本发明的实施方式
为使本申请的目的、技术方案及效果更加清楚、明确,以下参照附图并举实施例对本申请进一步详细说明。应当理解,此处所描述的具体实施例仅用以 解释本申请,并不用于限定本申请。
如图1和图2所示,本申请的实施例提供一种显示模组1000,包括显示面板1以及电路板,所述电路板包括电性连接于所述显示面板1的驱动芯片8。所述显示面板1可以是LCD显示面板,也可以是OLED显示面板。本实施例中,所述显示面板1为LCD显示面板。
所述显示面板1包括显示区DA和非显示区NDA。所述显示区DA可以是用于设置显示图像的子像素的区域。所述非显示区NDA可以是用于设置为子像素的像素驱动电路提供驱动信号的驱动单元如栅极驱动电路,以及用于设置为所述驱动单元提供信号的一些走线的区域。在所述非显示区NDA内,一般没有设置用于显示的子像素。所述非显示区NDA可以设置在所述显示区DA的至少一侧,以至少部分地围绕所述显示区DA。所述非显示区NDA包括相对的第一区NDA1和第二区NDA2。
所述显示面板1包括多个数据线10、多个扫描线11、多个子像素SPX,以及中和电路13。
多个数据线10,沿列方向延伸,至少部分位于所述显示区DA内,且通过所述第一区NDA1内的解复用电路MUX电性连接于所述驱动芯片8。所述解复用电路MUX包括多个薄膜晶体管,可以减少所述驱动芯片的数据端子的数量。
多个扫描线11,沿行方向延伸,至少部分位于所述显示区DA内,且通过位于所述非显示区NDA内的栅极驱动电路GDC电性连接于所述电路板。多个所述扫描线11与多个所述数据线10围成多个子像素区域SPA。
多个子像素SPX,位于多个所述子像素区域SPA内。所述子像素SPX为显示面板1中的最小可控发光单元,可以包括像素驱动电路和由像素驱动电路驱动的液晶盒。所述像素驱动电路电性连接于对应的所述扫描线11以及对应的所述数据线10。所述像素驱动电路可以包括至少一薄膜晶体管,所述薄膜晶体管的栅极与多个所述扫描线11同层设置且材料相同,所述薄膜晶体管的源极和漏极与多个所述数据线10同层设置且材料相同。对于OLED显示面板来说,所述子像素SPX可以包括像素驱动电路和由像素驱动电路驱动的有机发光器件。
所述中和电路13位于所述第二区NDA2内,这样,可以减少第一区NDA1(即下边框)的宽度。所述中和电路13包括多个薄膜晶体管130,多个所述薄膜晶体管130与所述显示区DA内的薄膜晶体管同层设置,这样,可以将所述中 和电路13集成在阵列基板内。
每一所述薄膜晶体管130的源极和漏极电性连接于两所述数据线10,且与相邻的两所述薄膜晶体管130电性连接的所述数据线10不同,使得多个所述薄膜晶体管130的源极和漏极作为所述中和电路13的至少两所述耦接端138,电性连接于至少两所述数据线10。这样,可以通过一个所述薄膜晶体管130实现对两所述数据线10上的电压的中和。示例性地,多个所述子像素SPX采用列反转的方式进行驱动,使得同列的所述子像素SPX的极性相同,相邻两列的所述子像素SPX的极性相反。每一所述薄膜晶体管130的所述源极和所述漏极分别连接于极性相反的相邻两列的所述子像素SPX对应的两所述数据线10。这样,在将极性相反的相邻两列的所述子像素SPX对应的两数据线10的电压进行中和以得到中间值之后,再被分别充电至对应的极性相反的电压,可以减少功耗。
多个所述薄膜晶体管130的栅极作为所述中和电路13的至少一控制端139,通过至少一所述控制信号线SW电性连接于所述驱动芯片8,以根据所述驱动芯片8的控制信号来控制至少两所述耦接端138之间的通断,进而控制至少两所述数据线10之间的电性连接。
