Description

技术领域
本申请涉及显示技术领域，尤其涉及一种拼接屏及显示装置。
 背景技术
随着显示技术的大量普及，对大尺寸显示屏的需求也在不断增长。目前，单个显示屏的尺寸很难超过80英寸，因此，拼接屏成为实现大尺寸显示的可行之路。
拼接屏是通过将较小尺寸的显示屏以阵列安装的模式拼接成较大尺寸显示屏，因此可以根据实际需求选择一定数量的显示屏来拼接成不同尺寸的大屏幕，以满足不同的应用场景。拼接屏会在两个显示屏的拼接处形成一条拼接缝，并且拼接缝的宽度是两个显示屏边框宽度之和；受限于显示屏的自身结构的特点，显示屏的边框不具有显示功能，因此，拼接屏显示的完整画面会被拼接缝割裂，并且拼接缝的宽度越大，对显示画面的割裂效果越明显，拼接屏的显示质量也越差。

请参阅图1，图1 是本申请实施例提供的显示屏的结构示意图。所述显示屏包括背光模组10、显示模组20和外框，所述外框包括第一边框301和与所述第一边框301相对的第二边框302。所述背光模组10用于提供背光源，以保证所述显示模组20正常显示；所述显示模组20对应于所述背光模组10的出光面设置，用于发挥显示功能；所述外框固定于所述显示屏的出光面和侧面，用于对所述背光模组10和所述显示模组20进行固定和保护。
所述背光模组10包括背框101、发光元件102和光学模组103。所述背框101是由底板和侧板组成的带有开口的框形结构，用于容纳所述背光模组10中的多种功能元件。所述背框101的侧板至少沿所述第一边框301和所述第二边框302设置，所述发光元件102和所述光学模组103设置于由所述侧板和所述底板围成的所述背框101的框体内。所述背框101为所述背光模组10中的各功能元件提供支撑和保护。
所述发光元件102靠近所述第一边框301设置。具体地，所述发光元件102设置于所述背框101的框体内，且沿所述背框101的靠近所述第一边框301的侧板设置，所述发光元件102可以通过导热胶固定于所述背框101的侧板上，所述导热胶用于将所述发光元件102产生的热量传导至所述背框101上并散发，防止所述发光元件102因温度过高而损坏。可选地，所述发光元件102可以是由多个发光二极管组成的LED灯条，所述LED灯条发出的光线沿平行于所述背框101的底板的方向射入所述光学模组103中，以保证所述光学模组103对光能的最大利用率。在本实施例中，通过将所述发光元件102靠近所述第一边框301设置，使得所述发光元件102占据的空间集中在所述第一边框301附近，为所述显示屏的第二边框302具有较小的宽度创造条件。
所述光学模组103设置于所述背框101的框体内，且与所述发光元件102保持平齐。所述光学模组103用于将所述发光元件102发出的平行光线，经过传导、折射、反射等过程形成均匀分布于所述光学模组103内部的多向光，并通过所述光学模组103的出光面均匀射出，所述光学模组103的出光面朝向所述显示模组20，从而为所述显示模组20提供面光源。可选地，所述光学模组103包括导光板、扩散板、棱镜片和增亮膜，所述导光板用于将所述发光元件102发射的光线传导至所述扩散板，所述扩散板、所述棱镜片和所述增亮膜用于将所述导光板传导的光线进行多次折射、反射以及散射，并最终将光线聚集在预设范围内射出，同时提升所述背光模组10的出光亮度。
所述显示模组20包括显示面板201和电性连接所述显示面板201的覆晶薄膜202。所述显示面板201用于实现所述显示屏的显示功能。可选地，所述显示面板201具有显示区AA和非显示区NA，所述显示区AA是所述显示面板201中可以显示画面的区域；所述非显示区NA可以设置于所述显示区AA的侧边，其内布置有连接所述显示区AA的多种走线和功能元件。进一步地，所述显示面板201可以是液晶显示面板，其包括相对设置的薄膜晶体管阵列基板和彩膜基板以及设置于所述薄膜晶体管阵列基板和彩膜基板之间的液晶层；所述液晶层内设置有液晶，所述薄膜晶体管阵列基板用于提供电场作用，所述液晶在电场作用下产生不同角度的偏转，进而改变光线穿过所述液晶层的路径，然后结合所述彩膜基板对光线的彩色滤光作用，使所述显示面板201呈现出彩色画面；应当理解的是，液晶显示面板是被动发光型显示面板，其需要背光模组提供背光源才能显示画面。
