Description

一种显示面板的点灯治具以及点灯测试方法
【技术领域】
本发明涉及显示技术领域,特别是涉及一种显示面板的点灯治具以及点灯测试方法。
【背景技术】
显示面板发展越来越多元化,人们对手机的需求越来越苛刻。手机功耗最大的部分为显示屏,降低手机屏的能耗是各家面板厂商需要考虑的主要方面。RGBW技术就是在原有的RGB三原色上增加了W白色子像素,成为四色型像素设计。采用这种方式,能够大幅度提升了液晶面板的透光率,在显示相同亮度的画面时,其耗电量更低。而相同功耗的情况下,亮度大幅提高,这使得画面层次更加分明,画面更通透。
然而采用WRGB面板需要降低面板的Flicker、DC残留等问题,需要对WRGB面板设定特定的画面显示方式。
在WRGB面板的特定画面显示方式下,对于某些画面是最重载的,这个时候面板的错充,充电不足均能显示出来,尤其是在WRGB面板的Cell点灯下,在制程变异比较大,及金属走线和跳线处电阻增大,能在特定画面下看到面板的错冲和充电不足。
【发明内容】
本发明主要解决的技术问题是提供一种显示面板的点灯治具以及点灯测试方法,能够避免在数据信号延迟的情况下,对其他子像素进行错充,影响点灯测试的效果。
为解决上述技术问题,本发明采用的一个技术方案是:提供一种显示面板的点灯治具,包括:信号发生器,用于产生多路控制信号以及第一数据信号;控制器,连接信号发生器,用于在控制信号的有效信号与第一数据信号的有效信号同时作用时,点亮显示面板中相应行的与控制信号对应的子像素;其中,多路控制信号分别与每列像素中的多个子像素对应;其中,在每个周期中,对应需点亮子像素的控制信号的有效信号与第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离第一数据信号的有效信号一设定时间段。
为解决上述技术问题,本发明采用的另一个技术方案是:提供一种显示面板的点灯测试方法,包括:将栅极信号输入至显示面板的栅极信号输入端;将多路控制信号以及第一数据信号输入至控制器,以使控制器在控制信号的有效信号与第一数据信号的有效信号同时作用时,点亮显示面板中相应行的与控制信号对应的子像素;其中,多路控制信号分别与每列像素中的多个子像素对应;其中,在每个周期中,对应需点亮子像素的控制信号的有效信号与第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离第一数据信号的有效信号一设定时间段。
本发明的有益效果是:区别于现有技术的情况,本发明提供的显示面板的点灯治具包括:信号发生器,用于产生多路控制信号以及第一数据信号;控制器,连接信号发生器,用于在控制信号的有效信号与第一数据信号的有效信号同时作用时,点亮显示面板中相应行的与控制信号对应的子像素;其中,多路控制信号分别与每列像素中的多个子像素对应;其中,在每个周期中,对应需点亮子像素的控制信号的有效信号与第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离第一数据信号的有效信号一设定时间段。通过上述方式,采用特殊的控制信号和数据信号的时序设计,可以避免在数据信号延迟的情况下,对其他子像素进行错充,影响点灯测试的效果。

图5是本发明提供的显示面板的点灯治具另一实施例的结构示意图;
图6是本发明体用的显示面板的点灯测试方法一实施例的流程示意图。
【具体实施方式】
参阅图1,图1是本发明提供的显示面板的点灯治具一实施例的结构示意图,该点灯治具包括信号发生器11和控制器12。
信号发生器11,用于产生多路控制信号以及第一数据信号。
在本实施例中,以四路控制信号为例,该四路控制信号分别为:C1、C2、C3以及C4,第一数据信号为S1。
控制器12,连接信号发生器11,用于在控制信号的有效信号与第一数据信号的有效信号同时作用时,点亮显示面板中相应行的与控制信号对应的子像素;其中,多路控制信号分别与每列像素中的多个子像素对应。
