Description
技术领域
本发明涉及显示技术领域,具体的,本发明涉及显示装置。
背景技术
目前,手机、平板电脑、智能手表等电子设备的液晶显示(LCD)的显示器件一般都需要采用偏振方向垂直的两片偏光片,来实现液晶层对白色背光源发出的自然光的调制。但是,偏光片透过率低于50%,从而会显著地降低显示器件的出光率,并导致色域不够广。所以,为了实现广色域(Adobe RGB)和宽色域(例如DCI P3),现阶段的显示器件的设计仍有待改进。
发明内容
本发明是基于发明人的下列发现而完成的:
本发明的发明人在研究过程中发现,胆甾相液晶对蓝光的调制会比白光更加精准,所以,选择蓝色背光源并通过由胆甾相液晶形成的液晶层对蓝光的精准调制,从而更好地实现该显示装置的显示控制功能,如此,还无需在显示面板两侧设置偏光片,进而大幅地提升显示装置的出光效率。
有鉴于此,本发明的一个目的在于提出一种无需偏光片、透光率更高且胆甾相液晶对蓝光调制更精准的显示装置。

发明人经过研究发现,本发明实施例的显示装置,其由胆甾相液晶形成的液晶层对蓝光的调制效果会比白光更加精准,所以,无需在显示面板的两侧分别设置偏光片,也可实现对显示装置的出光的控制,从而大幅提升显示装置的出光效率。
另外,根据本发明上述实施例的显示装置,还可以具有如下附加的技术特征:
根据本发明的实施例,所述胆甾相液晶的非寻常光折射率为1.6、寻常光折射率为1.4且螺距为0.3微米。
根据本发明的实施例,所述液晶层的厚度为1~5微米。
根据本发明的实施例,所述蓝色光的中心波长为430~470纳米。
根据本发明的实施例,所述红色彩膜层为红色量子点层或蓝色荧光染料层,所述绿色彩膜层为绿色量子点层或蓝色荧光染料层。
根据本发明的实施例,所述蓝色子像素的蓝色彩膜层为透明的或蓝色吸收型彩膜。
根据本发明的实施例,所述蓝色彩膜层为蓝色吸收型彩膜,所述红色彩膜层和所述绿色彩膜层为蓝色荧光染料层。
根据本发明的实施例,所述红色彩膜层、所述蓝色彩膜层和所述蓝色彩膜层的厚度各自为100~500纳米。

