Description
[technical field]
The present invention relates to a kind of liquid crystal indicator, particularly a kind of plane inner switching type liquid crystal displaying apparatus.
[background technology]
Liquid crystal indicator is a kind of in the flat display apparatus, and it is through in decades development, not only occupies critical role and increase with its growth in the application of notebook, is also occupying increasing share as fields such as displays.And its flourish basic reason is the raising of the display effect brought of technical progress and the decline of price.
Because liquid crystal molecule in the vertical direction deflection meeting causes display viewing angles narrower in the prior art, many companies all research and develop relevant wide viewing angle technology, and IPS (In Plane Switching, in-plane changes) be exactly wherein have much advantage a kind of, its principle is that pixel electrode and public electrode produce a plane electric fields, liquid crystal molecule is rotated in the plane parallel with substrate to change the transmitance of light, because avoided the deflection of liquid crystal molecule in the vertical direction, can reach bigger observation visual angle.Its typical structure is be parallel to each other the also pixel electrode and the public electrode of staggered pectination.
See also Fig. 1, the United States Patent (USP) of announcing on October 1st, 2002 has disclosed an a kind of pixel region P of improved IPS liquid crystal indicator for the 6th, 459, No. 465.This pixel region comprises the parallel concentric line 135 of the vertical grid line 113 of data line 115 and data line 115 and data line 115, is arranged on TFT (Thin Film Transistor, thin film transistor (TFT)) 120, public electrode 133 and the pixel electrode 131 of data line 115 and grid line 113 intersections.The grid 121 of TFT 120, source electrode 123 and draining 125 is connected with grid line 113, data line 115 and pixel electrode 131 respectively, and public electrode 133 is connected with concentric line 135.This pixel electrode 131 and public electrode 133 are for being parallel to each other and being staggered, and for common comb electrode, it improves at what pixel electrode 131 is broken line shapes with public electrode 133, produce a pair of territory electric field.
See also Fig. 2, be the enlarged drawing in Fig. 1 ∏ district.Because pixel electrode 131 and public electrode 133 are broken line shapes, it produces a pair of territory electric field, liquid crystal molecule 130 is along both direction deflection under this electric field action, make this pixel on display effect, be divided into two zones, under more inclined to one side observation visual angle, the aberration that two zones cause can compensate mutually, so electrode adopts the liquid crystal indicator of this kind structure that better wide viewing angle characteristic is arranged.
But in the bending place of broken line, because electric field is unusual, the normally deflection of the liquid crystal molecule at this place makes light normally not pass through, so its brightness reduces.
Seeing also Fig. 3, is under different LCD alignment directions and electrode angle, the graph of a relation of voltage and transmittance.In IPS type liquid crystal indicator, when the angle of LCD alignment direction and electrode is big, liquid crystal can be used lower driven, but its transmittance can reduce rapidly with the increase of driving voltage, therefore the degree of accuracy of driving voltage is had relatively high expectations, that is to say the processing procedure of TFT and signal wire and electrode is had relatively high expectations, and when this angle hour, transmittance can not reduce because of driving voltage increases obviously, but its required driving voltage is higher.
Two territories electrode structure of prior art equals the average result of the situation of two different angles on driving, therefore the requirement of processing procedure and driving voltage is not all needed very highly, but that it improves effect is comparatively limited.
Seeing also Fig. 4, is prior art contrast of LCD degree and visual angle graph of a relation.The contrast of broken line type electrode structure in-plane switching LCD device on the different directions visual angle of prior art differs bigger, the summation result in its pair territory is: reaching contrast height on the left and right directions up and down, in an inclined direction contrast is lower, it is less that the higher angular field of view of its contrast accounts for the ratio of whole circular angular field of view, so its viewing angle characteristic is not good.
