Description
本創作係關於一種電容式觸控裝置,尤指一種可消除莫爾效應(Moire effect)之電容式觸控裝置。The present invention relates to a capacitive touch device, and more particularly to a capacitive touch device capable of eliminating the Moire effect.
所謂「莫爾效應(Moire effect)」是指於可觸控之顯示裝置上出現干擾顯示之波紋或條紋,其將影響整體之顯示效果,而造成使用者觀看上的困擾。The so-called "Moire effect" refers to the occurrence of ripples or streaks of interference display on a touch-sensitive display device, which will affect the overall display effect and cause user's viewing troubles.
然而,「莫爾效應(Moire effect)」形成之主要原因在於,因為電容式觸控面板需在ITO(Indium Tin Oxide;銦錫氧化物)基板上進行ITO蝕刻,以形成感應電極及導線。然而,由於ITO薄膜具有一定的厚度(約在數10nm至數百nm之間),而且感應電極及導線大都沿著垂直或水平方向進行,故當ITO感應電極或導線邊緣與液晶面板的像素、或像素邊緣黑框(Black Mask)呈現平行或垂直排列時,感應電極或導線之邊緣極易與液晶面板的像素因重疊而產生遮蔽效應,形成干擾顯示之波紋或條紋。However, the main reason for the formation of the "Moire effect" is that the capacitive touch panel requires ITO etching on an ITO (Indium Tin Oxide) substrate to form the sensing electrode and the wiring. However, since the ITO film has a certain thickness (about 10 nm to several hundreds of nm), and the sensing electrodes and the wires are mostly performed in a vertical or horizontal direction, when the ITO sensing electrode or the edge of the wire and the pixels of the liquid crystal panel, Or when the black mask of the pixel edge is arranged in parallel or vertically, the edge of the sensing electrode or the wire is easily overlapped with the pixel of the liquid crystal panel to form a shadowing effect, which forms a ripple or a stripe which interferes with the display.
此外,隨著電容式觸控螢幕大量普及,再加上觸控精度要求的不斷地提高,以及對螢幕解析度的要求也不斷地提高,使的消除莫爾效應(Moire effect)的相關技術的開發,變成產業上的一種迫切需要。In addition, with the proliferation of capacitive touch screens, the ever-increasing demand for touch accuracy, and the increasing demand for screen resolution, the related technologies that eliminate the Moire effect Development has become an urgent need in the industry.

And the arrangement direction of all the pixel units is completely shifted, thereby effectively avoiding the overlap and forming a Moire effect or a shadowing effect, which can greatly improve the display quality.
另外,請參閱圖3,圖3係本創作電容式觸控裝置第二較佳實施例之正視圖。本實施例與前述實施例主要差異在於,透明絕緣基板3上複數觸控電極4、以及複數透明導線5的佈設圖案有所不同。但是,此二實施例具備一共通特徵,如第一實施例所載,即顯示區域Da內之每一觸控電極4的每一側邊411、421、及複數透明導線5分別與第一方向D1、及第二方向D2間具有45度之夾角。In addition, please refer to FIG. 3, which is a front view of a second preferred embodiment of the capacitive touch device of the present invention. The main difference between this embodiment and the foregoing embodiment is that the layout patterns of the plurality of touch electrodes 4 and the plurality of transparent wires 5 on the transparent insulating substrate 3 are different. However, the second embodiment has a common feature, as shown in the first embodiment, that is, each side 411, 421 of each touch electrode 4 in the display area Da, and the plurality of transparent wires 5 and the first direction respectively D1 and the second direction D2 have an angle of 45 degrees.
在第二實施例中,每一感應電極41係由至少一菱形感應電極410所構成,且每一驅動電極42係由複數菱形驅動電極426串接而成。詳言之,在本實施例中,每一感應 電極41係由二菱形感應電極410串接構成,而複數菱形驅動電極426包括複數第一菱形驅動電極427、及複數第二菱形驅動電極428,且第一菱形驅動電極427之面積係小於第二菱形驅動電極428之面積,每一驅動電極42係由複數第一菱形驅動電極427、及複數第二菱形驅動電極428彼此間隔地串接構成。In the second embodiment, each of the sensing electrodes 41 is formed by at least one diamond-shaped sensing electrode 410, and each of the driving electrodes 42 is formed by serially connecting a plurality of diamond-shaped driving electrodes 426. In detail, in this embodiment, each sensor The electrode 41 is composed of a plurality of diamond-shaped sensing electrodes 410 connected in series, and the plurality of diamond-shaped driving electrodes 426 includes a plurality of first diamond-shaped driving electrodes 427 and a plurality of second diamond-shaped driving electrodes 428, and the area of the first diamond-shaped driving electrodes 427 is smaller than the second The area of the diamond drive electrode 428 is composed of a plurality of first diamond drive electrodes 427 and a plurality of second diamond drive electrodes 428 connected in series with each other.
據此,第二實施例同樣可使每一觸控電極4之每一側邊411、421、以及每一透明導線5皆呈現為不與液晶面板2之每一像素單元21的像素邊緣黑框、及所有像素單元之排列方向平行。換言之,電容式觸控裝置1上所有圖案化的透明導電結構均不會與液晶面板2上的像素單元21的像素邊緣黑框或排列之行列邊緣有重疊之情形發生,故可有效避免重疊而形成莫爾效應(Moire effect)或遮蔽效應,可大幅提高顯示品質。Accordingly, the second embodiment can also make each side edge 411, 421 of each touch electrode 4 and each transparent wire 5 appear as a black frame with no pixel edge of each pixel unit 21 of the liquid crystal panel 2. And all the pixel units are arranged in parallel. In other words, all the patterned transparent conductive structures on the capacitive touch device 1 do not overlap with the black edges of the pixel edges of the pixel units 21 on the liquid crystal panel 2 or the aligned rows and columns, so that overlapping can be effectively avoided. Forming a Moire effect or a shadowing effect can greatly improve the display quality.
