Abstract
We demonstrated a novel viewing angle controllable display device in in-plane switching (IPS) mode with single panel. In the device, single pixel is separated into two regions, named as main pixel for displaying images and sub pixel for viewing angle control. Initially, the liquid crystal (LC) in sub pixel is homogenously aligned on substrate. For wide viewing angle mode, the LC switches in plane in the main pixel and for narrow viewing angle mode the LC switches the level of tilt angle without rotating by applying fringe electric fieldge. The proposed device is facilitated with simple manufacturing process and good viewing angle control with single panel.
