Embodiment 1

[0066] Due to the natural optical anisotropy of liquid crystals, most liquid crystal devices only work on polarized light in a specific polarization direction. The liquid crystal lens spectacle lens only has the function of optical convergence or divergence imaging for linearly polarized light parallel to the initial orientation direction of the liquid crystal or in the same direction as the two-dimensional plane where the liquid crystal molecules rotate. For natural light or light with other polarization directions, when it passes through the above-mentioned liquid lens, some components of the light will be converged or diverged by the liquid lens, while the other part will not be affected by the liquid lens and keep the original characteristics to continue to propagate , which will interfere with the human eye, causing problems such as ghosting and even dizziness. Therefore, the existing liquid crystal lens devices need to cooperate with linear polarizers to work normally. H...

Embodiment 2

[0086]This embodiment provides an adjustable liquid lens lens (not shown in the figure). In the first embodiment, the difference from Example 1 is that the second electrode layer and the third electrode layer are common electrode layers; The first electrode layer includes a plurality of first sub-pixels arranged in an array; the fourth electrode layer includes a plurality of second sub-pixels arranged in an array. There is an optical glue layer between the second substrate and the third substrate. This solution helps to increase the convenience of connecting the driver chip and the FPC circuit board. Those skilled in the art should understand that the first substrate and the fourth substrate may have a larger size than the second substrate and the third substrate as required.

Abstract

The invention relates to an adjustable liquid lens, optical vision correction glasses and a control method of the adjustable liquid lens. The adjustable liquid lens comprises a first substrate, a second substrate, a third substrate, a fourth substrate, a first liquid crystal layer and a second liquid crystal layer which are arranged in a stacked manner; the liquid crystal molecules in the first liquid crystal layer are approximately arranged and deflected in a first series of planes which are parallel to each other; liquid crystal molecules in the second liquid crystal layer are approximatelyarranged and deflected in a second series of mutually parallel planes; the first series of planes are orthogonal to the second series of planes; wherein the first to fourth substrates are respectivelyprovided with first to fourth electrode layers; the adjustable liquid lens further comprises a plurality of first sub-pixels and a plurality of second sub-pixels. Each sub-pixel comprises a thin filmtransistor and a transparent pixel electrode. According to the adjustable liquid lens, optical modulation can be carried out on natural light in any polarization state from an external object, the optical transmittance of the intelligent vision optical lens is increased, and unnecessary light intensity loss is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal lenses, in particular to an adjustable liquid lens lens, optical vision correction glasses and a control method thereof. Background technique [0002] Traditional optical glasses used to correct human eyesight usually use transparent optical resin or optical glass material with specific refractive index to melt into molds, and apply mechanical processing (cutting, grinding, polishing) according to the pre-designed Optical lenses or compound lenses that can be used to correct the vision of the human eye are processed by lens morphology. Such optical or compound lenses usually have only one specific focal length. When the human eye is used in different scenarios, the pupil lens will automatically adjust according to the distance of the target object to see the object clearly. For example, when reading a book or watching a computer screen at a close distance, the pupil lens of the human eye w...
