If 2013 is a small distance between the first year of LED display, then 2014 would be a little distance between the outbreak of the LED display in: technology further development, and marketing the product quantity, brand and sales doubled, became one of the main features of the outbreak of small spacing LED display!
Small spacing LED display stage of development
Why LED companies keen on small spacing of the development of LED products? Answer has three aspects: first, the traditional outdoor products technology gradually govinda, indoor small spacing products into the future the main technology development space, which influence the interest of upstream manufacturers products for small spacing; Second, traditional outdoor LED market fierce price war, falling profits, terminal enterprises urgently need to find new sources of growth, improve the level of profit; Third, indoor display, especially the market into a variety of technical stalemate phase, the market opportunity, to develop the products and enter indoor engineering market, can realize the traditional LED enterprises "refactoring" business structure. Thus, the emergence of small spacing LED not only the inevitability of technology, also has the enterprise active market choice, more capital chasing the instinct of the benefit and expansion drive.
What is the definition of a small spacing between the LED display? There is no clear answer to this question. Ten years ago, the P4 the following screen is called small spacing; Five years ago, small spacing refer usually P2.5 product; Now only spacing of P2 is less than the product is called the small spacing. Thus, since the LED display industry into the fast development, the pursuit of high resolution products, small spacing is industry an important direction of development and progress.
At present, the market mainstream products refers to the small spacing P1.6, P1.5, P1.2 level of other products. One of the pixel pitch 1.2 MM products, is the highest density of pixels in mass production products. From the laboratory products, 1.0 MM products has reached production level, 0.8 MM, product has reached all the key technology of node is one of 14 years in the second half of the main product, smaller pixel pitch products also to have certain research and development. Among them, most notably, P0.8 products, can already on the 50 to 60 inches display size, to realize the quality and output of 2 k standard; P1.5 level products to meet the level of 100 - inch screen full high-definition display. - these standards, although is well behind states such as liquid crystal 4 k display capability, but fully meet and exceed national high-definition standard, conform to the requirements of the current mainstream audio signal resolution, resolution requirements for most indoor display application.
P2 may also be responsible for the following products mature and proliferation, LED display industry is the strategic demands of "small spacing" enter indoor, and become in LED outdoor highlighted display of falling prices, under the background of the increasingly fierce competition in the market, the key direction of the development of the industry. Incomplete data show that LED industry since 2010, after more than 7-8 into a research and development of resources used in the small distance between products, and its related IC, packaging, etc. But, even so, small spacing of large-scale application of LED display there are difficulties in technology and industry.

Small spacing LED display two prominent dilemma

Pixel resolution, or pixel pitch, has achieved the thorough breakthrough: LED display pixel density is close to plasma,

 LCD, DLP, it is famous for its high density shows such as display technology, on the large size products 10 years ago, the typical application of resolution, and meet the needs of hd now mainstream applications, hd with even more than national standards. For the LED display industry it is a great progress. But, LED the application of small spacing products still brightness and price two huge challenges.

