  • Patent number: 11289037
    Abstract: In a display device with two liquid crystal cells, image quality deterioration depending on brightness and darkness of an environment is reduced. For this purpose, as an image signal for a liquid crystal display panel in which a display image is generated by light passing through a rear liquid crystal cell and a front liquid crystal cell, an image processing unit generates a rear image signal for the rear liquid crystal cell and a front image signal for the front liquid crystal cell. This image processing unit performs a spatial filter process on the rear image signal. Then, a filter control unit controls the spatial filter process performed on the rear image signal in the image processing unit on the basis of a detection value of an illuminance sensor that detects illuminance around the display panel.
