Description

一种背光模组和显示面板
本申请要求于2018年10月30日提交中国专利局、申请号为CN201821774482.6、申请名称为“一种背光模组和显示面板”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种背光模组和显示面板。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
随着科技的发展和进步，平板显示器由于具备机身薄、省电和辐射低等热点而成为显示器的主流产品，得到了广泛应用。平板显示器包括薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)和机发光二极管(Organic Light-Emitting Diode，OLED)显示器等。其中，薄膜晶体管液晶显示器通过控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面，具有机身薄、省电、无辐射等众多优点。而机发光二极管显示器是利用有机电致发光二极管制成，具有自发光、响应时间短、清晰度与对比度高、可实现柔性显示与大面积全色显示等诸多优点。
在液晶显示屏行业中，我们对于光学部材反光层(Reflector)、导光板(light guide plate，LGP)和光学薄板在组装过程中，目前有耳挂防呆、倒C角防呆以及在胶框上开槽防呆；但是这种背光结构往往实现的防呆的方向单一。

如图1至图7所示，实施例进一步详细描述本申请的背光模组和显示面板。
一种背光模组，包括背板110和光学部件120，光学部件120固定于背板110上；光学部件120上设有防呆结构241，防呆结构241包括凸起330，凸起330位于光学部件120与背板110配合固定的表面；背板110上设有与防呆结构241配合固定的定位结构242。
本方案中，考虑到背光模组100的固定是将光学部件120固定到背板110上，而光学部件120的反、正面看起来较相似，所以安装时经常会有装反的现象，这样会使工作效率降低，因此，本方案通过在光学部件120与背板110配合固定的表面设有包括凸起330的防呆结构241，因为安装后的光学部件120与背板110贴合，这样防呆结构241会随着安装固定后而隐藏其中，不会出现占额外的空间，而且包括凸起330的防呆结构241很明显在光学部件120的一侧，安装工作人员可以一眼清楚区别安装正、反面，同时在背板110上设有与防呆结构241配合固定的定位结构242，防呆结构241与定位结构242对应配合固定，这样防呆结构241还可以实现光学部件120安装方向的对齐放置，从而起到了定位作用，极大提升了背光 模组100的安装效率。
在一实施例中，其它扫描线段112的包括：与主动开关113相连并和交汇扫描线段210相连的扫描线段为第一扫描线段220；与第一扫描线段220相连并且线宽大于交汇扫描线段210的扫描线段为第二扫描线段230；与交汇扫描线段210相连并且非第一扫描线段220的扫描线段为第三扫描线段240；与第三扫描线段240相连并且线宽大于交汇扫描线段210的扫描线段为第四扫描线段250。
光学部件120包括反射片、导光板、偏光片以及光学膜片121等。以下实施方式如无特殊说明，均以光学膜片121为例进行说明。
在一实施例中，凸起330的高度小于或等于背板110的厚度。
本方案中,考虑到光学膜片121安装到背板110上后，需要具备一定的牢固性，若防呆结构241的凸起330的高度大于背板110的厚度，那么会出现光学膜片121安装后，防呆结构241会穿过背板110而突出背板110，这样不但不美观，而且在使用中容易碰触到突出部分的防呆结构241，进而会波及到光学膜片121，严重可能损坏光学膜片121，因此，本方案设计的防呆结构241的凸起330的高度小于或等于背板110的厚度。
在一实施例中，光学膜片121包括主板230和支板240，支板240凸出于主板230的侧端，且支板240对称设置在主板230的两侧端上；防呆结构241设置在支板240上。
