[0041] In order to make the objectives, technical solutions, and advantages of the present application clearer, the following further elaborates on the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In one embodiment, as Figure 1 shown, Figure 1 It is a schematic diagram of the overall structure of a display system in an embodiment; the display system includes a control end, a video source component, and a driving circuit component; the control end is communicatively connected to the video source component and the driving circuit component respectively.

[0043] Among them, the video source component may include, but is not limited to, a video source and a sending card. Among them, the video source is used to provide the original video data to be displayed. The sending card is used to perform data processing such as format conversion and encoding on the original video data sent by the video source, and transmit the processed video data to the control end through the corresponding communication interface.

[0044] Among them, the control end may include, but is not limited to, a receiving card and a control unit. Among them, the control unit can have various forms. For example, it may include, but is not limited to, an independent controller, a controller structure, or a control module, and no specific limitation is made here. The receiving card is used to receive the video data sent by the sending card of the video source component and perform corresponding data processing such as decoding.

[0045] Among them, the driving circuit component includes a plurality of driving circuits. It can be understood that each driving circuit is used to connect to at least one LED to ensure accurate control of each LED for corresponding display. In some embodiments, the plurality of driving circuits are distributed in an array.

[0046] In one embodiment, as Figure 2 shown, Figure 2 is a schematic flowchart of a display control method in one embodiment. The display control method is applied to the control end of the display system and includes the following steps:

[0047] Step S201, receive the vertical synchronization signal and the display parameters corresponding to different vertical frequencies sent by the video source component in the display system.

[0048] Among them, the vertical synchronization signal is used to mark the start time of each field. The vertical synchronization signal includes a plurality of start edge signals. The start edge signal is used to trigger the display of a new field.

[0049] Optionally, the vertical synchronization signal may be, but is not limited to, composed of a series of electrical signal pulses. If the vertical synchronization signal is composed of a series of electrical signal pulses, the start edge signal in the vertical synchronization signal refers to the rising edge or falling edge of each pulse in the vertical synchronization signal.

[0050] Among them, the vertical frequency refers to the vertical refresh rate, that is, the number of fields displayed per second, with the unit of Hz (Hertz). For example, a vertical frequency of 50 Hz means that 50 fields are displayed per second.

[0051] It should be noted that there are certain differences in the display parameters corresponding to different vertical frequencies. Therefore, it is necessary to set the corresponding display parameters for each vertical frequency.

[0052] Among them, the display parameters are used to perform corresponding configurations on the control end to adapt to different vertical frequency requirements. The display parameters may include, but are not limited to, scanning parameters, clock parameters, etc., and need to be set according to actual display requirements, and no specific limitation is made here.

[0053] It should be noted that the vertical synchronization signal is generated by the video source component according to a preset vertical frequency for transmission to the control terminal, and the corresponding target vertical frequency parameter is deduced inversely through the control terminal.

[0054] Step S202: Determine the target vertical frequency parameter according to the time interval between two consecutive start edge signals in the vertical synchronization signal.

[0055] Among them, the start edge signal can be a start rising edge signal or a start falling edge signal. The time interval between two consecutive start edge signals in the vertical synchronization signal is used to represent the duration of one field.

[0056] It should be noted that in practical applications, one type of edge needs to be selected for detection to maintain consistency and avoid confusion. For example, if each pulse rising edge signal in the vertical synchronization signal is selected as the start edge signal, then whenever a rising edge signal is detected, the control terminal can determine that a new field is about to start according to the rising edge signal. Furthermore, by recording the time interval between two consecutive start edge signals, the time length of one display cycle of a field can be calculated.

[0057] It should be noted that the time interval between two consecutive start edge signals in the vertical synchronization signal is set by the video source component according to the preset vertical frequency. Furthermore, by identifying the time interval between two consecutive start edge signals in the vertical synchronization signal through the control terminal, the target vertical frequency parameter can be accurately deduced inversely.

