Description
本發明是有關於一種觸控面板，尤其是有關於一種薄型化的觸控面板。The present invention relates to a touch panel, and more particularly to a thinned touch panel.
傳統以玻璃基材為主的觸控面板多採用兩片玻璃結構，亦即由一片觸控玻璃再加上一片保護玻璃所製成。目前，為迎合行動裝置輕薄設計趨勢，開發出一種單片式(One glass solution,OGS)觸控面板，其中單片式觸控面板係將觸控感測層(touch sensor)與保護玻璃(cover glass)結合，使觸控面板的結構簡化成一片玻璃基板的形式。如此，由於觸控面板具薄型及輕量化的優勢且減去一面玻璃的感測阻抗，可大幅提升觸控面板的透光度及觸控靈敏度。Traditionally, glass substrates are mainly made of two glass structures, which are made of a touch glass and a piece of protective glass. At present, in order to meet the trend of thin design of mobile devices, a one-piece (OGS) touch panel has been developed, in which a single-touch panel is a touch sensor and a cover glass. Glass) combines to simplify the structure of the touch panel into a form of a glass substrate. In this way, since the touch panel has the advantages of thinness and light weight and minus the sensing impedance of one glass, the transmittance and touch sensitivity of the touch panel can be greatly improved.
單片式觸控面板的製程係以黃光製程在玻璃基板上形成一黑色矩陣(black matrix,BM)以遮蔽設置於觸控面板上的導線層。此外，觸控面板的邊框上還可進一步地設置一裝飾膜(decoration film)。藉由在裝飾膜內摻雜其他顏料以形成所需顏色及圖案，而可遮蓋黑色矩陣以及玻璃基板的邊緣，以增加觸控面板整體的外觀的變化及美觀程度。The process of the monolithic touch panel forms a black matrix (BM) on the glass substrate in a yellow light process to shield the wire layer disposed on the touch panel. In addition, a decoration film may be further disposed on the frame of the touch panel. The black matrix and the edge of the glass substrate can be covered by doping other pigments in the decorative film to form a desired color and pattern, thereby increasing the appearance and aesthetics of the entire touch panel.
在生產時，須考量裝飾膜貼附於玻璃基板時的精度，所以在設計上，裝飾膜與玻璃基板或黑色矩陣的邊緣之 間會預留間距，以避免裝飾膜因貼附精度不佳而突出於觸控面板。然而，預留間距卻會導致玻璃基板邊緣或黑色矩陣部分露出於裝飾膜外，造成觸控面板整體外觀不佳的問題。此外，黑色矩陣會形成開口以對應功能鍵或攝像頭，而裝飾膜需亦需對應設置開口。同樣基於裝飾膜貼附精度的問題，為了避免裝飾膜遮蓋黑色矩陣的開口，裝飾膜的開口尺寸通常會設計成大於黑色矩陣的開口，但此也會導致黑色矩陣部分露出於裝飾膜外的問題。In the production, the precision of the decorative film attached to the glass substrate must be considered, so in design, the decorative film and the edge of the glass substrate or the black matrix The spacing is reserved to prevent the decorative film from protruding beyond the touch panel due to poor adhesion accuracy. However, the reserved pitch may cause the edge of the glass substrate or the black matrix portion to be exposed outside the decorative film, resulting in a problem that the overall appearance of the touch panel is not good. In addition, the black matrix will form an opening to correspond to a function key or a camera, and the decorative film also needs to be correspondingly provided with an opening. Also based on the problem of decorative film attachment accuracy, in order to prevent the decorative film from covering the opening of the black matrix, the opening size of the decorative film is usually designed to be larger than the opening of the black matrix, but this also causes the black matrix portion to be exposed outside the decorative film. .
本發明提供了一種觸控面板，以解決先前技術中裝飾膜無法完全覆蓋玻璃基板邊緣或黑色矩陣所造成的問題。The present invention provides a touch panel to solve the problems caused by the prior art that the decorative film cannot completely cover the edge of the glass substrate or the black matrix.

