US 12,710,672 B2 · Liquid crystal display and screen clearing method thereof

Abstract

A liquid crystal display includes a display panel and a driving unit. The display panel includes a plurality of resetting sections, which correspond to display a plurality of screens, respectively. There is a first voltage difference between a corresponding one of the column voltages and a corresponding one of the row voltages of one of the resetting sections, and there is a second voltage difference between a corresponding one of the column voltages and a corresponding one of the row voltages of another of the resetting sections. The second voltage difference reaching a second maximum voltage difference value is after the first voltage difference reaching a first maximum voltage difference value by a delay time, so as to clear the screens.
