Description:

This paper studies the design of a pre-charging circuit in source driver integrated circuits (ICs). We control the charging timing of the AMOLED module to achieve rapid charging effects. For the FHD+ resolution module, operating at a 144Hz frame rate, the speed of the fast charging model is increased by 43%, while the load current is reduced by 8.5%. This innovative fast charging model effectively mitigates the color bias issue caused by insufficient source charging under heavy loads. Furthermore, implementing this fast charging model enables us to enhance the performance of a 165Hz display.
