Abstract

本发明涉及显示装置及其反射片,反射片包括基层,铺设于基层之上的反射层,以及铺设在反射层的背向基层的一侧的散射层。由这种反射片穿出的光线更加均匀,从而可提高使用这种反射片的显示装置所显示出的图像的品质。

Description

显示装置及其反射片
技术领域
本发明涉及显示技术领域,特别是涉及一种反射片。本发明还涉及包括这种反射片的显示装置。
背景技术
反射片是用于改变光路的一种光学构件,常用于显示装置内,以对显示装置中的背光源的光路进行改变。
现有技术中的反射片通常只对背光源发出的光进行镜面反射,这使得穿出到反射片之外的光不均匀,从而会导致使用这种反射片的显示装置无法在其显示区域内具有均匀的光,进而使得显示装置显示出的图像亮度不均匀,并且使图像颜色会严重失真。
因此,需要一种出光均匀度较高的反射片。
发明内容
针对上述问题,本发明提出了一种反射片,这种反射片的出光均匀度较高。根据本发明的第一方面,提出了一种反射片,包括基层,铺设于基层之上的反射层,以及铺设在反射层的背向基层的一侧的散射层。
通过使用本发明的反射片,光穿过散射层,然后在反射层处反射,并在反射后穿过散射层而射出到反射片之外。光在穿过散射层时会发生散射,从而能够改变光线的方向,使得光可以朝向多个方向照射。由此在光射出反射片之后,光所覆盖的范围增大,从而提高了反射片的出光均匀度。
在一个实施例中,散射层包括铺设在反射层的背向基层的一侧的量子荧光颗粒。在光照射到量子荧光颗粒后,量子荧光颗粒能受激发而发光,这种受激发而发射的光线朝向四面八方,并由此使得已经受激发而发光的量子荧光颗粒周围的量子荧光颗粒能被该量子荧光颗粒发射出的光线照射到,周围的量子荧光颗粒由此而受到激发而朝向四面八方发射光线。这种结构使得光线能在散射层中均匀散射,从而能保证射出到反射片之外的光的均匀度。
在一个实施例中,散射层包括铺设在反射层的背向基层的一侧的介质体,以及分散在介质体内的多个量子荧光颗粒。量子荧光颗粒能受光照射而发光,由此保证了射出到反射片之外的光的均匀度。另外,介质体能够使分散在其内部的量子荧光颗粒更加均匀,并且方便将量子荧光颗粒覆盖在反射层之上,由此降低了制造工艺难度。
在一个实施例中,多个量子荧光颗粒包括硒化镉量子荧光颗粒。硒化镉量子荧光颗粒的荧光效果较好,能均匀地发出亮度较高的光线,从而能有效提高射出到反射片之外的光的均匀度。另外,硒化镉量子荧光颗粒能发出较为纯正的高品质单色光,由此提高了反射片出射光的品质,从而能有效保证使用这种反射片的显示装置的图像品质。
在一个实施例中,多个所述量子荧光颗粒具有不同的粒径。不同粒径的量子荧光颗粒受背光照射后,能根据粒径大小的不同而发射出颜色不同的光。通过选择合理粒径的量子荧光颗粒进行比例适当的混合,能够使穿过反射片的光混合为优质的白光。
在一个实施例中,在反射层与散射层之间还设置有隔离层。隔离层能将反射层与散射层隔离开。由此在设置散射层时,散射层不会将反射层划伤,从而保证了反射层的反射效果。
在一个实施例中,隔离层与散射层接触的表面的粗糙度大于反射层与隔离层接触的表面的粗糙度。以这种隔离层为基底而铺设散射层,能使得散射层更稳定地固定在隔离层上。
在一个实施例中,反射片还包括覆盖在散射层背向反射层的表面上的保护层。保护层能防止散射层直接暴露在外界,并由此防止了散射层的结构受到破坏。另外,覆盖在散射层上的保护层还能防止保护层氧化,由此保证了散射层的有效性,进而保证了整个反射片的出光均匀度。
在一个实施例中,反射片为平板状反射片。平板状的反射片的加工工艺简单,并由此降低了反射片的加工成本。
