Description

一种显示面板及显示装置 【技术领域】
本申请涉及显示技术领域,尤其涉及一种显示面板及显示装置。
【背景技术】
显示装置具有机身薄、省电、无辐射等众多优点,得到了广泛的应用。现有市场上的显示装置大部分为背光型显示装置,其包括液晶面板及背光模组(backlight module)。液晶面板的工作原理是在两片平行的基板当中放置液晶分子,并在两片基板上施加驱动电压来控制液晶分子的旋转方向,以将背光模组的光线折射出来产生画面。
其中,薄膜晶体管显示装置(Thin Film Transistor-Liquid Crystal Display,TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能,目前已经逐渐占据了显示领域的主导地位。同样,薄膜晶体管显示装置包含液晶面板和背光模组,液晶面板包括彩膜基板(Color Filter Substrate,CF Substrate,也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate,TFT Substrate),上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal,LC)。现有的液晶面板一般都是CF基板在前(在此将此处的“在前”定义为人眼20所视之处),而TFT基板在后,CF基板11中具有BM(black matrix,黑矩阵)层,也称遮光层,用于防止背景光泄漏,提高显示对比度。
TFT-LCD(Thin Film Transistor Liquid Crystal Display,薄膜晶体管显示装置)是当前平板显示的主要品种之一,已经成为了现代IT、视讯产品中重要的显示平台。TFT-LCD主要驱动原理,系统主板将R/G/B三色压缩信号、控制信号及动力通过线材与印刷板(print circuit board,PCB板)上的连接器connector相连接,数据经过PCB板上的时序控制器TCON(Timing Controller,)IC处理后,经PCB板,通过源极薄膜覆晶S-COF(Source-Chip on Film)和栅极薄膜覆晶G-COF(栅极 -Chip on Film,)与显示区连接,从而使得LCD获得所需的电源、信号。
LCD中的核心器件是薄膜晶体管阵列(TFT),而对于单个薄膜晶体管而言主要有数据信号和栅极驱动信号两种信号输入,其中栅极驱动信号起到了打开和关闭TFT的作用,其对于我们在时间上向Pixel内精确的输入数据信号起到了至关重要的作用。
随着LCD分辨率越来越高,在显示区内一条扫描线上的负载(loading)也越来越大,而负载的增大使得栅极驱动信号在传输的过程中发生的阻容延时(RC delay)也越来越严重。

