以下各实施例的说明是参考附加的图示,用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语,例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本申请,而非用以限制本申请。在图中,结构相近的单元是用以相同标号表示。
本申请实施例提供一种显示面板和电子设备,用以解决现有显示面板边框宽度不能进一步缩减的技术问题。
本申请实施例的显示面板包括显示触控区和边框区,边框区包括弯曲区和绑定区,显示面板包括驱动电路层、发光功能层和触控功能层;驱动电路层形成有驱动电路;触控功能层形成有触控电路;在边框区内,显示面板包括第一导电层和第二导电层,驱动电路通过第一导电层电连接位于绑定区内的绑定端子,触控电路通过第二导电层跨越弯曲区后通过第一导电层连接位于绑定区的绑定端子。
如图4至图6所示,图4为本申请实施例显示面板下边框结构示意图,图5是图4的A’-A’方向上的剖面图;图6是图4的B’-B’方向上的剖面图。显示面板包括显示触控区1和边框区2,边框区2包括弯曲区21和绑定区22,显示面板具体包括驱动电路层100、发光功能层200和触控功能层300;驱动电路层100形成有驱动电路;触控功能层300形成有触控电路;在边框区2内,显示面板包括第一导电层201和第二导电层202,驱动电路通过第一导电层201电连接位于绑定区22内的绑定端子221,触控电路通过第二导电层202跨越弯曲区21后通过第一导电层201连接位于绑定区22内的绑定端子221。
基于图4的布局方向,在本申请实施例中,边框区2为位于显示触控区1的下方。基于图5和图6的方向,在将显示面板组装到电子设备(例如手机、平板电脑)中时,沿着弯曲区21将边框区2向下弯折,最后在电子设备中呈现出的显示面板的下边框宽度h就是弯曲区21上端与显示触控区1下端的间距。
如图1至图3所示,图1是现有技术显示面板下边框结构示意图,图2是图1的A-A方向上的剖面图,图3是图1的B-B方向上的剖面图。现有技术中,一般将第二导电层202在弯曲区21的上方换线到第一导电层201,因为存在这个换线结构,导致显示面板弯曲后的下边框的宽度h无法进一步的缩小。
本申请实施例中,驱动电路通过第一导电层201电连接位于绑定区22内的绑定端子221,触控电路通过第二导电层202跨越弯曲区21后通过第一导电层201连接位于绑定区22的绑定端子221。这样触控电路不需要换线到驱动电路层,可以省去第二导电层202在弯曲区21换线到的第一导电层201的这段距离,使显示面板的弯曲区21可以更靠近显示触控区1,在边框区2域弯折后,显示触控区1的边缘与边框区2的间距更小,达到显示面板的边框更窄的效果。
在弯曲区21内,第一导电层201位于第二导电层202进行弯曲的一侧,且第一导电层201设为定电压信号电路。这样保证触控电路的触控信号和驱动电路的驱动信号可以稳定的传输。
第二导电层202包括触控电路连接部和绑定端子连接部,触控电路连接部的一端与触控电路电连接,另一端与绑定端子连接部的一端在弯曲区21内连接,绑定端子连接部的另一端与绑定端子连接。这样,在显示面板弯曲时,第二导电层202在弯曲区21内沿着触控电路连接部与绑定端子连接部的连接处进行弯曲,提升弯曲区21的弯曲效果。
绑定端子连接部与触控电路连接部连接时,绑定端子连接部的走线与触控电路连接部的走线连接形成的夹角范围为30°至150°。这种角度的设置,可以使第二导电层202在弯曲后,走线还可以进行良好的连接。
绑定端子221包括驱动绑定端子2211和触控绑定端子2212,触控绑定端子2212位于绑定区22的两侧,驱动绑定端子2211位于绑定区22的中部,第一导电层201与驱动绑定端子2212电连接,第二导电层202与触控绑定端子2212电连接。这样在边框区2弯曲时,第一导电层201和第二导电层202更好的弯曲,彼此不会产生干涉。
第二导电层202与触控绑定端子连接时,第二导电层202的边缘与触控绑定端子形成的夹角范围为90°至170°。这种角度设置,使第二导电层202在弯曲时可以与绑定端子形成良好的连接。
第一导电层201位于第二导电层202的中间区域,并且第二导电层202至少一部分覆盖在第一导电层201上。这样在第一导电层201和第二导电层202弯曲时,可以更好的弯曲,并且彼此不会产生干涉。
