Description

一种显示屏幕
本申请要求在2015年8月10日提交中国专利局、申请号为201510487881.9、发明名称为“一种显示屏幕”以及申请号为201520599458.3、发明创造名称为“一种显示屏幕”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示领域，尤其涉及一种显示屏幕。
背景技术
本部分旨在为权利要求书中陈述的本申请的实施方式提供背景或上下文。此处的描述不因为包括在本部分中就承认是现有技术。
人类信息传播科技的发展趋势,是不断降低信息熵值，最终使信息熵值趋近于零，也就是尽量逼真复现真实世界。自电影出现以后，显示屏幕就在不断变革、进步、更新。
按照屏幕的形状划分，现有技术的显示屏幕大致可分为：平面幕、环幕和球幕。《高临场感显示》(ISBN：7030110218，(日)谷千束)中提出，高临场感形成的几个要素是：高清晰度、全彩色、立体、无边界。其中，所述无边界是指普通观众在正常视域范围内看不到显示装置上显示的画面与现实世界之间的交界处，也就是看不到显示屏幕的边界，使得观众有较强的沉浸感。平面幕、环幕和球幕均可以很好的做到高清晰度、全彩色和立体的效果，但是由于在实际应用中，平面幕和环幕不可能做到无限大，而且不能包裹观众，因此平面幕和环幕无法做到无边界。而球幕可以很好的将观众包裹其中，观众在正常的可视范围内看不到显示屏幕的边界，因此只有球幕可以做到无边界，实现观众沉浸感较强的目的。
目前有很多关于球幕技术的专利文献，例如美国专利US8054547B2(授权日为2011年11月8日)公开了一种无缝、无阴影、背面投影的 穹顶显示系统，该系统包括一个由多个半透明屏幕拼接而成的360度显示屏幕，拼接后的显示屏幕呈穹顶状，即部分球幕的形状。这种显示屏幕搭建起来非常复杂，需要较高的经济、时间和人力成本。
再例如，美国专利US8992336B2(授权日为2015年3月31日)公开了一种影院结构，该影院中包括一个穹顶状的屏幕，即部分球幕，该屏幕可以包括球冠，也可以不包括球冠，所述圆顶状的屏幕环绕在观众座椅周围。
背景技术中提到的球幕，包括专利文献中的球幕，虽然具有使观众沉浸感较强的优点，但是在实际应用中，由于观众的座椅是成排排列的，坐在距离中间位置较远的两边观众，水平观看时看到的球幕倾斜度较高，不符合人眼正常的观看角度，造成观看不舒适的感觉。而如果要保证靠边的观众也能看着舒服，则需要球幕有较大的直径，因此制造球幕的成本较高。
发明内容
为了解决该技术问题之一，本申请提供了一种显示屏幕，在满足观众沉浸感较强的基础上，实现观众观看舒适的目的，且占用更小的安装空间。
本申请实施例提供了一种显示屏幕，所述显示屏幕呈全封闭或部分封闭的壳体结构，所述壳体结构的内部用以在水平方向上提供180度至360度视角的连续图像；所述壳体结构包括筒状部，所述筒状部的侧壁在轴向截面上呈平滑的弧线设置或呈直线设置，当呈弧线设置时，所述弧线对应的圆的半径大于所述弧线距离所述轴线的最大垂直距离。
在本申请一实施例中，所述筒状部的横截面包括圆形、椭圆形、不对称圆形或带圆角的四边形。
在本申请一实施例中，当所述筒状部的横截面为带圆角的四边形时，所述四边形为矩形。
在本申请一实施例中，所述壳体结构还包括一个或两个端部；
当所述壳体结构包括一个端部时，所述一个端部与所述筒状部的一端采用平滑过渡的方式连接；
当所述壳体结构包括两个端部时，所述两个端部分别与所述筒状部的两端采用平滑过渡的方式连接。
在本申请一实施例中，所述筒状部和所述端部为一体式或可拆卸式。
