Description

本申请涉及显示技术领域,尤其涉及一种柔性显示模组和电子装置。
背景技术
随着显示技术的发展,柔性显示越来越被人们喜爱,柔性显示因能实现折叠式显示,从而可以解决不易携带等问题。但折叠式显示装置在折叠时,柔性显示屏的折叠部的曲率半径接近该柔性显示屏的临界曲率半径,甚至小于该柔性显示屏的临界曲率半径,使柔性显示屏产生较大的内应力。而为了减小柔性显示屏弯折时产生的内应力,可使柔性显示屏发生直线滑动来补偿其在弯折区的形变。然而柔性显示屏弯折时产生的位移补偿势必会导致折叠式显示装置的边框处出现缝隙(Gap),影响主观感受和用户体验。

请参照图1和图2,图1为本申请实施例提供的柔性显示模组在展平状态时的一种剖面结构示意图,图2为图1中的柔性显示模组弯折时的一种剖面结构示意图。所述柔性显示模组100包括支撑构件10、柔性显示面板20、伸缩构件30以及控制机构40。所述柔性显示面板20包括主显示屏21,所述主显示屏21位于所述支撑构件10上,且所述主显示屏21具有至少一个弯折区BA,所述主显示屏21在所述弯折区BA能够弯折或折叠,进而使得所述柔性显示模组100能够实现弯折或折叠,如此可使所述柔性显示模组100占用更小的空间,以便于携带。
具体地,所述主显示屏21位于所述支撑构件10上,所述主显示屏21包括有机发光二极管显示(Organic Light Emitting Display,OLED)面板,则所述主显示屏21可包括柔性衬底、依次层叠设置在所述柔性衬底上的驱动电路层、发光功能层、封装层等,可以理解地,本申请的所述主显示屏21可包括常规OLED的各功能结构,在此不再赘述。因所述OLED面板具备柔性、可穿戴等优点,故所述主显示屏21能够进行弯折、折叠、卷曲,进而实现所述柔性显示模组100的可弯折、可折叠、可卷曲。
所述支撑构件10用于支撑所述主显示屏21,则所述主显示屏21位于所述支撑构件10上,可以理解为所述主显示屏21位于所述支撑构件10的上表面,以实现所述支撑构件10的支撑功能。可选地,所述支撑构件10包括第一支撑部11和第二支撑部12,在对应所述弯折区BA的位置,所述第一支撑部11和所述第二支撑部12活动连接。可选地,通过在所述弯折区BA设置铰链等转动机构使所述第一支撑部11和所述第二支撑部12通过铰链转动连接。当所述柔性显示模组100用于手机等电子装置时,所述支撑构件10可为手机的中框。
所述主显示屏21包括展平状态和弯折状态,当所述支撑构件10处于第一位置时,所述主显示屏21展平;当所述支撑构件10处于第二位置时,所述主显示屏21在对应所述弯折区BA的位置弯折。其中所述第一位置是指所述支撑构件10处于展平状态,此时所述第一支撑部11和所述第二支撑部12在同一水平方向上,以共同支撑所述主显示屏21;所述第二位置是指所述支撑构件10沿着所述弯折区BA的弯折方向弯折,也即所述第一支撑部11和所述第二支撑部12发生相对转动,以实现所述柔性显示模组100的弯折或折叠,此时所述主显示屏21随着所述支撑构件10的弯折也沿着所述弯折区BA的弯折方向弯折,使所述主显示屏21处于弯折状态。而且所述主显示屏21会在所述弯折区BA的位置发生形变,为了减小所述弯折区BA形变应力,所述主显示屏21的至少一端会相对所述支撑构件10发生直线滑动产生位移,本申请实施例以所述主显示屏21对应所述第二支撑部12的一端发生位移为例说明。
可以理解的是,所述主显示屏21滑动产生的位移会使得所述主显示屏21与边框之间产生缝隙(Gap),而缝隙处不会显示,影响主观感受和用户体验。
为此,本申请实施例在位于所述支撑构件10远离所述弯折区BA的一端设置伸缩构件30,以补偿所述主显示屏21在弯折状态产生的位移。其中在沿所述主显示屏21产生位置方向上,所述支撑构件10的长度小于所述主显示屏21的长度,且所述主显示屏21与所述支撑构件10的长度差大于或等于所述主显示屏21在弯折状态产生的位移,以使所述伸缩构件30在做伸缩运动时,不会被所述支撑构件10干涉,进而能够完全补偿所述主显示屏21在弯折状态产生的位移。
