1. Nowadays, more and more companies are keen on small-pitch LED displays. As a device manufacturer, your company, how do you view the small-pitch LED display market? Can you explain the reasons why companies are keen on small-pitch LED displays from the aspects of market, profit and business?
Shao Pengrui, technical director of Jingtai Optoelectronics:
With the market’s demand for high-quality display and informatization, LED small-pitch display will definitely be the trend of future display development. Let’s first analyze the market: the indoor display screens currently used in the market are mainly projection/DLP/LCD/PDP, and these display products have two common defects:
(1) There are obvious differences in color and brightness after the display is used for a period of time; the consistency of the whole screen is poor, and there is no way to achieve standard resolution, such as the fusion of the overlapping pixels with "eat" in the projection, the patching phenomenon in DLP, the obvious segmentation of the splicing gap in the LCD, etc., which will affect the final display effect.
(2) This type of display is greatly affected by the environment, and the effect of bright light on the display is also seriously affected, and the led small-pitch display can completely solve the above problems.
From the perspective of profit space, the realization of LED small-pitch displays, especially indoor small-pitch displays, must also be tackled technically. The main technical difficulties are breaking through low-brightness, high-gray, higher reliability, and product design and processing accuracy. It can solve this problem together with various supply chains and application manufacturers, which is not only a leap in technology, but also will lead to the real application of small-pitch display technology.
From a business perspective, led small-pitch display has become the hottest term in 2014. Major device manufacturers and application manufacturers have a high degree of attention. From upstream chips to packaging to downstream applications, the entire led industry chain is concerned. From raw material technology/packaging technology/application technology are constantly breaking through. In the future, it will be synonymous with led indoor display.
Ouyang Xiaobo, Deputy General Manager of Nationstar Optoelectronics RGB Device Division:
Small-pitch LED displays have great development potential in high-end fields such as monitoring, command, scheduling, conferences, high-end consumer products, and simulation. In the indoor market, small-pitch LED display products have a large market space in replacing traditional video walls and rear-projection products. The future prospects are good, and we are very optimistic about this market.
From a market perspective, people’s ultimate pursuit of terminal display products is nothing more than two things, one is larger size, and the other is clearer picture quality. The biggest advantage of LED displays is "seamless" splicing, which can theoretically be infinitely spliced, which is very attractive to the display industry. Secondly, compared with traditional LED products, small-pitch LED display products have greatly improved in terms of resolution, refresh rate, gray scale, etc. The display effect and clarity are comparable to commercial large-screen products such as LCD and DLP. At the same time, small-pitch LED displays also have the characteristics of small installation space, simple adjustment, and convenient maintenance, which have won widespread attention in the market.
In terms of profits, because small-pitch LEDs have very high requirements for manufacturers in terms of technology and process, and the high technical threshold directly leads to "the scarcity of things is more valuable", the current profits are quite considerable.
In terms of business, the small-pitch LED display market has huge potential. Some institutions predict that the entire high-density display screen is expected to reach a market increase of 2 billion in 2014. At present, small-pitch LED displays have begun to enter TV stations, high-end conference rooms, high-end consumer goods, simulations and other places, and have achieved certain results. From Nationstar Optoelectronics, we are generally optimistic about the small-pitch LED market and are gradually increasing investment in R&D and marketing. It is expected that sales of small-pitch LEDs in 2014 will increase by about 30% compared with 2013.
Zhang Renhong, Technical Director of RGB Device R&D of Hongqi Technology:
Enterprises and the market are also seeking innovation and change, and it is human nature to pursue beautiful things. In the case of the display screen market, small spacing can greatly improve the resolution of the screen and even lead to LED TV As the level of 4K advances, small-pitch products have opened up another blue ocean for the murderous Red Sea of the display market, allowing the market to pursue higher-level and more detailed displays. At the same time, there is no need to engage in vicious price competition with rivals in the original Red Sea market. The vicious cycle of bad money driving out good money is also unpopular with the industry. Since Hongqi Technology launched 1010 LED for small-pitch use in 2013 Since matte black lamps, they have been highly praised by the industry. This gives friends in the industry who were previously unable to enter the small-pitch market suddenly have another sales tool. It also opens another door for the industry to enter the small-pitch or even micro-pitch market. This can also explain why packaging companies, display manufacturing and even application companies are keen on promoting the small-pitch display market.
