技术领域
本申请涉及显示技术领域,尤其涉及一种像素驱动电路、显示面板及电子设备。
背景技术
有源矩阵有机发光二极体面板(Active Matrix/Organic Light Emitting Diode,AMOLED)显示电路,每个像素电路包括多个薄膜晶体管(Thin Film Transistor,TFT)驱动开关和一个有机发光二极管(Organic Light-Emitting Diode,OLED),通常采用7T1C(7个TFT晶体管和1个电容组成)像素补偿电路,以及驱动点亮各个显示器件单元的驱动电路。其中:7T1C驱动电路输入信号包含:OLED发光控制信号(Emission,EM)、Scan[n]、Scan[n-1]、Vini(初始复位信号)、Vdata(数据信号)、Vdd(高位信号);驱动电路通常包括Scan GOA(Gate Driver On Array,阵列基板行驱动扫描电路)电路和EM阵列基板行驱动电路(Emit Gate Driver On Array,EM GOA),Scan GOA和EM GOA(简称EOA)电路中采用CK(时钟信号)\XCK(外部时钟信号)\VGL(低电位)\VGH(高电位)\STV(初始信号)等输入信号,通过时序电路MOS开关单元后(多个TFT和多个电容组成),输出级传后的每行驱动时序给显示区的像素电路,如图1所示。
在AMOLED显示模组中,通常采用RGBG像素排列方式(每两个像素共享一个绿色的子像素,这使得蓝色OLED的面积可以更大,同时带来更高的面板开口率,这样一来就使得达到相当发光强度所需要的电流降低,从而延缓衰减速度使得显示面板寿命提高),此种排列方式和传统RGB条形排列方式相比,一列像素上有2种显示颜色,因Gate(栅线)GOA集成电路在 级传过程中,容易因级传过程中的R(电阻)和C(电容)引起的波形延时,发生扫描信号Gate输出波形延时,在像素电路单元的Vdata电压写入阶段的过程中,容易写入上一帧的Vdata电压,导致纯色显示色偏,例如红色画面偏蓝,蓝色画面偏红。

各数据线3均连接至多路分配器电路4,通过多路分配器电路4可以使得数据线3连通集成电路(Integrated Circuit,IC)芯片,进而可以使得数据线3控制与之连接的像素电路1的工作状态。
本申请实施例的像素驱动电路,通过在显示区域增设数据线,在非显示区域增设多路分配器电路,将单元列的同种颜色子像素采用同一数据线输入数据信号,保证了画面显示的一致性,改善了显示面板色偏的问题。
可选的,在本申请一实施例中,如图2所示,像素驱动电路还包括:
与所述IC芯片的输出端连接的阵列基板行驱动GOA单元5;所述GOA单元5包括第一时钟信号线51、第二时钟信号线52、第三时钟信号线53、第四时钟信号线54以及与奇数行栅线2连接的多个第一GOA电路55和与偶数行栅线2连接的多个第二GOA电路56;
所述第一GOA电路55连接所述第一时钟信号线51和所述第二时钟信号线52,所述第二GOA电路56连接所述第三时钟信号线53和所述第四时钟信号线54;
所述第一时钟信号线51和所述第二时钟信号线52的时序相反,所述第三时钟信号线53和所述第四时钟信号线54的时序相反。
GOA单元5与IC芯片的输出端连接,包括四条时钟信号线,在原有电路的基础上增设了两条时钟信号线,还包括多个第一GOA电路55以及多个第二GOA电路56,第一GOA电路55的数量与像素阵列中奇数行栅线2的数量相等,第二GOA电路56的数量与像素阵列中偶数行栅线2的数量相等,即每一条奇数行的栅线2对应于一个第一GOA电路55,每一条偶数行的栅线2对应于一个第二GOA电路56。
其中,第一时钟信号线51和第二时钟信号线52的时序相反,且第一时钟信号线51和第二时钟信号线52作为输入信号线与各第一GOA电路55连接,用于向各第一GOA电路55输入时钟信号。
第三时钟信号线53和第四时钟信号线54的时序相反,且第三时钟信号线53和第四时钟信号线54作为输入信号线与各第二GOA电路56连接,用于向各第二GOA电路56输入时钟信号。
