具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例的附图,对本发明实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本发明的一部分实施例,而不是全部的实施例。基于所描述的本发明的实施例,本领域普通技术人员在无需创造性劳动的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。
如图1所示,一种触控面板中集成有相互绝缘的行列交叉的触控感应电极(简称为Rx)与触控驱动电极(简称为Tx),其触控原理是利用人体自身的导电特性。当手指触摸屏幕时,通过检测触控面板中触控感应电极Rx与触控驱动电极Tx交叉处形成的耦合电容(Cm)的数值变化,获取该触摸点的触摸位置信息。
然而,由于OLED触控产品实现触控的原理是感应耦合电容(Cm)的变化,所以绝缘性的物体触控到屏幕时不会改变耦合电容(Cm)的大小,也就无法通过检测耦合电容(Cm)变化来获取该触摸点的位置信息了。因此,绝缘体无法实现触控功能,在一定程度上限制了OLED触控产品的易用性。例如,用户如果在冬天使用具有触控功能的智能产品时,由于普通手套不导电,无法操作电容式触控产品。所以,用户必须脱卸掉手套才能使用触控手机,造成用户使用不便。
如图2所示,本发明实施例提供一种OLED显示基板10,该OLED显示基板10具有显示区域(图中及下文中均标记为AA)。显示区域AA包括多个间隔分布的第一子区A1、以及位于第一子区A1之间的第二子区A2;该OLED显示基板10包括:位于第一子区A1的至少一个OLED发光单元11;位于第二子区A2的多个光学感应单元12、以及与光学感应单元12相连且交叉设置的第一驱动电极线13、第一传输电极线14。光学感应单元12包括光敏传感器件121,光敏传感器件121用于根据感应到的触摸点的光线强度变化生成电信号;第一驱动电极线13与第一传输电极线14用于提供电信 号以确定触摸点的位置。
需要说明的是,第一、本发明实施例提供的上述光敏传感器件121,将感应到的触摸点的光线强度变化生成相应的电信号,第一驱动电极线13与第一传输电极线14根据该电信号来获取触摸点的位置信息。由此可知,不论是导体还是绝缘体,只要物体不透明,可对触摸点产生光线强度的变化,即可实现对上述OLED显示基板10的触控。因此,用户可以任意方式,例如导体触摸方式(手指或触控笔的触摸)或绝缘体触摸方式(穿戴手套或通过普通书写笔的触摸)对上述的OLED显示基板10进行操控,从而为用户提供了更好的操作体验。
这里,光敏传感器件121中实现光电转化的结构例如可以采用对光线强度变化非常敏感的P-Si(P型硅半导体)光电半导体材料构成,其对光线强度变化的敏感程度可以通过对掺杂浓度的调节来控制。
例如,如图3所示,当不透明物体(如图中所示的手指)触摸到OLED显示基板10的显示区域AA时,遮挡住了透射进OLED显示基板10中的光线,使得不透明物体与OLED显示基板10相接触的区域(如图中阴影部分所示)光线强度小于周围区域,即发生了光线强度的变化。光敏传感器件121感应到光线强度的变化后,即将这一光线变化转化为一定的电信号,第一驱动电极线13与第一传输电极线14根据上述的电信号来确定触摸点的位置。
第一驱动电极线13与第一传输电极线14根据上述的电信号来确定触摸点的位置可以通过但不限于以下方式实现:
第一驱动电极线13通过向光敏传感器件121输入相应的扫描信号将光敏传感器件121开启,当OLED显示基板10中某一处的光敏传感器件121感应到光线强度发生变化并产生相应的电信号后,该电信号会通过第一传输电极线14传输至相应的触控IC(Integrated Circuit,集成电路)中;此时,由于光敏传感器件121内部产生了上述的电信号,该电信号使得与该光敏传感器件121相连的第一驱动电极线13中的扫描信号发生变化,第一驱动电极线13将上述的扫描信号发生变化的信息也传输至触控IC中。这样一来,与触控IC相连的第一驱动电极线13,相当于用于定位触摸点的二维坐标系中的一轴;而与触控IC相连的第一传输电极线14,则相当于该坐标系中相交的另一轴,由此来确定触摸点的具体位置信息。
