具体实施方式
为减少背光模组中的发光二极管由于静电原因导致的损坏,从而减少显 示装置的静电损失,延长显示装置的使用寿命,本公开实施例提供了一种显示装置。为使本公开的目的、技术方案和优点更加清楚,以下举实施例对本公开作进一步详细说明。
图1为本公开实施例提供的显示装置的俯视结构示意图,图2和图4为本公开实施例提供的显示装置的截面示意图,图3为本公开实施例提供的显示装置的侧视图。
本公开提供了一种显示装置,如图1和图2所示,包括:
显示面板2;
背光模组1,背光模组1包括发光二极管灯组8;
显示面板2包括沿远离背光模组1方向依次设置的第一基板5和第二基板6,第一基板5包括未被第二基板6覆盖的非遮挡区(如图中虚线框A所示),发光二极管灯组8在第一基板5的正投影位于非遮挡区A中;
保护盖板12,保护盖板12位于显示面板2的出光侧;
机壳15,位于背光模组1背离显示面板2的一侧,且机壳15接地设置;
导电结构18,导电结构18在第一基板5的正投影与发光二极管灯组8在第一基板5的正投影至少存在部分交叠区域,且导电结构18连接保护盖板12与机壳15。
本公开实施例提供的显示装置,通过将机壳接地设置,并设置连接保护盖板与机壳的导电结构,且该导电结构在第一基板上的正投影与发光二极管灯组在第一基板上的正投影具有至少部分交叠区域,当在显示装置具有发光二极管灯组所在的边角处有静电传导过来时,导电结构可以通过机壳将静电进行释放,防止静电对发光二极管灯组产生影响,减少发光二极管由于静电导致的损坏,从而减少显示装置的静电损伤,延长显示装置的使用寿命。
参照图2,在显示装置的使用过程中,由于手指触摸显示屏或者显示装置的表面与其他物体之间的摩擦,因而在保护盖板12一侧容易产生静电,此外,由于机壳15一般为整面设置的导体,且机壳15接地设置,因而机壳15具有比较好的静电释放能力,通过设置连接机壳15与保护盖板12的导电结构18, 可以构成立体的静电防护系统,当保护盖板12表面或者显示装置的侧边处产生静电,静电可以通过导电结构18传导至机壳15释放,从而起到保护发光二极管灯组8的作用。
此外,由于导电结构18在第一基板5的正投影与发光二极管灯组8在第一基板5的正投影至少存在部分交叠区域,因而,导电结构18可以在垂直于显示面板表面的方向上遮挡至少部分发光二极管灯组8,从而缓解垂直于显示面板表面的方向上的静电对发光二极管灯组8的损伤。
在本公开实施例中,上述显示面板2可以为液晶显示面板,背光模组1中的发光二极管灯组8可以位于背光模组1的一个侧边处,也可以位于背光模组1的两个或多个侧边处,此处不做限定,发光二极管灯组8中可以包括多个发光二极管14,一般可以将发光二极管14排列成一行或多行,此处不对发光二极管14的个数和排列方式进行限定。
具体地,本公开实施提供的上述显示装置中,同样参照图1和图2,还包括:与第一基板5连接的柔性电路板11;
柔性电路板11包括第一接地端(图中未示出),导电结构18与第一接地端电连接。
通过将导电结构18与柔性电路板11上的第一接地端连接,可以将静电通过第一接地端传导到大地进行释放,增加了静电释放的路径,当显示装置的周边区域产生静电后,可以通过导电结构18传导至柔性电路板11的第一接地端释放,也可以传导至机壳15上进行释放,提高了静电释放的能力和速度,从而进一步缓解静电对发光二极管灯组8的损伤,从而能够有效的提高静电释放的效率,提升显示装置的使用寿命。
具体地,本公开实施例提供的上述显示装置中,如图1和图2所示,上述导电结构18,包括:位于第一基板5靠近第二基板6一侧的导电屏蔽层9;
导电屏蔽层9位于第一基板5的非遮挡区A内,且导电屏蔽层9在第一基板5上的正投影至少覆盖发光二极管灯组8中
一个发光二极管14在第一基板5上的正投影;
第一基板5在非遮挡区A内设有接触衬垫(图中未示出);
导电屏蔽层9与接触衬垫电连接,第一接地端与接触衬垫电连接。
