具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方 案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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他实施例，都属于本公开保护的范围。
本公开是基于发明人对于以下事实和问题的发现和认识作出的。液晶显示器存在对比度较低的问题。例如，ADS显示模式的液晶显示器的对比度只能维持在1200左右的较低水平。发明人发现，目前用于提高ADS显示模式的液晶显示器对比度的方法只是在如偏光片、液晶等材质上做改进，未有明显的改善。此外，发明人发现，降低显示面板显示画面亮度最小的位置处的透光率来提高ADS模式液晶显示器对比度的方法，并不会使显示画面中亮度最大的位置处的透光率提高，由此，上述方法提高对比度的程度较低。综上，液晶显示器的对比度较低，严重影响显示器的显示效果，进而影响用户的观看效果。
本公开旨在至少一定程度上缓解或解决上述提及问题中至少一个。
在本公开的一个方面，本公开提出了一种显示装置。在一些实施例中，参考图1，该显示装置包括：液晶盒100以及光阀控制器200。其中，液晶盒100包括对向设置的第一基板110(例如，阵列基板)以及第二基板120(例如，彩膜基板)。光阀控制器200位于第一基板110远离第二基板120的一侧，光阀控制器200包括对向设置的下基板210、上基板220，以及布置在上基板220和下基板210之间的液晶分子230。在一些实施例中，液晶盒100包括多个呈阵列排布的显示子像素10(如图1中的虚线框10所示)，光阀控制器200包括多个呈阵列排布的控制子像素20(如图1中的虚线框20所示)，显示子像素10以及控制子像素20一一对应设置。由此，该显示装置具有较高的对比度，显著提高显示装置的显示效果以及用户观看效果。
在本公开的实施例中，以第一基板110是阵列基板、第二基板120是彩膜基板为例进行说明。本领域技术人员能够理解，第一基板110也可以是彩膜基板，第二基板120也可以是阵列基板。本领域技术人员能够理解的是，液晶盒100还可以包括布置在阵列基板110以及彩膜基板120之间的液晶分子，以便实现显示装置的显示功能。
在一些实施例中，显示子像素10以及控制子像素20一一对应设 置。每一个显示子像素10在下基板上的正投影和对应的控制子像素20在下基板上的正投影重合；并且，每一个控制子像素20在阵列基板上的正投影也和对应的显示子像素10在阵列基板上的正投影相重合。
为了便于理解，下面首先对根据本公开实施例的显示装置进行简单说明。
如前所述，目前ADS显示模式的液晶显示器由于对比度较低，导致其显示效果较差，影响用户观看效果。而目前用于提高ADS显示模式的液晶显示器对比度的方法，主要是在材质的改进方面，其提高对比度的效果未有明显改善。
根据本公开的实施例，在液晶盒与背光模组之间设置光阀控制器。利用相同的电路控制光阀控制器与液晶盒。在光线进入液晶盒之前，预先利用光阀控制器先一步调节入射至液晶盒中的背光的亮度，使液晶盒不同位置处接收到的背光的亮度不同。由此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗，以显著提高显示装置的对比度。
例如，在理论上，根据本公开实施例的显示装置的对比度，能够达到仅使用单个液晶盒进行显示时可以达到的对比度的平方。
具体地，如前所述，显示子像素和控制子像素是一一对应设置的，背光模组中射出的光线先经过光阀控制器中的控制子像素调节灰阶，以使射入到液晶盒的光线具有不同的灰阶。例如，可以通过调节光阀控制器中，和显示画面中最亮的区域所对应的位置处的液晶分子的偏转情况，保证背光的亮度不发生改变，从光阀控制器射出，入射至液晶盒中。由此，经过光阀控制器中液晶分子的调节，光阀控制器对应于显示画面中最暗的区域的位置射出的背光具有最暗的灰阶。具有不同灰阶的光线进入液晶盒后，继续经液晶盒中的显示子像素进行调节，以使显示画面中亮度最大的区域的灰阶达到背光模组最亮的灰阶，显示画面中亮度最小的区域的灰阶在经过光阀控制器调节后达到最暗。由此，在保证显示装置亮度的同时，可以显著提高显示装置的对比度。相较于现有技术对灰阶的调节，根据本公开实施例的显示装置是通过两次液晶偏转调节的，即控制子像素液晶分子偏转以及显示子像素液晶分子偏转。而现有技术只是利用显示子像素液晶分子的偏转进行调节。因此，根据本公开实施例的显示装置的显示画面中亮度最大和亮 度最小的灰阶级别差距更大，可以具有更高的对比度。
