LED vertical integration manufacturer Lextar Electronics registered a revenue of NTD 760 million (USD 25.97 million) for February, down 21.7% MoM. The company attributed the revenue decline to the Chinese New Year holiday and product mix adjustment.

Here begins a debate: when Mini LED is ready to enter the smartphone display market, it have to face an oversupply of OLED screens. Does Mini LED still have chances to grow in this space? And for how long can it last?

LEDinside would like to thank everyone for your support and regular visit to our online magazine. As Chinese New Year is approaching, we will temporarily stop updating industry news until February 21.

Integrated Systems Europe (ISE) 2018 in the Netherlands is an international well-known exhibition for display. This international exhibition is taking place from February 6 to 9 in the Netherlands and has caused a lot of attention in the digital display industry.

LEDinside listed out companies worldwide that have tapped into the development of Micro LED and what they have achieved so far. This up-to-date table covers the majority of the activities happening within the global Micro LED developing force. 

Innolux yesterday (February 6) demonstrated a 10.1-inch AM Mini LED display at a shareholder meeting. This new technology will be officially commercialized in the automotive electronics market, said Chin-Lung Ting, Executive Vice President of Innolux Corporation. Before that, the Taiwan-based company will continue the development of other devices.

Last year, Taiwanese LED packaging company EVERLIGHT registered a lukewarm annual earnings with a YoY decline of 6.6%. In face of looming threats from Chinese competitors, EVERLIGHT adjusts its product mix in hope to push up its revenue in 2018.

A KAIST research team led by Professor Keon Jae Lee from the Department of Materials Science and Engineering and Professor Daesoo Kim from the Department of Biological Sciences has developed flexible vertical micro LEDs (f-VLEDs) using anisotropic conductive film (ACF)-based transfer and interconnection technology. The team also succeeded in controlling animal behavior via optogenetic stimulation of the f-VLEDs.

Finance of Taiwanese LED giant Epistar saw a noticeable recuperation last year. The market this year anticipates Mini LED, one of Epistar’s new lineup, to generate a revenue for the company in 2H18.

Since Apple joined to share some of the OLED supply for its iPhone X in 2017, the shortage of OLED panels has become intensified. Because of the agreement Apple signed with the exclusive supplier Samsung, Apple always stays in the list as the top priority that a large proportion of the OLED supply goes to. Other smartphone manufacturers struggle as they also want to use OLED panels for their products but the supply is simply not enough. Thus, they, the Chinese smartphone brands in particular, turned to Mini LED.

According to the latest report from LEDinside, a division of the market research firm TrendForce, 1Q18 Micro LED Next-Generation Display Technology Market Report- 2018 Micro LED and Mini LED Industry Trend, the Micro LED market value in 2025 is expected to reach USD 2.891 billion.

Self-driving car, electric vehicle and internet of vehicles are three major trends of automotive panels. Innolux takes part in the 2018 CES to exhibit the world’s first AM Mini LED automotive panel.

In retrospect, companies had already realized the only way to earn themselves new opportunities in such a mature market is to redevelop their technologies and gear up for niche markets with higher margins. LEDinside picks five trends that drove the LED industry this year and gives a quick analysis on what they will lead the industry to in 2018.

Taiwan-based LED chip manufacturer Epistar announced its business plan for 2018 will be around five cores—backlighting, high-end LED lighting, infrared application, automotive lighting, and innovative digital display. Ming-Chun Chou, General Manager of Epistar, stated the company will officially produce Mini LED in 2Q18 at the earliest.

Epistar General Manager Chou Ming-Chun revealed at the company’s investor conference on December 5 that Mini LED is likely to be mainstream in the backlight market.

LEDinside, a division of TrendForce, points out that LED manufacturers have turned to research and development of Mini LED, due to Micro LED’s technological bottlenecks which make it harder to realize commercialization in short term.

Taiwanese LED chipmaker Epistar reported a decline in revenue in October due to the slow season and estimated 4Q17 sales less than that of 3Q17. However, Epistar’s outlook for 2018 is positive with the momentum from collaboration with display makers on Mini LED-lit displays.

Mini LED has a high chance to help Taiwanese LED manufacturers reclaim the leading position in the high-end backlight market in 2018. It rekindles Taiwanese firms’ hope against the ‘OLED attack’ from Korea, expected Bingjie Li, Chairman of Epistar.

There are many recent articles explaining mini LED or Micro LED. Some are correct, but some are not. Let LEDinside explain and tell you the differences between fine-pitch LED, mini LED and micro LED.

According to the latest report from LEDinside, a division of the market research firm TrendForce, 4Q17 Micro LED Next Generation Display Industry Market Report- Micro/Mini LED in Automotive Display Market, the total passenger car display in 2017 was about 241 million sets and is predicted to total 624 million sets in 2025, CAGR of 2017-2025 is 13%. The growth driver comes from rising IoV penetration, new energy carand autonomous vehicles. Hence, interior automotive display usage volume significantly rose.

The next generation display technology Micro LED draws lots of attention, but Micro LED will take time to reach the mass production (MP) phase. Before that happens, mini LED with lower technical barrier will enter its MP phase first. Sources said, panel makers and LED die manufacturers already started their collaboration. Initially, mini LED will be used for two major categories: signage and TV panel backlight source. The cooperative effort will launch ultra-fine-pitch signage and super energy-saving, ultra-slim direct lit mini LED backlight TV panels.

Osram Opto Semiconductors is expanding its existing portfolio for flash applications with a product featuring a specially developed chip sized package (CSP). With Ceramos C, Osram is following the trend for miniaturization as the new LED is the smallest yet in its product family. It is ideal for flash applications on smartphones etc., producing perfect illumination for every snapshot.

The LED industry had quite a peaceful time in 1H17. Apart from a few M&As, the most-discussed technology would be Micro LED. Lots of high-tech giants worldwide have already started a series of R&D and the number of participants is getting bigger. The supply chain of Micro LED, although of limited mature technologies, is slowly shaping up. Here, LEDinside lists out major events and milestones made on the path of developing Micro LED in the first half of 2017.