所述覆晶薄膜202与所述显示面板201电性连接，所述覆晶薄膜202可以包括多种控制芯片和控制电路，用于对所述显示面板201的显示功能进行控制。应当理解的是，所述显示面板201的显示区AA内包括多个显示单元，每一个显示单元均通过控制走线电性连接至所述覆晶薄膜202，因此，所述覆晶薄膜202上集成了大量的控制走线、控制电路和控制芯片，需要占据较大的边框区域，导致显示屏中设置有覆晶薄膜的一侧的边框宽度明显大于其余未设置覆晶薄膜的边框宽度。
在一种实施例中，所述覆晶薄膜202靠近所述第一边框301设置。具体地，所述覆晶薄膜202设置于所述显示屏的靠近所述第一边框301的一侧。在本实施例中，通过将所述覆晶薄膜202靠近所述第一边框301设置，使得所述覆晶薄膜202占据的空间集中在所述第一边框301附近，为所述显示屏的第二边框302具有较小的宽度创造条件 。
在一种实施例中，所述发光元件102和所述覆晶薄膜202均设置于所述显示屏的同一侧。具体为，所述发光元件102和所述覆晶薄膜202均沿所述第一边框301设置，从而使所述发光元件102和所述覆晶薄膜202占据的边框区域集中在所述第一边框301处，有利于缩减所述第二边框302的边框宽度，实现所述显示屏至少一侧的窄边框设计。应当理解的是，采用本实施例提供的显示屏制作拼接屏时，通过将所述第一边框301作为拼接边，有利于缩减所述拼接屏的拼接缝宽度，提升拼接屏的视觉美观度。
所述外框固定于所述显示屏的出光面和侧面，用于对所述背光模组10和所述显示模组20进行固定和保护。所述外框具有对应所述显示面板201的显示区AA设置的开口，用于将所述显示面板201的显示区AA暴露出来，以保证所述显示屏正常显示画面。
在一种实施例中，所述外框包括第一边框301和第二边框302，所述第一边框301向所述显示屏的中心区域延伸的宽度为所述第一边框301的宽度B1，所述第二边框302向所述显示屏的中心区域延伸的宽度为所述第二边框302的宽度B2，所述第一边框301的宽度B1大于所述第二边框302的宽度B2，例如，所述第一边框301的宽度B1为8毫米，所述第二边框302的宽度B2为2毫米。需要说明的是，所述第一边框301的宽度B1和所述第二边框302的宽度B2分别代表了所述显示屏的相对两侧的边框宽度；在本申请实施例中，所述显示屏的相对两侧的边框宽度不等，所述第二边框302的宽度B2小于所述第一边框301的宽度B1，使用所述显示屏制作拼接屏时，通过将所述第二边框302作为拼接边，可以实现拼接屏具有较小的拼接缝宽度，提升拼接屏的显示效果。
在一种实施例中，所述第一边框301的宽度B1是所述第二边框302的宽度B2的2倍，例如，所述第一边框301的宽度B1为8毫米，所述第二边框302的宽度B2为4毫米。在本实施例中，将两个所述显示屏拼接成拼接屏时，通过将两个所述显示屏的所述第二边框302均作为拼接边，使得最终形成的拼接屏的拼接缝宽度与所述第一边框301的宽度B1相等，例如，当两个所述显示屏的所述第一边框301的宽度B1均为8毫米，所述第二边框302的宽度B2均为4毫米时，将这两个所述显示屏沿所述第二边框302进行拼接，形成的拼接屏的拼接缝的宽度为8毫米，与所述第一边框301的宽度B1相等，从而使拼接屏呈现出较为规整的外观，提升拼接屏的视觉美观度。
在一种实施例中，以所述显示面板201的出光面所在的平面为参考面S，所述第一边框301在所述参考面S上的正投影覆盖所述发光元件102在所述参考面S上的正投影，并且所述第一边框301在所述参考面S上的正投影覆盖所述覆晶薄膜202在所述参考面S上的正投影。应当理解的是，基于所述发光元件102和所述覆晶薄膜202均沿所述第一边框301设置，通过设置具有一定宽度的所述第一边框301，可以实现对所述发光元件102和所述覆晶薄膜202的同时遮挡。本实施例的设计可以实现所述第一边框301对所述发光元件102和所述覆晶薄膜202的同时遮挡。
