Abstract

一种显示器面板,包含:一第一电源线的一第一区段(206)及一第二电源线的一第一区段(208)、一有源区域(201)及一非显示区域(202)、一弯折区域(203)、一扇型走线区域(204)及一元件设置区域(205);第一电源线的第一区段(206)连接至元件设置区域(205)的第一电源线的一第二区段(209);及第二电源线的第一区段(208)通过设置在弯折区域(203)上的至少一组多条第二连接子线(207)连接至元件设置区域(205)的第二电源线的一第二区段(213)。通过改变显示器面板的电源线结构,并利用多条第二连接子线(207)跨接,因而可将部分走线弯折到显示器面板背面,进而实现显示器下边框的窄边框结构。

Description

显示器面板 技术领域
本发明是有关于一种显示器面板,特别是有关于一种可弯折窄边框的显示器面板。
背景技术
现今,显示器面板产业发展出,例如,有源矩阵有机发光二极体(Active-matrix organic light-emitting diode, AMOLED),具有自发光性,当有电流通过时有机材料就会发光,因此不需要另外设置背光模组。再者,显示器面板可以采用非常薄的有机材料涂层及玻璃基板,因此显示器面板可以较传统显示器的厚度薄,另外还有视角广、色饱和度高、高对比、驱动电压低、功耗低、反应快、重量轻、构造简单、成本低等优点。
中国实用新型专利公告第205140985U号提出一种柔性AMOLED显示面板结构包含第一基板及第二基板,第二基板为保护盖板,在第一基板上包含显示区域、非显示区域,非显示区域分布在显示区域四周并且左右对称,非显示区域上的控制器连接接口的各端点通过金属走线结构连接显示区域中的各数据线,所述金属走线结构包括弯折走线区域及扇型走线区域,每条弯折走线区域内的金属走线及扇形走线区域内的金属走线一一对应连接。如此通过改变柔性AMOLED显示面板的金属走线结构,使得弯折走线区域的金属走线及扇形走线区域的金属走线的电阻更加均匀,提高显示区域在整个显示面板中所占的比例,增大显示区域的面积。
请参照图1所示,其揭示一种现有智能手机1的显示器面板,包含一显示器面板100,所述显示器面板100包含一显示区域101及一非显示区域102,所述非显示区域102分布在所述显示区域101四周并且左右对称,一元件设置区域103设置于所述显示区域101的下方,用于设置多条走线(未图示)及至少一控制芯片105。接着,请参照图2所示,于所述元件设置区域103,设置有一扇形走线区104,具有多条走线用于透过所述多条走线将所述显示区域101与一控制芯片105相连接,以藉由所述控制芯片105控制所述显示区域101。再者,于所述元件设置区域103更设置有一高电位电源线106于所述显示区域101下方,以向所述显示区域101提供高电位电压。所述显示区域101周围具有一低电位电源线107围绕所述显示区域101,并下延伸于所述高电位电源线106的外侧且在所述高电位电源线106的下方内缩,进而平行于所述高电位电源线106设置后,向下走线连接至所述控制芯片105。
技术问题
然而,所述显示器面板100在实际使用上仍具有下述问题,例如:现有智能手机1的下边框,往往会有一个非显示区域,以使得所述显示器面板100在下方的所述非显示区域102预留空间以设置所述多条走线及所述控制芯片105,造成现有智能手机无法实现窄边框的设计。
如前述的背景技术中,将非显示区域向后弯折。但如将非显示区域向后弯折,则弯折区需设置在金属铺设较少的区域(例如,低电位电源线与高电位电源线呈上下两列平行并排设置,所述弯折区域则需设置在让开低电位电源线与高电位电源线的区域。如上述的背景技术为例则设置在低电位电源线与高电位电源线及所述控制芯片之间,如线BL所示),以避免金属走线断裂或与金属走线相连的非金属层脱层。如此仍具有些许边框(设置低电位电源线与高电位电源线),而无法实现真正的窄边框设计。因此,如欲实现最窄边框的设计,所述弯折区域则需设置在靠近所述高电位电源线处,但弯折可能会导致所述高电位电源线的脱层因而造成产品信赖性的问题。更严重者,可能导致设置于弯折区域的走线断裂,造成产品失效。
故,有必要提供一种显示器面板,以解决现有技术所存在的问题。使得显示器面板的下边框能够实现真正窄边框的设计,且避免窄边框而造成产品信赖性问题或走线断裂而造成产品失效。

本发明将于下文利用图3至4逐一详细说明第一实施例上述各元件的细部构造、组装关系及其运作原理。