在本申请一实施例中，当所述筒状部的侧壁在轴向截面上呈直线设置，且所述筒状部的横截面为圆形时，所述端部为半圆球状结构。
在本申请一实施例中，所述壳体结构为椭球体结构。
在本申请一实施例中，所述椭球体结构的横截面为圆形或椭圆形。
在本申请一实施例中，所述显示屏幕包括自发光显示屏幕或投影显示屏幕。
在本申请一实施例中，所述显示屏幕用于显示平面影像或立体影像。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
目前的显示屏幕包括平面幕、环幕和球幕，其中，平面幕是指屏幕是平面的，通常为矩形；环幕是指呈具有一定高度的圆环状的屏幕；球幕是指呈标准圆球状的屏幕。在实际应用中，基于成本的考虑，平面幕的长和宽以及环幕的高度不可能做的无限大，因此观众可以看到屏幕显示画面与现实世界的边界。而球幕可以将观众全封闭或部分封闭起来，因而观众在视域范围内看不到球幕上显示的画面与现实世界的边界，仿佛置身于球幕播放画面呈现的世界中，使得观众有非常强烈的沉浸感。
然而，发明人发现，通常情况下，观众的座椅是成排设置的，而且座椅的中央位置一般靠近或位于球幕的球心处，坐在中央位置的观众，水平观看时看到的球幕是对称的，因此观看舒适度最高，而对于坐在距离中央位置较远的观众，水平观看球幕时看到的屏幕倾斜度较大，因此观看舒适度较低。如果要保证这些距离中央位置较远的观众的观看舒适度，那么球幕的直径就需要足够长，因此工程成本往往较高。
为了解决上述技术问题，本申请实施例提供了一种显示屏幕，所述显示屏幕呈全封闭或部分封闭的壳体结构，所述壳体结构的内部用以在水平方向上提供180度至360度视角的连续图像。
所述壳体结构包括筒状部，所述筒状部的侧壁在轴向截面上呈平滑的弧线设置或呈直线设置，当呈弧线设置时，所述弧线对应的圆的半径大于所述弧线距离所述轴线的最大垂直距离。
下面阐述一下本实施例技术方案的基本原理：
参见图1，该图为本实施例中筒状部轴向截面的示意图。虚线xx’为所述筒状部的轴线，所述筒状部的侧壁在轴向截面上呈平滑的弧线设置，且所述弧线对应的圆(实线圆)的圆心为点O，半径为R。所述弧线距离所述轴线xx’的最大距离为h。
图1中以点n为圆心、所述h为半径形成的虚线圆表示球幕的轴向截面。当观众(以小黑三角形表示)朝向水平正前方(箭头所指方向)观看屏幕时，在所述h一定的情况下，由于本实施例中，所述筒状部的弧线对应的圆的半径R大于所述h，因此所述弧线的弧度要小于以h为半径的球幕的弧线的弧度，所以提高了观众眼睛观看屏幕的舒适度，尤其对于远离中央位置的观众。
若要球幕的弧度与筒状部的弧度相同，保证观众眼睛观看的舒适度，则需要构建一个半径为R的球幕(以实线圆表示)，从图中可以看出，所述半径为R的圆的面积要大于所述筒状部的截面的面积，因此，如果是半径为R的球幕，所述筒状部的体积完全有可能小于所述球幕的体积，在这种情况下，本实施例提供的显示屏幕还有效节约了制造成本。
所述图1描绘了本实施例中筒状部侧壁在轴线截面上呈弧线设置的情况，在实际应用中，所述筒状部侧壁在轴线截面上还可以呈直线设置，此时，在同一轴向截面上，所述筒状部侧壁的所有点到所述筒状部轴线的距离是相等的，也就是说，对于同一排观众，他们朝向正前方观看屏幕的舒适度是一样的，在水平方向上都达到了最大舒适度。但是这种舒适度球幕却无法实现，因为如果要保证球幕的弧度近似直线的弧度，那么需要球幕的直径无限大，这在实际应用中是无法做到的。相对于无限大体积的球幕，本实施例提供的显示屏幕的体积相对小很多，达到节约的制造成本的目的。
