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。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。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、 数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
本公开实施例提供一种液晶显示面板，如图1(a)、图1(b)以及图3所示，包括第一衬底基板10、第二衬底基板20以及设置在第一衬底基板10和第二衬底基板20之间的液晶层(未示意)，液晶显示面板还包括：第一电极30和第二电极40，第一电极30和第二电极40均设置在第一衬底基板10和第二衬底基板20之一靠近液晶层的一侧；第一电极30和第二电极40用于产生电场；导体50，导体50位于第一电极30和第二电极40之间，导体50用于产生磁场方向垂直于第一衬底基板10的平面和第二衬底基板20的平面的磁场。第一衬底基板10与第二衬底基板20对置，因此，二者彼此平行。
至少一些实施例中，导体50设置在第一衬底基板10或第二衬底基板20靠近液晶层的一侧。
至少一些实施例中，第一电极30和第二电极40位于同一个承载面(例如均位于图3(a)的同一个取向层60)上且与该承载面接触。
至少一些实施例中，第一电极30、第二电极40以及导体50可以是如图1(a)所示设置在不同的衬底基板上，也可以是如图1(b)所示设置在同一衬底基板上。当第一电极30、第二电极40以及导体50设置在不同的衬底基板上时，例如，可以是第一电极30、第二电极40设置在第一衬底基板10上，导体50设置在第二衬底基板20上，或者，也可以是第一电极30、第二电极40设置在第二衬底基板20上，导体50设置在第一衬底基板10上；当第一电极30、第二电极40以及导体50设置在同一衬底基板上时，例如，可以是第一电极30、第二电极40以及导体50同时设置在第一衬底基板10或同时设置在第二衬底基板20上。
至少一些实施例中，可以给第一电极30和第二电极40施加不同的电压，在二者之间形成电势差，这样第一电极30和第二电极40之间便会产生电场。 其中，电场方向与施加到第一电极30和第二电极40上电压有关，电场方向由高电压指向低电压。由于第一电极30和第二电极40位于同一个承载面上，因而第一电极30和第二电极40之间产生横向电场。
此处，第一电极30和第二电极40位于同一个承载面上，即指第一电极30和第二电极40与同一膜层接触。
至少一些实施例中，对于导体50的类型不进行限定，只要能产生磁场方向垂直于第一衬底基板10的平面(或第二衬底基板20的平面)的磁场即可。导体50例如可以是具有磁性的材料形成的图案，也可以是螺旋状线圈。
例如，导体50产生磁场的磁场方向可以是如图1(a)所示垂直于第一衬底基板10的平面，且由第一衬底基板10指向第二衬底基板20的方向，也可以是如图1(b)所示，垂直于第一衬底基板10的平面，且由第二衬底基板20指向第一衬底基板10。
液晶显示面板中通常第一衬底基板10和第二衬底基板20平行，因而磁场方向垂直于第一衬底基板10，也即磁场方向垂直于第二衬底基板20。
至少一些实施例中，导体50位于第一电极30和第二电极40之间可以是如图1(b)所示，第一电极30、第二电极40和导体50设置在同一衬底基板上，也可以是如图1(a)所示，第一电极30、第二电极40和导体50设置在不同的衬底基板上，此时只要导体50向第一电极30和第二电极40所在的衬底基板投影后，导体50的投影在第一电极30和第二电极40之间，均可以认为导体50位于第一电极30和第二电极40之间。
至少一些实施例中，本公开说明书附图仅示意出与本公开最相关的结构，其它未示意出的结构不代表在实际产品中不存在。例如，液晶显示面板除包括第一衬底基板10、第二衬底基板20和液晶层外，还包括薄膜晶体管、像素电极、公共电极以及彩色膜层等，其中，薄膜晶体管和像素电极设置在同一衬底基板上，公共电极和彩色膜层可以和薄膜晶体管、像素电极设置在同一衬底基板上，也可以设置在不同的衬底基板上。
