现有的触控显示装置通常采用低温多晶硅工艺制成,像素单元和控制电路之间通过布线(fan out)实现电性连接。触控显示装置的有源元件(TFT)阵列基板上通常形成有平坦层(PL),当采用第三金属层(M3)实现触控信号的传递以及达到降低驱动电压的功效时,在需要大范围形成第三金属层的区域,通常采用挖空平坦层的方式,由此,在相应的区域并无法形成有支撑垫(Bump)。对于现有的工艺而言,支撑垫的厚度约为5500埃,第三金属层的厚度约为3700埃,因此,在形成第三金属层的区域和未形成第三金属层的区域之间产生约1800埃的高度落差,进而,导致触控显示装置产生显示不均的问题。
因此,如何能更好地避免显示面板中不同区域高度落差的出现,减少显示不均现象的发生,提高产品的显示效果,实为需要解决的问题之一。

具体实施方式
下面结合附图对本发明的结构原理和工作原理作具体的描述:
图1A是本发明一实施例显示装置的结构示意图,图1B是图1A沿A-A’剖面线的剖视图,图1C是图1A中区域Q1的剖视示意图,图1D是图1A中区域Q2的剖视示意图。如图1A所示,显示装置100包括第一基板101、第二基板102,第一基板101与第二基板102相对设置。于本实施例中,第一基板101具有相邻的显示区AA以及周边区BA,显示区AA中设置有多个像素单元(图中未示出),多个像素单元呈阵列布置,沿着第一方向(例如X方向)排成多列,沿着第二方向(例如Y方向)排成多行,且每一像素单元中均形成有至少一薄膜晶体管(图中未示出)。第一基板上101上设置有控制电路IC,第一基板101上设置有第二金属层M2以及第三金属层M3,第二金属层M2、第三金属层M3耦接至控制电路IC,且第二金属层M2分别电性连接至多个像素单元,第三金属层M3设置于第一基板101中的周边区BA,并电性连接至第二金属层M2,第二金属层M2以及第三金属层M3实现控制电路IC与像素单元之间的控制信号及数据的传输。
再结合图1B、图1C以及图1D所示,第一基板101上还设置有第一平坦层PL,第一平坦层PL覆盖第二金属层M2,且第三金属层M3设置于第一平坦层PL。换言之,第二金属层M2设置于第一基板101与第一平坦层PL之间,而第一平坦层PL则设置于第二金属层M2与第三金属层M3之间。具体的,如图1B所示,第一平坦层PL具有多个支撑垫群组BG,相邻的两支撑垫群组BG之间形成有开口区SL,且每一支撑垫群组BG具有多个支撑垫BP,每一支撑垫群组BG中支撑垫BP的数量根据开口区SL的宽度设置,本发明并不以此为限。需要说明的是,第三金属层M3的位置对应于开口区SL,即仅在第一平坦层PL的开口区SL中设置第三金属层M3。如图1C以及图1D所示,第二基板102上设置有遮光层BM,于遮光层BM上设置有第一色阻层103以及第二色阻层104。本实施例中,于显示区AA相对应的区域中,第二色阻层104与第一色阻层103相邻设置,而于第三金属层M3相对应的区域中,第二 色阻层104与第一色阻层103层叠设置,即第二色阻层104设置于第一色阻层103上,如图1B所示。同时,请同时参阅图1B、图1C与图1D,第二基板102上还设置有第二平坦层OC,第二平坦层覆盖第一色阻层103以及第二色阻层104。于本实施例中,于支撑垫BP相对应的位置,在第二平坦层OC上设置有第一支撑结构PS1,如图1B所示;于第三金属层M3相对应的位置,在第二平坦层OC上设置有第二支撑结构PS2,如图1C所示。
于本实施例中,第一支撑结构PS1或第二支撑结构PS2于第二基板102上的投影形状为圆形,为更好的起到支撑作用,与第二支撑结构PS2相对应的第一色阻层103以及第二色阻层104于第二基板102上的投影形状为圆形或方形。当然,第一支撑结构PS1、第二支撑结构PS2、第一色阻层103以及第二色阻层104于第二基板102上的投影形状也可为其他形状,本发明并不以此为限。由此,通过在第三金属层M3相对应位置处层叠设置第一色阻层103以及第二色阻层104,使得可以避免显示面板不同区域高度落差的出现。
继续如图1A、图1B所示,沿显示装置100的中央区域CA分别向左右两侧延伸,第一平坦层PL中的多个开口区SL可以分为第一开口区SL1、第二开口区SL2以及第三开口区SL3(图中未示出)。其中,第一开口区SL1具有第一宽度W1,第二开口区SL2具有第二宽度W2,第三开口区具有第三宽度W3。于本实施例中,第一宽度W1、第二宽度W2以及第三宽度W3设置为相同,且第一宽度W1、第二宽度W2或第三宽度W3均小于等于100μm。
继续如图1C、图1D所示,第一色阻层103具有第一厚度T1,第二色阻层104具有第二厚度T2,支撑垫BP具有第三厚度T3,第三金属层M3具有第四厚度。于本实例中,为更好的实现本发明的目的,于显示装置100的周边区BA中,第一色阻层103的第一厚度T1大于第二色阻层104的第二厚度T2,且第二厚度T2应与第三厚度T3与第四厚度T4之间的差相同。其中,第一色阻层103与第二色阻层104既可以采用相同的膜层制成,也可以采用不同的膜层制成,本发明并不以此为限。由此,第二色阻层104可以抵消支撑垫BP与第三金属层M3之间厚度不同导致的显示面板不同区域的高度落差。
