Neighborhood brightness matching for uniformity in a tiled display screen

A tiled display system comprising:

• a first display tile;
• a second display tile adjacent to the first display tile;
• and
• a control unit configured to control brightness levels of pixels of the second display tile based on their proximity to the first display tile in response to a threshold decrease in a brightness level of the first display tile.

A method of controlling brightness levels of a tiled display system that includes a first display tile and a second display tile that is adjacent to the first display tile, comprising:

• measuring a luminance level of the first display tile;
• determining that the brightness level of the first display tile is below a threshold level;
• and
• adjusting a brightness level of the second display tile in response to said determining.

A computer-readable storage medium comprising instructions to be executed by a computing device to cause the computing device to carry out the steps of:

• receiving a luminance level of a first display tile;
• determining that the brightness level of the first display tile is below a threshold level;
• and
• reducing a brightness level of a second display tile that is adjacent to the first display tile in response to said determining,
• wherein the brightness level of the second display tile is reduced and a new brightness level of the second display tile after the reduction is greater than the brightness level of the first display tile.
