Description

曲面显示装置及控制其曲率的方法 技术领域
本申请涉及一种曲面设计方法，特别是涉及一种曲面显示装置及控制其曲率的方法。
背景技术
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，如曲面显示设备。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。反观曲面电视具有弧形设计，因而可减少屏幕边缘的画面失真度，同时提高视觉上的临场感。
就传统的曲面显示设备而言，其作法是将基板整体弯折为具有同一曲率的弧形。然而，采取此一作法会使形成于基板上的外围电路(例如闸极驱动电路)在制造过程中随薄膜晶体管阵列基板弯折形成曲面的形式而承受了弯折应力，连带地使电路特性受到影响。例如电子移动率的下降与临界电压的上升，造成电路驱动能力降低，使得电路信赖性变差。换言之，在显示设备形成具有较佳观赏效果的曲面式时，却牺牲了原有的电路表现。因此，现有曲面显示设备的结构仍有待改进。

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，对依据本申请提出的一种曲面显示装置及控制其曲率的方法其具体实施方式、结构、特征及其功效，详细说明如后。
本申请的显示设备包含一液晶显示面板以及一背光模块，两者相对设置。液晶显示面板主要包含一彩色滤光基板、一薄膜晶体管基板以及一夹设于两基板之间的液晶层，彩色滤光基板及薄膜晶体管基板与液晶层可形成多个阵列配置的画素单元。背光模块可发出光线穿过液晶显示面板，并经由液晶显示面板各画素单元显示色彩而形成一影像。
在一实施例中，本申请的液晶显示面板可为曲面型显示面板，且本申请的显示设备亦可为曲面型显示装置。
曲面显示器(Curved Display)为一种具有弯曲显示面的显示器。在观看曲面显示器时，观赏者的眼睛与曲面显示器的各个位置的距离大概是相等的，且不论是中央区或左右边缘区所显示的画面，观赏者都可以接近直角的视角观看，因此相较于平面显示器，曲面显示器不会产生大视角观看时的亮度偏差与颜色偏差等问题。此外，曲面显示器具有类似立体的视觉效果。因此，曲面显示器已成为受到高度嘱目的显示产品。然而，由于曲面显示器系将平面显示面板以外力弯曲后所形成，因此两片基板之间会而产生相对位置偏差而导致漏光问题，而影响曲面显示器的显示品质。
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，目前越来越多的电视采用曲面方式设计，主要的原因不仅仅在于新颖的外观设计，在电视画质的表现上也有突出的表现，尤其是传统平面液晶显示器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、垂直色差，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，此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两侧到使用者的距离，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的显示画面两侧到用户的距离，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。
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：一可挠性显示器模组510、一曲率调整模块530及一曲率计算单元(图未示)。所述可挠性显示器模组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。所述曲率调整模块530，连接于所述可挠性显示器模组510，用以调整所述可挠性显示器模组510的曲率。所述曲率调整模块530，包括：一齿轮控制单元520，具有一齿轮521；一主旋转轴531及至少一副旋转轴532、533；两个第一曲率调整模块540，枢接于所述主旋转轴531，以形成相对移动的第一活动支架541；以及两个第二曲率调整模块550，枢接于所述副旋转轴532、533，并啮接所述齿轮521，以配合所述齿轮521控制而形成相对移动的第二活动支架551。所述曲率计算单元，用于感测一物体因而产生一曲率控制讯号，来控制所述曲率调整模块530，以调整所述可挠性显示器模组510曲率。
