图1示意性地图示了根据本公开实施例的显示装置10的框图。参照图1,显示装置10包括:信号控制器100、扫描驱动器200、数据驱动器300和显示面板400。
信号控制器100接收从外部装置输入的同步信号和视频信号R、G 和B。视频信号R、G和B包含多个像素PX中每个的亮度信息,其中亮度具有设置数(例如,预定数)的灰度(或者灰度等级),例如,1024(=2 10)、256(=2 8)、或者64(=2 6)灰度。同步信号包括水平同步信号Hsync、垂直同步信号Vsync、主时钟信号MCLK以及数据使能信号DE。
信号控制器100根据视频信号R、G和B、水平同步信号Hsync、垂直同步信号Vsync、数据使能信号DE以及主时钟信号MCLK生成第一驱动控制信号CONT1、第二驱动控制信号CONT2和图像数据信号DAT。信号控制器100根据垂直同步信号Vsync将视频信号R、G和B划分为帧的单位,并且根据水平同步信号Hsync将视频信号R、G和B划分为数据行的单位,以生成图像数据信号DAT。信号控制器100将图像数据信号DAT和第二驱动控制信号CONT2传送到数据驱动器300。
显示面板400包括有基本以矩阵形式排列的像素PX。像素PX的排列方式将在下文参照图2-5进行详细描述。在显示面板400中,多个基本平行的扫描线S1至Sn沿着行方向延伸,并且多个基本平行的数据线D1至Dm沿着列方向延伸。扫描线S1至Sn和数据线D1至Dm被耦合到像素PX。在一些实施例中,显示面板400可以是有机发光显示面板。在非限制性示例中,有机发光显示面板可以包括其上形成有机发光像素结构的显示基板和面向显示基板的盖板。在一些实施例中,显示面板400可以是液晶显示面板。在非限制性示例中,液晶显示面板可以包括其上形成像素电极的第一基板、其上形成彩色滤光片(CF)的第二基板、以及设置在第一基板和第二基板之间的液晶层。彩色再现可以借助于彩色滤光片的过滤效应来实现。
扫描驱动器200被耦合到扫描线S1-Sn,并且根据第一驱动控制信号CONT1生成对应的多个扫描信号S[1]至S[n]。扫描驱动器200分别可以将栅极导通电压(gate-on voltage)的扫描信号S[1]-S[n]依次施加到扫描线S1-Sn。第一驱动控制信号CONT1包括帧起始信号FLM、第一时钟信号SCLK1和第二时钟信号SCLK2。帧起始信号FLM可以是生成用于显示单帧图像的第一扫描信号S[1]的信号。第一时钟信号SCLK1和第二时钟信号SCLK2是用于依次生成扫描信号S[1]-S[n]并施加到相应的扫描线S1-Sn的同步信号。
数据驱动器300被耦合到数据线D1-Dm,根据第二驱动控制信号CONT2采样和保持图像数据信号DAT,并且分别将多个数据信号D[1]至D[m]施加到数据线D1至Dm。通过根据被分别施加到扫描线S1至Sn的栅极导通电压的扫描信号S[1]至S[n]将具有设置电压范围(例如,预定电压范围)的数据信号D[1]至D[m]施加到数据线D1至Dm,数据驱动器300可以将数据编程到像素PX。
该显示装置10可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
图2示意性地图示了根据本公开实施例的像素排列结构的平面图。参照图2,该像素排列结构包括多个重复排列的子像素组20,每个子像素组包括子像素22、24、26。
第一子像素22发射第一颜色的光,第二子像素24发射第二颜色的光,并且第二子像素26发射第三颜色的光。作为示例,第一颜色可以为蓝色,第二颜色可以为红色,并且第三颜色可以为绿色。然而,本公开不限于此。更一般地,第一子像素22、第二子像素24和第三子像素26可以被配置成发射各不相同颜色的光。
