Description

支撑板及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种支撑板及显示装置。
 背景技术
随着有机发光二极管（Organic Light-Emitting Diode，OLED）技术的发展，消费者对高屏占比的需求不断提升。因此，为最大限度提高OLED显示屏的占比，显示领域业内的研究重点已从传统二维平面式屏幕向三维曲面式OLED转移。然而，受当前模组制程能力的限制，高屏占比的曲面式OLED屏的良率一直无法达到设计要求。主要是在模组在立体贴合成型过程中，模组材料之间界面因受力不均容易导致器件层和材料层间脱粘，极大地影响着良率的提升。此外，因屏下指纹的开发需求，模组叠构中常设计有对应指纹传感的开孔。开孔的存在，破坏了原有模组支撑层的整面平整性，在贴合时因治具设备的顶压力的存在，会在开孔周围形成印痕。印痕的存在，会在屏体的表面形成显示不良，如残影、色相不均、暗线、黑斑的现象。因此，有效解决OLED曲面屏在立体贴合过程中，提高曲边贴合良率，以及降低开孔周围存在印痕现象是当前亟需解决的制程问题。

可选的，在本实施例中，第一区Q1围绕在镂空孔lk的周侧。第二区Q2也围绕在第一区Q1的周侧。这样的设置使得，在进行模组压合时，同时降低镂空孔lk四周的压痕。
在一些实施例中，第一区Q1也可以是仅设置在镂空孔lk的一侧；第二区Q2包围第一区Q1和镂空孔lk。
在一些实施例中，第一区Q1也可以是设置在镂空孔lk的两侧；第二区Q2包围第一区Q1和镂空孔lk。
在一些实施例中，第一区Q1也可以包围镂空孔lk的部分，比如包围镂空孔lk的孔壁周长的四分之三；第二区Q2包围第一区Q的部分，比如包围镂空孔lk的孔壁周长的四分之三。
可选的，本实施例中，支撑板100包括平坦部分11和连接于平坦部分11至少一侧的弯曲部分12。第一区Q1、第二区Q2和镂空孔lk设置在平坦部分11上。
需要说明的是，本申请的支撑板100也可以是平板或曲面板。本实施例以支撑板100包括平坦部分11和弯曲部分12为例进行说明，但并不限于此。
可选的，开口kk包括两条第一边线和两条相对设置的第二边线，一第一边线连接于两条第二边线的一侧，第一边线呈圆弧状。
其中第一边线采用圆弧状的设计可以更好地释放应力，以及降低开口kk的口壁应力集中的问题。
可选的，位于直边区QA的开口kk，也就是第一开口k1。第一开口k1的第二边为直边。位于弯曲区QB的开口kk，也就是第二开口k2。第二开口k2的第二边为圆弧边。可选的，第一区Q1包括至少一个直边区QA。其中直边区QA有四个，四个直边区QA两两相对设置，且围绕在镂空孔lk的四周。
请参照图3，直边区QA包括多个直边子区Q11。自镂空孔lk的边缘向远离镂空孔lk的方向上，多个直边子区Q11依次排列设置，且相邻两个直边子区Q11的刚度递增。
本实施例在第一区Q1的直边区QA采用渐变式的方式，即保证了支撑板100对应于第一区Q1的部分的支撑性，又达到释放应力的效果；也即在保证第一区Q1支撑性的基础上，达到改善压痕的效果。
当然，在一些实施例中，直边区QA对应的刚性也可以采用非渐变式，比如任意两个直边子区Q11对应的刚性相等或不等。
可选的，多个开口kk包括设置在直边子区Q11的第一开口k1。第一开口k1的长度方向为直边子区Q11的延伸方向。自镂空孔lk的边缘向远离镂空孔lk的方向上，在任意两个直边子区Q11中，靠近镂空孔lk的直边子区Q11的第一开口k1的长度大于远离镂空孔lk的直边子区Q11的第一开口k1的长度。
可以理解的是，第一开口k1的长度越大，则其对应的直边子区Q11的拉伸模量越小，进而刚度越小。因此通过第一开口k1的长度的渐变，来实现直边区QA中刚度的渐变。
可选的，直边子区Q11包括至少一排第一开口k1。本实施例以直边子区Q11包括一排第一开口k1为例进行说明，但不限于此。