下面根据本公开的具体实施例，对该显示装置的各个结构进行详细说明。
在一些实施例中，参考图2，液晶盒100的第一基板110(例如，阵列基板)上设置有多个用于控制显示子像素10的第一像素电极111，光阀控制器200的下基板210上设置有多个用于控制控制子像素20的第二像素电极211，且第一像素电极111在下基板210上的正投影与第二像素电极211在下基板210上的正投影重合。
根据本公开实施例的显示装置，在光线进入液晶盒之前，预先利用光阀控制器，先一步调节入射至液晶盒中的背光的亮度，使液晶盒不同位置处接收到的背光的亮度不同。由此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗，以显著提高显示装置的对比度。
可选地，第一像素电极111与第二像素电极211控制显示子像素10中的液晶分子和对应的控制子像素20中的液晶分子具有相同的偏转程度以实现相同的灰阶。例如，第一像素电极111与第二像素电极211在下基板210上的正投影重合(即，阵列基板上的电极分布情况与下基板上的电极分布情况完全一致)，则仅需要对两个基板施加相同的电压信号，既可以保证液晶分子偏转情况一致。由此，一方面，两组电极的投影重合，整个显示装置透光率较高；另一方面，两个基板可以利用完全相同的生产线进行制备；再一方面，可以将两块基板连接相同的电压信号，进而还有利于简化控制电路。
在一些实施例中，上基板220可以设置有第二公共电极221。由此，可以利用第二公共电极与第二像素电极产生电场，控制上基板以及下基板之间的液晶分子发生旋转，调节控制子像素的亮度。关于第二公共电极与上基板的位置关系不受特别限制，本领域技术人员可以根据具体情况进行设计。例如，在一些实施例中，第二公共电极221可以位于上基板220面对下基板210的一侧。或者根据本公开的另一些实施例，第二公共电极还可以位于上基板远离下基板的一侧。
在一些实施例中，彩膜基板120上设置有第一公共电极121，第一公共电极121位于彩膜基板120面对阵列基板110的一侧。由此，可以利用第一公共电极与第一像素电极产生电场，控制液晶盒中的液晶 分子发生旋转，调节显示子像素的亮度。在一些实施例中，上基板220设置有第二公共电极221，彩膜基板120设置有第一公共电极121，且第二公共电极221与第一公共电极121在下基板210上的正投影重合。如前所述，可选地，第一像素电极111与第二像素电极211控制显示子像素10中的液晶分子和对应的控制子像素20中的液晶分子具有相同的偏转程度。由此，一方面，两组电极的投影重合，整个显示装置透光率较高；另一方面，两个基板可以利用完全相同的生产线进行制备；再一方面，可以将两块基板连接相同的电压信号，进而还有利于简化控制电路。
在一些实施例中，显示子像素10由第一公共电极121、第一像素电极111以及布置在第一公共电极121与第一像素电极111之间的液晶分子构成；控制子像素20由第二公共电极221、第二像素电极211以及布置在第二公共电极221与第二像素电极211之间的液晶分子230构成。如前所述，根据本公开的实施例，第二公共电极221与第一公共电极121对应设置，第二像素电极211与第一像素电极111对应设置。由此，可以使控制子像素与显示子像素一一对应设置，进而在给光阀控制器以及液晶盒施加相同电信号时，能够使液晶盒不同位置处接收到的背光的亮度不同。由此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗。并且，由于光阀控制器中控制子像素，和液晶盒中的显示子像素是一一对应的，因此根据本公开实施例的显示装置，可以在子像素的尺度上调节对比度，进而可以显著提高显示装置的对比度。
