Abstract

A backlight writing device with projection displaying function is capable of displaying an image projected from a projector. The backlight writing device comprises a base, a light emission unit mounted on the base, and a writing board arranged on the base. The writing board is of a light transmittable design to allow light emission from the light emission unit to transmit therethrough. The writing board has an outer surface that allows writing to be made thereon and displays an image projected from the projector. Through the backlighting induced on the writing board by the light emission unit, the light-transmittable writing board is switchable between a projection displaying condition where an image projected from a projector can be displayed and a graphics and text displaying condition where graphics and text scratched on the board are displayed. This reduces waste of space and is ready for viewing the image projected on the writing board or graphics and text scratched on the writing board.
