With the market’s increasing requirements for display screens, the spacing of fine-pitch displays is getting smaller and smaller, and Mini-LED/Micro-LED are quickly introduced into the market, and the average LED usage per small-pitch panel is even more geometric. Ascent, in addition to solving the problem of "quantity", there are also "quality" considerations, such as blurry screens, dead spots, and brightness consistency at different viewing angles and etc.
Let’s talk about the issue of “quantity” first. Everyone may have questions. Although the LED usage of the display is increasing, as long as the production capacity of the machine is increased and the traditional pick & place method is used for production, the “quantity” will be more convenient. It's not a problem, why do we need a huge amount of transfer? Due to it, as below the image:
Obviously, the part of the die-bonding using traditional technology is prone to dead spots, and the brightness is obviously inconsistent. On the other hand, the part of the mass transfer technology is not corrected, not only the zero dead point, but also the brightness and the neatness of the arrangement are very consistent. Change the angle to see:
Looking at the display from the side, the effect is more obvious. Mass transfer technology can achieve high consistency and repeatability, and the brightness can still be consistent no matter from which angle it is viewed.
It can be seen that the massive transfer not only solves the problem of “quantity”, but also solves the problem of “quality”. The latest research and development of the mass transfer technology on the market, regardless of Mini-LED or Micro-LED, RGB or back-light, can be applied to solve the problems of blurred screen, dead spot, brightness uniformity at all viewing angles from the root, and help you produce high-resolution, High-brightness, high-end RGB LED display and high-density, high-consistency, high-quality back-light module.
Therefore, with the increasing demand for small spacing of LED displays, the importance of mass transfer technology for Mini LED and Micro LED will also become much bigger in the future.
