Abstract
A video wall system including a first display apparatus configured to output a first portion of an image; and a second display apparatus disposed below the first display apparatus and configured to output a second portion of the image with a first predetermined time delay after the first display apparatus outputs the first portion of the image to reduce a visible step difference between the images output by the first and second display apparatuses.
Claims18
A video wall system comprising:
- a first display apparatus configured to output a first portion of an image;
- a second display apparatus disposed below the first display apparatus and configured to output a second portion of the image with a first predetermined time delay after the first display apparatus outputs the first portion of the image to reduce a visible step difference between the images output by the first and second display apparatuses;
- and
- a third display apparatus disposed below the second display apparatus and configured to output a third portion of the image with a second predetermined time delay twice that of the first predetermined time delay,
- wherein the first predetermined time delay is set according to an arrangement position of the second display apparatus with respect to the first display apparatus,
- and wherein the first display apparatus and the second display apparatus sequentially display the image from an uppermost line gate to a lowermost line gate.
A method of controlling a video wall system including a first display apparatus and a second display apparatus disposed below the first display apparatus, the method comprising:
- outputting, via the first display apparatus, a first portion of an image;
- outputting, via the second display apparatus, a second portion of the image with a first predetermined time delay after the first display apparatus outputs the first portion of the image to reduce a visible step difference between the images output by the first and second display apparatuses;
- and
- outputting, via a third display apparatus disposed below the second display apparatus, a third portion of the image with a second predetermined time delay twice that of the first predetermined time delay,
- wherein the first predetermined time delay is set according to an arrangement position of the second display apparatus with respect to the first display apparatus,
- and wherein the first display apparatus and the second display apparatus sequentially display the image from an uppermost line gate to a lowermost line gate.
