Illustrate below by several embodiments.
Embodiment one
The present embodiment provides a kind of touch display screen, and Fig. 1 is a kind of cross section structure schematic diagram of touch display screen.As Fig. 1
Shown, this touch display screen 100 includes：Opposed first substrate 101 parallel to each other and second substrate 102, are arranged on the first base
First electrode 103 between plate 101 and second substrate 102 and second electrode 104, are filled in first substrate 101 and second substrate
Liquid crystal 106 between 102, is arranged on the touch sensible electrode 107 of second substrate 101 outside or inner side.In the power-on state
Horizontal component of electric field can be produced, thus can be used for driving liquid crystal 106 between one electrode 103 and second electrode 104.Liquid crystal 106 include to
Row phase liquid crystal and the long-chain compound 105 for making described Formation of liquid crystals scattering states being dispersed in nematic liquid crystal.
For example, first substrate 101 and second substrate 102 are transparent glass substrate, plastic base etc., can divide thereon
Xing Cheng not control or drive circuit of first electrode 103 and second electrode 104 etc..For example, the folding of glass substrate and plastic base
Rate of penetrating is 1.0-1.2.
For example, in the present embodiment, first electrode 103 is slit-shaped, and second electrode 104 is slit-shaped or tabular, and it is special
Levy and be, slit-shaped electrode includes multiple being spaced and sub-electrode arranged in parallel.First electrode 103 and second electrode 104
Connect to control circuit, control circuit can apply a positive voltage in first electrode 103, second electrode 104 applies one
Negative voltage or be grounded, thus forms electric field, for example, shape in first electrode 103 and the corresponding region of second electrode 104
Become horizontal component of electric field, to drive the liquid crystal molecule in these regions to rotate in the horizontal direction.According to different designs, slit-shaped electricity
Multiple sub-electrodes in extremely can be by uniformly applied voltage it is also possible to by individually applied voltage, such as gradually rising or drop
Low, it is consequently formed the electric field gradually changing.
For example, first substrate 101 and second substrate 102 can also form oriented layer, this oriented layer is connect with liquid crystal 106
Touch, therefore by oriented layer, liquid crystal molecule can be orientated, the material of oriented layer can be for example polyimides (PI).Example
As the differently- oriented directivity being arranged on oriented layer on first substrate 101 and second substrate 102 is contrary, thus forming antiparallel orientations
Construction.
For example, the forming process of oriented layer includes：First substrate 101 and second substrate 102 are respectively coated with orientation liquid,
Carry out friction orientation technique after orientation liquid solidification, or carry out photocuring and orientation process.Oriented layer contributes to liquid crystal molecule
Deflect under electric field action.

The deflection to control liquid crystal molecule for the electric field producing between electrode.
The present embodiment is described in detail taking the liquid crystal indicator of advanced super dimension switch (ADS) pattern as a example.Senior
In the liquid crystal touch display screen of super dimension field translative mode, by electric field produced by gap electrode edge in same plane and narrow
The electric field that seam electrode layer and plate electrode interlayer produce forms multi-dimensional electric field, makes in liquid crystal cell between gap electrode, directly over electrode
All aligned liquid-crystal molecules can produce rotation, thus improve liquid crystal operating efficiency and increasing light transmission efficiency.Senior super
Dimension field switch technology can improve the picture quality of liquid crystal indicator, has high-resolution, high permeability, low-power consumption, width regard
The advantages of angle, high aperture, low aberration.
For example, as shown in figure 1, in the touch display screen 100 that the present embodiment provides, the long-chain of long-chain compound 105 hangs down
Straight in first substrate 101, that is, in long-chain compound 105 direction of long-chain with not powered under the conditions of liquid crystal 106 arragement direction one
Cause.
It should be noted that as shown in figure 1, liquid crystal molecule itself does not light, in this touch display screen near liquid crystal molecule

The lamp bar of pole pipe (LED) or be cold-cathode fluorescence lamp (CCFL).First electrode 103, second electrode 104 are not being powered up and shape
Under conditions of becoming electric field, originally as clear state, the transmitance of the light propagated in liquid crystal layer can reach more than 90% to liquid crystal layer,
But due to total reflection, these light can't be from the surface outgoing of first substrate and second substrate.Under conditions of powering up, by
In the presence of long-chain compound, liquid crystal molecule presents scattering states, changes light and is incident to first substrate or from liquid crystal layer
The incidence angle of two substrates, destroys the condition of light total reflection, can be with the first base in the respective regions some light applying electric field
Plate or second substrate have a certain degree injection, thus can be used for the display function realizing having the high grade of transparency.And, this display
Realizing not by two polaroids used in traditional liquid crystal indicator of function, be thus avoid and led using polaroid
The decline of the light light transmittance causing, thus improves display brightness, and reduces energy ezpenditure.
For example, first substrate 101 and second substrate 102 are connected to each other by sealed plastic box, constitute liquid crystal cell.Sealed plastic box is by saturating
Bright material is formed, and light can be incident to liquid crystal layer through sealed plastic box.
For example, can be mixed in liquid crystal formed long-chain compound needed for monomer and light trigger, long-chain compound by
Multiple corresponding monomers are polymerized formation under ultraviolet irradiation and in the presence of light trigger.
For example, formed the monomer needed for long-chain compound include following in any one or combination:4,4 '-two [6- (third

4 '-two [6- (acryloxy) hexyloxy] biphenyl, poly- 2- methyl isophthalic acid, 4- bis- [4- (3- acryloxy hexyloxy) benzoic acid
Base] hydroquinones, poly- 2- methyl isophthalic acid, 4- bis- [4- (3- acryloxy propoxyl group) benzoxy] hydroquinones, correspondingization
Formula is followed successively by：
For example, the polymerization degree n value in above-mentioned long-chain compound is 10-18.
For example, in the present embodiment, nematic liquid crystal refers to be in nematic liquid crystal.Nematic liquid crystal molecule is rod,
Can move in three-dimensional scope, and electrically there is obvious anisotropy, it is possible to use external electric field changes its molecule
Oriented, thus can change the optical property of liquid crystal.For example, twisted nematic (TN) liquid crystal is distortion in its natural state
, after adding electric current to this liquid crystal, they will be according to the corresponding angle of the alive size reverse twist of institute.In the present embodiment
In, the nematic liquid crystal being used is, for example, positivity liquid crystal (△ ε>0) and refractive index be 1.6-1.8 (such as 1.7).For example, nematic
Phase liquid crystal includes any one or combination in following liquid crystal molecules：
For example, in the mixture being made up of liquid crystal molecule, monomer and light trigger, the mass percentage content of monomer is
