[0043] Embodiment 1

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

[0045] S1: Determine the row scanning period of the display module;

[0046] S2: obtaining a change level signal output by the decoding module within a row scanning cycle;

[0047] S3: obtaining preset decoding data according to the conversion level signal;

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

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

[0050] Specifically, in the display module of the LED display system, the row scanning cycle is used to describe the time interval for the display module to scan all rows in the refresh cycle. In a row scanning cycle, all rows are scanned in sequence to update the display content. The decoding module is responsible for converting the input row selection signal into a control signal that drives the corresponding row of the display module to light up in the LED display control system. The changing level signal in the row scanning cycle is the level signal output by the decoding module during a row scanning cycle. 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 an oscilloscope and other devices. After obtaining these changing level signals, the preset decoding data is obtained according to the changing level signal, that is, the changing law of the changing level signal is encoded, and the changing level signal is converted into the preset decoding data suitable for controlling the display module. Preferably, the preset decoding data includes the row selection data for determining the current display row (that is, the data corresponding to the row selection signal) and the latch data for locking the data content of the current display row (the data corresponding to the latch signal). In other embodiments, it may also include enable data (corresponding to enable signal) and the like. Afterwards, the preset decoding data is used as the configuration item corresponding to the decoding module. The process of using the preset decoding data as the configuration item is actually to store 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. Instead, the configuration item corresponding to the decoding module to be replaced can be directly obtained from the host computer to obtain the preset decoding data, and finally the display module is driven according to the preset decoding data and 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 to the configuration set as a new configuration item. When the display module is subsequently driven, the corresponding configuration item is directly called from the host computer to obtain the corresponding preset decoding data, and the display module can be driven to light up according to the preset decoding data and content data. By setting the decoding data corresponding to the decoding module as flexible configuration items, the display module can be adapted to various decoding modules, which improves the compatibility and scalability of the LED display 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, obtaining preset decoding data according to the conversion level signal includes:

[0052] Acquire a first change level signal and a second change level signal respectively corresponding to the row selection signal and the latch signal of the display module in the change level signal;

[0053] Acquire row selection decoding data according to the first change level signal;

[0054] Acquire latched decoding data according to the second change level signal;

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

[0056] Specifically, the conversion level signal represents the change of the level signal output by the decoding module within a row scanning cycle. In the LED display screen, the row selection signal is often used to control different rows in the display module for display, and the latch signal is used to lock the display content of the current scanning row. Therefore, it is necessary to determine the change level signals corresponding to the row selection signal and the latch signal from the change level signal, that is, the first change level signal and the second change level signal, and encode them. Encode the first change level signal, that is, convert the change of the first change level signal into row selection decoding data. The encoding of the first change level signal can help determine which row is currently scanned. Encode the second change level signal, that is, convert the change of the second change level signal into latch decoding data. After merging these two parts of data, preset decoding data is obtained. These preset decoding data include row selection decoding data for indicating the current scanning row and latch decoding data for locking the display content.

[0057] The following uses two different decoding modules to illustrate how to encode the variable level signal to obtain the preset decoding data.

[0058] like Figure 2 As shown in the figure, it is the output waveform corresponding to a 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 signal ABCD, and the waveform of channel 5 corresponds to the waveform of the latch signal lat. Select a changing level signal within a row scanning cycle, such as Figure 2 As shown in the area 21 surrounded by the dotted line, the changed level signals in channels 0-3 in area 21 constitute the first changed level signal, and the second changed level signal is the changed level signal in channel 5. First, the level signals in channels 0-3 are encoded, which change 16 times in one row scanning cycle. According to the change rule, the row selection decoding data corresponding to the second changed level signal can be obtained as 0000, 0001, 0010, 0011, ..., 1111. Whenever the second changed level signal changes once, the corresponding second conversion level signal has 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 rule is to increase successively. The signals of n channels change m times in one row scanning cycle, and m=2 n, this type of decoding module is called nm decoder, which is similar to the coding rule of 138 decoder. When the decoding module belongs to nm decoder, the preset decoding data is represented by one byte, wherein bit0 to bit6 are used to represent the row selection decoding data, and bit7 is used to represent the latch decoding data. Exemplary, Figure 2 The preset decoding data in can be expressed as: 1000000, 10000001, 10000010, 10000011, ..., 10001111, for a total of 16 sets of preset decoding data.

