本申请提供一种可折叠显示装置。在本申请中,所述可折叠显示装置可以理解为显示区域能够折叠的装置。所述可折叠显示装置可以为手机、平板电脑、可穿戴设备等具有显示功能的电子产品,可实现大屏显示且方便携带。
在一些实施例中,所述可折叠显示装置包括柔性显示屏及承载组件。所述承载组件具有展平形态和折叠形态。所述承载组件展平时的形状可以有多种,例如矩形、圆形、六边形等。所述承载组件展开时具有长边方向和短边方向,短边方向与长边方向彼此垂直。以手机为例,所述承载组件展平时,可以大致呈矩形。所述承载组件的长边所在方向为长边方向,短边所在方向为短边方向。
所述承载组件包括沿长边方向依次连接的第一平面部、第一折弯部、第二平面部、第二折弯部及第三平面部。所述第一折弯部在所述长边方向的长度大于所述第二折弯部在所述长边方向的长度。所述第一平面部、所述第二平面部及所述第三平面部在所述长边方向上的长度可相同或不同。所述承载组件的各个部分在所述短边方向上的长度一致。所述承载组件变换形态时,所述第一平面部、所述第二平面部及所述第三平面部维持平面状态,所述第一折弯部在曲面与平面之间变化,所述第二折弯部在曲面与平面之间变化。

