Description

显示面板组件和显示装置 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种显示面板组件和显示装置。
背景技术
随着显示技术的发展，各式显示装置不断推陈出新。液晶显示装置(LCD，Liquid Crystal Display)具有机身薄、省电、无辐射等优点，广泛应用于移动终端设备中。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括后壳、与后壳配合设置的前壳、设置于后壳内的背光板、设置于背光板上的胶框及设置于胶框上的液晶显示面板，其中胶框配置为承载液晶显示面板，前壳配置为固定液晶显示面板。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，通过玻璃基板通电与否来控制液晶分子改变方向，将背光板的光线折射出来产生画面。
随着液晶显示装置生产技术的不断发展，为了提高用户体验，液晶显示装置的边框越做越窄。市场上的移动终端大部分是采用液晶显示屏，为了使移动终端的显示屏尺寸增大，而移动终端的尺寸不与显示屏尺寸成比例增大，便需要将移动终端的显示屏边框做小，甚至做到无边框的显示效果。

具体实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，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例仅仅用以解释本发明，并不用于限定本发明。
图1所示为本发明实施例提供的显示面板组件的局部剖面结构示意图，图2、图3为本发明实施例提供的显示装置的结构示意图，图4为本发明实施例提供的显示装置的显示光线折射图。本发明的显示面板组件应用于显示装置，尤其适用于无边框显示装置，以下将以显示面板组件应用于无边框显示装置为例，对本发明的显示面板组件和显示装置进行详细说明。本 发明的显示装置可以是任意显示设备，如可以是手机、平板电脑、数码相机等移动终端，也可以是电视、显示器等显示终端，本发明实施例以显示装置为移动终端为例进行说明。
如图1至图4所示，所述无边框显示装置包括中框150和设置于中框150内的显示面板组件，其中，显示面板组件包括设置于中框150内的显示屏130、设置于显示屏130上方的透明盖板110以及设置于显示屏130下方的背光板140，透明盖板110与显示屏130之间设有显示区120。由于图1、图3和图4为剖面结构示意图，因此后续对于线条的描述，比如边，其实是一个面，可以为本领域技术人员毫无疑义地所理解。
中框150包括主板151和侧板152，主板151在一种实施方式中为具有平面结构的板材，当然也不局限于严格的平面结构，不平坦的结构也可以。主板151与侧板152之间衔接，形成收容空间。主板151的边缘以一定的角度(比如钝角，直角，或者锐角等)向外进行延伸得到侧板152。前面描述的“主板151的边缘以一定的角度向外进行延伸得到侧板152”为一种形象描述，不应理解为侧板152的实际形成方法，当然侧板152的实际形成方法也不局限于此。所述收容空间配置为放置或收容显示屏130和背光板140。主板151和侧板152可以一体成型，或者二者之间通过卡扣、螺丝、胶粘接或者其他方式连接在一起。
侧板152包括倒边1521，比如折线边、弧边、或者如图3所示的斜边。所述侧板152包括临近显示屏130的边和远离显示屏130的边，临近显示屏130的边和远离显示屏130的边相互平行，或者不局限于严格的平行。倒边1521的两端分别与临近显示屏130的边和远离显示屏130的边相交，或者，如图3所示，倒边1521的一端与远离显示屏130的边相交，倒边1521的另一端的延长线与临近显示屏130的边相交。
