To say which field in 2016 is a dark horse in the LED industry, I believe that the small-pitch LED display is well-deserved. It can be said that the small-pitch LED display ushered in explosive growth in 2016. It is expected that in 2017, the small-pitch LED display industry will usher in greater development opportunities.

As we all know, small-pitch products are positioned in the high-end application market, with high product prices and high profits. With technical support, small-pitch LED display combined with bare smart application, cloud platform control, naked-eye 3D, VR and other technologies, the display effect is more creative. , attracting many users to pursue.

At present, there are more and more small-pitch LED display manufacturers on the market. In the face of market explosions, the layout of enterprises is also different, and the technology is constantly making progress.

Stepping into 2017, the debut of "COB Small Spacing LED" has brought a refreshing look to the industry, breaking through the competition of "smaller and smaller" in the past.

This also means that for the entire LED display market, LED products are no longer divided by different pitches. Different packaging technologies have become another key to distinguish and select LED products.

Previously, for users, the choice of small pitch LEDs was more of a choice between different pitches, while the pitch primarily affected the resolution per unit area for small pitch LEDs.

Now, compared with different packaging technologies, COB small-pitch LEDs are greatly improved for SMD small-pitch LEDs, both in terms of technological innovation and display effects.

According to the relevant person in charge of Guoxing Optoelectronics, compared with the traditional SMD lamp bead patch, COB has many advantages, mainly reflected in the following aspects:

1. The COB package can integrate many processes of the existing packaging factory and the display factory to shorten the process steps and greatly reduce the manufacturing cost;

2. The collision of the existing SMD lamp bead during the handling process is likely to cause damage to the lamp bead, while the COB package does not;

3. The COB package is more reliable because it avoids the reflow process that SMD is subjected to.

It is undeniable that the COB small-pitch display technology can avoid the damage of a single lamp bead, and has advantages in waterproof, moisture-proof, dust-proof, anti-oxidation and anti-collision; in addition, the shortening of the manufacturing process of COB also greatly reduces the cost.

However, the person in charge of Guoxing Optoelectronics said, “At present, only 2-3 companies in China have achieved mass production on different products, the scale is relatively small, and the overall market has not yet opened.”

Indeed, the current COB market share is still relatively small, due to problems such as contrast, color consistency, low pass-through rate, etc., and there is no large-scale production of P1.2 and other mainstream point spacing products, so COB The problem solved is not enough to reflect and truly exert its advantages.

"For the prospect of COB small-pitch display technology, we are neutral. Because there are still many technical problems in the existing COB on the market, and the mass production of SMD0606 has realized the high-density micro-pitch screen of P0.X, this is COB. It is difficult to reach in the short term, so we think that COB still has a long way to go. Of course, we will continue to pay close attention.” Guoxing Optoelectronics, the person in charge, told Gaogong LED.


Terminal Pins

The pin refers to the connection between the internal circuit of the integrated circuit (chip) and the peripheral circuit, and the pin constitutes the interface of the chip. According to the function, the pins of AT89S52 can be divided into four categories: main power supply, external crystal oscillator or oscillator, multi-function I/O port, and control, strobe and reset.
