Description

OLED显示装置及其光学补偿方法
本申请要求享有于2017年6月1日提交的韩国专利申请第10-2017-0068197号的权益,通过引用将该专利申请并入于此,如同在此完全阐述一样。
技术领域
本发明涉及一种有机发光二极管(OLED)显示装置,尤其涉及一种在显示模块与驱动器分离的显示装置中使用用于延长连接长度的额外线缆时,能够应对电压降的OLED显示装置及其光学补偿方法。
背景技术
有机发光二极管(OLED)显示装置在像素中包括作为自发光器件的OLED。OLED显示装置可具有比需要背光的液晶显示装置更低的功耗和更小的厚度。此外,OLED显示装置还具有宽视角和高响应速度。通过工艺技术发展为与液晶显示装置配套的大屏幕批量生产技术,OLED显示装置的市场正在扩大。
图1是图解一般OLED显示装置的像素结构的电路图。参照图1,显示面板的每个像素包括第一开关TFT ST1、第二开关TFT ST2、驱动TFT DT、电容器Cst和有机发光二极管OLED。
第一开关TFT ST1根据提供至栅极线GL的扫描信号scan(或栅极信号)进行开关,以将提供至数据线DL的数据电压Vdata提供至驱动TFT DT。
驱动TFT DT根据从第一开关晶体管ST1接收的数据电压Vdata进行开关,以控制从用于给电源线PL提供电力的第一驱动电源VDD流到有机发光二极管OLED的数据电流I_oled。
电容器Cst连接在驱动TFT DT的栅极端子和源极端子之间,以存储与提供至驱动TFT DT的栅极端子的数据电压Vdata对应的电压并利用存储的电压导通驱动TFT DT。
还包括形成在与栅极线GL相同方向上的感测信号线SL。第二开关TFT ST2根据施加至感测信号线SL的感测信号sense进行开关,以将提供至有机发光二极管OLED的数据电流I_oled提供至驱动IC的模拟-数字转换器(ADC)。
有机发光二极管OLED电连接在驱动TFT DT的源极端子与阴极电源VSS之间,以通过从驱动TFT DT接收的数据电流I_oled发光。
常规OLED显示装置中的每个像素根据数据电压Vdata利用驱动TFT DT的开关来控制从第一驱动电源VDD提供至有机发光二极管OLED的数据电流I_oled的级别,以使有机发光二极管OLED发光,由此显示预定图像。
然而,存在下述问题:根据TFT制造工艺的不均匀性,驱动TFT DT的阈值电压Vth或迁移率和有机发光二极管OLED的特性在像素之间不同。因此,在一般的OLED显示装置中,即使给每个像素的驱动TFT DT施加相同的数据电压Vdata,但由于有机发光二极管OLED中流动的电流的不同,不能实现均匀的图像质量。
为了改善由于制造工艺的偏差导致的驱动TFT DT的阈值电压Vth或迁移率和有机发光二极管OLED的特性的不均匀性,在OLED显示装置出货之前,感测所有像素的驱动TFTDT的阈值电压Vth或迁移率和有机发光二极管OLED的特性,以产生感测数据。
近来,如图2中所示,已开发了显示模块10和驱动器20分离的显示装置。为了减小显示模块10的厚度,驱动器20从显示模块10分离。
图3是示出像素的亮度测量单元的示图,亮度测量单元利用相机或光学扫描仪测量每个像素中的驱动TFT的特性偏差。如图3中所示,数据电压提供至显示面板的像素,以使像素的OLED发光,并且通过相机30拍摄每个像素的亮度。从由相机获得的图像测量每个像素的亮度的算法是已知的。可从由相机30获得的图像测量每个像素的亮度。相机30可在靠近显示面板的距离处在预定扫描方向上移动并且同时测量设置在像素阵列的一条线上的像素的亮度。
之后,使用亮度计40分析测量到的信息并且产生与所有像素P的驱动TFT DT的阈值电压Vth或迁移率和OLED的特性对应的补偿数据。之后,补偿数据存储在驱动器20中包括的时序控制器T-con的存储器EEPROM中。
