Description
一、技术领域 1. Technical field
本发明涉及三维(3D)显示技术领域，更具体地说，本发明涉及视差光栅3D显示技术领域。The present invention relates to the technical field of three-dimensional (3D) display, and more specifically, the present invention relates to the technical field of parallax barrier 3D display.
二、背景技术 2. Background technology
视差光栅3D显示器是一种裸眼3D显示器，是世界各国正在开展的新型显示器，有着广泛的应用前景。视差光栅3D显示器是基于双目视差和光栅分光原理实现3D显示效果，它一般由二维(2D)平面显示器上加装光栅而成。其种类分为光栅前置式和后置式，光栅有柱面光栅或狭缝光栅。2D平面显示器包括常规液晶显示器LCD、等离子显示器PDP、场发射显示器FED、有机电致发光显示器OLED等平面显示器。Parallax barrier 3D display is a naked-eye 3D display. It is a new type of display that is being developed by countries all over the world, and has broad application prospects. The parallax grating 3D display is based on the principle of binocular parallax and grating light splitting to achieve 3D display effects. It is generally formed by adding a grating to a two-dimensional (2D) flat-panel display. Its types are divided into grating front type and rear type, and the grating has cylindrical grating or slit grating. 2D flat panel displays include conventional liquid crystal displays LCD, plasma displays PDP, field emission displays FED, organic electroluminescent displays OLED and other flat displays.
视差光栅3D显示器通常都采用一个平面屏来显示3D场景，3D图像的每个像点到观察者眼睛的连线一定要和平面显示区域相交，被显示的3D场景将被限制在一个锥形区域内，只有在这个区域类的3D图像才是合理的。例如，对于显示面积一定的平面3D屏，要显示一个较大的3D场景，很显然是不可能的，如附图1所示，3D场景在锥形空间之外的部分是无法显示出来的。解决办法目前有加大显示屏面积，以及采用几个显示屏拼接的方法。前一种方法使得整个显示系统变得庞大臃肿，后一种方法技术难度较大。Parallax barrier 3D displays usually use a flat screen to display 3D scenes. The line connecting each image point of the 3D image to the observer's eyes must intersect the plane display area, and the displayed 3D scene will be limited to a cone-shaped area. 3D images are reasonable only in this area. For example, for a flat 3D screen with a certain display area, it is obviously impossible to display a larger 3D scene. As shown in Figure 1, the part of the 3D scene outside the tapered space cannot be displayed. The solution currently includes increasing the area of the display screen and splicing several display screens. The former method makes the entire display system bulky and bloated, while the latter method is more technically difficult.
目前，非平面的2D显示屏已经大量存在，例如阴极射线管显示屏、可以弯曲的柔性显示屏以及投影显示中的弯曲屏等，但相应的非平面视差光栅3D显示屏还没有。At present, there are a large number of non-planar 2D display screens, such as cathode ray tube display screens, flexible display screens that can be bent, and curved screens in projection displays, etc., but there is no corresponding non-planar parallax barrier 3D display screen.
三、发明内容 3. Contents of the invention
本发明提出一种非平面视差光栅3D显示屏，其特征是采用能显示多个视差图的非平面2D显示屏加装非平面视差光栅构成，如附图2所示。非平面包括弯曲面、折叠面等。本发明能实现平面视差光栅3D显示屏同样的3D场景显示效果，即显示的3D场景不会因显示屏弯曲或折叠而变形。本发明的显示屏具有紧凑的特点，特别使较大较复杂的3D场景得到效果很好的完整显示，同时避开了拼接型视差光栅3D显示屏的技术难度。本发明丰富了视差光栅3D显示屏的种类。The present invention proposes a non-planar parallax grating 3D display screen, which is characterized in that it adopts a non-planar 2D display screen capable of displaying multiple parallax images and is composed of a non-planar parallax grating, as shown in FIG. 2 . Non-planar surfaces include curved surfaces, folded surfaces, etc. The invention can realize the same 3D scene display effect as the plane parallax grating 3D display screen, that is, the displayed 3D scene will not be deformed due to the bending or folding of the display screen. The display screen of the present invention has the characteristics of compactness, especially enables large and complex 3D scenes to be completely displayed with good effects, and meanwhile avoids the technical difficulty of splicing parallax barrier 3D display screens. The invention enriches the types of parallax barrier 3D display screens.
