Description
Technical field
The present invention relates to liquid-crystal display, particularly relate to optical compensation curved ocb mode liquid crystal indicating meter.
Background technology
Liquid-crystal display (LiquId Crystal Display, LCD) obtains develop rapidly because little, lightweight, the low in energy consumption and display quality of its volume is excellent, obtains especially and apply widely in portable electronic information product.Along with the increase of the LCD screen size for portable computer, office application, Video Applications, can be used in large screen display to make liquid-crystal display and finally instead of indicating meter (the Cathode Ray Tube of cathode tube, CRT), Railway Project is also had to need to solve.As improved viewing angle characteristic and improving response speed etc.The visual angle of LCD is narrow refer to leave observe perpendicular to liquid crystal cell normal direction time, contrast gradient obviously declines, and for gray scale and colored display, the phenomenon of gray scale and colour reversal also can occur when visual angle is large, had a strong impact on the display quality of LCD.Viewing angle problem becomes the large obstacle that LCD substitutes CRT technology.
The viewing angle problem of LCD is determined by the principle of work of liquid crystal itself.Liquid crystal molecule is bar-shaped, and different molecular arrangement modes correspond to different optical anisotropies.Incident light and liquid crystal molecule angle less, degree of birefringence is less; Otherwise degree of birefringence is larger.Departing from display screen normal direction, incide the light of liquid crystal cell with different angles different from the angle of liquid crystal molecule director, and under therefore causing different visual angles, effective path difference △ n*d is different.And the optimal light path difference of liquid crystal cell designs according to the normal direction perpendicular to box, for the light of oblique incidence, minimum transmittance increases with the increase of angle, and contrast gradient will decline.When angle is enough large, even there will be the phenomenon of contrast inversion.
The principle of work of liquid crystal also determine the response speed of LCD.In an lcd, liquid crystal molecule rotates along with the applying of electric field, and its response speed determined by the mechanical rotation of liquid crystal molecule, and its response speed of most of LCD is all at about 16ms on the market.Obviously, in order to reach better dynamically image quality effect, and the application such as 3D display, more and more higher to the requirement of LCD response speed.
At present, the method that proposed a variety of solution viewing angle problem is as optical compensation curved (OpticallyCompensated Bend, OCB) pattern, in-plane switching mode (In-Plane Switching, IPS), fringe field switching mode (Free Fall Sensor, and multidomain homeoptropic pattern (Multi-Domain Vertical Alignment, MVA) etc. FFS).They have respective relative merits, and multidomain homeoptropic pattern has the feature of high-contrast and response fast, but it needs a biaxial compensation film and two ellipsoidal polarizing plates, and therefore cost is higher.In-plane switching mode only needs linear polarizer and does not need compensate film, and just its response speed is too slow, can not show the picture of rapid movement.
As shown in Figure 1, wherein Fig. 1 (a) illustrates the bend alignment of liquid crystal molecule when not powering up in the essential structure of optical compensation curved (Optically Compensated Bend, OCB) pattern.On two pieces of substrates, liquid crystal molecule planar orientation, but arranged anti-parallel.During low voltage drive, in liquid crystal cell, liquid crystal director is bend alignment, and after high voltage, the arrangement of liquid crystal is close to (Fig. 1 (b)) arranged vertically.
Owing to having done certain surface treatment at upper and lower substrate, the orientation of liquid crystal molecule has had larger tilt angle (7 ° ~ 8 °), and the direction of both sides tilt angle is identical.When low electric field, the arrangement of liquid crystal molecule forms a kind of curved shape from top to bottom.During low electric field, the light delay of liquid crystal is 1/2 wavelength.For normal black pattern, when upper and lower polaroid is orthogonal time, light does not pass through.Not only the transmitance of vertical direction is 0, and the light of oblique incidence obtains goodish compensation due to the vergence direction complementation of top and the bottom liquid crystal molecule, and it is almost consistent that optical delay and vertical direction are observed, and the transmitance of oblique incidence light is also zero (Fig. 2).Such as, when the light of oblique incidence and the liquid crystal molecules parallel of front half storey or crossing angle very little time, assuming that value when its double refraction is less than vertical incidence, when continuing through the second half liquid crystal, light becomes larger angle with the liquid crystal molecule met, and at this moment its double refraction is by value when being greater than vertical incidence.Thus make the light of different vergence direction incidence suitable.If consider other one with the light of its corresponding tilt incidence, but identical position angle, angle of inclination and a upper light are antithesis.It is larger with the liquid crystal molecule angle of cut of lower floor, but becomes very little angle even parallel with the liquid crystal molecule on upper strata.After liquid crystal cell, the light delay of the light of such two relative tilts is equal, so both brightness is consistent, the symmetry at visual angle might as well.Be exactly that this display mode is named as optics self compensation and bends liquid-crystal display, i.e. OCB because this phenomenon.The reason that the visual angle of OCB liquid-crystal display that Here it is is wider, more symmetrical.
In addition, the direction that the director due to levels liquid crystal offsets under the effect of electric field is inconsistent, and one clockwise and another one is counter-clockwise, makes backfloweffect reduction caused in the process of direction of adjustment, thus reduce the time of response of this device.This backfloweffect, is that liquid crystal cell arranged in parallel or meander configuration liquid crystal cell are all relatively more remarkable, particularly in relaxation process, considerably increases time of lag.For OCB box, in relaxation process, upper and lower flow tendency is consistent, thus cancels out each other, and thus backfloweffect reduces greatly.Therefore OCB liquid crystal is shown with quickish response speed.
Based on above advantage, OCB indicating meter has wider visual angle and shorter time of response (Shaltzeit) relative to STN/TN class display.But OCB liquid-crystal display still has many shortcomings, as higher in the viscosity due to liquid-crystal composition, specific refractory power is not too suitable, and the time of response of indicating meter is comparatively slow, and visual angle is not wide; Therefore, need to provide that a kind of viscosity of liquid-crystal composition used is low, specific refractory power is suitable for, can reach that response is fast, the OCB liquid-crystal display of the good effect in visual angle.
Summary of the invention
The present invention based on task be to provide that not there is above-mentioned defect or that only there is above-mentioned defect not half ocb mode liquid crystal indicating meter, described ocb mode liquid crystal indicating meter selects the liquid-crystal composition that viscosity is low, specific refractory power is suitable, can reach the display effect that response is fast, visual angle is good.
