Description

高清裸眼便携式立体影视播放器左右目视反光镜构成结构 Technical Field
本发明涉及一种在高清裸眼便携式立体影视播放器能够实现裸眼观看立体视频画面的高清裸眼便携式立体影视播放器左右目视反光镜构成结构，属微型立体视频播放观看器专用部件总成制造领域。
Background Art
1、CN101594549A、名称'一种可裸眼观看的立体显示器'，含黑色挡板(2)、右凸透镜(3)、左凸透镜(4)和LCD视频播放器(7)，所述显示器是一个顶面板与底面板互相平行的盒 子，黑色挡板(2)构成所述的盒子的三个侧面，右凸透镜(3)和左凸透镜(4)分别以它们的光轴互相平行的方式并排地安装在所述顶面板的凸透镜安装圆孔中，右凸透镜(3)的光轴与左凸透镜(4)的光轴之间的距离为6～7cm，LCD视频播放器(7)含屏幕(1)，其特征在于，屏幕(1)是LCD视频播放器(7)的显示器，屏幕(1)含右屏幕(10)和左屏幕(11)，右屏幕(10)和左屏幕(11)分别位于屏幕(1)的右半部分和左半部分，右屏幕(10)和左屏幕(11)以分别位于右凸透镜(3)和左凸透镜(4)正下方的方式固定在所述底面板的上表面，LCD视频播放器(7)的屏幕(1)与右凸透镜(3)和左凸透镜(4)的距离为8～12cm，LCD视频播放器(7)还含usb数据传输口(6)，usb数据传输口(6)安装在黑色挡板(2)的左侧面板上。见附图5和6。其存在的不足之处：一是该专利写到'右凸透镜(3)的光轴与左凸透镜(4)的光轴之间的距离为6～7cm'，'LCD视频播放器(7)的屏幕(1)与右凸透镜(3)和左凸透镜(4)的距离为8～12cm'，说明其光学透镜的焦距最短为8厘米，该专利所示图而屏的排列为并排，并排的单个图像尺寸最大不可能超过人的双眼间距6.5厘米，按正常的影片观看视角应大于40度光学设计，放大倍率要达到3倍以上，镜片直经为2厘米左右(这也符合该专利的凸透镜镜片是小的圆形镜片图示)。由于目镜的直径较小，观看时人眼要紧贴着透镜才能观看，这种方式与市面所售的头戴式立体显示器并无原则上的区别，它并不具备裸眼立体方式那种人眼可上下、左右、前后可自由移动的基本特征。所以，它很难称之谓完美的裸眼立体特性；二是图象宽度为6.5厘米，如果按目前视屏的主流产品LCD屏的分辨率来说最高达到1000个象素，离高清视屏就低了2倍；三是LCD屏的象素在3倍的目镜下观察，可看到较大的象素颗粒，无法作为电影的无颗粒感的基本观看要求。
2、本申请发明人所有在先专利CN90217663，名称'一种立体图对用立体图象显示仪'。具有壳体(1)、平面反光镜(2)、立体图对框架(3)、纵向隔板(4)、漫射板(5)、电光源、连接电光源的导线和电源缄；其特征在于壳体(1)上端固定有平凸透镜屏(6)；透镜屏由二块相同的矩形平凸透镜紧密并列连接组成，透镜的凸面朝向壳体内腔，透镜焦距范围为200~250毫米，透镜屏的长为120~140毫米，宽为80~100毫米，壳体(1)中部倾斜的内壁上固定有矩形平面反光镜(2)，平面反光镜(2)和透镜屏(6)的平面的夹角为45度，壳体中部相对于平面反光镜的内壁上设有直射电光源(7)，壳体下部设置有可活动的立体图对框架(3)，所述框架平面和平面反光镜之间的夹角为45度，壳体(1)内腔自平凸透镜屏到立体图对框架之间中部固定有纵向隔板(4)，立体图对框架(3)下面设有平行于框架(3)的漫射板(5)，漫射柏(5)下设有透射电光源(8)，壳体(1)下部外表台阶上设有直射电光源和透射电光源的转换开关(9)，所过的转换开关(9)以串联形式校入电光源线路之中。见附图2和3。该专利写到传统的立体观片器'采用短焦距目镜观看立体图象时，人眼必须紧贴目镜，双眼相对于目镜可移动活动范围非常小，离开特定的位置立体图像便会消失'。这一专利的缺点是：由于目镜采用了透镜焦距范围是200~250毫米，当目镜为平凸透镜(非望远镜)时，焦距尺寸200毫米＞图像宽度尺寸65毫米，图像的放大率不会超过1倍，因此，按此专利技术所形成的立体图像必定是小尺寸的图像，这可作为某种立体图像观看，却无法达到视场角为40度以上影院那种观看大立体图像的视觉效果。
 Technical Solution
设计目的：避免背景技术中的不足之处，设计一种在高清裸眼便携式立体影视播放器能够实现裸眼观看立体视频画面的高清裸眼便携式立体影视播放器左右目视反光镜构成结构。
设计方案：为了实现上述设计目的。1、左目镜和右目镜直对左目反光镜和右目反光镜，左目反光镜和右目反光镜呈90夹角度的设计，是本发明的技术特征之一。这样设计的目的在于：由于本申请采用左液晶显示屏和右液晶显示屏的显示面分别与左目反光镜和右目反光镜的镜面相对，并且横向设置，这样人的左眼和右眼发出的视线分别通过左目镜和右目镜透射至左目反光镜和右目反光镜，由于左目反光镜和右目反光镜之间的夹角为90度，从而使得左目反光镜和右目反光镜的镜面分别呈45度与左目镜和右目镜相对，其90度设置的左目反光镜和右目反光镜又将人的左眼和右眼发出的视线反射到左液晶显示屏和右液晶显示屏播出的画面上，由于人的两眼有65毫米左右的间距，所以看到同一物体不同角度的两幅图像，经人大脑合成产生立体视觉感。
技术方案：一种高清裸眼便携式立体影视播放器左右目视反光镜构成结构，左目反光镜和右目反光镜呈90度夹角。
 Advantageous Effects
本发明与背景技术相比，左目反光镜和右目反光镜呈90度夹角的设计，实现了左液晶显示屏和右液晶显示屏的显示面与左目反光镜和右目反光镜相对成45度夹角设置，不仅减小了播放观看器体积，方便随身携带，而且实现了裸眼高清观片的目的。
