Description

显示模组及具有该显示模组的电子装置 技术领域
本发明涉及显示模组，尤其涉及一种可视面积的比例较大的显示模组。
背景技术
液晶显示器(LCD)面板的构造是在两片平行的刚性方形玻璃基板当中放置液晶，下基板玻璃上设置薄膜晶体管(TFT)，上基板玻璃上设置彩色滤光片，通过TFT上的信号与电压改变来控制液晶分子的转动方向，从而达到控制每个像素点偏振光出射与否而达到显示目的。由于液晶为液态，上下玻璃基板的四周均需设置密封装置，如密封胶以密封液晶，这导致液晶面板的四周均有无法显示图线的边框。
随着技术的发展，出现了有机发光二极管(OLED)面板，其包括设置在刚性玻璃基板上的两层电极以及夹设在两者之间的一层有机材料。由于有机材料不会随意流动，因此无需设置边框进行密封。现有的一种OLED面板具有位于中间的矩形有效显示区域以及位于四周的用于将有效显示区域内的控制线及数据线连接至对应的控制器的布线区域。由于布线区域不具显示功能，因此，该OLED面板的有效显示区域与整个面板的比例，即可视面积的比例依然较低。近来柔性OLED屏幕的出现使得进一步提升上述可视面积的比例出现较大的发展空间。
发明内容
本发明的实施方式提供了一种使用柔性屏幕的可视面积的比例较大 的显示模组。
一种显示模组，包括基板及柔性屏幕。该基板包括具有第一曲率的正面、与该正面背对的背面以及位于该正面侧边的具有第二曲率的侧面，该第二曲率大于该第一曲率。该柔性屏幕包括无显示区域及具有发光元件阵列的有效区域，该有效区域包括与该正面贴合的主体部以及与该侧面贴合的边缘部，该无显示区域至少部分延伸至该背面。
本发明还提供了一种显示模组，包括刚性透明板及柔性屏幕。该刚性透明板包括具有第一曲率的本体以及位于该本体侧边的具有第二曲率的侧边，该第二曲率大于该第一曲率。该柔性屏幕包括无显示区域及具有发光元件阵列的有效区域，该有效区域包括与该本体贴合的主体部以及与该侧边贴合的边缘部，该无显示区域至少部分与该有效区域重合。
本发明还提供一种具有上述显示模组的电子装置。
本发明中，用户能看到的显示模组的边缘均可显示图像，没有边框，因此，显示模组的可视面积的比例得到提升。当显示模组被组装在手机中等电子装置中时，手机两侧边缘可以设计成没有边框，提升了手机的吸引力。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合多个实施方式及附图，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不用于限定本发明。并且，其显示不代表本发明各元件的实际比例关系，仅做示意。
结合图1及图2，其是本发明第一实施方式提供的显示模组10的组装前后的示意图。显示模组10包括一个基板20、一个柔性屏幕30以及一个集成控制器40。基板20呈长方形，包括正面22、与正面22背对的背面24、及沿基板20的长边方向延伸的两个侧面26。正面22及背面24为相互平行的平面。各侧面26为半圆柱面并与正面22及背面24相切，该特征在图5中显示得更明显。基板20的长度为L，宽度(两个侧面26的最远距离)为W。
请结合图3及图4，柔性屏幕30展开时呈方形，其包括具有发光元件阵列31的方形有效区域36以及无显示区域38。有效区域36的长度为L，宽度大于W。发光元件阵列31包括相互正交的栅极线32和数据线33、 设置在相邻的栅极线32和相邻的数据线33之间的控制电路34、以及与对应的控制电路34连接的发光单元35，如有机发光二极管。控制电路34与对应的栅极线28和数据线26连接，以接收对应的控制指令，从而控制发光单元35的开启或关闭。栅极线32的基数行及偶数行分别延伸至无显示区域38位于有效区域36与基板20的长边的方向平行的相对两侧(图中标号分别为38a及38b)，并进一步延伸至无显示区域38与基板20的长边的方向垂直的一侧(图中标号为38c)。数据线33同样自有效区域36延伸至无显示区域38c。集成控制器40设置在无显示区域38c，并与上述栅极线32及数据线33连接。集成控制器40用于发出上述指令。集成控制器40的长度可以比有效区域36在垂直于基板20长边的方向上的长度短，此时上述栅极线32及数据线33向中间靠拢以与集成控制器40连接。