[0058] In an exemplary embodiment, the determination method of the time interval between two consecutive start edge signals in the vertical synchronization signal can be, but is not limited to, based on a clock signal. For example, according to the clock signal, by counting the clock cycles between two consecutive start edge signals in the vertical synchronization signal, the time interval between two consecutive start edge signals in the vertical synchronization signal can be obtained according to the frequency of the clock signal and the number of clock cycles.

[0059] Exemplarily, based on the clock signal, record the time interval between two consecutive start edge signals in the vertical synchronization signal. Further, according to the calculation formula of "vertical frequency = 1 / time interval", determine the target vertical frequency parameter. For example, if the time interval between two consecutive start edge signals in the vertical synchronization signal is 20 ms, the target vertical frequency parameter can be calculated to be 50 Hz, that is, 50 fields are displayed per second.

[0060] Step S203: Determine the target display parameter that matches the target vertical frequency parameter from multiple groups of display parameters.

[0061] Step S204: Perform display control on the display system according to the target display parameter.

[0062] In an exemplary embodiment, since there are corresponding display parameters for each field frequency, for each field display, when the video source component sends the display parameters corresponding to different field frequencies, it can be sent in the manner as Figure 3 shown. After receiving the vertical synchronization signal, the control terminal calculates the target field frequency parameter according to the time interval between two consecutive start edge signals in the vertical synchronization signal; then, based on the target field frequency parameter, determines the display parameter that matches the target field frequency parameter from the received multiple groups of display parameters for storage, and performs corresponding display control on the display system according to the display parameter.

[0063] It can be understood that Figure 3 the field frequency flag in

[0064] is used to mark different field frequencies. In this embodiment, the control terminal receives the vertical synchronization signal and the display parameters corresponding to different field frequencies sent by the video source component in the display system; and according to the time interval between two consecutive start edge signals in the vertical synchronization signal, can accurately determine the target field frequency parameter; then, according to the target field frequency parameter, only needs to determine the target display parameter that matches the target field frequency parameter from multiple groups of display parameters for storage; and then, according to the target display parameter, performs display control on the display system. Based on this, dynamic configuration and precise control of the display system are realized, without pre-storing the display parameters corresponding to all field frequencies at the control terminal, effectively reducing the occupation of storage resources and improving the applicability and scalability of the system under limited hardware conditions.

[0065] In one embodiment, receiving the vertical synchronization signal and the display parameters corresponding to different field frequencies sent by the video source component in the display system includes the following steps:

[0066] Receiving the vertical synchronization signal sent by the video source component in the display system, and receiving the display parameters corresponding to different field frequencies sent by the video source component within a preset parameter configuration time period.

[0067] Among them, the preset parameter configuration time period is determined by the video source component according to the time point corresponding to the start edge signal in the current field or the next field vertical synchronization signal, and the transmission status of the next field display data.

[0068] Among them, the time point corresponding to the start edge signal in the current field vertical synchronization signal is used to represent the start time of the current field; the time point corresponding to the start edge signal in the next field vertical synchronization signal is used to represent the start time of the next field or the end time of the current field.

[0069] Among them, the transmission status of the next field display data includes the start time and the end time of the transmission of the next field display data.

[0070] It should be noted that after the start of each image display, the control terminal will send the display data corresponding to the next display to the driving circuit component. Since the time for sending the display data is relatively short compared to the time for image display, there is usually an unoccupied time gap, that is, an idle period, before or after the sending of each display data. At the same time, since the frequency of the clock signal of the display system is fixed and the length of the display data is also fixed, the transmission time of each display data is usually constant.

[0071] Based on the above two characteristics, the video source component can not only accurately judge the transmission status of the next display data, but also accurately determine the preset parameter configuration time period according to the time point corresponding to the start edge signal in the current field or the next field synchronization signal, and the transmission status of the next display data, and reasonably arrange the sending timing of the display parameters accordingly.

[0072] In this embodiment, the preset parameter configuration time period is fully utilized to send the display parameters corresponding to different frame rates to the control terminal without affecting the normal transmission of the display data. In this way, it is not necessary to additionally occupy the communication bandwidth resources between the video source component and the control terminal, nor is it necessary to configure a dedicated storage space for storing the display parameters for the control terminal, realizing the efficient utilization of bandwidth and storage resources in the process of transmitting the display parameters.

