[0002] At present, with the rapid development of science and technology, refrigerators, freezers and other refrigeration equipment all use display chips to drive light-emitting diodes to achieve constant current drive, brightness grading adjustment, etc. In specific applications, when refrigeration equipment is exposed to strong interference, the display of the refrigeration equipment will fail. There are two types of failures. The first type of failure can be automatically recovered, and the second type of failure cannot be automatically recovered. It can only be recovered when the refrigeration equipment is powered off and then powered on again. Therefore, how to achieve automatic recovery of display failures has become a technical problem that needs to be solved urgently.

[0003] The related art provides a liquid crystal display driving circuit, including a control register stack, a timing control module, an automatic refresh special register, a display buffer register, a bias voltage generating module and an electrode driving module. The input end of the control register stack is connected to the first output end of the main processor of the front end, the output end of the control register stack is connected to the input end of the timing control module, the first output end of the timing control module is connected to the first input end of the automatic refresh special register, the second output end of the timing control module is connected to the first input end of the electrode driving module, the second input end of the automatic refresh special register is connected to the second output end of the main processor of the front end, the output end of the automatic refresh special register is connected to the first input end of the display buffer register, the second input end of the display buffer register is connected to the third output end of the main processor of the front end, the output end of the display buffer register is connected to the second input end of the electrode driving module, the input end of the bias voltage generating module is connected to the external voltage signal, and the output end is connected to the third input end of the electrode driving module. The display buffer register receives display data and outputs the display data to the electrode driving module for generating an electrode driving signal. Among them, the display data includes two parts. One part is the display data of display elements that are refreshed regularly (such as second flashing dots and progress bars), which are loaded from the automatic refresh dedicated register, and the loading process is controlled by the timing control module; the other part is the display data of display elements that are refreshed irregularly (for example, digital characters or interfaces generated in response to specific operations), and the display data is directly written into the display buffer register by the front-end main processor, and the data reading and writing process is directly controlled by the main processor.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The related art configures an automatic refresh dedicated register on the liquid crystal display drive circuit. The automatic refresh dedicated register is a hardware module, and the automatic refresh dedicated register is controlled by a timing control module when refreshing display data. When the display data stored in the display buffer register is subject to external interference, the display data is modified, and the external interference is not periodic. Therefore, the timing control module is used to control the automatic refresh dedicated register to perform the refresh operation of the display data. There is a situation where the refresh operation is performed even when it is not needed, resulting in the occupation of hardware resources.

[0036] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0037] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0038] In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0039] The embodiment of the present disclosure provides a refrigeration device. The refrigeration device includes a device body and a display chip. The device body is configured with a main control board, and the display chip is configured with a configuration register. The main control board is used to control the control timing of the device body. The configuration register is used to store display data. Among them, the control timing includes the refrigeration operation and fault repair of the device body. The display data includes display elements. The display elements include part or all of a flashing point, a progress bar or a digital character.

[0040] In the refrigeration device provided by the embodiment of the present disclosure, the main control board and the display chip are independent of each other, and the main control board has the dual functions of controlling the control timing of the refrigeration device and refreshing the display data of the display chip. In this way, the embodiment of the present disclosure controls the refresh operation of the configuration register of the display chip through the main control board, and controls the configuration register to execute the refresh of the display data through software, thereby reducing the occupation of hardware resources and facilitating the improvement of the flexibility of the refresh operation of the configuration register of the display chip.

[0041] Based on the above refrigeration equipment, combined with Figure 1 As shown, the embodiment of the present disclosure provides an anti-interference method for a display chip, comprising:

[0042] S11, when the configuration register is initialized, the main control board obtains the configuration status of the configuration register.

[0043] S12, when the configuration state indicates that the configuration register updates data, the main control board sends a control instruction for executing a configuration register refresh operation to the display chip.

