Description
Technical Field
The utility model relates to the field of 3D printing, in particular to a large-size black and white liquid crystal splicing screen for 3D printing.
Background
At present, common high-resolution (not less than 5760 × 3240) and large-size (not less than 13.3 inches) liquid crystal screens are all color liquid crystal display screens. However, in the field of photocuring 3D printing, a black-and-white monochromatic liquid crystal display is required instead of a color liquid crystal display (the color liquid crystal display has high energy consumption and low efficiency, and causes unnecessary waste). The existing black-white monochromatic liquid crystal display screen can usually realize high resolution (pixels are square less than or equal to 50 micrometers), but the sizes of the black-white monochromatic liquid crystal display screen are smaller than 13.3 inches, and a large-size special black-white liquid crystal display screen for 3D printing with the size being greater than or equal to 13.3 inches and the pixels being less than or equal to 50 micrometers cannot be realized. Manufacturers of liquid crystal displays are limited by the total quantity of requirements of 3D screens and the research and development cost of drive ICs, and are reluctant to develop large-size and ultrahigh-resolution black-and-white monochromatic liquid crystal display screens for photocuring 3D printing independently, so that the actual requirements and the production conditions are not equal.
Someone applies the idea of the outdoor or indoor liquid crystal splicing screen to the field of photocuring 3D printing. For example, chinese patent application publication No. CN109968662A describes a light source device and a 3D printing system. In the 3D printing system, the angle between two adjacent sub-screens is adjusted, so that the frames of the sub-screens are prevented from blocking light to form blind areas. However, this approach has the disadvantage that fine adjustment of the angle between the multiple sub-screens is very time consuming, detrimental to the production of the 3D printing system, and the errors remain at the millimeter level, the efficiency or uniformity of the light transmission is reduced.
Subsequently, the inventor of the present application provides a large-size ultrahigh resolution black and white liquid crystal spliced screen for 3D printing in the chinese utility model patent application No. 202121348254.4, which can be spliced into a spliced screen with a size larger than 13.3 inches by using a black and white liquid crystal sub-screen with a resolution higher than 5760 × 3240 and a size smaller than 13.3 inches. However, the width of the isolation insulating tape formed between two adjacent black-and-white liquid crystal sub-screens is 5-15 micrometers, the isolation insulating tape can form a relatively obvious partition line, printing errors and light transmission defects can occur at the partition line, and finally obtained printed products have poor strength at the partition line and are easy to generate printing lines and other defects.
As shown in fig. 1, taking a black-and-white liquid crystal splicing screen 100 ' including four black-and-white liquid crystal sub-screens 101 ' as an example, the arrangement manner of the pixel units 101a ' of the black-and-white liquid crystal sub-screens is completely the same, and the switch circuits 101b ' in the pixel units 101a ' are all located at the same position (the upper right corner as shown in fig. 1), so that a conductive wire has to be led to the isolation insulating tape region during wiring, which is a main reason why the width of the isolation insulating tape cannot be further reduced.
Based on this, the inventor believes that the black-and-white spliced liquid crystal screen still has room for improvement.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the utility model to those skilled in the art.
Example 1
As shown in fig. 2 and 3, the present embodiment provides a black-and-white liquid crystal tiled screen 100 for 3D printing, which includes two black-and-white liquid crystal sub-screens 101 and 102 disposed on the same substrate. The left black-and-white liquid crystal sub-panel 101 has a plurality of pixel cells 101a with switch circuits 101b, and the right black-and-white liquid crystal sub-panel 102 has a plurality of pixel cells 102a with switch circuits 102 b.

Further, two adjacent pixel units 101a and 102a on two sides of the symmetry axis (vertical Y axis) have a first spacing L (i.e. the width of the insulating isolation region) therebetween, and the remaining adjacent pixel units 101a or 102a have a second spacing L therebetween, where the first spacing L is greater than the second spacing L.
Furthermore, the first distance L is increased by 1-2 μm compared with the second distance L. Therefore, the adjacent two pixel units 101a and 102a on two sides of the symmetry axis (vertical Y axis) are effectively prevented from interfering with each other, and the imaging quality of the spliced screen is not affected.
Further, the conductive line connecting the switch circuits 101b, 102b extends perpendicularly to the symmetry axis (vertical Y-axis) to the far side of the symmetry axis. Specifically, the conductive line of the left black-and-white liquid crystal sub-screen 101 connected to the switch circuit 101b extends to the left side perpendicular to the symmetry axis (vertical Y axis) to finally form the interface lead 101c of the left black-and-white liquid crystal sub-screen 101, and the conductive line of the right black-and-white liquid crystal sub-screen 102 connected to the switch circuit 102b extends to the right side perpendicular to the symmetry axis (vertical Y axis) to finally form the interface lead 102c of the right black-and-white liquid crystal sub-screen 102.

The isolation insulating tape is directly manufactured by adopting a mask (also called a lighting board) in the existing liquid crystal display screen manufacturing process, then the processes of gluing, exposure, etching and the like are completed according to the prior art, and finally a frame is arranged for the whole black-and-white liquid crystal spliced screen 100.
Therefore, the black-and-white liquid crystal sub-screens 101 and 102 adopted by the embodiment can be processed to form the black-and-white liquid crystal spliced screen 100 by adopting the existing process, and a driving circuit does not need to be redesigned. When the black-and-white liquid crystal splicing screen 100 is used, a complete picture (namely 1/2 of the complete picture displayed by each black-and-white liquid crystal sub-screen) can be controlled to be displayed by the black-and-white liquid crystal splicing screen 100, and the black-and-white liquid crystal sub-screens 101 and 102 can independently display the complete picture respectively.

The isolation insulating tape is directly manufactured by adopting a mask (also called a lighting board) in the existing liquid crystal display screen manufacturing process, then the processes of gluing, exposure, etching and the like are completed according to the prior art, and finally a frame is arranged for the whole black-and-white liquid crystal spliced screen 400.
Therefore, the black-and-white liquid crystal sub-screens 401, 402, 403 and 404 adopted in the embodiment can be processed to form the black-and-white liquid crystal spliced screen 400 by adopting the existing process, and a driving circuit does not need to be redesigned. When the black-white liquid crystal splicing screen 400 is used, a complete picture (namely 1/4 of the complete picture displayed by each black-white liquid crystal sub-screen) can be controlled to be displayed by the black-white liquid crystal splicing screen 400, and the black-white liquid crystal sub-screens 401, 402, 403 and 404 can independently display the complete picture respectively. Moreover, if the resolutions of the black and white liquid crystal sub-screens 401, 402, 403, and 404 are 5760 × 3240 and 8 inches, the resolution of the spliced black and white liquid crystal spliced screen 300 may be 11520 × 6480, and the size of the spliced black and white liquid crystal spliced screen will exceed 13.3 inches (the pixels may be as fine as 45 microns), so that the requirement of 3D printing on a large-size liquid crystal screen can be met without changing a driving circuit.
