Embodiment
To make those skilled in the art more fully understand technical scheme, tie below
A kind of transparent display that accompanying drawing provides the present invention and preparation method thereof is closed to be retouched in detail
State.
Fig. 1 is a kind of structural representation for transparent display that the embodiment of the present invention one is provided,
As shown in figure 1, the transparent display includes：Light source group 6 and liquid crystal display panel, light source
Group 6 is located at the sides of liquid crystal display panel, for producing light and from the side of liquid crystal display panel
Face is incident upon in liquid crystal layer, and liquid crystal display panel includes：Array base palte 1, to box substrate 2 with
And positioned at array base palte 1 and to the liquid crystal layer between box substrate 2, liquid crystal layer includes：Nematic phase
Liquid crystal 9 and the macromolecule network 8 formed by polymerisable liquid crystal monomer.In the present invention, liquid crystal
Display panel can play a part of fiber waveguide and pixel is shown.
In the present embodiment, liquid crystal display panel be twisted nematic (Twisted Nematic,
Abbreviation TN) type liquid crystal display panel or electrically conerolled birefringence (Electrically Controlled
Birefringence, abbreviation ECB) type liquid crystal display panel.Specifically, in array base palte 1
Side is formed with first electrode 3 (pixel electrode), and second electrode 4 is formed with to the side of box substrate 2
(public electrode), first electrode 3 and second electrode 4 are formed vertically after voltage is applied in
Electric field.It should be noted that TN types liquid crystal display panel and ECB type liquid crystal display panels are
Common liquid crystal display panel in this area, concrete structure is not be described in detail herein.
Fig. 2 is schematic diagram when transmission state is presented in transparent display shown in Fig. 1, and Fig. 3 is
Schematic diagram during scattering states is presented in transparent display shown in Fig. 1, as shown in Figures 2 and 3,
When not being applied with electric field in liquid crystal display panel, the nematic liquid crystal 9 in liquid crystal layer is orientated
Unanimously, do not become during horizontal conductive at this point for its refractive index for same light beam
Change, i.e., the process that the light that light source group 6 is produced is conducted in liquid crystal along preset level direction
In will not produce scattering, the incident light in side can not be projected from the surface of liquid crystal display panel
(light can integrally show edge in array base palte 1 and to being totally reflected back and forth between box substrate 2
Preset level direction is conducted, and ensures that light can be full of between whole panel), because
Transmission state (dark-state) is presented in this liquid crystal display panel.When being applied with electric field in liquid crystal display panel
When, nematic liquid crystal 9 is influenceed by macromolecule network 8, its deflection state be not it is consistent,
Therefore occur being orientated mixed and disorderly situation as depicted, the orientation of nematic liquid crystal 9 is divided into nothing
Several small regions, but due to the anisotropy of nematic liquid crystal 9, its refractive index is in major axis side
To with had differences on short-axis direction, now its state of orientation of different zones is different, therefore light
Also different in the refractive index of different zones, in this condition, light can be scattered, i.e. light
During the light that source group 6 is produced is conducted in liquid crystal layer along preset level direction, portion
Light splitter can be projected from the surface of liquid crystal display panel, therefore scattering states are presented in liquid crystal display panel
(on state of).
Fig. 4 is the drive voltage level and pair of intensity level of liquid crystal display device in the present invention
Graph of a relation is answered, as shown in figure 4, in the present embodiment, by controlled loading in first electrode 3
On driving voltage size, be controlled so as to the scattering degree to liquid crystal display panel.
Exemplary giving includes different quality percentage (3%, 5%, 7%) in Fig. 4 in liquid crystal layer
Polymerisable liquid crystal monomer HCM or polymerisable liquid crystal monomer RM257 when, drive voltage level with
The corresponding relation figure of intensity level.
By taking HCM-3% as an example, HCM-3% refers in filling liquid crystal layer in Fig. 4, in liquid crystal layer
Polymerisable liquid crystal monomer HCM mass percent be 3%, correspondingly after curing process,
Quality percentage of the macromolecule network 8 aggregated into by polymerisable liquid crystal monomer HCM in liquid crystal layer
Than for 3%.
From fig. 4, it can be seen that in the type of polymerisable liquid crystal monomer and shared matter in liquid crystal layer
On the premise of amount percentage is fixed, drive voltage level is higher, then the also higher (liquid of intensity level
Crystal device is brighter).For same polymerisable liquid crystal monomer, it is shared in liquid crystal layer
Mass percent it is higher, then correspond to same drive voltage level when corresponding intensity level also get over
It is high.
, can be by improving driving voltage and/or improving polymerisable liquid crystal from the above
The mass percent of monomer, to improve intensity level.However, found in practical operation, when
When the polymerisable liquid crystal monomer of filling is excessive, the macromolecule network 8 after solidification in liquid crystal layer is excessively
It is intensive, the deflection of nematic liquid crystal 9 is influenceed, causes driving voltage is too high, power consumption is larger to ask
Topic.Based on above-mentioned consideration, it is preferable that the mass percent of macromolecule network 8 in liquid crystal layer
Scope be 0.5%~10% (in filling liquid crystal, the matter of the polymerisable liquid crystal monomer in liquid crystal layer
Measure the scope of percentage for 0.5%~10%) when, can now have ensureing liquid crystal display panel
While preferable dispersion effect, moreover it is possible to effectively reduce driving voltage.
In the present embodiment, to ensure that light can be in liquid crystal layer along the progress of preset level direction
Conduction, need to make it that the differently- oriented directivity of liquid crystal is vertical with light conduction direction.Alternatively, array base
Plate 1 and to being provided with alignment films 5 on the opposite face of box substrate 2, alignment films 5 have default
Differently- oriented directivity, the light that light source group 6 is projected is passed in liquid crystal layer along preset level direction
Lead, preset differently- oriented directivity vertical with preset level direction.
Specifically, if preset level direction is horizontal direction X (Fig. 2 and Fig. 3 in accompanying drawing
Shown situation), then the corresponding default differently- oriented directivity of alignment films 5 is necessary for horizontal direction Y or perpendicular
Nogata is to Z；If the horizontal direction Y in accompanying drawing is in preset level direction, (such a situation is not provided
Respective drawings), then the corresponding default differently- oriented directivity of alignment films 5 is necessary for horizontal direction X or perpendicular
Nogata is to Z.From the above, when alignment films 5 is horizontal alignments, then light source group 6
It must be positioned at the side parallel with the differently- oriented directivity of alignment films 5 of liquid crystal display panel；When taking
To film 5 for when being vertically oriented, then light source group 6 can be located at any side of liquid crystal display panel.
Further, when alignment films 5 is horizontal alignments, the nematic phase when not applying electric field
The original state of liquid crystal 9 is horizontality, and nematic liquid crystal 9 is needed after applying an electric field toward vertically
State polarization, to meet the demand, then nematic liquid crystal 9 need to use positivity liquid crystal；When taking
To film 5 for when being vertically oriented, when not applying electric field, the original state of nematic liquid crystal 9 is vertical
State, needs nematic liquid crystal 9 to be polarized toward horizontality after applying an electric field, above-mentioned to meet
Demand, then nematic liquid crystal 9 need to use negative liquid crystal.
Foregoing teachings elaborate that liquid crystal display panel realizes the corresponding construction and work of fiber waveguide effect
Make principle, will realize that structure and principle that pixel is shown are carried out in detail to liquid crystal display panel below
