本发明实施例提供一种模块化液晶显示装置,其包括第一液晶显示面板、第二液晶显示面板、设置在所述第一液晶显示面板和所述第二液晶显示面板上部的光源模块以及设置在所述第一液晶显示面板和所述第二液晶显示面板侧部的两个侧面封装结构件;所述第一液晶显示面板和所述第二液晶显示面板的下部相互连接;所述第一液晶显示面板、所述第二液晶显示面板、所述光源模块以及两个所述侧面封装结构件构成一封闭的容纳空间;

相较于现有的模块化液晶显示装置,本发明的模块化液晶显示装置通过容纳空间结构的设计,简化了模块化液晶显示装置的结构,加强了模块化液晶显示装置的散热效果,且由于提高了光源的利用率,因此降低了模块化液晶显示装置的能耗;解决了现有的模块化液晶显示装置的整体体积较大、能耗以及散热效果较差的技术问题。
为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:
附图说明
图1是一种现有的模块化液晶显示装置的结构示意图;
图2为本发明的模块化液晶显示装置的第一优选实施例的结构示意图;
图3为沿图2的A-A’截面线的截面图;
图4为本发明的模块化液晶显示装置的第一优选实施例的光源放置板上的LED光源的排列示意图;
图5为本发明的模块化液晶显示装置的第二优选实施例的结构示意图;
图6为本发明的模块化液晶显示装置的第三优选实施例的结构示意图。
具体实施方式
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。
在图中,结构相似的单元是以相同标号表示。
请参照图2至图4,图2为本发明的模块化液晶显示装置的第一优选实施例的结构示意图;图3为沿图2的A-A’截面线的截面图;图4为本发明的模块化液晶显示装置的第一优选实施例的光源放置板上的LED光源的排列示意图。
本优选实施例的模块化液晶显示装置20包括第一液晶显示面板21、第二液晶显示面板22、光源模块23以及两个侧面封装结构件24。光源模块23设置在第一液晶显示面板21和第二液晶显示面板22上部,侧面封装结构件24设置在第一液晶显示面板21和第二液晶显示面板22的侧部,第一液晶显示面板21和第二液晶显示面板22的下部相互连接,第一液晶显示面板21、第二液晶显示面板22、光源模块23以及两个侧面封装结构件24构成一封闭的容纳空间。其中第一液晶显示面板21的所在平面和第二液晶显示面板22的所在平面的夹角小于等于120度。
优选的,第一液晶显示面板21朝向容纳空间的一侧设置有第一光学膜片组25,第二液晶显示面板22朝向容纳空间的一侧设置有第二光学膜片组26。
如图3所示,光源模块23包括LED光源231、反射片232以及散热器233。其中LED光源231通过光源放置板设置在容纳空间内侧,反射板232设置在相邻LED光源231之间,用于对LED光源231的出射光进行反射操作,散热器233设置在容纳空间外侧。同时侧面封装结构件24的内侧也设置有反射片(图中未示出),这样LED光源231出射的光线只能通过第一液晶显示面板21和第二液晶显示面板22出射,且LED光源231产生的热量可以通过散热器233较好的导出。
如图4所示,光源放置板上放置距离值较小的区域的LED光源231的数量密度大于放置距离值较大的区域的LED光源231的数量密度,其中区域的放置距离值为该区域与第一液晶显示面板21的距离,与该区域与第二液晶显示面板22的距离的差值绝对值。
由于第一液晶显示面板21和第二液晶显示面板22的各个区域与光源放置板的距离不一致,因此这里根据具体光源放置板和液晶显示面板之间的距离,设置LED光源231的数量密度,即光源放置板上与相应的液晶显示面板的距离越大的区域,设置的LED光源231的数量密度也越大。这样可以较好的保证第一液晶显示面板21和第二液晶显示面板22的显示亮度均一性。
