Samsung patents display frame that matches screen material to prevent warping
Samsung has been granted a patent for a display device that uses a multi-layer frame to support a grid of light-emitting diode modules. The frame includes a specific layer made from a material that expands and contracts at the same rate as the screen's base, ensuring the structure remains stable during temperature changes.
In the filing’s own words
A display device a plurality of display modules, each of the plurality of display modules including: a substrate having a mounting surface and a rear surface opposite the mounting surface; a plurality of inorganic light emitting diodes provided on the mounting surface of the substrate; and a frame supporting the plurality of display modules arranged in a matrix, the frame including: a first frame layer contacting the plurality of display modules and including a material having material properties similar to material properties of the substrate; a second frame layer provided behind the first frame layer, and including a metal material; and a third frame layer provided between the first frame layer and the second frame layer and bonding the first frame layer and the second frame layer.
What exactly they claim (claim 1)
1. A display device comprising: a plurality of display modules, each of the plurality of display modules comprising: a substrate having a mounting surface and a rear surface opposite the mounting surface; a plurality of inorganic light emitting diodes provided on the mounting surface of the substrate; and a frame supporting the plurality of display modules arranged in a matrix, the frame comprising: a first frame layer contacting the plurality of display modules and comprising a material having a thermal expansion coefficient corresponding to a thermal expansion coefficient of a material of the substrate; a second frame layer provided behind the first frame layer, and comprising a metal material; and a third frame layer provided between the first frame layer and the second frame layer and bonding the first frame layer and the second frame layer.
