Description

一种显示面板的异常像素点修复方法 【技术领域】
本申请涉及显示面板技术领域,特别是涉及一种显示面板的异常像素点修复方法。
【背景技术】
随着科技的发展和进步,液晶显示器由于具备机身薄、省电和辐射低等热点而成为显示器的主流产品,得到了广泛应用。现有市场上的液晶显示器大部分为背光型液晶显示器,其包括液晶面板及背光模组(backlightmodule)。液晶面板的工作原理是在两片平行的玻璃基板当中放置液晶分子,并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向,以将背光模组的光线折射出来产生画面。
其中,薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display,TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能,目前已经逐渐占据了显示领域的主导地位。同样,薄膜晶体管液晶显示器包含液晶面板和背光模组,液晶面板包括彩膜基板(Color Filter Substrate,CF Substrate,也称彩色滤光片基板)、薄膜晶体管阵列基板(Thin Film Transistor Substrate,TFTSubstrate)和光罩(Mask),上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(LiquidCrystal,LC)。
而不管是较为落后或者较为先进的显示器,都无可避免的可能出现异常像素点的问题,特别的出现异常像素亮点的问题,而处于常亮状态的像素点将会极大的影响显示器的显示效果。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
【发明内容】
有鉴于现有技术的上述缺陷,本申请所要解决的技术问题是提供一种能够改善异常像素点问题的显示面板的异常像素点修复方法。
为实现上述目的,本申请提供了一种异常像素点修复方法,包括:
在显示面板和显示器屏幕之间设置偏光板;
在偏光板上查找并标记出异常像素点;
使用特定光线改变异常像素点处的光偏振结构。
本申请由于将修复异常像素点的工作放在偏光板处进行,而不在薄膜晶体管或者光阻处进行,如此,既能达到修复异常像素点的目的,又不会对薄膜晶体管和光阻造成无法修复的损伤;特别的,当出现异常像素亮点时,本申请的方案,可以通过特定的光线对偏光板进行照射,从而局部改变异常像素亮点处的光偏振结构,可以是减少光通量,可以是阻挡光线通过,在某些情况下,还可以是将光通量增加,或者将异常像素亮点周围的光线引导至异常像素点处,从而达到修复的目的;而且,由于相对于薄膜晶体管和光阻造成的不可逆的损伤,偏光板处有希望通过其他参数的光线将其修复至原有的光偏振结构,而即使无法修复,偏光板的更换也要容易并且便宜得多。
参照后文的说明和附图,详细公开了本申请的特定实施方式,指明了本申请的原理可以被采用的方式。应该理解,本申请的实施方式在范围上并不因而受到限制。在所附权利要求的精神和条款的范围内,本申请的实施方式包括许多改变、修改和等同。
针对一种实施方式描述和/或示出的特征可以以相同或类似的方式在一个或更多个其它实施方式中使用,与其它实施方式中的特征相组合,或替代其它实施方式中的特征。
应该强调,术语“包括/包含”在本文使用时指特征、整件、步骤或组件的存在,但并不排除一个或更多个其它特征、整件、步骤或组件的存在或附加。
【附图说明】
所包括的附图用来提供对本申请实施例的进一步的理解,其构成了说明书的一部分,用于例示本申请的实施方式,并与文字描述一起来阐释本申请的原理。显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。