在本实施例中所述显示屏幕为壳体结构，所述壳体结构可以是全封闭式，也可以是半封闭式。下面首先介绍几个全封闭式的显示屏幕实施例。当所述壳体结构为全封闭式时，所述壳体结构包括用于封闭所述筒状部的两个端部，所述两个端部与所述筒状部采用平滑过渡的方式连接。所述端部与所述筒状部可以是一体式，也可以是可拆卸式。
在全封闭式显示屏幕的实施例中，首先介绍在筒状部侧壁在轴线截面上呈直线设置的各个实施例。
在一个实施例中，参见图2，图2(a)为显示屏幕的正视图(斜线表示地面，以下同理)，图2(b)为显示屏幕的俯视图，图2(c)为显示屏幕的左(或右)视图，图2(d)为显示屏幕的立体图。从图2的四幅图中可以看出，所述显示屏幕的筒状部的横截面为圆形，两个端部为半圆球形，整个壳体结构类似于胶囊状。本申请不对所述圆形半径的具体值进行限定，本领域技术人员可以根据实际情况自行设计。
在另一个实施例中，参见图3，图3(a)为显示屏幕的正视图，图3(b)为显示屏幕的俯视图，图3(c)为显示屏幕的左(或右)视图，图3(d)为显示屏幕的立体图。从图3的四幅图中可以看出，所述显示屏幕的筒状部的横截面为椭圆形。本申请不对所述椭圆形的长轴和短轴的具体数值进行限定，也不对所述长轴和所述短轴的比例进行限定，本领域技术人员可以根据实际情况自行设计。
在另一个实施例中，参见图4，图4(a)为显示屏幕的正视图，图4(b)为显示屏幕的俯视图，图4(c)为显示屏幕的左(或右)视图，图4(d)为显示屏幕的立体图。从图4的四幅图中可以看出，所述显示屏幕的筒状部的横截面为带圆角的正方形。当然，在实际应用中，所述筒状部的横截面还可以是带圆角的长方形或其他四边形。其中，带圆角的目的是为了能够与两个端部平滑过渡。本申请不对所述四边形边长的具体数值，以及所述圆角的半径r的具体数值进行限定，本领域技术人员可以根据实际情况自行设计。
在另一个实施例中，参见图5，图5(a)为显示屏幕的正视图，图5(b)为显示屏幕的俯视图，图5(c)为显示屏幕的左(或右)视图，图5(d)为显示屏幕的立体图。从图5的四幅图中可以看出，所述显示屏幕的筒状部的 横截面为上下不对称圆形。当然，在实际应用中，所述筒状部的横截面还可以是左右不对称圆形。本申请不对所述不对称圆形的具体参数进行限定，本领域技术人员可以根据实际情况自行设计。
所述图2至图5为筒状部侧壁在轴线截面上呈直线设置的实施例，可以理解的是，上述实施例并不构成对本申请的限定，凡是满足筒状部侧壁在轴线截面上呈直线设置的实施例均在本申请的保护范围内。另外，在图2至图5中的各个实施例中，共同点在于筒状部侧壁在轴线截面上呈直线设置，不同点在于所述筒状部的横截面不同，有的弧度较大，有的弧度较小。对于观众而言，横截面的弧度越小，观看起来越舒适；反之，横截面的弧度越大，观看起来越不舒适。因此，以上四个实施例中，横截面为带圆角的四边形的显示屏幕视觉效果最佳。
下面介绍显示屏幕为全封闭式时，筒状部侧壁在轴线截面上呈弧线设置的各个实施例。
在一个实施例中，参见图6，图6(a)为显示屏幕的正视图，图6(b)为显示屏幕的俯视图，图6(c)为显示屏幕的左(或右)视图，图6(d)为显示屏幕的立体图。从图6的四幅图中可以看出，所述显示屏幕的整个壳体结构为椭圆体，且该椭圆体的横截面为圆形。本申请不对图6中所述椭圆体的具体参数进行限定，本领域技术人员可以根据实际情况自行设计。
在另一个实施例中，参见图7，图7(a)为显示屏幕的正视图，图7(b)为显示屏幕的俯视图，图7(c)为显示屏幕的左(或右)视图，图7(d)为显示屏幕的立体图。与所述图6的显示屏幕相同的是，所述图7中的显示屏幕的整个壳体结构也是椭圆体，但是不同的是，所述椭圆体的横截面为椭圆。本申请不对图7中所述椭圆体的具体参数进行限定，本领域技术人员可以根据实际情况自行设计。
