2D/3D(2 dimensional/3 dimensional) image switching display device

Abstract

The invention relates to a 2D / 3D(2 dimensional / 3 dimensional) image switching display device which comprises an image display unit and an image switching unit combined with the surface of the image display unit, wherein the image switching unit comprises a first transparent substrate and a second transparent substrate; the surfaces of the first transparent substrate and the second transparent substrate are respectively and correspondingly provided with a first transparent conductive element and a second transparent conductive element; an electrochromic layer and an electrolytic layer are arranged on the first transparent substrate and the second transparent substrate; accordingly, when the image display unit is converted from the plane image display into the solid image display, the first and second transparent conductive elements are electrically conducted, thereby converting the electrochromic layer from transparent state to a dark color shading area and generating no folded grain when an solid image divided into a left image and a right image is received by eyes; when the solid image is displayed by the 2D / 3D image switching display device, the solid image can be displayed directly without using an additional parallax barrier shielding device; and the image switching unit can switch different shielding angles according to an image direction of the image display unit, so that a user is capable of viewing the solid image in all directions of a device.

Description

technical field [0001] An "image switching display device" particularly refers to a 2D / 3D image switching display device capable of switching between 2D image and 3D image display states. Background technique [0002] The principle of the well-known stereoscopic image display technology is to use binocular disparity to receive different images through the left and right eyes respectively, and finally fuse them into a stereoscopic image in the brain. In naked-eye stereoscopic display technology, according to its structure, it can be roughly divided into two types: lenticular lens and barrier type. The above two structures have their own advantages and disadvantages. Convex lenses are arranged continuously along one axis, and use the principle of optical refraction to produce different views of the left and right eyes. Compared with the light barrier type, because it uses the refraction of light to achieve the purpose of splitting light, there is no loss of light and good brig...

Problems solved by technology

[0006] Both of the above two patents use electrochromic materials as parallax barrier devices for displaying stereoscopic images, but the common defect in their structures is that they lack the necessary electrolyte layer for electrochromic devices, because they lack the ability to provide ions to the electrochromic layer. electrolyte layer, the electrochromic device will not be able to produce a reversible reaction of oxidation or reduction to complete the coloring or decolorization change, so the two patents should not be implemented in practice; in addition, the transparent electrode layer of the parallax barrier device and the electrochromic material Layers are all set as a fence pattern, layered coating, sputtering or etching in the manufacturing process, so that each stack must be accurately aligned, the manufacturing process is quite complicated, and all stacks are set as a fence pattern, resulting in each A hollow area formed between a fence and the fence will affect the overall light penetration, refraction or reflection. Even for general 2D display, it may affect the image quality of the display, causing problems such as color difference or uneven brightness, and the hollow area between the fences will also be affected. Reduce the strength and service life of the fence; and another structure embedded in the liquid crystal display substrate in the M368088 patent is to embed a fence pattern into an insulating transparent material. Although the thickness of the liquid crystal display with three-dimensional images can be reduced, the actual manufacturing process is also is quite complicated

[0007] In addition, although the above-mentioned conventional technology can be used for switching between two-dimensional display and three-dimensional display, for handheld devices that can change viewing angles arbitrarily, the angle of three-dimensional display cannot be changed accordingly, and 3D images must be viewed in a fixed direction.
