Embodiment

Describe in detail below with reference to accompanying drawings according to flat display board of the present invention and attached to the preferred embodiment of diaphragm on the flat display board and polaroid lamination.

[first embodiment]

The polaroid lamination that first embodiment is attached to its LCD panel and is attached to this LCD panel at polaroid in the flat display board.

Fig. 1 is the sectional view according to the LCD panel of the first embodiment of the present invention; Fig. 2-5 shows the sectional view according to the various examples of diaphragm of the present invention, and Fig. 6 and 7 is respectively and shows according to the present invention polaroid lamination LCD panel attached thereto and the view of the difference between the prior art.

LCD (LCD) comprising: the LCD panel that is used to show required image thereon according to picture signal by the amount of the light of adjusting transmission; Comprise that light source, optical sheet, optical plate or diffusion sheet, reflector plate etc. are to provide the back light unit of light to the LCD panel; And molded frame, be used to put the upper frame and the underframe of panel and back light unit.The LCD panel is finished by this way, makes that reflector plate, light source, optical plate or orders such as diffusion sheet, optical sheet are stacked and is installed in underframe and the molded frame; LCD panel position thereon; And the last covering of upper frame thereon.Each element is made respectively and is assembled in the LCD panel then.

With reference to Fig. 1, comprise that according to the LCD panel 100 of the first embodiment of the present invention public electrode and color filter form thereon filter substrate 110, have a large amount of formation thin film transistor (TFT) (TFT) substrate 120 and polaroid 200 and 220 such as the on-off element of TFT thereon.Element, pattern, electrode etc. are formed on each surface of filter substrate 110 and TFT substrate 120 by some vapor depositions, exposure and etch process, and both alignment layers forms thereon then.Liquid crystal layer 115 is inserted in by the edge with filter substrate 110 and TFT substrate 120 and is bonded to each other in the formed space, and upper and lower polaroid 200 and 220 is respectively on the surface, upper and lower attached to the substrate 110 of combination and 120.

If voltage is applied to the filter substrate 110 that is formed on LCD panel 100 and the electrode on the TFT substrate 120, the liquid crystal molecule reorientations that are inserted in the liquid crystal layer 115 between the substrate make desired image to show at the LCD panel with shielding or transmission from the light that back light unit produces.At this moment, because only the light that vibrates along specific direction can pass through upper and lower polaroid 200 and 220, polaroid allows the liquid crystal layer 115 control optical transmissions between filter substrate 110 and the TFT substrate 120.That is, polaroid 200 and 220 has and is absorbed in the light that vibrates on the specific direction and transmission along the effect perpendicular to the light of the direction vibration of this specific direction.

Shown in the amplifier section of Fig. 1, upper polarizing sheet 200 comprises polarizer 204 and supporting layer 202 and 202.Polarizer 204 is by along a direction stretching polyethylene alcohol (PVA) and soak this film and make in iodine (I2) and dichromatic dye (dichromatic dye) solution.Iodine and dye molecule are arranged parallel to each other on draw direction.Because iodine and dye molecule show double-colored characteristic, they have the effect that is absorbed in the light that the light that vibrates on the draw direction and transmission vibrate on the direction perpendicular to draw direction.

Polarizer 204 uses at the state of non-heat fixation, and iodine can volatilize because if polarizer is stretched/arranges thermosetting rule then.Therefore, because according to the variation of environment temperature or humidity and widely elongation or compression and have weak physical strength of polarizer 204 for transmission direction (transmission direction), for the effective width that reduces polarizer 204 with restriction because the distortion that the variation of temperature and humidity causes needs supporting layer 202 and 202.Supporting layer 202 and 202 is made by Triafol T (TAC).In addition, bonding coat 209 is formed on and makes between filter substrate 110 and the supporting layer 202 that upper and lower polaroid 200 and 220 can be respectively on the outside surface attached to the TFT substrate 120 of filter substrate 110 and LCD panel.

Retardation layer further is inserted between LCD panel 100 and the upper polarizing sheet 200 being converted to linearly polarized photon owing to the elliptically polarized light that the delay that produces in the light that penetrates the LCD panel causes.The uniaxial orientation film of being made by polycarbonate is used as phase shift films.

