Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0043] Embodiment one

[0044] See Figure 1 The embodiment of the present application provides a display module and decoding module adaptation method, which specifically comprises the following steps:

[0045] S1: determining a row scanning period of a display module;

[0046] S2: acquiring a change level signal output by a decoding module in one row scanning period;

[0047] S3: acquiring preset decoding data according to the change level signal;

[0048] S4: setting the preset decoding data as a corresponding configuration item of the decoding module;

[0049] S5: driving the display module according to the configuration item and content data.

[0050] Specifically, in the display module of the LED display screen system, a row scanning period is used to describe the time interval of scanning all rows of the display module in a refresh period. In a row scanning period, all rows will be scanned in sequence to update the display content. The decoding module is responsible for converting the input row selection signal into a control signal for driving the corresponding row of the display module to light up. The changing level signal in the row scanning period is the level signal output by the decoding module during a row scanning period. If the level signal changes 16 times, the scanning mode of the display module driven by it is 1 / 16 scanning. The changing level signal of the decoding module can be obtained through the relevant signal waveform description in its product specification or through devices such as an oscilloscope. After obtaining these changing level signals, the preset decoding data is obtained according to the changing level signals, that is, the changing law of the changing level signal is encoded to convert the changing level signal into preset decoding data suitable for controlling the display module. Preferably, the preset decoding data includes row selection data (data corresponding to the row selection signal) for determining the current display row and latch data (data corresponding to the latch signal) for locking the data content of the current display row. In other embodiments, enable data (corresponding to the enable signal) can also be included. Then, the preset decoding data is used as the corresponding configuration item of the decoding module. The process of using the preset decoding data as the configuration item is actually storing it in the host computer. By storing the preset decoding data corresponding to various decoding modules as configuration items in the host computer, a configuration set is formed. When the decoding module needs to be replaced, there is no need to modify the code or update the firmware, but the corresponding configuration item of the decoding module to be replaced can be directly obtained from the host computer to obtain the preset decoding data. Finally, the display module is driven according to the preset decoding data and the content data (i.e., RGB data). When a new decoding module is needed, the preset decoding data corresponding to the new decoding module is obtained and added as a new configuration item to the configuration set. Subsequently, the corresponding configuration item is called from the host computer to obtain the corresponding preset decoding data when driving the display module, and the display module is driven according to the preset decoding data and the content data. By setting the decoding data of the decoding module as a flexible configuration item, the display module can be adapted to various decoding modules, improving the compatibility and expandability of the LED display screen system. At the same time, it can effectively reduce the need for firmware modification and update, and improve the reliability and stability of the system.

[0051] In one embodiment, the preset decoding data obtained according to the changing level signal includes:

[0052] obtaining first changing level signals and second changing level signals corresponding to row selection signals and latch signals of the display module in the changing level signal, respectively;

[0053] The row selection decoding data is obtained based on the first changing level signal;

[0054] The latched decoding data is obtained based on the second changing level signal;

[0055] The row selection decoding data and the latch decoding data are combined into the preset decoding data.

[0056] Specifically, the level change signal represents the level signal change output by the decoding module within one line scan cycle. In LED displays, different lines in the display module are often controlled by line selection signals, while latch signals are used to lock the display content of the currently scanned line. Therefore, it is necessary to determine the corresponding level change signals for the line selection signal and the latch signal from the level change signals, namely the first level change signal and the second level change signal, and encode them. Encoding the first level change signal involves converting its changes into line selection decoded data. Encoding the first level change signal helps determine which line is currently being scanned. Encoding the second level change signal involves converting its changes into latch decoded data. After merging these two parts of data, preset decoded data is obtained. This preset decoded data includes line selection decoded data used to indicate the currently scanned line and latch decoded data used to lock the display content.

[0057] The following sections will use two different decoding modules to illustrate how to encode preset decoded data based on changing level signals.

[0058] like Figure 2 The image shows the output waveform of a decoding module when driving a 64×16 display module (scanning mode 1 / 16). The waveforms of channels 0, 1, 2, and 3 correspond to the waveforms of the row selection signals ABCD, and the waveform of channel 5 corresponds to the waveform of the latch signal lat. The changing level signal within one row scan cycle is selected, as shown... Figure 2 As shown in region 21 enclosed by the dashed line, the changing level signals in channels 0-3 within region 21 constitute the first changing level signal, while the second changing level signal is the changing level signal in channel 5. First, the level signals in channels 0-3 are encoded, changing 16 times within one row scan cycle. Based on this change pattern, the row selection decoding data corresponding to the second changing level signal can be obtained as 0000, 0001, 0010, 0011, ..., 1111. Each time the second changing level signal changes, the corresponding second changing level signal undergoes a high-level change, and the corresponding latch decoding data is 1, 1, 1, 1, ..., 1. After encoding the waveform output by this type of decoding module, its change pattern is sequentially increasing. The signals of n channels change m times within one row scan cycle, where m = 2. nThis type of decoding module is called an nm decoder, similar to the encoding pattern of an 138 decoder. When the decoding module is an nm decoder, the preset decoding data is represented by one byte, where bits 0 to 6 are used to represent the row selection decoding data, and bit 7 is used to represent the latch decoding data. For example, Figure 2 The preset decoding data can be represented as: 1000000, 10000001, 10000010, 10000011, ..., 10001111, a total of 16 sets of preset decoding data.

