Description

发光二极管显示面板 技术领域
本发明有关于显示科技，特别是关于像素排列与发光二极管的反射罩结构，以及其制造方式。
背景技术
这里提供的技术领域的说明，目的仅是为了能够一般性的呈现本发明的整体的脉络。于此所呈现的发明人的工作，关于本技术领域部分中所描述的范围，以及可能于现时不被认为具有现有技术资格的说明内容的各个方面，这些皆未明示地或暗示地被承认为是针对本发明的现有技术。
由于显示器的高分辨率与大尺寸需求，为了高的发光效率，发光二极管显示设备已经成为最受欢迎的显示面板。用于发光二极管显示设备的发光二极管可以是微发光二极管(micro LEDs,μLED)或是次毫米发光二极管(mini LEDs)。举例来说，微发光二极管显示面板使用微发光二极管作为像素单元，能够使得微发光二极管显示面板达到高分辨率、高亮度与高对比度。
然而，由于没有封装与没有反射罩结构的发光二极管的发光模式与其特性，在一个发光二极管显示面板上发光二极管最亮的可视角度，并非垂直于显示面板的可视角度(也就是角度为0度)。此外，对应发光二极管显示面板各个像素的发光二极管的发光模式与特性彼此是一致的。在一些例子，若任何一个发光二极管的功能异常，则使用者将很容易地观察到由于异常的发光二极管所导致的显示异常。
因此，本领域存在至今尚未解决的需求，以解决上述的缺陷与不足之处。

实现本发明的最佳方式
下面结合附图对本发明的结构原理和工作原理作具体的描述：
本说明书中使用的术语一般来说，具有在本领域中所认知到的普通含义，这些术语出现在本说明书关于本发明内容的上下文中，以及出现在使用这些术语的特定上下文段落中。用于描述本发明的某些术语将于下面或说明书中的其他地方讨论，以向从业者提供关于本发明描述的额外导引。为方便起见，例如使用斜体与/或引号以醒目地标示某些术语。对术语使用醒目地标示，对术语的范围与含义并没有影响；术语的范围和含义在相同的上下文中是相同的，无论是否以醒目的方式标示。应理解到，相同的事情可以以不止一种的方式加以说明。因此，替代的用语和同义词可以用于本文所讨论的任何一或多个术语，并且对于术语是否在本文中详细阐述或讨论，也没有任何特殊意义。某些术语的同义词被提出。而一或多个同义词的叙述，并不排除使用其他同义词的使用。本说明书中任何地方的实施例，包括本文所讨论的任何术语的实施例，其仅是说明性质，而并不以此限制本发明或任何示例性术语的范围与含义。同样地，本发明并不限于本说明书中所给出的各种实施方式。
应当理解，当诸如层、膜、区域或基板的元件被称为在另一元件「上」或「连接到」另一元件时，其可以直接在另一元件上或与另一元件连接，或者中间元件可以也存在。相反，当元件被称为「直接在另一元件上」或「直接连接到」另一元件时，不存在中间元件。如本文所使用的，「连接「可以指物理及/或电性连接。再者，「电性连接」或「耦合」可为二元件间存在其它元件。
应当理解，尽管术语「第一」、「第二」、「第三」等在本文中可以用于描述各种元件、部件、区域、层及/或部分，但是这些元件、部件、区域、及/ 或部分不应受这些术语的限制。这些术语仅用于将一个元件、部件、区域、层或部分与另一个元件、部件、区域、层或部分区分开。因此，下面讨论的「第一元件」、「部件」、「区域」、「层」或「部分」可以被称为第二元件、部件、区域、层或部分而不脱离本文的教导。
这里使用的术语仅仅是为了描述特定实施例的目的，而不是限制性的。如本文所使用的，除非内容清楚地指示，否则单数形式「一」、「一个」和「该」旨在包括多形式，包括「至少一个」。「或」表示「及/或」。如本文所使用的，术语「及/或」包括一个或多个相关所列项目的任何和所有组合。还应当理解，当在本说明书中使用时，术语「包括」及/或「包括」指定所述特征、区域、整体、步骤、操作、元件的存在及/或部件，但不排除一个或多个其它特征、区域整体、步骤、操作、元件、部件及/或其组合的存在或添加。
此外，诸如「下」或「底部」和「上」或「顶部」的相对术语可在本文中用于描述一个元件与另一元件的关系，如图所示。应当理解，相对术语旨在包括除了图中所示的方位之外的装置的不同方位。例如，如果一个附图中的装置翻转，则被描述为在其他元件的「下」侧的元件将被定向在其他元件的「上」侧。因此，示例性术语「下」可以包括「下」和「上」的取向，取决于附图的特定取向。类似地，如果一个附图中的装置翻转，则被描述为在其它元件「下方」或「下方」的元件将被定向为在其它元件「上方」。因此，示例性术语「下面」或「下面」可以包括上方和下方的取向。
