当然,多个第一发光器件还可包括发白光的第一发光器件。多个第二发光器件A也可以包括发白光的第二发光器件A。
在一些示例中,第一发光器件为有机发光二极管(Organic Light-Emitting Diode,OLED)。
在一些示例中,第二发光器件A为OLED。
如图3A和图3B所示,显示面板100还包括多根数据线14,一列子像素中的像素驱动电路与一根数据线14电连接。多根数据线14包括第一数据线141和第二数据线142。示例的,第一数据线141为多条第一数据线141,第 二数据线142为多条第二数据线142。
示例的,多根数据线14同层设置。又示例的,多根数据线14至少部分同层设置。同层设置的多根数据线14通过构图工艺同步形成。
本公开中,图3A和图3B仅示出了部分数据线,实质上,每列子像素均电连接一根数据线。
第一数据线141与包含虚拟子像素D的一列子像素中的像素驱动电路电连接。示例的,如图3A所示,第1列子像素中包含虚拟子像素D,第一数据线141-1与位于第1列的子像素中的像素驱动电路电连接。又示例的,如图3A所示,第2列的子像素中包含虚拟子像素D和有效子像素P,第一数据线141-2与位于第2列的子像素中的像素驱动电路电连接。
第二数据线142和与一列第二发光器件A位于同一列的一列子像素中的像素驱动电路电连接;该列第二发光器件A中的一个第二发光器件A和与第一数据线连接的一个虚拟子像素D中的像素驱动电路电连接。示例的,如图3A所示,透光区11中的第1列第二发光器件A与第13列的子像素位于同一列,第二数据线142-1和位于第13列的子像素中的像素驱动电路电连接。又示例的,如图3A所示,透光区11中的第2列第二发光器件A与第15列的子像素位于同一列,第二数据线142-2和位于第15列的子像素中的像素驱动电路电连接。
每个第二数据线142具有一段第一绕线部,该第一绕线部绕过透光区11布线,可使第二数据线142不穿过透光区11,以避免第二数据线142对透光区11的透光率的影响。
在一些示例中,如图3A所示,多根数据线14还包括第三数据线143。示例的,第三数据线143为多根第三数据线143。第三数据线143仅和与任意列的第二发光器件A位于不同列,且一列均为有效子像素P的子像素中的像素驱动电路电连接。即,第三数据线143仅与位于第二区13中的与任意列的第二发光器件A位于不同列的一列有效子像素P的像素驱动电路电连接。
示例的,如图3A所示,第24列的有效子像素P与任意列的第二发光器件A位于不同列,且第24列的多个有效子像素P均位于第二区13,第三数据线143-1与位于第24列的有效子像素P的像素驱动电路电连接。
又示例的,如图3A所示,第22列的有效子像素P与任意列的第二发光器件A位于不同列,且第22列的多个有效子像素P均位于第二区13,第三数据线143-2与位于第22列中的有效子像素P的像素驱动电路电连接。第三数据线143-2具有一段第二绕线部,该第二绕线部绕过透光区11设置,可使 第三数据线143-2不穿过透光区11,以避免第三数据线143-1对透光区11的透光率的影响。也就是说,若与第三数据线143电连接的有效子像素P在沿数据线14的方向上位于透光区的一侧,则第三数据线需设置一段第二绕线部。
在一些示例中,位于透光区11中第1列第1行的第二发光器件A与位于第1列第3行的虚拟子像素D中的像素驱动电路电连接。例如,如图3A和图3B所示,一个第二发光器件A与一个虚拟子像素D中的像素驱动电路通过一根辅助连接线15连接。
这里,图3A和图3B仅为示意,虽然图3A和图3B中仅部分第二发光器件A与虚拟子像素D中的像素驱动电路通过辅助连接线15连接,但并不代表透光区11中仅部分第二发光器件A与虚拟子像素D中的像素驱动电路电连接。实质上,透光区11中的每个第二发光器件A均与对应的虚拟子像素D中的像素驱动电路电连接。
