Embodiment Construction

[0031] Such as figure 1 As shown, it is a flowchart of a method for processing LED display data according to an embodiment. This method inputs the display data step by step to multiple cascaded processing circuits, combining figure 2 and image 3 , a plurality of processing circuits D1, D2, D3, ..., DN are cascaded in sequence, each processing circuit includes a data input terminal Din and a forwarding output terminal Dout, and each processing circuit obtains 24-bit display data. image 3 In , before each processing circuit is reset (RESET), it represents the data that has passed through the processing circuit, and after RESET, it represents the corresponding data saved by the processing circuit. The method comprises the steps of:

[0032] S10: Each processing circuit receives and stores the first 24 bits of data in the input data.

[0033] S20: regenerate and forward the remaining data to the next-level processing circuit.

Abstract

The invention relates to an LED (Light-Emitting Diode) display data processing method. Display data is input into a plurality of cascaded processing circuits stage by stage, and the method comprises the following steps of: receiving and storing the first 24-bit data in the input data by each processing circuit; and regenerating the rest data, and forwarding the regenerated rest data to a next-stage processing circuit. In addition, the invention also provides an LED display data processing device for implementing the method, which comprises a plurality of cascaded processing circuits, wherein each processing circuit comprises a transmission module, and each transmission module is used for receiving and storing the first 24-bit data in the acquired data, regenerating the rest data and forwarding the regenerated rest data to the next-stage processing circuit. In the LED display data processing method and device, before forwarding the data, each processing circuit regenerates the data firstly to reduce the attenuation of data signals so as to adapt to remote transmission.

Description

【Technical field】 [0001] The invention relates to LED displays, in particular to a method and device for transmitting LED display data. 【Background technique】 [0002] In the technical method of single-line high-speed data transmission of display data of LED driver integrated circuits, the DMX-512 protocol (a signal control protocol for digital equipment in the lighting industry, which is an international protocol) or similar transmission methods is mainly used to realize this. The driving integrated circuit of the transmission scheme adopted by the technology generally directly adopts the method of direct drive from input to output for cascade transmission. The advantage of this technology is that it is simple to implement. [0003] In practical applications, due to factors such as inconsistency in the process of integrated circuit chips and changes in the application environment, the pulse width that effectively represents the data information in the process of transmittin...
