Description
本申请要求于2016年11月30日提交的韩国专利申请No.10-2016-0161279的优先权,通过引用将其如同在本文中完全阐述的那样并入本文。
技术领域
本发明涉及包括设置在显示面板上的扫描驱动器的主级的显示装置。
背景技术
通常,诸如监视器、电视机、膝上型计算机、数码摄像机等电子设备包括用于实现图像的显示装置。例如,显示装置可以包括液晶显示器和有机发光二极管显示器。
显示装置可以包括显示面板,显示面板包括在其中实质上实现图像的显示区域。显示装置还可以包括用于向显示区域提供数据信号的数据驱动器和用于顺序地提供扫描信号的扫描驱动器。扫描驱动器可以是面板内栅极(GIP)型。例如,扫描驱动器可以包括设置在显示面板上并且位于显示区域之外的主级。
主级可以通过扫描线连接到显示区域。每个主级可以接收来自其先前主级之一的信号和其后续主级之一的信号来进行操作。例如,第n主级可以接收来自第(n-3)主级的开始信号并且接收来自第(n+3)主级的重置信号。例如,扫描驱动器可以包括用于将开始信号提供给相对来说位于前侧的主级的至少一个顶部虚设级以及用于将重置信号提供给相对来说位于后侧的主级的至少一个底部虚设级。
集成型扫描驱动器的每个主级和至少一个虚设级可以由薄膜晶体管构成。例如,集成型扫描驱动器的主级和虚设级中的每个可以包括多个薄膜晶体管。
然而,通过反复导通和关断而使薄膜晶体管的阈值电压偏移。例如,当阈值电压偏移为负值时,构成集成型扫描驱动器的主级和虚设级的薄膜晶体管可能不能稳定地保持在关断状态。因此,在包括集成型扫描驱动器的显示装置中,由于Q节点的纹波,可能在主级中产生多个输出。
发明内容
因此,本发明涉及一种具有位于显示面板上的扫描驱动器的主级的显示装置,其基本消除了由于相关技术的限制和缺点而引起的一个或多个问题。
本发明的一个目的是提供一种显示装置,其能够延迟由主级中的Q节点的纹波产生的多个输出。
本发明的另一个目的是提供一种显示装置,其能够减小用于向主级提供开始信号或重置信号的至少一个虚设级中的Q节点的纹波。虚设级可以是指未被扫面线连接到显示区域的级。

虚设线可以被定位成与显示区域和数据驱动器之间的扫描线平行。
虚设线的长度可以不同于扫描线的长度。
虚设线可以包括位于数据线之间的端部。
虚设级可以包括用于向主级提供开始信号的至少一个顶部虚设级和用于向主级提供重置信号的至少一个底部虚设级。虚设线可以包括连接到顶部虚设级的顶部虚设线和连接到底部虚设级的底部虚设线。显示区域可以位于顶部虚设线和底部虚设线之间。
顶部虚设线和底部虚设线可以被定位成与扫描线平行。数据线可以完全贯穿显示区域。
在本发明的另一方面,显示装置包括显示面板,显示面板包括显示区域、通过数据线连接到显示区域的数据驱动器、通过第一扫描线连接到显示区域的第一扫描驱动器、以及通过第二扫描线连接到显示区域的第二扫描驱动器。第一扫描驱动器和第二扫描驱动器位于显示面板上。第二扫描驱动器与第一扫描驱动器间隔开。至少一个底部虚设线位于显示面板的显示区域之外。底部虚设线连接第一扫描驱动器和第二扫描驱动器。
显示区域可以位于数据驱动器、第一扫描驱动器、第二扫描驱动器和底部虚设线之间。

(实施方式)
图1是示意性地示出根据本发明的实施方式的显示装置的图。
参考图1,根据本发明的实施方式的显示装置可以包括显示面板100、定时控制器200、数据驱动器300、电平移位器410、第一扫描驱动器421和第二扫描驱动器422。
