Description

液晶显示模块及其制作方法、显示装置 技术领域
本公开涉及显示技术领域，具体地涉及一种液晶显示模块(liquid crystal display module，LCM)及其制作方法、显示装置。
背景技术
如图1a所示，液晶显示模块10′通常包括液晶显示面板100′和背光源模块200′。液晶显示面板100′包括阵列基板110′、彩膜基板120′、设置于阵列基板110′和彩膜基板120′之间的液晶130′。背光源模块200′包括(未图示的)光源、导光板、光学膜片等。液晶显示面板100′和背光源模块200′之间利用双面胶带400′粘合以形成液晶显示模块10′。通常四个侧边都设置有双面胶带400′。
如图1b的局部放大图所示，双面胶带400′通常具有一定宽度W′，为固定液晶显示面板100′和背光源模块120′提供所需的粘合强度。受切割工艺限制，双面胶带400′的宽度W′通常最小值为0.8mm。此外，双面胶带400′的宽度W′通常应不小于0.8mm以提供所需的粘合强度。因此，受双面胶带400′宽度W′的限制，液晶显示模块10′的边框宽度难以小于0.8mm。
因此，本领域中存在对一种改进的液晶显示模块的需求。
发明内容
本公开提出了一种液晶显示模块及其制作方法、显示装置，从而减轻或解决前文所提到的问题的一个或多个。具体而言，本公开提供了一种替代双面胶带的方案以实现液晶显示模块的各面板之间的牢固粘合，并且有利于减小液晶显示模块的窄边宽度。
在第一方面，本公开提供了一种液晶显示模块，包括液晶显示面板和背光源模块，其中所述液晶显示面板和所述背光源模块的至少一个侧边在外表面利用粘合剂固定。
根据本公开，在液晶显示模块中，液晶显示面板和背光源模块的至少一个侧边在外表面应用粘合剂，从而实现二者之间的牢固粘合。由于在侧边的外表面利用胶合剂粘合固定液晶显示面板和背光源模 块，因此不需要采用双面胶带粘合。即，本公开提供了一种替代双面胶带的方案，该方案可以实现液晶显示面板和背光源模块之间的牢固粘合。附加地，根据本公开，由于不使用双面胶带，液晶显示模块的边框宽度不再受限于双面胶带的宽度，并且通过控制胶合剂的厚度可以减小液晶显示模块的边框宽度。
优选地，所述粘合剂可以被应用在所述液晶显示面板和所述背光源模块的四个侧边的外表面上。
根据本公开，在液晶显示模块中液晶显示面板和背光源模块的四个侧边都应用粘合剂，由此可以实现液晶显示面板和背光源模块之间的牢固粘合。此外，通过控制胶合剂的厚度，可以减小液晶显示模块在四个侧边的边框宽度。
优选地，所述粘合剂可以被应用在所述液晶显示面板和所述背光源模块的一个侧边、两个侧边或三个侧边的外表面。
根据本公开，可以根据液晶显示模块的设计需要，在液晶显示面板和背光源模块的相应侧边应用胶合剂，从而实现液晶显示面板和背光源模块之间的牢固粘合。此外，通过控制胶合剂的厚度，可以减小液晶显示模块在相应侧边的边框宽度。
优选地，在所述液晶显示面板和所述背光源模块的未应用所述粘合剂的侧边，双面胶带可以被应用在所述液晶显示面板和所述背光源模块之间。
根据本公开，可以使用现有工艺中的双面胶带，并且可以将双面胶带应用在液晶显示面板和背光源模块的未应用粘合剂的侧边。也就是说，本公开并不排斥使用双面胶带。根据本公开，粘合剂和双面胶带相结合，有利于进一步提高液晶显示面板和背光源模块之间的粘合强度。
优选地，所述液晶显示面板可以包括阵列基板和彩膜基板，所述液晶显示面板经由所述阵列基板固定到所述背光源模块；以及在所述液晶显示面板的所述阵列基板延伸超出所述彩膜基板的侧边，所述双面胶带被应用在所述阵列基板和所述背光源模块之间。
