Description

一种位相延迟装置及其制备方法、显示设备 技术领域
本说明书涉及显示技术领域，尤其涉及一种位相延迟装置及其制备方法、显示设备。
背景技术
随着有机发光二极管(Organic Light Emitting Diode，OLED)技术的迅速发展，越来越多的如手机、平板电脑等电子设备开始采用OLED显示面板。在OLED显示面板内部，为解决由于OLED显示面板内部的金属对自然光的反射导致的对比度的问题，OLED显示器可以使用位相延迟装置(如圆偏光片)来控制这种反射。
圆偏光片可以由线性偏振片和两个叠加波片组成，两个叠加的波片可以分别为一个二分之一波片和一个四分之一波片，由于圆偏光片需具备宽波段的表现，所以，四分之一波片与线性偏振片的快轴夹角，与二分之一波片与线性偏振片的快轴夹角不同。
所以，在制备圆偏光片时，需要分别对二分之一波片和四分之一波片基于不同的配向角度进行一次配向(即需要进行至少2次配向)，由于配向工艺的复杂度高，所以多次配向会导致位相延迟装置的制备效率低，装置良性率差。

具体实施方式
本说明书实施例提供一种位相延迟装置及其制备方法、显示设备。
为了使本技术领域的人员更好地理解本说明书中的技术方案，下面将结合本说明书实施例中的附图，对本说明书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说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本说明书保护的范围。
实施例一
图1为本说明书实施例提供的位相延迟装置的结构示意图一，该位相延迟装置包括：线性偏振层200、第一配向层300、第一液晶层400和第二液晶层500；
线性偏振层200位于光源100的一侧，用于将接收到的光线转换为线性偏振光。光源100可以是任意能够发出自然光的光源100，线性偏振层200可以包括任意能够将光源100发出的自然光转换为线性偏振光的装置，如线性偏振片、线栅起偏器等。
第一配向层300可以位于线性偏振层200远离光源100的一侧，用于基于预设配向角度对第一液晶层400的液晶进行配向。其中，如图2所示，预设配向角度可以是第一液晶层400的液晶排列方向与线性偏振层200的快轴之间的夹角，预设配向角度可以为预设角度范围内的任意配向角度，如预设角度范围可以为5°～20°，预设配向角度可以为14°，即第一配向层300可以基于14°，对第一液晶层400的液晶进行配向，以使第一液晶层400的光轴与线性偏振层200的快轴之间的夹角为14°。
其中，在进行第一配向层300的配向时，可以采用光配向方式，除以之外，还可以有摩擦配向等配向方式，可以根据实际应用场景的不同而有所不同，本发明实施例对第一配向层300的配向工艺不做具体的限定。
第一液晶层400可以位于第一配向层300中远离光源100的一侧，用于将 线性偏振光转换为椭圆偏振光。由于在第一配向层300基于预设配向角度对第一液晶层400的液晶进行了配向，所以，第一液晶层400的液晶在涂布后会按照预设配向角度对应的方向进行排列。第一配向层300制作完成后，可以对第一液晶层400进行涂布，然后可以使用UV光固化对第一液晶层400进行固化工艺。
由于第一液晶层400内的液晶不存在旋转，所以，第一液晶层400内的液晶从顶部(即与第一配向层300相邻的一侧)到底部(即与第二液晶层500相邻的一侧)只有一种配向方向。
第二液晶层500可以位于第一液晶层400中远离第一配向层300的一侧，第二液晶层500可以包括第一子部分501、第二子部分502和第三子部分503。其中，第一子部分501可以为第二液晶层500与第一液晶层400相邻的一侧，即如图1所示，第一子部分501可以为第二液晶层500的顶部，第二子部分502可以为第二液晶层500的内部，第三子部分503可以为第二液晶层500的底部。
其中，第一液晶层400和第二液晶层500采用的液晶材料可以是常规的反应型液晶，也可以采用负性分布的反应型液晶，可以根据实际应用场景的不同而有所不同，本发明实施例对此不做具体限定。
第一子部分501可以与第一液晶层400相邻，第一子部分501的液晶配向角度与第一液晶层400的液晶配向角度相同。由于通过第一配向层300对第一液晶层400进行配向时，用于对第一液晶层400进行配向的锚定能可以穿过第一液晶层400，到达第二液晶层500的第一子部分501，所以，在锚定能的作用下，第一子部分501的液晶配向角度可以与第一液晶层400的液晶配向角度相同，即第一子部分501的液晶配向角度可以为预设配向角度。
第二子部分502可以为具有预设螺旋角度的螺旋结构，其中，预设螺旋角度可以为根据实际配向需求确定的螺旋角度，如螺旋角度可以为80°～90°。第二子部分502的螺旋结构的旋转方向可以是自上而下的旋转方向，即第二子部分502的旋转方向与第一液晶层400的光轴相对线性偏振层200光轴的旋转 方向相同。
其中，为实现第二子部分502的螺旋结构，可以通过对向列相液晶添加手性剂来达成，除此之外还可以有多种实现方式，本发明实施例对此不做具体限定。
第三子部分503的液晶配向角度可以由预设配向角度和预设螺旋角度确定，例如，预设配向角度为14°，螺旋角度为80°～90°，则第三子部分503的液晶配向角度可以为94°～104°。
第二液晶层500可以用于通过第二子部分502的螺旋结构将椭圆偏振光转换为圆偏振光。光源100在发出自然光后，可以经由线性偏振层200转换为线性偏振光，线性偏振光可以在第一液晶层400的作用下转换为椭圆偏振光，在通过第二液晶层500的第二子部分502的螺旋结构，将椭圆偏振光转换为圆偏振光。通过一次配向操作，就可以实现宽波段的效果，而不需要对第二液晶层500进行配向，就可以通过第二液晶层500的第二子部分502的螺旋结构，将光源100发出的自然光转换为圆偏振光，制备工序简单，可以提高生产效率，即可以提高位相延迟装置的制备效率以及良性率。