其中,由于GOA单元5与IC芯片的输出端连接,其具体的连接形式为:第一时钟信号线51与IC芯片输出端的第一时钟端口连接,第二时钟信号线52与IC芯片输出端的第二时钟端口连接,第三时钟信号线53与IC芯片输出端的第三时钟端口连接,第四时钟信号线54与IC芯片输出端的第四时钟端口连接;奇数行栅线2对应的第一GOA电路55、偶数行栅线2对应的第二GOA电路56分别连接IC芯片输出端的不同驱动端口。通过增设两条时钟信号线,可以改善由于时延造成的不同颜色数据信号的误写入,从而改善面板色偏。
可选的,在本申请一实施例中,如图2所示,按照行数递增的排列顺序,各相邻的所述第一GOA电路55之间连接且形成奇数行栅线2的级传、各相邻的所述第二GOA电路56之间连接且形成偶数行栅线2的级传;
其中,除最后一级所述第一GOA电路55外,每一级所述第一GOA电路55的输出端与相邻下一级所述第一GOA电路55的输入端连接;除最后一级所述第二GOA电路56外,每一级所述第二GOA电路56的输出端与相邻下一级所述第二GOA电路56的输入端连接。
与奇数行栅线2连接的多个第一GOA电路55之间,按照行数依次递增的顺序,实现前一级第一GOA电路55与后一级第一GOA电路55之间的连接,进而形成奇数行栅线2的级传。相应的,与偶数行栅线2连接的多个第二GOA电路56之间,按照行数依次递增的顺序,实现前一级第二GOA电路56与后一级第二GOA电路56之间的连接,进而形成偶数行栅线2的级传。例如,与第一行栅线2连接的第一GOA电路55的输出端和与第三行栅线2连接的第一GOA电路55的输入端连接,与第三行栅线2连接的第一GOA电路55的输出端和与第五行栅线2连接的第一GOA电路55的输入端连接;与第二行栅线2连接的第二GOA电路56的输出端和与第四行栅线2连接的第二GOA电路56的输入端连接,与第四行栅线2连接的第二GOA电路56的输出端和与第六行栅线2连接的第二GOA电路56的输入端连接。
通过实现奇数行级传和偶数行级传的区分,可以使得奇数行极传对应于第一时钟信号线和第二时钟信号线,偶数行极传对应于第三时钟信号线和第四时钟信号线,进而可以改善由于时延造成的不同颜色数据信号的误写入, 从而改善面板色偏。
需要说明的是,图2中所示的像素阵列为最小驱动单元,通过多个最小驱动单元可组合为与显示面板对应的驱动电路。如针对显示面板对应1080列、2400行像素电路的情况,此时在列方向上需要有270个最小驱动单元,在行方向上需要有600个最小驱动单元。
其中,如图4所示,第一时钟信号线(CK1)对应的波形为第一栅线(第一行栅线)的波形和第三栅线(第三行栅线)的反向波形叠加后生成的波形,第二时钟信号线(XCK1)与第一时钟信号线的波形相反,第三时钟信号线(CK2)对应的波形为第二栅线(第二行栅线)的波形和第四栅线(第四行栅线)的反向波形叠加后生成的波形,第四时钟信号线(XCK2)与第三时钟信号线的波形相反,且第三时钟信号线(CK2)相对第一时钟信号线(CK1)延后半个脉冲。
可选的,在本申请一实施例中,如图2和图4所示,对于相邻的奇数行栅线2和偶数行栅线2,其中,相对于奇数行栅线2对应的第一GOA电路55的时钟信号,偶数行栅线2对应的第二GOA电路56的时钟信号延后半个脉冲。
通过增加两条时钟信号线,实现奇数行级传和偶数行级传的区分,并针对相邻的奇数行栅线2和偶数行栅线2,设置偶数行栅线2对应的第二GOA电路56的时钟信号延后奇数行栅线2对应的第一GOA电路55的时钟信号半个脉冲,可以与数据线3进行配合,实现在一个连续的时间内,控制每一列像素电路1中对应于同一颜色子像素的像素电路1根据脉冲信号依序工作。
可选的,在本申请一实施例中,如图2所示,所述数据线3包括第一类型数据线31、第二类型数据线32和第三类型数据线33;
每列像素电路1为一电路组,对应相同颜色子像素的所述电路组为第一电路组,对应两个颜色子像素的所述电路组为第二电路组;
