[0057] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiment of the dimming component described herein is used to explain this application and is not intended to limit this application.

The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0059] It is to be understood that the terms “first”, “second”, and etc. can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first resistor can be called a second resistor without departing from the scope of the present application, and similarly, a second resistor can be called a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0060] It is to be understood that “connection” in the following embodiments, if the circuits, modules, units, etc. connected to each other have transmission of electrical signals or data, should be understood as “electrically connected”, “communicatively connected” and the like.

[0061] It is to be understood that “at least one” means one or more, and “multiple” means two or more. “At least part of an element” means part or all of the element.

[0062] As used herein, the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. It is also to be understood that the term “comprising” or “including” or “having” or the like, means the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0063] For example, for a display and control computer, a single-chip microcomputer is generally used to control the generation of a PWM (Pulse Width Modulation) waveform to a dimming circuit, so that the dimming circuit performs dimming control of the display and control computer based on the PWM waveform.

[0064] However, the current device dimming method requires an additional single-chip microcomputer to control the dimming of the device, which is difficult to implement and increases the cost for devices with high space limitation requirements. In particular, for display and control computer devices, if the operating system is used to control dimming, an additional communication interface between the CPU (Central Processing Unit) and the single-chip microcomputer is required, i.e., the device needs to interact with the single-chip microcomputer through this communication interface to achieve dimming control, which is relatively inefficient.

[0065] To this end, the application provides a device dimming system, which comprises a processor, a programmable logic chip and a dimming component arranged in a device. The processor can generate a dimming control protocol waveform matched with a dimming instruction according to the dimming instruction, and then the generated dimming control protocol waveform can be efficiently sent to the programmable logic chip of the device without setting an additional single-chip device. The programmable logic chip can make the processor more efficiently run without occupying too many resources of the processor, and can also improve the efficiency of the programmable logic chip in converting the dimming control protocol waveform into a target pulse width modulation waveform, shorten the time for the dimming component to obtain the target pulse width modulation waveform, and make the dimming component efficiently dim the device.

[0066] In one exemplary embodiment, as shown in Figure 1 a device dimming system 103 is provided, which is arranged in a device 104, wherein:

[0067] a processor 105 is configured to obtain a dimming instruction of the device 104, process the dimming instruction, obtain a dimming control protocol waveform matched with the dimming instruction, and send the dimming control protocol waveform to a programmable logic chip 106;

[0068] the programmable logic chip 106 is configured to convert the detected dimming control protocol waveform into a target pulse width modulation waveform, and feed back the target pulse width modulation waveform to a dimming component 107;

[0069] the dimming component 107 is configured to dim the device 104 according to the target pulse width modulation waveform.

[0070] In the application, the device 104 is generally a computer, an electronic device or an intelligent system, which can be a display and control computer, and can also be an embedded computer, wherein the display and control computer is a special computer integrating display function and control function.

[0071] The processor 105 is arranged in the device 104, is a core hardware component responsible for executing calculation, processing data and controlling instruction flow in the device 104, and is an “operation center” for realizing information processing and logical decision. The core function of the processor 105 is to process and operate input data according to a preset program (instruction set), and output results, so as to coordinate the cooperative work of other hardware (such as a memory and an input and output device 104) in the device 104. Generally, the processor 105 can be a CPU of the device 104.

[0072] The programmable logic chip 106 is a chip that is self-provided by the device 104, and is a type of semiconductor chip that can flexibly define the internal logic function through programming (rather than hardware modification). The core feature is that the user can configure the internal logic gate, flip-flop, interconnection line, and other hardware resources according to the needs to realize the self-defined digital logic function (such as logic operation, timing control, signal conversion, etc.), without the need to redesign the physical structure of the chip. Generally, the programmable logic chip 106 can be a CPLD (Complex Programmable Logic Device), which is an integrated circuit chip that can flexibly configure the internal logic structure through programming. Through the internal programmable logic unit, interconnection resource, and I / O interface, the user can self-define the digital logic function (such as logic operation, timing control, signal conversion, etc.) according to the needs, without the need to redesign the hardware of the chip. The programmable logic chip 106 can also be other PLD (Programmable Logic Device), but compared with other PLDs, the CPLD has higher logic scale and structural complexity, larger programmable range, and more widely applicable scenarios. Therefore, in order to improve the efficiency of the dimming control of the device 104, the CPLD is generally used as the programmable logic chip 106 in the present application.

