PMOLED and Micro OLED Stand Out In the Wearable Device Market

/in /by

At the 4th wearable expo being held from January 17th in TOKYO BIG SIGHT -Tokyo International Exhibition Center, many companies attracted the attention of participants by exhibiting OLED wearable devices and OLED panels. Particularly, at this exhibition, many wearable devices with PMOLED and micro OLED were displayed, which proved once again infinite possibilities of OLED.

First, ColorLink Japan unveiled its VR and AR devices with micro OLED. Micro OLED is a panel that can realize high resolution in small size by reducing OLED panel to micro size. “The micro OLED applied to ColorLink Japan’s VR equipment is 0.7-inch in size with FHD resolution, and we were able to manufacture more compact and scarce VR device by applying micro OLED”, said an official from ColorLink Japan.

In addition, Fitbit and iWOWNfit exhibited smart bands with PMOLED. PMOLED refers to a passive matrix OLED that does not use TFT, which is a switching device, and is mainly applied to low resolution devices that display numbers or characters rather than high resolution-required devices. In relation to the reason for the application of PMOLED, both companies explained that they have been able to significantly reduce power consumption by applying PMOLED, and the OLED prices have fallen considerably so that they have sufficient price competitiveness.

Meanwhile, OLED panel makers also exhibited a number of OLED panels for wearable devices. Pioneer, which firstly produced mono color PMOLED for FM character broadcast in 1997, attracted participants by introducing a number of PMOLEDs and devices using this. Pioneer announced its goal to diversify its business centering on PMOLED, introducing PMOLED-applied Bluetooth speakers, smart watches, and AR devices.

RiTdisplay also attracted attention by exhibiting a number of wearable appliances and panels with many PMOLEDs. RiTdisplay said, “Since the AMOLED market is already occupied by Korea, it is inevitably lagging behind its productivity and price competitiveness”. “Instead, PMOLED enables easy customization with less production cost than AMOLED so it is competitive in the wearable device market.” Also, they announced that since smart bands will be more aggressive in this market due to lower ppi than smart watches and mobile devices, they will actively target the market.

In addition to AMOLED which is leading the mobile device and TV market, various methods of OLEDs such as PMOLED and micro OLED are being actively applied to wearable devices, thereby expanding its influence. The future of OLED, which is being increasingly utilized, is expected.

PMOLED와 micro OLED, 웨어러블 기기 시장에서 빛을 발하다.

일본 도쿄 빅사이트에서 1월 17일부터 개최되고 있는 제 4회 wearable expo에서 다수의 업체들이 OLED 웨어러블 기기와 OLED 패널들을 전시하며 참가자들의 이목을 끌었다. 특히, 이번 전시회에서는 PMOLED와 micro OLED가 적용 된 웨어러블 기기가 다수 전시되어 OLED의 무궁무진한 발전 가능성을 다시 한번 확인 할 수 있었다.

먼저 ColorLink Japan는 micro OLED를 적용한 VR 기기와 AR 기기를 선보였다. Micro OLED는 OLED 패널을 마이크로 사이즈까지 축소시켜 작은 사이즈에서도 고해상도 구현이 가능한 패널이다. ColorLink Japan의 VR 기기에 적용 된 micro OLED는 크기가 0.7 inch에 FHD 해상도로써, 업체 관계자는 micro OLED를 적용하여 더욱 더 컴팩트하고 희소성 있는 VR 기기를 제작 할 수 있었다고 언급하였다.

또한, Fitbit과 iWOWNfit에서는 PMOLED가 적용 된 스마트 밴드들을 전시하였다. PMOLED는 스위칭 소자인 TFT가 적용 되지 않은 passive matrix OLED를 지칭하며, 고해상도가 필요한 기기보다는 숫자나 문자를 표현하는 저해상도 기기에 주로 적용되고 있다. PMOLED 적용 이유에 두 업체의 관계자들은 모두 PMOLED를 적용함으로써 소비전력을 크게 저감 시킬 수 있었다며, OLED 가격도 많이 하락했기 때문에 가격경쟁력도 충분히 갖추고 있다고 설명했다.

한편, OLED 패널 업체들도 다수의 wearable device용 OLED 패널을 전시하였다. 1997년 최초로 FM 문자방송수신용 mono color PMOLED를 처음 양산한 Pioneer는 다수의 PMOLED와 이를 활용한 기기들을 선보이며 참가자들을 매료시켰다. Pioneer는 PMOLED가 적용 된 블루투스 스피커와 스마트워치, AR 기기를 다수 선보이며, PMOLED를 중심으로 사업을 다각화 하겠다는 목표를 밝혔다.

RiTdisplay 또한 다수의 PMOLED가 적용 된 웨어러블 기기와 패널을 다수 선보이며 이목을 집중 시켰다. RiTdisplay의 관계자는 “AMOLED 시장은 이미 한국이 점령하고 있는 상황이기 때문에 생산력과 가격 경쟁력에서 뒤쳐질 수 밖에 없다”고 설명하며, “대신 PMOLED를 통해 AMOLED보다 적은 생산 비용으로 쉬운 커스터마이징까지 가능하기 때문에 웨어러블 기기 시장에서는 경쟁력이 있을 것”이라 언급했다. 또한, 스마트 밴드는 스마트 워치와 모바일 기기보다 ppi가 낮아도 되기 떄문에 이 시장을 적극적으로 공략 할 것임을 밝혔다.

이처럼 모바일 기기와 TV 시장을 주도하고 있는 AMOLED 외에도 PMOLED와 micro OLED 등 다양한 방식의 OLED가 웨어러블 기기에 적극 적용되며 그 세력을 확장하고 있다. 점점 더 활용 영역이 넓어지고 있는 OLED의 미래가 기대된다.

[Wearable Expo Japan 2015] A wearable to take over the future electronics industry

/in /by

With increasing interests in wearable devices, the first Wearable Device Technology Expo 2015 was held on January 14, 2015 at the Tokyo Big Sight including the participating companies of the batteries and electric parts/materials such as a sensor, display, etc. which are to be used for wearable devices. The host announced that the event in 2016 will be about four times larger than this year proving the increased interests in associated industries and expected a drastic growth of the wearable device industry.

The first speaker of the Commemorative Session, Hideyuki Saso, the President of Fujitsu Laboratories, presented that the key for a wearable device is ICT (Information & Communication Technology) which enables every device wearable as applying a sensor and connecting system.

Tomokazu Tajima, the senior vice president of Sony, pointed out ‘co-creation’ as the keyword. He said that the issue for a wearable device is creating a new application through a co-work practice among other players in the industry. Also he estimated high market opportunities of the wearable device industry.

Among 150 companies submitted for the exhibition, WESTUNITIS showed the glasses using the micro display and PPP presented the smart glasses controlling display through hand gestures by employing a sensor and camera at the end of the glasses.

In addition, there were other wearable devices receiving fervent responses as using the glasses, smart watch and sensor including the system automatically informing the work process as linked with a display and embedded sensors in a pair of gloves and glasses, or the system operating a robot to follow the movements of a human wearing the device with a sensor installed in the arm area.

This module was designed by Sony to be a small and light weight glasses-style composed of OLED microdisplay, micro-optical unit, and miniaturized control board.

It is the smallest display module as a 0.23-inch high-resolution (640×480) OLED microdisplay. The contrast ratio is over 10,000:1 with 100% sRGB. Generally the RGB stripe is used to secure the color purity, but this panel uses the optimized matrix configuration.
