Lead: 2017 LED display industry has already opened the prelude to the ups and downs of the past year, the development of the new year's LED display is full of expectations, which, small-distance LED display continues to be hot momentum , From small to micro-spacing, and can achieve the ultimate minimal, it can not mention the COB, COB applications, so that the new LED display shows a more exciting and magical.
COB (Chip On Board): small pitch display technology, that is directly LED light-emitting crystal package in the PCB circuit board, and CELL unit into a display of the technical way.
advantage
1.COB small spacing display technology to avoid the destruction of a single lamp beads, in the waterproof, moisture, dust, oxidation, crash has advantages;
2.COB package can be the existing packaging plant and the display plant a lot of process integration, shorten the process links, greatly reducing manufacturing costs;
3. The existing SMD lamp beads in the handling process of the collision easily lead to damage to the lamp beads, while the COB package will not;
4. COB package due to avoid the SMD through the reflow process, so the reliability of the lamp beads will be higher.
At present, only 2-3 domestic enterprises in different products to achieve mass production, the scale is relatively small, the overall market has not yet opened.