[summary of the invention]

[embodiment]
See also Fig. 5 and Fig. 6, be the floor map and the sectional view of IPS liquid crystal indicator first embodiment one pixel region of the present invention, with definition shown in Figure 6 direction up and down, IPS liquid crystal indicator of the present invention comprises first substrate 201 and second substrate 202, liquid crystal layer 203, grid line 211 and data line 212, TFT 220, concentric line 213, bonding pad 231, connecting line 232, pixel electrode 233 and public electrode 243 and gate insulation layer 262 and passivation layer 261.Wherein, second substrate 202 is parallel with first substrate 201 and be positioned at its top; Liquid crystal layer 203 is between first substrate 201 and second substrate 202; Grid line 211 and data line 212 is vertical mutually, is all parallel equidistant and arranges, and it is arranged in first substrate 201, so it constitutes a plurality of patterns, and this pattern vertically extends to second substrate, 202 directions and constitutes a solid, is called a pixel region (sign); TFT 220 is arranged on grid line 211 and data line 212 infalls, and its cross-section structure comprises the grid 221 that is positioned at the below and is positioned at the source electrode 222 and the drain electrode 223 of the left and right sides, top; Concentric line 213 is in first substrate 201 and parallel with grid line 211; Connecting line 232 is parallel with grid line 211, and pixel electrode 233 and public electrode 243 are corresponding to this pixel region setting, and itself and bonding pad 231 all are arranged in first substrate 201; Gate insulation layer 262 is positioned on the grid 221, and passivation layer 261 is positioned on source electrode 222, drain electrode 223 and the gate insulation layer 262.Public electrode 243 has similar shape with pixel electrode 233, and it is parallel to each other and is staggered, its parallel direction vertical with grid line 211, this pixel electrode 233 and public electrode 243 are waveforms.
Grid line 211 is connected with TFT 220 grids 221 to transmit sweep signal, and this sweep signal is used for controlling the switch of TFT 220; Data line 212 is connected with data signal with TFT 220 source electrodes 222, and promptly source electrode 222 is used for receiving data-signal; TFT 220 drain electrodes 223 are connected with connecting line 232 by bonding pad 231, connecting line 232 is connected with pixel electrode 233, therefore pixel electrode 233 is connected with TFT 220 drain electrodes 223 formation electricity, when sweep signal makes TFT 220 when opening, drain electrode 223 is sent corresponding signal of video signal according to the data-signal of source electrode 222 receptions, be connected because pixel electrode 233 constitutes electricity with TFT 220 drain electrodes 223, this signal of video signal is sent to pixel electrode 233; Gate insulation layer 262 and passivation layer 261 are between pixel electrode 233 and public electrode 243, can isolate the two to avoid its contact, after pixel electrode 233 receives signal of video signal, potential difference (PD) between itself and the public electrode 243 makes and forms the approximate electric field that is parallel to first substrate 201 and second substrate 202 between two electrodes, this electric field make the liquid crystal deflecting element in the liquid crystal layer 203 and the transmitance that changes light with display image.Because pixel electrode 233 is waveforms with public electrode 243,, promptly show to be equivalent to continuous a plurality of territories, so this structure can be referred to as the continuous domain structure so the direction of an electric field that forms between the two changes continuously.
Seeing also Fig. 7, is that electrode is arranged and the liquid crystal deflecting element synoptic diagram in IPS liquid crystal indicator first embodiment one pixel region of the present invention.Corrugated pixel electrode 233 is parallel to each other and is staggered with public electrode 243, when having voltage to be applied on the two, liquid crystal molecule in the liquid crystal layer 203 (not indicating) is along direction of an electric field deflection, because two electrodes are waveform, the electric field of its formation changes continuously, so the yawing moment of the liquid crystal molecule in this pixel region also is continuous variation.And the transmittance of this pixel region is the summation of all liquid crystal deflecting element effects, also can be referred to as the summation of continuous electric field or continuous domain effect, because it is unusual to have eliminated the electric field of of the prior art pair of territory intersection liquid crystal deflecting element unusual and that cause, therefore the lower situation of transmittance of the prior art is avoided, thereby can reach higher brightness.
In the present embodiment, pixel electrode 233 satisfies following equation with the shape of public electrode 243:
x＝Asin(π*y/2L)
Wherein, x, y are respectively horizontal direction and vertical direction variable, and A is the level interval of adjacent pixel electrodes and public electrode, and L is the length of this pixel region, and 0≤Y≤L.
Seeing also Fig. 8, is the contrast and the visual angle graph of a relation of IPS liquid crystal indicator first embodiment of the present invention.Because pixel electrode 233 and public electrode 243 are waveforms, and it is parallel to each other, therefore the summation that can regard the parallel microelectrode of direction continually varying as, but not the combination of having only the parallel pole of both direction of the prior art, therefore when voltage is applied on pixel electrode 233 and the public electrode 243, the deflection of the liquid crystal molecule in the liquid crystal layer 203 also is continuous variation, liquid crystal molecule in one pixel region is corresponding to electrode shape, different yawing moments is arranged throughout, therefore its contrast is comparatively average on each visual angle, see also Fig. 4, compared to existing technology up and down and the left and right directions height, the performance that vergence direction is lower, the contrast of present embodiment is except being significantly improved up and down and on other direction the left and right directions, and it is up and down and still better on the left and right directions and since the observer may be not only at arbitrary visual angle of display device about and observe on the left and right directions, so this contrast viewing angle characteristic more meets the requirement of observation.
