Description
Technical field
The present invention relates to lcd technology, the liquid crystal indicator that particularly a kind of low-temperature stability is good.
Background technology
By and large, based on the difference of liquid crystal deflecting element mode, liquid crystal display (hereinafter referred to as LCD) can be divided into two large classes: the first kind is that liquid crystal molecule deflects along the plane vertical with substrate, and Equations of The Second Kind is that liquid crystal molecule is along deflecting with the plane of substrate-parallel.
Typical first kind LCD is Twisted Nematic LCD (being called for short TN-LCD), has two electrodes and is arranged at the relative inner side of upper and lower two substrates respectively.The liquid crystal molecule of TN-LCD is generally configured to 90 degree of deflections, the feature such as have high transmission rate, low-power consume, technique is easy.But, because the liquid crystal near two-plate surface points to mutually vertical, make it show narrow visual angle.
Typical Second Type LCD is transverse electric field deflector type liquid crystal display (being called for short IPS-LCD) and fringing field deflector type liquid crystal display (being called for short FFS-LCD), their two electrodes are formed on same substrate, and liquid crystal is along deflecting with the plane of substrate-parallel.Due to turn off at voltage state time, liquid crystal points to system horizontally and be parallel to substrate, and thus its viewing angle characteristic is improved.And because the field parallel in region between two electrodes is in the substrate of display, the plane deflection namely making liquid crystal be directed to parallel substrate makes it obtain wide viewing angle.But the electric field in region near two electrode surfaces can be stronger, but from two electrodes more away from region electric field intensity more weak, so just cause the liquid crystal molecule near away from the substrate of electrode side almost just not deflect, and then the region of formation low penetration rate.
Be illustrated in figure 1 the liquid crystal indicator of a kind of tool wide viewing angle and high penetration, Fig. 2 is the cut-away view along AA line of Fig. 1, and present composition graphs 1 and the liquid crystal indicator of Fig. 2 to this tool wide viewing angle and high penetration are described.Comprise and be oppositely arranged first substrate 131 and the structure described in second substrate 132, Fig. 1 is a pixel cell 001 being arranged between first substrate 131 and second substrate 132.Wherein, first substrate 131 is the color membrane substrates of liquid crystal indicator, and second substrate 132 is the array base palte of liquid crystal indicator.
Described liquid crystal indicator comprises: the sweep trace 002 formed by different metal layer and data line 003 are arranged on the second substrate 132 of liquid crystal indicator along horizontal direction and vertical direction, thus limits pixel cell 001.N bar grid line and M bar data line intersected with each other, to realize N × M pixel cell on liquid crystal indicator.But in order to illustrative ease, illustrate only a pixel cell 001;
Form switching device at the point of crossing place of sweep trace 002 and data line 003, comprise the thin film transistor (TFT) (TFT) of grid 004, source electrode 0051, drain electrode 0052.Wherein, grid 004 is connected with sweep trace 002, and source electrode 0051 is connected with data line 003, and drain electrode 0052 is electrically connected with the first electrode 106.Signal on data line 003, by grid 004 actuating switch device, 0052 is sent to the first electrode 106 by source electrode 0051, drain electrode by the signal inputted by means of sweep trace 002;
The first interval body 103 and the second interval body 104 is also provided with on the upper strata of data line 003, first electrode 106, second electrode 107 is coated on the first interval body 103 inwall relative with the second interval body 104, to form the horizontal component of electric field parallel with first substrate 131, second substrate 132, with keep the major axis of the liquid crystal molecule in the liquid crystal layer 122 between the first interval body 103 and the second interval body 104 regardless of under which kind of state all the time all with first substrate 131, second substrate parallel 132;
Liquid crystal indicator is also formed with the memory capacitance of maintenance first electrode 106 voltage.Described memory capacitance comprises the first pole plate 108 and is positioned at the second pole plate 109 of its lower floor, is separated with the first insulation course 141 mutually between described first pole plate 108 and the second pole plate 109.Wherein, described first pole plate 108 is connected with the drain electrode 0052 of TFT, be separated with the second insulation course mutually between described first pole plate 108 and the first electrode 106, described first pole plate 108 and the first electrode 106 are electrically connected by the first via hole 111, by Signal transmissions to the first electrode 106 on data line 003; Be separated with the first insulation course 141 and the second insulation course 142 mutually between described second pole plate 109 and the second electrode 107, described second pole plate 109 is electrically connected with the second electrode 107 by the second via hole 112.
It should be noted that, in each pixel cell, the first interval body 103 extended along data line 003 direction and the second interval body 104 can't run through whole unit picture element, as shown in fig. 1, but leave space at the first interval body 103 and the second interval body 104 lower end (said D score end is direction in Fig. 1) herein, liquid crystal in layer of liquid crystal molecule 122 circulates between each unit picture element by this space, thus ensures the homogeneity of liquid crystal molecule.
Said structure by being arranged in the opposing sidewalls of a pair interval body in pixel cell by two electrodes, thus forms excellent horizontal component of electric field.Most of fringe region of described pixel cell inside still can keep good horizontal direction, thus makes liquid crystal indicator obtain higher transmitance and wide viewing angle.Moreover, on the sidewall being arranged on interval body due to two electrodes instead of substrate, avoid the obstruction that electrode pair navigates within the light of first substrate and second substrate, provide the transmittance of liquid crystal indicator.
If but by the interval body in pixel cell, the box that the partition wall formed as the first interval body 103 and the second interval body 104 controls liquid crystal indicator is thick, a series of problem can be brought: because interval body needs the liquid crystal cell between support first substrate 131 and second substrate 132 thick, and need on its sidewall, form the first electrode 106 and the second electrode 107, so the material of interval body must have sizable rigidity, otherwise the loosely organized of liquid crystal indicator or electrode will be made to occur defect, but rigid material is poor in particular for the low-temperature characteristics of the spacer material supporting space, performance at low temperatures, thermal shrinkage causes layer of liquid crystal molecule volume to reduce, but described rigid material can not reduce thereupon, so the vacuum area between interval body and layer of liquid crystal molecule can be caused, and in these regions, produce bubble, meanwhile, if when first substrate 131 or second substrate 132 have pressure, described rigid material because of pliability poor, cannot change with ambient pressure, will the damage of liquid crystal indicator be caused.
