Description

背光模组及显示装置 技术领域
本发明涉及一种光源模组，并且特别涉及一种背光模组及使用此背光模组的显示装置。
背景技术
请参照图1，其是绘示一种习知显示装置的装置示意图。习知的显示装置900包含背光模组910、显示面板920、压板930、塑料框940以及外观前框950。背光模组910包含钣金件911、散热座912、光源913及导光板914。其中，散热座912设置在钣金件911中，光源913及导光板914分别设置在散热座912中。压板930主要用来压制导光板914并可同时承载显示面板920。塑料框940以及外观前框950固定在钣金件911上，形成显示装置900的边框区域，此边框区域具有宽度S1。
为了使压板930、塑料框940、以及外观前框950固定在背光模组910上，必须在钣金件911上设置可使压板930、塑料框940以及外观前框950结合的结构，例如，图1所示的从钣金件911侧面延伸出的螺柱960。然而此种设计并不利于显示装置900的窄边框设计。另一方面，习知的钣金件911因包覆整个散热座912也易导致散热座912的散热效果不佳。
发明内容
因此，本发明的目的是提供一种背光模组及显示装置，其可符合窄边框的设计需求。
根据本发明的上述目的，提出一种背光模组。此背光模组包含承载件、光源、导光板、组合架、以及外部组件。光源设置在承载件上。导光板设置在承载件上，其中导光板的入光面邻设于光源。组合架沿着第一方向结合于承载件的底部。外部组件沿着第二方向结合于组合架上。
依据本发明的一实施例，上述的承载件包含承载部以及立设于承载部的侧边的侧墙。光源与导光板设置在承载部上。组合架在第二方向上与承载件形成非共平面的让位设计以形成容置空间。组合架包含板体部以及第一嵌合壁。板体部抵靠承载部的底面。第一嵌合壁立设于板体部上，其中第一嵌合壁嵌入承载部的底面。其中，背光模组还包含装配结构，其中装配结构的至少一部分位于容置空间中，且装配结构将外部组件沿着第二方向结合于组合架上。
依据本发明的一实施例，上述的组合架还包含第二嵌合壁。第二嵌合壁立设于板体部上。第二嵌合壁嵌入承载部的底面，且第二嵌合壁与侧墙之间的距离大于第一嵌合壁与侧墙之间的距离。
依据本发明的一实施例，上述的容置空间由第一嵌合壁、承载部以及侧墙共同界定而成。装配结构设置在第一嵌合壁上。
依据本发明的一实施例，上述的装配结构包含设置在第一嵌合壁的外侧面的固定柱，其中固定柱沿着平行于第二方向的方向延伸以结合外部组件。
依据本发明的一实施例，上述的装配结构包含至少一个固定孔以及至少一个固定柱，其中固定孔穿过第一嵌合壁的外侧面，固定柱对应设置在固定孔中。其中，固定柱从第一嵌合壁的外侧面沿着平行于第二方向的方向延伸以结合外部组件。
依据本发明的一实施例，上述的板体部设有至少一个安装孔，其配置以供至少一个安装件沿着第一方向穿设以将板体部固定至承载部的底面。
依据本发明的一实施例，上述的外部组件包含压制单元，其中压制单元包含压制部以及侧板部。压制部具有抵靠侧墙的顶面以及导光板的光学面的压制面，侧板部连接于压制部且抵靠侧墙的外侧面。装配结构还包含第一固定柱及第一结合件，其中第一固定柱设置在组合架的第一嵌合壁上，第一结合件穿过压制单元的侧板部并固定在第一固定柱上。
依据本发明的一实施例，上述的装配结构的第一结合件具有头部及杆部，第一固定柱及第一结合件的杆部位于容置空间中，杆部穿过压制单元的侧板部并固定在第一固定柱中。
依据本发明的一实施例，上述的外部组件还包含外观件，外观件包覆在压制单元外。装配结构还包含第二固定柱及第二结合件，其中第二固定柱设置在组合架的第一嵌合壁上，第二结合件穿过外观件与压制单元的侧板部并固定在第二固定柱上。
依据本发明的一实施例，上述的组合架还包含从板体部延伸而出的第一L型结构，其中第一L型结构具有沿着第一方向延伸的第一结合面。外部组件包含压制单元，压制单元包含压制部以及侧板部，其中压制部具有抵靠侧墙的顶面以及导光板的光学面的压制面，侧板部连接于压制部且抵靠侧墙的外侧面。装配结构还包含第一组合件，第一组合件穿过压制单元的侧板部并固定在第一结合面上。