进一步地，所述显示面板201包括显示区AA和非显示区NA，所述外框在所述显示面板201上的正投影覆盖所述非显示区NA；所述外框上设置有开口，所述外框的开口在所述显示面板201上的正投影覆盖所述显示区AA。本实施例的上述设计，在保证所述外框对所述显示面板201的固定和保护作用的同时，防止所述外框遮挡所述显示面板201的出光。
本申请实施例提供一种拼接屏，所述拼接屏包括相互拼接的至少两个图1所示的实施例提供的显示屏，且相邻两个所述显示屏的至少其中之一沿所述第二边框拼接。基于图1所示的实施例，通过优化覆晶薄膜和发光元件在所述显示屏中的位置，使所述显示屏的第一边框的宽度大于所述显示屏的第二边框的宽度，使用所述显示屏制作拼接屏时，以第二边框作为拼接边，使形成拼接屏具有较小的拼接缝，提升了拼接屏的显示品质和美观度。

需要说明的是，本实施例提供的拼接屏虽然包括两个显示屏，但不仅限于此，还可以按本实施例提供的拼接方式，沿同一方向，对更多的所述显示屏进行拼接，以形成尺寸更大的拼接屏。
在一种实施例中，请参阅图1和图3所示，其中，图3是本申请实施例提供的第二种拼接屏的结构示意图。所述拼接屏包括第一显示屏01、第二显示屏02和第三显示屏03；所述第一显示屏01、所述第二显示屏02和所述第三显示屏03均是图1所示的显示屏。所述第一显示屏01、所述第二显示屏02和所述第三显示屏03的结构特征请参照上述实施例，此处不再详述。
所述第一显示屏01、所述第二显示屏02和所述第三显示屏03依次通过边缘水平拼接的方式形成所述拼接屏。具体地，所述第一显示屏01的外框包括第一边框301和与所述第一边框相对的第二边框302；所述第一显示屏01的第一边框301的宽度B1大于所述第一显示屏01的第二边框302的宽度B2。所述第二显示屏02的外框包括第一边框301和与所述第一边框301相对的第二边框302；所述第二显示屏02的第一边框301的宽度B1大于所述第二显示屏02的第二边框302的宽度B2。所述第三显示屏03的外框包括第一边框301和与所述第一边框301相对的第二边框302；所述第三显示屏03的第一边框301的宽度B1大于所述第三显示屏03的第二边框302的宽度B2。
所述第一显示屏01的第二边框302与所述第二显示屏02的第一边框301水平拼接。具体为，所述第一显示屏01的第二边框302的侧面与所述第二显示屏02的第一边框301的侧面水平对齐并拼接固定，同时保持所述第一显示屏01的显示面板201的出光面与所述第二显示屏02的显示面板201的出光面处于同一水平面上。可选地，将所述第一显示屏01的第二边框302的侧面与所述第二显示屏02的第一边框301的侧面进行拼接固定的方式可以是粘接、焊接或铆接。
所述第二显示屏02的第二边框302与所述第三显示屏03的第一边框301水平拼接。具体为，所述第二显示屏02的第二边框302的侧面与所述第三显示屏03的第一边框301的侧面水平对齐并拼接固定，同时保持所述第二显示屏02的显示面板201的出光面与所述第三显示屏03的显示面板201的出光面处于同一水平面上。可选地，将所述第二显示屏02的第二边框302的侧面与所述第三显示屏03的第一边框301的侧面进行拼接固定的方式可以是粘接、焊接或铆接。
在本实施例中，通过将具有较小边框宽度的所述第一显示屏01的第二边框302以及所述第二显示屏02的第二边框302作为拼接边，有利于减小拼接屏中拼接缝的宽度；并且所述第一显示屏01、所述第二显示屏02和所述第三显示屏03均采用本申请上述实施例提供的显示屏，使制作所述拼接屏的各个显示屏保持统一性，有利于简化拼接屏的制作工艺，提高生产效率。
可选地，按照本实施例提供的方式对所述第一显示屏01、所述第二显示屏02和所述第三显示屏03进行第一排拼接形成第一排拼接屏后，还可以按照本实施提供的方式在所述第一排拼接屏的一侧形成第二排拼接屏，并将所述第一排拼接屏与所述第二排拼接屏对位拼接，形成完整的拼接屏，从而进一步增大拼接屏的纵向尺寸。
在一种实施例中，请参阅图1和图4，其中图4是本申请实施例提供的第三种拼接屏的结构示意图。在本实施例中，所述拼接屏包括第一显示屏01和第二显示屏02，所述第一显示屏01和所述第二显示屏02均是图1所示的显示屏。所述第一显示屏01和所述第二显示屏02的结构特征请参照上述实施例，此处不再详述。
