THERMOMETER WITH COLOR CHANGING DISPLAY

摘要

The invention includes a thermometer (100) with a backlight and a method for lighting the backlight. The thermometer has a temperature probe section (110) with a temperature sensing element (102), a processor (104) which determines sensed temperature readings of the living being from the signals provided by temperature sensing element. The thermometer also includes a display (106) and a backlight for lighting the display. The backlight is activated upon a command from the processor and the processor determines whether a decrease in the temperature readings exceeds or is equal to a predetermined threshold in order to activate the backlight. The method can include the steps of using the processor to monitor a temperature change indicated by the temperature sensing element. The processor detects a temperature decrease and activates a first color light emitting element (122) to backlight a display if the temperature decrease exceeds or equals a predetermined threshold.