为了保证上述OLED显示基板10具有较高的触控精度,第二子区A2应较为均匀对称地将第一子区A1间隔开来,并且使光学感应单元12均匀地分布在上述第二子区A2中,以使OLED显示基板10可以较为全面地获取发生在上述显示区域AA中的触摸点,从而准确获取相应触摸点的位置信息。
由于OLED发光单元11具有自发光的特性,OLED发光单元11与光学感应单元12分别位于第一子区A1与第二子区A2中,即上述的两个光学单元相互不重叠。因此,光学感应单元12中的光敏传感器件121感应到的光线的变化只会来自于不透明的物体的触摸,而不会受到OLED发光单元11自身发光的影响,从而保证了上述的OLED显示基板10获取触摸点位置信息的精准性。
基于此,通过本发明实施例提供的上述OLED显示基板10,用户可以任意方式,例如导体触摸方式(手指或触控笔的触摸)或绝缘体触摸方式(穿戴手套或通过普通书写笔的触摸)对上述的OLED显示基板10进行操控,从而为用户提供了更好的操作体验。
此外,集成有显示与触控的多种功能OLED显示基板10能耗较大。并且,在很多情况下,用户是在户外或室内光线强度较大的灯光等环境中使用上述显示产品的。由于环境光的影响,用户需要将显示产品的屏幕亮度调高才能较为清楚地分辨显示的内容。这进一步增加了显示产品的能耗,导致显示产品电池续航能力较差。
为解决这个问题,进一步的,光学感应单元12还可以包括:可接收环境光以产生电荷载流子的太阳能电池器件122。该太阳能电池器件122可将产生的电能供给OLED显示基板10,从而为其提供实时供电。
上述的太阳能电池器件122例如可以为碲化镉/硫化镉等薄膜太阳能电池,或者为异质结构太阳能电池等。太阳能电池器件122只要具有上述的吸收环境光以产生电荷的功能即可,具体类型不作限定。
光敏传感器件121与太阳能电池器件122的工作可采用例如以下两种方式进行:
方式一中,在第二子区A2中,与光敏传感器件121相连的第一驱动电极线13、第一传输电极线14同时也与太阳能电池器件122相连,即光敏传感器件121与太阳能电池器件122共用驱动与传输线。
如图4A所示,在一个示例中,光学感应单元12还包括:与第一驱动电极线13、第一传输电极线14连接的上述太阳能电池器件122;与光敏传感器件121串联的第一开关管15;第一开关管15位于以第一驱动电极线13为总线的第一支路131上,且相对于光敏传感器件121更靠近第一驱动电极线13的信号输入端(图中及下文中均标记为13a);与太阳能电池器件122串联的第二开关管16;第二开关管16位于与第一支路131并联的第二支路132上,且相对于太阳能电池器件122更靠近第一驱动电极线13的信号输入端13a;第一驱动电极线13还用于驱动太阳能电池器件122开启;第一传输电极线14还用于输出太阳能电池器件122产生的电能;其中,第一开关管15与第二开关管16具有相反的开关特性。
需要说明的是,第一、图4A仅示意出上述各器件及相应电极线的可能的一种排列方式。各器件及相应电极线的排列可灵活设计,只要使得上述的各电极线实现相应的功能即可。
第二、由于第一开关管15与第二开关管16具有相反的开关特性,当向第一开关管15输入相应的电信号使其导通时,同样的电信号输入至第二开关管16则会使后者关闭。也就是说,在上述两个开关管中,其中一者开启,另一者则会关闭,从而使得相应的电信号只会通过第一开关管15与第二开关管16二者中的一者传输出。
在上述实施例中,第一开关管15位于以第一驱动电极线13为总线的第一支路131上,且相对于光敏传感器件121更靠近第一驱动电极线13的信号输入端13a;第二开关管16位于与第一支路131并联的第二支路132上,且相对于太阳能电池器件122更靠近第一驱动电极线13的信号输入端13a。因此,当光敏传感器件121工作时,太阳能电池器件122关闭;反之亦然。从而使得OLED显示基板10在不同的阶段具有不同的功能。
