Description

显示面板、显示装置和子像素的渲染方法 技术领域
本发明涉及显示面板和显示装置，可以用作各种手机、平板电脑、笔记本电脑、显示器、电视机等各种设备的彩色显示面板和显示装置，还涉及显示装置的子像素的渲染方法。
背景技术
当前广泛使用的各种彩色显示屏，如阴极射线管(Cathode Ray Tube,CRT)显示屏，发光二极管(light-emitting diode,LED)显示屏、有机发光二极管(Organic Light Emitting Diode,OLED)显示屏、液晶显示屏(liquid crystal display,LCD)等，都是由像素排列而成的。一个彩色显示屏包含有多个像素，如640x480，1024x768，1920x1080个像素等。每个像素包括两个或三个或更多个不同颜色的子像素。其中比较常见的是每个像素有三个子像素，即红色子像素、绿色子像素、蓝色子像素。三个子像素平行排列，形成一个像素。
为了防止显示的图像变形，每个像素一般都是正方形的，因此，子像素是长方形的，其宽高比为3：1，如图1所示。多个像素重复排列形成彩色显示屏如图2。当然，这些像素有些是自发光的，如LED彩色显示屏、主动矩阵有机发光二极体面板(Active Matrix/Organic Light Emitting Diode,AMOLED)彩色显示屏等，有些自身并不发光而是靠背光来统一提供光源，如被动式有机电激发光二极管(Passive matrix OLED,PMOLED)彩色显示屏、LCD彩色显示屏等。
彩色显示屏的一个重要指标是每英寸像素数(PPI)，即彩色显示屏的像素密度。当前彩色显示屏发展的一个重要方向，就是提高彩色显示屏的像素密度。高分辨率的手机屏幕、电脑屏幕，以及正在火热发展中的4K电视等，都对彩色显示屏的像素密度提出了越来越高的要求。如苹果电脑公司生产的 Retina彩色显示屏通过降低每个像素的尺寸来获得高分辨率的彩色显示屏，已经用于苹果手机、平板电脑、笔记本电脑等。这种直接增加像素密度的方法，带来了两个难以克服的问题，一是制造工艺复杂，成品率低，从而导致高分辨率的彩色显示屏价格高；二是像素密度的提高意味着每个像素面积的缩小，而子像素之间是有黑色间隔的。因此，子像素面积的降低使得子像素之间的间隔所占的面积比增加，从而使得光源的利用率降低，为达到同样亮度的彩色显示屏的能耗显著增加。这对于手机、平板电脑、笔记本电脑等移动设备来说，是一个致命的弱点。
为了在提高像素密度的同时，降低彩色显示屏的生产成本和使用过程中的能耗，三星公司提出了多种新的彩色显示屏设计和制造方法。该公司在Pentile RGBW彩色显示屏及Pentile RGBG彩色显示屏中，通过降低每个像素中子像素的数量，来提高像素密度。其中RGBW彩色显示屏具有四色(红、绿、蓝、白)子像素，但每个像素都只有两个子像素，即蓝-白，或红-绿，参见图3。而在RGBG彩色显示屏中，具有普通的三色子像素，但每个像素都只有两个子像素，即绿-蓝，或绿-红，参见图4。这些彩色显示屏在不降低每个子像素的尺寸的前提下，提高了彩色显示屏的像素密度。相比于苹果公司的Retina彩色显示屏而言，具有低功耗、低成本的优点。其中RGBW彩色显示屏已用于如下设备中：
·Motorola MC65
·Motorola ES55
·Motorola ES400
·Motorola Atrix4G
·Samsung Galaxy Note10.1 2014version
·Lenovo Yoga2Pro
·HP ENVY TouchSmart14-k022tx Sleekbook
RGBG彩色显示屏是三星非常成功的一个彩色显示屏，已广泛地用于多种手机中，如下：
·BlackBerry Q10
·Nexus One
·HTC Desire(AMOLED variants only)
·Samsung S8000
