Technical field
The present invention relates to a kind of method of making and checking LCD panel.
Background technology
Along with the development of information society, the increasing demand that can produce the display of high quality graphic under, the lightweight prerequisite thin for, body little in energy consumption improves.In order to satisfy these requirements, studied various panel display apparatus at present, these devices comprise LCD (LCD), plasma scope (PDP), electroluminescent display (ELD), and vacuum fluorescent display (VFD).Part in these display techniques has been used for information and has shown.
In various panel display apparatus, LCD possibly be the most widely used a kind of display device.In fact, in such as mancarried devices such as notebook PCs, the LCD technology is own through having substituted the cathode ray tube (CRT) technology as the display mode of selecting for use.In addition, even in desktop PC and TV Monitor, also use the LCD device just more and more.
Basic LCD comprises opposed substrate and is located at the liquid crystal material between the substrate.
Liquid crystal is the material phase with the characteristic between liquid and solid.Liquid crystal has the flowability of liquid, but has the long-range crystal order of solid.Because liquid crystal has long-range crystal order and flowability, so liquid crystal has optical anisotropy.
The making of LCD need be accomplished with multiple working procedure, and these operations comprise the formation array, forms color filter (CF), fills (distribution) liquid crystal and makes assembly (describing in order).
The operation that forms matrix is included on first substrate (TFT substrate) and deposits, photomechanical production and etching to be to form thin film transistor (TFT) (TFT) array.The operation that forms color filter (CF) is included in and forms red, green and blue color filter on the black matrix, and ITO (tin is pluged with molten metal in the oxidation) film that on the CF substrate, has formed the common electrode effect.
Liquid crystal is filled (distribution) operation and is comprised and installing to TFT substrate and CF substrate in batch together.Usually, TFT substrate and colour filtering chip basic board are assembled into the little gap of formation between substrate.Then, inject liquid crystal to form liquid crystal board through clearance opening.
In the operation of making assembly, be connected to the driving circuit of handling input and output signal on the liquid crystal board.In addition, add upper side frame and process Liquid crystal module.
LCD normally assembles on production line.In the prior art, be input to the box that a plurality of TFT substrates or a plurality of colour filtering chip basic boards are housed respectively on the charging appliance.Each TFT substrate comprises the select lines of the direction extension in many edges and the data line of many square crossings.Thin film transistor (TFT) and pixel capacitors are arranged on the black matrix in zone between select lines and the data line.Each CF substrate all has black matrix layer, color filter and common electrode.Therefore, black matrix layer will be blocked except desirable and leaked from the light the light of pixel region.
From box, take out each TFT substrate or colour filtering chip basic board respectively and be sent to the input end of oriented layer production line through charging appliance.The production line that includes the manual programming robot forms oriented layer (with reference to the orientation procedure step 1S among Fig. 1) on each substrate.
Step 1S comprises that each substrate of cleaning is so that can form even orientation coating.Then, oriented material is coated on the substrate.Then, through removing the solvent in the oriented material and/or making oriented material produce heat polymerization oriented material is cured.After the curing, oriented material is carried out mechanical friction, thus form one fixedly liquid crystal make it to be orientated consistent surface.At last, carry out matting once more, and form oriented layer.
After forming the step 1S completion of oriented layer, need carry out several procedures and form the gap.These operations can or be carried out by continuous ground concurrently.The gap forms operation and comprises the matting (step 2S) of cleaning base plate (TFT substrate or colour filtering chip basic board) and be distributed to the wadding dispersion step (step 3S) on the substrate to wadding.Wadding is used to keep the gap thickness weighing apparatus fixed with consistent.
Can form the operation in gap, but on substrate, carry out sealant working procedure of coating (step 4S) (a kind of substrate [TFT or CF] is through forming the operation in gap, and another kind of substrate carries out sealant and applies).After cleaning step 2S, encapsulant is placed on the peripheral part of substrate.Finally, with encapsulant the TFT base plate bonding to the CF substrate, to form assembled plate.It should be noted that sealant working procedure of coating (4S) carries out on a kind of substrate (TFT or CF), and wadding disperses on another kind of substrate, to carry out.Therefore, as shown in Figure 1, production line has two branches.A branch cleans (step 2S) and disperses wadding (step 3S).(step 2S) and sealing (step 4S) are cleaned by another branch.
After wadding dispersion step 3S and sealant working procedure of coating 4S, carry out assembling procedure (5S), it comprises aligning, heats and is pressed onto the TFT substrate with colour filtering chip basic board so that produce the LCD plate.In assembling procedure, be arranged to TFT substrate and colour filtering chip basic board relative form and make its formation LCD plate that mutually combines.
Assembling procedure (step 5S) carries out cutting action (step 6S) afterwards, in this operation, cuts into a plurality of cell boards through the hollow LCD plate that will assemble with sliver that the cored slab that assembles is rule.