示例的,该辅助连接线15的材料为氧化铟锡(Indium tin oxide,ITO)。ITO在薄膜状时呈透明,因此,采用ITO制作的辅助连接线呈透明态,因此,使得辅助连接线对透光区11的透光率几乎不产生影响。示例的,多根辅助连接线15同层设置。又示例的,多根辅助连接线15与多根数据线14至少部分同层设置。同层设置的多根辅助连接线15通过构图工艺同步形成。

如图10A所示,第三晶体管T3的栅极与扫描信号线GL电连接,第三晶体管T3的第一极与数据线DL(即,上述显示面板100中的数据线14)电连接,第三晶体管T3的第二极与驱动晶体管Td的栅极电连接。驱动晶体管Td的第一极与第一电源线VDD电连接,驱动晶体管Td的第二极与发光器件L(即,上述显示面板的第一发光器件或第二发光器件A)的阳极电连接。发光器件L的阴极与第二电源线VSS电连接。第一存储电容器Cst的一端与驱动晶体管Td的栅极电连接,第一存储电容器Cst的另一端与驱动晶体管Td的第二极电连接。示例的,第一电源线VDD被配置为提供高电压信号,第二电源线VSS被配置为提供低电压信号。
在另一些示例中,如图10B所示,像素驱动电路30包括驱动晶体管Td、第四晶体管T4、第五晶体管T5、第六晶体管T6、第七晶体管T7、第八晶体 管T8、第九晶体管T9、和第一存储电容器Cst。即,该像素驱动电路的电路结构为7T1C电路结构。
如图10B所示,第八晶体管T8的栅极与扫描信号线GL电连接,第八晶体管T8的第一极与数据信号线DL(即,上述显示面板中的数据线14)电连接,第八晶体管T8的第二极与驱动晶体管Td的第一极电连接。第九晶体管T9的栅极与扫描信号线GL电连接,第九晶体管T9的第一极和第二极分别与驱动晶体管Td的第二极和栅极电连接。第四晶体管T4的栅极与使能信号线EM电连接,第四晶体管T4的第一极与第一电源线VDD电连接,第四晶体管T4的第二极与驱动晶体管Td的第一极电连接。第五晶体管T5的栅极与使能信号线EM电连接,第五晶体管T5的第一极与驱动晶体管Td的第二极电连接,第五晶体管T5的第二极与发光器件L的阳极电连接。第六晶体管T6的栅极与复位信号线RST(N)电连接,第六晶体管T6的第一极与初始化信号线VIN电连接,第六晶体管T6的第二极与驱动晶体管Td的栅极电连接。第七晶体管T7的栅极与下一行像素驱动电路30中的第六晶体管T6连接的复位信号线RST(N+1)电连接,第七晶体管T7的第一极与初始化信号线VIN电连接,第七晶体管T7的第二极与发光器件L(即,上述显示面板的第一发光器件或第二发光器件A)的阳极电连接。第一存储电容器Cst的一端与驱动晶体管Td的栅极电连接,第一存储电容器Cst的另一端与第一电源线VDD电连接。发光器件L的阴极与第二电源线VSS电连接。示例的,第一电源线VDD被配置为提供高电压信号,第二电源线VSS被配置为提供低电压信号。
上述仅仅是对像素驱动电路30的举例说明,关于像素驱动电路30的电路结构不限于上述两种结构,其还可以是其它类型的电路结构,这里不再一一列举。但应理解,不管像素驱动电路30是哪种电路结构,其至少包括一个驱动晶体管、一个起开关作用的晶体管以及一个第一存储电容器。
在本公开中,第一极为晶体管的源极和漏极中的一者,第二极为晶体管的源极和漏极中的另一者。由于晶体管的源极、漏极在结构上可以是对称的,所以其源极、漏极在结构上可以是没有区别的。也就是说,本公开的实施例中的晶体管的第一极和第二极在结构上可以是没有区别的。示例的,对于P型晶体管,将第二极称为漏极,将第一极称为源极。又示例的,对于N型晶体管,将第一极称为漏极,将第二极称为源极。
此外,根据晶体管导电方式的不同,可以将晶体管分为增强型晶体管和耗尽型晶体管。本公开实施例中的各个晶体管可以为增强型晶体管,也可以为耗尽型晶体管,对此不作限制。
