Description

具有多層印刷層的裝置Device with multiple layers of printed layers

本新型是有關一種具有印刷層的裝置,更特定來說,關于一種具有多層印刷層的裝置。The present invention relates to a device having a printed layer, and more particularly to a device having a plurality of printed layers.

隨著近年來智能型手機與平板電腦的熱潮,觸控面板在這類手持式電子裝置的應用上供不應求,促使業界不斷地在研發幷改良其相關的工藝技術,以期能降低生產成本幷提供更高的產能。With the boom of smart phones and tablets in recent years, touch panels are in short supply in the application of such handheld electronic devices, prompting the industry to continuously improve their related process technologies in order to reduce production costs and provide more High production capacity.

一般來說,觸控面板會需要加上一層經過强化處理的保護玻璃(cover glass/lens)來保護其下層的觸控感應器不受刮傷、指紋及污損等影響。此外,由于保護玻璃特別要用在手持式電子裝置上的觸控與顯示方面,故其亦須兼具輕薄、抗壓、耐摔、高透光度等特性。In general, the touch panel needs to be covered with a layer of reinforced glass (cover glass/lens) to protect the underlying touch sensor from scratches, fingerprints, and stains. In addition, since the protective glass is particularly used for touch and display on handheld electronic devices, it must also have the characteristics of lightness, pressure resistance, drop resistance, and high transparency.

傳統上,手持式電子裝置中的各構件(包含顯示面板、觸控面板、及保護玻璃等)會通過一邊框來組裝。然而,由于現今消費者手持式電子裝置(特別是智能型手機)輕薄短小的强烈需求,目前業界已大量地采用無邊框式的外型設計,以期能通過省去邊框構件的方式進一步縮减電子裝置整體的重量與尺寸。Traditionally, components in a handheld electronic device (including display panels, touch panels, and protective glass, etc.) are assembled through a bezel. However, due to the strong demand for lightweight and short-handed consumer electronic devices (especially smart phones), the industry has adopted a large number of frameless exterior designs, in order to further reduce the electronics by eliminating the frame members. The weight and size of the unit as a whole.

在上述無邊框式之設計下,保護玻璃與下層觸控面板的貼合是一門關鍵技術,兩者間貼合的好壞與否即會影響到最終成品的良率。特別是在無邊框式的外型設計中,如圖1所示,其為一時下智能型手機外觀的俯視圖,設計者通常會為了整體外型與色彩配置等設計上的需求而需要在電子裝置的外觀上營造出邊框的感覺,在此例中,其作法為使用印刷油墨先在保護玻璃100上印製一層預定的邊框圖形110,其後再將整片保護玻璃100以印有邊框圖形的那一面來與觸控面板(未示出)進行全面性的貼合。如此,保護玻璃100上未印有邊框圖形的透明區域即作為觸控區域 101,而邊框圖形110則使得成品整體能達成設計者所要呈現給使用者的設計感。Under the above-mentioned frameless design, the bonding of the protective glass and the lower touch panel is a key technology, and whether the fit between the two will affect the yield of the final product. Especially in the frameless exterior design, as shown in FIG. 1 , which is a top view of the appearance of the smart phone for a moment, the designer usually needs the electronic device for the design requirements of the overall appearance and color configuration. The appearance of the frame creates a feeling of a border. In this example, a predetermined layer pattern 110 is printed on the protective glass 100 by using the printing ink, and then the entire protective glass 100 is printed with a border pattern. That side is fully integrated with the touch panel (not shown). Thus, the transparent area on the protective glass 100 that is not printed with the border pattern is used as the touch area. 101, and the border graphic 110 enables the finished product to achieve the design sense that the designer wants to present to the user.