[0073] In one embodiment, the display control of the display system is performed according to the target display parameters, including the following steps:

[0074] Step 1, configure the display parameters according to the target display parameters and generate a target drive control signal that matches the target display parameters.

[0075] Among them, the target drive control signal is used to precisely control the working states of the driving circuits in the driving circuit component. The target drive control signal may, but is not limited to, include information such as brightness level, color intensity, scanning order, and time interval.

[0076] Step 2, transmit the target drive control signal to the driving circuit component of the display system.

[0077] Step 3, perform display control on the driving circuit component according to the target drive control signal.

[0078] Exemplarily, for each display, the control terminal updates its own relevant parameters (such as updating the values of relevant registers) according to the target display parameters, and generates a corresponding target drive control signal according to the target display parameters to be transmitted to the driving circuit component, and performs display control on the driving circuit component according to the target drive control signal.

[0079] In this embodiment, by dynamically configuring according to the received target display parameters and generating a target drive control signal that matches them, precise control of the working states of the drive circuits in the drive circuit assembly is achieved; it can adapt to the requirements of different field frequencies and image contents, ensuring that the display system can perform corresponding displays stably and accurately.

[0080] In one embodiment, the display control method is applied to the video source component of the display system, and includes:

[0081] Sending a vertical synchronization signal to the control end in the display system, and sending the display parameters corresponding to different field frequencies to the control end within a preset parameter configuration time period, so that the control end determines the target field frequency parameter according to the time interval between two consecutive start edge signals in the vertical synchronization signal; determining the target display parameter that matches the target field frequency parameter from multiple groups of display parameters according to the target field frequency parameter; and performing display control on the display system according to the target display parameter.

[0082] Among them, the vertical synchronization signal is used to mark the start time of each field; it should be noted that the time interval between two consecutive start edge signals in the vertical synchronization signal is set by the video source component according to the preset field frequency, and then by the control end identifying the time interval between two consecutive start edge signals in the vertical synchronization signal, the control end can deduce the target field frequency parameter.

[0083] Exemplarily, for each field display, the video source component sends a vertical synchronization signal to the control end, and sends the display parameters corresponding to different field frequencies to the control end within a preset parameter configuration time period; the control end receives the vertical synchronization signal and the display parameters corresponding to different field frequencies within the preset parameter configuration time period, determines the target field frequency parameter according to the time interval between two consecutive start edge signals in the received vertical synchronization signal; and then determines the target display parameter that matches the target field frequency parameter from the multiple groups of display parameters sent by the video source component for storage; and performs display control on the display system according to the target display parameter.

[0084] In this embodiment, dynamic configuration and precise control of the display system are achieved, without the need to pre-store the display parameters corresponding to all field frequencies at the control end, effectively reducing the occupation of storage resources and improving the applicability and scalability of the system under limited hardware conditions.

[0085] In one embodiment, as Figure 4 shown, Figure 4 is a flowchart of a method for determining a preset parameter configuration time period in one embodiment; the display control method further includes the following steps:

[0086] Step S401: Obtain the time point corresponding to the starting edge signal in the current field or the next field's vertical synchronization signal, and the transmission status of the next field's display data.

[0087] It should be noted that since the vertical synchronization signal is set by the video source component according to a preset field frequency, the video source component can accurately determine the time point corresponding to the starting edge signal in the current field's vertical synchronization signal, or the time point corresponding to the starting edge signal in the next field's vertical synchronization signal. It can be understood that the current field and the next field are two consecutive fields.

[0088] Since the frequency of the clock signal of the display system is fixed and the length of the display data is also fixed, the transmission time of the display data for each field is usually constant. Based on this, the video source component can accurately determine the transmission status of the next field's display data, that is, the start time and the end time of the transmission of the next field's display data.

[0089] Step S402: Determine the preset parameter configuration time period according to the time point corresponding to the starting edge signal in the current field or the next field's vertical synchronization signal, and the transmission status of the next field's display data.