·Samsung Galaxy S
·Samsung Galaxy S Plus
·Samsung Galaxy S III
·Samsung Galaxy S III Mini
·Samsung Galaxy S4
·Samsung Galaxy Note
·Samsung Wave S8500
·Samsung Ativ S
·Samsung NX10
·Nexus S(Super AMOLED variants only)
·Galaxy Nexus
·Dell Venue Pro
·Nokia N9
·Nokia Lumia800
·Nokia Lumia925
·Nokia Lumia928
·Nokia Lumia1020
·HTC One S
·Pantech Burst
·Huawei Ascend P1
·Alcatel One Touch Star6010D
·Motorola RAZR i
除了上述通过降低子像素数量来提高像素密度的方法以外，变结构子像素彩色显示屏则通过改变子像素的结构，来获得更高的像素密度和更好的显示效果，如三星的S-Strip彩色显示屏，如图5所示，蓝色子像素为一长条，而红绿色子像素为小四方块，交叉排列形成一个像素。三星彩色显示屏技术相关专利如图6所示，其中2010年的手机Galary S和2012年的手机Galary S3采用了PenTile RGBG彩色显示屏(由RG像素和BG像素)，2011年的手机Galary S2采用了Stripe彩色显示屏(RGB像素)，2012年的手机Galary Note2采用了S-Stripe彩色显示屏(RGB像素)。
综上可见，目前提高像素密度的主要方法是降低单个像素内子像素数量。这种方法在提高像素密度的同时，降低了黑色的像素间隔区的比例，提高了光源的利用率，降低了同等亮度的能耗。但是这种方法相比于传统的三原色子像素方法，降低了图像的质量，使得显示的图像有一定程度的偏色。

具体实施方式
为了使本领域技术人员更好地理解本发明，下面结合附图和具体实施方式对本发明作进一步详细说明。
首先，说明本文中一些术语的含义。
术语“像素”，又称画素，为图像显示的基本单位，译自英文“pixel”，pix是英语单词picture的常用简写，加上英语单词“元素”element，就得到pixel，故“像素”表示“图像元素”之意。每个像素可有各自的颜色值，因而有了对应的“子像素”概念，例如像素可采三原色显示，因而又分成红、绿、蓝三种子像素(RGB色域)，或者可采用青、品红、黄和黑四种子像素(CMYK色域，印刷行业以及打印机中常见)，或者还可采用红、绿、蓝、白四种子像素(RGBW色域)，或者采用更多的原色表示。
术语“原色”(也称为“基色”)表示重复的子像素群组中的每一种颜色，例如RGB子像素中的红色(R)、绿色(G)、蓝色(B)被称为三原色，RGBW子像素中的红色(R)、绿色(G)、蓝色(B)、白色(W)也是原色。
本文中术语“相邻的像素对之间”，是指在像素组中按照像素排列的顺序， 顺次由两个像素组成像素对，各个像素对之间不存在重复的像素，将描述在这样相邻的像素对之间的情况。例如，在如后文将描述的例子中，四原色八元像素组“P1 P2 P3 P4 P4 P1 P2 P3 P3 P4 P1 P2 P2 P3 P4 P1”中，按照从左至右的顺序，第一个像素包含子像素P1 P2，第二像素包含子像素P3 P4，第三个像素包含子像素P4 P1，第四个像素包含子像素P2 P3，类推直至第八个像素包含子像素P4 P1。其中第一、第二像素，第三、第四像素，第五、第六像素，第七、第八像素顺次两两组成像素对。每个像素对内包含P1、P2、P3、P4四个原色子像素。这里第一像素对由第一、第二像素组成，第二像素对由第三、第四像素组成，第三像素对由第五、第六像素组成，第四像素对由第七、第八像素组成；而并不存在由第二像素和第三像素组成的像素对、由第四像素和第第五像素组成的像素对，等等。