具有相反的开关特性的开关管可采用常规技术实现。例如,第一开关管15可以为P型TFT,即TFT(Thin Film Transistor,薄膜晶体管)中有源层的类型为P型半导体。P型TFT具有低电平开启、高电平关闭的特性;第二开关管16可以为N型TFT,即TFT中有源层的类型为N型半导体。N型TFT具有与P型TFT相反的特性,即高电平开启、低电平关闭。
在上述方式一的结构设计中,由于光敏传感器件121与太阳能电池器件 122共用第一驱动电极线13、第一传输电极线14,在OLED显示基板10的衬底基板上进行各种电极线排布的难度被降低,对衬底基板的利用率得到了提高,显示产品的制备成本也降低了。
在上述方式一的结构设计中,第二子区A2将第一子区A1相互之间间隔开来而可能影响OLED显示基板10的正常显示,为了减小该影响,在上述结构设计基础上,如图4A所示,第一子区A1呈矩阵排列;第一驱动电极线13位于相邻两行的第一子区A1之间,第一传输电极线14位于相邻两列的第一子区A1之间。
相互间隔开的第一子区A1呈矩阵排列,即,第一子区A1与相邻的任一第一子区A1在行方向与列方向上均具有间隔,通过将第一驱动电极线13设置在相邻两行的第一子区A1之间、第一传输电极线14设置在相邻两列的第一子区A1之间。上述结构设计可以带来两方面的技术效果。一方面,在第一子区A1行列之间的间隔区域布线设计简单;另一方面,由于第一驱动电极线13与第一传输电极线14交叉设置,分别位于第一子区A1的行、列间隔处,因此,第一驱动电极线13与第一传输电极线14之间为垂直交叉,二者相当于构成了一个正交型坐标系,可简化驱动IC根据获取的电信号确定触摸点位置信息的计算过程,降低软件设计难度。
在上述方式一的结构设计中,第一驱动电极线13与第一传输电极线14的设置位置可互换,即将第一传输电极线14设置在相邻两行的第一子区A1之间、第一驱动电极线13设置在相邻两列的第一子区A1之间,其效果同上,在此不再赘述。
方式二中,使光敏传感器件121与太阳能电池器件122具有各自的驱动与传输线。如下所述:
如图4B所示,一个示例中,OLED显示基板10还包括:位于第二子区的第二驱动电极线17、第二传输电极线18;其中,光学感应单元12还包括:与第二驱动电极线17、第二传输电极线18连接的太阳能电池器件122;第二驱动电极线17用于驱动太阳能电池器件122开启;第二传输电极线18用于输出太阳能电池器件122产生的电能。
需要说明的是,与上述方式一相比,方式二的结构设计通过设置上述的第二驱动电极线17、第二传输电极线18,可以实现光敏传感器件121与太阳 能电池器件122的独立工作,互不影响,即使得OLED显示基板10在实现触控操作的同时,还可以充分利用环境光来进行实时的充电,从而可更显著地提高产品的续航能力。
此外,由于光敏传感器件121与太阳能电池器件122相互独立工作,因此不需要设置额外的开关管,简化了电路设计,降低了OLED显示基板的制备工艺难度。
在上述方式二的结构设计中,第二子区A2将第一子区A1相互之间间隔开来而可能影响OLED显示基板10的正常显示,为了减小该影响,在上述结构设计基础上,如图4B所示,第一子区A1呈矩阵排列;第一驱动电极线13、第二驱动电极线17均位于相邻两行的第一子区A1之间;第一传输电极线14、第二传输电极线18均位于相邻两列的第一子区A1之间。
