Description

可调整曲率的曲面显示装置 技术领域
本申请涉及一种曲面显示装置的控制方法，特别是涉及一种可调整曲率的曲面显示装置。
背景技术
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其新颖的外观设计，在电视画质的表现上也有突出的表现，尤其是传统平面LCD(不论是VA型LCD，或是IPS型LCD)电视在大视角的观看上，普遍存在与中心视角一定的色差，使得画面质量随着视角越大，质量越差。
传统平面LCD改善视角的方式，是通过将一个画素，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以及子画素B的gamma曲线，来补偿改善侧视角的色差，这种补偿方法叫做空间画素补偿方法。
此外，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，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。在适当的曲率以及观测距离下，显示器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问题。
传统上曲面显示器是针对单一观测者在on-axis坐标位置(即中心位置)进行设计，但是在观赏电视时，通常不一定只有一个观测者，且也不一定在中心位置观测。因此曲面电视最佳视角的条件很容易因为观测者的位置不同，而无法获得最佳的画质。
发明内容

首先参阅图1及图3，本申请可调整曲面显示器曲率的控制方法，流程包括：流程S100，利用安装在曲面显示器10上的影像传感器20撷取场景画面信息21，在本申请的一实施例中，所述场景画面信息21为所述影像传感器20用以撷取观赏者30所在的空间的信息。
在本申请的一实施例中，在可撷取场景画面信息21为前提之下，所述影像传感器20可为多个影像传感器，可分别设置于所述曲面显示器10上的任意位置。
在本申请的一实施例中，所述的影像传感器20在以可撷取场景画面信息21为前提之下，可包括广角镜头。
接着流程S110，请同时参阅图1及图2，通过处理单元40计算所述场景画面信息21中观赏者30的位置；在本申请的一实施例中，处理单元40包括人脸辨识系统，用以辨识所述场景画面信息21中的观赏者30的人脸以确认观赏者30数量。
在本申请的一实施例中，请参阅图4，所述位置为观赏者30与所述曲面显示器10中心线101之间的距离X1、X2以及观赏者30与曲面显示器10之间的直线距离D，所述直线距离D平行于所述中心线101。
接着流程S120，请同时参阅图1及图4，通过所述位置计算出观赏者30与所述曲面显示器10中心线101的角度，若以中心线101为基准，观赏者30位于所述曲面显示器10中心线101左方的距离为X1，观赏者30与曲面显示器10之间的直线距离为D，则所述角度θL为arctan(-X1/D)，θL角度介于0度至-90度之间，若观赏者30位于所述曲面显示器10中心线101右方的距离为X2，观赏者30与曲面显示器10之间的直线距离为D，则所述角度θR为arctan(X2/D)，θR角度介于0度至90度之间。
接着流程S130，通过所述角度θL及θR计算出最佳视角信息为θeff=(θL+θR)/2。
在本申请的一实施例中，所述最佳视角信息为θeff=(θL+θR)/2可等于一公式为
Figure PCTCN2017082363-appb-000002
其中n可表示为观赏者30数量。
接着流程S140，通过所述最佳视角信息θeff来取得一最佳曲率，以控制所述曲面显示器的一显示面弯折距离。在本申请的一实施例中，可例如利用查表1完成，此查表1例如可储存于处理单元40内：
Figure PCTCN2017082363-appb-000003
表1
在本申请的一实施例中，根据表1，所述θeff介于0度至90度之间，所述最佳曲率例如介于1500R至平面，例如介于1500R～5500R，所述显示面弯折距离例如为0mm～200mm，例如为30mm～100mm。
根据本申请所述曲面显示装置，本申请的曲面显示装置可例如为一种曲面电视。本申请的曲面显示装置可包括软件或对应程序，以执行上述的可调整曲面显示装置曲率的控制方法，所述方法包括：利用安装在一曲面显示器上的一影像传感器撷取一场景画面信息；通过一处理单元计算所述场景画面信息中一观赏者的一位置；通过所述位置计算出观赏者与所述曲面显示器中心线的一角度；通过所述角度计算出一最佳视角信息，通过所述最佳视角信息来取得一最佳曲率，以控制所述曲面显示器的一显示面弯折距离。
在本申请的实施例中，如图5所示，曲面显示装置可更包括曲率控制机构50，其电性连接于处理单元40，用以依据处理单元40的控制信息来弯折曲面显示器10，以改变曲面显示器10的曲率。
本申请通过影像传感器装置，以及处理单元分析，设计出一智能型自动控制显示器曲率的方法，不但较传统固定曲率的电视更加弹性，也更贴近实际观赏者的应用情况，大幅改善观赏者在不同视角的画面质量。
“在一些实施例中”及“在各种实施例中”等用语被重复地使用。所述用语通常不是指相同的实施例；但它亦可以是指相同的实施例。“包含”、“具有”及“包括”等用词是同义词，除非其前后文意显示出其它意思。
以上所述，仅是本申请的较佳实施例而已，并非对本申请作任何形式上的限制，虽然本申请已以较佳实施例揭露如上，然而并非用以限定本申请，任何熟悉本专业的技术人员，在不脱离本申请技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
