具体实施方式
显示面板产生牛顿环的主要原因是：盲孔内、外大气压的压力不等，导致位于盲孔上方的透明膜层会朝向盲孔内塌陷，进而导致盲孔两侧的透明膜层之间的距离不相等，当波长为λ的入射光线从位于上层的透明膜层射入时，波长为λ的入射光线在盲孔两侧的透明膜层之间的光程差不相等，如图1所示，当波长为λ的入射光线在盲孔两侧的透明膜层之间的光程差小于波长时，波长为λ的入射光线在盲孔两侧的透明膜层上几乎会同时进 行反射，形成反射光线λ1和反射光线λ2，反射光线λ1和反射光线λ2之间会出现光的干涉现象，从而出现牛顿环的现象，影响显示面板的显示效果。
为了解决上述问题，本申请实施例提供的阵列基板、显示面板和显示装置中，通过在至少一相邻的两层透明膜层之间设置光调节层，光调节层的折射率和光调节层的厚度的乘积大于二分之一的预设波列长度，例如，如图2所示，当波长为λ的入射光线从位于上层的透明膜层10射入时，光调节层增大了波长为λ的入射光线在相邻两层透明膜层之间的光程差，且该光程差大于波长为λ的入射光线的波长，因此，当波长为λ的入射光线从位于上层的透明膜层10射入时，在光调节层上方的透明膜层上形成的反射光线λ1先反射出去，在光调节层下方的透明膜层上形成的反射光线λ2后反射出去，这样，避免了反射光线λ1和反射光线λ2之间发生干涉，破坏了牛顿环的形成条件，从而消除了牛顿环现象，提高显示面板的显示效果。
为了使本申请实施例的上述目的、特征和优点能够更加明显易懂，下面将结合本申请实施例中的附图，对本申请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申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其它实施例，均属于本申请保护的范围。
参见图3所示，本申请一实施例提供的阵列基板100包括：依次层叠设置的至少两层透明膜层10，至少两层透明膜层10中，至少一相邻的两层透明膜层10之间设置有光调节层20，光调节层20的折射率和光调节层20的厚度的乘积大于二分之一的预设波列长度。
当预设波长光线射入上述阵列基板100时，预设波长光线在相邻两层透明膜层之间的相互干涉的条件为：
2nd＜＜L λ
其中，上述公式中的n为相邻两层透明膜层10之间的介质层的折射率，d为相邻两层透明膜层10之间介质层的厚度，L λ为预设波列长度。
当相邻两层透明膜层10之间的预设波长光线满足上述光的相互干涉 条件时，则会出现牛顿环现象。在本实施例中，通过在至少一相邻两层透明膜层10之间设置光调节层20，且光调节层20的折射率和光调节层20的厚度的乘积大于二分之一的预设波列长度，这样，增大了预设波长光线在相邻两层透明膜层10之间的光程差，破坏了相邻两层透明膜层10之间的光的相互干涉的条件，即破坏了牛顿环的形成条件，从而消除牛顿环现象。
光调节层20的材质可以选择二氧化钛、氧化锌等高折射率的材质，同时可以根据光调节层20的折射率，调整光调节层20的厚度，该光调节层20的厚度需满足阵列基板100整体厚度的需求；或者根据光调节层20的允许的厚度选择光调节层20的折射率，使得光调节层20的折射率和光调节层20的厚度的乘积大于二分之一的预设波列长度即可。
在本实施例中，光调节层20包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203；光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合；第一光调制层201的折射率在与该第一光调制层201相邻的透明膜层10的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在于该第二光调制层203相邻的透明膜层10的折射率和光程调节膜层202的折射率之间。这样，通过第一光调制层201和第二光调制层203，可以提升预设波长光线在光程调节膜层202的透过率，减小了预设波长光线在光程调节膜层202的反射强度，从而减小了光程调节膜层202的反射率，避免光程调节膜层202因反射率大而增加牛顿环现象。另外，由于光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度，因此，破坏了牛顿环的形成条件，从而消除牛顿环现象。
