具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。并且在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互组合。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本公开保护的范围。
除非另外定义,本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面 列举的元件或者物件及其等同,而不排除其他元件或者物件。
需要注意的是,附图中各图形的尺寸和形状不反映真实比例,目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。
在现有技术中,特别是大尺寸显示装置,比如,65英寸(inch)~110英寸(inch)的电视(Television,TV),本发明人根据其相关参数,比如,布线金属类型、布线金属线宽、掩膜板(Mask)工艺条件等,确定显示屏幕不同位置的数据传输线的阻抗和容抗等数据,通过模拟像素充电率,主要包括像素充电上升时间,下降时间,最终确定有效充电时间,并确定像素充电率与显示屏幕位置坐标关系,并根据像素透过率等数据确定显示亮度与屏幕位置坐标的关系。结合图1和图2所示,其中,图1为显示近端充电模拟的示意图,图2为显示远端充电模拟的示意图,如图1所示,显示近端走线短阻抗小,耦合电容小,负载小,根据信号传输延迟时长与阻抗容抗的关系式:t=RC,其中,t表示信号传输延迟时长,R表示阻抗,C表示容抗,可知,显示近端中,数据传输上升时长t3比下降时长t4小,充电时长t5较长;如图2所示,显示远端走线长阻抗大,耦合电容大,负载大,信号传输延迟时长大,数据传输上升时长t3’和下降时长t4’都比显示近端较大,t3’>t3,t4’>t4,在数据传输周期一定时,即T1=T1’,其中,t2=t2’,可知,t5’<t5,即显示远端相较于显示近端来说充电时长较小,像素充电不足,从显示效果上来说,表现为面板显示近端亮,远端暗,画面均一性差。
鉴于此,本公开实施例提供了一种显示面板、显示装置及其调试方法,用于避免面板远端和近端阻容负载(RC Loading)差异所致的充电不均,保证画面均一性。
如图3所示为本公开实施例提供的一种显示面板的结构示意图,所述显示面板包括:
衬底基板1,所述衬底基板1包括显示区A和围绕所述显示区A的非显示区B,所述非显示区B包括位于所述显示区A一侧的绑定区C;
多个子像素2,位于所述显示区A,所述多个子像素2的像素开口区的面积沿所述绑定区C指向所述显示区A的方向呈增大趋势。
在本公开实施例中,所述衬底基板1可以是玻璃基基板、还可以是硅基基板,还可以是柔性基板等,在此不做限定。所述衬底基板1包括显示区A和围绕所述显示区A的非显示区B,所述非显示区B包括位于所述显示区A一侧的绑定区C,所述显示区A、所述非显示区B和所述绑定区C的其中一种分布示意图可以是如图3中所示的情况,还可以是如图4所示的情况,当然,可以根据实际应用需要来设置所述显示区A、所述非显示区B和所述绑定区C的具体分布情况,在此不做详述。
而且,所述显示面板包括位于所述显示区A的多个子像素2,所述多个子像素2阵列排布在所述衬底基板1上,关于所述多个子像素2的数目可以根据实际应用中所述显示面板的具体尺寸大小、像素分辨率大小、以及单个子像素的尺寸大小来设置,在此不做限定。
