splicing screen

A splicing screen is a complete unit of LCD video wall, both individually as a monitor, but also to a large screen LCD splicing use. According to different needs and achieve big variable is also variable small, variety features: a single split-screen display, single-screen alone, any combination of display, full-screen LCD splicing, vertical screen display.

There are both second andhand hand lcd splicing screen and which are easy to clean and require less maintenance. The lcd splicing screen bead is equipped with a built-in lcd splicing screen design, and generally the most common lcd splicing screen type is the second option. However, the lcd splicing screen bead is less convenient to require and has a built-in storagehesive.

Looking at the large-screen splicing system in my country at this stage, many displays still have more splicing seams in their work. For example, the LCD splicing system has too large gaps to meet the needs of users; while plasma and rear projection large-screen splicing systems have more advantages than liquid splicing technology, but in terms of their visual effects, there are still many split line. Even if LCD, DLP, and PDP technologies are used in engineering, they can only reduce the gap, but cannot completely eliminate them. The seamless LED splicing technology can completely solve the problem of screen segmentation and meet the requirements of complete seamlessness.

The use of seamless LED splicing technology can increase the screen resolution in a small area, ensure the quality of the picture, and meet the needs of users for close viewing. Compared with the existing splicing technology, LED physical seamless splicing can realize cross-screen display. For splicing, its level is not the size of the gap, but the question of whether the gap exists.

The application of seamless LED technology will effectively handle the situation where the brightness and chromaticity attenuation of spliced ​​large screens are different. In this technology, point-by-point brightness and chromaticity correction technology is generally used, which ensures the unity of brightness and chromaticity. For example, the application of point control technology creates a platform for users to correct chromaticity and brightness point by point, and to control the pixels of the screen to achieve a high degree of image restoration. This technology has both SMS and E-mail prompt functions, which can let users grasp the status information of the splicing wall in time.

In the project, a larger viewing angle is provided, and the occurrence of light reflection is prevented. When the picture is taken, the state is relatively stable, and it responds to the dynamic display of the picture. The edge of the image is clear and has good dynamic expressiveness, which can accurately and truly restore the image information. Make the video screen delicate and smooth, bring maximum visual enjoyment. In addition, it is particularly pointed out that the brightness uniformity of the LED screen is excellent, and the single-point brightness correction is carried out to make the brightness uniformity of the entire screen tend to the extreme.

The large screen splicing video display wall is a large screen display system composed of a plurality of display units and video processors, and is generally used for a large screen display of one screen and a multi-window display of multiple screens. Therefore, the input video signals are all processed by the video processors and distributed to each display unit, and each display screen can span the boundary of the display unit.

LED display adopts large-scale integrated circuits, which greatly improves the reliability and facilitates debugging and maintenance. All-weather work is fully adapted to various harsh outdoor environments, waterproof, moisture-proof, anti-corrosion, lightning protection, strong overall performance of earthquake resistance, strong luminous brightness, and the display content is clearly visible when the sun is directly on the surface of the screen within the visible distance, and cost-effective.

LCD splicing screen has low power consumption, light weight, and long life (normally work for 50,000 hours), Non-radiation, high definition, high brightness, high color saturation, high contrast, high resolution and a series of high-quality display advantages, which are highly praised and respected by the large-screen market, and are widely used in security, advertising media, Entertainment and culture, command centers, coal mines and many other industries. But its biggest shortcoming is that it cannot be seamlessly spliced, which is a bit of a pity for industry users with very fine display screen requirements.

At present, LCD splicing screens can be spliced ​​arbitrarily according to customer needs, up to 10X10 splicing. And secondly, LCD splicing screens use LED backlight to emit light, with a life span of up to 50,000 hours. The life of the backlight source is ten times that of the rear projection bulb compared to DLP and PDP. In addition to the high definition, high brightness, high color saturation, high contrast, and high resolution of LCD splicing, the life of the LCD is very long. Moreover, the power consumption is low, the heat generation is small, the failure rate is very low, the performance is stable to support 7×24 hours of uninterrupted work, and the subsequent maintenance cost is low.

