Parasitic illumination NHD‐2.7‐12864UCY3



When I display elements that do not occupy the whole line, I will get parasitic illumination in the columns under the elements (pic.1). Changing the driver's frequency, phase time or line period time leads to change in the contrast of the glow. But, if I  retreat a few rows and display one full row, the glow under the elements will disappears and will remains above them and below the line (pic.2).

What am I doing wrong?  :-[
