The low‐frequency image brightness of the VRR mode display will decrease due to an increase in leakage time, causing the display to flicker when switching between different frequencies, seriously affecting user usage. By utilizing VDF technology (VRR De‐Flicker), on the one hand, digital voltage compensation is applied to low‐frequency images to maintain consistent brightness at different frequencies, and on the other hand, the Vcom voltage is dynamically adjusted to suppress pixel leakage. Ultimately, the goal of improving flicker is achieved.