可选的，第一开口k1的长度的渐变可以按照设定规则进行缩小，设定规则可是相同或不同的第一设定比例或第一设定数值等。比如自镂空孔lk的边缘向远离镂空孔lk的方向上，依次排布有第一直边子区Q11a、第二直边子区Q11b和第三直边子区Q11c。第一直边子区Q11a中的第一开口k1的长度La等于第二直边子区Q11b中的第一开口k1的长度Lb与第一设定值之和；第二直边子区Q11b中的第一开口k1的长度Lb等于第三直边子区Q11c中的第一开口k1的长度Lc与第一设定值之和。
亦或者，第二直边子区Q11b中的第一开口k1的长度Lb等于第一直边子区Q11a中的第一开口k1的长度La的四分之三；第三直边子区Q11c中的第一开口k1的长度Lc等于第二直边子区Q11b中的第一开口k1的长度Lb的四分之三。
第一设定比例和第一设定值，可根据实际情况进行设定和调整，此处不再赘述。
可选的，自镂空孔lk的边缘向远离镂空孔lk的方向上，在任意两个直边子区Q11中，靠近镂空孔lk的直边子区Q11的第一开口k1之间的第一间距小于远离镂空孔lk的直边子区Q11的第一开口k1之间的第一间距。
可以理解的是，第一间距的距离越大，则其对应的直边子区Q11的拉伸模量越大，进而刚度越大。因此通过第一间距的宽度的渐变，来实现直边区QA中刚度的渐变。
可选的，第一间距的宽度的渐变可以按照设定规则进行放大，设定规则可是相同或不同的第二设定比例或第二设定数值等。比如第一直边子区Q11a中第一间距的宽度L1与第二设定值之和等于第二直边子区Q11b中第一间距的宽度L2；第二直边子区Q11b中第一间距的宽度L2与第二设定值之和等于第三直边子区Q11c中第一间距的宽度L3。
亦或者，第二直边子区Q11b中第一间距的宽度L2的四分之三等于第一直边子区Q11a中第一间距的宽度L1；第三直边子区Q11c中第一间距的宽度L3的四分之三等于第二直边子区Q11b中第一间距的宽度L2。
第二设定比例和第二设定值，可根据实际情况进行设定和调整，此处不再赘述。
本实施例采用第一开口k1的长度与第一间距的距离同时进行渐变，提高渐变的效果，也即使得在有限的区域中快速的实现刚度的渐变，缩短直边区QA的空间。
可选的，平行于镂空孔lk的周沿方向上，每一直边子区Q11的第一开口k1间隔排列设置，相邻两个第一开口k1之间具有所述第一间距。
其中，在任意两个直边子区Q11中，第一开口k1的长度与第一间距之和相等。
也即，某一直边子区Q11中的第一开口k1的长度与第一间距之和等于另一直边子区Q11的第一开口k1的长度与第一间距之和。
比如，长度La+宽度L1=长度Lb+宽度L2=长度Lc+宽度L3。
本实施例采用第一开口k1的长度值和第一间距的宽度值之和保持一致，使得直边子区Q11的刚度进行规律性的缩小，提高了应力释放效果和支撑性的平滑过渡，且可提高制备效率。
另外，本实施例中，自镂空孔lk的边缘向远离镂空孔lk的方向上，某一排的一第一开口k1与其相邻排的两个第一开口k1部分重叠设置。
也即相邻排的第一开口k1错开且部分重叠设置，这样的设置提高了第一区Q1中应力释放效果的均一性。
可选的，奇数排的第一开口k1沿着镂空孔lk的边缘向远离镂空孔lk的方向排列成行，每行第一开口k1的中心线重合。至少一偶数排位于所述中心线两侧的两个第一开口k1的图案关于所述中心线对称设置。
这样的设置可进一步提供第一区Q1刚性的均匀性。
可选的，在一些实施例中，直边子区Q11也可以包括多排第一开口k1。多排第一开口k1沿着镂空孔lk的边缘向远离镂空孔lk的方向排列。在一直边子区Q11中，相邻的两列第一开口k1错开设置。在同一直边子区Q11中，第一开口k1的长度均相等；相邻的两个第一开口k1之间的间距也相等。
当然在一些实施例中，在同一直边子区Q11中，第一开口k1的长度也可以不相等或部分相等；相邻的两个第一开口k1之间的间距也可以是不相等或部分相等。
