Analysis and Improvement of Repeated Wake-up Jittering H-line

With the introduction of new concepts such as Industry 4.0, smart manufacturing and smart wearable devices, The TFT-LCD industry has been widely used in all walks of life as the main way for human and computer vision information exchange. Based on the high quality requirements, customers are increasingly demanding verification conditions for their products, which also reveal some problems. This article discusses a type of repetitive wake-up Jittering H-line in the verification process of the customer's complete machine, which is more complicated than the previous jitter stripes. Through the analysis of the defective phenomenon, this topic explores several aspects of the whole system, IC initialization settings, Panel design and TFT characteristics, and conducts simulation based on simulation software to find the cause of the defect and propose effective improvement measures, providing an effective solution for the subsequent new products to circumvent the problem.