所述第一类型数据线31与所述第二电路组中对应第一颜色子像素的所述像素电路1连接,所述第二类型数据线32与所述第二电路组中对应第二颜色子像素的所述像素电路1连接;所述第三类型数据线33与所述第一电路组中的所述像素电路1连接。
沿第二方向排列的数据线3对应于三种类型,每一类型的数据线3可分别连接至对应的像素电路1,并控制像素电路1的工作状态。其中针对每一列像素电路1可形成一电路组,根据电路组所对应的不同子像素可将电路组确定为2种不同类型的电路组。若电路组中的像素电路1对应相同颜色子像素,则该电路组为第一电路组,若电路组中的像素电路1对应两个颜色子像素,则该电路组为第二电路组。
针对数据线3而言,确定与第一电路组中的像素电路1连接的数据线3为第三类型数据线33,确定与第二电路组中对应第一颜色子像素的像素电路1连接的数据线3为第一类型数据线31,确定与第二电路组中对应第二颜色子像素的像素电路1连接的数据线3为第二类型数据线32。
由于像素阵列采用RGBG像素排列方式,因此第一电路组中的像素电路1对应绿色子像素,第一颜色子像素可以为红色或者蓝色子像素,相应的第二颜色子像素可以为蓝色或者红色子像素。
通过划分数据线类型,可以实现将对应不同颜色子像素的像素电路与相应的数据线连接,进而可以将单元列的同种颜色子像素采用同一数据线输入数据信号,保证了画面显示的一致性,改善了显示面板色偏的问题。
可选的,在本申请一实施例中,如图2所示,所述第一类型数据线31、所述第二类型数据线32和所述第三类型数据线33的数量之和为所述像素电路1所对应的列数的两倍倍;所述第一类型数据线31、所述第二类型数据线32、两条所述第三类型数据线33、所述第二类型数据线32、所述第一类型数据线31和两条所述第三类型数据线33在所述第二方向上依次排列;其中,每条所述第三类型数据线33与所述第一电路组中半数的所述像素电路1连接,且与一条所述第三类型数据线33连接的至少两个所述像素电路1相邻或者间隔排布。

以图2为例进行阐述,在第二方向上数据线D1、D1-1、D2、D2-1、D3、D3-1、D4、D4-1依次排列。第一列像素电路1中与R(红色)子像素对应的像素电路1通过D1(第一类型数据线)驱动,第一列像素电路1中与B(蓝色)子像素对应的像素电路1通过D1-1(第二类型数据线)驱动;同理第三列像素电路1中与B子像素对应的像素电路1通过D3(第二类型数据线)驱动,第三列像素电路1中与R子像素对应的像素电路1通过D3-1(第一类型数据线)驱动;第二列像素电路1中与G(绿色)子像素对应的像素电路1也采用奇数行偶数行分别用D2(第三类型数据线)和D2-1(第三类型数据线)驱动,第四列像素电路1的驱动方式同第二列。在第二方向上,第一类型数据线31、第二类型数据线32、两条第三类型数据线33、第二类型数据线32、第一类型数据线31和两条第三类型数据线33依次排列。
其中,针对第三类型数据线33而言,每条第三类型数据线33与第一电路组中一半的像素电路1连接,且可以连接相邻或者间隔设置的像素电路1。由于第一电路组中对应的像素电路1至少为4个,因此一条第三类型数据线33连接的至少两个像素电路1可以相邻或者间隔排布。图2中示出的是一条第三类型数据线33与间隔的两个像素电路1连接的示例。

需要说明的是,针对两个第一电路组而言,第三类型数据线33与第一开关43和第二开关44连接的情况可以相同或者不同,图2中示意出的是不同的情况。在相同时,两个第一电路组中的左侧的第三类型数据线33均连接第一开关43或第二开关44,在不同时,可以是图2所示的第二列像素电路1左侧的第三类型数据线33连接第二开关44,第四列像素电路1左侧的第三类型数据线33连接第一开关43,还可以是其他情况,这里不再一一列举。
可选的,在本申请一实施例中,如图2和图4所示,在所述第一驱动线41控制所述第一开关43导通时,在各栅线2对应的工作脉冲内,与所述第一类型数据线31连接的所述像素电路1处于工作状态、与对应于所述第一开关43的所述第三类型数据线33连接的所述像素电路1处于工作状态;
