本发明的实施方式
以下各实施例的说明是参考附加的图示,用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语,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申请,而非用以限制本申请。在图中,结构相似的单元是用以相同标号表示。
如图1以及图2所示,现有的背光模组10包括背框101、导光板102、侧光源103(包括电路板1031和LED灯1032),显示装置包括背光模组10及显示面板20,所述显示面板20包括阵列基板201、与所述阵列基板201相对设置的彩膜基板202、设置在阵列基板201上的驱动芯片203、以及绑定在所述阵列基板201上的柔性电路板204,其中,所述阵列基板201包括显示区211以及与所述显示区211相邻的非显示区212。所述显示装置的下边框高度d为所述显示区211的下边缘至所述显示装置的下边缘的距离,即所述显示区211与所述背光模组10的可视区(一般与彩膜基板202的边缘对齐)之间的距离a、所述背光模组10的可视区与所述背光模组10的下边缘之间的距离b及所述背光模组10的下边缘与所述显示装置的下边缘(一般与柔性电路板204的边缘等同)之间的距离c的和,即d=a+b+c。
在现有技术中,所述显示装置主要是通过增加所述侧光源103的排布密度以减小混光距离来使得其下边框变窄,即通过减小所述背光模组10的可视区与所述背光模组10的边缘之间的距离b的值,以提高屏占比,但是随着下边框越来越窄,所述侧光源103排布的空间有限,导致所述侧光源103的排布密度无法增加,因此无法通过增加所述侧光源103的排布密度来使得所述显示装置的下边框d尺寸变小,继而无法提高屏占比。
本申请针对现有技术的背光模组及显示装置,随着下边框越来越窄,光源组的排布空间有限,导致光源组的排布密度无法增加,因此无法通过增加光源组的排布密度来使得显示屏的下边框变得更窄的技术问题,本申请实施例可以缓解。
在一种实施例中,如图3所示,本申请提供的背光模组30包括:
背框301,背框301包括至少一个用于限位的多个限位侧边3011、以及至少一个用于放置侧光源的光源侧边3012,这些光源侧边3012和限位侧边3011合围形成容纳腔;
导光板302,设置在容纳腔内,所述导光板302入光面与所述光源侧边3012对应;
侧光源303,包括电路板3031和LED灯等光源3032,设置在所述背框301的光源侧边3012与导光板302之间,即位于容纳腔内;所述背框301的光源侧边3012对应所述导光板302的入光面,光源3032的发光方向朝向所述导光板302的入光面;
其中,所述背框301的光源侧边3012形成有至少两个背光凹陷部304。
在一种实施例中,背框301包括胶框和胶铁一体框等多种实现方式。
在一种实施例中,当背框301通过胶铁一体框的方式实现时,该胶铁一体框包括底板以及合围的侧边,底板和侧边形成容纳腔,此时需要将光源侧边3012形成至少两个背光凹陷部304的同时,需要对底板对应背光凹陷部304的位置进行处理形成凹槽,才可实现本申请,在该实施例中,背光模组是独立于显示装置的其他功能单元的,反射片先放置在容纳腔内的底板上,然后导光板放置在反射片上、且位于容纳腔内。
在一种实施例中,当背框301通过胶框的方式实现时,该胶框仅包括合围的侧边以形成容纳腔,而没有底板,此时仅需要将光源侧边3012形成至少两个背光凹陷部304即可实现本申请,在该实施例中,背光模组的胶框是固定在显示装置的其他功能单元上,反射片先放置在容纳腔内,然后导光板放置在反射片上、且位于容纳腔内。
在一种实施例中,如图3所示,背光凹陷部304的形状为矩形或者U形,可以根据工艺条件或者显示装置设置需求确定。
在一种实施例中,背光凹陷部304的宽度为所述底板宽度的1%~50%,一方面,所述背光凹陷部304的宽度需满足柔性电路板能够穿过所述述背光凹陷部304进行弯折,另一方面能够为光源放置区放置侧光源留有足够的空间,使得所述背光模组能够为显示面板提供足够强的光线。
在一种实施例中,所述至少两个背光凹陷部304将所述背框的光源侧边分割成至少三个凸出部305,所述侧光源303包括位于所述凸出部内和/或凸出部之上的光源组。
