Embodiment
Below, will describe illustrative embodiments of the present invention in detail referring to accompanying drawing.Yet the present invention can also other different forms realize, so the present invention's each embodiment that should not be interpreted as here being set forth.
In the accompanying drawings, for the sake of clarity, the thickness in layer, film, plate and zone etc. is all by exaggerative.In whole instructions, similarly reference number is represented similar element.Be appreciated that when the element such as layer, film, zone or substrate be known as " being positioned at " another element " on " time, this element can be located immediately on this another element or also can have the element of insertion.
Now, referring to the LCD of Fig. 1 to 3 detailed description according to illustrative embodiments of the present invention.
Fig. 1 is the synoptic diagram according to the LCD of illustrative embodiments of the present invention, Fig. 2 is the sectional view that comprises the LCD of film transistor array plate, common electrical pole plate and sept disposed thereon respectively, and Fig. 3 is the sectional view that LCD III-III along the line shown in Figure 1 is got.Arrow among Fig. 3 is represented the moving direction of the liquid crystal material of liquid crystal material after arranging.
Referring to Fig. 1, LCD 300 comprises a plurality of pixel P that are arranged on the containment member 310 on LCD 300 outermost portions and are arranged on inside.Hereinafter, the zone that is provided with a plurality of pixel P in the LCD 300 is known as the viewing area, and all the other zones are called the surrounding zone.
A plurality of less pearl sept group 320a are arranged on around the edge of viewing area, and a plurality of big pearl sept group 320b is arranged in the viewing area.Yet the layout of these pearl septs group 320a and 320b can change.
A plurality of less pearl sept group 320a and a plurality of big pearl sept group 320b alternately are arranged in the surrounding zone between viewing area and the containment member 310 at regular intervals.
Referring to Fig. 2, less pearl sept group 320a is arranged on the film transistor array plate 100, and big pearl sept group 320b is arranged on the common electrical pole plate 200.Yet these pearl septs group 320a and 320b also can be arranged on the plate in tft array plate 100 and the common electrical pole plate 200 together.
Each sept group 320a and 320b can be arranged on corresponding on the zone that hinders light member (not shown).In each sept group 320a and 320b, a plurality of septs can be arranged, for example the sept of six to eight same sizes.Certainly, the number of the sept in sept group 320a and the 320b can be less than six or more than eight, and the shape of sept group 320a and 320b can change, as quadrilateral etc.
A plurality of less sept group 320a and a plurality ofly can alternately be arranged at regular intervals in the surrounding zone between viewing area and the containment member 310 than large-spacing thing group 320b.
Shown in arrow among Fig. 3, when liquid crystal material is outside the viewing area moves to the viewing area, liquid crystal material is repeatedly by the big pearl sept group 320b of gap process in the big pearl sept group 320b, and less Over or around pearl sept group 320a, to arrive containment member 310.Thereby the speed of the liquid crystal material in the surrounding zone between viewing area and containment member 310 can be reduced, and can avoid liquid crystal material to touch containment member 310 basically before containment member 310 sclerosis.A plurality of pearl sept group 320a and 320b are at regular intervals and being set in sequence in the surrounding zone between viewing area and the containment member 310 of rule, on several directions, to keep the speed of liquid crystal material basic identical, simultaneously liquid crystal material is moved towards containment member 310.
In addition, can be held therefore along the speed of the liquid crystal material of several directions that liquid crystal material can arrive containment member 310 basically simultaneously in several directions, thereby avoid the uneven distribution of liquid crystal materials in the LCD 300, and keep constant cell gap.
As shown in Figure 1, comprise a plurality of pearl sept group 320a and 320b, arrange in the mode of a sept group of per three pixels according to the LCD of illustrative embodiments of the invention.Yet these pearl septs group 320a and 320b also can arrange with the pixel separation that changes.
In LCD, the pressure that is applied on the middle body of viewing area may be more much bigger than the pressure on the Outboard Sections that is applied to the viewing area, thereby the cell gap of middle body is shorter than the cell gap of Outboard Sections.Thereby cell gap can not obtain constant maintenance.Comprise the big pearl sept group 320b in the middle body that is arranged on the viewing area and be arranged on less pearl sept group 320a in the Outboard Sections according to the LCD 300 of illustrative embodiments of the present invention, thereby can in whole viewing area, keep constant cell gap.
In addition, can during arranging (disposition) liquid crystal material, the Outboard Sections of liquid crystal material towards the viewing area be scattered unevenly, thereby the cell gap of Outboard Sections can be longer than the cell gap of middle body.Thereby layout and the size of these pearl septs group 320a and 320b can change, and therefore big pearl sept group 320b is arranged in the Outboard Sections, and less pearl sept group 320a is arranged in the middle body.In addition, can also use and have same size but different flexible pearl sept group.
Now, referring to the LCD of Fig. 4 detailed description according to illustrative embodiments of the present invention.Fig. 4 is the synoptic diagram according to the LCD of illustrative embodiments of the present invention.
As shown in Figure 4, the planar structure of LCD 300 is with shown in Figure 1 identical.LCD 300 comprises the containment member 310 that is arranged on LCD 300 outermost portions, be arranged on a plurality of pixel P of LCD 300 inside, and with a plurality of pearl sept group 320a and 320b on the constant surrounding zone that is disposed between viewing area and the containment member 310.
Yet different with the LCD shown in Fig. 1, a plurality of less pearl sept group 320a and a plurality of big pearl sept group 320b alternately are arranged in the viewing area.
LCD 300 comprises a plurality of pearl sept group 320a and 320b, and these pearl sept groups are of different sizes and alternately are provided with, with constant cell gap and the liquid crystal material distribution uniformly that keeps localized variation in the viewing area.
Therefore, when after arranging liquid crystal material, two display boards being assembled together, big pearl sept group 320b can keep constant cell gap, simultaneously when local pressure is applied on the display board, less pearl sept group 320a can avoid the elastic force of big pearl sept group 320b to occur allowing that pearl sept group 320b compression surpasses the situation of certain point by supporting two display boards.
Below, will be referring to Fig. 5 to the LCD of Fig. 7 detailed description according to illustrative embodiments of the present invention.Fig. 5 is the arrangenent diagram according to the LCD of illustrative embodiments of the present invention.Fig. 6 is the sectional view that LCD VI-VI along the line shown in Figure 5 is got, and Fig. 7 is the sectional view that LCD VII-VII along the line shown in Figure 5 is got.