相互间隔开的第一子区A1呈矩阵排列,即,第一子区A1与相邻的任一第一子区A1在行方向与列方向上均具有间隔,通过将第一驱动电极线13设置在相邻两行的第一子区A1之间、第一传输电极线14设置在相邻两列的第一子区A1之间。上述结构设计可以带来两方面的技术效果。一方面,在第一子区A1行列之间的间隔区域布线设计简单;另一方面,由于第一驱动电极线13与第一传输电极线14交叉设置,分别位于第一子区A1的行、列间隔处,因此,第一驱动电极线13与第一传输电极线14之间为垂直交叉,二者相当于构成了一个正交型坐标系,可简化驱动IC根据获取的电信号确定触摸点位置信息的计算过程,降低软件设计难度;另一方面,由于第一驱动电极线13、第二驱动电极线17分别是使光敏传感器件121、太阳能电池器件122开启的,需要向其分别输入驱动的电信号。因此,将这两个电极线均放置在相邻两行的第一子区A1之间,可以在行方向上同时向两个驱动电极线输入相应的电信号,不需要设置额外的传输线;同样的,第一传输电极线14、第二传输电极线18分别是将光敏传感器件121、太阳能电池器件122产生的电信号输出的,需要连接相应的IC来接收电信号。因此,将这两个电极线均放置在相邻两列的第一子区A1之间,可以在列方向上同时接收两个传输电极线传输出的电信号,不需要设置额外的传输线,电路设计得到简化。
在上述方式二的结构设计中,上述驱动线与传输线的相对位置可互换,效果同上,在此不再赘述。
需要说明的是,上述两种方式具有不同的优点,可根据OLED显示基板10的尺寸参数、制备时的工艺参数灵活选择,具体不作限制。
进一步,如图5所示,OLED发光单元11包括:在衬底基板100上依次设置的第一电极111、有机材料功能层112以及第二电极113;光敏传感器件121包括:在衬底基板100上依次设置的第三电极1211、第一光电转换层1212以及第四电极1213;其中,第一电极111与第二电极113互为阴极与阳极;第三电极1211与第四电极1213互为阴极与阳极;第三电极1211、第一光电转换层1212、以及第四电极1213分别与第一电极111、有机材料功能层112、以及第二电极113同层设置。
需要说明的是,第一、有机材料功能层112通常由分别靠近阳极、阴极的空穴传输层、电子传输层以及位于二者之间的发光层构成,具体结构可沿用常规技术实现。第二、所谓“同层设置”是针对至少两种图形而言的,是指将至少两种结构的图形设置在同一层薄膜上的结构。
第三电极1211与第一电极111同层设置,是指二者可以通过同一个构图工艺在采用同种材料制成的一层薄膜上形成,以简化构图工艺;同理,第四电极1213与第二电极113同层设置,是指二者可以通过同一个构图工艺在采用同种材料制成的一层薄膜上形成,以简化构图工艺;第一光电转换层1212的作用是将光线强度的变化转化成电信号,有机材料功能层112的作用是实现电致发光,由于二者作用不同,因此第一光电转换层1212与有机材料功能层112同层设置,是指二者可以通过同一个制备工艺,如均采用溶液法或蒸镀法制得,以提高在衬底基板100上制备OLED发光单元11、光敏传感器件121等多种光学单元的生产效率。
进一步的,在上述各结构层同层设置的基础上,第三电极1211、第一光电转换层1212、以及第四电极1213分别与第一电极111、有机材料功能层112、以及第二电极113厚度相同,这样一来,相比于仅有OLED发光单元的OLED显示基板,本发明实施例提供的上述OLED显示基板10在集成有上述的显示、触控多种功能的基础上,并没有增加OLED显示基板10的整体厚度,从而使得该OLED显示基板10在具有导体、绝缘体触控功能的同时,仍然保持了整体轻薄化的结构设计。
进一步,如图5所示,太阳能电池器件122包括:在衬底基板100上依 次设置的第五电极1221、第二光电转换层1222、以及第六电极1223;其中,第五电极1221与第六电极1223互为阴极与阳极;第五电极1221、第二光电转换层1222、以及第六电极1223分别与第一电极111、有机材料功能层112、以及第二电极113同层设置。
这里,太阳能电池器件122中的各结构层与光敏传感器件121以及OLED发光单元11中的各结构层同层设置,可以将相应的结构层在同一个构图工艺或同一个制备工艺中形成,简化工艺过程。
进一步,第五电极1221、第二光电转换层1222、以及第六电极1223分别与第一电极111、有机材料功能层112、以及第二电极113厚度相同。
