Description

异形显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种异形显示装置。
 背景技术
随着显示技术的发展，液晶显示器（Liquid Crystal Display，LCD）和有机发光二极管显示器（Organic Light Emitting Display，OLED）等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
现有的液晶显示装置大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，两片玻璃基板中间有许多垂直和水平的细小电线，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。现有的OLED显示装置通常包括：基板、设于基板上的阳极、设于阳极上的有机发光层，设于有机发光层上的电子传输层、及设于电子传输层上的阴极。工作时向有机发光层发射来自阳极的空穴和来自阴极的电子，将这些电子和空穴组合产生激发性电子-空穴对，并将激发性电子-空穴对从受激态转换为基态实现发光。
随着显示屏在智能穿戴及其他便携式电子设备中应用的广泛，异形显示屏日渐受到消费者的青睐。异形显示屏的出现能进一步满足人们对于显示的要求，如智能手表、可穿戴手机等。种种积极因素促使异形显示屏成为当下显示领域研究的热点之一，其未来的应用市场十分广阔。相比于常规的显示屏，异形显示屏的最大区别就是其显示区域呈现非矩形的不规则形状，因此在异形显示屏的边缘区域，像素单元与显示屏的边界线不能完全匹配，即显示区在边缘区域的像素不是完整的，由此会造成显示屏的边缘区域在显示时会呈现锯齿状的纹路、边缘毛刺现象以及易发生色偏问题，这些都严重影响显示屏边缘区域的显示效果。
 技术问题

 附图说明
为了能更进一步了解本发明的特征以及技术内容，请参阅以下有关本发明的详细说明与附图，然而附图仅提供参考与说明用，并非用来对本发明加以限制。
附图中，
图1为本发明的异形显示装置的第一实施例的示意图；
图2为本发明的异形显示装置的第一实施例的剖面图；
图3为本发明的异形显示装置的第二实施例的示意图；
图4为本发明的异形显示装置的轮廓定义区的示意图。
 本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图1，本发明提供一种异形显示装置，包括异形的有效显示区1，所述有效显示区1包括位于所述有效显示区1的边缘的第一显示区11及与所述第一显示区11相连的第二显示区12；
所述第一显示区11内设有依次排列的多个第一子像素21，所述第二显示区12内设有阵列排布的多个第二子像素22，所述第一子像素21的显示面积小于所述第二子像素22的显示面积。
需要说明的是，本发明中所述的异形具体是指除矩形以外的其他形状，诸如圆形、椭圆形、三角形或其他非矩形的多边形，如图1所示，所述有效显示区1可通过对现有的矩形显示区直接进行切割得到，如图4所示，也可以通过在现有的矩形显示区的边缘形成轮廓定义区2，并在所述轮廓定义区2中设置遮光材料得到。
优选地，如图1、图3及图4所示，在本发明的一些实施例中，所述有效显示区1为圆形，所述第一显示区11包围所述第二显示区12。
进一步地，由于有效显示区1为异形，因此在有效显示区1的边缘会形成一个无法形成完整子像素的区域，即本发明中的第一显示区11，在该第一显示区11内形成有多个不完整的子像素，即本发明中的第一子像素21，而在有效显示区1的其他区域即本发明中的第二显示区12中，则有足够的空间能够形成完整的子像素，即本发明中的第二子像素22，由于第一子像素21为不完整的子像素，因此第一子像素21的显示面积会小于第二子像素22，若不对第一子像素21进行特殊处理，则第一子像素21由于显示面积的减少，必然会导致其亮度不足，从而造成第一显示区11和第二显示区12的显示差异，影响显示品质。
为了解决上述问题，本发明中第一子像素21均经过亮度增强处理，通过所述亮度增强处理能够补偿因第一子像素21和第二子像素22的显示面积的差异而导致的亮度变化，使得在相同数据信号驱动下，所述第一子像素21的亮度与第二子像素22的亮度的差异小于预设的亮度阈值。
优选地，本发明的亮度增强处理，使得在相同数据信号驱动下，所述第一子像素21的亮度与第二子像素22的亮度相等，以最大化提升显示的均一性。
具体地，如图1及图2所示，在本发明的第一实施例中，所述异形显示装置为液晶显示装置。
如图2所示，在本发明的第一实施例中，所述异形显示装置包括相对设置的上基板100和下基板200、位于上基板100和下基板200之间的液晶层300及位于所述下基板200远离所述上基板100的一侧的背光模组400，所述上基板100朝向所述下基板200的一侧形成有彩色滤光膜30。
所述彩色滤光膜30覆盖整个有效显示区1，也即所述第一子像素21及第二子像素22内均设有彩色滤光膜30，在本发明的第一实施例中，通过设置所述第一子像素21内的彩色滤光膜30的膜厚小于第二子像素22内的彩色滤光膜30的膜厚，从而实现亮度增强处理，所述彩色滤光膜30的膜厚越小，背光模块30的光线通过所述彩色滤光膜30时的亮度损失也越小，相应的亮度也会增大，从而能够补偿因显示面积减小而造成的亮度损失。
具体实施时，所述第一子像素21及第二子像素22内的彩色滤光膜30可通过一道半色调光罩或灰阶光罩同时形成。
进一步地，由于所述有效显示区1为异形，第一显示区11中的第一子像素21的随着所述有效显示区1的轮廓变化，各个第一子像素21可能会具有不同的显示面积，因此，此时需要根据每一个第一子像素21的实际的显示面积调整第一子像素21内的彩色滤光膜30的大小，且显示面积越小的第一子像素21内的彩色滤光膜30的膜厚越小。
具体地，如图3所示，在本发明的第二实施例中，所述异形显示装置还可以为OLED显示装置。
在本发明的第二实施例中，所述异形显示装置还包括与所述有效显示区1相连的驱动芯片40，每一个第一子像素21及第二子像素22中均上设有一个有机发光二极管，通过有机发光二极管自发光显示画面，此时有机发光二极管的亮度取决通过有机发光二极管的电流，因此，在本发明的第二实施例中，通过对驱动芯片40的处理算法的设置，使得在相同数据信号驱动下，流过第一子像素21的电流大于流过第二子像素22的电流，从而实现亮度增强处理，流过子像素内的有机发光二极管的电流越大，有机发光二极管的亮度也越高，因此通过增大流过第一子像素21的电流，能够增大第一子像素中有机发光二极管的亮度，从而补偿因第一子像素21的显示面积的减少而造成的亮度损失，提升显示画面的均一性。
进一步地，由于所述有效显示区1为异形，第一显示区11中的第一子像素21的随着所述有效显示区1的轮廓变化，各个第一子像素21可能会具有不同的显示面积，因此，此时需要根据每一个第一子像素21的实际的显示面积调整流过第一子像素21的电流，在相同数据信号驱动下，显示面积越小的第一子像素21流过的电流越大。
综上所述，本发明提供了一种异形显示装置，包括异形的有效显示区，所述有效显示区包括位于所述有效显示区的边缘的第一显示区及与所述第一显示区相连的第二显示区；所述第一显示区内设有依次排列的多个第一子像素，所述第二显示区内设有阵列排布的多个第二子像素，所述第一子像素的显示面积小于所述第二子像素的显示面积；所述第一子像素经过亮度增强处理，以补偿因第一子像素和第二子像素的显示面积的差异而导致的亮度变化，使得在相同数据信号驱动下，所述第一子像素的亮度与第二子像素的亮度相等，能够改善异形显示装置的显示效果，消除异形显示装置有效显示区边缘的锯齿纹路及毛刺，提升异形显示装置的亮度均一性。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。