在一些实施例中，如图2所示，所述下基板210位于所述上基板220远离所述液晶盒100的一侧；所述下基板210设置有第一偏光片2121，所述上基板220和所述第一基板110之一设置有第二偏光片2122，所述第二基板120设置有第三偏光片2123。可选地，所述第三偏光片2123的偏光方向与所述第一偏光片2121的偏光方向相同。由此，可以对背光模组入射至光阀控制器的光进行起偏，并使最终从液晶盒100透出的光线能够被人眼所观察到。
在一些实施例中，如图3所示，该显示装置还可以包括：背光模组300，背光模组300位于光阀控制器200远离液晶盒100的一侧。背光模组300为显示装置的光源，从而实现显示装置的显示功能。在一 些实施例中，如图3所示，背光模组300还可以包括多个光学膜片，例如310A、310B，光阀控制器200位于背光模组300设置有光学膜片310的一侧，由此，光阀控制器200内嵌在背光模组300与液晶盒100之间。在一些实施例中，光阀控制器200以及液晶盒100分别独立的设置有驱动器30，以使光阀控制器、液晶盒中产生电场，控制液晶分子的旋转。
在一些实施例中，如图2所示，该显示装置还可以包括：电路控制单元400。电路控制单元400分别与第一像素电极111以及第二像素电极211相连。电路控制单元400被设置为向第一像素电极111以及第二像素电极211输入相同的信号。由此，可以显著提高显示装置的对比度。
下面根据本公开的具体实施例，对该显示装置的工作原理进行详细说明。
在一些实施例中，参考图4，该显示装置包括三个偏光片：位于下基板远离上基板一侧的第一偏光片2121，位于阵列基板远离彩膜基板一侧的第二偏光片2122，以及位于彩膜基板远离阵列基板一侧的第三偏光片2123。本领域技术人员能够理解的是，上述三个偏光片的偏振方向，只要可以实现背光能够经过光阀控制器以及液晶盒射出，实现显示即可。例如，三个偏光片可以具有相同的偏光方向。在一些实施例中，第三偏光片2123的偏光方向与第一偏光片2121的偏光方向相同，而第二偏光片2122的偏光方向与上述两个偏光片的偏光方向垂直。根据本公开的具体实施例，第一偏光片2121透过轴的角度可以为90°，第二偏光片2122透过轴的角度可以为0°，第三偏光片2123透过轴的角度可以为90°。
根据本公开的具体实施例，参考图4以及图5，第一偏光片2121透过轴的角度为90°，第二偏光片2122透过轴的角度为0°，第三偏光片2123透过轴的角度为90°。光阀控制器中的液晶分子偏转90度时，射出光阀控制器的背光亮度可以达到最亮；光阀控制器中的液晶分子偏转0度时，射出光阀控制器的背光亮度可以达到最暗。在图4所示的实施例中，灰色箭头指示自然光，白色箭头指示偏振方向为90°的偏振光，黑色尖头指示偏振方向为0°的偏振光。
在一些实施例中，显示装置显示时，在显示画面中亮度最大的位 置(例如图5中示出的L255)，给光阀控制器的控制子像素以及液晶盒的显示子像素均施加VOP电压(VOP为使液晶分子发生旋转的最大电压，如特定地为令液晶分子偏转90度时的电压)。如图4所示，背光模组300发出的自然光301透过所述第一偏光片2121后进入光阀控制器200，自然光311偏转为与所述第一偏光片2121偏振方向一致的偏振光。例如，所述第一偏光片2121的透过轴为90°，自然光311透过所述第一偏光片2121后偏转为偏振角度为90°的偏振光312。控制子像素20中的液晶分子在VOP电压下会发生90°的偏转，从而偏振角度为90°的偏振光312经过施加VOP电压的液晶分子后，会偏转为偏振角度为0°的偏振光313。所述第二偏光片2122的透过轴角度为0°，所述第三偏光片2123的透过轴角度为90°。由此，偏振光313可以穿过所述第二偏光片2122进入液晶盒100中。显示子像素10中的液晶分子在VOP电压下发生90°偏转，偏振角度为0°的偏振光314经过显示子像素10中的液晶分子后，会偏转为偏振角度为90°的偏振光315。偏振角度为90°的偏振光315与所述第三偏光片2123的偏振方向一致。由此，偏振角度为90°的偏振光315可以被人眼观察到。
