Stereoscopic image display and alignment method thereof

A 3D filter comprising:

• a first area having a plurality of even numbered and odd numbered alternating lines, each line having an equal height;
• the even numbered lines formed with a first polarization characteristic;
• a first dummy line formed outside of the first area and adjacent to a first line of the 3D filter, the first dummy line having a height greater than a height of a single line;
• the odd numbered lines formed with a second polarization characteristic;
• a second dummy line formed outside of the first area and adjacent to a last line of the 3D filter, the second dummy line having a height greater than the height of a single line;
• the first dummy line formed with a polarization characteristic opposite to a polarization characteristic of a first line in the first area;
• and
• the second dummy line formed with a polarization characteristic opposite to a polarization characteristic of a last line in the first area.

A stereoscopic image display alignment system, comprising:

• a display panel;
• a plurality of display alignment marks disposed along a first edge and a second edge of the display panel, respectively, the first edge being opposite to the second edge, wherein two of the plurality of display alignment marks are disposed at a midpoint along opposite side edges of the display panel;
• a 3D filter disposed in planar relation to the display panel;
• a plurality of filter alignment indicia portions disposed on the 3D filter;
• a movable platform configured to support and move the panel display;
• a controller adapted to control movement of the movable platform;
• a plurality of sensors configured to sense misalignment between the display alignment marks and the filter alignment indicia portions;
• and
• a controller configured to receive signals from the sensors corresponding to an amount of sensed misalignment, and controlling the movable platform to move the display panel to minimize the misalignment.

An alignment method of a stereoscopic image display device comprising:

• aligning the 3D filter with the display panel such that at least two of a plurality of display alignment marks of the display panel overlap at least two a plurality of filter alignment indicia portions of the 3D filter;
• sensing misalignment between the display alignment marks and the filter alignment indicia portions;
• and
• moving the display panel to minimize the misalignment based on tan amount of sensed misalignment,
• wherein the plurality of display alignment marks disposed along a first edge and a second edge of the display panel, respectively, the first edge being opposite to the second edge, wherein two of the plurality of display alignment marks are disposed at a midpoint along opposite side edges of the display panel.
