Description
Technical field
The invention relates to a kind of method for assembling of display, be particularly to a kind of method for assembling of naked-eye stereoscopic display.
Background technology
It is three-dimensional that (Three-Dimension, 3D) display technique is considered to display most important R﹠D direction after high image quality.Stereopsis is according to stereoscopic vision (StereoVision) principle that sees through human eyes, and promptly human eyes are separated by and are approximately the distance of 65mm and binocular parallax occur and form.Eyes are seen two different bidimensionals being sent to human brain (Two-Dimension, 2D) image, and two images are combined to the degree of depth and stereovision with the regeneration stereopsis in human brain.Therefore, around this principle, desire to show that in flat-panel screens stereopsis needs provide two groups of images that intermesh with emulation binocular vision respectively in same picture, make two to see through polaroid glasses or grating receives two group images respectively again, reach the effect of stereopsis.Yet polaroid glasses are made troubles in the use, therefore develop the naked-eye stereoscopic display that many different designs, see through optical design and directly two group images are sent to left eye and right eye respectively.
Usually naked-eye stereoscopic display (AutostereoscopicDisplay) is to utilize two kinds of technology to reach effect, the firstth, grating (OpticalGrating) formula stereo display technique, its principle is to utilize grating that the picture element that shows left-eye images in the flat-panel screens is covered the picture element that does not allow right eye see, will show right-eye image to cover and do not allow left eye see to reach the effect of stereoscopic vision.Disparity barrier (ParallaxBarrier) for example, the parallax barrier also is divided into driven type and non-driven type.Driven type then for example clips two vertical each other polaroids up and down with one deck liquid crystal panel, then drives the light tight shaded portions that produces raster graphic with electricity when needs form stereoscopic vision.Non-driven type then utilizes the black matrix" (BlackMatrix) in the design liquid crystal panel that light is covered.
Another is a refraction type bore hole stereo display technique, and its principle is the left-eye images picture element to be refracted to left eye, right-eye image picture element be refracted to right eye to produce the effect of stereoscopic vision.For example column convex lens (Lenticular) are to place a slice column convex lens array on the flat-panel screens, each convex lens all corresponds to left-eye images picture element or right-eye image picture element in the array, utilize those convex lens with the left-eye images picture element be refracted to left eye, the right-eye image picture element is refracted to right eye.Another is liquid crystal lens (LiquidcrystalLens), its in addition with the principle of liquid crystal lens with the left-eye images picture element that corresponds to or right-eye image picture element through the driving of liquid crystal layer with the left-eye images picture element be refracted to left eye, the right-eye image picture element is refracted to right eye.
Now, along with the raising of the picture element of display panels, the distance between picture element and picture element is also more close.Therefore, when above-mentioned parallax barrier, column convex lens or liquid crystal lens layer and show that upright accurate of the display panels group of two-dimensional picture aim at just especially important.When the upright aligning of group inadequately accurately the time, the effect of its stereopsis is variation, when serious even can't see stereo-picture clearly.In addition, when organizing upright finishing, still can't learn, need just can learn the effect that group is upright to the actual detection step of exporting stereopsis for the quality that this naked-eye stereoscopic display group is upright.Therefore,, promptly may need to organize again and stand or abandon, cause the raising of manufacturing cost if the naked-eye stereoscopic display that detects is to organize when founding defective products.