在该实施例中,各子像素组20中的每个包括排列在四行和四列中的四个第一子像素22、四个第二子像素24和四个第三子像素26。具体地,如图2所示,子像素组20包括在第i列中(沿y轴的负方向)顺序排列的一个第一子像素22和两个第二子像素24(此处i为自然数)、在第i+1列中顺序排列的两个第三子像素26和一个第一子像素22、在第i+2列中顺序排列的两个第二子像素24和一个第一子像素22、以及在第i+3列中顺序排列的一个第一子像素22和两个第三像素26。更具体地,第i列中的两个第二子像素24中的每个与第i+1列中的第一子像素22的相应部分在行方向(在图2中为x轴的方向)上重叠,第i+1列中的两个第三子像素26中的每个与第i列中的第一子像素22的相应部分在行方向上重叠,第i+2列中的两个第二子像素24中的每个与第i+3列中的第一子像素22的相应部分在行方向上重叠,并且第i+3列中的两个第三子像素26中的每个与第i+2列中的第一子像素22的相应部分在行方向上重叠。换言之,每个第一子像素22被排列成跨相邻的两行分布。例如,如图示的,第i列和第i+3列中的第一子像素22跨第j行和第j+1行分布(此处j为自然数)使得它们与第j行和第j+1 行中的第二子像素24和第三子像素26重叠,并且第i+1列和第i+2列中的第一子像素22跨第j+2行和第j+3行分布使得它们与第j+2行和第j+3行中的第二子像素24和第三子像素26重叠。
借助于上面描述的像素排列,有可能获得高像素分辨率,因为例如与其中相同颜色的直接相邻的两个子像素否则被合并成单个子像素的方案相比,提供了相对较多的子像素。在子像素数目相对较多的情况下,还可以更容易地实现“像素借用”(pixel borrowing),从而促进子像素渲染。
将理解的是,图2中所示的像素排列是示例性的,因为各子像素22、24、26的属性,包括它们的相对尺寸和形状,在其他实施例中可以变化。
图3示意性地图示了图2的像素排列结构的变型的平面图。参照图3,该像素排列结构包括多个重复排列的子像素组30,每个子像素组包括子像素32、34、36。
类似于上面关于图2描述的实施例,各子像素组30中的每个包括排列在四行和四列中的四个第一子像素32、四个第二子像素34和四个第三子像素36。
本实施例不同于图2的实施例,在于第一子像素32与第一子像素22相比现在具有更大的宽度和更小的长度。在这种情况下,如图3所示,第i列中的两个第二子像素34中的每个的仅一部分与第i+1列中的第一子像素32的相应部分在行方向上重叠,第i+1列中的两个第三子像素36中的每个的仅一部分与第i列中的第一子像素32的相应部分在行方向上重叠,第i+2列中的两个第二子像素34中的每个的仅一部分与第i+3列中的第一子像素32的相应部分在行方向上重叠,并且第i+3列中的两个第三子像素36中的每个的仅一部分与第i+2列中的第一子像素32的相应部分在行方向上重叠。图3的实施例是示例性的;还设想了其他实施例。
图4示意性地图示了图2的像素排列结构的变型的平面图。参照图4,该像素排列结构包括多个重复排列的子像素组40,每个子像素组包括子像素42、44、46。
类似于上面关于图2描述的实施例,各子像素组40中的每个包括排列在四行和四列中的四个第一子像素42、四个第二子像素44和四个 第三子像素46。
本实施例不同于图2的实施例,在于第一子像素42现在具有六边形的形状。在这种情况下,如图4所示,第i列中的两个第二子像素44中的每个的仅一部分与第i+1列中的第一子像素42的相应部分在行方向上重叠,第i+1列中的两个第三子像素46中的每个的仅一部分与第i列中的第一子像素42的相应部分在行方向上重叠,第i+2列中的两个第二子像素44中的每个的仅一部分与第i+3列中的第一子像素42的相应部分在行方向上重叠,并且第i+3列中的两个第三子像素46中的每个的仅一部分与第i+2列中的第一子像素42的相应部分在行方向上重叠。图4的实施例是示例性的;还设想了其他实施例。例如,第一子像素42、第二子像素44和第三子像素46中的每个都可以具有其他多边形形状(例如三角形、四边形或五边形形状)、圆形形状、椭圆形状或其他形状。
图5示意性地图示了根据本公开另一实施例的像素排列结构的平面图。参照图5,该像素排列结构包括多个重复排列的子像素组50,每个子像素组包括子像素52、54、56,其中第一子像素52、第二子像素54和第三子像素56可以被配置成发射各不相同颜色的光。
