The potential of organic semiconductor-based devices for light generation is demonstrated by the commercialization of display technologies based on organic light-emitting diodes (OLEDs). Nonetheless, exciton quenching and photon loss processes still limit OLED efficiency and brightness. Organic light-emitting transistors (OLETs) are alternative light sources combining, in the same architecture,...

The organic light emitting diode (OLED) display has recently become popular in the consumer electronics market. Compared with current LCD display technology, OLED is an emerging display technology that emits light by the pixels themselves and does not need an external back light as the illumination source. In this paper, we offer an approach to reduce power consumption on OLED displays for sequ...

Tien-Lung Chiu (SID Student Member) Haiqing Xianyu (SID Member) Zhibing Ge Jiun-Haw Lee (SID Member) Kou-Chen Liu Shin-Tson Wu (SID Fellow) Abstract — A high-transmittance transflective device based on a hybrid structure consisting of a transparent organic light-emitting diode (OLED) stacked on top of a reflective liquid-crystal device (RLCD) was conceptually demonstrated. By placing the transp...

In this paper, we employ a two-dimensional numerical model to simulate and explore the electrical characteristics of organic light-emitting devices (OLEDs). The spatial distributions of charge and electric field are investigated for structure design of OLEDs. The two-dimensional numerical simulation of the current continuity and Poisson equations are carefully extended to treat the interfaces o...

Exciplex is well known as a charge transfer state formed between electron-donating and electron-accepting molecules. However, exciplex based organic light emitting diodes (OLED) often performed low efficiencies relative to pure phosphorescent OLED and could hardly be used to construct white OLED (WOLED). In this work, a new mechanism is developed to realize efficient WOLED with extremely simple...

Incorporation of duplex DNA with higher molecular weights has attracted attention for a new opportunity towards a better organic light-emitting diode (OLED) capability. However, biological recognition by OLED materials is yet to be addressed. In this study, specific oligomeric DNA-DNA recognition is successfully achieved by tri (8-hydroxyquinoline) aluminium (Alq3), an organic semiconductor. Al...

In this work, we present our achievements in color tunability in novel multilayer organic light-emitting diodes (OLEDs) based on DCM (4-(Dicyanomethylene)-2-methyl-6-[p(dimethylamino)styryl]-4H-pyran) as red emitter doped in a composite PVK:TPD holetransporting layer, DPVBi (4,4′-Bis(2,2-diphenylvinyl)-1,1′-biphenyl) as a separate blue emitting layer, BAlq (aluminum bis(2-methyl-8-quinolinate)-...

With the market for mobile AMOLED displays still increasing, both Samsung Mobile Display and LG Display have announced that OLED TVs will be commercially available in 2012. OLED TVs have different requirements compared to mobile devices and especially the lifetime has to be significantly longer in TVs. Therefore, Novaled has developed new ETL materials that lead to much longer lifetime in monoc...
