Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.
The application is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
The first embodiment is as follows: next, a 3D display method of a large-sized liquid crystal display panel according to the present embodiment will be described with reference to fig. 1 to 14, where the method includes the following steps:
s1, preparing a 1/4 phase difference layer on a backing film 200, wherein the 1/4 phase difference layer is formed by 1/4 phase difference layers 103 in a first direction and 1/4 phase difference layers 104 in a second direction in equal width alternation;
the process for preparing the 1/4 phase difference layer in the step S1 is as follows:
s1-1, coating a birefringent material on a backing film 200, and drying and evaporating to form a film layer;
the birefringent material is preferably a liquid crystal material, and the thickness of the material is 1 mu m;
s1-2, photo-orienting the surface film layer so that one part of the surface film layer has a 1/4 phase difference layer 103 in a first direction and the other part of the surface film layer has a 1/4 phase difference layer 104 in a second direction;
the phase differences in the two directions of the first and second directions are completely opposite, and the phase difference between the 1/4 phase difference layer 103 in the first direction and the 1/4 phase difference layer 104 in the second direction is 90 °.
The carrier film is provided with identifiable cutting icons.
S2, splicing the plurality of backing films 200 with the 1/4 phase difference layers prepared in the step S1 into an a multiplied by b matrix,
s3, attaching the phase difference layer side of the matrix to an anti-dazzle layer 301 through glue, wherein the anti-dazzle layer 301 is provided with a substrate 300;
s4, stripping the backing film 200;
s5, the backing film is peeled off and then is aligned, bonded and cured with the liquid crystal spliced screen 400, and the phase difference layer is bonded with the linear polarization layer side of the liquid crystal spliced screen 400, specifically:
the liquid crystal spliced screen 400 controls the effective sub-pixels in an interlaced or spaced mode, the other half of the sub-pixels 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 are respectively opposite to cover the effective sub-pixels in two adjacent rows or two adjacent columns, and the span of the 1/4 phase difference layer 103 in the first direction is from the central line of the ineffective sub-pixels in one row or column to the central line of the ineffective sub-pixels in the adjacent row or column;
s6, stripping the substrate 300 of the anti-dazzle layer 301;
s7, cutting off redundant phase difference layers and anti-dazzle layers 301 along the edges of the liquid crystal spliced screen 400 to form a 3D display liquid crystal screen unit;
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 limitation of the technology, the phase difference layer of the array is formed on the backing film 200, so that the point distance is more than 1.2mm, the width is less than 500mm, and the requirements of large-size splicing of the spliced screen and small spacing of the spliced screen cannot be met. In the embodiment, a plurality of 3D display liquid crystal screen units are prepared first, and then the plurality of 3D display liquid crystal screen units are spliced into a matrix to form a large-size liquid crystal spliced screen, so that the defects of the prior art are overcome.
For example, the 3D display panel unit is composed of a liquid crystal panel 400 and 1/4 phase difference layers thereon (the 1/4 phase difference layers are composed of 1/4 phase difference layers 103 in the first direction and 1/4 phase difference layers 104 in the second direction with equal widths alternately), and an antiglare layer 301, wherein the liquid crystal panel 400 is composed of a×b=2×2 liquid crystal panels 100 (see fig. 2), the 1/4 phase difference layers are prepared on the backing film 200 according to step S1, the size of the 1/4 phase difference layers is larger than that of the liquid crystal panel 400 (see fig. 4), the purpose is to make the 1/4 phase difference layers fit and align with the liquid crystal panel 400 (see fig. 6) in order to cut the 1/4 phase difference layers later, and then splice the plurality of 3D display panel units to form a large-size liquid crystal panel after the 3D display panel unit is prepared according to steps S1 to S7, the large-size liquid crystal panel is composed of m×n=4×4 liquid crystal panels 100, m=4 is an integer multiple of a=2, n=4 is an integer multiple of the large-size liquid crystal panel unit is formed by splicing the large-size of the liquid crystal panel unit in fig. 7.
The large-size liquid crystal spliced screen controls pixel interlacing or column spacing pixels to be halved when in 3D use, and line output resolution is halved when the column spacing is adopted, as shown in figure 1; with the columns apart, 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 the row pixels or the column pixels of the liquid crystal spliced screen.
Referring to fig. 14, an image output by the liquid crystal spliced screen 400 outputs linearly polarized light through a linear polarization layer at the light-emitting side thereof, and outputs alternately arranged left-handed and right-handed optical rotations through 1/4 phase difference layers 103 and 104, so that a viewer can watch a 3D image by wearing 3D glasses. If the 2D image is watched, only the 2D film source is needed to be played and watched by naked eyes, and the resolution is lost by half.
The resolution of the lcd itself is high, and if the resolution is matched to the high resolution, the effective row/column and ineffective row/column widths of the 1/4 retardation layers 103 and 104 are very small, and too small a width is not suitable for 3D display.
The application applies the 1/4 phase difference layer 103 in the first direction and the 1/4 phase difference layer 104 in the second direction with the phase difference completely opposite to each other to the 3D display of the liquid crystal screen at the cost of resolution, firstly, because the liquid crystal screen is high enough in resolution, even if half of the liquid crystal screen is sacrificed, the output image quality is still higher than the LED display effect, no granular feel is caused, and secondly, the 2D display is not affected after the 1/4 phase difference layers 103 and 104 are applied, so that the purposes of large screen, compatibility of 2D and 3D display and low cost are achieved.
When displaying 2D, the 1/4 phase difference layers 103 and 104 do not perform 3D processing, and meanwhile, the pixels of the liquid crystal screen are kept unchanged and are not halved, so that the 2D display effect is kept unchanged; when the 3D is displayed, the horizontal or vertical sub-pixels of the pixels are reduced by half, and 3D viewing is realized by wearing 3D glasses and matching with 1/4 phase difference layers 103 and 104.
Although the application 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 application. 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 application as defined by the appended claims. It should be understood that the different dependent claims and the features described herein may be combined in ways other than as described in the original claims. It is also to be understood that features described in connection with separate embodiments may be used in other described embodiments.
