本申请提出一种液晶显示设备。
参照图1和图2，在本申请一实施例中，该液晶显示设备包括：
壳体，所述壳体包括背板10，所述背板10包括板本体11，以及分设于所述板本体11相对两侧边的两侧板体12，两所述侧板体12的内侧面上各设有对应侧边延伸的侧隔板13，所述板本体11、两所述侧板体12及两所述侧隔板13共同限制出相对的两所述滑槽16；
光学模片组20，滑动安装至两所述滑槽16；以及，
显示屏30，与所述光学模片组20相对设置，并固设在所述侧隔板13的前侧面。
不失一般性，本实施例中，光学模片组20包括反射片21、导光板22及其他光学膜片（例如DOP膜片23）；显示屏30则通常采用LCD屏。
本实施例中，板本体11、两侧板体12和侧隔板13是一体成型的，以利于壳体的批量生产。另外，本实施例中，侧隔板13设置为一沿对应侧边延伸的整体板状件，可以理解，显示屏30和光学模片组20是分设于侧隔板13的前后两侧；当然，于其他实施例中，侧隔板13也可包括在对应侧边的延伸方向上间断设置的多个板状件，如此，亦能实现其隔设作用。
需要说明的是，本申请的技术方案中，光学模片组20与滑槽16之间可以是适配的滑动装配，即光学模片组20与滑槽16之间的滑动是不具有间隙的；也可以是间隙的滑动装配，即光学模片组20与滑槽16之间的滑动是可具有间隙的。
可以理解，侧隔板13的设置可为显示屏30和光学模片组20在支撑框上的装配提供依附和支撑。具体地，参照图6、图8和图9，在装配显示屏30和光学模片组20时，先将光学模片组20的反射片21从前往后装入板本体11的内侧面，再将光学模片组的剩余其它模片（如导光板22和DOP膜片23）滑动安装至两滑槽16内，即可使光学模片组安装至壳体上；然后将显示屏30从正面直接放置在侧隔板13的前侧，并将显示屏30与侧隔板13进行固定。本实施例中，显示屏30和光学模片组20可固定于侧隔板13或侧板体12上，具体地，显示屏30可粘接固定于侧隔板13，且粘接所采用的材料可以是黏性胶，也可以是双面胶，本申请对此不作限制。
本申请中，通过在背板10上设置侧隔板13，该侧隔板13与背板10的板本体11之间形成供光学模片组滑动安装的滑槽16，而侧隔板13代替胶框用以支撑显示屏30，由于无需额外设置胶框用于支撑显示屏30，有利于实现壳体的超薄超窄边框设计。
请再次参考图2，本实施例中，所述侧隔板13的后侧面设有限位凸部131，所述限位凸部131抵压在所述光学模片组上。于本实施例中，限位凸部131可由侧隔板13的后侧面增加表面材料的形式形成；当然，于其他实施例中，限位凸部131可由侧隔板13的前侧面部分朝后凹陷，而在侧隔板13的后侧面且对应凹陷的位置所形成。限位凸部131优选沿侧隔板13延伸形成一长条状，以对光学模片组进行更好的抵接限位，防止光学模片组下滑。当然，于其他实施例中，限位凸部131可包括在对应侧隔板13的延伸方向上间断设置的多个凸起，如此，亦能实现其限位作用。
请参照图3，在本实施例中，进一步地，所述背板10还包括设于所述板本体11顶边的顶板体14，且所述板本体11的底边空置，以在两所述滑槽16的下端之间形成供所述光学模片组滑入安装的安装口。所述光学模片组自所述安装口滑入所述壳体，至所述光学模片组的顶部抵止于所述顶板体14。本实施例中，顶板体14是属于背板10的一部分，并与背板10一体成型，以利于壳体的批量生产，并有利于减少螺钉等连接件的设置，实现壳体的超薄超窄边框设计。不失一般性，在壳体上，通常地，顶板体14的两端分别与两侧板的顶端连接。可以理解，本实施例中，光学模片组的整体滑动装配方向是自背板10的底边朝向顶边的方向，顶板体14的设置，可避免光学模片组在整体滑动装配过程中，出现滑出背板10顶边的现象。然本设计不限于此，于其他实施例中，壳体的安装口也可形成在壳体的顶端，而使得显示模组的整体滑动装配方向是自背板10的顶边朝向底边的方向；例如但不限于，背板10的底边和顶边均空置，以在两滑槽16的下端之间形成安装口、及在两滑槽16的上端之间形成装饰口，此时，光学模片组可自安装口和装饰口中的任一者滑入壳体。
