Abstract
A liquid crystal module includes an array substrate, a color film substrate, and a liquid crystal layer. The array substrate and the color film substrate are disposed oppositely. The liquid crystal layer is disposed between the array substrate and the color film substrate. The array substrate includes a pixel electrode and a capacitor metal layer arranged on a side of the pixel electrode away from the liquid crystal layer. The capacitor metal layer and the pixel electrode form a storage capacitor. The color film substrate includes a reset electrode assembly. In a reset period, the reset electrode assembly is configured to access to a reset voltage signal to orient liquid crystal molecules along a first orientation direction. The reset electrode assembly includes an adjustment structure. During the reset period, the adjustment structure is configured to reduce a capacitive reactance load when the reset voltage signal is turned off.
