Description
本發明係關於一種觸控面板，尤指一種具有與電極層對應設置之補償層並用以改善外觀品質之觸控面板。The present invention relates to a touch panel, and more particularly to a touch panel having a compensation layer disposed corresponding to an electrode layer and used to improve the appearance quality.
觸控技術近年來蓬勃發展，許多消費性電子產品均有與觸控功能結合的產品問世。目前觸控面板的技術中較常見包括電阻式、電容式以及光學式等。其中電容式觸控面板由於具有高準確率、多點觸控、高耐用性以及高觸控解析度等特點，已逐漸成為目前中高階消費性電子產品使用之主流觸控技術。Touch technology has boomed in recent years, and many consumer electronics products have been introduced with touch functions. Currently, touch panel technology is more commonly used in the form of resistive, capacitive, and optical. Among them, capacitive touch panels have become the mainstream touch technology used in middle and high-end consumer electronic products due to their high accuracy, multi-touch, high durability and high touch resolution.
在習知的電阻式與電容式觸控面板中，一般需利用透明導電材料例如氧化銦錫(indium tin oxide,ITO)來形成透明電極以減少對所搭配之顯示裝置進行顯示時的影響。然而，氧化銦錫材料本身屬於高折射率(一般約1.7至2.0)且對光有吸收性之材料，因此於觸控面板上有無透明電極之區域容易產生視覺上的顏色差異，而造成透明感應電極圖案明顯度的問題，影響到觸控面板的外觀品質。因此，目前業界為了解決此問題，係利用於觸控面板中設置一整面的覆蓋層(overcoat)，並將覆蓋層的色度調整成與氧化銦錫相同以降低氧化銦錫圖案的明顯度。然而，在此方式下由於覆蓋層本身也為有顏色的材料，故與顯示裝置搭配時亦會有使顯示畫面產生色偏的問題。In conventional resistive and capacitive touch panels, a transparent conductive material such as indium tin oxide (ITO) is generally used to form a transparent electrode to reduce the influence on display of the displayed display device. However, the indium tin oxide material itself is a material having a high refractive index (generally about 1.7 to 2.0) and is light-absorptive, so that a region having a transparent electrode on the touch panel is liable to cause a visual color difference, thereby causing a transparent induction. The problem of the apparent pattern of the electrode pattern affects the appearance quality of the touch panel. Therefore, in order to solve this problem, the current industry uses a full-cover overcoat in the touch panel, and adjusts the chromaticity of the cover layer to be the same as that of indium tin oxide to reduce the visibility of the indium tin oxide pattern. . However, in this mode, since the cover layer itself is also a colored material, there is a problem that the display screen is colored when it is combined with the display device.
本發明之主要目的之一在於提供一種觸控面板，利用設置一與電極層具有相同圖案之補償層，藉由補償層與電極層之間色度互補的關係，降低光源之光穿過電極層以及補償層前後的顏色變化程度，進而改善觸控面板的外觀品質。One of the main purposes of the present invention is to provide a touch panel by using a compensation layer having the same pattern as the electrode layer, and reducing the light of the light source through the electrode layer by complementing the relationship between the compensation layer and the electrode layer. And the degree of color change before and after the compensation layer, thereby improving the appearance quality of the touch panel.

請參考第1圖與第2圖。第1圖繪示了本發明之一第一較佳實施例之觸控面板的示意圖。第2圖繪示了本實施例之觸控面板的頻譜示意圖。為了方便說明，本發明之各圖式僅為示意以更容易了解本發明，其詳細的比例可依照設計的需求進行調整。如第1圖所示，本實施例提供觸控面板101，包括基板110、第一電極層120以及第 一補償層130。第一電極層120係設置於基板110上。第一補償層130係設置於基板110上並與第一電極層120對應設置。第一補償層130於垂直於基板110的方向Z上與第一電極層120具有相同的圖案，以使得光穿過第一電極層120以及第一補償層130前後之色度差變化(CIEDE2000,△E00)小於1。在本實施例中，第一電極層120係設置於基板110與第一補償層130之間，且觸控面板101可更包括絕緣層140設置於第一電極層120與基板110之間。絕緣層140較佳係於垂直於基板110的方向Z上與第一電極層120具有相同的圖案。換句話說，絕緣層140、第一電極層120以及第一補償層130較佳係依序堆疊設置於基板110上且具有相同的圖案，以獲得較佳的光學補償效果。在本實施例中，穿過基板110之光與另一穿過基板110、絕緣層140、第一電極層120以及第一補償層130之光之間的色度差係小於1。此外，觸控面板101可更包括一保護層150覆蓋絕緣層140、第一電極層120以及第一補償層130，以達到保護的效果。