仍结合图3所示,所述多个子像素2的像素开口区的面积沿所述绑定区C指向所述显示区A的方向呈增大趋势,可以是所述多个子像素2的像素开口区的面积逐行呈逐渐增大的趋势,还可以是所述多个子像素2的像素开口区的面积呈部分增大的趋势,还可以是按照所述多个子像素2沿所述绑定区C指向所述显示区A的方向所分区域呈增大的趋势,在此不做限定。其中,箭头X所示的方向为所述绑定区C指向所述显示区A的方向。以所述多个子像素2的像素开口区的面积逐行呈逐渐增大的趋势为例,比如,L1行子像素与所述绑定区C之间的距离为h1,L1行子像素中各子像素的像素开口区的面积为s1,L2行子像素与所述绑定区C之间的距离为h2,L2行子像素中各子像素的像素开口区的面积为s2,其中,h1<h2,s1<s2,如此一来,所述显示区A中背离所述绑定区C越远的子像素的像素开口区的面积越大,其对应位置处的像素透过率较高,相应地弱化了其对应位置处的阻容负载较大对画面均一性所带来的负面影响,保证了显示面板的画面均一性。
在本公开实施例中,如图5所示为显示面板的其中一种结构示意图,具 体来讲,每个所述子像素所占用区域包括像素开口区和围绕所述像素开口区的遮光区,且每个所述子像素所占用区域的面积相同,在所述像素开口区设置色阻3,在所述遮光区设置遮光部4,在沿所述绑定区C指向所述显示区A的方向,每个所述子像素的所述遮光部4的宽度呈减小趋势。
在具体实施过程中,所述色阻3可以包括红色色阻、蓝色色阻和绿色色阻,所述色阻3还可以包括红色色阻、蓝色色阻、绿色色阻和白色色阻,从而实现了所述显示面板多种颜色间的混色,保证了显示品质。在实际应用中,可以根据实际需要来设置所述色阻3,在此不做详述。此外,位于所述遮光区的所述遮光部4可以是黑矩阵(Black Matrix),有效避免相邻两子像素间混光,保证了显示品质。
而且,在沿所述绑定区C指向所述显示区A的方向,每个所述子像素的所述遮光部4的宽度呈减小的趋势,可以是每个所述子像素的所述遮光部4的宽度逐行呈逐渐减小的趋势,还可以是每个所述子像素的所述遮光部4的宽度呈部分减小的趋势,还可以是每个所述子像素的所述遮光部4的宽度按照沿所述绑定区C指向所述显示区A的方向所分区域呈减小的趋势,在此不做限定。如此一来,在每个所述子像素所占区域的面积相同时,沿所述绑定区C指向所述显示区A的方向,每个所述子像素的像素开口区的面积呈增大的趋势,如此一来,所述显示区A中背离所述绑定区C越远的子像素的像素开口区的面积越大,其对应位置处的像素透过率较高,相应地弱化了其对应位置处的阻容负载较大对画面均一性所带来的负面影响,保证了显示面板的画面均一性。
在本公开实施例中,如图6所示为所述显示面板的其中一种结构示意图,具体来讲,所述显示区A包括交叉设置的数据线D和栅线G;
所述绑定区C设置在所述数据线D延伸方向的一侧,所述遮光部4中用于遮挡所述栅线G的部分沿所述数据线D延伸方向的宽度呈减小趋势。
在具体实施过程中,在所述显示区A、所述非显示区B和所述绑定区C按照图3所示的位置进行分布时,即所述绑定区C设置在所述数据线D延伸 方向的一侧,所述遮光部4可以按照图6来设置,具体地,所述遮光部4中用于遮挡所述栅线G的部分沿所述数据线D延伸方向的宽度呈减小趋势,如图6所示,所述遮光部4中用于遮挡所述栅线G的部分沿所述数据线D延伸方向的宽度,沿所述绑定区C指向所述显示区A的方向呈逐行减小的趋势,比如,与所述绑定区C间相距z1的遮光部4的宽度为w1,与所述绑定区C间相距z2的遮光部4的宽度为w2,其中,z1<z2,w1>w2,如此一来,保证了沿所述绑定区C指向所述显示区A的方向所述像素开口区的面积呈增大趋势的设计,进而保证了画面均一性。
在本公开实施例中,如图7所示为所述显示面板的其中一种结构示意图,具体来讲,所述显示区A包括交叉设置的数据线D和栅线G;
所述绑定区C设置在所述栅线G延伸方向的一侧,所述遮光部4中用于遮挡所述数据线D的部分沿所述栅线G延伸方向的宽度呈减小趋势。
