Abstract

The invention discloses a cascading application system capable of omitting peripheral resistors and capacitors and reducing interference and an implementation method thereof. The cascading applicationsystem comprises a single-path cascading application system and a multi-path cascading application system, and the system comprises a plurality of groups of bound and packaged LED lamps, a pluralityof cascading chips and a controller. According to the cascade application system and the implementation method thereof, a universal original application system is adopted, the use cost is not increased, a resistor and a capacitor are omitted, system interference is reduced, and the cascade LED display application system is safely, effectively, correctly and stably used.

Description

technical field [0001] The invention relates to a cascaded application system and its realization method which omits peripheral resistors and capacitors and reduces interference. Background technique [0002] The LED display cascade application system includes a controller and a cascade chip, etc. The controller sends data, and the cascade chip receives and displays the data and forwards and transmits the data. The existing LED display cascade application system is divided into LED display series application system and LED display parallel application system. [0003] LED display parallel application system, the controller generates sending data and connects the input channels of all parallel chips, and obtains the data of this chip from the parallel data line through different chip addresses of the parallel chip and displays them. The LED display parallel application system has high reliability. If a parallel chip in the LED display parallel application system is damaged, ...