在该实施例中,各子像素组50中的每个包括排列在四行和四列中的四个第一子像素52、四个第二子像素54和四个第三子像素56。具体地,如图5所示,子像素组50包括在第i列中顺序排列的第一子像素52、第二子像素54和第三子像素56(此处i为自然数)、在第i+1列中顺序排列的第二子像素54、第三子像素56和第一子像素52、在第i+2列中顺序排列的第二子像素54、第三子像素56和第一子像素52、以及在第i+3列中顺序排列的第一子像素52、第二子像素54和第三子像素56。更具体地,第i列中的第二子像素54和第三子像素56中的每个与第i+1列中的第一子像素52的相应部分在行方向上重叠,第i+1列中的第二子像素54和第三子像素56中的每个与第i列中的第一子像素52的相应部分在行方向上重叠,第i+2列中的第二子像素54和第三子像素56中的每个与第i+3列中的第一子像素52的相应部分在行方向上重叠,并且第i+3列中的第二子像素54和第三子像素56中的每个与第i+2列中的第一子像素52的相应部分在行方向上重叠。换言之,每个第一子像素52被排列成跨相邻的两行分布。例如,如图示的,第i 列和第i+3列中的第一子像素22跨第j行和第j+1行分布(此处j为自然数)使得它们与第j行中的第二子像素54和第j+1行中的第三子像素56重叠,并且第i+1列和第i+2列中的第一子像素52跨第j+2行和第j+3行分布使得它们与第j+2行中的第二子像素54和第j+3行中的第三子像素56重叠。
类似于上面结合图2描述的实施例,图5中示出的像素排列可以允许高像素分辨率,因为例如与其中相同颜色的直接相邻的两个子像素否则被合并成单个子像素的方案相比,提供了相对较多的子像素。
将理解的是,图5中所示的像素排列是示例性的,因为各子像素52、54、56的属性,包括它们的相对尺寸和形状,在其他实施例中可以变化。例如,类似于上面结合图3描述的实施例,子像素52、54、56可以具有不同于所图示的相对尺寸。又例如,类似于上面结合图4描述的实施例,子像素52、54、56可以具有不同于所图示的形状,诸如例如多边形、圆形或椭圆形状。
上面各实施例中描述的像素排列结构可以适用于有机发光显示面板和液晶显示面板。在有机发光显示面板的情况下,像素排列结构可以通过利用一组掩模板(例如,FMM)将有机发光材料蒸镀在基板上而形成。有机发光显示面板的品质(例如,像素分辨率)在很大程度上受掩模板的精度约束,因为掩模板由于其制造工艺(例如,蚀刻)的原因而通常具有低的精度。
图6A-6C示意性地图示了根据本公开实施例的一组掩模板的平面图。
参照图6A-6C,该组掩模板包括:包括限定多个第一开口62的第一金属框架60A的第一掩模板600A、包括限定多个第二开口64的第二金属框架60B的第二掩模板600B、以及包括限定多个第三开口66的第三金属框架60C的第三掩模板600C。将理解的是,如图6A-6C中的“Z”形剖面线(section lines)指示的,所示出的金属框架60A、60B、60C仅仅是它们的一部分,并且各第一、第二和第三开口62、64、66可以以恒定的图案重复排列。
在该实施例中,该组掩模板可以用来形成如图2中所示的像素排列结构。在第一掩模板600A中,每个第一开口62具有与该像素排列结构中的各第一子像素22中的相应一对直接相邻的第一子像素22连 同该相应一对第一子像素22之间的区域对应的形状。例如,图6A中最上面中间的第一开口62具有与图2中位于第i+3列和第i+4列且跨第j行和第j+1行分布的两个第一子像素22连同这两个子像素22之间的区域对应的形状。而且,在第一掩模板600A中,各第一开口62被排列成具有与该像素排列结构中的各对直接相邻的第一子像素22相同的图案。在形成第一子像素22的过程中,第一掩模板600A被定位使得各第一开口62分别与基板上用于各对直接相邻的第一子像素的各阳极区域对齐(每个阳极区域包括两个彼此分开的阳极,其中每个阳极对应于一个第一子像素),并且蒸发的有机发光材料穿过各个第一开口62并到达基板上的各阳极区域,从而形成单独的第一子像素22。