除非另有定义，本文使用的所有术语(包括技术和科学术语)具有与本发明所属领域的普通技术人员通常理解的相同的含义。将进一步理解的是，诸如在通常使用的字典中定义的那些术语应当被解释为具有与它们在相关技术和本发明的上下文中的含义一致的含义，并且将不被解释为理想化的或过度正式的意义，除非本说明书中明确地这样定义。
在本说明书所使用的词汇例如「大约」或是「近似地」，应一般性认为是在给定数值或是数值范为的百分之二十以内，更好一些是在百分之十以内、再更好一些则是在百分之十以内。说明书中说明给定的数值是近似的，意味着如果没有明确说明，可以推断出术语近似其含义接近所述的「在…的范围」、「大约」或是「近似地」。
接下来将结合附图针对本发明的实施方式做进一步说明。根据本发明的目 的，如本说明书所体现与广泛描述的，在某些方面上，本发明涉及用于无线通信的显示装置结构，而在其侧表面上具有一或多个天线。
如前所述，因为没有封装与反射罩结构的发光二极管的发光模式与特性，发光二极管显示面板的发光二极管的可视角并不是在垂直的可视角(例如角度为0度)。举例来说，图1A根据本发明一些特定的实施方式绘示发光二极管显示面板的子像素的示意图。如图1A所示，子像素100包含二个发光二极管110。图1B与图1C根据本发明一些特定的实施方式绘示如图1A的子像素100的光强度的角分布。而应注意到，在图1B中所提供的子像素100的光强度的角分布，是没有任何的封装结构或是反射罩结构(反射罩结构也称作是反射凸起结构)。如图1B与图1C所示，子像素100的发光二极管110最亮的可视角大约是在正的45度与负的45度，其亮度(brightness)接近于100％。相较之下，在垂直角度(也就是角度为0度)，其亮度仅约为65％。
此外。如前所讨论的，对应发光二极管显示面板像素的发光二极管的发光模式与特性是一致的。举例来说，图2A根据本发明一些特定的实施方式绘示一发光二极管显示面板的显示模式。如图2A所示，发光二极管显示面板200的所有发光二极管朝向相同的垂直可视角发光。在这样的案例下，若发光二极管显示面板200的一个发光二极管210功能异常，如图2B所示，则使用者将能够轻易地察觉异常的发光二极管210所造成的异常。
鉴于上述的缺陷，本发明的一技术态样有关于一种发光二极管显示面板，其中借由对应的反射罩结构，发光二极管显示面板的发光二极管被调整为朝向不同的可视角发光。举例来说，图2C根据本发明一些特定的实施方式绘示发光二极管显示面板的发光模式的示意图。如图2C所示，在发光二极管显示面板200’，发光二极管显示面板200’的发光二极管被调整为朝向不同的可视角发光。在这样的例子下，由发光二极管形成的像素的光强度的角分布能够被调整。此外，若发光二极管显示面板200’的一个发光二极管210’功能异常，如图2D所示，相较于图2B的例子，使用者将不易察觉由异常发光二极管210’所造成的异常。
鉴于上述的缺陷，本发明的一技术态样有关于一种发光二极管显示面板，这种发光二极管显示面板具有形状经设计过的反射罩结构，借以在相似于如图2C所示的方法下调整发光二极管发光的方向。举例来说，图3A根据本发明 一些特定的实施方式绘示发光二极管显示面板的一个像素结构的示意图。应留意到，图3A所示的像素结构，仅是表示是由发光二极管与对应结构所构成的像素结构，并且于接下来的这些结构将不会包含驱动单元或是组件。如图3A所示，发光二极管显示面板300包含背板310与设置于背板310之上的像素结构。具体而言，像素结构320包含多个红像素(R)、多个绿像素(G)以及多个蓝像素(B)。特别是，图3B绘示如图3A所示的红像素320R。如图3B所示，红像素320R包含二个子像素部分320A与320B，子像素部分320A与320B彼此互为镜像。对于第一子像素部分320A，第一反射凸起结构330A为设置于背板(图3B未绘示)之上，并且对于第二子像素部分320B，第二反射凸起结构330B为设置于背板(图3B未绘示)之上。第一反射凸起结构330A与第二反射凸起结构330B借由高光反射材料形成。