[SID] 5000cd/m2OLED lighting panel sample debut

MITSUBISHI heavy industries, Rohm, letterpress printing and Mitsui products announced the establishment of the OLED lighting business feasibility study company, and at the news conference on the display of the brightness of the sample panel 5000cd/m2. Based on the panel, the mass production development goals are also announced.

Brightness of 5000cd/m2

According to the narrator, the sample panel performance indicators include: the shape of the size of 150mm * 150mm * 3.9mm, brightness of 5000cd/m2, luminous efficiency of 20lm/W, the brightness of life (half life) for 6000 hours. Glass substrate, heavy 300g. Border for 5mm, can also be made of borderless products. The next two years the development goal of the panel is to maintain the brightness of 5000cd/m2 in the case, the thickness will be reduced to 2.5mm, the luminous efficiency will be increased to 25lm/W, life will be extended to 10 thousand hours. Also intends to develop the same size but only about 50g of the weight of the panel.

Lumiotec on behalf of the board of directors, said: not only the use of 15cm square floor, has been made using 50cm square glass substrate after the panel. As the size increases, the plastic floor will be used, and the development of flexible panels.

The ultimate goal of efficiency is 70lm/W

At present, the luminous efficiency of the product is 20lm/W, has exceeded the incandescent lamp, but the ultimate goal is to achieve the fluorescent lamp 70lm/W, the goal will be implemented in a few years later. Luminous efficiency, other companies have announced higher than the company's digital data, but the brightness is 1000cd/m21000cd/m2 for lighting, the brightness is not enough. In addition, the OLED panel manufacturing joint venture company, science and Engineering Research Professor Shiroto Juji Graduate School of Yamagata University and its basic structure, developers said: multiphoton structure of single layer, 1000cd/m2 is the limit. By using the multi photon structure to stack 2 to 3 layers, the brightness of the 5000cd/m2 equivalent to the fluorescent lamp can be realized. In this brightness, with other structures are not up to 25lm/W".

The target is a 20% share of the Japanese domestic market

Aimed at the idea of lighting market business development: Japan reached about 500 billion yen, Japan Overseas reached 7 ~ 8 times, "and began to supply the Japanese domestic lighting market (500 billion yen) 20%" (Lumiotec). MITSUBISHI heavy industry, said: in the global market, although not a blank, but where to start, to be determined in the next 2 to 3 years.

In addition to the sample panel lighting appliance manufacturers, but also ready to transport building materials manufacturers, machine manufacturers, design firms, art galleries and museums, Lumiotec said, in addition to customers before, will also sell to potential customers, in order to explore the new demand. At present, the price of the sample panel for each of the tens of thousands of yen, for mass production fell to 5000 yen.