需要说明的是,图1B仅示例性的示出显示装置100中第一平坦层PL、第一色阻层103以及第二色阻层104的结构,对其他膜层的描述可参见图1C、图1D所示。
图2本发明另一实施例显示装置的结构示意图。如图2所示,与图1A-图1D所示实施例不同之处在于,于本实施例中,显示装置100的中央区域CA分别向左右两侧延伸,第一宽度W1、第二宽度W2以及第三宽度W3呈递进式增长方式设置,即第一宽度W1小于第二宽度W2,第二宽度W2小于第三宽度W3,但需要满足第一宽度W1、第二宽度W2以及第三宽度W3均小于等于100μm。图1B与图2仅绘示从中央区域CA往单一侧边(如左侧)延伸的结构示意图。
图3A本发明又一实施例显示装置的结构示意图,图3B是图3A中区域Q1的剖视示意图,图3C是图3A中区域Q2的剖视示意图。如图3A所示,显示装置100包括第一基板101、第二基板102,第一基板101与第二基板102相对设置。于本实施例中,第一基板101具有相邻的显示区AA以及周边区BA,显示区AA中设置有多个像素单元(图中未示出),多个像素单元呈阵列布置,沿着第一方向(例如X方向)排成多列,沿着第二方向(例如Y方向)排成多行,且每一像素单元中均形成有至少一薄膜晶体管(图中未示出)。第一基板上101上设置有控制电路IC,第一基板101上设置有第一布线结构105以及第二布线结构106。第一布线结构105及第二布线结构106耦接至控制电路IC,并分别电性连接至多个像素单元,控制电路IC通过第一布线结构105以及第二布线结构106实现与像素单元之间控制信号及数据的传输。如图3B、图3C所示,第一布线结构105由第二金属层M2以及第三金属层M3层叠设置所构成,第二布线结构106由第二金属层M2所构成。
与图1A-图1D所示实施例相同,结合图1B所示,于本实例中,显示装置100的第一基板101上同样设置有第一平坦层PL,第一平坦层PL覆盖第二金属层M2,且第三金属层M3设置于第一平坦层PL。换言之,第二金属层M2设置于第一基板101与第一平坦层PL之间,而第一平坦层PL则设置于第二金属层M2与第三金属层M3之间。第一平坦层PL具有多个支撑垫群组BG,相邻的两支撑垫群组BG之间形成有开口区SL,且每一支撑垫群组BG具有多个支撑垫BP,每一支撑垫群组BG中支撑垫BP的数量根据开口区SL的宽度设置,本发明并不以此为限。于本实施例中,第一布线结构105与开口区SL的位置相对应。
如图3B、图3C所示,本实施例中,第二基板102上分别设置有第一间隔 结构107舆第二间隔结构108,其中,第一间隔结构107与第一布线结构105位置相对应,而第二间隔结构108则与第二布线结构106位置相对应。具体的,如图3B所示,第一间隔结构107包括层叠设置的第一色阻层103、第二色阻层104以及第一支撑结构PS1,第二间隔结构108包括层叠设置的第一色阻层103以及第二支撑结构PS2。同时,第二基板102上还设置有第二平坦层OC,第二平坦层覆盖第一色阻层103以及第二色阻层104。于本实施例中,第一支撑结构PS1或第二支撑结构PS2于第二基板102上的投影形状为圆形,为更好的起到支撑作用,与第二支撑结构PS2相对应的第一色阻层103以及第二色阻层104于第二基板102上的投影形状为圆形或方形。当然,第一支撑结构PS1、第二支撑结构PS2、第一色阻层103以及第二色阻层104于第二基板102上的投影形状也可为其他形状,本发明并不以此为限。由此,通过在第一布线结构105相对应位置处层叠设置第一色阻层103以及第二色阻层104,使得可以避免显示面板不同区域高度落差的出现。
与图1A-图1D或图2所示实施例相同,本实例中,沿显示装置100的中央区域CA分别向左右两侧延伸,第一平坦层PL中的多个开口区SL可以分为第一开口区SL1、第二开口区SL2以及第三开口区SL3。其中,第一开口区SL1具有第一宽度W1,第二开口区SL2具有第二宽度W2,第三开口区具有第三宽度W3。于本实施例中,第一宽度W1、第二宽度W2以及第三宽度W3可设置为相同,也可设置为第一宽度W1小于第二宽度W2,第二宽度W2小于第三宽度W3,但需要满足第一宽度W1、第二宽度W2以及第三宽度W3均小于等于100μm。
与图1A-图1D所示实施例相同,本实例中,第一色阻层103具有第一厚度T1,第二色阻层104具有第二厚度T2,支撑垫BP具有第三厚度T3,第三金属层M3具有第四厚度。为更好的实现本发明的目的,于显示装置100的周边区BA中,第一色阻层103的第一厚度T1大于第二色阻层104的第二厚度T2,且第二厚度T2应与第三厚度T3与第四厚度T4之间的差相同。其中,第一色阻层103与第二色阻层104既可以采用相同的膜层制成,也可以采用不同的膜层制成,本发明并不以此为限。由此,第二色阻层104可以抵消支撑垫BP与第三金属层M3之间厚度不同导致的显示面板不同区域的高度落差。
综上,依照本发明的实施例,由于在与第三金属层对应的位置,通过在支 撑结构下垫设第二色阻层的方式,可以抵消支撑垫与第三金属层之间厚度不同导致的显示面板不同区域的高度落差,更好地避免显示面板不同区域高度落差的出现,减少显示不均现象的发生,提高产品的显示效果。
当然,本发明还可有其它多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
