然而,在栅线和数据线的交叠部位,由于数据线和栅线上的电荷的释放经常会发生静电(Electro-Static discharge,简称ESD)击穿,使得数据线和栅线短路,从而导致显示不良。

本发明实施例中的静电释放组件可以对不同电压的静电进行相应的释放与中和,因而,提高了静电释放组件的抗ESD的能力。在此基础上,静电电流可以依次通过第一电极、半导体层和第二电极进行释放与中和,当然也可以是,依次通过第二电极、半导体层和第一电极进行释放和中和,因而该静电释放组件还可以进行对等双向流通。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例提供一种静电释放组件,如图1(a)和图1(b)所示,包括设置在衬底基板10上的半导体层20、绝缘层30、第一辅助电极401、第一电极50和第二电极60;第一电极50和第二电极60相对设置。其中,第一电极50和第二电极60与半导体层20均接触;第一电极50或第二电极60与第一辅助电极401接触;第一辅助电极401、半导体层20、以及第一电极50和第二电极60之间设置有绝缘层30隔离。
需要说明的是,第一,本发明实施例中的静电释放组件可以应用在任意的电子设备中,用于进行静电释放。例如,显示器的阵列基板、集成电路等。
本发明实施例的静电释放组件进行静电释放的原理为:由于第一电极50和第二电极60与半导体层20均接触,因此,当该静电释放组件用于静电释放时,第一电极50、半导体层20和第二电极60之间便可形成一个导电通道,而半导体层20具有特殊的性能,随着线路静电电压于第一电极50和第一辅助电极401上的增加,第一辅助电极401对半导体层20电场强度也相对提高,致使半导体层20产生反相电荷形成通道后利于静电电流流过,相应的,第二电极60与第二辅助电极402对于半导体层20也是有着同样的动作,此时,半导体层20相当于是个小电阻,所述导电通道可以对电荷进行静电释放与中和。进一步地,当静电电压越高时,半导体层20通道相当于低电阻,从而对高静电电压进行大电流进行静电释放与中和。
具体的,当上述静电释放组件应用于阵列基板时,可用于解决数据线或栅线产生的静电。示例的,数据线与静电释放组件中的第一电极50相连,公共电极线与静电释放组件中的第二电极60相连,当数据线上产生的静电电压较小(例如<50V)时,数据线上的电流可以通过第一电极50、半导体层20流向公共电极线,从而使得数据线上的小电流逐渐被释放与中和;随着数据线上产生的静电电压逐渐增大(例如50V~300V),半导体层20在高电压的作用下,电阻减小,因而数据线上产生的静电电流可以通过第一电极50、半导体层20快速流向公共电极线,从而使得数据线上的大电流被释放与中和;当数据线上产生的静电的电压较大(300V~1KV)时,一方面,半导体层20在高电压的作用下,电阻减小,因而数据线上的静电电流可以通过第一电极50、半导体层20快速流向公共电极线,从而使得数据线上的电流被快速释放和中和,此外,由于第一电极50和第二电极60相对设置,当数据线上的电压较大时,第一电极50和第二电极60也可以对数据线上的电流进行释放与中和;另一方面,由于第一电极50或第二电极60还与第一辅助电极401相连,因而数据线上的电流还可以通过第一辅助电极401进行释放与中和。
第二,对于静电释放组件中半导体层20、第一辅助电极40、第一电极50和第二电极60具体设置位置不进行限定,只要第一电极50和第二电极60与半导体层20均接触即可。例如可以是如图1(a)或图1(c)所示的,在衬底基板10上依次形成半导体层20、绝缘层30、第一辅助电极401及第一电极50和第二电极60;当然也可以是,如图1(b)所示的,在衬底基板10上依次形成第一辅助电极401、绝缘层30、半导体层20及第一电极50和第二电极60。
第三,第一辅助电极401可以通过绝缘层30上的过孔与第一电极50接触或者与第二电极60接触。