根据本公开，在阵列基板延伸超出彩膜基板的侧边，双面胶带被应用在阵列基板和背光源模块之间。在液晶显示模块中，阵列基板可以在一个或多个侧边延伸超出彩膜基板。即，在与该一个或多个侧边 垂直的方向上，阵列基板的宽度大于彩膜基板的宽度。在该一个或多个侧边，阵列基板比彩膜基板宽的***区域可以充当例如柔性印刷电路板(flexible printed circuit，FPC)连接区域或者驱动IC绑定区域。液晶显示模块因而在该一个或多个侧边的边框宽度通常对是否使用双面胶带以及双面胶带的宽度不敏感。鉴于此，优选地在该一个或多个侧边，在阵列基板和背光源模块之间应用双面胶带，从而进一步提高粘合强度。
优选地，所述粘合剂可以为UV固化粘合剂、热固性粘合剂或热塑性粘合剂。
根据本公开，UV固化粘合剂、热固性粘合剂或热塑性粘合剂都可以用于粘合固定液晶显示面板和背光源模块。也就是说，本公开对胶合剂无特殊限制。这有利于降低液晶显示模块的制作成本。
优选地，所述粘合剂可以为黑色的。
根据本公开，可以根据具体设计需求而选择粘合剂的颜色。在黑色粘合剂被用于粘合固定液晶显示模板和背光源模块的情况下，该黑色粘合剂不透光，由此防止液晶显示模块的漏光现象。粘合剂也可以是其它暗色。
优选地，所述粘合剂的厚度可以为0.05-0.5mm。
根据本公开，粘合剂的厚度通常为0.05-0.5mm，并且可以根据具体设计需求确定粘合剂的厚度。受设备精度影响，通常难以实现低于0.05mm的粘合剂厚度。相反，当粘合剂厚度大于0.5mm时，不利于实现窄边框的液晶显示模块。通过控制粘合剂的厚度，例如控制在0.05-0.1mm的范围，可以有效地减小液晶显示模块的边框宽度，实现窄边框的液晶显示模块。根据本公开，当使用粘合剂替代双面胶带时，液晶显示模块的边框宽度不再受限于双面胶带的宽度，而是受限于液晶显示面板的***非显示区域的宽度、粘合剂的厚度等因素。假设***非显示区域的宽度为0.5mm，当粘合剂的厚度为0.05-0.1mm时，液晶显示模块的边框宽度则为0.55-0.6mm，显著低于采用双面胶带时的边框宽度下限0.8mm。
优选地，所述粘合剂的厚度可以为0.1mm。
根据本公开，粘合剂的厚度为0.1mm时就可以提供足够的粘合强度，从而实现液晶显示面板和背光源模块之间的牢固粘合。粘合剂的 厚度可以根据具体设计需求确定，而不一定限于某一特定厚度。
在第二方面，本公开提供了一种显示装置，其包括如上所述的液晶显示模块。
在第三方面，本公开提供了一种液晶显示模块的制作方法，包括：
在待粘合的液晶显示面板和背光源模块的至少一个侧边的外表面应用粘合剂；以及
固化所述粘合剂，从而固定所述液晶显示面板和所述背光源模块以形成所述液晶显示模块。
优选地，在应用粘合剂的步骤之前，所述方法还可以包括：
在所述液晶显示面板和所述背光源模块的将不应用所述粘合剂的侧边，在所述液晶显示面板和所述背光源模块之间应用双面胶带。
优选地，所述液晶显示面板可以包括阵列基板和彩膜基板，并且应用双面胶带的步骤可以包括：
在所述液晶显示面板的所述阵列基板和所述背光源模块之间应用所述双面胶带。
优选地，应用双面胶带的步骤可以包括：
在所述阵列基板的延伸超出所述彩膜基板的侧边，在所述阵列基板和所述背光源模块之间应用所述双面胶带。
优选地，所述粘合剂可以为UV固化粘合剂、热固性粘合剂或热塑性粘合剂。
优选地，所述粘合剂可以为黑色的。
优选地，在固化之后所述粘合剂的厚度可以为0.05-0.5mm。
根据本公开的液晶显示模块的制作方法以及显示装置具有与前文所述的液晶显示模块相同或相似的益处，此处不再赘述。
根据本公开，使用应用于液晶显示面板和背光源模块的至少一个侧边的外表面的粘合剂，替代传统液晶显示模块中应用于液晶显示面板和背光源模块之间的双面胶带。由此提供了一种新颖的用于牢固地粘合液晶显示面板和背光源模块的方案。此外，根据本公开，由于不使用双面胶带，液晶显示模块的边框宽度不再受限于双面胶带的宽度，并且通过控制胶合剂的厚度可以减小液晶显示模块的边框宽度。
