技术领域

背景技术
近年来，显示器已经由过去的阴极射线显像管(Cathode Ray Tube，即CRT)显示器、液晶(LCD)显示器逐渐过渡发展到有机发光二极管(Organic Light-Emitting Diode，OLED)显示器。OLED显示器可以实现柔性显示(Flexible Display)。在OLED显示面板上设置触控面板能够实现OLED显示面板的触控显示。
但是，由于设置于OLED显示面板上的触控面板中的触控电极通常采用金属网格(Metal Mesh)，所以从外部环境入射至触控电极的表面的光线会发生反射，这典型地使触控面板出光侧的光线反射率会增加7％以上，从而导致OLED显示面板在户外使用时亮度明显下降。

为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开所提供的一种触控面板及其制作方法、显示面板和显示装置作进一步详细描述。
图1为根据本公开的一个实施例中的触控面板的结构剖视图。如图1所示，该触控面板包括基底1和设置在基底1上的触控电极2。所处触控面板还包括设置在触控电极2的表面的光线处理结构3，光线处理结构3能使照射到其上的光线发生散射，以减少触控电极2的表面对光线的反射。
通过设置光线处理结构3，能够使照射到触控电极2的表面的光线发生散射，以减少触控电极2的表面对光线的反射，从而提升了采用该触控面板的显示面板的显示亮度，进而降低了采用该触控面板的显示面板在户外使用时的亮度下降程度。
在本实施例中，光线处理结构3可以包括多个凸起部31。多个凸起部31可以均匀分布于触控电极2的表面。
可选地，本实施例中，任意相邻两个凸起部31之间的间距范围为1nm～1μm，所述间距为所述两个相邻凸起部31在触控电极2上的投影间的最小距离。以这种方式，光线处理结构3能够更好地使照射到触控电极2的表面的光线发生散射，以减少触控电极2的表面对光线的反射。
在本实施例中，通过对触控电极2的表面进行粗糙度处理，使触控电极2的表面形成多个凸起部31。凸起部31使触控电极2的表面变得比较粗糙，同时使照射到触控电极2的表面的光线发生散射，从而减少触控电极2的表面对照射到其上光线的反射。通过在触控电极2的表面设置凸起部31从而减少触控电极2的表面对光线反射的具体原理遵循以下公式(1)：
Figure PCTCN2018071076-appb-000001
在公式(1)中，R为触控电极2的表面对光线的反射系数；k为触控电极2的表面对光线的吸收系数；s为触控电极2的表面对光线的散射系数；f(R)为触控电极2的表面对光线的反射率。从公式(1)中可以看出，触控电极2的表面对光线的散射系数越大，则触控电极2的表面对光线的反射率越小。由于触控电极2的表面的粗糙度越高，则触控电极2的表面对光线的散射系数越高，即触控电极2的表面的散射系数会随着触控电极2的表面粗糙度的增加而增加，所以触控电极2的表面的粗糙度越高，则其对光线的反射率越小。因此，通过使触控电极2的表面变得粗糙，能够使照射到其上的光线发生散射，从而减少触控电极2的表面对光线的反射，进而提高采用该触控面板的显示面板的显示亮度。
另外，光线处理结构3的材料可以与触控电极2的材料相同。触控电极2的表面设置凸起部31不仅增加了触控电极2的表面的粗糙度，而且还增加了触控电极2的表面的面积。存在如下公式(2)：Ω＝ρ(L/A)；其中，Ω为触控电极2的电阻；ρ为电阻率；L为触控电极2的长度；A为触控电极2的表面的面积。可见，随着触控电极2的表面的面积的增加，触控电极2的电阻减小。同时，还存在公式(3)：C＝ε(A/d)；其中，C为触控电极2的电容；ε为介电常数；A为触控电极2的表面的面积；d为触控电极2的厚度。可见，随着触控电极2的表面的面积的增加，触控电极2的电容增大。触控电极2的电阻减小且电容增大，能够提升触控电极2的触控感应特性，从而提升触控面板的电学特性和触控性能。
需要说明的是，凸起部31也可以采用与触控电极2不同的材料制成。例如，触控电极2可以采用金属材料制成，凸起部31可以采用氧化铟锡、其他金属材料或碳制成。这些材料制成的凸起部31同样能够使照射到其上的光线发生散射，以减少触控电极2的表面对光线的反射。
