2D/3D (two-dimensional/three-dimensional) switching type stereoscopic display and control method thereof

Abstract

The invention provides a 2D/3D (two-dimensional/three-dimensional) switching type stereoscopic display and a control method thereof. The 2D/3D switching type stereoscopic display comprises a display panel, a polarization rotator and a lens component, wherein the display panel is used for providing an image with polarization direction; the polarization rotator is used for rotating the polarization direction of the image so as to lead the 2D/3D switching type stereoscopic display to be switched between a 2D display state and a 3D display state; the lens component is provided with a first direction and a second direction which are mutually vertical; and in theory, the lens component generates a non-lens effect for the images with the polarization directions positioned in the first direction, and generates a lens effect for the images with the polarization directions positioned in the second direction. The polarization rotator is configured to lead the polarization direction and the first direction or the second direction to form an included angle less than 45 degrees. By adopting the method, the mismatch of refractive index of the lens component in the 2D display state or the distance mismatch between the display panel and the lens component in the 3D display state can be effectively compensated, so that the display effect can be improved.

Description

A 2D / 3D switching stereoscopic display and its control method 【Technical field】 The invention relates to the field of stereoscopic display, in particular to a 2D / 3D switchable stereoscopic display and a control method thereof. 【Background technique】 Humans perceive the depth of objects through the slight difference between the objects seen by the right eye and the left eye, 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 pictures with a certain parallax to the left and right eyes respectively, so that the brain can produce the feeling of observing real three-dimensional objects after acquiring different images seen by the left and right eyes. . There are generally two types of stereoscopic displays: a slit grating stereoscopic display and a microlens array stereoscopic display. Wherein, the microlens array ster...
