Embodiment Construction

[0060] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0061] refer to Figure 4 The LED aerial projection display includes an aerial imaging system, the aerial imaging system includes an image light source, and also includes an optical imaging system that combines the light from the image light source in the air to form an image, the image light source adopts an LED display, and the LED display includes at least one LED display array.

[0062] Because the LED display itself emits light, using the LED display as the image light source has the characteristics of simple structure and superior optical performance. Light imaging systems project light sources into the air.

[0063] refer to figure 1 , the LED display includes an LED display array, and the LED display array includes at least two groups of...

Abstract

The invention relates to the display field, especially to an LED aerial projection display. The LED aero-projection display comprises an aerial imaging system and an optical imaging system; and the aerial imaging system includes an image light source and the optical imaging system is used for enabling lights from the image light source to be intersected and carrying out imaging. The display is characterized in that: the image light source employs an LED display that includes at least one LED display array. Because the LED display can be luminous by itself, the LED display is used as an image light source; and the LED aerial projection display has advantages of simple structure and excellent optical performance and the like. And the optical imaging system is capable of projecting an image light source in the air.

Description

technical field [0001] The present invention relates to the field of electronics, in particular to the field of display. Background technique [0002] Display screens bring a lot of convenience to people's life and work. Existing display screens include cathode ray tube (Cathode Ray Tube) display screens, liquid crystal display screens, LED display screens, and plasma display screens. Among the above-mentioned display screens, the LED display has the advantages of low cost, long life, good color, fast response, etc., but there are still some deficiencies in the mechanism itself and the production process of the LED display, so it cannot meet the market demand. So that LED displays with various excellent characteristics cannot be popularized in the market so far. [0003] In addition, there is an increasing demand for stereoscopic display. The current stereoscopic display technology mainly needs to wear stereoscopic glasses. Glasses-free 3D technology is still immature. ...