請參照圖1及圖2A，圖1係繪示依照本發明一實施例的一種觸控面板100的上視示意圖，圖2A係沿圖1之剖面線A-A’的剖面示意圖。如圖1及圖2A所示，一種觸控面板100包括透明基板110、第一裝飾層120、遮光層130及第二裝飾層140。透明基板110具有相對的第一表面112a及第二表面112b，且透明基板110具有觸控區114a以及位於觸控區114a旁的周邊區114b。在本實施例中，周邊區114b圍繞觸控區114a，遮光層130、第一裝飾層120及第二裝飾層140設置於於周邊區114b上圍繞觸控區114a，但不以此為限。在其他實施例中，周邊區 也可設置於觸控區的至少一側邊，而遮光層130、第一裝飾層120及第二裝飾層140則對應周邊區114b的位置設置。另外，透明基板110可由玻璃或塑膠等透明材料所構成，但不以此為限。Referring to FIG. 1 and FIG. 2A, FIG. 1 is a schematic top view of a touch panel 100 according to an embodiment of the invention, and FIG. 2A is a cross-sectional view along the line A-A' of FIG. As shown in FIG. 1 and FIG. 2A , a touch panel 100 includes a transparent substrate 110 , a first decorative layer 120 , a light shielding layer 130 , and a second decorative layer 140 . The transparent substrate 110 has an opposite first surface 112a and a second surface 112b, and the transparent substrate 110 has a touch area 114a and a peripheral area 114b located beside the touch area 114a. In this embodiment, the peripheral area 114b surrounds the touch area 114a, and the light shielding layer 130, the first decorative layer 120, and the second decorative layer 140 are disposed on the peripheral area 114b around the touch area 114a, but not limited thereto. In other embodiments, the peripheral zone It can also be disposed on at least one side of the touch area, and the light shielding layer 130, the first decorative layer 120, and the second decorative layer 140 are disposed corresponding to the position of the peripheral area 114b. In addition, the transparent substrate 110 may be made of a transparent material such as glass or plastic, but is not limited thereto.
本實施例的觸控面板100可與顯示裝置(圖未示)相互堆疊，以組成觸控顯示裝置(例如：智慧型手機、平板電腦...等)。透明基板110的觸控區114a內可進一步設置觸控電路單元(圖未示)，藉以感應使用者的觸控動作。也就是說，使用者可在觸控區114a內進行觸控，藉以操作觸控顯示裝置。需說明的是，在本實施例中，周邊區114b為第一裝飾層120、遮光層130及第二裝飾層140所設置的區域，而觸控電路單元也可能設置於周邊區114b。The touch panel 100 of the present embodiment can be stacked on a display device (not shown) to form a touch display device (for example, a smart phone, a tablet, etc.). A touch circuit unit (not shown) may be further disposed in the touch area 114a of the transparent substrate 110 to sense a touch action of the user. That is, the user can perform touch in the touch area 114a to operate the touch display device. It should be noted that, in this embodiment, the peripheral region 114b is an area provided by the first decorative layer 120, the light shielding layer 130, and the second decorative layer 140, and the touch circuit unit may also be disposed in the peripheral region 114b.
遮光層130設置於透明基板110的第二表面112b上，遮光層130具有相對的第二外側面132與第二內側面134，第二內側面134係面向觸控區114a。在本實施例中，遮光層130可為一黑色矩陣(black matrix,BM)，但不以此為限。此黑色矩陣可延伸至觸控區114a內，亦即黑色矩陣可形成於觸控區114a及周邊區114b，其中黑色矩陣之位於周邊區114b的部分即為遮光層130。此外，觸控面板100還可包含一線路層150形成於遮光層130上，以作為觸控面板100傳遞電能或訊號的周邊線路。此線路層150例如是電性連接至觸控區114a內的觸控電路單元，且可在同一製程中同時形成線路層150及觸控區114a內的觸控電路單元。另外，遮光層130的設置，可有效地遮蓋線路層150，以避免線路層150於外觀所視。需說明的是，雖然圖中僅以單層線路來表示線路層150，實際上，線路層150可為多層結構，由於此為所屬技 術領域具有通常知識者所熟知的結構，在此不詳加敘述。The light shielding layer 130 is disposed on the second surface 112b of the transparent substrate 110. The light shielding layer 130 has opposite second outer side surfaces 132 and second inner side surfaces 134, and the second inner side surface 134 faces the touch area 114a. In this embodiment, the light shielding layer 130 may be a black matrix (BM), but is not limited thereto. The black matrix can be extended into the touch area 114a, that is, the black matrix can be formed on the touch area 114a and the peripheral area 114b. The portion of the black matrix located in the peripheral area 114b is the light shielding layer 130. In addition, the touch panel 100 may further include a circuit layer 150 formed on the light shielding layer 130 to serve as a peripheral circuit for transmitting power or signals to the touch panel 100. The circuit layer 150 is electrically connected to the touch circuit unit in the touch area 114a, and the circuit layer 150 and the touch circuit unit in the touch area 114a can be simultaneously formed in the same process. In addition, the arrangement of the light shielding layer 130 can effectively cover the circuit layer 150 to prevent the circuit layer 150 from being viewed from the outside. It should be noted that although the circuit layer 150 is only represented by a single layer line in the figure, in fact, the circuit layer 150 may be a multi-layer structure, since this is a technique. The art has a structure that is well known to those of ordinary skill and will not be described in detail herein.