显示面板100可以包括在其中实现图像的显示区域110。显示区域110可以包括根据从数据驱动器300、第一扫描驱动器421和第二扫描驱动器422提供的信号而驱动的像素区域。在每个像素区域中,可以布置有透过性被所提供的信号改变的元件或亮度被所提供的信号改变的发光元件。例如,根据本发明的实施方式的显示装置可以是包括位于显示区域110中的多个有机发光元件的有机发光显示装置。
定时控制器200可以生成和提供用于控制数据驱动器300和电平移位器410的操作定时的定时控制信号。例如,定时控制器200可以基于定时信号如垂直同步信号、水平同步信号、数据使能信号和点时钟来生成定时控制信号。例如,定时控制器200可以通过连接到图像板的低电压差分信号(LVDS)或最小化传输差分信号(TMDS)接口接收电路接收定时信号如垂直同步信号、水平同步信号、数据使能信号和点时钟等。
数据驱动器300可以向显示面板100的显示区域110提供数据信号。显示区域110和数据驱动器300可以被数据线DL1至DLk连接。显示区域110可以通过数据线DL1至DLk从数据驱动器300接收数据信号。
数据驱动器300可以包括多个源极驱动IC。每个源极驱动IC可以被从定时控制器200接收的定时控制信号控制。例如,定时控制器200可以向每个源极驱动IC提供数字视频数据和源极定时控制信号。每个源极驱动IC可以根据源极定时控制信号将数字视频数据转换为伽玛电压并生成数据信号。
数据驱动器300可以被设置在显示面板100之外。例如,数据驱动器300可以通过玻璃上的芯片(COF)或带自动接合(TAB)方法来连接到位于显示面板100上的数据线DL1至DLk。
电平移位器410可以在定时控制器200的控制下使时钟信号、重置时钟信号和开始信号的电平移位,并且将具有经移位的电平的信号提供给第一扫描驱动器421和第二扫描驱动器422。第一扫描驱动器421和第二扫描驱动器422可以通过电平移位器410将扫描信号顺序地提供给显示区域110。
根据本发明的实施方式的显示装置被描述为电平移位器410位于显示面板100之外。然而,根据本发明的另一实施方式的显示装置可以包括设置在显示面板100上的电平移位器410。
第一扫描驱动器421和第二扫描驱动器422可以向显示面板100的显示区域110提供扫描信号。显示区域110和第一扫描驱动器421可以被第一扫描线LGL1至LGLn连接。显示区域110和第二扫描驱动器422可以被第二扫描线RGL1至RGLn连接。显示区域110可以通过第一扫描线LGL1至LGLn和第二扫描线RGL1至RGLn顺序地接收扫描信号。例如,显示区域110可以按以下顺序从扫描线接收扫描信号:LGL1、RGL1、LGL2、RGL2、……、LGLn、RGLn。又例如,显示区域110可以按以下顺序从扫描线接收扫描信号:LGL1、LGL2、……、LGLn、RGL1、RGL2、……、RGLn。然而,接收扫描信号的顺序不限于以上示例。
第一扫描驱动器421和第二扫描驱动器422可以设置在显示面板100上。第一扫描驱动器421和第二扫描驱动器422可以位于显示区域110之外。扫描驱动器422可以与第一扫描驱动器421间隔开。例如,显示区域110可以设置在第一扫描驱动器421和第二扫描驱动器422之间。
在显示区域110中,数据线DL1至DLk可以与第一扫描线LGL1至LGLn或第二扫描线RGL1至RGLn交叉。第二扫描线RGL1至RGLn可以与第一扫描线LGL1至LGLn并排地配置。例如,第二扫描线RGL1至RGLn的数量可以等于第一扫描线LGL1至LGLn的数量。第二扫描驱动器422的结构可以与第一扫描驱动器421的结构相同。第一扫描线LGL1至LGLn的数量和第二扫描线数RGL1至RGLn的数量可以不同于数据线DL1至DLk的数量。
