Description
Technical field
The invention belongs to display, particularly a kind of flat-panel screens with gap wall support structure.
Background technology
Along with the making thin-film electronic crystal technology is progressive fast, make the performance such as LCD (LCD), organic electro-luminescent display flat-panel screens such as (OLED) continue to promote, and a large amount of be applied to personal digital assistant's device (PDA), notebook computer, digital camera, take the photograph in the various electronic products such as video recorder, mobile phone.Add the positive input research and development of industry and adopt the production equipment that maximizes, the quality of flat-panel screens is constantly promoted, and the lasting decline of price, more make its application enlarge rapidly.
In the display panel manufacturing process of LCD, tend to by processing procedures such as film deposition and photoetching etchings, make a large amount of membrane transistors (TFT), pixel electrode (pixelelectrode) and crisscross each other sweep trace and data line pattern on the lower glass substrate surface, and construct required pel array (pixel array).On the other hand, then can make colored filter (colorfilter) and common electrode (common electrode) on the top glass substrate surface.Again top glass substrate is inverted the pixel array region top that is covered in the lower glass substrate surface, and between upper and lower glass substrate, injects liquid crystal layer, and constitute whole display panel.
In general, be made in the colored filter on top glass substrate surface, comprised the considerable unit of quantity picture element (pigment) and be surrounded on its black matrix" (black matrix on every side; BM).Wherein, ten hundreds of unit picture elements also are arranged in array-like, and according to its three kinds of primary colors such as catching green, redness or blueness respectively that put in order, and the pixel electrode (pixel electrode) below corresponding to respectively.As for, by black matrix" such as chromium metal film (Cr) or resin (resin) material structure, then be surrounded on respectively each unit picture element around so that cover the zone of the peripheral liquid crystal poor alignment of each pixel cell (pixel unit).
It should be noted that in the assembling process of display pannel, the stilt such as clearance wall (spacer) can be set, upper and lower two sheet glass substrates are separated, again in wherein pouring into liquid crystal for support effect enough between upper and lower glass substrate is provided.
The mode of widespread use is assembled with another sheet glass substrate for to utilize spreading machine that plastic cement ball (plastic beads) is spilt on a slice glass substrate that is distributed in wherein again in the known techniques.But adopt this kind mode, except the degree of uniformity of the size that can't accurately control all plastic cement balls and distribution, the plastic cement ball also may produce mobile, and shadow noon the product yield.
In order effectively to address the above problem, in present assembling processing procedure, then adopt lithographic process to make the clearance wall of column (photo spacer).Its main practice is first at top glass substrate surface coated one deck photoresist material layer, then utilizes very ripe photoetching (photolithography) processing procedure again, makes required clearance wall.Thus, accurately the size of control gap wall and position are fixed on clearance wall in light tight districts such as black matrix", and avoid descending because of the image quality that clearance wall causes exposure to cause.
As shown in Figure 1, on lower glass substrate 1 surface, make crisscross each other gate line (being sweep trace) 11 and data line 12 patterns with optical lithography, and on gate line 11 patterns on gate line 11 and next door, data line 12 lap positions, be constructed for controlling the membrane transistor 14 that corresponding pixel cell is operated.And, for fear of assembling upper and lower glass plate at 2,1 o'clock, the clearance wall that is made in top glass substrate can cover the zone of pixel electrode, in existing topological design, tend to make the clearance wall after the combination to be positioned at gate line 11 pattern range, and between left and right two data line 12 patterns.As shown in Figure 1, after top glass substrate 2 was assembled to lower glass substrate 1, clearance wall 21 was just in time on 11 patterns of the gate line between two data lines 12.
As shown in Figure 2, form the first metal layer earlier on lower glass substrate 1 surface, and see through the photoetching etch process, define gate line 11 patterns; Then, the dielectric layer and second metal level in regular turn above gate line 11, and carry out the photoetching etch process once again, and on second metal level, define data line pattern 12 and source/drain pattern, and define the dielectric pattern 13 that is used for isolating the first metal layer and second metal level.Wherein, source/drain pattern, dielectric pattern 13 constitute required membrane transistor 14 with gate line 11, as for data line 12, dielectric pattern 13 and gate line 11 overlappings, then can constitute projection cube structure 15.When top glass substrate 2 was assembled to lower glass substrate 1 top, clearance wall 21 just in time can contact at gate line 11, and between left and right two projection cube structures 15.