示例的,每个子像素中的像素驱动电路30相同。多个子像素中的像素驱动电路30通过构图工艺同步形成。
显示面板100还包括多个第一晶体管。参考图3A、3B、以及图4A,一条第一数据线141和一条第二数据线142之间通过一个第一晶体管T1连接,第一晶体管T1被配置为在开启时,使第一数据线141和第二数据线142连为一体;在关闭时,使第一数据线141和第二数据线142不连接。
示例的,多个第一晶体管T1通过构图工艺同步形成。
在一些示例中,第一晶体管T1的栅极通过第一控制线16连接到第一控制端,来自第一控制端的第一控制信号通过第一控制线16传输至第一晶体管T1,以控制第一晶体管T1的开启或关闭。例如,第一晶体管T1为N型晶体管,响应于来自第一控制端的第一控制信号为高电平信号,第一晶体管T1开启。又例如,第一晶体管T1为P型晶体管,响应于来自第一控制端的第一控制信号为低电平信号,第一晶体管T1关闭。
本公开中,在第一晶体管T1开启的情况下,第一数据线141和第二数据线142连为一体,来自第二数据线142的信号输入端的第二数据信号通过连为一体的第二数据线142和第一数据线141传输至与第二发光器件A电连接的像素驱动电路中,以控制该第二发光器件A发光,以使显示面板的透光区11显示图像。
需要说明的是,在第一晶体管T1开启的情况下,第一信号线141可不向与第二发光器件A电连接的虚拟子像素D中的像素驱动电路中传输第一数据信号,以防止第一数据信号和第二数据信号相互干扰。例如,可通过处理器控制在第一晶体管T1开启时,第一数据线141的信号输入端不输出第一数据信号,或不输出可使第二发光器件A发光的数据信号,即,处理器可控制第一信号线141的信号输入端输出虚拟的第一数据信号;或者,通过控制开关(例如下文中的第二晶体管T2)断开第一数据线141,阻止来自第一数据线141的信号输入端的第一数据信号传输至与第二发光器件A电连接的像素驱动电路中。
在第一晶体管T1关闭的情况下,第一数据线141和第二数据线142不连接,来自第一数据线141的信号输入端的第一数据信号传输至与第一数据线141电连接的像素数据电路中,以使与第一数据线141电连接的一列有效子像素P均可正常显示。
这样,与第一数据线141与第二数据线142直接通过连接线电连接,只能将透光区位于显示区1的最顶端相比,本公开的实施例可使透光区11位于 显示区1的任意位置,且不影响第二区13的正常显示。
本公开中,显示面板100中的各行子像素之间的间距相等,各列子像素之间的间距也相等,以使显示面板100具有良好的显示效果。图3A和3B中第2行子像素和第三行子像素之间的间距、第6行与第7行之间的间距、以及第23列和第24列之间的间距仅为一种示意,为了更清楚的示意第一数据线141和第二数据线142之间的连接,以及各数据线的布线方式,其并不代表显示面板中子像素之间的实际间距。
在一些实施例中,第一晶体管T1为薄膜晶体管(Thin Film Transistor,简称TFT)。
在一些示例中,参考图11,显示面板100包括衬底101,每个子像素中的像素驱动电路设置于衬底101上。示例的,衬底101为玻璃衬底。
每个像素驱动电路中的驱动晶体管Td包括有源层、源极、漏极、栅极及栅绝缘层,源极和漏极分别与有源层接触。
示例的,有源层2113的材料包含非晶铟镓锌氧(a-IGZO)、氮氧化锌(ZnON)、铟锌锡氧化物(IZTO)、非晶硅(a-Si)、多晶硅(p-Si)、六噻吩、聚噻吩等中的一种。
参考图11,每个有效子像素P中的第一发光器件210包括阳极212、发光功能层213以及阴极214。每个第二发光器件A也包括阳极212、发光功能层213以及阴极214。
