Alignment device for LCD MODULE and cover glass

Technical field

The utility model relates to the alignment devices for being directed at LCD MODULE with cover glass.More specifically, this reality With the novel alignment device being related to for being directed at LCD MODULE with cover glass, which can be used for manufacturing and can press down Light leakage processed and the LCD device for improving durability.

Background technique

Liquid crystal display (LCD) device shows image in the following manner: light source is arranged below liquid crystal layer, and across liquid crystal Layer applies electric field, so that the orientation of liquid crystal molecule is aligned, so that being transmitted or being blocked from the light that light source emits.Liquid crystal display (LCD) device has than the thinner thickness of cathode-ray tube (CRT) display device and clearer picture quality, therefore it is answered For television set, monitor etc..Recently, LCD device is widely used as the portable terminal of smart phone, tablet computer etc. Display device.

Since image is presented by controlling the orientation of liquid crystal in LCD device, it is therefore necessary to be directed at the initial orientation of liquid crystal. If the initial orientation misalignment of liquid crystal, the orientation of liquid crystal can not be controlled, according to expectation so as to cause having hot spot on screen Or there is light leakage between the liquid crystal of misalignment.Therefore, it is carrying out for analyzing the light leakage origin cause of formation in LCD device and reducing The research of the origin cause of formation.In addition, since LCD device is applied to the portable terminal of smart phone, tablet computer etc. recently, Therefore the durability of LCD device becomes critically important.Therefore, the research of the durability for improving LCD device is being carried out.

Cause many because being known as of light leakage and decline.Wherein, when the bending of the lower substrate of LCD device, Ke Nengfa Raw light leakage.In addition, such lower substrate of LCD device can be easy to be damaged because of impact.This will be carried out A and Figure 1B referring to Fig.1 More detailed description.

Figure 1A is for illustrating the perspective view of the light leakage and decline that occur in LCD device.Figure 1B is along being used for Illustrate the sectional view of the line I-I ' interception of Figure 1A of the light leakage and decline that occur in LCD device.

A and Figure 1B referring to Fig.1, LCD device 100 include LCD MODULE 110 and covering LCD MODULE 110 Cover glass 130.LCD MODULE 110 is attached into cover glass 130 using clear binder 121.As shown in fig. 1b, liquid crystal Display module 110 includes lower substrate 111 and upper substrate 112.Lower substrate 111 and upper substrate 112 are attached at one with sealant 113 It rises, and liquid crystal LC is arranged between lower substrate 111 and upper substrate 112.LCD MODULE 110 is received from display printing electricity The signal of road plate 140, and image is presented based on the signal received.It is aobvious in LCD MODULE 110 and pad area PA Show that printed circuit board 140 contacts, and the lower base of the display printed circuit board 140 and LCD MODULE 110 in pad area PA Plate 111 contacts.In addition, when LCD MODULE 110 includes touch screen panel (TSP), for receiving the touch of touch signal Printed circuit board 150 contacts in pad area PA with the lower substrate of LCD MODULE 110.

Display printed circuit board 140 and touch printed circuit board 150 must be with lower bases that LCD MODULE 110 is arranged in Wiring circuit contact on plate 111.Therefore, upper substrate 112 cannot be arranged in above lower substrate 111 in pad area PA, and only Lower substrate 111 in pad area PA is exposed.Therefore, the durability of LCD MODULE 110 is in pad area PA than in non-weldering It is weak in the NPA of panel.

Lower substrate 111 in order to enhance weak durability of the LCD MODULE 110 in pad area PA, in pad area PA Filler 160 is set between cover glass 130.However, since filler 160 is for cover glass 130 to be fixedly attached to The stiffener of lower substrate 111, therefore filler 160 is not easy to deform.Specifically, due to the rigidity of filler 160, cause through Often arise a problem that: during the process that cover glass 130 is attached to LCD MODULE 110, lower substrate 111 occurs Bending, so as to cause the light leakage in LCD device 100.In addition, since the rigidity of filler 160 is not enough to buffer to lower substrate 111 Impact, therefore lower substrate 111 can be easy to be damaged because of impact.