所述伸缩构件30包括支撑件31,所述支撑件31能够相对于所述支撑构件10进行伸缩运动。具体而言,当所述主显示屏21处于展平状态时,所述支撑件31伸出所述支撑构件10,所述主显示屏21位于所述支撑构件10及所述支撑件31上,如图1所示;当所述主显示屏21处于弯折状态时,至少部分所述支撑件31收缩进所述支撑构件10,如图2所示。可选地,所述支撑件31可由金属、塑料等材料形成的板块,在所述主显示屏21处于展平状态时,所述支撑件31伸出所述支撑构件10以和所述支撑构件10一块支撑所述主显示屏21。
可选地,所述支撑件31可活动地连接于所述控制机构40,所述控制机构40用于控制所述伸缩构件30的所述支撑件31相对于所述支撑构件10进行伸缩运动。可选地,所述控制机构40包括电机等动力装置,所述控制机构40可固定地连接于所述支撑构件10,所述控制机构40给所述伸缩构件30提供动力并精准控制所述支撑件31的位移。可选地,所述柔性显示模组100还包括开关构件50,所述开关构件50设置于所述支撑构件10上,所述开关构件50用于开启或关闭所述控制机构40对所述伸缩构件30的控制。
进一步地,所述伸缩构件30还包括垂直连接于所述支撑件31的装饰件32,所述主显示屏21的远离所述弯折区BA的一端面向所述装饰件32,所述装饰件32与所述主显示屏21的远离所述弯折区BA的所述一端相贴。所述主显示屏21和所述支撑构件10在所述装饰件32所在平面上的正投影均落在所述装饰件32的界面内,使得所述装饰件32能够遮挡所述主显示屏21以及所述支撑构件10远离所述弯折区BA的一端的侧面,也即所述装饰件32相当于所述柔性显示模组100的一边框,用以保护所述主显示屏21和所述支撑构件10。
可选地,所述装饰件32和所述支撑件31的材料可以相同或者不同。比如所述装饰件32也是由金属、塑料等材料形成的板块或壳体等。
所述装饰件32和所述支撑件31在所述控制机构40的作用下同步运动。具体而言,所述装饰件32和所述支撑件31均与所述控制机构40活动连接,比如所述装饰件32和所述支撑件31均可通过轴承与所述控制机构40活动连接,所述控制机构40通过控制轴承的行程以精准的控制所述装饰件32和所述支撑件31相对所述主显示屏21以及所述支撑构件10发生相对滑动,以补偿所述主显示屏21在弯折状态时产生的位移。
下面将具体阐述如何补偿所述主显示屏21由展平状态切换到弯折状态时产生的位移:
如图1所示,当所述主显示屏21处于展平状态时,所述支撑件31伸出所述第二支撑部12,所述主显示屏21位于所述支撑构件10及所述支撑件31上,此时所述支撑构件10和所述支撑件31一块支撑所述主显示屏21。所述装饰件32位于所述主显示屏21远离所述弯折区BA的一端,且所述装饰件32与所述主显示屏21的远离所述弯折区BA的所述一端相贴,也即在所述主显示屏21处于展平状态时,所述装饰件32与所述主显示屏21之间不存在缝隙(Gap)。
当所述主显示屏21沿着所述弯折区BA的弯折方向弯折时,位于所述第二支撑部12以及所述支撑件31上的所述主显示屏21部分会相对所述第二支撑部12发生相对滑动,使得所述主显示屏21朝着远离所述装饰件32的方向滑动。而在所述主显示屏21滑动的过程中,所述控制机构40控制所述支撑件31和所述装饰件32同步滑动,具体而言,所述支撑件31朝着所述第二支撑部12的方向滑动,以缩进所述第二支撑部12内;同时所述装饰件32也朝着所述第二支撑部12的方向滑动,如此通过所述支撑件31和所述装饰件32的滑动位移来补偿所述主显示屏21的滑动位移,以保持所述装饰件32与所述主显示屏21的远离所述弯折区BA的所述一端始终相贴,形成如图2所示的主显示屏21弯折后的结构示意图。
当所述主显示屏21处于弯折状态时,所述支撑件31完全缩进所述第二支撑部12内,所述装饰件32与所述主显示屏21的远离所述弯折区BA的所述一端仍旧相贴,使得所述主显示屏21与所述装饰件32之间依然不存在缝隙(Gap)。从而解决了现有折叠式显示装置弯折时边框处出现缝隙的问题。同时通过设置伸缩构件30还使得柔性显示模组100无需设置较大边框来匹配主显示屏21的位移,进而能够实现窄边框。
