具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本申请进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
在本申请的描述中,需要理解的是,术语“中心”、“横向”、“上”、“下”“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”以及“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。此外,需要说明的是,当元件被称为“形成在另一元件上”时,它可以直接连接到另一元件上或者可能同时存在居中元件。当一个元件被认为是“连接”另一个元件,它可以直接连接到另一元件或者同时存在居中元件。相反,当元件被称作“直接在”另一元件“上”时,不存在中间元件。
将摄像头等感光器件设置在透明显示面板下方时,拍照得到的照片容易出现模糊。出现这个问题的原因在于,电子设备的显示屏体内存在导电走线,外部光线经过这些导电走线时会造成较为复杂的衍射强度分布,从而出现衍射条纹,进而会影响摄像头等感光器件的正常工作。例如,位于透明显示区域之下 的摄像头工作时,外部光线经过显示屏内的导线走线后会发生较为明显的衍射,从而使得摄像头拍摄到的画面出现失真。
图1为传统的导电走线的结构示意图。参见图1,传统的导电走线为条状。由于光在穿过狭缝、小孔或者圆盘之类的障碍物时,会发生不同程度的弯散传播,从而偏离原来的直线传播,这种现象称之为衍射。衍射过程中,衍射条纹的分布会受到障碍物尺寸的影响,例如狭缝的宽度、小孔的尺寸等。具有相同宽度的位置处产生的衍射条纹的位置一致,此时会出现较为明显的衍射效应。当光线经过传统的显示面板时,由于显示面板上具有周期排布的条状的导电走线,在不同位置处产生的衍射条纹均具有相同的位置,因此会产生较为明显的衍射效应,不利于设置于该显示面板下方的感光器件的正常工作。
为解决上述问题,本申请一实施例提供了一种显示面板,其能够很好的解决上述问题。图2为一实施例中的显示面板的示意图,参见图2,该显示面板包括基板110以及设置在基板110上的多个波浪形的第一电极120。多个第一电极120沿相同的方向并行延伸,且相邻的第一电极120间具有间距。在本实施例中,由于第一电极120为波浪形,因此在第一电极120的延伸方向上,其宽度为连续变化或者间断变化。宽度连续变化是指第一电极120上的任意两个相邻位置处的宽度不相同。图2中,第一电极120的延伸方向为其长度方向,即图中的Y方向。
在第一电极120的延伸方向上,第一电极120的宽度(即图中的第一电极120在X方向的长度)间断变化。而宽度间断变化是指:在第一电极120上存在部分区域内相邻两个位置的宽度相同,而在部分区域内相邻两个位置的宽度不相同。在本实施例中,多个第一电极120在基板110上规则排布,因此,相邻两个第一电极120之间的间隙在平行于第一电极120的延伸方向上也呈现为连 续变化或者间断变化。第一电极120在延伸方向上,无论其宽度是连续变化还是间断变化都可以为周期性变化,一个变化周期的长度可以对应于一个像素的宽度。
上述显示面板中设置有多个波浪形的第一电极120,在第一电极120的延伸方向上,第一电极120的宽度连续变化或者间断变化,从而使得相邻第一电极120具有连续变化的间距或者间断变化的间距。因此在第一电极120的不同宽度位置以及相邻第一电极120的不同间距之间,产生的衍射条纹的位置不同,不同位置处的衍生效应相互抵消,从而可以有效减弱衍射效应,进而确保摄像头设置在该透明显示面板下方时,拍照得到的图形具有较高的清晰度。
在一实施例中,为了提高显示面板的透光率,显示面板的各导电走线均采用透明导电金属氧化物制备而成,如第一电极120采用透明导电金属氧化物制备而成。例如,第一电极120可以采用ITO(氧化铟锡)或氧化铟锌(IZ0)制备而成。进一步的,为了在保证高透光率的基础上,为减小各导电走线的电阻,第一电极120还可以采用铝掺杂氧化锌、掺杂银的ITO或者掺杂银的IZ0等材料制备而成。
