Abstract

A mobile terminal is disclosed, which enables a user to change and view a 2D image and/or a 3D image on a display unit by changing a view angle without manipulation of an input unit. The present invention includes a display panel configured to display a plurality of output images, a multi-view angle panel provided in front of the display panel to provide a user with a prescribed one of a plurality of the output images in accordance with a plurality of preset view angles, and a controller partitioning the display panel into a plurality of display regions, the controller partitioning a plurality of the output images into a plurality of partitioned images to correspond to the number of a plurality of the display regions, the controller controlling the display panel to display a plurality of the partitioned images on a plurality of the display regions.

First claim

What is claimed is:

1. A mobile terminal comprising:
a display panel configured to display a plurality of output images, the plurality of output images comprising a 3D (3-dimensional) image including a plurality of left eye images and a plurality of right eye images;
a multi-view angle panel positioned over the display panel and configured to permit viewing of one of the plurality of output images according to a selected one of a plurality of preset view angles;
a 3D image supply panel positioned over the display panel to provide the left eye image to a left eye and the right eye image to a right eye of the user; and
a controller configured to:
partition the plurality of output images into a plurality of partitioned images in a landscape direction of the plurality of output images;
partition the display panel into a plurality of grid display regions in the landscape direction to correspond to the plurality of the partitioned images and in a vertical direction to correspond to the plurality of left eye images and the plurality of right eye images;
control the display panel to display the plurality of partitioned images on the plurality of grid display regions alternately in the vertical direction such that a portion of the plurality of partitioned images is displayed on a corresponding portion of the plurality of grid display regions; and
control the display panel to display the plurality of left eye images and the plurality of right eye images on the plurality of grid display regions alternately in the landscape direction such that a portion of the plurality of left eye images and a portion of the plurality of right eye images are displayed on corresponding portions of the plurality of grid display regions.

2. The mobile terminal of claim 1 , wherein the controller is further configured to cause displaying of the plurality of partitioned images on the plurality of grid display regions alternately and sequentially to display the plurality of partitioned images on the display panel with a preset pitch which corresponds to a number of the plurality of output images.

3. The mobile terminal of claim 1 , wherein the multi-view angle panel comprises a first lenticular panel having a plurality of cylindrical lenticules configured to correspond to the plurality of preset view angles.

4. The mobile terminal of claim 3 , wherein the plurality of cylindrical lenticules are further configured to correspond to the plurality of preset view angles in a landscape direction for the plurality of output images.

5. The mobile terminal of claim 1 , wherein the multi-view angle panel comprises a microlens panel having a plurality of hemispherical microlenses configured to correspond to the plurality of preset view angles.

6. The mobile terminal of claim 1 , wherein:
the plurality of output images comprise a first output image and a second output image configured to display a same content; and
the controller is further configured to control the display panel to display the first output image and the second output image such that the second image is upside down image of the first image.

7. The mobile terminal of claim 1 , wherein the 3D image supply panel comprises a barrier panel having a plurality of light cutoff parts and a plurality of light-transmitting parts, each one of the plurality of light transmitting parts alternating with each one of the plurality of light cutoff parts.

8. The mobile terminal of claim 7 , wherein the barrier panel comprises a transparent organic light emitting diode panel.

9. The mobile terminal of claim 7 , wherein:
the barrier panel comprises a plurality of sub pixels; and
a size of each of the plurality of sub pixels is smaller than a size of a unit pixel of the left or right eye image on the display panel.

10. The mobile terminal of claim 7 , further comprising polarized glasses configured to provide the left eye image to the left eye and the right eye image to the right eye.

11. The mobile terminal of claim 1 , wherein the 3D image supply panel comprises a second lenticular panel having a plurality of cylindrical lenticules formed in a portrait direction for the plurality of output images.

12. The mobile terminal of claim 1 , further comprising shutter glasses having:
a right eye glass for light cutoff while displaying the left eye image on the display panel; and
a left eye glass for light cutoff while displaying the right eye image on the display panel.

13. The mobile terminal of claim 1 , further comprising a view angle sensing unit configured to sense a user's viewing angle.

14. The mobile terminal of claim 13 , wherein the view angle sensing unit comprises a gyro sensor or at least one camera.

15. The mobile terminal of claim 14 , further comprising a touch panel positioned over the display panel, wherein the controller is further configured to:
determine an input viewing angle corresponding to the user's viewing angle sensed by the view angle sensing unit among the plurality of preset view angles; and
change a location of an input region on the touch panel according to the determined input viewing angle such that a user input is receivable at the input region re-located.
