具体实施方式
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。
拼缝大小是评价拼接屏的品质的重要指标,因拼接屏产品本身的特点,在中高端拼接屏的设计方案中,通常采用粘接的方式固定显示部件,以实现拼接屏拼缝的最小化。在拼接屏正常生产的过程中,经常会出现需要重工的问题。由于通常采用紫外光固化胶或者热熔胶将显示部件和中框固定粘结,该种通过紫外光固化胶或者热熔胶粘结的方式会导致拼接屏的重工性非常低,最终只能将进行重工处理的拼接屏进行报废处理,这样会导致物料损失严重,使得显示模组的生产成本变高。
目前,极窄拼缝的拼接屏(ULFD)中的显示部件和中框通过紫外光固化胶贴合,显示模组进行重工时需要反向依次拆解背板、中框的连接件和中框,手动向外拆解中框时,显示部件中的显示面板出现碎屏的概率为50%以上, 整个拆解的过程耗时大于1小时,导致显示模组的重工效率低下,且显示模组经过重工后得到完好的显示面板的几率很低。极致拼缝的拼接屏(ELFD)中的显示面板和背光板通过热熔胶进行第一次贴合,背光板和中框通过紫外光固化胶进行第二次贴合,基于第二次贴合,重工需要反向依次拆解背板、中框的连接件和中框,且重工的过程需要使用刀片划开紫外光固化胶,使用刀片的过程造成背光板被划伤及显示面板出现碎屏的概率接近100%,且整个重工的过程耗时大于1小时。另外,由于拼接屏中显示部件的固定方式以及终端的使用特点,拼接屏正常使用时会出现热膨胀的现象,热膨胀会导致开胶的风险大,这样会造成显示模组的维护费用高,而且还会影响产品的寿命。例如,图1为一种显示模组出现开胶现象的截面结构示意图,如图1所示,在受热膨胀的情况下,中框101的与显示部件102接触的部分出现了向右侧移动的现象,从而使得中框101与显示部件102之间出现了开胶的现象,以使得显示部件102与中框101之间的粘结力变弱,且受热膨胀也容易导致中框101形成的容纳空间中设置的导光板、光学膜材、背光元件等出现异常,最终导致整个显示模组的结构变得不稳定,需要进行重工处理。中框101为一个整体结构,当需要将中框101与显示部件102拆开时,需要将中框101与显示部件102之间的粘结胶去除,而在去除粘结胶的过程中容易出现显示部件102被破坏造成其包括的显示面板出现碎屏的情况,因此,显示模组的重工性很差。
本公开的发明人注意到,可以在显示模组的中框的边缘设置可拆卸的支撑部,当需要对显示模组进行重工处理时,可以将支撑部和显示部件的整体从中框上拆卸,从而不需要将粘结支撑部和显示部件的粘结胶去除,这样也不会对显示部件造成破坏。
本公开至少一实施例提供一种显示模组,该显示模组包括:背光模组和显示部件,该背光模组包括中框,该中框的边缘设置有可拆卸的支撑部,该显示部件的边缘和支撑部通过第一粘结胶粘结,且支撑部配置为对显示部件进行支撑,具有上述结构设计的显示模组,当需要进行重工处理时,可以将支撑部、第一粘结胶和显示部件的整体从中框上拆下,以避免常规的处理中用刀片划开第一粘结胶的过程,从而可以避免对显示部件中的显示面板造成损伤。
例如,图2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2所示,该显示模组200包括:背光模组201和显示部件202,该背光模组201包括中框2011,该中框2011的边缘设置有可拆卸的支撑部2012,该显示部件202的边缘和支撑部2012通过第一粘结胶2013粘结,且支撑部2012配置为对显示部件202进行支撑。例如,支撑部2012通过独立的结构设计,可以实现快速从中框2011上拆卸,以使得显示部件202不受影响的前提下,可以大幅度提高显示模组的重工性,以降低生产成本。
