Description

触控结构及显示面板
技术领域
本发明涉及显示领域,特别涉及一种触控结构及显示面板。
背景技术
由于有智能驾驶、智能家电、便携式终端等方面的需求,柔性显示屏在近年来的各大展会上备受关注,被认为是未来显示器的重要发展方向。
液晶显示屏或是OLED显示屏由于其轻、薄、显示效果好等优点,已被广泛应用并被市场普遍接受。但市场对于显示屏的轻薄要求却是在不断提高。近年来,由其是手机制造商对整机厚度减薄的持续需求,使得其对手机屏幕(TFTLCD\OLED)的厚度持续要求减薄。这其中偏光片作为屏幕构成的主要结构之一,对偏光片的本体厚度的要求也是希望其能在保持正常功能的同时,能够越来越薄,从而减薄屏幕的整体厚度。
对此,业界不断研发,将偏光板的厚度从最初的单偏200μm左右,通过TAC及PVA结构减薄,将其整体厚度逐渐降到100μm。之后,各偏光板供应商开始探索通过将TAC更换为更薄的COP材料以进一步的降低厚度。更有甚者,通过减少TAC层来实现将其整体厚度降低到80μm左右。考虑到支持强度收缩及信赖性等问题,减少TAC层的偏光片POL多使用在带增反膜的下偏光板中,这样可以将上、下偏光板的整体厚度降到160um左右。

为实现上述目的,本发明还提供一种显示面板,包括前文所述的触控结构。
进一步地,所述显示面板还包括:基板;薄膜晶体管,设于所述基板一侧的表面;以及像素层,设于所述薄膜晶体管远离所述基板一侧的表面;其中,所述触控结构设于所述像素层远离所述薄膜晶体管一侧的表面。
本发明的技术效果在于,采用碘分子掺杂导电聚合物,提高导电聚合物的导电性能的同时,实现偏光功能。直接在所述导电聚合物上复合触控层,实现偏光层与触控层的一体化结构,减小显示面板的厚度,提升显示面板的性能。

