Embodiment
Figure 1A to Fig. 1 D is the manufacturing process schematic diagram of electronic installation according to an embodiment of the invention.Please also refer to Figure 1A, first provide the first device substrate 100 and the second device substrate 200.Particularly, the electronic installation be made up of the first device substrate 100 and the second device substrate 200 has active region A and the surrounding zone P (as shown in Figure 2) around active region A.
In the present embodiment, the first device substrate 100 can be display panel, and it is such as the display panel of display panels, organic electroluminescence display panel, electrophoretic display panel or other kind of form.Second device substrate 200 can be contact panel, and it is such as the contact panel of capacitance type touch-control panel, electric resistance touch-control panel, optical touch control panel or other kind of form.So, the present invention is not limited thereto, according to other embodiment, the first device substrate 100 can also be other device substrate.Second device substrate 200 also can be other device substrate, such as, be protective lens (cover lens).
According to the present embodiment, the first device substrate 100 is display panels, and it comprises infrabasal plate, upper substrate and the display medium between upper substrate and infrabasal plate.In general, infrabasal plate can be described as again array of pixels substrate, and it comprises multiple dot structure, and each dot structure comprises sweep trace, data line, active member and pixel electrode.Upper substrate can be described as subtend substrate or colored optical filtering substrates, its substrate that can be blank substrate, be provided with the substrate of electrode or be provided with chromatic filter layer.Therefore, for the first device substrate 100, active region A can be described as viewing area again, and surrounding zone P can be described as again drive circuit area or perimeter circuit district.
Second device substrate 200 is contact panel.According to the form (capacitance type touch-control panel, electric resistance touch-control panel or optical touch control panel) of contact panel, element set in the second device substrate 200 is not quite similar.Because described contact panel can be the known capacitance type touch-control panel of any one, electric resistance touch-control panel or optical touch control panel, therefore, do not repeat them here the element in contact panel.For the second device substrate 200, active region A can be described as Touch Zone again, and surrounding zone P can be described as again perimeter circuit district.
Afterwards, coated optical liquid glue material 300 (Optically Clear Liquid Adhesives, OCLA) between the first device substrate 100 and the second device substrate 200, and the optical liquid rubber material 300 of coating is mainly arranged in active region A.Particularly, optical liquid rubber material 300 is the hardenable glue material of irradiation, such as, be the hardenable liquid glue material of irradiating ultraviolet light.In addition, described optical liquid rubber material 300 preferably has the penetrability of more than 90% before unhardened, and the optical liquid rubber material of the penetrability of tool more than 97% after curing, this is because optical liquid rubber material 300 can be coated in the A of active region, therefore optical liquid rubber material 300 need have the image display quality that sufficiently high penetrability just can not affect electronic installation.In the present embodiment, the material of optical liquid rubber material 300 is such as the optical liquid rubber material of the model 08A21x-17 that Sony produces.
The method of the active region A coated optical liquid glue material 300 between the first device substrate 100 and the second device substrate 200 can be any one coating processes known, and can be at the first device substrate 100 coated optical liquid glue material 300 or at the second device substrate 200 coated optical liquid glue material 300.According to an embodiment, between the first device substrate 100 and the second device substrate 200, the method for coated optical liquid glue material 300 is first at the second device substrate 200 coated optical liquid glue material 300, afterwards, the second device substrate 200 is turn to the subtend or top that are positioned at the first device substrate 100.Now, optical liquid rubber material 300 can drip toward the first device substrate 100 and first contact as small size with the first device substrate 100 because of gravity factor, then along with the carrying out of diffusion process (pressing program), progressively increase the contact area of optical liquid rubber material 300 and the first device substrate 100, optical liquid rubber material 300 is spread gradually from inside to outside, contributes to the air of optical liquid rubber material 300 periphery to discharge.
After active region A coated optical liquid glue material 300 between the first device substrate 100 and the second device substrate 200, please refer to Figure 1B, photomask 400 is set above the second device substrate 200.Particularly, as shown in Figure 1B and Fig. 3, photomask 400 has photic zone 402 and alternatively non-transparent district 404.The corresponding surrounding zone P in photic zone 402 is arranged, and the corresponding active region A in alternatively non-transparent district 404 is arranged.According to the present embodiment, the photic zone 402 of photomask 400 has outward flange 402a and inward flange 402b.Outward flange 402a is preferably aligned in the side edge of the first device substrate 100.Inward flange 402b is positioned at surrounding zone P or is positioned on the border of surrounding zone P and active region A, make optical liquid rubber material 300 in the P of surrounding zone or leading differential hardening on the border being positioned at surrounding zone P and active region A, with the outside preventing the optical liquid rubber material 300 not yet hardened from overflowing to the first device substrate 100 and/or the second device substrate 200.At this, the width of the photic zone 402 of described photomask 400 between 2 time and 100 time between.And in practice, the width of photic zone 402 need exceed the side edge of the first device substrate 100 and/or the second device substrate 200, therefore can change along with the size of the first device substrate 100 and/or the second device substrate 200.