本发明实施例提供一种位相延迟装置，该位相延迟装置包括：线性偏振层、第一配向层、第一液晶层和第二液晶层，线性偏振层位于光源的一侧，用于将接收到的光线转换为线性偏振光，第一配向层位于线性偏振层远离光源的一侧，用于基于预设配向角度对第一液晶层的液晶进行配向，第一液晶层位于第一配向层中远离光源的一侧，用于将线性偏振光转换为椭圆偏振光，第二液晶层位于第一液晶层中远离第一配向层的一侧，第二液晶层包括第一子部分、第二子部分和第三子部分，第一子部分与第一液晶层相邻，第一子部分的液晶配向角度与第一液晶层的液晶配向角度相同，第二子部分为具有预设螺旋角度的螺旋结构，第三子部分的液晶配向角度由预设配向角度和预设螺旋角度确定，第二液晶层用于通过第二子部分的螺旋结构将椭圆偏振光转换为圆偏振光。这样，由于该位相延迟装置中的第二液晶层包括具有螺旋结构的第二子部分，所以， 在制备该位相延迟装置时，只需要通过第一配向层对第一液晶层进行一次配向，就可以通过第二液晶层中的第二子部分，将光源发出的自然光转换为圆偏振光，由于配向操作次数少，所以可以避免多次配向导致的制备效率低的问题，同时也可以提高装置的良性率。
实施例二
本发明实施例提供又一种位相延迟装置。该位相延迟装置包含了上述实施例一的位相延迟装置的全部功能单元，并在其基础上，对其进行了改进，改进内容如下：
第一液晶层400的位相延迟量可以为第一预设值。其中，对于不同的光波段，可以选取不同的第一预设值作为第一液晶层400的位相延迟量。例如，对于绿光550nm波段，第一液晶层400的位相延迟量可以为190nm(即可以选取190nm作为第一预设值)。
第二液晶层500的位相延迟量可以为基于第一预设值和预设补偿值确定的第二预设值，例如，第二预设波值可以为第一预设值与预设补偿值的乘积，假设预设补偿值为预设补偿范围(如85％～100％)内的任意一个补偿值，那么，可以从预设补偿范围中选取任意一个补偿值，用以确定第二预设值，如可以假设第一预设值为190nm，预设补偿值为95％，则对应的第二预设值可以为190nm*95％。此外，第二预设值的确定方法可以有多种，本发明实施例对此不做具体限定。在确定了第二预设值后，可以确定第二液晶层500的位相延迟量，以基于该位相延迟量对第一液晶层400进行位相延迟量的宽波段补偿。
如图3所示，位相延迟装置还可以包括第二配向层600，第二配向层600可以位于第一液晶层400和第二液晶层500之间，用于在第一子部分501的液晶配向角度与第一液晶层400的液晶配向角度不同时，基于预设配向角度对第一子部分501的液晶进行配向。由于在实际操作中，由于存在第一配向层300的锚定能不够强等因素，可能会导致第一子部分501的液晶配向角度与第一液 晶层400的液晶配向角度不同，所以，为提高位相延迟装置的良性率，可以在第一液晶层400和第二液晶层500之间布置第二配向层600，以在第二配向层600基于预设配向角度对第二液晶层500的第一子部分501的液晶进行配向，使第一子部分501的液晶配向角度与第一液晶层400的液晶配向角度相同。
如图3所示，位相延迟装置还可以包括折射膜层700，折射膜层700与第二液晶层500中的第三子部分503相邻，用于调整圆偏振光对应的视角，以实现广视角的效果。
折射膜层700的折射率可以满足N Z>N X＝N Y，其中，N X为折射膜层的滞后相轴方向的折射率，N Y为折射膜层的超前相轴方向的折射率，N Z为折射膜层的厚度方向的折射率，例如，折射膜层700可以为Posi-C层。
第一液晶层400和第二液晶层500可以包括反应型聚合物液晶(Reactive Mesogen，RM)，可以在RM中参杂光配向分子，简化配向的过程，提高生产效率。例如，可以在基材(如柔性超波基材)上涂布RM和配向分子的混合物，用偏振的紫外光进行固化，以完成第一液晶层400的配向和制作，以及第二液晶层500的制作。
光源100在发出自然光后，可以经由线性偏振层200转换为线性偏振光，线性偏振光可以在第一液晶层400的作用下，转换为椭圆偏振光，在通过第二液晶层500的第二子部分502的螺旋结构，将椭圆偏振光转换为圆偏振光，最后可以经由折射膜层700，调整圆偏振光对应的视角，以实现广视角的效果。其中，如果第一子部分501的液晶配向角度与第一液晶层400的液晶配向角度不同，还可以通过第二配向层600基于预设配向角度，对第一子部分501的液晶进行配向，以保证第一子部分501的液晶配向角度与第一液晶层400的液晶配向角度相同，提高位相延迟装置的良性率。
本发明实施例提供一种位相延迟装置，该位相延迟装置包括：线性偏振层、第一配向层、第一液晶层和第二液晶层，线性偏振层位于光源的一侧，用于将接收到的光线转换为线性偏振光，第一配向层位于线性偏振层远离光源的一侧， 用于基于预设配向角度对第一液晶层的液晶进行配向，第一液晶层位于第一配向层中远离光源的一侧，用于将线性偏振光转换为椭圆偏振光，第二液晶层位于第一液晶层中远离第一配向层的一侧，第二液晶层包括第一子部分、第二子部分和第三子部分，第一子部分与第一液晶层相邻，第一子部分的液晶配向角度与第一液晶层的液晶配向角度相同，第二子部分为具有预设螺旋角度的螺旋结构，第三子部分的液晶配向角度由预设配向角度和预设螺旋角度确定，第二液晶层用于通过第二子部分的螺旋结构将椭圆偏振光转换为圆偏振光。这样，由于该位相延迟装置中的第二液晶层包括具有螺旋结构的第二子部分，所以，在制备该位相延迟装置时，只需要通过第一配向层对第一液晶层进行一次配向，就可以通过第二液晶层中的第二子部分，将光源发出的自然光转换为圆偏振光，由于配向操作次数少，所以可以避免多次配向导致的制备效率低的问题，同时也可以提高装置的良性率。
实施例三

