IP into the LED screen export power, small market prospects look good

LED display market in 2015 with a small spacing, high quality products marked by the market, the market outlook is showing significant growth, the hottest is the Chinese market. Other Southeast Asia, Northeast Asia, North America, Europe, the Middle East and the 2016 Olympic Games in Brazil, South America and other markets, small spacing LED display market is also quickly open. LEDinside interviews with LED chips at home and abroad and related vendors to provide the latest market intelligence and trend analysis.

At present the LED display (LED billboard, LEDDisplay) is divided into indoor and outdoor screen screen, the main buyers of commercial space for public space operators, advertising films, advertising posters carousel. In the past, the field of products to low order LED products, LED spacing between relatively large, with the size of the face of the resolution is relatively low, the use of LED is also relatively small. But thanks to the LED chip and packaging technology, can reduce the present surface with LED spacing, small pitch LED display with higher resolution, as long as the audience have compared with the watch, can feel quite obvious is qualitative progress, there are more and more high order single buyer market.

Small spacing LED market in just three years to get the rapid growth of the market have major manufacturers Chinese Riyadh, Chau Ming photoelectric and so on, on behalf of the Taiwan manufacturers is billion light, Wang Qi and so on, these LED vendors work in the global LED display achievements in the field of international companies including Barco and obvious to people, Daktronics, etc. that itself is on the stage, theatres, stadiums, public and commercial space, LED display manufacturers in recent years also cut small pitch LED display market, driven by the wave of new business opportunities.

The greatest benefit? Substantial increase in orders after the main benefit

LED package using LED display, each pixel (pixel) reduced from 3 lamp to 3535, 3030 and three dimensions (3-in-1) specifications, one pixel size has continued to shrink. As a result, the LED display of the same size, the number of the LED particles can be greatly increased, along with the field of boost LED chip shipments to grow.

For the past few years LED mature technology, improve the luminous efficiency, so the brightness of the LED wafer more bright, past outdoor LED display because the LED chip is not bright enough, with the 20mA drive current of single module, now as long as the 10mA or even lower current, the overall power is up to half.

In the outdoor LED display market, the past commercial space owners, not willing to buy high quality LED display, or larger size LED display is the main reason for the amount of power consumption. If the actuarial, the new specification of the LED display power consumption is low, the creation of advertising revenue is better, manufacturers purchase orders will increase, bring more orders.

Shi Honghui, director of the Taiwan LED epitaxial crystal crystal is responsible for the RGBLED display products, said LED energy saving screen because of reduced power consumption, can attract more buyers. For example, in the early stage of the market in order to help the LED display screen cooling, so to use more electric fans to help heat, not only caused by thick and heavy perception, but also consumes more power consumption. And now the new LED display, due to the use of energy-saving design, the cooling effect is better, not only greatly reduce the power consumption of the entire screen, but also save the entire screen layout cost, design more simple and flexible, thickness, weight, more can save transportation and installation cost of manpower. This type of energy-saving products are also subject to the indirect support of the government's case, the benefits are positive.

Indoor LED display market is also showing a similar trend - the brightness of the new technology to improve the drive current can be reduced. In this field, the former mainstream LED package size is 3528, 2121, 2020 are now being replaced, from further reduced, so the number of LED particles per unit area increased use of each point is less than 2.5mm, high P1.9, P1.6 specifications have been can be done, and no spell visual defect seam. If the driver with a good IC, color and surface performance can be better. With the positive impact of the evolution of specifications, the market is also very fond of such small spacing LED to create a high quality display screen, zoned clear, more used in shopping malls, shopping malls and other indoor commercial space.

Future trends in LED chips for display applications

Small spacing LED display at this stage of the market share of about 10%, is rapidly rising. The future trend of the market will be:

1, smaller size LED

1010, 0909, 0808 these relatively small size is relatively easy to do with small spacing LED. Existing 0808LED package, has been able to achieve a small spacing P1.2 LED display products. The smaller size, such as 0505, 0606 of this LED package is more expensive, the cost is mainly from the cutting test and picking.

2, the commercialization of ultra-high resolution products

The higher resolution of the product for some high-end commercial advertisers are attractive, so the high quality of the 2K specification LED display is particularly popular in the high-end market models. The future if the market has 4K specifications of LED display screen, related costs are more mature, the P0.8 will be the standard spacing in addition to war room applications, high order commercial space star, need longer time to have the opportunity to see commercial achievements.

The future direction of the development of technology, LED chip size to shrink to how small it? In the existing LED package, such as 0505, 0404, is the limit of the current commercial packaging size, only higher quality, such as the aforementioned 4K, 8K