But it should be noted that, the above-mentioned clearance wall 21 that utilizes lithographic process to be made in top glass substrate 2 surfaces, owing to do not have a stickiness,, still can't fix upper and lower glass substrate 2,1 although therefore its top can press gate line 11 on the lower glass substrate 1.Thus, after the assembling of whole display panel is finished, do the time spent if top glass substrate 2 or lower glass substrate 1 are subjected to external force (shear stress), upper and lower glass substrate 2 with 1, just usually can be along the generation of the direction shown in arrow among Fig. 2 displacement.In case displacement is excessive, the aforementioned black matrix" that is made in top glass substrate 2, just can't cover in the bad zone of liquid crystal arrangement in the pixel cell fully, and then cause whole display pannel under dark attitude picture, produce the problem of light leak and cause the phenomenon of picture color inequality (Movable Mura).

Embodiment one
As shown in Figure 3, Figure 4, the flat-panel screens 3 of the present invention with gap wall support structure mainly comprises the lower glass substrate 30 that is used for making electric crystal, is used for making the top glass substrate 31 of colored filter 310 and is filled in the liquid crystal layer 32 of 30,31 of upper and lower glass substrates.
As for, at lower glass substrate 30 upper surfaces, then can make first conductive layer 401, dielectric layer 402 and second conductive layer 403 in regular turn.
In general, after depositing first conductive layer 401, then carry out the photoetching etching program, on first conductive layer 401, define several gate line patterns 401a.This skill person understands as being familiar with, and these gate line patterns 401a is horizontal is distributed in lower glass substrate 30 upper surfaces.After defining gate line pattern 401a, then can go up dielectric layer 402 with gate line pattern 401a in lower glass substrate 30, be used to provide insulation required between the conductive layer of first conductive layer 401 and subsequent deposition and isolate function.Subsequently, deposition second conductive layer 403 on dielectric layer 402 and lower glass substrate 30 surfaces, and see through photoetching etching program, the source of defining on second conductive layer 403/drain pattern 403a and several data line patterns 403b.Compared to several gate line patterns 401a of above-mentioned cross direction profiles, several data line patterns 403b for directly to be distributed in lower glass substrate 30 surfaces, and be staggered to form cancellate structure with several gate line patterns 401a.
It should be noted that owing on lower glass substrate 30, deposit first conductive layer 401, dielectric layer 402 and second conductive layer 403 in regular turn, therefore can form bulge-structure 40a, the 40b that piles up at its overlapping.As shown in Figure 3, bulge- structure 40a, 40b herein comprised that piling up the first bulge-structure 40a that forms by source/drain pattern 403a, dielectric layer 402 with gate line pattern 401a reaches by directly piling up the second bulge-structure 40b that constitutes to the data line pattern 403b that distributes, dielectric layer 402 with the gate line pattern 401a intersection of cross direction profiles.
As shown in Figure 3, Figure 4, the clathrate array that lower glass substrate 30 brake application polar curve pattern 401a and data line pattern 403b are arranged just in time is used for defining pixel unit array.Wherein, each grid is a zone that pixel cell is shared.In other words, the zone by adjacent gate line pattern 401a and adjacent data line pattern 403b institute corral is used for making a pixel cell.On the gate line pattern 401a and arranged on left and right sides surface of cross direction profiles, have two adjacent and straight data line pattern 403b on the lower glass substrate 30 to distribution.These two data line pattern 403b can be overlapping with gate line pattern 401a intersection separately, and pile up publish picture in two second adjacent bulge-structure 40b.
