 本发明的最佳实施方式
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。
请参阅图2，图2为本发明提供的背光模组的较佳实施例的爆炸结构示意图。所述背光模组包括背板21、导光板22以及光源23。
所述导光板22包括有入光面、底面（图未标示）以及出光面221，所述光源23设置于所述导光板22的入光面，所述导光板22的底面贴合连接所述背板21。
所述背板21为一金属板，所述背板21包括有内侧面和外侧面（图未标示），所述背板21的内侧面为平面状，贴合连接所述导光板22的底面。
请一并参阅图3，所述背板21的内侧面设置一反射层211，所述反射层211与所述背板21一体成型。优选的，所述反射层211由所述背板21的内侧面涂布反光材料形成。所述反光材料优选采用白色反光材料，该白色反光材料譬如含有二氧化钛粉末或者硫酸钡粉末的涂料，当然也可以是其它的反光材料，只要能够涂布于所述背板21的内侧面形成反射层211，并对射向所述背板21内侧面的光线进行反射即可，此处不一一列举。值得注意的是，本发明所指的“一体成型”并非指所述背板21与所述反射层211由同一材质制成，而是指所述反射层211完全直接预形成在所述背板21的内侧面上。
本发明中，所述反射层211通过涂布方式形成于所述背板21的内侧面，譬如通过喷嘴涂布形成。当然也可以由其它的方式形成，此处不一一列举。
请一并参阅图4，所述背板21的外侧面背对于所述内侧面，所述背板21的外侧面设置有固定件212，所述固定件212相对所述背板21的外侧面向外凸起(即朝向远离内侧面的方向凸起)。所述固定件可与所述背板21一体成型，由所述背板21的外侧面凸伸形成，也可通过其它方式固定连接至所述背板21的外侧面而形成。
更优的，所述固定件212为铆钉，所述铆钉以铆接的方式固定连接所述背板21的外侧面，当然也可以是其它的固定件，只要能够相对所述背板21的外侧面凸起，并能够通过固定结构212实现背光模组与整机完成装配即可，此处不一一列举。
本发明通过在背板21的外侧面设置固定件212，并通过所述固定件212将所述背板21装配至整机上，相较于通过冲压方式形成凸包的技术而言，本发明的固定件方式可节省费用，进而降低了显示面板的生产成本。
本发明提供的背光模组的工作原理描述如下：
请一并参阅图2，从所述光源23出射的光线由所述导光板22的入光面进入导光板22，进入所述导光板的光线射向所述导光板22的底面，射向所述导光板22底面的光线进一步的射向所述背板21的内侧面。上述导光板22的入光面一般是指所述导光板22的侧面，此时所述光源23设于所述导光板22的侧面的外侧；但所述入光面也可能是指所述导光板22的底面，此时所述光源23设于所述导光板22的底面与所述背板21之间。
由于所述背板21的内侧面形成有所述反射层211，因此射向所述背板21的内侧面的光线经所述反射层211反射后返回所述导光板22，并最终从所述导光板22的出光面221出射。
显然，本发明通过在所述背板21的内侧面设置一反射层211，该反射层211与所述背板21一体成型设计，譬如通过在背板21的内侧面上涂布白色反光材料形成所述反射层211。通过该方式，实现了将光学反射结构与背板21有机结合为一体的目的。由于所述反射层211与所述背板21一体成型，因此不会产生变形等问题，因而保证了反射效果，进而提高了所述背光模组的光学效果。而且相较于现有技术省去了反射片，因此极大的节省了成本。而且由于设置在所述背板21外侧面的固定件212可提高所述背光模组的装配效率，因此进一步的节省了成本。
本发明还提供一种显示面板，所述显示面板包括本发明提供的背光模组，其中所述背光模组包括背板21、导光板22以及光源23，所述背板21的内侧面形成有用于反射光线的反射层211，其中所述反射层211与所述背板21一体成型，譬如通过在所述背板21的内侧面涂布白色反光材料形成所述反射层211，该反射层211用于对射向所述背板21内侧面的光线进行反射。鉴于该背光模组在上文已有详细的描述，此处不再赘述。
本发明通过将背板的内侧面设计为平面状，并涂布反光材料形成反射层，从导光板的入光面进入导光板的光线射向背板的内侧面，经背板的内侧面上的反射层反射后，返回导光板并从导光板的出光面出射。显然，本发明可以解决现有技术中由于反射片容易受到外部影响产生变形，进而影响对光线的反射效果，导致显示器显示效果不佳的技术问题，保证了显示器的显示效果。
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。