至少一些实施例中，当第一衬底基板10和第二衬底基板20还包括其它膜层时，对于第一电极30、第二电极40以及导体50的设置位置不进行限定，可以设置在其它膜层与衬底基板之间，也可以设置在衬底基板最靠近液晶层的位置。示例的，当第一电极30和第二电极40设置在第一衬底基板10上时， 若第一衬底基板10上还设置有彩色膜层，此时第一电极30和第二电极40可以设置在第一衬底基板10和彩色膜层之间，也可以设置在彩色膜层远离第一衬底基板10的一侧。本公开实施例中，第一电极30、第二电极40以及导体50设置在第一衬底基板10或第二衬底基板20靠近液晶层的一侧，且设置在最靠近液晶层的位置。
至少一些实施例中，液晶显示面板的显示区包括多个透光区域和围绕在透光区四周的非透光区域，第一电极30、第二电极40以及导体50可以设置在液晶显示面板的透光区域，也可以设置在液晶显示面板的非透光区域。但是，当设置在透光区域时，应确保不影响液晶显示面板的正常显示，例如可以在液晶显示面板显示画面之前，利用第一电极30和第二电极40产生的电场和导体50产生的磁场使液晶层中游离态的离子被固定。
本公开实施例提供一种液晶显示面板，由于液晶显示面板包括第一电极30和第二电极40，且第一电极30和第二电极40能够产生横向电场，因而液晶层中的杂质离子会在横向电场的作用下移动，此外，液晶显示面板还包括位于第一电极30和第二电极40之间的导体50，且导体50的磁场方向垂直于第一衬底基板的平面，因而运动的杂质离子会在电场的作用下运动至导体50产生的磁场中，且杂质离子在磁场力的作用下会以一定速度向靠近第一衬底基板10或第二衬底基板20的方向运动，从而撞击到靠近液晶层的膜层上，进而杂质离子被固定在靠近液晶层的两个膜层上，这样便可以减少液晶层中游离态的离子浓度，避免FLK值偏大、FLK值漂移或残像等不良，提高了液晶显示面板的显示效果。
至少一些实施例中，导体50和第一电极30、第二电极40位于不同的衬底基板上。例如，可以是如图1(a)所示，将导体50设置在第一衬底基板10上，将第一电极30、第二电极40设置在第二衬底基板20上，也可以将导体50设置在第二衬底基板20上，将第一电极30、第二电极40设置在第一衬底基板10上。
本公开实施例中，将导体50与第一电极30、第二电极40设置在不同的衬底基板上，可以避免导体50产生的磁场和第一电极30与第二电极40产生的电场之间相互影响。
例如，如图2所示，导体50为螺旋状线圈。
需要说明的是，由于螺旋状线圈在使用时需要使螺旋状线圈中有电流通过，因而螺旋状线圈的两端需要与电流端连接，因此在设计时，位于螺旋状线圈中间的端部需穿过多个环与电流端连接。此时，螺旋状线圈相当于一个小型的电磁铁，穿过多个环的部分相当于一个小的铁芯，当给螺旋状线圈通入电流时，螺旋状线圈产生磁场，根据安培定则，磁场方向垂直于螺旋状线圈，即磁场方向垂直于第一衬底基板10或第二衬底基板20的平面。
此处，可以通过改变通入到螺旋状线圈的电流方向，来改变磁场方向。
本公开实施例中，对于螺旋状线圈的环数不进行限定，可以根据需要对螺旋状线圈的环数进行相应设置。在此基础上，可以通过调整螺旋状线圈的环数和螺旋状线圈上通过的电流大小，来调整螺旋状线圈产生的磁场大小。
本公开实施例中，由于螺旋状线圈价格便宜，生产工艺简单。此外可以通过调整螺旋状线圈的环数和螺旋状线圈上通过的电流大小，来调整螺旋状线圈产生的磁场大小，通过调整通入到螺旋状线圈的电流方向，来调整磁场方向，使用方便简单，因而本公开实施例导体50为螺旋状线圈。
例如，如图3(a)和图3(b)所示，液晶显示面板还包括设置在液晶层两侧的取向膜60。需要说明的是，附图3(a)和图3(b)中以导体50为螺旋状线圈为例进行示意。取向膜60用于使液晶按照一定的取向进行排布。
如图3(a)所示，第一电极30、第二电极40和导体50可以均设置在取向膜60靠近液晶层的一侧，也可以如图3(b)所示，均设置在取向膜60远离液晶层的一侧，其他实施例中，第一电极30和第二电极40设置在取向膜60靠近液晶层的一侧，导体50设置在取向膜60远离液晶层的一侧，或者，第一电极30和第二电极40设置在取向膜60远离液晶层的一侧，导体50设置在取向膜60靠近液晶层的一侧(未示意出)。基于上述，为了使液晶层中的杂质离子能更多地被固定在取向膜60上，如图3(b)所示，第一电极30、第二电极40和导体50均设置在取向膜60远离液晶层的一侧。
