Three-dimensional display with changeable parallax barrier pattern

Abstract

The invention discloses a three-dimensional display with a changeable parallax barrier pattern, comprising a display panel and a parallax barrier device, wherein the parallax barrier device is arranged on the display panel and comprises a first substrate, a second substrate, a liquid crystal layer and a plurality of barrier pixels; and the first substrate and the second substrate are arranged oppositely, and the first substrate is arranged between the second substrate and the display panel. The liquid crystal layer is arranged between the first substrate and the second substrate. All barrier pixels are provided with at least one switching component for respectively and independently controlling all the barrier pixels so as to form the changeable parallax barrier pattern.

Description

Stereoscopic display with changeable parallax barrier pattern technical field The present invention relates to a 3D display with a changeable parallax barrier pattern, in particular to a 3D display with a switching component for separately controlling each barrier pixel to form a changeable parallax barrier pattern. Background technique General stereoscopic display technology can be roughly divided into two categories: need to wear special glasses and do not need to wear special glasses. Among them, the stereoscopic display technology that does not need to wear special glasses is also called naked-eye stereoscopic display technology, and the barrier type (BarrierType) ) stereoscopic display technology is a kind of naked-eye stereoscopic display technology. Barrier stereoscopic display technology is to add a black and transparent linear barrier (Barrier) pattern in front of a general display, and this barrier pattern allows one of the viewers to only see the picture displa...

Problems solved by technology

However, the switchable barrier 3D display generally utilizes a passive barrier display device in front of the display panel. The passive barrier display device can only simply present a preset striped barrier pattern to produce a comprehensive 3D display effect. Or without any barrier pattern to show the general 2D display effect

Therefore, since the barrier pattern of the known barrier 3D display cannot be adjusted arbitrarily, the effect of 3D display cannot be achieved when the viewer needs to transpose the 3D display or view it from a different viewing angle.

At the same time, when it is necessary to display two-dimensional and three-dimensional images on the same screen at the same time, the known barrier-type stereoscopic display cannot achieve a good display effect due to the fixed barrier pattern.