可选的，请参照图2，第一区Q1包括至少一个弯曲区QB。
在本实施例中，四个弯曲区QB设置在镂空孔lk的四角区域，一弯曲区QB连接在两个直边区QA之间。弯曲区QB和直边区QA依次相连围设在镂空孔lk的周侧。
可选的，请参照图4，弯曲区QB包括多个弯曲子区Q12；第一区Q1还可以包括多个弯曲子区Q12。在第一区Q1中，自镂空孔lk的边缘向远离镂空孔lk的方向上，多个弯曲子区Q12依次排列设置，相邻两个弯曲子区Q12的刚度递增。
本实施例在第一区Q1的弯曲区QB采用渐变式的方式，即保证了支撑板100对应于第一区Q1的部分的支撑性，又达到释放应力的效果；也即在保证第一区Q1支撑性的基础上，达到改善压痕的效果。
当然，在一些实施例中，第一区Q1的弯曲区QB对应的刚性也可以采用非渐变式，比如任意两个的弯曲子区Q12对应的刚性相等或不等。
可选的，多个开口kk包括设置在弯曲子区Q12的第二开口k2。第二开口k2的弧长度方向为弯曲子区Q12的延伸方向。自镂空孔lk的边缘向远离镂空孔lk的方向上，在任意两个弯曲子区Q12中，靠近镂空孔lk的弯曲子区Q12的第二开口k2的弧长度大于远离镂空孔lk的弯曲子区Q12的第二开口k2的弧长度。
可以理解的是，第二开口k2的弧长度越大，则其对应的弯曲子区Q12的拉伸模量越小，进而刚度越小。因此通过第二开口k2的弧长度的渐变，来实现第一区Q1中刚度的渐变。
可选的，弯曲子区Q12包括至少一排第二开口k2。本实施例以弯曲子区Q12包括一排第二开口k2为例进行说明，但不限于此。
可选的，第二开口k2的弧长度的渐变可以按照设定规则进行缩小，设定规则可是相同或不同的第三设定比例或第三设定数值等。比如自镂空孔lk的边缘向远离镂空孔lk的方向上，依次排布有第一弯曲子区Q12a、第二弯曲子区Q12b和第三弯曲子区Q12c。第一弯曲子区Q12a中的第二开口k2的弧长度Ha等于第二弯曲子区Q12b中的第二开口k2的弧长度Hb与第三设定值之和；第二弯曲子区Q12b中的第二开口k2的弧长度Hb等于第三弯曲子区Q12c中的第二开口k2的弧长度Hc与第三设定值之和。
亦或者，第二弯曲子区Q12b中第二开口k2的弧长度Lb等于第一弯曲子区Q12a中第二开口k2的弧长度Ha的四分之三；第三弯曲子区Q12c中的第二开口k2的弧长度Hc等于第二弯曲子区Q12b中的第二开口k2的弧长度Hb的四分之三。
第三设定比例和第三设定值，可根据实际情况进行设定和调整；比如第三设定值可以是5度、10度或15度的弧长度。
可选的，任意两个第二开口k2同圆点设置。
请参照图5，可选的，多个开口kk还包括补偿开口kc，补偿开口kc设置在第一开口k1和第二开口k2之间，补偿开口kc设置在弯曲区QB内。
补偿开口kc的弧度半径与其同一弯曲子区Q12的第二开口k2的弧度半径相等。
在平行于镂空孔lk边缘的方向上，补偿开口kc到第一开口k1的距离大于补偿开口ck到第二开口k2的距离。这样的设置以提高弯曲区QB应力释放的均匀性。
可以理解的是，第一区Q1包括至少一直边区QA。直边区QA包括多个直边子区Q11。多个开口kk包括设置在直边子区Q11的第一开口k1。
自镂空孔lk的边缘向远离镂空孔lk的方向上，多个直边子区Q11依次排列设置，直边子区Q11对应连接一弯曲子区Q12。
多个开口kk包括第三开口k3。第三开口k3包括相连的第一部分k31和第二部分k32。第一部分k31设置在直边区QA，第二部分k32设置在弯曲区QB。
平行于镂空孔lk的周沿方向上，第一部分k31的延伸方向与第一开口k1的延伸方向一致，第二部分k32的弧度方向平行于第二开口k2的弧度方向。
第三开口k3设置在第一开口k1和第二开口k2之间，起到缓冲直边子区Q11和弯曲子区Q12的效果，提高了第一区Q1释放应力的均匀性。
