Description

导光板可导引定位的背光模组及显示器 技术领域
本发明涉及一种背光模组，特别是涉及一种导光板可导引定位的背光模组及应用有该背光模组的显示器。
背景技术
如图9所示，现今的背光模组包含框架90、导光板91及光条92，导光板91设置于框架90上，光条92设置于框架90的一侧，并与导光板91相邻设置，光条92能对导光板91的入光侧投光，使导光板91朝与框架90相对的另一面出光。
为了将导光板91定位于框架90中，框架90上远离光条92的另一侧设置多个具有弹性的定位部件93，定位部件93包含相连接的基部931及推抵部932，基部931黏贴设置于框架90，并位于导光板91下方，推抵部932连接基部931，而使定位部件93呈L形，且推抵部932接触框架90的侧墙，在装配导光板91时，导光板91的与入光侧相对的另一侧接触并挤压推抵部932，由此通过推抵部932弹性回复的推力而使导光板91的入光侧接触光条92，以将导光板91定位。
然而，定位部件93的推抵部932须抵靠框架90的侧墙及导光板91，才能产生使导光板91定位的推力，而推抵部932的宽度会造成导光板91的宽度受限，导致背光模组的出光面积缩小，不利于窄边框的设计，且存在导光板91会被定位部件93的推抵部932顶撑的风险，因此仍有改善的空间。而此种设计也容易受到制程与组装的影响，所以相对精度较差。因组装时使用胶带贴附固定，故对于部材的重工性较差。综上所述，现行背光模组在导光板的限位固定结构上，都须要额外部材进行限位，并且需追加多个前置工站进行配合组装，这不仅影响组装工时也增加制作成本。
发明内容
本发明的主要目的在于提供一种导光板可导引定位的背光模组，希藉此改善现今的背光模组的导光板的定位结构的设计会影响导光板的宽度，导致现今的背光模组的出光面积缩小，且不利于窄边框设计的问题。
为了达成前揭目的，本发明的导光板可导引定位的背光模组包含：
框架，其包含相连接的底框及侧壁；
光条，其设置于侧壁；
至少一个定位件，定位件设置于底框，并具有第一组装部；及
导光板，其设于框架内，且位于定位件上方，并于朝向定位件的一侧设有至少一个第二组装部，第二组装部的位置对应于定位件的第一组装部，当第二组装部沿组装方向与位置对应的第一组装部结合时，导光板会被推抵而沿定位方向朝侧壁移动。
于本发明的背光模组中，导光板位于定位件上方，藉由第二组装部沿组装方向与定位件的第一组装部结合，并被推抵而沿定位方向朝侧壁移动，由于定位件设置于框架的底框上，而导光板的第二组装部设于朝向定位件的一侧，且第二组装部沿组装方向与第一组装部结合而限位，因此导光板无需进一步藉助其他弹性橡胶体来辅助定位，这不仅可以降低材料成本，而且不会影响导光板于定位方向上的宽度，故不会影响背光模组的出光面积，有利于窄边框的设计，使得导光板可以同时达到固定与限位的需求，并改善导光板被定位件顶撑的风险，定位件也无需使用胶带固定，可以减少材料成本及重工造成的材料损耗，而由于使用的部材较少，因此组装工时较短，且较不易受到制程与组装的影响，所以相对精度较高。

具体实施方式
请参阅图1至图3，为本发明的导光板可导引定位的背光模组的较佳实施例，其包含框架10、光条20、至少一个定位件30及导光板40。
如图3及图4所示，框架10包含相连接的底框11及侧壁12。
如图1至图4所示，光条20设置于侧壁12。
如图1至图4所示，定位件30设置于底框11，并具有第一组装部31。
如图1至图4所示，导光板40设于框架10内，且位于定位件30上方，并于朝向定位件30的一侧设有至少一个第二组装部41，第二组装部41的位置对应于定位件30的第一组装部31，如图5及图6所示，第二组装部41沿组装方向D1与位置对应的第一组装部31结合时，导光板40会被推抵而沿定位方向D2朝侧壁12移动。