其中，第一光调制层201和第二光调制层203的材料可以为氟化锂层、氟化镁、氧化硅、可掺杂型石英膜或氧化硅/硅的复合膜层等材质，通过蒸镀、溅射、电子束蒸发、涂布、化学气相沉积(Chemical Vapor Deposition，CVD)等方式形成。而光程调节膜层202的材质可以选用二氧化钛、氧化锌等高折射率的材质，通过贴附、溅射、电子束蒸发、CVD、蒸镀等方式形成。
具体的，阵列基板100中的透明膜层10可以是两层，也可以是多层。 当阵列基板中的透明膜层10为两层时，光调节层20设置在两个透明膜层10之间；而当阵列基板100中的透明膜层10为多层时，可以在其中相邻的两层透明膜层10之间设置一个光调节层20，也可以在任意相邻的两个透明膜层10之间均设置有光调节层20，只要能够消除牛顿环现象即可。
至少两层透明膜层10中，其中一层透明膜层10可以为衬底11，与衬底11相邻的另一层透明膜层10可以为缓冲层12，如图4所示，通过在衬底11和缓冲层12之间设置光调节层20来破坏牛顿环的形成条件，消除牛顿环现象，为了方便描述和理解，在本实施例中，衬底11与缓冲层12之间设置的光调节层20用第一光调节层21来代替。
由于衬底11和缓冲层12之间会因制造、安装等误差存在间隙，或者在需要设置摄像头等装备的安装孔，因此，在大气压的压力下，衬底11容易朝向缓冲层12一侧塌陷，导致衬底11和缓冲层12之间的间距大小不一致，当预设波长光程射入衬底11和缓冲层12上时，预设波长光线在衬底11和缓冲层12之间的光程差大小不相等，局部光程差过小，导致射入衬底11和缓冲层12之间的预设波长光线在衬底11和缓冲层12上的反射时间差太小，从而导致预设波长光线在衬底11和缓冲层12上的反射光线之间发生相互干涉，从而出现牛顿环现象。
为此，本实施例在衬底11和缓冲层12之间设置第一光调节层21，且位于衬底11和缓冲层12之间的第一光调节层21的两侧分别与衬底11和缓冲层12贴合，其中，第一光调节层21的折射率与第一光调节层21的厚度的乘积大于二分之一的预设波列长度，这样，增大了预设波长光线在衬底11和缓冲层12之间的光程差，延迟了预设波长光线在衬底11上的反射时间，避免了预设波长光线在缓冲层12上的反射光线和衬底11上的反射光线之间发生相互干涉，即破坏了预设波长光线在衬底11和缓冲层12之间发生干涉的条件，破坏牛顿环的形成条件，从而避免产生牛顿环现象。
进一步的，为了避免第一光调节层21因反射率大而增加牛顿环现象，因此，在本实施例中，第一光调节层21也包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合，其中，第一光调 制层201与衬底11贴合，第二光调制层203与缓冲层12贴合，且第一光调制层201的折射率在衬底11的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在缓冲层12的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除衬底11和缓冲层12之间出现的牛顿环现象。
其中，衬底11可以是聚酰亚胺(Polyimide，简称为PI)、聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，简称为PET)、玻璃等材料制成的透明衬底11。
在上述实施例的基础上，参见图5和图6所示，缓冲层12包括靠近衬底11的第一缓冲层121，以及与第一缓冲层121平行且相对的第二缓冲层122；第一缓冲层121和第二缓冲层122之间设置有光调节层20，且位于第一缓冲层121和第二缓冲层122之间的光调节层20的两侧分别于第一缓冲层121和第二缓冲层122贴合。
为了方便描述和理解，在本实施例中，第一缓冲层121和第二缓冲层122之间设置的光调节层20用第二光调节层22来代替。
通过在第一缓冲层121和第二缓冲层122之间设置第二光调节层22，可以破坏第一缓冲层121和第二缓冲层122之间形成牛顿环的条件，从而消除第一缓冲层121和第二缓冲层122之间的牛顿环现象。