在具体实施过程中,在所述显示区A、所述非显示区B和所述绑定区C按照图4所示的位置进行分布时,即所述绑定区C设置在所述栅线G延伸方向的一侧,所述遮光部4可以按照图7来设置,具体地,所述遮光部4中用于遮挡所述数据线D的部分沿所述栅线G延伸方向的宽度呈减小趋势,如图7所示,所述遮光部4中用于遮挡所述数据线D的部分沿所述栅线G延伸方向的宽度,沿所述绑定区C指向所述显示区A的方向呈逐行减小的趋势,如此一来,保证了沿所述绑定区C指向所述显示区A的方向所述像素开口区的面积呈增大趋势的设计,进而保证了画面均一性。
在本公开实施例中,在沿垂直于所述绑定区C指向所述显示区A的方向,每个所述子像素的所述遮光部4的宽度均相同。
在具体实施过程中,仍结合图5所示,在沿垂直于所述绑定区C指向所述显示区A的方向,每个所述子像素的所述遮光部4的宽度均相同,如此一来,简化了对所述遮光部4的图案的制作工艺,降低了所述显示面板的制作成本。
在本公开实施例中,如图8所示为所述显示面板的其中一种结构示意图, 具体来讲,所述显示区A沿所述绑定区C背离所述显示区A的方向分为多个子显示区,同一所述子显示区内的各个子像素的像素开口区的面积均相同,不同所述子显示区的像素开口区的面积沿所述绑定区指向所述显示区的方向逐渐增大。
在具体实施过程中,所述显示区A沿所述绑定区C背离所述显示区A的方向分为多个子显示区,所述多个子显示区的数目可以根据所述显示面板的尺寸大小来划分,可以是将所述显示区沿所述绑定区C背离所述显示区A的方向均等划分,还可以是按照其他条件来划分,在此不做限定。同一所述子显示区内的各个子像素的像素开口区的面积均相同,从而保证了同一所述子显示区内显示的均匀性,不同所述子显示区的像素开口区的面积沿所述绑定区C指向所述显示区A的方向逐渐增大,以图8所示,所述显示区A沿所述绑定区C背离所述显示区A的方向分为a1、a2和a3在内的三个子显示区,在a1子显示区内,各个子像素的像素开口区的面积均为S1,在a2子显示区内,各个子像素的像素开口区的面积均为S2,在a3子显示区内,各个子像素的像素开口区的面积均为S3,其中,S1<S2<S3。如此一来,在保证同一子显示区内显示均一性的同时,保证了沿所述绑定区C指向所述显示区A的方向所述像素开口区的面积呈增大趋势的设计,进而保证了画面均一性。
在本公开实施例中,如图9所示为所述显示面板的其中一种结构示意图,具体来讲,所述显示区A沿所述绑定区C背离所述显示区A的方向分为多个子显示区,同一所述子显示区内的各个子像素的像素开口区的面积沿所述绑定区指向所述显示区的方向逐渐增大。
在具体实施过程中,除了可以按照图8所示的方式对不同子显示区的像素开口区的面积进行设计之外,还可以采用图9所示的方式对不同显示区的像素开口区的面积进行设计,同一所述子显示区内的各个子像素的像素开口区的面积沿所述绑定区C指向所述显示区A的方向逐渐增大,如此一来,保证了同一所述子显示区内各行逐渐像素开口区面积的平滑过渡,避免因两行子像素的像素开口区面积相差较大导致显示品质较差,从而保证了显示均一 性。
基于同一公开构思,如图10所示,本公开实施例还提供了一种显示装置,所述显示装置包括:
背光模组10;
位于所述背光模组10出光侧的如上面所述的显示面板20。
在具体实施过程中,所述显示面板20可以是液晶显示面板,所述液晶显示面板可以是高级超维场转换(Advanced Super Dimension Switch,ADS)模式的显示面板,此外,该所述背光模组10可以为相关技术中的设计,在此不再详述,而且,显示装置解决问题的原理与前述显示面板20相似,因此该显示装置的实施可以参见前述显示面板20的实施,重复之处不再赘述。
