为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
目前，拼接屏所采用的背光源基本都采用直下式的结构设计，例如，图1为一种采用直下式背光源的显示模组的立体结构示意图，如图1所示，发光二极管灯条(LED)01放置在背板02的底部，经过30mm左右的混光距离后，发光二极管灯条01搭配扩散板和膜材之后形成所需要的面光源。但是，图1所示的结构通常容易出现显示画面周边发暗的现象。例如，图2为图1所示显示模组的边缘亮度的分布图，如图2所示，距离显示边缘20mm～120mm的区域范围内，亮度曲线呈现先下降后上升的趋势，即最终呈现下凹的趋势，从而出现显示模组的边缘区域发暗的问题。例如，显示模组的边缘发暗的现象与直下式发光二极管灯条的灯珠的光强空间角度分布特
性、光斑叠加效应以及边缘斜面的反射情况有关。
例如，图3为一种直下式单颗发光二极管灯珠发射的光线经过折射后的光路示意图，如图3所示，h为发光二极管灯珠与显示面板之间的距离；θ为发光角度；r为在发光角度为θ的条件下沿着观看视角从发光二极管灯珠到观看点之间的斜线距离；x为在平行于显示面板的主表面的方向上，在发光角度为θ的条件下，发光二极管灯珠的中心在显示面板上的正投影到沿着观看视角的观看点之间的距离，且cosθ＝h/r。
例如，图4为一种单颗发光二极管灯珠发射的光线的光强随着发光角度θ的分布的示意图，图5为一种单颗发光二极管灯珠发射的光线对应光斑的照度Ev随着平面位置x的变化的分布曲线图。例如，如图4所示，单颗发光二极管灯珠发射的光线经过棱镜折射后的发光强度Iv随着发光角度θ的增加而增加，单颗发光二极管灯珠正上方单个光斑的照度Ev可由如下公式计算得出：
Ev＝Iv*cosθ/r2
Ev＝Iv*cosθ/r2
经过计算可以得出单颗发光二极管灯珠的光斑照度随着平面位置x分布，从分布曲线上可以看出光斑在中心区域的照度较大，越远离中心区域光斑的照度逐渐减弱。将单颗发光二极管灯珠对应的光斑分布曲线按照一定间距进行排列叠加，可以得到直下式蓝光发光表面的一维照度分布，例如，图6为经过叠加之后直下式发光二极管灯珠光斑叠加的一维分布图，如图6所示，由4个发光二极管灯珠的光斑进行叠加，即由1#发光二极管灯珠、2#发光二极管灯珠、3#发光二极管灯珠和4#发光二极管灯珠的光斑进行叠加，从图6中可以看出，1#发光二极管灯珠的照度在0-100mm的位置范围内保持稳定，在100mm-300mm的位置范围内出现下降的趋势；2#发光二极管灯珠的照度在0-50mm的位置范围内出现上升的趋势，在50mm-180mm的位置范围内保持稳定，在180mm-350mm的位置范围内出现下降的趋势；3#发光二极管灯珠的照度在0-120mm的位置范围内出现上升的趋势，在120mm-220mm的位置范围内保持稳定，在220mm-410mm的位置范围内出现下降的趋势；4#发光二极管灯珠的照度在0-180mm的位置范围内出现上升的趋势，在180mm-300mm的位置范围内保持稳定，在300mm-420mm的位置范围内出现下降的趋势；4个发光二极管灯珠的照度经过叠加之后得到的照度曲线中，距离显示面板的边缘的距离越近，直下式发光二极管灯珠的
光斑的照度越弱，以最终在显示模组的边缘形成边缘发暗的区域。例如，在图6中，在经过叠加之后得到的照度曲线中，在中间区域光斑照度保持稳定趋势，在两端处曲线呈现下降趋势。且由于显示模组的边缘区域发暗，多个显示模组拼接之后形成的拼接屏的显示效果也会受到影响，且拼接屏整体的均一性较差。例如，图7为边缘亮度发暗的显示模组拼接后形成的拼接屏的显示效果图，如图7所示，在相邻的显示模组的拼缝处会出现亮度发暗的现象，从而最终使得形成的拼接屏的显示效果变差，如何消除拼接单元边缘发暗的缺陷，是拼接显示领域需要解决的问题。
