Liquid crystal glasses

Abstract

The invention discloses liquid crystal glasses which can selectively reduce the highlight brightness during car meeting at night. The liquid crystal glasses comprise a glasses frame, lenses and a head band; an image collecting unit is arranged at the center of the position right ahead of the head band, and a CCD chip, a liquid crystal drive circuit, a microprocessor, a buffer, a power supply, an image recognizing unit, an image processing unit, an information extracting unit and a gray level data generating unit are arranged in the head band.

Description

technical field [0001] The invention relates to a liquid crystal spectacles, in particular to an anti-glare liquid crystal spectacles with a headband. Background technique [0002] When the driver is driving at night, the oncoming cars will inevitably have to turn on the high beams, which will put pressure on the driver's eyes especially when passing by. At this time, drivers usually remind each other politely, turn off the high beams, and slow down the driving speed. Conditional drivers will wear anti-glare glasses to avoid glare. [0003] In the prior art, anti-glare glasses for meeting cars at night, such as polarized glasses, colored glasses, liquid crystal light valve glasses, etc., are used. For polarized glasses and tinted glasses, because they filter out a large part of all the light, it will cause the driver's entire vision to be darkened, which brings more challenges to the dark night. [0004] In the prior art, there are also proposals for photochromic glasses,...

Problems solved by technology

This type of glasses has a better effect than the above-mentioned polarized glasses and colored glasses, but it also has the defect of overall darkening of the line of sight

[0005] In the prior art, there are still anti-glare glasses using liquid crysta