如图3B所示，第一反射凸起结构330A与第二反射凸起结构330B彼此分离，并且统称为红像素320R的反射罩结构，其中每一个第一反射凸起结构330A与第二反射凸起结构330B的形状都是正三角形(equilateral triangle,或称等边三角形)，且每一个正三角形的转角都具有60度的夹角。具体而言，第一反射凸起结构330A与第二反射凸起结构330B彼此沿一列方向上(例如图3B所示的垂直方向)互为镜像。换句话说，正三角形的第二反射凸起结构330B是正三角形的第一反射凸起结构330A的一镜像形状。第一反射凸起结构330A具有第一开口335A，而第二反射凸起结构330B具有第二开口335B，以分别暴露背板，这使得第一红色发光二极管340A设置在位于第一开口335A之内的发光二极管区域338A。第一开口335A的形状与第二开口335B的形状也可以是正三角形，并且第一开口335A的正三角形与第二开口335B的正三角形彼此沿一列方向上(例如图3B所示的垂直方向)互为镜像。
回去参照图3A，对于在像素结构320内的每一个红像素、绿像素以及蓝像素，子像素部分的排列方式是相似于如图3B所示的红像素320R。换句话说，对于在像素结构320内的每一个像素，第一开口335A的正三角形与第二开口335B的正三角形彼此沿一相同的列方向上(例如图3B所示的垂直方向)互为镜像。
图3C根据本发明的一实施方式示例地绘示如图3B所示的红像素320R沿线段A-A的横截面图。应留意到，图3C的横截面图展示第二子像素部分320B 的横截面，此横截面为垂直于背板310且与第二发光二极管340B交错。因为第一子像素部分320A是第二子像素部分320B的镜像，第一子像素部分320A的细节将会相似于第二子像素部分的横截面，因此在此不再详细说明。
如图3C所绘示，第二反射凸起结构330B具有二个第一侧壁332，二个第一侧壁332对称地位于第二开口335B的两侧。每一个第一侧壁332自背板310向外倾斜延伸，因而于背板310与每一个第一侧壁332之间定义出一锐角α。在一些特定的实施方式中，锐角α的范围是介于20度与80度之间。在一实施方式中，锐角α是68度。第二发光二极管340B位于二个第一侧壁332之间，而第二发光二极管340B至每一个第一侧壁332的距离为距离d。第二发光二极管340B的高度为高度h，而第二反射凸起结构330B的高度是高度H。在一些特定的实施方式中，高度H大于1.5倍的高度h(也就是H>1.5*h)。在这样的结构设计下，第二发光二极管340B与第二反射凸起结构330B可以具有更好的光学效果。
图3D根据本发明的一些特定的实施方式绘示如图3B所示的红像素320R的第一开口335A的形状。应留意到，图3D为展示第一开口335A对应发光二极管区域338A的形状。因为第二开口335B是第一开口335A的镜像结构，而第二开口335B与对应的发光二极管区域338B的形状已见于图3D，因此在此不再详细说明。如图3D所示，发光二极管区域338A的形状是第一开口335A的正三角形的相似三角形。特别的是，第一开口335A具有正三角形PQR，而发光二极管区域338A具有相似正三角形P’Q’R’。在这样的例子下，发光二极管区域338A的相似正三角形的顶点P’、Q’与R’，是位于第一开口335A的正三角形的顶点P、Q与R，以及第一开口335A的正三角形的重心C的连接中线的中点。所以，对于连接重心C至第一开口335A的正三角形的顶点P中线的连接中线，发光二极管区域338A的相似正三角形的顶点P’位于此连接中线的中点。换句话说，顶点P至重心C的长度为长度L，则自顶点P至顶点P’的长度为L/2。因此，第一发光二极管340A可以位于发光二极管区域338A，而发光二极管区域338A区域为相似三角形P’Q’R’所包围。在一些特定的实施方式中，举例来说，第一发光二极管340A可以位于第一开口335A的正三角形的重心C。
图3E根据本发明的一些特定的实施方式绘示如图3B所示的像素的光强 度的角分布。如图3E所示，借由红像素320R的反射罩结构的调整，相较于如图1B所示的光强度的角分布，在每一个方向上的垂直可视角度(及角度为0度)的亮度增加。
