首页 应用 Mini/Micro LED The Mini backlight

Mini LED backlight display products

Compared with the traditional LED packaging side type backlight composed of dozens of large LED lamp beads, Mini LED backlight is a straight down type backlight composed of thousands or even more lamp beads, which is more strict on the luminescence consistency and massive transfer technology.

At present, Mini LED has successfully met the conditions of technology, capacity and yield, and is about to enter the fast lane of development and become a new blue ocean market for LED display.

Advantages of Mini backlight products

1. Compared with OLED, LCD panel with Mini LED backlight design is basically the same thickness as OLED panel, and can also be comparable to OLED in color display. Higher brightness and better reliability bring customers better experience than OLED.

2. It can replace the original OLED TV, and the cost is greatly reduced.

3.OLED is difficult to achieve 8K display, but 8K cell can be combined with Mini COB solution to make up for the blank market of customers' high-order demand

4.Mini POB (Full Sky Star scheme) can achieve thinness, high brightness, high dynamic ratio and high gamut, showing higher cost performance on OD5-12mm medium and high order TV.

Technical strength of Ruifeng:

In 2016, Ruifeng began to cooperate with major customers at home and abroad to develop Mini LED related products. It is one of the earliest enterprises to develop Mini LED in China, and has accumulated certain technology and customers.

The company's Mini related technology can be applied to all kinds of electronic products such as mobile phone, TV, tablet, VR and so on. We have closely cooperated with well-known electronic enterprises at home and abroad to develop all kinds of Mini backlight and display product solutions. At the end of 2017, Ruifeng Photoelectric established the first Mini LED automatic production line in China. It is one of the first batch enterprises to realize the mass production of Mini LED products.

By the end of 2019, the company had applied for 72 patents on Mini LED technology, including 15 invention patents and 2 PCT patents. The company has a certain patent moat on Mini LED.

Mini backlight solution

Mini POB scheme (Full Star scheme), uses 1919 package size lamp beads, lamp beads SMT on PCB, recommended OD between 5-12mm, lamp beads light Angle is large, backlight scheme beads number is small, the cost of the scheme is far lower than the cost of Mini COB scheme at present, is a high quality choice of backlight scheme for middle and high order TV. The products can achieve thin, high brightness, high dynamic ratio and high color gamut. At the same time, the company has the local dimming IC driver solution and PCB layout solutions, which can provide cost-effective solutions for TVS with different sizes and OD values.

Application: esports display, TV

The Mini COB package

Flip Chip is transferred to PCB in large quantities. The Chip of fully flip Mini COB is directly mounted on PCB, and the heat dissipation effect is better through the PCB board. Compared with the traditional SMD packaging, the Chip with fully flip Mini COB is directly mounted on PCB, which reduces the failure factor of bond line eutectic and improves the reliability. Full flip Mini COB technology eliminates SMD bracket and SMT reflow welding link, with no risk of fake welding and higher reliability. Full flip COB does surface protection, which can withstand greater external force, so it can reduce the cost of subsequent damage and maintenance.

Mini COB scheme, a wide range of applications, in mobile phones, watches, VR, tablet, TV and other electronic products can be applied. It can realize ultra-thin, high brightness, high dynamic ratio, high gamut, winding, abnormity and other solutions.

At the same time the company has all kinds of electronic products Mini COB backlight solution ability.

Applications: Mobile phone, TV, tablet, VR and other electronic products
