Abstract

The invention discloses a simple and universal full-hardware control system of a display screen, particularly relates to the technology of dot matrix display screen control, and belongs to the technical field of an intelligent control system. The simple and universal full-hardware control system of the display screen comprises a central processing unit (CPU) control module, a memory module (random-access memory (RAM) or electrically erasable read only memory (EEROM)), a signal control module, a row selection module, a light-emitting diode (LED) dot matrix module, a parallel to series module and a plurality of series to parallel modules. The memory module is respectively in data connection with the CPU control module, the signal control module and the parallel to series module, the control ends of the parallel to series module and the row selection module are respectively connected with the signal control module, the parallel to series module is connected with the row section module, the plurality of series to parallel modules are configured in dot matrix mode and connected with the row selection module, and the series to parallel modules which are configured in dot matrix mode is correspondingly connected with the LED dot matrix module.

Description

technical field [0001] The invention relates to a simple and universal all-hardware control system for a display screen, in particular to a dot-matrix display screen control technology, which belongs to the field of intelligent control technology. Background technique [0002] With the increasing popularity of computers, information distribution platforms based on computer control are becoming more and more important. However, the control system of the digital dot-matrix display always needs to be changed according to the needs of users, which wastes manpower and material resources. In order to solve this problem, it is necessary to design a general hardware control system. Contents of the invention [0003] The purpose of the present invention is to provide a universal, simple and convenient, all-hardware display screen control system, which can conveniently and effectively meet customer needs. [0004] To achieve the above object, the present invention adopts the follo...