在一种实施例中,所述侧光源303位于所述凸出部305内,此时,凸出部305形成光源放置区。
在一种实施例中,如图4所示,侧光源303包括位于光源放置区内的光源组,所述光源组包括第一光源组3031、第二光源组3032、第三光源组3033,第一光源组3031、第二光源组3032、第三光源组3033通过同一个电路板进行驱动,以便于统一驱动发光。
在一种实施例中,第一光源组3031、第二光源组3032、第三光源组3033可以通过三个电路板分别进行驱动发光,节省电能。
在一种实施例中,如图4所示,所述导光板302的形状为矩形,所述第一光源组3031与所述第三光源组3033分别设置于所述导光板302的两侧,第二光源组3032分别设置于所述导光板302的中间位置,并分别与导光板302的入光面的部分区域相对设置,第一光源组3031、第二光源组3032、第三光源组3033发出的光线射入该区域。
在一种实施例中,如图5所示,所述导光板302在靠近所述背光凹陷部的边缘(即入光面)设置有凸部3021,所述凸部3021的设置位置与所述背光凹陷部304对应,凸部3021可以不具备入光面的光学特性,仅用于将导光板固定在底板内。
在一种实施例中,如图5所示,凸部3021包括边缘以及与所述边缘两端连接的第一倾斜面和第二倾斜面,所述第一倾斜面与所述导光板入光面之间形成的第一夹角a为非锐角,所述第二倾斜面与所述导光板入光面之间形成的第二夹角b为非锐角。所述第一夹角a的大小为90°~135°,所述第二夹角b为90°~135°,以使所述第一光源组3031、第二光源组3032、第三光源组3033发出的光线射入至所述凸部3021内,进而使得所述第一光源组3031、第二光源组3032、第三光源组3033射入至所述导光板32的光线分布均匀,以获得更好的光学品味。
在一种实施例中,所述第一夹角与所述第二夹角的大小可相同,也可不同。
在一种实施例中,所述凸部3021的边缘为直线形或圆弧形,可以根据需要设置。
导光板主要采用光学级的亚克力板材等,用具有极高反射率且不吸光的高科技材料,在亚克力板材的底面上使用激光雕刻等印刷技术印出多个导光点,该导光点又称为网点。采用亚克力板材的时候,主要是利用光学级亚克力板材吸取从灯发出来的光在光学级亚克力板材表面的停留,当光线射到各个网点时,反射光会往各个角度扩散,然后由导光板的正面射出。
因背光模组存在背光凹陷部等凹形结构,对应的,背光凹陷部的LED等侧光源的间距相对其他位置更大,故该区域的入光会比较少。因此,在一种实施例中,如图6所示,所述导光板302的下表面上设置有网点3022,所述凸部3021对应区域3023(包括凸部321的前方区域和中间区域)内的网点3022密度大于其他区域,可以提升凸部3021对应区域3023的亮度,优化均匀性。
在一种实施例中,所述凸部3021对应区域3023内的网点深度大于其他区域,可以进一步的提升凸部3021对应区域3023的亮度,优化均匀性。
在一种实施例中,如图7所示,所述光源组303包括多个沿电路板3031(例如柔性印刷电路板等)长度方向均匀间隔设置的LED灯3032,所述电路板3031分为垂直段与倾斜段,所述垂直段与导光板302除去凸部3021的区域,倾斜段与所述凸部3021的第一倾斜面和第二倾斜面相对,各光源组的LED灯的数量依据其对应的平面宽度而定。
在一种实施例中,如图7所示,所述光源组靠近所述背光凹陷部区域(即位于背板倾斜段)内的光源的出光方向,与所述导光板入光面之间形成的第三夹角c为锐角。
在一种实施例中,所述第三夹角为0°~45°,可以便获得更好的光学品味。
在一种实施例中,所述背光模组还包括:设置于所述导光板出光面一侧的光学膜片,例如扩散片等;设置于所述导光板背离出光面一侧的反射片等,在此不再一一详细描述。
在一种实施例中,同时,如图8以及图9所示,本申请提供了一种显示装置,其包含本申请提供的背光模组30,以及显示面板40。
显示面板40包括阵列基板401、以及与所述阵列基板401相对设置的彩膜基板402;所述阵列基板401表面定义有显示区403,所述显示区403通过框胶限定,所述框胶内设置有液晶层,所述彩膜基板402与所述阵列基板401通过所述框胶相结合。
