored decoder, determines whether the start or exit control is triggered, and then determines whether the user starts the dehumidification mode or exits the dehumidification mode. When the start control in the dehumidification mode start selection control is triggered by confirmation, it is confirmed that the user chooses to enter the dehumidification mode.

[0070] Increasing the backlight power of the backlight drive module can be achieved by adjusting the offset of the PWM wave duty cycle increase, the PWM wave duty cycle is increased to the target duty cycle, and the PWM wave of the target duty cycle is used to drive the backlight drive module to work according to the increased target backlight power, thereby increasing the backlight heat generation to achieve short-term heating and dehumidification of the display screen and reduce local humidity. It can also be that the environmental confirmation algorithm software and the corresponding control mode are pre-set in the memory of the display device, and the instructions for adjusting the power offset of the backlight drive module are generated according to the values ​​of the collected temperature and humidity data information, and the offset of the backlight power increase is dynamically maintained, and the display screen is heated and dehumidified by increasing the backlight heat generation to improve the humidity state in the display screen. In which, the target backlight power can be the working power required for heating and dehumidification, which can be set according to actual use requirements, and the target duty cycle can be the duty cycle of the PWM wave that drives the backlight drive module to work according to the target backlight power.

[0071] In this embodiment, by acquiring the wireless control signal of the remote control, when the code of the wireless control signal corresponds to the key trigger code containing the temperature and humidity calling function of the remote control, the temperature and humidity data information corresponding to the key trigger code is acquired; the ambient temperature and ambient humidity in the temperature and humidity data information are used to fill the first UI interface, and the first UI interface is pushed to the preset display area of ​​the display screen for display. When the amplitude of the temperature and humidity data information exceeds the temperature and humidity threshold, the second UI interface containing the dehumidification mode start selection control is pushed to the preset display area of ​​the display screen for display; the wireless control signal of the remote control is acquired, and when the code in the wireless control signal corresponds to the trigger code containing the dehumidification mode start selection control, the duty cycle of the PWM wave of the backlight drive module is increased to the target duty cycle; the PWM wave of the target duty cycle is used to drive the backlight drive module to work according to the increased target backlight power, thereby increasing the backlight heat and reducing the humidity of the display device. Through the temperature and humidity information that can be called out by the power-on and remote control, the user can be reminded to make judgments and environmental intervention actions, further achieving the purpose of protecting the device.
