Description

显示面板和其制作方法以及显示装置
本申请要求于2018年12月05日提交中国专利局，申请号为201811476658.4，申请名称为“一种显示面板和其制作方法以及显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示面板和其制作方法以及显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。
液晶显示屏由于其液晶分子的轴向透光特性，在解决大视角色偏的技术课题上一直有新的解法出现。目前广视角主流技术多为FFS(Fringe Field Switching，边缘场开关技术)，IPS(In-Plane-Switching，平面方向转换)与MVA(Multi-domain Vertical Alignment，多象限垂直配向)阵营。MVA技术较早投入应用在广视角的液晶面板，是利用突出物使液晶静止时偏向于某一个角度，而并非传统面板中的直立静止状态，如此一来，当施加电压让液晶分子改变成水平状态以便背光穿过时，其背光的穿透速度更快，因而可大幅缩短显示时间。
运用MVA模式来设计穿透式显示器时，为了提升画面显示的视角范围，显示器中的液晶往往以多重区域的方式进行排列，但是，这种多重液晶区域的排列方式会使显示器在穿透状态时穿透率不高，易在大视角时出现背景画面泛白或者出现色偏，从而影响画面质量。

下面参考附图和实施例对本申请作进一步说明。
如图1至图6所示，本申请公布了一种显示面板100，包括：第一基板110，平行于第一基板110设置的第二基板120和形成于第一基板110和第二基板120之间的像素单元130；所述像素单元130包括至少两种透光区140和液晶材料150填充在所述透光区140；每种所述透光区140填充的所述液晶材料150的穿透率不同。
本方案中，利用不同穿透率的液晶材料150分别运用在不同的透光区140，区分多个透光亮暗区，达成改善色偏的效果，在大视角观看下会有多范畴补偿的效果。等效区分多个区域取代了传统的电压分压的方式，减少制程，以及电压对液晶驱动时需要的功耗，更省能。
在一实施例中，所述液晶材料150，包括：第一液晶材料151，第二液晶材料152和第三液晶材料153；所述透光区140包括：第一透光区141，第二透光区142和第三透光区143；所述第一液晶材料151注入于所述第一透光区141，所述第二液晶材料152注入于第二透光区142，所述第三液晶材料153注入于第三透光区143；此处第一透光区141，第二透光区142和第三透光区143分别为主透光区，次透光区，和次二透光；但不对透光区做任何限定，主透光区也可以是第二透光区142或第三透光区143。
如图3至图5所示，本方案中，三种透光区分别对应的三种不同液晶材料150，使三种透光区的穿透率不同，改善色偏。第一透光区141喷涂第一液晶材料151，第二透光区142,喷涂第二液晶材料152，第三透光区143喷涂第一液晶材料153,又因为三种液晶材料的穿透率不同，第一液晶材料151大于第二液晶材料152大于第三液晶材料，因此三种透光区，相互平衡改善色偏或大视角时灰阶泛白的情况；三种透光区140的穿透率分别更加明显。
如图2和图5所示，在一实施例中，所述显示面板100还包括扫描线160、数据线和主动开关，所述数据线与扫描线160与所述主动开关连接，所述扫描线160和数据线相互垂直设置；所述第一透光区141，第二透光区142和第三透光区143均设置在所述扫描线160同一侧。
本方案中，透光区140在同一侧，因为扫描线160跟主动开关180连接，当施加电压驱动液晶分子状态，其背光的穿透速度更快，因而可大幅缩短显示时间。
在一实施例中，三种所述透光区140距离主动开关180位置越远，透光率越小。
本方案中，透光区140距离主动开关180位置越远，穿透率越小，对主动开关180的公共电压影响较小，因为穿透率越高需要的电压越多。
如图5所示，在一实施例中，所述第一透光区141，第二透光区142和第三透光区143的面积相同。
本方案中，开口率是像素的有效透光区面积与像素总面积的比值，三种透光区140的面积相同，其开口率互不影响，在大视角时可有效压制中灰阶泛白的情况。