本实施例中，所述顶板体14的内侧面设有顶隔板15，所述顶隔板15与所述板本体11相对，所述顶隔板15、所述板本体11以及所述顶板体14共同限制出沿所述顶板体14的长度方向延伸的限位槽，所述光学模片组的顶部抵止于所述限位槽的槽底，如此，一方面可以通过顶隔板15辅助增大防止光学模片组脱离壳体的限制力，另一方面可以保持壳体前侧的顶部和两侧部的外观一致性。类似地，顶隔板15同样为背板10的一部分，并与顶板体14一体成型。
所述顶隔板15的后侧面同样设有限位凸部131，所述限位凸部131抵压在所述光学模片组上。于本实施例中，限位凸部131可由顶隔板15的后侧面增加表面材料的形式形成；当然，于其他实施例中，限位凸部131可由顶隔板15的前侧面部分朝后凹陷，而在顶隔板15的后侧面且对应凹陷的位置所形成。
进一步地，在所述限位槽的槽底还设有缓冲垫60，所述光学模片组的顶部抵止于所述缓冲垫60。由于光学模片组在工作过程中，由于受热会产生膨胀形变，故通过在光学模片组的顶部设置缓冲垫60，光学模片组膨胀时挤压缓冲垫60，缓冲垫60则为光学模片组提供变形的缓冲空间，以避免光学模片组直接接触顶板体14，而被挤压损毁。
本实施例中，所述侧板体12的前侧凸出所述侧隔板13设置，以在所述显示屏30的两侧形成挡边，从而避免显示屏30的两侧缘显露在外，同时也可对显示屏30进行限位，避免显示屏30沿两侧移动。同样地，所述顶板体14的前侧凸出所述顶隔板15设置，以在所述显示屏30的顶部形成挡边。当然，于其它实施例中，侧板体12的前侧可与侧隔板13平齐，顶板体14的前侧也可与顶隔板15平齐。
本实施例中，所述背板10为钣金件，所述侧隔板13由所述侧板体12的前侧弯折形成；同样地，所述顶隔板15由所述顶板体14的前侧弯折形成，如此有利于加工成型。
本申请中的液晶显示设备可为直下式，也可为侧入式。例如，在本实施例中，液晶显示设备为直下式，则所述板本体朝后拱起，以在所述板本体的内侧面形成供所述液晶显示设备的光源安装的安装腔。
参照图1、图4和图5，进一步地，液晶显示设备还包括封闭所述安装口的封口组件，所述封口组件与所述背板10固定，以将光学模片组限制在壳体内。需要说明的是，在背板10的底边和顶边均空置的技术方案中，为避免光学模片组自上下两端的安装口显露于外，而影响液晶显示设备的外观，可选地，液晶显示设备的上下两端的安装口处均设有封口组件，两封口组件对应封闭上下两端的所述安装口。该封口组件可以是装饰薄膜件，也可以是顶装饰框条50，只要能实现安装口的封闭即可。
本实施例中，所述封口组件包括定位件40，所述定位件40包括定位基板41，以及分设于所述定位基板41两侧的定位侧板42和安装板43，所述定位基板41位于所述光学模片组的底部，并沿所述光学模片组的底部延伸，所述定位侧板42位于所述光学模片组的前侧面，且所述定位侧板42的后侧面设有后定位凸部421，所述光学模片组的下端对应设有供所述后定位凸部421插合的定位孔24；所述安装板43位于所述光学模片组的后侧面，并与所述板本体11固定。于本实施例中，安装板43优选通过螺钉与板本体11进行固定；当然，其它实施例中，安装板43也可与板本体11卡接或焊接等。本实施例中，后定位凸部421可包括在对应定位侧板42的延伸方向上间断设置的多个凸起；当然，其它实施例中，后定位凸部421可沿定位侧板42的延伸方向形成一长条状，以对光学模片组进行更好的抵接限位，防止光学模片组下滑。本实施例中，定位侧板42上设有通孔，通孔的孔壁上设有一定位板，定位板与定位侧板42是一体成型的，通过将定位板朝后压而形成前定位凸部423。
本实施例中，由于安装板43和定位侧板42是分设于定位基板41的前后两侧的，则相当于安装板43与定位侧板42，以及定位基板41之间形成开口朝内的凹槽，光学模片组的下端伸入凹槽内。同时，由于在定位侧板42的后侧面设有后定位凸部421，后定位凸部421朝上抵顶光学模片组，从而避免了光学模片组朝下滑出滑槽16。
