Description
Technical field
The present invention relates to a kind of holographic display device and electrochromism module thereof, be meant a kind of holographic display device and electrochromism module thereof that shows stereopsis that supply to turn to especially.
Background technology
At present, in showing stereopsis, have be divided into naked look stereopsis and wear shutter glasses produce two kinds of stereopsis.
See also Fig. 1 and Fig. 2, it utilizes shutter glasses (shutter glass) for prior art and produces the holographic display device synoptic diagram and the synchro control process synoptic diagram thereof of stereopsis.In this holographic display device 1, when backlight 13 light that send through behind the display panels 12, can see left-eye images data and right-eye image data respectively at different time point for left and right two, and generation vision separating effect.The left-eye images data of Alternation Display and right-eye image data must be via a shutter glasses 11 and a control circuit (figure does not show) synchronous operations; It utilizes one to switch the unlatching (On) of signal controlling shutter glasses 11 left eyes and right eye and close (Off); After the reception image of this switching sequence and display panels 12 is synchronous; When showing the left-eye images data, shutter can cover the sight line of right eye.During anti-demonstration right-eye image data, shutter glasses can cover the sight line of left eye.So, the images of left and right eyes image is Alternation Display fast, again through visual persistence effect, and produces stereoscopic visual effect.This kind stereopsis imaging mode is called method timing separation (Time Division) again.
In addition; Also have a kind of wavelength zone point-score (Wavelength Division), the image of right and left eyes is made red partially and green partially picture earlier handle, left eye is red, the green tinted glasses of right eye and the audience wears; Left eye is only seen red left eye visual angle image; Right eye is only seen green right eye visual angle image, utilizes the picture of left and right sides different colours to handle, and goes out stereopsis with construction.
In addition, also has the made holographic display device of a kind of Pu Feilike of utilization effect (Pulfrich effect).This holographic display device comprises a Pu Feilike anaglyph spectacles; This anaglyph spectacles wherein a slice eyeglass more comprises a neutral colour filter (neutral filter); Transmittance through two eyeglasses about making is different; And utilize brain slower a little than bright stimulation to the cognition that darkness stimulates, produce the shadow illusion.Though all can see same image for two, owing to see through optical filter, make that the speed of this transmission image to brain is slower, but and the spatial depth of constructing virtual and produce stereoeffect.
Above-mentioned wearing glasses presents the display mode of stereopsis, and it is because technology maturation, and is widely used in the industry of film, televisor and projector.Yet, because it needs extra wearing glasses, for the user who originally promptly wears myopia or spectacles for long sight; Cause many troubles undoubtedly, and, be prone to produce problems such as health if when being used in public place; And when many people wear this kind glasses; Cause dizziness, nauseating phenomenon easily, and cause physiological burden, make the development of this kind stereopsis technology receive certain limitation.
And look in the stereo display technique in naked, be broadly divided into lens pillar (lenticular), light barrier-type kinds such as (Barrier).Wherein, the lens pillar formula, it is by the convex lens of many elongated vertical bars, arranges continuously along a direction of principal axis, utilizes the principle of light refraction to produce the different views of right and left eyes.Compared to the light barrier-type, because it utilizes the refraction of light to reach the purpose of beam split, so light is good than free of losses, brightness; But in the edge of lens arrangement, the restriction of refraction effect is arranged, cause refraction effect not good; Or when making lens pillar; Because precision control is difficult for, is prone to when resulting in use produce parasitic light, and then influences whole display effect.
In addition, the light barrier-type utilizes the barrier of permutation, penetrates with the light that limits some angle, only lets the view image of some angle, is sent to right and left eyes respectively, to produce stereopsis.Compared to lens pillar, its simple eye image is comparatively clear, yet its structural characteristics cause overall image brightness to reduce, and image analytic degree descends.
Along with development of material technology, because electrochromism (electrochromic) material promptly produces characteristic painted or that discolor after having energising, and be used in gradually as parallax grating, used to produce stereopsis." switching the display device of 2D flat image/3D image display frame " in " integrated electrochromics 2D/3D display ", the notification number of TaiWan, China patent gazette notification number M368088 number M371902 number though it utilizes electrochromic material as the disparity barrier structure that shows stereopsis, yet all lacks dielectric substrate in its structure; Can provide ion to the required ion of electrochromic layer and lack; Make electric driven color-changing part can't produce the reversible reaction of oxidation or reduction and accomplish painted or the variation of discoloring, therefore in fact above-mentioned patent in should implementing, in addition the transparent electrode layer of this disparity barrier device and electrochromic material layer; All be set to barrier pattern; Layering coating, sputter or etching in its manufacture process, and even the accurately contraposition of each lamination, suitable complicated of processing procedure and can improve resistance value so that the response time slack-off; 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.
Moreover existing in order in the technology that shows stereopsis, it only can show stereopsis by single direction.For carry-on portable electronic products such as the mobile phones that use in a large number at present, personal digital assistant, guider; The user only can turn to specific direction with it; Just can watch stereopsis, and the angle of conversion stereo display accordingly, quite inconvenience.
