29.5L: Late‐News Paper: Advanced AM‐OLED Display Based on White Emitter with Microcavity Structure

Abstract

We developed an AM‐OLED display having saturated RGB, high efficiency and good contrast ratio. These properties, which outperform those of a conventional White OLED and color filter (WOLED+CF) system, were achieved with a unique combination of white emitter, microcavity structure and color filter array (WOLED+MC+CF).

Finite Element Study on the Micro-cavity Effect in OLED Devices

“…When the resonance occurs in the microcavity structure, the resonance condition of the Eq. (10) is satisfied [3,4]. Fig.…”

“…In this structure, the light passes through each layer and experiences the reflection at the two reflecting layers. For certain width of the device, this structure can exhibit the resonance effect, which is called as microcavity-structure [2,3]. When the resonance occurs in the microcavity structure, the resonance condition of the Eq.…”

“…The reflective layer acted as a bottom mirror of cavity and the transparent conductive layer was used to adjust the optical length of cavity [6]. An additional thin protection layer was introduced over the reflective layer to prohibit reflective metal electrode from oxidations or damages during lithography process, and also from contaminations of beneath layers.…”

Unconventional, Laser Based OLED Material Direct Patterning and Transfer Methods

“…Sony demonstrated the WOLED+CF prototype display at SID 2003 (Kashiwabara et al 2004). However, high power consumption and color impurity are the issues of this method for the TV application.…”
