Liquid-crystal zoom lens and electronic device

Abstract

The invention applies to the field of liquid-crystal lenses, and provides a liquid-crystal zoom lens and an electronic device. By connecting conductive media between every two adjacent annular waveband electrodes of transparent electrodes of a substrate and extracting the electrodes through gap channels of the annular waveband electrodes, the invention greatly reduces the number of pins required by a step electric field, is simple in control, reduces the interference in the step electric field, and reduces space area occupied by the substrate.

Description

technical field [0001] The invention belongs to the field of liquid crystal lenses, in particular to a liquid crystal zoom lens and an electronic device. Background technique [0002] With the advancement of optical technology and the increasingly higher requirements of portable devices, traditional optical lens groups cannot fully balance the contradiction between miniaturization and fast wide-range focusing. Liquid crystal lenses have emerged to make up for this deficiency. . [0003] The liquid crystal zoom lens in the form of Fresnel electrodes has a good light convergence effect and can realize the function of an optical lens. Due to its small weight, low cost, convenient focusing, large focal length range, simple control, and good shock resistance, it is expected to replace optical lens. Traditional liquid crystal zoom lenses in the form of Fresnel electrodes generally require the conductive film of Indium Tin Oxides (ITO) to be etched into a band structure, such as ...
