Embodiment
Array base palte provided by the invention, is formed with for reducing the staircase structure to the damage of friction cloth at this array base palte upper surface, thereby reduces the damage to friction cloth in friction process.
As the first embodiment, described staircase structure is formed by testing element group TEG, forming edge is stair-stepping TEG, this TEG comprises at least two independent retes and at least one covering rete, it is stepped that at least one group of adjacent independent rete one end indentation is from bottom to up formed with, and the stepped place of the outside corresponding independent rete of covering rete one end also forms stepped.
For example, shown in Figure 2, first layer metal thin layer 21 is to the second layer metal thin layer 22 formation staircase structure of successively decreasing step by step to one end of three-layer metal or transparent electrode thin film layer 23 again, TEG edge has also formed stepped, the TEG rete gradient is reduced, thereby can reduce the damage to friction cloth.
In addition, as the second embodiment, described staircase structure can not be to be formed by TEG, but new formation is positioned at the array of structures substrate on this liquid crystal display substrate, described staircase structure is to have the structural sheet of identical rete with TEG, this structural sheet comprises at least two independent retes and at least one covering rete, wherein, at least one group of adjacent independent rete one end indentation from bottom to up forms stepped, the stepped place of the outside corresponding independent rete of covering rete one end also forms stepped, between this structural sheet and TEG, there is setpoint distance, described setpoint distance is not for causing the safe distance of damage to friction cloth.
For example, shown in Figure 3, certain distance outside TEG34 edge, with a structural sheet 30 that there is identical rete with TEG, form staircase structures, the included independent rete of this structural sheet is first layer metal thin layer 31, second layer metal thin layer 32 and three-layer metal or transparent electrode thin film layer 33 one end step by step indentation form staircase structure, the edge that corresponding each metal level of covering rete of this structural sheet periphery forms one end of staircase structure has also formed stepped, structural sheet 30 has identical rete with TEG, and the distance between TEG 34 and structural sheet 30 neighboring edges can't cause damage to friction cloth, so both can reduce the damage to friction cloth, to TEG self, can not impact yet.In this example, the setpoint distance between this structural sheet 30 and TEG34 refers to the length between the platform right-hand member of structural sheet 30 upper ends and the left end of TEG34 upper end platform.
Each structural sheet can also have the rete not identical with TEG, no matter but whether rete is identical, the thickness of each structural sheet can according to from TEG between distance different and change, less with the thickness of TEG spacing structural sheet far away, so also can form staircase structure.
As the 3rd embodiment, described staircase structure can form at least one structural sheet on TEG and this array base palte, the thickness of each structural sheet is different and change according to the distance from TEG, less with the thickness of TEG spacing structural sheet far away, and between the neighboring edge of two adjacent structural sheets, have setpoint distance between the structural sheet adjacent with TEG and the neighboring edge of TEG, described setpoint distance is not for causing the safe distance of damage to friction cloth.
Illustrate, as shown in Figure 4, certain distance outside TEG 43 edges, with the structural sheet 40 that has different retes from TEG 43, form staircase structures, the rete of structural sheet 40 is rete 42, and the rete of TEG 43 is rete 41, the thickness of the Thickness Ratio TEG 43 of structural sheet 40 is little, and the distance between TEG 43 and structural sheet 40 neighboring edges can't cause damage to friction cloth, so both can reduce the damage to friction cloth, to TEG self, also can not impact.In this example, the setpoint distance between this structural sheet 40 and TEG43 refers to the length between the platform right-hand member of structural sheet 40 upper ends and the left end of TEG43 upper end platform.
As the 4th embodiment, described staircase structure can form at least two structural sheets on this array base palte, the thickness of each structural sheet is different and change according to the distance from TEG, less with the thickness of TEG spacing structural sheet far away, the structural sheet adjacent with TEG and TEG have identical rete, and between the neighboring edge of two adjacent structural sheets, have setpoint distance between the structural sheet adjacent with TEG and the neighboring edge of TEG, described setpoint distance is not for causing the safe distance of damage to friction cloth.
In above-mentioned the 4th embodiment, the described structural sheet adjacent with TEG itself also can form staircase structure, be that described staircase structure can also be for having the structural sheet of identical rete with TEG, this structural sheet comprises at least two independent retes and at least one covering rete, it is stepped that at least one group of adjacent independent rete one end indentation is from bottom to up formed with, and the stepped place of the outside corresponding independent rete of covering rete one end also forms stepped.
As shown in Figure 5, TEG 50 has first layer metal thin layer 51, second layer metal thin layer 52 and three-layer metal or transparent electrode thin film layer 53.TEG 50 and the first structural sheet 56 and the second structural sheet 55 form staircase structure, the rete of the first structural sheet 56 is rete 54, it has identical rete with TEG50, itself be also staircase structure, the thickness of the Thickness Ratio TEG 50 of the second structural sheet 55 is little, and the distance between TEG50 and the first structural sheet 56 neighboring edges, distance between the first structural sheet 56 and the second structural sheet 55 neighboring edges can't cause damage to friction cloth, so both can reduce the damage to friction cloth, and to TEG self, also can not impact.
In addition, in the embodiment of the present invention, to forming the ladder number of staircase structure, do not limit, as long as form staircase structure.
It should be noted that, in the forming process of pattern, the precision of pattern is main relevant with the precision of exposure machine, so the edge relation of the aligning accuracy of exposure machine and each rete is very large.If structural sheet and TEG are adjacent, two Edge Distances are less than or equal to aligning accuracy, and structural sheet and TEG just may connect together.Therefore, in the above-described embodiments, described setpoint distance need to be greater than the alignment precision of exposure machine.
Meanwhile, also require described setpoint distance (correspondence) to be less than friction cloth wool fibre diameter, the length (left and right is to size) of the platform of described structural sheet upper end is greater than friction cloth wool fibre diameter, to reduce the damage to friction cloth.
Therefore, no matter adopt several structural sheets and TEG to form staircase structure, between adjacent structural sheet, and the structural sheet adjacent with TEG and the setpoint distance between TEG need to be greater than the alignment precision of exposure machine, and be less than friction cloth wool fibre diameter.And when structural sheet is ladder, in structural sheet, the length of each platform is greater than friction cloth wool fibre diameter.
The present invention utilizes staircase structure can reduce the damage that in prior art, on substrate, TEG produces friction cloth, has not only reduced the bad incidence that rubs, and has extended the serviceable life of friction cloth, saves production cost.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