在第二掩模板600B中,每个第二开口64具有与该像素排列结构中的各第二子像素24中的相应一对直接相邻的第二子像素24连同该相应一对第二子像素24之间的区域对应的形状,并且各第二开口64被排列成具有与该像素排列结构中的各对直接相邻的第二子像素24相同的图案。在形成第二子像素24的过程中,第二掩模板600B被定位使得各第二开口64分别与基板上用于各对直接相邻的第二子像素的各阳极区域对齐(每个阳极区域包括两个彼此分开的阳极,其中每个阳极对应于一个第二子像素),并且蒸发的有机发光材料穿过各个第二开口64并到达基板上的各阳极区域,从而形成单独的第二子像素24。
在第三掩模板600C中,每个第三开口66具有与该像素排列结构中的各第三子像素26中的相应一对直接相邻的第三子像素26连同该相应一对第三子像素26之间的区域对应的形状,并且各第三开口66被排列成具有与该像素排列结构中的各对直接相邻的第三子像素26相同的图案。在形成第三子像素26的过程中,第三掩模板600C被定位使得各第三开口66分别与基板上用于各对直接相邻的第三子像素的各阳极区域对齐(每个阳极区域包括两个彼此分开的阳极,其中每个阳极对应于一个第三子像素),并且蒸发的有机发光材料穿过各个第三开口66并到达基板上的各阳极区域,从而形成单独的第三子像素26。
借助于这样的掩模板,每个开口可以用于形成两个(直接相邻的)子像素。例如与其中每个开口用于形成仅一个子像素的掩模板设计相比,这允许开口之间增大的间距(pitch)。换言之,这允许以较低精度的掩模板制作具有高像素分辨率的显示面板,从而有利于降低掩模 板的制作成本同时实现高像素分辨率。
将理解的是,图6A-6C中示出的该组掩模板是示例性的,并且可以根据期望的像素排列结构来设计其他掩模板。
图7A-7C示意性地图示了图6A-6C的该组掩模板的变型的平面图。
参照图7A-7C,该组掩模板包括:包括限定多个第一开口72的第一金属框架70A的第一掩模板700A、包括限定多个第二开口74的第二金属框架70B的第二掩模板700B、以及包括限定多个第三开口76的第三金属框架70C的第三掩模板700C。
在该实施例中,该组掩模板可以用来形成如图5中所示的像素排列结构。在第一掩模板700A中,每个第一开口72具有与该像素排列结构中的各第一子像素52中的相应一对直接相邻的第一子像素52连同该相应一对第一子像素52之间的区域对应的形状,并且各第一开口72被排列成具有与该像素排列结构中的各对直接相邻的第一子像素52相同的图案。
在第二掩模板700B中,每个第二开口74具有与该像素排列结构中的各第二子像素54中的相应一对直接相邻的第二子像素54连同该相应一对第二子像素54之间的区域对应的形状,并且各第二开口74被排列成具有与该像素排列结构中的各对直接相邻的第二子像素54相同的图案。
在第三掩模板700C中,每个第三开口76具有与该像素排列结构中的各第三子像素56中的相应一对直接相邻的第三子像素56连同该相应一对第三子像素56之间的区域对应的形状,并且各第三开口76被排列成具有与该像素排列结构中的各对直接相邻的第三子像素56相同的图案。
将理解的是,图7A-7C中示出的该组掩模板是示例性的,并且可以根据期望的像素排列结构来设计其他掩模板。
虽然前面的讨论包含若干特定的实现细节,但是这些不应解释为对任何公开或者可能要求保护的范围的限制,而应解释为对可能仅限于特定公开的特定实施例的特征的描述。在本说明书中不同的实施例中描述的特定特征也可以在单个实施例中以组合形式实现。与此相反,在单个实施例中描述的不同特征也可以在多个实施例中分别地或者以任何适当的子组合形式实现。此外,尽管前面可能将特征描述为以特 定组合起作用,甚至最初也被如此要求保护,但是来自所要求保护的组合中的一个或多个特征在某些情况下也可以从该组合中排除,并且该要求保护的组合可以被导向子组合或子组合的变型。
因此,应当理解,本公开的实施例并不限于所公开的特定实施例,并且修改和其他的实施例也意图被包含在所附权利要求书的范围内。尽管此处使用了特定术语,但是它们仅在通用和描述性意义上使用,而非为了限制的目的。