所述可折叠显示装置100可以为手机、平板电脑、可穿戴设备等具有显示功能的电子产品。本申请以所述可折叠显示装置100是手机为例进行说明。
请一并参阅图1至图3,所述可折叠显示装置100包括柔性显示屏1及承载组件2。所述承载组件2具有展平形态(如图1和图2所示)和折叠形态(如图3所示)。所述承载组件2处于展平形态时,对应于所述可折叠显示装置100的展平形态。所述承载组件2处于展平折叠时,对应于所述可折叠显示装置100的折叠形态。
所述承载组件展平2时的形状可以有多种,例如矩形、圆形、六边形等。所述承载组件2展开时具有长边方向和短边方向,短边方向与长边方向大致垂直。例如,所述承载组件2展平时,大致呈矩形。所述承载组件2的长边所在方向为长边方向X,短边所在方向为短边方向Y。
所述承载组件2包括沿长边方向X依次连接的第一平面部21、第一折弯部22、第二平面部23、第二折弯部24及第三平面部25。所述第一折弯部22在所述长边方向X的长度大于所述第二折弯部24在所述长边方向X的长度。所述第一平面部21、所述第二平面部23及所述第三平面部25在所述长边方向X上的长度可相同或不同。所述承载组件2的各个部分在所述短边方向Y上的长度一致。所述承载组件2变换形态时,所述第一平面部21、所述第二平面部23及所述第三平面部25维持平面状态,所述第一折弯部22弯折或展开,所述第二折弯部24弯折或展开。
所述第一平面部21、所述第一折弯部22、所述第二平面部23、所述第二折弯部24及所述第三平面部25共同承载所述柔性显示屏1。也就是说,所述承载组件2展平时,所述柔性显示屏1贴合所述承载组件2的一面上。所述第一折弯部22及所述第二折弯部24的弯曲变形,使所述第三平面部25折叠至所述第一平面部21与所述第二平面部23之间,且 所述第一平面部21及所述第二平面部23所承载的部分所述柔性显示屏(对应于后文中第一平面显示区11和第二平面显示区13)外露。
在本实施方式中,所述承载组件2展平时,所述第一平面部21、所述第一折弯部22、所述第二平面部23、所述第二折弯部24及所述第三平面部25共面,整个所述柔性显示屏1展平且都可进行显示,因此所述可折叠显示装置100可实现大屏显示,且显示面积较大。所述承载组件2折叠时,所述承载组件2能够通过所述第一折弯部22及所述第二折弯部24的弯曲变形,使所述第三平面部25折叠至所述第一平面部21与所述第二平面部23之间,使得所述承载组件2的长度仅有其在展开时的三分之一左右,所述可折叠显示装置100方便携带,因此所述可折叠显示装置100即可实现大屏显示,并且方便携带。
同时,由于所述承载组件2折叠时,所述第一平面部21及所述第二平面部23所承载的部分所述柔性显示屏(11、13)外露,因此所述柔性显示屏1的大约三分之二的屏幕可进行显示,使得折叠状态下的所述可折叠显示装置100的显示面积仍然较大,从而在折叠状态下也能够满足用户观看体验。所述可折叠显示装置100可在所述第一平面部21所承载的部分所述柔性显示11上显示画面,或者在所述第二平面部23所承载的部分所述柔性显示屏13上显示画面,或者同时在所述第一平面部21和所述第二平面部23所承载的部分所述柔性显示屏(11、13)上显示画面,使得所述可折叠显示装置100的显示方式多样,提高了用户的使用体验。
其中,由于所述第一折弯部22在所述长边方向X的长度大于所述第二折弯部24在所述长边方向X的长度,因此所述第一折弯部22及所述第二折弯部24的弯曲变形时,连接所述第二折弯部24的所述第三平面部25能够折叠至所述第二平面部23与连接所述第一折弯部22的所述第一平面部21之间。
如图3所示,所述承载组件2折叠时,随着所述第一折弯部22和所述第二折弯部24的弯曲变形,不仅所述第一平面部21及所述第二平面部23所承载的部分所述柔性显示屏(11、13)外露,所述第一折弯部22与所述第二折弯部24所承载的部分所述柔性显示屏(对应于后文中第一折弯显示区12和第二折弯显示区14)也外露,从而进一步增加了所述可折叠显示装置100的显示面积,使得所述可折叠显示装置100的显示方式更为多样化。
在其他实施方式中,所述可折叠显示装置100为平板电脑。所述承载组件2处于展平形态时,所述柔性显示屏1整个屏幕大致共面,能够同时进行显示,使得所述可折叠显示装置100可进行大屏显示,用户在观影、游戏时的观看体验极佳。所述承载组件2处于折叠形态时,所述第一平面部21、所述第二平面部23及所述第三平面部25重叠设置,使得所述可折叠显示装置100所占用的平面空间大大缩减,用户可手持所述可折叠显示装置100,或者将所述可折叠显示装置100放入体积较小的收纳包中;并且所述柔性显示屏1的由所述第一平面部21及所述第二平面部23所承载的部分屏幕暴露在外,仍可进行显示(例如显示短信息、天气信息等)。此时,所述柔性显示屏1的由所述第三平面部25所承载的部分隐藏在内侧,不进行显示。
在其他实施方式中,所述可折叠显示装置100为可穿戴设备。例如,所述可折叠显示装置100为手表。所述可折叠显示装置100包括表盘和表带。所述表盘包括所述柔性显示屏1和所述承载组件2。用户佩戴所述可折叠显示装置100或不佩戴所述可折叠显示装置 100时,所述承载组件2均可实现折叠形态和展平形态。所述承载组件2折叠时,所述柔性显示屏1暴露在外的部分的显示面积与所述表盘大致相同,所述柔性显示屏1暴露在外的部分可显示时间、天气、运动数据等信息。并且,用户佩戴所述可折叠显示装置100时,折叠形态的所述承载组件2能够降低用户在活动时撞击、损坏所述可折叠显示装置100的风险;用户不佩戴所述可折叠显示装置100时,折叠形态的所述承载组件2方便用户收纳所述可折叠显示装置100。所述承载组件2展平时,所述柔性显示屏1的整个屏幕进行显示,显示面积远大于所述表盘的面积,从而实现大屏显示。
其中,所述柔性显示屏1可以为有机发光二极管(organic light emitting diode,OLED)显示屏。有机发光二极管是基于有机材料的一种电流型半导体发光器件,由锢锡氧化物半导体薄膜(indium tin oxides,ITO)透明电极层、空穴传输层、有机发光层、电子传输层、金属电极层组成。有机发光二极管的原理是用透明电极层和金属电极层分别作为器件的阳极和阴极,在一定电压驱动下,电子和空穴分别从阴极和阳极注入到电子传输层和空穴传输层,电子和空穴分别经过电子传输层和空穴传输层迁移到有机发光层,并在有机发光层中相遇,形成激子使发光分子激发,经过辆射发出可见光。有机发光二极管用红、蓝、绿像素并置法、色彩转换法(color conversion method,CCM)、白光加彩色滤光片法、微共振腔调色法和多层堆叠法来实现彩色化。有机发光二极管的衬底材料主要有超薄玻璃、金属箔片和聚合物。其中,当玻璃厚度下降到50μm(微米)至200μm(微米)时能够弯曲,可进行折叠。
其中,所述柔性显示屏1可以为触控式显示屏,以实现显示功能与触控功能。也即,所述柔性显示屏1能够在显示图像时,感测用户的触摸动作,以与用户进行交互。例如,可在有机发光二极管显示屏中嵌入触控层,以使有机发光二极管显示屏具有触控功能。或者,设置一触控屏,并使所述触控屏与所述有机发光二极管显示屏层叠设置,以使两者组合成的显示模组兼具显示和触控功能。

