具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明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发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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，都属于本发明保护的范围。
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。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“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。“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。
本公开的发明人在研究中注意到，普通的液晶显示装置的对比度较低。例如，普通的液晶显示装置(例如，具有单个液晶盒的基于高级超维场转换技术的液晶显示装置)通常存在暗态漏光问题，且该因素会使得液晶显示装置的显示画面的对比度较低。需要说明的是，普通的液晶显示装置的对比度较低还可能与其它因素有关，在此不再赘述。本公开的发明人在研究中注意到，可以采用具有双液晶盒的液晶显示装置来提升显示画面的对比度，下面结合图1A进行示例性说明。
图1A示出了一种液晶显示装置500的截面示意图。如图1A所示，该液晶显示装置500包括顺次设置的背光单元503、控光面板502和显示面板501。图1B示出了图1A所示的液晶显示装置500的控光面板502和显示面板501的平面示意图。图1C示出了图1A所示的液晶显示装置500的控光面板502(控光面板502的阵列基板)的平面示意图。例如，控光面板502被配置为调节背光单元503发射的且入射至显示面板501上的光线的强度。例如，从控光面板502出射的光线为白光，也即，控光面板502不具有色彩调节功能(例如，仅进行灰度显示)。
如图1B所示，显示面板501包括多根沿第一方向D1延伸的第一信号线 541以及多根沿第二方向D2延伸的第二信号线542；多根第一信号线541和多根第二信号线542相交界定多个阵列排布的显示子像素单元，多个显示子像素单元形成阵列排布的多个显示像素单元530；每个显示像素单元530包括第一显示子像素单元531、第二显示子像素单元532和第三显示子像素单元533；第一显示子像素单元531、第二显示子像素单元532和第三显示子像素单元533例如分别为红色显示子像素单元、绿色显示子像素单元和蓝色显示子像素单元。例如，第一方向D1垂直于第二方向D2。例如，第一信号线541为显示面板501的栅线，第二信号线542为显示面板501的数据线。
如图1B和图1C所示，控光面板502(控光面板502的阵列基板551)包括分别沿第一方向D1延伸的多根栅线510以及分别沿与第一方向D1相交的第二方向D2的延伸的多根数据线521；多根栅线510和多根数据线521相交界定多个控光像素单元523。例如，控光面板502还包括分别沿与第二方向D2的延伸的多根公共电极线522。例如，控光面板502包括多个阵列布置的控光单元，阵列基板551的多个控光像素单元523分别设置在对应的控光单元中。
例如，该控光面板502可以基于数据线521接收的数据信号来调节控光面板的各个控光单元的透射率，因此，控光面板502的控光单元可用于控制入射至对应于该控光单元的显示面板501的显示子像素单元上的光线的强度，由此控光面板502可用于向显示面板501提供调节后的背光。例如，通过在显示装置500中设置控光面板502，可以使得对应于液晶显示装置的显示画面的亮度较低(例如，亮度为零)的区域的控光单元的透射率较低(例如，透射率等于或接近于零)，此种情况下，采用具有双液晶盒的液晶显示装置(也即，具有控光面板的显示装置)可以提升显示画面的对比度。
例如，第一信号线541的宽度大于栅线510的宽度。例如，第一显示子像素单元531、第二显示子像素单元532和第三显示子像素单元533在第一方向D1上的尺寸彼此相同，例如，第一显示子像素单元531、第二显示子像素单元532和第三显示子像素单元533在第二方向D2上的尺寸彼此相同。
如图1B和图1C所示，控光面板502的每根栅线510实现为折线走线；每根栅线510包括多个第一走线部分511和多个第二走线部分512，多个第一走线部分511和多个第二走线部分512交替布置，且相邻的第一走线部分511和第二走线部分512彼此相连。如图1B所示，第一走线部分511(或/和第二 走线部分512)与第一方向D1的夹角α(锐角)约为50-70度，以降低液晶显示装置500的摩尔纹问题。例如，第一走线部分511和第二走线部分512均为直线走线部分(直线走线)。在一些示例中，控光面板502的至少部分栅线510还实现为直线。
图1D示出了图1A所示的控光面板502的控光像素单元523的平面示意图。如图1D所示，控光像素单元523在第一方向D1上的尺寸为Sz1，控光像素单元523在第二方向D2上的尺寸为Sz2。如图1B-图1D所示，控光像素单元523在第一方向D1上的尺寸Sz1等于显示像素单元530在第一方向D1上的尺寸的两倍，控光像素单元523在第二方向D2上的尺寸Sz2等于显示像素单元530在第二方向D2上的尺寸的四倍。
图1E示出了图1A所示的液晶显示装置500另一种截面示意图。例如，如图1E所示，显示面板501还包括第一阵列基板501a、第一液晶层501b和第一对置基板501c；控光面板502还包括第二阵列基板502a、第二液晶层502b和第二对置基板502c；液晶显示装置500还包括第一柔性电路板501d、用于显示面板501的第一电路板501e、第二柔性电路板502d以及用于控光面板502的第二电路板502e；第一柔性电路板501d的第一端与显示面板501的第一阵列基板501a绑定，第一柔性电路板501d的第二端与第一电路板501e绑定；第二柔性电路板502d的第一端与控光面板502的第二阵列基板502a绑定，第二柔性电路板502d的第二端与第二电路板502e绑定。
