Problems solved by technology

[0004] In addition, the light source bulb in the projector, such as the high-pressure mercury lamp commonly used at present, cannot project enough light as soon as the power is activated, but gradually increases its luminous brightness
As a result, the user needs to wait patiently for the lamp to emit enough brightness to display the status information of the projector, thus wasting the user's waiting time to determine whether the projector is working normally

Abstract

The invention relates to an image display device, which includes a projector and a screen capable of displaying real-time status information. In addition to the main projection system that can form an image from the image data from the image source and project the image on the screen, the projector also includes a secondary projection system that can be used when the projector is powered on and the primary projection system can Before the projected image is displayed on the screen, the status information of the projector is projected on the screen. The projector of the invention can reduce the time for users to wait for the operation of the main projection system, prolong the life of the light bulb of the main projection system, and will not interfere with the normal projected image.

Description

technical field [0001] The invention relates to a projector, in particular to a projector and an image display device with real-time status information display. Background technique [0002] The projector has become the best auxiliary tool for product marketing and business presentations. A traditional projector uses light from a light source to form an image from a computer or video recorder through an image forming unit, and then projects the image onto a screen. Using the functions provided by the projector, the image can be completely displayed on a large projection screen for multiple people to browse at the same time. [0003] 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 is quite far away from the user, the user cannot clearly see the pattern or text on the projector surface. When the user presses the command ke...