具体的，第二光调节层22包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合。在本实施例中，第一光调制层201与第一缓冲层121贴合，第二光调制层203与第二缓冲层122贴合，且第一光调制层201的折射率在第一缓冲层121的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在第二缓冲层122的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。因此，本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202 的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除第一缓冲层121和第二缓冲层122之间出现的牛顿环现象。
需要说明的是，第一光调制层21和第二光调制层22可以同时存在，也可以独立存在。
在一个可选的实施例中，参见图7所示，至少两层透明膜层10还包括设置于缓冲层12上的阵列电路层13；缓冲层12和阵列电路层13之间设置有光调节层20，且位于缓冲层12和阵列电路层13之间的光调节层20的两侧分别与缓冲层12和阵列电路层13贴合。
为了方便描述和理解，在本实施例中，缓冲层12和阵列电路层13之间设置的光调节层20用第三光调节层23来代替。
在本实施例中，通过在缓冲层12和阵列电路层13之间设置第三光调节层23，破坏了缓冲层12和阵列电路层13之间形成牛顿环的条件，从而消除缓冲层12和阵列电路层13之间的牛顿环现象。
具体的，第三光调节层23包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合。在本实施例中，第一光调制层201与缓冲层12贴合，第二光调制层203与阵列电路层13贴合，且第一光调制层201的折射率在缓冲层12的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在阵列电路层13的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。因此，本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除缓冲层12和阵列电路层13之间出现的牛顿环现象。
可选的，参见图8所示，至少两层透明膜层10中，其中一层透明膜层10为衬底11，与衬底11相邻的另一层透明膜层10为阵列电路层13；衬底11和阵列电路层13之间设置有光调节层20，且位于衬底11和阵列电路层13之间的光调节层20的两侧分别与衬底11和阵列电路层13贴合。
为了方便描述和理解，在本实施例中，衬底11和阵列电路层13之间设置的光调节层20用第四光调节层24来代替。
在本实施例中，通过在衬底11和阵列电路层13之间设置第四光调节层24，可以破坏衬底11和阵列电路层13之间形成牛顿环的条件，从而消除衬底11和阵列电路层13之间的牛顿环现象。
具体的，第四光调节层24包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合。在本实施例中，第一光调制层201与衬底11贴合，第二光调制层203与阵列电路层13贴合，且第一光调制层201的折射率在衬底11的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在阵列电路层13的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。因此，本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除衬底11和阵列电路层13之间出现的牛顿环现象。
可选的，阵列电路层13包括交替层叠设置的若干绝缘层和若干导电层，相邻的导电层和绝缘层之间也可以设置光调节层20，以消除相邻导电层和绝缘层之间的牛顿环现象。
通常的，若干导电层包括栅极层、金属层和阳极层，若干绝缘层包括位于栅极层和衬底11之间的栅极绝缘层，以及位于栅极层和金属层之间、位于相邻的金属层之间或位于金属层和阳极层之间的层间绝缘层。例如，靠近衬底11的导电层为栅极层，位于栅极层和衬底11之间的绝缘层为栅极绝缘层。
可选的，上述实施例中，光调节层20中的光程调节膜层202的材料可以为二氧化钛层或氧化锌层等高折射率的材料。
