PURPOSE: A display system is provided to enable an announcer to conduct a presentation effectively by embedding a pont bar generator in the display system. CONSTITUTION: A display system comprises an external image signal processor(110), a display(120), a pont bar generator(130), a signal mixer(140), a pont bar control remote controller(150), a remote controller reception part(160), a micro computer(170), a display driving part(180). The external image signal processor(110) processes an external image signal to generate horizontal and vertical synchronous signals(Hsync,Vsync). The pont bar control remote controller(150) outputs pont bar attribution and position information in a wireless signal, and the remote controller reception part(160) receives the pont bar attribution and position information to transfer the received pont bar attribution and position information to the micro computer(170). The micro computer(170) drives the pont bar generator(130) when the pont bar attribution and position information is received, and the pont bar generator(130) generates a pont bar signal corresponding to the received pont bar attribution and position information in synchronization with the horizontal and vertical synchronous signals(Hsync,Vsync). The signal mixer(140) mixes the external image signal from the external image signal processor(110) and the pont bar signal from the pont bar generator(130) to enable the display driving part(180).