后续示例中，将主要以子像素种类为RGB子像素的情况为例进行描述，不过本发明并不局限于此，子像素(原色)的种类和数目可以不同。
本公开提供了一种显示面板，由像素组重复组成，像素组由设置在一行的预定数目个像素组成，各个像素由至少二种不同原色的子像素按照不同顺序排列组成，以及其中像素组中相邻的像素之间相邻的子像素或相邻的像素对之间的颜色相同，以及像素组中第一个子像素和最后一个子像素的颜色相同。所述的相邻的同色子像素增加了所显示颜色的饱和度，使得本发明提出的彩色显示屏比现有的彩色显示屏具有更高的颜色饱和度，显示的颜色更加鲜艳，层次更加丰富。
例如，显示屏主要由像素组重复组成，像素组由设置在一行的三个像素组成。每个像素由红、绿、蓝三种颜色的三个子像素所组成。像素组中相邻的像素之间相邻的子像素的颜色相同，以及像素组中第一个子像素和最后一个子像素的颜色相同。例如，像素组中三个像素的所有子像素的一种示例性排列方式为：红色子像素、绿色子像素、蓝色子像素，蓝色子像素、红色子像素、绿色子像素，绿色子像素、蓝色子像素、红色子像素，如图7(a)所示。像素组中三个像素的所有子像素的另一种示例性排列方式为：红色子像素、蓝色像素、绿色子像素、绿色子像素、红色子像素、蓝色子像素、蓝色子像素，绿色子像素、红色子像素，如图7(b)所示。
需要说明的是，前述图7(a)和图7(b)中所示的示例中，像素组以红色子 像素开始以及以红色子像素结束，不过这仅为示例，实际上像素组中的开始子像素和结尾子像素可以为其它颜色的子像素。
实际上，根据本发明的一个实施例的显示屏可以概括为：三原色子像素组成像素，三个不同像素排在一行中组成像素组，像素组重复形成显示屏。换言之，假设以P1、P2、P3分别表示第一原色、第二原色、第三原色子像素，像素组中三个像素的所有子像素以下列方式排列在一行中：
P1 P2 P3 P3 P1 P2 P2 P3 P1
注意，这里的P1、P2、P3分别为三个原色中的一种，且彼此不同。需要说明的是，虽然后文中通常以P1为红色，P2为绿色和P3为蓝色为例加以说明，但实际上P1可以为绿色或蓝色，相应地P2和P3任一个也可以为其它颜色。优选地，一个像素组中的所有子像素包括了所有原色的子像素，且各原色子像素的数量在同一个像素组内相等，这可以避免显示的图像偏色，保证显示质量。
在本发明上述实施例中，由九个子像素排列形成三个相邻的像素所构成的三元像素组，为称呼简便，可以将此种三元像素组称为陶氏三元像素(Tao’s Triple Pixels,TTP)。再由多个TTP重复排列，形成彩色显示屏，可称之为陶氏三元像素显示屏(Tao’s Triple Pixel Display,TTPD)，如图8所示。可见，传统的彩色显示屏由像素排列而成，而本发明实施例的陶氏三元像素显示屏(TTPD)是由陶氏三元像素(TTP)重复排列而成，该显示屏的特点是所有相邻像素之间，相邻子像素的颜色相同。
实际上，根据本发明的另一个实施例的显示屏可以概括为：四原色子像素组成像素对，四对八个像素排在一行中组成像素组，像素组重复形成显示屏。换言之，假设以P1、P2、P3、P4分别表示第一原色、第二原色、第三原色、第四原色子像素，像素组中四对八个像素的所有子像素以下列方式排列在一行中：
P1 P2 P3 P4 P4 P1 P2 P3 P3 P4 P1 P2 P2 P3 P4 P1
注意，这里的P1、P2、P3、P4分别为四个原色中的一种，且彼此不同。像素组中第一个像素包含子像素P1 P2，第二像素包含子像素P3 P4，第三个像素包含子像素P4 P1，第四个像素包含子像素P2 P3，直至第八个像素包含子像素P4 P1。其中第一、第二像素，第三、第四像素，第五、第六像素，第七、第八像素顺次两两组成像素对，也即该示例中第一像素对为P1 P2 P3 P4， 第二像素对为P4 P1 P2 P3，第三像素对为P3 P4 P1 P2，第四像素对为P2 P3 P4P1。每个像素对内包含P1、P2、P3、P4四个原色子像素，即每四个原色的相邻子像素组成一个像素对。需要说明的是，虽然文中通常红色、绿色、蓝色、白色为例表示四原色，但实际上四原色也可以为其它颜色。优选地，一个像素组中的所有子像素包括了所有原色的子像素，且各原色子像素的数量在像素组内相等，这可以避免显示的图像偏色，保证显示质量。
