-To come out with a successful organic light-emitting diode (OLED) lighting business, it is very important to have clear differentiation of OLED from LEDs. Flexible OLED has merits, such as capability to be mounted on the curved wall, which is not easy for LEDs to achieve the feature. There are several approaches to make flexible OLEDs especially among those plastic barrier films that can bring high level of flexibility, which could not be achieved by any conventional lighting method. In this paper, barrier films with various water vapor transmission rate values, including 10 À 6 order, are applied, and the conditions to have almost no dark spot growth under 85°C and 85% high temperature/humidity test are shown. Flexible OLED panels are manufactured with the world's first roll-to-roll equipment using plastic barrier film.

“…Barrier films may be believed as most common flexible substrates for flexible OLED devices at present. Indeed, many flexible OLED displays are reported to utilize flexible barrier films [3]- [5] and R2R fabrication of flexible OLEDs with barrier films has also been reported [6]. However, the gas barrier technologies of barrier films still have issues because of the expensive cost, the difficulty of production, etc.…”

-A flexible vertically stacked flexible polychromatic color-tunable OLED has been developed by means of low resistive intermediate electrode technology. The polychromatic OLED has a capability to show 16 million colors with 105% National Television Committee Standard (NTSC) color reproduction. The device can produce arbitrary shape with arbitrary colors, suitable for artistic expressions, just as many as those used in information displays. Independently controlled red, green, and blue lightemitting layers are stacked vertically. With conventional indium tin oxide technology, because of the temperature restriction, it was quite difficult to achieve low resistance on plastic substrate. The reported numbers were all more than 80 Ω/□. According to the surface mobility control using Fick's law analysis, low sheet resistance 7.34 Ω/□ on plastic film was developed. At first, flexible 7.17 cm 2 transparent OLED was fabricated for the performance confirmation of transparent electrode. And then polychromatic color-tunable OLED with the same size were successfully fabricated on plastic. With optical length optimization for each color stack of polychromatic OLED, more than 100% color reproduction in National Television Committee Standard was achieved by stack design. The polychromatic device can be used for colored illumination, as well as for organic-light-emitting display pixels for three times emission than conventional pixel design. The device is fabricated on plastic substrate so that the polychromatic organic-light-emitting-diode device is manufacturable with roll-to-roll production line.
