Description
本發明與觸控面板的感測裝置有關，更特別是與觸控面板的感測裝置之光學性質改善方案有關。 The present invention relates to a sensing device of a touch panel, and more particularly to an optical property improvement scheme of a sensing device of the touch panel.
由於智慧型手機與諸多觸控裝置的普及，觸控面板係已大幅應用於各式電子設備及/或產品中。觸控面板的原理是，以手指作為帶有靜電的一種導電體，當手指碰觸面板而靠近透明電極時，電極與手指之間的電荷即發生匯集。隨著電荷的匯集，觸控面板的控制器模組即可據以測定手指和電極之間的靜電容量或電容量，並依距離面板四個角落之電流比例的不同而計算出接觸位置。 Due to the popularity of smart phones and many touch devices, touch panels have been widely used in various electronic devices and/or products. The principle of the touch panel is that the finger acts as a kind of electric conductor with static electricity, and when the finger touches the panel and approaches the transparent electrode, the electric charge between the electrode and the finger is collected. With the accumulation of charge, the controller module of the touch panel can determine the electrostatic capacity or capacitance between the finger and the electrode, and calculate the contact position according to the ratio of the currents in the four corners of the panel.
觸控面板之感測裝置的主要構成係包含感測結構、液晶模組(Liquid Crystal Module,LCM)以及控制模組所構成，其中感測結構則由玻璃基板(或強化玻璃基板)、以及位於玻璃基板上且經圖樣化之氧化銦錫(Indium Tin Oxide,ITO)透明薄膜建構而成。ITO薄膜具有光學穿透率高、導電性良好、對基板黏著性佳、易於光蝕刻加工、以及化學穩定性佳等優點，因此已漸廣泛用於各式光電類產品(特別是各式顯示應用與觸控裝置)中作為感測層之用。 The main component of the sensing device of the touch panel comprises a sensing structure, a liquid crystal module (LCM) and a control module, wherein the sensing structure is composed of a glass substrate (or a tempered glass substrate) and A patterned thin film of Indium Tin Oxide (ITO) is formed on the glass substrate.

然而，在現有的觸控面板感測結構中使用ITO薄膜並非全無缺失。舉例而言，由於ITO薄膜為偏黃色材質，因此以ITO薄膜作為感測層之用將導致感測結構的色度值(Chromaticity)受到影響，造成觸控面板感測裝置的整體色度偏黃(即具有偏高的b*值，約1.5~3)，影響顯示的感官效果。 However, the use of ITO films in existing touch panel sensing structures is not completely missing.

(ie has a high b* value, about 1.5~3), affecting the sensory effect of the display.

根據本發明，在觸控面板感測裝置中設置一偏藍色之調整層(可為光學膠或薄膜)，係可改善感應裝置之光學色度，補償ITO之偏黃色色度，達到顯示鮮明之效果。 According to the present invention, a blue adjustment layer (which may be an optical glue or a film) is disposed in the touch panel sensing device to improve the optical chromaticity of the sensing device and compensate for the yellowish chromaticity of the ITO to achieve a clear display. The effect.
本發明之調整層構想可與現有的各式觸控面板感測裝置相容而應用於其中。在實際實施態樣中，本發明之調整層可同時作為蓋板與感測結構之間的貼合機制、或是作為液晶模組與感測結構之間的貼合機制，利用摻有適當染料而呈現偏藍色之光學膠來貼合蓋板與感測結構、或貼合感測結構與液晶模組，同時改善色度、降低b*值。此外，本發明之調整層可作為防爆膜或裝飾膜、或各式薄膜(例如硬化塗層、抗反射層、抗炫層、抗指紋層等)與感測裝置之間的貼合機制，利用摻有適當染料而呈現偏藍色之光學膠來貼合這些膜材與感測結構或液晶模組，同時改善感測裝置之色度、降低b*值。 The adjustment layer concept of the present invention can be applied to various touch panel sensing devices in the prior art. In an actual implementation, the adjustment layer of the present invention can simultaneously serve as a bonding mechanism between the cover plate and the sensing structure, or as a bonding mechanism between the liquid crystal module and the sensing structure, using a suitable dye. The blue-colored optical glue is applied to fit the cover plate and the sensing structure, or to the sensing structure and the liquid crystal module, and at the same time, the chromaticity is improved and the b* value is lowered. In addition, the adjustment layer of the present invention can be utilized as an explosion-proof film or a decorative film, or a bonding mechanism between various types of films (for example, a hard coating layer, an anti-reflection layer, an anti-glare layer, an anti-fingerprint layer, etc.) and a sensing device. An optical gel that is blued with a suitable dye to conform to the film and the sensing structure or the liquid crystal module, while improving the chromaticity of the sensing device and lowering the b* value.
利用本發明之調整層的配置，確實可有效降低感測裝置的色度值b*，使感測裝置之色度值b*有效降低至1.5以下(甚至是0.7以下)，其表示感測裝置之偏黃色色度已得有效補償，使感測裝置整體呈現透明無色的鮮明顯示效果。以本發明之OGS型觸控面板感測裝置為例，在感測裝置中利用調整層(其 中OCA層厚25μm、PET基材厚75μm)作為感測結構與硬化塗層間之貼合機制、同時進行色度值調整，其光學測試實測結果係列於下表(一)。 With the configuration of the adjustment layer of the present invention, the chromaticity value b* of the sensing device can be effectively reduced, and the chromaticity value b* of the sensing device is effectively reduced to 1.5 or less (or even 0.7 or less), which represents the sensing device. The yellowish chromaticity has been effectively compensated, so that the sensing device as a whole has a clear and colorless vivid display effect. Taking the OGS type touch panel sensing device of the present invention as an example, an adjustment layer is utilized in the sensing device (its The medium OCA layer has a thickness of 25 μm and the PET substrate has a thickness of 75 μm. As a bonding mechanism between the sensing structure and the hardened coating layer, the chromaticity value is adjusted at the same time, and the optical test results are shown in the following table (1).
由表(一)中各光學性質測試結果可知，藉由本發明之調整層的作用，能夠有效降低感測裝置的b*值，同時不致影響其他光學性質，保持其穿透率、霧度與明度達一定範圍內。換言之，藉由本發明，利用偏藍色之調整層的色度加乘及/或補償作用，即可對含氧化銦錫層之感測結構進行色度值調整，可在不影響感測裝置之霧度與光穿透率等重要光學性質下，有效降低感測裝置的b*值。 It can be seen from the results of the optical properties test in Table (1) that the b* value of the sensing device can be effectively reduced by the action of the adjustment layer of the present invention without affecting other optical properties, maintaining the transmittance, haze and brightness. Within a certain range. In other words, according to the present invention, the chromaticity value adjustment of the sensing structure containing the indium tin oxide layer can be performed by using the chromaticity multiplication and/or compensation of the adjustment layer of the bluish blue layer, without affecting the sensing device. Under important optical properties such as haze and light transmittance, the b* value of the sensing device is effectively reduced.
