Description

可调整曲面显示器曲率的控制方法及曲面显示装置 技术领域
本申请涉及一种曲面显示器的控制方法，特别是涉及一种可调整曲面显示器曲率的控制方法及曲面显示装置。
背景技术
就已知技艺LED曲面并非原始曲面屏幕，而是通过物理特性的改变将平面变弯，改变了平板的物理属性。LED由很多零部件组成，当屏幕变成曲面时，这些零部件并不能跟着变成弯曲状，这也是LED曲面电视机身较厚、甚至背部依旧采用平面设计的主要原因。由于LED屏本身的柔韧性较差，所以在物理弯曲中存在着较大的技术缺陷。
目前曲面屏幕只有在大屏条件下才能体现出视觉优势，形成环绕式的观赏体验。所以，如果一款平板电视的尺寸是55英寸，那么曲面电视至少需要65英寸才能达到相似的效果。
曲面电视强调弯曲的屏幕更适合视觉原理，而其实这种视觉效果体现在需坐在电视中心点位置。也就是说，如坐在其他位置观看，非但不能达到理想视觉效果，反而因为屏幕的弯曲，使得画面产生扭曲效应。而事实上，家庭收看电视，不可能多人挤在电视中心点。
而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具有一定的色差，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
为了解决上述技术问题，本申请的目的在于，提供一种曲面显示器的控制方法，特别是涉及一种可调整曲面显示器曲率的控制方法，自动调整显示器的显示面曲率，使其符合一个观赏者至多个观赏者在不同位置的最佳曲率。
本申请的目的及解决其技术问题是采用以下技术方案来实现的。依据本申请提出的一种可调整曲面显示器曲率的控制方法，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。
本申请的另一目的为提供一种曲面显示装置，包括：一影像传感器，用以撷取一场景画面信息；一处理单元，连接于所述影像传感器，用以计算所述场景画面信息中一观赏者的一位置；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；所述角度计算出一最佳视角信息；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装置的一显示面弯折距离。
本申请的目的及解决其技术问题还可采用以下技术措施进一步实现。
在本申请的一实施例中，所述场景画面信息为所述影像传感器用以撷取观赏者所在空间的信息。
在本申请的一实施例中，所述影像传感器为多个影像传感器。
在本申请的一实施例中，所述影像传感器包括广角镜头。
在本申请的一实施例中，所述处理单元包括人脸辨识系统，用以辨识所述场景画面信息中的观赏者数量。
在本申请的一实施例中，所述位置为观赏者与所述曲面显示器中心线之间的距离以及观赏者与所述曲面显示器之间的直线距离。
在本申请的一实施例中，观赏者位于所述曲面显示器中心线左方的距离为X1，观赏者与曲面显示器之间的直线距离为D，则所述角度θL为arctan(-X1/D)，若观赏者位于所述曲面显示器中心线右方的距离为X2，观赏者与所述曲面显示器之间的直线距离为D，则所述角度θR为arctan(X2/D)，则所述最佳视角信息为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 PCTCN2017078126-appb-000001
其中n为观赏者数量。
在本申请的一实施例中，所述θeff介于0度至90度之间，所述最佳曲率为4000R至平面，所述显示面弯折距离为50mm至0mm。
在本申请的一实施例中，所述曲面显示装置还包括软件或对应程序，以执行所述的可调整曲面显示器曲率的控制方法。
有益效果
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。