在实际应用中,柔性电路板11中的第一接地端可以与位于非遮挡区A内的接触衬垫连接,而接触衬垫与导电屏蔽层9均位于第一基板5的非遮挡区A内,因而可以通过导线等导体连接接触衬垫与导电屏蔽层9,从而实现导电屏蔽层9与第一接地端的电连接。此外,导电屏蔽层9在第一基板5上的正投影至少覆盖一个发光二极管14在第一基板5上的正投影,从而可以阻挡在第一基板5靠近保护盖板12一侧产生的静电对发光二极管的损伤,这样不仅能够起到对发光二极管14的静电防护,还能够减少静电屏蔽层9的涂覆范围,从而降低显示模组的生产成本。
在具体实施时,在第一基板5的非遮挡区A内可以设置驱动芯片或其他走线,为了避免导电屏蔽层9与驱动芯片或其他走线短路,本公开实施例提供的显示装置中,导电屏蔽层9在第一基板5上的正投影覆盖发光二极管灯组8两端的发光二极管14在第一基板5上的正投影,从而防止静电从发光二极管灯组8的两端处传输至发光二极管,而损伤发光二极管,此外,对于位于发光二极管灯组8内部的发光二极管14,非遮挡区A内的其他走线也可以起到静电防护的作用,因此,将导电屏蔽层9设置为在第一基板5上的正投影遮挡两端处的发光二极管就能起到良好的防静电的作用。
具体地,本公开实施例提供的上述显示装置中,导电屏蔽层9的材料包括透明导电材料,例如可以采用氧化铟锡(Indium tin oxide,ITO)等透明导电氧化物材料。这样可以在实现静电释放的同时不影响显示模组显示效果。
具体地,本公开实施例提供的上述显示装置中,如图2和图3所示,导电结构18,包括:导电缓冲部13,以及导电连接部10;
导电缓冲部13的一端与保护盖板12面向第一基板5一侧连接,另一端在非遮挡区的位置处与第一基板5连接;
导电连接部10贴附于第一基板5和背光模组1与发光二极管灯组8对应的侧边处,且导电连接部10与导电缓冲部13搭接;
导电缓冲部13在第一基板5上的正投影与柔性电路板11在第一基板5上的正投影无交叠;
导电连接部10与柔性电路板11无搭接区域。
导电缓冲部13填充于第一基板5的非遮挡区与保护盖板之间,且导电缓冲部13在第一基板5上的正投影与柔性电路板11在第一基板5上的正投影无交叠,从而将导电缓冲部13避开柔性电路板11,防止产生短路,影响柔性电路板11的功能,此外,可以将导电缓冲部13通过导电屏蔽层9与第一基板5连接,从而使导电缓冲部13与柔性电路板11的第一接地端实现电连接。
此外,通过在导电连接部10贴附于第一基板5和背光模组1的侧边处,可以通过导电连接部10的一端与导电缓冲部13搭接,另一端直接或间接与机壳15搭接,从而实现导电缓冲部13与机壳15之间的电连接,而且,导电连接部10与柔性电路板11无搭接区域,因而导电连接部10不会影响柔性电路板11朝向机壳15背面弯折。
进一步地,本公开实施例提供的上述显示装置,参照图2和图3,保护盖板12在靠近显示面板2的一侧设有接地设置的第二接地端(图中未示出);
导电缓冲部13与第二接地端电连接。
在具体实施时,为了便于使导电缓冲部13与第二接地端实现电连接,可以将第二接地端设置在保护盖板12与导电缓冲部13相对的位置处,从而使第二接地端与导电缓冲部13可以直接接触连接。通过将导电缓冲部13与第二接地端连接,增加了导电结构18的静电释放路径,例如当显示装置在背光模组一侧出现静电时,静电可以在机壳15处释放一部分,静电可以传导至柔性电路板11上的第一接地端进行释放,也可以传导至保护盖板12上的第二接地端进行释放,或者当显示装置在保护盖板12一侧出现静电时,静电可以传导至保护盖板12上的第二接地端释放一部分,也可以传导至柔性电路板11上的第一接地端进行释放,也可以传导至机壳上进行释放,从而提高了导电结构的静电释放能力,并且可以迅速将静电导走,防止静电对发光二极管灯组8或者其他结构的影响。
具体地,本公开实施例提供的上述显示装置,如图2和图3所示,导电结构18,还可以包括:位于背光模组1靠近机壳15一侧的导电层3;
导电层3与导电连接部10搭接,且与机壳15电连接。
通过在背光模组1与机壳15之间设置导电层3,且通过导电层3与导电连接部10搭接,相比于将导电连接部10直接与机壳15连接,提高了导电性能,从而使静电能够通过机壳15顺利导出。
