Description

A kind of production method of 2D/3D switching display
Technical field
The invention belongs to 3D field of stereoscopic display.
Background technology
The development of science and technology is never halted, and the renewal speed of electronic product is also make people too plenty for the eye to take it all in.Within 2010, showing, along with film " A Fanda ", the sensational effect caused, 3D Display Technique is known and pursues, and has led the new trend of film industry.Meanwhile, be also unwilling to be outshone in consumption appliance field, and numerous brands have released one after another the 3D computer monitor of oneself, scialyscope or LCD TV, 3D mobile phone.The application of current 3D technology is seen, is cinematographic work or household appliances all have a common feature must wear specialty glasses exactly could to use.But, wear 3D eyes for a long time and the eyes of people can be caused certain injury, especially eyes not yet fully-developed minor, 3D eyes are used to be likely to result in stravismus, amblyopia and other visual problems, its reason is that 3D film uses two camera lenses filmed image simultaneously from different directions, makes film.During projection, with two projectors, two groups of films are synchronized projection, make slightly differentiated two width images overlap in screen.If at this moment having ghost image with eyes direct viewing.After putting on special 3D glasses, left eye can only see left picture, and right eye can only see right picture, and left and right image overlap on optical fundus, is produced the visual effect of 3 D stereo by eyes by brain, and this is very big to the stimulation of brain, often can cause the nerve reactions such as headache.The health of people is created numerous bad impact.Meanwhile, the inconvenience that bathomorphic spectators bring because wearing " dual " glasses is had to suffer untold misery especially.Therefore, current spectacle 3D technology is only as the transitional product in 3D technical development, and replaced by bore hole 3D technology the most at last.
The realization that post lens bore hole shows is mainly by sticking a piece of lenticular sheet on the 2 d display screen, and the focal plane of lenticulation is pasted on the 2 d display screen.The video image that several have horizontal parallax generates the video image after a width synthesis, by the light splitting refraction action of lenticular sheet, propagating the light being respectively arranged with horizontal parallax image to suitable position in different directions, beholder stands in visible area just good 3D display effect.But it is because in image information and has some character images etc. not having 3D effect, placing due to the angle of inclination of post lens causes on a display screen, making the whole 3D resolution shown decline, the beholder made has fuzzy, not see Chu sensation, it does not have the display effect of 3D is good.The display of 2D/3D compatible switching arises at the historic moment in this case.
2D/3D switching principle is introduced: 2D/3D switching device includes double-refraction lens grating 1 (Lenticular screen), liquid crystal light valve 2, polaroid 3 and orientation glass 4 referring to Fig. 1 and Fig. 2, the lower surface patch orientation glass 4 of double-refraction lens grating 1, orientation glass 4 pastes the upper surface of liquid crystal light valve 2 again, and the lower surface of liquid crystal light valve 2 pastes 2D display screen by polaroid 3.
First the light that 2D display screen sends be incident to polaroid 3；Wherein double-refraction lens grating 1 by post lens concave grating substrate 1-1 by filling curing type liquid crystal material 1-2 and carrying out high temperature orientation and ultra-violet curing and make and obtain, post lens concave grating substrate 1-1 is prepared on PET film 1-3 by mould, for positivity liquid crystal, the extraordinary ray refractive index n of liquid crystale> ordinary refraction index n0, array substrate refractive index is npUnirefringence material and n0=np.Liquid crystal light valve 2 includes two pieces of TN box orientation glass 2-1, and the medial surface of two pieces of TN box orientation glass 2-1 is laid with ITO electrode 2-2, filling liquid crystal molecule 2-3 between two pieces of TN box orientation glass 2-1.Fig. 1 is that first the light that 2D display screen sends be incident to polaroid 3 polarization light output to ITO electrode 3 electric power thus supplied of liquid crystal light valve, and liquid crystal molecule 2-3 is under the effect of electric field, and this line polarized light is when by liquid crystal light valve 2, and its polarization direction is not changed.When this line polarized light incides post lens, the polarization direction of this line polarized light is consistent with the long axis direction of the liquid crystal molecule of the liquid crystal material 1-2 in double-refraction lens grating 1, and the liquid crystal molecule 1-2 in double-refraction lens grating 1 shows major axis refractive index, due to ne> npSo that line polarized light reflects at the intersection of liquid crystal material 1-2 and array substrate 1-1, shows thus realizing 3D.Fig. 2 is the not powered situation of liquid crystal light valve 2, the line polarized light of 2D display screen 1 is when by liquid crystal light valve 2, the polarization direction of line polarized light is rotated by 90 °, when this light is to double-refraction lens grating 1, the polarization direction of line polarized light is consistent with the liquid crystal molecule short-axis direction of liquid crystal material 1-2 in double-refraction lens grating 1, and in double-refraction lens grating 1, liquid crystal watch reveals the refractive index n of short axle0=npSo that the emergent light direct projection eventually passing double-refraction lens grating 1 goes out grating, it is achieved 2D shows.
One of vitals of 2D/3D switching device is liquid crystal light valve 2, its operation principle such as Fig. 3 and Fig. 4, figure provides two pieces of TN box orientation glass 2-1 and liquid crystal molecule 2-3, omit ITO electrode 2-2, Fig. 3 is situation about powering up, liquid crystal molecule 2-3 arranges along direction of an electric field, and light beam polarization direction is constant, either directly through；Fig. 4 is not powered situation, and the inner side direction recess of two pieces of TN box orientation glass 2-1 moves towards orthogonal, and liquid crystal divides 2-3 by half-twist, polarization direction also half-twist when light beam passes through.
According to above-mentioned introduce known, existing making 2D/3D switching display at least needs to fit through three times, exist once between lower surface and the orientation glass 4 of double-refraction lens grating 1 soft+firmly fit, exist between the TN box orientation glass 2-1 of this orientation glass 4 and liquid crystal light valve 2 upper surface once hard+firmly fit, exist between polaroid 3 and the 2D display screen of liquid crystal light valve 2 lower surface once hard+firmly fit；Could exporting the 2D/3D switching display required for final people need after above-mentioned three laminatings, technological process is complicated.
Summary of the invention
The invention aims to solve tradition 2D/3D switching display at least need to fit through three times, the problem that technological process is complicated, it is provided that the production method of a kind of 2D/3D switching display.
