OLED技术被称为下一代显示技术,随着OLED显示技术的发展日趋成熟,广大消费者体验到了OLED显示与传统LCD显示的巨大差异,随之而来的是OLED消费市场的迅速增长。由于OLED自发光的特性,使得响应时间短、高对比度、广视角、广色域、显示面板轻薄化、可弯折性等特点得以实现。特别是OLED显示面板的可弯折性,给消费者带来了颠覆性的概念,因此Flexible(可弯折)OLED近年来是行业发展的主流。
以往大多数关于柔性显示装置采用折叠式结构,即将整个用来承载柔性显示面板的中框划分为几个组装部分,通过一个或多个铰接组件,将各个组装部分连接起来。利用铰接组件的可转动结构,使得相邻两个组装部件之间能够折叠,使得柔性显示装置的尺寸缩小,方便携带。但是由于铰链的存在,使得显示装置在完全展开时,相邻两组装部件之间存在孔隙,无法将整个柔性显示面板全部支撑起来,部分柔性显示面板处于悬空状态。如此,柔性显示面板容易产生皱折,影响显示效果;同时,用户在进行指触控时,也会由于没有底部支撑,容易对柔性显示面板造成伤害。
人们希望找到一种适用于柔性显示面板展开或折合的显示装置。
发明内容

其中,所述第一支撑件、第二支撑件顶面分别设有第一限位槽、第二限位槽,用于对所述柔性显示面板形成限位。
其中,所述第一支撑件朝所述第二支撑件方向、沿所述第三支撑件顶面延 伸第一压持部;所述第二支撑件朝所述第一支撑件方向、沿所述第三支撑件顶面延伸第二压持部;所述第一压持部、第二压持部将所述第三支撑件夹持于由所述第一支撑件、第二支撑件和所述基台围成的容置空间内。

通过结合附图进行的以下描述,本发明的实施例的上述和其它方面、特点和优点将变得更加清楚,附图中:
图1是本发明实施例显示装置的结构示意图。
图2是本发明实施例显示装置另一结构剖面示意图。
图3是图2中A区域的放大图。
图4是本发明实施例显示装置又一结构剖面示意图。
具体实施方式
以下,将参照附图来详细描述本发明的实施例。然而,可以以许多不同的形式来实施本发明,并且本发明不应该被解释为限制于这里阐述的具体实施例。相反,提供这些实施例是为了解释本发明的原理及其实际应用,从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
如图1所示,本发明提供一种显示装置,其包括柔性显示面板200以及用于支撑所述柔性显示面板200的承载组件100。其中,所述承载组件100包括:基台40、第一支撑件10、第二支撑件20和第三支撑件30。结合图2可知,第一支撑件10、第二支撑件20能够在基台40上作往返运动,呈现相互接触或相互远离的状态。通过第一支撑件10、第二支撑件20相互远离或相互接触的状态变换,第三支撑件30从第一支撑件10、第二支撑件20之间抬升或下降,实现承载组件100具有不同大小的承载平面,使柔性显示面板200能够随承载平面的大小实现缩放的功能。
具体地,如图1所示,第一支撑件10、第二支撑件20呈镜像对称设置于所述基台40上;当所述第一支撑件10、第二支撑件20相接触时,第一支撑件10、第二支撑件20的顶面位于同一水平面上,所述第一支撑件10、第二支撑件20相互拼接构成用于承载所述柔性显示面板200的第一平面101。
结合图2所示,为了实现第一支撑件10、第二支撑件20是能够滑动的,所述承载组件100还包括有至少一组滑动导轨50,所述第一支撑件10、第二支撑件20通过所述滑动导轨50与所述基台40连接;使得所述第一支撑件10、第二支撑件20能沿所述滑动导轨50作往返运动,实现相互接触、相互远离等的不同位置状态。
为了对第一支撑件10、第二支撑件20的滑动范围进行限制,所述第一支撑件10、第二支撑件20的底部对应于所述滑动导轨50两端还设有第一限位件11、第二限位件21,用于对所述第一支撑件10、第二支撑件20相互远离时形成最大移位限位。具体地,当第一支撑件10、第二支撑件20相互远离,逐渐到达滑动导轨50的两端,第一限位件11、第二限位件21分别卡设于滑动导轨50端部上,使得第一支撑件10、第二支撑件20无法继续远离而到达最大远离 移位。当然,本领域技术人员可知,为了让第三支撑件30能抬升至第一平面101上,第一支撑件10、第二支撑件20之间至少存在一个距离不小于所述第三支撑件30的宽度,容纳第三支撑件30卡设于第一支撑件10、第二支撑件20之间。
所述第一支撑件10、第二支撑件20外侧分别设有第一弧形侧壁12、第二弧形侧壁22。当柔性显示面板200在弹性件带动下与第一支撑件10、第二支撑件20发生相对位移时,弧形的侧壁设计可使得柔性显示面板能够实现流畅滑移。
进一步地,结合图2和图3所示,所述第一支撑件10、第二支撑件20底部分别设置有第一弹性件17、第二弹性件27,所述柔性显示面板200两端分别沿所述第一弧形侧壁12、第二弧形侧壁22延展至所述第一支撑件10、第二支撑件20底部、并分别与第一弹性件17、第二弹性件27连接。优选地,本实施例的第一弹性件17、第二弹性件27可例如为矩形弹簧,通过弹簧的弹性形变势能使显示面板保持平整的状态。
