The aim in this thesis is to develop an intelligent system to drive an OLED or an OLED panel (consisting of different OLED tiles as shown in the picture on the left). One important element will be the design of a feedback loop to eliminate non-uniformities between different tiles or to compensate OLED degradation effects, so that the lifetime of the OLED system can be enlarged. Furthermore, some sensors to enable human interaction features can be added to the system. One could e.g. embed motion, touch or sound sensors. With the aid of such local intelligence in a lighting wall or ceiling, the light could actually follow the position of a person. Furthermore, advanced communication features, e.g. by means of power-line communication (PLC) techniques across the power supply lines, can enable intelligent brightness control from a central unit. The communication between the OLED driver chip and the central CPU should be bidirectional. By using the power lines, additional communication lines are avoided, resulting in less complex interconnections patterns on the backplane of the OLED panel. Of course, some kind of address assignment (e.g. by means of an on-chip FLASH address register or through dynamic auto-configuration) is needed to distinguish between all chips in the system.
The electronics will be implemented on board or on chip level depending on the preference of the thesis student. The student is also free to choice on which of the different subtasks described above he wants to focus.