在一实施例中,第一电极120在自身延伸方向具有对称结构,具体可以参见图2。由于第一电极120的宽度的设置会直接影响显示面板中的像素开口,从而对显示面板的像素开口率产生影响。将第一电极120设置为对称结构可以确保显示面板上的各像素单元能够具有相同或者相近的开口率,而不会出现不同位置上的像素单元的开口率相差较大导致影响显示面板的显示效果的问题。
在一实施例中,第一电极120在延伸方向上的两条边均为波浪形,如图2所示。延伸方向上的两条边的波峰T相对设置且波谷B相对设置。本实施例中,两条边均由相同曲率半径的圆弧形边相连而成。在其他的实施例中,两条边也 可以均由相同曲率半径的椭圆形边相连而成,如图3所示。通过将第一电极120的两边设置成由圆弧形或者椭圆形相连形成的波浪形,可以确保第一电极120上产生的衍射条纹能够向不同方向扩散,进而降低衍射效应。
在一实施例中,在第一电极120的波谷相对处设置有连接部122,如图4所示。连接部122为条状。连接部122的宽度W应该大于X微米,且小于第一电极120上的最大宽度。X为最小工艺尺寸,在本实施例中为4微米,在其他的实施例中还可以更小。在一实施例中,第一电极120上相邻两个连接部122之间的区域对应一个像素开口,连接部122则对应于相邻两个像素开口之间的间隙。通过对连接部122的宽度W的调整,可以实现对第一电极120上的电阻大小的调整,以使得其满足使用需求。在其他的实施例中,连接部122也可以采用其他不规则结构,如中间小两端大的形状,或者采用中间大两端小的形状。在另一实施例中,第一电极120上设置有多个凸起124,如图5所示。多个凸起124的边为直线和/或曲线。在本实施例中,多个凸起124的边均为曲线。通过在第一电极120上设置多个凸起124,能够进一步打乱第一电极120各处的宽度的均匀性分布,从而降低衍射效应。
在一实施例中,上述显示面板为PMOLED(被动矩阵有机电激发光二极管)显示面板。此时,该显示面板还包括与第一电极120层叠设置的第二电极140,如图6所示。在第一电极120和第二电极140之间设置有绝缘层130。绝缘层130用于实现第一电极120和第二电极140之间的电绝缘。该绝缘层为无机绝缘层或者有机绝缘层,还可以为同时包含有机和无机层的复合结构。为了提高显示面板的透光率,绝缘层材料优选SiO 2,SiN x以及Al 2O 3等。
第二电极140的延伸方向与第一电极120的延伸方向相互垂直,从而在交叠区域形成显示面板的发光区域,如图7所示。其中,第一电极120为阳极, 第二电极140为阴极。在本实施例中,每个阳极用于驱动一行/列或者多行/列子像素。通常,一个像素(或者像素单元)至少包括红绿蓝三个子像素。在其他的实施例中,一个像素单元也可以包括红绿蓝白四个子像素。子像素的排布方式可以为RGB子像素并行排列、V型排列以及PenTile排列等。在本申请中均以呈RGB子像素并行排列的像素单元为例进行说明。可以理解,本实施例中的显示面板也可以适用于除了RGB子像素排列之外的其他排列方式。
在一实施例中,每个阳极用于驱动一行/列像素单元内的所有子像素。也即在本实施例中,每个阳极用于驱动一行/列像素单元内的红绿蓝三列子像素。此时阳极的形状采用如图2所示的形状,即阳极在延伸方向上的两条边均为波浪形且两条边的波峰T相对设置,波谷B相对设置。因此,在波峰T相对处存在最大宽度W1,在波谷B相对处存在最小宽度W2。其中,波峰T相对处的宽度W1为30微米~(A-X)微米,波谷B相对处的宽度W2为X微米~W1。A为像素大小,X为最小工艺尺寸,且A大于(30+X)微米。像素大小A需要根据显示面板的尺寸以及显示面板上的像素总数来确定。X为最小工艺尺寸,在本实施例中为4微米,在其他的实施例中还可以更小。
在一实施例中,像素均为方形像素,也即其长宽均具有相同的尺寸。此时像素大小A等于显示面板的面积除以像素总数后开平方所得到的结果。在其他的实施例中,波谷B相对处的宽度也可以小于4微米,只要制备工艺能力能够实现且满足其电学特性(如电阻特性)等要求即可。在另一实施例中,阳极规则排布在基板110上,也即相邻两个阳极的距离是固定的,从而导致相邻两个阳极之间的间距也会随着阳极宽度的变化而发生变化。因此,两个阳极的波峰相对处间具有最小间距D1,并在两个阳极的波谷位置相对处具有最大间距D2。其中,最小间距D1为(A-W1)。最大间距D2为(A-W2)。
