Abstract

The present invention provides a display apparatus including a display panel that displays individual images to a plurality of viewing directions on a same screen; and a display control portion that causes a first inspection image to a single viewing direction and a second inspection image to another viewing direction to be displayed on the display panel, as well as methods for inspecting and manufacturing the same. According to the present invention, it is possible to execute inspection, confirmation and adjustment of a crosstalk with ease, and reduce the man-hours of the inspection, the confirmation, and the adjustment (manufacture).

Claims

1. A display apparatus comprising:

a display panel that displays individual images to a plurality of viewing directions on a same screen; and

a display control portion that causes a first inspection image to a single viewing direction and a second inspection image to another viewing direction to be displayed on the display panel.

2. The display apparatus as claimed in claim 1, wherein when a given condition is satisfied, the display control portion causes the first inspection image and the second inspection image to be displayed on the display panel.

3. The display apparatus as claimed in claim 2, further comprising an operation portion,

wherein when preset input operation is executed to the operation portion, the display control portion determines that the given condition is satisfied.

4. The display apparatus as claimed in claim 1, wherein the first inspection image is a monochrome image, and the second inspection image is a monochrome image which is different from the first confirmation image.

5. The display apparatus as claimed in claim 4, wherein the first inspection image is a black monochrome image, and the second inspection image is a white monochrome image.

6. The display apparatus as claimed in claim 1, wherein the first inspection image is a navigation image output from a navigation apparatus, and the second inspection image is an image which is different from the navigation image.

7. The display apparatus as claimed in claim 1, wherein the first inspection image is a monochrome image, and the second inspection image is an image having a figure, which is different in color from the monochrome image, is superimposed on the monochrome image.

8. The display apparatus as claimed in claim 1, wherein the first inspection image is a monochrome image, and the second inspection image is an image in which each monochrome image of the three primary colors is sequentially changed.

9. The display apparatus as claimed in claim 1, wherein when the given condition is satisfied, the display control portion causes an inspection menu image to be displayed, and causes the first inspection image and the second inspection image to be displayed based on a selected menu.

10. A method for inspecting a display apparatus which includes a display panel displaying individual images to a plurality of viewing directions on a same screen, and a main body portion connected to the display panel, comprising the steps of:

displaying a first inspection image to a single viewing direction of the display panel and a second inspection image to another viewing direction thereof;

inspecting a display state from the single viewing direction; and

inspecting a display state from the another viewing direction.

11. A method for manufacturing a display apparatus which includes a display panel displaying individual images to a plurality of viewing directions on a same screen, and a main body portion connected to the display panel, comprising the steps of:

displaying a first confirmation image to a single viewing direction of the display panel and a second confirmation image to another viewing direction thereof;

inspecting a display state from the single viewing direction; and

inspecting a display state from the another viewing direction.

12. A method for inspecting a display panel which displays individual images to a plurality of viewing directions on a same screen, comprising the steps of:

displaying a first inspection image to a single viewing direction of the display panel and a second inspection image to another viewing direction thereof;

inspecting a display state from the single viewing direction; and

inspecting a display state from the another viewing direction.

13. A method for manufacturing a display panel which displays individual images to a plurality of viewing directions on a same screen, comprising the steps of:

displaying a first confirmation image to a single viewing direction of the display panel and a second confirmation image to another viewing direction thereof;

inspecting a display state from the single viewing direction; and

inspecting a display state from the another viewing direction.
