Description
Technical field
The present invention relates to adopt the lcd technology of optical compensation means, relate in particular to a kind of liquid crystal panel.
Background technology
The market of LCD shoots up, and application is constantly expanded, and the particularly application of large scale liquid crystal TV requires LCD to have broad angular field of view.The critical piece of LCD is a liquid crystal panel, and liquid crystal panel comprises the array base palte of box and color membrane substrates are provided with liquid crystal therebetween.Liquid crystal deflection under the voltage effect can be controlled the degree of deflection of liquid crystal by the control voltage swing, thereby realizes the purpose of modulation light penetration, the gray scale that promptly can the modulating liquid crystal panel be presented.
Because there is the narrow defective in visual angle in the available liquid crystal display, prior art has proposed plurality of display modes to overcome narrow visual angle defective, comprises that 90 ° of twisted nematic liquid crystals add compensate film (Twisted Nematic+film; Hereinafter to be referred as: TN+film) pattern, multidomain homeotropic alignment (Multi-domain VerticalAlignment; Hereinafter to be referred as: MVA) pattern, the graphical homeotropic alignment of pixel electrode (PatternedVertical Alignment; Hereinafter to be referred as: PVA) pattern, plane drive pattern (In-PlaneSwitching; Hereinafter to be referred as: IPS) pattern and utilize the plane of fringing field to drive (Fringe FieldSwitching; Hereinafter to be referred as: FFS) pattern etc.
Though above-mentioned display mode successively is suggested and realizes gradually industrialization, the actual use shows that still there is associated disadvantages in above-mentioned display mode.The MVA pattern need promptly be made complicated bulge-structure in color membrane substrates one side on colored filter, increased manufacturing cost; The PVA pattern need be made into pixel electrode complicated narrow slit structure, has influenced the light utilization ratio; And IPS pattern and FFS pattern require technology controlling and process precision height, so the manufacturing process difficulty is big.
The TN+film pattern is simple and convenient, and effect is obvious.From before " WV-SA " pattern carry out the transition to present " WV-EA " pattern gradually.Add compensate film and promptly on polaroid, increase one deck compensate film; for example; Figure 1 shows that a kind of wide visual angle polarizer constructions synoptic diagram that comprises compensate film in the prior art, this polaroid can comprise stripping film 10, adhesive coating 20, basalis 30, compensate film 40, polarizing coating 50, support membrane 60 and diaphragm 70 in turn.Wherein, polarizing coating 50 can adopt polyvinyl alcohol (PVA) (Polyvinyl Alcohol; Be called for short: PVA) material, compensate film 40 can adopt discotic mesogenic layer (Discotic Liquid Crystal; Hereinafter to be referred as: DLC), basalis 30 links to each other with compensate film 40, can adopt triallyl cyanurate (being called for short TAC) material.So-called compensate film claims phase shift films again, changes the light phase place of passing its transmission with its peculiar material, thereby offsets the delay of liquid crystal molecule to the light phase place, makes from the light of polaroid outgoing and reduces or eliminates phase delay, and the visual angle of LCD is enlarged.Polarizing coating, compensate film and basalis glazed thread all can be by the parallactic angle size is defined through the direction of axle.So-called to parallactic angle, promptly light sees through the angle of vertical axis of symmetry on the direction of axle and plane, liquid crystal panel place.Is example with basalis to parallactic angle, be illustrated in figure 2 as the contraposition angular dependence synoptic diagram of the basalis that links to each other with compensate film on the liquid crystal panel in the prior art, dot-and-dash line Y is vertical axis of symmetry on plane, liquid crystal panel place, line R1 has indicated the light that is positioned at the basalis on the upper polarizer to see through direction of principal axis, angle α 1 between line R1 and the dot-and-dash line Y be this basalis to parallactic angle, line R2 has indicated the light of basalis on time polaroid to see through direction of principal axis, angle α 2 be this basalis to parallactic angle.On the general same polaroid polarizing coating, compensate film and basalis parallactic angle is 45 °, promptly light sees through the direction of principal axis unanimity, and upper and lower polaroid light to see through direction of principal axis vertical mutually, as shown in Figure 2.
But at present the wide visual angle polaroid that uses makes the photoelectric characteristic curve of LCD reverse when dark attitude, is illustrated in figure 3 as the curve map of the available liquid crystal panel transmitance and the voltage that applies.So-called photoelectric characteristic curve is liquid crystal molecule to the transmitance of light and is applied to relation curve between the voltage of liquid crystal molecule both sides, the counter-rotating when dark attitude of photoelectric characteristic curve is meant when liquid crystal molecule both sides voltage increases to the light penetration that makes liquid crystal molecule and is reduced to a certain degree, the phenomenon that the light penetration of liquid crystal molecule increases on the contrary.
The influence of photoelectric characteristic curve counter-rotating is that the brightness of LCD when dark attitude is increased, and dark attitude brightness increase will cause dark attitude the time contrast descend.Contrast is meant the high-high brightness that display device can reach and the ratio of minimum brightness, the ratio of just bright attitude and dark attitude brightness.Improving at present the effective method of contrast is exactly the brightness that reduces dark attitude, and therefore, the reverse speed characterisstic of photoelectric characteristic curve has influenced the stability of contrast greatly.The main flow computing machine is generally 800～1000 with the contrast value of LCD at present: 1, and 1000: 1 above LCD demands are increasing.Can't effectively improve contrast and the stable meeting the market requirement that is difficult to thereof.Thereby generally can adopt the angle of friction of regulating alignment films in the production technology to change the twist angle of liquid crystal in liquid crystal panel in the prior art and improve the photoelectric characteristic curve, but this can make the power consumption that drives the liquid crystal molecule rotation increase, also make simultaneously colour temperature and TCO ' 03 (TCO, the The Swedish Confederation of ProfessionalEmployees of dark attitude; Hereinafter to be referred as: regulation has the trend of deterioration with the brightness homogeneity of visual angle change TCO), be illustrated in figure 4 as the photoelectric characteristic curve comparison diagram of liquid crystal panel in the prior art, along with diminishing of twist angle, the counter-rotating of photoelectric characteristic curve improves, but be illustrated in figure 5 as in the prior art analog computation numerical value synoptic diagram of the brightness homogeneity that liquid crystal panel when changing the alignment film rubbing angle changes with twist angle, abscissa axis is a distortion angle, axis of ordinates is the variation number percent with the brightness homogeneity of visual angle change for regulation among the TCO ' 03, as seen diminishing along with twist angle, with the brightness homogeneity of visual angle change the trend of deterioration is arranged, and influence bigger the variation number percent of brightness homogeneity.
