Why are small-spacing LED displays becoming more popular?


LED display is a well-developed product in China. From the beginning, it mainly displays text content, and then to the later graphic and dynamic video, it is widely used in indoor and outdoor large-scale advertisements, stage performances, exhibitions, sports events, hotel lobbies and other occasions.LED screen has the advantages of large display area, high brightness, bright color, easy assembly, high utilization rate of building space and low maintenance cost.However, due to technical bottlenecks such as large pixel spacing of LED display and strong grain sense when viewed at close range, it failed to enter the middle and high-end indoor mainstream applications.In recent years, with the development of technology and the increasingly mature semiconductor manufacturing process, LED display point spacing is getting smaller and smaller, and the resolution is getting higher and higher.

Among the large screen display, small spacing LED to win the secret weapon of the market

For a long time, splicing gap is an important factor to influence visual perception, DLP splicing, liquid crystal splicing and PDP splicing due to physical properties, flat-fell seam is more or less, the development of the technology can only shrink flat-fell seam, but can't make it disappear: projection splicing although physically seamless, but existing fusion zone, it is test manufacturer's technical strength, and regular adjustment is needed to guarantee the effect of blend.And LED display with the characteristics of seamless splicing, there is a large plasticity in splicing.At the same time, the small-spacing LED has a better consistency effect, and the mature point-by-point correction technology makes the adjustment process simple and easy to maintain.

For small-spacing LEDs, the industry's acceptance is almost one-sided.And small-spacing LEDs, by virtue of their own technical advantages, begin to have the possibility to impact the existing competitive landscape and enter the middle and high-end applications.Small pitch and high density LED display (P2.5 and below) made a strong invasion into AV engineering field in 2013, and became a new force of large screen display, just like large screen display of high brightness project projector, DLP, PDP and LCD splicing screen.For customers, the high brightness of LED with small spacing, no patching, small installation space and other aspects are attractive to them. The proportion of customers' active requirements is on the rise. In 2013, as for the display screen of large halls, more than 80% of customers will require the LED screen as one of the options for selection comparison;Monitoring and production scheduling command center will be more cautious, about 30 percent of customers will consult the feasibility of using LED large screen scheme.

Small spacing LED has a wide range of applications and impacts the high-end application market

Small spacing products are mainly for TV studios, power system monitoring center, space command center, military command center, government affairs hall, city monitoring center, video conference room, dispatching room, airport, railway station, media and large and medium-sized enterprises and other places.

The goal of small-spacing LED manufacturers is very clear, gradually from the high-end application market to expand the brand influence, and eventually large-scale application to the commercial market.The strategic route of relevant manufacturers is also very clear: first, occupy part of the replacement of DLP rear projection and LCD splicing wall display products;The second is the screen display in public places such as airports, shopping malls and hotels, especially in conference rooms.The main markets of small-spacing LED products are high-end command and control, monitoring room, conference room and other fields, which are exactly the main markets for traditional large-screen splicing products, especially DLP, which have been deeply roots and carefully developed for many years.

The ultimate goal, of course, is to break the dominance of DLP, PDP and LCD and reshuffle the entire large-screen market.This goal is not beyond our reach, not to mention the advantages of small-spacing LEDs such as non-patchwork, easy maintenance and high brightness, and the small-spacing LED technology is already at the forefront of the market for domestic manufacturers.

Easy implementation of 3D/4K

The spacing of LED screens is getting smaller and the resolution is getting higher and higher, which enriches and expands the functions and application fields of screens, from outdoor to indoor, from billboards to television sets.In this process, the screen performance is also constantly improving, not only requires higher color, brightness, contrast, 4K, 3D and other concepts are indispensable.

At the 2010 World Cup in South Africa, 3D high-definition LED screens were introduced to the public.At the World Cup Fan Festival in Saitama, Japan, what was billed as the world's largest 3D LED screen at the time was on display, measuring 867 inches, 19.2 meters wide, 10.8 meters high, with a pixel pitch of 4.44mm. A total of 13,200 people wore 3D glasses to watch the live 3D World Cup.

Compared with other 3D screens, 3D LED screens have higher brightness, brighter colors, higher contrast, ultra-thin and lightweight, and have a natural and comfortable field of vision and a wider viewing Angle. It has a great prospect in many specific places.Today, small screen spacing and 3D technology allow for better display, and the development of glasses-free 3D technology opens up even greater potential for 3D LEDs.Compared to 3D, the 1.2mm pixel pitch, 104 inches to achieve HD, 208 inches to achieve 4K.

3D+4K+ small spacing, so that LED display can be on a par with the projection, flat panel display, DLP back projection, or even replace the latter call is also increasingly high.
