Problems solved by technology

However, since EP1793623 uses a normal black mode LCD panel as a parallax barrier, the part without electrodes always displays black, so the panel cannot be used for 2D and 3D display, which limits the function of the display

Embodiment Construction

[0033] Certain terms are used throughout the specification and claims to refer to particular elements. It should be understood by those skilled in the art that manufacturers may refer to the same element by different terms. The patent application scope of this specification and claims does not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for distinction. The term "comprising" mentioned throughout the specification and claims is an open-ended term, so it should be interpreted as "including but not limited to", which will be described here first.

[0034] refer to Figure 5 and Figure 6 , Figure 5 and Figure 6 is a schematic diagram of a preferred embodiment of the stereoscopic display device of the present invention, wherein Figure 5 is a schematic cross-sectional view of the stereoscopic display device of the present invention, Figure 6 for Figure 5 The top view of part I.

Abstract

The invention relates to a parallax barrier and stereo display device produced by the parallax barrier. The parallax barrier comprises a first base plate; a plurality of first electrodes which are set on the first base plate and paralleled with each other and extend along a first direction; a transparent insulation layer on the first base plate and a plurality of first electrodes; a plurality of second electrodes on another side of the transparent insulation layer opposite to the first electrodes, wherein the second electrodes are paralleled with each other and extend along the first direction; a second base plate opposite to the first base plate; a common electrode between the second base plate and the transparent insulation layer; and a liquid crystal layer between the common electrode and the second electrodes; wherein the first electrodes and the second electrodes are in staggered arrangement and partly overlap on vertical direction. The stereo display device comprises an image display element and a parallax barrier. The device freely switches between 2D / 3D display modes with good display effect.

Description

technical field [0001] The invention relates to a parallax barrier and a stereoscopic display device made of the parallax barrier, in particular to an automatic stereoscopic display device which can freely switch between 2D / 3D display modes. Background technique [0002] After years of research, several display modes have been developed in the stereoscopic display technology, so that the observer can have a stereoscopic vision. The so-called stereo vision is mainly to apply different images to the left eye and right eye, so that the brain can analyze and overlap them, and then perceive the layering and depth of the viewed objects, thereby generating a three-dimensional effect. Therefore, the stereoscopic display device displays the left-eye signal and the right-eye signal to the observer's left eye and right eye respectively through a certain technology, so that the observer can feel the image content and have a three-dimensional effect. Refer to figure 1 . Such as figure...
