Problems solved by technology
[0011] As mentioned above, after the known projector is started, it usually takes more than five seconds to see the quick-display logo image. In the state of circulation, when the main control unit 11 receives the feedback signal, the execution thread 111 is started to continue the unfinished start-up procedure, so the startup speed of the projector is slow and cannot meet the requirement of fast start (within two seconds after pressing the power button). Therefore, it is necessary to find a way to solve the

The invention relates to a projector and a startup method thereof. The projector comprises a main control unit, a light source drive module, a light source and an imaging unit; the light source is lighted up by the light source drive module to provide an illuminating beam, and the imaging unit is initialized by the main control unit and used for transforming the illuminating beam into an imaging beam. The startup method of the projector comprises the following steps: a startup step, an initialization step and a monitoring step. The startup step starts up the main control unit to execute a startup execution thread and a monitoring execution thread. After the initialization step starts up the execution thread to control the light source drive module to try to light up the light source, the imaging unit is initialized. The monitoring step monitors the execution thread to control whether or not the light source drive module produces a successfully lighted signal.
Description
technical field [0001] The invention relates to a projector and its starting method, in particular to a projector capable of rapidly projecting images and its starting method. Background technique [0002] Due to the popularity of multimedia, coupled with the performance improvement and price reduction of projectors, the market for projectors will be very promising in the next few years. Manufacturers are not only actively developing the commercial projector market, but the super-large display effect of the projector is also the first choice for high-quality home theaters. [0003] refer to figure 1 , figure 1 As a known projector, the projector includes a main control unit 11 for managing and using all resources of the projector, a video input unit 12 for receiving multiple signal sources, a memory unit 13 storing a startup program 131, a The lens unit 14 , an imaging unit 15 , an illumination unit 16 , and an optical unit 17 . The lighting unit 16 includes a light sour...
