Abstract
This invention disclose a display system capable of converting plane/stereo images including a display device and a parallax fence, which can be converted to a total penetration mode so as to convert the stereo images to plane images. This invented parallax fence is composed of a torsion nematic obstructor, a diffuser is set inside of carry plate replaced by a plastic base, so that the distance between the visual position of the fence and the display pixel of the display device is rather short to provide a shorter stereo image distance.
Description
Technical field
The present invention relates to the display system of stereopsis, relate in particular to the display system of the convertible plane/stereo image that uses parallax barrier.
Background technology
See also Fig. 1, patent for No. 6108029 bulletin of United States Patent (USP) notification number (USPN), but this Patent publish a kind of display system of plane/stereo video conversion, module 1 backlight and parallax barrier 2 are seated in the both sides of display device 3 (penetration panel) respectively, parallax barrier 2 has two kinds of patterns such as pattern that penetrates entirely (Transmissive Type) and fence (Barrier) pattern, parallax barrier 2 is by a switch 12 controls, parallax barrier 2 can be changed, with conversion plane image and stereopsis in penetrating two kinds of patterns of pattern and fence pattern entirely arbitrarily.
Please consult Fig. 2 again, its display device is LCD 4 (the Liquid Crystal Display with a module 7 backlight; LCD), but cooperate a parallax barrier 2 to constitute the display system of plane/stereo video conversion, its parallax barrier 2 is made of twisted nematic breaker (Twist Nematic Shutter), its structure is the framework of polaroid 5-support plate 6-liquid crystal layer 8-support plate 6-polaroid 5, but because the polaroid 5 of parallax barrier 2 inboards can be shared with the polaroid 5 in LCD 4 outsides, therefore the polaroid 5 of parallax barrier 2 inboards can omit, under this framework, the visual position 9 of its parallax barrier 2 is positions of front side polaroid 5, and the display pixel 10 of LCD 4 is positioned on the front side polaroid 5 of LCD 4, the visual position 9 of parallax barrier 2 is called object distance d with the distance of display pixel 10, the fringe spacing of parallax barrier 2 is Δ p, the left side of LCD 4, the spacing of right display pixel 10 is Δ L, the eyes distance of human eye 11 is S, human eye 11 is called sighting distance D from the distance of the visual position 9 of parallax barrier 2, the distance of Δ p is about the twice of Δ L, d=Δ L (D+d)/S wherein, Δ p again, Δ L, S is subject to the resolution requirements of human eye 11 and LCD 4, so generally it is considered as fixed value, adopt p=0.016 centimetre of Δ at this, Δ L=0.008 centimetre, S=6.5 centimetre, object distance d tries to achieve via measurement and is about 0.08 centimetre, by above-mentioned arithmetic expression as can be known, the length of object distance d and sighting distance D is positive correlation, and the minimum three-dimensional imaging distance of this existing structure, learn that via after calculating D is about 60 centimetres, obviously itself and be not suitable for the display of medium and small-sized.
Please consult Fig. 3 again, patent for No. 5969850 bulletin of United States Patent (USP) notification number (USPN), with as can be known aforementioned, its support plate 6 with LCD 4 is removed one, shorten object distance d, so that sighting distance D reaches about 35 centimetres, though it can meet the range of application of medium and small-sized display, but it must plate mould (coating) in the both sides of support plate 6, etching (etch), orientation multiple tracks processing procedures such as (rubbing), obviously it plates mould at support plate 6 single faces with prior art adopts, etching, the panel processing procedure of orientation has sizable difference, therefore its production cost is quite high, does not obviously meet the demand of production in enormous quantities.
Summary of the invention
Fundamental purpose of the present invention is to address the aforementioned drawbacks, for avoiding the existence of this defective, the present invention is on the basis of using support plate single face processing procedure, change the making flow process of parallax barrier, the visual position of parallax barrier and the distance (object distance) of display device display pixel are shortened, and then make sighting distance can meet the range of application of medium and small-sized display.
The present invention is a kind of display system of convertible plane/stereo image, it includes a display device, one parallax barrier, parallax barrier is located at the outside of this display device, this parallax barrier is arranged with one second polaroid from inside to outside in regular turn, one second support plate, one liquid crystal layer, one first polaroid, with one first support plate, the electrode that the one side of close this liquid crystal layer of this first support plate and this second support plate has certain patterns, handle through orientation on two surfaces of this liquid crystal layer contact, this parallax barrier utilizes the control of external voltage, by the electrode on this first support plate and this second support plate, control the molecules align of this liquid crystal layer, can conversion arbitrarily in penetrating two kinds of patterns of pattern and fence pattern entirely with this this parallax barrier.
The existing structure of object distance of the present invention in view of the above reduces approximately half, and its sighting distance is about 35 centimetres (cm), can meet the range of application of medium and small-sized display; The present invention also utilizes the technology of plastic liquid crystal panel (plastic LCD) in addition, and support plate is replaced with plastic base (plasticfilm), and it can further reduce the distance of object distance, to reduce sighting distance.