在本发明上述实施例中，由八个像素排列形成四对相邻的像素对所构成的八元像素组，为称呼简便，可以将此种八元像素组称为陶氏八元像素(Tao’s Octagonal Pixels,TOP)。再由多个TOP重复排列，形成彩色显示屏，可称之为陶氏八元像素显示屏(Tao’s Octagonal Pixel Display,TOPD)。传统的彩色显示屏由像素排列而成，而本发明实施例的陶氏八元像素显示屏(TOPD)是由陶氏八元像素(TOP)重复排列而成，该显示屏的特点是所有相邻像素对之间，相邻子像素的颜色相同。
上面分别以三原色的三元像素组，四原色的八元像素组为例进行了说明。不过，这仅为示例，实际上像素组可以由更多个像素组成。
例如，同样，以P1、P2、P3分别表示第一原色、第二原色、第三原色子像素，这里只需要P1、P2、P3为三种原色之一且彼此不同即可，并不需要P1、P2、P3为固定的原色。例如，可以按照下列二种方式中的一种来构成像素组。
例如，第一种方式：像素组由五个像素组成，每个像素由三原色子像素排列形成，像素组中五个像素的子像素以下列方式排列在一行中：
P1 P2 P3 P3 P1 P2 P2 P3 P1 P1 P3 P2 P2 P3 P1
再例如，第二种方式：像素组由六个像素组成，，每个像素由三原色子像素排列形成，像素组中六个像素的子像素以下列方式排列在一行中：
P1 P2 P3 P3 P1 P2 P2 P3 P1 P1 P3 P2 P2 P1 P3 P3 P2 P1
需要说明的是，前面以三原色的三、五、六元像素组，四原色的八元像素组为例进行了说明。不过这仅为示例，显示屏可以有更多种原色或像素组内有更多个像素。实际上，根据本发明实施例的彩色显示屏的构成只要满足如下条件即可：显示屏由像素组重复组成，像素组由设置在一行的预定数目个像素组成，各个像素由不同原色的子像素按照不同顺序排列组成，其中至 少有二种原色，以及其中像素组中相邻的像素之间(例如，三原色的情况)或相邻的像素对之间(例如，四原色的情况)相邻的子像素的颜色相同，以及像素组中第一个子像素和最后一个子像素的颜色相同。
一般地，为了防止显示的图像变形，每个像素一般都是正方形的。在一个示例中，设像素组由N个像素组成，设置像素组的宽高比为N：1，从而使得每个像素平均是正方形，其中N为大于等于3的整数。
得到像素组后，像素组重复排列得到显示屏。在实际制造显示屏中，通常制造好很大的显示板后，对该大的显示板进行切割，得到需要大小的显示屏。在本文中，“显示屏”和“显示面板”具有相同涵义，可互换使用。
需要说明的是，在本文中，将显示屏或显示面板描述为“主要”由像素组重复组成，这是因为，如本领域技术人员公知的，由于显示面板的尺寸和/或生产因素或限制会导致显示面板的一个或多个边缘处的像素组不完整。
像素组重复排列可以形成彩色显示屏，重复排列的方法有多种，可以包括行间同色排列和行间异色排列，行间同色排列是指各行之间的相应位置的子像素的颜色是相同的，行间异色排列是指各行之间的相应位置的子像素的颜色存在不同。对于根据本发明实施例的彩色显示屏，无论是行间同色还是行间异色排列，其共同特征是同一行内任意两个相邻的像素之间相邻的两个子像素的颜色相同。所述的相邻的同色子像素增加了所显示颜色的饱和度，使得本发明提出的彩色显示屏比现有的彩色显示屏具有更高的颜色饱和度，显示的颜色更加鲜艳，层次更加丰富。
