盖板及显示屏 技术领域
本申请涉及显示技术领域，具体涉及一种盖板及显示屏。
 背景技术
近年来，随着消费者对护眼、省电的需求日益增加，为满足这一需求，传统的技术方案中通过设置红外传感器测量用户设备与用户面部之间的距离和感应外界光线的亮度，根据用户设备与用户面部之间的距离以及外界光线的亮度调整设备屏幕的亮度，以达到护眼、省电的作用。
传统的用户设备中的显示屏设有红外感应孔，红外感应孔的所在位置也逐渐靠近盖板边缘，红外感应孔处涂有白色油墨，此油墨对可见光有遮蔽作用，但是会让红外线光通过。由于油墨具有流动性，印刷油墨时会存在一定公差，这会导致白色油墨溢到显示面板的盖板边缘，改变光线的折射和反射路径，使得盖板边缘对应红外感应孔的位置附近出现发亮现象。

 本发明的实施方式
下面将结合本申请的实施例中的附图，对本申请实施例中的技术方案进行描述。所描述的实施例仅用于对本申请的思想进行解释和说明，而不应当视为对本申请的保护范围的限制。
本申请实施例提供一种显示屏，包括盖板以及显示面板，盖板贴合在显示面板的出光面。显示面板包括红外传感器。
请参阅图1至图2b，图1是本申请实施例提供的盖板的俯视图；图2a是图1中提供的盖板沿AA’方向的第一种剖视图；图2b是图1中提供的盖板沿AA’方向的第一种俯视图。如图1和图2a所示，本申请实施例提供一种盖板100，包括：盖板本体10、油墨部20以及阻隔部30，盖板本体10具有显示区AA和边框区NA，边框区NA围绕显示区AA设置，且边框区中设有红外感应孔子区IR，红外传感器设于红外感应孔子区IR；油墨部20设于盖板本体10远离发光的一面且位于边框区NA，油墨部20包括白油墨层21，白油墨层21覆盖红外感应孔子区IR；阻隔部30设于边框区NA上且位于红外感应孔子区IR远离显示区AA的一侧，其中，白油墨层21远离所述显示区AA的边界不超出阻隔部30远离显示区AA的边界。
在本申请实施例中，通过在油墨部20以及盖板的边缘之间设置阻隔部30，阻挡红外感应孔边缘的白色油墨溢出到盖板边缘，能够避免光线的折射和反射路径改变，进而避免盖板边缘发亮。
在本申请实施例中，油墨部20还包括第一黑油墨层22以及半透黑油墨层23，第一黑油墨层22设于边框区NA上，且围绕红外感应孔子区IR设置；半透黑油墨层23设于边框区NA上且覆盖红外感应孔子区IR；白油墨层21覆盖半透黑油墨层23。具体的，油墨部设于盖板本体10远离发光的一面。
具体地，半透黑油墨层23用于遮蔽底部结构以及可见光；白油墨层21用于使得透过外感应孔子区IR的光线变成均匀的白光。第一黑油墨层22、半透黑油墨层23以及白油墨层21均包括树脂、固化剂、助剂和溶剂，树脂为油墨主体结构，固化剂用于保证树脂的交联程度和印刷性能，助剂和溶剂用于保证油墨的印刷性能；第一黑油墨层22、半透黑油墨层23和白油墨层21均还包括色素，色素用于调整油墨的颜色，第一黑油墨层22的色素为黑色，半透黑油墨层23的色素为灰色，白油墨层21的色素为白色。
在本申请实施例中，第一油墨区201、第一通孔221以及第二油墨区202沿第一方向X排布，阻隔部30沿第二方向Y的横截面宽度大于油墨部20沿第二方向Y的横截面宽度，第一方向X与第二方向Y相互垂直，优选地，阻隔部30沿第二方向Y的横截面宽度大于白油墨层21沿第二方向Y的横截面宽度。第一方向X指的是显示面板的长度方向，第二方向Y指的是显示面板的宽度方向。