Research data indicated that the P1.2 to P2.0 level of the brightness of the LED display basic small spacing between 1000-1600 lumens, far higher than indoor TV, LCD splicing wall, the mainstream of the 300-700 lumens DLP splicing wall brightness level. The key feature of high brightness LED display products. In LED array type three styling market application products: LED outdoor screen, the LCD with LED module light source and LED lighting products, highlighting is one of basic, the core of performance requirements. However, small spacing is a LED display products have additional requirements.
Why the LED display industry to develop small spacing LED display products? The answer is enter indoor application market. Such a statement is very easy to be understood, but did not reveal a little distance between the core application characteristics of the LED display products. This feature is based on the indoor space, in the application of the viewing distance is less than 5 m distance. Most traditional LED screen, outdoor viewing distance in tens of meters, pursuit of such products is high brightness. Small spacing LED requires the application in 5 meters distance. Future 0.8 mm products, and even can be applied in the 3 m - such a close watch on viewing distance, higher brightness means dazzling, means that viewers feel ill. Usually, the brightness values of 3 meters viewing distance had better not exceed 450 lumens, to produce more comfortable.
Thus, if you want to achieve the goal of small spacing LED display indoor application, not only to achieve small spacing, also in order to achieve low brightness. But, LED lamp bead products, the technology and principle of decision highlights the characteristics of the LED display has a natural: LED lamp bead light is a typical current drive, high brightness mean big current; Low brightness will need to reduce the current level. However, the current in the LED semiconductor material through, have leakage phenomenon. If the current is too small, the leakage current will be displayed to the overall effect, color, gray, brightness have disastrous destruction. Development, therefore, is suitable for low current, low light environment materials, drive, process, improve the LED lamp bead and drive system adapted to the low current work, is the key to a small distance between the LED industry progress direction.
Troubled LED display screen market application of small spacing another problem is the product price. Indeed, from the display effect such as color, contrast, LED display obvious advantages. But, on the price, the high pixel density, small spacing LED display are almost the DLP splicing, projection display, liquid crystal display (LCD), plasma display, the most expensive in the oled display.
Market information shows that in 65 inches display screen, for example, the price of LCD and plasma under ten thousand yuan; Projection display different prices are different because of the brightness, but for the most part cost up to tens of thousands of yuan category; DLP rear projection splicing product prices are between 70000 and 200000. Under the corresponding display area P2.0 pixel pitch of LED display price is between 100000 and 300000-1.5 times its price is significantly higher than other display technology to more than 20 times. Among them, in the public, the high-end market, small spacing of LED display, at least, is the price of other optional display technology more than three times.
Although small distance between the LED display products are mainly in the face of the engineering application market, the market is not a price sensitive market. But, because of the great difference, and small spacing of LED display in the period of start-up, lack of market awareness, product still has the brightness to progress, must become obstacles to the popularization of the small spacing LED display core obstacles.
Look from the cost, LED small spacing product key cost focus on lamp bead. Lamp bead occupy the total cost at least 65-75%. And in the future, with the progress of product process and technology, the increase in the demand of quantity, research and development costs, diluted, the yield of light bead product price will have a larger decline in space. In addition, the LED display packaging, IC driver cost is not low. The cost reduction of the space is lesser. But the mass under the background of application of the future, equal spacing products still eager to compress two to forty percent of the cost - but, due to the smaller distance between products will speed up the popularization, the smaller distance between products mean higher unit show that the size of the drive and packaging costs, so the package cost how to reflect on the change in the final market price, is still unknown. On the other hand, due to transportation and the growth of the human cost, LED display screen of the small spacing engineering deployment cost will be difficult to drop, more likely to continue to rise. Product packaging is more precise and at the same time, due to the small spacing unit can repair of casing failure will be lower than big distance between product a lot, and small spacing products demand a higher death rate of light control level, and even could be as high as the traditional die light rate of ten big one over ten thousand to one over twenty - it will also enhance customer lifetime usage cost.

On the whole, however, LED product price decline is still small spacing. The author thinks, the small distance between the LED products to achieve comparable prices and DLP splicing wall, have better visual and sound effects at the same time, will be a big probability event. But compared with LCD and OLED future, led small spacing products will not have a price advantage.
Small spacing LED display of the target market
LED display products, gradually mature small spacing has gradually into the various market segments: these apply to LED display small spacing product segments, although has the character that focus "on screen", but not strictly distinguish between residential, commercial or engineering field.
First of all, in the domestic market, high density small spacing LED display screen, whether be best inches level home theater, villas, private halls and other high-end residential places like "TV product" choose one of the operational areas? -- at least, such as liquid crystal display technology to the corresponding level of product price is as high as millions; Projection products application level, although the prices are lower, even only tens of thousands of yuan, but you need to "turn off the light show," a limited impact. At present, a lot of LED display enterprise with small spacing LED TV concept, already has a good domestic market. As early as 20 years ago, on the other hand, LED display case has been for domestic, although at that time the display effect is coarser, these all reflect, in particular household niche, the advantage of LED display and opportunities.

Second, small spacing LED products in the field of commercial application prospect is considerable. The commercial 

applications mainly index word signs, including custom large screen display unit and finished product of different forms, such as products, the LED can be overlapping and LCD products have market. Commercial field, however, LED hours spacing products difficult to get the LCD price, need and liquid crystal dislocation competition, play their "highlighting the features and advantages, focused on the" public "under the advertising effect of the application.

Third, the engineering application shows, LED small spacing product advantage is not small. The effect of both the display quality advantage: brightness, contrast, look more beautiful products LED small spacing is more suitable for the stage, news live broadcast and other occasions - small spacing in these areas of LED products and even get than traditional DLP display wall, LCD splicing wall greater recognition. And in the field of security, scheduling command center, the LED products have "splice joints" small spacing on the inherent advantages, at the same time, the cost will be comparable with the DLP, also completely has the chance to occupy a certain market share. However, in the lower part of the conference room, the monitoring center market, because the customer is more sensitive to price, the market LED small spacing to stir up the LCD products difficult to girder location.
Fourth, LED products can challenge engineering projector small spacing of many applications. Including stage effect, larger classrooms and conference exhibition application, engineering the projector on the edge of fusion and virtual simulation applications. In these areas, small spacing of the high brightness LED does not become a "big problem", but may be advantage. LED display unit can be spliced and arc deformation ability, can be customized, and conducive to the play better "creative design" the effect. In addition, the effect of these areas is preferred, the price is not sensitive to the market
To sum up, the LED road with small spacing of product applications does not distinguish between household, civil and engineering; Focused on large size display, focused on the characteristics in the field of high-end. The potential market, all is a high return on the market, products and services at the same time, focus on the market, and many even creative engineering market. The future market, small spacing of LED display and engineering projection, DLP splicing wall competition conflict, will be far greater than competition conflict and liquid crystal display products. This is a lot of DLP domestic companies involved in the key reason for the small size LED display field.
Small distance between the main characteristic of LED display product market competition
In the short term, small spacing on the application of LED display products main "high-end brand", will be the primary market characteristics of the industry. This is not only determined by the price of the product LED small spacing, and by a variety of technology and the industry as a whole according to decision and the realities of competition environment, and even LED the purpose of the enterprise.

