A display system includes an EPD and LED matrix with electrophortetic display elements (EPDs) and light emitting display elements (LEDs) of the same numbers, and each of the EPDs is paired with a corresponding one of the LEDs. An LED driver and an EPD driver are used to drive the LEDs and EPDs respectively according as an environment in which the display system is located is in a daytime mode or a nighttime mode. A central control unit is adapted for turning off the LEDs and using only the EPDs for display when the display system is in the daytime mode, and using both the LEDs and EPDs for display when the display system is in the nighttime mode.