Specifically, as shown in Figure 1B, use clear binder 121 by LCD MODULE 110 and Gai Bo in following process Glass 130 is attached together: firstly, being formed on upper substrate 112 every barrier (dam) 122, then being applied and is applied on upper substrate 112 The composition of clear binder.In addition, applying the composition for being applied to filler 160 on the lower substrate 111 in pad area PA.Every Hinder the 122 composite inhibiting overflows when the composition for clear binder is applied on upper substrate 112, and is applying It is cured before composition.Then, cover glass 130 is placed on 110 top of LCD MODULE and and LCD MODULE 110 alignments, and cover glass 130 is pressed, so that the lower surface of cover glass 130 is contacted with the composition for filler.Due to It is expected that the contact surface being used between the composition of filler and cover glass 130 is as big as possible, therefore cover glass 130 is excessive Pressing, and be also partially compressed under the effect of the pressure every barrier 122.

Then, it is used in the composition solidification of filler, while pressing cover glass 130 to form filler 160.It fills out It fills object 160 to be attached together cover glass 130 and LCD MODULE 110, until the composition for clear binder is consolidated Change, and cover glass 130 is kept to be aligned with LCD MODULE 110.On the other hand, clear binder 121 covers non-pad area The viewing area of display image in NPA.It must assure that there is no bubble between clear binder 121 and cover glass 130.It is transparent viscous Bubble between mixture 121 and cover glass 130 can make visual variation.Therefore, it is necessary to execute removal before composition solidification Process for the bubble between the composition and cover glass 130 of clear binder.Filler 160 is in the process phase for removing bubble removing Between keep cover glass be aligned with LCD MODULE 110.Composition for clear binder has weaker before it is cured Bonding force.In the case where no filler 160, cover glass 130 can not be with liquid crystal display during the process for removing bubble removing Module 110 is aligned.Therefore, it is necessary to a kind of for keeping cover glass 130 and LCD MODULE during the process for removing bubble removing The element of 110 alignments, that is, filler 160.That is, the composition for filler is in the combination for clear binder Solidify before object solidification, and cover glass 130 is attached to the lower substrate 111 of LCD MODULE 110 by filler 160, so that Cover glass 130 can be aligned by filler 160 with LCD MODULE 110.

In order to keep cover glass 130 to be aligned with LCD MODULE 110, need filler 160 have big elasticity modulus and Small elongation.That is, needing filler 160 that there is small elongation, to keep cover glass 130 and LCD MODULE 110 are aligned and keep the distance between cover glass 130 and LCD MODULE 110.In addition, it is necessary to which filler 160 has greatly Elasticity modulus so that cover glass 130 and LCD MODULE 110 are when offsetting with one another back to initial alignment.Namely It says, filler 160 is needed to need that there is enough rigidity.

When being applied to cover glass for the bubble between composition for clear binder that removes cover glass 130 When 130 pressure is revoked, due to the compressed elastic force every barrier 122, cause cover glass 130 that can increase.However, due to attachment There is rigidity to the filler 160 of cover glass 130 and lower substrate 111, therefore filler 160 has fixed thickness.Therefore, when When cover glass 130 increases, filler 160 is also increased, and the lower substrate 111 that filler 160 is attached is also with 130 1 raising of cover glass Height, as shown in fig. 1b.As a result, the lower substrate 111 in pad area PA bends.

When the lower substrate 111 in pad area PA bends, taking for some liquid crystal LC in non-pad area NPA can be made To change.That is, the part in non-pad area NPA of lower substrate 111 can also bend, so that non-pad area NPA In lower substrate 111 and the distance between upper substrate 112 can become inconsistent.Because between upper substrate 112 and lower substrate 111 Distance becomes inconsistent in non-pad area NPA, so the orientation of some liquid crystal LC ' can change.Specifically, closer to pad area The orientation of the liquid crystal LC' of PA is more possible to change.When between inclined liquid crystal LC' occur light leakage when, LCD device 100 it is bright Degree becomes inconsistent.

Meanwhile filler 160 is the stiffener with big elasticity modulus and small elongation, therefore it may be unsuitable for inhaling External impact is received, and possibly can not buffer the impact for applying the lower substrate 111 in pad area PA.In addition, when lower substrate 111 is sent out When raw bending, stress is applied to the inside of lower substrate 111, so that the durability of the lower substrate 111 in pad area PA can reduce. That is, even if being small impact, also it is easy to make the lower substrate 111 of pad area PA damaged, to reduce LCD MODULE 110 durability.

