Optimal design of omni-directional viewing angle switching panel.
A viewing angle switching (VAS) panel used for the conversion of wide and narrow viewing angle has been demonstrated. Unlike the previous VAS panels, this one features a pair of same-handed circular polarizers and it is capable of switching the viewing angle omni-directionally from wide to narrow or vice versa by electrically controlling the birefringence effect of the LC layer which is sandwiched in between. To explain how it works, the design principle as well as the optimization of both wide and narrow viewing modes will be elaborated hereinafter.
