Screen privacy devices with alternating polymer-dispersed liquid crystal bands

A method, comprising:

• applying a first polymerizing treatment to a polymer-dispersed liquid crystal (PDLC) compound;
• applying a mask to alternating bands of the PDLC compound;
• and
• applying a second polymerizing treatment to un-masked PDLC compound to form alternating bands of the PDLC compound, the alternating bands having different light-scattering properties.

A display device comprising:

• a screen to generate a visual output;
• a screen privacy device disposed over the screen, the screen privacy device comprising a polymer-dispersed liquid crystal (PDLC) compound being divided into alternate bands, wherein adjacent bands have, when a voltage is applied, different light-scattering properties;
• a pair of electrodes disposed on opposites surfaces of the PDLC compound to selectively apply a voltage potential across the PDLC compound;
• and
• a controller to pass a voltage to the pair of electrodes to selectively switch the PDLC compound between a first mode and a second mode.
