Display assembly of a digital thermometer
<!–
The present invention relates to thermometers, and particularly to a display assembly of a digital thermometer, wherein the actuation of backlight plate is designed to reduce the power lose so as to prolong the lifetime of the thermometer.
To achieve above objects, the present invention provides a display assembly of a digital thermometer which comprises: a heat sensor, a display unit, a backlight plate, and a processor; wherein the heat sensor measures temperature; after measurement of temperature, if it is detected that the temperature is decreased, the processor will actuate the backlight plate for illuminating the display unit. The display unit displays measured temperature values after measurement of temperature. The display unit is actuated with the backlight plate for displaying the measuring data. A buzzer is installed in the thermometer, after measurement of temperature, the buzzer will emit sound. The processor can de-actuate automatically. The thermometer has an adjustment unit.
In some kind of prior art thermometer, a backlight plate is installed at a backside of a display unit. When the temperature is measured, the backlight plate will light up to illuminate the display unit so that the user can view the temperature. When the measurement of temperature is complete, the backlight plate will light up automatically. However, the period after measurement of temperature and before taking out the thermometer will induce the undesired power waste due to the power lose from the backlight plate.
Accordingly, the primary object of the present invention is to provide a display assembly of a digital thermometer, wherein the actuation of backlight plate is designed to reduce the power loss so as to prolong the lifetime of the thermometer.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