在根据本发明的实施方式的显示装置中,第二扫描线RGL1至RGLn与第一扫描线LGL1至LGLn分离开。然而,在根据本发明的另一实施方式的显示装置中,第二扫描线RGL1至RGLn可以连接到与相应的第二扫描线RGL1至RGLn并排地设置的第一扫描线LGL1至LGLn。例如,在根据本发明的另一实施方式的显示装置中,第一扫描驱动器421和第二扫描驱动器422可以被第一扫描线LGL1至LGLn和第二扫描线RGL1至RGLn连接。
图2是示意性示出根据本发明的实施方式的显示装置的扫描驱动器421的图。
参照图1和图2,根据本发明的实施方式的显示装置的第一扫描驱动器421可以包括由顶部虚设级TDT1至TDTm、主级ST1至STn和底部虚设级BDT1至BDTm构成的级TDT1至TDTm、ST1至STn和BDT1至BDTm。
主级ST1至STn可以设置在顶部虚设级TDT1至TDTm和底部虚设级BDT1至BDTm之间。主级ST1至STn中的每个可以连接到第一扫描线LGL1至LGLn之一。例如,主级ST1至STn的数量可以等于第一扫描线LGL1至LGLn的数量。
主级ST1至STn可以接收来自在前的级TDT1至TDTm、ST1至STn和BDT1至BDTm之一以及在后的级TDT1至TDTm、ST1至STn和BDT1至BDTm之一的信号以进行操作。例如,主级ST1至STn可以包括连接到扫描线LGL1至LGLn的第一输出端子和通过载波线C1至Cn+2m连接到其他级TDT1至TDTm、ST1至STn和BDT1至BDTm的第二输出端子。
描述了根据本发明的实施方式的显示装置,主级ST1至STn中的每个包括两个输出端子。然而,在根据本发明的另一实施方式的显示装置中,主级ST1至STn中的每个可以包括一个输出端子。例如,根据本发明的另一实施方式的显示装置的载波线C1至Cn+2m可以连接到相应的扫描线LGL1至LGLn。
主级ST1至STn中的相对位于前侧的一些主级ST1至STn可以接收来自顶部虚设级TDT1至TDTm之一的信号。主级ST1至STn中的相对位于后侧的一些主级ST1至STn可以接收来自底部虚设级BDT1至BDTm之一的信号。底部虚设级BDT1至BDTm的数量可以等于顶部虚设级TDT1至TDTm的数量。顶部虚设级TDT1至TDTm的数量和底部虚设级BDT1至BDTm的数量可以与主级ST1至STn的数量不同。
顶部虚设级TDT1至TDTm和底部虚设级BDT1至BDTm可以具有与主级ST1至STn相同的结构。例如,顶部虚设级TDT1至TDTm和底部虚设级BDT1至BDTm中的每个可以包括两个输出端子。扫描线LGL1至LGLn可以不连接到顶部虚设级TDT1至TDTm的输出端子和底部虚设级BDT1至BDTm的输出端子。
顶部虚设线TDL1至TDLm可以连接到顶部虚设级TDT1至TDTm的未连接到载波线C1至Cn+2m的输出端子。底部虚设线BDL1至BDLm可以连接到底部虚设级BDT1至BDTm的未连接到载波线C1至Cn+2m的输出端子。
顶部虚设线TDL1至TDLm和底部虚设线BDL1至BDLm可以布置在显示面板100上。顶部虚设线TDL1至TDLm和底部虚设线BDL1至BDLm可位于显示面板100之外。例如,显示区域110可以设置在顶部虚设线TDL1至TDLm和底部虚设线BDL1至BDLm之间。
