1. An apparatus for displaying the blood pressure, comprising:

  • a blood-measuring unit for receiving an analog blood pressure signal;

    a photoplethysmography (PPG) signal measuring unit for receiving an analog PPG signal;

    an analog-to-digital converter coupled to the blood-measuring unit and the photoplethysmography (PPG) signal measuring unit, wherein the analog-to-digital converter converts the analog blood pressure signal into a digital blood pressure signal and converts the analog PPG signal into a digital PPG signal;

    an input unit for generating a human data;

    a microprocessor unit coupled to the analog-to-digital converter and the input unit, wherein the microprocessor unit receives the digital blood pressure signal, the digital PPG signal and the human data for generating a different value in response to the digital blood pressure signal and the digital PPG signal, and outputting a pulse wave velocity (PWV) signal in response to the operation of the different value and the human data;

    an LCD driving unit coupled to the analog-to-digital converter and the microprocessor unit, wherein the LCD driving unit receives the digital blood pressure signal and the pulse wave velocity (PWV) signal so as to output a first LCD driving voltage in response to the digital blood pressure signal and output a second LCD driving voltage in response to the pulse wave velocity (PWV) signal; and

    an LCD unit coupled to the LCD driving unit and controlled by the first LCD driving voltage to display the color that corresponds to the first LCD driving voltage and controlled by the second LCD driving voltage to display the color that corresponds to the second LCD driving voltage.
