The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
The first specific implementation way is as follows: the following describes the present embodiment with reference to fig. 1 to 14, and the 3D display method of the large-size liquid crystal tiled display screen in the present embodiment includes the following steps:
s1, preparing 1/4 phase difference layers on the backing film 200, wherein the 1/4 phase difference layers are formed by alternately arranging 1/4 phase difference layers 103 in the first direction and 1/4 phase difference layers 104 in the second direction in an equal width mode;
the process of preparing 1/4 phase difference layer in step S1 is as follows:
s1-1, coating a birefringent material on the bottom supporting film 200, and drying and evaporating to form a thin film layer;
the birefringent material is preferably a liquid crystal material, and the thickness of the material is 1 mu m;
s1-2, photo-aligning the surface thin film layer so that one part has 1/4 phase difference layer 103 of the first direction and the other part has 1/4 phase difference layer 104 of the second direction;
the phase difference in the first and second directions are completely opposite, and the phase difference between the 1/4 retardation layer 103 in the first direction and the 1/4 retardation layer 104 in the second direction is 90 °.
The carrier film is provided with a recognizable cutting icon.
S2, splicing the plurality of carrier films 200 with 1/4 phase difference layers prepared in the step S1 into an a x b matrix,
s3, attaching the anti-dazzle layer 301 to the phase difference layer side of the matrix through glue, wherein the anti-dazzle layer 301 is provided with a substrate 300;
s4, peeling off the carrier film 200;
s5, the base film is peeled off and then is aligned and bonded with the liquid crystal splicing screen 400 and cured, and the phase difference layer is bonded with the linear polarization layer side of the liquid crystal splicing screen 400, specifically:
the liquid crystal spliced screen 400 controls sub-pixels to be effective in an interlaced or alternate mode, the sub-pixels in the other half are ineffective, the 1/4 phase difference layer 103 in the first direction and the 1/4 phase difference layer 104 in the second direction respectively and oppositely cover two adjacent rows or two adjacent columns of effective sub-pixels, and the span of the 1/4 phase difference layer 103 in the first direction is from the central line of one row or column ineffective sub-pixels to the central line of the adjacent row or column ineffective sub-pixels;
s6, peeling off the substrate 300 of the antiglare layer 301;
s7, cutting off redundant phase difference layers and anti-dazzle layers 301 along the edge of the liquid crystal spliced screen 400 to form a 3D display liquid crystal screen unit;
and S8, splicing the plurality of 3D display liquid crystal screen units into a matrix to form a large-size liquid crystal spliced screen.
Due to the technical limitation, the phase difference layer of the array is formed on the bottom supporting film 200, the dot pitch can be more than 1.2mm at present, the width can be less than 500mm, and the requirements of large-size splicing of the spliced screen and small-pitch splicing of the spliced screen cannot be met. According to the embodiment, the plurality of 3D display liquid crystal screen units are prepared, and then the plurality of 3D display liquid crystal screen units are spliced into the matrix to form the large-size liquid crystal spliced screen, so that the defects of the prior art are overcome.
For example, the 3D display lcd panel unit comprises a liquid crystal tiled panel 400 and 1/4 retardation layers thereon (the 1/4 retardation layer is composed of 1/4 retardation layers 103 in the first direction and 1/4 retardation layers 104 in the second direction, which are alternately arranged with equal width), and an anti-glare layer 301, wherein the liquid crystal tiled panel 400 is formed by assembling a × b 2 × 2 liquid crystal panels 100 (see fig. 2), a 1/4 retardation layer is prepared on the bottom supporting film 200 according to step S1, the 1/4 retardation layer is larger than the liquid crystal tiled panel 400 (see fig. 4), for the purpose of subsequently cutting 1/4 retardation layers to align with the liquid crystal tiled panel 400 (see fig. 6), after the 3D display lcd panel unit is prepared according to steps S1 to S7, a plurality of 3D display lcd panel units are tiled to form a large-sized liquid crystal tiled panel, referring to fig. 7, the large-sized lcd panel is formed by combining 4 lcd panel units for 3D display, where m × n is 4 × 4 lcd panels 100, m is 4 is an integer multiple of a equal to 2, and n is 4 is an integer multiple of b equal to 2.
When the large-size liquid crystal spliced screen is used in 3D, pixel interlacing or alternate row pixels are controlled to be halved, and when interlacing is adopted, the line output resolution is halved, as shown in figure 1; with alternate columns, the column output resolution is halved as shown in FIG. 2. The pitch width of the 1/4 phase difference layer is 4 times of that of a row pixel or a column pixel of the liquid crystal spliced screen.
Referring to fig. 14, an image output by the liquid crystal tiled display 400 outputs linearly polarized light through the linear polarization layer on the light exit side of the image, outputs alternately arranged left-handed and right-handed optical rotations through the 1/4 phase difference layers 103 and 104, and a viewer can view a 3D image by wearing 3D glasses. If the 2D image is watched, only a 2D film source needs to be played and the image can be watched by naked eyes, and the resolution loss is half.
The liquid crystal panel itself has high resolution, and if matching with the high resolution, the widths of the effective row/column and the ineffective row/column of the 1/4 phase difference layers 103 and 104 are extremely small, and the widths are too small to be suitable for 3D display.
According to the liquid crystal display, the 1/4 phase difference layer 103 in the first direction and the 1/4 phase difference layer 104 in the second direction, which are completely opposite in phase difference, are applied to 3D display of the liquid crystal screen at the expense of resolution, firstly, the resolution of the liquid crystal screen is high enough, the output image quality is still higher than that of an LED display effect even if half of the output image quality is sacrificed, granular sensation is completely avoided, and secondly, 2D display is not influenced after the 1/4 phase difference layers 103 and 104 are applied, so that the purposes of large screen, compatibility with 2D and 3D display and low cost are achieved.
When 2D is displayed, 1/4 the phase difference layers 103 and 104 do not carry out 3D processing, and simultaneously the pixels of the liquid crystal screen are kept as they are and are not halved, so that the 2D display effect is kept unchanged; when 3D is displayed, the horizontal or vertical sub-pixels of the pixel are reduced by half, and 3D viewing is realized by wearing 3D glasses and matching 1/4 phase difference layers 103 and 104.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims. It should be understood that features described in different dependent claims and herein may be combined in ways different from those described in the original claims. It is also to be understood that features described in connection with individual embodiments may be used in other described embodiments.
