Experts say Display Introduction:

html On July 8, Ledman released the 8K 163-inch ultra-high-definition Micro LED giant screen, and officially put it on the Jingdong Mall , and started online booking. It is understood that the 8K 163-inch ultra-high-definition Micro LED giant screen can be used in many scenarios such as home theaters, smart home centers, and commercial applications.

Lehman released 8K 163 -inch ultra -HD Micro LED giant screen

to unveil Lehman giant screen technology architecture architecture

According to experts, Research understands that Lehman 163 -inch 8K ultra -high -definition Micro LED giant screen uses inverted COB technology , screen resolution The resolution is 7680*4320, the brightness reaches 450cd/㎡, the viewing angle reaches 170°, the color gamut range reaches 115% NTSC, and the screen display surface protection level reaches IP65. It is worth mentioning that to achieve 8K resolution at 163-inch size, the point pitch needs to be reduced to P0.46. The P0.46 spacing represents the current high-end technology level of the industry.

Looking at the product as a whole, the Micro LED giant screen has excellent performance in brightness, resolution, color gamut, anti-blue light, response speed and service life, and can be easily installed into the home without the need for a crane or door removal. Because it is self-luminous technology, the screen-to-body ratio is higher, reaching 99%. In addition, the Micro LED giant screen has a built-in powerful intelligent core, which works together with the 8K Micro LED display to present a perfect display effect and a rich interactive experience.

The technological leadership of Ledman giant screen

The figure below shows the iterative relationship of various point spacing products in the current LED industry. It can be seen that the current high-end products in the professional display market mainly use P1.2 and P0.9 pitch products, among which P1.2 is the main shipping pitch of COB, and P0.9 is a higher-priced high-end product. Next are P0.7 pitch products, which are used in a small number of high-end projects. Next is the P0.4 pitch, which represents the current industry’s leading technical level.

For the consumer market, representative products with a P0.4 pitch include the P0.48 75-inch The Wall launched by Samsung , and the ultra-high-definition Micro LED giant screen launched by Ledman this time, with a dot pitch as low as P0.46. It is worth mentioning that the resolution of Ledman's new product reaches 8K in the 163-inch size, achieving the three leading indicators of fine pitch, 8K resolution and large screen of more than 100 inches in the same product.

The industrial value of Ledman giant screen

So, what value can this 163-inch 8K ultra-high-definition Micro LED giant screen product bring to the display industry?

First of all, the arrival of the 5G generation has made 8K signal broadcast a reality, making high image quality and low latency possible. No matter how clear the video quality is, how fast the spread of 5G is, it must be presented by a terminal in the end. To meet the display requirements of 8K, the traditional small-pitch LED display needs to make the screen very huge, and the viewing distance will also vary. Taking it further, this obviously does not meet the actual needs. Under this background, micro-pitch LEDs below P1.0 can achieve 8K resolution below 200 inches and above 100 inches, which will be useful.

On the other hand, brands such as Samsung, Sony , Huawei and other brands focus more on products with sizes below 100 inches. For LED display manufacturers, products with sizes above 100 inches are their advantages, and are larger than 100-inch super products. The TV has made up for the gap in the size of current LCD and OLED TVs. Therefore, in the 5G+8K era, products above 100 inches bring opportunities to LED display manufacturers.

According to Lehman, its 8K 163-inch Micro LED giant screen was developed based on this understanding, because 130~200-inch giant screen can meet the needs of families for watching 8K video material. Based on the above, the P0.46 pitch 163-inch 8K ultra-high-definition Micro LED giant screen released by Ledman this time is a milestone for the LED display industry to enter the consumer market.

The technical threshold behind the product

However, it is not easy to achieve a pitch of P0.46 for LED display products. For traditional SMD packaging, there are certain limitations in the face of shrinkage of point pitch. Assume that the LED chip size is 3*6mil, that is, the long side of the LED chip is 0.15mm, and the distance between the LED chip and the edge of the package is 0.03mm. At the same time, the distance between packages is 0.2mm. Taken together, the pitch limit of SMD packaging is above P0.4. Therefore, needs to adopt the integrated packaging COB method to implement P0.46 pitch display products.

COB technology has certain thresholds, including technical thresholds and financial thresholds. In terms of technical threshold, COB technology accounts for about 70% of packaging technology and 30% of display technology. It is an integration of multi-disciplinary technologies and processes. At the same time, technical problems are not only solved by funds, but also require the accumulation of technology.

Lehman’s technology gene

Therefore, the first-mover advantage in the COB field is crucial. Lehman has proactively laid out COB as early as 2014. It has been deeply involved in COB technology for many years and has an important position in the COB field. It also has mass production capabilities for both COB formal and reverse technology routes. According to research data from experts, Lehman holds about one-third of the market share in the COB field. The 163-inch 8K ultra-high-definition Micro LED giant screen released by this time, , adopts Ledman’s independently developed COB packaging technology and uses more than 100 Ledman’s independent LED patents. is the result of Ledman’s accumulated experience.

Summary:

Experts say Research believes that Ledman’s release of the 163-inch 8K ultra-high-definition Micro LED giant screen is an important part of its strategy to enter the C-end, and the entry of LED display into the C-end is an important trend in industry development. From a series of actions such as technology reserve, product launch, marketing network layout, and flagship store opening, Lehman is successfully transforming its far-reaching strategic vision into practice step by step, especially the launch of 8K 163-inch Micro LED ultra-high-definition giant screen, all technical indicators are among the best in the country. It can be said that Lehman’s active practices are leading the industry into a new era.
