Description
[technical field]
The utility model relates to a kind of wide-angle liquid crystal display (wide-viewingangle LCD) structure, particularly relates to a kind of wide-angle liquid crystal display with full view effect.
[background technology]
LCD (LCD) has many advantages, and for example volume is little, in light weight, low power consumption or the like.Therefore, LCD has been applied to hand-held computer, portable phone or the like electronic product widely.That is to say that LCD has replaced traditional cathode ray tube (CRT) gradually and become the main flow of display.Yet the shortcoming of traditional LC D maximum is its narrow viewing angle.
Have many LCD wide viewing angle technology to be suggested in recent years, one of them is exactly the multi-region vertical nematic LCD (multi-domain vertical alignment LCD is called for short MVA LCD) that Fujitsu proposes.Figure 1A and 1B figure diagrammatic cross-section are used for illustrating the operator scheme of MVA LCD.Figure 1A shows the state of liquid crystal molecule in the LCD of the electric field that does not have extra electric field or existence during less than critical voltage value (thre shold voltage).Include the substrate 100 (being designated hereinafter simply as CF substrate 100) of colored filter and include the substrate 102 (being designated hereinafter simply as TFT substrate 102) of membrane transistor parallel to each other to towards.Projection (protrusion) 104 and 106 is formed at respectively in CF substrate 100 and the TFT substrate 102.The negative different square of dielectric (hereinafter to be referred as minus) liquid crystal molecule 108 vertically is arranged between CF substrate 100 and the TFT substrate 102, thereby constitutes a liquid crystal layer 110.Because local effect (localeffects) tilts towards specific direction near liquid crystal molecule 108 meetings of projection 104 and 106, thereby has caused tilt angle (pre-tilts).
Figure 1B shows the state of liquid crystal molecule among LCD when extra electric field when existence is greater than critical voltage value.Because above-mentioned highfield make the orientation (orientation) of negative type liquid crystal molecule 1 08 be changed, and the sensing of these liquid crystal molecules 108 (director) is perpendicular to the direction of electric field.So owing to be opposite at the vergence direction of the liquid crystal molecule 108 of projection 104/106 both sides, making has different liquid crystal arrangement in same pixel.In other words, be exactly that projection 104/106 in each pixel becomes two or two above zone (domain) to pixel segmentation, thereby increase the visual angle.
Fig. 2 is the partial plan of traditional MVA LCD 200, the projection 104 that its demonstration is formed in the CF substrate 100 is one the one W type pattern, the projection 106 that is formed in the TFT substrate 102 is one the 2nd W type pattern, arranging the one W type pattern and W type pattern spacing, also having a common line (common line) 220 to pass through the center section of each pixel cell 210.Though each pixel cell 210 among the known MVA LCD 200 is divided into four zones, because liquid crystal arrangement still only favours 4 specific directions, so the contrast expression on ± 45 ° and ± 135 ° of orientation is not good.
In No. the 6532054th, United States Patent (USP), Ohmuro has a kind of MVALCD of announcement, and it is not to extend along fixed-direction that the Figure 16 in this patent and Figure 17 have the instruction protrusion, thereby has omnibearing visual angle.Although this method can increase angular field of view, yet this patent is not instructed the MVA LCD structure of this case.