例如,将支撑部2012、第一粘结胶2013和显示部件202的整体从中框2011上拆下之后,中框2011形成的容纳空间中设置的光学膜材2014、扩散板2015和导光板2016以及整个背光模组201的其他部分均处于开放的状态,以方便对各个部件进行维修、更换或者进行清洁处理。将支撑部2012、第一粘结胶2013和显示部件202的整体从中框2011上拆下的过程不会造成显示部件202被破坏的风险,同样也没有其他材料的损失,因此不会增加生产成本,且显示模组200的重工性高。
例如,在一个示例中,如图2所示,支撑部2012与中框2011采用局部接触的方式进行连接,该支撑部2012可以进行有限度的形变,以减小第一粘结胶2013由于热膨胀受到的拉伸力,以有效解决显示部件202与背光部件201的粘结处出现开胶的问题,从而可以大幅提升显示模组的品质,降低对显示模组进行维修的成本,以提高市场竞争力。
例如,在一个示例中,如图2所示,该支撑部2012包括靠近显示部件202的第一子支撑部2012a和远离显示部件202的第二子支撑部2012b,在中框2011的边缘具有锁附孔2017,在第一子支撑部2012a和第二子支撑部2012b之间设置有紧固件2018,且至少部分紧固件2018在锁附孔2017中,紧固件2018配置为将第一子支撑部2012a、第二子支撑部2012b和中框2011固定连接。该紧固件2018可以沿着顺时针方向或者逆时针方向旋转以使得第一子支撑部2012a、第二子支撑部2012b和中框2011从稳定连接的状态变成松弛状态,从而使得第一子支撑部2012a和第二子支撑部2012b可以和中框2011分离;对应地,该紧固件2018可以沿着逆时针方向旋转或者沿着顺时针方向旋转以使得第一子支撑部2012a、第二子支撑部2012b和中框2011从松弛状态变成稳定连接的状态,从而使得第一子支撑部2012a和第二子支撑部2012b可以和中框2011分离。
例如,在一个示例中,该第一子支撑部2012a、第二子支撑部2012b与锁 附孔2017配合使用。该锁附孔2017的一部分延伸至中框2011中,该第一子支撑部2012a和第二子支撑部2012b之间具有间隙,该间隙为锁附孔2017的一部分,以使得紧固件2018可以先穿过第一子支撑部2012a和第二子支撑部2012b之间的间隙,再进入锁附孔2017的位于中框2011中的部分,然后将紧固件2018进行旋转使得中框2011可以和第一子支撑部2012a、第二子支撑部2012b固定连接。
例如,在一个示例中,该第一子支撑部2012a和第二子支撑部2012b可以为一个整体的结构,在对应锁附孔2017的位置处具有间隙;该第一子支撑部2012a和第二子支撑部2012b也可以是两个完全分开的结构,第一子支撑部2012a和第二子支撑部2012b可以通过紧固件2018固定连接,本公开的实施例对此不作限定。
例如,在一个示例中,该第一子支撑部2012a、第二子支撑部2012b和紧固件2018的整体为向中框2011的一侧凸起的结构。紧固件2018包括的凸起部在锁附孔2017的位于中框2011中的部分中。
例如,在一个示例中,该紧固件2018包括多点位螺丝,该支撑部2012与中框2011通过多点位螺丝在锁附孔2017处连接。例如,该多点位螺丝可以使得第一子支撑部2012a、第二子支撑部2012b和中框2011在多个位置处通过多个螺丝进行连接,从而使得第一子支撑部2012a、第二子支撑部2012b和中框2011之间的连接更加稳定。图2示出的是显示模组的截面结构,只示出了一个螺丝,可以是多个螺丝在垂直于纸面向里的方向上排布。
例如,如图2所示,在一个示例中,该紧固件2018包括沉头螺丝,沉头螺丝包括沉头2019和螺钉2020,支撑部2012与中框2011通过沉头螺丝在锁附孔2017处连接。例如,一般的螺丝的头部会突出于被连接的物体的表面的上部,使被连接的物体的表面不平整。沉头螺丝包括的沉头2019可以沉到被连接的物体的表面之下,使得被连接的物体的表面平整。
