A polarization switching unit is provided in an optical path of laser light to a projection surface A and periodically switches a polarization direction of the laser light emitted therefrom between p and S polarization. A laser control unit controls laser light sources in synchronization with the switching by the polarization switching unit and determines a driving current corresponding to a grayscale to be displayed on the basis of driving current characteristics for P polarization when the polarization direction of the laser light is the P polarization. In addition, the laser control unit determines the driving current corresponding to the grayscale to be displayed on the basis of the driving current characteristics for P polarization when the polarization direction of the laser light is the S polarization."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image display device","description":"To prevent effectively the flickering of an image due to the switching of a polarization direction while reducing speckle noise.
