Micro LED shunts towards large and small sizes. Many people believe that next-generation display technology, Micro LED ("Micro Light Emitting Diode"), is still behind LCDs and organic light-emitting diodes (OLEDs). Although there are many technical product bottlenecks in commercial production, Apple Computer Inc. After vigorously investing in R&D, major international manufacturers competed and Samsung Electronics, LG and OSRAM Opto Semiconductors each developed Micro LED technology. After years of efforts, this year Micro LED may enter preliminary production stage.
In January of this year, Samsung Electronics exhibited a 146-inch module TV using Micro LED at CES. Recently, Samsung Electronics announced that it will launch the world's first Micro LED TV production line in July and produce more than 100 micro-micro LED TVs according to customer requirements. It is estimated that each TV will start at $140,000.
Samsung Electronics' Micro LED TVs will adopt a single-sheet production model, which will be customized to meet the needs of customers. The annual production capacity will be around several hundred units. Samsung Electronics' Micro LED TVs use LED chips and modules, so they can manufacture products of different sizes according to customers' needs. Different from general TV production methods, there is an elastic space of choice.
If Samsung Electronics is able to launch large-sized Micro LED TVs as scheduled, it will be the first step toward the commercialization of Micro LEDs. The current production cost of the Micro LED is very high. Samsung Electronics can sell it for more than 100,000 US dollars. It shows that there is a breakthrough in production technology and yield, and it will be the first to enter the large-size TV market, and it will be able to accumulate technology and take the initiative.
Although Samsung Electronics’ Micro LED TV may be available this year, it may take several years for it to become a practical product in the market. From 2020 onwards, the price of Micro LED TVs may drop to an acceptable level for high-end consumers. The current customer base should be commercial-oriented.
In addition to taking a step toward oversized applications, Micro LEDs may also make progress in small-sized applications.
Apple has actively researched and developed Micro LED technology for several years. It is reported that a breakthrough was made at the beginning of this year and production planning is in full swing. The industry is rumored that Apple Corp. and Taiwan Semiconductor Manufacturing Co., Ltd. and Etron Technology Co., Ltd. will cooperate in technology development. Apple Corp. is likely to commission TSMC to produce Micro LED. It is estimated that Apple Watch will be the first Apple product to enable Micro LED display, and the key components will be produced by the Taiwan factory.
The advantages of Micro LED are high color saturation, large visual angle, fast response, high brightness, low power consumption, long product life, and high efficiency.
The more important feature is that the image does not blur in the sun, which is a revolutionary advantage for portable mobile devices. In theory, the power consumption of the Micro LED is about 10% of the LCD and about 50% of the OLED, and therefore the power consumption is very low.
Apple Watch, which will be available at the end of this year or next year, is likely to start using Micro LEDs. The introduction of MicroLED's Apple Watch will significantly increase its competitiveness. It will not only improve the quality of display, but also increase the battery life.
This year and next year will be the key period for the commercialization of Micro LED technology. The observation is whether the Samsung Micro LED TV will be available as scheduled (August), and the market will evaluate the function and quality of Samsung Micro LED TV, and When Apple introduced Micro LED in Apple Watch.
