Description

显示装置的驱动方法 技术领域
本发明涉及显示技术领域,尤其涉及一种显示装置的驱动方法。
背景技术
随着显示技术的发展,有机发光二极管 (Organic Light Emitting Display,OLED) 显示装置、迷你发光二极管(Mini Light Emitting Display,Mini-LED)显示装置及微发光二极管(Micro Light Emitting Display,Micro-LED)显示装置等自发光显示装置已经越来越多,被业界公认为是最有发展潜力的显示装置。
上述自发光显示装置具有呈阵列式排布的多个像素,通过像素驱动电路驱动发光单元发光。常见的像素驱动电路如图1所示,包括一开关薄膜晶体管T10、一驱动薄膜晶体管T20、一存储电容C10、以及一发光单元D,驱动方法有模拟驱动方法及数字驱动方法,采用模拟驱动方法时,由于驱动薄膜晶体管T20长时间工作在饱和区会造成其阈值电压(Vth)发生漂移,导致面板显示画面产生亮度不均匀,影响显示效果,发光单元D根据需要可以为OLED,Mini-LED或Mico-LED
而在自发光显示装置的数字驱动方法中,驱动薄膜晶体管T20的栅极仅输出两个伽马(Gamma)电压准位,分别为:使得有机发光二级管最亮的最高伽马Gamma准位(GM1)和使得发光单元最暗的最低Gamma准位(GM9),按照晶体管电流电压I-V方程:
I ds,sat=k*(V gs-Vth) 2=k*(V A-V B-Vth) 2       
其中,I ds,sat为晶体管导通电流,k为本征导电因子,Vgs为驱动薄膜晶体管T20的栅源极电压,Vth为驱动薄膜晶体管T20的阈值电压,V A为驱动薄膜晶体管T20的栅极电压,V B为驱动薄膜晶体管T20的源极电压。
如图2所示,在子场非等切的数字驱动方式中,正常的一个帧被切成多个子场(Subframe,SF),子场的时间权重按照
Figure 987294dest_path_image001
进行驱动,通过控制子场的亮暗产生脉冲宽度调制(Pulse width modulation, PWM)亮度信号,结合人眼对亮度感知的时间上积分原理,可使用数位电压(GM1和GM9)来显示不同灰阶亮度影像,但该方法在显示时容易出现闪烁问题,并在低灰阶时尤为明显,为了解决上述的闪烁问题时,现有技术会使用灰阶打散的方式,将原有的低权重子场拆分几个更小的子场,并插入到其他子场中间,以避免闪烁,但增加子场数量,就需要增加硬件的驱动频率,实际应用时,存在硬件实现难度大,成本高的问题。

本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果,以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图7,本发明提供一种显示装置的驱动方法,包括如下步骤:
步骤S1、提供一显示装置,所述显示装置包括阵列排布的多个子像素10。
步骤S2、将一帧画面中各个子像素10的数据信号划分为多个具有不同时间权重的子场;
步骤S3、将所述多个子像素10划分为至少两个驱动组,不同驱动组中的子像素10对应的子场显示顺序不同;
步骤S4、按照各个子像素10对应的子场显示顺序驱动各个子像素进行画面显示。
具体地,结合图3及图4,在本发明的第一实施例中,所述步骤S2中将所述多个子像素10划分为两组,其中奇数行的子像素10为第一组,偶数行的子像素10为第二组。
进一步地,如图4所述,在本发明的第一实施例中,所述步骤S2中将一帧画面中各个子像素10的数据信号划分为4个具有不同时间权重的子场,分别为第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4,所述第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的时间权重依次增加。
优选地,所述第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的时间权重的比值分别为1:2:4:8,当然这并非对本发明的限制,具体比值可根据实际需要进行选择。
如图4所示,驱动时,所述步骤S4中,奇数行的子像素10按照第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的顺序依次显示;偶数行的子像素10按照第四子场SF4、第二子场SF2、第一子场SF1及第三子场SF3及的顺序依次显示。
具体地,所述步骤S1中,对应每一行子像素10设有一条扫描线20,每一行子像素10均电性连接其对应的扫描线20。所述多个子像素10包括第一子像素11、第二子像素12及第三子像素13,所述第一子像素11、第二子像素12及第三子像素13的颜色不同,在同一行子像素中,所述第一子像素11、第二子像素12及第三子像素13依次重复排列,同一列的子像素10的颜色相同。
优选地,所述上第一子像素11、第二子像素12及第三子像素13分别为红色、绿色及蓝色子像素。
举例来说,在本发明的第一实施例中,在第一帧画面Frame1中,第一行的子像素10按照第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的顺序依次显示,第二行的子像素10按照第四子场SF4、第二子场SF2、第一子场SF1及第三子场SF3的顺序依次显示,以第一子像素11发光为例,在P1阶段,第一行第一列的第一子像素11发光;在P2阶段,第二行第一列的第一子像素11发光;在P3阶段,第一行第一列的第一子像素11发光,由于第一行第一列的第一子像素11与第二行第一列的第一子像素11位置靠近,人眼无法识别清楚,故可以认为是同一位置发光,能够有效解决数字驱动的闪烁问题,且不增加更多的子场,仅需要改变子场显示顺序即可实现,不会导致驱动频率增加,产品品质提升的同时无需增加成本。
具体地,请参阅图5及图6,在本发明的第二实施例中,所述步骤S2中将所述多个子像素10划分为四组,其中奇数行奇数列的子像素10为第一组,奇数行偶数列的子像素10为第二组,偶数行奇数列的子像素10为第三组,偶数行偶数列的子像素10为第四组。