Therefore, the durability of LCD device can reduce.Specifically, in the week of the viewing area adjacent with pad area of LCD device Light leakage frequent occurrence at edge, and in the pad area of LCD device, lower substrate is often damaged.

Fig. 2A is the plan view for illustrating the LCD device of an illustrative embodiments according to the present utility model.Figure 2B is the sectional view along the LCD device of the line II-II ' of Fig. 2A illustrative embodiments according to the present utility model intercepted. Referring to Fig. 2A and Fig. 2 B, LCD device 200 include LCD MODULE 210, filler 260, clear binder 221, every barrier 222 With cover glass 230.In order to illustrate conveniently, the upper substrate 212 and cover glass 230 of LCD MODULE 210 are not shown in fig. 2. The display element being arranged in non-pad area NPA is omitted.

LCD MODULE 210 includes lower substrate 211, upper substrate 212, sealant 213, liquid crystal LC, driving chip DI, touching Template TP, display printed circuit board 240 and touch printed circuit board 250.

Lower substrate 211 supports the various assemblies of LCD device 200, and can be glass substrate or plastic base.Lower substrate 211 area is greater than the area of upper substrate 212.The side surface of lower substrate 211 is from the corresponding with the side surface of upper substrate 212 Side surface is prominent.Therefore, the part of the upper surface of lower substrate 211 is exposed.The region that the part of lower substrate 211 is exposed is determined Justice is pad area PA, and the region that lower substrate 211 and upper substrate 212 overlap each other is defined as non-pad area NPA.

In pad area PA, it is provided with driving chip DI, touch tablet TP and attaching components 260.In non-pad area NPA, It is provided with the display element of the pixel of LCD device 200 and the route for various signals to be transmitted to display element.Non- pad area NPA is divided into wherein to be disposed with display element and show the viewing area of image and be wherein disposed with and connect with display element Route and do not show the non-display area of image.Display device may include that thin film transistor (TFT) (TFT) and thin film transistor (TFT) connect The pixel electrode connect and the public electrode separated with pixel electrode.These routes transmit the voltage for driving display element, And it can be by for example for transmitting the gating line of gate voltage, the data line for transmitting data voltage and for transmitting touch The touch line of signal is constituted.

Driving chip DI is connect with display printed circuit board 240, and receives signal from display printed circuit board 240, with Driving voltage is provided to display element.For the ease of illustrating, it is not specifically illustrated driving chip DI in Fig. 2A, alternatively, with void Line indicates the driving chip region for being provided with driving chip DI.Driving chip DI may include for providing to display element The data driver of data voltage and/or for display element provide gate voltage gate driver.COG can be used Driving chip DI is mounted on lower substrate 211 by (chip on glass) technology.

Touch tablet TP connect with printed circuit board 250 is touched, and receives touch signal from line is touched, by touch signal It is transmitted to and touches printed circuit board 250.The either side of pad area PA is arranged in touch tablet TP, so that it is not handed over driving chip DI It is folded.It touches printed circuit board 250 and is connect via touch tablet TP with line is touched.In fig. 2, not specifically illustrated touch tablet TP, but The touch pad area of touch tablet TP is provided with dotted line instruction.

The either side of pad area PA is arranged in filler 260, so that it and the part touch tablet TP are overlapping.However, this is practical Novel range is without being limited thereto.For example, the either side in pad area PA can be set in filler 260 so that it not with touch tablet TP is overlapping.Although filler 260 has rectangular shape in fig. 2, the shape of filler 260 is without being limited thereto.For example, filling out Polygonal shape, circular shape or elliptical shape besides rectangular shapes can be formed as by filling object 260.Filler 260 Be used to that lower substrate 211 is attached to cover glass 230 in pad area PA so that even if cover glass 230 and lower substrate 211 it Between distance change, be also able to suppress the deformation of lower substrate 211.Hereinafter, filler 260 will be described in detail.

Referring to Fig. 2 B, upper substrate 212 is overlapping with lower substrate 211 in non-pad area NPA.Upper substrate 212 can be by having The glass or transparent plastic of excellent light transmittance are made, and make it possible to show the image realized by display element well.