可选的，多个弯曲子区Q12同圆心设置，且多个弯曲子区Q12的圆心角为90度。一直边子区Q11的中线z1和与该直边子区Q11相连的弯曲子区Q12的中线z2相切。
具体的，请参照图5，多个弯曲子区Q12的中线z2也是同圆心设置。在同一直边子区Q11中，中线z1与第一开口k1的中线重合。在同一弯曲子区Q12中，中线z2与第二开口k2的中线重合。
在一直边子区Q11和与其连接的弯曲子区Q12中，中线z1正好与弯曲子区Q12的中线z2相切；同时，第一开口k1的中线也与第二开口k2的中线相切。
可选的，结合图1，本实施例中，支撑板100包括平坦部分11和连接于平坦部分11至少一侧的弯曲部分12。第一区Q1、第二区Q2和镂空孔lk设置在平坦部分11上。
支撑板100上还设置有对应于弯曲部分12的第三区Q3。多个开口kk还包括第四开口k4，多个第四开口k4设置在第三区Q3上。
支撑板100对应于第三区Q3的弯曲部分12的刚度小于支撑板100对应于第二区Q2的平坦部分11的刚度。
需要说明的是，当支撑板100用于支撑两侧为曲面的显示面板时，由于面板两侧为曲面，而显示面板因弯曲所带来的应力越大，因此需要支撑板100的弯曲部分12具有相应的应力释放能力。也因此，上述的设置，提高了第三区Q3的应力释放效果，便于支撑板100和面板的贴合，同时也降低压痕出现的风险。
可选的，请参照图6，第三区Q3包括多个竖直子区Q31。在第三区Q3中，自靠近第二区Q2一侧向远离第二区Q2一侧的方向上，多个竖直子区Q31依次排列设置，且相邻两个竖直子区Q31的刚度递减。
当支撑板100用于支撑两侧为曲面的面板时，由于面板两侧为曲面，越靠近曲面边缘的弯曲度越大，进而面板因弯曲所带来的应力越大，因此本实施采用刚度递减的渐变方式，使得支撑板100的受力更为均衡，不但便于支撑板100与面板的贴合，而且提高了支撑板100的使用寿命。
当然，在一些实施例中，第三区Q3对应的刚性也可以采用非渐变式，比如任意两个直边子区Q11对应的刚性相等或不等。
可选的，第四开口k4的长度方向为第三区Q3的延伸方向。在第三区Q3中，自靠近第二区Q2一侧向远离第二区Q2一侧的方向上，第四开口k4的长度递增。
可以理解的是，第四开口k4的长度越大，则其对应的竖直子区Q31的拉伸模量越小，进而刚度越小。因此通过第四开口k4的长度的渐变，来实现第三区Q3中刚度的渐变。
可选的，竖直子区Q31包括至少一排第四开口k4。本实施例以竖直子区Q31包括一排第四开口k4为例进行说明，但不限于此。
可选的，第四开口k4的长度的渐变可以按照设定规则进行放大，设定规则可是相同或不同的第四设定比例或第四设定数值等。比如自靠近第二区Q2一侧向远离第二区Q2一侧的方向上，依次排布有第一竖直子区Q31a、第二竖直子区Q31b和第三竖直子区Q31c。第一竖直子区Q31a中第四开口k4的长度Da与第四设定值之和等于第二竖直子区Q31b中第四开口k4的长度Db；第二竖直子区Q31b中第四开口k4的长度Db与第四设定值之和等于第三竖直子区Q31c中第四开口k4的长度Dc。
亦或者，第二竖直子区Q31b中的第四开口k4的长度Db的五分之四等于第一竖直子区Q31a中第四开口k4的长度Da；第三竖直子区Q31c中第四开口k4的长度Dc的五分之四等于第二竖直子区Q31b中第四开口k4的长度Db。
第四设定比例和第四设定值，可根据实际情况进行设定和调整，此处不再赘述。
可选的，自靠近第二区Q2一侧向远离第二区Q2一侧的方向上，在任意两个竖直子区Q31中，靠近第二区Q2的竖直子区Q31的第四开口k4之间的第二间距大于远离第二区Q2的竖直子区Q31的第四开口k4之间的第二间距。
可以理解的是，第二间距的距离越大，则其对应的竖直子区Q31的拉伸模量越大，进而刚度越大。因此通过第二间距的宽度的渐变，来实现第三区Q3中刚度的渐变。
