Description
Summary:The visibility of electronically controlled switchable privacy display to both primary viewers and unwanted observers (snoopers) is reviewed and a method for comparison of privacy display performance is proposed. We report results from privacy display optical stacks that employ luminance and contrast control using directional backlights, switchable retardance stacks and liquid crystal pixel bias voltage control.
