Abstract

There are obvious moiré fringes in the naked-eye 3D images light-emitting diode(LED) display based on a conventional lenticular lens grating. To weak moiré fringes, we proposed 1D unequal distance metagrating inclined to the display. Based on convolution with superposition of intensity profile which is transmitted from the metagrating and bidirectional array pixels of display and the spread function, firstly, we simulate moiré fringes on unequal distance and inclined metagraing with display respectively, meanwhile, main moiré pitch were extract from moiré fringes. Comparison with conventional lenticular lens grating shows that the slanted metagrating could make moiré fringes sparsely, and the unequal distance metagrating make the moiré fringes intensity contrast ratio weaken. The above combination of slant and unequal distance can achieve the purpose of weakening the moiré fringes and crosstalk also reduced simultaneously.