可选的，第二间距的宽度的渐变可以按照设定规则进行缩小，设定规则可是相同或不同的第五设定比例或第五设定数值等。比如第一竖直子区Q31a中第二间距的宽度L4等于第二竖直子区Q31b中第二间距的宽度L5与第五设定值之和；第二竖直子区Q31b中第二间距的宽度L5等于第三竖直子区Q31c中第二间距的宽度L6与第五设定值之和。
亦或者，第二竖直子区Q31b中第二间距的宽度L5的四分之三等于第一竖直子区Q31a中第二间距的宽度L4；第三竖直子区Q31c中第二间距的宽度L6的四分之三等于第二竖直子区Q31b中第二间距的宽度L5。
第五设定比例和第五设定值，可根据实际情况进行设定和调整，此处不再赘述。
本实施例采用第四开口k4的长度与第二间距的距离同时进行渐变，提高渐变的效果，也即使得在有限的区域中快速的实现刚度的渐变，缩短第三区Q3的空间。
可选的，多个竖直子区Q31沿着第一方向x排列。在每一竖直子区Q31中，第四开口k4沿着第二方向y间隔排列。第一方向x为弯曲部分12的弯曲方向。第二方向y垂直于第一方向x。
在第二方向y上，同一竖直子区Q31的相邻两个第四开口k4之间具有所述第二间距。
其中，在任意两个竖直子区Q31中，第四开口k4的长度与所述第二间距之和相等。
也即，某一竖直子区Q31中第四开口k4的长度与第二间距之和等于另一竖直子区Q31的第四开口k4的长度与第二间距之和。
比如，长度Da+宽度L4=长度Db+宽度L5=长度Dc+宽度L6。
本实施例采用第四开口k4的长度值和第二间距的宽度值之和保持一致，使得竖直子区Q31的刚度进行规律性的缩小，提高了应力释放效果和支撑性的平滑过渡，且可提高制备效率。
可选的，竖直子区Q31包括至少一排第四开口k4。在第一方向x上，某一排的一第四开口k4与其相邻排的两个第四开口k4部分重叠设置。
也即相邻排的第四开口k4错开且部分重叠设置，这样的设置提高了第三区Q3中应力释放效果的均一性。
可选的，在一些实施例中，竖直子区Q31包括多排第四开口k4。多排第四开口k4沿着第一方向x排列。在一竖直子区Q31中，相邻的两列第四开口k4错开设置。在同一竖直子区Q31中，第四开口k4的长度均相等；相邻的两个第四开口k4之间的间距也相等。
当然在一些实施例中，在同一竖直子区Q31中，第四开口k4的长度也可以不相等或部分相等；相邻的两个第四开口k4之间的间距也可以是不相等或部分相等。
相应的，请参照图7，本申请实施例还提供一种显示装置1000，其包括如上述任一实施例的支撑板100、缓冲层200、胶体300和显示面板400。
缓冲层200设置在支撑板100上。缓冲层200上设置有对应于镂空孔lk的开孔mk。镂空孔lk的孔壁位于开孔mk的孔壁的外周侧。
胶体300设置在缓冲层200上。显示面板400设置在胶体300上。
需要说明的是，本实施例的显示装置1000的支撑板100的结构与上述任意实施例的支撑板100的结构相似或相同，具体请参照上述实施例的支撑板100所阐述的内容，此处不再赘述。
本申请实施例显示装置1000中，支撑板100上设置有一用于设置模组的镂空孔lk和多个开口kk；支撑板100设置有第一区Q1和第二区Q2，多个开口kk设置在第一区Q1。第一区Q1设置在镂空孔lk的至少一侧，第二区Q2设置在第一区Q1远离镂空孔lk的至少一侧。支撑板100对应于第一区Q1的部分的刚度小于支撑板100对应于第二区Q2的部分的刚度。
其中，在镂空孔lk的至少一侧设置具有开口kk的第一区Q1，通过设置开口kk来降低第一区Q1的刚度，进而在进行模组压合时，提高第一区Q1部分的应力释放效果，从而降低支撑板100上的镂空孔lk周围存在印痕的风险。
另外，镂空孔lk的孔壁位于开孔mk的孔壁的外周侧的设置，能提高释放压应力的效果，从而进一步缓冲和降低压痕的问题。
可选的，镂空孔lk的孔径和开孔mk的孔径之差值介于1.2毫米至3毫米之间，比如可以是1.2毫米、2毫米或3毫米。