显示屏130和背光板140设置于中框150内，也即显示屏130和背光 板140放置于主板151与侧板152形成收容空间之中。作为一种实施方式，显示屏130包括依次相邻设置的触控面板131和液晶面板132。液晶面板132也可以替换成有机发光二极管(OLED，Organic Light-Emitting Diode)面板、电润湿面板等显示面板。另外，显示屏130也可以仅具有显示功能，而不需要具有触控功能，即显示屏130可以只包括液晶面板132。
透明盖板110设置于显示屏130上方，也即透明盖板110、显示屏130、背光板140和中框150的主板151依次相邻。作为一种实施方式，透明盖板110也全部或者部分放置于主板151与侧板152形成收容空间之中；当然，透明盖板110也可以在主板151与侧板152形成收容空间之外。在图3至图4的示意图中，透明盖板110部分放置于主板151与侧板152形成收容空间之中。另外，透明盖板110可以由玻璃、或者塑料等材质制成。
透明盖板110的边缘为倒角，呈现折线边，斜边，或者例如图1和图3所示的圆弧边111，或者多种类型的组合，换句话说，倒角可以为斜倒角和圆倒角中的一种或二者的组合。如图1和图3所示，透明盖板110包括相互平行的两条边(当然这两条边也不局限严格的平行)，其中一条边相较于另一条边更接近显示屏130。透明盖板110远离显示屏130的一条边开始弯折形成圆弧延续到接近显示屏130的一条边，从而形成圆弧边111，换句话说，透明盖板110的上表面在边缘位置往透明盖板的下表面方向弯折延续而形成一倒角，倒角在一种实施方式中为圆倒角。前面描述的“开始弯折形成圆弧”为一种形象描述，不应理解为圆弧边111的实际形成方法，当然圆弧边111的实际形成方法也不局限于此。又如，透明盖板110远离显示屏130的一条边开始弯折形成圆弧延续到接近显示屏130的一条边时，从圆弧转变为直线或折线，再与接近显示屏130的一条边相交，从而形成圆弧边111与直线(或折线)组合的倒角。而从圆弧转变成的直线或折线与侧板152抵接，正是具有这一段的接触(相较于点接触，或者线接触，这 一段的面接触)，能够很好实现透明盖板110与中框150之间的固定。即，该倒角包括圆弧段和直线段，圆弧段高于侧板，直线段抵接侧板。
以中框150的主板151为参考基准，透明盖板110的高度，大于侧板152的高度。
透明盖板110的圆弧边111和侧板152的倒边1521之间渐进扩展的延续结构设计，或者斜坡设计，使得产品的设计符合工业设计的美感，也使得用户在触摸或者握持的时候，为圆润或者润滑的接触体验，没有尖角刺碰的非良好体验。
作为一种实施方式，透明盖板110的倒角上至少一点的切线经过侧板142的倒边，换句话说，圆弧边111的某一点的切线经过侧板152的倒边1521。
请参阅图1和图3，显示屏130提供显示区120和在显示区120之外的非显示区。为了便于进行本发明的解释，图1和图3中的显示区120仅仅一示意图，非结构模块。显示区120设置于透明盖板110与显示屏130之间，显示屏130与背光板140之间设有遮光板160，遮光板160覆盖背光板140的周缘，并遮住显示区120与侧板152之间的缝隙。遮光板160的宽度大于或者等于缝隙的宽度，只要使背光板140发出的显示光线不会从显示区120与侧板152之间的缝隙漏出去即可。
作为一种实施方式，侧板152内侧设有配置为承载显示屏130和透明盖板110的凸缘1522，遮光板160设置于凸缘1522与显示屏130之间，覆盖背光板140的周缘，并抵接侧板152，即遮光板160右端与侧板152上接近显示屏130的边抵接，防止漏光。
