Display device displaying a three-dimensional image

A display device comprising:

• a display panel including a first display region and a second display region, wherein the display panel is bent in a way such that the first display region and the second display region are substantially perpendicular to each other;
• an optical module including an inclined surface, wherein the optical module reflects light emitted from the first display region on the inclined surface, and transmits light emitted from the second display region on the inclined surface;
• and
• a panel driver which drives the display panel, wherein the panel driver performs a pixel shift operation,
• wherein, when a first image displayed in the first display region is shifted in an up direction, the panel driver shifts a second image displayed in the second display region in a down direction,
• wherein, when the first image is shifted in the down direction, the panel driver shifts the second image in the up direction,
• wherein, when the first image is shifted in a left direction, the panel driver shifts the second image in the left direction, and
• wherein, when the first image is shifted in a right direction, the panel driver shifts the second image in the right direction.

A display device comprising:

• a display panel including a first display region, a second display region and a third display region, wherein the display panel is bent in a way such that the first display region and the third display region face each other and the second display region is substantially perpendicular to each of the first display region and the third display region;
• an optical module including an inclined surface, where the optical module divides light emitted from each of the first, second and third display regions and incident on the inclined surface into reflected light and transmitted light;
• and
• a panel driver which drives the display panel, wherein the panel driver performs a pixel shift operation,
• wherein, when a first image displayed in the first display region is shifted in an up direction, the panel driver shifts a second image displayed in the second display region in a down direction, and shifts a third image displayed in the third display region in the down direction,
• wherein, when the first image is shifted in the down direction, the panel driver shifts the second image in the up direction, and shifts the third image in the up direction,
• wherein, when the first image is shifted in a left direction, the panel driver shifts the second image in the left direction, and shifts the third image in the left direction, and
• wherein, when the first image is shifted in a right direction, the panel driver shifts the second image in the right direction, and shifts the third image in the right direction.

An electronic device comprising:

• a processor configured to provide input image data;
• a display panel including a first display region, and a second display region positioned at a predetermined angle with respect to the first display region;
• an optical module which reflects light emitted from the first display region, and transmits light emitted from the second display region;
• and
• a panel driver which receives the input image data from the processor, and drives the display panel based on the input image data, wherein the panel driver performs a pixel shift operation in a way such that first and second images respectively displayed in the first and second display regions are shifted in opposite directions along a first direction, and are shifted in a same direction along a second direction substantially perpendicular to the first direction.