In addition, by source/drain pattern 403a, dielectric layer 402 and the first bulge-structure 40a that gate line pattern 401a is stacked into, in fact be the membrane transistor element.Because the drain of membrane transistor element is connected to data line pattern 403b and obtains document signal, therefore on layout is provided with, the first bulge-structure 40a can be adjacent to the data line pattern 403b of a correspondence, that is the first bulge-structure 40a can be adjacent to one second bulge-structure 40b.And, because each pixel cell, all need a membrane transistor circuit to drive, therefore as shown in Figure 3, between two second adjacent bulge-structure 40b, one first bulge-structure 40a can be set, i.e. membrane transistor element, and this first bulge-structure 40a is arranged at the left side of data line pattern 403b.
What particularly point out is, in order to keep between upper and lower glass substrate 31 and 30 space (gap) so as to filling liquid crystal layer 32, the supporting construction 50 that can make downward protrusion at the lower surface of top glass substrate 31; And, in order further to prevent to produce relative displacement because of being subjected to external force along plate face direction between upper and lower glass substrate 31 and 30, when being that top glass substrate 31 surfaces make supporting construction, need the special placement position of selecting supporting construction 50, make follow-uply when being assembled into top glass substrate 31 on the lower glass substrate 30, the sidewall of supporting construction 50 can just in time be conflicted on the sidewall of bulge-structure 40a, 40b.What specify is that supporting construction 50 herein can define clearance wall (photo spacer) at top glass substrate 31 lower surfaces by lithographic process and constitute.
As shown in Figure 3, Figure 4, in this embodiment, make the supporting construction of protruding 50 downwards at the lower surface of top glass substrate 31 common electrodes 311, and this supporting construction 50 is the block of strip.
When upper and lower glass substrate 31 and 30 is combined, the lower surface of supporting construction 50 just over against and press gate line pattern 401a in lower glass substrate 30.More the person between two second adjacent bulge-structure 40b, only is provided with a supporting construction 50, and the right sidewall of this supporting construction 50 just in time contacts at the first bulge-structure 40a, and left side sidewall then just in time contacts at the second bulge-structure 40b.Thus, owing to be subjected to the obstruction of first and second bulge- structure 40a, 40b,, can not produce relative displacement along plate face direction even upper and lower glass substrate 31 and 30 is subjected to the effect of shear stress yet.
Embodiment two
Except the supporting construction 50 of above-mentioned strip, also can select to contact at the first bulge-structure 40a and the second bulge-structure 40b respectively as Fig. 5, shown in Figure 6 with two supporting constructions.The supporting construction that promptly is made in top glass substrate 31 common electrodes 311 lower surfaces has comprised supporting construction 51a that is positioned at the left side and the supporting construction 51b that is positioned at the right side.Supporting construction 51a herein, 51b can be made into the rectangle block.Certainly, along with considering of processing procedure, supporting construction 51a, 51b also can be made into the block of cylindric or other shape.
Same, by adjusting supporting construction 51a and 51b in the position on top glass substrate 31 surfaces, when upper and lower glass substrate 31 and 30 is combined, the lower surface of supporting construction 51a, 51b can over against and press gate line pattern 401a in lower glass substrate 30.What specify is among this embodiment, between adjacent two the second bulge-structure 40b, can be provided with two supporting constructions that are respectively supporting construction 51a, 51b simultaneously.Wherein, the right sidewall of supporting construction 51a just in time contacts at the first bulge-structure 40a, and the left side sidewall of supporting construction 51b just in time contacts at the second bulge-structure 40b.Thus, owing to be subjected to the obstruction of first and second bulge- structure 40a, 40b simultaneously,, can not produce relative displacement along plate face direction even if upper and lower glass substrate 31 and 30 is subjected to the effect of shear stress yet.
Embodiment three
Except aforementioned use supporting construction contacts at first and second bulge-structure 40a, the 40b of and arranged on left and right sides simultaneously, also can be as Fig. 7, shown in Figure 8, also can make the supporting construction of downward protrusion directly push the upper surface of first and second bulge- structure 40a, 40b, step-like surface by first and second bulge- structure 40a, 40b bulge-structure, bigger friction force is provided, reaches the purpose that prevents upper and lower glass substrate 31 and 30 generation relative displacements.In the supporting construction 52 that top glass substrate 31 common electrodes 311 lower surfaces are made, also be the rectangle block, and the position of its layout face the second bulge-structure 40b.
