技术领域
本发明涉及液晶显示技术领域，尤其是涉及一种胶带、背光模组及液晶显示装置。
背景技术
背光模组是位于液晶显示装置背后的一种光源，其发光效果将直接影响到液晶显示模块的视觉效果。液晶面板是被动发光元件，显示面板本身不发光，而是由其下方的背光模组照亮的，作为液晶显示装置的关键零组件之一的背光模组，主要功能是向液晶显示提供充足的亮度和均匀分布的光源，使得液晶显示装置能够正常显示影像。随着液晶显示技术的不断发展与创新，液晶显示朝着超薄窄边框的方向发展，相应地，对背光模组也提出了更高的技术要求。
如图1所示，现有技术的背光模组90一般包括边框91、胶框92、反射片93、导光板94、光学膜片95以及胶带96，其中，胶带96具有遮蔽光线和固定等作用。随着液晶显示朝着超薄窄边框方向发展，对胶带96的要求也越来越高。但是现有技术中的胶带96在应用时，由于边框91和胶框92变窄，而使得胶带96也随之变窄而最终导致胶带96不容易裁切。即便是在裁切粘附完成后，窄的胶带96也容易发生翘曲等问题。
发明内容
针对现有技术中所存在的上述技术问题，本发明提出了一种胶带、背光模组及液晶显示装置。该胶带能应用于背光模组，具有容易裁切，能增大粘附面积，以使其不易发生翘曲，提高粘结稳定性等优点。
根据本发明的第一方面，提出了一种胶带，包括：
窄侧边，窄侧边具有能遮光的第一部分和能透光的第二部分，其中，第二部分能侧向延伸出第一部分。
在一个实施例中，第一部分和第二部分包括由PET材料整体制造而成的透明的基层材料 层。
在一个实施例中，第一部分还包括设置在基层材料层上的遮光层。优选地，遮光层通过喷墨或刻蚀制成。
在一个实施例中，第一部分的宽度与第二部分的宽度比为0.5∶1-2∶1。
在一个实施例中，还包括宽侧边，宽侧板能够与窄侧边组成框形结构，在宽侧边和窄侧边的上下表面上均设置压敏胶，其中，设置在第二部分的压敏胶为透光性压敏胶。
在一个实施例中，在压敏胶的外表面设置离型膜层。
根据本发明的第二方面，提供一种背光模组，其包括光源和胶带，胶带的宽侧边位于背光模组的光源一侧，窄侧边位于背光模组的另外侧边。
在一个实施例中，背光模组还包括：
形成容纳腔的边框，
设置在容纳腔底面上的反射片，
设置在反射片上的导光板，
设置在导光板上的光学膜片，
其中，光源设置在反射片上，并位于导光板的一侧。
根据本发明的第三方面，提供一种液晶显示装置，其包括背光模组。
与现有技术相比，本发明的优点在于，该胶带的窄侧边在宽度方向上具有第一部分和第二部分，其中第二部分能透光可搭接在光学膜片上，可增加胶带的使用宽度。由此，根据本发明的胶带降低了胶带的裁剪难度，增加了胶带的粘附稳定性。
附图说明
下面将结合附图来对本发明的优选实施例进行详细地描述。在图中：
图1显示了现有技术中的背光模组的结构图。
图2显示了根据本发明的胶带的结构图。
图3显示了来自图2的A-A剖面图。
图4显示了根据本发明的背光模组的结构图。
图5显示了根据本发明的液晶显示装置。
在附图中，相同的部件使用相同的附图标记。附图并未按照实际的比例绘制。
具体实施方式
下面将结合附图对本发明做进一步说明。
图2显示了根据本发明的胶带10。如图2所示，胶带10窄侧边12。胶带10窄侧边12还可以包括宽侧边11，以与窄侧边12一起组成用于匹配背光模组的边框结构。窄边框12具有第一部分13和第二部分14。其中，第一部分13能够遮光，第二部分14能够透光。并且，第二部分14能够侧向延伸出第一部分13，以增加胶带10的窄侧边12的宽度。
需要说明的是，本实施例中所述的宽侧边11与窄侧边12是相对比较得出的，即宽侧边11为在所有侧边中宽度最大的侧边，窄侧边12为宽度小于宽侧边11的宽度的侧边。
由此，在将胶带10设置在背光模组的边框上时，胶带10的贴附于背光模组的边框内并位于光学膜片的上方，且胶带10的宽侧边11位于背光模组的光源侧，以避免背光模组漏光。而窄侧边12位于背光模组的非光源侧。同时，窄侧边12的第二部分14可以延伸到光学膜片的表面上，而不影响背光模组向液晶面板提供充足的亮度和均匀分布的光源。通过第二部分14可以增加胶带10本身的宽度，以增加与边框的贴附面积，有效避免了现有技术中的胶带10的宽度受限于边框宽度过窄导致的裁切困难或者贴附后容易翘曲的问题。