本公开实施例中，由于液晶层两侧设置有取向膜60，因而当游离态的离子在导体50产生的磁场和第一电极30、第二电极40产生的电场的作用下，以一定速度撞击到取向膜60上时，由于取向膜60上具有沟槽，因而离子便可以被牢固地固定在取向膜60上，从而可以避免离子再回到液晶层中。
例如，如图4所示，第一电极30、第二电极40和导体50设置在液晶显 示面板的非透光区域01中。液晶显示面板的显示区包括非透光区01和透光区域02，其中透光区域02用于显示。第一电极30和第二电极40和导体50均设置任意两个相邻透光区02之间。
图4以第一电极30、第二电极40和导体50设置在同一衬底基板上为例进行示意，但并不限于此。
本公开实施例中，将第一电极30、第二电极40和导体50设置在非透光区域01中，这样一方面可以避免影响液晶显示面板的正常显示；另一方面，可以避免降低光的透过率。
例如，如图4(a)、图4(b)以及图5所示，第一衬底基板10或第二衬底基板20上设置有沿列方向依次排列的多条数据线；第一电极30为奇数列数据线，第二电极40为偶数列数据线。本公开实施例中，相邻两个透光区域02之间设置有两条数据线。
本公开实施例中，当需要第一电极30和第二电极40产生电场时，给奇数列数据线和偶数列数据线输入不同的电压，这时奇数列数据线和偶数列数据线便会产生电场。此处，本领域技术人员应该明白，当利用奇数列数据线和偶数列数据线产生电场时，此时应不影响液晶显示面板的正常显示。
本公开实施例中，利用奇数列数据线充当第一电极30，利用偶数列数据线充当第二电极40，这样便无需额外设置第一电极30和第二电极40，从而可以简化液晶显示面板的制作工艺。
例如，如图4(a)、图4(b)以及图4(c)所示，液晶显示面板包括均匀分布在第一衬底基板10或第二衬底基板20上的多个导体50和多个条状第一电极30与第二电极40。这里，术语“均匀分布”可以指多个第一电极30等间距排列，和/或多个第二电极40等间距排列，和/或多个导体50等间距排列。第一电极30在衬底基板上的投影到导体50在同一衬底基板上的投影的距离等于第二电极40在衬底基板上的投影到导体50在同一衬底基板上的投影的距离。
当第一衬底基板10或第二衬底基板20包括多个导体50和多个条状第一电极30与第二电极40时，可以是如图4(a)所示，一个第一电极30和一个第二电极40之间设置一个导体50；也可以是如图4(b)所示，一个第一电极30和一个第二电极40之间设置多个导体50；当然也可以是如图4(c)所示，一 个导体50设置在多对第一电极30和第二电极40之间。
在此基础上，当导体50为螺旋状线圈时，多个导体50之间可以相互串联起来，也可以相互不连接。此外，多个第一电极30可以相互连接，也可以相互不连接，多个第二电极40可以相互连接，也可以相互不连接。当第一电极30和第二电极40为数据线时，本领域技术人员应该明白，多个第一电极30之间相互不连接，多个第二电极40之间相互不连接。
本公开实施例中，多个导体50、多个条状第一电极30和多个条状第二电极40均匀分布在第一衬底基板10或第二衬底基板20上，这样便可以使液晶层中的离子被均匀固定，从而可以确保整个液晶层中游离态的离子浓度均匀，进而确保液晶显示面板的性能均匀。
当液晶显示面板包括多个导体50，且导体50为螺旋状线圈时，若多个螺旋状线圈之间相互不连接，为了使每个螺旋状线圈都能产生磁场，则每个螺旋状线圈的两个端部都需要与电流端相连，以形成回路，这样便使得液晶显示面板的制作过程较为复杂，因而本公开实施例中，如图5所示，导体50为螺旋状线圈，多个螺旋状线圈串联在一起，这样当需要螺旋状线圈产生磁场时，只需要将多个螺旋状线圈的未连接的两个端部(如图5中a点和b点所示)与电流端相连即可，这样电流通过每个螺旋状线圈，便可以每个螺旋状线圈都能产生磁场，且简化了液晶显示面板的制作工艺。
本公开实施例还提供一种液晶显示装置，包括上述的液晶显示面板。
至少一些实施例中，液晶显示装置还包括控制电路；控制电路包括第一电压输出端和第二电压输出端，第一电压输出端与第一电极30电连接，第二电压输出端与第二电极40电连接；其中，第一电压输出端的电压和第二电压输出端的电压之间形成电势差。
