具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
为了便于理解本公开实施例,下面先简单介绍一下液晶显示装置的结构和 工作原理。
图1是一种液晶显示装置的结构示意图。如图1所示,液晶显示装置包括背光模组11和液晶面板12。背光模组11用于为液晶面板12提供均匀的背光源。液晶面板12包括阵列基板121、彩膜基板122和夹在阵列基板121和彩膜基板122之间的液晶层123。液晶面板12通过阵列基板121控制作用于液晶层123中液晶分子的电场的方向和/或大小,来控制透过液晶面板12的各个区域的光的亮度,从而显示图像。
在本公开实施例中,液晶面板为带有柔性电路板(Flexible Printed Circuit,FPC)的液晶面板,也被称为FOG(FPC on Glass)。
图2是本公开实施例提供的一种液晶显示装置的制造方法的示意图。如图2所示,该方法包括:
在步骤201中,获取多个背光模组在相同驱动条件下的亮度数据。
该步骤201中,驱动条件是指驱动电压和/或驱动电流。在相同驱动条件下的亮度数据是指,在采用相同的驱动电压和/或驱动电流驱动多个背光模组工作的情况下,测得的各个背光模组的亮度数据。
在步骤202中,将多个背光模组按照对应的亮度数据进行分组,得到N个背光组,不同背光组中的背光模组的亮度数据处于不同的亮度区间。
其中,N为大于1的整数。通过该步骤202,将多个背光模组分为至少两个背光组,同一个背光组中的背光模组的亮度数据处于同一个亮度区间,而不同的背光组中的背光模组的亮度数据处于不同的亮度区间。在本公开实施例中,不同的亮度区间是指不存在重叠范围的亮度区间。
在步骤203中,获取多个液晶面板在相同驱动条件下的透过率数据。
该步骤203中,驱动条件是指驱动电压和/或驱动电流。在相同驱动条件下的透过率数据是指,在背光模组的亮度数据一定,且采用相同的驱动电压和/或驱动电流驱动多个液晶面板工作的情况下,测得的各个液晶面板的透过率数据。
在步骤204中,将多个液晶面板按照对应的透过率数据进行分组,得到N个面板组,不同面板组中的液晶面板的透过率数据处于不同的透过率区间。
在本公开实施例中,面板组的数量与背光组的数量相等。通过该步骤204,将多个液晶面板分为至少两个面板组,同一个面板组中的液晶面板的透过率数据处于同一个透过率区间,而不同的面板组中的液晶面板的透过率数据处于不 同的透过率区间。
在步骤205中,确定背光组和面板组之间的对应关系,对应关系用于将目标背光模组与目标液晶面板匹配成对,匹配成对的目标背光模组和目标液晶面板用于组装成液晶显示装置。
其中,该对应关系为所述N个背光组按照对应的亮度区间的代表值从高到低的顺序与所述N个面板组按照对应的透过率区间的代表值从低到高的顺序一一对应。目标背光模组为多个背光模组中的任一个,目标液晶面板为目标背光模组所属的背光组对应的面板组中的一个液晶面板。
示例性地,代表值可以为上限值、下限值、中间值等。
例如,假设N个背光组分别为A1~AN,A1对应的亮度区间为(a0,a1),A2对应的亮度区间为(a1,a2)……AN对应的亮度区间为(aN-1,aN),a0至aN依次增大。N个面板组分别为B1~BN,B1对应的透过率区间为(bN-1,bN),B2对应的透过率区间为(bN-2,bN-1)……BN对应的透过率区间为(b0,b1),b0至bN依次增大。则A1与B1对应,A2与B2对应……AN与BN对应。则A1中的背光模组与B1中的液晶面板匹配,……AN中的背光模组与BN中的液晶面板匹配。
需要说明的是,本公开实施例对步骤201~202和步骤203~204的执行顺序不做限制,可以先后执行或者同步执行。