Upper substrate 212 is attached to lower substrate 211 by sealant 213.Liquid crystal LC is filled by upper substrate 212,211 and of lower substrate The space that sealant 213 is formed.Sealant 213 is sealed between upper substrate 212 and lower substrate 211, with protection display member Part and route exempt to be affected by.

Cover glass 230 covers LCD MODULE 210, and can be by with excellent rigid glass or with thermoforming The plastics of property and good workability are made, to protect the component of LCD MODULE 210 from external impact, foreign matter or wet The influence of gas.

Clear binder 221 is between the upper substrate 212 and cover glass 230 of LCD MODULE 210 by cover glass 230 It is attached with LCD MODULE 210.Clear binder 221 can be by for the cured clear binder under ultraviolet (UV) line Acrylate-based composition is formed.Composition for clear binder may include such as acrylate base monomer, acrylic acid Ester group oligomer and UV sensitive initiator.

Prevent composition from overflowing when the composition for clear binder 221 is applied on upper substrate 212 every barrier 222 Stream.Every barrier by being made with the adjacent identical composition of transparent element 221.It is surrounded by the composition for clear binder The mode of the periphery of substrate 212 applies the composition and makes the composition solidification then to be formed every barrier 222.Exist every barrier 222 It is cured before forming clear binder 221.

Lower substrate 211 is attached to cover glass 230 by filler 260, and to the lower substrate 211 being applied in pad area PA On impact buffered.Therefore, filler 260 can also be referred to as cushion.As described above, in non-pad area NPA, under Substrate 211 and upper substrate 212 are overlapping, therefore LCD MODULE 210 has double board structures.On the other hand, in pad area PA In, lower substrate 211 is exposed only.That is, as shown in Figure 2 A, in pad area PA, showing 240 He of printed circuit board Touch printed circuit board 250 contacted with lower substrate 211 so that they on lower substrate 211 with driving chip DI and touch tablet TP Connection.Therefore, the upper surface of lower substrate 211 is exposed in pad area PA, and a side surface of lower substrate 211 is from upper The corresponding side surface of substrate 212 is prominent.

As shown in Figure 2 B, the thickness for the part of lower substrate 211 being exposed in pad area PA is less than cover glass 230 Thickness, so that lower substrate 211 is easily bent vulnerable to external impact, and than cover glass 230.The thickness and lid glass of filler 260 The distance between glass 230 and lower substrate 211 are corresponding, to minimize the bending of lower substrate 211 and to keep lower substrate 211 flat It is smooth.That is, the thickness of filler 260 can be with lid glass when the distance between cover glass 230 and lower substrate 211 change The distance between glass 230 and lower substrate 211 accordingly change.That is, filler 260 is that its elongation can adapt to lid glass The soft element of the distance between glass 230 and lower substrate 211 variation.The thickness of filler 260 is equal to cover glass 230 and lower substrate The distance between 211, so that filler is able to suppress lower substrate 211 and bends and keep lower substrate 211 flat.If lid The distance between glass 230 and lower substrate 211 change, then the thickness of filler 260 can change, so that the thickness of filler 260 Degree is equal to the distance between cover glass 230 and lower substrate 211.That is, filler 260 is its elongation with cover glass The change of the distance between 230 and lower substrate 211 and the soft element of adaptive change.

For example, the elongation of filler 260 can be 300% or higher.As used in this article, elongation refer to when to Certain material apply drawing force when the certain material deformation after the ratio between length and original length.When the elongation of filler 260 When being 300% or higher, even if changing in the distance in the manufacturing process of LCD device 200 between lower substrate 211 and cover glass 230 Become, due to the high elongation rate of filler 260, lower substrate 211 and cover glass 230 is caused also to be able to maintain and be attached together.It is another Aspect, if the elongation of filler, less than 300%, filler is possibly can not be with during the manufacturing process of LCD device The change of the distance between the cover glass and lower substrate that can occur and adaptive change.That is, even if cover glass and lower substrate The distance between change, the thickness for filling construction element also do not change.When this occurs, lower substrate can be because cover glass be under The distance between substrate length reduces and is bent towards cover glass.On the other hand, the upper limit value of the elongation of filler 260 does not have Especially limitation.Even if that is, in the case where needing distance of the filler between cover glass 230 and lower substrate 211 to change Also cover glass 230 and lower substrate 211 are attached to each other securely, thus the higher the better for the elongation of filler 260.

