Description

显示装置 技术领域
本申请涉及一种显示装置，特别是涉及一种可对应用户的眼睛位置来转动的平面或曲面显示装置。
背景技术
近年来，随着科技的进步，许多不同的显示设备，例如液晶显示器(Liquid Crystal Display，LCD)或电激发光(Electro Luminenscence，EL)显示设备已广泛地应用于平面显示器。以液晶显示器为例，液晶显示器大部分为背光型液晶显示器，其是由液晶显示面板及背光模块(Backlight Module)所组成。液晶显示面板是由两片透明基板以及被封于基板之间的液晶所构成。
随着显示技术的发展，除了尺寸与画质上的改良外，在显示设备的外观上亦有所改变，像是曲面显示设备。相较于平面式的显示设备，曲面显示设备不仅可在同样宽度下制成更大的尺寸，曲面显示设备还可提供较好的观赏效果。以平面电视和曲面电视为例，观赏者视线自正对平面电视屏幕中心朝两外侧移动时，往往会发现平面电视边缘部份的视觉感受较差。尤其是传统平面液晶显示器(不论是垂直配向(Vertical Alignment，VA)型，或是平面转换(In-Plane Switching，IPS)型)电视在大视角的观看上普遍存在与中心视角一定的色差，使得画面品质随着视角越大，品质越差。

为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出一种显示装置，其具体实施方式、结构、特征及其功效，详细说明如后。在一些实施例中，本申请的显示面板可为平面型显示面板，亦即没有弯曲的显示面板。
在一些实施例中，本申请的显示面板可以应用于各种不同的显示器上，例如：液晶显示器(Liquid Crystal Display；LCD)、有机电致发光显示器(Organic Electro Luminescence Display；OEL)、有机发光二极管显示器(Organic Light Emission Diode Display；OLED)、发光二极管显示器(Light Emission Diode Display；LED)、电浆显示面板(Plasma Display Panel；PDP)、场放射显示器(Field Emission Display)、纳米炭管显示器、电子墨水(E-ink)显示器、干涉调控显示器(Interferometric Modulator Displays)、使用时序多任务光学快门(Time Multiplexed Optical Shutter，TMOS)技术的微机电显示器或使用电致变色显示(Electrochromic Display，ECD)技术的显示器等。
图1a为范例性电视视角示意图及图1b为范例性垂直与水平色差示意图。请参照图1a及图1b，平面液晶显示器100不论是垂直配向(Vertical Alignment，VA)型，或是平面转换(In-Plane Switching，IPS)型电视在大视角的观看上普遍存在与中心视角的法向角度102及中心视角的水平角度104有一定的水平色差120、垂直色差122，使得画面品质随着视角越大，品质越差。
图2a为范例性画素gamma曲线示意图及图2b为范例性利用电压控制画素gamma曲线示意图。请参照图2a及图2b，传统上平面液晶显示器改善视角的方式，是藉由将一个画素，分割成两个子画素，即为子画素A以及子画素B，并利用电压控制子画素A的gamma曲线222以及子画素B的gamma曲线224，将子画素A的gamma曲线222以及子画素B的gamma曲线224合并成gamma曲线230，区别于传统gamma曲线220，以接近理想的gamma曲线210，因而来补偿改善侧视角的色差，这方法称为空间画素的补偿方法。
图3为范例性用户300观看显示器310不同视角与跟显示器310不同距离关系示意图。请参照图3，在用户观看平面显示器时，平面显示器的显示画面中央到用户的距离不等于显示画面的二侧到使用者的距离，从而造成用户观看到的影像失真。因此，有人提出曲面显示器310。使用者300观看曲面显示器310时，由于曲面显示器310的显示画面中央到用户300的距离接近曲面显示器310的显示画面二侧到用户的距离，因此用户300观看到的影像可更加拟真，并同时减少观看疲劳感。因此，另一种改善视角画质的方法是采用曲面显示器的设计方式，即针对设定好的观测距离D1、D2、D3，计算出相对应的显示器曲率，一般而言显示器的曲率为R2000左右，电视机则设计在R4000左右。示意图如图3所示，可以看出在适当的曲率以及观测距离D1、D2、D3下，显示器310的各个视角与中心正视角是一致的，因而改善屏幕因不同视角而造成的画质劣化。值得说明的是，以下说明是以曲面显示器为例，但不限于曲面显示器或曲面显示面板，本申请的显示装置也可以是平面型显示装置。
图4为另一范例性用户401、402、403观看显示器405不同视角与跟显示器405不同距离关系示意图。请参照图4，传统上曲面显示器405是针对单一观测者402在中心轴的坐标位置(即中心位置)进行设计，但是在观赏电视405时，通常不一定会只有一个观测者401、402、403，且也不一定会在中心位置观测，如图4所示。因此曲面电视405最佳视角410、420的条件很容易随着观测者401、402、403的位置不同，而无法获得最佳的画质。
图5为本申请一实施例的曲面显示装置500示意图。请参照图5，在本申请的一实施例中，一种曲面显示装置500，包括：一显示面板510及一角度调整模组540。所述显示面板510，包括：一盖板511，具有第一曲面512；以及一背板515，与所述盖板511相对设置，具有第二曲面516；以及一液晶显示面板513，设置所述背板515及所述盖板511之间。所述角度调整模组540，连接于所 述显示面板510，用以调整所述显示面板510的旋转角度，包括：一旋转控制机构单元520，具有一齿轮521；以及一马达控制单元530，具有一马达531，所述马达531连接所述齿轮521。
在一实施例中，本申请所述马达531为一步进马达。