组装时，将有效区域36与基板20的正面22的中点对齐，并使两者的长边相互平行，然后将无显示区域38a及38b沿侧面26分别向背面24弯折，并可通过粘合等方式固定至背面24，便形成了图1所示的结构。如图5所示，有效区域36覆盖了基板20的正面22以及侧面26弧长的一半。如此，有效区域36包括了与正面22贴合的主体部36a以及与侧面26贴合的边缘部36b。如图2所示，此时无显示区域38c位于基板20之外。如此，沿正面看组装后的显示模组10，显示模组10的三个边缘均可显示图像，没有边框，仅设置有集成控制器40的无显示区域38c可见，显示模组10的可视面积的比例得到提升。当显示模组10被组装在手机中时，手机两侧边缘可以设计成没有边框，提升了手机的吸引力。当然，显示模组10也可应用于平板电脑、电脑一体机、显示器、电视等电子装置中。可以理解，显示模组10也可以使正方形或者其它形状，可根据具体电子装置 的需求而定。可以理解，第一及第二边缘部36b，36c也可覆盖小于或大于第一及第二侧面26，28弧长的一半，可根据具体电子装置的设计而定。
请结合图6及图7，其是本发明第二实施方式的显示模组10’，其与第一实施方式的显示模组10的区别在于，柔性屏幕30’的栅极线32均向与基板20的长边的方向平行的无显示区域38b延伸，并进一步延伸至无显示区域38c。无显示区域38b延伸至基板的背面，与其相对的有效区域的边缘部仍贴合至侧面而弯曲。此种实施方式中，同样能达到第一实施方式所达到的三个边缘均可显示图像的效果。
图8是本发明第三实施方式的显示模组10”，其与第二实施方式的显示模组10’的区别在于，基板20”的侧面仅一侧为半圆柱面，另一侧26’为平面。有效区域36与无显示区域38b相对的一侧36b’与该平面26’对齐，即是说，有效区域36仅包括一个与侧面26贴合的边缘部36b。
可以理解，无显示区域38a及38b中也设置有采用阵列基板行驱动技术(Gate driver on Array，GOA)等技术制作在发光元件阵列的阵列基板上的栅极驱动器。
可选地，请结合图9，上述第一至第三实施方式的基板也可以是一个刚性的可变形后保持形状的平板，如较薄的钢板27弯曲而成。此时，钢板可形成半包围结构，其中空的腔体29可用于收容其它部件，比如收容应用该显示模组的电子装置的电路板。
可选地，上述第一至第三实施方式的基板可以由电池充当，此时可将电池设计成对应的实施方式所示的基板的形状。此时可以降低应用该显示模组的电子装置的厚度。
可选地，以上列举的各实施方式中的基板可以是弯曲的，设置有柔性屏幕的正面22可以一定的曲率下凹，如图10所示。当然，也可以一定的 曲率上凸(图未示)，或者是大致呈球面状的下凹或上凸，总之，可以是凹面或是凸面，而且该下凹或上凸的曲率小于侧面的曲率。另外，该侧面也不一定得是与该正面及背面相切的半圆柱面，只要其与该正面或背面平滑地连接过渡，以免柔性屏幕受到较锐利的角度的损伤便可。由于正面为平面时其曲率为零，因此，结合以上所有的实施方式可知，只要基板正面的曲率比基板侧面的曲率小便都是在本发明精神的涵盖范围内。
优选地，以上列举的各实施方式中，柔性屏幕30背对基板20的表面还可设置具有感知触摸功能的触摸层(图未示)。
请结合图11，其是本发明又一实施方式的显示模组12的剖视示意图。本实施方式的显示模组12与第一实施方式的显示模组10的不同之处在于，不包括基板20，而是包括与柔性屏幕30背对原来的基板20的表面接触的刚性透明板50。刚性透明板50可以是刚性并且透明的玻璃、陶瓷或塑胶等，其包括长方形的平面本体52以及两个分别连接至本体52的长边的弯曲侧边54，侧边54可弯成1/4圆弧状。柔性屏幕30的有效区域36通过粘合等方式固定至刚性透明板50，如通过光学胶(Optical Clear Adhesive，OCA)，并使得有效区域36主体部36a与本体52贴合，边缘部36b与侧边54贴合。刚性透明板50未与柔性屏幕30贴合的一侧为朝向用户的一侧。无显示区域可在后续显示模组12组装入电子装置时再进行固定，并连接至对应的电路，并且，无显示区域38至少部分与有效区域36重合。需支出的是，上述“重合”并无限定两者直接重叠的意思，如图11所示，是指无显示区域38至少部分投影在有效区域36内。当刚性透明板50为电子装置面向用户的最外层的玻璃板时，相对于以上实施方式，其无需设置基板，可进一步降低电子装置的厚度。
当要使显示模组具备触摸功能时，可在柔性屏幕30与刚性透明板50 之间设置具备感知触摸功能的触摸层，以实现触摸功能。具体地，可先将触摸层通过OCA粘接至柔性屏幕30，再讲触摸层通过OCA粘接至刚性透明板50。
可以理解，上述多个实施方式中列举过能用到本实施方式的变形，本实施方式也能进行对应的变形。比如，将本体52设置成弯曲，将边缘部36b设置成一个等。
具体地，请结合图12，其给出了显示模组12应用在电子装置60，如手机中时的结构示意图。电子装置60的电路板62可设置在显示模组12下方，并且至少部分被显示模组12包围，显示模组12的无显示区域弯曲至电路板62并与其连接，电池64位于电路板下方。显示模组12的刚性透明板50构成电子装置供用户操作的前面板。
以上所述仅为本发明的较佳实施方式而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
