Supply Changchun monitor 46-inch LCD video screen display monitor video wall

With the development of liquid crystal display technology, embedded hardware-splicing techniques, multi-screen image processing, signal switching technology video wall related technology, the new mosaic wall equipment rapid spread in the end the big screen display engineering applications, especially embedded LCD mosaic wall, although the market is not long, but it has been widely welcomed. LCD mosaic wall as a safe city command center, Railway (MTR), ports, terminals surveillance systems, intelligent traffic management control center, defense or military surveillance systems, power control and supervision system, large factories, mines monitoring systems, financial management and monitoring systems, television or large Studio Center monitor walls, large venues background walls, video conferencing and other information collection, processing key display device having various types of computer analog / digital signals, a composite video signal, the color difference signals on the big screen, and to achieve signal switching, stacking and combination of functions. Liquid crystal (LCD) projection mosaic wall is different from (DLP) TV wall, high-tech mosaic wall plasma (PDP) TV wall, the paper describes the specific technical advantages of its implementation, and are illustrated by specific examples. I. Overview of mosaic wall is known, is currently in the field of large-screen display splicing manufacturers and a variety of technologies can be described as flourishing, the leading position, but in the final analysis, it can be divided into three major technique in which, on the liquid crystal mosaic wall a development advantage. 1, the principle of rear projection mosaic wall DLP technology is very simple, set a projector inside rear projection unit, issued after the image projected onto the back of the screen zoom lens by lens reflex, that projection. DLP mosaic wall itself classification of many, various terms after another, but summed up, its prominent feature is the large unit size, technology is relatively mature, the seam is small; its main drawback bulky, short life, the picture quality is not high . 2, plasma walls PDP plasma display as the home for the motion picture, due to the early use of high brightness, high contrast, high color gamut, wide viewing angle and other characteristics by many users, but applied to the field of security, or need long When the time display still images or graphics, for example, to make a monitor or a TV mosaic wall, there is a serious flaw: display a static image blur even prone to burn-in, the so-called plasma brand, brightness decay rapidly, Once after the mark or brightness down unrecoverable; low reliability, power consumption is high compared to other technologies. Currently, there specifically for stitching 42 "; screen market, (which borders interval of about 5mm), but the price is more expensive at the current level of technology, PDP can not overcome the disadvantages of a serious impediment to its large-screen display in the commercial market. Applications. 3, a liquid crystal mosaic wall LCD is the most high-end, the best display device, and its excellent performance has been widely recognized. LCD mosaic wall using the LCD screen as the stitching unit, to overcome the disadvantages of DLP and PDP walls provide An excellent performance, flexible mosaic wall. Of course, due to the current backlight LCD products luminous still use cathode tubes (CCFL), filament and across the lamp socket which limits the size of the liquid crystal panel, the current screen to fight As used DID LCD screen still frame of 11mm width, so the seam is slightly disadvantage of liquid crystal mosaic wall, but with inputs LED backlight technology, this defect will be significantly improved. Second, the LCD splicing curtain wall technology LCD products relative to DLP products, PDP product advantages in the use of effects, technical parameters, and is already well-known fact, do not say. Now I focus on to talk about two major advantages in the field of large-screen display has 1 , a combination of sizes, more flexible LCD various size range, the size of random .LCD mosaic wall, in addition to the number of arbitrary choice splicing [line (m) × column (n)], the screen size also have a variety of options, and can be mixed stitching, which meet the needs of different places, and we know, mosaic wall in addition to bring the whole screen large screen display, but also to achieve multiple small screen. For example mosaic wall, a traffic control center, more often required to achieve all monitoring points while viewing the screen, when a monitoring point appears abnormal situation, you can quickly zoom to full screen for the monitoring center all at the same view. This requires practice, mosaic wall in both the big picture and small picture should achieve a good display. DLP rear projection and PDP plasma splicing wall, its cell size large size, some up to 100 inches or 150 inches, which is certainly the big picture when displaying certain procedures to reduce the seam, but because lower resolution, if Quad, achieve multiple screen display purposes, the effect is far from ideal, but due to increased equipment costs and the stability of the system have caused a great impact. As a result, DLP mosaic wall can only be used to display a large screen, while the number of monitoring points still need to use a small screen LCD monitor or other display monitors, signal switching frequency, the effect is far from ideal. LCD mosaic wall, there is no such problem. We know relatively liquid crystal display unit, the size is relatively small, but the resolution is the highest, and sizes can be mixed splicing, which facilitates the user according to the actual needs and reasonable arrangements for splicing programs reach the size fit , the effect should be all-win. All along, LCD, although there are many traditional advantages, but because of its "huge" gap, resulting in front DLP LCD always suppressed, but this year, a breakthrough in LCD technology has a patchwork quality Does that mean there will be a large LCD screen to field some circumstances it? With the large-screen display wall screen, widely used in business applications, splicing technology market has become increasingly broad, unlimited potential in this industry, DLP technology has been a dominant gesture occupy display market, but at the same time, the sudden emergence The LCD video splicing technology has not be ignored, it is growing at a rate fast Meng seize the display market. What is the reason to make such a rapid rise LCD stitching, let us go to explore it. LCD splicing wall can be used both small-screen, large-screen can also be used; either one single-screen display to be a pair of M × N entire screen display; the size of the screen can also mix assembly. LCD mosaic wall, can cater for different customer needs, create a personalized system, provide different embodiments and technical support. This has the selection method of stretching space, it should be an important customer to choose his reasons for it. LCD splicing wall with high reliability DID LCD screen, 40 "and weighs only 12.5KG, power 200W, liquid crystal display principle unique, all-digital drive system, and an air vortex cooling method uses fluid mechanics designed to ensure that the high reliability and stability curtain, while steel curtain wall frame and reasonable process design, equipment neither radiation are not subject to external electromagnetic interference, stable and reliable with respect to the DLP and PDP, LCD's life is very long, and heat a small, low failure rate .PDP plasma is easy to produce plasma brand, its dynamic display of life may be up to tens of thousands of hours, but in the high-brightness display static images, it will be possible five thousand hours A screen appears burns; and DLP lamp life only 3000-5000 hours, therefore, recommended to 24 hours of continuous use of security monitoring large-screen mosaic wall of choice, we should try to consider the choice of LCD mosaic wall, in order to improve efficiency and reduce the cost and maintenance cost. Overall, the functional LCD display flat panel display technology thriving, its thinness, light weight, excellent performance of low-power, long life, no radiation, etc. as well as the key performance indicators has made it into the mainstream of development, prospects. Price-wise system of economic considerations, to mention cost, only in high-performance, high-quality premise, the economy makes sense system. LCD display big screen display system, with its excellent performance and reasonable price at home and abroad has been widely welcomed. But why such a prominent advantages in the field of large-screen display now also do not really beat DLP technology, LCD biggest disadvantage in this when also exposed, splicing gap compared to DLP3MM about, LCD splicing technology has been at a distinct disadvantage in this field, but the second half of this year, Samsung SDI led DID panel mosaic display screen to achieve a minimum overall bilateral stitching seams of 6.7 mm LCD splicing unit joint technical indicators than the previous generation increased by more than 70 percent. At the same time, production of bilateral LCD splicing products 3 mm thickness of the display unit is also rafts agenda may officially launched in 2010. LCD splicing products pick significantly improved seam technology and expand the use of LCD products, LCD splicing products begun to enter the mainstream market. LCD splicing technology has been in the big-screen industry fast Meng development, after the splicing gap problem-solving, not difficult to see the future of large-screen industry, LCD has a wider set