[0090] It should be noted that after the start of each image display, the control end will send the display data corresponding to the next field to the driving circuit component, and the time for sending the display data is relatively short compared to the time for image display. Therefore, there is usually an unoccupied time gap, that is, an idle period, before or after the transmission of the display data for each field. Based on the idle period of each field, determining the preset parameter configuration time period can effectively improve the utilization rate of bandwidth and storage resources during the display parameter transmission process.

[0091] It can be understood that based on the preset parameter configuration time period, the display system can regularly enter the parameter configuration stage to implement the configuration of display parameters, realizing the dynamic configuration of display parameters.

[0092] Optionally, in an exemplary embodiment, determining the preset parameter configuration time period according to the time point corresponding to the starting edge signal in the current field or the next field's vertical synchronization signal, and the transmission status of the next field's display data includes the following steps:

[0093] Step 1: Determine the start time of the current field according to the time point corresponding to the starting edge signal in the current field's vertical synchronization signal.

[0094] Step 2: Determine the first time period according to the start time of the current field and the start time of the transmission of the next field's display data.

[0095] Step 3: Determine the first time period as the preset parameter configuration time period.

[0096] Among them, the start time of the current field is earlier than the start time of the data transmission for the next field display.

[0097] Specifically, for each field display, through the video source component, according to the time point corresponding to the start edge signal in the current field vertical synchronization signal, the start time of the current field is determined; since the start time of the current field is earlier than the start time of the data transmission for the next field display, therefore, the start time of the current field is used as the lower time limit, and the start time of the data transmission for the next field display is used as the upper time limit to determine the first time period, and then the first time period is determined as the preset parameter configuration time period, and the preset parameter configuration time period is (the start time of the current field, the start time of the data transmission for the next field display).

[0098] In another exemplary embodiment, according to the time point corresponding to the start edge signal in the current field or the next field vertical synchronization signal, and the data transmission state of the next field display, to determine the preset parameter configuration time period, the following steps are included:

[0099] Step 1, according to the time point corresponding to the start edge signal in the next field vertical synchronization signal, determine the end time of the current field.

[0100] Step 2, according to the end time of the data transmission for the next field display and the end time of the current field, determine the second time period.

[0101] Step 3, determine the second time period as the preset parameter configuration time period.

[0102] Among them, the end time of the current field is later than the end time of the data transmission for the next field display.

[0103] Specifically, for each field display, through the video source component, according to the time point corresponding to the start edge signal in the next field vertical synchronization signal, determine the end time of the current field; since the end time of the current field is later than the end time of the data transmission for the next field display, therefore, the end time of the data transmission for the next field display is used as the lower time limit, and the end time of the current field is used as the upper time limit to determine the second time period, and then the second time period is determined as the preset parameter configuration time period, and the preset parameter configuration time period is (the end time of the data transmission for the next field display, the end time of the current field).

[0104] In this embodiment, by making full use of the preset parameter configuration time period, without affecting the normal data transmission of the display, the display parameters corresponding to different field frequencies are sent to the control end. In this way, there is no need to additionally occupy the communication bandwidth resources between the video source component and the control end, nor is it necessary to configure a dedicated storage space for storing display parameters for the control end, realizing the efficient utilization of bandwidth and storage resources in the process of transmitting display parameters.

[0105] In one embodiment, refer to Figure 1, A display system, including a control terminal, a video source component, and a driving circuit component; the control terminal is communicatively connected to the video source component and the driving circuit component respectively;

[0106] The control terminal is used to execute the display control method described in any one of the above embodiments;

[0109] Among them, the driving circuit component includes a plurality of driving circuits; it can be understood that each driving circuit is used to connect to at least one LED to ensure accurate control of each LED for corresponding display.

[0110] In this embodiment, the display system can perform dynamic configuration of display parameters, without pre-storing all display parameters corresponding to all field frequencies at the control terminal, effectively reducing the occupation of storage resources and improving the applicability and scalability of the system under limited hardware conditions.