这里,光敏传感器件121、太阳能电池器件122、以及OLED发光单元11中的各结构层同层设置且厚度相同,从而本发明实施例提供的上述OLED显示基板10在不增加OLED显示基板10的整体厚度的基础上,集成了上述的显示、触控、太阳能充电的多种功能。从而使得该OLED显示基板10在具有导体、绝缘体触控以及实时充电功能的同时,仍然保持了整体轻薄化的结构设计。
进一步,针对上述光学感应单元12还包括太阳能电池器件122、第一开关管15、以及第二开关管16的情况,第一开关管15、第二开关管16、以及OLED发光单元11中的驱动晶体管与各自阳极或阴极的连接可以采用以下方式:
如图5所示,OLED发光单元11包括位于衬底基板100上的驱动晶体管(图中标记为TFT);其中,OLED显示基板10还包括覆盖驱动晶体管TFT、第一开关管15、以及第二开关管16的钝化层19;驱动晶体管TFT的漏极通过钝化层19上的第一过孔191与第一电极111相连;第一开关管15的漏极通过钝化层19上的第二过孔192与第三电极1211相连;第二开关管16的漏极通过钝化层19上的第三过孔193与第五电极1221相连。
驱动晶体管(TFT)与第一开关管15、第二开关管16中的栅极金属层、源漏极金属层可在同一构图工艺中形成,有源层可在同样制备方法中形成,以提高OLED显示基板10的制备效率。
这里,OELD显示基板还包括位于钝化层19上的界定出各个OLED发光单元11的界定层20。而为了使OLED发光单元11、光敏传感器件121、 以及太阳能电池器件122的各电极结构互不影响,界定层上设置有分别露出第一电极111、第三电极1211、以及第五电极1221的第一开口201、第二开口202、以及第三开口203;有机材料功能层112与第二电极113位于第一开口201内,第一光电转换层1212与第四电极1213位于第二开口202内,第二光电转换层1222与第六电极1223位于第三开口203内。
基于上述结构设计,用户可以任意方式,例如导体触摸方式(手指或触控笔的触摸)或绝缘体触摸方式(穿戴手套或通过普通书写笔的触摸)对上述的OLED显示基板10进行操控,从而为用户提供了更好的操作体验。
进一步,如图6所示,本发明实施例还提供了一种触控显示面板01,该触控显示面板01例如包括封装基板21、与封装基板21对盒的上述OLED显示基板10。
进一步,如图6所示,该触控显示面板01还可以包括:位于封装基板21与OLED显示基板10之间的触控电极层30;其中,触控电极层30用于在导体触控阶段感测触摸信号;光敏传感器件用于在绝缘体触控阶段感测触摸信号。
需要说明的是,触控电极层30可以采用感应触摸点耦合电容Cm的变化来获取触摸点位置的结构。
用户可自行选择触控显示面板01的触控实现方式。例如可以通过存储于上述触控显示面板01内部的可读取存储介质中的程序指令来完成。用户在使用上述的触控显示面板01的过程中,可以通过控制实现该程序指令的物理按键(如触控智能手机的侧边按键)来选择采用导体或绝缘体对上述的触控显示面板01进行触摸控制,从而使得电容式触控显示面板还兼具绝缘体触控的功能。
此外,与触控电极层位于封装基板之上的设计相比,本发明实施例提供的上述触控显示面板01中,触控电极层30集成于封装基板21下,因此不需要在触控电极层30上额外设置保护层来对其进行保护,从而减小了上述的触控显示面板01整体厚度,更符合显示装置轻薄化的需要。
这里,由于上述的OLED显示基板10中进一步还可以设置可实时充电的太阳能电池器件122,因此,当光学感应单元12中的太阳能电池器件122与光敏传感器件121采用共用驱动与传输电极线的设计时,如图7中的(a) 部分所示,太阳能电池器件122的工作时序与触控电极层30的工作时序相同。即当光敏传感器件121在绝缘体触控阶段工作时,太阳能电池器件122在相反的导体触控阶段工作。
例如,在绝缘体触控阶段,通过开启第一开关管15、同时关闭第二开关管16,开启光敏传感器件121、同时关闭太阳能电池器件122;在导体触控阶段,通过关闭第一开关管15、同时开启第二开关管16,关闭光敏传感器件121、同时开启太阳能电池器件122。
