Abstract
Description
本發明係關於一種觸控面板，尤指一種利用光學補償結構改變裝飾層觀看色度之觸控面板。 The present invention relates to a touch panel, and more particularly to a touch panel that uses an optical compensation structure to change the viewing chromaticity of a decorative layer.
近年來，觸控感應技術迅速地發展，許多消費性電子產品例如行動電話(mobile phone)、衛星導航系統(GPS navigator system)、平板電腦(tablet PC)、個人數位助理(PDA)以及筆記型電腦(laptop PC)等均有與觸控功能結合的產品推出。在觸控顯示裝置的結構中，一般常會於觸控顯示區的外框區域以裝飾油墨或有色光阻形成裝飾效果。然而，即便是同一類顏色例如白色，仍會因為其色純度不純(即色度座標偏移)而呈現帶有黃綠色、藍綠色、紅藍色或紅黃色等的白色顯色狀況。造成裝飾油墨/光阻的顯色之色座標偏移的原因包括有裝飾油墨/光阻本身材料以及成分的影響、用來設置裝飾油墨/光阻之玻璃基板本身的光學性質影響以及裝飾油墨/光阻形成於玻璃基板後進行其他製程對於裝飾油墨/光阻的材料影響。因此，當觸控裝置有需要特定不同的裝飾色度需求時，往往需朝開發新的裝飾油墨/光阻的材料成分、改變裝飾油墨/光阻之堆疊結構或調整相關製程參數等方向著手。然而，由於裝飾油墨/光阻有時因為製程需求會需要具有耐高溫的特性，而玻璃基板之選擇性亦有所限制，故上述的習知做法存在著開發時間冗長、開發難度高、影響製程良率以及影響製程成本等問題。 In recent years, touch sensing technology has rapidly developed, and many consumer electronic products such as mobile phones, GPS navigator systems, tablet PCs, personal digital assistants (PDAs), and notebook computers (laptop PC) and other products with touch function. In the structure of the touch display device, the decorative effect is usually formed by decorative ink or colored photoresist in the outer frame region of the touch display area. However, even a color of the same type, such as white, may exhibit a white coloration condition with yellow-green, cyan, red-blue, or red-yellow color due to impure color purity (i.e., chromaticity coordinate shift). The causes of the color shift of the decorative ink/resistance color include the influence of the decorative ink/photoresist material and the composition, the optical properties of the glass substrate itself used to set the decorative ink/resistance, and the decorative ink/ After the photoresist is formed on the glass substrate, other processes are performed to influence the material of the decorative ink/resistance. Therefore, when a touch device needs a specific decorative color requirement, it is often necessary to develop a new decorative ink/resist material composition, change the decorative ink/light resistance stack structure, or adjust related process parameters. However, since the decorative ink/photoresist may sometimes have high temperature resistance characteristics due to process requirements, and the selectivity of the glass substrate is also limited, the above-mentioned conventional practices have long development time, high development difficulty, and affect the process. Yield and impact on process costs.

The thickness of the compensation structure 130 is, for example, between 400 angstroms and 1000 angstroms to bias the color of the first substrate 110 toward reddish blue (chromaticity coordinates a*>0, b*<0). In addition, for example, if the color of the white decorative layer 120 is reddish blue (chromaticity coordinates a*>0, b*<0), if the appearance color is to be biased toward the origin of the color coordinate center, the thickness can be utilized. a first optical compensation layer 131 formed of a tantalum nitride material between 100 angstroms and 1000 angstroms, and a second optical compensation layer 132 formed of a yttria material having a thickness of between 100 angstroms and 800 angstroms, Used to make the color of the first substrate 110 Deviating to yellow-green (chromaticity coordinates a*<0, b*>0), thereby generating a mutual compensation effect such that the chromaticity coordinates of the viewing color of the decorative layer 120 on one side of the first surface 110A approach the color coordinates Center origin. However, the present invention is not limited to the above-described material thickness matching manner. In other embodiments of the invention, a single layer optical compensation structure 130 such as a single layer of tantalum nitride material layer may be used, and the thickness of the optical compensation structure 130 may be controlled. For example, between 800 angstroms and 1000 angstroms, the color of the first substrate 110 is biased toward yellow-green (chromaticity coordinates a*<0, b*>0). In other words, the optical compensation structure 130 of the present invention can be used to improve the viewing color purity of the decorative layer 120 in addition to changing the viewing chromaticity of the decorative layer 120, that is, the optical compensation structure 130 can be used to compensate for the decorative layer.

