Description

Shading device for active switching 3D display

technical field

The utility model belongs to the field of shading display equipment, in particular to an active switchable 3D display shading device which can automatically and quickly switch between 3D display and shading effect according to different received signals.

Background technique

In recent years, with the improvement of the quality of life, display technology continues to pursue more realistic and natural image quality, and even in order to meet the demand for real images, it has developed from 2D to 3D to provide the visual experience of virtual three-dimensional space. The principle of stereoscopic display technology is mainly caused by binocular parallax. Since the distance between the left eye and the right eye of human beings is about 6.5 cm, the angles when viewing objects are slightly different, and the received images are slightly different. Therefore, when The brain receives two slightly different images and combines them to form a visual image with depth information, which can make the interpretation of image information more reliable.

However, the positions of the displays are usually fixed, so to allow people to receive stereoscopic images, the left and right eyes must receive slightly different images respectively. At present, 3D stereoscopic display technology can be roughly divided into two categories - glasses type and naked eye type. Glasses type stereoscopic display technology can be further divided into the following types:

1. Anaglyph Glasses are composed of red lenses and blue-green lenses, so that the left and right eyes can filter out images of different colors, so it can produce parallax and form a three-dimensional image. The disadvantage is that some colors will be filtered out, so only grayscale or monotone pictures can be seen.

2. Polarizer glasses are composed of horizontal and vertical polarizing lenses for receiving three-dimensional images composed of different polarized light rays. The disadvantage is that when the head is tilted, the light from the other direction cannot be completely filtered out so that the eyes receive the image from the other eye, causing discomfort when viewing.

3. The shutter glasses (LC Shutter Glasses) are composed of pairs of liquid crystal sheets, which can electronically control the pair of liquid crystal sheets to alternately switch and change color during playback, so that the left and right eyes receive different images. The image produces a three-dimensional effect. This type of shutter glasses is currently the most widely used and has the best stereoscopic image display effect, but the disadvantage is that it needs to use sophisticated electronic control technology, so it is expensive.

4. The helmet-mounted display is equipped with a screen corresponding to the left eye and the right eye respectively, and the two sets of screens have different image signals, and directly use the parallax to form a three-dimensional image. Its disadvantage is that it can only be watched by a single user, and it is expensive and heavy to be inconvenient to use.

However, the above-mentioned shutter glasses and the helmet-mounted display have the best display effects, but both must be manually operated by the user for switching the power switch or adjusting the brightness and image. Generally, there are also sunglasses on the market that use these liquid crystal sheets as a shading effect, and the brightness and darkness of these liquid crystal sheets can be adjusted in multiple stages, which is suitable for users to perform various activities in the sun. The shutter glasses and the sun glasses using liquid crystal as a shading means are all single-function products. Although they are similar in structure, they cannot be used together in function, so they lack practicability and cause unnecessary waste.