在一实施例中,阴极的形状与阳极的形状相同,均为波浪形。此时,阴极与阳极一样,用于驱动一行/列像素单元内的所有子像素,从而实现对同一行/列像素单元内的所有子像素的控制,图中仅以多个第一电极(即阳极)的沿x方向排列,多个第二电极(即阴极)沿y方向依次排列为例进行说明。
在另一实施例中,阴极为在两个波谷相对处具有条状的连接部的电极结构,也即如图7所示。此时,阴极在两条边的波峰相对处同样具有最大宽度W3并在波谷相对处具有最小宽度W4。同理,相邻两个阴极在波峰处的间距为最小间距D3,而在波谷处的最大间距则为D4。此时,W3为(W1-X)微米,W2则为X微米~W3微米。X为最小工艺尺寸,在本实施例中为4微米,在其他的实施例中还可以更小。可以理解,阳极和阴极的尺寸可以根据需要进行设定,上述实施例也不构成对本申请的唯一限定。
在其他的实施例中,每个阴极对应驱动的像素列数/行数为M,每个阳极对应驱动的像素的列数/行数为N,则M应该大于或者等于N的3倍。具体地,采用RBG子像素构成一个像素单元,阴极对应驱动的子像素的列数/行数M为N的3倍。在其他的实施例中,如果采用RGBW子像素构成一个像素单元,则阴极对应驱动的子像素的列数/行数M为4N。可以理解,在其他的实施例中,也可以由阴极驱动列像素而阳极驱动行像素,二者仅仅是阳极和阴极的排布方向不同而已。
图8为另一实施例中的PMOLED显示面板中的阴极和阳极的结构示意图。此时,一个像素单元包括红绿蓝三个子像素,因此每个阳极120用于驱动一列像素单元,每个阴极140用于驱动一行子像素。阳极的图案以及尺寸可以参照图2,也即其在波峰T相对处的宽度W1为30微米~(A-X)微米,波谷B相对处的宽度W2为X微米~W1,最小间距D1为(A-W1),最大间距D2为(A-W2)。X为最 小工艺尺寸。
参见图8,阴极的两条边的波峰相对位置处的宽度W3为X微米~((A-X)/3)微米。可以理解,在其他实施例中,当一个像素单元内的子像素为N时,阴极140的两条边的波峰T相对位置处的宽度W3为X微米~((A-X)/N)微米。在本实施例中,阴极140的两条边的波谷相对处的宽度W4为X微米~W1,最小间距D3为(A-W3),最大间距D4为(A-W4)。其中A为像素大小,X为最小工艺尺寸。在上述实施例中,相邻电极的间距均在4微米~20微米之间。
在另一实施例中,也可以将图8中的阳极作为阴极,而阴极作为阳极,也即每个阴极用于驱动一列子像素,而每个阳极则用于驱动一行像素单元中的所有子像素。
在另一实施例中,上述显示面板还可以为AMOLED(主动矩阵有机发光二极体)显示面板。此时,基板110为TFT阵列基板。第一电极包括设置在TFT阵列基板上的各类导电走线。第一电极的宽度尺寸需要根据导电走线的宽度设计来进行设计。其中,导电走线包括扫描线、数据线以及功率线中的至少一种。例如,可以将TFT阵列基板上的所有导电走线如扫描线、数据线以及功率线进行改进,采用如图2所示的电极形状。通过将TFT阵列基板上的导电走线改成图2中的波浪形的电极形状,可以确保在导线走线的延伸方向上,光线经过在不同宽度位置处以及相邻走线的不同间隙处时能够形成具有不同位置的衍射条纹,不同位置的衍射效应相互抵消,进而减弱衍射效应,以使得放置于其下方的感光器件能够正常工作。
在一实施例中,在显示面板为AMOLED(主动矩阵有机发光二极体)显示面板时还包括设置在基板上方的阳极层。阳极层包括阳极阵列。阳极阵列由多个相互独立的阳极构成。阳极的形状可以为圆形、椭圆形或者哑铃形。图9为采 用圆形的阳极形成的阳极阵列的示意图。图10为采用哑铃形的电极形成的阳极阵列的示意图。通过将阳极形状改为圆形、椭圆形或者哑铃形,可以确保光线经过阳极层时,在阳极的不同宽度位置处同样能够产生具有不同位置以及扩散方向的衍射条纹,不同位置和方向的衍射条纹相互抵消,从而弱化衍射效应。进一步的,各个子像素也可设置为图9和图10所示的圆形、椭圆形或者哑铃形,以弱化衍射效应。并且,圆形、椭圆形或者哑铃形可在最大限度上扩大各个子像素的面积,进一步提高透光率。