参见图9所示，在本实施例中，在相邻的两个透明膜层10中，至少一个透明膜层10靠近另一个透明膜层10的一侧上设置有凹槽101，使得在相邻两个透明膜层10之间形成空气层，该空气层为光调节层20。本实施例中，在位于下层的透明膜层10中设置有凹槽101，凹槽101的侧壁沿该透明膜层10的周向边缘延伸，凹槽101的顶部与位于上层的透明膜层10接触，凹槽101的侧壁以及相邻的两个透明膜层10形成空气层，该空 气层即为光调节层20。
参见图10所示，至少一个透明膜层10靠近另一个透明膜层10的一侧上设置有凸垫102，通过在该相邻的两个透明膜层之间设置凸垫102，使得在相邻两个透明膜层10之间形成的空气层，该空气层为光调节层20。
在本实施例中，通过在相邻两个透明膜层10之间的一个透明膜层10朝向另一个透明膜层10的表面上设置凹槽101，或者在相邻两个透明膜层10的相对的面上都设置凹槽101，或者还可以在相邻两个透明膜层10之前设置凸垫102等方式，增大相邻两个透明膜层10之间的距离，这时，相邻两个透明膜层10之间会形成一个空气层或者真空层，相邻两个透明膜层10之前的空气层或者真空层则形成一个特殊的光调节层20，即相邻两个透明膜层10之间距离则为光调制层20的厚度，根据上述实施例中提供的预设波长光线在相邻两层透明之间的相互干涉的条件可知，通过调整相邻两个透明膜层10之间的距离，便可以增大射入相邻两个透明膜层10之间的预设波长光线的光程差，当空气层或真空层的折射率与相邻两个透明膜层10之间的距离的乘积大于二分之一预设波列长度时，则可以破坏相邻两个透明膜层10之间的牛顿环的形成条件，从而消除牛顿环现象。
本申请还提供一种显示面板，包括上述实施例中提供的阵列基板100，下面以上述实施例中提供的阵列基板100为基础进行说明，参见图11所示，该显示面板包括阵列基板100，设置于阵列基板100上的发光层200，以及设置于发光层200上的封装层300；发光层200和封装层300之间设置有光调节层20，位于发光层200和封装层300之间的光调节层20的至少一侧与封装层300和发光层200贴合。
为了方便描述和理解，在本实施例中，发光层200和封装层300之间设置的光调节层20用第五光调节层25来代替。
在本实施例中，通过在发光层200和封装层300之间设置光调节层20，可以破坏发光层200和封装层300之间形成牛顿环的条件，从而消除发光层200和封装层300之间的牛顿环现象。
在一种可选的实施例中，参见图12，位于发光层200和封装层300之间的光调节层20的一侧与封装层300贴合，另一侧与发光层200之间形成有真空间隔空间400。
为了方便描述和理解，在本实施例中，封装层300和真空间隔空间400之间的光调节层20用第六光调节层251来代替。
具体的，第六光调节层251包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合。在本实施例中，第二光调制层203与封装层300贴合，第一光调制层201与发光层200之间形成真空间隔空间400。且第一光调制层201的折射率在真空间隔空间400的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在封装层300的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除发光层200和封装层300之间的牛顿环现象。
在另一种可选的实施例中，参见图13，位于发光层200和封装层300之间的光调节层20的一侧与发光层200贴合，另一侧与封装层300之间形成有真空间隔空间400。
为了方便描述和理解，在本实施例中，发光层200和真空间隔空间400之间的光调节层20用第七光调节层252来代替。
具体的，第七光调节层252包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合。在本实施例中，第一光调制层201与发光层200贴合，第二光调制层203与封装层300之间形成真空间隔空间400。且第一光调制层201的折射率在发光层200的折射率和光程调节膜层202的折射率之间；第二光调制层203的折射率在真空间隔空间400的折射率和光程调节膜层202的折射率之间；光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度。因此，本实施例首先通过第一光调制层201和第二光调制层203减小光程调节膜层202的反射率，再通过光程调节膜层202破坏牛顿环的形成条件，从而消除发光层200和封装层300之间的牛顿环现象。