現在請參照圖2,其為傳統技術中一液晶顯示裝置的部分截面示意圖,圖中表示出一印有印刷層210的面板200貼合在一板材220(如上偏光片)上的狀態。如圖所示,面板201上已預先印有印刷層210(如印刷油墨)作為邊框圖形,其幷會通過一粘著層230來與板材220貼合。在此例中,由于面板200與板材220之間隔有印刷層210,故貼合時會因為各印刷層210間不同的高底差而不易掌握其貼合工藝的良率。而為了設計變化或是為了要使邊框圖形的色彩O.D值(光學密度)達到設計者要求的緣故,基材上往往需要層迭地印上數層的印刷層,如圖2例中面板200上即以面積由大到小的順序層迭印上了四層不同的印刷層210。在實作中,邊框圖形所使用的印刷層越多,會使得層間的高低差愈為明顯,愈不利于後續精准貼合工藝的施作。再者,以上述層迭印刷方式印製的印刷層與面板的貼合期間,會容易因為積墨問題而在各印刷層的交界處產生明顯的凸點,進一步放大印刷層結構平均的高低差幷損壞預定的邊框圖形。Referring now to Figure 2, there is shown a partial cross-sectional view of a liquid crystal display device of the prior art, showing a state in which a panel 200 printed with a printed layer 210 is attached to a sheet 220 (such as a polarizer). As shown in the figure, the printing layer 210 (such as printing ink) is pre-printed on the panel 201 as a frame pattern, and the enamel is adhered to the plate 220 through an adhesive layer 230. In this example, since the printing layer 210 is interposed between the panel 200 and the plate 220, the bonding process may be difficult to grasp the yield of the bonding process due to the difference in height between the printing layers 210. In order to design changes or to make the color OD value (optical density) of the border pattern reach the designer's requirements, it is often necessary to layer-print a plurality of printed layers on the substrate, as shown in the panel 200 in FIG. That is, four different printed layers 210 are superimposed on the order of the areas from large to small. In practice, the more printed layers used in the border pattern, the more the difference between the layers will be more obvious, which is not conducive to the subsequent precise bonding process. Moreover, during the bonding of the printed layer printed on the layered printing method and the panel, it is easy to produce obvious bumps at the boundary of each printed layer due to the problem of ink accumulation, and further enlarge the average height difference of the printed layer structure.幷 Damage to the predetermined border graphic.

故此,為了增進觸控面板後段保護玻璃的貼合良率,現今業界亟需開發新的印刷技術與貼合工藝,來解決上述公知技術中存在的缺失。Therefore, in order to improve the bonding yield of the protective glass at the rear of the touch panel, there is an urgent need in the industry to develop new printing technologies and bonding processes to solve the defects in the above-mentioned known technologies.

有鑒于上述公知技術中的缺失,本新型的目的之一即在于提供了一種具有多層印刷層的裝置,該多層印刷層以面積由小而大的順序依序層迭印製在保護基材的貼合面上,其可製作出印刷層高低差較小的保護基材,以提高後續貼合工藝的良率及改善邊框圖形的色彩O.D值。In view of the above-mentioned deficiencies in the prior art, one of the objects of the present invention is to provide a device having a plurality of printed layers which are sequentially laminated on a protective substrate in a small and large area. On the bonding surface, a protective substrate having a small difference in height of the printed layer can be produced to improve the yield of the subsequent bonding process and improve the color OD value of the border pattern.

根據本新型一實施例,其揭露了一種具有多層印刷層的裝置,其包括一保護基材,其具有一向外裸露的開放面及一要與另 一板材貼合的貼合面;以及至少一印刷層,其依序層迭印製在所述保護基材的部分的貼合面上,其中越接近所述貼合面的所述印刷層具有越小的印刷面積。According to an embodiment of the present invention, a device having a plurality of printed layers is disclosed, comprising a protective substrate having an open exposed surface and an additional a sheet-fitting abutting surface; and at least one printed layer sequentially printed on the bonding surface of the portion of the protective substrate, wherein the printing layer closer to the bonding surface has The smaller the printed area.

透過印刷層依面積由小而大的印刷設計,可有效降低所述印刷層間的層間高低差,有利于後續與板材的貼合。Through the small and large printing design of the printing layer, the interlayer height difference between the printing layers can be effectively reduced, which is favorable for subsequent bonding with the board.

無疑地,本新型的這類目的與其它目的在讀過下文以多種圖示與繪圖來描述的較佳實施例細節說明後將變得更為顯見。The objectives and other objects of the present invention will become more apparent from the detailed description of the preferred embodiments illustrated herein.