优选地,所述第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的时间权重的比值分别为1:2:4:8,当然这并非对本发明的限制,具体比值可根据实际需要进行选择。
驱动时,所述步骤S4中,奇数行奇数列的子像素10按照第一子场SF1、第二子场SF2、第三子场SF3及第四子场SF4的顺序依次显示;
奇数行偶数列的子像素10按照第二子场SF2、第一子场SF1、第三子场SF3及第四子场SF4的顺序依次显示;

进一步地,如图3所示,所述步骤S1中,对应每一行子像素10设有两条扫描线20,在同一行子像素10中,奇数列10的子像素连接一条扫描线20,偶数列的子像素10连接另一条扫描线20。所述多个子像素包括第一子像素11’、第二子像素12’、第三子像素13’及第四子像素14’,所述第一子像素11’、第二子像素12’、第三子像素13’及第四子像素14’的颜色不同,其中奇数行奇数列的子像素10为第一子像素11’,奇数行偶数列的子像素10为第二子像素12’,偶数行奇数列的子像素10为第三子像素13’,偶数行偶数列的子像素10为第四子像素14’。
优选地,所述第一子像素11’、第二子像素12’、第三子像素13’及第四子像素14’分别显示红色、绿色、蓝色及白色。
如图6所示,在P4至P7阶段,奇数行奇数列的子像素10、奇数行偶数列的子像素10、偶数行奇数列的子像素10及偶数行偶数列的子像素10分别发光,四个空间错开且相邻的子像素10在P4至P7阶段分别发光,从而实现,通过空间打散取代现有的灰阶打散,有效解决数字驱动的闪烁问题,且不增加更多的子场,仅需要改变子场显示顺序即可实现,不会导致驱动频率增加,产品品质提升的同时无需增加成本。
值得一提的是,本发明的显示装置根据需要可以为OLED显示装置、Mini-LED显示装置或Micro-LED显示装置等自发光显示装置。
进一步地,虽然本发明的第一及第二实施例中仅示意了4个子场的情况,但实际上本发明对于子场的具体数量并无严格限制,其他数量例如6个、或8个子场的驱动方式也适用于本发明,并且对于4个子场的驱动方式,各个子场的显示顺序也可以为上述第一或第二实施例以外的显示顺序,这些均可以根据实际应用时的需求进行优化选择,并不会影响本发明的实现。
从而,本发明通过空间打散取代现有的灰阶打散,能够实现在不增加驱动频率的情况下,解决数字驱动的闪烁问题,提升产品品质及竞争力。
综上所述,本发明提供一种显示装置的驱动方法,包括如下步骤:步骤S1、提供一显示装置,所述显示装置包括阵列排布的多个子像素;步骤S2、将一帧画面中各个子像素的数据信号划分为多个具有不同时间权重的子场;步骤S3、将所述多个子像素划分为至少两个驱动组,不同驱动组中的子像素对应的子场显示顺序不同;步骤S4、按照各个子像素对应的子场显示顺序驱动各个子像素进行画面显示,通过设置不同驱动组的子像素的子场显示顺序不同,能够减少因数字驱动而导致的画面闪烁,且无需增加驱动频率。
以上所述,对于本领域的普通技术人员来说,可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形,而所有这些改变和变形都应属于本发明权利要求的保护范围。