本公开的发明人注意到，可以将发光二极管灯条粘贴于背板的侧面，由发光二极管发射的光线经过设置在背板的底部的导光板后形成均匀的一级面光源，然后采用大倾角中框的倾斜部分遮挡一级面光源的边缘并在导光板和显示面板之间间隔的区域中进行混光，以使得最终二级面光源的周边具有和一级面光源同等的画面显示效果，结合侧入式周边画面具有均一性的特点和直下式结构可实现超窄边框的优点，将最终形成的显示模组应用于拼接屏中可以确保拼接屏周边亮度的均一性，从而可以提升拼接屏最终的显示视觉效果，同时还可以降低最终形成的拼接屏的厚度，并节省了发光二极管的成本。将具有该种结构的显示模组应用于拼接显示屏中还可以解决边缘亮暗带的问题，而且该拼接屏的厚度比主流直下式的拼接屏的厚度薄，并且基于该结构将量子点膜放置在导光板的靠近显示面板的一侧并使得中框的倾斜部分遮挡量子点膜的边缘，并搭配蓝光发光二极管灯条，以实现高色域极窄边框拼接屏显示，还能解决量子点膜容易出现的失效蓝色发光区域进入可视区的问题。
本公开至少一实施例提供一种显示模组，该显示模组包括背光模组和显示面板，该背光模组包括：背板、光学元件、发光元件和中框，该背板包括底板和侧板，该光学元件设置在底板的靠近显示面板的一侧，该发光元件设置在侧板的靠近光学元件的一侧，该中框设置在底板与显示面板之间，且该中框包括第一条形部分，第一条形部分从靠近显示面板的位置向远离显示面板的位置延伸至光学元件的上方，第一条形部分的至少部分与光学元件的靠近显示面板的表面之间具有第一夹角，该第一夹角为锐角或者直角，该第一条形部分在显示面板上的正投影至少与光学元件的靠近发光元件的边缘在显示面板上的正投影交叠。该显示模组结合了侧入式周边画面均一性和直下
式结构可以实现超窄边框的优点，将该显示模组应用于拼接屏产品中可以确保拼接屏周边亮度的均一性，并且可以提升拼接屏进行显示的视觉效果，同时还可以减小拼接屏产品的厚度，从而可以节省发光元件的成本。
例如，图8为本公开至少一实施例提供的一种显示模组的截面结构示意图，如图8所示，该显示模组10包括背光模组100和显示面板200，该背光模组100包括：背板101、光学元件102、发光元件103和中框104，该背板101包括底板1011和侧板1012，该光学元件102设置在底板1011的靠近显示面板200的一侧，该发光元件103设置在侧板1012的靠近光学元件102的一侧，该中框104设置在底板1011与显示面板200之间，且该中框104包括第一条形部分1041，第一条形部分1041从靠近显示面板200的位置向远离显示面板200的位置延伸至光学元件102的上方，垂直于显示面板200的主表面的方向为第一方向Z，第二方向X垂直于第一方向Z，例如，该光学元件102的延伸方向平行于第二方向X或者大致平行于第二方向X，该侧板1012的延伸方向平行于第一方向Z或者大致平行于第一方向Z。第一条形部分1041的至少部分与光学元件102的靠近显示面板200的表面之间具有第一夹角β，该第一夹角β为锐角或者直角。该第一条形部分1041在显示面板200上的正投影至少与光学元件102的靠近发光元件103的边缘在显示面板200上的正投影交叠。该显示模组100结合了侧入式周边画面均一性和直下式结构可实现超窄边框的优点，将该显示模组200应用于拼接屏产品中可以确保拼接屏周边亮度的均一性，并可以提升拼接屏进行显示时的视觉效果，同时还可以减小最终形成的拼接屏产品的厚度，从而可以节省发光元件的成本。
例如，在图8所示的结构中，该中框104还包括大致平行于第一方向Z并从靠近显示面板200的位置向远离显示面板200的位置延伸的第二条形部分1042，且该第二条形部分1042在靠近显示面板200的一端与第一条形部分1041连接。该第二条形部分1042的截面形状为长条形，该第一条形部分1041的截面形状也呈长条形，该第二条形部分1042的一端和该第一条形部分1041的一端连接，以使得该第一条形部分1041相对于第二条形部分1042倾斜设置，且使得该第二条形部分1042和该第一条形部分1041之间具有第二夹角α，该第二夹角α为锐角，该第一条形部分1041的另一端延伸至光学元件102的靠近显示面板200的一侧以与光学元件102连接，本公开的实
施例不限于该第一条形部分1041的截面形状呈长条形，在其他的示例中，该第一条形部分1041的截面形状还可以呈折线型、弧线形等，本公开的实施例对此不作限定。
