P-138 Systems-Level Comparison of Singlet- and Triplet-Based Full-Color AM-OLED Displays for Power, Lifetime, and Color Gamut

In this paper, we compare the performance of full-color AM-OLED displays fabricated from singlet- and triplet-based materials. A systems-level approach was used to evaluate material performance, in terms of contribution to display power consumption, lifetime, and color gamut. Display architecture techniques were evaluated, such as microcavities and color filters, to enhance the performance of the display. Materials used for the evaluation included high-performance OLED materials from Kodak and published results from other OLED material manufacturers.

P-147: Highly Efficient and Stable Blue OLED Systems

This paper will discuss combinations of a new blue dopant and a new blue host that produce superior luminance and efficiency for blue OLED devices. Furthermore, this blue system provides excellent operational stability that enables superior performance in both monochrome and full-color displays. Devices exhibiting this outstanding performance are simple in architecture, robust with respect to dopant concentration, and require no co-doping to achieve optimal performance.

P-169: Efficient, Long-Lifetime OLED Host and Dopant Formulations for Full-Color Displays

We report developments in materials and formulations for blue, green, and red fluorescent OLEDs that provide lifetimes exceeding 15,000 h for a model display operating at 200 cd/m2 with a polarizer. In addition, we describe improvements in electron transport and injection that result in a reduction in display power consumption of up to 55%.

Advanced materials and formulations for OLED display manufacturing

This paper describes Eastman Kodak Companys commercialization efforts to develop new materials and formulations for monochrome and full-color displays. We have found a new set of materials, and combinations thereof, that improve luminance efficiency, lower drive voltage, and increase the operational stability of OLED devices. We report the developments in formulations for blue and white OLEDs based on fluorescent dopants that provide lifetimes exceeding 10,000 hours for blue, and 50,000 hours for white OLEDs at a starting luminance level of 1000 cd/m2. A red formulation, based on a fluorescent dopant using a new host, is shown to give a record luminance efficiency of 7.8 cd/A combined with excellent color and lifetime. We have found a phosphorescent red-emitting device using a novel host material that gives an excellent efficiency of 9.6 lm/W. Further progress has been made in a new electron-transport layer to reduce display drive voltage, and thus reduce power consumption, while simultaneously increasing operational stability. We have compared this performance with currently available systems.

30.4: Deep‐Blue OLEDs with Exceptional Device Lifetime

A novel class of group 13 electron-transporting materials and a strategic device architectural approach were used to advance the power efficiency and lifetime of deep-blue OLED devices. The advanced efficiency and exceptional device lifetime of these devices were enabled by material advancements. These advancements shed light on a possible mechanism linked to improved device lifetime.

5.2: Performance of Highly Efficient Electron Transporting Materials in OLED Displays

In this paper, we describe a new class of highly efficient electron-transporting materials evaluated using basic and advanced organic light-emitting diode (OLED) device structures. Data collected showed that the new class of materials provides higher device efficiency with lower operating drive voltage resulting in lower power-consuming devices. Competitive device lifetimes were also observed with some device structures showing significant improvements for the new materials. The data presented in this paper show that the advancements in efficiency and drive voltage can be realized in blue and red devices.