DLP is the abbreviation of "Digital Light Procession" which means that this technology must first process the image signal digitally, and then project the image with light. It is based on DMD (Digital Micro-Mirror Device) to complete the visual digital information display technology. The cold light emitted by the UHP bulb passes through the condensing lens, homogenizes the light by Rod. And the processed light passes through a color wheel to divide the light into RGB three colors (or more colors such as RGBW), and then divided colors lights project on the DMD chip through lens, and finally reflected through the projection lens to form an image on the projection screen.

The DLP splicing screen is formed by splicing multiple rear projection display panels. Its main feature is the large screen size and small gaps. Although there will be gaps between the display panels, the physical splicing gaps between the panels can be within 0.5mm. However, the DLP splicing screen still has some fatal shortcomings. Because the DLP display uses multiple display panels to splice, the color and brightness will be uneven when the number of splicing screen is reached, and the power consumption is high, and the internal luminous bulb is continuously working after 6000-8000 hours, the brightness will decrease. In order to maintain a better display effect, the light bulb needs to be replaced, so the maintenance cost is very large. In addition, due to the large thickness of the DLP splicing panel, it is necessary to leave enough space on the back, which is also a problem for some environments with relatively small space.

However, with the continuous development of splicing technology, the current DLP splicing panel adopts LED light source, which not only has a major breakthrough in the service life, but also has revolutionary changes in color and power consumption.

PDP is the abbreviation of “Plasma Display Panel”, its working principle is very similar to fluorescent lamp. At present, there are three types of color PDP researched and developed: single substrate type (also known as surface discharge type) AC PDP, double substrate type (also known as counter discharge type) Formula) AC PDP and pulse storage DC PDP. From the perspective of technical principles, since the luminous plasma tubes in the PDP screen are evenly distributed in the plane, the center and the edges of the displayed image are exactly the same without distortion, and a pure plane in the true sense is realized. Since there is no electron beam movement during the display process, no electromagnetic field is needed, so the external electromagnetic field will not interfere with it, and it has good environmental adaptability.

Since the PDP does not require a background light source for light emission, there is no LCD display viewing angle and brightness uniformity problem, and higher brightness and contrast ratio are achieved. The design of the three primary colors sharing the same plasma tube also avoids focusing and convergence problems and can achieve very clear images. Compared with LCD display technology, the larger the screen of the PDP, the higher the depth and fidelity of the image. In addition to the advantages of brightness, contrast, and viewing angle, PDP technology also avoids the response time problems in LCD technology, and these characteristics are the most important factors in dynamic video display. PDP monitors have no scan line scanning, which is completely pixel-to-pixel, so the image is clear and stable without flicker, and will not cause eye fatigue. PDP is also free of X-ray radiation. Because of these two characteristics, PDP can be called a truly green display product.

However, PDP screen products have large pixel gaps, lower reliability performance than other products, higher power consumption, and congenital shortcomings of life. After 5000-7000 hours of use, the screen brightness will decay by half, and it is difficult to operate at an altitude of 2500 meters or more. Its most fatal weakness is that it is easy to burn when displaying computer images or static images for a long time (the so-called burning phenomenon refers to the change of plasma inside the screen when the plasma TV is in a static state for a long time, causing it to fail to work normally. It appears that there will be residual image of the image at a specific position on the screen, and it cannot be removed regardless of changing any source).

LCD splice screen with the functions of high picture-reduction , high brightness display and automatic shadow elimination, greatly improve its visual performance. To adopt the latest 3D digital decoding, image noise reduction and digital image correction technology. LCD offers you the best visual enjoyment.

Splicing display is more and more applied to commercial display, ultra-narrow seams bring perfect picture, display picture is clear and complete after splicing, wide viewing angle, high brightness, no burns, dynamic and extremely eye-catching , widely used in advertising, image display. It can be applied to Shopping malls, jewelry stores, museums, memorials, planning halls, science museums, etc.

LCD splicing screen can be used as a display alone, but also can be spliced into a large screen use. According to the different use requirements, to achieve variable large can also be changed to small hundred big screen function: single screen split display, single screen alone display, any combination of display, full-screen LCD splicing, double splicing LCD screen splicing, vertical screen display, image border optional compensation or masking, support digital signal roaming, scaling stretch, cross-screen display, a variety of display pre-programmed settings and operation, full HD signal real-time processing.