例如，如图8所示，该中框104的第一条形部分1041可以对光学元件102的边缘进行遮挡以改善显示面板200的周边光线均一性差的问题。需要说明的是，光学元件102的靠近发光元件103的边缘是指从光学元件102的靠近发光元件103的端部向远离发光元件103的一侧延伸的长度范围为0-180mm之内的区域，该部分区域被第一条形部分1041遮挡后，可以提高显示模组画面显示的均一性。
例如，在一个示例中，该光学元件102包括导光板1021，该导光板1021配置为接收从发光元件103发射的光线，并将该光线传导至显示面板200，且第一条形部分1041的另一端延伸至导光板1021的靠近显示面板200的一侧以与导光板1021连接，即在导光板1021的靠近显示面板200的一侧未设置其他的层结构。
例如，如图8所示，该导光板1021能够将从发光元件103发射的光线通过全反射的方式分布到光学元件102的整个面上，从而有利于提高显示模组10的发光元件103的利用率。该导光板1021还可以保证出光的均匀性，且出射的光线可以通过中框104的第一条形部分1041反射，并最终可以减小在垂直于显示面板200主表面的方向上，显示面板200与光学元件102之间的垂直距离，即可以减小出射光线混光的距离，使得最终形成的显示模组的厚度减薄。
例如，该背板101由铁板金制备而成，且该背板101的厚度为0.6mm～1.2mm。
例如，该发光元件103包括并排设置的多个LED灯，也可以是LED灯条，本公开的实施例对此不作限定。
例如，该显示面板200可以包括相对设置的阵列基板和彩膜基板，在阵列基板和彩膜基板之间设置有液晶，例如，在显示面板200中阵列基板上设置有多条栅线和多条数据线，多条栅线和多条数据线限定出多个像素单元，每个像素单元内设置有薄膜晶体管和像素电极，薄膜晶体管的栅极与栅线电连接，源极与数据线电连接，漏极与像素电极电连接；彩膜基板包括网格状的黑矩阵，以及设置于黑矩阵开口内的阵列排布的多个色阻，色阻包括红色
色阻、绿色色阻和蓝色色阻。通过像素电极和公共电极之间的电场控制液晶分子的偏转，从而达到显示效果。例如，该显示面板200包括的其他结构可以参见常规的设计，在此不再赘述。
例如，图9为本公开至少一实施例提供的再一种显示模组的截面结构示意图，图9所示的显示模组10与图8所示的显示模组10的不同之处在于该中框104包括的第一条形部分1041的截面形状呈折线型。例如，第一条形部分1041的至少部分与第一方向Z之间具有第一夹角β，该第一夹角β为锐角。该第一条形部分1041的靠近光学元件102部分与第二方向X之间具有第一夹角β，该第一夹角β为锐角，即该第一条形部分1041的靠近光学元件102部分与光学元件102的靠近显示面板200的表面之间具有该第一夹角β。该第一条形部分1041还包括大致平行于光学元件102的主表面的部分，该第一条形部分1041在显示面板200上的正投影至少与光学元件102的靠近发光元件103的边缘在显示面板200上的正投影交叠。该显示模组100结合了侧入式周边画面均一性和直下式结构可实现超窄边框的优点，将该显示模组200应用于拼接屏产品中可以确保拼接屏周边亮度的均一性，并可以提升拼接屏进行显示时的视觉效果，同时还可以减小最终形成的拼接屏产品的厚度，从而可以节省发光元件的成本。
例如，如图9所示，该中框104的第一条形部分1041可以对光学元件102的边缘进行遮挡以改善显示面板200的周边光线均一性差的问题。需要说明的是，光学元件102的靠近发光元件103的边缘是指从光学元件102的靠近发光元件103的端部向远离发光元件103一侧延伸的长度范围为0-180mm之内的区域，该部分区域被第一条形部分1041遮挡后，可以提高显示模组画面显示的均一性。
例如，图10为本公开至少一实施例提供的又一种显示模组的截面结构示意图，图10所示的显示模组10与图8所示的显示模组10的不同之处在于该中框104包括的第一条形部分1041的截面形状呈折线型。例如，第一条形部分1041的至少部分与第一方向Z之间具有的第一夹角β为直角，即该第一条形部分1041的靠近光学元件102部分与光学元件102的靠近显示面板200的表面之间具有的该第一夹角β为直角。该第一条形部分1041还包括大致平行于光学元件102的主表面的部分，该第一条形部分1041的大致平行于光学元件102的主表面的部分与第二条形部分1042之间具有的第
