If there is a small gap and then "small", is there any meaning?

50 years ago, Gordon Moore published a famous opinion in the electronic magazine "Electronics": "The number of transistors incorporated in a chip will approximately double every 24months. The number of transistors on a semiconductor chip will increase by one every two years. Double)."

As a result, the legendary Moore's Law was born. Nowadays, the semiconductor electronics industry, Moore's Law, also vividly reveals the speed of information technology progress. The LED industry is also the same, just as the small-pitch LED products were not optimistic when everyone was not optimistic, but now, everyone's glasses have fallen below.

Then, according to the development of the existing form, after the pitch of the small-pitch LED display screen is small to a certain extent, will it continue to be “small”? Will the paranoia of Moore's Law continue to make the small distance continue to be “small”? How do you think about it? this matter?

"It is true that from a purely technical point of view, it is achievable to continue the distance between small-pitch LED display screens. But I want to emphasize that this implementation can be commercialized, has a high cost performance, or Maintaining a competitive advantage with other competitors is closely related," said Lin Jilin, executive director of Mulinsen.

The reason is that the main advantage of LED display is the realization of the demand for large and very large display screens, but the large or very large display screen itself does not have such high requirements for resolution, for example, for large or super For large displays, a P value of 1.0 is already considered a relatively high product.

"And, compared to OLED screens and LCD screens, P-values ​​are not dominant in the cost of small-pitch products below 1.0. I think P1.0 will be a turning point, because P1.0 is mainly in the LCD, OLED or plasma display market. It will be used more, and because the P value is small, the volume will not be too large, and the special field will have a 'useful place', but it will not become mainstream in a short period of time," said Lin Jilin, general manager of Mulinsen.

“I believe that because LED displays have strong advantages in terms of reliability and environmental adaptability, small-pitch products with smaller resolutions are generally applied in some high-end, differentiated and special occasions, with small spacing. If you go down, there will be a certain market, but the market share will not be very large. According to the current market development needs, products with a price above PM1.0 should occupy the mainstream of the market.” Dr. Shao Pengrui, Technical Director of Jingtai To.

Perhaps, when the small-pitch LED display device develops to a certain extent, the advancement of technology will become very slow, but each improvement may be a qualitative change, and each progress may be a big step in the industry.

"The pursuit of technology in scientific development is endless. Perhaps, the development of small-pitch LED devices in the future is no longer limited to 'small'. In addition to developing smaller devices, we must pursue how to make 'small' devices. The display is better, the life is longer, and the quality is better.” Ouyang Xiaobo, general manager of Guoxing Optoelectronics RGB Devices Division, said.

Indeed, when you make a superior price/performance ratio, there will be people in the market to pay the bill. While you are still struggling with the small spacing and continue to make sense, there are already many manufacturers who continue to work toward the micro LED, and the technology is changing with each passing day. Maybe after a few years, when we look back at the so-called small spacing, we might feel that it is not small.

All in all, how small the small spacing can be, depending on the application market, there is a need to create...