在具体实施过程中,本公开实施例提供的显示装置可以为如图10所示的电视机,当然,本公开实施例提供的显示装置还可以为手机、平板电脑、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的,在此就不做赘述,也不应作为对本公开的限制。
基于同样的公开构思,如图11所示,本公开实施例还提供了一种如图10所示的显示装置的调试方法,包括:
S101:向所述显示面板输入一纯色画面;
S102:按照所述绑定区指向所述显示区的方向,向所述背光模组与所述显示区中各个子像素对应的区域加载呈减小趋势的驱动电压,以使各个子像素之间的亮度差值小于预设阈值。
在具体实施过程中,步骤S101至步骤S102的具体实现过程如下:
首先,向所述显示面板输入一纯色画面,所述纯色画面可以是最高灰阶的纯色画面,比如,灰阶为255的纯绿色画面,然后,在所述显示面板显示所述纯色画面之前,按照所述绑定区C指向所述显示区A的方向,向所述背光模组10与所述显示区A中各个子像素对应的区域加载呈减小趋势的驱动电压,以使各个子像素之间的亮度差值小于预设阈值,其中,所述预设阈值可 以为人眼分辨率的阈值,人眼无法分辨出两子像素之间的亮度差异。下面举个具体的例子来说明驱动电压的设置情况,比如,子像素sp1与所述绑定区C之间的距离为d1,子像素sp2与所述绑定区C之间的距离为d2,向所述背光模组10中与子像素sp1对应的区域加载的驱动电压为V1,向所述背光模组10中与子像素sp2对应的区域加载的驱动电压为V2,其中,d1<d2,V1<V2,从而弱化了子像素sp2对应位置处的阻容负载比子像素sp1对应位置处的阻容负载大,对画面均一性所带来的负面影响,保证了显示面板的画面均一性。此外,除了按照所述绑定区C指向所述显示区A的方向,向所述背光模组10与所述显示区A中各个子像素对应的区域加载呈减小趋势的驱动电压的同时,还可以对相应位置的像素开口面积按照图3至图9所示的方式进行设置,最大程度上保证显示装置的画面均一性,保证显示品质。
在本公开实施例中,所述显示区A沿所述绑定区C背离所述显示区A的方向还可以分为多个子显示区,步骤S102:按照所述绑定区指向所述显示区的方向,向所述背光模组10与所述显示区中各个子像素对应的区域加载呈减小趋势的驱动电压,包括:
沿所述绑定区指向所述显示区的方向,向所述背光模组10与各个子显示区对应的区域加载逐渐减小的驱动电压,其中,所述背光模组与同一所述子显示区对应的区域所加载的驱动电压为相同电压。
在具体实施过程中,可以以所述多个子显示区中的其中一个子显示区为目标子显示区,沿所述绑定区C指向所述显示区A的方向,向所述背光模组10与各个子显示区对应的区域加载逐渐减小的驱动电压,从而将除所述目标子显示区之外的其它子显示区的亮度调整至与目标子显示区间的亮度差值小于预设阈值,保证了各个子显示区之间的亮度均一性,进而保证了所述显示装置的显示品质。此外,所述背光模组10中与同一子显示区对应的区域加载相同的驱动电压,从而简化了同一子显示区中与所述背光模组10对应的区域的驱动控制,降低了画面均一性调整的成本。
在具体实施过程中,所述背光模组10可以是采用直下式LED背光,通 过背光分区调整(Local Dimming)来实现对各个分区背光亮度的补偿,进而实现对画面的显示均一性的调整,如图12所示为所述背光模组10的其中一种结构示意图,所述背光模组10可以包括系统级芯片(System on Chip,SOC)、微控制单元(Microcontroller Unit,MCU)和LED驱动芯片(Driver)三部分,通过SOC和MCU对输出给所述背光模组10对应区域的LED驱动芯片的信号进行处理,通过提高背离所述绑定区C的LED驱动芯片的驱动电压和驱动电流,从而提高相应区域位置的显示亮度,通过降低靠近素数绑定区C的LED驱动芯片的驱动电压和驱动电流,从而降低相应区域位置的显示亮度,进而保证了画面的显示均一性。其中,图12中示意出了所述显示区A划分为两个分区时,通过SOC和MCU对所述背光模组10与其中一个分区对应的LED驱动芯片1的信号进行处理,以及对所述背光模组10与另外一个分区对应的LED驱动芯片2的信号进行处理的情况,当然,在实际应用中还可以根据所述显示区A的实际分区情况来对相应分区的LED驱动芯片的驱动电压和驱动电流进行控制,在此不再详述。
