Design of Distributed Ultra-High-Definition Resolution Display System

A practical and scalable ultra-high-definition resolution display system for multi-screen display wall is constructed based on multiple distributed low-definition display nodes, and the collaborative processing mechanism between distributed display nodes is the key to the performance of the display system. In order to improve the performance of image synchronization between distributed nodes, a node collaboration mechanism based on IEEE1588 time synchronization protocol and phase-locked loop is proposed. A synchronization processing system applied to ultra-high-definition resolution displays is designed, which not only shortens the image processing time but also improves the image synchronization processing performance. The system synchronization test results show that the maximum display frame difference between splicing display units is 0.47 frame and the average system delay is 98.67ms. The provided system can effectively shorten system data processing time, solve synchronization problems of ultra-high-definition resolution displays, meet requirements of large screen display images, and improve users' experience effect.