在本公开实施例中,液晶显示装置的亮度均一性用于衡量多个液晶显示装置在相同驱动条件下的亮度数据的差异大小,亮度数据差异越小,均一性越高,亮度数据差异越大,均一性越低。
在该液晶显示装置的制造方法中,通过对背光模组按照亮度数据高低分组,对液晶面板按照透过率数据高低分组,并且使N个背光组按照对应的亮度区间的代表值从高到低的顺序与所述N个面板组按照对应的透过率区间的代表值从低到高的顺序一一对应,在进行背光模组与液晶面板的匹配时,确定背光组和面板组之间的对应关系,对应关系用于将目标背光模组与目标液晶面板匹配成对。其中,目标背光模组为所述多个背光模组中的任一个,目标液晶面板为所述目标背光模组所属的背光组对应的面板组中的一个液晶面板,从而使得亮度数据较高的背光模组与透过率数据较低的液晶面板匹配成对,而亮度数据较低的背光模组与透过率数据较高的液晶面板匹配成对,按照该匹配结果将匹配成对的目标背光模组和所述目标液晶面板组装在一起,有利于减小组装得到的液晶显示 装置之间亮度数据的差异,从而提高了液晶显示装置的亮度均一性。
对于虚拟现实(Virtual Reality,VR)设备通常具有两个液晶显示装置,两个液晶显示装置分别对应人的左眼和右眼。如果一个VR设备的两个液晶显示装置的亮度数据差异过大,将很容易被用户感知到,显著影响用户的使用感受。因此,用于VR设备的液晶显示装置对于亮度数据均一性得到要求相对较高,采用本公开实施例提供的制造方法制造的液晶显示装置尤其适用于VR设备。
该制造方法适用于大批量自动化制造液晶显示装置。通过自动完成背光模组和液晶面板的分组以及将分组后的目标背光模组和目标液晶面板根据背光组和面板组之间的对应关系进行匹配贴合,可以节省大量的人工成本,同时提升了液晶显示装置的生产效率。
在一些示例中,用来分组的背光模组的数量与液晶面板的数量相同。在另一些示例中,用来分组的背光模组的数量与液晶面板的数量不同。
在一些示例中,目标背光组中的背光模组的数量与N个背光组中包含的背光模组的总数的比值等于目标面板组中液晶面板的数量与N个面板组中包含的液晶面板的总数的比值。目标背光组为所述N个背光组中的任一个,目标面板组为N个面板组中与所述目标背光组对应的面板组。
通过使目标背光组的中背光模组所占的数量比例与目标面板组中液晶面板所占的数量比例相同,这样,可以在背光模组的数量和液晶面板的数量相等的情况下,充分利用所有的背光模组和液晶面板,而在背光模组的数量和液晶面板的数量不相等的情况下,将多余的背光模组用于与下一批液晶面板进行组装或者将多余的液晶面板用于与下一批背光模组进行组装,以免造成物料的浪费。
在另一些示例中,目标背光组中的背光模组的数量与N个背光组中包含的背光模组的总数的比值不等于目标面板组中液晶面板的数量与N个面板组中包含的液晶面板的总数的比值。
为了实现目标背光组中的背光模组的数量与N个背光组中包含的背光模组的总数的比值等于目标面板组中液晶面板的数量与N个面板组中包含的液晶面板的总数的比值,有以下两种分组方式:
第一种,基于标准正态分布函数对背光模组和液晶面板进行分组。经过大量测试和统计,发现在生产条件稳定(例如生产条件相同)的情况下生产出来的多个背光模组(例如同一批次的背光模组)的亮度数据满足正态分布(即高斯分布)的规律;在生产条件稳定(例如生产条件相同)的情况下生产出来的多个液晶面 板(例如同一批次的液晶面板)的透过率数据也满足正态分布的规律,因此,可以基于标准正态分布函数对背光模组和液晶面板进行分组。
图3是本公开实施例提供的一种分组方法的过程示意图。如图3所示,该过程包括:
在步骤301中,获取多个背光模组在相同驱动条件下的亮度数据。
示例性地,可以采用辉度计(例如BM-7A)等设备对多个背光模组进行亮度测试,从而得到多个背光模组在相同驱动条件下的亮度数据。
