Abstract
A lens assembly for display includes a display, a lens assembly, and a prism assembly. The display emits a first light beam. The prism assembly includes a first, second prisms, and an optical multilayer film, wherein the first prism includes a first, second, and third surfaces; the second prism includes a fourth, fifth, sixth, seventh, and eighth surfaces; and the optical multilayer film is disposed between the third and fifth surfaces. A second light beam enters the first prism through the first surface and exits by the second surface. The first light beam exits the lens assembly and enters the second prism through the eighth surface, and exits the first prism by the second surface. The lens assembly and the prism assembly satisfy: 0.80%≤E/E≤0.95%; wherein Eis an energy of the first light beam emitted from the display and Eis an energy of the first light beam passes through the lens assembly.