图8(a)、(b)、(c)、(d)分别示出了子像素、像素组、行间同色排列的显示屏的一部分、行间异色排列的显示屏的一部分的示意图，其中图8(a)示出了红、绿、蓝子像素；图8(b)示出了像素组，其子像素排列为红、绿、蓝、蓝、红、绿、绿、蓝、红；图8(c)示出了行间同色排列的显示屏的一部分；如图所示不同行间的对应像素之间颜色是相同的，表现为每列中的子像素颜色都相同，如第一列中子像素都是红色，第二列中子像素都是绿色，等等；图8(d)示出了行间异色排列的显示屏的一部分的示意图，如图所示不同行间的对应像素之间颜色存在不同，表现为每列中的子像素颜色不都是相同的，例如第一列中的四个子像素颜色为红、红、蓝、绿，第二列中子像素颜色为绿、红、红、蓝，等等。
在一个示例中，将像素组中相邻像素的相邻的同色子像素组成的对以及 像素组之间的相邻像素的相邻的同色子像素组成的对中的一对或多对合并而成为强子像素,该合并得到的强子像素中不存在黑色间隔，且其亮度大于被合并的原同色子像素的任一个的亮度。这样的强子像素配置减少了显示屏中的黑色间隔，提高了光源的利用率，降低了彩色显示器的功耗。
例如，对于前文所述的陶氏三元像素，可以将陶氏三元像素内九个子像素中相邻的两个颜色相同的子像素选择性地合并成一个强子像素。例如，将陶氏三元像素内的相邻的两个蓝色子像素合并为一个蓝色强子像素，如图9(a)所示。再例如，将陶氏三元像素内的相邻的两个绿色子像素合并为一个绿色强子像素，如图9(b)所示。再例如，将像素组之间的相邻像素的相邻的同色子像素合并为一个强子像素，例如将图7(a)中所示的一个陶氏三元像素与相邻的陶氏三元像素之间的相邻红色子像素合并为一个红色强子像素，如图9(c)所示。在图9(a)、(b)、(c)所示示例中，每九个子像素(或者说每一个陶氏三元像素)内含有一个强子像素。根据陶氏三元像素内强子像素的颜色不同，共有三种不同的陶氏三元像素，即含有一个红色强子像素的陶氏三元像素TTP-R、含有一个绿色强子像素的陶氏三元像素TTP-G、含有一个蓝色强子像素的陶氏三元像素TTP-B。一个彩色显示屏内，可以含有一种或多种具有不同颜色强子像素的陶氏三元像素。需要说明的是，图9(a)、(b)、(c)中以及后续附图，将强子像素显示为宽度比其他子像素宽的子像素。
在前述示例中，一个陶氏三元像素内含有一个强子像素。不过，这仅为示例，一个陶氏三元像素内可以包含两个强子像素，或者说每九个子像素内含有两个强子像素。根据陶氏三元像素内强子像素的颜色不同，共有三种不同的陶氏三元像素，即含有一个红色强子像素和一个绿色强子像素的陶氏三元像素TTP-RG(图10(a))、含有一个绿色强子像素和一个蓝色强子像素的陶氏三元像素TTP-GB(图10(b))、含有一个蓝色强子像素和一个红色强子像素的陶氏三元像素TTP-BR(图10(c))。一个彩色显示屏内，可以含有一种或多种具有不同颜色强子像素的陶氏三元像素。
在一个示例中，在平均意义上，一个陶氏三元像素内可以包含三个强子像素，或者说平均意义上每九个子像素内含有三个强子像素。一个陶氏三元像素内含有三个强子像素(TTP-3，TTP-RGB)。如图11(a)所示，一个彩色显示屏内，只有一种陶氏三元像素TTP-RGB。同样地，在一个示例中，在平均意义上，一个陶氏八元像素内可以包含四个强子像素，或者说平均意义 上每十六个子像素内含有四个强子像素。一个陶氏八元像素内含有四个强子像素(TOP-4，TOP-RGBW)。如图11(b)所示，一个彩色显示屏内，只有一种陶氏八元像素TOP-RGBW。
