Abstract
A method of forming a light modulating signal for displaying a 3D includes preparing a plurality of data sets for 2D image data with different viewpoints; imposing a phase value the plurality of data sets, by which each of the 2D images is seen at a corresponding viewpoint; and superposing the 2D images.

A method of forming a light modulating signal for displaying a three-dimensional (3D) image, the method comprising:
- preparing a plurality of data sets corresponding to two-dimensional (2D) images with different viewpoints;
- determining a phase value with respect to each of the 2D images, by which each of the 2D images is seen at a corresponding viewpoint;
- imposing the determined phase value to the plurality of data sets, and superposing the plurality of data sets on which the phase value has been imposed;
- and
- converting a complex function value obtained from the superposing into an operating signal for a space light modulator.

A method of forming a light modulating signal for displaying a three-dimensional (3D) image, the method comprising:
- preparing a plurality of data sets corresponding to two-dimensional (2D) images with different depth cues;
- imposing a phase value to each of the plurality of data sets, by which each of the 2D images is seen at a certain position in a viewer's pupil, of a plurality of positions;
- determining a conversion function by which the 2D images are provided at the plurality of positions in the viewer's pupil;
- applying the conversion function to the plurality of data sets;
- superposing the plurality of data sets to which the conversion function has been applied;
- and
- converting a complex function value obtained from the superposing into an operating signal for a space light modulator.

A method comprising:
- obtaining data sets corresponding to two-dimensional (2D) images having different viewpoints in eyes of a viewer;
- determining phase values for the 2D images, by which each of the 2D images is seen at a corresponding viewpoint in the eyes of the viewer;
- applying the determined phase values to the data sets, respectively;
- calculating a complex function value by superposing the data sets to which the phase values have been applied;
- converting the calculated complex function value into an operating signal for a space light modulator;
- modulating light emitted from a backlight unit based on the operating signal;
- and
- displaying the 2D images directed to the different viewpoints in the eyes of the viewer by using the modulated light, thereby performing a display of a three-dimensional image as seen by the viewer.