Simultaneously, because electrode is waveform, i.e. a curve shape, and the orientation of liquid crystal is a specific direction, so its angle with the LCD alignment direction changes continuously, its driving effect equals the summation under the different angle situations.See also Fig. 3, when the angle of LCD alignment direction and electrode is big, liquid crystal can be used lower driven, but its transmittance reduces rapidly with the increase of driving voltage, therefore processing procedure is had relatively high expectations, and when this angle hour, transmittance can obviously not reduce because of driving voltage increases, but its required driving voltage is higher.Therefore the summation driving effect under the different angle situations is: can drive under lower voltage, transmittance is slower again with the speed that the voltage increase descends simultaneously, and need not use accurate driving voltage, and is therefore lower to the requirement of processing procedure.
And with following equation:
X=Asin (π * y/NL), (N is the positive integer greater than 2)
The pixel electrode of the wave-like of expressing and public electrode obviously also have the advantage described in first embodiment.
See also Fig. 9, IPS liquid crystal indicator second embodiment of the present invention adopts the pixel electrode 273 and the public electrode 283 of arc, this structure also forms the continuous domain electric field, therefore also can b referred to as the continuous domain structure, its advantage can be described below: pixel electrode 273 and public electrode 283 are parallel to each other and are staggered, when having voltage to be applied on the two, liquid crystal molecule in the liquid crystal layer 203 (not indicating) is done continuous deflection along direction of an electric field, the electric field liquid crystal deflecting element unusual and that cause that of the prior art pair of territory intersection therefore can not occur is unusual, the defective that transmittance of the prior art is lower promptly is overcome, thereby can reach higher brightness; Because pixel electrode 273 and public electrode 283 are shaped as arc, and the orientation of liquid crystal is a specific direction, therefore the angle of itself and LCD alignment direction changes continuously, its driving effect is equivalent to the summation under the different angle situations, therefore this structure can drive under lower voltage, comparatively relax again owing to its transmittance increases the speed that descends with voltage simultaneously, so this structure is lower to the requirement of processing procedure; Because pixel electrode 273 and public electrode 283 are arc, and it is parallel to each other, therefore can regard as the summation of the parallel microelectrode of direction continually varying, when voltage is applied on these two electrodes, the deflection of the liquid crystal molecule in the liquid crystal layer 203 also changes continuously, and the liquid crystal molecule in the pixel region has different yawing moments throughout corresponding to the shape of electrode, therefore its contrast is comparatively average on each visual angle, and this kind contrast viewing angle characteristic more meets the requirement of observation.
In the present embodiment, pixel electrode 233 satisfies following equation with the shape of public electrode 243:
x＝Asin(π*y/L)
Wherein, x, y are respectively the variablees of horizontal direction and vertical direction, and A is the level interval of adjacent pixel electrodes and public electrode, and L is the length of this pixel region, and 0≤Y≤L.
Because the pixel region of IPS liquid crystal indicator of the present invention is that array is arranged, and first substrate, liquid crystal layer, second substrate can be collectively referred to as and make array substrate.
The shape of IPS common electrode of liquid crystal display device of the present invention and pixel electrode is not limited to waveform or arc, other electrode shape that can form the continuous domain electric field parallel with substrate also can adopt, and is also suitable as the curve shape of level and smooth straight line that links together and curve formation.
The concentric line of IPS liquid crystal indicator of the present invention, public electrode and pixel electrode can adopt transparent conductive material such as ITO (Indium Tin Oxide, tin indium oxide) etc.When adopting transparent material, can obtain high aperture opening ratio, thereby have higher brightness.
The public electrode of IPS liquid crystal indicator of the present invention can be vertical with grid line with the parallel direction of pixel electrode, and this moment, its concentric line can be parallel with grid line; Also can adopt the concentric line vertical, be connected with public electrode by increasing by a bus parallel with grid line with grid line.This concentric line can be one or more, and it can be directly to be connected or to constitute electricity by other connected mode to connect with public electrode.