例如,在一个示例中,沉头2019包括靠近显示部件202的第一子沉头2019a和远离显示部件202的第二子沉头2019b,第一子沉头2019a与第一子支撑部2012a的第一配合面2021a的一部分在靠近锁附孔2017的第一边缘位置处接触,且第一边缘为锁附孔2017的靠近显示部件202的边缘;第二子沉头2019b与第二子支撑部2012b的第二配合面2021b的一部分在靠近锁附孔2017的第二边缘位置处接触,且第二边缘为锁附孔2017的远离显示部件202 的边缘。例如,第一子沉头2019a和第二子沉头2019b关于螺钉2020的中心轴成轴对称,第一子沉头2019a的远离螺钉2020的边和第二子沉头2019b的远离螺钉2020的边在一条直线上,且该直线在支撑部2012的最远离中框2011的边的靠近螺钉2020的一侧,或者,该直线与支撑部2012的最远离中框2011的边在一条直线上。
例如,在一个示例中,该第一配合面2021a与第一子沉头2019a的第一夹角α1为8°~12°。例如,该第一夹角α1为8°、9°、10°、11°或者12°。该第二配合面2021b与第二子沉头2019b的第二夹角α2为8°~14°。例如,该第二夹角α2为8°、9°、10°、11°、12°、13°或者14°,本公开的实施例对此不作限定。该第一夹角α1和第二夹角α2的存在使得支撑部2012具有膨胀或者移动的空间,而不容易导致开胶的问题。
例如,在一个示例中,该中框2011与第一子支撑部2012a的第三配合面2021c的一部分在靠近锁附孔2017的第一边缘的位置处接触,第一边缘为锁附孔2017的靠近显示部件202的边缘;中框2011与第二子支撑部2012b的第四配合面2021d的一部分在靠近锁附孔2017的第二边缘的位置处接触,该第二边缘为锁附孔2017的远离显示部件202的边缘。
例如,在一个示例中,该中框2011与第三配合面2021c的第三夹角α3为8°~12°;该中框2011与第四配合面2021d的第四夹角α4为10°~16°,例如,该第三夹角α3的大小为8°、9°、10°、11°或者12°。该第四夹角α4的大小为8°、9°、10°、11°、12°、13°、14°、15°或者16°,本公开的实施例对此不作限定。
例如,需要说明的是,该第三配合面2021c是第一子支撑部2012a的靠近中框2011的面以及接受中框2011施加作用力的面,第四配合面2021d是第二子支撑部2012b的靠近中框2011的面以及接受中框2011施加作用力的面。该第三配合面2021c的与中框2011接触的位置在截面图中可以是一个点或者是一条短线,该第三配合面2021c的一部分不与其他结构接触,以在中框2011和第一子支撑部2012a之间留下一定的膨胀空间。该第四配合面2021d与中框2011接触的位置在截面图中可以是一个点或者是一条短线,该第四配合面2021d的一部分不与其他结构接触,以在中框2011和第二子支撑部2012b之间留下一定的膨胀空间。
例如,在图2中,上述的第一夹角α1、第二夹角α2、第三夹角α3和第 四夹角α4的设置可以确保后续基于显示模组形成的显示装置在使用过程中的温升阶段,显示部件202受热收缩而背光元件受热膨胀产生相对位移量时,支撑部2012可以在一定限度范围内向内侧转动,以使得第一夹角α1增大第三夹角α3减小;且第四夹角α4增大第二夹角α2减小,显示部件202的边缘和支撑部2012之间的第一粘结胶2013因相对移动而受到拉伸力,以使得第一粘结胶2013的靠近导光板2016的一侧的厚度变大,远离导光板2016的一侧的厚度变小,从而可以防止显示部件202和支撑部2012之间出现开胶的现象,以确保显示模组的品质,并提高显示模组的使用寿命,此外,上述设计还可以最大限度地减小紧固件2018对支撑部2012的限制作用。
例如,图3为图2中的显示模组中的支撑部向内侧转动后的截面结构示意图,如图3所示,图2中的第一夹角α1增大为图3中的夹角β1,图2中的第三夹角α3减小为图3中的夹角β3;且图2中的第四夹角α4增大为图3中的夹角β4,图2中的第二夹角α2减小为图3中的夹角β2,显示部件202的边缘和支撑部2012之间的第一粘结胶2013因相对移动而受到拉伸力以使得第一粘结胶2013的靠近导光板2016的一侧的厚度d2变大,远离导光板2016的一侧的厚度d1变小,即d1小于d2,从而可以防止显示部件202和支撑部2012之间出现开胶的现象,以确保显示模组的品质。
