Large format emissive display
View Patent ↗A backframe may be utilized to align a plurality of emissive display tiles precisely with respect to one another. The individual display tiles may be removable from the backframe for replacement or other reasons. As a result, the spacing between individual tiles in an overall large format display may be precisely controlled in some cases. In addition, regularly occurring gaps between adjacent tiles may be filled with a suitable light absorbing material to reduce the visibility of seams.
1. A method comprising:
forming a display device having a plurality of spaced, light emitting cells;
coating the device with a matrix of light absorbing material;
forming said spaced light emitting cells on one side of a transparent layer;
coating a second side of said transparent layer with said absorbing material; and
coating said transparent layer at locations overlying the regions between spaced, light emitting cells with first stripes of black material of a first width, coating the regions between the edge displays of the devices and the light emitting cells with a black second stripe of a smaller width, and joining display devices together so that said second stripes have a combined width approximately equal to the width of said first stripes.
