Reliability Design for High Integration LED Display Driver Circuit
YANG Xiong
Abstract：High integration is the dominant theme in the development of LED display panel technology.As the core component of LED display units,the reliability of the driving circuit directly affects the display quality,service life,and user experience.However,voltage backflow during the driving process can adversely impact the stability and longevity of LED light-emitting units.This article systematically elaborates on the reliability design strategies for highly integrated LED display driving circuits,thoroughly analyzes the main factors leading to LED device failure,and focuses on how to enhance the overall product reliability through back-voltage protection and driving optimization.Experimental results show that the optimized driving circuit increases the product lifespan by 4.7 times and improves failure-free rate from 60.0%in traditional driving circuits to 94.2%.