本公开的发明人在研究中注意到，用于显示面板501的第一电路板501e以及用于控光面板502的第二电路板502e在显示面板501和控光面板502的叠置方向(例如，与第一方向D1和第二方向D2垂直的第三方向D3)上至少部分重叠，以及第一柔性电路板501d和第二柔性电路板502d在显示面板501和控光面板502的叠置方向(例如，与第一方向D1和第二方向D2垂直的第三方向D3)上至少部分重叠；此种情况下，用于显示面板501的第一电路板501e以及用于控光面板502的第二电路板502e之间可能存在相互摩擦或/和第一柔性电路板501d和第二柔性电路板502d之间可能存在相互摩擦；此种情况下，可能导致因摩擦导致的显示不良。例如，上述显示不良是因为第一柔性电路板501d、第一电路板501e、第二柔性电路板502d和第二电路板502e至少一个的走线(或元件)磨损或温度升高(例如，因为摩擦产生的热量集中)导致。
本公开的至少一个实施例提供了一种显示模组和显示装置。例如，该显示模组包括显示面板、控光面板、用于显示面板的至少一个第一电路板以及用于控光面板的至少一个第二电路板。显示面板和控光面板层叠设置；显示面板位于控光面板的出光侧；显示面板的出光面位于第一面上；至少一个第一电路板在第一面上的正投影的任一个的至少部分与至少一个第二电路板在第一面上的正投影在垂直于第一面的方向上不重叠。
例如，通过使得用于显示面板的至少一个第一电路板的至少部分以及用于控光面板的至少一个第二电路板在垂直于第一面的方向上不重叠，可以降低用于显示面板的至少一个第一电路板以及用于控光面板的至少一个第二电路板之间摩擦的可能性以及降低显示不良(例如，运输过程导致的显示不良)的可能性。
例如，至少一个第一电路板在第一面上的正投影的任一个与至少一个第二电路板在第一面上的正投影在垂直于第一面的方向上不重叠。
需要说明的是，尽管附图5等将控光面板20示意为液晶面板，但本公开的至少一个实施例的控光面板20不限于实现为液晶面板。在一些示例中，控光面板20还可以实现为自发光面板，此种情况下，本公开的至少一个实施例提供了一种显示模组可以不包括背光单元。例如，自发光面板可以实现为无机发光面板或有机发光面板。例如，无机发光面板可以包括多个无机发光二级管，多个无机发光二级管例如阵列排布。例如，无机发光二级管可以实现为迷你发光二级管迷你发光二极管(Mini LED)或微发光二极管(Micro LED)或其他适用的发光二级管。
下面通过几个示例或实施例对根据本公开实施例提供的显示模组和显示装置进行非限制性的说明，如下面所描述的，在不相互抵触的情况下这些具体示例或实施例中不同特征可以相互组合，从而得到新的示例或实施例，这些新的示例或实施例也都属于本公开保护的范围。
图2是本公开的至少一个实施例提供的显示模组01的示意图；图3是本公开的至少一个实施例提供的显示模组01的平面示意图(正视图)；图4是图3所示的显示模组01的背视图。
如图2-图4所示，该显示模组01包括：显示面板10、背光单元30、控光面板20、用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210。
如图2所示，显示面板10、控光面板20和背光单元30层叠设置(例如，在第三方向D3上层叠设置)；显示面板10位于控光面板20的出光侧；背光单元30位于控光面板20远离显示面板10的一侧。
如图3和图4所示，显示面板10的出光面(也即，显示面板10的远离背光单元30的面)位于第一面上，至少一个第一电路板110在第一面上的正投影的任一个的至少部分区域与至少一个第二电路板210(例如，所有的第二电路板210)在第一面上的正投影在垂直于第一面的方向上不重叠。
例如，至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210(例如，所有的第二电路板210)在第一面上的正投影在垂直于第一面的方向上不重叠。
例如，至少一个第一电路板110和至少一个第二电路板210均位于控光面板20远离显示面板10的一侧。例如，至少一个第一电路板110和至少一个第二电路板210均位于背光单元30远离显示面板10的一侧。
例如，通过使得至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210在第一面上的正投影在垂直于第一面的方向上不重叠，可以降低用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210之间摩擦的可能性以及降低因摩擦导致的显示不良的可能性。
需要说明的是，尽管图3所示的显示面板10和控光面板20直接接触，控光面板20和背光单元30直接接触，但本公开的至少一个实施例不限于此。例如，显示面板10和控光面板20在第三方向D3上间隔设置和/或控光面板20和背光单元30在第三方向D3上间隔设置。
需要说明的是，尽管图3所示的显示模组01的正视图还示出了第一电路板110和第二电路板210，但是，在包括该显示模组01的显示装置的实际产品中，用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210位于背光单元30的远离控光面板20的一侧；本领域技术人员可以理解，在包括该显示模组01的显示装置的实际产品中，图3所示的虚线下方的元件(或元件的部分)均位于背光单元30的远离控光面板20的一侧；此种情况下，图3所示的显示模组01的正视图可以与图24所示的显示模组01的正视图相同或相似。
例如，第一电路板110和第二电路板210均为印制电路板。在第一个示 例中，第一电路板110和第二电路板210分别与第一时序控制器印制电路板(图中未示出)和第二时序控制器印制电路板(图中未示出)电连接，以分别从第一时序控制器印制电路板和第二时序控制器印制电路板接收驱动信号，并分别向第一柔性电路板120和第二柔性电路板220提供驱动信号。在第二个示例中，第一电路板110和第二电路板210分别为第一时序控制器印制电路板和第二时序控制器印制电路板接，以分别向第一柔性电路板120和第二柔性电路板220提供驱动信号。
例如，包括该显示模组01的显示装置包括第一时序控制器印制电路板和第二时序控制器印制电路板。例如，第一时序控制器印制电路板和第二时序控制器印制电路板的至少一个(例如，全部)包括时序控制器。例如，第一时序控制器印制电路板和第二时序控制器印制电路板的至少一个(例如，全部)还可以包括伽马电路、电源管理集成电路，公共电极电压电路的至少一个。例如，上述驱动信号包括数字工作电压(DVDD)。例如，上述驱动信号还可以包括栅开启电压和栅关闭电压。
例如，如图3和图4所示，至少一个第一电路板110和至少一个第二电路板210分别在第一方向D1上延伸；至少一个第一电路板110在第一面上的正投影和至少一个第二电路板210在第一面上的正投影在与第一方向D1交叉的第二方向D2上至少部分重叠。例如，第一方向D1、第二方向D2和第三方向D3彼此交叉(例如，垂直)。