其中,控制信号的有效信号和第一数据信号的有效信号同时作用是指在控制信号和第一数据信号能够产生一数据信号,来点亮对应的子像素。例如,C1的有效信号和S1的有效信号同时作用,产生D1信号,能够点亮相应的子像素。
下面以一个具体的例子对控制信号和第一数据信号进行说明。
如图2所示,控制器12中包括多个开关管,控制信号通入每个开关管的栅极以控制开关管的导通和断开,在相应开关管导通时,第一数据信号S1能够通入相应的子像素。进一步,若在相应开关管导通,并且刚好此时第一数据信号为高电平,则点亮相应的子像素。
如图3所示,图3给出了一种RGBW四色像素的排列方式,其中,可以认为一行的四个子像素为一个像素单元,也可以将一行相邻的两个和下一行对应的两个作为一个像素单元,这里不作要求。另外,RGBW四色的排列顺序也是任意的,本实施例的排列方式仅作举例。
值得注意的是,图3示出的像素排列方式仅仅是局部的,4行*4列子像素形成一个像素单元,第一行依次为G、B、R、W,第二为依次R、W、G、B,第三行依次为G、R、B、W,第四行依次为B、W、G、R。而其他像素单元均为该4行*4列的像素单元相同。
在本实施例中,给出了一种控制信号和第一数据信号的时序方式,如图4所示。
其中,第一数据信号S1中每个周期的有效信号,位于每个周期时间长度中的相同时间位置。在每个周期中,对应需点亮子像素的控制信号的有效信号与第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离第一数据信号的有效信号一设定时间段。
下面结合图3和图4对本实施例进行详细说明:
在第一周期中,即点亮第一行的R子像素,由于R子像素位于第三个,因此,C3的高电平与S1的高电平对应,即点亮第一行的R子像素。而此时,C1、C2、C4的高电平时间延迟于C3,使得S1即使有延迟,也不会在第一个子像素、第二个子像素、第四个子像素打开时,对其进行充电。
在第二周期中,即点亮第二行的R子像素,由于R子像素位于第一个,因此,C1的高电平与S1的高电平对应,即点亮第二行的R子像素。而此时,C2、C3、C4的高电平时间延迟于C1,使得S1即使有延迟,也不会在第二个子像素、第三个子像素、第四个子像素打开时,对其进行充电。
在第三周期中,即点亮第三行的R子像素,由于R子像素位于第二个,因此,C2的高电平与S1的高电平对应,即点亮第三行的R子像素。而此时,C1、C3、C4的高电平时间延迟于C2,使得S1即使有延迟,也不会在第一个子像素、第三个子像素、第四个子像素打开时,对其进行充电。
在第四周期中,即点亮第四行的R子像素,由于R子像素位于第四个,因此,C4的高电平与S1的高电平对应,即点亮第四行的R子像素。而此时,C1、C2、C3的高电平时间延迟于C4,使得S1即使有延迟,也不会在第一个子像素、第二个子像素、第三个子像素打开时,对其进行充电。
可选的,第一数据信号中每个周期的有效信号,位于每个周期时间长度中的相同时间位置。例如,第一数据信号可以在每个周期的开始阶段提供一时间长度的高电平信号。在其他实施例中,也可以在一个周期中的其他时间位置提供一高电平信号。
可选的,上述延迟的设定时间是可以根据第一数据信号S1的延迟程度来任意设置,应该保证在第一数据信号S1延迟时,不点亮的子像素对应的控制信号不为高电平。例如,设定时间段大于第一数据信号中有效信号的时间长度。
通过上述方式,采用特殊的控制信号和数据信号的时序设计,可以避免在数据信号延迟的情况下,对其他子像素进行错充,影响点灯测试的效果。
参阅图5,图5是本发明提供的显示面板的点灯治具另一实施例的结构示意图。
其中,控制器包括多个多路选通器(Demux),每个多路选通器用于接收N路控制信号和第一数据信号,以点亮显示面板中相应行的N列子像素中与控制信号对应的子像素;其中,N为正整数。
举例而言,本实施例提供的Demux为四路,一个Demux用于向四列子像素提供数据信号。
可以理解的,结合上述图3和图4的实施例,在数据信号相同的情况下:
在第一周期中,即点亮第一行中每个像素单元的R子像素,由于R子像素位于每个像素单元的第三个,因此,C3的高电平与S1的高电平对应,即点亮第一行的所有R子像素。而此时,C1、C2、C4的高电平时间延迟于C3,使得S1即使有延迟,也不会在每个像素单元的第一个子像素、第二个子像素、第四个子像素打开时,对其进行充电。