所述第一显示屏01的外框包括第一边框301和与所述第一边框301相对的第二边框302；所述第一显示屏01的第一边框301的宽度B1大于所述第一显示屏01的第二边框302的宽度B2。所述第二显示屏02的外框包括第一边框301和与所述第一边框301相对的第二边框302；所述第二显示屏02的第一边框301的宽度B1大于所述第二显示屏02的第二边框302的宽度B2。
所述第一显示屏01与所述第二显示屏02通过边缘水平拼接的方式形成所述拼接屏。具体为，所述第一显示屏01的第二边框302与所述第二显示屏02的第二边框302水平拼接同时保持所述第一显示屏01的显示面板201的出光面与所述第二显示屏02的显示面板201的出光面处于同一水平面上。可选地，将所述第一显示屏01与所述第二显示屏02拼接固定的方式可以是粘接、焊接或铆接。本实施例将具有较小边框宽度的第一显示屏01的第二边框302和第二显示屏02的第二边框302作为拼接边，使形成的拼接屏的拼接缝宽度达到最小化，有利于提升拼接屏的显示品质；并且所述第一显示屏01和所述第二显示屏02均采用本申请上述实施例提供的显示屏，使制作所述拼接屏的各个显示屏保持统一性，有利于简化拼接屏的制作工艺，提高生产效率。
可选地，按照本实施例提供的方式对所述第一显示屏01和所述第二显示屏02进行第一排拼接形成第一排拼接屏后，还可以按照本实施提供的方式在所述第一排拼接屏的一侧形成第二排拼接屏，并将所述第一排拼接屏与所述第二排拼接屏对位拼接，形成完整的拼接屏，从而进一步增大拼接屏的纵向尺寸。
进一步地，本实施例中，将所述第一显示屏01的第二边框302与所述第二显示屏02的第二边框302进行拼接时，需要将所述第二显示屏02相对于所述第一显示屏01旋转180度，但是为了保证所述拼接屏显示画面的一致性，需要依据所述第一显示屏01的显示模式对所述第二显示屏02的显示模式进行对应调整，以保证所述第一显示屏01与所述第二显示屏02均从所拼接屏的同一侧开始显示。
可选地，所述第一边框301包括第一端和与所述第一端相对的第二端。在本实施例中，由于所述第一显示屏01的第二边框302与所述第二显示屏02的第二边框302并排拼接，所以所述第一显示屏01的第一端与所述第二显示屏02的第二端共同位于所述拼接屏的同一侧。所述第一显示屏01由所述第一显示屏01的第一端输入起始显示信号，因此，所述第一显示屏01从其第一端开始显示画面。所述第二显示屏02由所述第二显示屏02的第二端输入起始显示信号，因此，所述第二显示屏02从其第二端开始显示画面。在所述第一显示屏01的第一端与所述第二显示屏02的第二端共同位于所述拼接屏的同一侧的前提下，所述拼接屏从其一侧开始显示画面，从而避免了所述第一显示屏01的显示画面与所述第二显示屏02的显示画面不协调而导致的显示紊乱。
可选地，所述第一显示屏01的第一边框301的宽度B1是所述第一显示屏01的第二边框302的宽度B2的2倍，所述第二显示屏02的第一边框301的宽度B1是所述第二显示屏02的第二边框302的宽度B2的2倍。本实施例可以使形成的拼接屏的拼接缝宽度与所述第一显示屏01的第一边框301的宽度B1以及所述第二显示屏02的第一边框301的宽度B1相等，从而使所述拼接屏呈现出较为规整的外观，提升拼接屏的视觉美观度。
综上所述，本申请实施例提供的拼接屏包括相互拼接的至少两个显示屏，所述显示屏包括外框、背光模组和显示面板，所述外框包括第一边框和与所述第一边框相对的第二边框，所述背光模组包括靠近所述第一边框设置的发光元件，所述显示模组包括靠近所述第一边框设置的覆晶薄膜，相邻两个所述显示屏的至少其中之一沿所述第二边框拼接；本申请实施例通过优化覆晶薄膜和发光元件在显示屏中的位置，使第一边框的宽度大于第二边框的宽度，并以第二边框作为拼接边，使拼接屏具有较小的拼接缝，提升了拼接屏的显示品质和美观度。
本申请实施例还提供一种显示装置，所述显示装置包括本申请实施例提供的拼接屏。
需要说明的是，虽然本申请以具体实施例揭露如上，但上述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。