在本公开的上下文中，双面胶带的″宽度″指的是，在液晶显示面板的平面内，在与双面胶带延伸方向垂直的方向上该双面胶带的尺寸。 在液晶显示模块中，双面胶带通常是沿着液晶显示面板的周缘布置在液晶显示面板的表面上。即，双面胶带的延伸方向通常为与液晶显示面板的各个侧边平行的方向。因此，双面胶带的″宽度″也指，在液晶显示面板的平面内，在与液晶显示面板的各个侧边垂直的方向上该双面胶带的尺寸。
在本公开的上下文中，粘合剂的″厚度″指的是，在液晶显示面板的平面内，在与液晶显示面板或背光源模块的侧边的外表面垂直的方向上该粘合剂的尺寸。在本公开中，粘合剂应用在液晶显示面板和背光源模块的至少一个侧边的外表面。因此，粘合剂的″厚度″也指，在液晶显示面板的平面内，在与液晶显示面板的各个侧边垂直的方向上该粘合剂的尺寸。
在本公开的上下文中，液晶显示模块的″边框宽度″指的是，在液晶显示模块或液晶显示面板的平面内，在与各个侧边垂直的方向上从有效显示区域的最外侧到液晶显示模块或液晶显示面板的最外侧的距离。

具体实施方式
下面结合附图，对本公开的液晶显示模块及其制作方法、显示装置的具体实施方式进行详细地说明。本公开的各附图示意性地绘示出与发明点有关的结构、部分和/或步骤，而没有绘示或者仅仅部分地绘示与发明点无关的结构、部分和/或步骤。
各附图中，附图标记：10′液晶显示模块；100′液晶显示面板；110′阵列基板；120′彩膜基板；130′液晶；200′背光源模块；400′双面胶带；W′双面胶带的宽度；20、30、40、50液晶显示模块；100液晶显示面板；110阵列基板；120彩膜基板；200背光源模块；300粘合剂；T粘合剂的厚度；400双面胶带；W双面胶带的宽度。
根据本公开，液晶显示模块包括液晶显示面板和背光源模块，其中液晶显示面板和背光源模块的至少一个侧边在外表面利用粘合剂固定。以下结合第一、第二、第三和第四实施例描述根据本公开的液晶显示模块。
图2a、2b、2c、2d示出第一实施例的液晶显示模块20。图2a为液晶显示模块20的俯视图，图2b为沿A-A′线(平行于一对侧边)截取的剖面图，图2c为沿B-B′线(平行于另一对侧边)截取的剖面图，并且图2d为图2c中虚线框部分的局部放大图。
如图2b、2c所示，液晶显示模块20包括背光源模块200和布置在背光源模块200上的液晶显示模板100。液晶显示模板100可以包括阵列基板110、彩膜基板120以及布置在二者之间的液晶(未示出)。
如图2a所示，在第一实施例中，液晶显示模块20采用粘合剂300，该粘合剂300应用在液晶显示模板100和背光源模块200的仅仅一个侧边(例如，左侧边)的外表面上。
如图2d的局部放大图所示，粘合剂300具有0.05-0.5mm的厚度T。粘合剂300的厚度T是截面形状的最高点到液晶显示面板100和背光源模块200的相应侧边的外表面的距离。图2c、2d所示的粘合剂300 具有拱形截面形状。然而这仅仅是示意性的。粘合剂300还可以具有诸如梯形、截顶拱形等截面形状。
在此实施例中，仅仅在左侧边的外表面上应用了粘合剂300。这种情况下，当粘合剂300具有合适的厚度T时，例如当厚度T为0.1mm时，粘合剂300就可以提供足够的粘合强度，将液晶显示面板100和背光源模块200牢固地粘合。
实践中，粘合剂300的厚度T可以根据具体设计需求确定。一方面，为了使液晶显示模块20具有窄边框，可以将粘合剂300的厚度T控制在0.05-0.1mm的范围，从而有效地减小液晶显示模块20的边框宽度。这种情况下，假设液晶显示模块20的非显示区域的宽度为0.5mm，则液晶显示模块20的边框宽度为0.55-0.6mm。由此可见，液晶显示模块20在左侧边的边框宽度仅为0.55-0.6mm，显著低于采用双面胶带时的边框宽度下限0.8mm。也就是说，通过在侧边的外表面应用粘合剂300，可以减小液晶显示模块20在该侧边的边框宽度。另一方面，可以使粘合剂300具有较大的较厚T，例如0.1-0.5mm，从而进一步增大液晶显示模板100和背光源模块200之间的粘合强度。