顶部虚设线TDL1至TDLm和底部虚设线BDL1至BDLm可以被定位成与第一扫描线LGL1至LGLn和第二扫描线RGL1至RGLn平行。顶部虚设线TDL1至TDLm可以设置在显示区域110和数据驱动器300之间。顶部虚设线TDL1至TDLm可以与数据线DL1至DLk交叉。
顶部虚设线TDL1至TDLm和底部虚设线BDL1至BDLm可以在第一扫描驱动器421和第二扫描驱动器422之间进行连接。例如,第一扫描驱动器421的顶部虚设级TDT1至TDTm中的每个可以通过顶部虚设线TDL1至TDLm之一连接到第二扫描驱动器422的对应的顶部虚设级TDT1至TDTm。例如,第一扫描驱动器421的底部虚设级BDT1至BDTm可以分别通过底部虚设线BDL1至BDLm之一连接到第二扫描驱动器422的底部虚设级BDT1至BDTm。
在根据本发明的实施方式的显示装置中,载波线C1至Cn+2m以及虚设线TDL1至TDLm和BDL1至BDLm可以连接到虚设级TDT1至TDTm及BDT1到BDTm的输出端子。虚设线TDL1至TDLm及BDL1至BDLm可以连接在两个扫描驱动器421和422的相应的虚设级TDT1至TDTm及BDT1至BDTm之间。此外,顶部虚设级TDT1至TDTm的虚设线TDL1至TDLm可以与数据线DL1至DLk交叉,使得顶部虚设级TDT1至TDTm可具有寄生电容。因而,在根据本发明的实施方式的显示装置中,可以将虚设线TDL1至TDLm及BDL1至BDLm的负载施加至虚设级TDT1至TDTm及BDT1至BDTm的输出端子。
图3是示意性地示出根据本发明的实施方式的显示装置的第i级的图。图4是示出根据本发明的实施方式的显示装置的第i级的操作波形的图。在此,第i级可以是顶部虚设级TDT1至TDTm、主级ST1至STn和底部虚设级BDT1至BDTm之一。
参照图1至图4,将描述根据本发明的实施方式的每个级的操作。首先,当通过连接到第(i-3)级的第(i-3)载波线Ci-3施加高电平信号时,Q节点充电晶体管T1和T1A可以导通,使得可以对Q节点充电。此时,由于连接到与载波线Ci连接的第一输出端子和与扫描线或虚设线连接的第二输出端子SCi的上拉晶体管T6和T6cr被经充电的Q节点导通,但是被施加到上拉晶体管T6和T6cr的源极端子的时钟信号SCCLK和CRCLK具有低电平,级的输出端子可以输出低电平信号。此外,即使当通过第(i-3)载波线Ci-3施加的信号变为低电平时,由于通过连接到第(i+3)载波级的第(i+3)载波线Ci+3施加的信号保持在低电平并且第一低电压GVSS1通过充电的Q节点被提供给Qb节点,Q节点放电晶体管T3、T3A、T3n和T3nA都被关断,并且可以维持Q节点的充电状态。
在这种状态下,当高电平时钟信号SCCLK和CRCLK被分别施加到上拉晶体管T6和T6cr的源极端子时,可以提升Q节点的电压,并且级的输出端子可以输出高电平载波信号和扫描信号。
随后,当通过第(i+3)载波线Ci+3施加高电平信号时,Q节点放电晶体管T3n和T3nA可以导通,使得Q节点可以连接到第二低电压端子GVSS2,由此Q节点可以被放电。此时,上拉晶体管T6和T6cr可以被经放电的Q节点关断,并且Qb节点可以连接高电压端子GVDD以进行充电。下拉晶体管T7和T7cr可以被经充电的Qb节点导通,因此输出端子可以连接到低电压端子GVSS0和GVSS2。因此,即使当高电平时钟信号SCCLK和CRCLK被施加到其他级的上拉晶体管T6和T6cr的源极端子时,也可以通过相应级的输出端子输出低电平信号。
图5是示出其中负载被施加至输出端子的虚设级G1以及其中负载未施加至输出端子的虚设级G2中的Q节点的纹波随着时间推移的曲线图。
