Description
本发明涉及Micro-LED显示器技术领域，尤其涉及显示背板、显示设备以及拼接显示设备。
LED(Light Emitting Diode，发光二极管)作为一种新型的固体光源，已经被广泛应用于显示器件中。
微型发光二极管(Micro light emitting diode，MicroLED)通常是指在传统MicroLED芯片结构基础上，将MicroLED芯片尺寸规格缩小到200微米以内的尺寸，将红、绿、蓝三色MicroLED按照一定的规则排列在薄膜晶体管(Thin Film Transistor，TFT)或互补金属氧化物半导体(Complementary Metal Oxide Semiconductor，COMS)上，则形成了能够实现全彩显示的微器件。此种显示器具有独立控制的显示画素，具有独立发光控制、高辉度、低耗电、超高分辨率和超高色彩饱和度等特点，并且MicroLED微显示器件由于具有自发光的技术特性，还可以实现柔性、透明显示等，而其耗电量仅约为液晶面板的10％。
在现有技术中，Micro-led显示器背板上包括了若干像素区域Pixel，每个Pixel包括红色LED、蓝色LED、绿色LED。在显示器制作过程中需要将红绿蓝三色LED芯片转移到显示器背板上，然后进行封装，并切割修边。
当切割出每块显示背板时，难免有切割误差或热影响范∆(e.g.∆=±50um,±100um,…)，随着LED显示器的pitch愈做愈小(e.g.P0.9,P0.6,P0.49,…等小间距显示器)，LED会非常靠近切割边。当切割误差∆无法有效降低时,会导致切割修边困难。若因切割困难而留太多边界也行不通，因为若要做显示屏拼接，边界会影响拼接效果。
有鉴于此，有必要提供一种显示背板、显示设备以及拼接显示设备，可以使背板切割修边更容易。
第一方面，本发明实施例提供一种显示背板。所述显示背板设置有若干像素区域，每个所述像素区域包括三个分别发射不同颜色光的发光二极管；所述显示背板包括至少两个背板，其中发射任意一种颜色光的发光二极管设置于一个背板；发射另外两种颜色光的发光二极管设置于所述至少两个背板中剩余的背板；所述至少两个背板层叠设置，位于一个背板设有发光二极管一侧的另一个背板为透光板。
第二方面本发明实施例提供一种显示设备，所述显示设备壳体以及设置于所述壳体的上述显示背板。
第三方面本发明提供一种拼接显示设备，所述拼接显示设备壳体以及设置于所述壳体的多个上述显示背板，所述多个显示背板拼接在一起。
上述显示背板、显示设备以及拼接显示设备，发光二极管设置于叠放的至少两个背板上，相对于将发光二极管都设置在一个背板上而言，设置相同像素量，发光二极管距离背板的边缘间距更大，从而可以使得对显示背板切割修边更容易。

请参看图1，图1为第一实施方式的显示背板1平面示意图。显示背板1设置有多个像素区域2。每个像素区域2包括三个发光二极管21，三个发光二极管21分别为发射不同颜色的第一单色光的第一发光二极管211、发射第二单色光的第二发光二极管212和发射第三单色光的第三发光二极管213。

在本实施例中，以第一发光二极管211、第二发光二极管212以及第三发光二极管213分别为红色LED、蓝色LED和绿色LED。
当然，在实际使用中，第一发光二极管211也可以为蓝色LED或者绿色LED，第二发光二极管212以及第三发光二极管213同样如此。在此，不作具体限定。
可选地，第一单色光、第二单色光以及第三单色光分别对应红光、蓝光以及绿光。显示背板1可以位于电子显示设备4上，例如，手机，平板电脑，电视机以及其他包含LED显示屏的电子显示设备4中。显示背板1包括至少两个层叠设置的背板。第一发光二极管211、第二发光二极管212、第三发光二极管213中的任意一者设置一个背板上。发射另外两种颜色光的发光二极管设置于至少两个背板中剩余的背板。至少两个背板层叠设置，位于一个背板设有发光二极管一侧的另一个背板为透光板。