If the supporting layer of being made by Triafol T is layered on the outermost part of top polarizing coating 200, exterior light is directly towards spectators' reflection, so spectators may feel to dazzle the eyes.That is, when spectators watch the LCD panel from the outside, such as the exterior light of sunlight or interior lighting light from supporting layer 202 reflections and reflected light directly towards spectators' eyes, so spectators' recognition graph picture clearly.For preventing this point, be used to restrain the outermost surfaces that further is formed on upper polarizer 200 from the antiglare layer 206 of the dazzle of polaroid.Be mapped to the light of its lip-deep light minimizing thereby be reflected into to antiglare layer 206 diffusions from the specific direction reflection.

Simultaneously, lower polarizing sheet 220 can be made of polarizer, supporting layer and antiglare layer in the same manner with upper polarizing sheet 200.Perhaps, lower polarizing sheet 220 can only be made of polarizer and supporting layer and not have an antiglare layer.Have in the situation of lower polarizing sheet 220 of antiglare layer the inconvenient part that does not have upper and lower polaroid 200 and 220 to distinguish mutually, but the shortcoming that exists the unit cost of lower polarizing sheet 220 to increase in use.On the other hand, do not provide in the situation of antiglare layer in lower polarizing sheet 220, the unit cost of polaroid reduces but inconvenient part is that upper and lower polaroid 200 and 220 should distinguish mutually.

In addition, upper and

lower diaphragm

300 and 320 is respectively on the outermost surfaces attached to polaroid 200 and 220.When LCD panel 100 experienced such as various technologies such as trouble shooting technology, TAB technology, PCB technologies, the surface of

diaphragm

300 and 320 protection polaroids avoided being abraded by exterior materials.When LCD panel and back light unit, molded frame, upper frame, underframe etc. were assembled together,

diaphragm

300 and 320 was removed.

For this reason, the upper protective film 300 that is attached to upper polarizer 200 comprises basement membrane 304, is formed on the basal surface of basement membrane 304 to allow upper protective film to be attached to the removable bonding coat 302 of upper polarizer 200 and to be formed on the antiglare layer 306 that is used for diaphragm on the upper surface of basement membrane 304.Basement membrane 304 is by making such as the transparent polymeric resin of polyethylene terephthalate resin, polyolefin resin, alkyd resin, polyacrylic resin or polycarbonate resin.In the present embodiment, preferred use have the high grade of transparency, good mechanical strength, good processibility and the polyethylene terephthalate resin of strong permanance.

Bonding coat 302 is by comprising that the material with bonding gelatin polymer (gel-polymer) material of oneself makes.Bonding coat 302 can comprise the elastic body based on alkene.The cohesive of bonding coat 302 can be adjusted so that when LCD panel and back light unit, molded frame, upper frame, underframe etc. are assembled together diaphragm 300 can be separated and remove.Especially, the surface of preferred upper polarizing sheet 200 should not be compromised when diaphragm 300 is separated.In addition, preferably bonding film 302 has and can easily adhere to once more after so good cohesive makes it separated.

Be reflected into to antiglare layer 306 diffusions and be mapped to its lip-deep light to reduce from the light of specific direction reflection.For preventing its lip-deep dazzle, the light that reflects on the surface of antiglare layer 306 disappears mutually, and ground is mutual interferes feasible low reflection to realize from the teeth outwards.

For this reason, the scattering particles 308 such as spherical silica or granules of polystyrene that are used for the incident light of diffusion ground reflection on it are included in the antiglare layer 306.Antiglare layer 306 can form by this way, and promptly scattering particles 308 apply on basement membrane 304 with gel state, and bonding coat 302 is formed on its lower surface with acryl resin, PET etc.Wherein the diaphragm 300 of the antiglare layer 306 that forms by this way is shown in Figure 2.At this moment, bonding coat 302 can be formed on the antiglare layer 306 rather than on the basement membrane 304.

On the other hand, Fig. 3 to 5 shows some examples with the diaphragm of multi-form formation.

As shown in Figure 3, diaphragm 300a makes by this way: scattering particles 308 and polyethylene terephthalate (PET) are mixed making basement membrane 304a, and bonding coat 302 is formed on the lower surface of basement membrane.That is, basement membrane 304a is also with the antiglare layer that acts on diaphragm.At this moment, basement membrane 304a is preferably made by polyethylene terephthalate, but can be used such as the transparent polymeric resin of polyolefin resin, alkyd resin, polyacrylic resin or polycarbonate resin.In addition, above-mentioned spherical silica or granules of polystyrene can be used as scattering particles 308.

Simultaneously; as shown in Figure 4; replace to use the scattering particles such as silica or granules of polystyrene, can use diaphragm 300b, wherein bonding coat 302 is formed on the basal surface of basement membrane 304b and the top surface of diaphragm is the irregular surface 305b with band diffuse reflection pattern by surface treatment.