示例的,发光功能层213仅包括发光层。又示例的,发光功能层213除包括发光层外,还包括电子传输层(election transporting layer,简称ETL)、电子注入层(election injection layer,简称EIL)、空穴传输层(hole transporting layer,简称HTL)以及空穴注入层(hole injection layer,简称HIL)中的一层或多层。
在一些示例中,第一发光器件210和第二发光器件A的靠近衬底101的阳极212呈不透明,远离衬底101的阴极214呈透明或半透明。
在另一些示例中,第一发光器件210和第二发光器件A的靠近衬底101的阳极212呈透明或半透明,远离衬底101的阴极214呈不透明。
在一些示例中,如图11所示,显示面板100还包括像素界定层215,像素界定层215包括多个开口区,一个第一发光器件210设置于一个开口区中,一个第二发光器件A设置于一个开口区中。
在又一些示例中,如图11所示,显示面板100还包括设置在像素驱动电路和与该像素驱动电路对应的第一发光器件的阳极212之间的平坦层216。第 一发光器件210的阳极通过设置于平坦层216上的过孔与像素驱动电路中驱动晶体管Td的第二极电连接。第二发光器件A的阳极通过设置于平坦层216上的过孔与辅助连接线15连接(图11中未示出)。
示例的,平坦层50的材料包含但不限于聚硅氧烷系、亚克力系或聚酰亚胺系材料。
在又一些示例中,如图11所示,显示面板100还包括封装层217。
在一些实施例中,如图3B所示,与第一数据线141电连接的一列子像素中,位于第一区12的子像素均为虚拟子像素D。
在一个帧周期的扫描阶段中,对各行子像素中的像素驱动电路逐行进行扫描。即,从位于显示区1的第一行子像素中的像素驱动电路开始逐行扫描,依次向各行子像素中的每个像素驱动电路输入对应的数据信号,直至将数据信号输入位于显示区1的最后一行子像素中的各像素驱动电路。
基于此,在对透光区11中各第二发光器件A所在的像素行进行扫描的过程中,可使第一晶体管T1持续开启,直至与透光区11中的最后一行第二发光器件A电连接的像素驱动电路全部扫描结束。
示例的,参考图3B,当处理器向第3行(即,与透光区11中第1行的第二发光器件A位于同一行的像素行)的像素驱动电路输入栅极扫描信号时,还向第一晶体管输入第一控制信号,使第一晶体管T1开启。第一数据线141和第二数据线142通过开启的第一晶体管T1连为一体,第二数据信号被传输至与第一数据线141电连接的位于第3行的虚拟子像素D的像素驱动电路中,以使与该虚拟子像素D电连接的位于透光区11中第1行的第二发光器件A发光;当处理器向第4行的像素驱动电路接收到的扫描信号,第二数据信号被传输至与第一数据线141电连接的位于第4行的虚拟子像素D的像素驱动电路中,以使与该虚拟子像素D电连接的位于透光区11中第2行的第二发光器件A发光。直至第二数据信号被传输至与第一数据线141电连接的位于第6行的虚拟子像素D的像素驱动电路中,以使与该虚拟子像素D电连接的位于透光区11中第4行(即,与透光区11中最后一行的第二发光器件A位于同一行的像素行)的第二发光器件A发光,即透光区11中各第二发光器件A所在的像素行全部扫描结束。处理器向第一晶体管T1的栅极输入第一控制信号,使第一晶体管T1关闭。
在另一些实施例中,如图3A所示,与第一数据线141电连接的一列子像素中,位于第一区12的子像素包括虚拟子像素D和有效子像素P。
基于此,在对透光区11中的一个第二发光器件A所在的像素行进行扫描的过程中,若与第一数据线141电连接的子像素为有效子像素P,则关闭与该第一数据线141电连接的第一晶体管T1。若与第一数据线141电连接的子像素为虚拟子像素P,且该虚拟子像素D与透光区11中的第二行的一个第二发光器件A电连接,则开启与该第一数据线141电连接的第一晶体管T1。