Please refer to Figure 1 and Figure 2. FIG. 1 is a schematic view of a touch panel according to a first preferred embodiment of the present invention. FIG. 2 is a schematic diagram showing the spectrum of the touch panel of the embodiment. For the convenience of description, the drawings of the present invention are only for the purpose of understanding the present invention, and the detailed proportions thereof can be adjusted according to the design requirements. As shown in FIG. 1 , the present embodiment provides a touch panel 101 including a substrate 110 , a first electrode layer 120 , and a first A compensation layer 130. The first electrode layer 120 is disposed on the substrate 110. The first compensation layer 130 is disposed on the substrate 110 and disposed corresponding to the first electrode layer 120. The first compensation layer 130 has the same pattern as the first electrode layer 120 in the direction Z perpendicular to the substrate 110, so that the chromaticity difference changes before and after the light passes through the first electrode layer 120 and the first compensation layer 130 (CIEDE2000, ΔE00) is less than 1. In the present embodiment, the first electrode layer 120 is disposed between the substrate 110 and the first compensation layer 130 , and the touch panel 101 further includes an insulating layer 140 disposed between the first electrode layer 120 and the substrate 110 . The insulating layer 140 preferably has the same pattern as the first electrode layer 120 in the direction Z perpendicular to the substrate 110. In other words, the insulating layer 140, the first electrode layer 120, and the first compensation layer 130 are preferably stacked on the substrate 110 in the same order and have the same pattern to obtain a better optical compensation effect. In the present embodiment, the chromaticity difference between the light passing through the substrate 110 and the other light passing through the substrate 110, the insulating layer 140, the first electrode layer 120, and the first compensation layer 130 is less than one. In addition, the touch panel 101 may further include a protective layer 150 covering the insulating layer 140, the first electrode layer 120, and the first compensation layer 130 to achieve a protective effect.
在本實施例中，基板110較佳可包括硬質基板例如玻璃基板與陶瓷基板或可撓式基板(flexible substrate)例如塑膠基板或其他適合材料所形成之基板。第一電極層120較佳可包括透明導電材料例如氧化銦錫(indium tin oxide,ITO)、氧化銦鋅(indium zinc oxide,IZO)或氧化鋁鋅(aluminum zinc oxide,AZO)，但並不以此為限。第一補償層130較佳可包括無機材料例如氮化矽(silicon nitride)、氧化矽(silicon oxide)與氮氧化矽(silicon oxynitride)、有機材料例如丙烯酸類 樹脂(acrylic resin)或其它適合之材料，並利用材料本身的顏色或另外添加染料而使得第一補償層130為一帶有顏色之有色補償層，但並不以此為限。In this embodiment, the substrate 110 preferably includes a rigid substrate such as a glass substrate and a ceramic substrate or a flexible substrate such as a plastic substrate or other suitable material. The first electrode layer 120 preferably includes a transparent conductive material such as indium tin oxide (ITO), indium zinc oxide (IZO) or aluminum zinc oxide (AZO), but does not This is limited. The first compensation layer 130 may preferably include an inorganic material such as silicon nitride, silicon oxide and silicon oxynitride, and an organic material such as acrylic. An acrylic resin or other suitable material, and the first compensation layer 130 is a color-colored colored compensation layer by using the color of the material itself or additionally adding a dye, but is not limited thereto.