请参看图2和图3，在本实施例中，显示背板1包括一个第一背板11和两个第二背板12a和12b。第二背板12b、第二背板12a、第一背板11沿着显示背板1上的发光二极管21的光路方向依次叠放。第一背板11和第二背板12a由透光材料制成。第二背板12b可以为透光材料制成也可以由不透光材料制成。具体地，第一背板11为透光板。透光板可以采用玻璃材料制成的。玻璃材料可以为但不限于以SiO2为主要成分的玻璃材料。
在一些可行的实施例中，还可以采用塑胶透明材料制成，塑胶玻璃材料可以为但不限于聚醚砜（pes）、聚丙烯酸酯（par）、聚醚酰亚胺（pei）、聚萘甲酸乙二醇酯（pet）、聚苯硫醚（pps）、聚α-丙烯酸酯、聚酰亚胺、聚碳酸酯(pc)、三醋酸纤维素（TAC)、乙酸丙酸纤维素（CAP)等。若显示背板1两两相邻的发光二极管21皆按照预设第一间距W1等间距放置。背板上发射同一单色光的两个相邻的发光二极管21之间可放置发射另外两种不同单色光的两个发光二极管21，且两两发光二极管之间的间距为W2。其中，W2= W1/3。下面以第一发光二极管211设置于第一背板11、第二发光二极管设置于第二背板12a、第三发光二极管设置于第二背板12b为例说明。
请再次参看图2，两个第一发光二极管211具有第一间距W1，其中，与第一背板11的边缘E1相邻设置的一个发光二极管211与第一背板11的边缘E1之间的第二间距D1等于W1/2。同样地，两个相邻的第二发光二极管212具有第一间距W1，与第二背板12a的边缘E2相邻设置的一个第二发光二极管212与第二背板12a的边缘E2之间的第二间距D2等于W1/2。两个相邻的第三发光二极管213具有第一间距W1，与第二背板12a的边缘E2相邻设置的一个发光二极管212与第二背板12a的边缘E3之间的第二间距D2等于W1/2。
在本实施例中，当第一背板11、第二背板12a、12b重叠放置时，位于一个像素区域内的第一发光二极管211a、第二发光二极管213a、第三发光二极管213a尺寸相同。第一发光二极管211a、第二发光二极管212a、第三发光二极管213a沿着光路方向上中心O重合。第一发光二极管211a、第二发光二极管212b、第三发光二极管213a完全重叠设置。
当然，在实际使用中，位于一个像素区域内的第一发光二极管211a、第二发光二极管213a、第三发光二极管213a尺寸也可以不相同，例如，第一发光二极管211a的尺寸小于第二发光二极管213a的尺寸，第二发光二极管213a的尺寸小于第三发光二极管213a的尺寸。又或者，第一发光二极管211a的尺寸等于第二发光二极管213a的尺寸，而第二发光二极管213a的尺寸小于第三发光二极管213a的尺寸。在此，不作具体限定。
在本实施例中，第一单色光为红光，即第一发光二极管211发射红光。第二单色光为绿光，即第二发光二极管212发射绿光。第三单色光为蓝光，即，第三发光二极管213发射蓝光。由于红光的透光率小于绿光的透光率，绿光的透光率小于蓝光的透光率。因此，按照以上的方式设置发光二极管，可以使得显示背板1的透光效果更加，使显示效果更优。
在本实施例中，第一背板11、第二背板12a为透光板。第二背板12b为非透光板。在另一些可行的实施例中，第二背板12b也可以为透光板。
在本实施例中，第一发光二极管211、第二发光二极管212、第三发光二极管213分别设置于不同的背板上，相对于将第一发光二极管211、第二发光二极管212、第三发光二极管213都设置在一个背板上而言，设置相同像素量，本实例中的显示背板1中的发光二极管距离对应的背板的边缘间距更大，从而可以使得制作本实施例的显示背板，切割修边更容易。可以理解地，在一些可行的实施例中，第一发光二极管211、第二发光二极管212、第三发光二极管213发射的光的颜色可以无需根据本实施例来设置，也可以达到容易切割修边的效果。
请参看图4，其为第二实施例的显示背板1示意图。第二实施例中的显示背板与第一实施例中的显示背板1不同在于：位于同一背板上的发光二极管中，每相邻的两个发光二极管之间具有第二间距W2。与背板的边缘E4相邻设置的发光二极管21与背板的边缘E4之间的第二间距D2’等于W2/2。可以理解地，在本实施例中，第一发光二极管211、第二发光二极管212、第三发光二极管213分别设置于不同的背板上，相对于将第一发光二极管211、第二发光二极管212、第三发光二极管213都设置在一个背板上而言，在两个相邻的发光二极管之间的间距相同的情况下，本实施例的显示背板具有更高的像素。
请再次参看图5，其为第三实施例显示背板的示意图。第三实施例的显示背板与第一实施例显示背板1差别在于，第一发光二极管211、第二发光二极管212、第三发光二极管213的尺寸不一样，且发射红光的二极管设置于第二背板12b、发射绿光的二极管设置于第二背板12a，发射蓝光的发光二极管设置于第一背板11，且发射红光的二极管的尺寸大于发射绿光的发光二极管的尺寸，发射绿光的发光二极管的尺寸大于发射蓝光的发光二极管尺寸。由于红光的透光率小于绿光的透光率，绿光的透光率小于蓝光的透光率。因此，按照以上的方式设置发光二极管，可以使得显示背板1的透光效果更加，使显示效果更优。
请参看图6在本实施例中，显示背板1包括一个第一背板11和一个第二背板12。第一背板11设置发射一种颜色光的发光二极管211，第二背板12设置分别发射两种颜色的第二发光二极管212和第三发光二极管213。第一背板11和第二背板12重叠放置时，第一发光二极管211设置于第二发光二极管212和第三发光二极管213之间。在本实施例中，第一背板11、第二背板12为透光板；在另一些可行的实施例中，第二背板12也可以为透光板。在一些可行的实施例中，第一背板11设置分别发射两种单色光的第一发光二极管211和第二发光二极管212，第二背板12设置发射一种单色光的第三发光二极管213（如图7所示）。在本实施例中，第一发光二极管211发射红光。
在本实施例中，第一发光二极管211、第二发光二极管212、第三发光二极管213分别设置于不同的背板上，相对于将第一发光二极管211、第二发光二极管212、第三发光二极管213都设置在一个背板上而言，设置相同像素量，本实例中的显示背板1中的发光二极管距离对应的背板的边缘间距更大，从而可以使得制作本实施例的显示背板，切割修边更容易。
请参看图8，其为第一实施例应用该显示背板1的显示设备4示意图，显示设备4包括显示背板1以及固定显示背板1的壳体41，可以理解地，显示设备4具有显示功能。其中，显示设备4包括但不限于显示器、电视机、计算机、笔记本电脑、平板电脑、穿戴式设备等。上述显示设备4由于采用了上述显示背板，即使让显示背板的每个像素区域的尺寸变小，也不影响显示效果和封装修边。
请参看图9，第一实施例应用显示背板的拼接显示设备5示意图。多个显示设备4拼接的拼接显示设备5，在本发明中，拼接显示设备5中的显示设备可以为两个、三个、四个等，在拼接显示设备5中拼接的显示设备4越多时，显示效果越好。在此不在限定。上述拼接显示设备5由于采用了上述显示背板。拼接显示设备5采用了上述任一实施例的显示背板，即便将发光二极管小间距设置于显示背板上，仍然可以容易修边，从而容易设置出发光二极管与背板边缘的窄间距，进而使拼接显示设备5显示效果更佳。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘且本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
以上所列举的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