For LED industry, LED display small spacing is a trump card, they can not only depend on the product recovery and 

improve their profit level, promote the growth of itself, more means to enter a new market: indoor markets. The traditional display and engineering industry, because of different technical characteristics between different enterprises, constitutes the significant market barriers and differences. Basic trapped in outdoor LED enterprises, market, super bright display areas over a long distance. Security applications on the higher end, command and dispatch center, city and indoor culture creative wisdom had limited market, even in the digital sign in emerging markets has failed to get rid of the dominance of LCD technology.

However, now have a little distance between LED products mature, on the basis of the products and technologies, LED enterprises also have and DLP splicing wall, engineering projection, LCD display technology, even in engineering, business, education, culture, security in indoor applications in many fields, such as the possibility of expansion, the expansion of territory. In a sense, small spacing LED technology, will open a door for the traditional LED enterprises the door to new "the mainland". Therefore, LED enterprises have enough motivation and determination to promote the application and development of this product.
But the LED products to enter the show indoor engineering companies relying on the small spacing in the field of strategy, must touch the traditional indoor display engineering companies of cheese. LED products and small spacing DLP splicing wall competition conflict is obvious. As a traditional domestic manufacturers, whether digital bulletin, splicing wall enterprise, engineering projection system and service enterprises will not lay down and die.
LED display screen expected by the large size, small spacing high-end indoor display market is not a "virgin" : the territory had been split up. The partitioner came from different technical camps, projection, LCD, plasma, also from different industry "mother", is famous for its engineering of gen, barco is famous for its hardware, predominantly service DE hao, based on the panel upstream resources and color TV business such as samsung... These companies each has its own characteristics and strength, they will not easily give up already eat into the mouth of the indoor display market.

As a way to fight back, on the one hand, traditional indoor domestic enterprises can launch its own LED products, small spacing and traditional LED enterprises take on positive (although the traditional LED enterprises with the advantages of technology, but traditional indoor domestic enterprises have the advantage of market and contacts). Traditional indoor domestic enterprises, on the other hand, can be agents of some brand products LED small spacing - although not involved in the new technology products, but it can hold in the hands of both the customer and market; At the same time, more traditional indoor domestic enterprises will promote other technical advantages, LED products, small spacing, with the attitude of technical route competition small spacing encirclement and suppression of LED products.
No matter how small spacing LED products market expansion, the traditional indoor display enterprise customers and market advantages, LED emerging technological advantage, will be the main competition; And technical route of the disputes over the superiority of the product under different technology, also will be more intense. In this match, or the parties "to play" stage now, but not to the period of new pattern, divided into indoor engineering shows that the market is still a diversified competition era, there was no significant monopoly, LED products with small spacing in the development of time and space; As a new technology, LED products, small spacing is vibrant, up the development of technology, with the advantages of public opinion and propaganda; LED product is still in the price down, small spacing quality promotion channels, technology space than the traditional industries such as projection; Indoor project strong display is a service industry, is customer strong industry relationship, LED enterprises should find both customer relations, customer service, plunder more share; Indoor display is still in high-speed development stage, an annual increase of the size of the market, which is beneficial to the LED small spacing this new class of technology market development; Indoor engineering market is highly profitable industry, the survival of small spacing of the LED industry and products do not need to be on the basis of the size of the market - as a result, small spacing LED display technology products and traditional engineering competition will certainly is a long-term battle.
All in all, from the market point of view, small spacing LED is LED enterprises choosing a historical opportunity, is a traditional indoor domestic enterprises and the traditional technique of a big competition and challenge. At present, small spacing LED product is still in rapid technology evolution stage, into the 1 X times later, was approaching 0. X times - it will be the limit of the LED display technology. In such a change in the technology leading, anything is possible. Either LED or traditional indoor domestic enterprises, have to cope with the inevitability of the storm "market", have clear consciousness and preparation, to seize the opportunity of victory.