所述显示区403外与所述阵列基板401边缘之间的区域形成非显示区404,所述非显示区404内布设有信号走线、以及绑定有驱动芯片405、柔性电路板406等其它电子元件。
所述彩膜基板402短于所述阵列基板401,且所述彩膜基板402高于所述阵列基板401表面,所述彩膜基板402下侧边缘在所述阵列基板401表面的投影与所述阵列基板401边缘之间的区域形成台阶区域,所述台阶区域位于所述非显示区404内,且所述驱动芯片405、所述柔性电路板406等其他电子元件位于所述非显示区404的一侧,即台阶区域内,所述信号走线从所述台阶区域延伸至整个所述非显示区404及所述显示区403内。
在切割显示面板母版时,在所述阵列基板401远离所述显示区403的一端预留至少两个凸块407,相邻凸块407之间形成面板凹陷部408,面板凹陷部408与所述背光模组的背光凹陷部304对应设置。
所述柔性电路板406包括连接于所述非显示区404内的连接区段、弯折至所述显示面板背部的主体区段、以及连接所述连接区段与所述主体区段的弯折区段,所述柔性电路板的部分区段(即弯折区段)经所述面板凹陷部408和背光凹陷部304的边缘弯折至所述背光模组30的背部。
在一种实施例中,所述凸块407包括至少一个第一凸块407a、以及至少一个第二凸块407b,第一凸块407a位于所述阵列基板401端部的中间位置,所述驱动芯片405设置于所述第一凸块407a的下侧边缘,即非显示区404边缘与所述显示区403边缘之间,从而抬升了所述驱动芯片405上侧距离所述显示区403边缘的高度,以及所述驱动芯片405下侧距离所述非显示区404边缘的高度。
在一种实施例中,所述柔性电路板的部分区段(即弯折区段)经所述第一凸块407a至少一侧的面板凹陷部408和背光凹陷部304的边缘弯折至所述背光模组30的背部。
在一种实施例中,为了进一步优化效果,所述柔性电路板弯折顶点位于所述面板凹陷部408和背光凹陷部304内。即所述弯折区段位于凹陷区域内,所述弯折区段的弯折半径小于或等于所述第一凸块407a的高度,即弯折区段没有超出面板凹陷部408。
在本申请实施例中,所述第一凸块407a根据驱动芯片的数量设置,且所述第一凸块407a和所述驱动芯片的位置不局限于所述非显示区的中间位置,例如,所述第一凸块407a还可以靠近所述非显示区的任意一侧设置。
在本申请实施例中,所述第二凸块407b根据所述第一凸块407a的数量设置,用于增大凸块407与显示装置壳体的接触面积,使得显示面板的受力均匀。第二凸块407b和第一凸块407a不局限于交错设置的方式。
在本申请实施例中,第二凸块407b可以仅具备支撑作用,其区域内不设置电路元件,也可以作为电路元件的设置区,电路元件可以是显示面板所需要的电路元件,例如转换端子等,也可以是指纹识别、摄像头等其他非显示面板所需要的电路元件。
因此,相较于现有技术的显示面板,本申请实施例扩宽了所述驱动芯片405上下两侧的空间,同时也没有增加非显示区404整体高度,不仅解决了驱动芯片405周围的空间问题,还保持了现有技术的显示面板的窄非显示区。
与图2对应的,如图10所示,所述显示装置的下非显示区高度d为所述显示区403至所述显示装置的下边缘的距离,即所述显示区403与所述背光模组30的可视区之间的距离a、所述背光模组30的可视区与所述背光模组30的下边缘之间的距离b及所述背光模组30的下边缘3与所述显示装置的下边缘之间的距离c的和,即d=a+b+c,此时所述柔性电路板406的弯折顶点位于所述面板面板凹陷部和背光面板凹陷部外。
在一种实施例中,所述柔性电路板406的弯折顶点位于所述面板凹陷部408和背光凹陷部304内,因此所述背光模组30的边缘与所述显示装置的边缘之间的距离c的值相比于传统技术的显示装置中的c值可减小(c值可为0),此时,显示装置的下非显示区高度d为所述显示区403至所述显示装置的下边缘的距离,即所述显示区403与所述背光模组30的可视区之间的距离a、所述背光模组30的可视区与所述背光模组30的下边缘之间的距离b的和,即d=a+b,从而使得本申请实施例中的所述显示装置的下非显示区尺寸相对于传统技术中的显示装置下非显示区减小,从而进一步实现窄非显示区与高屏占比。
