Samsung patents display cooling system for large LED screens

Samsung describes a display panel made of many small LED modules arranged in a grid. Each module has its own heat sink, and a larger heat spreader connects them all to move heat away from the screen's back.

Why it mattersThis design helps prevent large LED displays from overheating, which can extend the lifespan of the screen and maintain image quality.

In the filing’s own words

According to the present inventive concept, a display device includes a display panel in which a plurality of display modules are horizontally aligned in an M*N matrix, wherein each of the plurality of display modules includes: a mounting surface on which a plurality of inorganic light-emitting elements are mounted; a substrate including a back surface disposed opposite to the mounting surface; and a module heat-dissipation member in contact with the back surface of the substrate to dissipate heat generated in the substrate, wherein the display panel includes a panel heat-dissipation member which connects the respective module heat-dissipation members so as to dissipate heat between the respective module heat-dissipation members of the plurality of display modules.

What exactly they claim (claim 1)

1. A display device comprising: a display panel comprising a plurality of display modules arranged in parallel with each other in a M*N matrix form, wherein each of the plurality of display modules comprises: a substrate comprising a mounting surface on which a plurality of inorganic light emitting diodes are mounted and a rear surface arranged on a side opposite of the mounting surface, and a module heat dissipation member in contact with the rear surface of the substrate to dissipate heat generated from the substrate, wherein the module heat dissipation member comprises four edges corresponding to four edges of the substrate, wherein the display panel further comprises a panel heat dissipation member connecting the module heat dissipation members of the plurality of display modules to dissipate heat from the module heat dissipation members of the plurality of display modules, wherein the panel heat dissipation member is formed to extend along the four edges of each of adjacent module heat dissipation members and to contact and connect the adjacent module heat dissipation members, wherein the display device further comprises a frame to support the plurality of display modules such that the plurality of display modules are arranged in parallel with each other in the M*N matrix form, and wherein a rear surface of the panel heat dissipation member is in contact with the frame at each edge of the four edges of each substrate.