In addition, filler 260 has the elasticity modulus for being suitable for absorbing the impact for being applied to lower substrate 211.That is, filling out Filling object 260 is soft element, the soft element can make in the case where lower substrate 211 is deformed because of impact it is deformed under Substrate 211 is restored to its original-shape.

For example, the elasticity modulus of filler 260 is 9 × 10⁶Pa or lower.As used in this article, elasticity modulus refers to Certain material resists the resistance degree of tensile stress or compression stress, and be defined as certain material strain and stress it Than.Herein, the elasticity modulus of filler 260 refers to the elasticity modulus measured under room temperature (25 DEG C).If filler 260 Elasticity modulus is 9 × 10⁶Pa or lower, then filler 260 can absorb cover glass 230 and lower substrate 211 as rubber Between external impact.On the other hand, if the elasticity modulus of filler is greater than 9 × 10⁶Pa, then filler becomes hard element And it cannot be fully absorbed external impact, so that external impact can be transferred on lower substrate, to damage to lower substrate. On the other hand, the lower limit value of the elasticity modulus of filler 260 is not particularly limited.That is, working as the springform of filler 260 When measuring lower, filler 260 can absorb external impact well, and can be improved the durability of LCD device.Therefore, it fills out The lower the elasticity modulus for filling object 260 the better.

Filler 260 is formed by the composition for filler.For example, filler 260 can be by irradiating at ultraviolet (UV) Under cured acrylate based resin composition formed.

Fig. 3 is the method for illustrating the manufacture LCD device of an illustrative embodiments according to the present utility model Flow chart.Fig. 4 A to Fig. 4 E is the method for illustrating the manufacture LCD device of illustrative embodiments according to the present utility model Sectional view.

Referring to Fig. 3 and Fig. 4 A to Fig. 4 E, this method includes that the composition for being used for filler 461 is coated to liquid crystal display On the lower substrate 211 of module 210 (step S301).

As shown in Figure 4 A, what the part that composition 461 can be applied to the wherein upper surface of lower substrate 211 was exposed In pad area PA.For example, composition 461 can be applied on two angles of pad area PA.

Then, composition 461 is made to solidify (S302).This is referred to as solidifies for the first time.

Since the viscosity of composition 461 before solidifying is relatively low, composition 461 can be spread to uncoated composition 461 position.Composition 461 is gone through after being coated to be solidified for the first time, so that composition 461 does not diffuse into uncoated composition Position.Solidify the degree for referring to and 461 precuring of composition not being fully cured to composition 461 for the first time.By executing the The viscosity of one-step solidification, composition 461 is improved, so that composition 461 does not diffuse into undesirable region.

Then, it is applied to along the periphery painting of the upper substrate 212 opposite with lower substrate 211 of LCD MODULE 210 The composition (step S303) of bright adhesive.

Composition for clear binder can be applied to predetermined thickness along the periphery of upper substrate 212.For saturating The thickness and width of the composition of bright adhesive is not particularly limited, and can apply by suitable thickness and width, so that The composition 423 for clear binder for being coated to the central part of upper substrate 212 will not overflow.

Then, solidify the composition for clear binder on the periphery of upper substrate 212, to be formed every barrier 222 (step S304).

As previously mentioned, inhibit the composition for being coated to the clear binder of the central part of upper substrate 212 every barrier 222 423 overflows.Therefore, it is formed before coating composition 423 every barrier 222.Since lid glass will be attached in subsequent handling every barrier Glass 230, therefore be not fully cured every barrier 222.It can be according to mode precuring identical with composition 461 to increase every barrier 222 Its viscosity.

Then, coating composition 423, so that it is in the upper surface (step every the inside of barrier 222 covering upper substrate 212 S305)。

Can be with coating composition 423, so that its whole surface for covering upper substrate 212, but it can also be with coating composition 423, so that a part of its upper surface for only covering upper substrate 212, as shown in Figure 4 A.Due to coated composition 423 not yet solidify, therefore bonding force is weak and viscosity is very low.Composition 423 can be opened up on the upper surface of upper substrate 212 It opens, and is overflowed along what the periphery of upper substrate 212 was formed every 222 composite inhibitings 423 of barrier.

Then, cover glass 230 is set so that it covers LCD MODULE 210 (step S306).

