Abstract

The invention provides a display panel for displaying stereo images. The display panel includes a plurality of pixels arranged in a matrix formed by rows and columns, and a plurality of black strip patterns. A plurality of rows of pixels form a display group. Two adjacent display groups are used to display a first image and a second image, respectively. The black strip patterns are disposed to cover the regions between the two adjacent display groups.

Claims

1. A display panel for displaying a stereo image, comprising:

a plurality of pixels arranged in a matrix formed by rows and columns, wherein a plurality of rows of pixels form a display group, and two adjacent display groups are used to display a first image and a second image, respectively; and

a plurality of black strip patterns disposed at the boundaries between the two adjacent display groups,

wherein the display panel is a liquid crystal display panel and comprises;

an upper substrate comprising an inner surface and an outer surface opposite to the inner surface;

a lower substrate comprising an inner surface and an outer surface opposite to the inner surface;

a liquid crystal layer sandwiched between the inner surface of the upper substrate and the inner surface of the lower substrate;

a polarizer disposed on the outer surface of the upper substrate; and

a retardation film disposed on the polarizer, wherein the retardation film has two different phase retardation values corresponding to the two adjacent display groups,

wherein at least one black matrix is disposed at the boundary of the rows of pixels which is between the adjacent black strip patterns.

2. The display panel as claimed in claim 1, wherein the black strip patterns and the at least one black matrix are disposed on the inner surface of the upper substrate.

3. The display panel as claimed in claim 2, wherein the width of the black matrix is less than the width of the black strip pattern.

4. The display panel as claimed in claim 1, further comprising:

a quarter wave plate sandwiched between the polarizer and the retardation film,

wherein the two different phase retardation values are 0λ and

½

λ

, respectively.

5. The display panel as claimed in claim 1, further comprising:

a quarter wave plate sandwiched between the polarizer and the retardation film,

wherein the two different phase retardation values are ¼

λ and

−

¼

λ

, respectively.

6. The display panel as claimed in claim 1, wherein the black strip patterns are disposed on the retardation film and the at least one black matrix is disposed on the inner surface of the upper substrate,

wherein when viewed along a direction which is orthogonal to the outer surface of the upper substrate, some black matrixes are disposed at the boundaries of the rows of pixels which are between the adjacent black strip patterns, and the others are disposed at the boundaries of the rows of pixels corresponding to the positions of the black strip patterns.

7. The display panel as claimed in claim 6, wherein the width of the black matrix is less than the width of the black strip pattern.

8. The display panel as claimed in claim 1, wherein the areas of the two adjacent display groups covered by the black strip patterns are the same.

9. The display panel as claimed in claim 1, wherein the areas of the two adjacent display groups covered by the black strip patterns are different.

10. The display panel as claimed in claim 1, wherein a time difference between capturing the first image and the second image is less than or equal to 1/60 second.

11. The display panel as claimed in claim 1, wherein capture angles of the first image and the second image are different.

12. A display device comprising the display panel as claimed in claim 1.