[0044] By using the anti-interference method for display chips provided by the embodiment of the present disclosure, when the configuration register of the display chip configuration is determined to be initialized using the main control board, the configuration status of the configuration register is obtained. When the configuration status indicates that the configuration register updates the data, it is determined that the configuration register has been modified due to external interference, causing the display data. At this time, it is necessary to perform a refresh operation of the configuration register to avoid abnormalities in the display chip under external interference. In this way, the embodiment of the present disclosure uses the software method of the main control board to monitor whether the configuration register display data has been modified, and performs a refresh operation of the configuration register when the modification is confirmed. It can reduce the occupation of hardware resources and at the same time, improve the flexibility of the refresh operation of the display chip configuration register.

[0045] Optionally, combined Figure 2 As shown, the main control board determines the configuration register update data in the following manner:

[0046] S21, the main control board obtains the display data of the configuration register at the current moment.

[0047] S22, the main control board obtains the reference display data of the configuration register, wherein the reference display data refers to the display data stored in the configuration register initialization stage.

[0048] S23, when the display data at the current moment does not match the reference display data, the main control board determines to update the configuration register data.

[0049] In this step, the display data does not match the reference display data, including: the display data is different from the reference display data. The display data matches the reference data, including: the display data is the same as the reference data.

[0050] In this way, when the display chip is not disturbed by external factors, the display data of the configuration register remains unchanged. However, when the display chip is disturbed by external factors, the data of the configuration register is updated. To this end, the embodiment of the present disclosure obtains the display data of the configuration register at the current moment in real time and matches it with the reference display data, and determines the configuration register update data when the two do not match, which is conducive to improving the flexibility of the display chip configuration register refresh operation.

[0051] In a specific embodiment, the main control board obtains the display data of the configuration register at the current moment, and the main control board can periodically obtain the display data of the configuration register at the current moment. The acquisition cycle configuration is set according to demand. In another specific embodiment, the main control board obtains the display data of the configuration register at the current moment, and the main control board can be set to different acquisition times of the display data, and the display data of the configuration register is sequentially obtained at the set acquisition times. For example, the main control board sets the acquisition times of the display data to be 18:00, 18:10, 18:30, 18:45 and 19:00 in sequence.

[0052] Combination Figure 3 As shown, the embodiment of the present disclosure also provides another anti-interference method for a display chip, including:

[0053] S31, when the configuration register is initialized, the main control board obtains the configuration status of the configuration register.

[0054] S32, when the configuration state indicates that the configuration register updates data, the main control board sends a control instruction for executing a configuration register refresh operation to the display chip.

[0055] S33, when the configuration state indicates that the configuration register has not updated data, the main control board obtains the configuration duration of the configuration register.

[0056] S34, the main control board controls the display chip to execute a refresh operation of the configuration register according to the configuration duration of the configuration register.

[0057] By adopting the anti-interference method for display chip provided by the embodiment of the present disclosure, when the configuration register of the display chip configuration is determined to be initialized using the main control board, the configuration status of the configuration register is obtained. When the configuration status indicates that the configuration register updates the data, it is determined that the display data of the configuration register is modified due to external interference. At this time, it is necessary to perform a refresh operation of the configuration register to avoid abnormalities of the display chip under external interference. When the configuration status indicates that the configuration register has not updated the data, the main control board determines that the configuration register is not subject to external interference. At this time, the main control board obtains the configuration duration of the configuration register, and controls the display chip to perform the refresh operation of the configuration register according to the configuration duration. In this way, the embodiment of the present disclosure uses the main control board to perform the refresh operation of the configuration register according to the configuration duration, which can not only reduce the occupation of hardware resources and improve the flexibility of the refresh operation of the display chip configuration register, but also improve the anti-interference ability of the display chip through software.

[0058] Optionally, the main control board controls the display chip to perform a refresh operation of the configuration register according to the configuration duration of the configuration register, including:

[0059] When the configuration duration meets the configuration refresh condition, the main control board sends a control instruction to the display chip.