此处,第一辅助电极401设置在第一电极50、第二电极60与半导体层20之间,由于第一辅助电极401与第一电极50或第二电极60接触,而第一电极50和第二电极60与半导体层20接触,即,相当于第一辅助电极401与半导体层40接触,当所述导电通道中有电流经过时,由于第一辅助电极401与半导体层20的距离较近,因而第一辅助电极401可以使半导体层20中的导电通道快速打开,以进行静电释放与中和。
第四,对于半导体层20的材料不进行限定,例如可以是非晶硅、多晶硅等。
第五,对于绝缘层30的材料不进行限定,例如可以为氮化硅、氧化硅或氮氧化硅等绝缘材料。
第六,对于第一辅助电极401、第一电极50和第二电极60的材料,只要能导电即可,例如可以为铝、钨、铬、钼或其它金属、金属化合物以及合金。第一辅助电极401、第一电极50和第二电极60的材料可以相同,也可以不同。
本发明实施例提供一种静电释放组件,由于第一电极50和第二电极60与半导体层20均接触,因而当该静电释放组件用于静电释放时,第一电极50、半导体层20及第二电极60便可形成一个导电通道。其中,由于半导体层20的电阻随着电压的增加,电阻减小,因而该静电释放组件既可以进行被动静电释放,即,当静电电压较小时,静电释放组件可以对静电电压进行小电流释放与中和,又可以进行主动静电释放,即,随着静电电压的增大,静电释放组件对大电流进行释放与中和的能力增加。进一步地,由于第一辅助电极401与第一电极50或第二电极60接触,因而当静电释放组件中经过的电流较大时,第一辅助电极401还可以对大电流进行释放与中和,从而使得静电释放组件可以快速释放和中和静电。本发明实施例中的静电释放组件可以对不同电压的静电进行相应的释放与中和,因而,提高了静电释放组件的抗ESD的能力。在此基础上,静电电流可以依次通过第一电极50、半导体层20和第二电极60进行释放与中和,当然也可以是,依次通过第二电极60、半导体层20和第一电极50进行释放和中和,因而该静电释放组件还可以进行对等双向流通。
优选的,如图1(c)和图1(d)所示,上述静电释放组件还包括与第一辅助电极401相对且绝缘的第二辅助电极402。
其中,第二辅助电极402的材料和第一辅助电极401的材料可以相同,也可以不同。第二辅助电极402的材料例如可以为铝、钨、铬、钼或其它金属、金属化合物以及合金。第二辅助电极402可以通过绝缘层30上的过孔与第二电极60接触。
本发明实施例中,当静电释放组件中经过的电流较大时,第一辅助电极401和第二辅助电极402都可以对大电流进行瞬间释放与中和,从而使得静电释放组件可以快速释放与中和静电,提高了静电释放组件的大电流静电释放与中和的能力。
优选的,如图2(a)、图2(b)、图2(c)或图3所示,第一辅助电极401和第二辅助电极402分别包括锯齿状的尖端;和/或;第一电极50和第二电极60分别包括锯齿状的尖端。优选的,第一辅助电极401和所述第二辅助电极402同层设置且第一辅助电极401和所述第二辅助电极402的相对侧分别包括锯齿状的尖端和/或,第一电极50和所述第二电极60同层设置,且第一电极50和所述第二电极60的相对侧分别包括锯齿状的尖端。
其中,可以是如图2(a)所示的,第一辅助电极401和第二辅助电极402的相对侧分别包括锯齿状的尖端,第一电极50和第二电极60的相对侧不包括锯齿状的尖端;或者,如图2(b)所示的,第一辅助电极401和第二辅助电极402的相对侧不包括锯齿状的尖端,第一电极50和第二电极60的相对侧分别包括锯齿状的尖端;或者,如图2(c)所示的,第一辅助电极401和第二辅助电极402的相对侧分别包括锯齿状的尖端,第一电极50和第二电极60的相对侧也分别包括锯齿状的尖端。
此处,需要说明的是,第一辅助电极401和第二辅助电极402的相对侧可以是如图2(a)和图2(c)所示的全部设置成锯齿状的尖端,也可以是如图3所示的,部分设置成锯齿装的尖端。第一电极50和第二电极60的相对侧可以是如图2(b)所示的全部设置成锯齿状的尖端,也可以是如图3所示的部分设置成锯齿装的尖端。
