Light detection module, light detection method, and display device

The present invention provides a light detection module, a light detection method, and a display device. The light detection module comprises N light sensing circuits, a control circuit, a conversion circuit, and a detection circuit; N is a positive integer; the N light sensing circuits respectively sense light signals of different colors to generate corresponding light currents; the control circuit is used for controlling to provide the light currents generated by the light sensing circuits to the conversion circuit in a time-sharing manner, and is used for controlling the transfer coefficient of the conversion circuit; the conversion circuit is used for converting the light currents according to the transfer coefficient, so as to obtain an analog output voltage; and the detection circuit is used for obtaining the characteristics of the light signals according to the analog output voltage. The present invention can accurately sense the characteristics of different colors of ambient light.
