This work proposes a mini-LED driving circuit compensating for threshold voltage variations of the LTPS-TFTs and VSS I-R rise. The simulation results indicate that the relative current error rates are less than 10%. Therefore, the proposed circuit providing a uniform image is appreciated for mini-LEDs backlight applications.
