Spatial stereoscopic display device (Chinesisch)

Freier Zugriff

The invention relates to the technical field of three-dimensional display, in particular to a spatial stereoscopic display device. The spatial stereoscopic display device comprises a backlight module,an optical rendering module, a spatial light modulator and a light modulation module. The backlight module is used for providing parallel or nearly parallel illumination light beams for the spatial light modulator. The optical rendering module is used for calculating a gray value of each pixel of the spatial light modulator in each time period according to a to-be-displayed three-dimensional virtual object, outputting the gray values to the spatial light modulator, calculating a light beam deflection angle of each array unit of the light modulation module according to the to-be-displayed three-dimensional virtual object and outputting the light beam deflection angles to the light modulation module. The array units of the light modulation module are in one-to-one correspondence with the pixels of the spatial light modulator, and angle deflection control is carried out on the light beams corresponding to the pixels of the spatial light modulator. The spatial three-dimensional display device provided by the invention can solve the problem that the human eyes are not consistent in convergence.

本发明涉及三维显示技术领域,具体而言,涉及种空间立体显示装置。该空间立体显示装置包括:背光模组、光学渲染模组、空间光调制器及光调制模组。通背光模组用于为空间光调制器提供平行或近平形的照明光束。光学渲染模组用于根据待显示的三维虚拟物体计算空间光调制器的每个像素在每个时间段内的灰度值并输出到空间光调制器上,以及根据待显示的三维虚拟物体计算光调制模组的每阵列单元的光束偏转角度并输出到光调制模组上。光调制模组的阵列单元与空间光调制器的像素对应,对空间光调制器每个像素对应的光束分别进行角度偏转控制。本发明提供的空间立体显示装置能够解决人眼的汇聚和辐辏不致问题。
