Abstract
A light guiding component is provided in an eyeball tracking module which includes a first substrate and a second substrate disposed opposite to each other, a first electrode disposed on the first substrate, a second electrode disposed on the second substrate, and at least one liquid crystal structure disposed between the first electrode and the second electrode. The liquid crystal structure includes liquid crystal molecules. The first electrode and the second electrode are configured to control a deflection direction of the liquid crystal molecules with an applied voltage, such that a light ray incident to the light guiding component, which meets a threshold condition, is emitted along a predetermined direction.