Cover glass 230 can move under the action of the vacuum absorber of the upper surface for vacuum suction cover glass 230 To 210 top of LCD MODULE.Cover glass 230 can be made to be aligned so that the edge and LCD MODULE of cover glass 230 210 edge is parallel to each other.

Then, make cured 461 secondary curing of composition, to form the 260 (step of filler for attaching to cover glass 230 S307).This is referred to as second and solidifies.

As shown in Figure 4 B, cover glass 230 is pressed, so that for the composition of filler and the lower surface of cover glass 230 Contact.In this case, in order to increase cover glass 230 as wide as possible and for the contact surface between the composition of filler Product, excessively presses cover glass 230, and can make between the lower surface of cover glass 230 and the upper surface of lower substrate 211 Distance be reduced to be less than thickness of the composition when solidifying its first time for filler.Since cover glass 230 is excessive Pressing, therefore can be pressed by cover glass 230 every barrier 222, so that the thickness every barrier 222 can reduce.

When cover glass 230 is pressed, ultraviolet (UV) line is irradiated to the composition for filler, to for filling out The composition for filling object executes second and solidifies.Solidified by executing second, is used in the composition solidification of filler, and shape At and the filler 260 that is attached of cover glass 230 and lower substrate 211.Second solidify after filling construction element 260 with 9 × 10⁶Pa or smaller elasticity modulus, and there is 300% or higher elongation.

Then, the bubble between upper substrate 212 and cover glass 230 is removed, so that composition 423 is completely filled in upper substrate Between 212 and cover glass 230 (step S308).

As shown in FIG. 4 C, revocation is applied to the pressure of cover glass 230, and increases operation pressure.In doing so, it presses The suddenly change of power will cause composition 423 and extend throughout the whole surface of upper substrate 121.As described above, composition 423 can be with Cover the part of the upper surface of upper substrate 212 rather than the whole surface of upper substrate 212.Since clear binder is in the LCD of completion Cover glass 230 and LCD MODULE 210 are attached always in device 200, it is therefore necessary to increase clear binder as far as possible Bond area.Therefore, it is necessary to which the composition 423 for being used in clear binder is unfolded, so that covering before the solidification of composition 423 Cover the whole surface of substrate 212.When the pressure for being applied to cover glass 230 is revoked and operation pressure increases suddenly, group Object 423 is closed to be unfolded on upper substrate 212 due to pressure suddenly change.

It is compressed every barrier 222 due to the screen resilience every barrier 222 when the pressure for being applied to cover glass 230 is revoked Thickness can return to original thickness.When this occurs, cover glass 230 can increase with the thickness every barrier 222 And ramp up, and and cover glass 230 be attached filler 260 in generate tensile stress.However, as previously mentioned, Since the elongation of filler 260 is high, even if cover glass 230 ramps up, filler 260 can also be filled in always lid Between glass 230 and lower substrate 211, the adherency between cover glass 230 and lower substrate 211 is maintained.

If the elongation of filler is low, filler is increased also with cover glass.Because the thickness of filler is due to filling out It fills the low elongation of object and keeps constant, so lower substrate and filler attachment part can increase as filler increases And it is bent.When this occurs, lower substrate can be bent, so that the orientation of some liquid crystal can tilt.As a result, can be from inclined Light leakage in liquid crystal.However, since the filler 260 of the LCD device 200 of illustrative embodiments according to the present utility model has There are 300% or higher high elongation rate, therefore even if cover glass 230 is increased, filler 260 due to the screen resilience every barrier 222 Thickness can also increase and the distance between cover glass 230 and lower substrate 211 can be made to be maintained.Therefore, can press down Lower substrate 211 processed bends and reduces light leakage.

Meanwhile in the process that composition 423 is unfolded on the upper surface of upper substrate 212, composition 423 is possibly can not It is sufficient filling between upper substrate 212 and cover glass 230, so that bubble VO can be generated.If composition 423 is with bubble VO It is cured, then cover glass 230 and LCD MODULE 210 can not be firmly attached together.In addition, if depositing in the display area In bubble VO, then the visuality of LCD device 200 can be deteriorated due to bubble VO.Therefore, it is necessary to be cured it in composition 423 The preceding process for executing the bubble VO between removal composition 423 and cover glass 230.It can be by the way that LCD device 200 be exposed to height The process that temperature executes bubble removing VO up to predetermined period.