在利用这种显示器时,除了作为用于将显示模块与驱动器连接的基本线缆的FPC线缆以外,还可使用延长线缆。就是说,显示模块与驱动器之间的距离可变得比基本设定距离更大。此时,由于线缆长度的增加,电阻增加并且发生电压降。为此,驱动器的存储器中存储的光学补偿数据是不适合的,因而未正确地执行光学补偿。
发明内容

时序控制器230给栅极驱动器120和数据驱动器130提供各种控制信号,以控制栅极驱动器120和数据驱动器130。时序控制器230根据每帧的时序开始扫描,将外部输入的输入图像数据转换为在数据驱动器130中使用的数据信号格式,以输出转换的图像数据,并且根据扫描来控制数据驱动。
栅极驱动器120在时序控制器230的控制下给多条栅极线按顺序提供ON电压或OFF电压的扫描信号,以按顺序驱动多条栅极线。栅极驱动器120可称为扫描驱动器。根据驱动方法,栅极驱动器120可位于显示面板100的一侧或两侧。此外,栅极驱动器120可包括一个或多个栅极驱动器集成电路。每个栅极驱动器集成电路可使用带式自动焊接(tapeautomated bonding,TAB)方法或玻上芯片(chip on glass,COG)方法连接至显示面板110的焊接焊盘,或者以面板内栅极(gate-in-panel,GIP)型实现以直接设置在显示面板110上。在一些情形中,栅极驱动器集成电路可进行集成并设置在显示面板110上。每个栅极驱动器集成电路可包括移位寄存器、电平转换器等。
当特定栅极线开启时,数据驱动器130将从时序控制器230接收的图像数据转换为模拟数据电压并且将经转换的模拟数据电压提供至数据线,由此驱动多条数据线。数据驱动器130可包括至少一个源极驱动器集成电路,以驱动多条数据线。每个源极驱动器集成电路可使用带式自动焊接(TAB)方法或玻上芯片(COG)方法连接至显示面板110的焊接焊盘,或者以面板内栅极(GIP)型实现以直接设置在显示面板110上。在一些情形中,源极驱动器集成电路可进行集成并设置在显示面板110上。可使用膜上芯片(COF)方法实现每个源极驱动器集成电路。在该情形中,每个源极驱动器集成电路的一端结合至至少一个源极印刷电路板,其另一端结合至显示面板110。每个源极驱动器集成电路可包括逻辑单元、数字-模拟转换器(DAC)、输出缓冲器等,逻辑单元包括移位寄存器、锁存电路等。在一些情形中,为了补偿子像素的特性(例如,驱动晶体管的阈值电压和迁移率、OLED的阈值电压、子像素的亮度等),可进一步包括用于感测子像素的特性的感测单元(传感器)。
连同输入图像数据一起,时序控制器230从外部(例如,主机系统)接收包括垂直同步信号Vsync、水平同步信号Hsync、输入数据使能(DE)信号和时钟信号CLK的各种时序信号。
时序控制器230不仅将从外部接收的输入图像数据转换为在数据驱动器130中使用的数据信号格式并输出经转换的图像数据,而且还接收包括垂直同步信号Vsync、水平同步信号Hsync、输入DE信号和时钟信号CLK的时序信号并产生各种控制信号和给栅极驱动器120和数据驱动器130输出该各种控制信号,以便控制栅极驱动器120和数据驱动器130。
例如,为了控制栅极驱动器120,时序控制器230输出包括栅极起始脉冲GSP、栅极移位时钟GSC、栅极输出使能(GOE)信号等的各种栅极控制信号GCS。栅极起始脉冲GSP控制一个或多个栅极驱动器集成电路的操作起始时序。栅极移位时钟GSC是公共地输入至一个或多个栅极驱动器集成电路以控制扫描信号(栅极脉冲)的移位时序的时钟信号。栅极输出使能(GOE)信号指定一个或多个栅极驱动器集成电路的时序信息。
为了控制数据驱动器130,时序控制器230输出包括源极起始脉冲SSP、源极采样时钟SSC、源极输出使能SOE信号等的各种数据控制信号DCS。源极起始脉冲SSP控制构成数据驱动器120的一个或多个源极驱动器集成电路的数据采样起始时序。源极采样时钟SSC是用于控制每个源极驱动器集成电路中数据的采样时序的时钟信号。源极输出使能(SOE)信号控制数据驱动器130的输出时序。
根据本发明的显示面板110上设置的多个子像素中的每一个可包括有机发光二极管(OLED)、用于驱动OLED的驱动晶体管(DRT)和存储电容器。
