Description
本發明係關於行動電話、數位相機、電視、電腦、及其他電子機器的面板基板上施以加飾而構成的影像顯示面板及其製造方法。The present invention relates to an image display panel constructed by attaching a panel substrate of a mobile phone, a digital camera, a television, a computer, and other electronic devices, and a method of manufacturing the same.
對設於從前的電子機器等的影像顯示面板之面板基板施以加飾,於其上貼附光學雙面膠帶的場合,在加飾所產生的階差的內側會產生空氣層。亦即,如圖6(a)所示,在形成影像顯示的可透視的面板基板21的背面21a施以加飾,於構成此加飾的層(以下稱為「加飾層」)22的上面22a及面板基板21的背面21a貼附光學雙面膠帶23的場合,如圖6(b)所示,面板基板21與加飾層22之階差24的角落部等會產生如空氣囤積那樣的空氣層25。When a panel substrate of an image display panel such as an electronic device is attached, and an optical double-sided tape is attached thereto, an air layer is generated inside the step caused by the decoration. That is, as shown in FIG. 6(a), the back surface 21a of the see-through panel substrate 21 on which the image display is formed is decorated to form a layer (hereinafter referred to as "decorative layer") 22 constituting the decoration. When the optical double-sided tape 23 is attached to the upper surface 22a and the back surface 21a of the panel substrate 21, as shown in FIG. 6(b), the corner portion of the step difference 24 between the panel substrate 21 and the decorative layer 22 may be condensed like air. Air layer 25.
在此,為了消除如前所述產生於面板基板21與加飾層22之階差24的空氣層25,而在下述步驟,雖可使用加壓脫泡裝置進行抽除空氣層22的空氣之作業,但加壓脫泡後,會由於光學雙面膠帶23的復原性而有隨著時間的經過而再度發生空氣層25之虞。進而,也有要平滑地貼附光學雙面膠帶23有其困難之問題。Here, in order to eliminate the air layer 25 which is generated in the step difference 24 between the panel substrate 21 and the decorative layer 22 as described above, in the following step, the air of the air layer 22 may be removed by using a pressurized defoaming device. After the work, but after the pressure defoaming, the air layer 25 is again generated due to the recovery of the optical double-sided tape 23 over time. Further, there is a problem that it is difficult to attach the optical double-sided tape 23 smoothly.
此外,如圖6(a)所示,藉由使加飾層22例如以2層之油墨層22c、22d重疊的構成而在加飾層22設階差22b的話,階差24的寬幅會變大。在此狀況於面板基板21與加飾層22的背面貼附光學雙面膠帶23的場合,如圖6(b)所示,光學雙面膠帶23不會變得平滑而會在階差24的附近產生如摺痕29那樣的變形。接著,於此光學雙面膠帶23的背面貼附其他構件27的話,構件27為堅硬質地不變形,而在根據PET樹脂等使面板基板21往構件27側強制拉伸而變形的狀態下附著,使面板基板21的內部往背面側變形為彎曲形狀31。此外,此時,如圖7所示,由前方來看影像顯示面板20時,沿著前述階差24的內側產生的光學雙面膠帶23的摺痕29,會有在加飾層22的沿著內側附近看到筋狀痕的問題。Further, as shown in FIG. 6(a), when the decorative layer 22 is formed by, for example, a two-layer ink layer 22c, 22d, a step difference 22b is provided in the decorative layer 22, the width of the step 24 is wide. Become bigger. In this case, when the optical double-sided tape 23 is attached to the back surface of the panel substrate 21 and the decorative layer 22, as shown in FIG. 6(b), the optical double-sided tape 23 does not become smooth and may be in the step 24 A deformation such as the crease 29 is generated in the vicinity. Then, when the other member 27 is attached to the back surface of the optical double-sided tape 23, the member 27 is adhered in a state of being deformed by forced stretching of the panel substrate 21 toward the member 27 side by a PET resin or the like. The inside of the panel substrate 21 is deformed into a curved shape 31 toward the back side. Further, at this time, as shown in FIG. 7, when the image display panel 20 is viewed from the front, the crease 29 of the optical double-sided tape 23 generated along the inner side of the aforementioned step 24 may be along the edge of the decorative layer 22. The problem of seeing ribs near the inside is seen.