[0073] The dimming component 107 refers to a general term for a type of electronic element, module, or system for adjusting the luminous intensity. The core function is to realize continuous or stepwise adjustment of the luminous intensity of the light source by changing the current, voltage, or luminous flux, etc. parameters, to adapt to the lighting needs of different scenes. Generally, the dimming component 107 can be a dimming circuit, and can also be a modular unit, integrated system, or dedicated device containing hardware, software, or mechanical structure. The core function of the component that realizes the luminous intensity adjustment can be referred to as the dimming component 107.

[0074] Specifically, the processor 105 and the programmable logic chip 106 are both arranged inside the device 104. The user sends the dimming instruction of the device 104 to the processor 105. The processor 105 receives the dimming instruction of the device 104, processes the dimming instruction, and sends the processing result to the programmable logic chip 106. The programmable logic chip 106 further processes the processing result output by the processor 105 to convert the processing result output by the processor 105 from the data of the original protocol to the data of the protocol that can be adapted to the dimming component 107, so that the dimming component 107 adjusts the device 104 according to the target pulse width modulation waveform.

[0075] In more detail, the processor 105 processes the dimming instruction to obtain a dimming control protocol waveform matched with the dimming instruction, wherein the dimming control protocol waveform includes a specific number of low level information and high level information, and sends the dimming control protocol waveform matched with the dimming instruction to the programmable logic chip 106. The programmable logic chip 106 internally implements various logical judgments and processing of the dimming control protocol waveform through programmable logic to output a PWM waveform corresponding to the duty cycle of the dimming control protocol waveform, that is, a target pulse width modulation waveform, and feeds back the target pulse width modulation waveform to the dimming component 107, so that the dimming component 107 can effectively dim the device 104 according to the target pulse width modulation waveform.

[0076] In one embodiment, in the process of converting the dimming control protocol waveform into data of a protocol that can be adapted to the dimming component 107 by the programmable logic chip 106, the protocol conversion can be achieved through the following steps:

[0077] 1. Receive source protocol signal: capture the electrical signal of the original protocol, that is, the dimming control protocol waveform, through the input pin of the programmable logic chip 106.

[0078] 2. Analyze protocol format: identify the data frame structure of the source protocol (such as start bit, data bit, and check bit) with the internal logic circuit of the programmable logic chip 106.

[0079] 3. Data conversion and recombination: repackage the parsed data according to the format of the target protocol (such as adding a new frame header and adjusting the bit width).

[0080] 4. Output target protocol signal: send the converted data, that is, the target pulse width modulation waveform, to the dimming component 107 through the output pin of the programmable logic chip 106 according to the timing of the target protocol (such as clock frequency and level standard).

[0081] In one embodiment, the process of the user sending the dimming instruction of the device 104 to the processor 105: the user sends the dimming instruction of the device 104 to the system layer of the device 104, that is, the operating system, through physical buttons connected to the processor 105 or software parameter settings of touch software in communication with the processor 105, and the operating system further sends the dimming instruction to the processor 105.

[0082] The device dimming system 103, the method, the device, the computer device, the computer readable storage medium and the computer program product, the system includes a processor 105, a programmable logic chip 106 and a dimming component 107 arranged inside the device 104, the processor 105 can generate a dimming control protocol waveform matched with the dimming instruction according to the dimming instruction, and then the generated dimming control protocol waveform can be sent to the programmable editing chip of the device 104 without setting an additional single-chip device, and the programmable logic chip 106 can be used without occupying too many resources of the processor 105, so that the processor 105 can run more efficiently, and the efficiency of the programmable logic chip 106 in converting the dimming control protocol waveform into a target pulse width modulation waveform can be improved, the time for the dimming component 107 to obtain the target pulse width modulation waveform is shortened, and the dimming component 107 can efficiently dim the device 104.

[0083] In an exemplary embodiment, the programmable logic chip 106 is further configured to:

[0084] obtain a target low-level time length of the dimming control protocol waveform and a preset period time length, detect duty cycle information according to the target low-level time length and the preset period time length, and generate a target pulse width modulation waveform corresponding to the dimming control protocol waveform according to the duty cycle information.

