Mini LED is up and down, and the status of OLED will be threatened?

According to the latest report of the LED Research Center (LEDinside), the latest new display technology cost report, this two years shows that the technology that has the highest heat in the industry is no more than the Micro LED. This generation of display technology is looking forward to both the capital market and the upstream and downstream supply chains; however, from a technical point of view, The good rate of transfer, as well as the homogeneity of LED, makes the Micro LED's way of measuring production difficult. Some manufacturers then transfer the focus of development to Mini LED temporarily. Because the architecture of Mini LED is similar to the current LCD or LED display, the design is not much changed in design. Commercialization is only a matter of early and late time, so it is also expected to be a transition product before Micro LED.

But Mini LED will directly face competition from OLED, whether it is in mobile or television consumer electronics, consumers have gradually recognized that the OLED panel is equal to the higher order products, plus OLED in production stability, and even future capacity is more advantageous, so the market is also continuing to observe the Mini LED should be aimed at the aim. Those applications.

The technical advantages of Mini LED and OLED

OLED has the advantages of high color satiety (NTSC over 100%), high contrast (1000000:1), and fast reaction time (microsecond grade), as well as the inherent advantages of the self luminescence characteristics, as well as the flexible imaginary space, allowing the manufacturer to have greater elasticity in thickness or exterior design. Mini LED, in the framework of the current LCD display, shrunk the chip size to 100~200 microns, full of LED in the backlight module through matrix arrangement, and also emphasizes high contrast, and has super high brightness over 1000nits. In addition, HDR is also one of the advantages of Mini LED through partition dimming.

Limited to technical problems, such as cost and power, it is difficult for Mini LED to enter the mobile phone market

But the number of LED products used in Mini LED products is very much, with 5.5 inch FHD screen as an example, the number of LED used is as high as 2000~10000. When the number of LED is less, a long optical distance will be needed to increase the thickness of the whole machine. While the LED can shorten the optical distance required by the backlight and have better uniformity, the heat dissipation problem will be derived and the cost is greatly increased.

With a 5.5 inch hard OLED panel, for example, the cost of the panel falls about $17~18; if the same size, the same resolution is replaced with a Mini LED backlight, the cost of the panel will fall at about $35~40, close to the "price" of the past OLED panel. With the OLED capacity no longer tight, and the price competition pressure from the LTPS panel, the OLED smart phone panel quotes are still relatively weak in the long run. As a result, the key to Mini LED's access to the mobile phone market is to see when its cost will be close to OLED.

The big size TV market, Mini LED, or the chance to compete with OLED

According to the situation of television, because the printing technology of OLED is not mature yet, the utilization rate of the current steaming method is only 20~30%, and if the full color evaporation will face the production rate and the low utilization rate of materials on TV, the TV base is now based on WOLED, that is, yellow / green. Color with blue light layer mixed into white light, and coloring color filter to achieve full color. Although this architecture still has advantages in contrast and thickness, it is possible to use Mini LED to match the backlight of QD film with the same level as WOLED if it is shown from the performance of color saturation.

For an example of a 65 inch UHD production cost, the cost of production falls at about $950~1000, and the 65 inch UHD with the Mini LED backlight is estimated to be about US $900~1000 with 30000~40000 LED. Since power consumption is not a television priority, and the cost is not much more than OLED, Mini LED or the opportunity to take a chance, the recent first line brands like Samsung Electronics and LGE have shown or announced plans to launch large Mini LED TV or commercial display screens.

Cost is not a priority, Mini LED is a niche market

When the cost is not a priority, the opportunity for the device to import Mini LED is much larger. From the beginning of the year, the 10.1 inch vehicle display panel published in CES, and the 27 inch LCD monitor, and the 15.6 "pen power, 2" VR, and other related devices, which are displayed by the former friendship, can see that Mini LED technology is relatively high in the unit price of the product. The market has its own space.

Because IT products are unavoidable to carry out the processing of documents, the problem of the long static picture of the static picture has made OLED a lot of trouble. In addition, in 2016, the OLED production capacity of Samsung display is mostly based on the smart phone panel, and it has also lost the opportunity to enter the IT market. In recent years, with the expansion of the competition market scale and the increase of output value year by year, the IT brands have also been trying to make the competitive products with higher value and higher value. Furthermore, the PC displays have HDR standards recently, and the powerful zoning function of Mini LED has the opportunity to make the HDR hair incisively and vividly, therefore, the high-order IT product It will be a market where a few Mini LED will have the opportunity to compete with OLED on the same starting line.