如图4所示，显示设备可以包括依次相邻的玻璃盖板、位相延迟装置、触控面板层、显示层(如OLED显示层)，以及保护层(如背面保护层)。
其中，玻璃盖板可以与位相延迟装置中的线性偏振层200相邻，触控面板层可以与位相延迟装置中的折射膜层700相邻。

在S504中，基于配向角度与螺旋角度的预设对应关系，确定与预设配向角度对应的第二液晶层的第二子部分的螺旋角度，以使椭圆偏振光在第二子部分的螺旋结构的作用下，转换为满足预设光转换需求的圆偏振光。
其中，光转换需求可以用于判断第二液晶层的第三子部分的配向角度是否满足预设角度范围。
在实施中，可以基于历史配向角度、历史螺旋角度以及光转换需求，确定配向角度与螺旋角度的预设对应关系，在基于配向角度与螺旋角度的预设对应关系，确定与预设配向角度对应的第二液晶层的第二子部分的螺旋角度。
其中，配向角度与螺旋角度的预设对应关系的确定方法可以有多种，可以根据实际应用场景的不同而有所不同，本发明实施例对此不做具体限定。

在S602中，在第一配向层基于预设配向角度，对第一液晶层的液晶进行配向。
在S604中，获取第二液晶层的第一子部分的液晶配向角度。
由于在实际操作中，可能存在由于锚定能不够或操作偏差等因素，导致第二液晶层的第一子部分的液晶配向角度与第一液晶层的配向角度不同，所以，可以对第二液晶层的第一子部分的液晶配向角度进行检测，以使第一子部分的液晶配向角度与预设配向角度相同，即在S604后，可以继续执行S606或S608。
在S606中，在检测到液晶配向角度与预设配向角度不同的情况下，在第二配向层，基于预设配向角度，对第二液晶层的第一子部分的液晶进行配向。

在实施中，在检测到液晶配向角度与预设配向角度不同的情况下，可以获取此时第一液晶层对应的第一锚定能，并将该第一锚定能作为预设锚定能，然后将锚定能大于该预设锚定能的液晶层确定为第一液晶层，以保证第一液晶层的液晶配向角度与第一子部分的液晶配向角度相同。
此外，上述预设锚定能的确定方法是一种可选地、可实现的确定方法，在实际应用场景中，还可以多种确定方法，可以根据实际应用场景的不同而有所不同，本发明实施例对此不做具体限定。
