This paper presents 2-(hydroxyl) quinoline lithium (Liq) used as an n-type dopant to improve white hybrid organic lightemitting diode (WHOLEDs) performance. The Liq doped tris(8hydroxyquinolinato) aluminum (Alq3) layer possessed enhanced electron injection, efficient hole and electron balance in the emitting layer, as one of the most essential issues for device applications. This work investiga...

Ultrathin non-doped emissive layer (EML) has been employed in green phosphorescent top-emitting organic light-emitting diodes (TOLEDs) to take full advantages of the cavity standing wave condition in a microcavity structure. Much higher out-coupling efficiency has been observed compared to conventional doped EML with relatively wide emission zone. A further investigation on dual ultrathin non-d...

We proposed a structure of patterned TFT array films to prevent the macro‐cracks, which was implemented on foldable organic light‐emitting diode (OLED) display. The out‐bending tests demonstrated that protection can improve reliability. And limitation bending radius achieved 1.5 millimeter.

Organic light emitting diode (OLED) technology uses substances that emit red, green, blue or white light. An OLED panel consists of stacks of several thin layers of different materials, as such it is not easy to inspect the common OLED defects. In this paper, an autooptical inspection (AOI) system which can detect such defects effectively and robustly was proposed and developed. The proposed sy...
