Scan line refresh for modular display systems

A display system comprising

• an array of display devices operable to provide image content, wherein a full resolution of the image content is divided among the displays;
• and
• a controller in electronic communication with the array of display devices, wherein the controller is programmed to:
• update a first display device of the array of display devices in a first update direction, wherein the first display device is updated beginning at a first scan line, l1,1, and ending at an nth scan line, l1,n, of the first display device;
• and
• update a second display device of the array of display devices in a second update direction opposite the first update direction, the second display device is updated beginning at a first scan line, l2,1, and ending at an nth scan line, l2,n, of the second display device;
• and
• wherein the first and second display devices are adjacent to each other and form a seam therebetween.

A controller programmed for scanning an array of display devices with image content, wherein a full resolution of the image content is divided among the displays, the controller configured to:

• update a first display device of the array of display devices in a first update direction, wherein the first display device is updated beginning at a first scan line, l1,1, and ending at an nth scan line, l1,n, of the first display device;
• and
• update a second display device of the array of display devices in a second update direction opposite the first update direction, the second display device is updated beginning at a first scan line, l2,1, and ending at an nth scan line, l2,n, of the second display device;
• and
• wherein the first and second display devices are adjacent to each other and form a seam therebetween.

A method of scanning a light field display system, the system comprising a plurality of groups of light field units, wherein the light field units are each configured to project light along a plurality of light propagation paths, each light propagation path having a set of two spatial coordinates and two angular coordinates in a first four-dimensional coordinate system, the two spatial coordinates defined by the position of the respective light field unit;

• the method comprising:
• updating a first group of light field units in a first update direction;
• and
• updating a second group of the light field units in a second update direction opposite the first update direction;
• and
• wherein the first and second groups of light field units are adjacent to each other and form a boundary therebetween.