在一些实施例中，显示装置显示时，在显示画面中亮度最小的位置(例如图5中示出的L0)，不向光阀控制器中的控制子像素以及液晶盒中的显示子像素施加电压，也即是说，控制子像素以及显示子像素中的电压为0。如图4所示，背光模组300中发出的自然光321透过所述第一偏光片2121后进入光阀控制器200，自然光321偏转为与所述第一偏光片2121偏振方向一致的偏振光322。例如，所述第一偏光片2121的透过轴为90°，自然光321透过所述第一偏光片2121后偏转为偏振角度为90°的偏振光322。控制子像素20中的液晶分子不发生偏转，从而偏振角度为90°的偏振光322经过控制子像素中的液晶分子后偏振角度不变，仍为偏振角度为90°的偏振光323。所述第二偏光片2122的透过轴角度为0°，所述第三偏光片2123的透过轴角度为90°。偏振光323的偏振角度与所述第二偏光片2122的透过轴角度垂直。由此，偏振角度为90°的偏振光323被所述第二偏光片2122吸收，残余的偏振光324透过所述第二偏光片2122进入液晶盒100中。显示子像素10中的液晶分子在0电压下不发生偏转，从而残余的偏振光324经过显示子像素10中的液晶分子后偏振角度不变，为偏振角度 为0°的偏振光325。残余偏振光325的偏振角度与所述第三偏光片2123的偏振方向垂直。由此，残余偏振光325会被所述第三偏光片2123吸收，使显示画面亮度最小的位置处呈现更黑的亮度。利用以上布置，可以使显示画面亮度最小的位置处的亮度更暗，以显著降低显示画面亮度最小的位置处的透光率。
根据本公开的实施例，光阀控制器包括下基板、上基板以及液晶分子，下基板设置有偏光片以及控制液晶分子的第二像素电极，上基板设置有第二公共电极，光阀控制器中的控制子像素与液晶盒中的显示子像素一一对应设置。给光阀控制器以及液晶盒施加相同的电信号，能够使液晶盒不同位置处接收到的背光的亮度不同。由此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗。在背光进入液晶盒之前先一步调节对比度，以获得仅使用单个液晶盒进行显示时可以达到的对比度的平方。根据本公开实施例的具有较高对比度的显示装置的效果如图5所示。需要特别说明的是，图5所示出的对比度(如从L0-L255)仅为示例性的，而不能够理解为该显示装置的对比度仅为256∶1。如前所述，现有技术中ADS显示模式的液晶显示器的对比度只能达到例如1200的水平。在一些实施例中，利用光阀控制器先一步调节对比度，可以达到例如1200×1200＝1440000(即100万)的较高对比度。
根据本公开的实施例，光阀控制器不包括色阻层、黑矩阵等结构。因此，显示画面中亮度最大的位置对光的透过率影响很小。由此，能够在显著降低显示画面中亮度最小位置处透光率的同时，保证显示画面中亮度最大的位置具有较高的透光率。
关于显示装置的显示模式不受特别限制，本领域技术人员可以根据具体情况进行设计。根据不同显示模式的具体情况，在显示装置中设置光阀控制器，利用光阀控制器先一步调节对比度。
在本公开的另一方面，本公开提出了一种光阀控制器。在一些实施例中，该光阀控制器为前面实施例中描述的光阀控制器。由此，该光阀控制器可以显著提高应用该光阀控制器的显示装置的对比度，提高上述显示装置的显示效果。
在本公开的另一方面，本公开提出了一种显示装置的制备方法。在一些实施例中，由该方法制备的显示装置可以为前面描述的显示装 置，由此，由该方法制备的显示装置可以具有与前面描述的显示装置相同的特征以及优点，在此不再赘述。
在一些实施例中，参考图6，该方法包括：S100，提供液晶盒，所述液晶盒包括对向设置的第一基板以及第二基板；以及S200，在所述第一基板远离所述第二基板的一侧设置光阀控制器，所述光阀控制器包括对向设置的上基板、下基板以及布置在所述上基板以及所述下基板之间的液晶分子；其中，所述液晶盒包括多个呈阵列排布的显示子像素，所述光阀控制器包括多个呈阵列排布的控制子像素，所述显示子像素以及所述控制子像素一一对应设置。