舉例來說，如第1圖與第2圖所示，第2圖中的曲線L1代表第一電極層120的光穿透率與光波長範圍間的關係頻譜，曲線L2代表第一補償層130的光穿透率與光波長範圍間的關係頻譜。當第一電極層120係由氧化銦錫所形成時，因氧化銦錫的材料本身具有顏色，故第一電極層120可視為黃色透明導電層而具有如第2圖中曲線L1的頻譜。在此狀況下，第一補償層130則較佳係為一藍色補償層而具有如第2圖中曲線L2的頻譜。因此，帶有藍色之第一補償層130可與帶有黃色之第一電極層120形成顏色互補的關係，使得第一電極層120與第一補償層130結合的狀況下具有如第2圖中線段L3的頻譜。也就是說，帶有藍色之第一補償層130可與帶有黃色之第一電極層120結合而使得整體看來趨近於無色偏現象以降低光源穿過第一電極層120以及第一補償層130前後的顏色變化程度，進而改善觸控面板101的外觀品質。值得說明的是，由於第一補償層130係與第一電極層120圖案相同且對應設置，基板110上未設置第一電極層120之區域亦無設置第一補償層130，故即使第一補償層130帶有顏色仍不會影響到觸控面板101整體的外觀顏色，而當本實施例之觸控面板101與其他顯示裝置搭配時亦可藉此改善對於顯示畫面產生色偏等問題。For example, as shown in FIGS. 1 and 2, the curve L1 in FIG. 2 represents the spectrum of the relationship between the light transmittance of the first electrode layer 120 and the wavelength range of the light, and the curve L2 represents the first compensation layer 130. The spectrum of the relationship between light transmittance and the wavelength range of light. When the first electrode layer 120 is formed of indium tin oxide, since the material of the indium tin oxide itself has a color, the first electrode layer 120 can be regarded as a yellow transparent conductive layer and has a spectrum as the curve L1 in FIG. In this case, the first compensation layer 130 is preferably a blue compensation layer and has a spectrum as shown by the curve L2 in FIG. Therefore, the first compensation layer 130 having a blue color may be in a complementary relationship with the first electrode layer 120 having a yellow color, such that the first electrode layer 120 is combined with the first compensation layer 130 as in FIG. The spectrum of the midline segment L3. That is, the first compensation layer 130 with blue color may be combined with the first electrode layer 120 with yellow color so that the whole appears to be close to the colorless phenomenon to reduce the light source passing through the first electrode layer 120 and the first The degree of color change before and after the compensation layer 130 improves the appearance quality of the touch panel 101. It should be noted that, since the first compensation layer 130 is identical to the first electrode layer 120 and correspondingly disposed, the first compensation layer 130 is not disposed on the region of the substrate 110 where the first electrode layer 120 is not disposed, so even the first compensation layer The color of the layer 130 does not affect the overall color of the touch panel 101. When the touch panel 101 of the present embodiment is combined with other display devices, the color shift of the display screen can be improved.
為了清楚說明本發明之第一補償層的色度與改善效果，請參考表1，表1表列出了當光源為一C光源(C-light)時光穿過各層後的色座標變化。如表1所示，當光僅穿過第一電極層時色座標發生了偏移，有顏色上的變化。而當光僅穿過第一補償層時色座標亦發生了偏移，但請注意光分別穿過第一電極層與第一補償層時所產生的偏移狀況並不一樣，也就是說第一補償層與第一電極層之顏色並不相同，而是具有顏色互補之關係。因此，光穿過第一電極層與第一補償層之後其色座標可與未穿過前的光相近，第一補償層的設置可有效降低光穿過第一電極層以及第一補償層前後之色度差變化，進而改善第一電極層圖案明顯度的問題。值得說明的是，本發明之光並不限於C光源，其他所需使用之光亦可藉以搭配並依據不同光源的性質來調整第一補償層的顏色狀況，以達到所需之光學補償效果。In order to clearly illustrate the chromaticity and improvement effect of the first compensation layer of the present invention, please refer to Table 1. Table 1 lists the color coordinate changes after the light passes through the layers when the light source is a C-light source. As shown in Table 1, when the light passes only through the first electrode layer, the color coordinates are shifted, and there is a change in color. When the light only passes through the first compensation layer, the color coordinates are also shifted, but please note that the offset generated by the light passing through the first electrode layer and the first compensation layer is not the same, that is, the first A compensation layer is not the same color as the first electrode layer, but has a complementary color relationship. Therefore, after the light passes through the first electrode layer and the first compensation layer, the color coordinates thereof are similar to the light before the first pass, and the first compensation layer is disposed to effectively reduce the light passing through the first electrode layer and the first compensation layer. The chromaticity difference changes, thereby improving the visibility of the first electrode layer pattern. It should be noted that the light of the present invention is not limited to the C light source, and other required light can be used to adjust and adjust the color condition of the first compensation layer according to the properties of different light sources to achieve the desired optical compensation effect.

綜合以上所述，本發明之觸控面板係利用帶有顏色之補償層與電極層搭配設置，藉由補償層與電極層之間色度互補的關係，降低光穿過電極層以及補償層前後的色度差變化，進而改善電極層的明顯度問題。此外，本發明之觸控面板更利用使補償層與電極層具有相同的圖案且對應設置，避免補償層影響到觸控面板的外觀顏色，故除了可改善觸控面板的外觀品質之外，亦可改善當觸控面板與顯示裝置搭配時對於顯示畫面產生色偏之現象。In summary, the touch panel of the present invention is configured by using a compensation layer with a color and an electrode layer, and reducing the relationship between the compensation layer and the electrode layer to reduce the light passing through the electrode layer and the compensation layer. The chromaticity difference changes, thereby improving the visibility of the electrode layer. In addition, the touch panel of the present invention further utilizes the same pattern and corresponding arrangement of the compensation layer and the electrode layer, so as to prevent the compensation layer from affecting the appearance color of the touch panel, in addition to improving the appearance quality of the touch panel, It can improve the phenomenon of color shift on the display screen when the touch panel is matched with the display device.