面板凹陷部408与所述背光模组的背光凹陷部304对应设置,一般地,所述背光凹陷部304在所述背光模组30上的正投影覆盖所述面板凹陷部408在所述背光模组30上的正投影,以保护所述显示面板40。所述背光凹陷部304与所述面板凹陷部408的形状相同,也可以不同。
在一种实施例中,所述背光凹陷部304与所述面板凹陷部408的形状均为梯形,可使得所述光源放置区放置的侧光源的密度更大,增强所述显示装置的显示效果。
在一种实施例中,为了预留足够的空间布设GOA走线、扇出走线以及端子,所述驱动芯片靠近所述显示区的一侧与所述显示区边缘之间的距离,设置为大于所述驱动芯片靠近所述第一凸块的一侧与所述第一凸块边缘之间的距离。
例如,所述驱动芯片设置于所述非显示区内,且位于所述第一凸块之外。
又如,所述驱动芯片完全或部分设置于所述第一凸块内。
在一种实施例中,凸块407的形状可以是多种多样的。
在一种实施例中,如图11所示,本申请提供的显示面板包括阵列基板401、彩膜基板402、显示区403、以及形成于所述阵列基板401端部的凸块407,所述阵列基板401的非显示区404内设置有驱动芯片405。
所述凸块407包括连接所述非显示区404边缘的两条对称设置的短边,以及连接两条所述侧边另一端的长边;例如,如图11所示,所述短边为直边,且所述短边与所述非显示区404边缘之间相互垂直,此时,所述凸块407的表面形状为矩形。
在一种实施例中,所述凸块407包括连接所述非显示区404边缘的两条对称设置的短边,以及连接两条所述侧边另一端的长边;如图12所示,本申请提供的显示面板与图11的区别为:所述短边为直边,且所述短边与所述非显示区404边缘之间形成的夹角为非直角,即所述夹角大于或小于90度,所述凸块407的表面形状为梯形。
在一种实施例中,如图13所示,本申请提供的显示面板与图11、图12的区别为:所述凸块407包括一外圆弧边,所述外圆弧边的两端连接于所述非显示区404边缘,且所述外圆弧边的端部呈内圆弧过渡。
现针对柔性电路板的端子设置方式进行说明。
如图14所示,本申请提供的显示面板包括阵列基板401、彩膜基板402、以及位于所述阵列基板401的非显示区的非显示区404、设置于所述非显示区404内的驱动芯片405以及连接所述驱动芯片405的扇出走线1401,例如,所述扇出走线1401用于传输显示数据信号至所述显示区403内;所述非显示区404内设置有至少一组GOA(栅极驱动电路)走线1402,以两组相对称的GOA走线1402为例进行说明,两组所述GOA走线1402均包括位于所述显示区403外侧且平行于所述显示区403边缘的平行段,以及位于所述非显示区404内且指向所述驱动芯片405的倾斜段,所述GOA走线1402的倾斜段连接所述驱动芯片405以输入Gate信号,所述GOA走线1402的平行段连接各像素行的扫描线以输出Gate信号。
所述非显示区404内设置有多个用以连接所述柔性电路板的信号端子组,所述信号端子组至少包括主信号端子组1403和次信号端子组1404,例如,所述主信号端子组1403包括像素数据信号和栅极信号,所述次信号端子组1404包括电源信号等;其中,主信号端子组1403位于次信号端子组1404和驱动芯片405之间,以降低信号传输的延迟。
在一种实施例中,如图14所示,所述主信号端子组1403靠近所述驱动芯片405设置,所述次信号端子组1404远离所述驱动芯片405和所述GOA走线1402的倾斜段设置。由于驱动芯片405相对下移,连接所述驱动芯片405的所述GOA走线1402的倾斜段同时下移,从而压缩了端子的设置空间,端子距离所述GOA走线1402过近则会增加阻抗,会导致信号失真,影响显示品质,因此,本申请实施例将端子至少部分远离所述GOA走线1402设置。
在一种实施例中,所述次信号端子组1404与所述主信号端子组1403之间分离设置,且所述主信号端子完全或部分位于所述第一凸块407a内,所述次信号端子位于所述凸块407之外,从而有效控制端子与所述GOA走线1402的距离,降低阻抗。
