Fig. 1 is a flowchart of an LED display processing method according to an embodiment of the present invention, as shown in fig. 1, the method includes the steps of:
Step S102, under the condition that the LED display is in a multi-window display mode, reading display signal types respectively corresponding to a plurality of display windows divided by the LED display.
Optionally, the multi-window display mode is used for indicating a plurality of display windows dividing the LED display, and signal display types corresponding to the plurality of display windows respectively. The signal display type may be determined based on signal source information corresponding to a display signal of a corresponding display window. Each display window can correspondingly display a display picture formed by at least one signal source. The LED display can be connected with multiple signal sources, different signal sources correspond to different signal source information (such as signal source types), the signal source information respectively connected with a plurality of display windows can be determined according to a predetermined multi-window display mode, and the display signal type corresponding to each display window in the plurality of display windows can be obtained based on the signal source information respectively connected with the plurality of display windows.
In an alternative embodiment, before reading the display signal types respectively corresponding to the plurality of display windows divided by the LED display when the LED display is in the multi-window display mode, the method further includes: outputting a plurality of groups of display signals from multiple signal sources connected to the LED display to a signal distribution card, wherein the plurality of groups of display signals are in one-to-one correspondence with the multiple signal sources; based on the multi-window display mode, multiple groups of display signals are distributed to the corresponding display box positions of the LED display through the signal distribution card to perform signal display, and initial display pictures corresponding to the multiple display windows respectively are obtained.
Optionally, the multiple signal sources may include, but are not limited to, signal sources based on digital video interface (Digital Visual Interface, DVI), high-definition multimedia interface (High Definition Multimedia Interface, HDMI), display Port (DP) access, and the signal distribution card may be one or more. Specifically, multiple signal sources accessed by the LED display can be output to one display signal distribution card or multiple signal distribution cards; and according to the currently set multi-window display mode of the LED display, distributing display signals to the corresponding display box positions of the display through the signal distribution card to perform signal display, wherein at the moment, the corresponding display picture of each display window in the LED display is the initial display picture.
It can be understood that the signal distribution card is a signal processing card or an interface card, and is used for receiving and processing display signals from different signal sources, and distributing the processed display signals to each LED display unit (i.e. display box body), so as to ensure that each LED display unit can correctly display corresponding content.
Step S104, based on the display signal types respectively corresponding to the display windows, the display parameters respectively corresponding to the display windows are read from the preset buffer memory position.
Optionally, the predetermined buffer location may be a flash of a nonvolatile storage medium, where a correspondence between a display signal type and a display parameter corresponding to a display window obtained by performing display windowing division in a plurality of different window display modes is stored in advance in the predetermined storage location. Under the condition that the display signal types corresponding to the display windows are known, the display parameters corresponding to the display windows corresponding to the multi-window display mode can be quickly read from the preset buffer position.
It should be noted that, the flash memory can store the display parameters, and even if the device is turned off or powered off, the data will not be lost, so that the storage security of the data related to the display parameters can be significantly improved. Based on the display signal types corresponding to the display windows, a microcontroller (Microcontroller Unit, MCU) can be used for reading the display parameters corresponding to the display windows from a preset cache position (such as a flash memory), and the MCU can obtain the display parameters of each signal source (such as DVI, HDMI, DP) from the flash, including brightness, color temperature, gamma curve and the like.

Based on the display parameters, the LED display can be controlled to be turned on and off, and meanwhile, the information such as the brightness, the color temperature and the tone of display can be controlled, so that the LED display has better regulation and control performance and has better display effect.
In an alternative embodiment, before reading the display parameters corresponding to the display windows from the predetermined buffer location based on the display signal types corresponding to the display windows, the method further includes: determining a plurality of window display modes corresponding to the LED display, wherein the plurality of window display modes are used for indicating a plurality of different display window dividing modes corresponding to the LED display and display signal types corresponding to each display window obtained by dividing the display window; determining display parameters of a display window corresponding to each window display mode aiming at each window display mode in a plurality of window display modes; and storing the display parameters of the display window corresponding to each window display mode to a preset buffer position.
Optionally, the multi-window display mode is a window division mode for dividing the LED display into a plurality of display windows, where the plurality of window display modes correspond to different display window division modes, and the display window division modes are used for indicating information such as the number of divided display windows, the division direction of the display windows, and the like. FIG. 2 is a schematic diagram of an alternative display window division according to an embodiment of the present invention, and as shown in FIG. 2, the display window division may include, but is not limited to, single window, double window division, quad window division, and so on. The display window dividing method may be equal display area dividing or unequal display area dividing. Namely: the display interface of the LED display can be uniformly divided into a plurality of display windows with equal display areas, and the display interface of the LED display can be divided into a plurality of display areas with incompletely equal display areas, and the specific division mode can be set according to actual service requirements.
