本发明提出一种背光模组100。
请参照图1至图3,在本发明的一实施例中,背光模组100包括背板10、光源20及导光板30;所述背板10具有相对设置的第一面11和第二面12;
所述导光板30包括出光部31和弯折部32,所述出光部31设于所述第一面11,所述弯折部32由所述出光部31的一端朝向所述背板10的第二面12弯折延伸形成,所述弯折部32具有位于所述第二面12的入光端;所述光源20设于所述第二面12,并与所述入光端的入光端面3221相对应。
本实施例中,背光模组100为侧入式背光模组100,其包括背板10、光源20及导光板30,背板10呈平面板状,一般地,可设为长方体板状。光源20可以是灯条,或是多个灯珠21组成的条形发光体,安装于背板10的第二面12,也即背面,可选的,光源20包括基体和多个灯珠21,灯珠21为LED灯,成本低且出光稳定,通过一体的基底22安装于背板10上,提高组装效率。此处,该基底22可以是柔性电路板或印刷线路板,在提供固定的同时,还可以实现电连接,对灯珠21进行供电,有效减少组装部件。可以理解的,导光板30包括出光部31和弯折部32,出光部31设于第一面11,即背板10的正面,并具有出光侧,弯折部32则位于出光部31的一端面,并朝向背板10的第二面12弯折延伸,此处,弯折部32绕背板10的边缘弯折,从而可以有效减少两者的间隙,从而减少边框的尺寸。光源20与导光板30可以均通过粘接的方式固定于背板10,简单方便。粘接材料可以是液体胶,也可以是固体胶,或是固定胶条,例如,单面胶或双面胶等,从而实现稳定安装,且可以减少占用空间,有效压缩背光模组100的厚度。
为了提高光的利用率,光源20靠近背板10的边缘设置,而弯折部32弯折至少180度,从而在弯折180度时,其入光端面3221与光源20刚好正对,且部分位于背板10的第二面12,也即弯折部32具有与背板10相平行的表面,并朝向光源20延伸。导光板30的入光端面3221朝向光源20的出光侧,光源20发出的光线进入弯折部32内,光经过全反射传递到出光部31,从出光部31的上表面发出,实现面光源20。同时,光源20和出光部31之间通过背板10隔开,可进一步减少光源20对出光部31的热辐射影响,进而延长导光板30的使用寿命。同时,为了进一步提高安全性,将灯珠21与弯折部32间隔一定的安全间距,此处,安全间距可以无关边框尺寸,故而,设置的值可以大一点,有效避免导光板30的受热膨胀的挤压,提高防护性。
本发明技术方案的背光模组100包括背板10、光源20及导光板30,导光板30包括出光部31和由出光部31的一端弯折延伸形成的弯折部32,出光部31设于背板10的第一面11,光源20设于第二面12,弯折部32的部分设于背板10的侧面,入光端位于背板10的第二面12,入光端的入光端面3221接收光源20发出的光。此处,具有弯折部32的导光板30和设于第二面12的光源20,可以减少因光源20的尺寸而对边框的制约,有效实现窄边框;在导光板30因受热膨胀时,也使得光源20与导光板30的间距不至于过小,有效保护光源20不受损,且利用背板10的延伸空间,有效减少厚度方向的尺寸或边框的尺寸。同时,通过弯折部32具有位于背板10的第二面12的入光端,在光源20射向入光端面3221时,通过该部分的抵挡,使得光线顺利进入弯折部32内,减少光线直射至弯折弧线而直接反射回来的几率,有效保证背光模组100的导光和出光效果。且,具有位于第二面12的入光端还可以使得导光板30可夹设于背板10的边缘,从而有效保证两者的安装稳定性和相对位置,提高背光模组100的结构稳定性。
请继续参照图3,可选的实施例中,所述弯折部32包括弯曲段321和直线段322,所述弯曲段321连接所述出光部31和所述直线段322,所述直线段322为所述入光端,所述直线段322具有平行于所述出光部31表面的表面和垂直于所述出光部31表面的入光端面3221。
本实施例中,弯折部32包括了弯曲段321和直线段322,该弯曲段321即位于背板10的侧面的部分,用于过渡连接出光部31和直线段322,直线段322则位于第二面12,即背板10的下表面,为上述的入光端,具有平行于出光部31的表面和垂直于出光部31的入光端面3221,也即直线段322为矩形,如此,可以使得光源20发出的光能够尽可能多地被直线段322所接收,接近于目前的平面状的导光板30接收的光量,故可在减少边框尺寸的基础上,并不影响导光板30的导光量和导光效果。