如图15所示,所述柔性电路板包括主体区段4061,以及用于连接所述信号端子组的连接区段,所述连接区段包括对应连接所述主信号端子组1403的第一区块4062、以及对应连接所述次信号端子组1404的第二区块4063,所述第一区块4062与所述第二区块4063错位设置。
如图16所示,与图14的信号端子排布方式相比,各端子紧密排列,所述主信号端子组1403与所述次信号端子组1404均设置于第一凸块407a之外,从而避免对第一凸块407a的空间压缩,且所述主信号端子组1403中的各个端子的面积,与所述次信号端子组1404的各个端子的面积相当,以保证信号接触点的稳定连接。
在一种实施例中,所述主信号端子组的各端子的高度,小于所述次信号端子组的各端子的高度,并且,所述主信号端子组的各端子的宽度,大于所述次信号端子组的各端子的宽度,通过降低靠近所述GOA走线1402的端子的高度来保持与所述GOA走线1402间的距离,从而降低端子与GOA走线1402之间产生的阻抗。
在一种实施例中,所述主信号端子组1403中的各端子的高度,自远离所述驱动芯片405和所述GOA走线1402的倾斜段的端子,至靠近所述驱动芯片405和所述GOA走线1402的倾斜段的端子递减;并且,所述主信号端子组1404中的各端子的宽度,自远离所述驱动芯片405和所述GOA走线1402的倾斜段的端子,至靠近所述驱动芯片405和所述GOA走线1402的倾斜段的端子递增,从而保证各端子与GOA走线1402间的距离相等。
如图17所示,所述柔性电路板包括主体区段4061,以及用于连接所述端子的连接区段4064,所述连接区段4064的端部为规则几何形状,所述连接区段4064的端部设置有第一连接区域和第二连接区域,所述第一连接区域覆盖且连接所述主信号端子组,所述第二连接区域覆盖且连接所述次信号端子组。
在一种实施例中,所述非显示区405内还设置有虚拟端子组,所述虚拟端子组位于所述次信号端子组远离所述驱动芯片和所述GOA走线的倾斜段的一侧。虚拟端子组可以对柔性电路板进行支撑,保证显示面板的平整。
现针对第二凸块上的电路设置进行说明。
在一种实施例中,如图18所示,本申请提供的显示面板包括阵列基板401、彩膜基板402、以及位于所述阵列基板401的非显示区的非显示区404、设置于所述非显示区404内的测试端子组1405、转换端子组1406和识别端子组1406,所述测试端子组1405、转换端子组1406和识别端子组1407中的至少一种位于所述第二凸块407b的边缘与所述显示区403的边缘之间。
测试端子组1405、转换端子组1406和识别端子组1407中的端子可以同行设置于第二凸块407b的边缘与所述显示区403的边缘之间,也可以分多行设置于第二凸块407b的边缘与所述显示区403的边缘之间。
在一种实施例中,为了增大测试端子组1405、转换端子组1406和识别端子组1406之间的缝隙,如图19所示,在本申请实施例提供的显示面板中,所述测试端子组1405、转换端子组1406和识别端子组1407设置在至少两行。
测试端子组1405中的端子用于阵列基板在制备成显示面板后,通过对测试端子组1405中的端子输入测试信号以对显示面板进行性能测试。转换端子组1406中的端子用于涂布导电银胶,导电银胶用于连接阵列基板非显示区401中的接地线(未示出)和显示面板中与阵列基板对置的彩膜基板中的导电层以起到防静电作用。识别端子组1407中的端子用于记录阵列基板的相关信息,以及用于对位等。
根据上述实施例可知:
本申请提供一种背光模组及显示装置,通过在背光模组背框的光源侧边设置背光凹陷部,该背光凹陷部与显示面板上的面板凹陷部相对应,在组装时,柔性电路板的部分区段经所述面板凹陷部和背光凹陷部的边缘弯折至背光模组的背部,降低了显示装置的下边框的尺寸,提高了显示装置的屏占比,增强了产品的差异化性能,提升了产品的市场竞争力。
综上所述,虽然本申请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申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