進而,如圖6(a)所示於加飾層22形成抽氣孔26等的場合,如圖6(b)所示於面板基板21與加飾層22的背面貼合光學雙面膠帶23,如圖6(c)所示於光學雙面膠帶23的背面在按壓狀態貼附其他構件27的話,如圖6(d)所示面板基板21在往構件27側強制拉伸的狀態附著。因此,抽氣孔26的處所之面板基板21變成往背面側扭曲為凹狀的形狀。Further, when the evacuation holes 26 and the like are formed in the decorative layer 22 as shown in FIG. 6(a), the optical double-sided tape 23 is bonded to the back surface of the panel substrate 21 and the decorative layer 22 as shown in FIG. 6(b). When the other member 27 is attached to the back surface of the optical double-sided tape 23 as shown in FIG. 6(c), the panel substrate 21 is attached to the member 27 side as shown in FIG. 6(d). Therefore, the panel substrate 21 at the position of the air vent 26 is twisted into a concave shape toward the back side.
進而,另外如圖7所示,於面板基板21的背面施以商標標記等加飾部28的場合,其剖面形狀成為如圖8(a)所示。此圖,係於面板基板21與加飾部28的背面貼附光學雙面膠帶23者,光學雙面膠帶23沿著加飾部28的厚度方向形成為波浪狀。接著,如圖8(b)、(c)所示,於光學雙面膠帶23的背面貼合玻璃板等其他硬質的構件27的場合,各加飾部28、28之間的光學雙面膠帶23被往構件27側拉伸而變形,由PET樹脂等構成的面板基板21於各個加飾部28產生往前面側凸起狀的變形21b。又,此凸起狀的變形21b,如圖7所示,於各加飾部28例如成為輪狀的扭曲30而產生粗糙惡劣的變形。Further, as shown in Fig. 7, when the decorative portion 28 such as a trademark mark is applied to the back surface of the panel substrate 21, the cross-sectional shape thereof is as shown in Fig. 8(a). In the figure, the optical double-sided tape 23 is attached to the back surface of the panel substrate 21 and the decorative portion 28, and the optical double-sided tape 23 is formed in a wave shape along the thickness direction of the decorative portion 28. Next, as shown in FIGS. 8(b) and 8(c), when another rigid member 27 such as a glass plate is bonded to the back surface of the optical double-sided tape 23, the optical double-sided tape between the decorative portions 28 and 28 is provided. The panel substrate 21 which is stretched and deformed toward the member 27 side, and the panel substrate 21 made of a PET resin or the like has a convex deformation 21b which is convex toward the front side in each of the decorative portions 28. Further, as shown in FIG. 7, the convex deformation 21b is, for example, a wheel-shaped twist 30 in each of the decorative portions 28, and is rough and deformed.
然而,於下列專利文獻1,揭示著於從前的影像顯示裝置,以不使充填於透明面板與影像顯示部側面板之間的硬化樹脂產生氣泡的方式製造之影像顯示裝置及其製造方法。However, in the following Patent Document 1, an image display device manufactured by a conventional image display device that does not cause bubbles to be formed between the transparent resin and the image display portion side panel is disclosed, and a method of manufacturing the same.
然而,此影像顯示裝置及其製造方法,係於設在透明面板之周圍部的間隔件彼此之間設置缺口部者。此外,藉由影像顯示部側面板的按壓而以沒有氣泡的狀態使透明面板的上面且充填於間隔件的內方側的硬化樹脂成為平滑,同時使剩餘的硬化樹脂由缺口部排出。However, the image display device and the method of manufacturing the same are those in which a notch is provided between spacers provided around the transparent panel. In addition, the hardened resin filled on the upper surface of the transparent plate and filled on the inner side of the spacer is smoothed by the pressing of the image display unit side panel, and the remaining hardened resin is discharged from the notch.
亦即,於專利文獻1之影像顯示裝置及其製造方法,於各間隔件上面不施以硬化樹脂,此外剩餘的硬化樹脂由間隔件與間隔件之間的缺口部排出,所以不能連續地形成設於透明面板的周圍部的間隔件,而成為於各缺口部中斷的形狀。In the image display device of Patent Document 1, and the method of manufacturing the same, the cured resin is not applied to the spacers, and the remaining hardened resin is discharged from the gap between the spacer and the spacer, so that the resin cannot be continuously formed. The spacer provided in the peripheral portion of the transparent panel has a shape in which each of the cutout portions is interrupted.

Further, the penetration hole 9 of the decorative layer 3 is also filled in a state in which the cured resin 4 has the uniform back surface 4a.