例如,在后续形成的拼接屏在周转运输中以及在终端拼接状态下,受到侧向的挤压力时,支撑部2012也可以通过有限度的形变吸收拉伸力,以避免显示部件202和支撑部2012之间出现开胶的现象。
例如,图4为本公开至少一实施例提供的一种中框的受力状态示意图,如图4所示,该显示模组200还包括背板2022,该背板2022配置为支撑中框2011,光学膜材2014、扩散板2015和导光板2016设置在中框2011、显示部件202和背板2022形成的围设空间中,结合图2和图4,光学膜材2014和扩散板2015通过第二粘结胶2024粘结。
例如,如图4所示,中框2011和支撑部2012通过紧固件2018锁附后,中框2011受到紧固件2018施加的作用力F1,且由于背板2022的底板和侧板的支撑作用,中框2011分别受到底板和侧板的作用力F2和F3,因此,对于中框2011会形成一个三角形的受力结构,该三角形的受力状态是一个牢固的受力模型,可以在中框2011受到向内侧的水平推力时,最大限度的确保显示模组的架构不变形。
例如,图5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,如图5所示,该显示模组200包括:背光模组201和显示部件202,该背光模组201包括中框2011,该中框2011的边缘设置有可拆卸的支撑部2012,该显示部件202的边缘和支撑部2012通过第一粘结胶2013粘结,且支撑部2012配置为对显示部件202进行支撑。例如,支撑部2012通过独立的结构设计,即支撑部2012与中框2011采用快拆倒卡的结构进行连接,以实现可以将支撑部2012快速从中框2011上拆卸,以使得显示部件202不受影响的前提下,可以大幅度地提高显示模组的重工性,以降低显示模组的生产成本。
例如,如图5所示,中框2011包括主体部2011a和从主体部2011a的边缘向显示部件202的一侧延伸的延伸部2011b,支撑部2012具有朝向中框2011的开口2012c,该延伸部2011b卡接在该开口2012c中,通过该开口2012c将延伸部2011b卡接的方式实现延伸部2011b与支撑部2012的稳定连接。
例如,如图5所示,该延伸部2011b的延伸方向为第一方向X,垂直于该第一方向X的方向为第二方向Y,该延伸部2011b在垂直于其延伸方向的第二方向Y上具有相对的第一侧边和第二侧边,该第一侧边和第二侧边至少之一上设置有卡扣2023,该卡扣2023配置为调整支撑部2012和延伸部2011b之间的相对运动。即可以仅在第一侧边上设置卡扣2023,也可以仅在第二侧边上设置卡扣2023,还可以同时在第一侧边和第二侧边上设置卡扣2023。当在第一侧边和第二侧边上均设置卡扣2023时,需要将两个卡扣2023对称设置,两个卡扣2023与主体部2011a之间的间距相等,且两个卡扣2023的设置可以使得支撑部2012和延伸部2011b之间的连接更加稳定。
例如,在一个示例中,该卡扣2023和延伸部2011b弹性连接,该卡扣2023弹出延伸部2011b的第一侧边或者第二侧边,即卡扣2023突出于第一侧边或者突出于第二侧边时卡扣2023将支撑部2012和延伸部2011b固定连接,且支撑部2012的靠近主体部2011a的一侧和主体部2011a的靠近支撑部2012的一侧之间具有第一间距W1。该第一间距W1使得需要将支撑部2012从延伸部2011b上拆卸时,可以使得支撑部2012向靠近主体部2011a的一侧运动,同时该卡扣2023被压缩至延伸部2011b中。
