Problems solved by technology

[0002] In the existing technology, shutter-type stereoscopic glasses are generally used. The disadvantage is that the image is quickly switched between the left and right eyes, resulting in serious visual flickering and visual fatigue to the eyes, and the stereoscopic display / flat display cannot be fully compatible.
For liquid crystal or plasma display screens, a cylindrical lens can be used in front of the screen to realize naked-eye three-dimensional display. If this principle is directly applied to the LED three-dimensional large screen, a similar cylindrical lens plate must be installed in front of the LED three-dimensional large screen. Due to the serious reflection of the lens plate, the contrast and saturation of the display screen will be greatly reduced

Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings by means of specific embodiments:

[0058] Such as figure 1 , figure 2 As shown, for a liquid crystal or plasma display screen, a cylindrical lens can be used in front of the screen to realize naked-eye stereoscopic display, such a cylindrical lens such as figure 1 as shown, figure 1 The center is composed of left and right eye image light-emitting pixels 1 and a cylindrical lens 2 . Due to the different display principles of liquid crystal or plasma display screens and large screens, if this principle is applied to large LED screens, a similar cylindrical lens plate must be installed in front of the LED screen, such as figure 2 As shown, such a lens plate will greatly reduce the contrast and saturation of the display screen due to serious reflection.

[0059] The invention includes a controller and a display screen, and a plurality of light-emitting pixel...

Abstract

The invention discloses a stereoscopic large screen based on a cylindrical lens luminous tube, which comprises a controller and a display screen, wherein a plurality of luminous pixels are arranged on the display screen, and the controller controls the luminous pixels to give out light; and cylindrical lenses are arranged on the luminous pixels, and the image visual difference of left and right eyes is formed according to a cylindrical lens luminous principle. The cylindrical lenses are arranged on the luminous tube or the luminous pixels, the large screen made of luminous points or luminous pixels transmits light of left and right images respectively, the images of the left and right eyes enter the corresponding left and right eyes respectively to form the image visual difference of the left and right eyes according to the cylindrical lens luminous principle, and a final stereoscopic image is formed in a human brain; moreover, during watching, people does not need to wear any stereoscopic glasses, and naked-eye stereoscopic large screen display is realized.

Description

technical field [0001] The invention relates to an LED three-dimensional large screen, in particular to a three-dimensional large screen based on a cylindrical lens light-emitting tube. Background technique [0002] Shutter-type stereoscopic glasses are generally used in the existing technology. The disadvantage is that the images are switched quickly between the left and right eyes, resulting in serious visual flickering and visual fatigue to the eyes, and the stereoscopic display / flat display cannot be fully compatible. For liquid crystal or plasma display screens, a cylindrical lens can be used in front of the screen to realize naked-eye three-dimensional display. If this principle is directly applied to the LED three-dimensional large screen, a similar cylindrical lens plate must be installed in front of the LED three-dimensional large screen. Due to the serious reflection of the lens plate, the contrast and saturation of the display screen will be greatly reduced. Con...
