3D display device, 3D interactive display system and method

Abstract

The invention discloses a 3D (three-dimensional) display device. The light-emitting direction of a 3D display screen of the device is provided with a second photosensitive touch layer and a first photosensitive touch layer in sequence; the first photosensitive touch layer and the second photosensitive touch layer are respectively used for detecting first incidence point coordinates of incident light on the first photosensitive touch layer and second incidence point coordinates of the incident light on the second photosensitive touch layer so as to judge the direction of the incident light. The direction of the incident light can be more accurately judged by the 3D display device disclosed by the invention, and therefore, the accuracy of interactive operation performed by a user on the 3D interactive display device is guaranteed. The invention also discloses a 3D interactive display system and a 3D interactive display method.

Description

Technical field [0001] The present invention relates to the technical field of flat panel 3D display, in particular to a 3D display device, a 3D interactive display system and method. Background technique [0002] 3D display (3 Dimensional Display) If you need to interact with people, such as 3D shooting games, 3D display reports, you can add touch functions to the 3D display to form a 3D interactive display. The touch function can use the light-emitting pen-light-sensitive touch screen system to realize remote touch and realize remote operation of the 3D display. [0003] The objects displayed by the 3D interactive display are virtual, and each object has a 3D coordinate of a three-dimensional position. When the operator uses the light-emitting pen to emit light to the light-sensitive touch screen, the light pen-light-sensitive touch screen system can only determine a 2D coordinate, which will cause a large error in human-computer interaction. [0004] Such as figure 1 As shown, a...

Problems solved by technology

When the operator uses the light-emitting pen to emit light to the light-sensitive touch screen, the light-pen-light-sensitive touch screen system can only determine a 2D coordinate, which will lead to a large error in human-computer interaction

[0004] like figure 1 As shown, a 3D interactive display is composed of a 3D display screen 1 and a light-sensitive touch layer 2. A user 5 points to an object B in the display object 4 of the 3D interactive display with a luminous pen 3 and emits incident light 6 through the luminous pen 3. Due to the incident light 6. There is an incident angle in the vertical direction, so that the position perceived by the light-sensitive touch layer may point to the position of the C object in the display object 4, and the wrong pointing information is obtained, thus affecting the accuracy of the remote interactive operation

[0005] In an existing solution, the user needs to use a light-emitting device that can emit light of two different colors. The light-sensing array of the 3D interactive display device calculates the coordinates by sensing different light intensities of different colors of light. The required light-sensing The structure of the measurement array is complex, the design is difficult, and color filters are required to make different colors of light pass through and present different light intensities. Therefore, it is only suitable for certain displays, such as liquid crystal 3D displays. If it is used for other types of 3D displays, Such as OLED displays, PDP displays, etc., you need to add additional color filters, which not only increases the cost but also seriously affects the brightness
