Abstract
In this paper, a method of reducing horizontal crosstalk
artifacts due to the coupling effect of data lines and ELVDD
electrodes in each pixel of a mobile active matrix OLED display
is proposed. In order to achieve this, this paper presents a method
for calculating the compensation value through modeling that
reflects the ELVDD coupling characteristics. The calculation is
applied to find the exact amount of data transition and is
controlled by the position of the pixel and the data coupling
period. The experimental results show that the proposed method
reduces the crosstalk artifact of the horizontal line luminance
deviation from 11% to 2%.
