Embodiment Construction

[0033] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following paragraphs the invention is described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description.

[0034] Figure 4 It is a schematic cross-sectional structure diagram showing the 3D / 2D switchable stereoscopic image display device of this embodiment. Figure 6 and Figure 7 yes Figure 4 Magnification of the dotted box in the shown display device. Figure 6 It shows the state where no voltage is applied to the liquid crystal layer of the liquid crystal lens panel, and the director of the liquid crystal is parallel to the substrate (glass substrate) sealing the liquid crystal (corresponding to 2D display mode). Figure 7 It shows the state where a voltage is applied to the liquid crystal layer of t...

Abstract

The invention discloses an electronically controlled liquid crystal lens panel and a 3D (three-dimensional) / 2D (two-dimensional) switchable stereo display device. The crosstalk in the center of an electrode of the electronically controlled liquid crystal lens panel can be reduced by reducing the width of an electrode at an edge of a lens; a wide field angle can be formed under the condition of high resolution; the electronically controlled liquid crystal lens panel comprises a first substrate and a second substrate which are opposite to each other; a plurality of ribbon-shaped electrodes which are arrayed in parallel are arranged on the inner side of the second substrate, and are made of transparent conductive materials; each ribbon-shaped electrode comprises a plurality of repeating units; each repeating unit comprises a first electrode and second electrodes positioned on two sides of the first electrode; a liquid crystal lens area is limited by each repeating unit; and under the conditions that the distance between each two liquid crystal lens areas is set as D, the width of each first electrode is set as W1, and the width of each second electrode is set as W2, the liquid crystal lens areas, the first electrodes and the second electrodes meet the following relation: 0.005<W2 / D<0.05, W2<W1.

Description

technical field [0001] The invention relates to the field of electrically controlled liquid crystal lenses, in particular to an electrically controlled liquid crystal lens panel and a 3D / 2D switchable stereoscopic display device including the electrically controlled liquid crystal lens panel. Background technique [0002] Currently, 3D display devices are becoming more and more well known, and 3D display modes mainly include glasses 3D mode and glasses-free 3D mode. The display device in the glasses 3D mode needs to wear special glasses. The left eye lens and the right eye lens respectively allow linearly polarized light with different polarization directions to pass through, so that the images viewed by the left eye and right eye are images formed by linearly polarized light with different polarization directions. , the brain integrates the left-eye image and the right-eye image to present a stereoscopic image. Because people need to wear special glasses when viewing the i...