根据本发明的第二方面,提出了一种显示装置,其包括上述反射片。使用这种反射片的显示装置所显示出的图像更加清晰,光线均匀,色彩鲜艳,能够满足使用者对图像的需求。
与现有技术相比,本发明的优点在于:(1)光穿过散射层而在反射层处反射,并在反射后穿过散射层而射出到反射片之外。(2)光在穿过散射层时会发生散射,从而能够改变光线的方向,使得光可以朝向多个方向照射。(2)在光射出到反射片之后,光所覆盖的范围增大了,从而有效提高了反射片的出光均匀度。
附图说明
在下文中将基于实施例并参考附图来对本发明进行更详细的描述。其中:
图1显示了本发明的反射片的一个实施例的示意图。
图2显示了本发明的反射片的另一个实施例的示意图。
图3显示了根据图1或图2中的散射层的一个实施例的示意图。
在附图中,相同的部件使用相同的附图标记。附图并未按照实际的比例绘制。
具体实施方式
下面将结合附图对本发明作进一步说明。
图1和图2示意性地显示了本发明的反射片100的大体结构。
反射片100包括基层10以及铺设于基层10之上的反射层30,反射层30能对光线进行反射。优选地在反射层30与基层10之间设置有粘结层20,以将反射层30与基层10粘结在一起,使反射层30能更加稳定地固定在基层10上。反射片100可用于显示装置内,以对显示装置内的背光源所发出的光进行反射,使其朝向所需的方向。
基层10为具有一定支撑能力的结构,其可由聚对苯二甲酸乙二醇酯(PET)制成。
为了保证由反射片100射出的光更加均匀而不局限在特定的方向和位置上,可在反射层30之上再设置相应的散射层50。在光穿过散射层50时,散射层50能改变光路,以使得光能朝向更多的方向发射,进而使得射出到反射片100之外的光能朝向各个方向,有效提高了反射片100的出光均匀度。
在如图1所示的实施例中,散射层50直接设置在反射层30上。这种结构简单并且成本较低。
在如图2所示的实施例中,在散射层50与反射层30之间还设置有隔离层40。在这种结构中,散射层50铺设在隔离层40上而与反射层30相间隔,从而使得散射层50不会划伤反射层30的表面而影响整个反射片100的反射效果。隔离层40可由聚对苯二甲酸乙二醇酯(PET)制成。
另外,还优选地令隔离层40的上表面(即与散射层50相接触的表面)的粗糙度大于反射层30的上表面(即与隔离层40相接触的表面)的粗糙度。与将散射层50直接铺设在反射层30上相比,将散射层50铺设在表面更加粗糙的隔离层40上,使得散射层50不易脱落,从而保证了整个反射片100的结构稳定性。
还可在散射层50之上,即在散射层50背向反射层30的一侧上,铺设保护层60。保护层60附在散射层50的表面上,以防止散射层50的结构受到损坏。优选地,保护层60与隔离层40将散射层50密封式夹在保护层60与隔离层40之间,这还能防止散射层50,尤其是具有量子荧光颗粒52的散射层50发生氧化。保护层60可由硫化锌(ZnS)制成。应理解地是,在图1所示的实施例中,也可相应地设置保护层60。
下面将结合图1到图3对散射层50的结构进行详细描述。
在图1和图2所示的实施例中,散射层50可由组成。在图1所示的实施例中,直接铺设在反射层30上。在图2所示的实施例中,直接铺设在隔离层40上。
优选地,在图1和图2所示的实施例中,散射层50包括介质体51,以及分散在介质体51内的量子荧光颗粒52,如图3所示的那样。在图1所示的实施例中,介质体51直接铺设在反射层30上。在图2所示的实施例中,介质体51直接铺设在隔离层40上。
