Abstract
A backlight assembly including a light source, a birefringent component and at least one first dimmer is described. In an embodiment, the birefringent component is configured to divide the light incident on the birefringent component into a first polarized light and a second polarized light. In an embodiment, a vibration direction of the first polarized light is different from a vibration direction of the second polarized light. In an embodiment, the birefringent component includes a first region and a second region. In an embodiment, the first polarized light corresponds to the first region, the second polarized light corresponds to the second region, and the first region and the second region at least partially do not overlap in an emission direction of the light. In an embodiment, the first polarized light propagates along a first direction, the second polarized light propagates along a second direction intersecting with the second direction.
