Background technology
Along with the development of the basic studies such as Liquid Crystal, electronics, optics, materialogy, increasing lcd technology is developed.As traditional liquid crystal display mode, all need polaroid, such light utilization efficiency will reduce greatly.In order to address this problem, polymer/liquid crystal composite membrane, as a kind of lcd technology not needing polaroid proposed the earliest, is more and more subject to concern and the attention of research staff.As a rule, polymer/liquid crystal composite membrane comprises Polymer Dispersed Liquid Crystal (polymerdispersedliquidcrystal, PDLC) and polymer network liquid crystal (polymernetworkliquidcrystal, PNLC) two kinds.
At 20th century the mid-80, the people such as J.L.Fergason and J.W.Doane propose PDLC display mode, but PDLC exists the comparatively large problem such as (between 20 volts to 30 volts), narrow viewing angle of operating voltage, and therefore power consumption is larger.In addition, the molecule of Polymer Dispersed Liquid Crystal is comparatively large, is not easy to utilize horizontal component of electric field to be driven.Therefore, people are by increasing liquid crystal proportion in the mixture (proportion of usual liquid crystal arrives more than 80%), in phase separation, liquid crystal is no longer with droplet form dispersion in the polymer, but exist with a kind of continuous phase form, now polymkeric substance is then distributed in liquid crystal with network textile, that is, PNLC display mode.In PNLC liquid crystal indicator, if when subtend substrate electrode does not separately apply voltage (zero electric field), because liquid crystal is exist with a kind of multidomain state form in a network, the director distribution on each liquid crystal farmland is random, incident light causes scattering in the interface on farmland and farmland due to the discontinuous change of refractive index, shows as light tight; After adding voltage to PNLC, electric field makes the director in all liquid crystal farmlands be arranged in a single domain state along direction of an electric field, concerning the medium incident light being exactly a refractive index homogeneity, and thus printing opacity.When the voltage that PNLC applies is enough large, vertical transmitance will reach maximum, be clear state.
In transoid (reversemode) PNLC, the degree of photopolymerizable monomer is less than 10%, and its display mode principle is just contrary with the mode of operation of above-mentioned PNLC.Such as, when zero electric field, homeotropic alignment layer by the orientation of negative type liquid crystal molecule be long axis direction perpendicular to electrode, this time only sees the refractive index of minor axis axis, and with the refractive index close of polymkeric substance, be therefore clear state; When applying vertical electric field, liquid crystal molecule overturns to perpendicular to orientation substrate by electric field action, that is, the minor axis of liquid crystal molecule is toward the rotation of field parallel direction, and therefore liquid crystal lies low trend.But due to non-orientation, the direction general that liquid crystal falls down is unordered in a jumble and uncontrollable, is shown as scattering states.In addition, the mixed and disorderly degree of liquid crystal can be different because of the difference of process conditions, temperature, Liquid crystal pour pressure etc. all may impact it, and then when causing the voltage driven of different sample room, the scope difference to some extent of mist degree (haze), finally makes the mist degree of different liquid crystal inconsistent.

Embodiment
The technology contents disclosed to make the application is more detailed and complete, and can refer to accompanying drawing and following various specific embodiment of the present invention, mark identical in accompanying drawing represents same or analogous assembly.But those of ordinary skill in the art should be appreciated that hereinafter provided embodiment is not used for limiting the scope that contains of the present invention.In addition, accompanying drawing, only for being schematically illustrated, is not drawn according to its life size.
With reference to the accompanying drawings, the embodiment of various aspects of the present invention is described in further detail.
View when Figure 1A illustrates that a kind of PNLC liquid crystal indicator of the prior art does not apply vertical electric field.The liquid crystal molecule that Figure 1B illustrates in the PNLC liquid crystal indicator of Figure 1A is in constitutional diagram time clear state (transparentstate).
With reference to Figure 1A, existing PNLC liquid crystal indicator comprises a colored optical filtering substrates (colorfiltersubstrate), array basal plate (arraysubstrate) and a polymer network liquid crystal layer LC1.Wherein, polymer network liquid crystal layer LC1 is held between colored optical filtering substrates and array base palte.