对于第一辅助电极401、第二辅助电极402、第一电极50和第二电极60包括的锯齿状的尖端的个数,可根据静电释放组件中用于释放的最大电压进行设置。锯齿状的尖端的个数越多,越能够快速地释放高电压的静电。
本发明实施例中,第一辅助电极401和第二辅助电极402同层设置,且第一辅助电极401和第二辅助电极402的相对侧分别设置有锯齿状的尖端,和/或,第一电极50和第二电极60同层设置,且第一电极50和第二电极60的相对侧分别设置有锯齿状的尖端,由于尖端状的外形有利于高电压瞬间放电,因而当静电释放组件需要对高电压的静电进行释放与中和时,可以通过第一辅助电极401、第二辅助电极402,和/或,第一电极50和第二电极60的相对侧设置的锯齿状的尖端瞬间进行放电。
在实际生产过程中,由于第一辅助电极401和第二辅助电极402的距离较近,若将第一辅助电极401和第二辅助电极402的相对侧,全部设置成锯齿状的尖端,则第一辅助电极401的锯齿状的尖端很容易和第二辅助电极402上锯齿状的尖端接触,因而会导致第一辅助电极401和第二辅助电极402连接在一起,从而使得上述静电释放组件在高电压时,不能有效达到瞬间释放与中和高电压静电目的;同理,若将第一电极50和第二电极60的相对侧,全部设置成锯齿状的尖端,则第一电极50的锯齿状的尖端很容易和第二电极60的锯齿状的尖端接触,因而会导致第一电极50和第二电极60连接在一起,从而使得上述静电释放组件在高电压时,不能有效达到瞬间释放和中和高电压的静电目的。
基于上述,本发明实施例进一步优选的,如图3所示,第一辅助电极401和第二辅助电极402上的尖端相互错开;和/或,第一电极50上的尖端与第二电极60上的尖端相互错开,如此可以更有利于尖端放电。
此处需要说明的是,第一电极50上的尖端与第二电极60上的尖端相互错开是指第一电极50上的尖端整体和第二电极60上的尖端整体相互错开;第一辅助电极401和第二辅助电极402上的尖端相互错开是指第一辅助电极401上的尖端整体与第一辅助电极401上的尖端整体相互错开。
基于上述,由于多晶硅具有高的迁移率、响应速度快等优点且多晶硅可以在低温下制作,因而优选的,如图1(a)所示,半导体层20为多晶硅层201,在此基础上,绝缘层30包括第一子绝缘层301和第二子绝缘层302,第一子绝缘层301设置在多晶硅层201与第一辅助电极401之间,第二子绝缘层302设置在第一辅助电极401与第一电极50和第二电极60之间。
其中,多晶硅层201的制作过程例如可以是在衬底基板10上沉积一层非晶硅(a-Si),采用ELA(Excimer Laser Annealing,准分子激光退火)或SPC(Solid PhaseCrystallization,固相结晶化)的方式进行结晶,从而形成多晶硅层201。当然,也可以直接形成多晶硅层201。
第二子绝缘层302的材料可以和第一子绝缘层301的材料相同,也可以不同。
本发明实施例中,通过将半导体层20设置为多晶硅层201,由于多晶硅的迁移率高、响应速度快,因而本发明实施例中的静电释放组件能够快速释放静电。
由于光照会影响半导体层20的漏电流,因而,为了避免光照对静电释放组件的影响,进一步优选的,如图4所示,上述静电释放组件还包括设置在衬底基板10上的靠近半导体层20一侧的遮光层70和隔离层80;遮光层70在衬底基板10上的投影完全覆盖半导体层20在衬底基板10上的投影。
其中,对于遮光层70的材料,只要能够遮光即可,例如可以为油墨、树脂聚合物、金属等。隔离层80的材料可以为氮化硅、氧化硅或氮氧化硅等绝缘材料。
本发明实施例中,通过设置遮光层70,且使遮光层70在衬底基板10上的投影完全覆盖半导体层20在衬底基板10上的投影,这样便可以避免光照对半导体层20的影响,进而避免了对静电释放组件的影响。
本发明实施例提供了一种阵列基板,包括显示区和非显示区,非显示区包括多个上述的静电释放组件。
