Publication number: 20240351525Abstract: A display device includes a housing, an electro-optic layer, a display to display at least a portion of a rearward image, and an actuator to switch the electro-optic layer between first and second postures. In the first posture, the display displays the portion of the rearward image. In the second posture, the reflectivity of the incident light varies between at least first and second values based on at least one of a first illuminance or a second illuminance, and the second value is larger than the first value. In the first posture, the reflectivity of the incident light is equal to or more than the second value. The first illuminance indicates brightness around a vehicle and is detected by a sensor. The second illuminance indicates intensity of light emitted on a front surface of the display device and is detected by another sensor.Type: ApplicationFiled: June 28, 2024Publication date: October 24, 2024Applicant: Panasonic Automotive Systems Co., Ltd.Inventors: Akinori OZEKI, Osamu TAKEYASU, Ryuko ARISAWA, Takayuki HIRANO

Patent number: 12054099Abstract: A display device includes a housing, a variable reflectance element, a display to display at least a portion of a rearward image, a display device control circuit, and an actuator to switch the variable reflectance element between first and second postures. In the first posture, the display displays the portion of the rearward image. In the second posture, the display displays the rearward image. In the second posture, the reflectivity of the incident light varies between first and second values of a first and a second illuminance, respectively. The first illuminance indicates brightness around a vehicle and is detected by a sensor. The second illuminance indicates intensity of light emitted on a front surface of the display device and is detected by another sensor. When the display displays at least the portion of the rearward image, the display is visible to a driver through the variable reflectance element.Type: GrantFiled: September 8, 2023Date of Patent: August 6, 2024Assignee: PANASONIC AUTOMOTIVE SYSTEMS CO., LTD.Inventors: Akinori Ozeki, Osamu Takeyasu, Ryuko Arisawa, Takayuki Hirano
