Active matrix focusing lens and focusing glasses having same

Abstract

An active matrix focusing lens and focusing glasses having the same are provided. The active matrix focusing lens comprises a lens body and a transparent phase modulator which includes a first substrate, a second substrate, a plurality of data electrode lines and scan electrode lines which are disposed on the first substrate and spaced apart from each other, a plurality of photoelectric switches disposed on the first substrate and electrically connected to the data electrode lines and the scan electrode lines, and a liquid crystal layer disposed between the first substrate and the second substrate. Any two adjacent data electrode lines and the scan electrode lines collectively define a pixel region. When a voltage is applied to the photoelectric switches, the corresponding pixel regions have different refractive indices, and the focal length of the active matrix focusing lens is changed, so that the same pair of lenses can be switched to look far or near, without preparing multiple glasses to cope with looking far or near. It is also possible to adjust different focal lengths for respective pixel regions so that different positions of the entire lens can have different focal lengths at the same time.

Description

technical field [0001] The invention relates to a lens and glasses, in particular to an active matrix focusing lens and focusing glasses with the lens. Background technique [0002] When users who already have myopia and wear myopia glasses, as they get older, their eyes appear presbyopia, which makes them unable to focus on close objects. It is often necessary to use multiple pairs of glasses to assist the eyes to focus, so that See things near and far clearly. [0003] Therefore, presbyopic glasses with multi-focal lenses have been developed to solve the inconvenience of carrying multiple pairs of glasses. Commonly used bifocal lenses such as bifocal lenses use spatial division of a single lens, and design different diopters on the upper and lower halves of a single lens, allowing users to use the upper half of the lens when looking at a distant view the lower half of the lens when reading. However, it is easy to form a discontinuity between the upper and lower halves o...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this technology is that the liquid crystal is arranged in a specific area of ​​the lens, so that the change of the thickness of the liquid crystal is easily perceived by the human eye, thereby affecting the user's visual experience, and due to the limitation of the structure, the switching of the diopter cannot be performed. Continuous switching, with only two-stage switching
