Abstract
A supporting device for LCD basal plate comprises a supporting lath, multiple supporting bosses and multiple vertical hoses; the multiple supporting bosses are fixed on supporting lath distantly; multiple vertical hoses are fixed on supporting bosses one to one. The device can lighten efficiently supporting trace of photoresist coating points during drying by means of pressure.
Description
[technical field]
The invention relates to a kind of baseplate support device, particularly about a kind of LCD (Liquid Crystal Display, LCD) baseplate support device.
[background technology]
Need in LCD (Liquid Crystal Display) array circuit (Array) the section processing procedure with the manufacture of semiconductor method with transistor fabrication on glass substrate, wherein mainly contain processing procedures such as photoresistance coating, exposure, development, drying, cleaning, etching.Drying process is after the photoresistance pattern forms, and takes contained solvent (Solvent) composition in the substrate surface residue photoresistance away, and then the photoresistance drying is solidified, and is beneficial to follow-up manufacturing process for cleaning, and when reducing solvent evaporates to the pollution of processing procedure thereafter.Drying under reduced pressure equipment (Low Pressure Dryer, LPD) be a kind of drying equipment commonly used at present, when liquid crystal display substrate is put into drying under reduced pressure equipment and carried out drying under reduced pressure, need a liquid crystal display substrate bracing or strutting arrangement under it, so that pick and place and locate substrate.
Fig. 1 announces a kind of liquid crystal display substrate bracing or strutting arrangement that is disclosed for the 6th, 473, No. 995 in the United States Patent (USP) on November 5th, 2002.This liquid crystal display substrate bracing or strutting arrangement 10 is positioned at drying under reduced pressure chamber 11, places a liquid crystal display substrate 50 to be dried on it.This liquid crystal display substrate bracing or strutting arrangement 10 comprises a base 14, a back up pad 15 and a plurality of support pin 16, this base 14 is positioned at the cavity lower surface of this drying under reduced pressure chamber 11, this back up pad 15 is positioned at this base 14 tops, and these a plurality of support pins 16 are positioned at the top of this back up pad 15 to support this liquid crystal display substrate to be dried 50.
Because liquid crystal display substrate 50 is supported by a plurality of support pins 16, this liquid crystal display substrate 50 is stressed relative concentrated with a plurality of support pin 16 contact points, thereby after the end of drying under reduced pressure processing procedure, place in liquid crystal display substrate 50 back sides and support pin 16 actual contact, unusual support vestige (Pin Mura) can appear in its relative photoresistance application point, thus the figure quality after the influence exposure.
[summary of the invention]
Produce the problem that the photoresistance application point supports vestige for overcoming prior art liquid crystal display substrate bracing or strutting arrangement, the invention provides a kind of liquid crystal display substrate bracing or strutting arrangement that can effectively alleviate photoresistance application point support vestige phenomenon.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of liquid crystal display substrate bracing or strutting arrangement is provided, comprise that one is supported batten, a plurality of support rim and a plurality of vertical setting of types flexible pipe, these a plurality of support rim fixed interval support on the batten at this, and these a plurality of vertical setting of types flexible pipes are fixed on these a plurality of support rims one to one.
Compared to prior art, liquid crystal display substrate bracing or strutting arrangement of the present invention adopts a plurality of vertical setting of types flexible pipes to replace the support pin of prior art, because vertical setting of types flexible pipe and liquid crystal display substrate contact area are relatively large, and the vertical setting of types flexible pipe is low than support pin hardness again, supports mark problem so liquid crystal display substrate bracing or strutting arrangement of the present invention can effectively alleviate owing to supporting the liquid crystal display substrate photoresistance application point that causes.
[description of drawings]
Fig. 1 is the synoptic diagram of prior art liquid crystal display substrate bracing or strutting arrangement, and it is indoor that it is positioned at a drying under reduced pressure.
Fig. 2 is the schematic perspective view of liquid crystal display substrate bracing or strutting arrangement of the present invention.
Fig. 3 is the local enlarged diagram of III part among Fig. 2.
Schematic perspective view when Fig. 4 is liquid crystal display substrate bracing or strutting arrangement of the present invention work.
Fig. 5 is the rear view of Fig. 4.
[embodiment]
Please consulting Fig. 2 and Fig. 3 together, is the schematic perspective view and the local enlarged diagram of liquid crystal display substrate bracing or strutting arrangement of the present invention.This liquid crystal display substrate bracing or strutting arrangement 20 comprises that eight are supported 28,160 support rims 24 of batten and 160 vertical setting of types flexible pipes 22, wherein each supports on the batten 28 and fixes 20 support rims 24 at certain intervals, and fixes a vertical setting of types flexible pipe 22 on each support rim 24.
This support rim 24 is to be made by aluminum profile extrusion with this support batten 28, this vertical setting of types flexible pipe 22 is by polyimide material (Polyimide, PI) flexible pipe of making, its tube wall is thinner, certainly, the material of liquid crystal display substrate bracing or strutting arrangement 20 each several parts also can according to circumstances change, and can adopt metal material or other suitable nonmetallic materials such as copper as support rim 24 and this support batten 28, and vertical setting of types flexible pipe 22 can be used other plastic materials instead.
Connected modes such as that the fixed form of this support rim 24 on this support batten 28 can adopt is bonding, welding and bolt connection, this vertical setting of types flexible pipe 22 can sockets or are bonded on this support rim 24.
Please consult Fig. 4 and Fig. 5 together, solid and rear view when being liquid crystal display substrate bracing or strutting arrangement of the present invention 20 work respectively.When liquid crystal display substrate bracing or strutting arrangement 20 of the present invention is worked, put it into earlier in the drying under reduced pressure chamber 31, make eight to support batten 28 parallel being placed in the drying under reduced pressure chamber 31, again liquid crystal display substrate to be dried 60 is lain against this above vertical setting of types flexible pipe 22, at last, close drying under reduced pressure chamber 31 closing doors (figure does not show), start decompression aspiration pump 32 and can carry out drying under reduced pressure.
The quantity of the support rim 24 that liquid crystal display substrate bracing or strutting arrangement 20 of the present invention is comprised, support batten 28 and vertical setting of types flexible pipe 22 also can be adjusted in addition according to size of substrate and actual conditions, the vertical setting of types flexible pipe also is not limited to be fixed on one to one on the support rim, also can be fixed on the support rim by several vertical setting of types flexible pipes.
These vertical setting of types flexible pipe 22 tube walls are thinner, has certain flexibility, thereby can reduce the contact stress of liquid crystal display substrate to be dried 60 is concentrated, again because prior art only has the support pin about 4 four ten to support a liquid crystal display substrate, liquid crystal display substrate bracing or strutting arrangement 20 of the present invention adopts the vertical setting of types flexible pipe 22 more than prior art, thereby can alleviate the weight of sharing on each vertical setting of types flexible pipe 22, on liquid crystal display substrate to be dried 60 photoresistance application points, produce the phenomenon that supports vestige thereby effectively alleviate even eliminate owing to supporting.