依据本发明的一实施例，上述的装配结构的第一组合件具有头部及杆部。其中，第一L型结构的第一结合面及第一组合件的杆部位于容置空间中，杆部穿过压制单元的侧板部并固定在第一L型结构上。

根据本发明的上述目的，提出一种显示装置。显示装置包含背光模组以及显示面板。显示面板设置在背光模组的前方。
由前述可知，本揭露的组合架沿着第一方向设置在承载件的下方，且沿着第二方向与承载件形成非共平面的让位设计而产生容置空间。借此，通过将用来固定外部组件的装配结构容设于容置空间的设计，可大幅缩减显示面板的边框宽度，进而达到窄边框的需求。另一方面，本揭露的组合架为条状结构且并未完全覆盖承载件，故可提升承载件的散热效果。

具体实施方式
以下实施例中所提到的方向用语，例如「X方向」与「Z方向」等，仅参考了附图中的方向。因此，所使用的方向用语仅用来说明，而非用来限制本发明。
请同时参照图2及图3，其是绘示依照本发明的第一实施方式的显示装置的立体示意图，图3是绘示沿着图2的A-A剖面线所剖切的剖面图，其中图2中的A-A剖面线的实际剖切位置与图5中A-A剖面线所剖切的位置相同。本实施方式的显示装置100主要包含背光模组200及显示面板110。显示面板110设置在背光模组200的前方。背光模组200主要包含承载件210、光源220、导光板230、组合架240、外部组件(例如压制单元250及/或外观件260)以及装配结构270。其中，承载件210主要用来承载光源220及导光板230，组合架240为条状结构，其主要设置在承载件 210的底部靠近光源220的一侧(也就是显示装置100的地侧)。组合架240主要可供外部组件通过装配结构270固定在承载件210上。
请同时参照图3及图4，其中图4是绘示依照本发明的第一实施方式的部分零件的局部分解图。要说明的是，为了方便说明的目的，图4仅绘示出了承载件210、组合架240、压制单元250与外观件260的一部分。承载件210从侧面看起来概呈L形，且承载件210包含承载部211以及立设于承载部211的侧边的侧墙212。其中，导光板230承载于承载部211上，光源220贴设在侧墙212上且邻设于导光板230的入光面231。在本实施例中，承载部211靠近侧墙212的部分具有隆起结构211a，隆起结构211a除了用来支撑导光板230外，亦具有增加整体结构强度的功能。在一些实施例中，承载件210本身为散热件，故光源220所产生的热可通过承载件210而散逸至外界。
请继续参照图3及图4，组合架240沿着第一方向(例如图3及图4所示的Z方向)结合于承载件210的底部。请一并参照图5，其中图5是绘示依照本发明的第一实施方式的组合件的结构示意图。在本实施例中，组合架240包含板体部241、第一嵌合壁242以及第二嵌合壁243。第一嵌合壁242与第二嵌合壁243分别立设于板体部241的相对两个侧边，以使组合架240从侧面看起来大概呈U形。如图3所示，板体部241抵靠承载部211的底面，第一嵌合壁242与第二嵌合壁243则嵌入承载部211中，如此，可增加组合架240与承载件210之间的结合稳定性。在一些例子中，板体部241设置有至少一个安装孔241a，其配置以供至少一安装件241b沿着第一方向(例如Z方向)穿设于其中，以将板体部241固定至承载部211的底面。
如图3及图4所示，第一嵌合壁242与承载件210的侧墙212的距离小于第二嵌合壁243与承载件210的侧墙212的距离，换言之，第一嵌合壁242比第二嵌合壁243更靠近侧墙212。在一实施例中，承载件210的侧墙212与第一嵌合壁242或第二嵌合壁243互相平行。在本实施例中，组合架240在第二方向(例如图3所示的X方向)上与承载件210形成非共平面的让位设计而形成容置空间A1。具体而言，组合架240设置在承 载件210的下方，且组合架240的侧墙212并非对齐第一嵌合壁242，而使第一嵌合壁242、承载件210的侧墙212及承载部211共同形成容置空间A1。此容置空间A1主要可用来容纳部分的用来固定外部组件(例如压制单元250及/或外观件260)的装配结构270。
