Description
Technical field
The present invention relates to information display screen technical field, particularly relate to a kind of full viewing angles-both vertical aligned liquid crystal display.
Background technology
The negative aobvious LCD(liquid crystal display of current TN) there is the problem of narrow viewing angle, STN(supertwist) negativity LCD product background color be blue, there is the problem that background color is not black, it is too narrow that common FSTN bears visual angle that is aobvious and FFSTN, visible angle is very limited, biaxial stretch-formed FFSTN(double compensation liquid crystal display) visual angle is wider, but polaroid cost is too high, and market rarely has appearance.
VA(is vertical orientated) mode LCD has high-contrast, the feature of wide viewing angle, main is all active matrix liquid crystal display, active matrix liquid crystal display Structure and energy is very complicated, manufacturing cost is high, substantially be applied in the large scale displays such as LCD TV, be difficult to be applied on undersized product.
At present existing VA(is vertical orientated) model application is on the passive matrix liquid crystal display of dynamic driving, the advantage that contrast is high is had in the dynamic driving of low way, visual angle is wider, but anti-visual angle exists visual angle blind zone, the 10 above product visual angle blind zone in road can, toward facing skew, make display effect be deteriorated, in addition, need the directional process of high-speed friction in production run, it is bad that this technique may introduce electrostatic, interior dirt etc., increases fraction defective.
Summary of the invention
Goal of the invention: the technical problem to be solved in the present invention is to provide a kind of full viewing angles-both vertical aligned liquid crystal display.
Technical scheme: a kind of full viewing angles-both vertical aligned liquid crystal display, comprise the upper polaroid connected in turn from top to bottom, upper transparency carrier, the first electrode, upper vertical orientated PI layer, negative liquid crystal layer, lower vertical orientated PI layer, the second electrode, lower transparency carrier and lower polaroid, described first electrode surface is provided with more than a pair measure-alike the first lateral trench and the first longitudinal groove, mutually vertical and be not connected mutually between the first adjacent lateral trench and the first longitudinal groove; Described second electrode surface is provided with more than a pair measure-alike the second lateral trench and the second longitudinal groove, mutually vertical and be not connected mutually between the second adjacent lateral trench and the second longitudinal groove; Second lateral trench to hang down between adjacent two first longitudinal grooves and with the equal vertical connection of adjacent two first longitudinal groove, form continuous print step-like; Second longitudinal groove between adjacent two first lateral trenchs and with the equal vertical connection of adjacent two first lateral trench, formed continuous print step-like.
Specifically, pixel is divided into the regular stepped region connected each other, and after powering up, between the grid of same pixel, voltage is identical, and display is consistent.
Upper and lower vertical orientated PI layer has vertical orientated effect to liquid crystal molecule, and liquid crystal is negative liquid crystal, and when not powering up, long axis of liquid crystal molecule is perpendicular to transparency carrier, and when powering up, liquid crystal molecule is perpendicular to certain direction of electric field line.
As preferably, described first lateral trench, the first longitudinal groove, the second lateral trench are all equal with the second longitudinal groove size, are longly 50-100 micron, are widely 5-30 micron.
Step-like in order to form continuous print, the distance between adjacent two first lateral trenchs, the first longitudinal groove, the second lateral trench or the second longitudinal groove is equal with the length of groove.
Above-mentioned first lateral trench, the first longitudinal groove, the second lateral trench or the second longitudinal groove identical length etc.
Upper polaroid and lower polaroid are the balanced polaroids of band, match in order to the optical path difference of compensation rate and negative liquid crystal layer can be made, the absorption axle angle in 90 ° of described upper polaroid and lower polaroid, the absorption axle of upper polaroid and the first lateral trench, the equal shape of the first longitudinal groove angle at 45 °, the absorption axle of lower polaroid and the second lateral trench, the equal shape of the second longitudinal groove angle at 45 °.
Principle of work: when not powering up, liquid crystal molecule homeotropic alignment, light can not be through, after powering up, bend maximum at the electric field line of slot wedge, under the effect of slot wedge electric field line, liquid crystal molecule near this type of electric field line is perpendicular to electric field line direction oblique arrangement, same groove two edges electric field line symmetric offset spread, the i.e. symmetrical oblique arrangement of the liquid crystal molecule on groove both sides, first electrode vertical groove right hand edge is consistent with the liquid crystal molecular orientation of adjacent the right second electrode vertical groove left hand edge, and the liquid crystal molecule symmetric offset spread on perpendicular direction between the first electrode vertical groove left hand edge and the second electrode vertical groove right hand edge, drive simultaneously and close on the inclination that liquid crystal molecule also has roughly the same angle, in like manner, transverse electrode also makes liquid crystal molecule symmetric offset spread in the transverse direction, light therethrough is had four view directions, just define the display effect at full visual angle.
Beneficial effect: advantage of the present invention is:
1, liquid crystal molecule is arranged by electrode trenches, without the need to traditional high-speed friction directional process, thus reduces the generation of interior dirt, electrostatic;
When 2, not powering up, liquid crystal molecule homeotropic alignment, background color is black, and after powering up, by the design of special electrode trenches, make liquid crystal molecule four direction symmetric offset spread, four view directions all have light therethrough, thus form full visual angle, without visual angle blind zone.
3, simply, cost is low for structure, technique.