本方案中，考虑到光学膜片121通常为规则形状，且每个部位都具有一定的显示等功能，为了不影响光学部件120的功能，因此，本方案设计的光学膜片121包括主板230和支板240，支板240是主板230的延申片段，主板230负责起着光学膜片121的显示等功能，支板240负责起着光学膜片121的安装定位和防呆功能，将防呆结构241设置在支板240上，这样防呆结构241不会占用到主板230的功能位置，也就不会影响光学膜片121的正常使用，而且支板240与防呆结构241制造简单，性价比高；根据两点确定一条直线的原理，光学膜片121安装到背板110上时，防呆结构241需要对安装起到唯一性，且安装后，防呆结构241对光学膜片121起的定位功能应该满足均匀性，因此，本方案将防呆结构241的载体支板240设计在主板230的两侧，且位置关于主板230对称，这样，既可以满足防呆作用的唯一性，还可以使其对安装后的光学膜片121整体固定效果对称和均匀。
在一实施例中，防呆结构241包括第一凹陷310和第一凸台320，第一凸台320与第一凹陷310并列设置；定位结构242包括第二凸台210和第二凹陷220，第二凸台210与第二凹陷220并列设置；第一凹陷310与第二凸台210配合固定， 第一凸台320与第二凹陷220配合固定。
本方案中，设计的背板110上的定位结构242和光学膜片121的防呆结构241都包括凹陷与凸台，这样每个支板240上的防呆结构241构成类似USB型结构，对应的，在背板110上的定位结构242也构成类似USB型结构与防呆结构241对应配合，因为USB型结构不仅实现上下的防呆，还实现左右的防呆，在我们组反射片、导光板或者光学膜片的时候出现零错误的情况，不仅提高了工作效率，也极大的提高了产品的良品率。
在一实施例中，主板230包括第一端231和第二端232，第一端231对应为光学膜片121的安装始端，第二端232对应为光学膜片121的安装尾端；支板240设置在第一端231上。
本方案中，光学膜片121安装时，会先将光学膜片121的安装始端与背板110的一端对齐，然后逐渐贴合，最后将光学膜片121的尾端与背板110的另一端对齐即可完成安装，考虑到防呆结构241对光学膜片121的安装起防呆与定位作用，因此在光学膜片121安装过程中，需要从安装开始时就将防呆结构241对齐，这样会提高安装准确率与效率，因此，本方案将支板240设置在主板230的安装始端，方便光学膜片121的安装。
其中，支板240也可以设置在主板230的侧端上的从安装始端到安装尾端的任意位置，均可以起到对光学部件120与背板110之间配合的防呆作用和定位作用。
在一实施例中，防呆结构241与定位结构242配合固定后为无间隙贴合；第一凸台320和第二凸台210包括第一倒角250，第一倒角250位于第一凸台320和第二凸台210的顶端，第一倒角250的倾向由顶端倾向侧端。
本方案中，考虑到防呆结构241与定位结构242配合后，还要对光学膜片121起到限位作用，否则光学膜片121安装后不牢固，因此，通过尺寸设计，使得防呆结构241与定位结构242配合固定后为无间隙贴合，这样安装后的光学膜片121除安装方向外再无运动空间；因为无间隙配合开始时比较难安装，为了方便防呆结构241与定位结构242配合，本方案通过在第一凸台320和第二凸台210的顶端设计第一倒角250，且第一倒角250的倾向由顶端倾向侧端，这样第一倒角250会先与第一凹陷310和第二凹陷220接触，这样对第一凸台320和第二凸台210起到引导安装的作用，也可以减小安装阻力。
在一实施例中，第一凹陷310和第二凹陷220包括第二倒角260，第二倒角260位于凹陷与凸台配合的侧的开口端，且倾斜方向由外侧倾向内侧。
本方案中，考虑到防呆结构241与定位结构242配合固定后为无间隙贴合，因为无间隙配合开始时比较难安装，因此，本方案通过在第一凹陷310和第二凹陷220的开口端设计第二倒角260，且第二倒角260的倾斜方向由外侧倾向内侧，这样第二倒角260会先与第一凸台320和第二凸台210接触，这样对第一凸台320和第二凸台210起到引导安装的作用，也可以减小安装阻力。
