Display device and method for operating the same

A method for operating a display device, wherein the display device includes:

• a wiring substrate including a first area having a plurality of link lines and a second area having common line electrodes and divided into a plurality of blocks;
• a plurality of display parts on the wiring substrate and spaced apart from each other, each of the plurality of display parts including a first area having a plurality of light-emitting elements and a plurality of signal lines and a second area having a partitioning-wall pattern;
• and
• a transmissive solution layer disposed between the wiring substrate and each of the display parts and corresponding to the second area of the display parts, the transmissive solution layer including a plurality of electrophoretic particles,
• wherein the second area of the display parts includes a lower electrode under the partitioning-wall pattern, and
• wherein the method comprises:
• supplying a power to at least one of the common line electrode and the lower electrode of the blocks such that the plurality of electrophoretic particles migrate toward the partitioning-wall pattern so as to switch the second area of the display parts into a light-transmissive area.

A display device, comprising:

• a common line electrode;
• a lower electrode;
• a plurality of partitioning-wall pattern between the common line electrode and the lower electrode and connected the common line electrode and the lower electrode;
• and
• a transmissive solution layer disposed between the partitioning-wall pattern and including a plurality of electrophoretic particles,
• wherein the display device switches between a light-transmissive mode and a light-blocking mode by supplying voltage to at least one of the common line electrode and the lower electrode.
