Author information


In the 22th International Display Research Conference held in NICE, 24 and 10 papers have been presented in the sessions of organic and inorganic electroluminescent(EL) displays, respectively. In organic-EL(Organic Light-Emitting Diode: OLED), a lot of research results were reported concerning organic material and design such as dye-dopants, hole-transporting layer and carrier injection layer. In addition, unique devices such as transparent EL, high-contrast EL and highly reflective EL were introduced together with topical theme "Top emission structure" and "Triplet exciton". Impurity doping technology with "n-type" and "p-type" dopants attracts a great deal of attention in Late News. Furthermore, 2.1-in. diagonal passive drive full-color EL display and polymer micro-display with 0.2-in. diagonal size have been presented in poster session. In inorganic EL, 17-in. full-color video prototype display was reported and demonstrated with an advanced performance. The blue efficiency was significantly increased, so that further improvement of green and red phosphor should be discussed for the high quality image of EL display.