Particularly, colored optical filtering substrates comprises first substrate 100,1 first electrode 102 and one first both alignment layers 104.First electrode 102 is positioned at the lower surface of first substrate 100.First both alignment layers 104 coats the surface of the first electrode 102.Array base palte and colored optical filtering substrates are oppositely arranged, and it comprises second substrate 200,1 second electrode 202 and one second both alignment layers 204.Second electrode 202 is positioned at the upper surface of second substrate 200.Second both alignment layers 204 coats the surface of the second electrode 202.As previously mentioned, when not applying driving voltage (that is, zero electric field), minus (negativetype) liquid crystal alignment is that long axis direction is perpendicular to the first electrode 102 and the second electrode 202 by both alignment layers.Now, light only sees the refractive index of minor axis axis, and with the refractive index close of polymkeric substance, be clear state.As shown in Figure 1B, when clear state, liquid crystal molecule LC1 is proper alignment in xy plane (such as, perpendicular to the horizontal plane of vertical direction).
View when Fig. 2 A illustrates that the PNLC liquid crystal indicator of Figure 1A is applied with vertical electric field.The liquid crystal molecule that Fig. 2 B illustrates in the PNLC liquid crystal indicator of Fig. 2 A is in constitutional diagram time scattering states (scatteringstate).Fig. 2 C and Fig. 2 D illustrates the haze differential schematic diagram of different display panels of the prior art respectively.
With reference to Fig. 2 A, when applying a voltage to the first electrode 102 and the second electrode 202 and creating voltage difference (namely between two electrodes, form vertical electric field) time, liquid crystal molecule LC1 is subject to the effect of vertical electric field thus overturns to perpendicular to orientation substrate (or being called horizontal direction), now the minor axis of liquid crystal molecule LC1 rotates toward field parallel direction, and therefore liquid crystal lies low trend.But due to non-orientation, the direction general that liquid crystal falls down is unordered in a jumble and uncontrollable, is shown as scattering states (as shown in Figure 2 B).In addition, the mixed and disorderly degree of liquid crystal molecule can be different because of the difference of process conditions, temperature, Liquid crystal pour pressure etc. all may impact it, such as, in fig. 2 c, the liquid crystal molecule LC2 of liquid crystal panel P1 is comparatively irregular, and thus the mist degree (haze) of liquid crystal panel P1 is relatively high.But in figure 2d, the liquid crystal molecule LC3 of liquid crystal panel P2 is comparatively neat in xy planar alignment, then the mist degree of liquid crystal panel P2 is relatively low.Thus, because mixed and disorderly degree when liquid crystal molecule lies low is uncontrollable, make the mist degree of different liquid crystal P1 and P2 inconsistent.
In order to solve the problems referred to above of prior art, PNLC liquid crystal indicator of the present invention adopts three electrodes (tri-electrode) framework.Wherein, colored optical filtering substrates side only arranges single electrode, and array base palte side changes into and arranges two electrode layers, and carries out electrical isolation through an insulation course between Different electrodes layer.When two electrodes of array base palte side exist voltage difference, the horizontal component of electric field produced by this voltage difference makes liquid crystal more trend towards irregular lying low, to eliminate the inconsistent puzzlement of mist degree in panel.
The PNLC liquid crystal indicator that Fig. 3 A illustrates according to one embodiment of the present invention does not apply view during vertical electric field.View when Fig. 3 B illustrates that the PNLC liquid crystal indicator of Fig. 3 A is applied with horizontal component of electric field.
With reference to Fig. 3 A, in this embodiment, PNLC liquid crystal indicator of the present invention comprises a colored optical filtering substrates (colorfiltersubstrate), array basal plate (arraysubstrate) and a polymer network liquid crystal layer LC4.Wherein, polymer network liquid crystal layer LC4 is held between colored optical filtering substrates and array base palte.In the present invention, polymer network liquid crystal layer LC4 is made up of eurymeric (positivetype) liquid crystal molecule.Compared by Fig. 3 A and Figure 1A, liquid crystal indicator of the present invention is same or similar in the structure of colored optical filtering substrates side, does not repeat them here.
