Keywords:Viewing Angle Controllable, RGBW CF, Contrast ratio

This paper researched a viewing angle controllable FFS-LCD with RGBW CF, the measurement results show good anti-peep effect and low contrast ratio. Compared with conventional device and by analyzed the root causes of light leakage, we propose some methods to improve contrast ratio.
