Description

触控显示面板及触控显示装置 技术领域
本申请涉及显示领域,特别涉及一种触控显示面板及触控显示装置。
背景技术
目前触控显示行业的发展趋势朝着窄边框的方向发展,窄边框设计可以使显示屏的显示区的尺寸增大,给用户带来更好的视觉美感。
对于集成触控功能的触控显示装置来说,其边框效果由覆盖玻璃板的边框部分、触控面板的边框部分(周边走线区)、以及触控显示面板上的边框部分(周边电路和封装区)决定。其中,覆盖玻璃板的边框部分和触控显示面板上的边框部分的都有足够的空间实现窄边框设计。而触控面板的边框部分主要是由触控走线排布而成,因触控走线的线宽和线间距的限制导致信号线总宽度的窄边框设计具有局限性。一方面,导致触控显示面板的边框部分很难有较好的窄边框效果;另一方面,由于触控走线需在绑定区进行汇总,较多的走线排布导致绑定区无法进行缩小,进一步限制了显示面板的窄边框设计。
因此,目前亟需一种触控显示面板及触控显示装置以解决上述问题。

所述触控层包括触控图案层21、绝缘层22以及桥接层23。
所述触控图案层21至少包括两条触控电极组,每条所述触控电极组至多引出两条触控走线232;
在触控状态下,所述触控电极组通过所述触控走线232将所述触控电极的触控信号传递至绑定区100a的金属走线31,再由金属走线31传递给柔性线路板上的触控IC。
在一种实施例中,所述触控图案层21包括横纵交错排列的第一触控电极组21a和第二触控电极组21b;
其中,所述第一触控电极组21a包括至少两个第一触控电211极,所述第二触控电极组21b包括至少两个第二触控电极212。
在一种实施例中,所述触控电极213为金属网格状电极和氧化铟锌电极块中的其中一者。
在一种实施例中,所述第一触控电极211为发射电极,所述第二触控电极212为接收电极。
所述绝缘层22设置在所述桥接层23和所述触控图案层21之间。
在一种实施例中,所述绝缘层22的制备材料包括氮化硅、氧化硅和氮氧化硅中的至少一者。
所述桥接层23包括桥接单元231和触控走线232,通过将桥接单元231和触控走线232同层设置,使得桥接单元231和触控走线232在同一道制程中制备,能够简化触控显示面板100的生产工艺。
请参阅图2,图2为本申请第二实施例提供的触控显示面板100的剖面图。
在一种实施例中,相邻所述第一触控电极211之间通过所述桥接单元231连接。
在一种实施例中,所述绝缘层22内设置有过孔结构以将桥接单元231和第一触控电极211连接。
其中,所述触控走线232从所述触控区100b靠近所述绑定区100a的一侧引出。
通过将触控走线232从所述触控区100b靠近所述绑定区100a的一侧引出,使得所述触控走线232在触控区100b进行排布,避免触控走线232在触控区100b外占用较大空间,实现触控显示面板100的窄边框设计。
在一种实施例中,为了避免触控走线232在触控区100b内排布影响产品的出光,所述触控走线232的制备材料包括氧化铟锌,氧化铟锡是一种透明的半导体导电材料。
在一种实施例中,所述桥接层23的制备材料为氧化铟锌。
在一种实施例中,相邻触控走线232之间相互绝缘。
在一种实施例中,所述触控电极组包括至少两个相互连接的触控电极213;
其中,每条所述触控走线232仅与一组所述触控电极组相对应,且由所对应所述触控电极组中的一个所述触控电极213引出。
请参阅图3,图3为本申请第三实施例提供的触控显示面板100的剖面图。
在一种实施例中,所述触控走线232包括相互连接的第一连接部232a和第二连接部232b;
其中,所述第一连接部232a设置在所述触控电极213表面,所述第二连接部232b与所述触控电极213之间设置有所述绝缘层22。
在一种实施例中,所述第一连接部232a在触控电极213上,沿所对应的触控走线232内的最长直线位置排布。因为所述第一连接部232a应尽可能多的与所述对应的触控电极213接触,以防止触控触控走线232发生断线。
在一种实施例中,为了方便触控走线232在触控走线232的排布,我们设置所述第二连接部232b在所述触控区100b的中部聚集,并从所述触控区100b靠近所述绑定区100a的一侧引出。再者,这样的设计也可避免触控走线232从触控区100b引出时较为分散导致边框面积过大的问题。
在一种实施例中,所述桥接单元231用以实现触控电极组内触控电极213的连接,而触控走线232用以实现触控电极213和柔性线路板的连接。因此,所述触控走线232与所述桥接单元231之间相互绝缘设计。所述触控走线232在经过设置有桥接单元231的位置时,应采用绕线设置,避开所述桥接单元231。
请参阅图4,图4为本申请第四实施例提供的触控显示面板100的剖面图。
在一种实施例中,所述触控显示面板100还包括设置在所述绑定区100a的金属走线31,所述金属走线31与所述触控走线232对应设置;
其中,所述触控走线232从所述触控区100b靠近所述绑定区100a的一侧引出并与所述金属走线31连接。
在一种实施例中,所述金属走线31部分覆盖所述触控走线232,以避免所述金属走线31与所述触控走线232接触不良。
在一种实施例中,所述触控显示面板100还包括设置在所述金属走线31与柔性线路板之间的绑定垫,用以固定金属走线31与柔性线路板的连接。
根据本申请的另一个方面,还提供了一种触控显示面板100,包括偏光片和触控显示面板100;
所述触控显示面板100包括触控区100b以及位于所述触控区100b一侧的绑定区100a。
所述触控显示面板100包括:
基板10;
触控层,设置在所述基板10上,所述触控层设置在所述触控区100b,所述触控层包括:
触控图案层21,至少包括两条触控电极组,每条所述触控电极组至多引出两条触控走线232;
绝缘层22,设置在所述触控图案层21上;
桥接层23,包括桥接单元231以及所述触控走线232;
其中,所述触控走线232从所述触控区100b靠近所述绑定区100a的一侧引出。
在一种实施例中,所述触控图案层21包括横纵交错排列的第一触控电极组21a和第二触控电极组21b;
其中,所述第一触控电极组21a包括至少两个第一触控电极211,所述第二触控电极组21b包括至少两个第二触控电极212。
在一种实施例中,相邻所述第一触控电极211之间通过所述桥接单元231连接。
在一种实施例中,所述触控电极组包括至少两个相互连接的触控电极;
其中,每条所述触控走线232仅与一组所述触控电极组相对应,且由所对应所述触控电极组中的一个所述触控电极213引出。
在一种实施例中,所述触控走线232包括相互连接的第一连接部232a和第二连接部232b;
其中,所述第一连接部232a设置在所述触控电极213表面,所述第二连接部232b与所述触控电极213之间设置有所述绝缘层22。
在一种实施例中,所述第二连接部232b在所述触控区100b的中部聚集,并从所述触控区100b靠近所述绑定区100a的一侧引出。
在一种实施例中,所述桥接层23的制备材料包括氧化铟锌。
在一种实施例中,所述桥接单元231与所述触控走线232相互绝缘。
在一种实施例中,所述触控显示面板100还包括设置在所述绑定区100a的金属走线31,所述金属走线31与所述触控走线232对应设置;

有益效果:本申请将触控走线排布在触控区内,从而避免由于触控走线在触控区外排布导致的屏占比较低的问题;再者,将触控走线与桥接单元同层设计,能够简化触控显示面板的制备工艺,节约产品的生产成本。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