当所述主显示屏21由弯折状态回复到展平状态时,所述控制机构40控制所述支撑件31和所述装饰件32朝着远离所述第二支撑部12的方向滑动,以释放出所述主显示屏21的位移空间,此时所述主显示屏21朝着所述装饰件32的方向滑动,形成如图1所示的主显示屏21的展平状态示意图。
在一种实施例中,请参照图3和图4,图3为本申请实施例提供的柔性显示模组在展平状态时的另一种剖面结构示意图,图4为图3中的柔性显示模组弯折时的一种剖面结构示意图。与上述实施例不同的是,所述柔性显示模组101中的所述柔性显示面板20还包括位于所述支撑件31上方且连接于所述控制机构40的副显示屏22,所述副显示屏22的远离弯折区BA的一端面向所述装饰件32,当所述主显示屏21处于弯折状态时,所述支撑件31部分收缩进所述支撑构件10。所述副显示屏22可活动地连接于所述控制机构40,所述控制机构40能够控制所述副显示屏22上升、下降、向左移动或向右移动。而且所述副显示屏22还在所述控制机构40的控制下与所述伸缩构件30联动,以补偿所述主显示屏21弯折时产生的位移。可选地,所述副显示屏22包括液晶显示面板、OLED显示面板等类型的显示面板。
下面将具体阐述所述副显示屏22和所述伸缩构件30如何补偿所述主显示屏21由展平状态切换到弯折状态时产生的位移:
具体地,如图3所示,当所述主显示屏21处于展平状态时,所述副显示屏22位于所述支撑构件10与所述装饰件32之间,且位于所述支撑件31上方。此时所述副显示屏22位于所述支撑件31和所述主显示屏21之间,所述支撑件31支撑所述副显示屏22,所述副显示屏22和所述支撑构件10一块支撑所述主显示屏21。所述支撑件31和所述装饰件32还均连接于所述控制机构40,其中所述装饰件32位于所述主显示屏21以及所述副显示屏22远离所述弯折区BA的一端,且所述装饰件32与所述主显示屏21的远离所述弯折区BA的所述一端相贴,也即在所述主显示屏21处于展平状态时,所述装饰件32与所述主显示屏21之间不存在缝隙(Gap)。当然可选地,所述装饰件32还可与所述副显示屏22远离所述弯折区BA的一端相贴,但所述副显示屏22在沿所述支撑构件10长度方向上的长度要小于所述主显示屏21弯折时产生的滑动位移距离。
当所述主显示屏21沿着所述弯折区BA的弯折方向弯折时,位于所述第二支撑部12以及所述副显示屏22上的所述主显示屏21部分会相对所述第二支撑部12发生相对滑动,使得所述主显示屏21朝着远离所述装饰件32的方向滑动。而在所述主显示屏21的滑动结束后,所述控制机构40控制所述副显示屏22朝着远离所述支撑件31的方向滑动,使所述副显示屏22和所述主显示屏21平齐且相接,以填补在所述主显示屏21弯折时产生的位移内。具体而言,所述控制机构40控制所述副显示屏22上升到与所述主显示屏21相同的平面,并使所述副显示屏22靠近所述弯折区BA的一端与所述主显示屏21远离所述弯折区BA的一端相贴,且使所述副显示屏22与所述主显示屏21的上表面平齐。
同时所述控制机构40还控制所述伸缩构件30滑动,以微调所述装饰件32与所述副显示屏22之间的距离,具体而言,所述控制机构40控制所述装饰件32朝着所述副显示屏22的方向滑动,使所述装饰件32与所述副显示屏22的远离所述弯折区BA的一端相贴,当然地,随着所述装饰件32的滑动,所述支撑件31也会朝着所述第二支撑部12的方向滑动,使部分所述支撑件31收缩进所述第二支撑部12内,形成如图4所示的主显示屏21弯折后的结构示意图。
如图4所示,当所述主显示屏21处于弯折状态时,所述支撑构件被所述主显示屏21包覆,使所述柔性显示模组101形成外折。此时所述支撑件31部分缩进所述第二支撑部12内,所述副显示屏22和所述主显示屏21平齐且相接,且所述装饰件32与所述副显示屏22的远离所述弯折区BA的一端相贴,如此通过所述副显示屏22和所述伸缩构件30的配合以补偿所述主显示屏21滑动产生的位移。从而解决了现有折叠式显示装置弯折时边框处出现缝隙的问题。同时通过设置伸缩构件30和所述副显示屏22还使得柔性显示模组100无需设置较大边框来匹配主显示屏21的位移,进而能够实现窄边框。
