Patent number: 11131872Abstract: A mirror display apparatus that subjects a mirror optical element to pulse voltage driving so that a reflectivity in a mirror mode can be changed by means of a duty cycle of the pulse voltage is provided. A mirror display apparatus includes a monitor display device and a mirror optical element disposed on the front side of the monitor display device. The mirror optical element includes a liquid-crystal panel with a reflection-type polarizer disposed on the back side thereof. The mirror optical element has a reflectivity and a transmissivity that are changed in respective directions opposite to each other via electric driving using a voltage applied to the liquid-crystal panel. A control circuit drives the liquid-crystal panel using a pulse voltage and performs control to change the reflectivity and the transmissivity of the mirror optical element by changing a duty cycle of the pulse voltage.Type: GrantFiled: December 28, 2020Date of Patent: September 28, 2021Assignee: MURAKAMI CORPORATIONInventors: Yoshihiro Gohara, Noriyuki Unno, Mina Sugino

Patent number: 10809584Abstract: In a mirror display apparatus, a mirror optical element in which reflectance and transmittance vary in opposite directions to each other by electric driving is disposed on a front surface side of a monitor display device. An operation mode of the mirror display apparatus is switchable between a monitor mode and a mirror mode for use. A temperature sensor is installed to a mirror display apparatus. In the monitor mode, the temperature sensor is used for a temperature control of the monitor display device, or a temperature compensation control related to display quality, or the both. In the mirror mode in which the mirror optical element is in a reflectance-reduced reflection mirror state, the temperature sensor is used for a temperature compensation control of reflectance of the mirror optical element.Type: GrantFiled: June 28, 2019Date of Patent: October 20, 2020Assignee: MURAKAMI CORPORATIONInventor: Yoshihiro Gohara

Patent number: 10259393Abstract: Provided is a mirror display device including a monitor display element for emitting image light vibrating in a first direction in an image display state; and a mirror optical element provided on the display surface side relative to the monitor display element. The mirror optical element can switch reflective and transmissible states. The reflective state is that light vibrating in a first direction from an absorption-type polarization plate side is converted to vibrate in a second direction by a liquid crystal cell to be reflected by a reflection-type polarization plate, and converted to vibrate in the first direction by the liquid crystal cell to be emitted from the absorption-type polarization plate. The transmissible state is that light vibrating in the first direction from a reflection-type polarization plate side is transmitted through the cell as it is, to be emitted from the absorption-type polarization plate.Type: GrantFiled: May 17, 2018Date of Patent: April 16, 2019Assignee: MURAKAMI CORPORATIONInventor: Yoshihiro Gohara