可选的,如图5所示,在又一实施例中,信号发生器产生两个波形相反的数据信号,即第一数据信号S1和第二数据信号S2,控制器还用于在第一数据信号和第二数据信号之中择一作为点亮子像素的数据信号。
例如,可以采用第一数据信号点亮显示面板中一半子像素,采用第二数据信号点亮显示面板中另一半子像素。具体举例而言,总共有100个Demux,则可以在左边的50个Demux中通入第一数据信号,在右边的50个Demux中通入第二数据信号。
参阅图6,图6是本发明体用的显示面板的点灯测试方法一实施例的流程示意图,该方法包括:
S61:将栅极信号输入至显示面板的栅极信号输入端。
S62:将多路控制信号以及第一数据信号输入至控制器,以使控制器在控制信号的有效信号与第一数据信号的有效信号同时作用时,点亮显示面板中相应行的与控制信号对应的子像素;其中,多路控制信号分别与每列像素中的多个子像素对应。
可以理解的,点灯测试和显示面板的显示原理类似,其栅极依然可以按照现有的逐行扫描、隔行扫描、正反向扫描等方式,只是将数据信号输入端通入的数据信号换成了本实施例中提供的数据信号(例如第一数据信号S1或第二数据信号S2)。
其中,在每个周期中,对应需点亮子像素的控制信号的有效信号与第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离第一数据信号的有效信号一设定时间段。
本实施例提供的显示面板的点灯测试方法与上述实施例中的点灯治具原理相同,采用了类似的技术方案,因此这里不再赘述。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。

    所述控制器包括多个多路选通器,每个多路选通器用于接收N路控制信号和所述第一数据信号,以点亮所述显示面板中相应行的N列子像素中与所述控制信号对应的子像素;其中,N为正整数。
  10. 根据权利要求9所述的点灯治具,其中,
    所述显示面板为RGBW四色显示面板,所述多路选通器用于接收四路控制信号和所述第一数据信号,以点亮所述显示面板中相应行的四列子像素中与所述控制信号对应的子像素。
  11. 根据权利要求10所述的点灯治具,其中,
    4行*4列子像素形成一个像素单元,第一行依次为G、B、R、W,第二为依次R、W、G、B,第三行依次为G、R、B、W,第四行依次为B、W、G、R。
  12. 根据权利要求8所述的点灯治具,其中,
    所述信号发生器还用于产生第二数据信号;
    所述控制器还用于在所述第一数据信号和所述第二数据信号之中择一作为点亮子像素的数据信号;其中,所述第一数据信号和第二数据信号波形相反。
  13. 根据权利要求12所述的点灯治具,其中,
    所述控制器还用于采用所述第一数据信号点亮所述显示面板中一半子像素,采用所述第二数据信号点亮所述显示面板中另一半子像素。
  14. 根据权利要求8所述的点灯治具,其中,
    所述有效信号为高电平信号。
  15. 根据权利要求8所述的点灯治具,其中,
    所述第一数据信号中每个周期的有效信号,位于每个周期时间长度中的相同时间位置。
  16. 根据权利要求8所述的点灯治具,其中,
    所述设定时间段大于所述第一数据信号中有效信号的时间长度。
  17. 一种显示面板的点灯测试方法,其中,包括:
    将栅极信号输入至显示面板的栅极信号输入端;
    将多路控制信号以及第一数据信号输入至控制器,以使所述控制器在所述控制信号的有效信号与所述第一数据信号的有效信号同时作用时,点亮所述显示面板中相应行的与所述控制信号对应的子像素;其中,所述多路控制信号分别与每列像素中的多个子像素对应;
    其中,在每个周期中,对应需点亮子像素的控制信号的有效信号与所述第一数据信号的有效信号的时间位置相同,剩余控制信号的有效信号的时间位置距离所述第一数据信号的有效信号一设定时间段。