请结合图4至图7,可选的实施例中,在所述背光模组100的纵切面上,所述弯曲段321背离所述背板10的一侧呈弧线或折线;
和/或,所述出光部31与所述弯折部32围合形成的朝向所述背板10的表面为U型面。
此处,弯折部32由出光部31进行弯折延伸形成,此处,并不限定该弯折部32的形状。可选的,在背光模组100的纵切面上,弯曲段321背离背板10的一侧可以是弧线,例如,圆弧线,从而使得弯曲段321具有光滑的圆弧表面,方便加工组装,提高安全性。或者弯曲段321背离背板10的一侧呈折线,例如,两段相连的直线,从而使得弯曲段321具有锥面,减少弯折段的材料;或呈多段首尾相连的直线,弯曲段321具有多个相连的平面,可以根据实际情况进行尺寸的设计,以方便组装和提高安装稳定性。
在弯曲段321背离背板10的表面呈圆弧面或锥面等的基础上,因弯折部32至少弯折180度,故设置出光部31与弯折部32围合形成的朝向背板10的表面为U型,从而与背板10的周缘更加匹配,进一步提高安装准确度和稳定性。
请再次参照图3,可选的实施例中,所述弯折部32背离所述背板10的表面的至少部分设有第一反射件40;
和/或,所述出光部31与所述背板10之间设有反射片50。
本实施例中,为了防止漏光,在弯折部32背离背板10的表面设置有第一反射件40,第一反射件40可以是反射镀层,也可以是反射片50,贴合在弯折部32的表面,可以将从弯折部32内透射出的光线进一步反射,使其返回导光板30内,继续从出光部31的出光侧射出,在提升出光量的同时,还可以提高光源20的效率。此处,可以是弯折部32背离背板10的表面全部设置第一反射件40,如弯曲段321和直线段322背离背板10的表面,从而能够最大程度提升出光量;当然,也可是在弯折部32的部分区域设置第一反射件40,如,仅是在弯曲段321背离背板10的表面。
可以理解的,在光线经过入光端面3221进入弯曲段321后,经过全反射或部分透射再反射后,进入出光部31,在出光部31的上下两表面进行反射传递,为了保证光线均经过反射后从上表面的出光侧射出,在导光板30与背板10之间设置反射片50,该反射片50的材质一般为PET与TiO2的合成材料,具有较好的反射效果,可以将避免光线从出光部31的下表面射出,有效提升出光量。当然,其他实施例中,还可以选择金属反射结构等。
请结合图2和图3,可选的实施例中,所述弯折部32的厚度小于所述出光部31的厚度;
和/或,所述背板10朝向所述弯折部32的端面为曲面;
和/或,所述背板10朝向所述弯折部32的端面涂覆有防护层60。
为了进一步方便弯折,将导光板30的厚度尺寸设置不均一,即弯折部32的厚度小于出光部31的厚度,此处,减薄弯折部32的厚度,可以方便弯折加工,保证弯折的效果,提高弯折部32的结构稳定性。当然,为了进一步提升弯折效果,将弯折部32的厚度由靠近出光部31的一端至入光端面3221的方向上逐渐减薄,从而避免出现应力集中的区域和死角,保证弯折部32的结构强度和导光效果,同时还可以进一步减少弯折部32对窄边框设计的制约,减少边框的尺寸。当然,于其他实施例中,也可以将弯折部32的厚度呈阶梯状或不规则方式减薄。
因弯折部32绕过背板10的边缘从而形成朝向光源20的入光端面3221,为了避免背板10的边角将导光板30的表面刮伤或损坏,将背板10朝向弯折部32的端面设置为曲面,例如,将背板10的边角进行倒角设置,或将背板10的端面设置为圆弧面等,从而具有光滑的接触面,有效提升对弯折部32的保护,提高产品良率。当然,于另外一实施例中,可以在背板10的端面涂覆有防护层60,该防护层60可以是防刮花膜层或耐磨层等,也可以减少背板10与导光板30之间的摩擦损坏,提升产品使用性能。可选的,在出光部31与背板10之间设置反射片50时,可以将防护层60向第一面11延伸抵接反射片50,同时向第二面12延伸,抵接光源20,实现最大面积的防护。
当然,又一实施例中,可以在背板10的端面上既设置为曲面,又涂覆防护层60,从而得到更好的防护效果。
请结合图3,此外,为了提高出光效率和出光效果,背光模组100还包括光学调控件70,也即光学膜片,光学调控件70设于出光部31的上方,从而能够形成效果更好的出射光。此处,光学调控件70可以是棱镜片、增亮片或扩散板等,棱镜片可以提高光的均匀度,增亮片可以增加出射光的亮度,扩散板可以增加出射光的出射角度,且保证边缘也能接收足够的光线,从而提升边缘位置的亮度,从而提供更为均匀且稳定的光源20。当然,也可以设置多个依次叠设的光学调控件70,从而进一步提升背光模组100的出射光线的均匀性和稳定性。
