[0002] As the size of the splicing controller becomes larger and larger, the number of spliced ​​displays increases. Since the initialization time of the DA (Digital to Analog) chips connected to each display is inconsistent, the output of each display is inconsistent after it is turned on.

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In view of the problem of inconsistent output of multiple displays in the prior art, an embodiment of the present invention provides a method for synchronous display of multiple displays. Figure 2 FIG. 1 is one of the flow charts of the multi-display synchronous display method provided by an embodiment of the present invention. Figure 2 As shown, the method includes:

[0045] Step 210: Obtain EDIDs corresponding to at least two target displays.

[0046] Optionally, the EDID (Extended Display Identification Data) is a standard for display identification data developed by VESA (Video Electronics Standards Association) when developing the DDC (Digital Display Channel) display data channel communication protocol. The EDID is stored in the DDC memory in the display. When the splicing controller or device host is connected to the display, the EDID stored in the DDC memory of the display is read through the DDC channel. In addition, the EDID includes product parameters and performance parameters of the target display, wherein product parameters include but are not limited to manufacturer information, production year and EDID structure version number, etc., and performance parameters include but are not limited to supported image size, color setting parameters, frequency range limitations, supported resolution, data checksum bytes, etc.

[0047] It should be noted that the above-mentioned splicing controller, that is, the splicing controller, is a device that divides a complete image signal into N blocks and then distributes them to N target displays, thereby improving the display effect by splicing a super large screen image display screen through multiple displays.

[0048] Optionally, the video interface of the target display includes but is not limited to DVI (Digital Visual Interface), VGA (Video Graphics Array) interface, HDMI (High Definition Multimedia Interface) and DP (Display Port), etc. Different video interfaces have different characteristics and bandwidths, resulting in different EDIDs for different video interfaces.

[0049] Step 220: Based on each of the EDIDs, determine a first target resolution of a target display corresponding to each of the EDIDs, where the first target resolution is a resolution not supported by the target display.

[0050] Specifically, by performing field parsing on each EDID, the supported resolution in each EDID can be obtained, and based on the supported resolution, the unsupported resolution in each EDID, that is, the first target resolution that is not supported by each target display, can be further determined.

[0051] Step 230: Send the first target resolution corresponding to each target display to control each target display to display the first target resolution corresponding to each target display before all display parameter sets are sent.

[0052] Specifically, each target display is sent its corresponding first target resolution to ensure that before all display parameter sets are sent, each target display can be controlled to be in a no-signal state through each first target resolution, so that each target display outputs a default color parameter of the target display in the no-signal state, so that each target display outputs consistent color in the no-signal state. After each target display subsequently receives an image signal synchronously, it can synchronously output the image signal from the no-signal state, so that each target display is displayed synchronously in the input state, thereby achieving synchronous display of the entire display process of each target display, thereby improving the visual display effect and user experience.

[0053] Furthermore, before obtaining the EDIDs corresponding to the at least two target displays, the method further includes:

[0054] Acquire at least two displays and cable connection states corresponding to the at least two displays;

[0055] A display whose cable connection state is a cable inserted state is determined as the target display.

[0056] Specifically, before executing step 210, it is necessary to first detect the cable connection status corresponding to each display. If the cable connection status corresponding to the display is a cable plugged in status, it indicates that the display is one of the video display units constituting the above-mentioned ultra-large screen image display screen, and the display is determined as the target display. For the target display, the above steps 210 to 230 are executed to implement the multi-display synchronous display method provided by the embodiment of the present invention. If the cable connection status corresponding to the display is a cable unplugged status, it indicates that the display is not in use, and there is no need to obtain the EDID of the display and detect the cable plugged in status of other displays.

[0057] Further, the determining, based on each of the EDIDs, a first target resolution of a target display corresponding to each of the EDIDs includes:

[0058] For each of the EDIDs, traverse the preset resolutions in the preset resolution set, match the currently traversed preset resolution with the EDID, until a preset resolution that does not match the EDID is determined, and determine the preset resolution that does not match the EDID as the first target resolution of the target display corresponding to each of the EDIDs.

[0059] Specifically, after obtaining the EDID, a preset resolution set is further obtained, which stores at least two preset resolutions that are not supported by most displays. After field parsing of the EDID to obtain the resolution supported by the target display, the preset resolutions in the preset resolution set can be traversed, and the currently traversed preset resolution can be matched with the resolution supported in the EDID, and the first preset resolution in the preset resolution set that does not match the EDID is determined as the first target resolution of the target display corresponding to the EDID.

[0060] Furthermore, the controlling each of the target displays to display the first target resolution corresponding to the respective ones includes:

[0061] For each of the first target resolutions, determining a first blanking parameter corresponding to the first target resolution;

[0062] Based on each of the first blanking parameters, configuring the FPGA chip 550 of the target display corresponding to each of the first target resolutions;

[0063] A first synchronization signal is sent to each of the FPGA chips 550 simultaneously, wherein the first synchronization signal is used to trigger the first blanking parameters corresponding to each of the target displays to take effect, and after all the first blanking parameters take effect, each of the target displays is controlled to display its corresponding first target resolution.

