Optical film and three-dimensional display applying same

Abstract

The invention relates to an optical film and a three-dimensional display applying the same. The optical film comprises a collector lens array layer and a prism array layer, wherein the collector lens array layer is provided with a plurality of collector lenses, is configured at the front of pixels and is provided with at least a first part and a second part which are not overlapped mutually; and the prism array layer at least comprises a first prism sub-array which is provided with a plurality of first prisms, the first prisms are used for leading lights penetrating through the collector lenses of the first part of the collector lens array layer to move along a first direction and leading the lights penetrating through the collector lenses of the second part of the collector lens array layer to move along a second direction, and the first direction and the second direction are different. The optical film disclosed by the invention can be directly attached on a display with convenient installation and is configured at the front of a display panel, the manufacturing procedure of the original display panel or backlight module does not need to be changed, thus the cost and the complexity of the manufacturing procedure can be greatly reduced.

Description

technical field [0001] The invention relates to an optical film and a three-dimensional display, in particular to a three-dimensional display using an optical film. Background technique [0002] In the past, to achieve the effect of 3D image display, most of them were achieved by wearing assistive devices, such as special polarized glasses. In the current common stereoscopic display technology, a light source, such as a cold cathode ray tube, is designed on both sides of the backlight module. By controlling the light sources on both sides to turn on at different timings and controlling the pixels to output different image signals at different timings, the left and right eyes of a person receive different images to achieve a stereoscopic display effect. [0003] However, in the practice of designing a light source on both sides of the backlight module, it is necessary to add an optical element to change the path of the light in the backlight module, which increases the compl...
