Small pitch led display are replacing lcd HD display

Small pitch led display are replacing LCD HD display

 

The development of small pitch LED display technology reached a new peak in 2019. Leyard launched 0.6-pitch products, Samsung will push 0.84 pitch products to high-end clubs and villas, and 0.9-pitch 4-in-1 MINI-LED products are almost universal.

The further improvement of technology will inevitably bring about the change of the "application" direction of small-pitch LED products: just like, in history, it is just a small pitch technology, which makes the LED screen becomes the darling of indoor display, smaller spacing, the era below P1.0 How will the market develop further?

Imagination in the era of even smaller spacing

What kind of resolution level does the Liard 0.6 pitch LED screen have? - This spacing is slightly larger than the 1080P 55-inch LCD TV. That is, the 0.6-pitch LED screen can “touch” the resolution threshold of flat panel display technology such as liquid crystal.

The next question is very simple: Can LED screens rely on this indicator to create an application market that “overlaps” with LCD TVs? A significant question for this question comes from the "price"! After all, the 55-inch LCD TV is now priced at only two thousand dollars. However, the 0.6-pitch LED screen, in any case, will cost dozens of times more than a 55-inch LCD TV.

However, things have completely different aspects: LED display brightness effect exceeds LCD TV, can better resist ambient light interference; rely on module splicing technology, there is no "maximum" size limit! In contrast, the price of 98-inch or 120-inch LCD TVs is now around 500,000 - this price is not the level that small-pitch LEDs can't hope to achieve. At the same time, small-pitch LEDs can provide larger sizes: for example, Samsung offers 3m wide 4K images at 0.84 pitch.

If the width of the 4K picture is enlarged to 3.6 meters, then at least 10 local brands can provide a P0.9 level small-pitch LED display system. Therefore, even if Samsung does not consider the resolution limit of the "75-inch 4K" of the 0.43 pitch LED screen displayed by CES in 2019, which is consistent with the mainstream TV, it is 150-inch 4K with the 0.9-pitch technology that has been popularized so far. Television is already a "super new species."

As for the price factor, liquid crystal technology can not provide such a size of the product, does not have a comparative significance; the projector can not provide this kind of anti-environmental light-capable picture has no comparative significance: the only meaningful analysis on the price is that there is The price that the customer of this demand can afford and the potential cost of this product.

For the former, tens of millions of luxury homes, or the "largest electrical appliances" in high-end clubs, the million-level cost can fully bear; for the second question can refer to a historical data: led screen below P2.0 spacing Products, each of which has gradually declined from the price of 200,000 yuan per square meter, until the current P1.5 product is already "cabbage price." - Five years later, p0.9 level products, who can guarantee that the price does not fall to 50,000, 30,000 per square meter?

Therefore, in the future, there may be an LED small-pitch display product, that is, a new competitive situation in which the traditional market is maintained and the high-end and large-size market of liquid crystal display overlaps. The ability to replace LCD in many places will also make this professional product, which used to play a few high-end applications, become the "king of new display" for all kinds of scene applications.

The transition from high-end dedicated to universal versatility

The 0.54 pitch can provide 4K images for 100 inches - the small pitch LED display distance is within easy reach. In the 100-inch to 200-inch market, creating a new demand space has also become a topic of discussion in the industry: this application space covers a wide area of ​​home, teaching, conference rooms, interactive interaction, commercial display and so on.

“At least it is much larger than the highly specialized application space of traditional small-pitch LEDs. If this battlefield can be opened up, the future market size of small-pitch LED products is not limited.” Industry experts say that actively seeking smaller spacing, from small spacing To mini-led, even to Micro-LED, this is the "effort direction" of the technological evolution of the entire industry.

Looking back at the market development of small-pitch LED displays, initially used primarily for display systems and walls in large conference rooms and lecture halls: the core requirements of such applications are reflected in large screens and high brightness. Instead, because of the viewing distance and the impact of the presentation content, there is little requirement for pixel spacing—the highest p2.0 product can satisfy the “basic needs”. Since then, with the improvement of the reliability of small-pitch LEDs, in the professional command and dispatch center market, small-pitch LEDs have achieved “bigger” development: the demand in this market is reflected in high stability, large screen, comfortable picture quality and continuous on. At the same time, due to the upgrade of the display content, the command and dispatch center has also improved the resolution of the image quality. From the initial mainstream P1.5 to the current P1.2, and the upgrade to the P0.9 product.

Of course, the traditional application field of "advertising" LED screen is still the "hands-on" of indoor small pitch LED displays. However, since the advertising market is a more sensitive area of ​​“input and output”, the small gap products with smaller gaps can not meet the cost requirements for a long time: that is, the indoor small pitch led screen does not get rid of “larger pixels” and “large” The shackles of screen advertisements; in the small and medium-sized digital signage market, "the tree is broken." This high-resolution and cost-improving feature also limits the expansion of small pitch LED display in the outdoor “small and medium-sized signage” market.