具体地,柔性显示面板200是通过第一弹性件17、第二弹性件27绕设于所述第一支撑件10、第二支撑件20上。当所述第一支撑件10、第二支撑件20相互接触,第一弹性件17、第二弹性件27处于张紧的拉伸态势,第一弹性件17、第二弹性件27共同作用于柔性显示面板上,使得柔性显示面板能保持张紧、平整的状态,确保显示品质;当所述第一支撑件10、第二支撑件20逐渐相互远离,所述第一弹性件17、第二弹性件27随着所述第一支撑件10、第二支撑件20逐渐远离也相互分离,但仍分别处于张紧的拉伸态势,使所述柔性显示面板200是始终保持张紧、平整的状态。
为了使柔性显示面板200的位置在滑移过程中保持相对稳定,所述第一支撑件10、第二支撑件20顶面分别设有第一限位槽13、第二限位槽23,用于对所述柔性显示面板200形成限位,使得柔性显示面板在滑移的过程中不会左右晃动。
结合图1、图2所示,第三支撑件30呈梯形,其设置于所述基台40和所述第一平面101之间。所述第三支撑件30卡设于所述第一支撑件10、第二支撑件20之间,且所述第三支撑件30通过一起弹件31(结合图4所示)与所述 基台40连接。优选地,所述起弹件31可例如为四个弹簧。
为了获得稳定的第一平面101,所述第一支撑件10朝所述第二支撑件20方向、沿所述第三支撑件30顶面延伸第一压持部14;所述第二支撑件20朝所述第一支撑件10方向、沿所述第三支撑件30顶面延伸第二压持部24。利用所述第一压持部14、第二压持部24将所述第三支撑件30夹持于由所述第一支撑件10、第二支撑件20和所述基台40围成的容置空间内。
为了配合第三支撑件30的形状,所述第一支撑件10、第二支撑件20朝向所述第三支撑件30的侧面分别设有第一对位斜面16、第二对位斜面26,用于对所述第三支撑件30容置于所述容置空间时形成限位。
优选地,为了实现第三支撑件30顺利抬升或下降,所述第一压持部14、第二压持部24朝向所述第三支撑件30的侧部分别设有第一限位斜面15、第二限位斜面25,所述第三支撑件30两侧部分别设有与所述第一限位斜面15、第二限位斜面25的造型对应的导向斜面32。
结合图4所示,当所述第一支撑件10、第二支撑件20从相互接触逐渐相远离时,第一压持部14、第二压持部24逐渐分离,所述第三支撑件30受到的向下压力逐渐减少,且在所述起弹件31作用下逐渐抬升、最终达到原第一平面101上,并与所述第一支撑件10、第二支撑件20共同拼接成用于承载所述柔性显示面板200的第二平面102。此时,起弹件31处于松弛状态。第一限位斜面15、第二限位斜面25的形状也能够与所述导向斜面32的形状对应,使得第三支撑件30能够与第一支撑件10、第二支撑件20之间形成“无缝拼接”。在第一支撑件10、第二支撑件20相互远离过程中,柔性显示面板200“隐藏”于第一支撑件、第二支撑件底部的部分,逐渐被拉伸至第一弧形侧壁12、第二弧形侧壁22上、甚至能够到达第一支撑件、第二支撑件的顶面。第一弹性件17、第二弹性件27同时被拉伸,保持柔性显示面板始终贴服地在第一支撑件、第二支撑件上滑移。待第二平面102组合完成,由第一支撑件10、第二支撑件20、第三支撑件30承担支撑整个柔性显示面板200的任务,使得柔性显示面板200能够获得全面、均匀有效的支撑效果,确保柔性显示面板的使用品质、功能得到保障。此时,可看到完全展开后的柔性屏幕,实现柔性屏幕在尺寸的延展。
当所述第一支撑件10、第二支撑件20从相互远离的状态逐渐相互靠近时,第一限位斜面15、第二限位斜面25的斜面造型能够向导向斜面32形成下压作用力,迫使第三支撑件32下降,起弹件31逐渐压缩,最终所述第三支撑件32在所述导向斜面32导向下沿所述第一限位斜面15、第二限位斜面25下降、返回至第一支撑件、第二支撑件和基台围成的容置空间内。此时,第一支撑件10、第二支撑件20相互接触,恢复第一平面101。在第一支撑件10、第二支撑件20相互靠近过程中,柔性显示面板200“裸露”于第一弧形侧壁12、第二弧形侧壁22或第一支撑件10、第二支撑件20的顶部分,逐渐被第一弹性件17、第二弹性件27牵引恢复至第一支撑件、第二支撑件底面。第一弹性件17、第二弹性件27保持柔性显示面板始终贴服地在第一支撑件、第二支撑件上滑移。待第一平面102组合完成,由第一支撑件10、第二支撑件20承担支撑整个柔性显示面板200的任务,此时,可看到完全回缩后的柔性屏幕,实现柔性屏幕在尺寸的缩小,满足便携的功能。
本发明提供的显示装置,不同于现有的折叠结构,利用可伸缩的承载组件结构承载柔性显示面板,实现柔性显示面板的可伸缩折叠、精致便携的功能,同时,能够全面、稳定支撑整个柔性显示面板,无悬空状态,确保显示品质和器件功能获得最佳效果。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