由于定位件30设置于框架10的底框11上，导光板40位于定位件30上方，而第二组装部41形成于导光板40朝向底框11的一侧，且第二组装部41沿组装方向D1与第一组装部31结合而限位，使导光板40在定位方向D2上的宽度不会受到定位件30限制，因此导光板40无需进一步藉助其他弹性橡胶体来辅助定位，这不仅可以降低材料成本，而且不会影响导光板40的与底框11相对的另一面的出光面401的出光面积，有利于背光模组的窄边框设计，使得导光板40可以同时达到固定与限位的需求，改善导光板40被定位件30顶撑的风险，定位件30也无需使用胶带进行固定，可 以减少重工造成的材料损耗。此外，由于导光板40的侧缘无须增加用以定位的结构，这可使导光板40的侧缘能保持平整，而能避免背光模组的光学品味受到影响。
再者，定位件30为可压缩的弹性材料，第二组装部41沿组装方向D1与位置对应的第一组装部31结合时，会压缩定位件30，定位件30的弹性回复力会推抵第二组装部41，而使导光板40沿定位方向D2朝侧壁12移动，通过定位件30为弹性材料的设计，能增加第一组装部31推抵第二组装部41的推力，从而能提升结合的稳定性。在本实施例中，组装方向D1与定位方向D2相互垂直，而在其他实施例也可以设计为组装方向D1与定位方向D2不相互垂直亦不相互平行，所以并不以本实施例的揭露为限。
于本发明的较佳实施例中，如图5所示，定位件30的第一组装部31呈凹孔状，导光板40的第二组装部41呈柱状，第二组装部41能伸入位置对应的第一组装部31中，以提升第一组装部31及第二组装部41结合的稳定性，且当背光模组受撞击等外力影响，造成导光板40与定位件30略微分离时，通过第一组装部31与第二组装部41呈凹孔及凸柱的配合的设计，能避免定位件30将导光板40顶起，以降低定位件30与导光板40分离的风险。
如图5所示，第一组装部31的中心沿定位方向D2至侧壁12的距离界定为第一距离L1，与第一组装部31位置对应的第二组装部41的中心沿定位方向D2至侧壁12的距离界定为第二距离L2，第一距离L1小于等于第二距离L2，当将导光板40的第二组装部41沿组装方向D1伸入位置对应的定位件30的第一组装部31，以进行导光板40的组装作业时，由于第一距离L1小于第二距离L2，也就是定位件30的第一组装部31的凹孔与导光板40的第二组装部41的凸柱是轴心错位的设计，如图6所示，此时，可以利用定位件30的弹性变形特性，使得定位件30被第二组装部41挤压而变形，并于变形回复时产生推力而推抵第二组装部41，使导光板40沿定位方向D2移动，此时，若第一组装部31与第二组装部41之间没有间隙而使第一距离L1等于第二距离L2时，定位件30的凹孔与导光板40的第二组装部41两者的轴心都位于相同位置，如图4所示，会使导光板40自 行达到固定与限位的需求。因此，工作人员在组装时无需将导光板40的第二组装部41与定位件30的第一组装部31对准在同一轴心，这可以减少人员组装造成的偏移误差。而若第一组装部31与第二组装部41呈紧配合固定，即第一组装部31与第二组装部41的轮廓相对应，则能进一步提升结合稳定性。
较佳地，第一组装部31呈长条凹孔状，藉由长条凹孔状的设计能保留较多的制造及装配裕度，而可提升制造及组装导光板40及定位件30的便利性，并能便于工作人员辨认定位件30的方向，且无须另于定位件30上设计标示，由此可提升制造的便利性，其中，第一组装部31的长边与侧壁12平行的设计，能增加第一组装部31推抵第二组装部41的面积，以提升推抵的稳定性，另外再搭配第一组装部31的长边与光条20平行的设计，可确保第一组装部31的延伸方向平行于光条20，并不会在垂直于光条20的方向上超出面板的非可视区，由此能避免导光板40的第二组装部41影响导光板40的主要出光区域，以避免影响背光模组的光学品味。
另外，侧壁12形成于底框11的边缘上方，并包含至少一个侧边，侧边位于底框11的至少一侧，或环绕底框11，导光板40被推抵而沿定位方向D2朝侧壁12移动时，会朝侧壁12的其中一个侧边移动，而光条20设置于侧壁12上与导光板40沿定位方向D2相对应位置的侧边上，则当导光板40的第二组装部41与定位件30的第一组装部31结合时，导光板40会朝向光条20移动。无论光条20是否设置于与导光板40沿定位方向D2相对应的位置，皆不影响导光板40的定位效果，因此能供厂商依产品需求而选择。