需要说明的是，胶带10的侧边个数可以根据实际情况而定，也就是，其根据实际生产需要而配合背光模组的边框的形状。本申请中，只是以矩形的胶带10为例而解释。
根据本发明，第一部分13和第二部分14包括透明的基层材料层15，如图3所示。第一部分13和第二部分14的基层材料层15可作为一整体制造而成。例如，基层材料层15可由PET材料或亚克力材料制成。
第一部分13还包括设置在基层材料层15上的遮光层19，以用于遮蔽光线。优选地，遮光层19可通过喷墨或刻蚀等工艺制成。具有此结构的胶带10本身结构简单，制造容易。
根据本发明，为保证胶带10的遮光效果，同时又使其不影响背光模组的透光效果，第一部分13宽度与第二部分14的宽度比为0.5∶1-2∶1。例如，第一部分13宽度与第二部分12的宽度比为1∶1。由此，通过这种设置，可以提高胶带10与边框的粘附面积，而不影响背光模组向液晶面板提供充足的亮度和均匀分布的光源，以致不影响液晶显示装置的显示品质。同时，这种设置有利于顺利进行粘附胶带10的工序，提高生产制造背光模组的效率。另外，这种设置能提高粘附面积，从而保证粘结稳定性。且在保证粘附面积的同时，优化了胶带10的结构，避免浪费生产胶带10的原材料，节约了成本。
在一个实施例中，在宽侧边11和窄侧边12的上下表面上均设置压敏胶16。在使用胶带10时，压敏胶16的一面与背光模组的边框贴合，另一面与液晶面板贴合，进而固定连接液晶面板和背光模组。并且处在第二部分14处的压敏胶16是光学上高透光的胶粘剂，以使得压敏胶16并不影响第二部分14处的光线的传播。优选地，压敏胶16可为丙烯酸胶粘剂，且整体式涂覆在宽侧边11和窄侧边12的上下表面上。
进一步地，为了防止压敏胶16的表面受到污染，影响其粘性。可在压敏胶16的外表面设置离型膜层17。离型膜层17用于保护压敏胶16。需要粘贴时，则将离型膜层17撕除后进行粘贴。同时，设置离型膜层17使得胶带10能盘卷设置，方便于存放和搬运。另外，在离型膜层17上还具有延伸出压敏胶16的突出部18。拽拉突出部18能方便地撕除离型膜层17。
为了进一步提高胶带10的遮光效果，在第一部分13朝向背光模组光源侧的一面设置有反射层(图中未示出)。通过反射层可以将照射到胶带10的光线反射到导光板上，避免了光线的损失，提高了背光模组的光学效果。
本发明还提供了一种采用上述胶带10的背光模组100。如图4所示，背光模组100包括边框20、反射片21、导光板22、光源(图中未示出)、光学膜片23和胶带10。其中，反射片21卡接式设置在边框20组成的容纳腔24的底面上。导光板22设置在反射片21上。光源设置在反射片21上，并位于导光板22的一侧。而光学膜片23设置在导光板22上。胶带10的宽侧板11位于背光模组100的光源一侧，窄侧边12位于背光模组100的另外侧边。由于胶带10由第一部分13和第二部分14组成，而第二部分14能透光，可伸入粘结到光学膜片23的表面上。由此，可增加胶带10与边框20和光学膜片23的粘结面积，从而防止现有技术中的胶带过窄容易翘曲等问题，有助于提高背光模组100的粘结稳定性。同时，此种结构的胶带10的宽度不受限与边框20的宽度，而能通过第二部分14向第一部分13的侧向延伸而增加胶带10本身的宽度，从而能设置为较宽的胶带10容易裁切，且本身的宽度有助于进行粘结等工序。具有此种结构的胶带10能不限定背光模组100的边框20的宽度，从而有助于实现窄边框化。
需要说明地是，较佳地，边框20为铁壳，即边框20采用金属铁为材质，但不以此为限，边框20也可以采用其它材质制作而成。
根据本发明还提供一种液晶显示装置200，如图5所示。液晶显示装置200包括液晶面板150和背光模组100。液晶面板150通过胶带10粘结到背光模组100上。所述液晶显示装置可以为液晶电视、液晶显示器、数码相框、手机、平板电脑等任何具有显示功能的产品或部件。
以上所述仅为本发明的优选实施方式，但本发明保护范围并不局限于此，任何本领域的技术人员在本发明公开的技术范围内，可容易地进行改变或变化，而这种改变或变化都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求书的保护范围为准。
