$f=\frac{2d}{\cos \mathrm{\β}}=\frac{2\mathrm{dr}}{\cos \mathrm{\θ}}---\left(1\right)$

Wherein, d is the air film thickness between the semi-transmissive film of this sub-pixel and fully reflective film, and r is the refractive index of this semi-transmissive film.For given mirasol display screen, d and r is constant.

Next, with reference to figure 2, it illustrates the schematic diagram of optical path difference difference when watching mirasol display screen from different perspectives.

As shown in Figure 2, incident light 1 is with incident angle θ ₁incide on the semi-transmissive film of this sub-pixel, incident light 2 is with incident angle θ ₂be irradiated on the semi-transmissive film of this sub-pixel.A part for incident light 1 is reflected as the first reflected light 1 ', and another part refraction occurs on semi-transmissive film also then with incident angle β ₁incide on fully reflective film.A part for incident light 2 is reflected as the first reflected light 2 ', and another part refraction occurs on semi-transmissive film also then with incident angle β ₂incide on fully reflective film.In the case, the first reflected light 1 ' of this incident light 1 and the second reflected light 1 " optical path difference be f ₁, the first reflected light 2 ' of this incident light 2 and the second reflected light 2 " optical path difference be f ₂, and optical path difference f ₁with optical path difference f ₂between discrepancy delta f defined by following formula:

θ′ ₁＜θ ₁

θ′ ₂＜θ ₂

θ′ ₂-θ′ ₁＜θ ₂-θ ₁(3)

Then, incident light 1 is to convert incident angle θ ₁' incide on the semi-transmissive film of sub-pixel, incident light 2 is with incident angle θ ₂' incide on the semi-transmissive film of sub-pixel.A part for incident light 1 is reflected and through described first optical element as the first reflected light 1 ', and refraction occurs another part on semi-transmissive film and then with incident angle β ₁' incide on fully reflective film.A part for incident light 2 is reflected and through described first optical element as the first reflected light 2 ', and refraction occurs another part on semi-transmissive film and then with incident angle β ₂' incide on fully reflective film.

${f_1}^{\′}=\frac{2d}{\cos {{\mathrm{\β}}_1}^{\′}}=\frac{2\mathrm{dr}}{\cos {{\mathrm{\θ}}_1}^{\′}}$

${f_2}^{\′}=\frac{2d}{\cos {{\mathrm{\β}}_2}^{\′}}=\frac{2\mathrm{dr}}{\cos {{\mathrm{\θ}}_2}^{\′}}$

${\mathrm{\Δf}}^{\′}={f_2}^{\′}-{f_1}^{\′}=\frac{2\mathrm{dr}}{\cos {{\mathrm{\θ}}_2}^{\′}}-\frac{2\mathrm{dr}}{\cos {{\mathrm{\θ}}_1}^{\′}}=2\mathrm{dr}(\frac{1}{\cos {{\mathrm{\θ}}_2}^{\′}}-\frac{1}{\cos {{\mathrm{\θ}}_1}^{\′}})---\left(4\right)$

In conjunction with above formula (3), can obtain:

${\mathrm{\&Delta;f}}^{\&prime;}=f_2^{\&prime;}-f_1^{\&prime;}=2\mathrm{dr}(\frac{2\mathrm{dr}}{\cos {{\mathrm{\&theta;}}_2}^{\&prime;}}-\frac{2\mathrm{dr}}{\cos {{\mathrm{\&theta;}}_1}^{\&prime;}})<2\mathrm{dr}(\frac{1}{\cos {\mathrm{\&theta;}}_2}-\frac{1}{\cos {\mathrm{\&theta;}}_1})=f_2-f_1=\mathrm{\&Delta;f}---\left(5\right)$

Therefore, when the first optical element making incident light first through having converging action is irradiated to the semi-transmissive film of sub-pixel again, difference between can reducing with the optical path difference of the incident light of different incidence angles degree incidence, thus the difference reducing that the color of beholder presented to by Mirasol screen.
