AI Technical Summary

Technical Problem

Existing integrated imaging dual-view 3D display technology has the problem that the horizontal 3D pixel pitch is twice the vertical 3D pixel pitch, resulting in a narrow vertical viewing angle and affecting the viewing experience.

Method used

The design employs a combination of a point light source array, a transmissive display screen, and a polarizing grating. The horizontal pitch of the point light source is twice the vertical pitch, and the polarization units of the polarizing grating are arranged alternately in the vertical direction. The polarization direction of the polarizing glasses corresponds to that of the polarizing grating, ensuring equal horizontal and vertical viewing angles.

Benefits of technology

It achieves equal horizontal and vertical viewing angles for 3D images, improving the viewing experience and solving the problem of narrow vertical viewing angles.