请一并参阅图1至图3,第一种实施方式中,所述第一壳体3固定于所述第二平面部23的背离所述柔性显示屏1的一侧。所述承载组件2折叠时,所述第一壳体3位于所述第三平面部25与所述第二平面部23之间。在所述承载组件2自展平状态向折叠状态变化的过程中,所述第二折弯部24先弯折,以使第三平面部25移动至所述第一壳体3远离所述第二平面部23的一侧;然后弯折所述第一折弯部22,以使所述第一平面部21位于所述第三平面部25远离所述第一壳体3的一侧。
在本实施方式中,由于可折叠显示装置100的多个器件均设置在第一壳体3中,且所述第一壳体3固定于所述第二平面部23的背离所述柔性显示屏1的一侧,因此所述承载组 件2折叠时,所述第一壳体3位于所述第三平面部25与所述第二平面部23之间,所述可折叠显示装置100无需在第一平面部21与第三平面部25之间预留厚度给其他器件排布,所述第一平面部21与所述第三平面部25可紧凑排布,从而降低所述可折叠显示装置100在折叠时的整体厚度,提高所述可折叠显示装置100的便携性。

在本实施方式中,由于可折叠显示装置100的多个器件均设置在第一壳体3中,且所述第一壳体3固定于所述第一平面部21的背离所述柔性显示屏1的一侧,因此所述承载组件2折叠时,所述第一壳体3位于所述第三平面部25与所述第一平面部21之间,所述可折叠显示装置100无需在第二平面部23与第三平面部25之间预留厚度给其他器件排布,所述第二平面部23与所述第三平面部25可紧凑排布,从而降低所述可折叠显示装置100在折叠时的整体厚度,提高所述可折叠显示装置100的便携性。

在本实施方式中,由于可折叠显示装置100的多个器件均设置在第一壳体3中,且所述第一壳体3固定于所述第三平面部25的背离所述柔性显示屏1的一侧,因此所述承载组件2折叠时,所述第一壳体3位于所述第三平面部25与所述第一平面部21之间,所述可折叠显示装置100无需在第二平面部23与第三平面部25之间预留厚度给其他器件排布,所述第二平面部23与所述第三平面部25可紧凑排布,从而降低所述可折叠显示装置100在折叠时的整体厚度,提高所述可折叠显示装置100的便携性。

其中,所述可折叠显示装置100的多个器件可依据需求排布在所述第一壳体41和所述第二壳体42中。例如,所述第一壳体41的厚度小于所述第二壳体42的厚度。厚度较小的器件可放置在所述第一壳体41中,厚度较大的器件可放置在所述第二壳体42中,从而提 高对所述第一壳体41和所述第二壳体42的空间利用率,进而降低所述可折叠显示装置100在折叠状态中的整机厚度。在其他实施方式中,第一壳体41的厚度也可大于第二壳体42的厚度。