請參照圖3,其為根據本新型實施例一具有多層印刷層裝置的截面示意圖,圖中描繪出保護基材300貼合在一板材320(如顯示面板中的上偏光片)上的狀態。在本實施例中,保護基材300供來作為保護所述下層板材320(如一具有一觸控感應層的觸控基板或為一顯示面板的上偏光片)的保護層,其材質可為透明的玻璃(如一保護玻璃)或塑料。如圖所示,保護基材300上會分為一邊框區300a與一被該邊框區圍繞的非邊框區300b,所述邊框區300a為一圖形區域,其上可印有不透明的油墨圖形以定義出裝置的邊框或是賦予裝置色彩設計上的變化。非邊框區300b即為整個基材的觸控區域,其上未有印製任何圖形,以讓影像信息得以呈現給使用者。保護基材300會具有一向外裸露的開放面302及一要與板材320貼合的貼合面303。所述開放面302于保護基材300貼合及組裝後會裸露在裝置的外部,而貼合面303上層迭設置有數層的印刷層310,所述數層的印刷層310可為油墨層,其依面積由小到大的方式依序以層迭印刷的方式印在所述保護基材300貼合面303的邊框區300a上。開放面302的非邊框區300b為觸控區域,其可供使用者以手指或觸控筆在其上進行劃綫或點選的動作以達成操控效果。在貼合的過程中,保護基材300會通過一粘著層330來與下層的板材320進行全面性的貼合。在一實施例中,保護基材300還包括一觸控感應層,該觸控感應層形成于所述保護基材300貼合面303的非邊框區300b(即觸控區域)上,藉此形成一在 保護基材上集成觸控功能的觸控面板,在貼合過程中,通過一粘著層330與下層的板材320(如顯示面板中的上偏光片)進行貼合。Please refer to FIG. 3, which is a schematic cross-sectional view of a device having a multi-layer printing layer according to an embodiment of the present invention, illustrating a state in which the protective substrate 300 is attached to a sheet 320 (such as an upper polarizer in a display panel). In this embodiment, the protective substrate 300 is provided as a protective layer for protecting the lower layer plate 320 (such as a touch substrate having a touch sensing layer or an upper polarizing plate for a display panel), and the material thereof may be transparent. Glass (such as a protective glass) or plastic. As shown in the figure, the protective substrate 300 is divided into a frame area 300a and a non-frame area 300b surrounded by the frame area. The frame area 300a is a graphic area on which an opaque ink pattern can be printed. Define the border of the device or give a change in the color design of the device. The non-frame area 300b is the touch area of the entire substrate, and no graphic is printed thereon to allow image information to be presented to the user. The protective substrate 300 will have an outwardly exposed open face 302 and a conforming face 303 to be bonded to the sheet 320. The open surface 302 is exposed to the outside of the device after the protective substrate 300 is attached and assembled, and the bonding surface 303 is laminated with a plurality of printed layers 310, and the printed layers 310 of the plurality of layers may be ink layers. It is printed on the frame region 300a of the bonding surface 303 of the protective substrate 300 in a layered manner in a small to large manner in a small to large manner. The non-frame area 300b of the open surface 302 is a touch area, which can be used by a user to perform a scribing or clicking action on a finger or a stylus to achieve a manipulation effect. During the bonding process, the protective substrate 300 will be fully bonded to the underlying sheet 320 through an adhesive layer 330. In one embodiment, the protective substrate 300 further includes a touch sensing layer formed on the non-frame region 300b (ie, the touch region) of the bonding surface 303 of the protective substrate 300. Form one in The touch panel integrated with the touch function on the protective substrate is bonded to the lower layer of the sheet 320 (such as the upper polarizer in the display panel) through an adhesive layer 330 during the bonding process.

現在請參照圖4,其描繪出根據本新型實施例數層的印刷層在保護基材實際與板材完成貼合後所呈現的部分俯視圖。從圖中可以看出,層迭的印刷層410從基材開放面的視角來看會呈現邊框狀態,其中,印刷層410迭層較多的區域(如區域410b,其包含兩個迭層)會較迭層較少的區域(如區域410a,僅一個迭層)呈現較深、較密實的色澤,代表其O.D值(光學密度)較高,而越往印刷層迭層較多的邊緣區域色澤就越深,未印有任何印刷層的中間透明區域則作為觸控區域401。須注意,在其它新型狀態中,印刷層也可能呈現不同于本實施例般內深外淺的色層分布狀態,例如其可能呈外淺內深或不規則分的色層分布狀態,端視設計者的設計而定。通過上述控制印刷層的層迭設置與分布,設計者可在基材面上設計出富色彩與外型變化的邊框狀態。Referring now to Figure 4, a partial plan view of a printed layer of a plurality of layers in accordance with an embodiment of the present invention after the protective substrate has actually been bonded to the sheet material is depicted. As can be seen from the figure, the laminated printed layer 410 will assume a state of the bezel from the perspective of the open face of the substrate, wherein the printed layer 410 has a plurality of layers (such as the region 410b, which includes two layers). A region with less overlap (such as region 410a, only one laminate) exhibits a darker, denser color, representing a higher OD value (optical density), and an edge region with more layers of printed layers. The darker the color, the intermediate transparent area without any printed layer is used as the touch area 401. It should be noted that in other new states, the printed layer may also exhibit a color distribution state that is different from the depth and the outer layer of the present embodiment, for example, it may be in the form of an outer shallow inner depth or an irregular color distribution layer. Depending on the designer's design. By controlling the lamination setting and distribution of the printed layer as described above, the designer can design a frame state rich in color and appearance on the substrate surface.

