在一种具体实施例中,至少部分第一表面设有沿预设方向排布的多个第一形状部,转轴的外周设有至少一个第二形状部,对于分别设置于第一表面21和转轴3上配合的第一形状部22和第二形状部31,多个第一形状部22可以是沿预设方向排布的多个齿条,相邻的齿条间形成凹陷,多个第二形状部31可以是在转轴3的外侧壁上绕周向布置的多个齿轮,多个齿轮与转轴3一体成形以形成齿轮轴,至少部分的齿轮能够部分伸入齿条间的凹陷位置,以使齿轮与齿条能够啮合,显示面板1通过齿轮轴分为处于第一状态S1的部分与处于第二状态S2的部分,齿轮轴能够带动支撑层2转动,使得部分显示面板1在第一状态S1与第二状态S2之间转换。第一形状部22和第二形状部31也可以设置为如配合的凸起与凹陷等形式来实现转轴3带动支撑层2的转动,在此不做具体限定。
本申请实施例提供的显示模组,在控制显示面板1中处于第一状态S1部分的面积增大或减小的过程中,由于支撑层2的设置,能够为绕设于转轴3的显示面板1提供支撑力,避免显示面板1在反复的使用中容易褶皱变形。并且,通过在支撑层2上设置配合的第一形状部22和第二形状部31,以便于显示面板1实现滑移,同时第一形状部22和第二形状部31配合的位置处于支撑层2和转轴3之间,避免转轴3转动过程中所产生的力直接作用于显示面板1的对应绕设于转轴3的部分,进而降低了显示面板1对应转轴3位置的应力集中,避免显示面板1受到损害,提高了显示面板1的使用性能,不易受损。
支撑层2及显示面板1绕设于转轴3的配合中,转轴3可以设置为一个,也可以设置为多个。
参阅图1和图2,当转轴3仅设置为一个时,支撑层2在第一方向L的一侧绕设于转轴3的外周,多个第一形状部22在第一表面21排布的预设方向为第一方向L,绕设于转轴3的支撑层2及显示面板1通过转轴3被划分为处于第一状态S1的部分和处于第二状态S2的部分,处于第二状态S2的部分位于处于第一状态S1的部分的正下方,转轴3能够沿自身的轴线正向或反向转动,而使转轴3上的不同的第二形状部31能够与不同的第一形状部22实现配合,而使转轴3在转动过程中,使显示面板1中处于第一状态S1的部分面积增大、处于第二状态S2的部分面积随之减少,或者,使显示面板1真难过处于第一状态S1的部分面积减少、处于第二状态S2的部分面积随之增大。
参阅图4和图5,当转轴3设置为两个,且支撑层2在第一方向L的两侧分别绕设相应的两个转轴3时,即第一转轴和第二转轴,多个第一形状部22在第一表面21排布的预设方向为第一方向L,绕设于第一转轴和第二转轴的支撑层2及显示面板1通过第一转轴和第二转轴被划分为处于第一部状态S1的部分和处于第二状态S2的部分,处于第二状态S2的部分位于处于第一状态S1的部分的正下方,第一转轴和第二转轴分别能够沿自身轴线正向或反向转动,且第一转轴和第二转轴的转动方向相反,第一转轴和第二转轴在相反方向的转动过程中,通过第一形状部22和第二形状部31的配合可以使显示面板1中处于第一状态S1的部分的面积增大、处于第二状态S2的部分的面积减少,或者,使显示面板1中处于的第一状态S1的部分的面积减少、处于第二状态S2的部分的面积增大。
可选的,当转轴3设置为两个以上时,能够有支撑层2在第一方向L的至少一侧绕设有转轴3时,也可以有支撑层2在第二方向W的至少一侧绕设有转轴3,不仅在第一方向L排布有多个第一形状部22,而且在第二方向W同样设有多个第一形状部22,第一方向L与第二方向W交叉,从而可以根据需求调节不同方向、不同位置的转轴3,以通过相应位置的第一形状部22和第二形状部31的配合,而使转轴3转动时,带动显示面板1中处于第一状态S1的部分的面积的增大或减小。
