Abstract: An electronic device may include a display with a waveguide and a surface relief grating (SRG) on the waveguide. The SRG may direct image light towards an eye box. An optical blocker may at least partially overlap the SRG. The blocker may include a first optical wedge having a curved surface and a second optical wedge separated from the curved surface by an air gap or a low refractive index material. The curved surface may have a freeform shape that configures the first optical wedge to propagate world light incident upon the blocker within a selected range of incident angles away from the SRG via total internal reflection. The blocker may transmit world light at other incident angles to the eye box through the waveguide. This may allow the blocker to block high incident angle world light from reaching the SRG and producing unsightly rainbow artifacts at the eye box.
