A method for reminding the viewing area of ​​naked-eye 3D display

Abstract

The invention discloses a naked eye 3D display watching area indicating method. The method includes a 3D display and an indication light source device. A watching area is arranged in front of the 3D display. The indication light source device is mounted in a specific area of the 3D display or a specific space of the watching area. Through light beam combination of the indication light source, an optimal watching area is formed on the ground in front of the display through projection. No matter one or more persons stand in front of the display, the method is applicable and is also convenient for promotion. In order to reduce interference to users, the indication light source can be controlled manually and the indication light source can be switched on in an interrupted manner. The method is suitable for different environments. Automatic adaption can be realized in the optimal watching distance and watching area and 3D effect images can be displayed automatically before eyes of audience in the watching area of the LED naked eye 3D display screen. The audience can move at any time and the applicability is good.

Description

technical field [0001] The invention belongs to the technical field of naked-eye 3D display, and in particular relates to a method for reminding a viewing area of ​​a naked-eye 3D display. Background technique [0002] Glasses-free 3D technology allows people to see 3D effects on the screen without wearing 3D glasses. In principle, it uses the "parallax barrier" technology similar to the human eye to control the left and right eyes to see different images, and then uses the visual imaging principle of the human eye to form a 3D depth effect. At present, there are glasses-free 3D TVs, mobile phones, PADs and other products on the market. [0003] From the perspective of existing technologies, naked-eye 3D can be divided into three types: light barrier type, lenticular lens technology and pointing light source. When watching, the viewer needs to maintain a certain position with the display device to see the image with 3D effect (3D effect is greatly affected by the viewing a...

Problems solved by technology

The disadvantages of this method are: 1. It is necessary to configure a camera with 3D recognition capability, which increases the hardware cost; 2. Before viewing 3D content, the user needs to open the recognition software to check whether it is in a suitable observation area, and then adjust the position before proceeding. Watching; 3. When playing different 3D content, the best viewing area may change. This method cannot achieve automatic adaptation, and manual operation and identification are required every time.

The disadvantage of this method is that it can only be adjusted for a single person watching, and it cannot be resolved when there is a conflict (some people look straight at it, and some look back) when multiple people watch it
