1. A light field display device, comprising:
a backlight layer;
a light control array layer;
a control layer; and
a processing unit; wherein the backlight layer, the light control array layer, and the control layer are arranged side by side, and images on the backlight layer, the light control array layer, and the control layer are superimposed to form a three-dimensional image,
wherein the processing unit obtains a luminous intensity of the backlight layer, an attenuation rate of the light control array layer, and an attenuation rate of the control layer through the following formula:
![]() wherein i=1, 2, or 3 respectively represents red, green, or blue, L(oj,sj) represents that a viewer receives light from any object point on a three-dimensional object, I(x0,y0) represents the luminous intensity of the backlight layer, fN(xN,yN) represents the attenuation rate of the light control array layer, and g(xN+1,yN+1,i) represents the attenuation rate of a sub-pixel of a pixel unit with a color of i of the control layer.