请参照图3所示,本发明第一实施例的显示器面板主要包含一显示器模块200,所述显示器模块200可以为一玻璃基板或一有机基板,在所述显示器模块200上形成有一有源区域201及一非显示区域202,所述有源区域201及所述非显示区域202形成于所述玻璃基板或有机基板上,所述有源区域201包含多个薄膜电晶体(thin-film transistor)以控制所述显示器的发光。本实施例中,所述显示器面板为一柔性有机发光显示器面板。所述非显示区域202设置于所述有源区域201周围并向下依序延伸形成一弯折区域203、一扇型走线区域204及一元件设置区域205。所述元件设置区域205具有多个元件连接接口211。于本发明第一实施例中,所述非显示区域是通过一聚酰亚胺(polyimide, PI)基板形成。于所述有源区域201具有多条数据线204A与所述多个薄膜电晶体相连接,并延伸经过所述弯折区域203及所述扇型走线区域204。换句话说,所述扇型走线区域204包含多条金属走线(未图示),其中部分的所述多条金属走线为所述多条数据线204A。所述多条金属走线可以为所述多个薄膜电晶体的栅极线。所述多条数据线204A连接所述有源区域201及所述多个元件连接接口211,所述多个元件连接接口211用于连接一电子元件212。例如连接一控制器芯片。在其他实施例中,所述多个元件连接接口211可以利用软硬结合板的技术与一硬板接合。所述电子元件212可以为通过封装后的封装单元,也可以为一裸芯透过倒装芯片的方式通过多个凸块连接所述多个元件连接接口211。所述电子元件212更可替换成其他电子零件,如无源部件等。在一个实施例中,位于所述弯折区域的所述第一连接子线、所述第二连接子线及所述多条数据线由的材料由钛铝钛或钼、铜、纳米银线中的一种组成。
请参照图3所示,本发明第一实施例的显示器面板,在所述有源区域201周围的所述非显示区域202设置有一第一电源线的一第一区段206,所述第一电源线的所述第一区段206的形状为搭配所述有源区域201的形状而设计,以缩小显示器的边框。所述第一电源线的所述第一区段206于本实施例为一低电位电源线(VSS),所述第一电源线的所述第一区段206连接至所述元件设置区域205的第一电源线的两个第二区段209。本实施例中,所述第一电源线的所述第一区段206分别以设置在所述弯折区域上的多条第一连接子线210连接所述第一电源线的所述第二区段209。所述第一电源线的所述第一区段206的一线径及所述第一电源线的所述第二区段209的一线径大于所述第一连接子线210的一线径。所述第一连接子线210的一线径不大于20微米,例如为1微米至20微米;及所述第一连接子线210的一线距为3微米至8微米。本实施例中,例如所述第一电源线的所述第一区段206的线径为200微米,所述多条第一连接子线210的线径为15微米且所述第二连接子线的线距为5微米。换句话说,所述第一电源线的所述第一区段206连接至所述第一电源线的所述第二区段209可通过一组十条第一连接子线210连接。如此,在所述弯折区域203延着BL线弯折时,所述多条第一连接子线210可分散应力,以避免导线断裂及金属层与非金属层脱层。再者,如有部分第一连接子线210断裂,仍有其他的部分第一连接子线210连接,而不会造成产品失效。其他实施例中,所述第一电源线的所述第一区段的两端可分别以一金属网格形式的镂空走线所述第一电源线的所述第二区段209连接所述多个元件连接接口211。其他可以增加导线柔软度,避免导线断裂及金属层与非金属层脱层的实施方式均考量在内。所述第一电源线的所述第一区段206左右两侧的线径大于所述第一电源线的所述第一区段206上下两侧的线径。于所述第一电源线的所述第一区段206纵向走线转向所述第一电源线的所述第一区段206横向走线时,所述第一电源线的所述第一区段206系为渐缩的形式(例如于所述第一电源线的所述第一区段206纵向走线线径为300微米,而转向所述第一电源线的所述第一区段206横向走线后渐缩为150微米)。如此,可以进一步压缩所述显示器下边框。