示例的,参考图3A,当处理器向第3行(即,与透光区11中第1行的第二发光器件A位于同一行的像素行)的像素驱动电路输入栅极扫描信号时,还向与第一数据线141-2电连接的第一晶体管T1输入第一控制信号,以使第一晶体管T1关闭。由于第4行子像素中与第一数据线141-2电连接的子像素为虚拟子像素D,且该虚拟子像素D与透光区11中的第二行的一个第二发光器件A电连接,因此,当处理器向第4行(即,与透光区11中第2行的第二发光器件A位于同一行的像素行)的像素驱动电路输入栅极扫描信号时,处理器还向与第一数据线141-2电连接的第一晶体管T1输入第一控制信号,以使第一晶体管T1开启。
在一些实施例中,如图3A和3B所示,多个有效子像素P中位于第一区12中的有效子像素P均匀排布。这样,可使第一区12具有良好的显示效果。
在一些实施例中,显示面板100还包括第一连接线。第一连接线设置于第一区12远离数据线14的信号输入端的一侧。第一连接线的一端与第一晶体管T1的第一极电连接,第一连接线的另一端与第一数据线141电连接,第一晶体管T1的第二极与第二数据线142电连接。

在又一些实施例中,如图3A和3B、以及图4A-图4C所示,显示面板100还包括第一连接线17和第二连接线18。第一连接线17和第二连接线18均设置于第一区12远离数据线14的信号输入端的一侧。示例的,第一连接线17和第二连接线18均设置于与透光区11中的第一行第二发光器件A电连接的虚拟子像素D所在的像素行。例如第一连接线17和第二连接线18均设置于图3B中的第3行子像素所对应的区域。示例的,第一连接线17和第二连接线18同层设置。另示例的,第一连接线17和第二连接线18与多根数据线14至少部分同层设置。又示例的,与一个第一晶体管T1电连接的第一连接线17和第二连接线18与该第一晶体管T1同层设置。
第一连接线17的一端与第一晶体管T1的第一极电连接,第一连接线17的另一端与第一数据线141电连接。第二连接线18的一端与第一晶体管T1的第二极电连接,第二连接线18的另一端与第二数据线142电连接。
在一些实施例中,如图4B和图4C所示,显示面板100还包括至少一个第二晶体管T2;至少一个第二晶体管T2被配置为在开启时,使第一数据线141连为一体;在关闭时,使第一数据线141中位于第一区12的部分与位于第二区13中的部分断开,且与第二数据线142电连接。
示例的,第二晶体管T2为薄膜晶体管TFT。
示例的,多个第二晶体管T2至少部分同层设置。又示例的,多个第二晶体管T2至少部分与第一数据线141同层设置。同层设置的第二晶体管T2通过构图工艺同步形成。
在一些示例中,如图4B所示,透光区11位于显示区1的中部;第一数据线141包括第一部分1411、和位于第一部分1411两侧的第二部分1412和第三部分1413。第一部分1411位于第一区12,第二部分1412和第三部分1413位于第二区13;第二部分1412相对第三部分1413更靠近第一数据线141的信号输入端。
显示面板100包括一个第二晶体管T2;第一数据线141的第一部分1411和第二部分1412通过第二晶体管T2电连接。即,第二晶体管T2的第一极与第一数据线141的第一部分1411电连接,第二晶体管T2的第二极与第一数据线141的第二部分1412电连接。第二晶体管T2的栅极通过第二控制信号线21连接到第二控制端,以控制第二晶体管T2的开启或关闭。
示例的,第二晶体管T2设置于靠近第一数据线141的信号输入端的一侧,例如,位于显示区1的最后一行像素行的区域。
参考图3B、图4B、图5A以及图5B,以第一晶体管T1、第二晶体管T2以及像素驱动电路中的各个晶体管均为P型晶体管为例。