本新型的特徵在于,保護基材上所設置的數層印刷層以面積由小而大的順序依序層迭印製在基材的貼合面上,其與公知技術中依面積由大而小的順序層迭印製的傳統作法相反。就本新型而言,複參照圖3,在印刷期間先行印製面積較小的印刷層(如310a)的作法可使後續印製的印刷層(如310b)以該前一層印刷層作為支撑結構基礎來印製,使得該後續印製、面積較大的印刷層能順著該前層印刷層的表面分布,如此將使整體的印刷層坡度趨于平緩,不會有先前技術作法中如圖2所示突兀的高低差結構分布或是易產生凸點的情形發生。The present invention is characterized in that the plurality of printed layers provided on the protective substrate are sequentially layer-printed on the bonding surface of the substrate in a small and large order, which is large in size according to the prior art. The traditional practice of small sequential layer printing is the opposite. For the purposes of the present invention, referring to Figure 3, the printing of a relatively small printed layer (e.g., 310a) prior to printing allows the subsequent printed layer (e.g., 310b) to have the previous printed layer as a support structure. The basis is printed so that the subsequent printed, larger printed layer can be distributed along the surface of the front printed layer, which will make the overall printed layer slope gentle, without the prior art practice The distribution of the height difference structure shown in Fig. 2 or the occurrence of bumps easily occurs.

現在請參照圖5與圖6,其分別為根據先前技術中以面積由大而小的層迭印刷方式以及本新型技術中以面積由小而大的層迭印刷方式所印製出的印刷層層間高低差分布的示意圖。從圖5與圖6的比較可以看出,以先前技術的層迭印刷方式所得出的印刷層結構會具有較大的層間高低差h1(如2.98 μm),相較之下,本新型作法所得出的印刷層結構平均而言會具有相對較小的高低差h2(如0.79 μm)。再者,以先前技術方式所印出的迭層結構其層 跟層之間的波度較陡峭,以本新型方法印出的迭層結構其層跟層之間的波度較為平緩。此兩圖比較可證明以本新型印製方法所得出帶有印刷層圖形的保護基材在後續的貼合工藝中會有較好的良率表現。Referring now to FIG. 5 and FIG. 6 , respectively, the printing layers are printed according to the prior art in a layered printing method in which the area is large and small, and in the prior art, the printing is performed in a small and large area. Schematic diagram of the distribution of height difference between layers. It can be seen from the comparison between FIG. 5 and FIG. 6 that the printed layer structure obtained by the prior art layer printing method has a large interlayer height difference h1 (for example, 2.98 μm), which is obtained by the novel method. The resulting printed layer structure will, on average, have a relatively small height difference h2 (e.g., 0.79 μm). Furthermore, the layered structure printed in the prior art is layered The waviness between the layers is steeper, and the layered structure printed by the novel method has a smoother waviness between layers. Comparison of the two figures demonstrates that the protective substrate with the printed layer pattern obtained by the novel printing method has a better yield performance in the subsequent bonding process.

現在請參照圖7,其為根據本新型實施例一多層印刷層的印刷方法流程700。首先在步驟區塊701中,一保護基材被提供來作為下層板材的保護件,該保護基材具有一要向外裸露的開放面及一要與另一板材貼合的貼合面,其材質可為透明的玻璃或塑料,具有輕薄、抗壓、耐摔、高透光度等特性。接著,在步驟區塊702中,在所述保護基材的部分的貼合面上依序層迭印上面積由小至大的至少一印刷層。所述印刷層作為一邊框圖形,以與保護基材的透明觸控區域區別。Reference is now made to Fig. 7, which is a flow 700 of a method of printing a multilayer printed layer in accordance with an embodiment of the present invention. First, in step block 701, a protective substrate is provided as a protective member for the underlying sheet material, the protective substrate having an open side to be exposed outward and a bonding surface to be bonded to the other sheet. The material can be transparent glass or plastic, and has the characteristics of lightness, pressure resistance, drop resistance and high transparency. Next, in step block 702, at least one printed layer having a small to large area is sequentially layered on the bonding surface of the portion of the protective substrate. The printed layer acts as a border pattern to distinguish it from the transparent touch area of the protective substrate.

在本新型進一步的實施例中,如步驟區塊703所示,會在印上所述印刷層後將帶有所述多層印刷層的保護基材進一步與另一板材作全面性的貼合。該貼合步驟可能通過在所述板材上塗覆一層粘合劑後將其與保護基材彼此壓合的方式來進行。壓合後所述層迭的多層印刷層從基材開放面的視角來看會呈現邊框狀態。In a further embodiment of the present invention, as indicated by step block 703, the protective substrate with the multilayer printed layer is further conformed to the other sheet after the printed layer is printed. This laminating step may be carried out by applying a layer of adhesive to the sheet and pressing it together with the protective substrate. After lamination, the laminated multilayer printed layer exhibits a bezel state from the perspective of the open face of the substrate.

以上所述僅為本新型的優選實施例而已,幷不用于限制本新型,對于本領域的技術人員來說,本新型可以有各種更改和變化。凡在本新型的精神和原則之內,所作的任何修改、等同替換、改進等,均應包含在本新型的保護範圍之內。The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made by those skilled in the art.