例如，“至少一个第一电路板110在第一面上的正投影和至少一个第二电路板210在第一面上的正投影在第二方向D2上至少部分重叠”是指：沿着第二方向D2观察(例如，从图4的上侧向下侧观察)至少一个第一电路板110在第一面上的正投影和至少一个第二电路板210在第一面上的正投影，第二电路板210在第一面上的正投影至少部分遮挡对应的第一电路板110在第一面上的正投影。例如，本公开的至少一个实施例中描述的“在第一方向上至少部分重叠”具有相同或相似的含义，不再赘述。
例如，如图3和图4所示，至少一个第一电路板110在第一面上的正投影与至少一个第二电路板210在第一面上的正投影在第二方向D2上间隔设置，由此使得至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210在第一面上的正投影在垂直于第一面的方向上不重叠。
图5是图4所示的显示模组01的沿B-B’线的剖面图；图6是图4所示 的显示模组01的沿C-C’线的剖面图。
例如，如图5所示，显示面板10还包括第一阵列基板151、第一液晶层153和第一对置基板152；控光面板20包括第二阵列基板251、第二液晶层253和第二对置基板252。例如，如图5所示，背光单元30、第二阵列基板251、第二液晶层253、第二对置基板252、第一阵列基板151、第一液晶层153和第一对置基板152在第三方向D3上顺次设置。
例如，如图3-图5所示，显示模组01还包括：至少一个第一柔性电路板120和至少一个第二柔性电路板220；至少一个第一柔性电路板120的第一端与显示面板10绑定(显示面板10的第一阵列基板151)，至少一个第一柔性电路板120的第二端与至少一个第一电路板110绑定，由此使得显示面板10可操作的连接到至少一个第一电路板110；至少一个第二柔性电路板220的第一端与控光面板20(控光面板20的第二阵列基板251)绑定，至少一个第二柔性电路板220的第二端与至少一个第二电路板210绑定，由此控光面板20可操作的连接到至少一个第二电路板210。
例如，如图4所示，显示模组01包括在第一方向D1上对置的第一侧S1和第二侧S2以及在第二方向D2上对置的第三侧S3和第四侧S4。例如，如图3所示，至少一个第一柔性电路板120与显示面板10绑定位置以及至少一个第二柔性电路板220与控光面板20的绑定位置均位于显示模组01的同一侧(例如，第四侧S4)。
例如，如图4所示，在包括该显示模组01的显示装置的实际产品中，至少一个第一柔性电路板120和至少一个第二柔性电路板220被弯折，以使得用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210位于背光单元30的远离控光面板20的一侧。例如，如图4所示，在包括该显示模组01的显示装置的实际产品中，至少一个第一柔性电路板120和至少一个第二柔性电路板220的每个的部分也位于背光单元30的远离控光面板20的一侧。例如，如图4所示，至少一个第一电路板110以及至少一个第二电路板210与显示模组的显示区域011至少部分重叠。
例如，如图3所示，至少一个第一柔性电路板120的长度(例如，物理长度)小于至少一个第二柔性电路板220的长度(例如，物理长度)。例如，如图3所示，至少一个第二柔性电路板220的长度与至少一个第一柔性电路板120的长度的差值大于等于至少一个第一电路板110在第二方向D2的宽 度；此种情况下，在至少一个第一柔性电路板120和至少一个第二柔性电路板220被弯折之前，至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210在第一面上的正投影在垂直于第一面的方向上不重叠，由此可以进一步地降低用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210之间摩擦的可能性以及因摩擦导致的显示不良的可能性。
需要说明的是，尽管在图3所示的显示模组01中，至少一个第二柔性电路板220的长度与至少一个第一柔性电路板120的长度的差值大于等于至少一个第一电路板110在第二方向D2的宽度，但本公开的至少一个实施例不限于此。例如，至少一个第二柔性电路板220的长度与至少一个第一柔性电路板120的长度的差值还可以小于至少一个第一电路板110在第二方向D2的宽度，甚至至少一个第一柔性电路板120的长度(例如，物理长度)大于至少一个第二柔性电路板220的长度(例如，物理长度)，只要在最终产品中，至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210在第一面上的正投影在垂直于第一面的方向上不重叠(例如，至少一个第一电路板110在第一面上的正投影与至少一个第二电路板210在第一面上的正投影在第二方向D2上间隔设置)即可。
例如，如图4所示，至少一个第二柔性电路板220的位于背光单元30的远离控光面板20的一侧的部分的长度(例如，在第二方向D2上的长度)大于等于至少一个第一柔性电路板120的位于背光单元30的远离控光面板20的一侧的部分的长度(例如，在第二方向D2上的长度)；此种情况下，至少一个第一电路板110在第一面上的正投影的任一个与至少一个第二电路板210在第一面上的正投影在垂直于第一面的方向上不重叠。
例如，图3所示的显示模组01包括的显示面板10和控光面板20可以采用图1B所示的显示面板10和控光面板20，但本公开的至少一个实施例不限于此。例如，图3所示的显示模组01包括控光面板20可以采用与图1B所示的控光面板20相似的控光面板20；例如，在与图1B所示的控光面板20相似的控光面板20中，控光面板20的数据线为弯折线。
例如，显示面板10包括阵列排布的多个显示子像素单元171(参见下面的图12)，控光面板20包括阵列排布的多个控光像素单元271(参见下面的图13)；多个显示子像素单元171形成阵列排布的多个显示像素单元，多个显 示像素单元的每个例如包括三个显示子像素单元171，上述显示子像素单元171例如分别为红色显示子像素单元、绿色显示子像素单元和蓝色显示子像素单元。
例如，控光像素单元271在第一方向D1上的尺寸S1等于显示像素单元在第一方向D1上的尺寸的两倍，控光像素单元271在第二方向D2上的尺寸S2等于显示像素单元在第二方向D2上的尺寸的四倍。例如，显示面板10的分辨率等于控光面板20分辨率的两倍；此种情况下，至少一个第二柔性电路板220的数目例如可以等于至少一个第一柔性电路板120的数目的两倍。例如，显示面板10的分辨率和控光面板20分辨率分别等于8K和4K；又例如，显示面板10的分辨率和控光面板20分辨率分别等于4K和2K。
