在示例性实施例中,第二晶体管和第三晶体管可在不同的时间导通。
在示例性实施例中,耦接至第一像素的第一数据线可在第一帧和第二帧中供给数据电压,并且耦接至第二像素的第二数据线和耦接至第三像素的第三数据线可仅在第一帧中供给数据电压。

图6是示出根据本发明的显示装置的驱动方法的示例性实施例的图。
具体实施方式
在下文中,参照附图详细描述了示例性实施例使得本领域技术人员可易于实施本发明。本发明可以以各种不同的方式实施并且不限于说明书中描述的示例性实施例。
将理解的是,当一个元件被称作“在”另一元件“上”时,该元件可直接在另一元件上,或者其间可存在中间元件。相比之下,当一个元件被称作“直接在”另一元件“上”时,不存在中间元件。
将理解的是,虽然在文中可使用术语“第一”、“第二”、“第三”等来描述各种元件、部件、区域、层和/或部分,但这些元件、部件、区域、层和/或部分不应当受这些术语的限制。这些术语仅用于将一个元件、部件、区域、层或部分与另一元件、部件、区域、层或部分区分开。因此,下面讨论的“第一元件”、“第一部件”、“第一区域”、“第一层”或“第一部分”在不脱离文中的教导的情况下可以被称为第二元件、第二部件、第二区域、第二层或第二部分。
文中使用的术语仅用于描述特定实施例的目的而不是为了限制的目的。如文中所使用的,除非上下文另外明确地指出,否则单数形式“一个”、“一种(者)”、和“该(所述)”旨在包括复数形式,包括“至少一个(种/者)”。“或”意味着“和/或”。如文中所使用的,术语“和/或”包括一个或多个所列相关项的任意组合和所有组合。还将理解的是,当在本说明书中使用术语“包括”和/或“包含”及其各种变型时,说明存在所陈述的特征、区域、整体、步骤、操作、元件和/或部件,但是不排除存在或附加一个或多个其它特征、区域、整体、步骤、操作、元件、部件和/或它们的组。
此外,在文中可以使用诸如“在……下面”或“下部”以及“在……上面”或“上部”的相对术语来描述如图中示出的一个元件与另一元件的关系。将理解的是,除了图中描绘的方位之外,相对术语旨在包括装置的不同方位。在示例性实施例中,当在一个附图中的装置被翻转时,被描述为在其它元件“下”侧的元件将然后被定位为在其它元件“上”侧。因此,根据图中的具体方位,示例性术语“在……下面”可以包括“在……下面”和“在……上面”两种方位。类似地,当在一个附图中的装置被翻转时,被描述为“在”其它元件“下方”或“之下”的元件将然后被定位为“在”其它元件“上方”。因此,示例性术语“在……下方”或“在……之下”可以包括“上方”和“下方””两种方位。
除非另外限定,否则文中使用的所有术语(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所通常理解的相同的含义。还将理解的是,除非在文中明确地如此定义,否则诸如在通用词典中定义的那些术语的术语应当被解释为具有与它们在现有技术和本发明的上下文中的含义相一致的含义,且不应以理想化或过于正式的含义来解释。
在文中参照作为理想化实施例的示意图的剖视图来描述示例性实施例。如此,将预料到例如由制造技术和/或公差导致的视图的形状的变化。因此,文中描述的实施例不应当被解释为限于如文中示出的区域的特定形状,而是包括例如由制造导致的形状上的变化。在示例性实施例中,示出或描述为平坦的区域通常可具有粗糙的和/或非线性的特征。而且,示出的尖角可以被圆化。因此,图中示出的区域在本质上是示意性的,并且它们的形状并非意图示出区域的精确形状,且并非意图限制权利要求的范围。
将省略与描述无关的部分以清楚地描述本发明,并且在整个说明书中,将由相同的附图标记来指定相同或类似的构成元件。因此,相同的附图标记可用于不同的图中以识别相同或类似的元件。
此外,图中示出的每个部件的尺寸和厚度是为了更好理解和易于说明而任意示出的,但是本发明不限于此。为了清除地表达,夸大了若干部分和区域的厚度。
图1是示出根据本发明的示例性实施例的显示装置的图。
参照图1,根据本发明的示例性实施例的显示装置10包括时序控制器110、扫描驱动器120、数据驱动器130、电源单元140、发射控制器150、多个像素PX1、PX2、PX3、…、以及滤色器层CFL。
时序控制器110使用从外部应用处理器(“AP”)等接收的数据使能信号、垂直同步信号、水平同步信号、图像信号等将经校正以适于数据驱动器130的规格的图像信号DATA发送到数据驱动器130,并且将对应的控制信号DCS和SCS分别发送到数据驱动器130和扫描驱动器120。