在一些实施例中，在步骤S100中，提供液晶盒。关于液晶盒的结构，前面已经进行了详细描述，在此不再赘述。例如，在一些实施例中，液晶盒包括对向设置的阵列基板、彩膜基板，以及布置在阵列基板与彩膜基板之间的液晶分子。阵列基板设置有用于控制显示子像素的第一像素电极，以及阵列基板远离彩膜基板一侧的偏光片。彩膜基板设置有第二公共电极、色阻层、黑矩阵，以及彩膜基板远离阵列基板一侧的偏光片。由此，可以实现液晶盒的显示功能。
在一些实施例中，在步骤S200中，设置光阀控制器。在一些实施例中，光阀控制器位于第一基板(例如，阵列基板)远离第二基板(例如，彩膜基板)的一侧。关于光阀控制器的结构，前面已经进行了详细描述，在此不再赘述。例如，在一些实施例中，光阀控制器包括对向设置的下基板、上基板以及布置在下基板与上基板之间的液晶分子。下基板设置有用于控制控制子像素的第二像素电极，以及下基板远离上基板一侧的偏光片。上基板设置有第二公共电极，以及上基板远离下基板一侧的偏光片。根据本公开的实施例，光阀控制器中的控制子像素与液晶盒中的显示子像素一一对应设置。由此，在光线进入液晶盒之前，预先利用光阀控制器，先一步调节入射至液晶盒中的背光的亮度，使液晶盒不同位置处接收到的背光的亮度不同。因此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗，以显著提高显示装置的对比度。
在一些实施例中，光阀控制器可以是通过以下步骤形成的：提供设置有第二公共电极的所述上基板，以及设置有第二像素电极和偏光片的所述下基板；将所述上基板以及所述下基板对向设置，并将所述 液晶分子布置在所述上基板和所述下基板之间。其中，所述第一公共电极在所述上基板上的正投影与所述第二公共电极在所述上基板上的正投影重合；所述第一像素电极在所述下基板上的正投影与所述第二像素电极在所述下基板上的正投影重合。由此，控制子像素与显示子像素一一对应设置。在给光阀控制器以及液晶盒施加相同的电信号时，能够使液晶盒不同位置处接收到的背光的亮度不同。因此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗，以获得具有较高对比度的显示装置。
在一些实施例中，光阀控制器制备好后，将制备好的光阀控制器与液晶盒进行连接。光阀控制器与液晶盒的连接方式不受特别限制，本领域技术人员可以根据具体情况进行设计。
在一些实施例中，该方法还可以包括提供背光模组，并将背光模组与光阀控制器连接，背光模组位于光阀控制器远离液晶盒的一侧。背光模组与光阀控制器的连接方式也不受特别限制，本领域技术人员可以根据具体情况进行设计。
在一些实施例中，该方法还可以包括设置电路控制单元，电路控制单元与第二像素电极以及第一像素电极相连，并向第二像素电极以及第一像素电极施加相同的电信号。由此，可以获得具有较高对比度的显示装置。
综上，可以利用简单的生产工艺制备光阀控制器，并将光阀控制器与液晶盒进行连接，获得具有较高对比度的显示装置，且光阀控制器不包括色阻层以及黑矩阵等结构，可以进一步简化生产工序。
在本公开的另一方面，本公开提出了一种控制显示装置对比度的方法，该显示装置可以为前面描述的显示装置，由此，该显示装置可以具有与前面描述的显示装置相同的特征以及优点，在此不再赘述。根据本公开的实施例，该方法包括：利用相同的灰阶来控制所述显示子像素以及对应的控制子像素。例如，可以控制显示子像素中的液晶分子和对应的控制子像素中的液晶分子具有相同的偏转程度，从而呈现相同的灰阶。由此，利用简单的方法即可以显著提高显示装置的对比度。
在一些实施例中，控制显示子像素中的液晶分子和对应的控制子像素中的液晶分子具有相同的偏转程度可以是通过以下方法实现的： 在第一公共电极以及第二公共电极上施加相同的公共电压信号；利用电路控制单元，向第一像素电极以及第二像素电极输入相同的信号。由此，利用简单的方法即可使对应设置的显示子像素以及控制子像素中的液晶分子偏转程度一致。在光线进入液晶盒之前，预先利用光阀控制器，先一步调节入射至液晶盒中的背光的亮度，使液晶盒不同位置处接收到的背光的亮度不同。由此，显示画面亮度较大的区域可以接收到亮度较高的背光，而显示画面亮度较小的区域接收的背光较暗，进而可以使显示装置获得较高的对比度。