[0085] Specifically, after the processor 105 receives the dimming instruction, the processor 105 analyzes the dimming instruction and sends a dimming control protocol waveform matched with the dimming instruction to the programmable logic chip 106, wherein the dimming control protocol waveform includes a specific number of low-level information and high-level information.

[0086] Therefore, the programmable logic chip 106 can obtain a low-level time length of the dimming control protocol waveform according to the specific number of low-level information, and obtain a total preset period time length of the dimming control protocol waveform according to the specific number of low-level information and high-level information.

[0087] The low-level time length in the total preset period time length is taken as a target low-level time length, and duty cycle information of a pulse width modulation waveform to be generated is determined according to a ratio of the target low-level time length to the preset period time length, so that the target pulse width modulation waveform corresponding to the dimming control protocol waveform can be generated through the duty cycle information.

[0088] For example, the total preset period length is 500 ms, and if the low level length in the preset period length is 100 ms, the duty cycle information of the pulse width modulation waveform to be generated is 100 ms / 500 ms X 100% = 20%; for another example, if the low level length in the preset period length is 250 ms, the duty cycle information of the pulse width modulation waveform to be generated is 250 ms / 500 ms X 100% = 50%.

[0089] In the above embodiment, by obtaining the target low level length of the dimming control protocol waveform and the preset period length, the duty cycle information of the pulse width modulation waveform to be generated can be detected, and the target low level length of the dimming control protocol waveform is determined by the dimming instruction, so that the target pulse width modulation waveform can be generated according to the duty cycle information.

[0090] In one exemplary embodiment, the processor 105 is further configured to:

[0091] According to the dimming instruction, a first number of low level information written to the corresponding programmable logic chip 106 is determined; according to the first number, a low level length corresponding to the first number is generated, and a dimming control protocol waveform matching the dimming instruction is generated according to the low level length.

[0092] Specifically, the processor 105 analyzes the dimming instruction to determine a first number of low level information written to the corresponding programmable logic chip 106. At this time, the processor 105 generates a low level length in the dimming control protocol waveform to be generated according to the first number. For example, a corresponding relationship between the low level length and the number of low level information can be obtained in advance, and a low level length matching the first number of low level information is generated, such as 100 ms of low level in a dimming control protocol waveform to be generated when one low level information corresponds to 1 ms of low level and the first number of low level information is 100. In addition, a preset period length of the dimming control protocol waveform to be generated can be obtained, so that the dimming control protocol waveform can be generated according to the preset period length and the low level length.

[0093] It should be noted that the dimming control protocol waveform can be pulled low first and then pulled high, or pulled high first and then pulled low. When pulled low first and then pulled high, in each period of the dimming control protocol waveform, there is a low level of a certain length first, and then a high level of a certain length.

[0094] In one embodiment, the dimming control protocol waveform is generated according to the preset period length and the low level length, including: detecting a high level length in the dimming control protocol waveform to be generated, and generating a final dimming control protocol waveform according to the low level length and the high level length.

[0095] In one embodiment, after determining the first quantity of low-level information to be written to the corresponding programmable logic chip 106, the processor 105 directly writes the first quantity of low-level information to the corresponding programmable logic chip 106, and also writes a specific quantity of high-level information to the corresponding programmable logic chip 106 according to the high-level duration, so that the corresponding programmable logic chip 106 detects the dimming control protocol waveform according to the first quantity of low-level information and the specific quantity of high-level information.

[0096] In the above embodiment, according to the dimming instruction, the first quantity of low-level information to be written to the corresponding programmable logic chip 106 is determined, which can accurately detect the low-level duration in the dimming control protocol waveform, so that an accurate dimming control protocol waveform for dimming can be generated.

[0097] In one exemplary embodiment, the processor 105 is further configured to:

[0098] obtain a mapping relationship between the preset quantity of low-level information and the adjustment brightness parameter, obtain the target adjustment brightness parameter of the device 104 from the dimming instruction, and detect the first quantity of low-level information matched with the target adjustment brightness parameter according to the mapping relationship.

[0099] Specifically, when determining the first quantity of low-level information to be written to the corresponding programmable logic chip 106 according to the dimming instruction, the processor 105 pre-obtains a mapping relationship between the preset quantity of low-level information and the adjustment brightness parameter, and analyzes the dimming instruction to obtain the target adjustment brightness parameter of the device 104.