在一实施例中,上述显示面板可以为透明或者半透半反式的显示面板。显示面板的透明可以通过采用透光率较好的各层材料来实现。例如,各层均采用透光率大于90%的材料,从而使得整个显示面板的透光率可以在70%以上。进一步的,各结构膜层均采用透光率大于95%的材料,进一步提高显示面板的透光率,甚至使得整个显示面板的透光率在80%以上。具体地,可以将导电走线如阴极和阳极等设置为ITO、IZO、Ag+ITO或者Ag+IZO等,绝缘层材料优选SiO 2,SiN x以及Al 2O 3等,像素定义层140则采用高透明材料。
可以理解,显示面板的透明还可以采用其他技术手段实现,上述显示面板的结构均可以适用。透明或者半透半反式的显示面板处于工作状态时能够正常显示画面,而当显示面板处于其他功能需求状态时,外部光线可以透过该显示面板照射到置于该显示面板之下的感光器件等。
本申请一实施例还提供一种显示屏。该显示屏具有至少一个显示区。各显示区均用于显示动态或者静态画面。至少一个显示区包括第一显示区。第一显示区设置有如前述任一实施例中所提及的显示面板。第一显示区下方可以设置感光器件。由于第一显示区采用了前述实施例中的显示面板,因此当光线经过该显示区域时,不会产生较为明显的衍射效应,从而能够确保位于该第一显示 区下方的感光器件能够正常工作。可以理解,第一显示区在感光器件不工作时,可以正常进行动态或者静态画面显示,而在感光器件工作时,第一显示区随着整体显示屏的显示内容的变化而变化,如显示正在拍摄的外部图像,或者第一显示区也可以处于不显示状态,从而进一步确保感光器件能够透过该显示面板正常进行光线采集。
图11为一实施例中的显示屏的结构示意图,该显示屏包括第一显示区910和第二显示区920。其中,第一显示区910的透光率大于第二显示区920的透光率。第一显示区910的下方可设置感光器件930。第一显示区910设置有如前述任一实施例中所提及的显示面板。第一显示区910和第二显示区920均用于显示静态或者动态画面。由于第一显示区910采用了前述实施例中的显示面板,因此当光线经过该显示区域时,不会产生较为明显的衍射效应,从而能够确保位于该第一显示区910下方的感光器件930能够正常工作。可以理解,在感光器件930不工作时,第一显示区910可以正常进行动态或者静态画面显示,而在感光器件930工作时,可以处于不显示状态,从而确保感光器件930能够透过该显示面板正常进行光线采集。在其他的实施例中,第一显示区910和第二显示区920的透光率也可以相同,从而使得整个显示面板具有较好的透光均一性,确保显示面板具有较好的显示效果。
在一实施例中,第一显示区910设置的显示面板为PMOLED显示面板或AMOLED显示面板,在第二显示区920设置的显示面板为AMOLED显示面板,从而形成由PMOLED显示面板和MOLED显示面板构成的全面屏。
本申请另一实施例还提供一种显示终端。图12为一实施例中的显示终端的结构示意图,该显示终端包括设备本体810和显示屏820。显示屏820设置在设备本体810上,且与该设备本体810相互连接。其中,显示屏820可以采用前 述任一实施例中的显示屏,用以显示静态或者动态画面。
图13为一实施例中的设备本体810的结构示意图。在本实施例中,设备本体810上可设有开槽区812和非开槽区814。在开槽区812中可设置有诸如摄像头930以及光传感器等感光器件。此时,显示屏820的第一显示区的显示面板对应于开槽区814贴合在一起,以使得上述的诸如摄像头930及光传感器等感光器件能够透过该第一显示区对外部光线进行采集等操作。由于第一显示区中的显示面板能够有效改善外部光线透射该第一显示区所产生的衍射现象,从而可有效提升显示设备上摄像头930所拍摄图像的质量,避免因衍射而导致所拍摄的图像失真,同时也能提升光传感器感测外部光线的精准度和敏感度。
上述电子设备可以为手机、平板、掌上电脑、ipod等数码设备。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
