Second generation OLED devices and systems: Inline evaporation, highly efficient OLED devices, and novel driver/controller ASICs

Abstract

Organic light-emitting diodes (OLED) have to be improved to achieve new market segments in displays and lighting applications. We present important steps towards achieving this goal in a combination of highly efficient devices, manufacturing and new driving aspects. It is generally expected that the manufacturing methods have to be made more efficient to achieve large market penetration. We firstly present results on a highly efficient RGB-OLED-system with doped transport layer, manufactured in the worldwide first vertical In-Line set-up. Additionally a second-generation passive matrix OLED controller/driver IC was developed. Though the design was application-specifically directed for the onto integration into an OLED minidisplay panel module (e.g., by pad layout design being closely related to display connection schemes), versatile service in various applications was focused on. Therefore, in general they may also act as application-specific standard products (ASSP), if their built-in functions provide compatibility to a wide range of passive-matrix OLED panels. Additionally, the second generation supports various PMOLED display resolutions, area or full-color (RGB) operating modes and circuit techniques for OLED devices lifetime improvement
