A system for displaying images includes a transflective display panel and a light source module oppositely disposed thereto. The light source module includes a light guide plate, a plurality of first light-emitting diodes (LEDs), a plurality of second LEDs, and a lighting control unit electrically connected to the pluralities of first and second LEDs. The light guide plate includes a first portion and a second portion corresponding to a first display region and a second display region of the transflective display panel, respectively. Each first LED is a white light-emitting diode and transmits an emitted light therefrom to the first display region by the first portion of the light guide plate. The plurality of second LEDs includes red, green, and blue LEDs and transmits an emitted light therefrom to the second display region by the second portion of the light guide plate.