本公开实施例提供的液晶显示装置可以是显示不论运动(例如，视频)还是固定(例如，静止图像)的且不论文字还是图画的图像的任何装置。更明确地说，预期所述实施例可实施在多种电子装置中或与多种电子装置关联，所述多种电子装置例如(包括但不限于)移动电话、无线装置、个人数据助理(PDA)、手持式或便携式计算机、GPS接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如，里程表显示器等)、导航仪、座舱控制器 和/或显示器、相机视图的显示器(例如，车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构(例如，对于一件珠宝的图像的显示器)等。
本公开实施例中，由于第一电压输出端与第一电极30电连接，因而第一电压输出端可以为第一电极30提供电压，第二电压输出端与第二电极40电连接，因而第二电压输出端可以为第二电极40提供电压。在此基础上，由于第一电压输出端的电压和第二电压输出端的电压之间形成电势差，因而第一电极30和第二电极40上电压不同，因此第一电极30和第二电极40之间会产生电场，而液晶层中游离态的杂质离子会在电场的作用下移动。由于液晶显示面板还包括位于第一电极30和第二电极40之间的导体50，且导体50的磁场方向垂直于第一衬底基板10的平面，因而运动的杂质离子会在电场的作用下运动至导体50产生的磁场中，且杂质离子在磁场力的作用下会以一定速度向靠近第一衬底基板10或第二衬底基板20的方向运动，从而撞击到靠近液晶层的膜层上，进而杂质离子被固定在靠近液晶层的两个膜层上，这样便可以减少液晶层中游离态的离子浓度。
至少一些实施例中，控制电路还包括一对电流端；导体50为螺旋状线圈，一对电流端分别与螺旋状线圈的两端电连接。
例如，一对电流端分别与螺旋状线圈的两端电连接，以形成回路。一对电流端中一个用于将电流输入至螺旋状线圈，另一个用于使螺旋状线圈中的电流流入该电流端，这样便可以形成回路。
本公开实施例中，由于控制电路还包括一对电流端，且该一对电流端分别与螺旋状线圈的两端电连接，因而螺旋状线圈中会有电流流过，因此螺旋状线圈会产生垂直于第一衬底基板10或第二衬底基板20的磁场。
本公开实施例还提供一种上述的液晶显示装置的控制方法，包括：在液晶显示装置显示画面之前，(或者可理解为，在显示一帧画面之后且在显示下一帧画面之前)向第一电极30和第二电极40分别输入大小不同的电压信号以在第一电极和第二电极之间形成电势差。
此处，向第一电极30和第二电极40分别输入大小不同的电压信号，因而第一电极30和第二电极40之间会产生电场，且电场线方向由高电压指向低电压。
本公开实施例中，由于在液晶显示装置显示画面之前，向第一电极30和第二电极40输入电压信号，因而这样便不会影响液晶显示装置的正常显示。在此基础上，第一电极30和第二电极40之间会产生电场，而液晶层中游离态的杂质离子会在电场的作用下移动，由于液晶显示面板还包括位于第一电极30和第二电极40之间的导体50，且导体50的磁场方向垂直于第一衬底基板10的平面，因而运动的杂质离子会在电场的作用下运动至导体50产生的磁场中，且杂质离子在磁场力的作用下会以一定速度向靠近第一衬底基板10或第二衬底基板20的方向运动，从而撞击到靠近液晶层的膜层上，进而杂质离子被固定在靠近液晶层的两个膜层上，这样便可以减少液晶层中游离态的离子浓度。
至少一些实施例中，导体50为螺旋状线圈，控制方法还包括：向螺旋状线圈输入电流信号。
其中，对于螺旋状线圈中流过的电流大小和方向不进行限定，可以根据需要进行调整。此处，螺旋状线圈产生磁场的磁场方向与螺旋状线圈中流过的电流方向有关。
本公开实施例中，当向螺旋状线圈输入电流信号时，螺旋状线圈便会产生磁场方向垂直于第一衬底基板10的平面或第二衬底基板20的平面的磁场。
上述实施例的液晶显示面板、液晶显示装置及其控制方法中，由于液晶显示面板包括第一电极和第二电极，且第一电极和第二电极能够产生横向电场，因而液晶层中游离态的杂质离子会在横向电场的作用下移动，此外，液晶显示面板还包括位于第一电极和第二电极之间的导体，且导体的磁场方向垂直于第一衬底基板，因而运动的杂质离子会在电场的作用下运动至导体产生的磁场中，且杂质离子在磁场力的作用下会以一定速度向靠近第一衬底基板或第二衬底基板的方向运动，从而撞击到靠近液晶层的膜层上，进而杂质离子被固定在靠近液晶层的两个膜层上，这样便可以减少液晶层中游离态的离子浓度，避免FLK值偏大、FLK值漂移或残像等不良，提高了液晶显示面板的显示效果。