图7是图3所示的显示模组01的沿A-A’线的剖面图。例如，如图3和图7所示，至少一个第一柔性电路板120的任一个在第一面上的正投影与至少一个第二柔性电路板220(例如，所有的第二柔性电路板220)在第一面上的正投影在第一方向D1上间隔设置。
例如，通过使得至少一个第一柔性电路板120的任一个在第一面上的正投影与至少一个第二柔性电路板220在第一面上的正投影在第一方向D1上间隔设置，由此可以降低至少一个第一柔性电路板120以及至少一个第二柔性电路板220之间摩擦的可能性以及因摩擦导致的显示不良的可能性。
例如，如图3和图7所示，至少一个第一柔性电路板120包括在第一方向D1上并列布置的多个第一柔性电路板120；至少一个第二柔性电路板220包括在第一方向D1上并列布置的多个第二柔性电路板220。
例如，显示面板10包括多根第一信号线131，控光面板20包括多根第二信号线231。例如，多根第一信号线131和多根第二信号线231的每根整体沿第二方向D2延伸。需要说明的是，多根第一信号线131和多根第二信号线231的每根整体沿第二方向D2延伸仅限定了多根第一信号线131和多根第二信号线231的延伸方向，而并不表示多根第一信号线131和多根第二信号线231的每根包括的走线处处平行于第二方向D2。例如，多根第一信号线131的每根平行于第二方向D2；多根第二信号线231的每根包括弯折线。
例如，多个第一柔性电路板120包括的与第一信号线131电连接的走线的总体数目等于多根第一信号线131的数目；多个第二柔性电路板220包括的与第二信号线231电连接的走线的总体数目等于第二信号线231的数目。
例如，多根第一信号线131的数目大于多根第二信号线231的数目；对应地，多个第一柔性电路板120的数目大于等于多个第二柔性电路板220的数目和/或多个第一柔性电路板120的每个包括的与第一信号线131电连接的走线的数目大于多个第二柔性电路板220的每个包括的与第二信号线231电连接的走线的数目。
例如，在采用图1B所示的显示面板和控光面板的情况下，多根第一信号线131的数目实质上等于多根第二信号线231的数目的6倍；对应地，多个第一柔性电路板120包括的与第一信号线131电连接的走线的总体数目实质上等于多个第二柔性电路板220包括的与第二信号线231电连接的走线的总体数目的6倍。
例如，第一柔性电路板120包括的走线不限于与第一信号线131电连接的走线，第一柔性电路板120包括的走线还可以包括下面的第三走线或者其它适用的走线。例如，第二柔性电路板220包括的走线不限于与第二信号线231电连接的走线，第二柔性电路板220包括的走线还可以包括下面的第四走线或者其它适用的走线。
例如，如图3和图7所示，在第一方向D1上相邻的两个第二柔性电路板220之间设置至少两个第一柔性电路板120。
需要说明的是，为清楚起见，图3和图7所示的显示模组01中，多个第一柔性电路板120的数目和多个第二柔性电路板220的数目分别等于6和3，但本公开的至少一个实施例不限于此。例如，多个第一柔性电路板120的数目和多个第二柔性电路板220的数目可以根据显示模组01的尺寸进行设定。例如，对于65寸的显示模组01，显示面板10的分辨率和控光面板20分辨率可以分别等于4K和2K，多个第一柔性电路板120的数目和多个第二柔性电路板220的数目分别等于12和6。例如，对于86寸的显示模组01，显示面板10的分辨率和控光面板20分辨率可以分别等于4K和2K，多个第一柔性电路板120的数目和多个第二柔性电路板220的数目分别等于48(单侧24个，双侧绑定)和24(单侧12个，双侧绑定)。
在一些示例中(例如，显示模组01仅具有显示功能，但不具有触控功能)，如图3和图7所示，多个第一柔性电路板120的数目等于多个第二柔性电路板220的数目两倍，但本公开的至少一个实施例不限于此。例如，在显示模组01还具有触控功能的情况下，多个第一柔性电路板120的数目可以等于多 个第二柔性电路板220的数目两倍、四倍、六倍或者其它适用的数目。
例如，如图3和图4所示，与至少一个第一电路板110的每个绑定的第一柔性电路板120数目(例如，三个)等于与至少一个第二电路板210的每个绑定的第二柔性电路板220数目，此种情况下，至少一个第一电路板110的数目大于至少一个第二电路板210的数目；至少一个第一电路板110的每个在第一方向D1上的长度小于至少一个第二电路板210的每个在第一方向D1上的长度。
例如，如图3和图4所示，至少一个第一电路板110包括在第一方向D1上并列布置的多个第一电路板110；至少一个第二电路板210包括在第一方向D1上并列布置的多个第二电路板210。例如，如图3和图4所示，多个第一电路板110的数目等于多个第二电路板210的数目的二倍。
例如，如图3和图4所示，与多个第一电路板110的每个绑定的第一柔性电路板120数目(例如，三个)等于与多个第二电路板210的每个绑定的第二柔性电路板220数目。
例如，如图3和图4所示，在第一方向D1上，多个第二柔性电路板220的至少一个设置在相邻的两个第一电路板110，由此可以避免上述多个第二柔性电路板220的至少一个与第一电路板110之间的摩擦，由此可以进一步地降低因摩擦导致的显示不良(例如，运输过程导致的显示不良)的可能性。需要说明的是，相邻的两个第一电路板110是指上述两个相邻的两个第一电路板110之间未设置其它第一电路板110，但是可以设置其它元件(例如，第二柔性电路板220)。

例如，多个第一柔性电路板120的每个包括多个第一引脚(pin)；多个第二柔性电路板220的每个包括多个第二引脚。例如，多个第一引脚的数目可以与多个第二引脚的数目相等；此种情况下，第二柔性电路板220中的部分 第二引脚未与第二柔性电路板220包括的走线电连接，对应地，在实际应用中，上述部分第二引脚未被使用(例如，悬接或接地)。
例如，柔性电路板在第一方向D1上的宽度等于48毫米的情况下，柔性电路板具有960个引脚。例如，柔性电路板在第一方向D1上的宽度等于70毫米的情况下，柔性电路板具有1680个引脚。
例如，每根第一信号线131与位于同一列的显示子像素单元171电连接，每根第二信号线231与位于同一列的控光像素单元271的电连接。例如，多根第一走线121的数目实质上等于(例如，等于)多根第二走线221的数目的三倍。例如，对于前述65寸的显示模组01，多个第一柔性电路板120的每个包括多根第一走线121的数目为960根，多个第二柔性电路板220的每个包括多根第二走线221的数目为320根。例如，对于前述86寸的显示模组01，多个第一柔性电路板120的每个包括多根第一走线121的数目为1440根，多个第二柔性电路板220的每个包括多根第二走线221的数目为480根。