二夹角α为直角。该第一条形部分1041在显示面板200上的正投影至少与光学元件102的靠近发光元件103的边缘在显示面板200上的正投影交叠。该显示模组100结合了侧入式周边画面均一性和直下式结构可实现超窄边框的优点，将该显示模组200应用于拼接屏产品中可以确保拼接屏周边亮度的均一性，并可以提升拼接屏进行显示时的视觉效果，同时还可以减小最终形成的拼接屏产品的厚度，从而可以节省发光元件的成本。
例如，如图10所示，该中框104的第一条形部分1041可以对光学元件102的边缘进行遮挡以改善显示面板200的周边光线均一性差的问题。需要说明的是，光学元件的靠近发光元件的边缘是指从光学元件的靠近发光元件的端部向远离发光元件一侧延伸的长度范围为0-180mm之内的区域，该部分区域被第一条形部分1041遮挡后，可以提高显示模组画面显示的均一性。
例如，图11为本公开至少一实施例提供的一种光线经过导光板后的光路图，且图11以图8中所示的显示模组为例进行说明，该导光板1021的远离显示面板200的表面具有辅助散射结构1021a，该辅助散射结构1021a配置为将入射至导光板1021中的光线进行散射，经过散射后的光线通过中框104包括的第一条形部分1041进行反射，然后被反射后的光线直接照射至显示面板200的靠近导光板1021一侧的光学膜层201，从而使得周边的亮度提高，进而可以改善侧入式周边画面的均一性。
例如，如图11所示，该辅助散射结构1021a包括向靠近显示面板200的一侧凸起的多个凸起结构。该辅助散射结构1021a包括的多个凸起结构在导光板1021的远离显示面板200的表面呈阵列排布，且多个凸起结构均匀分布，这样可以对入射至导光板1021中的光线进行均匀地散射，从而使得出射光线的分布更加均匀，需要说明的是，该辅助散射结构1021a还可以是除了凸起结构之外的其他的结构，只要能够实现对光线进行散射即可，本公开的实施例对此不作限定。
例如，在一个示例中，该导光板1021是由聚甲基丙烯酸甲酯等透明光学材料形成的板状部件，该辅助散射结构1021a设置在导光板1021的远离显示面板200的表面。例如，该辅助散射结构1021a的立体形状呈球面状，其表面具有固定的曲率。例如，该辅助散射结构1021a可以具有其表面的曲率约为0.1mm、最大高度约为0.004mm、折射率约为1.5的球面状结构。此外，相邻的辅助散射结构1021a的中心间隔可以设置为0.075mm。需要说明
的是，该导光板1021的材料不限于聚甲基丙烯酸甲酯，该导光板1021的材料只要满足光透射率高、成型加工性优异即可，例如，该导光板1021的材料还可以使用聚碳酸酯树脂等其它树脂材料或者使用钢化玻璃材料，来替代聚甲基丙烯酸甲酯。
例如，如图11所示，发光元件103发射的光线从导光板1021的靠近发光元件103的表面入射到导光板1021的内部。该发光元件103发射的光线在导光板1021的内部传播，由于设置在导光板1021中的辅助散射结构1021a与空气层的折射率具有差值而使得该发光元件103发射的光线能够被辅助散射结构1021a全反射，然后该光线从导光板1021的靠近显示面板200的表面向显示面板200的方向出射。
例如，在一个示例中，为了使得从导光板1021的靠近显示面板200的表面出射的光线的亮度分布均匀，可以将辅助散射结构1021a设置为越远离发光元件103越密集，越靠近发光元件103越稀疏，本公开的实施例不限于此，为了使得显示模组的亮度分布成为期望的值，还可以将辅助散射结构1021a配置为在对应与显示面板的中间区域均匀分布。
例如，图12为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图12所示，该光学元件102还包括设置在导光板1021的靠近显示面板200一侧的量子点膜层1023，该第一条形部分1041延伸至量子点膜层1023的上方，并与该量子点膜层1023连接。例如，可以通过第一条形部分1041和量子点膜层1023直接接触进行连接，也可以通过粘结胶将第一条形部分1041和量子点膜层1023进行连接，只要使得该第一条形部分1041能够稳定地形成在量子点膜层1023的上方即可，不公开的实施例对此不作限定。
