Organic "color changing materials" (CCM) are efficient down-conversion light emitters. Multi-color emission from blue converted into InGaN LED array to green, white, yellow and red emission.

  • Hybrid inorganic/organic luminescent devices

    In this paper, we review the field of hybrid I/O luminescent devices (organic LEDs, inorganic LEDs and insulator-based ELDs) that combine inorganic and organic materials. Organic "color changing materials" (CCM) are efficient down-conversion light emitters. Multi-color emission from blue converted into InGaN LED array to green, white, yellow and red emission. Emission spectra from blue, green, and red CCM pumped by an InGaN UV LED emitting at 400 nm.

  • High efficient self-assembly CdSe/ZnS quantum dots light-emitting devices in organic matrix

    We have fabricated and investigated the effect of CdSe/ZnS quantum dot (QD) concentrations on self-assembly hybrid organic/inorganic light emitting diodes (QD-OLEDs). The uniform distribution of QDs with controllable density was achieved using the conventional spin-coating method. There was a QD threshold concentration below which there was no emission from the QDs. The estimated QD concentration was around 9 × 10<sup>11</sup> cm<sup>-2</sup> for the best performance of QD-OLED. The QD emission was increased about three times by annealing of QD-OLED.

  • Drivers for OLEDs

    Organic light emitting diodes (OLEDs) are expected to become important light sources in the future. In contrast to point source inorganic LEDs, OLEDs are large area device. This in combination with different materials results in differences in performance and electrical behaviour, which on their turn result in different drivers. This work gives an overview of OLED characteristics. Based on these characteristics a simplified equivalent circuit is obtained and driver requirements are derived. It is found that AM dimming is preferred. Additionally, some OLED characteristics are compared with those of inorganic LEDs.

  • Energy Loss Mechanism in Organic and Inorganic Light-Emitting Diodes

    We report that there exists a similar energy loss mechanism in fluorescent/phosphorescent organic light-emitting diodes (F/P OLEDs) and inorganic semiconductor optoelectronic devices [1310-nm InGaAsP-InP superluminescent diodes (SLDs)]. The loss of energy in inorganic SLDs based on thickness-altered asymmetric multiple quantum-well (QW) structures occurs depending sensitively on the sequence of QWs, an analogous behavior also observed in F/P OLEDs depending on the sequence of phosphorescent dopants for different colors. It is shown that such an energy (power) loss is evitable by placing long-wavelength QWs near the p-side in inorganic SLDs and similarly long-wavelength phosphors near the hole-transporting layer in F/P OLEDs.

  • Polymer and Small Molecules Light Emitting Diodes - A Technology for Large Area Low Information Contents Displays

    Polymer Light Emitting Diodes (PLEDs) and Organic Light Emitting Diodes (OLEDs) have made great progress in terms of efficiency, brightness and lifetimes during its last few years of development. The technology looks mature enough to produce real commercial products like high-resolution flat panel displays for cell phones, computers and televisions. However, it is also quite promising for low information content displays. In this work, the technology of low information content displays like 7-segment and simple billboard type of displays using polymer and small molecules has been developed. The processes, structures, characteristics and advantages of OLEDsand PLEDs over LCDs and inorganic LEDs are presented.

  • Frontier of organic light emitting devices

    We report recent progresses on organic light emitting devices such as organic light emitting diode (OLED), light-emitting organic field effect transistor (LE-OFET) and organic laser diode (OLD). We demonstrate very low driving voltage of OLEDs using a p-i-n structure which also provides high current carrier injection over kA/cm<sup>2</sup>. Further we demonstrate novel organic devices such as light emitting FET. We also discuss future prospect of OLD based on our recent materials' development and analysis of operation mechanism.

  • Hot Laminated Multilayer Polymer Illumination Structure Based on Embedded LED Chips

    The dominant technology for manufacturing backlight illumination structure (BLIS) is typically based on the use of individually packaged surface mount device light emitting diodes (LEDs) and special light guide plate (LGP) and diffuser films. The prevailing BLIS package, however, contains several separate diffuser films, which results in a thick and costly structure. In addition, the light coupling from LED to the LGP is sensitive to alignment errors causing nonuniform and inefficient illumination. We have demonstrated a novel hot laminated packaging structure for backlighting solutions, which is based on inorganic LED chips and multilayer polymer structure. The main advantages of the implemented system compared to the traditional light guiding system are easy optical coupling with high efficiency in an integrated and thin package. The performed designs of 3×3, 5×5, and 5×7 LED chip matrices, verified by test structure implementations and characterizations, showed that the final thickness of the BLIS depends on the required uniformity of illumination, allowed LED device pitch and efficiency of the diffuser. The final BLIS demonstrator size was 50×75 mm2consisting of six 25×25 mm2modules. Each module consisting 5×5 LED devices resulting in total number of 150 LED devices with 5-mm pitch. The measured key characteristics of the demonstrator were as follows: average brightness 11.600 cd/m2(ILED= 2 mA), luminous efficiency 22 lm/W, color temperature 5550 K, commission on illumination values (x = 0.331, y = 0.411), Color Rendering Index ≥ 70, and total power conversion efficiency of 6.3%. The combination of the developed Matlab performance simulation tool and cost-of-ownership cost evaluation tool enables us to estimate the manufacturing cost of a specific BLIS element against the required performance, assisting decision-making in different applications and specific individual customer cases.

  • Photonic crystals for lighting applications

    Summary form only given. Solid state lighting is developing rapidly, offering great promise in applications from displays to genereal lighting. Both in organic and inorganic LEDs are pursued, for ever increasing brightness and efficiency. A crucial aspect of the efficient operation of these devices is the extraction of the light from the emissive layer. After a brief overview of more conventional approaches, we discuss the influence of photonic crystal structures on the emission, and their potential for improving efficiency and beam shaping. We conclude with some developments for the more distant future, such as full three-dimensional photonic crystals and non-periodic structures.