这样设置可以形成导电层3、导电连接部10以及导电屏蔽层9的导电通路。当有静电从显示装置的机壳15的一侧传导过来时,静电首先通过导电层3传递到导电连接部10,再通过导电连接部10传递到第一基板5上的导电屏蔽层9,由于导电屏蔽层9接地设置,因此,静电便通过导电屏蔽层9传递到大地,从而完成静电的释放。
此外,为了进一步保护发光二极管灯组8,导电层3在第一基板5上的正投影至少覆盖发光二极管灯组8在第一基板5上的正投影,也就是说,可以将导电层3设置为仅在于发光二极管灯组8对应位置处的条形区域,从而可以阻挡从背光模组1靠近机壳15一侧的静电对发光二极管灯组8的损伤,而且可以在保证导电层3导电性能的同时减少导电层3的设置范围,从而降低显示模组的生产成本。
具体地,导电层3的材料可以包括石墨,可以是石墨粘结层后者石墨涂层,也就是可以通过涂覆或者贴附的方式将导电层3形成在背光模组1靠近机壳15的一侧。
在具体实施时,本公开实施例提供的上述显示装置中,上述导电缓冲部的材料包括导电泡棉,采用导电泡棉形成导电缓冲部,能够比较好的填充在第一基板5与保护盖板12之间,保证保护盖板上的第一接地端与导电结构能够良好接触。
具体地,本公开实施例提供的上述显示装置中,导电连接部10为导电胶涂层,在制作过程中,可以将导电胶涂层直接贴附于显示面板2和背光模组1的侧边处,操作简便。导电连接部可以为面状的导电胶涂层,也可以为线状 的导电胶涂层。导电胶涂层设置为面状时可以有效的提高静电传导的效率。而当在显示模组周边区域产生静电并传导至发光二极管所在区域的静电量较少,以及为了节省生产成本可以将导电胶涂层设置为多条线状的导电胶涂层
在实际应用中,本公开实施例提供的上述显示装置中,上述背光模组1,还可以包括:位于发光二极管灯组8背离显示面板2一侧的金属背板16,以及位于发光二极管灯组8与金属背板16之间的反射片4;
金属背板16与导电结构18电连接。
此外,背光模组1一般还可以包括导光板17,发光二极管灯组8可以设置在导光板17的侧边处,反射片4设置于导光板17与金属背板16之间,反射片4可以将导光板17在靠近金属背板16一侧的光线再次反射回导光板17,从而提高光线利用率。可以将金属背板16与导电层3直接搭接,从而实现金属背板16与导电结构18的电连接,从而可以延长静电传输的路径,防止静电损伤发光二极管灯组。
此外,由于金属背板16可以导电,也可以通过金属背板16连接导电连接部10与机壳15,因而可以省略导电层3,由金属背板16与反射片4贴合的表面实现静电传导的功能。这时可以形成金属背板16、导电连接部10以及导电屏蔽层9的导电通路。当有静电从显示模组的下方传导过来时,静电首先通过导电层3传递到导电连接部10,再通过导电连接部10传递到第一基板5上的导电屏蔽层9,由于导电屏蔽层9接地设置,因此,静电便通过导电屏蔽层9传递到大地,从而完成静电的释放。
本公开实施例提供的上述显示装置,通过将机壳接地设置,并设置连接保护盖板与机壳的导电结构,并且,将导电结构设置为与柔性电路板上的第一接地端以及与保护盖板上的第二接地端连接,从而在立体形态上形成了多个静电释放路径,当一个位置处出现静电,可以将静电向多个位置传导进行释放,静电释放能力较强,可以防止静电对发光二极管灯组产生影响,减少发光二极管由于静电导致的损坏,从而减少显示装置的静电损伤,延长显示装置的使用寿命。
尽管已描述了本公开的优选实施例,但本领域内的技术人员一旦得知了基本创造性概念,则可对这些实施例作出另外的变更和修改。所以,所附权利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然,本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开实施例的精神和范围。这样,倘若本公开实施例的这些修改和变型属于本公开权利要求及其等同技术的范围之内,则本公开也意图包含这些改动和变型在内。