请参照图3所示,本发明第一实施例的显示器面板,一第二电源线的一第一区段208设置于所述有源区域201下方,并设置在所述有源区域201及所述弯折区域203之间。本实施例中,所述第二电源线的所述第一区段208为一高电位电源线(VDD)。所述第一电源线的所述第一区段206与所述第二电源线的所述第一区段208彼此平行且位于一相同的延伸线上。所述第二电源线的所述第一区段208通过至少一组多条第二连接子线207经过所述弯折区域203而连接至所述元件设置区域205的一第二电源线的一第二区段213,所述第二电源线的所述第二区段213位于所述扇型走线区域204的上方。所述第二电源线的所述第二区段213连接至所述多个元件连接接口211。所述第二电源线的所述第一区段208与所述第二电源线的所述第二区段213互相平行,及所述第二电源线的所述第一区段208的一线径小于所述第二电源线的所述第二区段213的一线径,且大于所述第二连接子线207的一线径。所述第二电源线的所述第一区段208的线径不大于150微米,例如为50微米至150微米,及所述第二电源线的所述第二区段213的线径不大于250微米,例如为150微米至250微米。所述第二连接子线207的线径不大于20微米,例如为1微米至20微米及所述第二连接子线的一线距为3微米至8微米。请参照图3A是本发明第一实施例显示器面板的局部放大示意图。本实施例中,例如所述第二电源线的所述第一区段208的线径为50微米,所述第二连接子线207的线径为15微米且所述第二连接子线的线距为5微米。所述第二电源线的所述第一区段208连接至所述第二电源线的所述第二区段213可分别通过(例如一组十条)所述第二连接子线207连接。所述第二电源线的所述第一区段208分别以两组多条第二连接子线207经过所述弯折区域203的两个区段而连接至所述元件设置区域205的所述第二电源线的所述第二区段213。本实施例中,所述第二连接子线207分别设置于所述第二电源线的所述第一区段208及所述第二电源线的所述第二区段213的两个端部处,而中间镂空区域215不铺设金属层,以降低金属层的比例,如此可以增加弯折区域的柔性。本实施例中,所述第二电源线的所述第一区段208及所述第二电源线的所述第二区段213具有相同的电位,通过所述第二连接子线207以并联的方式相互连接,使得所述第二电源线的所述第一区段208及所述第二电源线的所述第二区段213得电位能够相同。其他实施例中,所述中间镂空区域215可具有多条导孔,垂直地上下导通不同层之间的讯号。在另一个实施例中,所述第二连接子线207是以金属网状走线的方式设计,同样可以降低金属层的比例,如此可以增加弯折区域的柔性。
请参照图4所示,本发明第一实施例的显示器面板的弯折后示意图,大致沿用相同元件名称及图号,所述弯折区域203沿着BL线弯折后,所述显示器面板的下边框明显小于背景技术的下边框。
请参照图5所示,本发明第一实施例的显示器面板的弯折后侧视示意图,大致沿用相同元件名称及图号,所述弯折区域203沿着BL线弯折后,将所述显示器面板的所述元件设置区域205弯折至所述显示器的背面,所述元件设置区域205更可与一柔性电路板(Flexible Printed Circuit, FPC)214,如此可以大幅缩小所述显示器正面下边框的尺寸。
请参照图6所示,本发明第二实施例的显示器面板相似于本发明第一实施例,并大致沿用相同元件名称及图号,但第二实施例的差异特征在于:所述弯折区域203进一步增设有一左侧区段207L、一中间区段207M及一右侧区段207R,一电源线的一第一区段208分别以三组多条第二连接子线210过所述弯折区域203的所述左侧区段207L、所述中间区段207M及所述右侧区段207R而连接至所述元件设置区域20的所述电源线的一第二区段213,所述电源线的所述第二区段213连接至所述多个元件连接接口211。于一个实施例中,所述电源线可等同于上图3所述的第二电源线。上述特征的优点在于:电源线208分别以三组多条第二连接子线210过所述弯折区域203的所述左侧区段207L、所述中间区段207M及所述右侧区段207R而连接至所述元件设置区域20的所述电源线的一第二区段213。因此,不但可大幅缩短显示器面板的下边框长度进而实现全面屏显示器的设计,并可避免线路因弯折而断裂,即使部分线路断裂仍能保持产品功能,因而进一步相对增加产品可靠度及避免走线断裂而造成产品失效。
请参照图7所示,本发明第三实施例的显示器面板相似于本发明第二实施例,并大致沿用相同元件名称及图号,但第二实施例的差异特征在于:于元件设置区205除设置一电子元件212,另可设置一柔性电路板214。
本发明已由上述相关实施例加以描述,然而上述实施例仅为实施本发明的范例。必需指出的是,已公开的实施例并未限制本发明的范围。相反地,包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