在步骤302中,基于标准正态分布函数对背光模组进行分组,得到N个背光组。其中,不同背光组中的背光模组的亮度数据处于不同的亮度区间。不同的亮度区间之间不重叠。
背光模组的亮度数据的正态分布函数为:
Figure PCTCN2021096957-appb-000001
公式(1)中,u1为多个背光模组的亮度数据的平均值,σ1为多个背光模组的亮度数据的标准差。
由正态分布计算,可得:
Figure PCTCN2021096957-appb-000002
Figure PCTCN2021096957-appb-000003
则dx=σdn,将公式(2)转化为标准正态分布函数,可得:
Figure PCTCN2021096957-appb-000004
P函数结果表示在kσ1的情况下,符合条件的背光模组占多个背光模组总数的比例。公式(3)中,k为设定值,0<k1≤3。
根据公式(3),可以计算出不同亮度区间内的背光模组占多个背光模组的总数的比例,从而可以将多个背光模组进行分组。
在一种可能实现方式中,基于标准正态分布函数对背光模组进行分组,可以将背光模组分为2组或者3组。也即是,N等于2或者3。下面对分2组和分3组的情况分别进行说明。
当N等于2时,将亮度数据位于区间(u1-k1σ1,u1)的背光模组分为第一组,将亮度数据位于区间(u1,u1+k1σ1)的背光模组分为第二组,其中,u1为N个背 光组包含的背光模组亮度数据的平均值,k1为设定值,0<k1≤3,σ1为N个背光组包含的背光模组亮度数据的标准差。
示例性地,2≤k1≤3,例如k1=2,或者k1=2.2,或者k1=3。
当N等于3时,将亮度数据位于区间(u1-k11σ1,u1-k12σ1)的背光模组分为第一组,将亮度数据位于区间(u1-k12σ1,u1+k12σ1)的背光模组分为第二组,将亮度数据位于区间(u1+k12σ1,u1+k11σ1)的背光模组分为第三组,其中,u1为N个背光组包含的背光模组亮度数据的平均值,k11和k12均为设定值,0<k12<k11≤3,σ1为N个背光组包含的背光模组亮度数据的标准差。
示例性地,2≤k11≤3,0<k12<2。在一些示例中,k11=3,k12=0.7。
在步骤303中,获取多个液晶面板在相同驱动条件下的透过率数据。
示例性地,可以采用色彩分析仪(例如CA410)等设备对多个液晶面板进行透过率测试,从而得到多个液晶面板在相同驱动条件下的透过率数据。
在步骤304中,基于标准正态分布函数对液晶面板进行分组,得到N个面板组。其中,不同面板组中的液晶面板的透过率数据处于不同的透过率区间。
液晶面板的透过率数据的正态分布函数:
Figure PCTCN2021096957-appb-000005
公式(4)中,u2为多个液晶面板的透过率数据的平均值,σ2为多个液晶面板的透过率数据的标准差。
由正态分布计算,可得:
Figure PCTCN2021096957-appb-000006
将其转化为标准正态分布可得:
Figure PCTCN2021096957-appb-000007
P函数结果表示在kσ2的情况下,符合条件的液晶面板占多个液晶面板总数的比例。公式(6)中,k为设定值,0<k1≤3。
根据公式(6),可以计算出不同透过率区间内的液晶面板占多个液晶面板总 数的比例,从而可以将多个液晶面板进行分组。
当背光模组被分为2组时,液晶面板也被分为2组。此时,将透过率数据位于区间(u2-k2σ2,u2)的液晶面板分为第一组,将透过率数据位于区间(u2,u2+k2σ2)的液晶面板分为第二组,其中,u2为N个面板组包含的液晶面板透过率数据的平均值,k2=k1,σ2为N个面板组包含的液晶面板的透过率数据的标准差。
