Seamless splicing screen
The development of large-screen seamless splicing technology has experienced three stages: pure hardware fusion technology, pure software fusion technology and software and hardware fusion technology.
Pure hardware fusion technology fuses images through optical shading processing. Pure software fusion technology completes image fusion through electronic circuit processing. Software and hardware fusion technology refers to both optical shading fusion processing and electronic fusion processing.
Since the hardware fusion can better deal with the black balance of the fused image, and the software fusion can better deal with the white balance of the image, the combination of the two software and hardware fusion technologies can perfectly realize the true reproduction of the fused partial color image.
From the perspective of large-screen splicing, seamless splicing technology has also experienced three stages of development: hard-edge splicing, overlapping splicing, and soft-edge splicing.
The hard edge splicing has obvious dividing lines (that is, physical seams), and the integrated display of the panorama cannot be realized; the overlapping splicing refers to overlapping the images thrown by the two projectors in a superimposed manner at the merging, but the splicing obviously exists. The disadvantage of the over-bright area due to the superposition of brightness is affected by the flattening, which affects the realization of the seamless effect.
The soft edge fusion splicing process achieves the complete fusion of the two sides through the edge fusion technology, and eliminates the over-bright areas caused by the overlapping splicing, and the soft-edge fusion splicing can adapt to the splicing of various surface shapes such as plane, cylinder and sphere. , has a wider range of applicability. Whether the soft edge fusion splicing technology is currently the mainstream technology is also the future development direction.
The soft edge fusion splicing system is a complex multi-screen splicing system project. Usually, a complete soft edge fusion splicing system is required to meet the following equipment.
1. Screen: The most intuitive visual impact on the screen for the viewer, the choice of screen is crucial. First make sure that the screen is seamless and seamless to ensure the perfect display of the picture. The American view Stewart is an active advocate of large seamless screen and soft-edge fusion stitching. The domestic metal screens such as Aulong and Baoshi are also good.
2. Projector: The picture quality of the projector directly affects the display effect of the large screen. It is also very important to be sloppy. A projector with 3-DMD technology is used as much as possible to ensure good color reproduction. High-end 3-LCD projectors can also be used, but it takes a lot of time to adjust the color consistency.
3. Soft edge fusion splicing processor: The soft edge fusion splicing processor mainly determines the content and speed of the large screen display, the quality of the processor, the processing speed of the signal source, the clarity of the picture, the quality of the soft edge fusion, There is a role that cannot be underestimated.
4. Signal processing equipment: Signal processing equipment includes signal source type conversion, signal switching, signal amplification and transmission, etc., which is very important for large screen display.
5. Centralized control equipment: The large-screen video wall display system has a wide variety of devices. The number of projectors, the number of matrices, and the number of signal sources are relatively large. Central centralized control devices can help you quickly process signal selection and switching. It is convenient and quick to control the operation process of the equipment, and quickly improve work efficiency and accuracy.
6. Peripherals: Peripherals include signal source desktop access systems, cables, connectors, cabinets, power supplies, and more.
Mall application case analysis
Large supermarkets, department stores, specialty stores and other large venues often have some discounts, activities and other information. LCD screens with its large screen, full HD and other advantages can make these exciting information stand out in any place and space. Displayed to each patronized customer to promote consumption; at the same time, narrow-edge, ultra-narrow, seamless large-screen LCD splicing system can also be advertised in the above large-scale venues, so that the picture is vivid, bright and delicate display Even in busy shopping malls, you can stand out from the noisy environment, grasp the attention of new customers and bring more new business opportunities!
LCD splicing screen application analysis:
1, large, high-definition LCD video wall can be a perfect display of all shopping mall products, no matter which region, space, angle can be very attractive to attract consumers to eye, convenient for users to shop;
2, play product discounts, activities and other information to attract more users to spend, thus bringing more benefits to the mall;
3, the mall has a large flow of people, can play business products, or corporate advertising with its excellent, perfect picture, bringing additional advertising benefits to the mall.
LCD splicing screen function introduction
The large screen splicer is used under the Windows XP operating system to provide a high-resolution Windows graphics display environment, which can extend the windows desktop to up to 64 displays. The structure of the multi-screen system may be arranged in any rectangular form. The system effectively superimposes the resolution of a single display for greater picture size and greater image resolution.
The large screen system is specially optimized for LCD splicing. It will present the most outstanding DID high definition, high brightness and high color gamut liquid crystal display technology, embedded hardware splicing technology, multi-screen image processing technology, signal switching technology, etc. Together, it forms an advanced LCD screen display system with high brightness, high definition, low power consumption and high life. All input signals can be displayed freely in the display wall window, fully supporting image display functions such as cross-screen, roaming, picture-in-picture, overlay, zoom, etc.