此外,在本公开实施例中,将所述显示区A沿背离所述绑定区C的方向分为多个子显示区,可以根据背光亮度、像素开口率、透过率等数据进行模拟,得到显示亮度与屏幕位置关系,然后,根据相关模拟数据,将所述显示装置中的显示面板沿所述显示区A背离所述绑定区C的方向(可以是沿数据线D的延伸方向)进行分区,以相邻两个分区亮度差异小于人眼分辨率为基准,不会造成明显的分区差异。若人眼在某亮度区间最小分辨亮度为△L,所述显示区A距离所述绑定区C最近的子像素的亮度,与所述显示区A距离所述绑定区C最远的子像素的亮度之间的差值为L,则分区个数可以是N≥L/△L+1,也就是说,所述显示区A中亮度差异大小决定分区个数。
在具体实施过程中,在将所述显示区A分为所述多个子显示区之后,如图13所示,可以以所述多个子显示区中中间分区N区位置模拟亮度数据为基准,将相邻分区分别进行亮度补偿设计,可以是根据显示亮度与像素开口区的面积的对应关系,一般为线性对应关系,对靠近所述绑定区C的分区(比 如,N-1区、N-2区、……、1区)相对中间分区N区降低显示亮度,比如,相对中间分区N区的像素开口区的面积,降低靠近所述绑定区C的分区的像素开口区的面积;对背离所述绑定区C的分区(比如,N+1区、N+2区、……、2N区)相对中间分区N区增大显示亮度,比如,相对中间分区N区的像素开口区的面积,增大背离所述绑定区C的分区的像素开口区的面积,从而保证所述显示区A中各分区显示亮度一致,保证了画面均一性,提高了显示品质。
在制作如图3所示的所述显示面板的过程中,可以通过改变掩膜板,来调整各个区域内像素开口区的面积,比如,所述显示面板中的显示基板采用子像素均一开口率设计,对所述显示面板中的与所述显示基板相对的对向基板中的黑矩阵,按照各个区域内子像素的像素开口区的面积要求,采用相应的掩膜板,可以是靠近所述绑定区C的遮光部4的线宽较大,远离所述绑定区C的遮光部4的线宽减小,从而实现了对不同位置处子像素的像素开口区的面积的针对性调整。
而且,在具体实施过程中,还可以通过调整其它工艺条件来实现对所述显示面板中不同位置的子像素的像素开口区的面积的调整,比如,通过控制固化机台温度,不同位置的固化温度,以及所述对向基板中彩膜材料固化程度与线宽的相互对应关系,实现对所述遮光部4的宽度的调整,最终实现对子像素的像素开口区的面积的调整,此外,在将所述显示区A分为多个子显示区时,还可以通过控制不同分区曝光强度、曝光量、显影等工艺条件来对所述遮光部4的宽度进行调整。以固化温度为例,可以对固化机台各部分温度进行分区控制,需要高像素开口区的面积的子显示区,降低机台固化温度,从而降低所述遮光部4的宽度。当然,还可以根据实际应用需要来采用相应的工艺条件,来对各子像素的像素开口区的面积的大小进行调整,在此不再详述。
尽管已描述了本公开的优选实施例,但本领域内的技术人员一旦得知了基本创造性概念,则可对这些实施例作出另外的变更和修改。所以,所附权 利要求意欲解释为包括优选实施例以及落入本公开范围的所有变更和修改。
显然,本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样,倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
