Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a display control method of an LED display module according to an embodiment of the present disclosure.
The display control method specifically comprises the following steps:
s110: and acquiring an initial control signal of the LED display assembly.
In this step, the initial control signal may be a video display control signal sent by a terminal such as a mobile phone, a tablet computer, a desktop computer, or a notebook computer.
Specifically, the display control method in the scheme is that the video display control signal sent by the terminal such as the mobile phone, the tablet computer, the desktop computer or the notebook computer is sent to the corresponding LED display component, so that the LED display component can display the corresponding video information.
S120: and after filtering the initial control signal, compressing the initial control signal to obtain an initial compression control signal.
Since the EMC processing is usually performed during the transmission of the initial control signal from the terminal such as a mobile phone, a tablet computer, a desktop computer, or a notebook computer to the LED display module, signal fluctuation may occur in the initial compressed control signal. Therefore, the initial control signal needs to be subjected to a filtering process.
Specifically, in this step, the bit stream of the initial control signal may be converted into a non-return-to-zero system, so that the dc component in the initial control signal may be removed, the fluctuation of the initial control signal may be reduced, and the stability of the initial control signal may be ensured.
In particular, non-return-to-zero encoding may be used to process the initial control signal, which is received to raise the voltage at a "0" and use a low level at a "1", so that any sequence of 0's and 1's is transmitted by corresponding transitions between high and low levels. Non-return-to-zero encoding refers to the voltage remaining constant (e.g., not returning to zero) during the transmission time of a bit.
After the non-return-to-zero encoding is completed to process the initial control signal, the processed initial control signal may be subjected to reduced spectrum processing.
Specifically, the method can adopt Manchester coding, and codes binary data '0' and '1' by jumping the level of an input initial control signal, and has the advantages that the method contains abundant clock signals, the direct current component is basically zero, a receiver can easily recover a synchronous clock and synchronously demodulate data, and the method has good anti-interference performance and is more suitable for channel transmission. Through the processing signal, stable signal content is output. The output stability of the initial control signal can be improved.
After the initial control signal is subjected to the spectrum reduction processing by adopting Manchester coding, the initial control signal subjected to the spectrum reduction processing can be compressed, so that an initial compression control signal is obtained.
In this step, the initial control signal may be compressed by any one of differential coding, RLE coding, Huffman coding, LZW coding, and arithmetic coding, so as to obtain an initial compression control signal. Wherein the purpose of compressing the initial control signal is to facilitate a fast transmission of the initial control signal.
Optionally, in this step, the initial compression control signal may be detected after the initial compression control signal is obtained, so as to determine whether the video information displayed by the LED display module according to the initial compression control signal has a frame missing problem.
S130: the initial compression control signal is encoded to obtain an encoded control signal.
After step S120 is completed, step S130 may be continued to encode the initial compression control signal to obtain an encoded control signal. Specifically, since the initial control signal is compressed in step S120, in order to enable the LED display module to display the video information corresponding to the initial control signal, the initial compressed control signal needs to be encoded to obtain an encoded control signal, and the LED display module can further display the video information corresponding to the initial control signal according to the encoded control signal.
S140: and sending the coding control signal to a corresponding LED display component for decoding and outputting, so that the LED display component displays a preset video signal.
Further, in this step, the encoding control signal may be sent to the corresponding LED display module, so that the LED display module displays the preset video information.
Wherein, the coding control signal can be converted into a high-speed differential signal; the high speed differential signal is then sent to the corresponding LED display assembly.
And sending the signals to the corresponding LED display components through high-speed differential signals. The scheme has the advantages that the differential signal has strong anti-interference capability, because the coupling between the two differential wires is good, when noise interference exists outside, the differential signal is almost simultaneously coupled to the two wires, and the receiving end only concerns the difference value of the two signals, so the external common mode noise can be completely offset, the EMI can be effectively inhibited, and the same reason is that because the polarities of the two signals are opposite, the electromagnetic fields radiated by the two signals can be offset with each other, and the tighter the coupling is, the less the electromagnetic energy is released to the outside. Meanwhile, the time sequence is accurately positioned, and because the switching change of the differential signal is positioned at the intersection point of two signals, the common single-ended signal is not judged by depending on two threshold voltages, the influence of the process and the temperature is small, the error on the time sequence can be reduced, and the circuit is more suitable for a circuit with low-amplitude signals. And the Manchester coding and the differential signal are adopted, and the signal filtering is carried out doubly, so that the EMC can be effectively inhibited.
Therefore, in the embodiment, the initial control signal is filtered and then compressed to obtain the initial compressed control signal, so that the stability of the finally obtained coded control signal can be achieved, and the stability of the display effect of the display picture of the LED display module can be improved. Furthermore, the bit stream of the initial control signal is converted into a non-return-to-zero system, so that the direct current component in the initial control signal can be removed, the fluctuation of the initial control signal can be reduced, and the stability of the initial control signal is ensured. Furthermore, the encoding control signal is converted into the high-speed differential signal, so that the initial control signal can be subjected to double filtering, and the generation of EMC can be effectively inhibited.

Further, in this embodiment, a data encoding module 240 is further connected between the signal sampling compression module 220 and the parallel-serial conversion module 230. That is, the signal sampling compression module 220 compresses the filtered initial control signal, and the obtained initial compression control signal may be transmitted to the parallel-to-serial conversion module 230 through the data encoding module 240.
The data encoding module 240 is configured to detect the initial compression control signal sent by the sampling compression module 220, so as to determine whether a frame missing occurs in the video information displayed by the LED display module according to the initial compression control signal. If no missing frame problem is detected, the initial compression control signal may be transmitted to the parallel-to-serial conversion module 230 for decoding.