請參考第10圖。第10圖繪示了本發明之第六實施例之觸控面板600的示意圖。如第10圖所示，與上述第四實施例不同的地方在於，本實施例之光學補償結構130係設置於第一基板110之第一面110A之一側上，且第 一光學補償層131係設置於第二光學補償層132與第一基板110之間。光學補償結構130係於垂直第一基板110之垂直投影方向Z上與裝飾層120重疊，用以改變裝飾層120於第一面110A之一側上的觀看顏色之色度座標。 Please refer to Figure 10. FIG. 10 is a schematic diagram of a touch panel 600 according to a sixth embodiment of the present invention. As shown in FIG. 10, the optical compensation structure 130 of the present embodiment is disposed on one side of the first surface 110A of the first substrate 110, and is different from the fourth embodiment. An optical compensation layer 131 is disposed between the second optical compensation layer 132 and the first substrate 110. The optical compensation structure 130 is overlapped with the decorative layer 120 in the vertical projection direction Z of the vertical first substrate 110 for changing the chromaticity coordinates of the viewing color of the decorative layer 120 on one side of the first surface 110A.
請參考圖11。第11圖繪示了本發明之第七實施例之觸控面板700的示意圖。如第11圖所示，在本實施例中，可同時利用光學補償結構130部分設置於第一基板110與觸控元件140之間，用以降低觸控元件140於第一基板110之第一面110A之一側上的圖案明顯度。在裝飾區R2中可以僅有第一光學補償層131位於裝飾層120與第一基板110之間，且裝飾層120位於第一光學補償層131與第二光學補償層132之間。另外，第一光學補償層131與第二光學補償層132設置於第一基板110與觸控元件140之間，可用以降低觸控元件140於第一基板110之第一面110A之一側上的圖案明顯度。換句話說，第一光學補償層131係於裝飾區R2設置於裝飾層120與第一基板110之間，裝飾層120係設置於第一光學補償層131與第二光學補償層132之間，且第一光學補償層131與第二光學補償層132係於透光區R1設置於第一基板110與觸控元件140之間。在本實施中第一光學補償層131較佳可以是折射率大於第二光學補償層132的材料，但並不以此為限，舉例來說，第一光學補償層131可包括氮化矽(SiNx)、氧化鈮(例如五氧化二鈮，Nb2O5)、氧化鈦(例如二氧化鈦，TiO2)或其他適合之具有所需光學特性的材料，而第二光學補償層132可包括氧化矽(例如二氧化矽，SiO2)、氟化鎂(MgF2)或其他適合之具有所需光學特性的材料。 Please refer to Figure 11. FIG. 11 is a schematic view showing a touch panel 700 according to a seventh embodiment of the present invention. As shown in FIG. 11 , in the embodiment, the optical compensation structure 130 can be partially disposed between the first substrate 110 and the touch component 140 to reduce the first touch component 140 on the first substrate 110 . The pattern on one side of the face 110A is noticeable. In the decorative area R2, only the first optical compensation layer 131 may be located between the decorative layer 120 and the first substrate 110, and the decorative layer 120 is located between the first optical compensation layer 131 and the second optical compensation layer 132. In addition, the first optical compensation layer 131 and the second optical compensation layer 132 are disposed between the first substrate 110 and the touch element 140, and can be used to reduce the touch element 140 on one side of the first surface 110A of the first substrate 110. The pattern is noticeable. In other words, the first optical compensation layer 131 is disposed between the decorative layer 120 and the first substrate 110, and the decorative layer 120 is disposed between the first optical compensation layer 131 and the second optical compensation layer 132. The first optical compensation layer 131 and the second optical compensation layer 132 are disposed between the first substrate 110 and the touch element 140 in the transparent region R1. In the present embodiment, the first optical compensation layer 131 may be a material having a refractive index greater than that of the second optical compensation layer 132, but is not limited thereto. For example, the first optical compensation layer 131 may include tantalum nitride ( SiN x ), cerium oxide (eg, antimony pentoxide, Nb 2 O 5 ), titanium oxide (eg, titanium dioxide, TiO 2 ), or other suitable material having desired optical properties, and the second optical compensation layer 132 may include oxidation Niobium (such as cerium oxide, SiO 2 ), magnesium fluoride (MgF 2 ) or other suitable materials having the desired optical properties.
綜上所述，本發明之觸控面板係利用光學補償結構之設置來改變裝飾層於觀看面上的觀看顏色之色度座標，故可不須調整裝飾層的材料或結構，並可僅藉由調整光學補償結構的材料與厚度搭配來達到調整並獲得所需之裝飾層之觀看色度的結果。此外，光學補償結構亦可用以降低觸控元件的 圖案明顯度，故可同時達到改善觸控面板外觀品質的效果。 In summary, the touch panel of the present invention utilizes the arrangement of the optical compensation structure to change the chromaticity coordinates of the viewing color of the decorative layer on the viewing surface, so that the material or structure of the decorative layer does not need to be adjusted, and only by The material and thickness of the optical compensation structure are adjusted to achieve the result of adjustment and to obtain the desired viewing color of the decorative layer. In addition, the optical compensation structure can also be used to reduce the touch element The pattern is noticeable, so the effect of improving the appearance quality of the touch panel can be achieved at the same time.
