Standardization is very important for an industry's development. However, in the field of LED, there are a few called first class enterprises among state run enterprises, private enterprises, joint ventures and foreign enterprises. We are difficult to find an enterprise has its strength to draft a good standard. For this, GM Cheng Deshi from one Shanghai tech company says, "In the recent case, a good way is to let one enterprise as leader and other several ones participate in. In recent years, several standards in formulation processes prove this viewpoint."
As LED display technologies become increasingly innovated, LED display standard system and relevant contents shall be constantly revised, improved and perfected, so as to adept new changes. Zhang Xiaoguang Senior Engineer when reviewed says, "LED display screen standard system has a certain basis. But there is a long way with heavy tasks for the standardization in the whole industry. Thus, we shall continue hard work to enhance and emphasize on the work of research, formulation, propagation and execution, in order to meet sustainable development needs in the industry."
For LED display standard system construction, Development Manager Yu Jun in a review emphasizes enhancing basic standard construction, forming a systemic-thinking-induced system structure, running market diversification and coming into a more depth.
Worsening price competition shall be shunned
In our country, LED display screen industry basically is developed in a market environment. And LED display industry is fully competitive with high market degrees. Thus, it is very successful in market degrees will cause a worsening price competition. So, it is very important and urgent to advocate a good development atmosphere in the industry.
Development Center Director, Chen Lei says, "Now, display screen makers are in the environment of relatively mature full color screen control technologies. Enterprises shall enhance their profile design and emphasize requirements on accessory-part makers. High end products shall be fine with increasing investments on cast moulds so as to ensure installment accuracy and to be strongly competitive with foreign makers. Meeting basic function needs, middle and low end products shall be simplified in design, lowered in costs and produced in volume, and enlarged in export."
GM Li Chao says there is a poor situation in domestic market competition and market normalization. Some makers strive for customer sources by not-ethnic means thus intangibly affecting product quality. In other industries such as shoe making, examples are very obvious. A hope is that our industry does not go along this bad way. We cannot see a good prospective of market normalization. In the international market, advanced countries have their good normalization in which makers compete by their real strength.

Enterprises should enhance innovation consciousness
In our country, LED display industry has developed fast, including product yield, application range and enterprise number etc. At development level, we are near to foreign makers. Our tech and experts are from colleges and universities all knowing computer skills well. Thus, main defects are in video signal procession and manufacture etc. In the use range, we are higher obviously than foreign makers, such as including expressway, traffic inductiveness, school and community so on.
LED display enterprises are different from that in other industries in development. LED display enterprises go their self-design & self-trial way at their start time. Thus, these have strong consciousness for development and development ability, despite products seem nearly same.
Recently, products are basically custom make so their production is flexible. There is a difference in customer requirements, installment sites and use fields. Thus, we need a group of project tech & production people. The cost is mainly predominated by labor cost in addition to material cost. There is a low requirement for fixed assets and so forth. Obviously, price advantages exist. In near years, this is proved by the fact that product export increases year by year.
LED screen industry due to low requirements on capital and equipment has relatively more small private enterprises with high market degrees. In competition, and use range widening, the industry is successful. On the other hand, newly applied products lack enough reliability with negative influences. However, this has been improved in near time. Now, total production of the industry grows, which is synchronized with the number growth of enterprises. When the market is mature, the industry may enter the adjustment stage.
LED screen makers shall be the high end application of LED industry. LED screen has high requirements in device chromaticity, brightness and view angle etc. It also is strict to reliability. To meet the requirements, there shall be large scale enterprises. Advantages for LED screen are mainly in brightness and large area of displaying, while other kinds of screens have not. Now the semiconductor illumination industry is very hot. From the point of view of colorful illumination, LED has its advantage. On the other hand, it is a long way for real white light illumination to go. Efficacy improvement can lower cost and energy consumption for the device and let un into market. For LED screen industry, it has its advantage in colorful lamp varied-image displaying compared to other device industries.

Basic research shall be combined with practical use
Innovation is a permanent topic. LED display industry has strong innovation ability. On the other hand, the overall innovation level recently in LED display enterprises is restricted by enterprise scale and strength. Enterprises have strong consciousness to product differential innovation, but support is lack. Innovation is very important for development of the LED display industry as a fostering role. Without innovation, enterprises have core competition force so can not meet market needs. In ling time, this will lead to market loss and survival chance loss.
Recently, enterprises lack basic research and LED display theoretical systems based on the front one leading to insufficiency of development work. Our viewpoint is to combine basic research and practical use, to emphasize the combination of short and middle term development and research, and to effectively locate resources what are used well in practice. Enterprises shall concern on investment and development mechanisms, enough enterprise strength, and sustainable innovation and development strategies. In a word, we win by our strategy.