这种散射层50是将量子荧光颗粒52与介质流体混合,并将混合物涂布在反射层30上而形成的。介质流体可以为水,也可以为甲醇、乙醇等醇类,乙酸乙酯等酯类,卤代烃或甲苯等有机溶剂。
如图3所示的这种散射层50能通过分散在整个介质体51内的量子荧光颗粒52而将穿过反射片100的光均匀化。另外,这种散射层50的制造工艺更为简单,能够方便地运用到生产制造过程中。另外,这种散射层50使得量子荧光颗粒52能够更加均匀地分散在整个介质体51内,有利于使由反射片100射出的光更加均匀。
在反射片100的工作过程中,光进入到散射层50内并照射到量子荧光颗粒52,量子荧光颗粒52受激发而相应地发光。量子荧光颗粒52发出的光是朝向四面八方的,由此改变了光的光路,使得穿过反射片100的光更加均匀。另外,量子荧光颗粒52受激发而发出的光还可以激发在其周围的量子荧光颗粒52,使其一同发光,由此更是提高了穿过反射片100的光的均匀度。这里应理解地是,量子荧光颗粒52即为量子点,是半导体纳米晶体。
在图1和图2所示的实施例中,量子荧光颗粒52均为多个,并且多个量子荧光颗粒52可以由同一种材质的量子荧光颗粒52组成,也能由不同材质的量子荧光颗粒52组成。这种材质混合的量子荧光颗粒52使用更加方便,从而能有效降低反射片100的制造工艺难度以及制造成本。量子荧光颗粒52的材料可为CdS、CdSe、CdTe、ZnSe、InP或InAs等。
另外,可根据背光源的颜色而选择不同的量子荧光颗粒52。量子荧光颗粒52受激发能发出颜色较为纯正的光,因此通过设置与背光源的颜色相匹配的量子荧光颗粒52能够混合出白光,并由此能扩大使用这种反射片100的显示装置的色域,从而能提高显示装置的显示品质。
可选用硒化镉量子荧光颗粒,以发出颜色纯正的高质量单色光。另外,硒化镉量子荧光颗粒还具有较好的荧光效果,能发出均匀并亮度较高的光。此外,通过选择不同粒径的量子荧光颗粒52,可以对发出的光的颜色进行相应的选择。例如,可选择尺寸为10nm的硒化镉量子荧光颗粒,其受激发可以发射较为纯正的高质量红光,选择尺寸为2.5nm的硒化镉量子荧光颗粒,其受激发可以发射较为纯正的高质量绿光,或者选择尺寸为2nm的硒化镉量子荧光颗粒,其受激发可以发射较为纯正的高质量蓝光。
在一个实施例中,可令背光源为蓝色,则可选择受激发发出红光和绿光的量子荧光颗粒,将这两种量子荧光颗粒均匀混合并均匀分散到反射层30之上。受激发产生的红光和绿光与背光源本身的蓝光相混合能形成较为纯正的白光,而应用到显示装置中。
根据需要也可在发出红光和绿光的量子荧光颗粒之中再掺入发出蓝光的量子荧光颗粒,以保证穿出到反射片100之外的光能更好地混合为白光。
由于通过上述散射层50,已经能使得穿过反射片100的光足够均匀了,因此可将反射片100制成平板状,以使反射片100的结构更加简单,并由此降低了反射片100的加工工艺难度和加工成本。
上述反射片100均具有较高的出光均匀度,由此使得使用上述反射片100的显示装置能具有较好的显示品质,所显示的图像亮度均匀,颜色更加真实鲜艳,极大地满足了使用者对图像的需求。
虽然已经参考优选实施例对本发明进行了描述,但在不脱离本发明的范围的情况下,可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是,只要不存在结构冲突,各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例,而是包括落入权利要求的范围内的所有技术方案。
