一种LED全彩色显示屏控制系统技术方案

本实用新型专利技术公开了一种ＬＥＤ全彩色显示屏控制系统，该系统由发送板、主控系统和副控系统三部分组成，其中发送板解码原始的视频信号，并把信号作相应的格式传换，压缩，再转成适合远距离传输的ＬＶＤＳ信号或者光信号，发送到主控系统；主控系统接收来自发送板的信号，解码后，作灰度变换，并把信号分配到副控系统中去，主控系统并不直接控制显示；副控系统是整个系统的核心，负责灰度生产，格式编码的最后一级任务，直接决定显示质量，直接控制ＬＥＤ驱动ＩＣ。采用该系统后，控制面积显著缩小，从而传输距离减小，提高了时钟频率，从而提高了刷新频率。（*该技术在2016年保护过期，可自由使用*）

LED full color display screen control system

The utility model discloses a full color LED display screen control system, the system sent by the board, main control system and auxiliary control system composed of three parts, which are sent in decoding the original video signal, and the signal for the corresponding format change, compression, and then converted into LVDS signal or light signal suitable for long-distance transmission and sent to the main control system; main control system receives signals from the transmitting board for decoding, gray-scale transformation, and the distribution of signals to auxiliary control system, main control system does not directly control display; auxiliary control system is the core of the whole system, responsible for the production of gray, format encoding of the last stage of the task and directly determines the display quality, direct control of the LED driver IC. After adopting the system, the control area is significantly reduced, the transmission distance is reduced, and the clock frequency is increased, thereby improving the refresh frequency.
