Embodiment Construction

[0051] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] First, the relevant principles are explained.

[0053] For a liquid crystal lens with several independent driving electrodes and a radius of r, the optical path difference OPD1=r when the focal length f1 under a certain group of driving voltages 2 / (2f1), the optical path difference OPD2=r when the driving voltage of each el...

Abstract

The invention discloses a liquid crystal lens zoom processing method and system. The method includes: acquiring the maximum optical path difference and the minimum optical path difference of the liquid crystal lens, and calculating the optical path difference change amount, wherein the optical path difference change amount is the The difference between the maximum optical path difference and the minimum optical path difference; according to the preset focal length adjustment accuracy, the optical path difference change amount is divided into N equal parts, and the optical path difference change amount / N is the step size to obtain N+ 1 optical path difference, and obtain the focal length corresponding to each of the optical path differences; according to the optical path difference distribution curve corresponding to the focal length, simulate each group of driving voltages corresponding to the focal lengths to establish a focal length-voltage lookup table . The preset focal length and driving voltage established by this method have high focal length adjustment accuracy when observing the target object at close range. visual features.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a method and system for zooming processing of a liquid crystal lens. Background technique [0002] At present, for near-eye display devices, stereo vision is formed based on the left and right eyes receiving two slightly different images. Since the human eye lens adjusts its convexity to make objects clearly image on the retina, the focusing distance is the same as that of the eyes. The converging distances on the objects are not exactly equal, so users often feel uncomfortable such as dizziness, and the use of the variable-focus liquid crystal lens technology can effectively alleviate the conflict of visual vergence adjustment. [0003] In order to make the liquid crystal lens have better converging ability, usually at least one side of the upper and lower substrates of the liquid crystal lens contains several or even dozens of electrodes that can be driven independent...