参照图5,可以看出,在其中负载施加到输出端子的虚设级G1的Q节点中生成相对低电平的纹波。也就是说,在根据本发明的实施方式的显示装置中,由于负载通过虚设线被施加到虚设级的输出端子,所以可以减小在虚设级的Q节点中生成的纹波。
当虚设级的Q节点中生成的纹波的电平减小时,可以减小上拉晶体管或下拉晶体管所产生的漏电流。因此,可以通过虚设级来减小在主级的Q节点中积累的电流。因而,在主级的Q节点中产生多个输出之前可以积累相对大的电流。
因此,根据本发明的实施方式的显示装置可以减小在虚设级的Q节点中产生的纹波的电平,使得可以增加在主级的Q节点中积累的电流裕度,由此延迟由于主级的Q节点中产生的纹波而导致的多个输出。
描述了根据本发明的实施方式的显示装置,其中位于显示区域110和数据驱动器300之间并与数据线DL1至DLk交叉的顶部虚设线TDL1至TDLm连接第一扫描驱动器421和第二扫描驱动器422。然而,如图6所示,根据本发明的另一实施方式的显示装置可以包括连接到第一扫描驱动器421并与数据线DL1至DLk中的至少之一交叉的第一顶部虚设线LDL1至LDLm,以及连接到第二扫描驱动器422并与数据线DL1至DLk中的至少之一交叉的第二顶部虚设线RDL1至RDLm。第一顶部虚设线LDL1至LDLm的长度和第二顶部虚设线RDL1至RDLm的长度可以小于底部虚设线BDL1至BDLm的长度。第二顶部虚设线RDL1至RDLm可以被定位成与第一顶部虚设线LDL1至LDLm并排。例如,第二顶部虚设线RDL1至RDLm中的每个的端部可以面对第一顶部虚设线LDL1至LDLm中的每个的端部。第一顶部虚设线LDL1至LDLm的端部和第二顶部虚设线RDL1至RDLm的端部可以设置在数据线DL1至DLk中相邻的两个数据线之间。
根据本发明的该实施方式的显示装置可以具有由与第一顶部虚设线LDL1至LDLm和第二顶部虚设线RDL1至RDLm交叉的数据线DL1至DLk中的至少之一引起的寄生电容。因此,在根据本发明的另一实施方式的显示装置中,不连接第一扫描驱动器421和第二扫描驱动器422的第一顶部虚设线LDL1至LDLm和第二顶部虚设线RDL1至RDLm的负载可以施加到第一扫描驱动器421和第二扫描驱动器422的顶部虚设级的输出端子。因而,在根据本发明的另一实施方式的显示装置中,可以在考虑其他信号线的情况下布置位于显示区域110和数据驱动器300之间的虚设线LDL1至LDLm及RDL1至RDLm。
描述了根据本发明的实施方式的显示装置,其包括两个扫描驱动器421和422。然而,如图7所示,根据本发明的另一实施方式的显示装置可以包括一个集成型扫描驱动器420。在根据本发明的另一实施方式的显示装置中,底部虚设线BDL1至BDLm可以与数据线DL1至DLk交叉。例如,根据本发明的另一实施方式的显示装置可以包括完全贯穿显示区域110的数据线DL1至DLk。
根据本发明的实施方式的显示装置可以减小集成型扫描驱动器的至少一个虚设级中的Q节点的纹波。因此,在根据本发明的实施方式的显示装置中,使用虚设级的输出信号作为开始信号或重置信号,可以在主级中延迟由Q节点的纹波引起的多个输出。因此,在根据本发明的实施方式的显示装置中,可以提高集成型扫描驱动器的可靠性。
需要指出,诸如“顶部虚设级”、“底部虚设级”、“顶部虚设线”、“底部虚设线”等短语中的表述顶部和底部是用于区分上述单元关于显示区域的相对位置,而不意在限制这些单元在真实空间中的位置。例如,在真实空间中,顶部虚设级不一定被布置在底部虚设级的上方。
