Description

有机电致光二极管显示器及其偏光片贴覆方法
【技术领域】
本发明涉及偏光片贴覆技术领域，特别是涉及一种有机电致光二极管显示器及其偏光片贴覆方法。
【背景技术】
由于OLED（有机电致光二极管）显示器需要在发光面上蒸镀上一层金属电极来构成二极管, 然而这层金属使得使用者在观看OLED显示器时会受到外界光反射的影响从而使得对比度下降, 影响观看品质, 特别是在强光下或是户外, 因此无论是上发光式或是下发光式的AMOLED显示器, 都需要贴上偏光片来阻挡外界光的反射。
现有技术中，贴覆偏光片的方法是先将黏着层制作在偏光片上，再将黏着层与有机电致光二极管器件贴合，然而，这种贴覆偏光片的方式容易在偏光片和有机电致光二极管器件之间产生气泡，尤其当基板为软性基板时，因为软性基板与偏光片的柔软度不同，黏合时更容易产生气泡，导致贴覆偏光片工序良率很低。
【发明内容】
本发明主要解决的技术问题是提供一种有机电致光二极管显示器及其偏光片贴覆方法，能够避免在贴覆偏光片工序过程中产生气泡，提升贴覆偏光片工序的良率。

为解决上述技术问题，本发明采用的又一个技术方案是：提供一种有机电致光二极管显示器。该有机电致光二极管显示器包括：偏光片层、黏着剂层、薄膜封装层、有机电致光二极管膜层以及基板。
其中，偏光片层由表面保护膜、第一保护层、偏光基体、第二保护层、感压胶、延迟层以及离型膜依序堆叠组成。
其中，黏着剂层的黏着剂为紫外光固化胶，采用紫外光照射黏着剂。
其中，有机电致光二极管显示器为有源矩阵有机电致光二极管显示器。
其中，基板为柔性基板。
本发明实施例有机电致光二极管显示器的偏光片的贴覆方法通过在偏光片上贴覆黏着剂，再把偏光片涂覆有黏着剂的表面与有机电致光二极管器件结合，经过加热或光线照射使得黏着剂固化而完成偏光片的贴覆，由于黏着剂处于胶态，在偏光片与有机电致光二极管器件结合的过程中还可以对偏光片进行微调，使得能够避免在贴覆偏光片工序过程中产生气泡，提升贴覆偏光片工序的良率。

在本实施例中，黏着剂为紫外光固化胶或红外光固化胶，当然，也可以是后固化紫外光固化胶等起黏着作用的其他类型的黏着剂，本发明对此不作限定。
步骤S102：将偏光片涂覆有黏着剂的表面与有机电致光二极管器件贴合。
其中，黏着剂处于胶态，使得偏光片与有机电致光二极管器件贴合的过程中可以进行微调，有机电致光二极管器件的薄膜封装层密封有机电致光二极管膜层，避免有机电致光二极管膜层与外界空气接触，空气中的水和氧气等成分对有机发光材料的寿命影响很大。
步骤S103：加热或光线照射黏着剂，使得偏光片与有机电致光二极管器件紧密贴合。
其中，采用不同的光线或加热方式对不同的黏着剂进行固化，当黏着剂采用紫外光固化胶时，采用紫外光照射黏着剂；当黏着剂采用红外光固化胶时，采用红外光照射或加热固化黏着剂。值得一提的是，当采用后固化紫外光固化胶时，由于后固化紫外光固化胶需在经过一段时间的紫外光照射后黏度才会大幅提升，需先对其进行紫外光照射之后再将偏光片涂覆有黏着剂的表面与有机电致光二极管器件贴合。
通过上述方式，本发明先对偏光片涂覆黏着剂，然后再将偏光片涂覆有黏着剂的表面与有机电致光二极管器件贴合，由于黏着剂处于胶态，且在贴合的过程中可进行微调，使得偏光片能更好地与有机电致光二极管器件贴合，避免气泡的产生，提高贴覆偏光片工序的良率。
请参阅图2，图2是本发明有机电致光二极管显示器的偏光片的贴覆方法另一实施例的流程示意图。该有机电致光二极管显示器包括但不限于有机电致光二极管器件，有机电致光二极管器件包括基板、有机电致光二极管膜层和薄膜封装层，薄膜封装层覆盖有机电致光二极管膜层，其中，在本实施例中，基板为玻璃或柔性基板。

步骤S202：将有机电致光二极管器件涂覆有黏着剂的表面与偏光片贴合。
其中，黏着剂处于胶态，使得偏光片与有机电致光二极管器件贴合的过程中可以进行微调，有机电致光二极管器件的薄膜封装层密封有机电致光二极管膜层，避免有机电致光二极管膜层与外界空气接触，空气中的水和氧气等成分对有机发光材料的寿命影响很大。
步骤S203：加热或光线照射黏着剂，使得有机电致光二极管器件与偏光片紧密贴合。
其中，采用不同的光线或加热方式对不同的黏着剂进行固化，当黏着剂采用紫外光固化胶时，采用紫外光照射黏着剂；当黏着剂采用红外光固化胶时，采用红外光或加热固化黏着剂。值得一提的是，当采用后固化紫外光固化胶时，由于后固化紫外光固化胶需在经过一段时间的紫外光照射后黏度才会大幅提升需先对其进行紫外光照射之后再将有机电致光二极管器件涂覆有黏着剂的表面与偏光片贴合。
值得一提的是，也可在偏光片和有机电致光二极管器件上均涂覆黏着剂，其达到的效果与本发明实施例一致，所以此种涂覆方式也应属于本发明保护范围。
通过上述方式，本发明先对有机电致光二极管器件涂覆黏着剂，然后再将有机电致光二极管器件涂覆有黏着剂的表面与偏光片贴合，由于黏着剂处于胶态，且在贴合的过程中可进行微调，使得偏光片能更好地与有机电致光二极管器件贴合，避免气泡的产生，提高贴覆偏光片工序的良率。

在本实施例中，该有机电致光二极管显示器优选为AMOLED（有源矩阵有机电致光二极管显示器），其包括薄膜封装层1、有机电致光二极管膜层2、基板3、黏着剂层4以及偏光片层5。薄膜封装层1覆盖有机电致光二极管膜层2，其中，基板3优选为柔性基板。
黏着剂层4为紫外光固化胶、红外光固化胶或后固化紫外光固化胶中的一种，当然，本领域技术人员也可以用其他起黏着作用的胶状物质代替，本发明对此不作限定。
请结合参阅图4，图4是图3中所示的有机电致光二极管显示器的偏光片层的结构示意图。偏光片层5由表面保护膜51、第一保护层52、偏光基体53、第二保护层54、感压胶55、延迟层56以及离型膜57依序堆叠组成。由于在本实施例中，采用黏着剂层4来贴覆偏光片层5，减少了原有偏光片层中位于延迟层56和离型膜57之间的感压胶。
