Abstract
The invention discloses the preparation method of flexible liquid crystal lens and its resistance gradual change electrode, which includes:At least one of first electrode layer and the second electrode lay of the flexible liquid crystal lens are patterned, forms the region that hydrophilic and hydrophobic is different or line width is different, applying conductive material forms resistance gradual change electrode over the region;Or, using optics and chemical means, spatially at least one of the first electrode layer to the flexible liquid crystal lens or the second electrode lay generate gradual change type destruction, cause resistance to generate the difference in spatial distribution, form resistance gradual change electrode.The embodiment of the present invention realizes the independent modulation of the electric field extreme value between flexible liquid crystal lens or the change rate of electric field gradual change, expands the modulation range of flexible liquid crystal lens.
Description
Technical field
The present embodiments relate to technical field of liquid crystal display more particularly to flexible liquid crystal lens and its resistance gradual change electrodes
Preparation method.
Background technique
Currently, in augmented reality, virtual reality and mixed reality field, people are to view with the development that nearly eye is shown
Feel that the requirement of quality is higher and higher, and traditional nearly eye 3D display equipment is eyes formula structure, needs eyes to receive different
Image, since target imaging distance is easy to make one to feel dizzy etc. not equal to screen actual range there are focusing-parallax conflict
It is uncomfortable.
In existing technology, liquid crystal lens array has broad prospects on solving this key request, because with general
