  • Display device and method for reducing moiré effects using the same
    Patent number: 9671609
    Abstract: A display device includes a printed circuit board (PCB) having a plurality of light emitting members, an anti-moiré member spaced away from the plurality of light emitting members at about a first distance (d), and a frame member receiving the PCB such that the PCB is interposed between the anti-moiré and the frame member. The anti-moiré member includes a first layer disposed to face the PCB and having a first foil with a randomized pattern surface. The first distance (d) equals L/(2*tan (?)). The second distance (L) is a shortest distance between two adjacent light emitting members. Each of the array of light emitting members has a radiation angle ?.