图12(a)、(b)、(c)示出了根据本发明实施例的每个陶氏三元像素内含有一个强子像素的示例性彩色显示屏的一部分，其中图12(a)、(b)为行间同色排列，图12(c)为行间异色排列。更具体地，图12(a)中的显示屏中只有一种陶氏三元像素TTP-B，即每个陶氏三元像素仅含有蓝色强子像素；图12(b)中的显示屏中有二种陶氏三元像素TTP-B和TTP-G，即含有一个蓝色强子像素的陶氏三元像素和含有一个绿色强子像素的陶氏三元像素；图12(c)中的显示屏中有二种陶氏三元像素TTP-B和TTP-G，即含有一个蓝色强子像素的陶氏三元像素和含有一个绿色强子像素的陶氏三元像素。图13(a)、(b)示出了根据本发明实施例的每个陶氏三元像素内含有两个强子像素的示例性彩色显示屏的一部分，其中图13(a)为行间同色排列，图13(b)为行间异色排列。图14(a)、(b)示出了根据本发明实施例的每个陶氏三元像素内含有三个强子像素的示例性彩色显示屏的一部分，其中图14(a)为行间同色排列，图14(b)为行间异色排列。
本发明上述实施例的彩色显示器特征是同一行内任意两个相邻的像素之间相邻的两个子像素的颜色相同，其中若干相邻的同色子像素被合并为强子子像素，在强子像素中消除了黑色间隔。所述相邻同色子像素或强子像素增加了所显示颜色的饱和度，使得本发明实施例的彩色显示屏比现有的彩色显示屏具有更高的颜色饱和度，显示的颜色更加鲜艳，层次更加丰富；而且所述强子像素提高了光源的利用率，降低了彩色显示器的功耗。
强子像素的发光强度可以大于原相邻的两个子像素(由该两个子像素合并得到该强子像素)的发光强度的任一个，例如为原相邻的两个子像素(由该两个子像素合并得到该强子像素)的发光强度之和。产生强子像素的方法可以有多种，例如：
·在AMOLED、LED等主动发光彩色显示屏中，可以通过增加强子像素所对应的发光单元的发光强度，来实现强子像素。例如，强子像素的面积可以和普通子像素一样，但其发光强度可以为原相邻的两个同色普通子像素之和。相应地，由于子像素的平均宽度缩小了，陶氏三元像素的高度也需要作调整，使得陶氏三元像素的宽高比为3：1，即每个像素平均是正方形。
·在PMOLED、LCD等被动发光彩色显示屏中，可以通过增加强子像素所对应的发光单元的面积，来实现强子像素。在这种情况下，强子像素的面积比普通子像素的面积大，其发光强度也大于原相邻的两个同色普通子像素的任一个的发光强度，例如为原相邻的两个同色普通子像素之和。一般情况下，由于去除了两个相邻同色子像素之间的黑色间隔，强子像素的发光效率提高，其面积一般小于两个子像素之和。因此，由于子像素的平均宽度有所缩小，陶氏三元像素的高度也需要作调整，使得陶氏三元像素的宽高比为3：1，即每个像素平均是正方形。
更一般的情况是，在像素组由N个像素组成的情况，其中像素组的宽高比为N：1，从而使得每个像素平均是正方形，其中N为大于等于3的整数。
需要说明的是，前面的示例性显示屏中，示出了相邻同色的子像素未被合并的显示屏和相邻同色的子像素选择性地被合并的显示屏，不过这些仅为示例，例如在一个显示屏中，可以既包括相邻同色的子像素未被合并的像素组(即，不包含强子像素的像素组)也包括相邻同色的子像素被合并的像素组(即，包含强子像素的像素组)，另外相邻同色的子像素被合并的数目和方式也可以根据需要进行选择。
作为示例，显示面板可以是液晶显示面板、发射式电致发光显示面板、等离子显示面板、场致发射显示面板、电泳显示面板、闪光显示面板、白炽显示面板、发光二极管显示面板、以及有机发光二极管显示面板等。
此外，原色或基色的数目和种类可以根据需要进行设计，例如除了红色、绿色、蓝色的三原色外，还可以选择红色、绿色、蓝色、白色的四原色，以及还可以包括其他的原色，例如青色、洋红色等等。
图15示出了根据本发明实施例的显示装置100的配置框图，该配置框图仅示出了与本发明实施例密切相关的部件，该配置并非限制性的，也非穷尽性的，而是还可以包括其他部件。
如图15所示，显示装置100可以包括输入图像接收部件110、子像素渲染部件120、驱动部件130和显示面板140。
