Stereoscopic image display device and electronic device with the same

A method of driving a stereoscopic image display device having a light controller, the light controller including,

• a first substrate;
• a surface electrode formed on a substantially entire surface of the first substrate;
• a second substrate;
• branch type electrodes, each having a parent electrode portion arranged along one direction of the second substrate and plural branched electrode portions formed by branching off from the parent electrode portion, the branch type electrodes being arranged as multiple layers on the second substrate that are insulated from each other;
• and
• liquid crystal disposed between the first substrate and the second substrate;
• wherein the branched electrode portions of the branch type electrodes are arranged to cross over each other,
• the method comprising:
• in a first mode when the light controller is in a predetermined position,
• applying a reference voltage to the surface electrode;
• selecting one branch type electrode of the branch type electrodes;
• and applying a data voltage thereto to split an image into a left eye image and a right eye image;
• and
• in a second mode when the light controller is rotated from the predetermined position to another position,
• applying a reference voltage to the surface electrode;
• selecting another branch type electrode of the branch type electrodes;
• and applying a data voltage thereto to split an image into a left eye image and a right eye image.

A stereoscopic image display device, comprising:

• an imager for realizing an image;
• and
• a liquid crystal barrier for splitting the image into a left eye image and a right eye image to provide the left eye and right eye images, respectively, to the left eye and the right eye of a user,
• wherein the liquid crystal barrier includes,
• a first substrate;
• a surface electrode formed on a substantially entire surface of the first substrate;
• a second substrate;
• branch type electrodes, each having a parent electrode portion arranged along one direction of the second substrate and plural branched electrode portions formed by branching off from the parent electrode portion, the branch type electrodes being arranged as multiple layers on the second substrate that are insulated from each other;
• and
• liquid crystal disposed between the first substrate and the second substrate,
• wherein the branched electrode portions of the branch type electrodes are arranged to cross over each other.