第一裝飾層120位於透明基板110的周邊區114b，且設置於透明基板110的第一表面112a上，其中第一裝飾層120具有相對的第一內側面122與第一外側面124，第一內側面122係面向觸控區114a。第一裝飾層120例如為黏貼膜。在設計上須考量第一裝飾層120貼附於透明基板110時的精度，故第一裝飾層120的第一外側面124與透明基板110的第一表面112a的邊緣之間會預留第一間距d1 ，以避免第一裝飾層120因貼附精度不佳而突出於觸控面板100。在本實施例中，遮光層130例如位於第一裝飾層120正投影於第二表面112b的範圍內，也就是說，第一裝飾層120可完全地遮蓋遮光層130。另外，第一裝飾層120的第一外側面124於透明基板110的第二表面112b的正投影與遮光層130的第二外側面132之間例如具有第二間距d2 。第一裝飾層120的第一內側面122於透明基板110的第二表面112b的正投影與遮光層130的第二內側面134之間例如具有第三間距d3 。The first decorative layer 120 is disposed on the first surface 112a of the transparent substrate 110, and the first decorative layer 120 has an opposite first inner side 122 and a first outer side 124, first The inner side surface 122 faces the touch area 114a. The first decorative layer 120 is, for example, an adhesive film. The precision of the first decorative layer 120 attached to the transparent substrate 110 is considered in design, so that the first outer side surface 124 of the first decorative layer 120 and the edge of the first surface 112a of the transparent substrate 110 are reserved first. The pitch d 1 is to prevent the first decorative layer 120 from protruding from the touch panel 100 due to poor adhesion accuracy. In the present embodiment, the light shielding layer 130 is located, for example, in a range in which the first decorative layer 120 is projected onto the second surface 112b, that is, the first decorative layer 120 can completely cover the light shielding layer 130. In addition, the first outer side surface 124 of the first decorative layer 120 has a second pitch d 2 between the orthographic projection of the second surface 112b of the transparent substrate 110 and the second outer side surface 132 of the light shielding layer 130, for example. The first inner side surface 122 of the first decorative layer 120 has a third spacing d 3 between the orthographic projection of the second surface 112b of the transparent substrate 110 and the second inner side surface 134 of the light shielding layer 130, for example.
另一方面，第二裝飾層140位於透明基板110的周邊區114b，且設置於透明基板110的第二表面112b上。第二裝飾層140包括第一部分142與第二部分144，第一部分142連接遮光層130的第二外側面132，第二部分144連接遮光層130的第二內側面134。雖然圖2A繪示第一部分142及第二部分144皆鄰接遮光層130的邊緣，請再參照圖2B，其繪示沿圖1之剖面線A-A’的剖面示意圖的另一實施例。在圖2B中，第一部分142’與第二部分144’可延伸疊置於遮光層130之遠離透明基板110的表面，進一步還可延伸疊置部分線路層150之遠離透明基板110的表面，但不以此為限。On the other hand, the second decorative layer 140 is located on the peripheral region 114b of the transparent substrate 110 and disposed on the second surface 112b of the transparent substrate 110. The second decorative layer 140 includes a first portion 142 that connects the second outer side 132 of the light shielding layer 130 and a second portion 144 that connects the second inner side 134 of the light shielding layer 130. Although FIG. 2A illustrates that the first portion 142 and the second portion 144 are adjacent to the edge of the light shielding layer 130, please refer to FIG. 2B again, which illustrates another embodiment of a cross-sectional view along the line A-A' of FIG. In FIG. 2B, the first portion 142' and the second portion 144' may be extendedly stacked on the surface of the light shielding layer 130 away from the transparent substrate 110, and further may further extend the surface of the partial wiring layer 150 away from the transparent substrate 110, but Not limited to this.