在本实施例中，凸起部31的沿垂直于触控电极2的表面的截面形状为三角形。
需要说明的是，凸起部31的沿垂直于触控电极2的表面的截面形状也可以为矩形、梯形、半圆形、半椭圆形或规则或不规则多边形等其他的任意形状。只要能确保使触控电极2的表面变得粗糙，使照射到其上的光线发生散射即可，对凸起部31的具体形状不做限定。
本实施例中，触控电极2的表面为所述触控电极的远离基底一侧4的表面。在所述触控电极的远离基底一侧4的表面设置有凸起部31，其使所述触控电极的远离基底一侧的表面变得粗糙，从而使照射到其上的光线发生散射，进而减少所述触控电极的远离基底一侧的表面对光线的反射，最终提升了采用该触控面板的显示面板的显示亮度，降低了采用该触控面板的显示面板在户外使用时的亮度下降程度。
在本实施例中，如图2所示，触控电极2的分布形状为网格状；触控电极2的材料可以包括金属材料。当然，触控电极2的分布形状也可以是其它的形状，触控电极2的材料也可以是透明导电材料，如氧化铟锡材料等。
基于触控面板的上述结构，本实施例中还提供了一种该触控面板的制作方法，包括在基底1上形成触控电极2，以及在触控电极2的表面形成光线处理结构3，光线处理结构3使照射到其上的光线发生散射，以减少触控电极2的表面对光线的反射。
在本实施例中，在触控电极2的表面形成光线处理结构3包括：采用构图工艺形成触控电极2，以及在构图工艺的刻蚀过程中对触控电极2的表面进行刻蚀处理，以在触控电极2的表面形成光线处理结构3。即，采用构图工艺(包括膜层沉积、曝光、显影和刻蚀等步骤)形成触控电极2，并且在刻蚀过程中直接对触控电极2的表面进行刻蚀处理，以使触控电极2的表面形成凸起部31。
需要说明的是，还可以通过以下方法在触控电极2的表面形成光 线处理结构3，即：首先通过打印法形成具有光线处理结构3的膜层，然后将该具有光线处理结构3的膜层压印到触控电极2的表面。即，首先采用打印的方法并采用形成触控电极2的材料形成具有凸起部31的薄膜，然后将该薄膜压印到触控电极2的表面，以使触控电极2的表面变得粗糙。
根据本公开的另一实施例，提供了一种触控面板，其与上述实施例不同的是，触控电极2的表面为所述触控电极的远离基底一侧4的表面和靠近基底一侧5的表面，如图3所示。即所述触控电极的远离基底一侧4的表面和靠近基底一侧5的表面均设置有光线处理结构3(即多个凸起部31)。所述触控电极的靠近基底一侧的表面实质上是在所述触控电极的远离基底一侧的表面相对侧的表面。
所述触控电极的靠近基底一侧5的表面上设置凸起部31能使所述触控电极的靠近基底一侧5的表面变得粗糙，从而使照射到所述触控电极的靠近基底一侧5的表面的光线发生散射，减少了触控电极2的该侧表面对光线的反射，进而提升了采用该触控面板的显示面板的显示亮度，降低了采用该触控面板的显示面板在户外使用时的亮度下降程度。
本实施例中触控面板的其他结构以及触控面板的制作方法均与上述实施例中描述的相同，此处不再赘述。
以上描述的所有实施例都具有有益效果：通过设置光线处理结构，所提供的触控面板能够使照射到触控电极的表面的光线发生散射，以减少触控电极的表面对光线的反射，从而提升了采用该触控面板的显示面板的显示亮度，进而降低了采用该触控面板的显示面板在户外使用时的亮度下降程度。
根据本公开的再一实施例，提供了一种显示面板，包括上面描述的实施例中的任一实施例提供的触控面板。
该显示面板为有机电致发光面板或液晶面板。
通过采用上面描述的实施例中的任一实施例中的触控面板，提升了该显示面板的显示亮度，特别是提升了该显示面板在户外显示时的显示亮度，从而提高了该显示面板的显示效果。
根据本公开的又一实施例，提供了一种显示装置，包括上面描述的显示面板。通过采用该显示面板，提升了该显示装置的显示效果。
本公开所提供的显示装置可以为，OLED面板、OLED电视、液晶面板、液晶电视、显示器、手机、导航仪等任何具有显示功能的产品或部件。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
