43.2: Mutual Capacitance Touch Screen Integrated into Thin Film Encapsulated Active‐Matrix OLED

A thin and high performance input/output device consisting of capacitive touch sensors integrated on thin film encapsulated AMOLED is described. Internal electric field distribution and capacitance change trend was simulated to find and prove the optimal structure including touch input and display output units. To verify cross-talk free operation of touch sensors on thin film encapsulated AMOLED, 4 inch diagonal size display-TSP prototype was fabricated.