    所述第一显示区内设有依次排列的多个第一子像素，所述第二显示区内设有阵列排布的多个第二子像素，所述第一子像素的显示面积小于所述第二子像素的显示面积；
    所述第一子像素经过亮度增强处理，以补偿因第一子像素和第二子像素的显示面积的差异而导致的亮度变化，使得在相同数据信号驱动下，所述第一子像素的亮度与第二子像素的亮度的差异小于预设的亮度阈值。
  2. 如权利要求1所述的异形显示装置，为液晶显示装置。
  3. 如权利要求2所述的异形显示装置，其中，所述第一子像素及第二子像素内均设有彩色滤光膜；通过设置所述第一子像素内的彩色滤光膜的膜厚小于第二子像素内的彩色滤光膜的膜厚，从而实现亮度增强处理。
  4. 如权利要求3所述的异形显示装置，其中，所述第一子像素及第二子像素内的彩色滤光膜通过一道半色调光罩或灰阶光罩同时形成。
  5. 如权利要求3所述的异形显示装置，其中，显示面积越小的第一子像素内的彩色滤光膜的膜厚越小。
  6. 如权利要求1所述的异形显示装置，为OLED显示装置。
  7. 如权利要求6所述的异形显示装置，还包括与所述有效显示区相连的驱动芯片，通过对驱动芯片的处理算法的设置，使得在相同数据信号驱动下，流过第一子像素的电流大于流过第二子像素的电流，从而实现亮度增强处理。
  8. 如权利要求7所述的异形显示装置，其中，在相同数据信号驱动下，显示面积越小的第一子像素流过的电流越大。
  9. 如权利要求1所述的异形显示装置，还包括包围所述有效显示区的轮廓定义区，所述轮廓定义区内设有遮光材料。
  10. 如权利要求1所述的异形显示装置，其中，所述有效显示区为圆形或椭圆形，所述第一显示区包围第二显示区。