进一步地，所述定位侧板42的后侧面设有抵压凸部422，所述抵压凸部422抵压于所述光学模片组20的前侧面，以对光学模片组的下端进行限位，从而防止光学模片组下端朝前翘起。
进一步地，所述定位侧板42的前侧面还设有前定位凸部423，所述显示屏30的底部与所述前定位凸部423抵顶。本实施例中，前定位凸部423可包括在对应定位侧板42的延伸方向上间断设置的多个凸起；当然，其它实施例中，前定位凸部423可沿定位侧板42的延伸方向形成一长条状，以对显示屏30进行更好的抵接限位，防止显示屏30下滑。本实施例中，定位件40为钣金件，定位侧板42上设有通孔，通孔的孔壁上设有一定位板，定位板与定位侧板42是一体成型的，通过将定位板朝前压折弯而形成前定位凸部423。
安装板43是与板本体11的内侧面贴合设置的，以减小壳体厚度。板本体11的内侧面，且在靠近下端的位置朝后凹陷，而在板本体11的内侧面形成供安装板43贴合设置的让位空间，避免安装板43与光学模片组发生干涉。
本申请中，当液晶显示设备为侧入式时，其光源可设置在封口组件与导光板22的底边之间，光源的正面朝向导光板22的底边，以使其所发出的背光光线进入导光板22；光源的背面则贴合于封口组件，以通过封口组件进行散热。于其他实施例中，光源则可设置在顶板体14的内侧面，以使其所发出的背光光线从导光板22的顶边入射，可以理解，此情况下，为光源进行供电的供电导线需延伸至壳体的顶部。需要说明的是，光源设置在导光板22底部的方案中，光源是位于定位基板41与导光板22底边之间的，且光源与定位基板41固定。定位基板41优选采用金属件制成，以对光源进行散热，从而获得较高的散热效率。
进一步地，所述封口组件还包括位于所述定位件40外侧的装饰框条50，所述装饰框条50包括装饰底板51、及设于所述装饰底板51前侧的装饰侧板52。所述装饰底板51与所述定位基板41固定，以间接固定于背板10。本实施例中，装饰底板51优选与定位基板41的底面贴合固定，以减小壳体的整体厚度。于本实施例中，装饰底板51通过螺钉与定位基板41固定；当然，于其它实施例中，装饰底板51则与定位基板41焊接或者卡接。所述装饰底板51的后侧至少包覆至所述板本体11的底边，以避免显示屏30底边与装饰底板51之间的部件，以及避免光学模片组底边与装饰底板51之间的部件显露于外。本实施例中，由于显示屏30较重，为避免显示屏30在重力的作用下下滑，在装饰底板51与显示屏30底边之间还增设有与背光灯条并排设置的屏支撑条。
本实施例中，所述装饰侧板52与所述定位侧板42相间隔设置，所述显示屏30的底部位于所述装饰侧板52与所述定位侧板42之间。为更好对显示屏30进行限位，所述装饰侧板52的内侧面设有止挡凸部53，所述止挡凸部53与所述显示屏30的前侧面抵接，从而避免了当显示屏30与侧隔板13粘接不牢时朝前翘起。同时，通过设置止挡凸部53也能够保证装饰侧板52与显示屏30密封抵接，防止灰尘进入。本实施例中，止挡凸部53呈长条状，优选沿着装饰侧板52的延伸方向延伸。于其它实施例中，止挡凸部53可包括多个沿着装饰侧板52的延伸方向间隔设置的限位凸点。止挡凸部53与装饰侧板52为分体设置，例如，止挡凸部53嵌设在装饰侧板52的后侧面上；或者，止挡凸部53卡接在装饰侧板52的后侧面上；当然，止挡凸部53可与装饰侧板52一体成型。
请结合参考图6至图9，在装配时，先将光学模片组20的反射片21从前往后装入板本体11的内侧面，再将缓冲垫60朝顶板体14的方向推到与顶板体14抵顶，接着将光学模片组20的剩余其它模片（如导光板22和DOP膜片23）滑动安装至两滑槽16内，即可使光学模片组安装至壳体上；然后将显示屏30从正面直接放置在侧隔板13的前侧，并将显示屏30与侧隔板13进行固定。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