进一步地，阻隔部30沿盖板本体10厚度方向的高度大于或者等于油墨部20的厚度。优选地，如图2a所示，阻隔部30沿盖板本体10厚度方向的高度H1大于油墨部20的厚度H2。这样的设置，有利于将丝印时超出规格的白色油墨阻隔在盖板边缘以内，防止白色油墨溢出到盖板边缘，引起光线的折射和反射路径改变，导致白色油墨反射光相对正常品多，从而导致盖板边缘出现发亮现象。
在本申请实施例中，油墨部20还包括第二黑油墨层24，第二黑油墨层24设于第一黑油墨层22远离盖板本体10的一侧，第一黑油墨层22在红外感应孔子区IR处设有第一通孔221；第二黑油墨层24在红外感应孔子区IR处对应设有第二通孔241，半透黑油墨层23覆盖第一通孔221以及第二通孔241的表面，且部分覆盖第二黑油墨层24。具体地，半透黑油墨层23覆盖第一通孔221以及第二通孔241的底面以及沿第一方向X的两个侧壁，并从侧壁延伸覆盖部分第二黑油墨层24；其中，第一通孔221沿第一方向X的横截面宽度大于或者等于第二通孔241沿第一方向X的横截面宽度。
具体地，第一黑油墨层22以及第二黑油墨层24的材料包括黑色油墨或者深色油墨；第一黑油墨层22以及第二黑油墨层24可以为单层结构或者多层结构，即，第一黑油墨层22可以仅包括一个膜层，也可以包括叠置的至少两个膜层；对应的，第二黑油墨层24可以仅包括一个膜层，也可以包括叠置的至少两个膜层。第一通孔221以及第二通孔241为红外感应孔，半透黑油墨层23以及白油墨层21覆盖在红外感应孔的表面上，用于遮蔽可见光，并让红外线通过。第二黑油墨层24的材料与第一黑油墨层22的材料相同。
在本申请实施例中，阻隔部30包括阻隔槽31，阻隔槽31设于设于边框区NA上且位于红外感应孔子区IR远离显示区AA的一侧。如图2b所示，阻隔槽31沿第二方向Y的横截面宽度W1大于白油墨层21沿第二方向Y的横截面宽度W2；如图2a所示，阻隔槽31沿盖板本体10厚度方向的深度大于油墨部20的厚度。这样的设置，有利于将丝印时超出规格的白色油墨导入阻隔槽31内以将其阻隔在盖板边缘以内，防止白色油墨溢出到盖板边缘，引起光线的折射和反射路径改变，导致白色油墨反射光相对正常品多，从而导致盖板边缘出现发亮现象。图2b中仅示例性的示出阻隔槽31沿第二方向Y的横截面宽度W1与白油墨层21沿第二方向Y的横截面宽度W2之间的尺寸关系，不作为对阻隔槽31沿显示面板厚度方向的形态的限定。
作为本申请的一种具体实施方式，请参阅图3，图3是图1中提供的盖板沿AA’方向的第二种剖视图。如图3所示，本申请实施例提供一种盖板200，盖板200与盖板100的区别在于：阻隔部30包括阻隔栅32，阻隔栅32设于边框区NA上且位于红外感应孔子区IR远离显示区AA的一侧。
在本申请实施例中，阻隔栅32设于盖板本体10远离发光的一面，阻隔栅32的沿盖板本体10厚度方向的截面形状可以为等腰梯形、直角梯形等梯形结构，阻隔栅32的形状包括但不限于四棱柱形、圆柱形、圆台形、半球形。
在本申请实施例中，采用丝印的方式将第一黑油墨层22、第二油墨层24、半透黑油墨层23以及白油墨层21形成在盖板本体10上，并在红外感应孔子区IR远离显示区AA的一侧的位置通过多次印刷第一黑油墨层22或者第二黑油墨层24的方式形成阻隔栅32。即，阻隔栅32的材料与第一黑油墨层22或者第二黑油墨层24的材料相同。