如前述所讨论，第一反射凸起结构330A与第二反射凸起结构330B借由高光反射材料形成。在一些特定的实施方式中，于第一反射凸起结构330A与第二反射凸起结构330B之上可以形成金属反射层。举例来说，图3F根据本发明的另一实施方式示意地绘示如图3B所示的像素沿线段A-A的横截面图。具体而言，图3F的横截面不同于图3C的横截面的地方，在于图3F存在设置于第二反射凸起结构330B之上金属层350，这使得二个第一侧壁332’由金属层350所形成。图3F横截面中出现的其他结构与图3C的横截面相同，因此在此不再详细说明。
如前述所讨论，第一开口335A形状是正三角形，而为第一开口335A的镜像结构的第二开口335B，其形状也是正三角形。所以，如图3A所示，对于像素结构320中所有的像素，对应到的第一开口与第二开口皆为正三角形。换句话说，像素结构320中所有像素的第一开口的形状都是相同的。
在如图3B所示的实施方式中，第一反射凸起结构330A与第二反射凸起结构330B是彼此分离的。在一些特定的实施方式中，第一反射凸起结构330A与第二反射凸起结构330B可以彼此连接，这使得第一开口335A与第二开口335B彼此更为靠近。在一些特定的实施方式中，图4根据本发明的另一实施方式绘示如图3A所示的像素的示意图。如图4所示，第一反射凸起结构330A’与第二反射凸起结构330B’彼此连接。具体而言，图4所示的像素400与图3A所示的像素的差异，在于第一开口335A与第二开口335B并非分开的开口。换句话说，第一开口335A与第二开口335B共同形成一个开口。像素的其他结构，包括发光二极管区域338A与338B，以及发光二极管340A与340B，皆相同如图3B所示的红像素320R中具有相同参考标号的对应结构，因此在此不再详细说明。
在如图3A所示的实施方式中，对于在像素结构320中的全部像素，包含红像素、绿像素与蓝像素，每一个像素的第一开口与第二开口设置为以沿相同的列方向彼此互为镜像，如图3B所示。然而，因为每一个像素的第一开口与第二开口的正三角形，每一个像素的第一开口与第二开口的镜像方向将会变 化。举例来说，图5A与图5B根据本发明的两个实施方式绘示两个像素的开口的示意图。如图5A所示，第一开口510与第二开口520沿向右倾斜的方向彼此互为镜像。如图5B所示，第一开口530与第二开口540沿向左倾斜的方向彼此互为镜像。应留意到，像素的不同排列方式不会显著地改变像素光强度的角分布。换句话说，若像素的第一开口与第二开口的位置是以如图5A或是图5B的方式做排列，则如图3B所示像素的光强度的角分布能够保持相同。
图6根据本发明的一些特定的实施方式绘示发光二极管显示面板的像素结构的示意图。如图6所示，发光二极管显示面板600包含背板610与设置于背板610之上的像素结构620。具体而言，图6所示的像素结构620与图3A所示的像素结构320的差异，存在于镜像方向上，而这个镜像方向是第一开口与第二开口的镜像方向。特别的是，如图6所示，像素结构620的像素是排列在一顶列与一底列。在顶列，相似于图5A，每一个像素以向右倾斜的方式排列；而在底列，相似于图5B，每一个像素以向左倾斜的方式排列。换句话说，对于在同一列的每一个像素，每一个像素的第一开口与第二开口的镜像方向是相同的，但两相邻列的镜像方向则彼此不同。此外，如图6所示，对于顶列的红像素620R，在底列与之相邻的像素是蓝像素，这使得在像素结构620中，任何两相邻像素是不同颜色的像素。换句话说，在像素结构620中，任意两相邻像素发出不同波长的光(也就是不同颜色的光)。
在如图3A与图3B所示的实施方式中，每一个像素的第一开口与第二开口是正三角形。在一些特定的实施方式中，每一个像素的第一开口与第二开口的形状可以改变为等腰三角形(isosceles triangle)，而这样的等腰三角形允许像素结构320中像素的排列基本上是相似的。举例来说，图7A根据本发明的一实施方式绘示像素的示意图，而图7B绘示图7A的第一子像素部分。如图7A与图7B所示，像素700包含两个子像素部分700A与700B，两个子像素部分700A与700B彼此互为镜像。而应留意到，因为两个子像素部分700A与700B的位置不同，第一反射凸起结构730A与第二反射凸起结构730B可以是分开的结构。