Then, carry out optical liquid rubber material diffusion process, spread from active region A toward surrounding zone P to make optical liquid rubber material 300.Particularly, in time carrying out described optical liquid rubber material diffusion process, use photomask 400 to carry out the first irradiation program 600 more simultaneously, when diffusing to surrounding zone P to make optical liquid rubber material 300, can differential hardening be produced.
In the present embodiment, described optical liquid rubber material diffusion process further comprises and carries out pressing program 500 to the first device substrate 100 and the second device substrate 200.In other words, in the present embodiment, this optical liquid rubber material diffusion process can bestow pressing pressure in the direction toward the first device substrate 100 on the second device substrate 200, spreads from active region A toward surrounding zone P to make optical liquid rubber material 300.When carrying out described pressing program 500, use photomask 400 pairs of optical liquid rubber materials 300 to carry out the first irradiation program 600 more simultaneously.According to a preferred embodiment, the wavelength of light that the first above-mentioned irradiation program 600 uses is 300 ~ 400nm, and illumination intensity is 3600 ~ 5400mW/cm
2, the irradiation time was 1.6 ~ 2.4 seconds.
Light due to the first irradiation program 600 only can be perforated through the photic zone 402 of photomask 400, and therefore diffusing to can because be irradiated by light and differential hardening corresponding to the optical liquid rubber material 300 in photic zone 402.In more detail, the optical liquid rubber material 300 diffused in photic zone 402 can produce the change of some physical propertys gradually because of being irradiated to by light.For example, the hardness and the viscosity that diffuse to the optical liquid rubber material 300 in photic zone 402 can increase along with light irradiation time, therefore, rate of propagation will reduce gradually, until optical liquid rubber material 300 differential hardening diffused in photic zone 402 and stop diffusion and flowing.And the optical liquid rubber material 300 of correspondence in alternatively non-transparent district 404 is owing to can not be irradiated to by light, therefore the corresponding optical liquid rubber material 300 being arranged on alternatively non-transparent district 404 can continue to surrounding flowing and diffusion in the process of optical liquid rubber material diffusion process, until the first device substrate 100 in active region A (correspondence is arranged on alternatively non-transparent district 404) and the gap between the second device substrate 200 are filled up by optical liquid rubber material 300 completely, to guarantee in follow-up processing procedure, first device substrate 100 and the second device substrate 200 can be fitted completely in the A of active region, bubble or gap can not be produced, the quality of impact display.
The coating of above-mentioned optical liquid rubber material and the diffusion process of optical liquid rubber material are such as shown in Fig. 4 A to Fig. 4 D.In Figure 4 A, optical liquid rubber material 300 coats in the A of active region.In order to make optical liquid rubber material 300 have uniform flooding mechanism or dispersal behavior, the coating shape/pattern suggestion of optical liquid rubber material 300 as shown in Figure 4 A.In the present embodiment, owing to being coated with the optical liquid rubber material 300 of a point-like respectively in four corners of active region A, therefore in follow-up optical liquid rubber material diffusion process, can spreading by one way or another equably, and four of active region A corners are filled up.So, the present invention does not limit the coating shape/pattern of optical liquid rubber material 300.In other embodiments, according to the size of electronic installation, the kind of optical liquid rubber material or composition, the coating shape/pattern of optical liquid rubber material 300 can be other kind of shape/pattern.
Afterwards, when carrying out the diffusion process of optical liquid rubber material (as shown in Figure 1B), the dispersal behavior of optical liquid rubber material 300 can as shown in Fig. 4 B and Fig. 4 C.In other words, optical liquid rubber material 300 is spread from active region A toward surrounding zone P gradually.And when optical liquid rubber material 300 diffuses to surrounding zone P, the light having the first irradiation program because of surrounding zone P passes through, therefore namely optical liquid rubber material 300 stops flowing gradually, and forms result as shown in Figure 4 D.In other words, in fig. 4d, what optical liquid rubber material 300 can be complete fills up active region A, and partly diffuses in the P of surrounding zone.