具体实施方式
以下结合说明书附图详细说明本发明的优选实施例,以向本领域中的技术人员完整介绍本发明的技术内容,以举例证明本发明可以实施,使得本发明公开的技术内容更加清楚,使得本领域的技术人员更容易理解如何实施本发明。然而本发明可以通过许多不同形式的实施例来得以体现,本发明的保护范围并非仅限于文中提到的实施例,下文实施例的说明并非用来限制本发明的范围。
本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是附图中的方向,本文所使用的方向用语是用来解释和说明本发明,而不是用来限定本发明的保护范围。
在附图中,结构相同的部件以相同数字标号表示,各处结构或功能相似的组件以相似数字标号表示。此外,为了便于理解和描述,附图所示的每一组件的尺寸和厚度是任意示出的,本发明并没有限定每个组件的尺寸和厚度。
当某些组件,被描述为“在”另一组件“上”时,所述组件可以直接置于所述另一组件上;也可以存在一中间组件,所述组件置于所述中间组件上,且所述中间组件置于另一组件上。当一个组件被描述为“安装至”或“连接至”另一组件时,二者可以理解为直接“安装”或“连接”,或者一个组件通过一中间组件“安装至”或“连接至”另一个组件。
如图1~2所示,本实施例提供一种触控结构,包括偏光层10及触控层20。
偏光层10用以实现偏光功能。偏光层10的材质为导电聚合物及碘分子的混合物,在本实施例中,所述导电聚合物为聚乙炔,所述聚乙炔的分子式如下:
Figure BDA0002183494370000031
每一聚乙炔中的碳原子排成两条相互平行的直线,至少两个碘分子排成一条直线,所述碘分子所在直线平行于所述聚乙炔中碳原子所在直线,此时,所述导电聚合物的导电性能最高,接近于银的导电性能。
所述碘分子掺杂在所述导电聚合物中,用以调节所述导电聚合物的导电性能。当碘分子所在直线与所述聚乙炔中碳原子所在直线平行时,所述导电聚合物的导电性能达到最佳状态,能最接近于银的导电性能。当碘分子不在同一直线排列或所述碘分子所在直线不与所述聚乙炔内的碳原子所在直线平行时,所述导电聚合物的导电性能会相对差一点,所以,碘分子的定向排列能提高所述导电聚合物的导电性能,同时,碘分子的定向排列能使得所述导电聚合物具有偏光特性,用以实现触控结构中的偏光特性。
偏光层10的厚度为0.1μm~100μm,满足现有的偏光层的厚度要求。
所述导电聚合物的强度及硬度都大于环烯烃共聚物COP及聚对苯二甲酸类塑料PET,所以,所述导电聚合物所做的偏光层10可用作触控层20的基底层,可节省基底层的使用,节约成产成本。
触控层20设于偏光层10的上表面,用以实现触控功能。触控层20包括两个以上触控电路21,触控电路21呈直线型,每两个触控电路21相互平行。
本实施例所述触控结构的技术效果在于,采用碘分子掺杂导电聚合物,提高导电聚合物的导电性能的同时,实现偏光功能。直接在所述导电聚合物上复合触控层,实现偏光层与触控层的一体化结构,减小显示面板的厚度,提升显示面板的性能。
如图3所示,本实施例还提供一种显示面板,包括基板1、薄膜晶体管2、像素层3及触控层4。
基板1为硬质基板或柔性基板,起到衬底作用。
薄膜晶体管2设于基板1的上表面,起到控制显示面板的开关电路的作用。薄膜晶体管2包括缓冲层、有源层、栅极绝缘层、栅极层、介电层、源漏极层及平坦层等,由于薄膜晶体管3为现有技术,在此不做具体阐述。
像素层3设于薄膜晶体管2的上表面,起到像素发光作用。像素层3包括阳极层、像素定义层、发光层、像素电极层等,由于像素层3都为现有技术,在此不作具体阐述。
触控结构4设于像素层3的上表面,用以实现触控功能。触控结构4即为前文所述的触控结构。
触控结构包括偏光层及触控层。
所述偏光层用以实现偏光功能。所述偏光层的材质为导电聚合物及碘分子的混合物,在本实施例中,所述导电聚合物为聚乙炔,所述聚乙炔的分子式如下:
Figure BDA0002183494370000041
每一聚乙炔中的碳原子排成两条相互平行的直线,至少两个碘分子排成一条直线,所述碘分子所在直线平行于所述聚乙炔中碳原子所在直线,此时,所述导电聚合物的导电性能最高,接近于银的导电性能。
所述碘分子掺杂在所述导电聚合物中,用以调节所述导电聚合物的导电性能。当碘分子所在直线与所述聚乙炔中碳原子所在直线平行时,所述导电聚合物的导电性能达到最佳状态,能最接近于银的导电性能。当碘分子不在同一直线排列或所述碘分子所在直线不与所述聚乙炔内的碳原子所在直线平行时,所述导电聚合物的导电性能会相对差一点,所以,碘分子的定向排列能提高所述导电聚合物的导电性能,同时,碘分子的定向排列能使得所述导电聚合物具有偏光特性,用以实现触控结构中的偏光特性。
所述偏光层的厚度为0.1μm~100μm,满足现有的偏光层的厚度要求。
所述导电聚合物的强度及硬度都大于环烯烃共聚物COP及聚对苯二甲酸类塑料PET,所以,所述导电聚合物所做的所述偏光层可用作所述触控层的基底层,可节省基底层的使用,节约成产成本。
所述触控层设于所述偏光层的上表面,用以实现触控功能。所述触控层包括两个以上触控电路,所述触控电路呈直线型,每两个触控电路相互平行。
本实施例所述显示面板的技术效果在于,采用碘分子掺杂导电聚合物,提高导电聚合物的导电性能的同时,实现偏光功能。直接在所述导电聚合物上复合触控层,实现偏光层与触控层的一体化结构,减小显示面板的厚度,提升显示面板的性能。