请结合参照图4至图7,本发明还提出一种显示设备900,所述显示设备900包括显示面板800和如上任一所述的背光模组100,所述显示面板800设于所述出光部31的出光侧。由于本发明的显示设备900的背光模组100应用了上述任一实施例的背光模组100,因此,由上述实施例带来的有益效果,在此不做赘述。
请结合图2和图5,可选的实施例中,所述显示设备900还包括支架91,所述支架91包括固定部911和设于所述固定部911一端的遮光部912,所述固定部911安装于所述第二面12,所述遮光部912朝向所述光源20的方向延伸并遮盖所述光源20背离所述背板10的一侧。
本实施例中,结合光源20是设于第二面12,即倒挂于背板10上,故而,光源20发出的光线会朝向背离背板10的方向,于此,设置有一固定于背板10的支架91,该支架91具有遮光部912,该遮光部912可以遮盖光源20背离背板10的一侧,也即,固定部911固定于背板10的第二面12,并与光源20的基底22间隔设置,遮光部912呈片状或板状,一端连接于固定部911背离背板10的表面,另一端朝向光源20的方向延伸,并位于光源20的下表面,能够完全覆盖光源20,从而实现遮光效果,防止光源20从背光模组100的背棉漏出。该固定部911可以通过粘接或焊接的方式固定于背板10,也可以通过卡接或插接等可拆卸的方式连接。支架91的材质可以是金属,从而具有较好的遮光效果,同时,也可以有利于光源20的散热。
当然,可选的,还可以将遮光部912抵接光源20,也即抵接灯珠21,从而可以为光源20提供一定的支撑力,进一步保证背光模组100的结构稳定性。
可选的,所述遮光部912朝向所述光源20的表面设有第二反射件914,在有效遮盖光源20朝向背板10的背面发射的光线下,为了有效利用此部分光线,设置第二反射件914位于遮光部912与光源20之间,从而将此部分光线反射,增加进入导光板30的几率,提升光源20的利用率。
请继续参照图2和图5,可选的实施例中,所述显示设备900还包括中框92,所述中框92包括底部921和连接于所述底部921边缘的侧部922,所述底部921支撑于所述遮光部912背离所述光源20的表面,所述侧部922贴合连接于所述弯折部32背离所述背板10的表面。
当然,为了使得光源20与导光板30的安装更加稳定,显示设备900还包括有中框92,该中框92包括底部921和侧部922,两者成夹角设置,侧部922设于弯折部32背离背板10的一侧,可以对弯折部32进行横向限位,故侧部922的内表面与弯折部32的外表面相适配,还可以保证第一反射件40的安装稳定性。侧部922还可以为显示面板800提供支撑作用,从而使得导光板30与显示面板800之间保留一定的出光距离。底部921具体与侧部922为垂直关系,朝向光源20所在的一侧延伸,可以对弯折部32和光源20在纵向方向的限位。可选的,底部921可抵接支撑遮光部912,进一步提升结构紧凑度和稳定性。
侧部922和底部921的材质可以均是塑料或金属,当为塑料材质时,两者可以注塑一体成型;当为金属材质时,两者可以冲压后折弯成型,结构强度和稳定性好,可以起到较好的支撑作用和保护作用。当然,于一实施例中,光源20可以设于中框92上,即安装在底部921朝向导光板30的表面,从而可以节省支架91的材料。此时,可以将第二反射件914设置在底部921朝向光源20的表面,提升光的利用率。
请参照图5和图7,所述显示设备900还包括主控板93,可选的实施例中,所述支架91还包括设于所述固定部911另一端的安装部913,所述主控板93安装于所述安装部913和所述遮光部912背离所述光源20的表面,并与所述显示面板800和光源20均电连接。
可以理解的,显示设备900还包括有主控板93,用于为显示面板800提供显示画面的数据和扫描电压,此处,将主控板93设置在背板10的下表面,支架91还包括安装部913,该安装部913也呈板状,并设于固定部911背离遮光部912的一端,主控板93安装在安装部913和遮光部912背离光源20的表面,并与中框92间隔设置,该结构的设置可以简化结构,将遮盖光源20和固定主控板93的结构合为一体,提升显示设备900的集成度。且遮光部912和安装部913结合安装主控板93,能够在提升结构稳定性的同时,减少支架91的面积占用。
