In an implementation, each tile has a portion of a clamp that joins with another portion of the clamp on another tile. A tile is removed from the display by unlocking the clamp portions. The tile is removed without affecting the position of the other tiles in the display. ## Claims ### Claim 1 A system comprising: a first light-emitting tile comprising a plurality of light emitting diodes and a first connecting member positioned adjacent to a first edge of the first light-emitting tile; and a second light-emitting tile comprising a plurality of light emitting diodes and a second connecting member positioned adjacent to a second edge of the second light-emitting tile, wherein the first light-emitting tile and the second light-emitting tile are coupled together by the first connecting member coupling with the second connecting member so a side of the first light-emitting tile abuts a side of the second light-emitting tile. ### Claim 2 (depends on 1) The system of claim 1 wherein the first light-emitting tile can be decoupled from the second light-emitting tile while the second light-emitting tile remains coupled to any light-emitting tiles the second light-emitting tile was coupled to other than the first light-emitting tile. ### Claim 3 (depends on 1) The system of claim 1 wherein the first connecting member comprises a hook and the second connecting member comprises a receptacle. ### Claim 4 (depends on 1) The system of claim 1 wherein the first connecting member comprises a hook coupled to a lever mechanism, and the lever mechanism comprises a safety latch that prevents the hook from releasing accidentally. ### Claim 5 (depends on 1) The system of claim 1 comprising allowing a dowel of the second connecting member to be movable from a nonretracted position to a retracted position and from the nonretracted position to the retracted position. ### Claim 6 (depends on 5) The system of claim 5 wherein when the dowel is in the nonretracted position, allowing at least a portion of the dowel to be positioned in an aperture of the first connecting member. ### Claim 7 (depends on 6) The system of claim 6 wherein when the dowel is in the retracted position, allowing the dowel not to be positioned in the aperture of the first connecting member. ### Claim 8 (depends on 5) The system of claim 5 comprising allowing a biasing element of the second connecting member to bias the dowel from the non-retracted position to the retracted position. ### Claim 9 (depends on 8) The system of claim 8 wherein the biasing element is a spring mechanism. ### Claim 10 (depends on 1) The system of claim 1 wherein the first connecting member comprises a hook coupled to a lever mechanism, and when the lever mechanism is moved from a first position to a second position, the hook moves the dowel from the retracted position to the nonretracted position such that at least a portion of the dowel is positioned in an aperture of the first connecting member. ### Claim 11 (depends on 10) The system of claim 10 wherein the hook opposes a biasing force of a biasing element that biases the dowel from the non-retracted position to the retracted position. ### Claim 12 A system comprising: a first light-emitting tile comprising a plurality of light-emitting elements disposed thereon and a first connecting member positioned adjacent to an edge thereof; a second light-emitting tile comprising a plurality of light-emitting elements disposed thereon and a second connecting member positioned adjacent to a first edge thereof and a third connecting member positioned adjacent to a second edge thereof; and a third light-emitting tile comprising a plurality of light-emitting elements disposed thereon and a fourth connecting member positioned adjacent to an edge thereof, wherein the first and second light-emitting tiles are coupled together by way of the first and second connecting members, and the second and third light-emitting tiles are coupled together by way of the third and fourth connecting members. ### Claim 13 (depends on 12) The system of claim 12 wherein the first light-emitting tile and the second light-emitting tile are coupled together by the first connecting member coupling with the second connecting member such that a side of the first light-emitting tile abuts a side of the second light-emitting tile, the second light-emitting tile and the third light-emitting tile are coupled together by the third connecting member coupling with the fourth connecting member such that a side of the second light-emitting tile abuts a side of the third light-emitting tile, and the first light-emitting tile can be decoupled from the second light-emitting tile of the while the second light-emitting tile remains coupled to the third light-emitting tile. ### Claim 14 (depends on 12) The system of claim 12 wherein the second edge is opposite of the first edge of the second light-emitting tile. ### Claim 15 (depends on 12) The system of claim 12 wherein when the first light-emitting tile is coupled the second light-emitting tile and the second light-emitting tile is coupled to the third light-emitting tile, the first light-emitting tile and the third light-emitting tile do not abut each other. ### Claim 16 (depends on 12) The system of claim 12 wherein the first connecting member comprises a hook and the second connection member comprises a receptacle. ### Claim 17 (depends on 12) The system of claim 12 wherein the first connecting member comprises a clip mechanism. ### Claim 18 (depends on 12) The system of claim 12 wherein the second connecting member comprises a retractable dowel. ### Claim 19 (depends on 12) The system of claim 12 wherein the second connecting member comprises an alignment hole. ### Claim 20 (depends on 12) The system of claim 12 wherein the first connecting member comprises a hook coupled to a lever mechanism, and the lever mechanism comprises a safety latch that prevents the hook from releasing accidentally.
