Abstract: A spatial light modulator (SLM) includes a first liquid crystal panel and a second liquid crystal panel that are oppositely configured, and a polarization adjustment part configured between the first liquid crystal panel and the second liquid crystal panel. An alignment direction of the first liquid crystal panel is parallel to an alignment direction of the second liquid crystal panel. The first liquid crystal panel is configured to perform a phase modulation on incident linear-polarized light. The polarization adjustment part is configured to rotate, by a preset angle, a polarization direction of linear-polarized light exited from the first liquid crystal panel. The second liquid crystal panel is configured to adjust a polarization state of linear-polarized light exited from the polarization adjustment part to adjust an amplitude of exited light.

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.