如图3B、图4B以及图5A所示,当处理器向与透光区11中任一个第二发光器件A电连接的像素驱动电路输入栅极扫描信号G1时,还向第一晶体管T1输入第一控制信号K1,第一控制信号K1为低电平信号,第一晶体管T1开启,第一数据线141和第二数据线142连为一体,来自第二数据信号线142的数据信号输入端的第二数据信号通过第一数据线141传输至与该第二发光器件A电连接的像素驱动电路中,以使该像素驱动电路根据第二数据信号驱动该第二发光器件A发光。此时,第二控制信号K2为高电平信号,第二晶体管T2关闭,使第一数据线141的第一部分1411和第二部分1412断开, 以阻止来自第一数据线141的信号输入端的第一数据信号传输至与该第二发光器件A电连接的像素驱动电路中。
如图3B、图4C以及图5B所示,当处理器向位于第二区13的任意一行像素驱动电路输入栅极扫描信号G2时,向第一晶体管T1输入第一控制信号K1,第一控制信号K1为高电平信号,第一晶体管T1关闭,第一数据线141和第二数据线142不连接。此时,第二控制信号K2为低电平信号,第二晶体管T2开启,第一数据线141的第一部分1411和第二部分1412连为一体,使得来自第一数据线141的信号输入端的第一数据信号通过第一数据线141传输至该行的像素驱动电路中,以使该行的与该像素驱动电路电连接的有效子像素P中的第一发光器件发光;来自第二数据线142的信号输入端的第二数据信号通过第二数据线142传输至该行的像素驱动电路中,以使该行的与该像素驱动电路电连接的有效子像素P中的第一发光器件发光。
在另一些示例中,如图4C所示,透光区11位于显示区1的中部。显示面板包括两个第二晶体管T2,第一部分1411和第二部分1412通过其中一个第二晶体管T21电连接,第一部分1411和第三部分1413通过另一个第二晶体管T22电连接。
示例的,第二晶体管T22设置于靠近第一数据线141的信号输入端的一侧,例如,位于显示区1的最后一行像素行的区域。第二晶体管T21设置于第二区13最靠近第一区12的一行子像素的位置。
这样,在第一晶体管T1开启的情况下,关闭连接第一部分1411和第二部分1412的第二晶体管T2,以阻止来自第一数据线141的信号输入端的第一数据信号传输至与第二发光器件A电连接的像素驱动电路中。关闭连接第一部分1411和第三部分1413的第二晶体管T2,可阻止来自第二数据线142的第二数据信号在传输至第一数据线141的第一部分1411的同时,还传输至第一数据线141的第三部分1413。
以第一晶体管T1、第二晶体管T2以及像素驱动电路中的各个晶体管均为P型晶体管为例。
如图3B、图4B以及图6A所示,当处理器向与透光区11中任一个第二发光器件A电连接的像素驱动电路输入栅极扫描信号G1时,还向第一晶体管T1输入第一控制信号K1,第一控制信号K1为低电平信号,第一晶体管T1开启,第一数据线141和第二数据线142连为一体,来自第二数据信号线142的数据信号输入端的第二数据信号通过第一数据线141传输至与该第二发光器件A电连接的像素驱动电路中,以使该像素驱动电路根据第二数据信号 驱动该第二发光器件A发光。此时,第二控制信号K21和K22均为高电平信号,第二晶体管T21和第二晶体管T22均关闭,使第一数据线141的第一部分1411和第二部分1412断开,以阻止来自第一数据线141的信号输入端的第一数据信号传输至与该第二发光器件A电连接的像素驱动电路中。
如图3B、图4B以及图6B所示,当处理器向第二区12的任意一行子像素(即,图2B中的第1行、第2行、第7行或第8行)的像素驱动电路输入栅极扫描信号G1时,向第一晶体管T1输入第一控制信号K1,第一控制信号K1为高电平信号,第一晶体管T1关闭,第一数据线141和第二数据线142不连接。此时,第二控制信号K21和K22均为低电平信号,第二晶体管T21和第二晶体管T22开启,第一数据线141的第一部分1411、第二部分1412和第三部分1413连为一体,使得来自第一数据线141的信号输入端的第一数据信号通过第一数据线141传输至该行的像素驱动电路中,以使该行的与该像素驱动电路电连接的有效子像素P中的第一发光器件发光;来自第二数据线142的信号输入端的第二数据信号通过第二数据线142传输至该行的像素驱动电路中,以使该行的与该像素驱动电路电连接的有效子像素P中的第一发光器件发光。