請再次參照圖2A，第二裝飾層140的第一部分142的外側面143相較於第一裝飾層120的第一外側面124例如是更接近透明基板110的邊緣，藉此可減少透明基板110在周邊區114b的邊緣露出的面積，增加觸控面板100的外觀質感。第二裝飾層140的第一部分142與第二部分144可為印刷油墨層，但不以此為限。由於現有的印刷油墨技術的印刷精度良好，所以第二裝飾層140的第一部分142的邊緣可非常接近透明基板110的邊緣，甚至對齊透明基板110的邊緣。Referring to FIG. 2A again, the outer side surface 143 of the first portion 142 of the second decorative layer 140 is closer to the edge of the transparent substrate 110 than the first outer side surface 124 of the first decorative layer 120, thereby reducing the transparent substrate 110. The area exposed at the edge of the peripheral region 114b increases the appearance of the touch panel 100. The first portion 142 and the second portion 144 of the second decorative layer 140 may be printed ink layers, but not limited thereto. Because of the good printing accuracy of existing printing ink technologies, the edges of the first portion 142 of the second decorative layer 140 can be very close to the edges of the transparent substrate 110, even aligned with the edges of the transparent substrate 110.
一般而言，遮光層130通常為黑色，使得觸控面板100的周邊區114b呈現的顏色為黑色。為了使周邊區114b能呈現其他顏色，本實施例係藉由與遮光層130之顏色不同的第一裝飾層120來遮蓋遮光層130，並藉由第二裝飾層140來改善第一裝飾層120無法精準遮蔽周邊區114b邊緣的問題。在本實施例中，第一裝飾層120與第二裝飾層140的顏色例如相同，以使周邊區114b能呈現相同的顏色。當然，若為了滿足其他設計需求，讓周邊區114b的色彩更加多元，第一裝飾層120與第二裝飾層140的顏色亦可不同。In general, the light shielding layer 130 is generally black, such that the peripheral region 114b of the touch panel 100 exhibits a black color. In order to enable the peripheral region 114b to exhibit other colors, the present embodiment covers the light shielding layer 130 by the first decorative layer 120 different from the color of the light shielding layer 130, and improves the first decorative layer 120 by the second decorative layer 140. The problem of the edge of the peripheral zone 114b cannot be accurately masked. In the present embodiment, the colors of the first decorative layer 120 and the second decorative layer 140 are, for example, the same so that the peripheral region 114b can exhibit the same color. Of course, if the color of the peripheral area 114b is more diverse in order to meet other design requirements, the colors of the first decorative layer 120 and the second decorative layer 140 may also be different.

Referring to FIG. 1 and FIG. 3A simultaneously, since the peripheral area 114b of the touch panel 100 may be provided with one or more function keys (function keys or may be a camera), the function keys (the function keys may be a camera) For example, by providing an opening in the light shielding layer 130, the touch circuit unit disposed in the peripheral region 114b can be disposed corresponding to the opening as a touch function key. Of course, the function key can also be a physical button set in the opening. The shape of the opening may be a shape for illustrating a specific function, and the first decorative layer 120 is also correspondingly provided with an opening. For example The first decorative layer 120 has a first opening 120a, and the light shielding layer 130 has a second opening 130a corresponding to the first opening 120a. The size of the first opening 120a is, for example, smaller than the size of the second opening 130a. In addition, the second decorative layer 140 further includes a third portion 146 located in the second opening 130a and connected to the sidewall 131 of the second opening 130a, the third portion 146 having a third opening 146a corresponding to the first opening 120a The size of the third opening 146a is smaller than the size of the first opening 120a. The shape of the third opening 146a is the shape of a function key (a function key or a camera). In this embodiment, since the shape of the function key (the function key or may be a camera) is determined by the third opening 146a of the third portion 146 of the second decorative layer 140, the first opening of the first decorative layer 120 The size of 120a may be designed to be smaller than the size of the second opening 130a of the light shielding layer 130 to avoid the problem that the first opening 120a of the first decorative layer 120 exposes the light shielding layer 130. In addition, the first portion 142, the second portion 144, and the third portion 146 of the second decorative layer 140 are, for example, printed ink layers, but are not limited thereto. For example, in another embodiment, the first portion 142 and the second portion 144 of the second decorative layer 140 may be a printing ink layer, and the third portion 146 of the second decorative layer 140 is pasted to the second surface 112b. membrane. In addition, please refer to FIG. 3B, which illustrates another embodiment of a cross-sectional view along section line B-B' of FIG. 1. In FIG. 3B, the first portion 142', the second portion 144', and the third portion 146' may be extended to be superposed on the surface of the light shielding layer 130 away from the transparent substrate 110, and further extend the overlapping portion of the wiring layer 150. The surface of the transparent substrate 110 is not limited thereto.
