其中,所述不锈钢层303靠近所述支撑机构304一侧的表面内嵌有多个第一磁性体305,所述支撑机构304靠近所述不锈钢层303一侧的表面内嵌有多个第二磁性体306,每一所述第二磁性体306的位置与每一所述第一磁性体305的位置相对应并组成多个磁性区域,每一所述第一磁性体305、每一所述第二磁性体306通过数据线与一控制器组成一闭合回路。
所述可折叠显示装置处于弯折状态时,在所述控制器的作用下,通过电流控制分别改变了所述第一磁性体305以及所述第二磁性体306的磁性大小及磁极方向,使得所述不锈钢303的表面以及所述支撑机构304的表面形成多个微小磁畴。此时,每一所述第一磁性体305靠近所述支撑机构304的一面3051与每一所述第二磁性体306靠近所述不锈钢层303的一面3061同级相排斥,并形成相互之间的排斥力。此排斥力在所述可折叠显示装置处于弯折状态时能有效减缓应力集中,有效提升了所述可折叠显示装置的使用寿命;此排斥力在所述可折叠显示装置处于展平状态时使所述可折叠显示装置的弯折区域具有一定的挺性,解决了按压下陷的问题。
如图4A、图4B及图4C所示,分别为本申请可折叠显示装置中柔性屏与支撑机构之间相互贴附的两层表面上的三个图案示意图。其中,多个所述第一磁性体105(305)沿着所述不锈钢层103(303)靠近所述支撑机构104(304)一侧的表面呈图案化分布,多个所述第二磁性体106(306)沿着所述支撑机构104(304)靠近所述不锈钢层103(303)一侧的表面呈图案化分布,所述图案化分布的图案为双I字型或X字型或等腰梯形。
由于所述支撑机构104(304)在反复弯折过程中两材料表面磁场强度不断变化,会引起所述不锈钢层103(303)与下方所述支撑机构104(304)的贴合对位精度发生变化。为了解决这种问题,在所述不锈钢层103(303)的表面和所述支撑机构104(304)的表面设计一定的图案化结构,使得多个所述第一磁性体105(305)以及多个所述第二磁性体106(306)沿着该图案化分布;在所述可折叠显示装置在展平和折叠过程中,在磁场强度改变的情况下仍有较高的对位精度,可避免柔性屏在反复弯折过程中的错位现象,提高整个所述可折叠显示装置的可靠性。
本申请所提供的可折叠显示装置,应用于OLED领域。在柔性屏与支撑机构之间不采用光学导电胶进行贴合,可以减少动态弯折过程中柔性屏所受到的拉扯,避免了应力集中现象,可提高柔性屏的使用寿命。同时,由于没有使用光学胶贴合,展平状态通过加大磁力使得柔性屏与支撑机构很好粘接在一起,解决了按压下陷及弯折前后出现的波浪起伏问题,能有效提升用户体验,增加产品的竞争力。此外,此结构设计较为简单,有效减少了机械结构的使用,有效的缩短了柔性OLED模组结构的开发周期。优选的,其他的部分膜层可以采用OCA胶材进行贴合,从而降低膜层弯折面的拉应力,防止光学器件的损伤。
本申请的有益效果为:本申请所提供的可折叠显示装置,在柔性屏与支撑机构之间采用磁性材料进行贴合,减缓了柔性屏处于动态弯折状态时的应力集中状况,提高了可折叠显示装置的使用寿命。
综上所述,虽然本申请已以优选实施例揭露如上,但上述优选实施例并非用以限制本申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