在一些实施例中,如图4C所示,显示面板还包括电容器C。为了与上述驱动电路中的第一存储电容器Cst区分,以下将该电容器C称为第二存储电容器C2。
第二存储电容器C2的第一存储电极与第一晶体管T1的第一极电连接,第二存储电容器C2的第二存储电极与第一晶体管T1的第二极电连接。这样,来自第二数据线142的信号输入端的第二数据信号传输至第二存储电容器C2的第二存储电极,使得第二存储电容器C2的第二存储电极的电压为第二数据信号的电压(记为V2),第二存储电容器C2的第一存储电极的电压为来自第一数据线141的信号输入端的第一数据信号的电压(记为V1)。这样,第一晶体管T1开启,根据电容器的电荷保持定律,第二存储电容器C2的第一存储电极的电压由V1跳变为V2,使得第一晶体管T1的第一极和第二极的电压在短时间内达到相同,减小压降,可减小第一晶体管T1对第二数据信号传输的影响(参考图7),提高显示面板亮度的均匀性。图7所示为第二数据信号由第二数据线传输至第一数据线的信号仿真波形图,其中,Q1为在第一晶体管T1的第一极和第二极之间电连接第二存储电容器C2后,第二数据信号由第二数据线传输至第一数据线的信号仿真波形图;Q2为在第一晶体管T1的第一极和第二极之间未电连接第二存储电容器C2的第二数据信号由第二 数据线传输至第一数据线的信号仿真波形图。
在一些实施例中,每行第二发光器件A中任意相邻两个第二发光器件A的间距相等,包含虚拟子像素D和的一行子像素中,任意相邻两个有效子像素P之间的间距等于相邻两个第二发光器件A之间的间距。这样,使得透光区11和第一区12的显示分辨率相等,提高显示面板的显示效果。
在一些示例中,如图3A和图3B所示,包含虚拟子像素D和有效子像素的一行子像素P中,任意相邻两个有效子像素P之间设置有三个虚拟子像素D。这里,由于第二区13中仅包括有效子像素P,因此,第二区13的分辨率高于第一区12和透光区11的分辨率。
在一些实施例中,如图3A和图3B所示,显示区1包括一个第一区12,该第一区12位于透光区11的沿垂直数据线方向的一侧。
在一些实施例中,如图8所示,显示区1包括两个第一区12,该两个第一区12分别位于透光区11的沿垂直数据线方向的两侧。透光区11位于显示区1的中部。这样,位于透光区11两侧的第一区12中的多个虚拟子像素D分别与透光区11中的第二发光器件A电连接,可使多根辅助连接线15和多跟数据线在显示面板中的布线位置更均匀。
在一些实施例中,如图9所示,显示区1包括两个第一区12,一个第一区12位于透光区11的沿垂直数据线方向的一侧,另一个第一区12位于透光区11的沿数据线方向的一侧。透光区11位于显示区1的中部。图7所示的多个子像素排布成12行18列,沿X方向依次为第1列至第18列,沿Y方向依次为第1行至第12行。
在一些示例中,显示面板100还包括多根栅线19和多根扫描信号连接线20。一行像素中的至少有效子像素P与一根栅线电连接。示例的,如图9所示,一根栅线19与第9行的像素中的子像素电连接,该行子像素中包括有效子像素P和虚拟子像素D。又示例的,如图7所示,一根栅线19与第2行的像素中的子像素电连接,该行子像素中仅包括有效子像素P。
每根扫描信号连接线20的一端和与一个第二发光器件A位于同一行的有效子像素P电连接的栅线19电连接,扫描信号连接线20的另一端和与该第二发光器件A电连接的虚拟子像素D的像素数据驱动电路电连接,且该虚拟子像素D的像素数据驱动电路和与该虚拟子像素D同行的有效子像素P电连接的栅线绝缘20。
