Description

柔性显示装置以及电子设备 技术领域
本发明属于显示技术领域，尤其涉及柔性显示装置以及具有该柔性显示装置的电子设备。
 背景技术
目前，常见的显示装置具有电视、电脑和手机等使用的显示屏，该显示屏可以是液晶显示屏（Liquid Crystal Display，简称LCD）或者发光二极管（Light emitting diode，简称LED）显示屏等。这些显示屏不可避免地有着一定的重量、厚度和体积，并被固定在某个地方。而在此基础上，三维显示或者触控显示等的应用，给用户带来全新的感受和体验。与上述显示装置相对的称之为柔性显示装置，柔性显示装置的核心部件是柔性显示屏，柔性显示屏因轻薄、可弯曲等特征，使其具有巨大的应用潜力。
通常，柔性显示装置是由柔性材料制成，可变形、可弯曲的显示装置，具有低功耗、体积小及直接可视柔性等特点。一般而言，采用驱动IC点亮并驱动柔性显示屏及柔性显示产品，常见的做法是：在柔性薄膜的TCP及COP薄膜上粘贴驱动IC后，绑定在面板上使用。如图1至图4所示的驱动IC3a的安装结构示意图，其中，图1至图3为驱动IC3a设置于柔性显示面板1a的其中一侧边；图4为驱动IC3a设置于柔性显示面板1a的相邻两侧边。可以看出，驱动IC3a通常采用了沿柔性显示面板1a的边缘方向设置，由于驱动IC3a具有一定的几何长度，按照现有的安装方法，虽然能简化IC电路的布线，但是设置了驱动IC3a的柔性显示面板1a随着自身发生弯曲，即使驱动IC3a也可以随之弯曲，但如果弯曲的曲率和弯曲力变大，在发生弯曲的过程中，会出现驱动IC3a发生破裂和/或者断裂从而导致破损的问题。

本体部21，包括元件设置区域22及预留区域23；
连接部25，沿所述预留区域23朝向所述柔性显示面板10突出延伸并连接于所述柔性显示面板10；
其中，所述本体部21、所述连接部25与所述柔性显示面板10形成间隔空间12；
驱动IC30，电性安装于所述元件设置区域22。
本发明实施例提供的柔性显示装置通过在所述柔性电路板20上设置预留区域23并使得所述本体部21与所述柔性显示面板10之间形成间隔空间12，并将所述驱动IC30设置于元件设置区域22，以使所述柔性显示面板10在弯曲变形时对设置于所述柔性电路板20上的驱动IC30无影响，从而避免对所述驱动IC30造成折断或者断裂等破坏现象。
在该实施例中，由于本体部21与柔性显示面板10之间存在间隔空间12并在柔性电路板20上设置有预留区域23，当所述柔性显示面板10沿其任意侧边弯曲时，所述元件设置区域22连同所述驱动IC30不参与到弯曲变形过程，从而所述驱动 IC30不影响所述柔性显示面板10的弯曲变形。
在该实施例中，所述预留区域23、所述元件设置区域22和所述连接部25为一体化设置。
在该实施例中，所述柔性显示面板10为OLED柔性显示屏或者柔性触控显示屏。
在该实施例中，所述柔性显示面板10连同所述柔性电路板20可以沿所述柔性显示面板10的长边或者宽边所在方向发生弯曲变形。
请参照图5至图7，进一步地，所述连接部25连接于所述柔性显示面板10的连接侧边14。该连接侧边14不限于物理定位连接，包括连接部25与柔性显示面板10的电性连接后由连接侧边14延伸出来的边侧定义。可以理解，所述连接部25沿所述预留区域23延伸，并连接于所述柔性显示面板10的连接侧边14，所述连接部25所在平面与所述柔性显示面板10的显示面平行。
请参照图5，优选地，所述本体部21沿相对于所述连接侧边14的纵向方向分割为所述元件设置区域22及所述预留区域23。可以理解，在所述连接侧边14的纵向方向上，所述元件设置区域22与所述预留区域23并排设置，所述元件设置区域22与所述预留区域23的排布方向为所述连接侧边14的延伸方向，或者与所述连接侧边14的延伸方向之间形成夹角，该夹角0-180°且不为90°。
优选地，所述驱动IC30的设置方向与所述连接侧边14平行。在其他实施例中，所述驱动IC30的设置方向与上述连接侧边14垂直，或任意角度。

请参照图6，优选地，所述预留区域23包括所述贯穿区域230以及位于所述贯穿区域230和所述元件设置区域22之间的间隔区域232。所述预留区域23包括位于所述连接部25之背离所述连接侧边14一侧的贯穿区域230以及位于所述贯穿区域230和所述元件设置区域22之间的间隔区域232。可以理解，所述贯穿区域230、所述间隔区域232和所述元件设置区域22沿所述连接侧边14的延伸方向并排设置，且所述间隔区域232、所述贯穿区域230和所述连接部25构成一L型。当所述柔性显示面板10绕该连接侧边14发生弯曲变形时，由于间隔空间12可以使该元件设置区域22不参与到弯曲变形中，从而避免对驱动IC30的损坏，如图8所示。同样地，当所述柔性显示面板10绕该连接侧边14的相邻侧边发生弯曲变形时，所述连接部25和所述预留区域23参与弯曲变形，而由于预留区域23与元件设置区域22并排设置且为该间隔空间12的一围合侧，这样可以使该元件设置区域22不参与到弯曲变形中，从而避免对驱动IC30的损坏，如图9所示。
请参照图7，优选地，所述预留区域23包括位于所述连接部25之背离所述连接侧边14一侧的贯穿区域230以及位于所述贯穿区域230两侧的第一间隔区域234和第二间隔区域236。可以理解地，所述第一间隔区域234和所述第二间隔区域236位于所述贯穿区域230的两侧，这样，所述第一间隔区域234、所述贯穿区域230和所述第二间隔区域236与所述连接部25构成一T字型结构。所述连接部25和所述贯穿区域230的排布方向与所述第一间隔区域234、所述贯穿区域230和所述第二贯穿区域230的排布方向相互垂直，或者成一定夹角。当所述柔性显示面板10绕该连接侧边14发生弯曲变形时，由于间隔空间12可以使该元件设置区域22不参与到弯曲变形中，从而避免对驱动IC30的损坏。同样地，当所述柔性显示面板10绕该连接侧边14的相邻侧边发生弯曲变形时，由于间隔空间12及第一间隔区域234和第二间隔区域236可以使该元件设置区域22不参与到弯曲变形中，从而避免对驱动IC30的损坏。