多个第一形状部22在第一表面21沿预设方向的排布,是根据所设置 的第二形状部31的数量、排布方式、所需调节的位置所决定的。
参阅图6,支撑层2的第一表面21包括配合区D1和贴合区D2,贴合区D2位于配合区D1沿垂直于转轴3的轴向方向上的至少一侧,第一形状部22设置于配合区D1,贴合区D2表面平整。通过贴合区D2表面平整的设置,用于将支撑层2贴合固定于对应位置,以实现显示面板1的安装固定,避免显示面板1容易脱落。在此需要强调的是,对于第一表面21所划分的配合区D1和贴合区D2,根据所设置的转轴3与支撑层2的配合结构的不同可以适应性调整,并不限于贴合区D2位于配合区D1沿垂直于转轴3的轴向方向上的至少一侧的布置形式。只要能够使第一表面21具有平整的贴合区D2以将显示面板1固定连接,以提高连接的强度、稳定性,且第一表面21具有的配合区D1能够根据相应位置的转轴3而设置对应的多个沿预设方向排布的第一形状部22,以调节显示面板1中处于第一状态S1的部分的面积而不会造成应力集中影响显示面板1的使用性能即可。
在一些可选的实施例中,设置于显示面板1的非显示面11的支撑层2,为具有变形能力且具有一定强度的结构,例如钢板。从而能够对柔性的显示面板1提供支撑力,以避免在调节显示面板1中处于第一状态S1的部分的面积大小时容易造成显示面板1局部产生褶皱,同时,在支撑层2设置与多个第二形状部31啮合的多个第一形状部22,转轴3转动的力作用于支撑层2上,避免了对显示面板1的直接损伤。
可选的,由于支撑层2需要部分绕设于转轴3,为了保证支撑层2具有较好的变形能力,参阅图7,支撑层2设有均匀分布的多个第一通孔23,以平衡受力。而在支撑层2上设置多个第一通孔23以提高支撑层2的变形能力时,多个第一通孔23至少均匀布置于配合区D1,在此基础上,可以在配合区D1布置多个第一形状部22。在将第一形状部22连接于具有多个第一通孔23的配合区D1时,会存在第一形状部22在显示面板1的正投影方向与第一通孔23至少部分重叠的情况,即所述第一形状部在所述配合区上的正投影至少部分位于所述第一通孔内,或者,也可以将第一形状部22与支撑层2一体成形,第一通孔23均匀布置于配合区D1时,第一通孔23进一步贯通部分的第一形状部22,在此不做具体限定。
参阅图8和图9,当第一形状部22和第二形状部31为啮合的齿轮和齿条时,多个齿条在配合区D1沿贴合区D2和配合区D1的布置方向排布,且多个齿条的截面呈波浪形。以节约齿轮轴转动时不同齿轮与齿条啮合转换的力,有利于啮合运动的效果。
可选的,齿条与支撑层2可以一体成形,以提高连接的强度。
而为了避免所设置的第一通孔23影响齿条与支撑层2的配合、齿条与齿轮轴的啮合、以及贴合区D2贴合固定的强度,多个第一通孔23均匀设置于配合区D1,且第一通孔23所设置的位置不与齿条干涉,例如,第一通孔23可以位于相邻齿条之间所形成的凹陷位置,或者,第一通孔23也可以位于配合区D1中未设置多个齿条的位置。
在一种具体实施例中,多个第一形状部22也可以直接设置为在配合区D1配置的多个第二通孔,例如多个第二通孔阵列排布于配合区D1,多个第二形状部31设置为在转轴3周向布置的多个凸起,为了实现与阵列排布的第二通孔实现配合,多个凸起在转轴3周向上的外表面呈点阵排布,以使转轴3在转动的过程中能够带动不同的凸起与对应的第二通孔配合,进而通过两者的配合实现带动支撑层2及显示面板1的运动,同时,通过第二通孔在支撑层2的设置,提高了支撑层2自身的变形能力的同时能够有足够的支撑力对显示面板1进行支撑,提高显示面板1使用的稳定性。