例如,在一个示例中,该卡扣2023的截面形状为三角形。例如,该卡扣2023的截面形状为直角三角形,卡扣2023的斜边与支撑部2012接触,以使得支撑部2012向靠近主体部2011a的一侧运动时,卡扣2023的斜边受到支 撑部2012施加的作用力,卡扣2023的两条直角边被逐渐压缩至延伸部2011b中。即该第一间距W1使得支撑部2012可以向靠近主体部2011a的一侧移动,以使得卡扣2023的两条直角边被压缩至延伸部2011b的第一侧边和第二侧边之间,最终使得卡扣2023的斜边的延伸方向平行于第一方向X,此时,支撑部2012和延伸部2011b可以在第一方向X上相对自由运动。
例如,图6A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6A所示,显示部件202包括显示面板202a,以及与显示面板202a层叠设置的背光板202b,该显示面板202a设置在背光板202b的远离中框2011的一侧,且第一粘结胶2013粘结支撑部2012和背光板202b。例如,该背光板202b中分散有扩散材料,以使得背光板202b可以起到对入射至其上的光线进行扩散的作用,该背光板202b还可以对显示面板202a进行支撑。
例如,该显示面板202a包括阵列基板、彩膜基板以及夹置在阵列基板和彩膜基板之间的液晶层,该显示面板的结构和功能可以参见常规的设计,本公开的实施例对此不作限定。
例如,在一个示例中,该背光板202b和显示面板202a采用透明激光胶带202c粘结。该透明激光胶带202c可以实现背光板202b和显示面板202a之间的固定连接和快速拆解,且显示模组的重工耗时短,重工的时间大约为5分钟。当背光板202b或者背光部件出现不良状态时,可以将背光板202b和显示面板202a拆开,且不会影响显示面板202a的整体结构。
例如,图6B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6B所示,显示部件202包括显示面板202a,该显示面板202a设置在背光板202b的远离中框2011的一侧,且第一粘结胶2013粘结支撑部2012和显示面板202a。该背光板202b包括上述提及的光学膜材2014、扩散板2015和导光板2016。
本公开至少一实施例还提供一种拼接屏,该拼接屏包括多个相连的如上述中任一项所述的显示模组。例如,图7为本公开至少一实施例提供的拼接屏的平面结构示意图,如图7所示,该拼接屏30包括多个上述任一实施例提供的显示模组200,尽管图7中示出的是该拼接屏30包括9个显示模组200拼接形成的拼接屏,但是本公开的实施例不限于此,还可以包括其他个数的显示模组200,例如,2个、4个、6个、12个等。多个显示模组200彼此拼接设置,且在任意相邻的两个显示模组200之间形成拼缝。在一些示例中, 该显示模组200可以为液晶显示模组、有机发光二极管(OLED)显示模组或者电泳显示模组。
本公开至少一实施例还提供一种显示装置,例如,图8为本公开至少一实施例提供的显示装置的框图,如图8所示,该显示装置40包括多个上述任一实施例提供的显示模组200,该显示装置40也包括多个显示模组200拼接形成的拼接屏30。本公开的实施例中的显示装置可以为:显示器、OLED面板、OLED电视、电子纸、手机、平板电脑、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。

(3)本公开至少一实施例提供的显示模组,将支撑部、第一粘结胶和显示部件的整体从中框上拆下之后,中框形成的容纳空间中设置的光学膜材、扩散板和导光板以及整个背光模组的其他部分均处于开放状态,可以方便对各个部件进行维修、更换或者进行清洁处理。
(4)本公开至少一实施例提供的显示模组,支撑部与中框采用局部接触的方式进行连接,该支撑部可以进行有限度的形变,可以减小第一粘结胶由于热膨胀受到的拉伸力,以有效解决显示部件与背光部件的粘结处出现开胶的问题,从而可以大幅提升显示模组的品质,降低维修成本,以提高市场竞争力。