请同时参照图4及图6，其中图6是绘示沿着图2的B-B剖面线所剖切的局部剖面图。其中图2中的B-B剖面线的实际剖切位置与图5中B-B剖面线所剖切的位置相同。在本实施例中，压制单元250沿着第二方向(例如图4及图6所示的X方向)结合在组合架240上。如图4及图6所示，压制单元250为L型结构，且具有压制部251以及连接于压制部251的侧板部252。压制部251具有压制面251a，其抵靠承载件210的侧墙212的顶面以及导光板230的光学面232。侧板部252抵靠于侧墙212的外侧面。在本实施例中，导光板230朝向压制部251的一侧、或导光板230被承载件210顶抵的一侧可设有缓冲垫(例如图6所示的缓冲垫C1及缓冲垫C2)，以避免导光板230受到外力冲击而容易发生破裂的情况。
在本实施例中，装配结构270包含第一固定柱271a及第一结合件271b。第一固定柱271a及第一结合件271b主要用来将压制单元250结合在组合架240上。具体而言，如图6所示，第一固定柱271a的一端固定在组合架240的第一嵌合壁242中，且另一端从第一嵌合壁242的外表面沿着平行于第二方向(例如图6中的-X方向)延伸至容置空间A1中。第一结合件271b则穿过压制单元250的侧板部252，而固定至第一固定柱271a中。其中，第一结合件271b具有头部271c及杆部271d，头部271c抵靠压制单元250的侧板部252的外表面，杆部271d穿过侧板部252且固定在第一固定柱271a中。经由第一结合件271b的设计，可以使得压制单元250在X方向上被第一结合件271b固定住，不会轻易移位而丧失了压制单元250持续抵靠导光板230的光学面232的压制效果。
请同时参照图4及图7，其中图7是绘示沿着图2的C-C剖面线所剖切的局部剖面图。其中图2中的C-C剖面线的实际剖切位置与图5中C-C剖面线所剖切的位置相同。在本实施例中，外观件260沿着第二方向(例如图4及图7所示的X方向)结合在组合架240上。如图4及图7所示， 外观件260包覆在压制单元250外。在本实施例中，装配结构270还包含第二固定柱272a及第二结合件272b。第二固定柱272a及第二结合件272b主要用来将外观件260结合在组合架240上。具体而言，如图7所示，第二固定柱272a的一端固定在组合架240的第一嵌合壁242中，且另一端从第一嵌合壁242的外表面沿着平行于第二方向的方向(例如图7中的-X方向)延伸至容置空间A1中。第二结合件272b则穿过外观件260与压制单元250的侧板部252，而固定至第二固定柱272a中。同样地，第二结合件272b具有头部272c及杆部272d，头部272c抵靠外观件260的外表面，杆部272d穿过外观件260以及压制单元250的侧板部252而固定在第二固定柱272a中。经由第二结合件272b的设计，可以使得外观件260与压制单元250同时被第二结合件272b限位固定，而且当使用者朝-Z方向观看显示装置100时，外观件260较为突出的部分能够遮蔽第二结合件272b的头部272c，以使锁附位置能够达到予以隐藏的效果。
请同时参照图4及图8，其中图8是绘示沿着图2的D-D剖面线所剖切的局部剖面图。其中图2中的D-D剖面线的实际剖切位置与图5中D-D剖面线所剖切的位置相同。装配结构270还包含固定柱273。固定柱273设置在容置空间A1中，且可通过嵌设的方式固定在第一嵌合壁242上的固定孔242a中，且固定柱273从第一嵌合壁242沿着平行于第二方向的方向(例如图8中的-X方向)延伸。在本实施例中，压制单元250的侧板部252上具有穿孔252a，当压制单元250沿着第二方向(例如图8中的X方向)组装至组合架240时，固定柱273的一部分位于穿孔252a中，可达到限位压制单元250的作用。
