Problems solved by technology

However, the more parallax sequence images contained on the display screen, the thicker the images, and the more difficult it is to realize video images
Only two parallax images are needed to see stereoscopic images, and other parallax image information is prepared for other angles. Adding parallax images to increase the viewing angle will make the image rougher for a display screen with limited pixels, enabling the realization of stereo The displayed practical value has been greatly affected by the

Embodiment Construction

[0007] 1. Install a sensor in the middle of the upper or lower frame of the display screen to detect the viewing position of the human eye. The lens of the sensor can be a spherical lens, a cylinder lens or a pinhole, a slit, and behind the lens is a row of thermal or photosensitive elements. The heat of the head; the photosensitive emits infrared light next to the lens, reflected by the face or eyes of the person, and received by the sensor. The sensor compares the electrical signal strength of a row of thermal or photosensitive elements. If the strength of the electrical signal of the element is higher than that of the photosensitive element in other positions, the sensor sends a signal to notify the display device to do the corresponding processing.

[0008] 2. When there is a signal from the sensor, the display software uses DIRECTX technology or OPENGL technology to control the graphics card, and discard the first column of data on the video memory, that is, discard the fi...

Abstract

The invention relates to a method for avoiding blind zones in an optical grating three-dimensional display screen, which uses a sensor to identity the positions of human eyes, adjusting the relative position of an optical grating and an image when the human eyes are in a blind zone to actively avoid the lateral inversion of parallax images and solve the blind zone problem, thereby reducing increased multi-parallax images resulted form taking account of blind zones, making the display screen with limited pixels display images more finely, and preventing the blind zones from influencing the market acceptance of optical grating three-dimensional display products due to blind zones.

Description

technical field [0001] The invention relates to a grating stereoscopic display, in particular to a method for avoiding blind areas of a grating stereoscopic display screen. Background technique [0002] The grating stereoscopic image can realize the stereoscopic naked-eye viewing, which is a good way of viewing the stereoscopic image. In recent years, people have applied it to the display screen to make it develop better. But raster images have blind spots, where the left-right parallax of the image seen in the blind spots is reversed, which looks uncomfortable (see attached image). In order to expand the viewing angle and reduce the blind area, a raster image often needs multiple parallax image sequences to widen the effective viewing area. However, the more parallax sequence images contained on the display screen, the thicker the images and the more difficult it is to realize video images. Only two parallax images are needed to see a stereoscopic image. Other parallax im...