例如，多个第二柔性电路板220的每个包括的多根第二走线221的每根可以包括在第二方向D2上并列布置的两根第二子走线；至少部分位于第二连接线232和第二芯片223之间的第二子走线的两端分别与第二连接线232和第二芯片223的数据信号输出端电连接；至少部分位于第二电路板210和第二芯片223之间的第二子走线的两端分别与第二电路板210和第二芯片223的驱动信号输入端电连接。
需要说明的是，为清楚起见，图11所示的控光面板20的第二信号线231为直线，但本公开的至少一个实施例不限于此。例如，如图13所示，控光面板20的第二信号线231可以为弯折线。
需要说明的是，图12所示的显示面板10的示意图用于示出第一连接线132、第一防静电电路161、第三连接线162、第一信号线131和显示子像素单元171之间的连接关系，图13所示的控光面板20的示意图用于示出第二连接线232、第二防静电电路261、第四连接线262、第二信号线231和控光像素单元271之间的连接关系，本领域技术人员可以理解，图12和图13并非按照比例绘制，且各个元件的具体形状可以根据实际应用需求进行设定。
图14是图3所示的显示模组01的显示面板10的多根第一连接线132的部分的示意图；图15是图3所示的显示模组01的显示面板10的多根第一连接线132的部分的另一个示意图；图16是图3所示的显示模组01的控光面板20的多根第二连接线232的部分的示意图。

需要说明的是，线部整体上沿某一方向延伸不限于该线部平行于该方向。例如，如图14所示，第一线部132a、第三线部132c、第四线部232a和第六线部232c可以为沿第二方向D2延伸的蛇形走线。
例如，如图12-图16所示，多根第一连接线132的第二线部132b在第一方向D1的长度以第一变化率变化；多根第二连接线232的第五线部232b在第一方向D1的长度以第二变化率变化；第一变化率小于第二变化率。例如，第一变化率是指相邻的两个第二线部132b在第一方向D1的长度的差值；第二变化率是指相邻的两个第五线部232b在第一方向D1的长度的差值。
在一些示例中，上述第一变化率和第二变化率均为固定数值。在另一些示例中，上述第一变化率和第二变化率的至少一个数值不是固定数值。在再一些示例中，上述第一变化率(或第二变化率)在指定的范围内为固定数值，但在不同的范围内，上述第一变化率(或第二变化率)的取值不同。例如，多根第一连接线的第一范围(例如，多根第一连接线中从左至右第1-10根)的第二线部132b在第一方向D1的长度的变化率不等于多根第一连接线的第二范围(例如，多根第一连接线中从左至右第11-20根)的第二线部132b在第一方向D1的长度的变化率，但多根第一连接线的第一范围的第二线部132b在第一方向D1的长度的变化率以及多根第一连接线的第二范围的第二线部132b在第一方向D1的长度的变化率均小于第二变化率。
例如，多根第一连接线的至少部分根第一连接线的第二线部在第一方向的长度以第一变化率变化；多根第二连接线的至少部分根第二连接线的第五线部在第一方向的长度以第二变化率变化；第一变化率小于第二变化率。
例如，如图15所示，相邻的第一线部132a之间的间距等于a1，相邻的第三线部132c之间的间距等于b1；在第一方向D1上位于中间的第二线部132b的左侧或右侧的第N个第二线部132b在第一方向D1上的长度L1(N)满足以下的表达式：L1(N)＝e1×(a1-b1)N。例如，e1可以是位于0.1-10之内的自然数。例如，e1可以等于1。
例如，如图16所示，相邻的第四线部232a之间的间距等于a2，相邻的第六线部232c之间的间距等于b2；在第一方向D1上位于中间的第五线部232b的左侧或右侧的第M个第五线部232b在第一方向D1上的长度L2(M)满足以下的表达式：L2(M)＝e2×(a2-b2)M。例如，e2可以是位于0.1-10之内的自然数。例如，e2可以等于1。
例如，上述M为小于等于M1的正整数，上述N为小于等于N1的正整数；M1小于N1。
例如，相邻的第一线部132a之间的间距等于a1小于相邻的第四线部232a之间的间距等于a2；相邻的第三线部132c之间的间距等于b1等于相邻的第六线部232c之间的间距等于b2，此种情况下，第一变化率小于第二变化率。需要说明的是，相邻的第三线部132c之间的间距等于b1不限于等于相邻的第六线部232c之间的间距等于b2，在一些示例中，相邻的第三线部132c之间的间距等于b1还可以略小于相邻的第六线部232c之间的间距等于b2，此种情况下，第一变化率也可以小于第二变化率。

例如，如图23A所示，第一导电结构181的两端分别与第一对置基板152和第一阵列基板151直接接触，第二导电结构281的两端分别与第二阵列基板和第二屏蔽层直接接触。
例如，如图3和图23A所示，显示模组01的中心到第一导电结构181在第一面上的正投影的靠近显示模组01的中心的边的距离不同于显示模组01的中心到第二导电结构281在第一面上的正投影的靠近显示模组01的中心的边的距离。
例如，如图3和图23A所示，显示模组01的中心到第一导电结构181在第一面上的正投影的靠近显示模组01的中心的边的距离大于显示模组01的中心到第二导电结构281在第一面上的正投影的靠近显示模组01的中心的边的距离，由此使得显示面板10的第一焊盘区bd1在第二方向D2上的宽度小于控光面板20的第二焊盘区bd2在第二方向D2上的宽度；此种情况下，第一柔性电路与显示面板10的绑定位置120a以及第二柔性电路与控光面板20的绑定位置220a在第二方向D2上至少部分错开(参见图23B)，由此可以进一步地降低显示模组01在工作过程中的产生的热量集中的可能性以及因热量集中导致的显示不良的可能性。
需要说明的是，尽管图3示出的显示模组01的用于显示面板10的至少一个第一电路板110的任一个以及用于控光面板20的至少一个第二电路板210(例如，全部的第二电路板210)在垂直于第一面的方向上不重叠，并且至少一个第一柔性电路板120在第一面上的正投影的任一个与至少一个第二柔性电路板220(例如，全部的第二柔性电路板220)在第一面上的正投影在垂直于第一面的方向上不重叠，但本公开的至少一个实施例不限于此。
在第一个示例中，用于显示面板10的至少一个第一电路板110的任一个 以及用于控光面板20的至少一个第二电路板210(例如，全部的第二电路板210)在垂直于第一面的方向上不重叠，但是至少一个第一柔性电路板120在第一面上的正投影的与至少一个第二柔性电路板220在第一面上的正投影在垂直于第一面的方向上至少部分重叠。
