Method for displaying rearward image of vehicle

A display system, comprising:

• an image capture device configured to capture a rearward image of a vehicle;
• and
• a display device configured to be mounted in the vehicle, the display device including:
• a housing;
• an electro-optic layer having variable reflectivity levels of incident light, configured to transmit a first part of the incident light, configured to reflect a second part of the incident light, and being visible from outside of the display device through an opening of the housing of the display device;
• a display provided between the electro-optic layer and a part of the housing of the display device and coupled with the image capture device;
• and a sensor configured to detect an intensity of the incident light incident on the display device, wherein
• the display device varies a reflectivity level of the electro-optic layer within at least a part of the variable reflectivity levels based on the intensity of the incident light incident on a part of the display device, when the electro-optic layer is in a downward posture, a first normal direction of the electro-optic layer extending outward from an inside of the housing through the opening of the housing in the downward posture,
• the display device displays the rearward image of the vehicle on a screen of the display, the rearward image captured by the image capture device, when the electro-optic layer is in an upward posture, a second normal direction of the electro-optic layer extending outward from the inside of the housing through the opening of the housing in the upward posture, the second normal direction of the electro-optic layer in the upward posture being oriented more upward than the first normal direction of the electro-optic layer in the downward posture, and
• the display device nullifies varying of the reflectivity level of the electro-optic layer within the at least part of the variable reflectivity levels of the electro-optic layer based on the intensity of the incident light incident on the part of the display device, when the electro-optic layer is in the upward posture.
