A touch-controlled backlight module including: a light guide board; at least one light-emitting unit for projecting light to an incident surface of the light guide board; and a reflective board positioned on rear side of the light guide board for reflecting the light coming from the light guide board back to the light guide board. A tablet module is laid on rear side of the reflective board. When released from a factory, the tablet module, the light guide board, the light-emitting unit and the reflective board are assembled to form a complete module. The tablet module is responsive of a signal of a nearby electronic pen to output a corresponding signal.
