Problems solved by technology

[0004] However, the above-mentioned device can only operate on polarized light, and cannot operate on natural light, resulting in a serious loss of image brightness. Moreover, the above-mentioned existing 2D-3D switching cannot realize independent control of each pixel, and cannot simultaneously display three-dimensional and two-dimensional images to the audience. Graphics, display features and effects are not as good as expected

Abstract

The utility model discloses a 2D to 3D switchable stereoscopic display unit, comprising a display panel and a plurality of lens components; the lens components comprise two composite lens and a half-wave plate and each composite lens comprises a single refraction lens and a double refraction lens which can be powered on to form an electric field; when not powered on, natural light is beamed in from one composite lens, producing normal light without refraction and abnormal light with refraction which is beamed into the other composite lens through the half-wave plate rotating ninety degrees; normal light, which is produced after rotating, is transmitted without refraction and abnormal light is refracted by the other composite lens; when powered on, natural light is transmitted from a composite lens without refraction and penetrates through the half-wave plate before transmitted by the other composite lens without refraction. Thin film transistor circuit also can be adopted for independently controlling partial areas. The utility model can make 2D and 3D switch display for full screen or partial area under the condition that brightness is not lost.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a device capable of switching between 2D and 3D 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 microlens...
