Abstract

The present invention discloses a stereoscopic display device, comprising an image light device for providing linear polarization, and a lens assembly. The lens assembly comprises a lens combination composed of a single refraction index lens and a double refraction index lens, and also comprises a thin film transistor circuit board and a control unit; the oriented transparent electrodes are coated on both two sides of the double refraction index lens, wherein the transparent electrode on one side comprises at least two transparent electrode units which are insulated from each other, the transparent electrode units are connected respectively with the transistors on the thin film transistor circuit board, the control unit and the transistors are connected with the transparent electrode on the other side of the double refraction index lens for controlling, via the transistors, the electric field between the transparent electrode units and the transparent electrode on the other side; under the electric field, the incident polarized light is not refracted when passing through the lens combination, and without the electric field, the incident polarized light is refracted when passing through the lens combination. The 2D-3D conversion can be made at will.

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...