此外，图7A所示的两个子像素部分700A与700B，与图3B所示的两个子像素部分320A与320B的唯一不同处，在于第一开口735A的三角形的底角具有夹角θ。夹角θ的值是可变的，使得第一开口735A的形状(以及对应的第二开口735B的镜像形状)为等腰三角形。当夹角θ是60度，第一开口735A 的形状是正三角形，而相同于图3B。因为形成的发光二极管区域738A的形状是第一开口735A的形状的相似三角形，发光二极管区域738A的形状基于夹角θ也将是可变的。类似的关系也对应到第二开口735B与其发光二极管区域738B。因此在一些特定的实施方式中，第一反射凸起结构730A也可以是可变的。像素700的其他结构，包括第一子像素部分700A的第一发光二极管740A，与另一子像素部分700B的发光二极管740B，皆相似于如图3B所示的对应的结构，因此在此不再详细说明。
图7C、图7D、图7E、图7F与图7G绘示如图7A所示的像素700的光强度的角分布。具体而言，图7C、图7D与图7E根据本发明不同实施方式分别绘示如图7B所示像素的光强度的角分布，这些不同实施方式对应到不同的夹角θ。特别的是，图7C绘示夹角θ为40度的光强度的角分布，图7D绘示夹角θ为50度的光强度的角分布，图7E绘示夹角θ为70度的光强度的角分布。在所有的例子中，像素的发光二极管到每一个对应的反射凸起结构的侧壁的距离，为保持在相同的距离d，如图3C所示。此外，图7F根据本发明的一些特定的实施方式绘示亮度对应如图7A所示的像素700的不同可视角的图表，其中图表中提供的亮度信息包括夹角θ为40度(对应图7C)、夹角θ为50度(对应图7D)、夹角θ为60度(对应图3E)与夹角θ为70度(对应图7E)的情况。对应地，相较于图7F所示的像素对应的信息，为了比较的目的，图7G绘示亮度对应第一子像素部分700A的图表。如图7C、图7D与图7E所示，借由像素320R的反射罩结构的调整，相较于图1B的光强度的角分布，于每个方向上在垂直可视角(也就是角度为0度)的情况时，亮度显著地增加。如图7F与图7G所示，在夹角θ为40度、50度或是60度的例子，像素的发光二极管的最亮可视角接近于垂直可视角(也就是角度为0度)，并且在夹角θ为40度、50度或是70度的例子，在垂直可视角(也就是角度为0度)的亮度大约增加至80％，相对于图1C的65％亮度增加是显著的。
在如上所述的一些实施方式中，开口的形状都是正三角形或是等腰三角形。在一些特定的实施方式中，也可以使用其他的多边形作为开口的形状。举例来说，多边形可包括但不限于三角形、平行四边形、梯形、不规则梯形或四边形，只要每个多边形的至少两个角为小于90°的夹角。
图8A、图8B、图8C、图8D、图9、图10与图11根据本发明的一些不 同的实施方式绘示发光二极管显示面板的像素结构。为了简单说明的目的，每一张附图紧绘示像素结构而未绘示出相对应的背板。此外，对于像素结构中的每一个像素，仅绘示出开口的形状以表示像素，而没有绘示出反射凸起结构与像素的发光二极管。
如图8A所示，在像素结构800中，每一个像素由二个开口所形成，二个开口是以直角三角形的形状沿着行方向(如图8A所示的垂直方向)彼此互为镜像。此外，红像素820R的第一开口与相邻的绿像素的第一开口一起形成一个正方形。在这样的例子，在像素结构800中每一个像素的尺寸与形状是相似的。
如图8B所示，像素结构800’相似于图8A所示的像素结构800，而具有略为不同的排列方式。具体而言，如图8B所示的像素结构800’，仅有部分的像素是以二个开口所形成，其中二个开口是以直角三角形的形状沿着行方向(如图8B所示的垂直方向)彼此互为镜像。一些其他的像素，例如绿像素820G与蓝像素820B，是以沿各别的倾斜方向彼此互为镜像的二个直角三角形的开口形成，使得每一个绿像素820G与蓝像素820B是正方形。在这样的例子，像素结构800’中的每一个像素的形状彼此是不相同的。
如图8C所示，像素结构800”相似于图8B所示的像素结构800’，仅有红像素820R是以沿行方向(如图8C所示的垂直方向)彼此互为镜像的二个直角三角形的开口所形成。一些其他的绿像素820G与蓝像素820B，是以沿各别的倾斜方向彼此互为镜像的二个直角三角形的开口形成，这相似于如图8B所示的绿像素820G与蓝像素820B，使得每一个绿像素820G与蓝像素820B是正方形形状。此外，一些其他的绿像素820G’与蓝像素820B’，是以沿各别的对角线方向彼此互为镜像的二个直角三角形的开口形成，使得绿像素820G’与蓝像素820B’形成对角锯齿形状。在这样的例子下，像素结构800”中的每一个像素的形状彼此是不相同的。此外，绿像素的形状彼此不同，并且蓝像素的形状彼此不同。
