Description

曲面显示器 技术领域
本发明涉及一种曲面显示器，尤其涉及一种调整背光源的分布密度以改善曲面屏幕的暗区问题的曲面显示器。
 背景技术
随着显示屏幕的尺寸变大，传统的平面屏幕占用的空间也随之变大，使用曲面屏幕可以减少占用空间。此外，曲面屏幕可以显示出环绕画面效果，提供比平面屏幕更佳的显示效果。因此曲面屏幕的应用也越来越广。
然而，使用薄膜晶体管液晶显示器(Thin film transistor liquid crystal display，TFT-LCD)面板作为曲面屏幕仍有缺点需要改善。请参阅图1，图1是曲面屏幕10显示暗区位置的示意图。采用TFT-LCD面板做为曲面屏幕10的制程与制造平板屏幕方法相同，但是后来是将整个模组进行弯曲，形成曲面屏幕10。然而曲面屏幕10在弯折（bending）的区域会出现暗区14。由于弯折后的曲面屏幕10会导致薄膜晶体管基板和彩色滤光基板错位(misalignment)，弯折角度越大的区域，错位也越严重。错位区域导致光线穿透率降低而形成暗区14。一般而言，暗区14亮度只有曲面屏幕10的中间点亮度的60%~80%。
暗区的存在会导致观众看到亮度不均的画面，因此降低曲面屏幕10的显示质量。
 技术问题
因此，本发明主要解决的技术问题是改善曲面屏幕因薄膜晶体管基板和彩色滤光基板错位而形成暗区，导致显示画面亮度不均的技术问题。

 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是曲面屏幕显示暗区位置的示意图。
图2是本发明曲面显示器的示意图。
图3是本发明曲面显示器的剖面图。
图4是本发明第一实施例的背光模块以及液晶显示面板的示意图。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施之特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「顶」、「底」、「水平」、「垂直」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参阅图2和图3，图2是本发明曲面显示器100的示意图，图3是本发明曲面显示器100的剖面图。本发明的曲面显示器100包含液晶显示面板106和背光模块108。液晶显示面板106包含薄膜晶体管基板120、彩色滤光基板122和液晶层126。液晶层126位于薄膜晶体管基板120和彩色滤光基板122之间。彩色滤光基板122包含黑色矩阵层125以及彩色膜层126。液晶显示面板106便是藉由彩色膜层126，来分离出红绿蓝三原色的光，以显示彩色影像。黑色矩阵层125用来避免漏光。薄膜晶体管基板120包含数条数据线102、数条扫描线104和数个像素单元110。每一像素单元110电性连接于一数据线102和一扫描线104。背光模块108包含基板111及多个背光源112，多个背光源112放置在基板111上。多个背光源112可以是发光二极管光源、有机发光二极管光源或是量子点。液晶显示面板106和背光模块108皆呈弯曲状。
液晶显示面板106的驱动方式如下所述：栅极驱动器22输出的扫描信号通过扫描线104输入，使得连接扫描线104的像素单元110接收源极驱动器24输出的数据信号，使像素单元110充电到所需的电压。像素单元110上方的液晶就是依据该数据信号扭转(twist)，进而显示出不同的灰阶。栅极驱动器22会通过数条扫描线104一行接一行地输出扫描信号，再由源极驱动器22对每一行的像素单元110进行充放电。如此依序下去，便可完成液晶显示面板106的完整显示。
请参阅图4，图4是本发明第一实施例的背光模块108以及液晶显示面板106的示意图。液晶显示面板106包含第一显示区151以及第二显示区152。在本实施例中，第一显示区151的曲率大于第二显示区152的曲率。为便于说明，第一显示区151位于液晶显示面板110弯曲角度最大的区域，且第一显示区151大致上呈椭圆型。因为第一显示区151的曲率大于第二显示区152的曲率，所以在同样的背光源112分布密度下，第一显示区151的显示亮度会低于第二显示区152。因此本实施例将多个背光源112的分布密度随着对应的显示区的亮度而调整，使得对应于第一显示区151的多个背光源112的分布密度大于对应于第二显示区152的多个背光源112的分布密度。
因为对应于第一显示区151的多个背光源112的分布密度大于对应于第二显示区152的多个背光源112的分布密度，所以第一显示区151可以获得较高的亮度。在显示时，第一显示区151可以与第二显示区152的显示亮度调整一致，以改善第一显示区151因曲率较大导致暗区的现象。
请参阅图5，图5是本发明第二实施例的背光模块108以及液晶显示面板106的示意图。液晶显示面板106包含中间显示区170、第一显示区171以及第二显示区172。在本实施例中，中间显示区170位于液晶显示面板106的中间，第一显示区171位于中间显示区170和第二显示区172之间，具体来说，第二显示区172是位于液晶显示面板106两侧末端。第一显示区171大致上呈椭圆型。因为液晶显示面板106的弯曲角度由中心向两侧增加，因此在同样的背光源112分布密度下，液晶显示面板106的显示亮度由中心往两侧减小。本实施例将多个背光源112的分布密度随着对应的显示区的亮度而调整，使得对应于第一显示区171的多个背光源112的分布密度小于对应于中间显示区170的多个背光源112的分布密度，大于对应于第二显示区172的多个背光源112的分布密度。也就是说，多个背光源112的分布密度也是随着液晶显示面板106由中心往两侧减小。
因为多个背光源112的分布密度也是随着液晶显示面板106由中心往两侧减小，所以第二显示区172可以获得较高的亮度，第一显示区171次之，中间显示区170获得较低的亮度。在显示时，中间显示区170、第一显示区171与第二显示区172的显示亮度调整一致，以改善第一显示区151因曲率差异导致液晶显示面板106产生暗区的现象。
相较于现有技术，本发明将用于曲面显示器的背光模块上的多个背光源的分布密度随着液晶显示面板的曲率调整，可改善曲面显示器因薄膜晶体管基板和彩色滤光基板错位而形成暗区，导致显示画面亮度不均的技术问题。
综上所述，虽然本发明已以较佳实施例揭露如上，但该较佳实施例并非用以限制本发明，该领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