When upper and lower glass substrate 31 and 30 is combined, the upper surface of the second bulge-structure 40b is directly pushed in the bottom surface of supporting construction 52, the left side sidewall of this supporting construction 52 just in time contacts at the first bulge-structure 40a that is adjacent to second bulge-structure 40b left side simultaneously.In such cases, owing to have bigger friction force between the supporting construction 52 and the second bulge-structure 40b, and the left side sidewall of supporting construction 52 is subjected to the first bulge-structure 40a simultaneously again and hinders, and therefore upper and lower glass substrate 31 and 30 also is unlikely to produce relative displacement along plate face direction.
Embodiment four
Certainly,, when stating supporting construction 52 in the use and contact at bulge-structure left, increase extra supporting construction again, be used for contacting at the bulge-structure on right side for better fixed effect is provided.Also can except at top glass substrate 31 common electrodes 311 lower surfaces, make a supporting construction 52 that faces the second bulge-structure 40b, also can additionally make a supporting construction 53 again on the right side of supporting construction 52 as Fig. 9, shown in Figure 10.Two supporting constructions 52,53 herein can be made into the rectangle block.
When upper and lower glass substrate 31 and 30 is combined, as aforementioned, the upper surface of the second bulge-structure 40b is directly pushed in the bottom surface of supporting construction 52, and the left side sidewall of this supporting construction 52 can contact at the first bulge-structure 40a that is adjacent to second bulge-structure 40b left side.Simultaneously, the right sidewall of supporting construction 53 then can just in time contact at another first bulge-structure 40a.Change speech, between two first adjacent bulge-structure 40a, two supporting constructions 52,53 can be set, contact at the first adjacent bulge-structure 40a separately laterally, to prevent upper and lower glass substrate 31 and 30 relative displacements that produce along plate face direction.
What particularly point out is, in order to prevent above-mentioned supporting construction the bright dipping of display pannel is impacted, and when supporting construction is set, preferably it is arranged in the light tight zone in the pixel cell.With the foregoing description, each pixel cell has all comprised the transmission region that is positioned at central authorities and has been surrounded on transmission region light tight zone on every side.Wherein, the transmission region that is positioned at central authorities is used for being provided with the usefulness of pixel electrode, then is to be used for being provided with above-mentioned gate line pattern 401a, data line pattern 403b or to be provided with such as lighttight materials such as black matrix"s as for light tight zone.When upper and lower glass substrate is combined,, just in time can be positioned at the scope in light tight zone in the supporting construction of top glass substrate lower surface.With the various embodiments described above, supporting construction is along the radial dimension of data line pattern 403b direction, need be less than the width of gate line pattern 401a, so that the projection of whole supporting construction on gate line pattern 401a can drop in the scope of gate line pattern 401a fully.
Owing to can make various elements such as membrane transistor, gate line pattern, data line pattern on the lower glass substrate 30, therefore often have stair-stepping bulge-structure on lower glass substrate 30 surfaces.Among the present invention,, when making upper and lower glass substrate 31 and 30 combining, support and the bulge-structure of the side of conflicting simultaneously by size and the position of adjusting top glass substrate 31 lower surface supporting constructions.Thus, originally support the function in space between upper and lower glass substrate except providing, and can prevent upper and lower glass substrate 31 and 30, thereby effectively avoid contingent light leak problem in the prior art along plate face direction generation relative displacement.
Though the present invention illustrates as above with preferred embodiments, so it is not in order to limit the present invention's spirit and invention entity, only to terminate in the foregoing description that.For example, though be to describe in the above-described embodiments, be an operator, when being applied to the flat display apparatus that may produce relative displacement between various upper and lower glass substrates easily with the technology characteristic of this case to being familiar with liquid crystal indicator.Be with, the modification of in not breaking away from spirit of the present invention and scope, being done, or, all should be included in the following claim of the design of this case technical characterictic expanded application to other flat display apparatus.