发射控制器150控制多个像素PX1、PX2、PX3、…的发射时间,并且提供第一发射控制线和第二发射控制线。在以下附图(例如,图3)中,为便于描述,发射控制器150配置为使得多个像素行的发射周期相同的同步发射型发射控制器。然而,在另一示例性实施例中,发射控制器150可配置为使得多个像素行的发射周期依次开始的顺序发射型发射控制器。
图2是示出根据本发明的示例性实施例的像素和滤色器层的图。
参照图2,示出了对应于图1的线I-I’的像素PX1、PX2、PX3和滤色器层CFL的部分。

在示例性实施例中,例如,第一滤色器CF1可以是白色滤色器,第二滤色器CF2可以是红色滤色器,并且第三滤色器CF3可以是绿色滤色器。
在示例性实施例中,滤色器层CFL还可包括介于第一滤色器CF1和第二滤色器CF2之间的黑矩阵BM1以防止混色。此外,滤色器层CFL还可包括介于第二滤色器CF2和第三滤色器CF3之间的黑矩阵BM2以防止混色。
在一些示例性实施例中,用于防止混色的黑矩阵还可被包括在各个像素PX1、PX2和PX3之间。
在示例性实施例中,随着LED YLD1、LED YLD2和LED YLD3在第一帧中发光,可表示基于黄色的多个颜色,并且随着LED BLD1在不同于第一帧的第二帧中发光,可表示蓝色。表示基于黄色的多个颜色的帧和表示蓝色的帧交替显示在显示装置10中,以便用户观察到的最终图像可具有自然色。
如将参照以下附图(例如,图3)在后面描述的,根据该示例性实施例的显示装置10不包括任何液晶层,并且包括可针对每个像素独立驱动的LED,以便当使用白色滤色器时可防止色彩故障。
此外,在第一像素PX1中,使用一个像素电路以时分方式驱动两个LED,以便有利于确保显示装置10的分辨率。
图3是示出根据本发明的示例性实施例的第一像素的图。
参照图3,根据本发明的示例性实施例的第一像素PX1包括:多个晶体管T11、T12、T13和T14、存储电容器Cst11以及两个LED YLD1和LED BLD1。
在下文中,将晶体管示出为P型晶体管,但本领域技术人员可使用N型晶体管设计出执行相同功能的像素电路。
晶体管T11的一端耦接至电源线QVDD,晶体管T11的另一端耦接至晶体管T13的一端和晶体管T14的一端,并且晶体管T11的栅电极耦接至晶体管T12的另一端。

晶体管T13的一端耦接至晶体管T11的另一端,晶体管T13的另一端耦接至LEDYLD1的阳极,并且晶体管T13的栅电极耦接至第一发射控制线EMa。第一发射控制线EMa可从发射控制器150延伸以将第一发射控制信号供给到第一像素PX1。

更具体地,LED YLD1的阳极可耦接至LED BLD1的阴极,并且LED YLD1的阴极可耦接至LED BLD1的阳极。
此外,LED YLD1的阴极可耦接至电源线Qva,并且LED BLD1的阴极可耦接至电源线Qvb。

后面将参照图6描述第一像素PX1的驱动方法。

参照图4,根据本发明的示例性实施例的第二像素PX2包括多个晶体管T21、T22和T23、储电容器Cst21和LED YLD2。

后面将参照图6描述第二像素PX2的驱动方法。
图5是示出根据本发明的示例性实施例的第三像素的图。
参照图5,根据本发明的示例性实施例的第三像素PX3包括:多个晶体管T31、T32和T33、存储电容器Cst31和LED YLD3。