由前述可知，本揭露的实施方式取消了如图1所示的钣金件911的设计，另外采用了使条状的组合架240结合于承载件210底部的一侧，并应不同外部组件的加装需求，在第一嵌合壁242上设置不同长度的装配结构270的设计。这种不仅可将外部组件结合于结构强度相对较强的组合架240上，而且可通过组合架240与承载件210形成非共平面的让位设计所产生容置空间A1来容纳装配结构270的设计，可大幅缩减显示面板100的边框宽度(例如图6所示的宽度S2)，进而达到窄边框的需求。另一方 面，通过条状的组合架240的设计，亦可使承载件210外露，进而提升承载件210的散热效果。
在本揭露中，组合件亦可有不同的结构设计。请同时参照图9及图10，其是绘示依照本发明的第二实施方式的显示装置的立体示意图，图10是绘示沿着图9的E-E剖面线所剖切的剖面图，其中图9中的E-E剖面线的实际剖切位置与图12中E-E剖面线所剖切的位置相同。本实施方式的显示装置300主要包含背光模组400及显示面板310。显示面板310设置在背光模组400的前方。背光模组400主要包含承载件410、光源420、导光板430、组合架440、外部组件(例如压制单元450及/或外观件460)以及装配结构470。其中，承载件410主要用来承载光源420及导光板430，组合架440同样为条状结构，其主要设置在承载件410的底部靠近光源420的一侧(也就是显示装置300的地侧)。组合架440主要可供外部组件通过装配结构470固定在承载件410上。
请同时参照图10及图11，其中图11是绘示依照本发明的第二实施方式的部分零件的局部分解图。要说明的是，为了方便说明的目的，图11仅绘示出了承载件410、组合架440、压制单元450与外观件460的一部分。承载件410从侧面看起来概呈L形，且承载件410包含承载部411以及立设于承载部411的侧边的侧墙412。其中，导光板430承载于承载部411上，光源420贴设在侧墙412上且邻设于导光板430的入光面431。在本实施例中，承载部411靠近侧墙412的部分具有隆起结构411a，隆起结构411a除了用来支撑导光板430外，亦具有增加整体结构强度的功能。在一些实施例中，承载件410本身为散热件，故光源420所产生的热可通过承载件410而散逸至外界。
请继续参照图10及图11，组合架440沿着第一方向(例如图10及图11所示的Z方向)结合于承载件410的底部。请一并参照图12，其中图12是绘示依照本发明的第二实施方式的组合件的结构示意图。组合架440包含板体部441、第一嵌合壁442以及第二嵌合壁443。第一嵌合壁442与第二嵌合壁443分别立设于板体部441的相对两个侧边，以使组合架440从侧面看起来大概呈U形。如图10所示，板体部441抵靠承载部411 的底面，且第一嵌合壁442与第二嵌合壁443则嵌入承载部411中。在一些例子中，板体部441设置有至少一个安装孔441a，其配置以供至少一个安装件441b沿着第一方向(例如Z方向)穿设于其中，以将板体部441固定至承载部411的底面。
如图10及图11所示，第一嵌合壁442与承载件410的侧墙412的距离小于第二嵌合壁443与承载件410的侧墙412的距离，换言之，第一嵌合壁442比第二嵌合壁443更靠近侧墙412。在一实施例中，承载件410的侧墙412与第一嵌合壁442或第二嵌合壁443互相平行。在本实施例中，组合架440在第二方向(例如图10所示的X方向)上与承载件410形成非共平面的让位设计而形成容置空间B1。具体而言，容置空间B1由第一嵌合壁442、承载件410的侧墙412及承载部411共同形成。此容置空间B1主要可用来容纳部分的用来固定外部组件(例如压制单元450及/或外观件460)的装配结构470。
如图11及图12所示，组合架440还包含第一L型结构444与第二L型结构445。第一L型结构444与第二L型结构445分别从板体部441的设有第一嵌合壁442的侧边延伸至容置空间B1中。在本实施例中，第一L型结构444具有沿着第一方向(例如Z方向)延伸的第一结合面444a，第二L型结构445具有同样沿着第一方向(例如Z方向)延伸的第二结合面445a。其中，第二结合面445a与第一嵌合壁442之间的距离大于第一结合面444a与第一嵌合壁442之间的距离。此外，第一L型结构444主要用来供压制单元450固定于其上，第二L型结构445主要用来供外观件460固定于其上。
