Convertible automatic stereo display device

Abstract

The invention discloses a convertible automatic stereoscopic display device, which comprises a image light source supply device, a polarized light conversion device and a lens component; the image light source supply device is used for providing a linear polarized light source for images; the polarized light conversion device can directly transmit the incident linear polarized light source without rotation or rotate the incident linear polarized light source into a polarized light vertical to the polarization direction during incidence with control; the emergent light is incident to the lens component; the lens component comprises a single refractive index lens and a birefractive index lens, and a composite lens is formed by the single refractive index lens and the birefractive index lens; both lenses comprise a plane part and a curved surface part corresponding to the plane part; the curved surface parts of the two lenses are matched with each other; the composite lens is presented as a convex lens for one of the two polarized lights of the polarized light conversion device with or without rotation, and a plate lens for the other. The convertible automatic stereoscopic display device has the advantages that, the technical proposal is easy to be realized; the conversion time is short, and the quality is high.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a 2D-3D convertible autostereoscopic display device. Background technique [0002] Humans perceive the depth of objects through the slight difference between what the right and left eyes see, and thus recognize stereoscopic images. This difference is called parallax. Stereoscopic display technology is to create the parallax of the left and right eyes of people through artificial means, and send two images with parallax to the left and right eyes respectively, so that the brain can observe the real three-dimensional objects after obtaining the different images seen by the left and right eyes. a feeling of. There are generally two types of autostereoscopic display devices: slit grating autostereoscopic display devices and microlens array autostereoscopic display devices. The microlens array autostereoscopic display device includes a display panel and a microlens arra...

Problems solved by technology

[0004] Due to the very high precision requirements of the microlens array and the non-flat surface, this process of plating a conductive thin layer or a gradient electrode layer on the surface of the microlens array is very difficult, and it is difficult to ensure the accuracy of the microlens array after the conductive thin layer is plated. Accuracy; and the voltage is applied on the conductive thin layer between the microlens array and the transparent plane plate to form an electric field, the distance of the electric field is large, and the electric field intensity is very small under the same supply voltage, the microlens array and the transparent plate between The time for the liquid crystal director to align with the electric field and the time for the liquid crystal director to return to the original alignment position when the electric field is withdrawn are very long, resulting in a very long response time for the device to switch between 2D and 3D, causing discomfort to the audience's eyes
