Refond Mini LED Screen Display Solution

Recently, with the development of Mini/Micro LED screens, the market structure is slowly changing. In the field of small pitch (≤P1.25) display, domestic and foreign display manufacturers have successively launched Pitch 0.9-1.25 products and are actively deployed extra-small pitch displays. Moreover, many traditional panel manufacturers are actively involved in the "battle for the future display market" through capital and technology development and launch-related products, open up the channels to seize the market.

For traditional SMD packaging, the processing accuracy and difficulty increased because the single LED device is so tiny that the existing equipment cannot satisfy the production of smaller pitch products. As a result, the flip-chip Mini COB package technology is the solution of the Mini LED screen.As a result, the full flip-chip Mini COB package technology structure was born.

Compared with the traditional SMD package, Advantages of flip-chip Mini COB:

- Effectively avoid the problems caused by humidity, static electricity, and other environmental or human factors in small pitch LEDs of traditional SMD packages.

- Uniform light emission to eliminate moiré and reduce glare effectively.

- Equipped with four solder joints, the flip-chip Mini COB dissipates through the PCB board directly, which can obtain a better dissipation effect.

- The flip-chip Mini COB directly mounting on the PCB, which reduces the failure factor of the bonding wire eutectic and improves the reliability.

- With higher reliability and without the risk of soldering, Mini COB technology eliminates the SMD lead frame and SMT reflow soldering process.

- The strong surface protection can withstand greater external forces, which can reduce subsequent damage and maintenance costs.

Experience you can rely on

Having 20 years of packing experience, though, Refond has early made its way to flip-chip technology, investing a lot of research and development.

In 2016, it began to cooperate with major domestic and foreign customers to develop Mini LED screen display. At the end of 2017, Refond built the first Mini LED display automated production line in China. This Mini LED screen manufacturer successively developed P0.9, P0.6 extra-small pitch, and P0.4, P0.3 tiny pitch products, cooperating with customers to participate in industry exhibitions many times.

Mini LED Display

Refond Mini LED screen display with two series products:

The First Series: COB Module, which involves module, cabinet, and comprehensive solution.


The drawing of Display control system Solution

Second Product Series:uPKG Series

- Refond Micro PKG is much smaller than lead frame type components, thus enable smaller board size, higher

- packing density, reduced storage space and finally smaller equipment to be obtained.

- Bond wire breaking is avoided because of flip chip;

- PKG without cup,180°radiation;

- Moreover, with its black PCB, the Micro PKG possess an ideal solution for high-contract and high-resolution