[0100] At this time, since the processor 105 pre-obtains the mapping relationship between the preset quantity of low-level information and the adjustment brightness parameter, and the target adjustment brightness parameter of the device 104 is known, the first quantity of low-level information matched with the target adjustment brightness parameter of the device 104 can be queried from the mapping relationship according to the target adjustment brightness parameter of the device 104.

[0101] In actual application, the adjustment brightness parameter is generally represented in the form of numbers or letters. In the case where the range of the adjustment brightness parameter is 1-100, analyzing the dimming instruction to obtain the target adjustment brightness parameter of the device 104 can be any one parameter in 1-100. The smaller the adjustment brightness parameter, the more the dimming instruction can represent the reduction of brightness, or the increase of brightness, which is set by the user. Further, it can be considered that the target adjustment brightness parameter of the device 104 is carried in the dimming instruction, that is, when setting the dimming instruction, the user selects or writes the target adjustment brightness parameter of the device 104, so that the target adjustment brightness parameter of the device 104 is carried in the dimming instruction, and the dimming instruction is sent to the processor 105.

[0102] In one embodiment, the more the number of low-level information, the greater the duty cycle of the target pulse width modulation waveform, and dimming the device 104 will increase the brightness of the device 104. Therefore, before obtaining the mapping relationship between the preset number of low-level information and the adjustment brightness parameter, the correlation between the adjustment brightness parameter and the number of low-level information can also be determined in advance, that is, it is determined that the greater the adjustment brightness parameter, the more the number of low-level information, or it is determined that the greater the adjustment brightness parameter, the less the number of low-level information. When the greater the adjustment brightness parameter, the more the number of low-level information, the greater the adjustment brightness parameter means that dimming the device 104 will increase the brightness of the device 104; when the greater the adjustment brightness parameter, the less the number of low-level information, the greater the adjustment brightness parameter means that dimming the device 104 will darken the brightness of the device 104.

[0103] In the above embodiment, by obtaining the mapping relationship between the preset number of low-level information and the adjustment brightness parameter, the first number of low-level information matched with the target adjustment brightness parameter can be quickly and accurately queried, so as to improve the efficiency of generating the dimming control protocol waveform, and further improve the efficiency of dimming the device 104.

[0104] In one exemplary embodiment, the processor 105 is further configured to:

[0105] Before sending the dimming control protocol waveform to the programmable logic chip 106, the preset second number of low-level information and the preset third number of high-level information are sent to the programmable logic chip 106, so that the programmable logic chip 106 enters the detection state of the control protocol waveform.

[0106] Specifically, after the processor 105 is powered on, if the processor 105 does not receive a dimming instruction, the dimming control protocol waveform sent by the processor 105 is in a low level by default at this time, and at this time, the duty cycle of the target pulse width modulation waveform output by the programmable logic chip 106 is a default duty cycle.

[0107] When the processor 105 receives the dimming instruction, the processor 105 sends the preset second number of low-level information and the preset third number of high-level information to the programmable logic chip 106, so that the dimming control protocol waveform sent is pulled up and then pulled down, or pulled down and then pulled up, so that the programmable logic chip 106 enters the detection state of the control protocol waveform.

[0108] After the programmable logic chip 106 enters the detection state of the control protocol waveform, the processor 105 parses the dimming instruction again to obtain a first number of low-level information to be written to the corresponding programmable logic chip 106, and according to the first number of low-level information, the dimming control protocol waveform is pulled low again to generate a new dimming control protocol waveform, so that the programmable logic chip 106 converts the detected dimming control protocol waveform into a target pulse width modulation waveform.

[0109] In the above embodiment, before the dimming control protocol waveform is sent to the programmable logic chip 106, the preset second number of low-level information and the preset third number of high-level information are sent to the programmable logic chip 106, so that the programmable logic chip 106 can reliably enter the detection state of the control protocol waveform, and then the operation of converting the detected dimming control protocol waveform into a target pulse width modulation waveform can be completed.

[0110] In an exemplary embodiment, as shown in Figure 2 The device dimming system 103 further comprises:

[0111] The processor interface 108 is connected with the programmable logic chip 106 and the processor 105 respectively, and the processor interface 108 is used to send the dimming control protocol waveform generated by the processor 105 to the programmable logic chip 106.

