2D-3D convertible stereo display device

Abstract

The invention discloses a 2D-3D conversable stereo display device, comprising: a device providing image light, a polarized light converter and a lens component, wherein the device providing image light is used for providing image lights of linear polarization, the polarized light converter is used for controllably transmitting the incident image lights of linear polarization completely or incompletely, or rotating the incident image lights into the polarization light vertical to the incident polarization direction, the emergent light is input to the lens component, the lens component comprises a single-refraction lens and a dual-refraction lens which form a combination lens and both comprise a plane part and a relative curve part, the cure parts of the two lenses are wedged with each other, the combination lens can present a convex lens for one of the two polarization light output by the polarization light converter after rotation or no rotation, and can present a plate lens. The 2D-3D conversable stereo display device can freely realize 2D-3D conversion.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a device capable of performing 2D or 3D conversion in any area of ​​the screen. 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 stereoscopic display devices: a slit grating type stereoscopic display device and a microlens array stereoscopic display device. The microlens array stereoscopic display device includes a display panel and a microl...

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

Moreover, the above-mentioned existing 2D-3D conversion cannot realize independent control of each pixel point, cannot display stereoscopic and planar images to the audience at the same time, let alone dynamically display stereoscopic or planar images, and the functions and effects of the display are not satisfactory.