在第二个示例中，用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210在垂直于第一面的方向上至少部分重叠，但是至少一个第一柔性电路板120的任一个在第一面上的正投影的任一个与至少一个第二柔性电路板220(例如，全部的第二柔性电路板220)在第一面上的正投影在垂直于第一面的方向上不重叠。
对于上述第一个示例和第二个示例的显示模组01，也可以在一定程度上降低摩擦导致的显示不良的可能性。

图24是本公开的至少一个实施例提供的另一种显示模组的正视图。例如，如图24所示，该显示模组包括：显示面板10、背光单元30、控光面板20、用于显示面板10的至少一个第一电路板110(图24未示出)、用于控光面板20的至少一个第二电路板210(图24未示出)、至少一个第一柔性电路板120以及至少一个第二柔性电路板220。例如，显示面板10、控光面板20和背光 单元30层叠设置；显示面板10位于控光面板20的出光侧；背光单元30位于控光面板20远离显示面板10的一侧；至少一个第一柔性电路板120的第一端与显示面板10绑定，至少一个第一柔性电路板120的第二端与至少一个第一电路板110绑定；至少一个第二柔性电路板220的第一端与控光面板20绑定，至少一个第二柔性电路板220的第二端与至少一个第二电路板210绑定；显示面板10的出光面位于第一面上；至少一个第一柔性电路板120在第一面上的正投影的任一个与至少一个第二柔性电路板220在第一面上的正投影在垂直于第一面的方向上不重叠。
例如，通过使得至少一个第一柔性电路板120在第一面上的正投影的任一个与至少一个第二柔性电路板220在第一面上的正投影在垂直于第一面的方向上不重叠，可以降低用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210之间摩擦的可能性以及因摩擦导致的显示不良的可能性。
例如，在本公开的至少一个实施例还提供了另一种显示模组01中，用于显示面板10的至少一个第一电路板110的任一个以及用于控光面板20的至少一个第二电路板210(例如，全部的第二电路板210)在垂直于第一面的方向上不重叠，此种情况下，上述另一种显示模组01与上述第二个示例所述的显示模组01相同或相似，在此不再赘述。
又例如，用于显示面板10的至少一个第一电路板110以及用于控光面板20的至少一个第二电路板210在垂直于第一面的方向上至少部分重叠，此种情况下，上述另一种显示模组01与图3-图23B所示的显示模组01相同或相似，在此不再赘述。
例如，至少一个第一电路板110和至少一个第二电路板210均位于控光面板20远离显示面板10的一侧。例如，至少一个第一电路板110和至少一个第二电路板210均位于背光单元30远离显示面板10的一侧。
本公开的至少一个实施例提供了再一种显示模组，其包括：显示面板10以及控光面板20。显示面板10和控光面板20层叠设置；显示面板10位于控光面板20的出光侧；显示面板10包括至少部分位于(例如，全部位于或部分位于)显示模组01的显示区域的第三公共电极140；第三公共电极140被复用为显示模组01的触控电极。
例如，通过使得显示面板10包括位于显示模组01的显示区域的第三公 共电极140被复用为显示模组01的触控电极，可以在使得不增加额外的电极层的情况下使得显示模组01具有触控功能。
图25是本公开的至少一个实施例提供的再一种显示模组01的第一个示例的示意图。例如，如图25所示，该显示模组01包括显示面板10、背光单元30以及控光面板20，显示面板10、控光面板20和背光单元30在第三方向D3上层叠设置(例如，顺次设置)；显示面板10位于控光面板20的出光侧；背光单元30位于控光面板20远离显示面板10的一侧。
例如，如图25所示，显示面板10包括位于显示模组01的显示区域的第三公共电极140；第三公共电极140被复用为显示模组01的触控电极。
例如，通过使得显示面板10包括位于显示模组01的显示区域的第三公共电极140被复用为显示模组01的触控电极，可以在使得不增加额外的电极层的情况下使得显示模组01具有触控功能。
图26是图25所示的第三公共电极140和第一触控走线143的平面示意图。例如，如图26所示，第三公共电极140包括多个阵列排布的自电容电极142。
需要说明的是，图26示出的第三公共电极140第一触控走线143仅用于说明自电容电极142、第一触控走线143和第一柔性电路板120的电连接关系，但本公开的至少一个实施例的第三公共电极140的排布和第一触控走线143的排布不限于图26所示的排布。
例如，如图26所示，显示模组01还包括至少一个第一柔性电路板120；显示面板10还包括第一触控走线143；至少一个第一柔性电路板120包括多根第三走线122；多根第三走线122的每个的第一端经由对应的第一触控走线143与对应的自电容电极142电连接，多根第三走线122的每个的第二端与对应的第一电路板110电连接。
例如，如26所示，第一柔性电路板120还包括第一芯片123。例如，第一芯片123可以是触控与显示驱动器集成(Touch and Display Driver Integration，TDDI)。例如，第一芯片123被配置为经由该第一柔性电路板120包括多根第三走线122向对应的自电容电极142施加驱动信号，第一芯片123还被配置为经由该第一柔性电路板120包括的多根第三走线122接收对应的自电容电极142提供的反馈信号(触控感应信号)，并基于反馈信号确认是否有自电容电极142被触摸以及被触摸的自电容电极142所处的位置(也即， 触控位置)。
例如，多根第三走线122的每根可以包括在第二方向D2上并列布置的两根第三子走线；至少部分位于第一触控走线143和第一芯片123之间的第三子走线的两端分别与第一触控走线143和第一芯片123电连接；至少部分位于第一电路板110和第一芯片123之间的第三子走线的两端分别与第一电路板110和第一芯片123电连接。
例如，如图25所示，显示面板10还包括第一阵列基板151、第一液晶层153和第一对置基板152；控光面板20包括第二阵列基板251、第二液晶层253、第二对置基板252和第二屏蔽层282。例如，如图25所示，背光单元30、第二阵列基板251、第二液晶层253、第二对置基板252、第二屏蔽层282、第一阵列基板151、第一液晶层153和第一对置基板152在第三方向D3上顺次设置。例如，如图25所示，第一阵列基板151包括第三公共电极140。例如，第三公共电极140和第二屏蔽层282可以由透明导电氧化物制成。例如，透明导电氧化物可以为铟锡金属氧化物或其它适用的材料。
