Description

显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种显示装置。
 背景技术
随着电子技术的发展，诸如智能手机等显示装置的智能化程度越来越高。显示装置可以通过其显示面板显示画面。
显示技术发展日新月异，液晶显示模组（Liquid Crystal Module，LCM）逐渐取代阴极射线显像管（Cathode Ray Tube，CRT）技术，广泛应用于手机、平板、TV、车载及可穿戴设备等领域。更进一步，3D（three-dimensional）显示技术搭载LCM近年来备受关注，其显示效果更为立体逼真。
传统的3D显示技术大多采用红蓝分屏或偏振技术通过佩戴3D眼镜显示立体效果，这种特制眼镜配套设备限制了3D显示的使用场地，造成观看不便且不利于3D显示的推广。
 技术问题
近年来搭载光栅的裸眼3D显示成为焦点，此技术不需要佩戴眼镜，直接肉眼观看即可获得3D立体效果，但目前的裸眼3D显示装置在3D显示效果方面还存在很多不足。
 技术解决方案

本申请实施例提供一种显示装置，包括显示模组，所述显示模组包括显示面板、裸眼3D光栅以及反棱镜片，所述反棱镜片设置于所述显示面板与所述裸眼3D光栅之间；所述反棱镜片包括基材以及设于所述基材一侧的棱镜层，所述棱镜层朝向所述显示面板设置。
 有益效果
本申请实施例提供的显示装置，通过在显示面板与裸眼3D光栅之间设置反棱镜片，能够将背光发出通过显示面板的光线发散后进入裸眼3D光栅中以增强立体光学效果。

 本发明的实施方式
请参阅图1，本申请实施例提供一种显示装置，包括依次层叠设置的背光模组300、显示模组200以及盖板100。该显示装置可以为裸眼3D显示装置（如图2所示），也可以为非3D显示装置。下面以裸眼3D显示装置为例进行说明。
相关技术中，裸眼3D显示装置的立体显示效果不足以满足目前用户的需求。基于此考虑将本申请实施例的裸眼3D显示装置中的盖板100、显示模组200及背光模组300三者中的至少一者设计为可以改善立体显示，提升立体显示效果，下面逐个进行说明。
请参阅图3、图4或图5，同时参阅图2，本申请实施例提供一种盖板100，盖板100设置于显示模组200的出光侧，盖板100的表面具有网点区域与非网点区域15，网点区域设于非网点区域15的外围，网点区域内设有间隔设置的多个凹槽。具体的，网点区域可以设置于非网点区域15的1侧、2侧、3侧或4侧，盖板100可用于盖设在普通的显示模组或者具有裸眼3D显示功能的显示模组上，当盖板100用于盖设在具有裸眼3D显示功能的显示模组上时，可以使网点区域对应于显示模组的边缘设置，这样网点区域内的凹槽101能够对从显示模组发出并进入盖板100内的光线进行漫反射，提高显示模组边缘的光线扩散角度，进而提高裸眼3D显示的可视角度和立体显示效果。
如图3所示，在一些实施例中，网点区域包括第一区域11和第二区域12，第一区域11和第二区域12分别设于非网点区域15的相对两侧。当应用于裸眼3D显示装置中时，第一区域11和第二区域12可以分别对应于显示装置的左右两侧设置，当观众从显示装置左右两侧的位置观看时，由于第一区域11和第二区域12的光扩散效果提高了显示装置左右两侧的可视角度，因此可以提高从左右两侧（斜视）显示装置时的立体显示效果。
如图4所示，在另一些实施例中，网点区域包括沿非网点区域15外围依次设置的第一区域11、第三区域13、第二区域12，第一区域11和第二区域12相对设置，第三区域13设于第一区域11和第二区域12之间，并且第三区域13的两端分别与第一区域11和第二区域12连接。当应用于裸眼3D显示装置中时，第一区域11和第二区域12可以分别对应于显示装置的左右两侧，第三区域13可以对应于显示装置的下侧，当观众从显示装置的左侧、右侧或下侧进行观看时，由于第一区域11和第二区域12的光扩散效果可以提高显示装置左右两侧的可视角度，第三区域13的光扩散效果可以提高显示装置下侧的可视角度，因此可以提高从左侧（斜视）、右侧（斜视）或下侧（仰视）观看显示装置时的立体显示效果。
如图5所示，在另一些实施例中，网点区域包括沿非网点区域15外围依次设置的第一区域11、第三区域13、第二区域12、第四区域14，第一区域11和第二区域12相对设置，第三区域13和第四区域14相对设置，第一区域11、第三区域13、第二区域12、第四区域14依次首尾连接，形成闭环。当应用于裸眼3D显示装置中时，第一区域11和第二区域12可以分别对应于显示装置的左右两侧，第三区域13和第四区域14可以分别对应于显示装置的下侧和上侧，当观众从显示装置的左侧、右侧、下侧或上侧进行观看时，由于第一区域11、第二区域12、第三区域13、第四区域14的光扩散效果可以分别提高显示装置左侧、右侧、下侧、上侧的可视角度，因此可以提高从左侧（斜视）、右侧（斜视）、下侧（仰视）或上侧（俯视）观看显示装置时的立体显示效果。
本申请实施例中，设置于网点区域内的凹槽101的尺寸可以设置为从非网点区域15向盖板100边缘的方向保持一致、逐渐增大或逐渐减小，设置于网点区域内的凹槽101的分布密度可以设置为从非网点区域15向盖板100边缘的方向保持一致、逐渐增大或逐渐减小。需要说明的是，当设置于网点区域内的凹槽101的尺寸从非网点区域15向盖板100边缘的方向逐渐减小，并且设置于网点区域内的凹槽101的分布密度从非网点区域15向盖板100边缘的方向逐渐增大时，网点区域的漫反射效果从非网点区域15向盖板100边缘的方向逐渐增强，从而显著提升了裸眼3D显示装置边缘区域的可视角度和立体显示效果。
本申请实施例中，设置于网点区域内的凹槽101的形状可以设置为半圆球形、半椭球形、长方体形、正方体形、不规则形等各种形状，需要说明的是，当设置于网点区域内的凹槽101的形状均为半圆球形时，相对于其它形状来说，半圆球形的凹槽101能够实现更好的光扩散效果，从而实现更好的3D显示效果。
在一些实施例中，网点区域的面积小于非网点区域15的面积。
本申请实施例提供的盖板100可应用于手机、平板电脑、电视机、电脑显示器、车载显示装置、笔记本电脑、可穿戴智能设备等显示装置中。
在一些实施例中，盖板100上设有凹槽101一侧的表面边缘还可以涂设遮光油墨，遮光油墨所在的区域用于形成显示装置的非显示区域（边框），遮光油墨内侧的区域形成显示装置的显示区域。网点区域位于显示区域与非显示区域的交接处，即网点区域的一部分位于非显示区域中，另一部分位于显示区域中。
上面介绍了通过对改进盖板100的结构来改善裸眼3D显示装置的3D显示效果，下面介绍如何通过改进显示模组200来改善裸眼3D显示装置的3D显示效果。

