Abstract
The invention provides a light modulation unit including a collimating optical layer and an optical film. The optical film has a light exit surface and a light entrance surface opposite to the light exit surface. The collimation optical layer and the light entrance surface of the optical film are disposed relatively. The light exit surface forms a plurality of microstructures, each of which has a height h in the normal direction of the light exit surface and a virtual aperture φ in the x-coordinate axis direction parallel to the light exit surface, and the ratio of the height h to the virtual aperture φ (h/φ) is 0.2 to 1. The light modulation unit of the present invention has the function of adjusting the brightness of anti-peep viewing angles, and can improve the display brightness of front viewing angles through light pattern control.