如图8D所示，像素结构800”’相似于图8A所示的像素结构800，并更进一步具有不同的像素排列。具体而言，在如图8D所示的像素结构800”’中，取代以二个开口形成像素的作法，红像素820R’为由四个彼此互为镜像的直角三角形开口所形成，使得在一组红像素、绿像素与蓝像素中，红像素820R’与对应的绿像素及蓝像素一起形成一个正方形。在这样的例子下，像素结构 800”’中的每一个像素的形状彼此是不相同的，并且红像素的尺寸是大于绿像素与蓝像素的尺寸。
如图9所示，在像素结构900中，每一个像素为由二个沿行方向(如图9所示的垂直方向)彼此互为镜像的三角形所形成。然而，对于每一个像素，三角形的形状彼此并不相同。具体而言，对于红像素920R，三角形的形状是正三角形，而对于相邻红像素920R的蓝像素与绿像素，三角形是直角三角形，这使得一组红像素、绿像素与蓝像素的第一开口一起形成矩形。在这样的例子，在一组红像素、绿像素与蓝像素中，每一个像素的形状与尺寸彼此是不相同的。然而，所有红像素的第一开口的形状是相同的，所有绿像素的第一开口的形状是相同的，并且所有蓝像素的第一开口的形状是相同的。
如图10所示，在像素结构1000中，每一个像素为由二个沿行方向(如图10所示的垂直方向)彼此互为镜像的四边形所形成。然而，对于每一个像素，四边形的形状彼此并不相同。具体而言，对于红像素1020R，四边形的形状是等腰梯形，而对于相邻红像素1020R的蓝像素与绿像素，四边形是平行四边形，这使得一组红像素、绿像素与蓝像素的第一开口一起形成梯形。在这样的例子，在一组红像素、绿像素与蓝像素中，每一个像素的形状与尺寸彼此是不相同的。此外，红像素1020R(形状为等腰梯形)的第一开口的形状，不同于下一个红像素(形状为平行四边形)的第一开口的形状。换句话说，至少二个红像素的第一开口的形状是彼此不同的。相似地，至少二个绿像素的第一开口的形状是彼此不同的，并且至少二个蓝像素的第一开口的形状是彼此不同的。
如图11所示，在像素结构1100中，每一个像素为由二个三角形或是二个四边形的开口所形成。具体而言，对于像素结构1100中的每一个像素，二个开口不是镜像形状；取而代之的，二个开口彼此是180度的对称。此外，每一个像素的形状彼此不同。具体而言，对于红像素1120R，二个开口于三角形彼此是180度对称。对于绿像素，二个开口于梯形彼此是180度对称。对于蓝像素，二个开口于三角形彼此是180度对称。在这样的例子下，在像素结构1100中每一个像素的形状与尺寸彼此不同。此外，红像素1120R(形状为三角形)的第一开口的形状不同于下一个红像素(形状为梯形)的第一开口的形状。换句话说，至少二个红像素的第一开口的形状是彼此不同的。相似地，至少二个绿像素的第一开口的形状是彼此不同的，并且至少二个蓝像素的第一开口的形状是 彼此不同的。
在上述一些特定的实施方式中，像素的开口的形状与尺寸可以是彼此不同。在一些特定的实施方式中，像素的开口的形状与尺寸可以由像素的发光二极管的发光效率所决定。一般来说，发光二极管的发光效率可以基于发光的发光二极管的波长做变化。举例来说，红色发光二极管的发光效率一般而言是低于绿色发光二极管的发光效率，并且绿色发光二极管的发光效率是低于蓝色发光二极管的发光效率。为了补偿不同发光二极管之间发光效率的差异，可以调整像素的开口的尺寸差异。举例来说，图12A根据本发明的一实施方式绘示在发光二极管的一像素结构内红像素1200R、绿像素1200G与蓝像素1200B尺寸大小的示意图。如图12A所示，每一个红像素1200R、绿像素1200G与蓝像素1200B，是由像素的第一发光二极管与对应的第一开口表示，这些被绘示于一个三角形，并且第一发光二极管1220R、1220G与1220B的尺寸彼此相同。在尺寸彼此相同的第一发光二极管1220R、1220G与1220B的情况下，蓝像素1200B的第一开口1210B的尺寸与面积，是大于绿像素1200G的第一开口1210G的尺寸与面积以及红像素1200R的第一开口1210R的尺寸与面积，并且绿像素1200G的第一开口1210G的尺寸与面积是大于红像素1200R的第一开口1210R的尺寸与面积。