当然，可以理解的是，所述图6和图7的两个实施例是筒状部侧壁在轴线截面上呈弧线设置的特殊情况，当所述筒状部侧壁在轴线截面上呈弧线设置时，所述筒状部的横截面还可以是不对称圆形、带圆角的四边形等。需要注意的是，所述筒状部侧壁在轴线截面上呈弧线或直线设置并不一定指所述筒状部全部侧壁在轴线截面上满足某一种的线的设置，还可以是部分侧壁呈 直线设置，部分侧壁呈弧线设置，例如面朝观众的显示屏幕的侧壁呈直线设置，观众顶部的显示屏幕的侧壁呈弧线设置。
以上实施例描述的是全封闭式壳状结构的显示屏幕，全封闭式显示屏幕的好处在于，观众可以在360度角度、全方位观看显示画面，观众的无边界体验感非常高，但是同时成本也较高。为了节约成本，在实际应用中所述显示屏幕可以采用部分封闭式壳体结构，下面将逐一介绍部分封闭式壳体结构显示屏幕的各个实施例。在实际应用中，由于观众往往不会朝向座椅底部观看显示图像，因此可以将所述显示屏幕的底部“切掉”。
在一个实施例中，参见图8，所述图8为将所述图2的显示屏幕的底部“切掉”后的显示屏幕，其中，图8(a)为显示屏幕的正视图，图8(b)为显示屏幕的俯视图，图8(c)为显示屏幕的左(或右)视图，图8(d)为显示屏幕的立体图。
在另一个实施例中，参见图9，所述图9为将所述图3的显示屏幕的底部“切掉”后的显示屏幕，其中，图9(a)为显示屏幕的正视图，图9(b)为显示屏幕的俯视图，图9(c)为显示屏幕的左(或右)视图，图9(d)为显示屏幕的立体图。
在另一个实施例中，参见图10，所述图10为将所述图4的显示屏幕的底部“切掉”后的显示屏幕，其中，图10(a)为显示屏幕的正视图，图10(b)为显示屏幕的俯视图，图10(c)为显示屏幕的左(或右)视图，图10(d)为显示屏幕的立体图。
在另一个实施例中，参见图11，所述图11为将所述图5的显示屏幕的底部“切掉”后的显示屏幕，其中，图11(a)为显示屏幕的正视图，图11(b)为显示屏幕的俯视图，图11(c)为显示屏幕的左(或右)视图，图11(d)为显示屏幕的立体图。
在另一个实施例中，参见图12，所述图12为将所述图6的显示屏幕的底部“切掉”后的显示屏幕，其中，图12(a)为显示屏幕的正视图，图12(b)为显示屏幕的俯视图，图12(c)为显示屏幕的左(或右)视图，图12(d)为显示屏幕的立体图。
在另一个实施例中，参见图13，所述图13为将所述图7的显示屏幕的底部“切掉”后的显示屏幕，其中，图13(a)为显示屏幕的正视图，图13(b)为显示屏幕的俯视图，图13(c)为显示屏幕的左(或右)视图，图13(d)为显示屏幕的立体图。
本申请对具体“切掉”多少显示屏幕，即所述壳体结构“开口”的程度不做具体限定，在实际应用中，可以根据观众座椅平台的尺寸和位置、显示屏幕的大小等进行确定，其原则是不影响观众在垂直方向上正常观看以及无边界的感觉即可。优选的方式是，至少保证第一排观众正视前方时视线所及的最下方可以看到显示屏幕，一般情况下，人眼垂直视野的下边界为视平线以下70度。
在实际应用中，由于观众往往不会朝向座椅后面观看显示图像，因此可以将所述显示屏幕的后面部分“切掉”。
在一个实施例中，参见图14，所述图14为将所述图2的显示屏幕的后面部分“切掉”后的显示屏幕，其中，图14(a)为显示屏幕的正视图，图14(b)为显示屏幕的俯视图，图14(c)为显示屏幕的左(或右)视图，图14(d)为显示屏幕的立体图。