本公开的发明人在研究中注意到，对于图25所示的显示模组01，显示面板10包括第三公共电极140和第二屏蔽层282之间存在固定电容，并且，第三公共电极140和第二屏蔽层282之间存在固定电容对对图25所示的显示模组01的触控效果产生了不利影响。
本公开的发明人在研究中注意到，对于图25所示的显示模组01，可以通过以下三种方法的至少一种来抑制显示面板10包括第三公共电极140和第二屏蔽层282之间的固定电容对显示模组01的触控效果的不利影响。方法一是提升触控判定阈值。方法二是增加第三公共电极140和第二屏蔽层282之间的间距以降低第三公共电极140和第二屏蔽层282之间的固定电容。例如，可以通过在第一阵列基板151和第二对置基板252之间设置绝缘层来增加第三公共电极140和第二屏蔽层282之间的间距。方法二是将基于自电容实现触控转变为基于互电容实现触控。下面结合图26和图27A对上述方法三进行示例性说明。
图27A是图25所示的第三公共电极140和第二屏蔽电极层281的平面示意图。例如，如图27A所示，第三公共电极140包括在第二方向D2上并列布置的多个第一条状电极141；第二屏蔽层282包括在第一方向D1上并列布置的多个第三条状电极282a；多个第一条状电极141和多个第三条状电极 282a作为整体被复用为基于互电容的触控电极。例如，多个第一条状电极141和多个第三条状电极282a产生阵列排布的多个互电容。当手指触碰屏幕时，位于手指对应区域的互电容的电容值会发生改变。
图27B示出了图27A所示的第三公共电极140和第二屏蔽电极层281与第一柔性电路板和第二柔性电路板电连接关系的示例。
在第一个示例中，如图27B所示，多个第三条状电极282a可以经由第二触控走线243与第二柔性电路板220包括的第四走线222电连接；多个第一条状电极141可以经由第一触控走线241与第一柔性电路板120包括的第三走线122电连接。例如，多个第一条状电极141可以为触控驱动电极，多个第三条状电极282a可以为触控感应电极；此种情况下，第一柔性电路板120上的第一芯片123可以经由第一柔性电路板120向触控驱动电极(也即，第一条状电极141)提供触控驱动信号，第二柔性电路板220的第二芯片223可以经由第二柔性电路板220接收触控感应电极(也即，第三条状电极282a)提供的触控感应信号。例如，第二芯片223可以基于手指触摸前后触控感应信号的变化情况确定手指触摸点的位置。又例如，多个第一条状电极141可以为触控感应电极，多个第三条状电极282a可以为触控驱动电极。
在第二个示例中，多个第三条状电极282a可以经由第二触控走线243与第一柔性电路板120包括的第四走线222电连接，多个第一条状电极141可以经由第一触控走线241与第一柔性电路板120包括的第三走线122电连接。例如，多个第一条状电极141可以为触控驱动电极，多个第三条状电极282a可以为触控感应电极；此种情况下，第一柔性电路板120上的第一芯片123可以经由第一柔性电路板120向触控驱动电极(也即，第一条状电极141)提供触控驱动信号，经由第一柔性电路板120接收触控感应电极(也即，第三条状电极282a)提供的触控感应信号，并基于手指触摸前后触控感应信号的变化情况确定手指触摸点的位置。又例如，多个第一条状电极141可以为触控感应电极，多个第三条状电极282a可以为触控驱动电极。
例如，由于基于互电容实现触控是通过检测触控驱动电极和触控感应电极之间的信号变化值，因此，基于互电容实现触控的显示模组01的抗干扰能力更强。例如，由于第三公共电极140和第二屏蔽层282之间的间距较小，第三公共电极140和第二屏蔽层282之间的电容较大，因此，在多个第一条状电极141的宽度和多个第三条状电极282a的宽度较小的情况下，第三公共 电极140和第二屏蔽层282之间的电容也能实现良好的触控效果，此种情况下，可以提高显示模组01的触控分辨率。例如，可以通过基于同一个衬底基板制作第一阵列基板151和第二对置基板252来进一步地降低第三公共电极140和第二屏蔽层282之间的间距，由此可以进一步地提高显示模组01的触控分辨率。
例如，显示面板10包括位于显示模组01的显示区域的第三公共电极140；控光面板20包括至少部分位于(例如，全部位于或部分位于)显示模组01的显示区域的第四公共电极240；第三公共电极140和第四公共电极240位于显示模组01包括的第一液晶层153和第二液晶层253之间。下面结合图28-图30进行示例性说明。例如，通过使得第三公共电极140和第四公共电极240位于显示模组01包括的第一液晶层153和第二液晶层253之间，可以提升第三公共电极140和第四公共电极240之间的电容以及显示模组01的触控分辨率。
图28是本公开的至少一个实施例提供的再一种显示模组01的第二个示例的示意图。例如，如图28所示，该显示模组01包括显示面板10、背光单元30以及控光面板20，显示面板10、控光面板20和背光单元30在第三方向D3上层叠设置(例如，顺次设置)；显示面板10位于控光面板20的出光侧；背光单元30位于控光面板20远离显示面板10的一侧。例如，如图28所示，显示面板10还包括第一阵列基板151、第一液晶层153和第一对置基板152；控光面板20包括第二阵列基板251、第二液晶层253、第二对置基板252和第二屏蔽层282。
例如，如图28所示，显示面板10包括位于显示模组01的显示区域的第三公共电极140；控光面板20包括位于显示模组01的显示区域的第四公共电极240。
图29A是图28所示的显示面板10包括的第三公共电极140和控光面板20的第四公共电极240的平面示意图。
例如，如图29A所示，第三公共电极140包括在第二方向D2上并列布置的多个第一条状电极141；第四公共电极240包括在与第一方向D1交叉的第二方向D2上并列布置的多个第二条状电极241；多个第一条状电极141和多个第二条状电极241作为整体被复用为基于互电容的触控电极。
例如，如图28所示，第三公共电极140和第四公共电极240位于第一液 晶层153和第二液晶层253之间。例如，如图28所示，第三公共电极140和第四公共电极240分别位于第一阵列基板151和第二阵列基板251中。
例如，第三公共电极140和第四公共电极240之一可以作为触控驱动电极层，第三公共电极140和第四公共电极240另一个可以作为触控感应电极层。
图29B示出了图29A所示的第三公共电极和第四公共电极与第一柔性电路板和第二柔性电路板电连接关系的示例。