“If the cost of smaller spacing is too high, then look for a market with a large viewing distance and a low sensitivity to resolution spacing.” Industry people use this description to summarize the current “small pitch LED screen market pattern”. In other words, the resolution spacing level, the resolution requirement caused by the viewing distance, and the product cost level become the key to the “it is the key to the iterative growth of the small pitch LED display market”. Among them, the viewing distance represents the "product versatility level."

Only smaller spacing indicators can meet the smaller viewing space requirements: this is also the basic rule for small pitch LED display to go to larger markets. For this reason, the industry believes that the popularity of P0.9 products promoted by the four-in-one mini-led technology and the possibility of further advancement to the 0.6 level indicates the possibility of “unprecedented growth” of the small pitch LED screen product market: from high-end dedicated to The technical preparation for universal turning has been basically ready.

How to perform a general-purpose small pitch LED display "scale-cost" iteration

“Technology continues to break through just the 'foundation' of the generalization of small pitch LED screen. The work after that is more complicated and complicated.” Industry experts believe that the technology maturity of small-pitch LEDs and the cost advantages brought by cost and scale, two The contradiction is an important bottleneck for the industry to further expand the scope of product use.

On the one hand, technology maturity is still a huge problem. In Liard's 0.6-pitch product, the four-in-one lamp bead technology effectively avoids the “difficulty of yield” of “mass bulk transfer of Micro-LED”. However, the surface-mounting process after this technology still requires the processing level of 1.2-pitch components and far exceeds the "electrical wiring" difficulty of P1.2 products. The latter still has a profound impact on the reliability and yield of the entire screen.

However, the industry believes that if a larger scale CELL integration process such as "16-in-1" can be used, the difficulty of the back-end process can be effectively reduced. However, from four in one to sixteen in one, the difficulty of batch transfer and packaging process is inevitably increased. Therefore, how to balance the “yield rate” between the package and the terminal, and continuously improve the cost and improve the production efficiency on the basis of the improvement of the process proficiency is the key to the solution of the “technology-cost” contradiction.

On the other hand, one of the more important aspects is the relationship between “scale – cost”. In fact, the market scale not only directly affects production costs, but also sales and after-sales costs; even larger application scales are the basis for “mature and advanced manufacturing processes”. This determines the "scale-cost" contradiction, the "decisive significance" in the process of generalization of small pitch LED display.

However, the current lack of ultra-fine pitch LED display screens is engineering applications, and the key to blocking engineering practice is the “cost” is too high: therefore, the industry is optimistic about the promotion of giants such as Samsung and Liard – this is the expectation Giant companies use the longer-term, larger-scale project losses to cultivate the entire market, thus achieving a positive and healthy development of the “scale-cost” feedback chain.

"The more the market is, the more versatile the field, the more it needs a big leader, the big move!" Industry experts pointed out that the only way to cross the "scale-cost" feedback threshold is this one.

Turning to the versatile market is not only an upgrade of the technological revolution but also a cultural change.

"What is the versatile small pitch LED display era? It is the application that can be seen in other display categories, LED screens may be involved." Industry sources pointed out that in the face of the development of narrow pitch LED display technology, mobile phone screens, electronic watches On the screen, LED technology may appear: GM is not "only a big screen", but "big, medium and small, all kinds of applications, civil, engineering, consumer electronics, commercial use."

In the face of such application scenarios, technological advancement and cost reduction are inevitable market growth prerequisites, but for the LED industry, the change is not only the case: more importantly, the LED industry is experiencing the intersection of “out of the engineering display”. -- Facing new technologies, new product categories, and new application markets mean new channels, new marketing, new brand image and new corporate culture.

“From dedicated to GM, it is also a round of 'culture' revolution in the fine pitch LED display industry!” For example, at the IFC exhibition in 2019, Samsung’s home products emphasize customization, expandable to 292 inches and can be between 2K-4K resolutions. Customize the specifications you want. Samsung named the home product "The Wall Luxury", and "Luxury" also reflected the definition of the target customer base and cultural integration.

It is also because of the decisive significance of the power of culture in different markets, especially in the consumer market. Industry experts believe that the development of a generalized narrow pitch LED display market will be a complex industry shift: at least this change is no longer "Simple technical advantage" can be the only thing left and right. “When things get complicated, the industry will differentiate.” Industry experts believe that the generalization of HD LED screen is an important node for the large-dimension LED industry.

In summary, advances in technology will ultimately drive qualitative changes in applications. The market structure of small pitch LED display is not "pure imagination," but what many companies are already doing. This new market trend will trigger an industrial revolution, we will wait and see
