Merck Launches Breakthrough OLED Materials

oled — Thu, 29 May 2008 09:29:46 -0400

Merck KGaA announced today that it is launching several new OLED materials, including a blue singlet emitter (SEB series) that features ultra deep blue color coordinates. Measured in solvent, this dopant shows a color as deep as CIE(x;y) 0.15/ 0.09 with a full width half maximum (FWHM) of only 54 nm.

Sony and Idemitsu Kosan increased the efficiency of blue OLEDs

oled — Mon, 19 May 2008 07:29:46 -0400

Idemitsu Kosan and Sony announced the achievement of 28.5% internal quantum efficiency (IQE) in deep blue fluorescent OLED devices, the world's highest level of luminous efficiency for this technology.

Toray develops blue light emitting materials

Toray Industries Inc announced that it has succeeded in developing blue light emitting materials, boasting the world’s highest levels of efficiency and pure color emissions, for use in full-color organic EL displays.

The combination of Toray’s proprietary molecular design technology and nano-dispersion technology was instrumental in the material achieving superior light emitting performances of luminous efficiency 6 cd/A (candela/ampere) and color purity (CIE(x,y) = (0.14,0.10)) in combination with Toray’s electron-transporting material.

Evaluation of these newly developed materials with respect to its applications is currently underway and Toray is committed to accelerating the process towards its early commercialization.

Idemitsu Kosan and UDC Announce Extension of Collaboration to Accelerate the Development of Phosphorescent OLED Materials

DuPont shows new AMOLED materials and OLED displays

oled — Sun, 03 Jun 2007 01:54:14 -0400

The new set of materials rely on DuPont hole-injection layer (HIL) material and include those essential in the construction of an OLED display, such as light-emitting and charge-transport materials.

DuPont Displays said it has also exceeded the reported performance of other solution-based OLED materials and has measured accelerated lifetimes of the three primary colors that could translate in a display to 20,000 hours of white lifetime (which is extended by as much as five times when showing video) at a normal viewing brightness (200 cd/m2). At 1000 cd/m2 -- the standard test luminance used in the industry -- the DuPont materials have lifetimes (T50) of 14,000 hours for blue with CIE 1931 color coordinates of (0.14, 0.16), 230,000 hours for green with color coordinates of (0.29, 0.65), and 46,000 hours for red with color coordinates of (0.66, 0.34).

Novaled Achieving Groundbreaking Lifetimes For fluorescent PIN OLEDs

oled — Tue, 22 May 2007 06:32:51 -0400

Novaled has achieved outstanding results in lifetime for both, top and bottom emission PIN OLEDs. More than one million hours at an initial brightness of 1,000 cd/sqm have been reached.

Novaled achieved unsurpassed lifetime results for top and bottom emitting red fluorescent devices. A red bottom emitting Novaled PIN OLEDTM shows a luminance drop of only 4% after 6000 hours measurement at a starting brightness of 3,700 cd/sqm. The record top emitting red PIN OLED shows a luminance drop of even only 1% after 1,000 hours measurement at a starting brightness of 12,000 cd/sqm. Both OLEDs are down calculated to more than one million hours (corresponding to one century) at starting brightness of 1,000 cd/sqm.