此外，在一些特定的实施方式中，像素的开口的尺寸可以由像素的发光二极管的照度所决定。一般来说，发光二极管的照度可以基于发光的发光二极管的波长做变化。举例来说，绿色发光二极管的照度一般来说显著地优于红色发光二极管与蓝色发光二极管的照度，并且红色发光二极管的照度略优于蓝色发光二极管的照度。为了补偿不同发光二极管之间照度的差异，可以调整像素的反射凸起结构的尺寸差异。举例来说，图12B根据本发明的另一实施方式绘示在发光二极管的一像素结构内红像素1200R’、绿像素1200G’与蓝像素1200B’尺寸大小的示意图。如图12B所示，每一个红像素1200R’、绿像素1200G’与蓝像素1200B’，是由像素的第一发光二极管与对应的第一开口表示，这些被绘示于一个三角形，并且第一发光二极管1220R’、1220G’与1220B’的尺寸彼此相同。在尺寸彼此相同的第一发光二极管1220R’、1220G’与1220B’的情况下，蓝像素1200B’的第一开口1210B’的尺寸与面积，是大于绿像素1200G’的第一开口1210G’的尺寸与面积以及红像素1200R’的第一开口1210R’ 的尺寸与面积，并且红像素1200R’的第一开口1210R’的尺寸与面积是大于绿像素1200G’的第一开口1210G’的尺寸与面积。
应留意到，在图12A与图12B中，并未绘示反射凸起结构。此外，如图12A与图12B所示的像素的第一开口的三角形，仅仅是提供用于说明的目的，而第一开口的形状是可以变化的。
此外，应特别留意到，对于每一个如图12A所示的第一开口1210R、1210G与1210B，以及对于每一个如图12B所示的第一开口1210R’、1210G’与1210B’，所述的第一开口的「尺寸」与「面积」，是参照于第一开口的底部的「尺寸」与「面积」，其中背板裸露。
此外，在如图8D所示的实施方式中，像素的开口的数量可以变化。具体而言，如图8D所示，红像素的开口的数量(在一组红像素、绿像素与蓝像素中有四个)，是多于绿像素的开口的数量(在一组红像素、绿像素与蓝像素中有二个)以及蓝像素的开口的数量(在一组红像素、绿像素与蓝像素中有二个)。所以，像素的开口的数量，可以为了补偿不同发光二极管之间的发光效率或是照度而加以调整。在一些特定的实施方式中，为补偿发光二极管之间发光效率的不同，红像素的开口的数量可以多于绿像素的开口的数量与蓝像素的开口的数量，并且绿像素的开口的数量可以多于蓝像素的开口的数量。在一些特定的实施方式中，为补偿发光二极管之间照度的不同，绿像素的开口的数量可以多于红像素的开口的数量与蓝像素的开口的数量，并且红像素的开口的数量可以多于蓝像素的开口的数量。
应留意到，在上述每一个实施方式中，发光二极管显示面板可以包括其他的结构。举例来说，发光二极管显示面板可以包括一或多个驱动器，以驱动在像素结构中一或多个对应的像素。举例来说，图13A根据本发明的一些特定的实施方式绘示如图3A所示的像素结构内，驱动集成电路与像素的示意图，而图13B根据本发明的一些特定的实施方式绘示如图6所示的像素结构内，驱动集成电路与像素的示意图。如图13A所示，发光二极管显示面板1300包括驱动集成电路1310，驱动集成电路1310通过多根信号线1320连接至像素。具体而言，对于每一个像素，驱动集成电路1310通过相同的信号线1320连接至相通像素的二个子像素。举例来说，对于红像素320R，驱动集成电路1310借由相同的信号线1320连接至相同红像素的二个子像素。相似地，如图13B 所示，发光二极管显示面板1300’包括驱动集成电路1310，驱动集成电路1310通过多根信号线1320连接至像素。因为如图13B所示的发光二极管显示面板1300’的像素排列不同于图13A所示的发光二极管显示面板1300的像素排列，信号线1320的排列也会有所不同。