此外,圖4(b)所示的步驟,在本實施例,作為硬化樹脂4的充填方法,採用將紫外線硬化樹脂或熱硬化樹脂等之硬化樹脂4藉由根據絲網印刷等之全面固體印刷而進行充填的方法。於這樣的充填方法,硬化樹脂4的黏性,必須是以在加飾層3導致之階差3b的內方側或角落部不產生氣泡或空氣層的方式,可充分地遶入階差3b或穿透孔9之內部的角落部之黏性。Further, in the present embodiment, as the method of filling the cured resin 4, the hardened resin 4 such as an ultraviolet curable resin or a thermosetting resin is printed by a solid solid according to screen printing or the like. And the method of filling. In such a filling method, the viscosity of the cured resin 4 must be such that no air bubbles or air layers are generated on the inner side or the corner portion of the step 3b caused by the decorative layer 3, and the step 3b can be sufficiently wound. Or penetrating the corners of the inner portion of the hole 9.
又,圖4(b)所示的硬化樹脂4的充填方法,相當於圖3(b)之方法,如此般藉由根據絲網印刷等之全面固體印刷而充填硬化樹脂4的方法,適於在1枚薄板狀之面板基板2上形成複數之影像顯示面板1而構成大尺寸板5的場合,適用於影像顯示面板1的量產。Moreover, the method of filling the cured resin 4 shown in FIG. 4(b) corresponds to the method of FIG. 3(b), and is preferably filled by the method of filling the cured resin 4 by integral solid printing such as screen printing. When a plurality of image display panels 1 are formed on one thin plate-shaped panel substrate 2 to form a large-sized board 5, the image display panel 1 is suitable for mass production.
又,作為硬化樹脂4使用的紫外線硬化樹脂,於本發明沒有特別限定,在泛用性、價格等方面,以氨基丙烯酸酯系紫外線硬化樹脂為較佳。此氨基丙烯酸酯系紫外線硬化樹脂,例如有聚酯氨酯(甲基)丙烯酸酯,聚醚(甲基)丙烯酸酯,聚氨酯(甲基)丙烯酸碳酸酯等。Further, the ultraviolet curable resin used as the curable resin 4 is not particularly limited in the present invention, and an amino acrylate-based ultraviolet curable resin is preferable in terms of general availability and price. Examples of the amino acrylate-based ultraviolet curable resin include polyester urethane (meth) acrylate, polyether (meth) acrylate, and urethane (meth) acrylate carbonate.
此外,作為硬化樹脂4使用的熱硬化樹脂,於本發明沒有特別限定,適合使用矽系熱硬化樹脂、尿烷系熱硬化樹脂、聚酯系熱硬化樹脂、聚醯亞胺等。In addition, the thermosetting resin used as the curing resin 4 is not particularly limited, and a lanthanum thermosetting resin, a urethane thermosetting resin, a polyester thermosetting resin, a polyimine or the like is suitably used.
其次,如圖4(c)所示,於前述之硬化樹脂4的上面在覆蓋了塗布根據氟或矽等之脫模劑7之分隔膜6的狀態將該分隔膜6往硬化樹脂4側加壓,同時藉由UV照射裝置10進行UV照射。Next, as shown in FIG. 4(c), the separator film 6 is applied to the hardened resin 4 side in a state in which the separator 6 of the release agent 7 according to fluorine or ruthenium is coated on the upper surface of the above-mentioned cured resin 4. At the same time, UV irradiation is performed by the UV irradiation device 10.
將這樣的加壓及UV照射適用於大尺寸板5的製造的場合,如圖3(c)所示,使成為於前述硬化樹脂4的上面中介著脫模劑7而覆蓋分隔膜6的狀態。When such a pressurization and UV irradiation are applied to the production of the large-sized sheet 5, as shown in FIG. 3(c), the release agent 7 is placed on the upper surface of the cured resin 4 to cover the separator 6. .
作為其具體的方法,如圖3(e)所示,在對施於面板基板2的加飾層3的階差3b的內側及上面充填硬化樹脂4的狀態通過上下之輥11a、11b間,同時藉由在硬化樹脂4的背面側捲入分隔膜6,而以分隔膜6按壓硬化樹脂4的背面。同時,藉由從設於上下之輥11a、11b的出口附近的UV照射裝置10照射UV光線,可以使按壓之後的硬化樹脂4UV硬化。藉由這樣的步驟,使掩埋住設於面板基板2的背面之加飾層3的階差3b的硬化樹脂4的背面4a以均勻的平滑的狀態進行硬化。As a specific method, as shown in FIG. 3(e), the state in which the hardened resin 4 is filled on the inner side and the upper surface of the step 3b of the decorative layer 3 applied to the panel substrate 2 passes between the upper and lower rolls 11a and 11b. At the same time, the separator film 6 is wound on the back side of the cured resin 4, and the back surface of the cured resin 4 is pressed by the separator 6. At the same time, by irradiating the UV light from the UV irradiation device 10 provided near the exit of the upper and lower rolls 11a, 11b, the hardened resin 4 after pressing can be UV-cured. By such a procedure, the back surface 4a of the cured resin 4 which is buried in the step 3b of the decorative layer 3 provided on the back surface of the panel substrate 2 is hardened in a uniform and smooth state.