其中,显示区包括栅线、数据线,以及由栅线和数据线交叉限定的子像素,每个子像素包括薄膜晶体管,薄膜晶体管包括栅极、绝缘层、半导体层、源极和漏极。当该阵列基板为液晶显示器的(Liquid Crystal Display,简称LCD)阵列基板时,每个子像素还包括像素电极,进一步的还可以包括公共电极、公共电极线。当该阵列基板为有机电致发光二管(Organic Light-Emitting Diode,简称OLED)显示器的阵列基板时,每个子像素还包括阳极、有机材料功能层以及阴极。
需要说明的是,对于静电释放组件的个数,可根据阵列基板中需要进行静电释放的数据线和栅极的条数进行合理设置。
本发明实施例提供一种阵列基板,在非显示区设置多个静电释放组件,由于每个静电释放组件都可以对与其相连的栅线和数据线上的低电压静电、中电压静电或高电压静电分别进行相对应的释放与中和,因而提高了阵列基板的抗ESD的能力,防止阵列基板受到破坏。
优选的,显示区包括栅线、数据线以及公共电极线,其中,栅线或数据线与静电释放组件中的第一电极50相连;公共电极线与静电释放组件中的第二电极60栅极相连。
或者,栅线与静电释放组件中的第一电极50相连;数据线与静电释放组件中的第二电极60相连。
这样,可释放与中和栅极和/或数据线上的静电电压。
需要说明的是,本发明实施中栅线或数据线与静电释放组件中的第一电极50相连,可以是仅栅线与静电释放组件中的第一电极50相连,用于释放栅线上的静电电压;或者是,仅数据线与静电释放组件中的第一电极50相连,用于释放数据线上的静电电压;当然也可以是,栅线和数据线均与不同静电释放组件中的第一电极50相连,此时栅线和数据线与不同的静电释放组件相连,用于释放栅线和数据线上的静电电压。
本发明实施例中,若第一辅助电极401与第一电极50接触,由于第一电极50与半导体层20接触,因而无论是栅线或者数据线或者还是公共电极线,其与第一电极50相连,即相当于也和与第一电极50接触的第一辅助电极401相连,如此在大电流放电时,栅线或者数据线或者公共电极上的电荷可以既通过第一电极放电也可以通过第一辅助电极放电;同理,若第二辅助电极402与第二电极60接触,由于第二电极60与半导体层20接触,因而无论是栅线或者数据线或者还是公共电极线,其与第二电极60相连,即相当于也和与第二电极60接触的第二辅助电极402相连。
此处,需要说明的是,栅线或数据线只能和第一电极50或与第一电极50接触的第一辅助电极401中的一个相连,若一条栅线与第一电极50相连,另一条栅线和该静电释放组件中与第一电极50接触的第一辅助电极401相连,则会导致这两条栅线短路;或者,一条栅线与第一电极50相连,一条数据线和该静电释放组件中与第一电极50接触的第一辅助电极401相连,则会导致栅线和数据线短路。可以理解的是,各条公共电极线通常接恒定电位,如接地或者接零电位,所以在一条公共电极线接第一电极50的同时,另一条公共电极线可以接第一辅助电极401;第二电极60和第一辅助电极402的连接与第一电极50和第二辅助电极402类似,再此不再赘述。
当需要对阵列基板中的栅线和数据线上的静电均进行释放与中和时,可以将栅线和数据线与不同的静释放组件中的第一电极50相连,公共电极线与静电释放组件中的第二电极60相连。此时,阵列基板中的静电释放组件的个数至少大于等于栅线条数和数据线条数之和。或者,可以将栅线与静电释放组件中的第二电极60相连,数据线与静电释放组件中的第一电极50相连,此时,阵列基板中的静电释放组件的个数至少应大于栅线和数据线中条数较多的个数。此处,需要说明的是,若数据线与栅线的条数不相同,数据线与栅线通过静电释放组件一一对应连接后,剩余的栅线或数据线可以通过公共电极线释放剩余的栅线或数据线上的电压。
优选的,静电释放组件中的第一电极50和第二电极60与栅线同层设置;或者,静电释放组件中的第一电极50和第二电极60与数据线同层设置;或者,针对例如液晶显示器件而言,显示区还包括像素电极和公共电极,静电释放组件中的第一电极50和第二电极60与像素电极或公共电极同层设置。针对例如有机电致发光显示器件而言,静电释放组件中的第一电极50和第二电极60也可与阳极同层设置。
