Abstract:
A switchable view angle control device for a privacy view display system includes an electrically switchable view angle control LCD that is operable in a first state and a second state; a front polarizer located on a viewing side of the switchable view angle control LCD; and a polarized light source located on a non-viewing side of the switchable view angle control LCD that emits polarized light. When the switchable view angle control LCD in the first state, the view angle control device operates in a narrow angle view mode in which off-axis polarized light from the polarized light source is changed by the switchable view angle control LCD so that the off-axis light is absorbed by the front polarizer, and on-axis light passes through the switchable view angle control LCD and the front polarizer. When the switchable view angle control LCD is in the second state, the view angle control device operates in a wide angle view mode in which the polarized light from the polarized light source is scattered by the switchable view angle control LCD and passes through the front polarizer.

Claim (Index 20):
The display system of  claim 11 , wherein the switchable view angle control LCD includes a hybrid aligned nematic (HAN) liquid crystal cell between a first substrate and a second substrate, and in the first state an alignment layer of the liquid crystal molecules on the first substrate is a vertical alignment layer and an alignment layer of the liquid crystal molecules on the second substrate is a planar alignment layer; and\n the vertical alignment layer has a pretilt in a direction not parallel to the planar alignment layer.