例如，该量子点膜层1023可以提高显示模组显示的色域。
例如，如图12所示，该光学元件102沿着第二方向X延伸，或者大致沿着第二方向X延伸，该量子点膜层1023包括在平行于显示面板200的主表面的方向上，例如，沿着第二方向X依次相邻设置的第一量子点膜层1023a、第二量子点膜层1023b和第三量子点膜层1023c，从第一量子点膜层1023a、第二量子点膜层1023b和第三量子点膜层1023c出射的光线的颜色均不相同。
例如，第一量子点膜层1023a可以将该发光元件103发射的光线转换为
不同于该光线的颜色的第一光线，第二量子点膜层1023b可以将该光线转换为不同于该光线的颜色和不同于第一光线的颜色的第二光线，第三量子点膜层1023c可以使得从该发光元件103发射的光线的颜色保持不变而使得该光线透过。
例如，在一个示例中，该第一量子点膜层1023a包括红色量子点和透光的基质，第二量子点膜层1023b包括绿色量子点透光的基质，该第三量子点膜层1023c中包括散射粒子和透光的基质。在一个示例中，该发光元件为蓝光LED，该发光元件发射的光线为蓝色光线，蓝色光线经过第一量子点膜层1023a、第二量子点膜层1023b和第三量子点膜层1023c之后，从第一量子点膜层1023a出射的光线的颜色为红色，从第二量子点膜层1023b出射的光线的颜色为绿色，从第三量子点膜层1023c出射的光线的颜色为蓝色。
例如，该基质包括透明树脂，该散射粒子的材料包括透明金属氧化物。该第三量子点膜层1023c的主要作用是对蓝色光线进行分散。
当然，本公开的实施例不限于此，还可以采用发射其他颜色光线的发光元件。
例如，图13为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图13所示，该中框104的第一条形部分1041的截面形状具有向远离侧板1012的一侧凸起的弧形结构，该弧形结构可以对入射至其上的光线进行均匀的反射。该第一条形部分1041的远离侧板1012的表面为弧线形，该第一条形部分1041的靠近侧板1012的表面为折线形，且第一条形部分1041的靠近光学元件102的部分与底板1011的主表面之间的第一夹角β为直角，也即该第一条形部分1041的靠近光学元件102部分与第二方向X之间具有第一夹角β，该第一夹角β为直角。该第一条形部分1041的至少部分与第一方向Z之间具有的第二夹角α为锐角。
例如，如图13所示，该光学元件102还包括设置在导光板1021的靠近显示面板200一侧的量子点膜层1023，该第一条形部分1041延伸至量子点膜层1023的上方，并与该量子点膜层1023连接。例如，可以通过第一条形部分1041和量子点膜层1023直接接触进行连接，也可以通过粘结胶将第一条形部分1041和量子点膜层1023进行连接，只要使得该第一条形部分1041能够稳定地形成在量子点膜层1023的上方即可，本公开的实施例对此不作限定。该量子点膜层1023的相关特征可以参见上述中的相关描述，在此不
再赘述。
例如，结合图8-图13，该第一条形部分1041的靠近光学元件102的部分与底板1011的主表面之间的夹角越大，沿着第二方向X，该第一条形部分1041与光学元件102的接触位置到光学元件102的靠近发光元件103的边缘的距离越小，该第一条形部分1041与光学元件102的接触位置到侧板1012的最靠近发光元件103的边缘的距离越小，从而可以使得显示模组周边出光的均匀性得到更大的提升。
例如，如图13所示，该发光元件103包括发光条103a和灯珠103b，该发光条103a与侧板1012的靠近光学元件102的表面通过第一粘结胶105进行连接，例如，该第一粘结胶105为光学胶，本公开的实施例对第一粘结胶105的材料不作限定，只要能够满足将发光条103a与侧板1012进行连接，且能够使得光线通过即可。
