Abstract: A physiological detection device includes system including a first array PPG detector, a second array PPG detector, a display and a processing unit. The first array PPG detector is configured to generate a plurality of first PPG signals. The second array PPG detector is configured to generate a plurality of second PPG signals. The display is configured to show a detected result of the physiological detection system. The processing unit is configured to convert the plurality of first PPG signals and the plurality of second PPG signals to a first 3D energy distribution and a second 3D energy distribution, respectively, and control the display to show an alert message.

Abstract: A method of displaying frame rate includes the following steps. First, a quantity of image display units of a display is detected. Then, a plurality of refresh rate images are provided according to the quantity of image display units and by using an on-screen display manipulation function. A refresh rate of the display is calculated, to provide refresh rate data. One of the refresh rate images corresponding to the refresh rate data is determined, and is displayed on the display.