在一些实施例中，棱镜层32的棱镜角度α为90°。
具体的，基材31的材料为透明材料，例如PET（Polyethylene terephthalate，聚对苯二甲酸乙二醇酯）等透明有机材料。
如图7所示，在一些实施例中，反棱镜片30’还包括设于基材31远离棱镜层32一侧的雾度层33，雾度层33朝向裸眼3D光栅20设置。该反棱镜片30’中，棱镜层32起到对入射的光线进行发散的作用，雾度层33起到对发散后的光线进行均匀化的作用，通过棱镜层32与雾度层33的配合实现更好的光扩散效果，进而使裸眼3D显示装置呈现更好的立体显示效果。
在一些实施例中，雾度层33的表面具有凹凸不平的微结构。
请参阅图2，在一些实施例中，显示面板40与裸眼3D光栅20之间还设有限位件53，限位件53设于反棱镜片30的外围，以限制反棱镜片30的移动，避免反棱镜片30从显示装置中脱落，提升显示装置的结构稳定性。
在一些实施例中，限位件53为泡棉，不仅可以对反棱镜片30起到限位作用，在显示装置受到外力挤压时还能够起到缓冲作用，提升显示装置的结构稳定性。
请参阅图2，在一些实施例中，显示面板40包括TFT（Thin Film Transistor，薄膜晶体管）基板41、设置于TFT基板41上方的CF（Color filter，彩色滤光片）基板42、设置于TFT基板41与CF基板42之间的液晶层；另外，CF基板42上方设置有上偏光片51，TFT基板41下方设置有下偏光片52，上偏光片51与下偏光片52共同实现偏光效果。反棱镜片30设置于上偏光片51和裸眼3D光栅20之间，增强光学3D效果。CF基板42的边缘上方设有限位件53，限位件53设于反棱镜片30的外围，对反棱镜片30起到限位作用，避免反棱镜片30从显示装置中脱落，提升显示装置的结构稳定性。本实施例中，限位件53为泡棉，不仅可以对反棱镜片30起到限位作用，在显示装置受到外力挤压时还能够起到缓冲作用，提升显示装置的结构稳定性。
上述显示模组200可应用于手机、平板电脑、电视机、电脑显示器、车载显示装置、笔记本电脑、可穿戴智能设备等显示装置中。
上面分别介绍了通过改进盖板100和显示模组200的结构来改善裸眼3D显示装置的3D显示效果，下面介绍如何通过改进背光模组300的结构来改善裸眼3D显示装置的3D显示效果。