The standard shall meet practical needs
LED screen industry standards offer available tech norm and inspection methods in LED tech performance evaluation from there points: mechanic, optical and electric. Thus, LED screen has its uniform rule.
Standard issuance and implementation is very important for health development in the LED screen market. These standards are very important in LED screen makers doing their relevant work such as design, production, test, quality inspection, installment, acceptable check, tech index use and choice of test solutions and etc. This has a long term impact to improve LED screen product quality and tech levels.
The practice shows that standardization offers good help for LED screen market normalization, tech level improvement, and industry health development. Also this can lift external competition force in the LED screen industry. As tech fast develops and LED industry tech develops, contents fro LED screen standard systems shall be constantly improved and added and perfected so as to adept to the new changes. LED screen standard system has a certain basis. But it is a long way for the whole industry standardization. We shall work hard to enhance the work of standard formulation, research and propagation so as to meet practical needs of the LED screen industry development.
LED screen is the important application for the LED industry in the middle and low end fields. As the new electronic media emerging ant the end of 1980s, LED screen features high brightness, clear pictures and vivid color so on, and has become widely used in public multi-media displaying fields. It is widely used in bus stations, yards, airports, securities, banks, posts, sports halls, shows, business centers, hospitals and plazas etc in which text and graphic information and video images are displayed.
Our country is facilitating the process of information construction in the society, LED screen demands will constantly increase. A development trend is high brightness, full colors, standardization, normalization and multiple structures and so forth. Huge market space and good development potential bring about chances to the LED industry. LED device is a key part of the screen whose yield and value are above 70% in proportion. Its performance and directly affect screen effect and quality. When choosing LED, LED screen makers shall consider some factors such as material, brightness, chromaticity, volume production consistency, work environmental conditions, tech notes, tech exchanges, product reliability, smooth supply channel and short supply time and etc.

Multiple enerprises jointly formulate a standard
In recent years, our LED display industry develops fast. Compared to the first class of level internationally, we have some distance. And this is accorded to our national overall industry level's distance compared to advanced countries. On the other hand, our top makers have a very short distance with the first global class level. In some core technologies, we may be ahead. Our use tech and market suitability are ahead in the world.
The words "third class of makers for production, second class of makers fro management, and first class of makers for standard formulation" mean that each enterprise has its work focus at different development stages. We can understand them as that if you are the third class of maker, then you shall do production. If your product is well, then you can become the second class of maker. Then, you focus on management work. Once your management level in improved, you can be the first class of maker. At the stage, you may consider how to formulate a standard. We do not think that if the third class of maker writes a standard, then it will immediately become the first class of maker. This is wrong. We think that under the recent situation, we are best to let one enterprise as a leader, and multiple enterprises participate in standard formulation. Recent years, several standards in formulation prove the above viewpoint.
LED screen is one of main use fields for LED industry chain. In more 20 years, this brings a development for our country's LED industry. At the start of last century, our screen makers only focused on LED brightness, view angle and other basic tech indices. Today, we concern on light brightness attenuation curve, InGaN-LEDESD (MM or HM) light intensity evenness, tube voltage drop and reverse leakage current and so forth under different work conditions. However, we are regret that most LED makers can not accurately these indices. Even, the LED making industry dares not list these into the standard. In the standard, there is no method to test these indices. This to some extent prevents a high level of whole industry development.
In our country, the LED screen industry has a more than 20 years development. The industry association has a more ten years development with more 100 members. However, we have not seen several large enterprises emerging. The reason is mainly that the industry's entrance threshold is too low with a limited market capacity. In the narrow range of the industry, there are hundreds of enterprises. In this, some enterprises erupts, new ones come. Thus, the competition is hard, and survival space for enterprises is very limited.
In fact, LED use range is very wide, including mobile telephone backlight sources, automobile illumination, LED backlight sources, display screens, building decorative, traffic signal lamps, special illumination, and general illumination and etc. There is a very potential development in its use field. Building decorative, automobile illumination & indication, LCD backlight sources, traffic signal lamps, special illumination are fields worthy of exploration by enterprises and these are our development space.

Do not hurry for standardization
The normalization situation for domestic market competition is poor now. Some makers strive for customer sources by not-ethnic means thus intangibly affecting product quality. In other industries such as shoe making, examples are very obvious. A hope is that our industry does not to along this bad way. We cannot see a good prospective of market normalization. In the international market, advanced countries have their good normalization in which makers compete by their real strength.
For LED display standard system construction, recently we do not hurry for standardization. Some theoretical-level wait for improvement. Some abnormal words are used. Now, we shall normalize not-standardized products, and more mention definition or word normalization. We especially award of that the abnormal use of International Standard words. For example, we often say the brightness in up to the international standard level. But we only see CCIR 601, ITU HDTV No.709 suggestions in the called International Standard regarding brightness. Thus, we shall be very careful.