当所述主显示屏21由弯折状态回复到展平状态时,所述控制机构40控制所述副显示屏22朝着所述支撑件31的方向滑动至所述支撑件31上方,同时所述控制机构40还控制所述支撑件31和所述装饰件32朝着远离所述第二支撑部12的方向滑动,以释放出所述主显示屏21的位移空间,此时所述主显示屏21朝着所述装饰件32的方向滑动,形成如图3所示的主显示屏21的展平状态示意图。其他说明请参照上述实施例,在此不再赘述。
可以理解的是,在另一种实施例中,作为上述实施例的变形,所述副显示屏22还可直接与所述支撑件31固定连接,所述控制机构40控制所述支撑件31滑动,所述支撑件31的滑动带动所述副显示屏22的滑动。当所述主显示屏21处于弯折状态时,所述支撑件31带动所述副显示屏22上升到与所述主显示屏21平齐且相接的位置,此时所述支撑件31还能起到支撑所述副显示屏22的作用。
或者,所述副显示屏22还可与所述支撑件31活动连接,比如所述伸缩构件30还包括位于所述支撑件31上的弹性件(图未示),所述副显示屏22通过所述弹性件与所述支撑件31连接。当所述主显示屏21由展平状态切换为弯折状态时,所述支撑件31部分收缩进所述支撑构件10,所述副显示屏22通过所述弹性件弹出到与所述主显示屏21平齐的位置,然后通过所述控制机构40控制所述伸缩构件30滑动,以微调所述主显示屏21、所述副显示屏22以及所述装饰件32之间的距离。当所述主显示屏21由弯折状态切换为展平状态时,所述弹性件收缩以拉回所述副显示屏22。
在一种实施例中,请结合参照图3至图5,图5为图3中的柔性显示模组弯折时的另一种剖面结构示意图。与上述实施例不同的是,所述柔性显示模组101为内折,具体而言,当所述主显示屏21处于展平状态时,所述副显示屏22位于所述支撑构件10与所述装饰件32之间,即所述副显示屏22位于所述主显示屏21面向所述支撑构件10的一侧,且还位于所述第二支撑部12面向所述装饰件32的一侧,如图3所示。当所述主显示屏21处于弯折状态时,所述主显示屏21被所述支撑构件10包覆,以实现所述柔性显示模组101的内折,此时所述副显示屏22还位于所述第二支撑部12与所述装饰件32之间,且所述副显示屏22远离所述弯折区BA的一端与所述主显示屏21远离所述弯折区BA的一端平齐,如图5所示。
具体地,当所述主显示屏21由展平状态切换为弯折状态时,所述主显示屏21对应所述第二支撑部12的一端会发生直线滑动产生位移。此时所述控制机构40控制所述副显示屏22和所述伸缩构件30联动,具体而言,所述副显示屏22朝着所述第二支撑部12的方向滑动,使所述副显示屏22远离所述弯折区BA的一端与所述主显示屏21远离所述弯折区BA的一端平齐;所述伸缩构件30的所述支撑件31部分收缩进所述第二支撑部12内,所述装饰件32同步朝着所述主显示屏21和所述副显示屏22移动,并与所述主显示屏21和所述副显示屏22远离所述弯折区BA的一端相贴,以填补所述主显示屏21滑动产生的位移。
可以理解的是,在所述主显示屏21处于弯折状态时,所述副显示屏22位于所述主显示屏21面向所述第二支撑部12的一侧,并与所述第二支撑部12远离所述主显示屏21的一侧表面基本平齐。所述副显示屏22可将摄像功能、天气、时钟等功能置入其中,以增加所述柔性显示模组101的趣味性。当然地,所述副显示屏22远离所述主显示屏21的一侧还存在所述支撑件31,而为了使所述柔性显示模组101处于内折时所述副显示屏22能够显示,所述支撑件31在对应所述副显示屏22的位置设置凹槽,所述凹槽裸露出所述副显示屏22的显示面。其他说明请参照上述实施例,在此不再赘述。