图5是图解根据本发明的OLED显示装置的光学补偿方法的流程图。
计算根据基本线缆的长度的光学补偿数据并将其存储在驱动器200的存储器220中。就是说,当使用FPC线缆作为基本线缆时,测量显示面板中的每个像素的亮度,并且计算光学补偿数据并将其存储在存储器中作为基本值(S501)。
将延长线缆连接至基本线缆。就是说,将作为延长线缆的线束线缆(harnesscable)连接至作为基本线缆的FPC线缆。计算考虑了由于延长线缆的连接而导致的电压降的光学补偿数据并将其存储在存储器中的不同地址处。此时,延长线缆的长度可以是各种不同的,并且与延长线缆的各种不同的长度对应地在存储器中存储各种光学补偿数据(S502)。
根据本发明的OLED显示装置可在驱动器的存储器中存储多个光学补偿数据的情况下出货。
为了使用其中显示模块100与驱动器200分离的OLED显示装置,在给驱动器200施加电力时自动执行根据本发明的OLED显示装置的光学补偿方法。
当给显示装置的驱动器200施加电力时,时序控制器230给线缆检查单元210发送控制信号,以检查是否使用延长线缆。就是说,确定显示模块100与驱动器200之间的信号传输线缆是基本线缆还是连接至基本线缆的延长线缆。作为检查是否使用延长线缆的方法,可使用各种方法。在下面的描述中,将描述检查是否使用延长线缆的方法的示例(S503)。
时序控制器230接收由线缆检查单元210检查的结果并根据该结果读取存储器220中存储的光学补偿数据。就是说,在确定未连接延长线缆时,读取由于使用基本线缆而导致的光学补偿数据。在确定使用延长线缆时,读取与由于使用延长线缆而导致的光学补偿数据对应的信息(S504)。
随后,时序控制器230应用读取的光学补偿数据并给显示模块100提供电力。就是说,选择性地应用由于基本线缆的延长而导致的光学补偿数据或考虑了由于延长的线缆长度而导致的电压降的光学补偿数据,以执行最佳的光学补偿。因此,即使在由于延长线缆的连接而发生电压降时,在显示模块的像素中仍实现最佳的亮度(S505)。
图6和图7是图解线缆检查单元的操作的示图。
首先,图6示出了使用基本线缆300连接显示模块100与驱动器200的情形。给基本线缆300添加引脚N+1,并且通过线缆检查单元210接收通过添加的引脚N+1传输的状态检查信号,由此向时序控制器传输表示使用基本线缆的信息。
接着,图7示出了其中延长线缆400利用线缆连接器410而连接至基本线缆300,以将显示模块100与驱动器200连接的情形。作为延长线缆400的线束线缆的一部分由虚设线缆构成。就是说,与添加到基本线缆300的引脚N+1连接的线缆部分由断路线缆构成。因此,通过添加到基本线缆300的引脚N+1传输的状态检查信号未传输至线缆检查单元210。因此,线缆检查单元210向时序控制器传输表示使用延长线缆400的信息。
就是说,当通过添加到基本线缆的引脚N+1接收到状态检查信号时,确定未使用延长线缆,当通过与添加到基本线缆的引脚N+1连接的虚设线缆未接收到状态检查信号时,确定使用延长线缆。
利用由线缆检查单元210检测的信息,时序控制器230从存储器220读取对应的光学补偿数据。之后,时序控制器230应用读取的光学补偿数据并给显示模块100提供电力。
尽管在上面的示例中包括一条虚设线缆,但根据延长线缆的各种不同的长度,可增加添加的引脚的数量。因此,可改变线缆连接器410和线缆检查单元210的构造。
根据本发明的OLED显示装置及其光学补偿方法具有以下效果。
第一,可根据用户的使用环境自动执行光学补偿。
第二,可解决在显示模块与驱动器分离的显示装置中由于使用额外线缆而导致的光学补偿问题。
第三,可解决在显示模块与驱动器分离的显示装置中由于使用额外线缆而发生的电压降所导致的问题。
尽管参照示例性实施方式描述了本发明,但本领域技术人员将理解,在不背离所附权利要求中描述的本发明的技术精神和范围的情况下,可在本发明中进行各种修改和变化。
