ABSTRACT:
A system for displaying and capturing images is provided. The system includes a display unit, a detection module. The display unit provides a first light according to a scan signal and a data signal. The detection module captures a second light and comprises a photo detection unit, a transformation unit, and a switch unit. The photo detection unit detects intensity of the second light. The transformation unit transforms the light intensity into a voltage signal. The switch unit outputs the voltage signal according to a selection signal.