示例的,如图9所示,第一数据线141-3与位于第4列的子像素中的像素驱动电路电连接,透光区11中的第1列第二发光器件A与第8列的子像素 位于同一列,第二数据线142-3和位于第8列的子像素中的像素驱动电路电连接;透光区11中第1列第1行的第二发光器件A与位于同行的虚拟子像素D的像素数据驱动电路通过辅助连接线15电连接;第一数据线141-3与第二数据线142-3之间通过第一晶体管T1电连接。
这样,在第一晶体管T1开启的情况下,第一数据线141-3和第二数据线142-3连为一体,来自第二数据线142-3的信号输入端的第二数据信号通过第一数据线141-3传输至与该第二发光器件A电连接的虚拟子像素D的像素数据驱动电路中,以使该第二发光器件A发光。
在第一晶体管T1关闭的情况下,第一数据线141-3和第二数据线142-3不连接,来自第一数据线141-3的信号输入端的第一数据信号传输至与第一数据线141-3电连接的像素数据电路中,以使与第一数据线141-3电连接的一列有效子像素P均可正常显示。
又示例的,如图9所示,透光区11中的第3列第二发光器件A与第12列的子像素位于同一列,第二数据线142-4和位于第12列的子像素中的像素驱动电路电连接;第一数据线141-4与位于第11列的子像素中的像素驱动电路电连接;透光区11中第3列第3行的第二发光器件A与位于同列的虚拟子像素D的像素数据驱动电路通过辅助连接线15电连接;第一数据线141-4与第二数据线142-4之间通过第一晶体管T1电连接;扫描信号连接线20的一端和与该第二发光器件A位于同一行(即,第9行)的有效子像素P电连接的栅线19-1电连接,扫描信号连接线20的另一端和与该第二发光器件A电连接的虚拟子像素D的像素数据驱动电路电连接,且该虚拟子像素D的像素数据驱动电路和与该虚拟子像素D同行(即,第5行)的有效子像素P电连接的栅线19-2绝缘。
这样,在第一晶体管T1开启的情况下,第一数据线141-2和第二数据线142-4连为一体,来自第二数据线142-4的信号输入端的第二数据信号通过第一数据线141-4传输至与该第二发光器件A电连接的虚拟子像素D的像素数据驱动电路中,来自栅线19-1的栅线扫描信号通过扫描信号连接线20传输至与该第二发光器件A电连接的虚拟子像素D的像素数据驱动电路中,以使该第二发光器件A正常发光。
在第一晶体管T1关闭的情况下,第一数据线141-4和第二数据线142-4不连接,来自第一数据线141-4的信号输入端的第一数据信号传输至与第一数据线142电连接的像素数据电路中,以使与第一数据线141-4电连接的一列有效子像素P均可正常显示;来自第二数据线142-4的信号输入端的第二数据信 号传输至与第二数据线142-4电连接的像素数据电路中,以使与第二数据线142-4电连接的一列有效子像素P均可正常显示。
此外,如图9所示,在透光区11沿数据线方向的一侧设置第一区12,增加了虚拟子像素D的数量,使得透光区中的第二发光器件A的数量随之增加,扩大了透光区11的面积。
本公开一些实施例提供一种显示面板的控制方法,包括S100-S300。
S100、处理器逐行向多行子像素输入栅极扫描信号。
S200、当处理器向与透光区11中任一的第二发光器件A电连接的像素驱动电路输入栅极扫描信号时,还向第一晶体管T1输入控制信号,以使第一晶体管开启T1。
S300、处理器通过多根数据线14向每行子像素输入数据信号;在第一晶体管T1开启时,来自第二数据线142的信号输入端的第二数据信号通过第一数据线141传输至与第二发光器件A电连接的像素驱动电路中。
以上所述,仅为本公开的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,想到变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以所述权利要求的保护范围为准。