例如，图14为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图14所示，该光学元件102还包括设置在导光板1021的靠近底板1011一侧的反射结构1024，以及设置在导光板1021的远离底板1011一侧的光扩散结构1025。例如，该反射结构1024可以对入射至其上的光线进行反射。
例如，该反射结构1024配置为将从导光板1021的远离显示面板200的表面出射的光线进行反射而作为照射显示面板200的照明光再次加以利用。例如，该反射结构1024可以采用以聚对苯二甲酸乙二醇酯等树脂为基础材料的光反射片或者通过蒸镀金属材料而形成的光反射片。
例如，如图14所示，该反射结构1024和底板1011通过第二粘结胶106进行整面贴合，该反射结构1024和导光板1021通过第三粘结胶107进行整面贴合，该导光板1021和光扩散结构1025通过第四粘结胶108进行整面贴合。

例如，如图14所示，该第一条形部分1041的靠近导光板1021的表面和光扩散结构1025通过第六粘合胶109进行连接。在其他的示例中，该第
一条形部分1041的靠近导光板1021的表面和光扩散结构1025还可以直接接触。
例如，图15为本公开至少一实施例提供的又一种显示模组的截面结构示意图，如图15所示，该光学元件102还包括设置在导光板1021的靠近底板1011一侧的反射结构1024，以及设置在导光板1021和量子点膜层1023之间的光扩散结构1025，该反射结构1024和底板1011通过第二粘结胶106进行整面贴合，该反射结构1024和导光板1021通过第三粘结胶107进行整面贴合，该导光板1021和该光扩散结构1025通过第四粘结胶108进行整面贴合，该量子点膜层1023和光扩散结构1025通过第五粘结胶110进行整面贴合。
例如，本公开的实施例对第二粘结胶106、第三粘结胶107、第四粘结胶108、第五粘结胶110和第六粘合胶109的材料不作限定，该第二粘结胶106、第三粘结胶107、第四粘结胶108、第五粘结胶110和第六粘合胶109可以为双面胶或者OCA光学胶等，只要能够满足将对应的层结构进行连接，且能够使得光线通过即可。
例如，如图15所示，该第一条形部分1041的靠近导光板1021的表面和量子点膜层1023通过第六粘合胶109进行连接。在其他的示例中，该第一条形部分1041的靠近导光板1021的表面和量子点膜层1023还可以直接接触。
例如，在一个示例中，该中框104与背板1012通过卡扣固定连接，该通过卡扣固定连接的方式可以参见常规的设计，本公开的实施例对此不作限定。
例如，如图8～15所示，该显示面板200包括液晶盒201和光学膜层202，该光学膜层202设置在液晶盒201的靠近中框104的一侧，且该光学膜层202和液晶盒201通过第七粘合胶111粘结。
例如，如图15所示，在一个示例中，该光学膜层202还可以包括层叠设置的增光膜2021和扩散膜2022，且该扩散膜2022设置在增光膜2021的靠近液晶盒201的一侧。
例如，在另一个示例中，该扩散膜2022可以包括第一扩散膜和第二扩散膜层叠设置形成的双层结构，该增光膜2021夹置在双层结构的第一扩散膜和第二扩散膜层之间。
例如，当扩散膜2022为单层结构时，该扩散膜2022包括扩散层、基材和保护层；当该扩散膜2022包括第一扩散膜和第二扩散膜层叠设置形成的双层结构时，该第一扩散膜和第二扩散膜分别包括扩散层、基材和保护层。例如，基材采用光透过率高的聚对苯二甲酸乙二醇酯(PET)或者聚碳酸酯(PC)等材料形成，扩散层和保护层采用亚克力树脂形成。
例如，该扩散膜2022可以使得入射至其上的光线产生漫反射，使得光线均匀分布，以保证显示模组显示亮度的均匀性。
例如，该增光膜2021可以从整体上保证显示模组亮度的均一性。
例如，经过扩散膜2022和增光膜2021反射的光线在光学膜层202和导光板1021之间进行混光，光线最终从光学膜层202的上表面出射，以为显示面板200提供面光源。
例如，该光学膜层202还可以包括上棱镜和下棱镜，以提高显示模组的正式亮度或者轴向亮度，该上棱镜和下棱镜可以参见常规的设计，本公开的实施例对此不作限定。
