Description
Technical field
The invention relates to a kind of display of tool staggered pixels, and particularly relevant for a kind of bore hole stereo-liquid crystal display device of tool staggered pixels.
Background technology
Due to liquid crystal display (Liquid Crystal Display, LCD) have that volume is thin, lightweight, power consumption is few and a characteristic such as radiationless pollution, its application is very extensive, its application product is from undersized portable type information products such as personal digital assistant (PDA), the notebook computer of stock size or the LCD Panel of desktop, as very diversified in the LCD TV of 30 inch～50 inch etc. to large-sized application product, make liquid crystal display become the indispensable important outfit of electronic product used in everyday.
For making liquid crystal display have wide viewing angle, make the observer all can watch the little image of colors of image and luminance difference from positive visual angle and side-looking angle, can form polygamy and improve the quality of side-looking image to zone (multi-domain) in single subpixel area.The wide viewing angle technology has numerous species, comparatively well-known as vertical orientation (Vertical Alignment, VA) type, copline switching (In Plane Switching, IPS)/boundary electric field switching (Fringe-field switching, FFS) type, with the three major types wide viewing angle technology such as twisted-nematic (Twisted Nematic, TN) type collocation wide viewing angle compensate film.Wherein, the panel of vertical orientation type wide viewing angle technology comprises again multiregional vertical align technology (the Multi-domain Vertical Alignment with protrusion (protrusion), MVA), with do not have protrusion but etch the patterning vertical orientation technology (Pattern Vertical Alignment, PVA) of a lot of finedraw in transparency electrode (as the ITO on colored filter).The existence of protrusion and finedraw all can make liquid crystal molecule produce tilt angle (Pre-tilt Angle) and produce tilting electric field.But the PVA technology can improve aperture opening ratio, makes brightness further to improve, the serious secretly problem of state light leak that does not also have traditional MVA technology to cause.in addition, also has polymkeric substance stabilization orientation (the Polymer StabilizationAlignment of development recently, PSA) technology, it is the polymer monomer (Monomer) that adds a little in liquid crystal molecule, after Liquid crystal pour is completed, carrying out alive operation makes the liquid crystal molecule near polyimide (Polyimide) zone produce tilt angle (pre-tilt angle), suitably shining UV light fixes its tilt angle again, and complete simultaneously polymer stabilizing (polymer stabilization) and LCD alignment, this technology can be improved the dark state light leak problem of previous MVA and then improve contrast.
In addition, also can carry out orientation with brushing or non-brushing formula for the inboard alignment film (Alignment Film) of upper and lower base plate (as thin film transistor base plate and colored filter substrate) processes, make liquid crystal molecule in the situation that have or not electric field all can arrange according to specific vergence direction and predetermined angle of inclination, complete the multizone orientation.For example ion beam orientation of non-brushing formula alignment technique (ion beam alignment), plasma beam orientation (plasma alignment) and light orientation (photo-alignment, PA) etc.Because non-brushing formula alignment technique can solve the pollution problem of brushing static that orientation produces or dust, and day by day come into one's own.Wherein, light orientation method is namely to utilize the ultraviolet light of polarization (UV) to cause the optics anisotropy with specific direction irradiation alignment film.Its method for making is mainly to coat the alignment film material macromolecular material of sensitization base (as contain) at glass substrate such as TFT substrate and CF substrate, again to its irradiation UV light, make macromolecular structure generation photopolymerization, isomerization or the cracking reaction of alignment film, the chemical bonding structure of luring the alignment film surface into produces special directivity, and automatic guide becomes the light-struck angle of UV, but with the pretilt angle auto arrangement of the liquid crystal molecule in further induced liquid crystal layer, becomes the high molecular direction of alignment film.
And liquid crystal display has been developed various technical products in response to 3D pattern demonstration trend.In ripe main flow 3DLCD product, majority is all that the mode that needs to be equipped with glasses is watched 3D at present, the shortcoming convenience, and therefore relevant dealer is developed towards bore hole 3D stereo display technique gradually.
Bore hole 3D display institute operation technique, be broadly divided into two classes, and the one, parallax barrier formula (Parallax Barrier) bore hole 3D display technique, another is lens pillar formula (Lenticular Lens) bore hole 3D display technique." parallax barrier " (Parallax Barrier) display technique is mainly to utilize light obscuration principle, to contain " parallax barrier " that staggered right and left eyes image forms by the trickle slit (Slits) of a whole row, the image that human eye is watched by slit will be left eye or the right-eye image after separating, and so can produce stereoscopic vision.Fig. 1 illustrates a kind of display schematic diagram of applying parallax barrier bore hole 3D display technique, and wherein parallax barrier 15 is seated in the place ahead of display panel 11, between human eye and display panel 11.Although backlight module 13 sends light source, but by black on parallax barrier 15 and transparent alternate grating, can limit the right and left eyes vision by visible pixel after grating, under contraposition designs accurately situation, the meeting that right and left eyes is seen respectively is odd pixel and even pixel, then as long as collocation shows different pictures at display panel 11 in odd pixel and even pixel, just can allow right and left eyes see different pictures, and then produce picture the vision of the depth of field is arranged, present stereo display.In addition, parallax barrier 15 also can be seated in the rear of display panel 11, and between backlight module 13 and display panel 11, black and transparent alternate grating can partly cover the light source that sends from backlight module, make light can only pass transparent place on grating, also can reach the effect that bore hole 3D shows.
In the tradition naked eye 3 D liquid crystal display, a plurality of rectangle sub-pixels are to arrange with the array way alignment, utilize transmissive slit (Slit) the alternate grating fringe vertical with light tight shield of barrier layer, be positioned over and merge on figure, and the perpendicular direction of the direction of slit and rectangle sub-pixel, but this kind set-up mode easily makes human eye experience repeatedly line effect (Moire effect).If but make slit with respect to sub-pixel inclination one angle setting, the crosstalk phenomenon (cross-talk) that easily has again image to interfere with each other.Fig. 2 illustrates in a kind of traditional naked eye 3 D liquid crystal display, the top view of the pixel of display module and parallax barrier.Display module 21 comprises a plurality of pixels, and each pixel is comprised of at least three not homochromy sub-pixels 22, as redness, green and blue subpixels.In Fig. 2, be position, 6 visual angles to be arranged as example take naked eye 3 D liquid crystal display, namely R1～R6 represents the 1st～the 6th corresponding red sub-pixel in visual angle.In Fig. 2, transmissive slit 251 on barrier layer 25 is and redness, green and blue subpixels inclination one angle setting, the zone of transmissive slit 251 has also comprised the partial image of the sub-pixel 22 of contiguous position, the same visual angle of non-genus, and causes crosstalk phenomenon (cross-talk).
