    摘要: An apparatus for controlling the quantity of light incident on an image sensor by controlling size or shape of a diaphragm and also by adjusting light transmittance of the diaphragm is provided. The light control apparatus is disposed on the light path of the image sensing device and controls a quantity of light incident on the image sensor. The light control apparatus includes a Guest-Host LCD panel applied no polarizing film and a control unit for reducing the time to take multi-frame detection by driving voltages which are applied to respective pixels of the Guest-Host LCD panel, to be increased at least when taking multiple frames in series. The Guest-Host LCD panel has a plurality of pixels forming closed curves or boundaries on a plane, which are electrically driven individually. Also, the pixels have uniform light transmittance throughout the entire azimuth of the closed curves or boundaries with an origin.

    摘要: The present invention relates to an LCD light-reducing apparatus, and to a vehicle smart mirror using the same, which are to be applied to the interior rear-view mirror or exterior side-view mirrors of a vehicle to protect the vision of the driver of the vehicle from bright lights or glares coming from behind him during nighttime drive. The LCD light-reducing apparatus according to the present invention comprises an LCD panel including at least one liquid crystal cell, and a power supply device for supplying a sufficient electric field to the LCD panel. The LCD cell includes a liquid crystal layer; and two substrate layers opposite one another with the liquid crystal layer at center thereof. The liquid crystal layer is filled with a compound including negative dielectric anisotropic nematic liquid crystals, a chiral material for inducing a cholesteric phase of the nematic liquid crystals to have a pitch of 1 to 4 times the cell gap of the liquid crystal layer, and dichromic dyes for being rearranged parallel to the nematic liquid crystals to transmit or absorb light in accordance with whether the electric field is applied or not. The substrate layer includes a tilted homeotropic alignment layer for arranging the respective nematic liquid crystals and dichromatic dyes in a first arrangement that is vertically aligned to the surface of the substrate layer, and an electrode for generating a sufficient electric field that passes through the liquid crystal layer to rearrange the nematic liquid crystals and dichromatic dyes in a second arrangement that is different from the first arrangement.
