摘要： In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing). In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.