即:通过同一次构图工艺形成静电释放组件中的第一电极50和第二电极60以及栅线,或者通过同一次构图工艺形成静电释放组件中的第一电极50和第二电极60以及数据线,或者通过同一次构图工艺形成静电释放组件中的第一电极50和第二电极60以及像素电极或公共电极。
本发明实施例中,由于栅线与静电释放组件中的第一电极50和第二电极60同层设置,因而可以利用现有工艺,在制作阵列基板上的栅线的同时制作静电释放组件中的第一电极50和第二电极60;或者,数据线与静电释放组件中的第一电极50和第二电极60同层设置,在制作阵列基板上的数据线的同时制作静电释放组件中的第一电极50和第二电极60;或者,将静电释放组件中的第一电极50和第二电极60与像素电极或公共电极同层设置,这样便可以利用现有工艺在制作像素电极或公共电极的同时制作第一电极50和第二电极60,因而无需增加新的膜层和制作工艺,简化了静电释放组件的制作工艺。
优选的,上述静电释放组件中的第一辅助电极401和第二辅助电极402与栅线或数据线同层设置。即,通过同一次构图工艺形成静电释放组件中的第一辅助电极401和第二辅助电极402与栅线,或者通过同一次构图工艺形成静电释放组件中的第一辅助电极401和第二辅助电极402与数据线。
本发明实施例,利用现有工艺在制作阵列基板上的栅线或数据线的同时可以制作静电释放组件中的第一辅助电极401和第二辅助电极402,无需增加新的膜层和制作工艺,因而简化了静电释放组件的制作工艺。
本发明实施例提供一种阵列基板的制备方法,包括:在显示区形成显示结构,在非显示区形成上述的静电释放组件;静电释放组件与显示结构同步形成。
其中,显示结构可以包括栅极、栅线、公共电极线、源极、漏极、数据线、像素电极,进一步的还可以包括公共电极等。此处,对于静电释放组件中某一结构例如第一电极50与显示结构中的何种结构同步形成不进行限定。
本发明实施例中,由于静电释放组件和显示结构同步形成,因而可以在形成显示结构的同时形成静电释放组件,无需增加额外工艺,简化了阵列基板的制作工艺。
可选的,第一电极50和第二电极60与栅极、栅线通过同一次构图工艺形成;或者,第一电极50和第二电极60与源极、漏极及数据线通过同一次构图工艺形成;或者,第一电极50和第二电极60与像素电极通过同一次构图工艺形成;或者,第一电极50和第二电极60与公共电极通过同一次构图工艺形成。
本发明实施例,利用现有工艺在形成源极、漏极及数据线的同时形成第一电极50和第二电极60;或者,在形成像素电极的同时形成第一电极50和第二电极60;或者,在形成栅极、栅线的同时形成第一电极50和第二电极60;或者,在形成公共电极的同时形成第一电极50和第二电极60,这样便无需增加额外工艺,简化了阵列基板的制作工艺。
可选的,第一辅助电极401和第二辅助电极402与栅极、栅线通过同一次构图工艺形成;或者,第一辅助电极401和第二辅助电极402与源极、漏极、数据线通过同一次构图工艺形成。
其中,由于第一辅助电极401、第二辅助电极402与第一电极50、第二电极60是在不同层形成,因而第一辅助电极401、第二辅助电极402和第一电极50、第二电极60并不能与栅极、栅线同时形成,或与源极、漏极、数据线同时形成。
本发明实施例中,由于利用现有工艺在形成栅极、栅线的同时形成第一辅助电极401和第二辅助电极402;或者,在形成源极、漏极、数据线的同时形成第一辅助电极401和第二辅助电极402,这样便无需增加额外工艺,简化了阵列基板的制作工艺。
本发明实施例还提供了一种显示装置,包括上述的阵列基板。
其中,显示装置可以为LCD的显示装置,也可以为OLED的显示装置。
其中,当阵列基板为LCD的阵列基板时,显示装置还包括与阵列基板对盒的对盒基板,彩色膜片可以设置在阵列基板上,也可以设置在对盒基板上。
本发明实施例提供一种显示装置,由于该显示装置包括上述的静电释放组件,因而可以对数据线和栅线上产生的静电进行释放与中和,从而防止了数据线和栅线上的静电使显示装置受到破坏,提高了显示装置的抗ESD的能力。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。