Figure 1B please be return, flow expansion is stopped because correspondence is arranged on the optical liquid rubber material 300 first differential hardening of meeting in the photic zone 402 of photomask 400, thus correspond to optical liquid rubber material 300 in alternatively non-transparent district 404 and be subject to corresponding to the stop of the optical liquid rubber material 300 hardened in photic zone 402, would not overflow to outside the gap between the first device substrate 100 and the second device substrate 200, and can along the edge of the optical liquid rubber material 300 hardened, diffuse in alternatively non-transparent district 404 that other not yet has the position of optical liquid rubber material 300, and then make can to fill part in whole alternatively non-transparent district 404 or active region A and fill up optical liquid rubber material 300, local can not be produced and overflow photic zone 402 or surrounding zone P, and there is no the problem of optical liquid rubber material 300 on the contrary in the alternatively non-transparent district 404 of local or active region A.
Then, as shown in Figure 1 C, first remove photomask 400, carry out the second irradiation program 700 afterwards, harden completely to make optical liquid rubber material 300.According to an embodiment, the wavelength of light that the second irradiation program 700 uses is 300 ~ 400nm, and illumination intensity is 100 ~ 150mW/cm
2, the irradiation time was 57.6 ~ 86.4 seconds.In other words, do not use photomask completely when carrying out the second irradiation program 700, therefore the second irradiation program 700 is that comprehensive illumination optical liquid glue material 300 hardens completely to make optical liquid rubber material 300.That is, originally corresponded to alternatively non-transparent district 404 or the effect of the second irradiation program 700 can be subject to corresponding to the optical liquid rubber material 300 of active region A and harden, and original optical liquid rubber material 300 corresponding to photic zone 402 or correspond to surrounding zone P except hardening except the effect that can be subject to the first irradiation program 500, still can be subject to the impact of the second irradiation program 700 and make the sclerous reaction rate of optical liquid rubber material 300 can continue to improve.Thus, the first device substrate 100 and the second device substrate 200 just can be adhered together, and form the electronic installation as shown in Fig. 1 D and Fig. 4 D.
Therefore, the electronic installation formed according to said method is as shown in Fig. 1 D and Fig. 4 D, it has active region A and the surrounding zone P around active region A, and this electronic installation comprises the first device substrate 100, second device substrate 200 and the optical liquid rubber material 300 after hardening.First device substrate 100 and the second device substrate 200 are toward each other to setting.Optical liquid rubber material 300 after sclerosis is arranged between the first device substrate 100 and the second device substrate 200, and fills up whole active region A and partly diffuse to surrounding zone P.
Similarly, because twice irradiation program of the first irradiation program 600 and the second irradiation program 700 gone through by the optical liquid rubber material 300 diffusing to surrounding zone P in above-mentioned manufacturing process, the firm time therefore diffusing to the optical liquid rubber material 300 of surrounding zone P is longer.In addition, the optical liquid rubber material 300 filling up whole active region A is because only going through an irradiation program of the second irradiation program 700 in above-mentioned manufacturing process, and the firm time therefore filling up the optical liquid rubber material 300 of whole active region A is shorter.In other words, in the electronic installation of Fig. 1 D, sclerous reaction rate (curing rate) R1 filling up the optical liquid rubber material 300 after the sclerosis in whole active region A is less than the sclerous reaction rate R2 of the optical liquid rubber material 300 after the sclerosis that part diffuses in the P of surrounding zone.Wherein, the sclerous reaction rate of the optical liquid rubber material 300 after sclerosis is by high-effect liquid chromatograph (High-Performance Liquid Chromatography, or fourier infrared linear light spectrometer (FTIR HPLC), Fourier Transform Infrared) to measure and obtain, its unit is m/min or mm/sec.In the present embodiment, the scope of sclerous reaction rate R1 can be the scope of 90 ~ 100%, sclerous reaction rate R2 also can be 90 ~ 100%.
In sum, the present invention in time carrying out optical liquid rubber material diffusion process, differential hardening when more simultaneously using photomask to carry out the first irradiation program to make optical liquid rubber material diffuse to surrounding zone.Stop flowing because optical liquid rubber material is subject to will hardening gradually after light irradiates, therefore method of the present invention can avoid the problem that the glue material existing for traditional laminating program overflows.
In addition, differential hardening when the present invention uses photomask to carry out the first irradiation program to make optical liquid rubber material diffuse to surrounding zone, the optical liquid rubber material being arranged in active region then can continue to surrounding flowing and diffusion until optical liquid rubber material fills up active region completely.Therefore, by this photomask and the first irradiation program, except can preventing glue material overflow problem, the use amount of optical liquid rubber material can also be controlled.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claims in the present invention.