Another example of diaphragm 300c obtains by the above-mentioned example of mutual combination.As shown in Figure 5, diaphragm 300c by basement membrane 304, be coated in the bonding coat 302 that comprises the antiglare layer 306c that is used for diaphragm of scattering particles 308 on the top surface of basement membrane 304 and be formed on the basal surface of basement membrane 304 and form.Here, the top surface of antiglare layer 306c can be treated to the irregular surface 307c with band diffuse reflection pattern.Such irregular surface can be applied to diaphragm 300a shown in Figure 3.That is, the top surface that wherein comprises the basement membrane 304a of scattering particles 308 forms the irregular surface 307c with diffuse reflection pattern.

Simultaneously, following diaphragm 320 can be made up of basement membrane, bonding film and the antiglare layer that forms in the same manner with upper protective film 300.Perhaps, following diaphragm 320 can be made of basement membrane and bonding coat and not have antiglare layer.Have in the situation of following diaphragm 320 of antiglare layer in use, do not have upper and lower diaphragm 300 and the 320 inconvenient parts that should be distinguished mutually, increase but shortcoming is down the unit cost of diaphragm 320.On the other hand, descending diaphragm not provide the situation of the antiglare layer that is used for diaphragm, the unit cost of diaphragm reduces, but inconvenient part is that upper and

lower diaphragm

300 and 320 should distinguish mutually.

Next, be described in when making the trouble shooting that has polaroid LCD panel attached thereto in the LCD process according to the present invention and the difference between the LCD panel of prior art with reference to Fig. 6 and 7.

As shown in Figure 6, check by this way that promptly the examiner observes by back light unit and produces the fault that the light A that penetrates LCD panel 100 then checks LCD panel 100 according to the LCD panel 100 of the first embodiment of the present invention.At this moment, if exterior light B incides the upper protective film 300 corresponding to the outermost surfaces of LCD panel 100, because the almost cancellation of reflected light C of the diffuse reflection exterior light B of the antiglare layer 306 by upper protective film 300.The eyes that the light A that like this, is only produced and penetrated LCD panel 100 by back light unit enters the examiner make the fault of LCD panel 100 accurately to detect.

On the other hand; in the wherein general situation of diaphragm 30 as shown in Figure 7 attached to the traditional LC D panel 10 of polaroid 200; when the examiner detects the fault of LCD panel 10, not only produce and penetrate the light A of LCD panel 10 but also also have the reflected light D of exterior light B to enter examiner's eyes by back light unit.Therefore, because the glare phenomenon examiner can not detect the fault of LCD panel 10 exactly.That is, because traditional general diaphragm 30 directly reflects exterior light B, the strong mistake of the intensity of reflected light D is by the intensity of the reflected light C of upper protective film of the present invention shown in Figure 6 300 generations.Therefore, because strong exterior light D has unnecessarily entered examiner's eyes, detectability reduces.

Usually; in the situation of polaroid attached to the outside surface of LCD panel; the LCD panel manufacturers receives the folded lamination of polaroid from polaroid manufacturer, and wherein diaphragm is attached to polaroid, thereby and adheres to the outside surface of LCD panel with the lamination that the folded lamination of required size cutting polaroid will cut.For this reason, polaroid manufacturer produces the polaroid lamination that diaphragm is not only arranged but also barrier paper attached thereto is arranged.

That is, as shown in Figure 8, polaroid lamination 400 comprises polaroid 200 and the diaphragm 300 of so constructing, and on the basal surface of barrier paper 250 attached to polaroid 200.The undermost bonding coat 209 that barrier paper 250 is attached to corresponding to polaroid 200 is attached to filter substrate 110 up to polaroid 200 by bonding coat 209 with protection bonding coat 209.That is, barrier paper 250 adhere to temporarily with prevent bonding coat 209 in common treatment state contaminated and be exposed to outside.Therefore, barrier paper 209 can be with the roller State Control when producing the polaroid lamination in enormous quantities.Preferably when barrier paper 250 with suitable power when upper polarizer 200 is removed, the bounding force of the bonding coat 209 of upper polarizer 200 should not be reduced.In addition, preferably barrier paper 250 has good bounding force and makes separated or remove the back it can easily be adhered to once more.Such as the sheet of plastic foil, sheet rubber, paper, cloth or nonwoven fabrics, with suitable separant promptly based on the separant of silicones, based on chain alkyl (alkyl) separant, fluorine separant or if necessary apply with molybdenum sulphide, can be used as barrier paper 250.
