What is the difficulty of mini-led conference screen
Industry News 2020-11-20

Small-pitch large LED display screen, with the development of mini-led technology, has entered the P0.X era. This makes the 100+ inch display single-screen product market "lived up all at once." The "non-engineered" LED screens that face single-screen sales in conference rooms are one of the most promising markets for "standard single-screen small-pitch LEDs".

So what kind of product technological progress is needed for LED screens in conference rooms to meet the specific needs of "meetings"? What capabilities and innovations are needed by companies in related industries to truly promote the mini-led small-pitch LED screen market and the new growth in the conference industry?

The visual system needs to be more "close to the eye"

The meeting applications of small-pitch LED large screens are mainly 100-200-inch display screens and products that meet the application requirements of 25-150 square meters of medium-sized meeting rooms. Compared with the traditional large LED screens, these products have a significant application experience difference: that is, it is impossible to ensure that the space between the viewer and the display is large enough—that is, viewing at close range has become a key feature of the LED single screen in the conference room. Combined with interactive applications in front of the screen, this kind of "closer to the eye" viewing demand is more prominent.

Therefore, the application of small-pitch LED single-screen conference room must meet the many new demands of "close-range" viewing in terms of "visual effects".

First, this will be an application scenario dominated by high-resolution products: for example, conference display flat panel products basically reach 4K resolution, and conference projector products have a resolution of 720p or higher. At present, the small-pitch LED products for conferences mainly use 2K resolution products, and the technology has also broken through 4K technology, and further research and development to 8K technology. In the future, it will be able to form a level of fineness comparable to that of LCDs and projectors, and will help to further overcome the problem of pixel granulation. Second, compared with traditional projection and flat-panel display products, the biggest difference between small-pitch LED displays is that the pixels are granular and the brightness is too high. After adopting the mini-led technology, the optical structure design space on the chip side is more relaxed, and it is also conducive to reducing the average brightness, ensuring a better close viewing experience of the product.

Third, the contrast and color advantages of small-pitch LEDs are very obvious in viewing vision. Especially compared with traditional projection conference applications, its bright picture does not require additional environmental shading measures. When used in remote video conferencing, the effect of the LED screen under the camera is also more prominent, and the high refresh rate can avoid the appearance of dark bars on the screen, which is an ideal display technology choice. In short, when mini-led display technology is applied to conference display, it has its own inherent advantages in visual effects; and through continuous technological progress in recent years, considerable progress has been made in "deficiencies". Combining the photophobia characteristics of projection displays and the difficulty of LCD flat panel displays to break through the 100-inch size limit of competing products, small-pitch LED screens are becoming the best "multimedia technology route" for medium and large conference rooms.

Industrial design needs to be more "thin, thin and handsome" Unlike the necessity of display effects, the appearance and installation of products and other industrial design advancements are not "absolutely necessary", but they are also the icing on the cake for "excellent products." On the one hand, the conference room, as a “facade” scene, has a much higher demand for product aesthetics than traditional LED large-screen engineering applications. The all-in-one single-screen small-pitch LED display device can also meet the "more precise" design and craftsmanship of decorative factors such as brackets, frames, LOGO, and indicator lights. This is an important plus factor for the selection of "high-end" customers. On the other hand, from an application point of view, meeting rooms are basically commercial buildings with "inches of money". The equipment deployed therein often requires small size and thinness. Especially considering that the conference room building adopts a frame structure and lacks the necessary load-bearing wall, so the display device installed on the wall must meet the extremely thin design. For traditional large LED screens, "light and thin" is not a mainstream technical requirement in many cases. For professional engineering applications, more consideration is given to convenience in maintenance, rather than one or two centimeters of thickness change and weight reduction.

Therefore, from this perspective, single-screen small-pitch LED conference products, as well as possible home large-screen color TV products in the future, the need for thin and light design is a new problem facing the LED large-screen industry, and it is also a product that further upgrades the application experience. Important dimensions. The large low-brightness LED screen that adopts mini-led technology and is suitable for indoors has greatly reduced its heat generation. At the same time, the product adopts more new packaging and integration technologies, new PCB boards, and even glass substrate TFT drive circuit technology , Can effectively control the thickness and weight of the product, and provide the market with a more "light, thin, handsome" product selection.

The functional system needs to be more "software-defined" Facing the single-screen small-pitch LED large-screen products in the meeting room scene, there is also an important outstanding product upgrade requirement: that is, the traditional engineering display, the main problem facing small-pitch LED companies is only "how to better display" ; But in today's smart interactive conference market, a single-screen small-pitch LED conference display device must be a complete functional body. Not only requires single-screen small-pitch LED display devices to integrate necessary touch functions to achieve better interactive effects; it is also required to adapt to the needs of the smart conference market, integrate smart computing functions, and build a variety of conference function software. It is even necessary to integrate necessary camera, microphone and other sensor components to form an "ALL IN ONE" product.

That is, the small-pitch LED display on a single screen of the conference is not only "no longer a splicing project"; it has evolved into a super smart device. Especially in the face of future 5G application scenarios, a large number of remote video requirements, remote interaction requirements, application innovations in smart office and remote office scenarios; single-screen small-pitch LED devices for conferences will inevitably become "software-defined functions" and "cloud service definitions" Function" new category. "Involving brand-new technical points, brand-new application ecology, brand-new design concepts!" Single-screen small-pitch LED products in conference rooms are bound to be a "challenging industry problem." Industry insiders have repeatedly emphasized that the growth of the LED display market is mainly due to technological advances driving the growth of products in "new application scenarios": this is true for conference screens today, and the same is true for future home color TVs, and the past smart dispatch center screens The same applies to applications, transparent screen digital signage applications, and so on. Therefore, although the issue of "software definition" is a new challenge for small-pitch LED companies, small-pitch LED companies have been coping with product innovation challenges under this "new scenario" for more than ten years, and the industry is confident to complete this mission successfully. The mission is to provide first-class "integrated and integrated" multimedia video equipment guarantee for the conference market, especially in the era of smart conferences.

In summary, the P0.X era of small-pitch LED screens will be another trend of "innovative scenes"! Under the guidance of product technology upgrades, the industry has already begun to conquer the city in the "new space". Carefully and scientifically provide brand-new designed products for new customers and applications. The growth peak of small-pitch LED products is always in the "future"!
