The invention provides a digital video anti-dazzle windshield of an automobile, and belongs to the field of anti-dazzle technologies. In order to reduce the harmful effect on a driver of the automobile by lamplight of automotive headlamps on the opposite travelling line when automobiles meet at night, the following technical measures are taken, a liquid crystal screen (1) and a camera (2) are installed on the automobile (3), the camera (2) is connected with a digital video processing circuit, the digital video processing circuit is connected with the liquid crystal screen (1), and the liquid crystal screen (1) is composed of a plurality of independent pixels. The digital video anti-dazzle windshield has the advantages that as the camera (2) is installed on the automobile, image positions of the lamplight of the automotive headlamps on the opposite travelling line are captured; the pixels of corresponding points of the liquid crystal screen (1) on the automobile are controlled through signals output by the digital video processing circuit, the transparency of the pixels of the corresponding points of the liquid crystal screen are reduced, or the pixels become opaque, and the luminous flux of the lamplight, reaching the eyes through the liquid crystal screen, of the automotive headlamps on the opposite travelling line is weakened or blocked and cannot be irradiated to the driver.