Array base palte and colored optical filtering substrates are oppositely arranged, and it comprises second substrate 300,1 second electrode 302, insulation course 304, the 3rd electrode 306 and one second both alignment layers 308.Specifically, the second electrode 302 is positioned at the upper surface of second substrate 300.Insulation course 304 is between the second electrode 302 and the 3rd electrode 306.3rd electrode 306 has a predetermined pattern and spaced apart in the top of insulation course 304.3rd electrode 306 and the second electrode 302 realize electrical isolation by insulation course 304.Second both alignment layers 308 coats the surface of the 3rd electrode 306.Such as, insulation course 304 can be a passivation layer (passivationlayer).
Similarly, when there is voltage difference between the first electrode 102 and the second electrode 302, the vertical electric field of generation makes positive type liquid crystal molecule L C4 carry out vertical orientation thus be in clear state.It is to be noted, the key distinction of the present invention and prior art is, array base palte side is provided with the second electrode 302 and the 3rd electrode 306, when there is voltage difference between the second electrode 302 and the 3rd electrode 306, define a horizontal component of electric field (as shown in Figure 3 B), the liquid crystal molecule made in polymer network liquid crystal layer LC4 lies low thus is in scattering states by this horizontal component of electric field.
At a specific embodiment, the first electrode 102, second electrode 302 and the 3rd electrode 306 are tin indium oxide (ITO) material.In addition, the first both alignment layers 104 and the second both alignment layers 308 are polyimide (Polyimide, PI) material.
Fig. 4 A illustrates three electrode first embodiment in the PNLC liquid crystal indicator of Fig. 3 A.
With reference to Fig. 4 A, in this embodiment, the 3rd electrode 306a is wire-type of electrode.When applying horizontal component of electric field, liquid crystal major axis can rotate along direction of an electric field in xy plane.But now liquid crystal molecule has the regularity of certain degree in xy plane, mist degree will be made relatively on the low side.
Fig. 4 B illustrates three electrode second embodiment in the PNLC liquid crystal indicator of Fig. 3 A.
With reference to Fig. 4 B, in this embodiment, the 3rd electrode 306b is symmetrical semicircular electrode, to improve liquid crystal molecule at the marshalling degree of xy plane along wire-type of electrode.In figure 4b, when applying horizontal component of electric field, liquid crystal molecule is more irregular in the arrangement of xy plane, thus can promote the mist degree of liquid crystal indicator.
Adopt liquid crystal indicator of the present invention, it is designed to three electrodes (tri-electrode) and arranges in pairs or groups the framework of eurymeric polymer network liquid crystal, colored optical filtering substrates comprises first substrate successively, be positioned at the first electrode of first substrate lower surface and coat the first both alignment layers of the first electrode surface, array base palte comprises second substrate successively, be positioned at the second electrode of second substrate upper surface, be positioned at the insulation course above the second electrode, the 3rd electrode above insulation course spaced apart and coat the second both alignment layers of the 3rd electrode surface, polymer network liquid crystal layer is held between colored optical filtering substrates and array base palte.When there is voltage difference between second electrode and the 3rd electrode of array base palte side, the horizontal component of electric field of generation makes the liquid crystal molecule in polymer network liquid crystal layer lie low thus be in scattering states; When there is voltage difference between the first electrode and the second electrode, the vertical electric field of generation makes positive type liquid crystal molecule carry out vertical orientation thus be in clear state.Compared to prior art, the present invention utilizes the second electrode of array base palte side and the 3rd interelectrode voltage difference to form horizontal component of electric field, by this horizontal component of electric field, liquid crystal is lain low brokenly, with the problem that the mist degree improving different liquid crystal is inconsistent.In addition, the 3rd electrode also can be set to symmetrical semiannular shape by the present invention, to improve the situation of positive type liquid crystal molecule in xy plane proper alignment further, thus increases the mist degree of liquid crystal panel.
Above, the specific embodiment of the present invention is described with reference to the accompanying drawings.But those skilled in the art can understand, when without departing from the spirit and scope of the present invention, various change and replacement can also be done to the specific embodiment of the present invention.These change and replace and all drop in claims of the present invention limited range.