当背光模组被分为3组时,液晶面板也被分为3组。此时,将透过率数据位于区间(u2-k21σ2,u2-k22σ2)的液晶面板分为第一组,将透过率数据位于区间(u2-k22σ2,u2+k22σ2)的液晶面板分为第二组,将透过率数据位于区间(u+k22σ,u+k21σ)的液晶面板分为第三组,其中,u2为N个面板组包含的液晶面板透过率数据的平均值,k11=k21,k12=k22,σ2为N个面板组包含的液晶面板的透过率数据的标准差。
第二种,按照设定组数和设定比例对背光模组或液晶面板进行分组。
图4是本公开实施例提供的另一种分组方法的过程示意图。如图4所示,该过程包括:
在步骤401中,获取多个背光模组在相同驱动条件下的亮度数据。
在步骤402中,将多个背光模组按照对应的亮度数据按照第一顺序的顺序进行排序。
其中,第一顺序为从高到低或者从低到高。
在步骤403中,按照第一设定组数和第一设定比例,根据多个背光模组的排序结果,将多个背光模组进行分组。
其中,第一设定组数为背光组的数量,第一设定比例为各个背光组所包含的背光模组的数量比例。
示例性地,该步骤403包括:
第一步、根据第一设定比例和多个背光模组的总数确定对应的背光组中的背光模组的数量;
第二步、根据排序结果,连续选择对应数量的背光模组作为一个背光组。
例如,假设背光模组的数量为100个,第一顺序为从高到底,第一设定组数为2组,第一设定比例为1:1,则两个背光组中背光模组的数量均为50。那么,将排序结果中的第1~50个分到第一个背光组,第51~100个分到第二个背光组。
通过该步骤401~403,实现将多个背光模组按照在相同驱动条件下的亮度数 据进行分组,得到N个背光组,不同背光组中的背光模组的亮度数据处于不同的亮度区间。
在步骤404中,获取多个液晶面板在相同驱动条件下的透过率数据。
在步骤405中,将多个液晶面板按照对应的透过率数据按照第二顺序进行排序。
其中,第二顺序与第一顺序相反。例如,当第一顺序为从低到高时,第二顺序为从高到低。又例如,当第一顺序为从高到低时,第二顺序为从低到高。
在步骤406中,按照第二设定组数和第二设定比例,根据多个液晶面板的排序结果,将多个液晶面板进行分组。
其中,第二设定组数为面板组的数量,第二设定比例为各个面板组所包含的背光模组的数量比例,第二设定组数等于第一设定组数,第二设定比例等于第一设定比例。
该步骤406包括:第一步、根据第二设定比例和多个液晶面板的总数确定对应的面板组中的液晶面板的数量;第二步、根据排序结果,连续选择对应数量的液晶面板作为一个面板组。
通过该步骤404~406,实现将多个液晶面板按照在相同驱动条件下的透过率数据进行分组,得到N个面板组,不同面板组中的液晶面板的透过率数据处于不同的透过率区间。
需要说明的是,本公开实施例对步骤401~403与步骤404~406之间的执行顺序不做限制,可以先后执行,也可以同步执行。

由于液晶显示装置亮度的波动性是所采用的背光模组的亮度波动性和液晶面板的透过率波动性的叠加,所以如果背光模组的亮度波动性或者液晶面板的透过率波动性过大,将会导致液晶显示装置的均一性较差。通过在对多个背光模组或多个液晶面板进行分组之前,从多个背光模组中去除亮度数据超过设定亮度数据范围的背光模组或从多个液晶面板中去除透过率数据超过设定透过率数据范围的液晶面板,可以减小参与匹配的背光模组亮度或液晶面板透过率的波 动性,从而提高由其匹配成的液晶显示装置亮度的均一性。并且,有利于提高液晶显示装置的生产良率。
可选地,设定亮度数据范围为(u1-k1σ1,u1+k1σ1),其中,u1为所有背光模组亮度数据的平均值,σ1为所有背光模组亮度数据的标准差,2≤k1≤3。