本优选实施例的模块化液晶显示装置20使用时,光源模块23的LED光源231发出的光线可通过容纳空间直接入射到第一液晶显示面板21和第二液晶显示面板22上,部分没有直接入射到第一液晶显示面板21和第二液晶显示面板22上的入射光,通过容纳空间中的反射片232再次反射到容纳空间中,最终也从第一液晶显示面板21和第二液晶显示面板22上出射。因此有效的降低了模块化液晶显示装置20的能耗;同时光源模块23的散热器233可有效的对LED光源231进行散热处理,因此可在保证光源利用率的基础上,通过容纳空间提升模块化液晶显示装置20的散热效果,从而降低模块化液晶显示装置20的能耗。
在视觉方面,第一液晶显示面板21的所在平面和第二液晶显示面板22的所在平面之间形成一小于120度的夹角,从而第一液晶显示面板21和第二液晶显示面板22均向下倾斜显示,使得在模块化液晶显示装置20下行走的用户具有较好的视觉可视范围。
因此本优选实施例的模块化液晶显示装置通过容纳空间结构的设计,简化了模块化液晶显示装置的结构,加强了模块化液晶显示装置的散热效果,且由于提高了光源的利用率,因此降低了模块化液晶显示装置的能耗。
请参照图5,图5为本发明的模块化液晶显示装置的第二优选实施例的结构示意图。本优选实施例的模块化液晶显示装置30包括第一液晶显示面板31、第二液晶显示面板32、光源模块33以及两个侧面封装结构件34。
光源模块33包括LED光源331、反射片332、散热器333以及突出件334。
在第一优选实施例的基础上,本优选实施例的模块化液晶显示装置30的光源模块33的LED光源331通过一突出件334设置在容纳空间内侧,反射片332设置在突出件334的外部两侧。由于突出件334设置在容纳空间的中部,这样可较好的改善LED光源331与相应的液晶显示面板之间的距离,且由于减少了光线反射后的间接射出,因此进一步提高了LED光源331的光源利用率。
如该突出件334设置的高度合适,LED光源331可均匀的设置在突出件334的外表面,从而简化LED光源331的设置方式。
本优选实施例的模块化液晶显示装置30的具体工作原理与上述模块化液晶显示装置20的第一优选实施例中描述的相同或相似,具体请参见上述模块化液晶显示装置20的第一优选实施例中的相关描述。
在第一优选实施例的基础上,本优选实施例的模块化液晶显示装置通过突出件的设置进一步提高了LED光源的光源利用率,且简化了LED光源的设置方式。
请参照图6,图6为本发明的模块化液晶显示装置的第三优选实施例的结构示意图。本优选实施例的模块化液晶显示装置40包括第一液晶显示面板41、第二液晶显示面板42、光源模块43以及两个侧面封装结构件44。
光源模块43包括LED光源431、反射片432、散热器433以及散热突出件434。
在第一优选实施例的基础上,本优选实施例的模块化液晶显示装置40的光源模块43的LED光源431通过一散热突出件434设置在容纳空间内侧,反射片432设置在散热突出件434的外部两侧,该散热突出件434与散热器433连接。由于散热突出件434设置在容纳空间的中部,这样可较好的改善LED光源431与相应的液晶显示面板之间的距离,且由于减少了光线反射后的间接射出,因此进一步提高了LED光源431的光源利用率。
如该散热突出件434设置的高度合适,LED光源431可均匀的设置在散热突出件434的外表面,从而简化LED光源431的设置方式。
同时由于散热突出件434的设置,可相应的减小散热器433的体积,从而减小模块化液晶显示装置40的整体体积。
本优选实施例的模块化液晶显示装置40的具体工作原理与上述模块化液晶显示装置20的第一优选实施例中描述的相同或相似,具体请参见上述模块化液晶显示装置20的第一优选实施例中的相关描述。
在第一优选实施例的基础上,本优选实施例的模块化液晶显示装置通过散热突出件的设置进一步提高了LED光源的光源利用率,且进一步减小了模块化液晶显示装置的整体体积。
本发明的模块化液晶显示装置通过容纳空间结构的设计,简化了模块化液晶显示装置的结构,加强了模块化液晶显示装置的散热效果,且由于提高了光源的利用率,因此降低了模块化液晶显示装置的能耗;解决了现有的模块化液晶显示装置的整体体积较大、能耗以及散热效果较差的技术问题。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