此处,遮光部912和安装部913均朝向背离背板10的一侧延伸一定长度,在朝向相反的方向延伸,从而使得三者围合形成一个避空腔,在主控板93安装在安装部913和遮光部912时,可以部分正对避空腔,有效提升主控板93的散热效果。进一步的,安装部913与遮光部912为一体成型结构,且材质为金属片,可以通过折弯的方式加工形成,简单方便,有效提升加工效率,并能够进一步提升散热效果。且金属材质的支架91可以主控板93与背板10上的接地信号连接,有利于接地。
当然,于其他实施例中,也可以将主控板93设于遮光部912背离光源20的表面,或者仅安装在安装部913背离背板10的表面。
请结合图2和图5,可选的实施例中,所述显示面板800包括相对设置的阵列基板801和彩膜基板802,所述阵列基板801超出所述彩膜基板802的部分通过覆晶薄膜94与所述主控板93电连接,所述覆晶薄膜94贴合于所述中框92背离所述导光板30的表面延伸设置,所述中框92开设有容纳所述覆晶薄膜94的晶片942的容纳槽9221。
可以理解的,在阵列基板801上设有控制每个像素开启的薄膜晶体管,故而将阵列基板801的边缘位置设置有扇出结构,从而通过覆晶薄膜94与主控板93实现电连接。覆晶薄膜94包括膜片基体和设于其上的晶片942,为了进一步减少边框的宽度,在中框92背离导光板30的表面开设有容纳槽9221,将膜片基体贴于中框92的表面延伸设置,将晶片942容纳于容纳槽9221内,从而最大程度的缩小覆晶薄膜94所占用的横向宽度,进一步实现更窄边框。
具体地,组装该显示设备900的步骤包括以下:
请参照图8,首先,安装导光板30和光源20。将导光板30安装到背板10上,将中框92对应安装到弯折部32的一侧,将光源20安装到背板10的第二面12,并与弯折部32的入光端面3221相对应。该方式可以确保导光板30的安装稳定后,再针对性的安装光源20,从而提升光源20安装位置的准确性,并能合理设计光源20与导光板30的安全距离,减少损坏的几率。与此同时,在设置有反射片50和光学膜片时,先粘接反射片50,再粘接导光板30,最后安装光学膜片至导光板30上方。当还设有第一反射件40和防护层60时,在安装导光板30之前先将防护层60设于背板10上,以此能够减少对导光板30的损伤,提高防护性,然后再将第一反射件40夹设于弯折部32与中框92之间。
请参照图9,其次,安装支架91。将固定部911粘接于背板10的第二面12,遮光部912位于光源20的下方。当然,固定部911也可以通过螺纹连接固定到背板10。通过光源20的位置再确定固定部911的固定位置,能够保证遮光部912完全遮盖光源20,提升遮光效果。当有第二反射件914时,先将第二反射件914贴设于遮光部912的上表面,再安装固定部911,如此,可以提高便利性,防止因遮光部912与光源20之间的遮挡而干涉不方便安装。
请参照图10,再次,组装显示面板800至背光模组100。将阵列基板801和彩膜基板802相对压合,并将覆晶薄膜94的一端连接到阵列基板801的边缘,另一端连接到主控板93。然后将阵列基板801的边缘搭接到中框92的上表面,彩膜基板802位于阵列基板801的上方,将覆晶薄膜94沿中框92的外表面延伸贴合,最后将主控板93放置于支架91的下方,并通过粘接或焊接方式固定。该方式可以在方便放置的情况下提前完成电连接,然后再将覆晶薄膜94沿中框92贴合,从而进一步提升组装的便利性,并可以减少对其他部件的影响和空间的占用。
最后,组装前框96和后框95,显示面板800还包括有相连接的前框96和后框95,前框96包覆于显示面板800的边缘,后框95包覆主控板93、中框92及背板10的背面,从而形成稳定的安装结构,实现显示设备900的窄边框结构。
请结合图5和图7,此外,当彩膜基板802朝向导光板30的一侧设置时,阵列基板801则搭接在中框92的上表面,前框96可以不包覆阵列基板801的边缘,从而实现显示设备900的无边框结构。
以上所述仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是在本发明的发明构思下,利用本发明说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