粘合剂300可以为UV固化粘合剂、热固性粘合剂或热塑性粘合剂。因此，可以采用本领域中常用的任何UV固化粘合剂、热固性粘合剂或热塑性粘合剂，将液晶显示面板100和背光源模块200粘合固定。
粘合剂300可以为黑色粘合剂。黑色粘合剂300不透光，因此可以防止液晶显示模块20的漏光现象。当然，粘合剂300也可以是其它颜色。
图3a、3b、3c示出第二实施例的液晶显示模块30。图3a为液晶显示模块30的俯视图，图3b为沿图3a的A-A′线截取的剖面图，以及图3c为沿图3a的B-B′线截取的剖面图。
与第一实施例的液晶显示模块20不同之处在于，在第二实施例的液晶显示模块30中，粘合剂300应用在液晶显示模板100和背光源模块200的两个侧边的外表面上。如图3a、3c所示，粘合剂300应用在液晶显示模板100和背光源模块200的左、右侧边的外表面上。在本实施例中，粘合剂300应用在液晶显示模板100和背光源模块200的相对的一对侧边的外表面上。当然，粘合剂300也可以应用在液晶显 示模板100和背光源模块200的相邻的一对侧边的外表面上。
第二实施例的液晶显示模块30的其余方面与第一实施例的液晶显示模块20相似，在此不再赘述。
图4a、4b、4c示出第三实施例的液晶显示模块40。图4a为液晶显示模块40的俯视图，图4b为沿图4a的A-A′线截取的剖面图，以及图4c为沿图4a的B-B′线截取的剖面图。
与第一和第二实施例的液晶显示模块20、30不同之处在于，在第三实施例的液晶显示模块40中，粘合剂300应用在液晶显示模板100和背光源模块200的三个侧边的外表面上。如图4a、4c所示，粘合剂300应用在液晶显示模板100和背光源模块200的左、上、右侧边的外表面上。
第三实施例的液晶显示模块40的其余方面与第一和第二实施例的液晶显示模块20、30相似，在此不再赘述。
应指出，在图4a、4b、4c所示第三实施例的基础上，液晶显示模块还可以包括应用在液晶显示模板100和背光源模块200的下侧边的外表面上的粘合剂300。也就是说，液晶显示模块可以包括被应用在液晶显示面板和背光源模块的四个侧边的外表面上的粘合剂。
因此，可以根据液晶显示模块的设计需要，在液晶显示面板和背光源模块的相应侧边应用胶合剂，从而实现液晶显示面板和背光源模块之间的牢固粘合。此外，通过控制胶合剂的厚度，可以减小液晶显示模块在相应侧边的边框宽度。
应指出，在本公开的液晶显示模块中，也可以使用双面胶带，将其应用在液晶显示面板和背光源模块的未应用粘合剂的侧边。具体而言，在液晶显示面板和背光源模块的未应用粘合剂的侧边，双面胶带可以被应用在液晶显示面板和背光源模块之间。
例如，在图2a中，双面胶带可以应用在液晶显示模块20的上、下、右侧边中的一个或多个。在图3a中，双面胶带可以应用在液晶显示模块30的上、下侧边中的一个或多个。在图4a中，双面胶带可以应用在液晶显示模块40的下侧边。通过粘合剂和双面胶带相结合，可以进一步提高液晶显示面板100和背光源模块200之间的粘合强度。
图5a、5b、5c、5d示出第四实施例的液晶显示模块50。图5a为液晶显示模块50的俯视图，图5b为沿图5a的A-A′线截取的剖面图， 图5c为沿图5a的B-B′线截取的剖面图，以及图5d为图5b中虚线框部分的局部放大图。
液晶显示模块50包括背光源模块200和布置在背光源模块200上的液晶显示模板100。液晶显示模板100可以包括阵列基板110和彩膜基板120。如图5a所示，在第四实施例的液晶显示模块50中，粘合剂300应用在液晶显示模板100和背光源模块200的相对的一对侧边(即，左、右侧边)的外表面上。