在一种实施例中,请结合参照图1至图7,图6为本申请实施例提供的柔性显示模组在展平状态时的又一种剖面结构示意图,图7为图6中柔性显示模组在弯折状态时的一种剖面结构示意图。与上述实施例不同的是,在本实施例的柔性显示模组102中,所述主显示屏21在展平状态时,所述副显示屏22位于所述主显示屏21远离所述弯折区BA的一端,并位于所述主显示屏21和装饰件32之间,且所述副显示屏22的上表面与所述主显示屏21的上表面平齐,如图6所示。当所述主显示屏21处于弯折状态时,所述支撑构件10被所述主显示屏21包覆,以实现所述柔性显示模组102的外折,此时所述副显示屏22仍然位于所述主显示屏21远离所述弯折区BA的一端,并位于所述主显示屏21和装饰件32之间,且所述副显示屏22的上表面与所述主显示屏21的上表面平齐,使所述副显示屏22与所述主显示屏21平齐且相接,如图7所示。
具体地,当所述主显示屏21由展平状态切换为弯折状态时,所述主显示屏21对应所述第二支撑部12的一端会发生直线滑动产生位移。此时所述控制机构40控制所述副显示屏22和所述伸缩构件30联动,使所述副显示屏22和所述伸缩构件30均朝着所述主显示屏21滑动,具体而言,所述副显示屏22朝着所述主显示屏21的方向滑动,使所述副显示屏22靠近所述弯折区BA的一端与所述主显示屏21远离所述弯折区BA的一端相接,且所述副显示屏22和所述主显示屏21的上表面保持平齐;所述伸缩构件30的所述支撑件31部分收缩进所述第二支撑部12内,所述装饰件32同步朝着所述副显示屏22的方向滑动,并与所述副显示屏22远离所述弯折区BA的一端相贴,以填补所述主显示屏21产生的位移。其他说明请参照上述实施例,在此不再赘述。
可以理解的是,在另一种实施例中,请结合参照图6和图5,与上述实施例不同的是,图6所示的所述柔性显示模组102还可以内折,内折后形成如图5所示的所示主显示屏21在弯折状态时的结构示意图。具体而言,当所述主显示屏21由展平状态切换为弯折状态时,所述主显示屏21对应所述第二支撑部12的一端会发生直线滑动产生位移。此时所述控制机构40控制所述副显示屏22下降,以滑动到所述主显示屏21面向所述第二支撑部12的一侧,并使所述副显示屏22远离所述弯折区的一端与所述主显示屏21远离所述弯折区的一端平齐,以使得所述柔性显示模组102在内折时所述副显示屏22还可用于显示。同时所述控制机构40还控制所述伸缩构件30朝着所述主显示屏21的方向滑动,具体而言,所述支撑件31随着所述副显示屏22下降,并朝着所述第二支撑部12的方向滑动,以部分伸缩进所述第二支撑部12内;所述装饰件32朝着所述副显示屏22的方向滑动,以使所述装饰件32与所述副显示屏22远离所述弯折区的一端以及所述主显示屏21远离所述弯折区的一端相贴,以填补所述主显示屏21滑动产生的位移。其他说明请参照上述实施例,在此不再赘述。
在一种实施例中,本申请实施例还提供一种电子装置,其包括壳体和柔性显示模组,所述壳体形成有容纳腔,所述柔性显示模组装配在所述容纳腔内,其中所述柔性显示模组包括前述实施例其中之一的柔性显示模组。所述电子装置包括手机、电视、平板等电子产品。
根据上述实施例可知:
本申请提供一种柔性显示模组和电子装置;该柔性显示模包括支撑构件、柔性显示面板、伸缩构件以及控制机构,柔性显示面板包括主显示屏,所述主显示屏位于所述支撑构件上,且所述主显示屏具有弯折区。伸缩构件位于所述支撑构件远离所述弯折区的一端,所述伸缩构件包括支撑件,所述支撑件能够相对于所述支撑构件进行伸缩运动。控制机构与所述伸缩构件连接,所述控制机构用于控制所述伸缩构件相对于所述支撑构件进行伸缩运动。所述主显示屏包括展平状态和弯折状态,当所述主显示屏处于展平状态时,所述支撑件伸出所述支撑构件,所述主显示屏位于所述支撑构件及所述支撑件上;当所述主显示屏处于弯折状态时,至少部分所述支撑件收缩进所述支撑构件。本申请通过伸缩构件的伸缩运动来补偿主显示屏的位移,避免了主显示屏弯折时由于位移而出现的缝隙,从而解决了现有折叠式显示装置弯折时边框处出现缝隙的问题。同时通过设置伸缩构件还使得柔性显示模组无需设置较大边框来匹配主显示屏的位移,进而能够实现窄边框。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