请同时参照图11及图13，其中图13是绘示沿着图9的F-F剖面线所剖切的局部剖面图。其中图9中的F-F剖面线的实际剖切位置与图12中F-F剖面线所剖切的位置相同。在本实施例中，压制单元450沿着第二方向(例如图11及图13所示的X方向)结合在组合架440上。如图11及图13所示，压制单元450为类L型结构，其具有压制部451以及连接于压制部451的侧板部452。压制部451具有压制面451a，其抵靠承载件410的侧墙412的顶面以及导光板430的光学面432。侧板部452抵靠于侧 墙412的外侧面。在本实施例中，装配结构470包含第一组合件471。第一组合件471主要用来将压制单元450结合在组合架440上的第一L型结构444上。具体而言，如图13所示，第一组合件471穿过压制单元450的侧板部452而固定至第一L型结构444的第一结合面444a中。其中，第一组合件471具有头部471a及杆部471b，头部471a抵靠压制单元450的侧板部452的外表面，杆部471b穿过侧板部452而固定在位于容置空间B1中的第一L型结构444上。经由第一组合件471的设计，可以使压制单元450在X方向上被第一组合件471固定住，不会轻易移位而丧失了压制单元450持续抵靠导光板430的光学面432的压制效果。
请同时参照图11及图14，其中图14是绘示沿着图9的G-G剖面线所剖切的局部剖面图。其中图9中的G-G剖面线的实际剖切位置与图12中G-G剖面线所剖切的位置相同。在本实施例中，外观件460沿着第二方向(例如图11及图14所示的X方向)结合在组合架440上。如图11及图14所示，外观件460包覆在压制单元450外。在本实施例中，装配结构470包含第二组合件472。第二组合件472主要用来将外观件460结合在组合架440上的第二L型结构445上。具体而言，如图14所示，第二组合件472分别穿过外观件460以及压制单元450的侧板部452而固定至第二L型结构445的第二结合面445a上。其中，第二组合件472具有头部472a及杆部472b，头部472a抵靠外观件460的外表面，杆部472b穿过外观件460及压制单元450的侧板部452而固定在第二L型结构445上。经由第二组合件472的设计，可以使外观件460与压制单元450同时被第二组合件472限位固定，而且当使用者朝-Z方向观看显示装置300时，外观件460较为突出的部分还能遮蔽第二组合件472的头部472a，以使锁附位置能够达到予以隐藏的效果。
请同时参照图11及图15，其中图15是绘示沿着图9的H-H剖面线所剖切的局部剖面图。其中图9中的H-H剖面线的实际剖切位置与图12中H-H剖面线所剖切的位置相同。装配结构470还包含固定柱473。固定柱473设置在容置空间B1中，且可通过嵌设的方式固定在第一嵌合壁442上的固定孔442a中并从第一嵌合壁442沿着平行于第二方向的方向(例如 图15所示的-X方向)延伸。在本实施例中，压制单元450的侧板部452上具有穿孔452a，当压制单元450沿着第二方向(例如X方向)组装至组合架440时，固定柱473的一部分位于穿孔452a中，可达到限位压制单元450的作用。
由前述可知，本揭露的实施方式取消了如图1所示的钣金件911的设计，另外采用了使条状的组合架440结合于承载件410底部的一侧，并应不同外部组件的加装需求，在第一嵌合壁442上设置不同长度的装配结构470的设计。这种不仅可将外部组件结合于结构强度相对较强的组合架440上，且通过组合架440与承载件410形成非共平面的让位设计所产生容置空间B1来容纳装配结构470的设计，可大幅缩减显示面板300的边框宽度(例如图13所示的宽度S3)，进而达到窄边框的需求。另一方面，通过条状的组合架440的设计，亦可使承载件410外露，进而提升承载件410的散热效果。
虽然本发明已通过实施例进行了如上揭露，然而其并非用以限定本发明。任何本领域技术人员，在不脱离本发明的精神和范围内，应当可以做出些许修改与润饰，故本发明的保护范围应当以所附权利要求书所界定的范围为准。