此外，光条20包含基板21及间隔设置于基板21的多个发光单元22，且基板21被定位件30抵靠定位于侧壁12上，多个发光单元22朝向导光板40，藉由定位件30推抵并固定基板21，使光条20的基板21无须布胶就可以黏贴于侧壁12，这能减少材料成本及装配工序，提升装配便利性，当需要调整光条20的位置时亦无须清除残胶并重新黏贴，而能减少重工造成的损耗及清洁残胶耗费的时间。
于本发明的较佳实施例中，光条20设置于侧壁12上与导光板40沿定 位方向D2相对应的位置，如图2所示，导光板40朝向光条20的一侧形成有至少一个定位凸块42，第二组装部41沿组装方向D1与位置对应的第一组装部31结合时，导光板40会被推抵而沿定位方向D2朝光条20所设置的侧壁12移动，直到导光板40的定位凸块42接触光条20而定位，藉此提升光条20的装配稳定性。
其中，若第一组装部31于定位方向D2上的宽度大于第二组装部41的宽度，使得第一组装部31及第二组装部41之间形成有间隙，且第一距离L1小于第二距离L2时，由于第二组装部41远离光条20的一侧会被定位件30推抵，而导光板40的定位凸块42会推抵光条20，因此导光板40于定位方向D2上仍受到两个相反方向的推力，藉此使导光板40能被定位而固定。
此外，定位凸块42的高度大于多个发光单元22的高度，且定位凸块42抵靠光条20的基板21，因此可以确保导光板40与基板21之间的距离维持一定，避免导光板40于运送过程或热膨胀过程中挤压发光单元22而造成发光单元22毁损。较佳地，导光板40的定位凸块42位于导光板40的角落处，由于定位凸块42的所处位置较容易出现聚光的不利影响，所以将定位凸块42设计在导光板40的角落处，而非位于导光板40的主要发光区，可以避免背光模组的主要发光区的光学品味受影响，更佳地，当导光板40的两侧角落处皆具有定位凸块42时，光条20的两端被两个定位凸块42平均地接触推抵，进而能提升固定光条20的稳定性。
于本发明的较佳实施例中，底框11形成有至少一个装配槽111，定位件30固定于装配槽111中，这可提升定位件30的装配稳定性，且能减少工作人员在组装定位件30时因装设偏移而导致精度下降的可能性，其中，定位件30能以不同方式固定于装配槽111中，例如定位件30能直接嵌入底框11的装配槽111中，并与装配槽111呈紧配合而固定，藉此无须以胶带黏贴于底框11，而能减少黏贴材料及重工的成本；而若以胶带将定位件30黏贴固定于装配槽111中，则能进一步提升装配稳定性；此外，当定位件30具有弹性时，藉由弹性变形，能使定位件30更紧密地嵌合于装配槽111，而能提升装配稳定性，而且也能利用定位件30支撑导光板40，以避 免导光板40于此处产生下垂现象。
另外，如图1所示，厂商能依据产品设计需求而于底框11上设置多个定位件30，导光板40对应多个定位件30而凸设有多个第二组装部41，每一第二组装部41分别与每一定位件30的第一组装部31结合，以提升装配稳定性，此外，装设于框架10上不同位置的定位件30皆互相通用，而无须配合框架10的内部轮廓重新设计定位件30的外型结构，由此减少开模、制造的成本，工作人员于组装时亦无须费时判断定位件30的组设位置，藉此能提升装配便利性，且由于样式简单，因此设计样品制作的时效性较快，而能缩短开发时程，且多个定位件30若沿与定位方向D2垂直的方向设置于底框11上，则能进一步使定位件30的对导光板40产生较大的推力，而提升装配稳定性。于本发明的较佳实施例中，装配槽111可以是单一条状，多个定位件30间隔地嵌设于单一条状的装配槽111中，以提升装配及制造的便利性，而单一条状的装配槽111可以沿定位方向D2延伸，而且定位件30于装配槽111之中排列为同一排，避免不同排时容易产生互相干涉的效果，或者，底框11可配合定位件30形成有多个装配槽111，每一定位件30能分别对应嵌设于其中一个装配槽111中，而能提升装配稳定性及定位的精确性。
再者，装配槽111与侧壁12设置光条20的位置相邻的设计，使装配槽111能提供装设光条20所需的空间，而无须于底框11上另外增加结构，以提升制造的便利性，且由于导光板40的第二组装部41对应嵌设于位在装配槽111中的定位件30，而位于较接近光条20的位置，藉此能避免导光板40及背光模组的光学品味受到影响，但是定位件30也可以设计于侧壁12除了邻近光条20以外的其他位置，所以并不以本实施例的揭露为限。光条20的基板21能伸入装配槽111中，并被定位件30紧迫固定，进一步提升光条20于装配槽111内的装配稳定性。