Optionally, for each window display mode in the multiple window display modes, under the condition that the display signal type of the display window corresponding to each window display mode is known, the display parameter of the display window corresponding to each window display mode can be determined according to the display signal type of the display window corresponding to each window display mode and combining with the actual display requirement; and storing the display parameters of the display window corresponding to each window display mode to a preset buffer position. When the subsequent multi-window display is performed based on the LED display, corresponding display parameters can be quickly obtained from the preset storage position based on the display signal type corresponding to each display window, so that the multi-window display efficiency of the LED display is improved.
And S106, writing display parameters corresponding to the display windows into module cards corresponding to the display boxes in the LED display, wherein one display window corresponds to at least one display box.
Alternatively, different display windows correspond to different display boxes (i.e., LED display units), and a module card for a display box may be understood as a circuit board or a control card for directly controlling the corresponding display box in the LED display. Each display box body is provided with a module card, and the module card is responsible for receiving the display parameters of the corresponding display window acquired from the reservation storage position and directly controlling the display brightness, color and other display parameters of each display window in the LED display corresponding to the display box body.
In an alternative embodiment, writing display parameters corresponding to a plurality of display windows in a module card of a corresponding display box in an LED display includes: reading position information of the display box bodies respectively corresponding to the display windows from a preset cache position; based on the position information of the display box body corresponding to the display windows, the display parameters corresponding to the display windows are written into the module cards of the corresponding display box bodies in the LED display.
Optionally, the predetermined buffer position may further store in advance position information of the display box corresponding to each display window, and based on the position information, display parameters corresponding to the display windows respectively may be accurately written into the module card corresponding to the display box.
Step S108, based on the display parameters written in the module card corresponding to the display box body in the LED display, updating the display pictures corresponding to the display windows in the LED display.
Optionally, each display box is provided with a module card, and is responsible for adjusting the display effect of the corresponding display box according to the received display parameters, so that the update of the display pictures corresponding to the display windows in the LED display is realized.
In an alternative embodiment, the method further comprises: when detecting that any one of the display parameters corresponding to the display windows changes, determining the changed parameter corresponding to any one of the display parameters and a target display window to which any one of the display parameters belongs; updating the changed parameters to the module card of the display box corresponding to the target display window; and updating the display picture of the target display window based on the changed parameters written in the module card of the display box body corresponding to the target display window.
Optionally, when any display parameter is detected to change, the display window to which the any display parameter belongs, namely the target display window, is positioned, and the changed parameter is updated to the module card of the display box corresponding to the target display window.
In an alternative embodiment, updating the changed parameter to the module card of the display box corresponding to the target display window includes: calculating the difference between any one display parameter and the changed parameter; and under the condition that the difference value is larger than a preset difference value threshold value, updating the changed parameters to the module card of the corresponding display box body of the target display window.
Alternatively, in some cases, the change in the display parameter may be a slight change, which does not affect the picture display effect of the LED display. Based on the above, when the change of the display parameters is detected, the difference value before and after the change of the parameters can be calculated, if the difference value is larger, namely larger than a preset difference value threshold value, the parameter change is larger, and synchronous updating of the display parameters and the display pictures is required for the corresponding display window; if the difference is smaller, for example, smaller than a preset difference threshold, the parameter change is smaller, that is, the parameter change does not affect the picture display effect of the LED display, and synchronous updating of the display parameter and the display picture is not needed. By the method, the display parameters and the updating frequency of the display picture can be reduced, and then the display calculation pressure of the LED display is reduced.
The execution main body of the steps S102 to S108 may be a microcontroller, and through the steps S102 to S108, the purposes of rapidly acquiring the display parameters of each display window from the predetermined buffer position, directly writing the corresponding display parameters into the module card corresponding to the box body, and adjusting and updating the LED display picture are achieved, so that the technical effects of simplifying the multi-window display operation flow of the LED display, reducing the input cost of multi-window display are achieved, and further, the technical problems of complex operation process and high input cost when the multi-window display is performed on the LED display in the related art are solved.

Specifically, the MCU acquires corresponding signal source information on the LED display and position information of the display box body according to the instruction of the multi-window display mode; determining the display signal type of the corresponding display window based on the signal source information; the corresponding display parameters can be further read from the predetermined cache position flash according to the display signal type; the obtained display parameters can be written into the module card corresponding to the box body based on the position information of the display box body.
And S4, the MCU sends a data writing instruction, after the corresponding display parameters are written in the module card of the display box corresponding to each display window, the display effect of the display box is adjusted, and further synchronous updating of the display pictures of each display window in the LED display is realized.