当光学感应单元12中的太阳能电池器件122与光敏传感器件121采用独立的驱动与传输电极线的设计时,如图7中的(b)部分所示,太阳能电池器件122可在导体触控阶段与绝缘体触控阶段一直工作。
进一步,参考图6中箭头所指的虚线框内结构所示,触控电极层30包括由绝缘层33相隔离的交叉设置的触控驱动电极31与触控感应电极32;其中,OLED发光单元11与触控驱动电极31、触控感应电极32均无重叠,以此来提高OLED发光单元11的出光效率;和/或,光学感应单元12与触控驱动电极31、触控感应电极32均无重叠,以此来提高光学感应单元12中的光学传感器件121、太阳能电池器件122的感光效率。
进一步,如图4A和图4B所示,第一子区A1中设置有5至10个OLED发光单元11;光学感应单元12位于每四个第一子区A1相互靠近的中心区域处。
在上述的结构设计中,两个相邻的触控感应电极Rx或两个相邻的触控驱动电极Tx之间的间距一般在0.5mm左右,故每四个第一子区A1相互靠近的中心区域处设置一个光学单元12,可以尽可能地减小由于设置有光学单元12而造成的对OLED显示基板10分辨率的影响;同时,每四个第一子区A1设置一个光学单元12的分布可以保证上述的触控显示面板01在绝缘体触控阶段具有较高的触摸点获取精度,从而为用户提供更好的使用体验。
在上述结构设计基础上,可以对上述触控显示面板01中的触控电极层21的位置设计灵活调整,同样可以实现上述的导体/绝缘体触控:
示例1、如图8A所示,触控电极层30位于封装基板21面向OLED显示基板10一侧;触控显示面板01还包括位于OLED显示基板10与封装基板21之间的封框胶40。
封框胶40例如可以由熔融玻璃材料构成,即采用Frit(熔融)封装的方式。
示例2、如图8B所示,触控电极层30位于封装基板21面向OLED显示基板10一侧;OLED显示基板10还包括封装OLED发光单元11、光学单元12的封装层50。
例如,OLED显示基板10的衬底基板100例如可以采用柔性基板,如采用聚对苯二甲酸乙二醇酯(polyethylene terephthalate,简称为PET)材料构成;相应的,封装基板也可采用薄膜材料的柔性基板,从而使得形成的上述触控显示面板01可以应用于柔性触控显示。
示例3、如图8C所示,触控电极层30位于OLED显示基板10面向封装基板21一侧;触控显示面板01还包括位于触控电极层30与OLED发光单元11、光学单元12之间的绝缘层33,以及位于OLED显示基板10与封装基板21之间的封框胶40。
例如,封框胶40例如可以由熔融玻璃材料构成,即采用Frit(熔融)封装的方式。
示例4、如图8D所示,触控电极层30位于OLED显示基板10面向封装基板21一侧;OLED显示基板10还包括位于触控电极层30与OLED发光单元11、光学单元12之间的绝缘层33,以及封装触控电极层30、OLED发光单元11、光学单元12的封装层50。
其中,封装层50可以采用具有良好隔离水氧特性、且厚度仅有几微米的TFE封装(Thin Film Encapsulation,薄膜封装),从而进一步减小上述触控显示面板01的整体厚度。
这里,在上述示例1至4中,光学单元12的具体结构设计可参见上述实施例,在此不再赘述。
本发明实施例还提供了一种显示装置,包括上述的触控显示面板01。
例如,上述显示装置示例地可以为具有触控功能的数码相框、手机、平板电脑等具有任何显示功能的产品或者部件,具体不作限定。
需要说明的是,本发明所有附图是上述的触控显示面板的简略的示意图,只为清楚描述本方案体现了与发明点相关的结构,对于其他的与发明点无关的结构是现有结构,在附图中并未体现或只体现部分。
以上所述仅是本发明的示范性实施方式,而非用于限制本发明的保护范围,本发明的保护范围由所附的权利要求确定。
本申请要求于2015年4月13日递交的中国专利申请第201510172765.8号的优先权,在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