In the process for removing bubble removing VO, hot environment is exposed to up to predetermined amount of time by filler 260 and every barrier 222, Therefore they can be expanded.Specifically, it is possible to expand every the corner of barrier 222.This is because forming the process every barrier 222 The composition of relatively great amount of clear binder is coated on corner by period.Specifically, pass through the periphery painting along upper substrate 212 It is applied to the composition of clear binder and is solidified to be formed every barrier 222.However, being applied to clear binder applying During the process of composition, composition can be applied to the corner of upper substrate 212, this is unwanted.When this thing happens When, the thickness every the corner of barrier 222 can be greater than the thickness of other parts.In addition, when being expanded in the high temperature environment every barrier 222, It can be expanded than other parts every the corner of barrier 222 more.As a result, during the process for removing bubble removing VO, every the thickness meeting of barrier 222 Become uneven.

Because can become unevenly every the thickness of barrier 222, LCD MODULE 210 is relative to the flat of cover glass 230 Smooth upper surface can tilt, so that the touch performance of LCD device 200 can deteriorate.Specifically, in recent years, detection touching is being studied Touch the three-dimensional tactile detection technology of the coordinate of input and the intensity of touch input.The intensity of touch input can be by pressure sensing Device senses, and pressure sensor senses the intensity of touch input by the air gap variation above sense pressure sensor.Pressure Sensor can be set below LCD MODULE 210.For example, pressure sensor can be set with LCD MODULE Below the back light unit of 210 connections.If every the in uneven thickness of barrier 222, cover glass 230 and LCD MODULE 210 it Between distance can become unevenly so that flat upper table of the lower surface of LCD MODULE 210 relative to cover glass 230 Face can tilt.When this occurs, the back light unit below LCD MODULE 210 is arranged in also to tilt, so that backlight Gap between unit and pressure sensor can become uneven.When the gap between back light unit and pressure sensor becomes not When consistent, the air gap above pressure sensor can also change.As a result, pressure sensor can not accurately measure the strong of touch input Degree, and the touch performance of LCD device 200 can deteriorate.

In addition, LCD device 200 is being moved into hot room to go in the process of bubble removing VO, cover glass 230 and liquid crystal display Between module 210 to will definitely mismatch.That is, because the composition for clear binder 423 has before it is cured There is weak bonding force, so cover glass 230 cannot be attached to upper substrate 212 by it.In addition, cover glass 230 passes through filler 260 Attach to lower substrate 211.However, filler 260 possibly can not be protected effectively since the elasticity modulus of filler 260 is low Hold the alignment between cover glass 230 and lower substrate 211.That is, when cover glass 230 deviates during LCD device 200 is mobile When with the alignment of lower substrate 211, the screen resilience of filler 260 may be not enough to restore between cover glass 230 and lower substrate 211 Alignment.

It is not right between thickness inconsistence problems and cover glass 230 and lower substrate 211 in order to solve LCD device 200 Quasi- problem, the method for the manufacture LCD device of an illustrative embodiments according to the present utility model make LCD MODULE 210 realign with cover glass 230.

Specifically, it in the method for the manufacture LCD device of an illustrative embodiments according to the present utility model, is pressing Gland glass 230 makes compressed simultaneously every barrier 222 alignment (step between adjusting cover glass 230 and upper substrate 212 S309)。

It can be used for by illustrative embodiments according to the present utility model by LCD MODULE and cover glass pair Quasi- alignment device executes realigning between cover glass 230 and upper substrate 212.It is retouched below with reference to Fig. 5 A to Fig. 5 F State the configuration of LCD MODULE and alignment device.Hereinafter, it will be described in cover glass 230 and LCD MODULE 210 The process realigned.

Firstly, as shown in fig.4d, cover glass 230 and LCD MODULE 210 are arranged on bearing unit 490.Branch Bearing unit 490 is configured as the lower substrate 211 of vacuum suction LCD MODULE 210, and makes LCD MODULE 210 in x- It is moved in y plane.