[0064] Specifically, Figure 3 FIG. 2 is a second flow chart of a multi-display synchronous display method provided by an embodiment of the present invention. Figure 3As shown, after the splicing controller is turned on, the DA (Digital to Analog, digital analog conversion) chip 560 is de-reset, and the EDID corresponding to each target display is obtained, and the EDID can be further parsed to obtain the first target resolution corresponding to each target display. After determining the first target resolution corresponding to each target display, the first blanking parameter corresponding to each first target resolution can be further obtained, and the first blanking parameter is an abnormal parameter related to the scanning process of the image. After the FPGA chip 550 connected by the DA chip 560 is initialized by the target display, the first blanking parameter corresponding to the first target resolution not supported by the target display is configured based on the output clock register of the FPGA chip 550, and the first synchronization signal is sent to each FPGA chip 550 at the same time. Through the first synchronization signal, the first blanking parameter configured is triggered to take effect, thereby ensuring that the corresponding target display displays the first target resolution before outputting the image signal, that is, ensuring that each target display is in a no-signal state before outputting the image signal, ensuring that before all display parameter sets are not fully issued, each target display outputs the default color parameter, so as to ensure that each target display displays the same color in a no-signal state, and improve the display effect of each display in the startup phase of the splicing controller. When the image signal is output, the FPGA chip 550 corresponding to at least two target displays is controlled to output the display signal synchronously, so that each target display can synchronously output the image signal from a no-signal state, further improving the display effect of each target display in the output stage of the splicing controller, thereby realizing synchronous display of each target display.

[0065] Further, such as Figure 3 As shown, the method also includes:

[0066] Determine a second target resolution corresponding to each of the target displays, where the second target resolution is a resolution supported by the target display;

[0067] Determine a second blanking parameter corresponding to each of the second target resolutions;

[0068] Sending a display parameter set to each of the FPGA chips 550;

[0069] After all display parameter sets are sent, configuring the FPGA chip 550 corresponding to each of the target displays based on each of the second blanking parameters;

[0070] A second synchronization signal is sent to each of the FPGA chips 550 simultaneously, and the second synchronization signal is used to trigger the second blanking parameters corresponding to each of the target displays to take effect, and after all the second blanking parameters take effect, control each of the target displays to display its corresponding second target resolution.

[0071] Specifically, according to the EDID corresponding to each target display, the supported resolution can be determined, and any supported resolution can be determined as the second target resolution, and the second blanking parameter corresponding to the second target resolution can be obtained by parsing from the EDID, and the second blanking parameter is a normal parameter related to the image scanning process. After that, a display parameter set is sent to each FPGA chip 550, and after all display parameter sets are sent, the register of the FPGA chip 550 is configured according to the second blanking parameter and the output clock to ensure that each target display is in the input state, but the second blanking parameter is an invalid parameter at this time. After the second synchronization signal is synchronously sent to all FPGA chips 550, the second blanking parameter can be triggered to take effect synchronously, so as to control each target display to display the corresponding second target resolution, thereby making each target display synchronously display the image signal to improve the visual display effect.

[0072] Further, sending the display parameter set to each of the FPGA chips 550 includes:

[0073] Initialize the DA chip 560 corresponding to each of the FPGA chips 550;

[0074] Creating a display parameter set corresponding to each of the target displays;

[0075] Each of the display parameter sets is sent to the FPGA chip 550 corresponding to each of the target displays.

[0076] Specifically, before configuring the FPGA chip 550 of the target display according to the second blanking parameter, it is necessary to initialize the DA chip 560 corresponding to the FPGA chip 550. After the initialization of each DA chip 560 is completed, a display parameter set corresponding to each target display is created. The display parameter set includes but is not limited to the data flow direction, cropping parameters and coordinate position corresponding to the image signal. The coordinate position can be understood as the display position of the image signal in the target display, and the coordinate position can be represented by the number of rows and columns in the target display. After creating the display parameter set, the display parameter set corresponding to each target display can be sent serially to the FPGA chip 550 corresponding to each target display. After all display parameter sets are sent to the corresponding FPGA chip 550, each FPGA chip 550 can be further configured according to the second blanking parameter to ensure that each target display can directly and synchronously output the image signal from a no-signal state, thereby improving the visual display effect and user experience.

[0077] The multi-display synchronous display method provided by the embodiment of the present invention obtains the EDID corresponding to each target display and parses the EDID to obtain the first target resolution corresponding to each target display. Through the first target resolution not supported by the target display, each target display is controlled to display the first target resolution corresponding to each target display before all display parameter sets are sent. That is, each target display is in a no-signal state during the startup phase, thereby ensuring that the output color of each target display remains consistent during the startup phase, until each target display synchronously receives an image signal and synchronously outputs the image signal, ensuring that each target display displays synchronously during the startup phase and the output phase, thereby improving the visual display effect of each target display and improving the user experience.
