N2 - A light-addressable potentiometric sensor (LAPS) is a field-effect based sensor. With a modulated light source, spatially resolved measurements of chemical species can be performed and chemical images can be generated. The modulated light source is used to define the particular measurement spot and to achieve spatially resolved signals. In this work, an organic-LED (OLED) display has been chosen as a light source. This allows a high measurement resolution and miniaturisation of the system. A new developed driving method for the OLED display for optimised LAPS-based measurements is shown, which is possible to define modulation frequencies between 1 kHz and 16 kHz and to reduce the measurement time of a chemical image by a factor of 40.
