In addition, if the second electrode 40 serving as the touch signal driving electrode in the touch display device 104 overlaps the first electrode 30 serving as the touch signal receiving electrode in a vertical projection direction Z, the coverage area is insufficient to block the display signal. In the case of interference, a shielding conductive layer 49 may be disposed between the first electrode 30 and the first substrate 11 to avoid mutual interference between the display signal and the touch signal. The shielding conductive layer 49 is electrically insulated from the first electrode 30 and the second electrode 40, and the shielding conductive layer 49 may be electrically grounded, electrically floating, or coupled to a voltage source.

在上述實施例中，當第一軟性基材21是設置於偏光片14與顯示 器10之間(例如第一實施例以及第十實施例)，當第一軟性基材21是具有複折射率的特性，例如為聚亞醯胺(polyimide,PI)，但不以此為限，且顯示器的顯示方式是利用偏光系統設計而達到顯示效果的時候，例如是液晶顯示面板時，會因為第一軟性基材21設置於偏光片14與顯示器10之間，而對顯示器的顯示特性產生影響。請參考第19圖至第28圖，並請一併參考第1圖與第14圖。 第19圖至第23圖表示為扭轉向列型液晶顯示器(Twisted Nematic LCD)搭配廣視角膜的對比視角分佈圖以及配置第一軟性基材21為聚亞醯胺(polyimide,PI)時的對比視角分佈的變化情形，第24圖至第28圖表示為垂直配向型液晶顯示器(Vertical Alignment LCD)的對比視角分佈圖以及配置第一軟性基材21為聚亞醯胺(polyimide,PI)時的對比視角分佈的變化情形；其中聚亞醯胺的材料本身是具有厚度方向的相位延遲量Rth，而其基材平面方向的相位延遲量R0則近乎於0，其中Rth及R0的定義如下列方程式(a)與方程式(b)所示： In the above embodiment, when the first flexible substrate 21 is disposed between the polarizer 14 and the display 10 (for example, the first embodiment and the tenth embodiment), when the first flexible substrate 21 has a complex refractive index The characteristic is, for example, polyimide (PI), but not limited thereto, and the display mode of the display is to use a polarizing system design to achieve a display effect, for example, when the liquid crystal display panel is used, the first softness The substrate 21 is disposed between the polarizer 14 and the display 10 to affect the display characteristics of the display. Please refer to Figures 19 to 28, and please refer to Figures 1 and 14 together. 19 to 23 show a comparative viewing angle distribution diagram of a twisted nematic liquid crystal display (Twisted Nematic LCD) with a wide viewing angle film and a comparison when the first soft substrate 21 is made of polyimine (PI).

R0=(Nx-Ny)*d(b) R0=(Nx-Ny)*d(b)

其中Nx、Ny分別表示在基材平面上的兩個垂直方向的折射率，Nz則表示在基材厚度方向的折射率，d為基材厚度。第19圖至第28圖所代表的狀況如下，第19圖為扭轉向列型液晶顯示器搭配廣視角膜的對比視角分佈圖，第20圖至第23圖為扭轉向列型液晶顯示器搭配廣視角膜且配置第一軟性基材21時的對比視角分佈圖，其中第20圖之第一軟性基材21的相位延遲量為-50奈米，第21圖之第一軟性基材21的相位延遲量為-100奈米，第22圖之第一軟性基材21的相位延遲量為-200奈米，第23圖之第一軟性基材21的相位延遲量為-400奈米；第24圖為垂直配向型液晶顯示器的對比視角分佈圖，第25圖至第28圖為垂直配向型液晶顯示器配置第一軟性基材21時的對比視角分佈圖，其中第25圖之第一軟性基材21的相位延遲量為-50奈米，第26圖之第一軟性基材21的相位延遲量為-100奈米，第27圖之第一軟性基材21的相位延遲量為-200奈米，第28圖之第一軟性基材21的相位延遲量為-400奈米。所以由圖中可以明顯看到當Rth值小於-200奈米時，整個顯示器的對比視角分佈會有非常明顯的變化，而當Rth值介於0到-200奈米的範圍內，整個顯示器的對比視角分佈尚可接受；若再限縮Rth值到介於0到-100奈米的範圍內，可得到較輕微的對比視角分佈變化；若再進一步限縮Rth值到介於0到-50奈米的範圍內，可得到更輕微的對比視角分佈變化。 Wherein Nx and Ny respectively represent refractive indices in two perpendicular directions on the plane of the substrate, Nz represents the refractive index in the thickness direction of the substrate, and d is the thickness of the substrate. The conditions represented by Fig. 19 to Fig. 28 are as follows. Fig. 19 is a comparative viewing angle distribution diagram of a twisted nematic liquid crystal display with a wide viewing angle film, and Figs. 20 to 23 are twisted nematic liquid crystal displays with a wide viewing angle. a comparative viewing angle profile when the first soft substrate 21 is disposed on the cornea, wherein the first soft substrate 21 of FIG. 20 has a phase retardation of -50 nm, and the phase of the first flexible substrate 21 of FIG. 21 is delayed. The amount of phase retardation is -100 nm, the phase retardation amount of the first flexible substrate 21 of Fig. 22 is -200 nm, and the phase retardation amount of the first soft substrate 21 of Fig. 23 is -400 nm; Fig. 24 A comparative viewing angle distribution diagram of the vertical alignment type liquid crystal display, and FIGS. 25 to 28 are comparative viewing angle distribution diagrams when the first alignment substrate 21 is disposed on the vertical alignment type liquid crystal display, wherein the first flexible substrate 21 of FIG. The phase retardation amount is -50 nm, the phase retardation amount of the first flexible substrate 21 in Fig. 26 is -100 nm, and the phase retardation amount of the first soft substrate 21 in Fig. 27 is -200 nm. The first soft substrate 21 of Fig. 28 has a phase retardation amount of -400 nm. Therefore, it can be clearly seen from the figure that when the Rth value is less than -200 nm, the contrast distribution of the entire display will have a very significant change, and when the Rth value is in the range of 0 to -200 nm, the entire display is The contrast angle distribution is acceptable; if the Rth value is limited to a range of 0 to -100 nm, a slight contrast distribution change can be obtained; if the Rth value is further reduced to between 0 and -50 In the range of nanometers, a slight contrast change in viewing angle distribution can be obtained.