[0059] like Figure 3 As shown in the figure, it is the output waveform corresponding to 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 signal ABCD, and the waveform of channel 5 corresponds to the waveform of the latch signal lat. Select a changing level signal within a row scanning cycle, such as Figure 3 As shown in the area 31 surrounded by the dotted line, the changed level signals in channels 0-3 in area 31 constitute the first changed level signal, and the second changed level signal is the changed level signal in channel 5. First, the level signal in channels 0-3 is encoded, which changes 16 times in one row scanning cycle. According to its change rule, each level jump can be expressed as: 1111->0000, 0101->0000, 0101->0000, 0101->0000, ..., 1111->1000, 1101->1000, 1101->1000, 1101->1000, and whenever the second changed level signal changes once, the corresponding second changed level signal has no high-to-low level change, and the corresponding latched decoded data is 0, 0, 0, 0, ..., 0. In order to more clearly represent the level change, two bytes are used to represent the encoded data before and after the jump. Among them, bit0 to bit6 of the first byte are used to indicate the data before the jump, and the second byte is used to identify the data after the jump. The preset decoded data after combination can be expressed as: (byte1) 00001111, (byte2) 00000000; (byte1) 00000101, (byte2) 00000000; (byte1) 00000101, (byte2) 00000000; (byte1) 00000101, (byte2) 00000000; ... There are 16 changes in one scanning cycle, corresponding to 16 groups of preset decoded data. For details, please refer to Figure 4 .

[0060] In an embodiment of the present invention, if the changing level signal changes K times within a row scanning cycle, it means that the scanning mode of the display module is 1 / K scanning, each change corresponds to a set of preset decoding data, and the corresponding 1 / K scan corresponds to K groups of preset decoding data. The K groups of changing level signals and the K groups of preset decoding data are corresponded one by one, and the K groups of preset decoding data are stored as a set in the host computer of the display module as the configuration items corresponding to the decoding module.

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

[0062] Obtaining configuration items corresponding to the decoding module from the host computer;

[0063] Reading preset decoding data corresponding to the level-changing signal output by the decoding module from the configuration item;

[0064] Determine the current scanning line number according to the preset decoding data;

[0065] The lamp bead row corresponding to the display module is driven to light up 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 first obtained from the host computer (the host computer can store configuration items of multiple decoding modules, each configuration item corresponds to a different decoding module), and the preset decoding data corresponding to the changing level signal output by the decoding module is read from the configuration item. These preset decoding data are obtained by encoding the changing level signal, and include row selection decoding data for indicating the number of currently lit rows (or currently scanned rows) and latch decoding data for latching display content. Based on the preset decoding data, the current number of scanned rows can be accurately determined, and then the lamp beads of the corresponding rows in the display module are driven to light up according to the current number of scanned rows and content data (such as RGB data).

[0067] By abstracting the decoding data corresponding to the decoding module into configuration items and storing them in the host computer, the display module can adapt to different types of decoding modules. When a new decoding module needs to be replaced or introduced, there is no need to modify the firmware or program again. Instead, the preset decoding data corresponding to the new decoding module can be automatically obtained by simply updating the configuration items in the host computer. This flexibility greatly improves the compatibility and scalability of the system, and can support decoding modules of multiple different manufacturers or different types, reducing the difficulty of hardware and software adaptation.

[0068] In summary, the display module and decoding module adaptation method of the embodiment of the present invention includes determining the row scanning cycle of the display module; obtaining the change level signal of the decoding module within one of the row scanning cycles; obtaining preset decoding data according to the change level signal; using the preset decoding data as the configuration item corresponding to the decoding module; and driving the display module according to the configuration item and content data. The method can realize the adaptation of the display module to various different decoding modules by setting the decoding data corresponding to the decoding module as a flexible configuration item, thereby improving the compatibility and scalability of the LED display system, and at the same time, it can effectively reduce the code or firmware modification and update requirements, reduce development and maintenance costs, and improve the reliability and stability of the system.
