Researchers from the University of Michigan, trying to make OLED brighter but still efficient, discovered that a pyramid-shaped OLED lamp is more efficient than a flat panel shape. The idea is that the reflective OLEDs are emitting in the inside of the pyramid, and all the light comes out of the open base. The surface emitting light on the inside is more than four times larger than the opening at the base of the pyramid, but the whole pyramid consumes about three times less electricity than trying to achieve the same brightness with a flat panel the size of the base. In addition, the researchers found out that this device achieves a better light distribution (the “halo” effect). Read more about A pyramid-shaped OLED structure is brighter than a flat panel