[0060] In this way, when the configuration duration meets the configuration refresh condition, the embodiment of the present disclosure sends a control instruction to the display chip to control the configuration register to implement the refresh operation. In this way, the anti-interference ability of the display chip can be improved.

[0061] Optionally, the main control board determines whether the configuration duration meets the configuration refresh condition in the following manner:

[0062] The configured duration is greater than or equal to the refresh duration threshold.

[0063] In this way, the embodiment of the present disclosure can periodically send control instructions to the display chip to control the configuration register to implement a refresh operation, which is beneficial to improving the anti-interference capability of the display chip.

[0064] It should be noted that the refresh time threshold can be set according to needs.

[0065] Combination Figure 4 As shown, the embodiment of the present disclosure also provides another anti-interference method for a display chip, including:

[0066] S41, when the main control board is powered on and running, the main control board reads initial display data.

[0067] S42, the main control board sends an initialization instruction for executing a configuration register initialization operation to the display chip, where the initialization operation carries initial display data.

[0068] S43, when the configuration register is initialized, the main control board obtains the configuration status of the configuration register.

[0069] S44, when the configuration state indicates that the configuration register updates data, the main control board sends a control instruction for executing a configuration register refresh operation to the display chip.

[0070] By using the anti-interference method for a display chip provided by an embodiment of the present disclosure, when the main control board is used to determine that the chip is powered on, the initial display data is read. Then, the configuration register is initialized using the initial display data. In this way, the initialization of the configuration register of the display chip is realized by software. When the configuration register of the display chip configuration is determined to be initialized using the main control board, the embodiment of the present disclosure obtains the configuration state of the configuration register. When the configuration state indicates that the configuration register updates the data, it is determined that the configuration register has been modified due to external interference, causing the display data. At this time, it is necessary to perform a refresh operation of the configuration register to avoid abnormalities in the display chip under external interference. Therefore, the embodiment of the present disclosure uses the main control board to sequentially perform the initialization operation of the display chip configuration register and the anti-interference processing of the display chip, further reducing the occupation of hardware resources, thereby further improving the flexibility of the refresh operation of the display chip configuration register.

[0071] Combination Figure 5 As shown, the embodiment of the present disclosure also provides an anti-interference device 200 for a display chip, including an acquisition module 201 and an execution module 202. The acquisition module 201 is configured to obtain the configuration state of the configuration register when the configuration register is initialized. The execution module 202 is configured to send a control instruction for executing a configuration register refresh operation to the display chip when the configuration state indicates that the configuration register updates data.

[0072] The anti-interference device for display chip provided by the embodiment of the present disclosure uses the software of the main control board to monitor whether the configuration register display data has been modified, and executes the refresh operation of the configuration register when the modification is confirmed. It can reduce the occupation of hardware resources and improve the flexibility of the refresh operation of the display chip configuration register.

[0073] In practical applications, such as Figure 6 As shown, the anti-interference method for display chip specifically performs the following steps:

[0074] Step S101 : when the main control board is powered on and running, the main control board reads initial display data.

[0075] Step S102: the main control board sends an initialization instruction for executing a configuration register initialization operation to the display chip, where the initialization operation carries initial display data.

[0076] Step S103: When the configuration register is initialized, the main control board obtains the configuration status of the configuration register. Then, step S104 or step S105 is executed.

[0077] Step S104: when the configuration state indicates that the configuration register updates data, the main control board sends a control instruction for executing a configuration register refresh operation to the display chip.

[0078] Step S105 : when the configuration state indicates that the configuration register has not updated data, the main control board obtains the configuration duration of the configuration register.

[0079] Step S106: When the configuration duration is greater than or equal to the refresh duration threshold, the main control board sends a control instruction to the display chip.

[0080] Combination Figure 7 As shown, the embodiment of the present disclosure provides an anti-interference device 300 for a display chip, including a processor 400 and a memory 401. Optionally, the device may also include a communication interface 402 and a bus 403.