如图4所示，在液晶面板132允许光线穿过的情况下，背光板140产生的光线，先经过液晶面板132和触控面板131，再穿过透明盖板110，一部分光线沿着透明盖板110垂直线方向射出，另一部分光线随透明盖板110 的圆弧边111发生折射，从圆弧边111射出，因为圆弧边111的设计从而拉大显示区120，并且，中框150顺着圆弧边111的方向设有倒边1521，因此从正面垂直透明盖板110的方向看，整个透明盖板110的延伸方向都是可视区域，即显示屏130的显示范围一直延伸至移动终端显示屏130的边缘，从而实现显示无边框的效果，提高用户体验度。而设置于显示屏130与背光板140之间并覆盖背光板140周缘的遮光板160，配置为遮住背光板140周缘发出的显示光线，避免光线从显示区120与侧板152之间的缝隙射出，使得用户在观看时不会产生眩晕的感觉，增强用户使用的舒适感，同样提高了用户体验。
本发明实施例提供的无边框显示装置1，请参阅图3至图4，在前面技术方案的基础上，作为一种实施方式，主板151与侧板152相互垂直。主板151承载组装于中框150内的背光板140，侧板152配置为固定显示屏130和背光板140，或者配置为固定显示屏130、背光板140和透明盖板110。
本发明实施例提供的无边框显示装置1，请参阅图3至图4，在前面技术方案的基础上，作为一种实施方式，主板151与侧板152一体成型，一体成型不但稳固并且无粘接处外观更加漂亮。
本发明实施例提供的无边框显示装置1，请参阅图3至图4，在前面技术方案的基础上，作为一种实施方式，显示屏130包括液晶面板132和设置于液晶面板132上方的触控面板131。
本发明实施例提供的无边框显示装置1，请参阅图1、图3和图4，在前面技术方案的基础上，作为一种实施方式，背光板140的宽度大于显示区120的宽度，背光板140的宽度小于显示屏130的宽度。背光板140大于显示区120的宽度部分用遮光板160挡住外射光线，避免漏光造成用户观看时产生眩晕的感觉，提高用户使用舒适度和体验度。
本发明实施例提供的无边框显示装置1，请参阅图1、图3和图4，在 前面技术方案的基础上，作为一种实施方式，显示区120的宽度大于或等于透明盖板110的上表面的宽度。这里所说的透明盖板110的上表面指的是透明盖板110上表面的平面部分，不包括圆弧边111部分。
本发明实施例提供的无边框显示装置1，请参阅图1、图3和图4，在前面技术方案的基础上，作为一种实施方式，遮光板160的材质为黑胶。黑胶具有低线膨胀系数及耐高温的特性，在光线的长时间照射下也不会发生变形。
本发明实施例提供的无边框显示装置1，请参阅图2至图4，在前面技术方案的基础上，作为一种实施方式，中框150的材质是金属或者塑胶，例如铜(Cu)、铝(Al)、钢、不锈钢或镁(Magnesium)。
上述实施例的显示面板组件和无边框显示装置1，透明盖板110的边缘为圆弧边111，背光板140射出的光线随透明盖板110的圆弧边111发生折射，并从圆弧边111位置射出，从而拉大了显示区120域，无边框显示装置的中框150顺着圆弧边111的方向设有倒边1521，使用户从屏幕的正面垂直方向观看时，透明盖板110的延伸方向全是可视区，即显示屏130的显示范围一直到达边缘，实现显示效果无边框的目的，而遮光板160遮住背光板140周缘发出的显示光线，避免显示光线从显示区120与侧板152之间的缝隙漏出，使得用户在观看时不会产生眩晕的感觉，增强用户使用的舒适感，同样提高了用户体验。
以上参照附图说明了本发明的优选实施例，并非因此局限本发明的权利范围。本领域技术人员不脱离本发明的范围和实质，可以有多种变型方案实现本发明，比如作为一个实施例的特征可用于另一实施例而得到又一实施例。凡在运用本发明的技术构思之内所作的任何修改、等同替换和改进，均应在本发明的权利范围之内。
工业实用性
本发明实施例通过使透明盖板的边缘为倒角，背光板射出的光线随透明盖板的倒角发生折射，并从倒角位置射出，从而拉大了显示区域，显示装置的中框顺着倒角的方向设有倒边，因此从正面垂直透明盖板的方向看，整个透明盖板的延伸方向都是可视区域，即显示屏的显示范围一直延伸至移动终端显示屏的边缘，从而实现显示无边框的效果；而遮光板遮住背光板周缘发出的显示光线，避免用户观看时产生眩晕感，增强用户使用舒适感和提高体验度。