在一实施例中，第一凸台320凸起的高度小于或等于第二凹陷220的深度。
本方案中，考虑到背板110是背光模组100的基板，对光学膜片121起支撑和一定的保护作用，因此，本方案将光学膜片121上的第一凸台320的凸起的高度小于或等于第二凹陷220的深度，这样安装时既能起到定位作用，而且安装后的第一凸台320隐藏于背板110内部，可以不受外界影响，同时也能起到定位作用，整体感更强。
在一实施例中，第二凸台210凸起的高度小于或等于第一凹陷310的深度。
本方案中，因为背板110上的定位结构242与光学膜片121上的防呆结构241都为类似USB型，那么配合后就需要考虑到，防呆与定位结构242不应影响光学膜片121的正常功能，同时因为背板110上通常会叠放安装多层光学膜片121，因此，本方案设计的第二凸台210凸起的高度小于或等于第一凹陷310的深度，这样第二凸台210就不会出现穿过光学膜片121而突出的现象，就不会影响到其它层光学膜片121的安装。
在一实施例中，在光学膜片121靠背板110侧的面的对立面上设计带有凹陷的定位结构242。
本方案中,考虑到背光模组100包括多个光学膜片121，光学膜片121之间是层叠安装，这就需要对每一个光学膜片121安装进行定位于防呆，因此，同样原理，本方案通过在光学膜片121靠背板110侧的面的对立面上设计带有凹陷的定位结构242，而将下一个具有凸起的防呆结构241的光学膜片121安装到已固定的光学膜片121上就可以实现防呆与定位。
在一实施例中，不同的光学膜片121上的凸起的防呆结构241位置不同。
本方案中,由于光学膜片121之间是层叠放置，若不同的光学膜片121上的凸起的防呆结构241位置相同，那么相对的，光学膜片121上的凹陷的定位结构242与防呆结构241位置对立重合，这样光学膜片121上的定位结构242相对脆弱，受力易损坏，而且所有光学膜片121的防呆结构241都作用在一条直线上，那么越靠近背板110的光学膜片121，其防呆结构241受损概率越大，因此，本方案设计的不同的光学膜片121上的凸起的防呆结构241位置不同。
如图1至图6所示，公开了一种背光模组100，包括背板110和光学部件120，光学部件120固定于背板110上；光学部件120上设有防呆结构241，防呆结构241包括凸起330，凸起330位于光学部件120与背板110配合固定的表面；背板110上设有与防呆结构241配合固定的定位结构242；凸起330的高度小于或等于背板110的厚度；光学部件120包括主板230和支板240；支板240凸出于主板230的侧端，且支板240对称设置在主板230的两侧端上；防呆结构241设置在支板240上；主板230包括第一端231和第二端232，第一端231对应为光学部件120的安装始端，第二端232对应为光学部件120的安装尾端，支板240设置在第一端231上；支板240对称设置在主板230的两侧端上；防呆结构241包括第一凹陷310和第一凸台320，第一凸台320与第一凹陷310并列设置；定位结构242包括第二凸台210和第二凹陷220，第二凸台210与第二凹陷220并列设置；第一凹陷310与第二凸台210配合固定，第一凸台320与第二凹陷220配合固定；第一凹陷310设计为通孔311；第一凸台320凸起的高度等于第二凹陷220的深度；第二凸台210凸起的高度等于第一凹陷310的深度；防呆结构241与定位结构242配合固定后为无间隙贴合。