在第一个示例中，第三公共电极140可以作为触控驱动电极层，第四公共电极240作为触控感应电极层；对应地，多个第一条状电极141可以为触控驱动电极，多个第二条状电极241可以为触控感应电极。例如，如图29B所示，多个第二条状电极241可以经由第二触控走线243与第二柔性电路板220包括的第四走线222电连接；此种情况下，第一柔性电路板120上的第一芯片123可以经由第一柔性电路板120向触控驱动电极(也即，第一条状电极141)提供触控驱动信号，第二柔性电路板220的第二芯片223可以经由第二柔性电路板220接收触控感应电极(也即，第二条状电极241)提供的触控感应信号。例如，第二芯片223可以基于手指触摸前后触控感应信号的变化情况确定手指触摸点的位置。
在第二个示例中，第三公共电极140可以作为触控感应电极层，第四公共电极240作为触控驱动电极层；对应地，多个第一条状电极141可以为触控感应电极，多个第二条状电极241可以为触控驱动电极。例如，如图29B所示，多个第二条状电极241可以经由第二触控走线243与第二柔性电路板220包括的第四走线222电连接；此种情况下，第二柔性电路板220的第二芯片223可以经由第二柔性电路板220向触控驱动电极(也即，第二条状电极241)提供触控驱动信号，第一柔性电路板120上的第一芯片123可以经由第一柔性电路板120接收触控感应电极(也即，第一条状电极141)提供的触控感应信号。例如，第一芯片123可以基于手指触摸前后触控感应信号的变化情况确定手指触摸点的位置。
需要说明的是，对于上述两个示例，第三公共电极和第四公共电极还可以与同一个芯片(例如，第一芯片123或第二芯片223)电连接，在此不再赘述。
例如，对于上述两个示例，显示面板10和控光面板20可以均具有触控 保持(holding)功能。此处，触控保持功能是指：在每个触控阶段开始时，面板的行扫描终止，以及在每个触控阶段结束时，面板的行扫描从扫描终止的位置处再次开始。例如，在显示面板10和控光面板20均具有触控保持功能的情况下，显示面板10和控光面板20的触控阶段同步，也即，显示面板10和控光面板20的行扫描同时结束，并同时再次开始。
例如，对于上述两个示例，控光面板20具有触控保持功能但显示面板不具有触控保持功能；此种情况下，多个第一条状电极141可以为触控感应电极，多个第二条状电极241可以为触控驱动电极。
本公开的发明人在研究中注意到，在控光面板20具有触控保持功能但显示面板不具有触控保持功能的情况下，触控操作导致的第三公共电极240包括的至少部分第一条状电极141上的电信号变化导致显示模组01发出的光线的强度存在随时间波动的问题。
例如，可以将向多个第二条状电极241施加触控驱动信号，提取从多个第一条状电极141获取的信号的波动值，并将上述波动值用于对显示模组01的亮度进行补偿，以抑制触控操作导致的显示模组01发出的光线的强度存在随时间波动问题。
例如，对于图28所示的显示模组01，第二对置基板252、第二液晶层253、第二阵列基板251、第一阵列基板151、第一液晶层153和第一对置基板152在第三方向D3上顺次设置；第一阵列基板151包括第三公共电极140；第二阵列基板251包括第四公共电极240；第一阵列基板151和第二阵列基板251位于第一液晶层153和第二液晶层253之间。例如，图28所示的显示模组01可以是基于高级超维场转换技术(Advanced Super Dimension Switch，ADS)的显示模组。
图30是本公开的至少一个实施例提供的再一种显示模组01的第三个示例的示意图。图30所示的显示模组01与图28所示的显示模组01显示模组01相似，区别包括图30所示的显示模组01的第三公共电极140和第四公共电极240分别位于第一对置基板152和第二对置基板252中，而不是位于第一阵列基板151和第二阵列基板251中。例如，对于图30所示的显示模组01，第二阵列基板251、第二液晶层253、第二对置基板252、第一对置基板152、第一液晶层153和第一阵列基板151在第三方向D3上顺次设置；第一对置基板152和第二对置基板252位于第一液晶层153和第二液晶层253之间，由 此，第三公共电极140和第四公共电极240也位于第一液晶层153和第二液晶层253之间。例如，图30所示的显示模组01可以是基于垂直配向技术(vertical alignment，VA)的显示模组。
图31是本公开的至少一个实施例提供的再一种显示模组01的第四个示例的示意图。图30所示的显示模组01与图28所示的显示模组01显示模组01相似，区别包括第二对置基板252、第二液晶层253、第二阵列基板251、第一对置基板152、第一液晶层153和第一阵列基板151在第三方向D3上顺次设置，由此使得第一阵列基板151包括的第三公共电极140以及第二阵列基板251包括的第四公共电极240在控光面板20和显示面板10叠置的方向(也即，第三方向D3)上位于第二液晶层253的两侧。
需要说明的是，本公开的至少一个实施例提供了再一种显示模组也可以通过以下两种方法的至少一种来降低因摩擦导致的显示模组的显示不良的可能性：使得用于显示面板10的至少一个第一电路板110的任一个以及用于控光面板20的至少一个第二电路板210(例如，全部的第二电路板210)在垂直于第一面的方向上不重叠；至少一个第一柔性电路板120在第一面上的正投影的任一个与至少一个第二柔性电路板220(例如，全部的第二柔性电路板220)在第一面上的正投影在垂直于第一面的方向上不重叠。具体请见图3-图23B所示的显示模组01(或显示模组01的组件)，在此不再赘述。
本公开的至少一个实施例还提供了一种显示装置。图32是本公开至少一个实施例提供的显示装置的示例性框图。如图32所示，该显示装置包括本公开的至少一个实施例提供的任一显示模组。
需要说明的是，对于该显示装置的其它组成部分(例如，图像数据编码/解码装置、时钟电路等)可以采用适用的部件，这些均是本领域的普通技术人员所应该理解的，在此不做赘述，也不应作为对本公开的限制。本公开的任一实施例提供的显示装置可以为：手机、平板电脑、电视机、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。
虽然上文中已经用一般性说明及具体实施方式，对本公开作了详尽的描述，但在本公开实施例基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本公开精神的基础上所做的这些修改或改进，均属于本公开要求保护的范围。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范 围，本公开的保护范围由所附的权利要求确定。