如图5a、5b的下侧边所示，在平行于A-A线的方向上，阵列基板110的宽度大于彩膜基板120的宽度。即，阵列基板110在下侧边延伸超出彩膜基板120。通常，在该下侧边，阵列基板110比彩膜基板120宽的***区域可以充当例如FPC连接区域或者驱动IC绑定区域。由于FPC或驱动IC芯片通常不透光，液晶显示模块50在下侧边的边框宽度对FPC连接区域或者驱动IC绑定区域比较敏感，而对是否使用双面胶带以及双面胶带的宽度不敏感。因此，如图5b、5d所示，在下侧边，在阵列基板110和背光源模块200之间应用双面胶带400，从而进一步提高粘合强度。双面胶带400具有宽度W，该宽度没有特殊限制。
优选地，双面胶带400还可以在上侧边应用在阵列基板110和背光源模块200之间，如图5b的顶部所示。这种情况下，上侧边的双面胶带400通常具有较小宽度，例如0.8mm，从而避免上侧边的边框宽度太大。与此相比，如上所描述，在下侧边的双面胶带400的宽度W可以较大。
应指出，图5a、5b、5c仅仅示意性示出FPC连接区域或者驱动IC绑定区域的例子。例如，FPC连接区域或者驱动IC绑定区域还可以设置在液晶显示模块50的相邻两个侧边。
本公开还提供了一种显示装置，其包括上文所描述的液晶显示模块20、30、40、50中的任意一种。
该显示装置可以为任何具有显示功能的产品或部件，诸如手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等。对于该显示装置的其它必不可少的组成部分均为本领域普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。该显示装置的实施例可以参见上述液晶显示模块20、30、40、50的实施例，在此不再赘述。
本公开还提供了一种液晶显示模块的制作方法。如图6的流程图所示，该方法包括：步骤S10、在待粘合的液晶显示面板和背光源模块的至少一个侧边的外表面应用粘合剂；以及步骤S20、固化粘合剂，从而固定液晶显示面板和背光源模块以形成液晶显示模块。
在该方法的一实施例中，在步骤S10之前，该方法还可以包括：步骤S110、在液晶显示面板和背光源模块的将不应用粘合剂的侧边，在液晶显示面板和背光源模块之间应用双面胶带。
在该方法的一实施例中，该液晶显示面板可以包括阵列基板和彩膜基板，并且步骤S110可以包括：在液晶显示面板的阵列基板和背光源模块之间应用双面胶带。
在该方法的一实施例中，步骤S110可以包括：在阵列基板的延伸超出彩膜基板的侧边，在阵列基板和背光源模块之间应用双面胶带。
在该方法的一实施例中，粘合剂可以为UV固化粘合剂、热固性粘合剂或热塑性粘合剂。
在该方法的一实施例中，优选地，粘合剂可以为黑色的。
在该方法的一实施例中，优选地，在固化之后粘合剂的厚度可以为0.05-0.5mm。
应指出，可以采用常规方法和设备来执行上述方法的各个步骤或动作，例如粘合剂的应用、固化，双面胶的应用等。为了清楚起见，本公开省略对这些常规方法和设备的描述。
根据本公开，在液晶显示模块中，液晶显示面板和背光源模块的至少一个侧边在外表面应用粘合剂，从而实现二者之间的牢固粘合。由于在侧边的外表面利用胶合剂粘合固定液晶显示面板和背光源模块，因此不需要采用双面胶带粘合。即，本公开提供了一种替代双面胶带的方案，该方案可以实现液晶显示面板和背光源模块之间的牢固粘合。附加地，根据本公开，由于不使用双面胶带，液晶显示模块的边框宽度不再受限于双面胶带的宽度，并且通过控制胶合剂的厚度可以减小液晶显示模块的边框宽度。
仅仅是出于图示和说明的目的而给出对本公开实施例的前述描述。它们不是旨在穷举或者限制本公开内容。因此，本领域技术人员将容易想到许多调整和变型。具体而言，本公开的范围将由所附权利要求定义。