[0059] like Figure 3 The image shows the output waveform of another decoding module when driving a 64×16 display module (scan mode 1 / 16). The waveforms of channels 0, 1, 2, and 3 correspond to the waveforms of the row selection signals ABCD, and the waveform of channel 5 corresponds to the waveform of the latch signal lat. The changing level signal within one row scan cycle is selected, as shown... Figure 3 As shown in region 31 enclosed by the dashed line, the changing level signals in channels 0-3 within region 31 constitute the first changing level signal, while the second changing level signal is the changing level signal in channel 5. First, the level signals in channels 0-3 are encoded, changing 16 times within one line scan cycle. Based on their changing pattern, each level transition can be represented as: 1111->0000, 0101->0000, 0101->0000, 0101->0000, ..., 1111->1000, 1101->1000, 1101->1000, 1101->1000. Whenever the second changing level signal changes, there is no high-low level transition, and the corresponding latched decoded data is 0, 0, 0, 0, ..., 0. To more clearly represent the level transitions, two bytes are used to represent the encoded data before and after the transition. In this data set, bits 0 to 6 of the first byte represent the data before the transition, and the second byte identifies the data after the transition. The combined preset decoded data can be represented as: (byte1)00001111, (byte2)00000000; (byte1)00000101, (byte2)00000000; (byte1)00000101, (byte2)00000000; (byte1)00000101, (byte2)00000000; ... There are 16 changes within one scan cycle, corresponding to 16 sets of preset decoded data. Please refer to [link to documentation] for details. Figure 4 .

[0060] In the embodiment of the present application, if the change level signal changes K times in a row scanning period, it indicates that the scanning mode of the display module is 1 / K scanning, each change corresponds to a group of preset decoding data, and the corresponding 1 / K scanning corresponds to K groups of preset decoding data. The K groups of change level signals and the K groups of preset decoding data are one-to-one corresponding, and the K groups of preset decoding data are stored in the host computer of the display module as a set as the configuration item corresponding to the decoding module.

[0061] In one embodiment, the driving of the display module according to the configuration item and the content data includes:

[0062] obtaining the configuration item corresponding to the decoding module from the host computer;

[0063] reading the preset decoding data corresponding to the change level signal output by the decoding module from the configuration item;

[0064] determining the current scanning row number according to the preset decoding data;

[0065] driving the corresponding lamp bead row of the display module according to the current scanning row number and the content data.

[0066] When the decoding module is used to drive the display module, the configuration item corresponding to the decoding module can be obtained from the host computer first (the host computer can store the configuration items of multiple decoding modules, and each configuration item corresponds to a different decoding module), the preset decoding data corresponding to the change level signal output by the decoding module is read from the configuration item. These preset decoding data are obtained by encoding the change level signal, and contain row selection decoding data for indicating the row number of the current lighting row (or the current scanning row) and latch decoding data for latching the display content. Based on the preset decoding data, the current scanning row number can be accurately determined, and then the corresponding lamp bead row of the display module is driven according to the current scanning row number and the content data (such as RGB data).

[0067] By abstracting the decoding data corresponding to the decoding module into a configuration item and storing it in the host computer, the adaptation of the display module to different types of decoding modules is realized. When a new decoding module needs to be replaced or introduced, it is not necessary to modify the firmware or programming again, but to simply update the configuration item in the host computer, so that the preset decoding data corresponding to the new decoding module can be automatically obtained. This flexibility greatly improves the compatibility and expansibility of the system, can support multiple decoding modules of different manufacturers or different types, and reduces the difficulty of hardware and software adaptation.

[0068] In summary, the display module and decoding module adaptation method of the embodiment of the present application comprises determining a row scanning period of a display module; obtaining a change level signal of a decoding module in one row scanning period; obtaining preset decoding data according to the change level signal; setting the preset decoding data as a corresponding configuration item of the decoding module; and driving the display module according to the configuration item and content data. The method sets the decoding data corresponding to the decoding module as a flexible configuration item, can realize the adaptation of the display module to various different decoding modules, improves the compatibility and expansibility of the LED display screen system, can effectively reduce the code or firmware modification and update requirements, reduces the development and maintenance costs, and improves the reliability and stability of the system.
