Embodiment
Hereinafter with reference to relevant drawings, curved face display panel and manufacture method thereof according to preferred embodiment of the present invention are described, wherein components identical will be illustrated with identical reference marks.
Fig. 1 is the manufacture method of the curved face display panel of preferred embodiment of the present invention, and it comprises step S01～S05.Below with Fig. 1 and other description of drawings manufacture methods of arranging in pairs or groups.
Please refer to shown in Figure 2ly, step S01 is for providing a display module 1 with a glass support plate 111 or 121.Hereinafter, glass support plate 111 will be called first glass support plate, and glass support plate 121 will be called second glass support plate.Display module 1 of the present invention is not limited to any kind of, gets final product so long as have glass support plate, for example is LCD MODULE, Organic Light Emitting Diode display module, Electronic Paper display module or light-emitting diode display module.The display module 1 of present embodiment is to be example with the LCD MODULE.
In the present embodiment, provide the step S01 of display module 1 more to comprise the upright two substrates 11,12 of group, and a liquid crystal layer 13 is set between two substrates.In addition, step S01 more comprises the manufacture craft of first and second glass support plate 111,121 of attenuate, makes first and second glass support plate 111,121 have pliability.Certainly, if first and second glass support plate 111,121 originally has pliability, can omit this attenuate manufacture craft; In addition present embodiment also can be only one of them imposes the manufacture craft of attenuate at first glass support plate 111 and second glass support plate 121.At this, first and second glass support plate 111,121 all is thinned to its thickness smaller or equal to 0.2mm.The manufacture craft of glass support plate attenuate can be implemented by chemical mode and/or physics mode, wherein chemical mode such as dry ecthing, wet etching, physics mode as grind, polishing, chemistry and physics mode such as chemically mechanical polishing (Chemical-Mechanical Polishing, CMP).
As shown in Figure 3, step S02 is for providing one first fixing base 2.In the present embodiment, first fixing base 2 is a transparent substrates and is a flexible base plate, can be tabular or sheet.The material of first fixing base 2 can comprise plastic cement, polyethylene terephthalate (Polyethylene Terephthalate for example, PET), polycarbonate (Polycarbonate, PC), polystyrene (Polystyrene, PS) or acryl (Polymethyl Methacrylate, PMMA).In addition, first fixing base 2 can have a microstructure 21, and microstructure 21 for example is micro concavo-convex structure, lenticule, multicoating, in order to the light path that changes light and reach scattered beam or purpose such as concentrated light.Microstructure 21 also can be functional layer, for example reaches anti-scratch, uvioresistant or the anti-function such as trace that refers to.The microstructure 21 of present embodiment is an example with the micro concavo-convex structure.In addition, first fixing base 2 can add scattering particle and make.
Fig. 4 is the synoptic diagram of the step S03～S05 among Fig. 1, wherein, step S03 is contraposition first glass support plate 111 and first fixing base 2, and step S04 is bonding first glass support plate 111 and first fixing base 2, step S05 is crooked first fixing base 2, so that display module 1 is together crooked.
In the present embodiment, first fixing base 2 can pass through a contraposition board and 111 contrapositions of first glass support plate, after the contraposition, first glass support plate 111 is adhered on first fixing base 2.In the present invention, except use single bonding material carry out bonding, also can use bonding material to carry out bonding with a plurality of glue materials.
As shown in Figure 5, the bonding material 3 of present embodiment comprises a band of glue 31 and a watery glue 32.In the present embodiment, the refractive index of band of glue 31 and/or watery glue 32 can be similar to the refractive index of glass.At this, band of glue 31 for example is that (glue of octyl-α-Cyanoacrylate), watery glue 32 for example is SVR glue to OCA.
On manufacture craft, can by roller band of glue 31 be arranged on first fixing base 2 earlier, more watery glue 32 is arranged on the band of glue 31.And then by band of glue 31 and watery glue 32 gluings, first fixing base 2 and first glass support plate 111.Certainly, the other practice also can be arranged at band of glue 31 on first glass support plate 111 of display module 1, watery glue 32 is set again on band of glue 31, and bonding first glass support plate 111 and first fixing base 2.
Present embodiment can solve the problem of only using single glue material to produce on the manufacture craft by band of glue 31 and the 32 mutual collocation of watery glue.Though the viscosity of band of glue 31 is stronger,, between first glass support plate 111 and first fixing base 2, form bubble easily if only use band of glue.In addition, when using band of glue bonding, need to locate relative position between first fixing base 2 and first glass support plate 111 by absorption, and suction damage easily behind the attenuate first glass support plate 111 and on element.In addition, phenomenon is peeled off in easy generation though watery glue 32 bonding backs are difficult for the generation bubble, and its viscosity is more weak.So present embodiment is directly to contact with first glass support plate 111 by watery glue 32, most band of glue 31 does not directly contact with first glass support plate 111, thereby can avoid bubble to produce, in addition, watery glue 32 can come reinforcement viscosity by band of glue 31, thereby avoids peeling off phenomenon.
Referring again to shown in Figure 4, bonding after, force in first fixing base 2 and make its bending so that the display module 1 that is adhered to first fixing base 2 is together crooked, and form a curved face display panel P1.In the present embodiment, be by forcing in the both ends of the surface of first fixing base 2, and make it be curved to the one radius-of-curvature between between the 10mm to 500mm, and first fixing base 2 can be bent into a concave surface (Concave) or a convex surface (Convex) towards a surface of display module 1, is to be example with the concave surface at this.Certainly, first fixing base 2 also can be bent to the combination of concave surface and convex surface towards the surface of display module 1, and the present invention does not limit this.
In curved face display panel P1, first glass support plate 111 has one first flexure plane C1, and first fixing base 2 has one second flexure plane C2, and two flexure plane C1, C2 are oppositely arranged, and binds mutually by bonding material 3.The radius-of-curvature of the first flexure plane C1 and the second flexure plane C2 is between between the 10mm to 500mm.The first flexure plane C1 and the second flexure plane C2 are the combination of a concave surface and a convex surface, and in this, the first flexure plane C1 is a convex surface, and the second flexure plane C2 is a concave surface.In addition, the microstructure 21 of first fixing base 2 is positioned at the surface of first fixing base 2 back to the second flexure plane C2.
After bending, manufacture method can more comprise solidifies bonding material 3, can be implemented according to the curing characteristics of bonding material 3 at this, for example if bonding material 3 is optic-solidified adhesive or heat-curable glue, can impose photocuring or heat curing.After solidifying, two polaroids (figure shows) can be arranged at respectively on the surface of second glass support plate 121 of second substrate 12 and first fixing base 2; Certainly, polaroid also can be arranged at respectively on the surface of first and second glass support plate 111,121 after first and second glass support plate 111,121 of attenuate.
What deserves to be mentioned is, because the refractive index of band of glue 31 and/or watery glue 32 is similar to the refractive index of glass, so can avoid light between the first flexure plane C1 and the second flexure plane C2, to produce the refraction of wide-angle, so can promote the brightness of curved face display panel P1.
