Mini LED do OLED status will be under threat?

According to dramexchange LED Consulting Research Center (LEDinside) of the latest "new display technology" cost report, this year showed the highest heat to discuss industrial technology is nothing more than Micro LED, the next generation of display technology to make the capital market as well as the upstream and downstream supply chain industry is under expectation; however, from the technical side to observe, Contains the yield and uniformity of the massive transfer LED, making the Micro LED production road looks difficult. Then part manufacturer focus temporarily transferred to Mini LED, because the Mini LED architecture and the LCD or LED display similar in design, there is no much change, business is only a matter of time before, so manufacturers have been high hopes, we hope it can become a transitional product Micro LED before mass production.

But Mini LED is bound to face competition from OLED directly, whether in the mobile phone or TV and other consumer electronic products, consumers have gradually recognized the OLED panel is equipped with high order products, plus OLED in production stability, even in the future are productivity advantage, so the market also continued to observe whether Mini LED should be aimed at The application of.

The advantages of the Mini technology of LED and OLED respectively

OLED has a high color saturation (NTSC over 100%) and high contrast (1000000:1) and fast response time (microsecond level) and other advantages of self luminescence properties inherent, plus flexible imagination, so that manufacturers in thickness or design have greater flexibility. Mini LED is the current LCD display architecture to 100~200 micron miniature chip size, through the matrix arrangement with the backlight module in LED, also stressed the high contrast, high brightness and has more than 1000nits. In addition, through the partition dimming to realize the advantage of HDR is Mini LED.

Due to the problem of cost and power technology, Mini LED entered the mobile phone market is not small

But many LED several Mini LED products using 5.5 inch FHD screen, for example, the number of LED used as high as 2000~10000 ranging from star. A small number of LED will require a longer optical distance, which makes the increase in the thickness of a number of LED; although you can shorten the distance between optical backlight required and the uniformity is better, but will lead to a substantial increase in cost and makes the problem of heat dissipation.

As a 5.5 inch hard type OLED panel as an example, the cost of the panel fell approximately at around $17~18; if the same size and resolution for Mini equipped with LED backlight panel, the cost will fall at around $35~40, close to the OLED panel "price". With the capacity of OLED is no longer tight, the price from the LTPS panel and the pressure of competition, OLED intelligent mobile phone panels offer the long term is still relatively weak. Therefore, the key of Mini LED into the mobile phone market is to look at the cost when it can be close to OLED.

Large size TV market, Mini LED, or have the opportunity to compete with OLED

In the television situation, because of the printing color OLED technology is not yet mature, and the evaporation material utilization rate is only 20~30%, if used on TV full-color evaporation will face the problem of low rate production yield and material utilization, so the current TV basically dominated by WOLED, also is the Yellow / Green Color collocation of blue light emitting layer mixed into white light, and collocation of color filter to realize full-color. In contrast, although the structure thickness still has advantages, but if the color saturation performance, using Mini LED QD film backlight collocation, have the opportunity to do the same with WOLED level.

65 "the production cost of UHD as an example, the cost of production fell approximately $950~1000; and the 65 inch LED backlight collocation Mini UHD, estimated to use 30000~40000 LED, the production cost about $900~1000. Due to the current consumption of TV is not a priority, plus the cost of OLED as compared with not too much difference, Mini or LED have an opportunity, the recent brands like Samsung and LGE have been demonstrated or declared will launch a large-scale Mini LED TV or commercial display program.

Cost is not a priority, Mini LED battle niche market

When the cost is not a priority when the device import Mini LED opportunities and many display from the beginning of the year, Innolux published in CES 10.1 "car, and before the show with 27 gaming AUO LCD monitor and 15.6 inch 2 inch Laptop, VR and other related equipment, it can be seen that the Mini LED Technology in product at a relatively high niche The market has its space to play.

Because the IT products inevitably need to perform word processing, thus blur the issue of static images produced by OLED had long suffered a lot, plus 2016 because most of the OLED capacity in intelligent mobile phone Samsung display panel as a priority, but also missed the opportunity to enter the IT market. In recent years, with the expansion of the gaming market size of the output value increased year by year, the IT brand is eager for the launch of the gross profit and value added are high gaming products; moreover, the recent PC display also has a HDR standard, Mini LED powerful dimming function partition HDR have the opportunity to play to the most incisive so high order IT products. Mini LED is one of the few will have the opportunity to work with OLED on the same starting line up competition in the market.