下面结合附图和较佳的实施例对本申请作进一步详细说明。
如图1至3所示,本实施方式公开了一种显示面板,包括:
基板,
主动开关,形成于基板上;
多条数据线,形成于所述基板上,与主动开关耦接;
多条扫描线,形成于所述基板上,,与主动开关耦接,所述扫描线与所述数据线垂直排列,以形成多个像素区;
所述扫描线包括至少两层金属层,相邻两层金属层之间设置有绝缘层,不同金属层之间相互电容耦合。
需要说明的是,本实施例中扫描线可以包括两层金属层、三层金属层或者多种金属层,但是不限于本实施例中所列举的具体层数。
扫描线至少包括两层金属层,不同金属层相互电容耦合,通过金属层之间电容耦合效应,降低扫描线的加载压力,从而使得扫描线在传输信号的过程中降低电容电阻的延迟,使得扫描线能够准确的将信号传输到主动开关。
作为本实施例的进一步改进,其中,扫描线包括第一金属层1和第二金属层2,第一金属层1和第二金属层2电容耦合。
扫描线只有一层的情况下,如果分辨率增高,这样只有扫描线只有一层的情况下,扫描线加载也越来越大,而扫描线加载越来越大,将使得扫描线传输栅极驱动信号的过程中,电容电阻的延迟也越来越严重,这样将使得栅极驱动信号传输不能按照最初的设想一样准确的打开或者关闭,从而导致向像素电极传输输入信号时不能到达预期的效果,这样就不能达到预期的显示效果,因此,通过第一金属层1和第二金属层2相互电容耦合后,第一金属层1与第二金属层2之间会产生耦合电容,这样可以通过金属层之间电容耦合效应,降低扫描线的加载压力,从而使得扫描线在传输信号的过程中降低电容电阻的延迟,使得扫描线能够准确的将信号传输到像素电极,从而达到更好的显示效果。
作为本实施例的进一步改进,其中,显示面板包括:基板,多条数据线,形成于基板上多条扫描线,形成于基板上,扫描线与数据线垂直排列,以形成 多个像素区;扫描线包括第一金属层1和第二金属层2,第一金属层1和第二金属层2之间设有绝缘层3,第一金属层1和第二金属层2电容耦合。
第一金属层1和第二金属层2之间设有绝缘层3,这样可以阻挡杂质粒子的扩散,提高主动开关的稳定性能。
作为本实施例的进一步改进,其中,显示面板包括:基板,多条数据线,形成于基板上多条扫描线,形成于基板上,扫描线与数据线垂直排列,以形成多个像素区;扫描线包括第一金属层1和第二金属层2,第一金属层1和第二金属层2电容耦合,第一金属层1和第二金属层2可采用相同材料。
第一金属层1和第二金属层2可采用的相同的材料,这样第一金属层1和第二金属层2之间的电容耦合效果更好,能更好的降低扫描线的加载压力,从而使得扫描线在传输信号的过程中降低电容电阻的延迟,使得扫描线能够准确的将信号传输到像素电极,从而达到更好的显示效果。
作为本实施例的进一步改进,其中,显示面板包括显示面板包括:基板,形成于基板上的多条扫描线和扫描线,扫描线与数据线垂直排列,以形成多个像素区;主动开关包括栅极,栅极设在基板上,栅极上设有绝缘层,绝缘层上对应栅极设有半导体层,半导体层两端上设有分隔的主动开关的源极和漏极,源极和漏极之间设有沟道,沟道底部为半导体层。扫描线包括第一金属层1和第二金属层2,第一金属层1和第二金属层2分别与栅极耦接,栅极仅为单层金属层。
作为本实施例的进一步改进,其中,显示面板包括显示面板包括:基板,形成于基板上的多条扫描线和扫描线,扫描线与数据线垂直排列,以形成多个像素区;主动开关,主动开关包括栅极,栅极设在基板上,栅极上设有绝缘层,绝缘层上对应栅极设有半导体层,半导体层两端上设有分隔的主动开关的源极和漏极,源极和漏极之间设有沟道,沟道底部为半导体层。扫描线包括第一金属层1和第二金属层2,第一金属层1和第二金属层2分别与栅极耦接,栅极包括第一栅极金属层和第二栅极金属层,第一金属层1与第一栅极金属层耦接, 第二金属层2与第二栅极金属层耦接。

第一金属层1和第一引脚直接连接,第二金属层2与第二引脚直接连接,这样在生产制造时,生产工艺更加简单。
作为本实施例的进一步改进,其中,显示面板包括显示面板包括:基板,形成于基板上的多条扫描线和扫描线,扫描线与数据线垂直排列,以形成多个像素区;显示面板还包括栅极驱动电路4,第一金属层1和第二金属层2与栅极驱动电路4的同一引脚耦接。
第一金属层1和第二金属层2共用一个引脚进行耦接,这样在信号传输到第一金属层1和第二金属层2时,能够同时输入到第一金属层1和第二金属层2,从而达到电容耦合的作用。
作为本实施例的进一步改进,其中,显示面板包括:基板,形成于基板上的多条扫描线和扫描线,扫描线与数据线垂直排列,以形成多个像素区;扫描线包括第一金属层1和第二金属层2,扫描线的第一金属层1和第二金属层2平行设置,第一金属层1和第二金属层2之间设有绝缘层3,绝缘层3采用氮化硅或氧化硅,显示面板还包括主动开关,主动开关包括栅极,栅极设在基板上,栅极上设有绝缘层,绝缘层上对应栅极设有半导体层,半导体层两端上设有分隔的主动开关的源极和漏极,源极和漏极之间设有沟道,沟道底部为半导体层。第一金属层1和第二金属层2分别与栅极耦接,栅极包括第一栅极金属层和第二栅极金属层,第一金属层1与第一栅极金属层耦接,第二金属层2与第二栅极金属层耦接。
通过金属层之间电容耦合效应,降低扫描线的加载压力,从而使得扫描线在传输信号的过程中降低电容电阻的延迟,使得扫描线能够准确的将信号传输 到像素电极,而传统的栅极绝缘层3采用二氧化硅薄膜,这种绝缘层3阻挡杂质粒子扩散的能力很差,从而大大降低了主动开关的稳定性能,而氮化硅或氧化硅薄膜除了优秀的电学性能外,还具有较大的介电常数及更强的阻挡钠离子扩散以及水汽渗透以及其他杂质粒子扩散的能力。
