Document Type and Number:
WIPO Patent Application WO/2022/036692
Kind Code:
A1
Abstract:
The present invention relates to a naked eye 3D display method and an intelligent terminal. The method is applied to the intelligent terminal. A display screen of the intelligent terminal is covered with an electronic 3D optical film, and the intelligent terminal is in communication connection with the electronic 3D optical film. The method comprises: S1, an intelligent terminal performing initialized display on a display screen according to a preset unit image arrangement length; S2, acquiring spatial position information of at least one group of human eyes in front of the display screen; S3, calculating an effective visual area width according to all pieces of spatial position information; S4, obtaining a target grating constant of an electronic 3D optical film according to the effective visual area width; and S5, adjusting the grating constant of the electronic 3D optical film to the target grating constant. According to the present invention, there is no need to increase the number of eyepieces of 3D content by means of multi-eyepiece photography. However, the grating constant of the electronic 3D optical film is adjusted by means of acquiring the spatial position information of a plurality of groups of human eyes, such that viewing by a plurality of people at the same time can be realized, and the resolution cannot be reduced; therefore, the cost is low, and the effect is good.
