Therefore, the image display unit is converted into 3D image display from plane image display, the state of the electrochromism layers can be converted into a deep shading state so that better shading effect is obtained, 3D images of a left eye image and a right eye image are distinguished so that moires can not be generated during receiving by naked eyes, and a 3D image can be directly displayed without additionally using a parallax barrier shading device.
Description
Technical field
The present invention relates to a kind of image switching display device, be meant a kind of 2D/3D image switching display device that switches 2D image or 3D image show state that has especially.
Background technology
The stereopsis display technique of being known at present, its principle is to utilize binocular parallax (Binoculardisparity), receives different images respectively through right and left eyes, is fused into a stereopsis at brain at last.In the bore hole stereo display technique, be broadly divided into two kinds of lens pillar (Lenticular) and light barrier-types (Barrier) according to its structure, above-mentioned two kinds of structures respectively have its relative merits; Wherein lens pillar is to be arranged continuously along a direction of principal axis by the convex lens of many elongated vertical bars, utilizes the principle of light refraction to produce the different views of right and left eyes, compared to the light barrier-type; Because of it is to utilize the refraction of light to reach the purpose of beam split; So light is good than free of losses, brightness, but its refraction restriction is arranged and make refraction effect not good in the edge of lens arrangement, or because the error when making lens pillar; Lens surface is difficult for factors such as smooth; Have the generation of parasitic light, cause the fuzzy stereopsis of part, and influence the display effect of whole 3D image; In addition; The light barrier-type then is that the light that utilizes the barrier of permutation to limit some angle penetrates; Only let the view image of some angle be sent to right and left eyes respectively to produce stereopsis, compared to lens pillar, its simple eye image is comparatively clear; But its congenital architectural feature then can cause degradation defective under the brightness reduction, image analytic degree of overall image.
In addition, general 3 d display device only can show stereopsis; Can't switch to flat image and stereopsis, main cause be lens pillar (Lenticular) or optical screen barrier (Barrier) be combined in general display after, all flat images through lens pillar (Lenticular) or optical screen hinder (Barrier) after; Just can be divided into left-eye images and right-eye image, only the stereopsis of external hanging type shows module, in the time need not showing stereopsis; The stereopsis of external hanging type is shown that module is by disassembling on the display; But this kind mode is when reality is used, and aligned position just can not produce problems such as image analytic degree decline or deflection accurately; Therefore, just there is the dealer to develop the holographic display device of changeable demonstration stereopsis or flat image.
Like the tw Taiwan patent gazette; The display device of the switching 2D flat image that notification number is M371902 number/3D stereopsis display frame; It comprises the display surface that a flat-panel screens and a disparity barrier panel are located at this flat-panel screens, and wherein this disparity barrier panel comprises a barrier pattern, and it comprises one first electrochromics material layer and one second electrochromics material layer; And when a 2D flat image show state; This barrier pattern, this first electrochromics material layer and this second electrochromics material layer are transparent, and when a 3D stereopsis show state, this barrier pattern is a light tight pattern; And this first electrochromics material layer has one first color, and this second electrochromics material layer has one second color.
Like the tw Taiwan patent gazette, the display device of the switching 2D flat image that notification number is M368088 number/3D stereopsis display frame, it comprises: one first substrate; The below of first substrate is located in one disparity barrier unit; One colored light-filtering units is located at the below of disparity barrier unit; One common electrode is located at the below of colored light-filtering units; One liquid crystal cells is located at the below of common electrode; A plurality of membrane transistors are located at the below of liquid crystal cells; One second substrate is located at the below of a plurality of membrane transistors; And a light source is located at the below of second substrate; Carry out the modulation of flat image and stereopsis and reduce thickness and the assembly cost that has display device now through the disparity barrier unit.
Above-mentioned two pieces of patents all are to utilize electrochromic material to be used as showing the disparity barrier device of stereopsis; But the common defects in its structure; The necessary dielectric substrate that all lacks electrochromic device for want of can provide the dielectric substrate of ion to electrochromic layer, and electrochromic device can't produce the reversible reaction of oxidation or reduction and accomplish painted or the variation of discoloring; Perhaps its painted speed of discoloring is very slow, so in fact these two pieces of patents should be implemented; In addition, the transparent electrode layer of this disparity barrier device and electrochromics material layer all are set to barrier pattern; Layering coating, sputter or etching in its manufacture process, and even the accurately contraposition of each lamination, the complicacy that processing procedure is suitable; And all lamination all is set to barrier pattern; Cause forming hollow region in the middle of each fence and the fence, will influence overall light and penetrate, reflect or reflect, both having made is that general 2D shows; Also possibly influence the image quality of display, cause problems such as aberration or brightness disproportionation; And another embeds the structure of LCD base material in the M368088 patent, is arranged on the insulativity transparent material with the mode of barrier pattern, though can reduce the thickness of the LCD of stereopsis, in fact processing procedure also is quite complicated.In addition, above-mentioned known techniques is all sandwich structure, and when it was used to combine display, no matter plane or stereopsis showed, problems such as all influential overall image brightness, quality.
Summary of the invention
Because above-mentioned demand, the inventor studies intensively, and long-pending individual is engaged in the many years of experience of this cause, designs a kind of brand-new 2D/3D image switching display device eventually.