在本发明的较佳实施例中，组装方向D1与定位方向D2相互垂直，以增加第一组装部31对第二组装部41产生的推力，而能提升第一组装部31与第二组装部41结合的稳定性，且定位方向D2与导光板40的出光面401平行，因此组装方向D1垂直于出光面401，因此当工作人员组装导光板40 时，仅需将导光板40的第二组装部41垂直地伸入定位件30的第一组装部31即可，这能提升组装的便利性。
如图7所示，背光模组包含反射片50，反射片50位于导光板40与底框11之间，并形成有至少一个限位孔51，限位孔51的位置对应于导光板40的第二组装部41的位置，第二组装部41穿过限位孔51，再与对应的第一组装部31相结合，现有背光模组的反射片没有被定位，仅是设于导光板与框架之间，这容易产生偏移并影响光学品味，而于本发明的背光模组中，藉由第二组装部41将反射片50定位，能避免反射片50因偏移而影响光学品味，其中，反射片50具有一个或多个限位孔51，当导光板40具有呈直线排列的多个第二组装部41时，反射片50具有长槽状的限位孔51，多个第二组装部41能同时伸入限位孔51中以将反射片50定位，以提升制造的便利性；或于本发明的较佳实施例中，反射片50对应多个第二组装部41而形成有多个限位孔51，每一限位孔51分别能供每一第二组装部41伸入，藉此进一步提升定位效果，以提升光学品味，减少光学品味发生异常的风险，更佳地，限位孔51的轮廓与第二组装部41相匹配，而能提升定位效果。
此外，于现今的背光模组中，底框上需要形成用以装设光条的组装空间，当将反射片设置于底框上时，由于组装空间会于反射片的下方形成空隙，为了避免反射片弯折下垂，需要在组装空间中另外设置用以支撑反射片的支撑结构，反观于本发明的背光模组中，当底框11的装配槽111与侧壁12设置光条20的位置相邻时，装配槽111能提供装设光条20所需的空间，而定位件30会嵌设于装配槽111中，并向反射片50提供支撑，避免反射片50于此处产生下垂现象，藉此无须另于底框11上装设用以支撑反射片50的支撑结构，由此能精简背光模组的构件，进而减少成本并提升可靠度，且能减少组装造成的误差导致精度下降的风险。
再者，于组装现今的背光模组时，需先组装用以定位导光板的定位部件，再组装光条及前述的支撑结构，这需耗时约120秒，而于组装本发明的背光模组时，仅需要将光条20放置于框架10中，并将定位件30装设于装配槽111中，而无须另外装设支撑结构，因此仅需耗时约60秒，能有效 减少组装工时。此外，由于现今的背光模组的光条在布胶后才能黏贴于框架中，导致光条难以完整地自框架中拆除，容易造成材料损耗并且无法进行重工，支撑结构亦是通过黏贴而固定于框架中，为避免支撑结构于拆除时撕裂，工作人员需小心地进行拆除，再重新上胶黏贴，其重工需耗时约100秒，反观本发明的背光模组，由于光条20并非透过黏贴而固定，且本发明中亦没有装设支撑结构，因此无须重工，可以减少重工造成的材料损耗，并能轻易地调整光条20的位置，提升便利性。
请参阅图8，为本发明的显示器的较佳实施例，其包含上述背光模组及显示面板60，显示面板60设置于框架10，并位于导光板40的与底框11相对的另一侧，本发明的显示器藉由应用背光模组，能避免出光面积受背光模组的结构影响，进而提升光学品味，并能达到窄边框的设计。
综上，本发明的导光板可导引定位的背光模组的导光板40的第二组装部41通过与定位件30的第一组装部31相结合，就能将导光板40定位，且定位件30亦能用以将光条20定位，而能减少布胶成本及组装工时，并减少背光模组中使用的构件，以降低生产成本、构件的组装工差、重工损耗及组装的工时，并增加产品的良率。此外，本发明的背光模组还可以运用在车载显示装置之中。
虽然本发明的实施例已揭露如上，然而其并非用以限定本发明，本发明所属技术领域的技术人员，在不脱离本发明精神和范围内，应当可以做出些许更动与润饰，因此本发明保护范围应当以所附的权利要求书所界定的保护范围为准。