可选地,设定透过率数据范围为(u2-k2σ2,u2+k2σ2),其中u2为所有液晶面板的透过率数据的平均值,σ2为所有液晶面板的透过率数据的标准差,2≤k2≤3。
需要说明的是,如果需要同时去除背光模组和液晶面板,则k1=k2。
该步骤可以与图3至图5中任一种分组方式结合。
需要说明的是,在背光模组的亮度数据波动性较小的情况下,例如亮度数据波动性小于10%的情况下,可以无需对背光模组执行该步骤。

下面通过具体示例对本公开实施例的效果进行说明。
示例一
第一步,使用BM-3A对背光模组的亮度进行测试。
1)测试前准备工作:
a)仪器聚焦:把测定角调到2°;调节目镜的调焦环,同时观测目镜,当目镜中所见的测量点(目镜中的黑点)最清晰时停止调整;调节物镜的调焦环,同时在目镜中观测被测物体,当被测物体最清晰时停止调整;选择合适的测定角(例如1°的测定角)进行测试。
b)仪器开机:打开仪器上的电源开关,仪器进入暖机状态,暖机时间一般为十五分钟。
c)选定模式:使用远程模式将仪器与电脑连接,以使测量数据传输至电脑 中的测定软件。
2)数据测定:
a)仪器进入自动测定状态并将测得的背光模组的亮度数据传输至电脑。
b)电脑根据接收到的数据进行拟合,得到如图7所示的测试结果。
图7中,横坐标表示背光模组的亮度数据,左侧纵坐标为背光模组的组数,右侧纵坐标为正态分布密度函数的值。由图7可以看出,多个背光模组的亮度数据分布符合正态分布。背光模组的亮度数据的波动小于10%。
第二步,使用CA410对液晶面板的透过率数据进行测试。
1)测试前准备工作:
a)筛选校准背光模组:挑选至少3个标准背光模组,确定不同的驱动电流下背光模组的亮度数据,根据实际需要选择透过率测试所需要的电流大小。例如,在20mA~40mA之间,每间隔5mA,测试一次背光模组的亮度数据。
b)校准CA410:采用已标定过的液晶面板的数据,对CA410进行光学校准,以保证光学标准的一致性。
2)数据测定:
a)仪器进入自动测定状态,并且将测量得到的液晶面板的亮度数据传输至电脑;
b)电脑根据液晶面板的亮度数据和标准背光模组的亮度数据的比值,拟合得到如图8所示的测试结果。
图8中,横坐标表示液晶面板的透过率数据,左侧纵坐标为液晶面板的组数,右侧纵坐标为正态分布密度函数的值。由图7可以看出,多个液晶面板的透过率数据分布符合正态分布。液晶面板的透过率数据的波动大于10%,在30%左右。
第三步,令k=2.2,将超过(u-2.2σ,u+2.2σ)的液晶面板去除。
在该示例中,测试的液晶面板的总数为559。计算得到透过率数据平均值u为1.51%,标准差σ为0.1%。即将在范围(1.29%,1.72%)之外的液晶面板去除。实际去除了6个液晶面板,实际的良率为1-6/559=98.9%。根据标准正态函数计算出的良率为98.49%。
需要说明的是,在该示例中,由于背光模组的亮度数据波动性小于10%,所以无需去除背光模组。
第四步,将背光模组按照亮度数据高低分为2个背光组,第一个背光组为 (min,u)=(53894,57000),第二个背光组为(u,max)=(57000,61581);将液晶面板按照透过率数据高低分为2个组,第一个面板组为(u-k1σ,u)=(1.29%,1.51%),第二个面板组为(u,u+k1σ)=(1.51%,1.73%);将第一个背光组的背光模组和第二个面板中的液晶面板组进行贴合组装,将第二个背光组中的背光模组与第一个面板组中的液晶面板进行贴合组装。
第一个面板组包括277个液晶面板,第二个面板组中包括276个液晶面板。
在相同的测试条件下,对采用本公开实施例的方法得到的液晶显示装置和采用随机组装的方式得到的液晶显示装置进行测试,测试结果如下表一。