输入图像接收部件110用于接收第一格式的输入图像数据，以供以所述输出显示格式使得显示装置渲染。输入图像数据的格式可以为常规的三色“全像素”RGB格式，也可以为其它的sRGB、YCbCr、RGBW格式等等，输出 显示格式由显示屏中子像素的布局决定。在输入图像数据的颜色空间与输出的颜色空间不同的情况下，输入图像接收部件110可以包括对输入图像数据进行色域映射的功能，例如，如果输入数据为RGB格式，要在RGBW显示面板上进行渲染，则需要进行色域映射操作，以便利用面板上的W原色。当然，取代将这样的色域映射功能并入输入数据接收部件110，这样的色域映射功能也可以由独立于映射数据接收部件110的其它部件或者专门的色域映射部件来实现。
子像素渲染部件120用于基于输入图像数据(包括经过例如色域映射处理的输入图像数据)执行子像素渲染操作，以产生所述显示面板上每个子像素的亮度值。基于这样的亮度值，驱动部件130向显示面板的每一个子像素发送信号，从而实现第一格式的输入图像数据以令观察者愉悦的方式显示在显示面板上。即，子像素渲染(rendering)操作为显示面板上的每个子像素提供亮度值。
显示面板140可以为上面描述的本发明实施例的显示面板，其主要由像素组重复组成，像素组由设置在一行的预定数目个像素组成，各个像素由至少二种不同原色的子像素按照不同顺序排列组成，以及其中像素组中相邻的像素之间相邻的子像素的颜色相同，以及像素组中第一个子像素和最后一个子像素的颜色相同。
下面描述根据本发明实施例的子像素亮度的确定方法示例。
作为对比，首先描述传统的显示器的子像素亮度的确定方法。
图16(a)-(d)示出了传统的显示器的从图像数据到面板显示的原理图，其中图16(a)示出了具有多个像素的一幅彩色图像的部分输入图像数据；其中Pij表示第i行第列的像素的部分输入图像数据，i和j为大于等于0的整数；图16(b)具体示出图16(a)所示图像中的6个像素P0-P5的颜色值，分别为(R0G0,B0),…,(R5G5,B5)；图16(c)示出了传统RGB显示器直接根据图16(b)的数值显示图像，即显示器上一个像素的子像素的颜色值直接对应于图像上的对应像素中的子像素的颜色值；图16(d)示出了传统RGBG显示器只根据图16(b)中的部分数值显示图像，例如对于输入图像的第一列像素数据，其对应于图16(d)中的显示面板的左起的第一列和第二列的R0和G0列子 像素，从而丢弃了对应输入像素数据中的B0颜色值；对于输入图像的第二列像素数据，其对应于图16(d)中的显示面板的左起的第三列和第四列的B1和G1列子像素，从而丢弃了对应输入像素数据中的R1颜色值；如此等等。
图17(a)-(d)示出了根据本发明实施例的陶氏三元像素显示屏(TTPD)从图像数据到面板显示的原理图，其中图17(a)示出了具有多个像素的一幅彩色图像的部分输入图像数据；其中Pij表示第i行第列的像素的部分输入图像数据，i和j为大于等于0的整数；图17(b)具体示出图17(a)所示图像中的6个像素P0-P5的颜色值，分别为(R0,G0,B0),…,(R5,G5,B5)；其颜色值为(R0,G0,B0),…,(R5,G5,B5)；图17(c)示出了根据图14(a)中子像素的排列方式，从相邻的、颜色相同的、两个子像素的颜色数值(例如亮度)之和计算强子像素的颜色值(例如亮度)，具体地，由输入图像数据中的第一个像素P0的红色亮度值R0和P0之前的像素(称之为P.)的红色亮度值(称之为R.)相加来得到显示面板上的第一列的红色强子像素的亮度值，然后，直接用输入图像数据中的第一个像素P0的绿色亮度值G0作为显示面板的第二列的绿色子像素的亮度值，接着，用输入图像数据中的第一个像素P0的蓝色亮度值B0和第二个像素P1的蓝色亮度值B1相加来得到显示面板的第三列的蓝色强子像素的亮度值，接下来用第二个像素P1的红色亮度值R1作为显示面板的第四列的红色子像素的亮度值，用第二个像素P1的绿色亮度值G1和第三个像素P2的绿色亮度值G2相加为显示面板的第五列的绿色子像素的亮度值，用第三个像素P2的蓝色亮度值B2作为显示面板的第五列的蓝色子像素的亮度值，用第三个像素P2的红色亮度值R2和第四个像素P3的红色亮度值R3相加作为第六列的红色子像素的亮度值，等等；图17(d)示出了将图17(c)计算后的值发送到陶氏三元像素显示屏(TTPD)上显示。