在一实施例中，本申请所述用户位置信息侦测单元502包括一旋转角度计算组件，用以自动分析出使用者701、702所偏移显示器中心平面的角度位置θ，tan(θ)＝d2/d。
在一实施例中，本申请所述用户位置信息侦测单元502更包括一讯号处理器，分析用户701、702偏离显示器中心的距离d2。
在一实施例中，本申请所述用户位置信息侦测单元502可以预载一显示器平面505与使用者701的预设距离d，以及一显示器平面505与使用者702的距离d1。
在一实施例中，本申请所述马达531为一步进马达。
在一实施例中，本申请所述用户位置信息侦测单元502可为一感测芯片或传感器。
请参照图6及图8，在本申请的一实施例中，一种智能型控制显示装置500旋转角度的方法，包括以下流程：提供所述的显示装置500；S610：依据所述用户位置信息侦测单元502感测一物体影像的位置信息，产生一控制讯号；S620：依据所述控制讯号计算旋转角度；S630：控制所述马达控制单元530的马达531转动；以及S640：同时藉由所述旋转机构单元520控制所述可挠性显示器模组510的旋转角度。
理解的是，在一些实施例中，上述方法可通过处理器在计算装置中被实现，例如通过运行应用程序。但是应当强调的是，除非另有说明，上述方法不需要按照如图所示的确切顺序被执行；并且类似的多个流程(blocks)可以并行地被执行，而不是按顺序；因此上述方法的元素在文中称为"流程(blocks)"而不是"步骤"。还应当理解的是，上述方法也可以在计算装置的变型上被实现。
可以进一步理解，本申请的方法能在显示装置中实现。然而，本申请的方法还可以在与显示装 置有相似部件、但设置在不同配置中的相似装置或系统中被实现。
在一实施例中，本申请所述的方法，在同时藉由所述旋转控制机构单元520的转动程度，控制所述显示面板510的旋转角度的步骤包括：利用所述旋转控制机构单元520连接所述显示面板510的背板515；在藉由所述齿轮521的转动因而调整所述背板515的第二曲面516；进行第二曲面516的旋转角度调整而造成所述盖板511的第一曲面512的旋转角度跟着调整。
在一实施例中，本申请所述的方法，所述马达531为一步进马达。
在一实施例中，本申请所述的方法，所述曲率计算单元502可为一感测芯片或传感器。
图9为本申请一实施例的旋转控制机构单元520的作动示意图，图10为本申请一实施例的显示装置500作动示意图，图11为本申请一实施例的平面显示面板610示意图。请参照图7、图8、图9及图10，在本申请的一实施例中，一种显示装置500，包括：一显示面板510、610及一角度调整模组540。所述显示面板510，包括：一盖板511，具有第一曲面512；以及一背板515，与所述盖板511相对设置，具有第二曲面516；以及一液晶显示面板513，设置所述背板515及所述盖板511之间。所述角度调整模组540，连接于所述显示面板510，用以调整所述显示面板510的旋转角度，包括：一旋转控制机构单元520，具有一齿轮521；一马达控制单元530，具有一马达531，所述马达531连接所述齿轮521；以及一用户位置信息侦测单元502，具有一电荷耦合组件505，电性耦接所述马达控制单元530，用以感测一用户的眼睛位置信息。
如图11所示，用户位置信息侦测单元502可通过感测一用户影像来感测用户眼睛5011的位置，以取得用户501的眼睛位置信息。因此，用户位置信息侦测单元502可更精确地取得用户位置信息。在一实施例中，本申请所述用户位置信息侦测单元502包括一旋转角度计算组件，透过传输界面，电性连接所述马达控制单元530，控制马达531所需要的旋转角度θ。
在一实施例中，本申请所述马达控制单元530在接受旋转角度计算组件所提供的角度信息后，将所述角度信息转化成一相对旋转物理量S(r×θ)(旋转物理量＝齿轮半径×使用者所偏移显示器中心平面的角度位置)，并依据所述相对旋转物理量来控制马达53。
