1. An electronic device, comprising:
a light emitting panel for emitting a first light ray, wherein the first light ray has at least one corresponding position in a CIE 1931 color space; and
an optical film disposed on the light emitting panel, wherein a modulated color point of the optical film has at least one corresponding position in the CIE 1931 color space;
wherein in the CIE 1931 color space, the at least one corresponding position of the first light ray has a first coordinate (x1, y1) corresponding thereto, the at least one corresponding position of the modulated color point has a second coordinate (x2, y2) corresponding thereto, and the first coordinate (x1, y1) and the second coordinate (x2, y2) satisfy following relationships with respect to an equation of y(x)=−2.48x 2+2.52x−0.22:
when (y1−y(x1))>0, (y2−y(x2))<0, or when (y1−y(x1))<0, (y2−y(x2))>0;
0.1≤x1≤0.6; and
0.1≤x2≤0.6,
wherein the first coordinate (x1, y1) and the second coordinate (x2, y2) are located on opposite sides of the equation in the CIE 1931 color space.