后面将参照图6描述第三像素PX3的驱动方法。
图6是示出根据本发明的示例性实施例的显示装置的驱动方法的图。
参照图6,示出了在示例性的四个帧中供给到各个像素PX1、PX2和PX3的信号值。
可将帧1和帧2结合以显示一个图像屏,并且可将帧3和帧4结合以显示下一个图像屏。在一些示例性实施例中,帧1可以是基于黄色的多个帧,并且帧2可以是蓝色帧。此外,帧3可以是基于黄色的多个帧,并且帧4可以是蓝色帧。
首先,在帧1中,电源线Qva耦接至低电压源,并且将低电压值QVCOM施加至电源线Qva。此时,电源线Qvb处于浮置状态。例如,电源线Qvb耦接至高阻抗Hi-Z。
接下来,通过扫描线Sn供给具有导通电平(低电平)的扫描信号。因此,晶体管T12、晶体管T22和晶体管T32处于导通状态,以便数据线D1、数据线D2和数据线D3分别与晶体管T11的栅电极、晶体管T21的栅电极和晶体管T32的栅电极彼此电耦接。
此时,将数据电压YD11供给至数据线D1,将数据电压YD21供给至数据线D2,并且将数据电压YD31供给至数据线D3。
因此,将各个数据电压YD11、YD21和YD31与电源线QVDD的高电压之间的差值分别写入存储电容器Cst11、Cst21和Cst31中。晶体管T11、晶体管T21和晶体管T31根据写入各个存储电容器Cst11、Cst21和Cst31的值来确定高电压源和低电压源之间的驱动电流路径的宽度。
接下来,通过第一发射控制线EMa供给导通电平(低电平)的第一发射控制信号。因此,晶体管T13、晶体管T23和晶体管T33处于导通状态,以便LED YLD1、LED YLD2和LED YLD3中的每个发光。此时,由于将具有截止电平(高电平)的第二发射控制信号供给至第二发射控制线EMb,所以晶体管T14处于截止状态,因此LED BLD1不发光。
接下来,在帧2中,电源线Qva处于浮置状态,并且电源线Qvb耦接至低电压源以被施加低电压值QVCOM。
接下来,通过扫描线Sn供给具有导通电平(低电平)的扫描信号。因此,晶体管T12、晶体管T22和晶体管T32处于导通状态,以便数据线D1、数据线D2和数据线D3分别与晶体管T11的栅电极、晶体管T21的栅电极和晶体管T31的栅电极彼此电耦接。
此时,将数据电压BD12供给至数据线D1,并且不将任何数据电压供给至数据线D2和数据线D3。
在一些示例性实施例中,可将数据电压供给至数据线D2和数据线D3。此时,由于在帧2中晶体管T23和晶体管T33根据具有高电平的第一发射控制信号而保持在截止状态,因此LED YLD2和LED YLD3中的每个都不发光。
将数据电压BD12和电源线QVDD的高电压之间的差值写入存储电容器Cst11中。晶体管T11根据写入存储电容器Cst11中的值来确定高电压源和低电压源之间的驱动电流路径的宽度。
接下来,通过第二发射控制线EMb供给具有导通电平(低电平)的第二发射控制信号。因此,晶体管T14处于导通状态,以便LED BLD1发光。此时,由于将具有截止电平(高电平)的第一发射控制信号供给到第一发射控制线EMa,因此LED YLD1、LED YLD2和LED YLD3中的每个都不发光。
因此,由于基于黄色的帧1和基于蓝色的帧2的结合,用户识别出具有自然色的图像屏。
帧3和帧4分别对应于帧1和帧2,因此,将省略重复描述。
在根据本发明的显示装置及其驱动方法中,即使当使用白色滤色器时仍可防止色彩故障现象。
文中已经公开了示例性实施例,且虽然采用了特定术语,但仅以一般性和描述性的含义而非为了限制目的来使用和解释这些术语。在一些情况下,对于自本申请的提交为止的本领域普通技术人员而言明显的是,除非另外具体指明,否则与特定实施例相关地描述的特征、特性、和/或要素可以被单独使用,或者可以同与其他示例性实施例相关地描述的特征、特性、和/或要素相结合使用。因此,本领域技术人员将理解的是,在不脱离由权利要求阐述的本发明的精神和范围的情况下可进行形式和细节上的各种改变。
