Display device and display system

A display system comprising:

• a display device comprising:
• a pixel unit including a first display area and a second display area;
• a controller configured to control the pixel unit to display a first image in the first display area and a second image in the second display area;
• a first polarization layer formed over the first display area and having a first polarization direction;
• and
• a second polarization layer formed over the second display area and having a second polarization direction different from the first polarization direction, wherein the second image includes a light therapy image or an image adjusted for color blindness;
• and
• a first eyeglass device comprising left and right lenses,
• wherein each of the left right lenses comprises a third polarization layer having a third polarization direction.

A display device comprising:

• a display panel including odd-numbered and even-numbered pixel lines each comprising a plurality of pixels, wherein the display panel is configured to display a first image through the odd-numbered pixel lines and a second image through the even-numbered pixel lines;
• a controller comprising an information image signal generator configured to generate a first image signal based at least in part on an input image signal received from an external device, wherein the display panel is further configured to display the first image based on the first image signal;
• a first polarization layer formed over the odd-numbered pixel lines and having a first polarization direction;
• and
• a second polarization layer formed over the even-numbered pixel lines and having a second polarization direction different from the first polarization direction, wherein the second image includes a light therapy image or an image adjusted for color blindness.
