Become left circularly polarized light when 15, and there is the phase delay of 1/4 λ in left circularly polarized light, rear left is reflected by semi-transparent mirror film 16
Rounding polarised light becomes right-circularly polarized light, the phase delay that 1/4 λ occurs again when right-circularly polarized light is by liquid crystal layer 15,
Therefore there is the phase delay of 1/2 λ in light altogether, i.e., just deflected 90 ° when light reaches the first polaroid 12, and light goes out
Penetrate direction vertical with the between axlemolecules of the first polaroid 12, light is absorbed by the first polaroid 12, and now display panel 10 is carried out secretly
State shows；When the light that backlight module 20 sends becomes linearly polarized light by the second polaroid 13, linearly polarized light is by phase delay
Become right-circularly polarized light during piece 18, and there is the phase delay of 3/4 λ in right-circularly polarized light, right-circularly polarized light is by liquid crystal
There is the phase delay of 1/4 λ again during layer 15, therefore there is the phase delay of λ, the between axlemolecules of the second polaroid 13 altogether in light
Direction is orthogonal with the transmission direction of principal axis of the first polaroid 12, i.e., just deflected when light reaches the first polaroid 12
180 °, the exit direction of light is vertical with the between axlemolecules of the first polaroid 12, and light is absorbed by the first polaroid 12, now shows
Panel 10 carries out dark-state and shows.
For example, when display panel 10 carries out on state of display, liquid crystal layer 15 is in the second working condition, and exterior light is by first
First polaroid 12 is reflected back by semi-transparent mirror film 16 after polaroid 12 and liquid crystal layer 15, and from the outgoing of the first polaroid 12；The back of the body
The light that light module 20 sends by after the second polaroid 13, phase delay chip 18, semi-transparent mirror film 16 and liquid crystal layer 15 from first
The outgoing of polaroid 12.Specifically, linearly polarized light is become when exterior light is by the first polaroid 12, linearly polarized light is by liquid crystal layer
Become left-handed elliptically polarized light when 15, left-handed elliptically polarized light becomes right-handed elliptical polarization light after being reflected by semi-transparent mirror film 16,
Right-handed elliptical polarization light is saturating with the first polaroid 12 by reaching the first polaroid 12, the exit direction of light after liquid crystal layer 15
Cross axle parallel, from the outgoing of the first polaroid 12, now display panel 10 carries out on state of and shows light；When backlight module 20 sends
Light becomes linearly polarized light by the second polaroid 13, and right-circularly polarized light is become when linearly polarized light is by phase delay chip 18, and
There is the phase delay of 3/4 λ in right-circularly polarized light, phase delay change dextrorotation occurs ellipse when right-circularly polarized light is by liquid crystal layer 15
Circularly polarized light, when right-handed elliptical polarization light reaches the first polaroid 12, the transmission of the exit direction of light and the first polaroid 12
Axle is parallel, and from the outgoing of the first polaroid 12, now display panel 10 carries out on state of and shows light.

The step of with transmission display methods, includes：
As best shown in figures 3 a and 3b, reflective display is carried out using display panel 10；
The light source of backlight module 20 is closed, liquid crystal layer 15 is in the first working condition, exterior light is by the first polaroid
12 and liquid crystal layer 15 after the first polaroid 12 is reflected back by semi-transparent mirror film 16, light produces the phase delay of 1/2 λ, light quilt
First polaroid 12 absorbs, and display panel 10 carries out dark-state and shows, as shown in Figure 3 a；Specifically, when ambient light is stronger, close
The light source of backlight module 20, and not to the applied voltage of liquid crystal layer 15, liquid crystal layer 15 is in the first working condition, in liquid crystal layer 15
The long axis direction of liquid crystal molecule 152 and the angle of absorption direction of principal axis of the first polaroid 12 be 45 °, exterior light is by the first polarisation