又,於這樣的步驟,如圖4(d)所示,被加壓的硬化樹脂4往平面方向伸展而由面板基板2及加飾層3的外形往外方側滲出而形成為剩餘部4c。Moreover, in such a step, as shown in FIG. 4(d), the pressed cured resin 4 is stretched in the planar direction and is oozing out from the outer shape of the panel substrate 2 and the decorative layer 3 to form the remaining portion 4c.
接著,如圖3(d)或圖4(e)所示,剝離分隔膜6。此時,於分隔膜6如前所述中介著脫模劑7,所以可容易地由硬化的硬化樹脂4剝離。Next, as shown in FIG. 3(d) or FIG. 4(e), the separator film 6 is peeled off. At this time, since the release film 7 is interposed between the separator film 6 as described above, it can be easily peeled off from the cured hardened resin 4.
進而,如圖4(e)所示,將硬化樹脂4的外形之剩餘部4c裁切為特定形狀,使面板基板2及加飾層3的外形成為同樣的外形。Further, as shown in FIG. 4(e), the remaining portion 4c of the outer shape of the cured resin 4 is cut into a specific shape, and the outer shape of the panel substrate 2 and the decorative layer 3 has the same outer shape.
此外,如圖4(f)所示,做成在被形成於於施作於面板基板2的背面之硬化樹脂4的背面4a的平滑面上貼附光學雙面膠帶9的製品的話,能夠以光學雙面膠帶9的背面之黏接面黏接影像顯示面板1之安裝處所或其他零件。Further, as shown in FIG. 4(f), when the product is attached to the smooth surface of the back surface 4a of the cured resin 4 applied to the back surface of the panel substrate 2, the optical double-sided tape 9 can be attached. The bonding surface of the back surface of the optical double-sided tape 9 is adhered to the mounting place or other parts of the image display panel 1.
作為前述實施例之其他的實施例,本發明之影像處理裝置也可以藉由圖5(a)~(f)所示的步驟來製造。但是,此步驟與前述圖4(a)~(f)不同之點,僅在於圖5(b)所示之步驟,其他步驟的內容為相同。As another embodiment of the foregoing embodiment, the image processing apparatus of the present invention can also be manufactured by the steps shown in Figs. 5(a) to (f). However, this step differs from the above-described FIGS. 4(a) to 4(f) only in the steps shown in FIG. 5(b), and the contents of the other steps are the same.
亦即,圖5(b)所示的步驟,係使硬化樹脂4由上方垂下而充填的方法,藉此可以於面板基板2的加飾層3之階差3b的內側及加飾層3的上面3a連續地充填硬化樹脂4。That is, the step shown in FIG. 5(b) is a method in which the hardened resin 4 is suspended from above and can be filled on the inner side of the step 3b of the decorative layer 3 of the panel substrate 2 and the decorative layer 3 The upper 3a is continuously filled with the hardening resin 4.
此外在量產本實施例之影像顯示面板1的場合,藉由使用未圖示之分配器來控制硬化樹脂4的充填量,藉此節省硬化樹脂避免浪費亦可。Further, in the case of mass production of the image display panel 1 of the present embodiment, the amount of the hardened resin 4 to be filled can be controlled by using a dispenser (not shown), thereby saving the hardened resin from waste.
此外,於圖5(c),作為中介著分隔膜6而按壓硬化樹脂4的方法,除了使用前述之輥以外,使用廣為週知的層疊機亦為可能。於此步驟,也如前所述,被加壓的硬化樹脂4往平面方向伸展而由面板基板2及加飾層3的外形往外方側滲出而形成為剩餘部4c。接著,在圖5(e)所示的步驟藉由裁切外形之剩餘部4c,而可得特定形狀之製品。In addition, in FIG. 5(c), as a method of pressing the cured resin 4 with the separator 6 interposed therebetween, it is also possible to use a widely known laminator in addition to the above-described rolls. In this step, as described above, the pressed hardened resin 4 is extended in the planar direction and is oozing out from the outer shape of the outer surface of the panel substrate 2 and the decorative layer 3 to form the remaining portion 4c. Next, in the step shown in Fig. 5(e), a product having a specific shape can be obtained by cutting the remaining portion 4c of the outer shape.