本方案中，考虑到背光模组100的固定是将光学膜片121固定到背板110上，而光学膜片121反正面看起来较相似，所以安装时经常会有装反的现象，这样会使工作效率降低，因此，本方案通过在光学膜片121与背板110配合固定的表面设有防呆结构241，因为安装后的光学膜片121与背板110贴合，这样防呆结构241会随着安装固定后而隐藏其中，不会出现占额外的空间，同时在背板110上设有与防呆结构241配合固定的定位结构242，防呆结构241与定位结构242对应配合固定，这样防呆结构241可以实现光学膜片121安装方向的对齐放置，从而起到了安装方向的防呆作用，极大提升了背光模组100的安装效率；考虑到光学膜片121安装到背板110上后，需要具备一定的牢固性，若防呆结构241的凸起330的高度大于背板110的厚度，那么会出现光学膜片121安装后，防呆结构241会穿过背板110而突出背板110，这样不但不美观，而且在使用中容易碰触到突出部分的防呆结构241，进而会波及到光学膜片121，严重可能损坏光学膜片121，因此，本方案设计的防呆结构241的凸起330的高度小于或等于背板110的厚度；考虑到光学膜片121通常为规则形状，且每个部位都具有一定的显示等功能，为了不影响光学部件120的功能，因此，本方案设计的光学膜片121包括主板230和支板240，支板240是主板230的延申片段，主板230负责起着光学膜片121的显示等功能，支板240负责起着光学膜片121的安装定位和防呆功能，将防呆结构241设置在支板240上， 这样防呆结构241不会占用到主板230的功能位置，也就不会影响光学膜片121的正常使用，而且支板240与防呆结构241制造简单，性价比高；根据两点确定一条直线的原理，光学膜片121安装到背板110上时，防呆结构241需要对安装起到唯一性，且安装后，防呆结构241对光学膜片121起的定位功能应该满足均匀性，因此，本方案将防呆结构241的载体支板240设计在主板230的两侧，且位置关于主板230对称，这样，既可以满足防呆作用的唯一性，还可以使其对安装后的光学膜片121整体固定效果对称和均匀；设计的背板110上的定位结构242和光学膜片121的防呆结构241都包括凹陷与凸台，这样每个支板240上的防呆结构241构成类似USB型结构，对应的，在背板110上的定位结构242也构成类似USB型结构与防呆结构241对应配合，因为USB型结构不仅实现上下的防呆，还实现左右的防呆，在我们组反射片、导光板或者光学膜片的时候出现零错误的情况，不仅提高了工作效率，也极大的提高了产品的良品率；光学膜片121安装时，会先将光学膜片121的安装始端与背板110的一端对齐，然后逐渐贴合，最后将光学膜片121的尾端与背板110的另一端对齐即可完成安装，考虑到防呆结构241对光学膜片121的安装起防呆与定位作用，因此在光学膜片121安装过程中，需要从安装开始时就将防呆结构241对齐，这样会提高安装准确率与效率，因此，本方案将支板240设置在主板230的安装始端，方便光学膜片121的安装；考虑到光学膜片121较薄，若第一凹陷310设计的深度较浅，会出现第二凸台210与第一凹陷310配合不牢固现象，因此，本方案将第一凹陷310设计为通孔311，这样第一凹陷310的深度达到最大，与第二凸台210配合后会达到最大稳定状态。考虑到背板110是背光模组100的基板，对光学膜片121起支撑和一定的保护作用，因此，本方案将光学膜片121上的第一凸台320的凸起的高度等于第二凹陷220的深度，这样安装时既能起到定位作用，而且安装后的第一凸台320不凸出于背板110内部，可以不受外界影响，同时也能起到定位作用，整体感更强；因为背板110上的定位结构242与光学膜片121上的防呆结构241都为类似USB型，那么配合后就需要考虑到，防呆与定位结构242不应影响光学膜片121的正常功能，同时因为背板110上通常会叠放安装多层光学膜片121，因此，本方案设计的第二凸台210凸起的高度等于第一凹陷310的深度，这样第二凸台210就不会出现穿过光学膜片121而突出的现象，就不会影响到其它层光学膜片121的安装；考虑到防呆结构241与定位结构242配合后，还要对光学膜片121起到限位作用，否则光学膜片121安装后不牢固，因此，通过尺寸设计，使得防呆结构241与定位结构242配合固定后为无间隙贴合，这样安装后的光学膜片121除安装方向外再无运动空间。
如图1至图7所示，公开了一种显示面板，显示面板包括背光模组100。
以上内容是结合具体的可选的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