LCD splicing high brightness, high reliability, ultra-narrow edge design, uniform brightness, stable image without flicker, as well as having a longer service life of the LCD splicing screen, etc.

LCD splicing screen is a single independent and complete display unit, ready to hang, installation is as simple as building blocks, single or multiple LCD splicing screen use and installation are very simple. LCD splicing around the edge of only 0.88mm width, the surface with tempered glass protection layer, built-in intelligent temperature control alarm circuit and the unique “fast dissipation” cooling system.

LCD splicing screen has everything, not only adapt to digital signal input, the support of analog signal is also very unique, in addition to the LCD splicing signal interface, the use of DID LCD splicing technology to achieve the analog signal and digital signal can be accessed at the same time, the most recent one LCD splicing technology can also achieve the naked eye 3D intelligent effect. LCD splicing series of products using unique and the world’s most cutting-edge digital processing technology, allowing users to truly experience the full HD large screen effect.

The single screen size of the splicing screen is between 46 and 65 inches. After splicing, it can form a display size of any size. For example, the size of the 3*3 55-inch splicing screen after splicing is about 165 inches, so we can according to the user"s viewing The number of splices can be freely designed for distance and room size to achieve thebestdisplayeffect.

And the touch all-in-one is just a large-size display, it is equivalent to a large tablet computer, the size is between 65~100 inches, can not be spliced, can only be used on asinglescreen.

So relatively speaking, the display screen of the splicing screen can be infinitely large and can be used in large rooms or small rooms, but the number of splicing is different. The single touch screen is only 100 inches in size, which is equivalent tothe size of 4 splicing screens, so it can only be used in small meeting rooms and other occasions. Usually the viewing distance cannot exceed 5 meters, otherwise it will not look Clear the content on the screen.

The splicing screen can realize the simultaneous input and display of multiple computer signals and free layout, so it is particularly suitable for occasions where multiple computers need to be on the screen; at the same time, itsliquidcrystalpanelis an industrial-grade panel, which can be used continuously and the screen is more durable .

The touch all-in-one can only input one computer signal, and the input signal source is relatively single; but it has some other functions that the splicing screen does not have, such as finger touch screen, wireless screen transmission, and two-way control of the computer and touch all-in-one machine. At the same time, the touch one machine also has a writing function, which can be used as a whiteboard. If we have training needs, we can write directly on it.

Although the splicing screen and the touch all-in-one machine belong to the liquid crystaldisplaytechnology, they still have slight differences in the display effect.

For example, the brightness of the splicing screen is higher, the white balance effect is better, and the colors are richer, but there are stitching; the advantage of the touch one machine is that there is no stitching, and the resolution is 4K, and the resolution is higher. Of course, the premise is that Our input signal source is 4K, otherwise even if the screen is 4K, the final display effect is still the same as the resolution of the signal source.

Splicingscreenis mainly used in video surveillance rooms, conference rooms, exhibition halls and other occasions, relatively speaking, the scope of application is wider, and touch one machine can only be used in small conference rooms, training institutions, schools and other occasions.

If we are using it in a meeting room, both the splicing screen and touch one can be selected at this time. Which one to choose depends on the size of the meeting room, the second is the number of input signal sources, and the third is the number of people in the conference. When there are more than 10 people and the meeting room is more than 20 square meters, it is best to use a splicing screen, such as 3*3 splicing. If there is only a small meeting room of 3 to 5 people, you can install a touch all-in-one machine.

The splicing screen is currently divided into curved LCD splicing screen, LCD splicing screen, plasma splicing screen, DLP, transparent screen, etc. At present, it can be used with thesplicingprocessor, central control HDMI matrix, HDMI distributor and other auxiliary materials to achieve the use of the entire system. The latest technology is the HDMI matrix that can be controlled with a “mobile phone.

One touch machine is composed of advanced touch screen, motherboard, memory, hard disk, video card and other electronic components, and it is the same as the working principle of traditional PC. According to the size of the touch screen body and thesoftware, such as public information query, advertising display, media interaction, conference content display, offline experience store product display, etc., such as fingerprint reader, scanner, card reader, micro printer, etc. Designed to meet specific needs such as fingerprint time and attendance, card swiping, and printing. Generally different from the electronic whiteboard, it can realize more functions.