在又一种可选的实施例中，参见图14，位于发光层200和封装层300 之间设置有两层光调节层25，其中一层光调节层251的一侧与封装层300贴合，另一层光调节层252的一侧与发光层200贴合；两层光调节层20之间形成有真空间隔空间400。
可以理解的是，在发光层200和封装层300之间，设置有上述实施例提供的第六光调节层251和第七光调节层252，通过第六光调节层251和第七光调节层252破坏发光层200和封装层300之间牛顿环的形成条件，从而消除牛顿环现象。
在上述实施例的基础上，为了避免发光层200和封装层300在大气压力下朝向真空间隔空间400大面积发生坍塌，通常，在真空间隔空间400内设置有若干支撑垫500，在本实施例中，参见图16所示，支撑垫500的一端与贴合在封装层300上的光调节层251相抵，另一端与发光层200相抵；或者，参见图15所示，支撑垫500的一端与封装层300相抵，另一端与贴合在发光层200上的光调节层252相抵；或者，参见图17所示，支撑垫500的一端与贴合在封装层300上的光调节层251相抵，另一端与贴合在发光层200上的光调节层252相抵。在本实施例中，通过设置支撑垫500和光调节层25来破坏发光层200和封装层300之间牛顿环的形成条件，从而消除发光层200和封装层300之间产生的牛顿环现象。
可选的，参见图18所示，显示面板的边缘设置有安装孔700，安装孔700对应的位置安装有摄像头；封装层300封盖安装孔700，安装孔700内还设置有位于摄像头和封装层300之间的光调节层20，位于安装孔700内的光调节层20与封装层300贴合。
为了便于理解和描述，在本实施例中，位于摄像头和封装层300之间的光调节层20用第八光调节层26代替。
为了避免封装层300在大气压的压力下朝向安装孔700内塌陷，导致预设波长光线在封装层300的塌陷区与摄像头之间的光程差变小，从而出现牛顿环现象，因此，在本实施例中，通过在摄像头和封装层300之间设置第八光调节层26，且第八光调节层26的折射率和第八光调节层26的厚度的乘积大于二分之一的预设波列长度，这样，第八光调节层26破坏了摄像头和封装层300之间形成牛顿环的条件，从而可以消除摄像头和封装层300之间的牛顿环现象。
其中，第八光调节层26的结构与上述实施例中提供的光调节层20的结构相同。
示例性的，若摄像头和封装层300之间的距离用d表示，空气或真空的折射率为1，因此，预设波长光线在摄像头和封装层300之间的光程差为2d，当在安装孔700内设置第八光调节层26后，若第八光调节层26的厚度为T s，折射率为n s，则预设波长光线在摄像头和封装层300之间的光程差由2d变为2d+(n s-1)*T s，增大了光程差，因此，可以延迟预设波长光线在摄像头处的反射时间，从而避免预设波长光线在封装层300上的反射光线和预设波长光线在摄像头处的反射光线之间发生相互干涉，进而消除牛顿环现象。
可选的，参见图19所示，显示面板还包括设置于封装层300上的触控层600，触控层600和封装层300之间设置有光调节层20，位于触控层600和封装层300之间的光调节层20的两侧分别与触控层600和封装层300贴合。
为了便于理解和描述，在本实施例中，位于摄像头和封装层300之间的光调节层20用第九光调节层27代替。
具体的，触控层600也配置为透明膜层10，并在触控层600和封装层300之间设置第九光调节层27，第九光调节层27包括依次层叠设置的第一光调制层201、光程调节膜层202和第二光调制层203，光程调节膜层202的两侧分别与第一光调制层201和第二光调制层203贴合，第一光调制层201与封装层300贴合，第二光调制层203与触控层600贴合，且第一光调制层201的折射率在封装层300的折射率和光程调节膜层202的折射率之间，第二光调制层203的折射率在触控层600的折射率和光程调节膜层202的折射率之间，光程调节膜层202的折射率和光程调节膜层202的厚度的乘积大于二分之一的预设波列长度，通过光程调节膜层202破坏了触控层600和封装层300之间形成牛顿环的条件，从而消除了触控层600和封装层300之间的牛顿环现象。
