Abstract:In this paper, it is introduced a new touch sensing method for
the flexible OLED (Y‐OCTA) eliminating the chronic
constraints on selecting touch sensing frequencies. In the prior
art, the touch sensing frequencies have been limited to the
display scan frequency(H‐sync) or its harmonics to avoid the
interference effects between Touch and Display operations,
which results in some weaknesses in external noise immunity
for the Touch sensor. This paper proposes a method to
overcome the constraints such that… Show more
