  • Liquid crystal projector cooling system dependent on air pressure and temperature variables
    Patent number: 7564435
    Abstract: A liquid crystal projector provided with a cooling fan comprises a temperature sensor for detecting the internal temperature of the liquid crystal projector, an air pressure sensor for detecting outside air pressure, and a control device for controlling the number of revolutions of the cooling fan on the basis of the temperature detected by the temperature sensor and the outside air pressure detected by the air pressure sensor.
    Type: Grant
    Filed: February 14, 2002
    Date of Patent: July 21, 2009
    Assignee: Sanyo Electric Co., Ltd.
    Inventors: Hisashi Nakamura, Kouji Terami, Toshiyuki Okino
  • Display device and liquid crystal projector
    Patent number: 6698898
    Abstract: In a display device comprising a suction fan for cooling and an air filter arranged on the suction side of the suction fan for cooling, there are provided means for calculating, in a case where the suction fan for cooling is driven, the integrated value of time periods during which the suction fan for cooling is driven, and means for displaying a warning message for causing a user to clean the air filter when the integrated value of the time periods during which the suction fan for cooling is driven is not less than a predetermined value.

  • Liquid crystal projector
    Patent number: 6550920
    Abstract: A liquid crystal projector provided with one or a plurality of cooling fans comprises a temperature sensor for sensing the internal temperature of the liquid crystal projector, and a driving control circuit for controlling the driving voltage of the cooling fan on the basis of the temperature sensed by the temperature sensor. A driving control circuit controls the driving voltage of the cooling fan in proportion to the temperature sensed by the temperature sensor in a case where the temperature sensed by the temperature sensor is within a predetermined range.

  • Liquid crystal projector
    Patent number: 6476560
    Abstract: A liquid crystal projector comprises a reset switch for resetting the operation of a microcomputer, and abnormality recovery means for initializing, when the liquid crystal projector is in a power on mode, other circuits and the microcomputer without stopping a projecting lamp and a cooling fan when the reset switch is turned on.