以下以转轴3仅设置为一个时,支撑层2在第一方向L的一侧绕设于转轴3的结构配合为例,对显示模组的结构做具体说明:
参阅图10和图11,显示模组还包括第一框架5和第二框架6,第二框架6与第一框架5相对设置,第二框架6与第一框架5至少围合有第一窗口D4,第一框架5和第二框架6中的内部用于放置电子部件,第二框架6与第一框架5能够彼此靠近或远离,以改变第一窗口D4的面积,显示面板1中处于第一状态S1的部分设置于第一窗口D4,以使处于第一状态S1的部分为可视部分,处于第二状态S2的部分通过绕设于齿轮轴后使其始终位于第一框架5和第二框架6的内部,以使处于第二状态S2的部分为不能够被看到的收纳部分。
可选的,第一框架6和第二框架5中对应显示面板1中处于第二状态 S2的部分位置还可以设置有第二窗口D5,显示面板1中处于第二状态S2的至少部分能够通过第二窗口D5实现部分可视,以能够根据需求在不同方向均有显示面板1的部分能够可视,提高使用性能。
需要说明的是,第二框架6与第一框架5能够彼此靠近或远离的方式可以有多种选择,例如在一些实施例中可以将第二框架6和第一框架5中分别设置配合的导轨和滑块,而使在外力作用下驱动第二框架6时,能够使第二框架6沿第一方向L运动以靠近或远离第一框架5,进而调节两者围合而成的第一窗口D4面积的大小。
在将显示面板1、支撑层2、转轴3安装于第一框架5和第二框架6中时,第一框架5包括平行于转轴3延伸的第一边框51,第二框架6包括平行于转轴3延伸的第二边框61,第一边框51、第二边框61中的至少一者处设有转轴3。
在一些可选的实施例中,第二框架6能够相对第一框架5沿第一方向L靠近或远离,贴合区D2位于支撑层2在第一方向L的一侧,用于与第一框架5贴合固定,另一侧绕设于转轴3,支撑层2中的贴合区D2与第一框架5固定连接,转轴3位于对应第二边框61的位置,转轴3转动连接于第二框架6中,通过操作第二框架6产生相对第一框架5靠近或远离的运动,转轴3能够随着第二框架6产生在第一方向L同样的靠近或远离第一框架5的运动。并且在此种转轴3随着沿第一方向L滑移的运动过程中,转轴3能够转动,以通过转动的力而使其上的第二形状部31作用于支撑层2中配合的第一形状部22,实现不同第一形状部22和第二形状部31的啮合,进而在实现第一窗口D4面积改变的同时显示面板1中处于第一状态S1的部分的面积也能够随之改变,避免显示面板1局部出现褶皱。
可选的,参阅图9,支撑层2还包括位于第一表面21的导向区D3,导向区D3具有导向平面,配合区D1在第一方向L的两侧分别为导向区D3和贴合区D2,在支撑层2及显示面板1绕设转轴3时,导向区D3和贴合区D2位于转轴3的两侧,两者相互平行。在第二框架6中设有限位部,具有限位平面,支撑层2的导向区D3至少部分伸入限位部,而使导向区D3的导向平面与限位平面至少部分接触配合,且在转轴3转动时导向平面能 够沿限位平面产生相对的运动,而使位于转轴3两侧的显示面板1部分处于相互平行的状态,提高转轴3转动时与第一形状部22和第二形状部31配合的效果,避免显示面板1局部产生褶皱。