[0112] The processor interface 108 refers to the physical connection point and corresponding communication specification of the processor 105 (such as CPU, etc.) for data transmission, signal interaction or instruction communication with external components (other chips, memories, peripherals, buses, etc.). It not only includes the physical pins, connectors at the hardware level, but also covers the communication protocols, signal timing and other rules at the software level, to ensure that the processor 105 and other structures can orderly and accurately transmit data and control signals. Generally, the processor interface 108 can be a GPIO (General Purpose Input / Output, general purpose input / output interface), which is a general-purpose pin on the processor 105 that can be flexibly configured as an input or output state through software programming, and is used to realize simple signal interaction between the chip and other structures.

[0113] Specifically, the processor interface 108 is further arranged between the programmable logic chip 106 and the processor 105, and the processor interface 108 is used to realize the interaction between the programmable logic chip 106 and the processor 105, so that the dimming control protocol waveform generated by the processor 105 is sent to the programmable logic chip 106.

[0114] In one embodiment, the programmable logic chip 106 has IO BANKs (input / output bank, which refers to a set of input / output pins sharing the same electrical characteristics (such as voltage, signal standard), which is the basic unit for the chip to interact with external circuits (such as sensors, actuators, other chips) for signal exchange) with different voltage levels. The programmable logic chip 106 can connect the BANK with the corresponding voltage level and the processor interface 108 through the IO BANK with different voltage levels, for subsequent receiving the corresponding dimming control protocol waveform generated by the processor 105.

[0115] In the above embodiment, the response speed of the programmable logic chip 106 is faster than that of the corresponding interface of the single-chip microcomputer, and therefore, by setting the processor interface 108 between the programmable logic chip 106 and the processor 105, the dimming control protocol waveform generated by the processor 105 can be efficiently sent to the programmable logic chip 106.

[0116] In one exemplary embodiment, the embodiments of the present application also provide a device dimming method, which can be applied to the application environment as shown in Figure 1 . In the application environment, the device dimming system 103 is arranged in the interior of the device 104, the device dimming system 103 is used for dimming the device 104, and the device dimming system 103 comprises the processor 105, the programmable logic chip 106 and the dimming component 107.

[0117] The user sends the dimming instruction of the device 104 to the processor 105 in the device dimming system 103 through the key of the device 104 or the touch software of the device 104. The processor 105 obtains the dimming instruction of the device 104, processes the dimming instruction, obtains the dimming control protocol waveform matched with the dimming instruction, and sends the dimming control protocol waveform to the programmable logic chip 106; the programmable logic chip 106 converts the detected dimming control protocol waveform into a target pulse width modulation waveform, and feeds back the target pulse width modulation waveform to the dimming component 107; and the dimming component 107 dimming the device 104 according to the target pulse width modulation waveform.

[0118] In one exemplary embodiment, as shown in Figure 3 , a device dimming method is provided, and the device dimming method is applied to the device dimming system in Figure 1 . In the device dimming system, the following steps are performed.

[0119] S100, obtaining a dimming instruction of a device.

[0120] Specifically, the terminal sends the dimming instruction of the device to the processor in the device dimming system.

[0121] S200, processing the dimming instruction to obtain a dimming control protocol waveform matched with the dimming instruction.

[0122] Specifically, after the processor is powered on, if the processor does not receive the dimming instruction, the dimming control protocol waveform sent by the processor is at a default low level at this time, and at this time, the duty cycle of the target pulse width modulation waveform output by the programmable logic chip is a default duty cycle.

[0123] When the processor receives the dimming instruction, the processor sends a specific number of low level information and a specific number of high level information to the programmable logic chip, so that the dimming control protocol waveform sent is pulled up and then pulled down, and the programmable logic chip enters a detection state of the control protocol waveform.

[0124] After the programmable logic chip enters the detection state of the control protocol waveform, the processor analyzes the dimming instruction to obtain a first number of low level information written to the corresponding programmable logic chip, and according to the first number of low level information, the dimming control protocol waveform is pulled down again to generate a new dimming control protocol waveform, and the new dimming control protocol waveform is sent to the programmable logic chip, so that the programmable logic chip converts the detected dimming control protocol waveform into a target pulse width modulation waveform.

