Mini LED, it seems, is still LCD in essence, but because of fine light control, it greatly reduces the gap with OLED in brightness and contrast, and more importantly, there will be no screen burning problem.The news that Apple will launch the new iPad Pro as early as April may mean that the yield of mini LED screen iPad Pro has met the high standard set by Apple, and will start mass production this year.

Apple is about to launch Mini LED backlight products, TV brands are also introducing Mini LED, and manufacturers have launched Mini LED notebook computers before, and related business opportunities are gradually emerging.

Greathome believes that in the first half of the year, benefiting from housing economic demand, coupled with the rush to establish safety inventory after the epidemic, the second half of the year is expected to maintain the traditional peak season level, at the end of this year, customers are expected to launch a number of large size Mini LED backlight TV, at the same time in order to capture market share, also began to lock business opportunities to prepare for, scheduled production capacity, It is estimated that FPC circuit board manufacturers will benefit from the operation to maintain growth.

Greathome said that the display is an important product line, the company will not be absent from the Mini LED industry chain, but also stressed that the Mini LED is no longer in the research and development stage, the market to see related products.

This year, the company will prepare mass production of Mini LED FPCB circuit board, which the market believes is for the main customers of Mini LED high-end tablet or notebook computer needs, will not comment on a single customer or product, only said that compared with the market often mentioned TV, esports screen, etc., invested in research and development, suitable for smaller display, more precise, thinner products. Its technical threshold is higher.It has not confirmed what the follow-up application will be, only that it has begun to layout the sample delivery certification of Mini LED related products, which is expected to be in volume by the end of this year.

Mini LED business opportunities also extend to the equipment factory, AOI equipment factory Mude said, there is the launch of Mini LED FPCB measurement/appearance full inspection equipment, but is indeed the next mainstream, the future will be amplified.

Greathome believes that the Mini LED faster development is also better, but the unit price is expensive market to overcome the problem, but although the challenge is still in, but more and more brand factory import Mini LED technology, the faster the popularity is expected, there will be more supply chain investment, can accelerate to drive technology improvement and cost optimization.For Mini LED, Greathome believes that it will also promote the growth of FPCB circuit board market.

Mini LED is an improvement of LCD technology, which can easily achieve 8K and also break through 65 inches in size, which can bring more excellent visual experience to consumers.

Big strides forward at the consumer end mean that the technology on the front end is also growing rapidly.

From the perspective of packaging, the packaging form of LED products has developed from single-chip packaging to multi-chip packaging, and the packaging structure has also changed from pin type packaging (Lamp) to patch type packaging (SMD), and then to substrate surface assembly packaging (COB).

Given the Mini LED's small diameter (50-200μm), small pitch (100-300 μm), and high density (each Mini LED circuit board usually has thousands of chips, tens of thousands of solder joints), traditional SMD packaging technology is obviously unable to meet this demand.

COB (Chip on Board)

Different from SMD table-mount package, COB is the LED bare chip directly mounted on the PCB board for lead bonding, through which the circuit board is bonded to passivation and protection of the chip.

This method minimizes the spacing between LED, effectively improving the LED display light color; By omitting the high temperature overreflow process, the reliability of the whole system is improved, the risk is reduced and the cost is saved.