在另外一些可选的实施例中,显示模组还包括距离检测装置7,设置于第一框架5和第二框架6的至少一者上,用于获得第一框架5与第二框架6之间的距离信息;驱动装置4,与转轴3连接,用于驱动转轴3转动;以及控制器,与距离检测装置7、驱动装置4电连接,控制器根据距离信息控制驱动装置4转动。通过所设置的距离检测装置7以检测第二框架6相对第一框架5是否产生滑移,并将检测信息反馈至控制器,以便于控制器能够根据反馈的信息控制驱动装置4工作与否,进而实现控制转轴3的转动或停止转动,以实现显示面板中处于第一状态S1的部分的面积增大或减小的自动调节。
可选的,距离检测装置7包括第一检测部71和第二检测部72,第一检测部71设置于第一框架5,第二检测部72设置于第二框架6,第一检测部71和第二检测部72在垂直于转轴3的轴向方向上相对设置。
可选的,驱动装置4可以为电机,电机的输出轴同轴固定连接于转轴3的一侧,通过电机的启动能够带动转轴3绕自身轴线转动。
显示模组包括运动状态、暂停状态和张紧状态,在运动状态,第二框架6与第一框架5彼此靠近或远离,转轴3带动支撑层2转动,使得部分显示面板1在第一状态S1和第二状态S2之间转换;在暂停状态,第二框架6与第一框架5之间的距离不变,转轴3暂停转动;在运动状态转换至暂停状态转换时,第二框架6与第一框架5之间维持在暂停状态的距离,转轴3带动支撑层2转动预设角度,以张紧显示面板1中处于第一状态S1的部分,使得显示模组处于张紧状态。
可以理解为,将第二框架6位于与第一框架5距离最近(参阅图11)、第一框架5和第二框架6所围合成的第一窗口D4的面积最小时的状态定义为初始状态,在此初始状态下,当存在外力使第二框架6产生沿第一方向L远离第一框架5的运动时,距离检测装置7检测到第一框架5和第二框架6之间距离增大,并形成第一检测信号,将该第一检测信号反馈 至控制器,控制器在接收到第一检测信号后,控制驱动装置4启动,带动转轴3转动,转轴3在随着第二框架6同时向远离第一框架5的方向运动的同时,转轴3的转动使其不同的第二形状部31与支撑层2上不同的第一形状部22产生配合的相对运动,从而带动位于支撑层2上的显示面板1的局部产生滑移,进而使显示面板中处于第一状态S1的可视部分面积增大,处于第二状态S2的不可视部分的面积减小。至第一状态S1的可视部分的面积增大至所需的面积后,撤销外力,第二框架6相对第一框架5之间的距离停止改变,两者处于暂停状态,此时距离检测装置7检测到第一框架5和第二框架6之间的距离停止改变,形成第二检测信号,将该第二检测信号反馈至控制器,控制器在接收到第二检测信号后,先使显示模组处于张紧状态,即控制驱动装置4继续启动,并使转轴3在此时带动支撑层2转动预设角度,以实现对显示面板1中处于第一状态S1的部分提供展平力,使显示面板1平整,使得屏幕表面处于张紧状态,没有小的皱褶。再使显示模组进入并维持在暂停状态,即通过张紧状态展平显示面板1后,控制器控制驱动装置4停止运动,对转轴3的作用力消失后,第一形状部22和第二形状部31维持该配合状态并相对静止,显示面板中处于第一状态S1的部分的面积维持在此时的大小(参阅图10)。同理,当存在外力使第二框架6产生沿第一方向L靠近第一框架5的运动时,与上述的原理相同,在此不再赘述。
可选的,在进入张紧状态时,使转轴3带动支撑层2所转动的预设角度,可以为1度到3度,其目的在于能够向显示面板1提供展平力,所设置的预设角度的大小,与实际显示面板1自身的柔性等因素有关,在此不做具体限定。
本申请实施例还提供了一种显示装置,该显示装置可以为手机、平板电脑或其他具有显示功能的电子设备,该显示装置包括显示模组,该显示模组为上述中任一实施例所述的显示模组,以通过所设置的显示模组实现所需的屏幕展平部分面积的增大或减小。
