[Prior Art] The projector (pro jector) has become the best auxiliary tool for product marketing and business briefing. Conventional projectors use light from a light source to image an image from a computer or video recorder through an image forming element to project an image onto a screen. Using the features provided by the projector, images can be fully rendered on a large projection screen for simultaneous viewing by multiple people. However, most users who need to use the projector do not fully understand the meaning of the lights displayed on the projector. In addition, many projectors are hung on the ceiling. Since the projector has a considerable distance from the user, the user cannot see the pattern or text on the surface of the projector. When the user presses the command button on the remote control, the projector can only wait for the light bulb and the image in the projector to project the light and the image normally. Furthermore, the light source bulbs in the projector, such as the high pressure mercury lamps currently used in the past, cannot project enough light after the power source is turned on, but slowly increase the brightness of the light. As a result, the user needs to wait patiently for the lamp to emit enough brightness to display the state of the projector, thus wasting the user's waiting time to determine if the projector is operating normally. In view of this, there is a need to develop a set of state-of-the-art information display system suitable for the projector, which can immediately project its state information onto the display screen when the projector power is turned on, so that the user can understand the projection.
