Abstract

Disclosed herein is a display device, including: a display panel having a display area having a plurality of pixels each composed of one or more sub-pixels, a first image and a second image being alternately displayed adjacent to each other in the sub-pixels, the first image and the second image being displayed in visual directions different from each other so as to be adapted to be discriminated from each other; and a crosstalk correcting portion having a crosstalk correcting table, configured to carry out crosstalk correction for images different from one another by using the crosstalk correcting table; wherein the display area is divided into a plurality of areas, and gamma correction which differs so as to correspond to the plurality of areas obtained through the division, respectively, is carried out for an image as an object of the crosstalk correction.

First claim

The application is claimed as follows:

1. A display device, comprising:
display panel having a display area having a plurality of pixels that are disposed in a matrix and each are composed of one or more sub-pixels, a first image and a second image being alternately displayed adjacent to each other in the sub-pixels, the first image and the second image being displayed in visual directions different from each other so as to be adapted to be discriminated from each other; and
crosstalk correcting portion having a crosstalk correcting table, configured to carry out crosstalk correction for images different from one another by using said crosstalk correcting table,
wherein said display area is divided into a plurality of division areas,
at least one of the division areas is non-rectangular and includes a plurality of extending portions,
a shape of a border of at least one of the division areas is zigzag, and
said crosstalk correcting table is composed of a plurality of crosstalk correcting tables corresponding to said plurality of the division areas, respectively.

2. The display device according to claim 1 , wherein said crosstalk correcting portion carries out the crosstalk correction of K (K is an integral number) gradations for N 1 (N 1 is a positive integral number of smaller than N) in N (N is a positive integral number of equal to or larger than 2) frames, and carries out the crosstalk correction of the (K+1) gradations for the (N−N 1 ) frames.

3. The display device according to claim 1 , wherein said display panel includes slits of a light blocking layer with which the first image and the second image are made to be adapted to be discriminated from each other in different visual directions, respectively.

4. The display device according to claim 1 , wherein said crosstalk correcting table contains correction data corresponding to gradations of object sub-pixels each as an object of the correction, and gradations of first adjacent sub-pixels that are adjacent to the object sub-pixels.

5. The display device according to claim 1 , wherein the one pixel is composed of sub-pixels having colors different from one another, and said crosstalk correcting table contains therein data corresponding to gradations of the object sub-pixels each as an object of the correction, and gradations of second adjacent sub-pixels that are adjacent to the object sub-pixels and have the same color as the object sub-pixels.

6. The display device according to claim 4 , wherein said crosstalk correcting table has a white reference, and correction data is zero when each of the gradations of the first adjacent sub-pixels is the 63-th gradation corresponding to white.

7. The display device according to claim 5 , wherein said crosstalk correcting table has a white reference, and correction data is zero when each of the gradations of the second adjacent sub-pixels is the 63-th gradation corresponding to white.

8. The display device according to claim 4 , wherein said crosstalk correcting table has an auto-reference that refers to a state independent on other sub-pixels than the object sub-pixels, and correction data is zero when the gradations of the object sub-pixels and the first adjacent subpixels are equal.

9. The display device according to claim 5 , wherein said crosstalk correcting table has an auto-reference that refers to a state independent on other sub-pixels than the object sub-pixels, and correction data is zero when each of the gradations of the second adjacent sub-pixels is the 0-th gradation corresponding to black with no light leakage.

10. The display device according to claim 4 , wherein said crosstalk correcting table has a black reference, and correction data is zero when each of the gradations of the first adjacent sub-pixels is the 0-th gradation corresponding to black.

11. The display device according to claim 5 , wherein said crosstalk correcting table has a black reference, and the correction data is zero when each of the gradations of the second adjacent sub-pixels is the 0-th gradation corresponding to black.