在一些特定的实施方式中，发光二极管显示面板的驱动器可以是由一个主动矩阵(active)的多个驱动器所形成。举例来说，图14A根据本发明的一些特定的实施方式绘示如图3A所示的像素结构内，主动矩阵层与像素排列的示意图，而图14B与图14C绘示主动驱动单元与对应像素的二个例子。如第14A所示，发光二极管显示面板1400包括主动矩阵，主动矩阵包括多个驱动单元1410。每一个驱动单元1410形成于主动驱动层内的主动矩阵之上，以驱动对应的像素。因为每一个像素包括二个沿行方向上彼此互为镜像的子像素部分，每一个驱动单元1410可以是如图14B与第14C如所示的矩形，使得驱动单元1410可以一对一对应到像素。换句话说，每一个驱动单元1410可以是不同于对应像素的第一开口与第二开口的三角形组合的形状。
图15A根据本发明的一些特定的实施方式绘示如图8A所示的像素结构内，主动矩阵层与像素排列的示意图，而图15B根据本发明的一些特定的实施方式绘示如图15A所示的驱动单元的示意图。如图15A与图15B所示，在发光二极管显示面板1500中，驱动单元1510、1520与1530对应到对应像素的形状。具体而言，驱动单元1510是一个三角形，并且驱动单元1520与1530分别是两个三角形组合的形状。
图15C根据本发明的一些特定的实施方式绘示如图8B所示的像素结构内，主动矩阵层与像素排列的示意图，而图15D根据本发明的一些特定的实施方式绘示如图15C所示的驱动单元的示意图。如图15C与图15D所示，在发光二极管显示面板1500’中，驱动单元1510、1520、1530、1540、1550与1560对应到对应像素的形状。具体而言，驱动单元1510与1540是三角形，驱动单元1520与1530分别是二个三角形组合的形状，而驱动单元1550与1560分别是正方形。
在一些特定的实施方式中，用于发光二极管显示面板的发光二极管的尺寸与形状是可以变化的。一般来说，基于发光二极管的P-N结构，发光二极管可以分类为水平发光二极管、垂直发光二极管或是倒装芯片发光二极管(flip chip  LED)。
图16A根据本发明的一些特定的实施方式绘示水平发光二极管的示意图。如图16A所示，在水平发光二极管结构1600中，发光二极管1620形成于背板1610之上，其中P-N接面1630提供作为主动层。P导线1650连接至发光二极管1620的P电极(例如阳极)，而N导线1660连接至发光二极管1620的N电极(例如阴极)。绝缘层1640覆盖发光二极管1620与N导线1660，而P导线1650通过形成于绝缘层1640的开孔1655连接至发光二极管1620的P电极。
图16B根据本发明的一些特定的实施方式绘示垂直发光二极管的示意图。具体而言，如图16B所示的垂直发光二极管结构1600’，具有于如图16A所示的水平发光二极管结构1600内相似的元件，但元件的形状与位置安排不同。如图16B所示，在垂直发光二极管结构1600’中，发光二极管1620’形成于背板1610之上，其中P-N接面1630’提供作为主动层。P导线1650’连接至发光二极管1620’的P电极(例如阳极)，而N导线1660’连接至发光二极管1620’的N电极(例如阴极)。绝缘层1640’覆盖发光二极管1620’与N导线1660’，而P导线1650’通过形成于绝缘层1640’的开孔1655’连接至发光二极管1620’的P电极。
图16C根据本发明的一些特定的实施方式绘示倒装芯片发光二极管的示意图。具体而言，如图16C所示的倒装芯片发光二极管结构1600”，具有于如图16A所示的水平发光二极管结构1600内相似的元件，但元件的形状与位置安排不同。如图16C所示，在倒装芯片发光二极管结构1600”中，发光二极管1620”形成于背板1610之上，其中P-N接面1630”提供作为主动层。P导线1650”连接至发光二极管1620”的P电极(例如阳极)，而N导线1660”连接至发光二极管1620”的N电极(例如阴极)。应留意到，相较于如图16A所示的发光二极管1620与如图16B所示的发光二极管1620’，如图16C所示的发光二极管1620”倒置，使得P电极位置靠近于背板，因此形成「倒装芯片」结构。在这样的例子，不需要绝缘层覆盖发光二极管1620”，因为P导线1650”与N导线1660”延伸朝向发光二极管1620”的不同侧。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