驱动电路层100包括柔性基板110,以及在柔性基板110上,朝出光方向依次设置的阻隔层111、缓冲层112、有源层113、第一栅极绝缘层114、第一栅极115、第二栅极绝缘层116、第二栅极117、介电层118、源漏极119和平坦化层120。其中,第一栅极115位于第一栅极绝缘层114上,第二栅极绝缘层116一部分覆盖在第一栅极115上,另一部分覆盖在第一栅极绝缘层114上。第二栅极117位于第二栅极绝缘层116上,介电层118的一部分覆盖在第二栅极117上,另一部分覆盖在第二栅极绝缘层116上。
阻隔层111位于柔性基板110上,缓冲层112位于阻隔层111上,有源层113位于缓冲层112上,第一栅极绝缘层114位于有源层113上,第一栅极115位于第一栅极绝缘层114上,第二栅极绝缘层116位于第一栅极绝缘层114上且覆盖第一栅极115,第二栅极117位于第二栅极绝缘层116上,介电层118位于第二栅极绝缘层116上且覆盖第二栅极117,源漏极119位于介电层118上,平坦化层120位于介电层118上且覆盖源漏极119。
源漏极119包括源极1191和漏极1192,源极1191和漏极1192位于平坦化层120上,且均通过半导体构件与有源层连接。
介电层118、第二栅极绝缘层116和第一栅极绝缘层114上均设有通过孔,有源层113上设有源极连接区和漏极连接区,半导体构件穿过通过孔,源极1191通过半导体构件与有源层113的源极连接区连接,漏极1192通过半导体构件与有源层113的漏极连接区连接。源极连接区和漏极连接区为导体化的金属氧化物半导体材料。
阻隔层111在柔性基板110上的正投影覆盖有源层113在柔性基板110上的正投影,从而使阻隔层111能够对有源层113进行完全覆盖,防止有源层113受到光线照射,避免薄膜晶体管的阈值电压产生负漂。
本申请实施例中,在边框区2内,第一导电层201位于介电层上,并且被平坦化层覆盖。这样介电层和平坦化层对第一导电层201形成有效的保护。
本申请实施例中,在显示触控区1内,发光结构层200包括阳极层2001、以及在阳极层2001上,朝出光方向依次设置的像素定义层2002、发光层(OLED)2003和阴极层。
阳极层2001位于平坦化层120上、像素定义层2002位于阳极层2001上,发光层2003位于像素定义层2002上,阴极层位于发光层2003上。像素定义层2002分离设置形成像素开口,发光层2003对于像素开口的部分平铺在阳极层2001上,阴极层对于像素开口的部分平铺在发光层2003上,阳极层2001通过阳极过孔与薄膜晶体管层中漏极1192电性接触,源极1191与外接电源的正极相连,阴极层通过电源走线层与外接电源的负极电性连接,当阳极层2001与阴极层之间设置为2V至10V的直流电压时,阳极层2001产生空穴,阴极层产生电子,在发光层2003相遇,电子和空穴分别带负电和正电,它们相互吸引,激发发光层2003中有机材料发光,以实现显示面板的正常工作。通过控制阳极层2001与阴极层之间电压的大小,可调整发光层2003发光亮度,电压越大,亮度越高,反之越暗。依其不同的配方,可产生红、绿、蓝(R、G、B)三基色,构成基本色彩。
在边框区2内,发光功能层包括像素定义层,第二导电层202位于像素定义层上, 像素定义层对第二导电层202形成良好的支撑。
本申请实施例的显示面板还包括支撑层121、封装层400和触控绝缘层500。封装层400覆盖在像素定义层2002和发光层2003上,触控绝缘层500覆盖在触控功能层300上。支撑层121位于封装层400和发光层2003之间,为封装层400、触控功能层300及位于封装层400上的触控绝缘层500提供支撑。
本申请实施例中,触控绝缘层500具体为有机绝缘层,在显示触控区1内,有机绝缘层500覆盖在触控功能层300上;在边框区2内,有机绝缘层500覆盖在像素定义层2002上。有机绝缘层500可以对触控功能层300进行绝缘保护,避免触控信号被其他的电信号干扰,导致触控失效。
本申请实施例中,如图7所示,是本申请实施例第二导电层上触控走线的结构示意图,第二导电层202包括多个触控走线,每个触控走线包括多个弯曲部2021和多个直线部2022,弯曲部2021和直线部2022互相间隔设置。
这样可以提升触控走线的整体韧性,当第二导电层202在弯曲时,触控走线不容易折断,并且弯曲的角度也可以更大。
在一种实施例中,弯曲部2021包括第一弯曲部20211和第二弯曲部20212,第一弯曲部20211的弯曲方向与第二弯曲部20212的弯曲方向相反;一个直线部2022的一端连接第一弯曲部20211,另一端连接第二弯曲部20212。
这样可以进一步提升触控走线的整体韧性,第二导电层可以弯曲的角度更大,使弯折后的边框区宽度h更小。
基于图7所示的方向,弯曲部2021垂直方向上的长度不小于直线部2022的长度,这样可以进一步提升触控走线的整体韧性,使触控走线的弯曲角度更大。