如图2和图6所示，在一实施例中，所述显示面板100还包括扫描线160、数据线170和主动开关180，所述数据线170与扫描线160与所述主动开关180连接，所述扫描线160和数据线170相互垂直设置；所述第二透光区142设置在所述扫描线160一侧、所述第一透光区141和第三透光区143设置扫描线160的另一侧。
本方案中，所述第二透光区142设置在所述扫描线160一侧、所述第一透光区141和第三透光区143设置扫描线160的第二侧。多重区域分别通过不同的扫描线驱动，因为面积不同所需要得电压不同，所以分别用不同扫描线160和数据线170。
如图6所示，在一实施例中，三种所述透光区依特定面积比例区分，所述第一透光区141的面积与第三透光区143的面积之比为1比1；所述第二透光区142的面积与所述第一透光区141和第三透光区143面积之合的面积比为3比2。
本方案中，这样区分成的像素透光区，以产生多个场域，达到多域分割的效果。从而使得透明显示器处于穿透模式时，减轻绕射影响以提高像素穿透率，改善背景画面出现色偏的情况。
如图1至图6所示，作为本申请的另一实施例，还公开一种显示面板100，包括：
第一基板110，平行于第一基板110设置的第二基板120和形成于第一基板110和第二基板120之间的像素单元130；所述像素单元130包括至少两种透光区140和液晶材料150填充在所述透光区140；每种所述透光区140填充的所述液晶材料150的穿透率不同。所述液晶材料，包括：第一液晶材料151，第二液晶材料152和第三液晶材料153；所述第一液晶材料151注入于所述第一透光区141，所述第二液晶材料152注入于第二透光区142，所 述第三液晶材料153注入于第三透光区143.
所述显示面板还包括扫描线160、数据线170和主动开关180，所述数据线170与扫描线160与所述主动开关180连接，所述扫描线160和数据线170相互垂直设置；
所述第二透光区设置在所述扫描线160第一侧、所述第一透光区和第三透光区设置扫描线160的第二侧。
三种所述透光区140依特定面积比例区分，所述第一透光区141的面积与第三透光区143的面积之比为1比1；所述第二透光区142的面积与所述第一透光区141和第三透光143区面积之和的面积比为3比2。
在一实施例中，所述液晶材料中其中一种为安息香酸酯类材料。。
本方案中，这类液晶化合物中心部两个苯环之间由酯类连接，液晶稳定性好以及粘度高。本申请液晶材料也可以联苯类和联三苯类和苯基环己烷基类和联苯基环基类，视面板情况决定。
如图7所述，作为本申请的另一实施例，还公开一种显示面板的制作方法，步骤包括，
S71、在第一基板和第二基板之间形成多个像素单元；
S72、在每个所述像素单元中划分至少两种透光区；
S73、在每种所述透光区注入不同穿透率的液晶材料。
在一实施例中，所述在每种所述透光区注入不同穿透率的液晶材料的步骤包括：采用喷涂的方式将所述液晶材料注入所述透光区。
本方案中，调整液晶准注入的传统工艺，其他工艺流程却不放改变，因需要在三种区域内注入不同的液晶材料140，喷涂(inkjet)方式相对于传统更易实现，能在改善色偏的基础上，快速注入液晶，提高产能。
本实施方式的制作方法适用于本申请任意所述的显示面板100。
如图8所示，作为本申请的另一实施例，还公开一种显示装置400，包括上述任意显示面板100。
需要说明的是，本方案中涉及到的各步骤的限定，在不影响具体方案实施的前提下，并不认定为对步骤先后顺序做出限定，写在前面的步骤可以是在先执行的，也可以是在后执行的，甚至也可以是同时执行的，只要能实施本方案，都应当视为属于本申请的保护范围。
本申请的技术方案可以广泛用于各种显示面板，如TN型显示面板(全称为Twisted Nematic，即扭曲向列型面板)、IPS型显示面板(In-Plane Switching，平面转换)、VA型显示面板(Multi-domain Vertica Aignment，多象限垂直配向技术)，当然，也可以是其他类型的显示面板，如有机发光显示面板(organic light emitting diode，简称OLED显示面板)，均可适用上述方案。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