另外，在本實施例中可以在偏光片14與顯示器10之間增加一相位延遲片，利用相位延遲片的設置以補償軟性基材的相位延遲量，減少偏光片14與顯示器10之間的相位延遲量到介於0到±50奈米的範圍內，最佳的狀況是將偏光片14與顯示器10之間的相位延遲量減少到0，如此將可使整個顯示器的對比視角分佈的變化減輕到極其輕微甚至不會有變化產生。 In addition, in the embodiment, a phase retarder can be added between the polarizer 14 and the display 10, and the phase retarder is set to compensate the phase retardation amount of the flexible substrate, and the phase between the polarizer 14 and the display 10 is reduced. The amount of delay is in the range of 0 to ±50 nm, and the best condition is to reduce the amount of phase delay between the polarizer 14 and the display 10 to zero, which will reduce the variation of the contrast viewing angle distribution of the entire display. Extremely slight or even no change.

另外，當上述實施例中第一軟性基材21是設置於偏光片14上且 相對於顯示器10一側，而第一軟性基材21是具有複折射率的特性，並不會對顯示器的顯示特性產生影響，但由於單純具有偏光片的顯示器所出射的顯示光是具有線偏振特性，所以當使用者配戴太陽眼鏡(偏光元件)使用觸控顯示面板時，容易因視角的改變或是轉動顯示器而有螢幕亮度大幅下降、甚至不可視的情況發生。而當一具有複折射率特性基材的光軸(例如是慢軸或快軸)的軸向不平行一偏振光的偏振方向時，就會改變此偏振光的偏振狀態，因此當第一軟性基材21是具有複折射率的特性時，只要第一軟性基材21的光軸與偏光片14的偏振軸夾角大於0度且小於90度時，即可以改善使用者配戴太陽眼鏡下顯示螢幕不可視的情況。 In addition, in the above embodiment, the first flexible substrate 21 is disposed on the polarizer 14 and The first flexible substrate 21 has a complex refractive index with respect to the display 10 side, and does not affect the display characteristics of the display, but the display light emitted by the display having the polarizer alone has linear polarization. The characteristics are such that when the user wears the touch display panel with the sunglasses (polarizing element), it is easy to cause the brightness of the screen to be greatly reduced or even invisible due to the change of the viewing angle or the rotation of the display. When the optical axis of the substrate having the complex refractive index characteristic (for example, the slow axis or the fast axis) is not parallel to the polarization direction of the polarized light, the polarization state of the polarized light is changed, so when the first softness When the substrate 21 has a characteristic of a complex refractive index, as long as the angle between the optical axis of the first flexible substrate 21 and the polarization axis of the polarizer 14 is greater than 0 degrees and less than 90 degrees, the display of the user wearing the sunglasses can be improved. The screen is not visible.