Then, by pressure unit 470 press cover glass 230 with every the corresponding part in corner of barrier 222 so that every barrier It is compressed in 222 corner.As previously mentioned, during the process of the bubble in removal composition 423, every the corner of barrier 222 Excessively expansion.The pressing of unit 470 press every the corner of barrier 222 excessively expanded, to keep the thickness every barrier 222 almost the same. Press unit 470 with the power of 40gf to 200gf pressing cover glass 230 with every the corresponding part in the corner of barrier 222 so that every The thickness of barrier 222 keeps almost the same.If the pressing force for the unit 470 that presses is less than 40gf, may ratio every the corner of barrier 222 Other parts are thick, this is undesirable.On the other hand, if the pressing force of pressure unit 470 is greater than 200gf, every barrier 222 Corner may be thinner than other parts, this is also undesirable.

It is then possible to the position of mobile bearing unit 490, to be directed at cover glass 230 with LCD MODULE 210. Due to the lower substrate 211 of 490 vacuum suction LCD MODULE 210 of bearing unit, the position of LCD MODULE 210 can To be moved with bearing unit 490.When cover glass 230 and LCD MODULE 210 pass through the filler with low elastic modulus 260 when being attached together, and LCD MODULE 210 can change relative to the position of cover glass 230.

Then, ultraviolet light is irradiated on cover glass 230 so that composition 423 in cover glass 230 and upper substrate 212 Between it is partially cured.Ultraviolet light is irradiated to composition 423 by transparent cover glass 230.Composition 423 is partially cured, makes It obtains upper substrate 212 and cover glass 230 is attached together in some regions.

Then, solidify the composition 423 being filled between cover glass 230 and upper substrate 212, so that 230 He of cover glass LCD MODULE 210 is attached together (step S310).

As shown in figure 4e, pressure unit is separated with cover glass 230, and irradiates cover glass 230 with ultraviolet light, to use Solidify in the composition of clear binder.As described above, because cover glass 230 and upper substrate 212 are by making in some regions Composition solidifies to be attached together, so even if cover glass 230 also can be with liquid crystal display after withdrawing pressure unit Module 210 is aligned.In addition, the thickness every the corner of barrier 222 can also keep being compressed.Therefore, cover glass 230 can kept The composition solidification of clear binder is used in while alignment between LCD MODULE 210, and every the thickness of barrier 222 Degree keeps almost the same.

It is used in the composition solidification of clear binder, to form clear binder 221.Although every barrier 222 and transparent viscous Mixture 221 is shown as different elements in Fig. 4 E, but every barrier 222 and clear binder 221 by being used for clear binder Same combination formed, therefore when the composition for clear binder is cured, clear binder 221 and every barrier 222 It is formed single attaching components.

As previously mentioned, filler 260 has low elasticity modulus, therefore the impact for being applied to LCD device 200 can be with It is filled the absorption of object 260.Specifically, although thin lower substrate 211 is exposed in pad area PA, with low elastic modulus Filler 260 is arranged between cover glass 230 and lower substrate 211, therefore the impact being applied in pad area PA can be filled Object 260 absorbs.Therefore, it can be improved the durability of LCD device 200.

In addition, cover glass 230 can attached to liquid crystal display since filler 260 has high elongation Lower substrate 211 is inhibited to be bent during the process of module 210.That is, even if between lower substrate 211 and cover glass 230 away from From change, the thickness of filler 260 can also become to be equidistant with this, and cover glass 230 is allowed to attach to lower base always Plate 211.

On the other hand, in fact it could happen that following problems: alignment between cover glass 230 and LCD MODULE 210 may be by In filler 260 low modulus and high elongation rate and mismatch again.However, in illustrative embodiments according to the present utility model Manufacture LCD device method in, the alignment between cover glass 230 and LCD MODULE 210 is readjusted, and is thus inhibited Alignment mismatch between cover glass 230 and LCD MODULE 210.

In addition, can excessively expand every the corner of barrier 222, thus make during the process of the bubble in removal composition 423 Become non-uniform problem at the thickness every barrier 222.In this respect, in the system of illustrative embodiments according to the present utility model It makes in the method for LCD device, every the corner of barrier 222 and keeps the part of composition 423 solid by using the pressing of pressure unit 470 Change, allows and be consistent every the thickness of barrier 222.In this way it is possible to which it includes defeated for sensing touch for reducing in manufacture The defect that may occur during the process of the LCD device 200 of the pressure sensor of the intensity entered.
