The classification of COB small pitch LED display covers a variety of models. Compared with the traditional SMD package LED display, COB small pitch LED display has a significant difference. This is because the COB small-pitch LED display is mainly aimed at the point spacing market below P1.5, and the difference between them is mainly reflected in the difference in the point spacing. For example, Kang Shuo exhibition currently launched three COB small spacing LED display, respectively P1.56, P1.25 and P0.93.

Introduction to 1. Technology
COB small pitch LED display is a packaging technology introduced in recent years. It changes the defects of the past SMD packaging, such as complex process and easy to drop lights, and directly packages the LED chip on the PCB board. This greatly enhances the stability of the entire screen, and eliminates reflow soldering, so that the distance between the lamp and the lamp can be smaller. This is also the biggest technical feature of COB small pitch LED display. The advantages of this technology can be summed up as follows:

1. Smaller point spacing. Compared with SMD patch technology, the dot spacing of COB small-pitch LED display products is mostly concentrated in P1.2 and below, thus significantly improving the resolution level of the entire screen. However, the main point spacing of the traditional SMD packaged LED display screen has been above P2, such as P3, P4, P8, etc. Although point spacings like P1.875, P1.56, and P1.25 can also be achieved, they cannot always break through the spacing below 1.2. Therefore, this is also the main reason for the introduction of COB small pitch LED display.

2) Better stability. Due to the change of the packaging structure of the LED chip, the lamp beads of the COB small-pitch display are more stable, so it is not easy to drop the lamp. Whether in the packaging process or in the installation and use process, the lamp beads on the entire PCB board are very stable, which greatly reduces the lamp drop rate and reduces the demand for after-sales maintenance.

 

2. product classification

1、P1.56

One of the most mature products in the COB small pitch LED display. Although the dot spacing is large, the technology of this product is very mature. It adopts a box-type design, the box size is 600*337.5, and it is currently in large-scale use.

2、P1.25

This is currently a hot-selling COB small pitch LED display, in improving the screen resolution at the same time, can still effectively ensure the quality of the product. It is one of the main products used in some high-end large screen display market. This product has mature technology and good clarity, and is one of the mainstream products on the market in the next few years.

3、P0.93

This is a COB small pitch LED display newly developed by Kang Shuozhan, which greatly improves the clarity. In addition, combined with the inherent non-patchwork technical characteristics of LED, it provides users with a more high-definition, non-patchwork large-screen display alternative. With the continuous maturity of products, the future will become the main market products.

As a well-known COB small spacing LED display R & D and manufacturer in the industry, all LED products of Kangshuozhan Company are produced independently, and have a number of patented technologies in the industry, which has become one of the manufacturers worthy of attention in the industry.
