  • Patent number: 11628709
    Abstract: The present disclosure provides an anti-glare device, a control method and a vehicle. The anti-glare device includes a sensing circuit, a driving circuit and an electrically-controlled color-variable thin film. The sensing circuit is configured to acquire status information about the vehicle in a running state. The driving circuit is configured to generate a driving signal for the electrically-controlled color-variable thin film in accordance with the status information. The electrically-controlled color-variable thin film is arranged on a front windshield of the vehicle and configured to change a transmittance to external light beam in accordance with the driving signal.