图18(a)-(d)示出了根据本发明实施例的陶氏八元像素显示屏(TOPD)从图像数据到面板显示的原理图，其中图18(a)示出了具有多个像素的一幅彩色图像的部分输入图像数据；其中Pij表示第i行第列的像素的部分输入图像数据，i和j为大于等于0的整数；图18(b)具体示出图18(a)所示图像中的6个像素P0-P5的颜色值，分别为(R0,G0,B0),…,(R5,G5,B5)；其颜色值为(R0,G0,B0),…,(R5,G5,B5)；图18(c)示出了根据图11(b)中子像素的 排列方式，从相邻的、颜色相同的、两个子像素的颜色数值(例如亮度)之和计算强子像素的颜色值(例如亮度)，具体地，由输入图像数据中的第一个像素P0的红色亮度值R0和P0之前的像素(称之为P.)的红色亮度值(称之为R.)相加来得到显示面板上的第一列的红色强子像素的亮度值，然后，直接用输入图像数据中的第一个像素P0的绿色亮度值G0作为显示面板的第二列的绿色子像素的亮度值。接着，用输入图像数据中的第二个像素P1的蓝色亮度值B1作为显示面板的第三列的蓝色子像素的亮度值，用输入图像数据中的第二个像素P1的白色亮度值W1和第三个像素P2的白色亮度值W2相加来得到显示面板的第四列的白色强子像素的亮度值。接下来用第三个像素P2的红色亮度值R2作为显示面板的第五列的红色子像素的亮度值，用第四个像素P3的绿色亮度值G3作为显示面板的第六列的绿色子像素的亮度值，用第四个像素P3的蓝色亮度值B3和第五个像素P4的蓝色亮度值B4相加为显示面板的第七列的蓝色子像素的亮度值，等等；图18(d)示出了将图18(c)计算后的值发送到陶氏八元像素显示屏(TOPD)上显示。
上面以陶氏三元像素显示屏和陶氏八元像素显示屏为例，说明了本发明实施例的基于输入图像数据、根据显示屏中子像素的排列方式来渲染子像素的方法。该实施例的显示屏和渲染方法的结合使得显示装置具有高像素密度、低能耗、强颜色还原能力的优势。
根据本发明再一实施例，提供了一种显示装置，可以包括：显示面板，由若干个像素排列组成，每个像素由至少二种不同颜色的子像素排列在一行中组成，其中同一行内的相邻像素之间或相邻的像素对之间的相邻子像素的颜色相同；以及驱动电路，用于向显示面板的每一个子像素发送信号。
在一个示例中，上述实施例的显示装置中的同一行内的相邻像素的同色相邻子像素被选择性地合并为一个强子像素，该强子像素内部不存在黑色间隔，且其亮度大于被合并的原同色子像素的任一个的亮度。
根据本发明的一个实施例，提供了一种显示装置的子像素的渲染方法，该显示装置包括：显示面板，由若干个像素排列组成，每个像素由不同颜色的子像素排列在一行中组成，其中同一行内的相邻像素之间或相邻的像素对之间的相邻子像素的颜色相同，其中同一行内的相邻像素的同色相邻子像素 被选择性地合并为一个强子像素，该强子像素内部不存在黑色间隔，且其亮度大于被合并的原同色子像素的任一个的亮度，显示面板中的子像素的排列方式定义了输出显示格式。该子像素的渲染方法包括：接收第一格式的输入图像数据，以供以所述输出显示格式使得显示装置渲染；基于输入图像数据执行子像素渲染操作，以产生所述显示面板上每个子像素的亮度值；向显示面板的每一个子像素发送信号，其中对强子像素进行渲染包括：获得输入图像数据的相关联的两个像素的每个的颜色数值中与该强子像素的颜色对应的颜色数值；将该两个对应的颜色数值相加结果作为该强子像素的颜色数值。
以上已经描述了本发明的各实施例，上述说明是示例性的，并非穷尽性的，并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说各种组合、次组合、修改和变更都是显而易见的。因此，本发明的保护范围应该以权利要求的保护范围为准。
