Description
Technical field
the present invention relates to a kind of display accessory and preparation method thereof, be specially liquid crystal cell switched for 2D and 3D and preparation method thereof.
Background technology
the liquid crystal cell that existing 2D and 3D switches, need to make post mirror film on an ito substrate, and requirement can bear follow-up processing technology.At present, make post mirror film, the technique of employing is all to print coating UV glue in PET film, and then ultra-violet curing Cheng Zhujing film under special dies, post mirror film adds alignment film again.Principal ingredient due to alignment film is polyimide, after coating, needs heating to vapor away organic solvent, heating condition is 120 DEG C/20min, because the heatproof of PET film is lower than 100 DEG C, after heating, there will be warpage and contraction, cause diaphragm deformation, final reduction 3D display effect.
Summary of the invention
for above-mentioned technical matters, the invention provides the situation such as membrane structure warpage and contraction that a kind of production and processing there will not be, improve final 3D display effect.
concrete technical scheme is:
for the liquid crystal cell that 2D and 3D switches, comprise the first half and Lower Half, the described first half comprises substrate, and the lower surface of upper substrate is covered with indium tin oxide conductive film, the lower surface of upper indium tin oxide conductive film has post mirror film; Described Lower Half comprises lower substrate, and lower upper surface of substrate is with lower indium tin oxide conductive film, and lower indium tin oxide conductive film upper surface is with alignment film; The first half and Lower Half are linked together by frame glue; Space perfusion liquid crystal between described post mirror film and alignment film.
for the liquid crystal cell that 2D and 3D switches, preparation method comprises the following steps:
(1) be covered in substrate at upper indium tin oxide conductive film, upper indium tin oxide conductive film be coated with the alignment film material of one deck, the refractive index of alignment film material is equal with the refractive index ne of liquid crystal; Prebake conditions, removes solvent;
(2) mould is pressed in alignment film material, by the mode preformed of type of heating or ultra-violet curing, then toasts sizing and make post mirror film; Carry out mechanical friction orientation again;
(3) exposure technology is utilized to form lower indium tin oxide conductive film in lower substrate;
(4) indium tin oxide conductive film coating alignment film under, then mechanical attrition method carries out orientation;
(5) be coated with frame glue in the Lower Half surrounding of liquid crystal cell and beat silver paste points, the Lower Half of liquid crystal cell and the first half are to group laminating;
(6) perfusion liquid crystal is carried out between post mirror film and alignment film;
(7) pressing of flexible circuit board and FFC is carried out.
liquid crystal cell and preparation method thereof switched for 2D and 3D provided by the invention, technique preparation is simple, avoids post mirror film adding the diaphragm occurred man-hour to shrink and the factor such as distortion, effectively improves 3D display effect.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
Embodiment
accompanying drawings the specific embodiment of the present invention.
as shown in Figure 1, for the liquid crystal cell that 2D and 3D switches, comprise the first half and Lower Half, the described first half comprises substrate 1, and the lower surface of upper substrate 1 is covered with indium tin oxide conductive film 2, the lower surface of upper indium tin oxide conductive film 2 has post mirror film 3; Described Lower Half comprises lower substrate 8, and lower substrate 8 upper surface is with lower indium tin oxide conductive film 7, and lower indium tin oxide conductive film 7 upper surface is with alignment film 6; The first half and Lower Half are linked together by frame glue 4; Space perfusion liquid crystal 5 between described post mirror film 3 and alignment film 6.
for the liquid crystal cell that 2D and 3D switches, preparation method comprises the following steps:
