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。同样，“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。
图1为一种Mini-LED的排布方式的示意图。图2为图1所示的排布方式的Mini-LED的模拟混光效果图。
如图1所示，常规Mini-LED的排布方式多采用矩形排布，此种排布方式的模拟混光效果如图2所示。图1示出了多个Mini-LED 21。如图1所示，每个Mini-LED 21包括电极011和电极012，电极011和电极012之一为P电极，电极011和电极012之另一为N电极。
例如，Mini-LED是指芯片尺寸介于50～200μm之间的LED器件。
图1示出了走线70以及走线70中的电流I。图中电流I的箭头表示电流的方向。
对于矩形排布方案，Mini-LED和Mini-LED之间的混光效果较差，如图2中黑色线圈中的区域的亮度明显弱于其余位置，导致灯影(Mura)和周边发蓝等问题。同时，为了考虑打件效率，LED的P电极和N电极采用有序方式放置焊盘，然而，有序排布的P电极和N电极使得发光基板内部走线占用 空间，走线较复杂，电流流经线路长，且内部走线存在多组反向电流间相互作用，线路多会出现电流流经声音，多组反向电流相互作用产生安培力，整面发光基板安培力叠加达到一定数值时，发生的振荡频率与接触处的振荡频率接近一致时，发生共振现象，这种共振引起噪音。
图3为本公开的实施例提供的一种发光模组的示意图。图4为图3中在列方向上相邻的两个分区内的发光元件的示意图。
如图3所示，发光模组包括多个分区20，每个分区20包括多个发光元件10。每个分区20内的发光元件10可由一个或多个驱动芯片进行驱动。例如，每个分区20内的发光元件10可以被同时点亮，但不限于此。分区驱动的方式，利于提高分辨率。图3的一个矩形框即为一个分区20。图3以一个分区20内设有6个发光元件10为例进行说明。
如图3所示，多个分区20沿行方向X和列方向Y排布。
如图3和图4所示，该发光模组包括：多个发光元件10，多个发光元件10在行方向X和列方向Y上排列，相邻两行发光元件10错开排布。如图4所示，同一列发光元件10包括依次设置的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4，并且第二发光元件2和第四发光元件4分设在第一发光元件1和第三发光元件3的中心连线100的两侧。
本公开的实施例提供的发光模组，通过调整发光元件的设置位置和设置方式，使得在同一列的依次相邻的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4中，第二发光元件2和第四发光元件4分设在第一发光元件1和第三发光元件3的中心连线100的两侧，采用此排布方式，使得发光模组的边缘的发光元件的数量相对较少，以利于减少发光模组的边缘的光通量，提升画面品质。在发光元件10均发蓝光的情况下，本公开的实施例提供的发光模组中的发光元件的设置方式，可以改善周边发蓝问题。
如图3和图4所示，多列发光元件沿行方向X依次排布，每列发光元件中的发光元件沿列方向Y排布。
图3示出了一列发光元件中的发光元件10的中心连线60。如图3所示，中心连线60呈折线型。如图3所示，中心连线60包括多个重复部分600，中心连线60的重复部分600连接的发光元件的数量大于3个。如图3所示，中心连线60的重复部分600连接的发光元件的数量为5个。例如，重复部分 600是指中心连线60包括多个形状一致的部分。在一些实施例中，重复部分600是指中心连线60包括多个形状一致并且尺寸一致的部分。图3以重复部分600的形状一致并且尺寸一致为例进行说明。图3中每个矩形框表示的分区20内的点表示发光元件10，图3以一个重复部分600连接5个发光元件为例进行说明，但不限于此，每个重复部分600连接的发光元件的数量可根据需要而定。当然，重复部分600的划分方式不限于图3所示。
如图3所示，最靠近发光模组的边缘的两个相邻的发光元件10(发光元件101和发光元件102)之间设有三个发光元件。即，最靠近发光模组的边缘的两个相邻的发光元件10(发光元件101和发光元件102)之间的发光元件的个数大于一个。如图3所示，在列方向Y上相邻的两个重复部分600中的最靠近发光模组的边缘的两个发光元件10(发光元件101和发光元件102)之间设有三个发光元件。即，在列方向Y上相邻的两个重复部分600中的最靠近发光模组的边缘的两个发光元件10(发光元件101和发光元件102)之间的发光元件的个数大于一个。
如图3所示，发光模组的左侧的中心连线60和发光模组的右侧的中心连线60均呈折线型。如图3所示，发光模组的左侧的中心连线60和发光模组的右侧的中心连线60的弯折方式相同。在本公开的实施例中，发光模组的左侧的中心连线60和发光模组的右侧的中心连线60经平移后可重合。
图3示出了发光模组的中心C0和通过该中心C0的中心线CL。中心线CL沿列方向Y延伸。发光模组的左侧的中心连线60和发光模组的右侧的中心连线60可看成是位于中心线CL的两侧的两列发光元件的中心连线60。
图3示出了发光模组呈矩形，具有边缘E1、边缘E2、边缘E3、以及边缘E4，边缘E1和边缘E3相对设置，且均沿列方向Y延伸，边缘E2和边缘E4相对设置，且均沿行方向X延伸。
在本公开的实施例中，边缘E1、边缘E2、边缘E3、以及边缘E4可分别称作左边缘、上边缘、右边缘、以及下边缘。
在本公开的实施例中，发光元件10的中心是指发光元件10的几何中心。例如，发光元件10的中心是指发光元件10的重心，但不限于此。
如图3所示，发光模组的每列发光元件均为中心连线为折线的一列发光元件。如图3所示，发光模组的每行发光元件均为中心连线为直线的一行发 光元件。从而，图3所示的发光模组的四个边缘中，沿列方向Y延伸的两个边缘的每个边缘处，均设有中心连线为折线的一列发光元件，沿行方向X延伸的两个边缘的每个边缘处，均设有中心连线为直线的一行发光元件。即，在发光模组的四个边缘处，左边缘处的一列发光元件为发光元件的中心连线为折线的一列发光元件，右边缘处的一列发光元件为发光元件的中心连线为折线的一列发光元件，上边缘处的一列发光元件为发光元件的中心连线为直线的一列发光元件，下边缘处的一列发光元件为发光元件的中心连线为直线的一列发光元件。
如图3所示，每列发光元件m0的发光元件的中心连线均为折线。在本公开的实施例中，一列发光元件沿列方向Y排布，但并不要求该列中的发光元件均在一条直线上，一列发光元件的排布趋势沿列方向Y即可。
图4示出了四行三列发光元件。如图4所示，第二发光元件2设在第一发光元件1和第三发光元件3的中心连线100的左侧，第四发光元件4设在第一发光元件1和第三发光元件3的中心连线100的右侧。例如，如图3和图4所示，多列发光元件的设置方式相同。如图3和图4所示，不同列发光元件经平移后可重合。如图3和图4所示，不同列发光元件经在行方向X上平移后可重合。
如图4所示，每相邻两行发光元件10构成一个发光元件组30，且不同的发光元件组30包括不同的发光元件10，相邻的发光元件组30的错开方向相反，以利于减少发光模组的边缘的光通量，提升画面品质。例如，错开方向是指错位的一行发光元件相对于未错位的一行发光元件的错开方向。
如图4所示，发光元件组30包括发光元件组301和发光元件组302。在发光元件组301中的两行发光元件中，在下的一行发光元件相对于在上的一行发光元件向左错开，在发光元件组302中的两行发光元件中，在下的一行发光元件相对于在上的一行发光元件向右错开。
如图4所示，第一行发光元件为未错位的一行发光元件，第二行发光元件为错位的一行发光元件，相对于第一行发光元件向左错开。
如图4所示，第三行发光元件为未错位的一行发光元件，第四行发光元件为错位的一行发光元件，相对于第三行发光元件向右错开。
如图4所示，在列方向Y上相邻的两个发光元件组中发光元件的错开方 式不同。
如图4所示，在列方向Y上相邻的两个发光元件组中发光元件的排布方式不同。
如图3和图4所示，本公开的实施例以奇数行未错位而偶数行错位为例进行说明，但不限于此，在其他的实施例中，也可以奇数行错位而偶数行未错位。
例如，如图4所示，多个发光元件10还包括第五发光元件5和第六发光元件6，第五发光元件5和第六发光元件6与第二发光元件2位于同一行且分别与第二发光元件2相邻，第五发光元件5到第一发光元件1和第三发光元件3的中心连线100的距离D5大于第六发光元件6到第一发光元件1和第三发光元件3的中心连线100的距离D6，第二发光元件2到第一发光元件1和第三发光元件3的中心连线100的距离D2小于第六发光元件6到第一发光元件1和第三发光元件3的中心连线100的距离D6。从而，图4所示的第二行发光元件与第一行发光元件相比向左错开。
例如，如图4所示，为了获得较好的混光效果，第六发光元件6到第一发光元件1和第三发光元件3的中心连线100的距离D6为第二发光元件2到第一发光元件1和第三发光元件3的中心连线100的距离D2的3到10倍。进一步例如，距离D6为距离D2的3到8倍。
例如，如图4所示，多个发光元件10还包括第七发光元件7和第八发光元件8，第七发光元件7和第八发光元件8与第四发光元件4位于同一行且分别与第四发光元件4相邻，第七发光元件7到第一发光元件1和第三发光元件3的中心连线100的距离D7小于第八发光元件8到第一发光元件1和第三发光元件3的中心连线100的距离D8，第四发光元件4到第一发光元件1和第三发光元件3的中心连线100的距离D4小于第七发光元件7到第一发光元件1和第三发光元件3的中心连线100的距离D7。从而，图4所示的第四行发光元件与第三行发光元件相比向右错开。
例如，如图4所示，第一行发光元件与第三行发光元件在行方向X上不错位。
例如，如图4所示，为了获得较好的混光效果，第七发光元件7到第一发光元件1和第三发光元件3的中心连线100的距离D7为第四发光元件4 到第一发光元件1和第三发光元件3的中心连线100的距离D4的3到10倍。进一步例如，距离D7为距离D4的3到8倍。
例如，如图4所示，为了获得较好的混光效果，第二发光元件2的中心到第一发光元件1和第三发光元件3的中心连线100的距离D2等于第四发光元件4的中心到第一发光元件1和第三发光元件3的中心连线100的距离D4。即，距离D2等于距离D4。该设置使得第二行发光元件相对于第一行发光元件向左错开的距离等于第四行发光元件相对于第三行发光元件向右错开的距离。
例如，如图4所示，第二发光元件2、第三发光元件3、以及第四发光元件4的中心连线在一条直线L234上。
例如，如图4所示，第一发光元件1和第二发光元件2的中心连线100与直线L234的夹角A0为钝角。例如，该钝角大于或等于120度并且小于或等于160度。
图4示出了第一发光元件1的中心C1和第三发光元件3的中心C3。例如，各个发光元件的中心可以为该发光元件的重心，但不限于此。
图4示出了发光元件的第一电极11和第二电极12。第一电极11和第二电极12之一可以为P电极，第一电极11和第二电极12之另一可以为N电极。例如，各个发光元件的中心可以位于第一电极11和第二电极12之间。
例如，如图4所示，位于同一行且相邻的两个发光元件10之间的距离相等。例如，如图4所示，位于同一列且相邻的两个发光元件10之间的在列方向Y上的距离相等。
例如，在本公开的实施例中，行方向X和列方向Y相交。例如，行方向X为水平方向，列方向Y为竖直方向。本公开的实施例以行方向X和列方向Y垂直为例进行说明。在列方向Y上的多个发光元件10的总体走势在列方向上，并不要求列方向Y上的多个发光元件10按照直线排列。同一列发光元件可以按照非直线例如折线方式排列。
参考图3和图4，在一列分区20中，隔行的分区20中的发光元件的排布方式相同。如图3所示，偶数行的分区20内的发光元件的排布方式相同，奇数行的分区20内的发光元件的排布方式相同。如图3所示，偶数行的分区20内的发光元件的排布方式和奇数行的分区20内的发光元件的排布方式不 同。例如，每个分区20包括多个发光元件中的至少两个发光元件。采用此排布方式，发光模组的边缘发光元件相对较少，可改善周边发蓝问题。
图5为本公开的实施例提供的发光模组中的发光元件的排布方式示意图。
例如，如图4和图5所示，发光元件10包括第一电极11和第二电极12，位于同一行的两个相邻发光元件10的第一电极11和第二电极12的排布方向不同。从而，使得同一行的两个相邻发光元件的第一电极11和第二电极12交错设置，使得布局中的走线简单，简化走线布置，有效减少电流流动声音，有效减少反向电流相互作用产生的安培力引起的振荡频率。
例如，如图4和图5所示，位于同一行的两个相邻发光元件10的第一电极和第二电极的排布方向相反。如图4所示，在第一行发光元件中，第二列的发光元件中的第一电极11和第二电极12按照从上至下的方式设置，第三列的发光元件中的第一电极11和第二电极12按照从下至上的方式设置。
例如，如图4和图5所示，发光元件10具有长轴A1和短轴A2，长轴A1的延伸方向垂直于短轴A2的延伸方向，长轴A1的长度大于短轴A2的长度，发光元件10的第一电极11和第二电极12的排布方向为长轴A1的延伸方向。例如，长轴A1为发光元件10的相对的两个短边的中心连线，短轴A2为发光元件10的相对的两个长边的中心连线。
例如，如图4和图5所示，各个发光元件10的长轴A1的延伸方向为列方向Y，各个发光元件10的短轴A2的延伸方向为行方向X。
图5示出了走线70以及走线70中的电流I。
图6为采用图4的发光元件的设置方式的发光模组的混光效果图。如图6所示，此种排布方式临近的发光元件的混光效果均匀，无发暗现象，同时，发光模组的边缘光通量相对矩形排布较少，采用此种排布方式，不仅可有效提升画面品味，还可有效减少发光元件的数量(例如，通过提升发光元件的电流达到亮度)，节约成本。在发光元件均发蓝光的情况下，此种排布方式可有效解决周边发蓝问题。
图7为本公开的实施例提供的发光模组中的发光元件的排布方式示意图。
例如，如图7所示，奇数列和偶数列之一中的发光元件10的长轴A1的 延伸方向为列方向Y，奇数列和偶数列之另一中的发光元件10的长轴A1的延伸方向为行方向X。
例如，如图7所示，奇数列和偶数列之一中的发光元件10的长轴A1的延伸方向垂直于奇数列和偶数列之另一中的发光元件10的长轴A1的延伸方向。
例如，如图7所示，即，奇数列的发光元件10竖向放置，偶数列的发光元件10横向放置。
如图7所示，奇数列和偶数列之一中的发光元件10沿列方向Y放置，奇数列和偶数列之另一中的发光元件10沿行方向X放置，相邻列且位于同一行的两个发光元件10交错放置，即，一个发光元件沿列方向Y放置，一个发光元件沿行方向X放置。
例如，如图7所示，相邻两列发光元件10中的一列发光元件10的长轴的延伸方向平行于列方向Y，相邻两列发光元件10中的另一列发光元件10的长轴的延伸方向平行于行方向X。
在本公开的实施例中，竖向放置、沿列方向Y放置、横向放置、沿行方向X放置均指发光元件10的第一电极11和第二电极12的排布方向的设置方式，或指发光元件10的长轴A1的延伸方向的设置方式。
图7示出了不同分区20之间的沿行方向延伸的分隔线501。图7所示的分隔线501即为图3所示的表示分区20的矩形框的一部分。
图8为本公开的实施例提供的发光模组中的发光元件的排布方式示意图。
例如，如图8所示，多个发光元件10中的至少一个发光元件10的长轴A1的延伸方向与行方向X的夹角a1大于0。
例如，如图8所示，多个发光元件10中的至少一个发光元件10的长轴的延伸方向与行方向X的夹角a1大于0并且小于或等于45°。

图8示出了不同分区20之间的沿行方向延伸的分隔线501和沿列方向延伸的分隔线502。
例如，如图3、图4、图7和图8所示，在本公开的实施例中，每个分区 可以设置两行三列共6个发光元件。
例如，如图3至图5、图7和图8所示，在同一分区20中，相邻的四个发光元件形成平行四边形的排布方式。
图9为本公开的实施例提供的一种发光模组的示意图。图10为本公开的实施例提供的一种发光模组的示意图。
如图9和图10所示，为了进一步提升发光模组周边的亮度的均一性，使得光源均一性更好，在发光模组的沿列方向Y延伸的相对的两个边缘处，发光模组分别具有中心连线为直线的至少一列发光元件。
图9和图10示出了发光模组呈矩形，具有边缘E1、边缘E2、边缘E3、以及边缘E4，边缘E1和边缘E3相对设置，且均沿列方向Y延伸，边缘E2和边缘E4相对设置，且均沿行方向X延伸。
图9和图10以在边缘E1具有一列中心连线为直线的一列发光元件，并且在边缘E3具有一列中心连线为直线的一列发光元件为例进行说明，但不限于图中所示。在其他的实施例中，边缘E1处的中心连线为直线的发光元件的列数可根据需要而定，边缘E3处的中心连线为直线的发光元件的列数可根据需要而定。
例如，为了兼顾避免周边发蓝以及周边亮度均一性，边缘E1处的中心连线为直线的发光元件的列数小于或等于四，边缘E3处的中心连线为直线的发光元件的列数小于或等于四。即，在边缘E1具有小于或等于四列的中心连线为直线的发光元件，并且在边缘E3具有小于或等于四列的中心连线为直线的发光元件。在边缘E1处，这些中心连线为直线的多列发光元件依次排布，并且在边缘E3处，这些中心连线为直线的多列发光元件依次排布。
如图9和图10所示，除了边缘E1和边缘E3处之外，发光模组的每列发光元件均为中心连线为折线的一列发光元件。如图9和图10所示，发光模组的每行发光元件均为中心连线为直线的发光元件行。从而，图9和图10所示的发光模组的四个边缘中，沿列方向Y延伸的两个边缘的每个边缘处，均设有中心连线为直线的一列发光元件，沿行方向X延伸的两个边缘的每个边缘处，均设有中心连线为直线的一行发光元件。

如图9和图10所示，在多个第一类型列发光元件m01中，两个相邻发光元件10之间在行方向X上的距离为df。例如，距离d1等于距离df，距离d2小于距离df，距离d3等于距离df，距离d4大于距离df。
如图9和图10所示，距离d1、距离d2、距离d3、以及距离d4分别为最靠近沿列方向Y延伸的边缘的第一类型列发光元件m01中的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4和与其最接近的第二类型列发光元件m02中的发光元件之间的最小距离。距离d1、距离d2、距离d3、以及距离d4也可以看成最靠近沿列方向Y延伸的边缘的第一类型列发光元件m01中的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4和与其最接近的第二类型列发光元件m02中的发光元件的中心连线所在的直线之间的最小距离。
如图10所示，在边缘E3处，最靠近沿列方向Y延伸的边缘的第一类型列发光元件m01中的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4和与其最接近的第二类型列发光元件m02中的发光元件的中心连线所在的直线之间的最小距离先增大再逐渐减小。
如图10所示，在边缘E3处，最靠近沿列方向Y延伸的边缘的第一类型列发光元件m01中的第一发光元件1、第二发光元件2、第三发光元件3、以及第四发光元件4和与其最接近的第二类型列发光元件m02中的发光元件的中心连线所在的直线之间的最小距离分别为距离da、距离db、距离dc、以及距离dd。