Accomplish cutting action (step 6S) afterwards; Liquid crystal filling orifice through on the encapsulant is annotated liquid crystal
in cell board, will inject then and prick sealing (step 7S).
At last, after step 7S,, each liquid crystal cells is polished (burr of removing cutting), and check with reference to step 8S.Just processed liquid crystal cell thus.
Schematically show the liquid crystal filling operation of the typical prior art of carrying out after each process step 6S among Fig. 2.Shown in figure, liquid crystal 25 is put into a container 30.Container 30 is inserted in the vacuum chamber 20.Vacuum chamber 20 is found time a period of time to remove the water that sticks on container 30 inwalls, water and the microbubble in the liquid crystal 25 in the liquid crystal 25.
Further, be immersed in the seal of a few module unit plates 40 in the liquid crystal subsequently with reference to Fig. 2.In chamber 20, introduce nitrogen (N2) gas and make it to produce atmospheric pressure.Pressure differential between the vacuum of cell board 40 and chamber 20 forces liquid crystal to get into cell board.
After each cell board 40 all injects liquid crystal 25, liquid crystal injecting port is sealed.Then the unit liquid crystal board is cleaned.Accomplished step 6S thus.
Although said method has its certain benefit, inject liquid crystal with said method and but have some problems.For example, the liquid crystal injection process needs for a long time, for example, pour into time that 10 inches plate needs above 10 hours.Infusion time is so long, and reason is that the very little area of perfusion that needs in the gap between the substrate is then relatively large.When making large tracts of land LCD, it is particularly serious that this problem just seems.In addition, owing to liquid crystal can be polluted and/or the performance that causes because of impurity and chemical reaction under the degradation reason, make remaining liquid crystal material not reuse, thereby said method can cause the waste of liquid crystal.In order to overcome these problems, suggestion adopts drip to apply the method for liquid crystal.
To introduce the liquid crystal drip-injection method simply with reference to Fig. 3 below.It should be noted that TFT and colour filtering chip basic board preferably adopt big glass substrate, this substrate comprises the plate district (tft array and color filter array) of a plurality of final each LCD displays of formation.In the liquid crystal drip-injection method, with liquid crystal drip-injection to each plate district of substrate.When first and second substrate in batch are installed to a time-out, the liquid crystal of instillation will be dispersed in the substrate plate district of whole base plate thereupon.
Referring now to Fig. 3, carry out orientation procedure 100S according to the method described above, make liquid crystal have consistent directivity.Then, with reference to step 102S, clean TFT and CF substrate.
Then, in step 103S, be put into CF substrate on the coating apparatus for sealant, and center on the perimeter distribution sealant in each substrate plate district through cleaning.Sealant is light/thermosetting resin preferably.It should be noted, wherein no longer need liquid crystal injecting port/perforate.
Simultaneously, in step 105S, being put on Ag (silver) distributing equipment so that on the common electrode supply lines of TFT substrate, form silver point through the TFT substrate that cleans.Then, in step 106S, the TFT substrate is put on the LC divider.Then, liquid crystal drip-injection to the plate district of substrate.
Subsequently, in vacuum assembling and curing schedule 107S, put into vacuum chamber to TFT and CF substrate.Afterwards, install to TFT and CF substrate in batch together, thereby the liquid crystal of instillation is full of in the gap between the substrate plate district equably.Make sealant cures to form the LC plate of combination then.The LC plate of combination is the big template with liquid crystal board district, a plurality of unit.
In S/B (line/sliver) step 108S, the LC plate that makes up is divided into single LC plate.S/B step 108S comprises in order to diamond and on glass surface, forms the crossed process of line of cut for the pen on basis, with through applying the sliver operation that power is separated each LC plate.
The surface of in polishing step 109S, grinding each LC plate is to remove deburring/flaw.Then, carry out the step 110S that each LC plate is carried out outward appearance and A/P (detecting automatically) detection, thereby accomplished the production process of LC display.
It is the electrical detection of using device that each LC plate is carried out that A/P detects, said device to unit LC plate in the input end that links to each other with data line of the select lines of TFT substrate apply predetermined voltage.It is very useful that A/P detects for defectives such as the defective in inspection box gap or LC leakages.
After the step 110S, form an assembly on each LC plate thereby be integrated into driver worker C, back light and combination frame.
Unfortunately, the liquid crystal drip-injection method also has the problem of himself.For example, after the LC plate with combination cuts into single LC plate, check outward appearance and electrical combination property by the workman.Owing to must test each LC plate, accomplish relatively difficulty and very time-consuming of test with the drive wire of predetermined all single LC plates of mode activated.Increase detection time thus and made the workman very tired.
Therefore, it is very useful adopting the electrical combination property of self-verifying combination LC display and the method for range estimation performance.More useful is to make the electrical combination property of the self-verifying combination LC display that is adopted and the method for range estimation performance can not bring excessive pressure or produce obviously influence to producing to the workman.