至少一所述控制信号线SW位于所述非显示区NDA内,与多个所述数据线10同层设置且材料相同。每一所述控制信号线SW包括位于所述第二区NDA2内且沿所述行方向延伸的第一段SW1,自所述第一段SW1的相对两端沿所述列方向朝向所述第一区NDA1延伸的两第二段SW2,以及自两所述第二段SW2的两端相向延伸出的两第三段SW3,所述第一段SW1电性连接于多个所述薄膜晶体管130的所述栅极,两所述第三段SW3电性连接于所述驱动芯片8。这样,可以实现所述控制信号线SW的功能,且不影响其他信号线的设置。示例性地,所述控制信号线SW的材料可以包括选自钼(Mo)、铝(Al)、铂(Pt)、钯(Pd)、银(Ag)、镁(Mg)、金(Au)、镍(Ni)、钕(Nd)、铱(Ir)、铬(Cr)、钙(Ca)、钛(Ti)、钽(Ta)、钨(W)、铜(Cu)中的至少一种。所述控制信号线SW可以是单层结构或多层结构。例如,所述控制信号线SW可以形成为Ti/Al/Ti、Mo/Al/Mo、Mo/AlGe/Mo、Ti/Cu等层叠结构。
在本实施例中,在当前行所述子像素SPX被关闭之后且在下一行所述子像素SPX被开启之前,所述驱动芯片8通过至少一所述控制信号线SW输出控制信号至所述中和电路13的至少一控制端139,使得所述中和电路13的至少两所述 耦接端138连通或者断开。
请一并参阅图3,当所述驱动芯片8通过至少一所述控制信号线SW输出控制信号(如VGL信号)至所述中和电路13的至少一控制端139,所述中和电路13的至少两所述耦接端138断开,即所述显示模组1000处于常规驱动模式时,当前行所述子像素SPX对应的所述数据线10上的第一电压,直接被充电至下一行所述子像素SPX对应的所述数据线10的第二电压。
当所述驱动芯片8通过至少一所述控制信号线SW输出控制信号(如VGH信号)至所述中和电路13的至少一控制端139,所述中和电路13的至少两所述耦接端138连通,即所述显示模组1000处于中和驱动模式时,当前行所述子像素SPX对应的所述数据线10上的第一电压先被中和至第三电压,再充电至下一行所述子像素SPX对应的所述数据线10的第二电压。
因此,所述显示模组1000可以基于各种画面,根据显示模组1000在这两种驱动方式下的功耗,来决定显示模组1000的驱动方式以选择功耗最优条件,特别是在重载等画面下,可以明显降低功耗,效果显著。通过模拟仿真,当所述中和电路13开启0.2μs,所述数据线10上的电位可降低90%以上。
请参阅图4,在其他实施例中,与上述实施例不同的是:每一所述薄膜晶体管130的源极和漏极的中的一个电性连接于一个所述数据线10,每一所述薄膜晶体管130的所述源极和所述漏极的中的另一个通过对应的所述薄膜晶体管130电性连接于另一个所述数据线10。通过多个所述薄膜晶体管130实现多个所述数据线10的相互电性连接,可以实现多个数据线10上的电压的中和。示例性地,多个所述薄膜晶体管130的所述源极和所述漏极的中的另一个均接地线GND。
在其他实施例中,所述控制信号线SW可以有多路,多路所述控制信号线SW连接的所述薄膜晶体管130不同。这样,可以提升所述驱动芯片8对所述中和电路的驱动速度。
请参阅图5,本申请的实施例还提供一种驱动方法,应用于上述显示模组1000。所述驱动方法可以被显示模组1000的驱动芯片8执行,也可以被包括所述显示模组1000的显示装置的处理器,例如中央处理芯片执行。所述驱动方法包括:
步骤S1,比较第一功耗和第二功耗,所述第一功耗为从当前行所述子像 素SPX对应的所述数据线10上的第一电压充电至下一行所述子像素SPX对应的所述数据线10的第二电压的功耗,所述第二功耗为从当前行所述子像素SPX对应的所述数据线10上的第三电压充电至下一行所述子像素SPX对应的所述数据线10的所述第二电压的功耗,所述第三电压是通过对所述中和电路13的至少一所述控制端139加载有效电平,使得至少两所述耦接端138导通以对当前行所述子像素SPX对应的所述数据线10上的所述第一电压进行中和之后而得到的。
示例性地,G(n)行所述子像素SPX对应的所述数据线10上的所述第一电压分别为x 1、x 2……x m,经过电压中和后的G(n)行所述子像素SPX对应的所述数据线10上的所述第三电压分别为y 1、y 2……y m,G(n+1)行所述子像素SPX对应的所述数据线10上的所述第二电压分别为X 1、X 2……X m,基于功耗与充电电压差的平方成正比,我们可以认为,在常规驱动模式下的所述第一功耗A=(X 1-x 1) 2+(X 2-x 2) 2+……+(X m-x m) 2,在中和驱动模式下的所述第二功耗B=(X 1-y 1) 2+(X 2-y 2) 2+……+(X m-y m) 2。通过比较所述第一功耗A和所述第二功耗B的大小,即可得知所述显示模组1000在常规驱动模式和中和驱动模式下的功耗大小。
步骤S2,根据比较结果,以在当前行所述子像素SPX被关闭之后且在下一行所述子像素SPX被开启之前,发送控制信号至所述中和电路13的至少一所述控制端139以控制至少两所述耦接端138的通断。
当所述第一功耗A大于所述第二功耗B,即中和驱动模式下的显示模组1000具有更低的功耗时,在G(n)行所述子像素SPX被关闭之后且在G(n+1)行所述子像素SPX被开启之前,发送所述控制信号使得所述有效电平(例如,VGH信号)被加载至所述中和电路13的至少一所述控制端139,使得所述中和电路13的至少两所述耦接端138连通,G(n)行所述子像素SPX对应的所述数据线10上的第一电压先被中和至第三电压,再充电至G(n+1)所述子像素SPX对应的所述数据线10的第二电压。因此,可以实现低功耗。
当所述第一功耗A小于或等于所述第二功耗B,即常规驱动模式下的显示模组1000具有更低的功耗时,在G(n)行所述子像素SPX被关闭之后且在G(n+1)行所述子像素SPX被开启之前,发送所述控制信号使得无效电平(例 如,电位小于所述VGH信号的VGL信号)被加载至所述中和电路13的至少一所述控制端139,使得所述中和电路13的至少两所述耦接端138断开,G(n)行所述子像素SPX对应的所述数据线10上的第一电压直接被充电至G(n+1)所述子像素SPX对应的所述数据线10的第二电压。因此,可以实现低功耗。
本申请的实施例还提供一种显示装置,包括上述的显示模组1000、电性连接于所述显示模组1000的处理器,以及存储装置。所述存储装置用于存储程序指令,所述处理器或所述显示模组1000的所述驱动芯片用于执行所述程序指令,以实现上述驱动方法。所述存储装置可以是所述显示装置的只读存储器(ROM)和随机存取存储器(RAM),也可以是显示模组的闪存。
所述显示装置是具有显示功能的装置,示例性地,所述显示装置可以是显示视频或静止图像的装置,包括固定终端诸如电视、台式计算机、监视器、广告牌,也可以包括移动终端诸如移动电话、平板电脑、移动通信终端、电子记事本、电子书、多媒体播放器、导航仪、笔记本电脑,还可以包括穿戴式电子设备诸如智能手表、智能眼镜、虚拟现实设备、增强现实设备。
以上对本申请实施例进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请的方法及其核心思想;同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
