A display device includes a housing with an opening; an electro-optic layer that includes a transmissive-reflective layer and configured to vary reflectivity of incident light; a display provided on the electro-optic layer; a control circuit that controls an operation of the display device; and an actuator that switches the electro-optic layer between first and second postures, wherein the control circuit: controls an operation of the display, generates a trimmed image matching a shape of the opening or a shape of the display, outputs the trimmed image to the display, controls the reflectivity of the electro-optic layer when the electro-optic layer is in the second posture, and does not control the reflectivity of the electro-optic layer when the electro-optic layer is in the first posture, and the display is visible to a driver through the electro-optic layer when the control circuit controls the display to display the trimmed image.

Display system and display device

A display system includes an image capture device, a display device, and at least one of a first illuminance sensor and a second illuminance sensor. The image capture device captures an image rearward of the vehicle. The display device is coupled to the image capture device, and receives at least a portion of the rearward image captured by the image capture device. The first illuminance sensor detects brightness around the vehicle, and the second illuminance sensor detects intensity of light emitted onto a front surface of the display device.

According to one embodiment, a display system includes a display device that displays an image rearward of a vehicle, a first illuminance sensor that detects the brightness around the vehicle, and a second illuminance sensor that detects the intensity of the light emitted onto the front surface of the display device, and the display device includes a housing with an opening on the front side, an electro-optic layer with a transmissive-reflective layer that transmits a portion of incident light and reflects another portion of the incident light, the electro-optic layer being configured to vary the reflectivity of the incident light, a display placed on the rear side of the electro-optic layer and configured to display at least a portion of the rearward image of the vehicle, and a control circuit that controls the brightness of the display based on a value of at least one of first illuminance and second illuminance.
