Problems solved by technology

As the brightness of the laser increases, the power consumption continues to increase, and the overall temperature of the projector rises, so that the normal operation of the projector cannot be guaranteed.
From another perspective, the heating power consumption of the projector has become a bottleneck restricting the improvement of laser brightness

Embodiment Construction

[0018] Certain words are used to refer to specific components in the description and claims, and those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] figure 1 It is a structural schematic diagram of the projector according to the first embodiment of the present invention. Such as figure 1 As shown, the projector 100 includes a video recognition module 11 , a current controller 12 , a laser 13 , a digital micromirror assembly 14 and a light absorber 15 .

[0020] The video identification module 11 is used for receiving and analyzing video signals to obtain the bright and dark states of the video signals. Specifi...

Abstract

The invention discloses a control method based on a projector and the projector. The projector comprises a video identification module used for receiving and analyzing a video signal to obtain the brightness state of the video signal; a power controller used for dynamically adjusting the laser power according to the brightness state of the video signal; a laser used for controlling the laser brightness of the to-be-emitted laser according to the laser power and emitting the laser; and a digital micromirror assembly used for receiving and reflecting the laser. Through the above mode, the laserbrightness can be dynamically adjusted, so that the heating power consumption of the projector is reduced and the overall temperature of the projector is reduced under the condition that the video perception effect of human eyes is not changed.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a projector-based control method and the projector. Background technique [0002] As technology continues to improve, so does the need for video. The demand for ultra-large screens and high-brightness displays is increasing day by day. In this context, the laser brightness of the projector is required to continue to increase. As the brightness of the laser increases, the power consumption continues to increase, and the overall temperature of the projector rises, so that the normal operation of the projector cannot be guaranteed. From another perspective, the heating power consumption of the projector has become a bottleneck restricting the improvement of laser brightness. [0003] Therefore, how to reduce the heating power consumption of the projector and thus reduce the overall temperature of the projector is an urgent problem to be solved under the condition that the video effect p...