表一
亮度指标 未匹配(228pcs) 匹配(373pcs)
均一性 80.36% 82.34%
波动性 -23.53%,14.2% -21.7%,11.84%
10%波动良率 88.60% 92.23%
20%波动良率 99.12% 99.73%
表一中,波动性的下限值是指所有液晶显示装置的亮度数据的最小值与所有液晶显示装置的亮度数据平均值的差值与该亮度数据平均值的比值;波动性的代表值是指所有液晶显示装置的亮度数据的最大值与所有液晶显示装置的亮度数据平均值的差值与该亮度数据平均值的比值。X%波动良率,是指在允许波动X%的情况下(即波动值小于-X%和波动值大于X%的液晶显示装置均认为不良),液晶显示装置的良率。
从表一可以看出,使用本公开实施例提供的方法得到的液晶显示装置与采用随机组装的方式得到的液晶显示装置的均一性、亮度数据范围的波动性和亮度数据的波动良率均有所改善。
示例二
第一步,使用BM-3A对背光模组的亮度进行测试。
测试条件参见示例一,得到的测试结果如图9所示。背光模组的亮度数据平均值为28266nit,波动范围+/-10。
第二步,使用CA410对液晶面板的透过率进行测试。
测试条件参见示例一,得到的测试结果如图10所示。液晶面板的透过率数据平均值为1.73%,波动范围为+/-30。
第三步,将超过(u-3σ,u+3σ)的液晶面板去除。液晶面板的良率为99.74%。
需要说明的是,在该示例中,由于背光模组的亮度数据波动范围较小,所以无需去除背光模组。
第四步,匹配方案1
将亮度数据位于区间(u1-k11σ1,u1-k12σ1)的背光模组归为低亮度背光模组,将亮度数据位于区间(u1-k12σ1,u1+k12σ1)的背光模组归为中亮度背光模组,将亮度数据位于区间(u1+k12σ1,u1+k11σ1)的背光模组归为高亮度背光模组,其中,u1为背光模组亮度数据的平均值,k11和k12均为设定值,0<k12<k11≤3,σ1为背光模组亮度数据的标准差。
将透过率数据位于区间(u2-k21σ2,u2-k22σ2)的液晶面板归为低透过率面板组,将透过率数据位于区间(u2-k22σ2,u2+k22σ2)的液晶面板归为中透过率面板组,将透过率数据位于区间(u2+k22σ,u2+k21σ)的液晶面板归为高透过率面板组,其中,u2为液晶面板透过率数据的平均值,k11=k21,k12=k22,σ2为液晶面板的透过率数据的标准差。
将分好组的背光模组和液晶面板按照高对低,中对中,低对高的方法进行匹配。
匹配方案2:
将亮度数据位于区间(u1-k1σ1,u1)的背光模组归为低亮度背光模组,将亮度数据位于区间(u1,u1+k1σ1)背光模组归为高亮度背光模组。
将透过率数据位于区间(u2-k2σ2,u2)的液晶面板归为低透过率面板组,将透过率数据位于区间(u2,u2+k2σ2)的液晶面板归为高透过率面板组。
将分好组的背光模组和液晶面板按照高对低,低对高的方法进行匹配。其中k1=k2=2或k1=k2=3。
在相同的测试条件下,对采用本公开实施例的方法得到的液晶显示装置和采用随机组装的方式得到的液晶显示装置进行测试,测试结果如下表二。
表二
Figure PCTCN2021096957-appb-000008
表二中,均一性=1-3σ/Ave,其中σ是所有液晶显示装置的亮度数据的标准差,Ave是所有液晶显示装置的亮度数据的平均值。
面板良率损失为透过率数据超出设定透过率数据范围的液晶面板的数量占所有液晶面板的总数的比例,不分档随机组合的方法中没有进行液晶面板的筛选,所以面板良率损失为0%。
从表二可以看出,无论是分三组还是分二组,液晶显示装置的亮度的均一性均明显优于不分组的情况下的液晶显示装置的亮度的均一性。