本发明的附加方面和优点将在下面的描述中部分给出,部分将从下面的描述中变得明显,或通过本发明的实践了解到。

具体实施方式
下面详细描述本发明的实施例,本技术领域人员会理解,下面实施例旨在用于解释本发明,而不应视为对本发明的限制。除非特别说明,在下面实施例中没有明确描述具体技术或条件的,本领域技术人员可以按照本领域内的常用的技术或条件或按照产品说明书进行。
在本发明的一个方面,本发明提出了一种显示装置。
根据本发明的实施例,参考图1,该显示装置包括蓝色背光源100和显示面板;其中,显示面板设置在蓝色背光源100的出光侧,且显示面板包括层叠设置的阵列基板210、液晶层230和彩膜基板260,其中,液晶层230由胆甾相液晶组成且可对蓝色光进行调控,并且,彩膜基板260上包括同层设置的红色彩膜层251、绿色彩膜层252和蓝色彩膜层253,其中,红色彩膜层251和绿色彩膜层252为光致发光层,且红色彩膜层251在蓝色光激发下发出红色光,绿色彩膜层252在蓝色光激发下发出绿色光;并且,显示装置不包括上偏光片和下偏光片。
需要说明的是,本文中所有的“蓝光”均指波长在400~480nm之间的蓝色自然光,所以,蓝色背光源100发出的是蓝色自然光而非蓝色偏振光。还需说明的是,图1中仅画出了显示面板中的一个像素单元作为示意,根据本发明的实施例,显示面板200包括的像素单元的具体个数不受特别的限制,本领域技术人员可根据显示装置的实际显示像素分辨率进行相应地设计,在此不再赘述。
本发明的发明人在研究过程中发现,参考图2,通过模拟结果可知,胆甾相液晶的反射光谱(图2中的曲线a)与蓝光光谱(图2中的曲线b)的匹配性非常高,且暗态下的蓝光透过胆甾相液晶的透过率(图2中的曲线c)接近于0%,这些都说明了胆甾相液晶对蓝光的调制会比白光更加精准。所以,选择蓝色背光源并通过由胆甾相液晶形成的液晶层就可精准调制蓝光的出光状态,从而可更好地实现该显示装置的显示控制功能,如此,还无需在显示面板两侧设置偏光片,相对于现有的液晶显示装置取消了偏光片的设计,进而可大幅地提升了显示装置的出光效率。
在本发明的一些实施例中,参考图3,彩膜基板260还可以包括黑矩阵254,且黑矩阵254设置在不同的子像素对应的彩膜层250之间,如此,可有效地避免不同子像素之间的串光问题,从而使显示装置的显示效果更佳。
根据本发明的实施例,形成液晶层230的胆甾相液晶的非寻常光线的折射率(ne)可为1.6、寻常光折射率(no)可为1.4且螺距可为0.3微米,如此,采用上述类型的胆甾相液晶,可更精准地调制波长在400~480nm之间的蓝光的出光效果。在本发明的一些实施例中,形成液晶层230的胆甾相液晶的旋向可以为左旋,如此,采用上述类型的胆甾相液晶对蓝光的调控效果更佳精准。在一些具体示例中,还可在左旋的胆甾相液晶层的上方或下方再设置旋向相反的胆甾相液晶形成的液晶层,即另一层右旋的胆甾相液晶层,如此,左旋的胆甾相液晶层可导出右旋光,而右旋的胆甾相液晶可导出左旋光,从而使液晶层具有偏光效果,进而使显示装置无需偏光片,大幅地提升光效。
具体的,液晶层230层没有加电驱动时,参考图4,特定类型的胆甾相液晶的液晶分子231在不加电驱动的状态下,同层内的液晶分子231呈平行排列,不同层的液晶分子231沿层的法线方向螺旋状排列,如此,不加电状态下的液晶层230(图中未标出)对蓝色背光源100发出的蓝色自然光具有全部反射的调控作用,从而使显示装置呈暗态;然而,对液晶层230层施加合适的电压后,参考图5,由于阵列基板210上的第一电极220与彩膜基板260上的第二电极240之间是垂直电场,会使中间的液晶分子231站立,而破坏了液晶的胆甾相,从而使蓝色背光源100发出的蓝色自然光能透过液晶层230(图中未标出),进而使显示装置呈亮态。
根据本发明的实施例,液晶层230的具体厚度可为1~5微米,如此,采用上述盒厚的液晶层230能对蓝光的反射或透过有更精准的电调控作用。根据本发明的实施例,蓝色背光源100发出的蓝光的中心波长具体可为430~470纳米,如此,针对上述波长范围的蓝光,选择特定类型的胆甾相液晶形成的适宜厚度的液晶层230,可使显示装置的显示功能更精准。
根据本发明的实施例,蓝色子像素B中的蓝色彩膜层251为透明的或蓝色吸收型彩膜,红色子像素R中的红色彩膜层252和绿色子像素G中的绿色彩膜层253分别由量子点材料或蓝色荧光染料形成,如此,蓝色子像素B中的蓝光可直接出射,红色子像素R中的红色彩膜层252可将蓝色光转变成红光再后出射,且绿色子像素G中的绿色彩膜层252可将蓝色光转变成绿光再后出射。在一些具体示例中,蓝色彩膜层251可为蓝色吸收型彩膜,红色彩膜层252和绿色彩膜层253分别由蓝色荧光染料形成,如此,蓝色子像素B中的蓝色光直接穿过蓝色吸收型彩膜后直接出射,红色子像素R中的蓝色光可激发红色彩膜252中的蓝色荧光染料后发射出红光,且绿色子像素G中的蓝光可激发绿色彩膜253中的蓝色荧光染料后发射出绿光。
根据本发明的实施例,红色彩膜层251、蓝色彩膜层252和蓝色彩膜层253的厚度具体可为100~500nm,如此,采用上述厚度的彩膜层250可充分地将蓝色背光源100发出的蓝光转换成其他颜色的光,从而使该显示装置在具有较高的出光效率的同时,还具有丰富的色彩度。根据本发明的实施例,红色彩膜252和绿色彩膜253的具体厚度,本领域技术人员可根据其具体的材料和实际光转化效果进行相应地设计和调整,在此不再赘述。
根据本发明的实施例,该显示装置可以是透明显示装置,且第一电极220和第二电极240可都由氧化铟锡(ITO)形成,如此,采用透明导电的第一电极220和第二电极240可使透明显示装置的透明效果更佳。在本发明的一些实施例中,第一电极220和第二电极240可都为整面结构,且第一电极220和第二电极240的厚度各自独立为50~1500纳米,如此,采用上述厚度的两个电极层,能对液晶层230施加均匀的垂直电场,从而实现液晶层230对蓝光的精准调制。
根据本发明的实施例,该显示装置的具体类型不受特别的限制,具体例如显示屏、电视、手机、平板电脑或智能手表等,本领域技术人员可根据显示装置的实际使用要求进行相应地选择,在此不再赘述。需要说明的是,该显示装置中除了显示面板、蓝色背光源以外,还包括其他必要的组成和结构,以显示屏为例,具体例如外壳、控制电路板或电源线,等等,本领域技术人员可根据该显示装置的功能进行相应地补充,在此不再赘述。
综上所述,根据本发明的实施例,本发明提出了一种显示装置,其由胆甾相液晶形成的液晶层对蓝光的调制效果会比白光更加精准,所以,无需在显示面板的两侧分别设置偏光片,也可实现对显示装置的出光的控制,从而大幅提升显示装置的出光效率。
在本发明的描述中,需要理解的是,术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中,“多个”的含义是至少两个,例如两个,三个等,除非另有明确具体的限定。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中,对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外,在不相互矛盾的情况下,本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例,可以理解的是,上述实施例是示例性的,不能理解为对本发明的限制,本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
