Abstract
An electronic display device including a display unit for displaying an image and a light controller disposed in front of the display unit. The light controller includes a polarizing switch for controlling a polarizing direction using an electrical signal, and a pattern polarizer for controlling light transmission in cooperation with the polarizing switch. The polarizing switch has first and second common electrodes facing each other and a liquid crystal layer located between the first and second common electrodes. The pattern polarizer has a plurality of polarizing portions and a plurality of non-polarizing portions alternately arranged in a first direction.
Claims22
An electronic display device comprising:
- a display unit for displaying an image;
- and
- a light controller in front of the display unit,
- wherein the light controller comprises:
- a polarizing switch for controlling a polarizing direction using an electrical signal, the polarizing switch having first and second common electrodes facing each other and a liquid crystal layer between the first and second common electrodes;
- and
- a pattern polarizer for controlling light transmission in cooperation with the polarizing switch, the pattern polarizer having a plurality of polarizing portions and a plurality of non-polarizing portions alternately arranged in a first direction.
An electronic display device comprising:
- a display unit comprising front and rear substrates, a liquid crystal layer between the front and rear substrates, pixel electrodes on an inner surface of the rear substrate, a common electrode and color filters on an inner surface of the front substrate, a first polarizing plate behind the rear substrate, a second polarizing plate in front of the front substrate, and a light source behind the first polarizing plate;
- and
- a light controller between the first polarizing plate and the rear substrate,