为了使本技术领域的人员更好地理解本申请中的技术方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都应当属于本申请保护的范围。
现在显示器的种类越来越多,也越来越先进。
但不管是较为落后或者较为先进的显示器,都无可避免的可能出现异常像素点的问题,特别的出现异常像素亮点的问题,而处于常亮状态的像素点将会极大的影响显示器的显示效果。
图1、2所示是本申请发明人使用过一些未公开的修复异常像素亮点问题的方法示意图,参考图1、2可知,发明人使用过一些未公开的修复异常像素亮点问题的方法,例如,使用镭射光讲异常像素亮度处的薄膜晶体管(TFT)线路进行切断,如图,线路切断点A即通过截断方式将TFT线路切断,让其无法点亮 从而改善异常像素亮点的问题;或者,是通过镭射光将异常像素亮点处的光阻烧黑,如图,光阻烧黑处B即通过镭射光烧黑,使得光线无法通过,而达到改善异常像素亮点问题的目的。
但以上的方法均存在其各自的缺陷,因而本申请的发明人改进得到了如下的方案:
图3是本申请一种异常像素点修复方法的流程图,图4是本申请一种显示面板结构的简要视图,参考图1、2和3可知,本申请公开了一种异常像素点修复方法,包括步骤:
S1:在显示面板和显示器屏幕之间设置偏光板;
S2:在偏光板上查找并标记出异常像素点;
S3:使用特定光线改变异常像素点处的光偏振结构。
本申请由于将修复异常像素点的工作放在偏光板处进行,而不在薄膜晶体管或者光阻处进行,如此,既能达到修复异常像素点的目的,又不会对薄膜晶体管和光阻造成无法修复的损伤;特别的,当出现异常像素亮点时,本申请的方案,可以通过特定的光线对偏光板进行照射,从而局部改变异常像素亮点处的光偏振结构,可以是减少光通量,可以是阻挡光线通过,在某些情况下,还可以是将光通量增加,或者将异常像素亮点周围的光线引导至异常像素点处,从而达到修复的目的;而且,由于相对于薄膜晶体管和光阻造成的不可逆的损伤,偏光板处有希望通过其他参数的光线将其修复至原有的光偏振结构,而即使无法修复,偏光板的更换也要容易并且便宜得多。
LCD CELL就是LCD模组除背光模组以外的那一部分,含TFT片,偏光片,滤色片,间隔器,共通片(透明铟锡氧化物)及液晶等部件组成,LCD CELL可以理解为LCD光学膜片,或LCD光学单元,或者说可以理解为包括液晶盒、TFT片和光阻在内的组件。

该遮光部根据需要的不同,可以起到减少光通量或者是阻绝光线通过等作用。
本实施例可选的,偏光板包括设置在显示面板300的出光面的第一偏光板100和设置在显示面板300的入光面的第二偏光板200;
使用特定光线对偏光层进行处理,改变异常像素点处的光偏振结构以形成遮光部:使用特定光线对第一偏光板的偏光层进行处理,改变异常像素点处的光偏振结构以形成遮光部。例如,图中,异常像素点C,即为待修复的地方,本实施方式中,该偏光板位于显示面板和观众之间(偏光板和显示面板之间还可以设置有薄膜晶体管、光阻等),如此,在对偏光板进行光偏振结构改变的入光面,显示面板、薄膜晶体管和光阻等处的异常而导致的异常像素点的光线情况将被偏光板淡化处理,从而减少其对显示器显示效果的影响;特别的,当该异常像素点为异常像素亮点时,该减少光通量的光偏振结构改变,将能够减少亮点对于显示效果的影响,在一定程度上,达到将其修复成暗点的效果。
本实施例可选的,在偏光板上查找并标记出异常像素点的步骤包括:

本实施例可选的,特定光线包括低波长红外线。
本实施例可选的,特定光线包括低波长红外线皮秒镭射光。

本实施例可选的,在偏光板上查找并标记出异常像素点的步骤还包括:
在光阻处查找并标记出第二参考异常像素亮点;
通过第一参考异常像素亮点和第二参考异常像素亮点,查找并标记出偏光板对应的异常像素亮点。本实施方式中,该异常像素点主要指异常像素亮点,而该异常像素亮点与薄膜晶体管以及光阻的关系甚大,通过在薄膜晶体管以及光阻查找并标记出第一参考异常像素亮点和第二参考异常像素亮点,可以准确的在偏光板处查找并标记出异常像素亮点的位置,而且,由于通过对偏光板进 行局部光偏振结构改变即可改善异常像素亮点的问题,也可以避免对薄膜晶体管造成不可逆的损伤,方便日后进行修理。

在偏光板上查找并标记出异常像素亮点;
在第一基板处查找并标记出第一参考异常像素亮点;
在光阻处查找并标记出第二参考异常像素亮点;
通过第一参考异常像素亮点和第二参考异常像素亮点,验证该异常像素亮点是否正确;
正确则进入下一步,否则重新查找并标记异常像素亮点。本实施方式中,通过在第一基板处的薄膜晶体管,以及光阻处查找并标记参考异常像素亮点,辅助验证该异常像素亮点是否找对找准,避免找的不对或者范围不准等,在修复后出现,将未出现问题的像素对应的偏光板也进行光偏振结构改变的问题发生。
以上详细描述了本申请的较佳具体实施例。应当理解,本领域的普通技术人员无需创造性劳动就可以根据本申请的构思作出诸多修改和变化。因此,凡本技术领域中技术人员依本申请的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应在由权利要求书所确定的保护范围内。