[0125] The processor obtains the first number of low level information written to the corresponding programmable logic chip, including: the processor obtains a mapping relationship between a preset number of low level information and an adjustment brightness parameter; obtaining a target adjustment brightness parameter of the device from the dimming instruction, and detecting a first number of low level information matched with the target adjustment brightness parameter according to the mapping relationship.

[0126] S300, converting the dimming control protocol waveform into a target pulse width modulation waveform.

[0127] Specifically, after the programmable logic chip detects the dimming control protocol waveform, the programmable logic chip obtains a target low level time length of the dimming control protocol waveform and a preset period time length, detects duty cycle information according to the target low level time length and the preset period time length, and generates a target pulse width modulation waveform corresponding to the dimming control protocol waveform according to the duty cycle information, and feeds back the target pulse width modulation waveform to the dimming component.

[0128] S400, dimming the device according to the target pulse width modulation waveform.

[0129] Specifically, the dimming component dimming the device according to the target pulse width modulation waveform, such as making the brightness of the device darker or making the brightness of the device higher.

[0130] The device dimming method has the advantages that since the device dimming method is applied to a device dimming system, the system includes a processor, a programmable logic chip and a dimming component arranged in the device, the processor can quickly generate a dimming control protocol waveform matched with a dimming instruction according to the dimming instruction, the generated dimming control protocol waveform can be efficiently sent to a programmable editing chip of the device without arranging an additional single-chip device, the programmable logic chip can be used to make the processor more efficiently operate without occupying too many resources of the processor, the efficiency of the programmable logic chip in converting the dimming control protocol waveform into a target pulse width modulation waveform is improved, the time for the dimming component to obtain the target pulse width modulation waveform is shortened, and the dimming component can efficiently dim the device.

[0131] The process of dimming the device through the device dimming system of the display control computer will be described in detail below, and the device is taken as the display control computer as an example, wherein:

[0132] The hardware interaction schematic diagram of the technical solution is shown in Figure 4 The system layer of the processor CPU in the display control computer is an operating system, and after entering the operating system, the system can be used to send various protocol waveforms from the processor interface GPIO of the CPU to the programmable logic chip CPLD.

[0133] Specifically, if the CPU does not receive a dimming instruction after power-on, the dimming control protocol waveform sent from the CPU to the GPIO is at a default low level, and the duty cycle of the pulse width modulation waveform sent from the programmable logic chip GPIO is a default duty cycle.

[0134] If the CPU receives a dimming instruction, the dimming control protocol waveform sent from the CPU to the programmable logic chip GPIO is pulled high for 100 ms and then pulled low, so that the CPLD enters a detection state.

[0135] Then, within a preset period of 500 ms after being pulled low, the dimming control protocol waveform is pulled high again after different pull-down times according to the dimming instruction, and the latest dimming control protocol waveform is sent to the programmable logic chip CPLD, and since the CPLD has input-output groups IO BANK with different voltage levels, the BANK corresponding to the level can be connected with the GPIO of the CPU, so that the CPLD can receive the new dimming control protocol waveform, and various logic judgments and processing can be realized through the programmable logic, and a target pulse width modulation PWM waveform with a corresponding duty cycle is output to the dimming component, which can be a dimming circuit in general.

[0136] For example, the dimming control protocol waveform is pulled down for 100 ms in a preset period of 500 ms, and the CPLD can set the duty cycle of the output PWM waveform to 100 ms / 500 ms X 100% = 20% according to the 100 ms pull-down time.

[0137] Finally, the dimming component dimming the display control computer according to the target pulse width modulation waveform.

[0138] During the whole process, compared with the previous display control computer device dimming processing by the single-chip microcomputer, the device cannot be realized and the cost is increased for the device with high space limitation requirement, or the CPU parses and processes the PWM waveform continuously, which occupies a high resource of the CPU. The technical solution adopts the CPU of the display control computer to parse and process the dimming instruction, and the CPLD device of the display control computer continuously outputs the PWM with different duty cycles according to the control protocol waveform parsed by the CPU. The single-chip microcomputer device is not increased, and the CPU resource is not occupied. The application scenario with high space limitation requirement is met, the cost is reduced, and the efficiency of dimming control is provided.
