Temperature control system and method for projector, and projector

Abstract

The invention relates to a temperature control system for a projector. The temperature control system for the projector comprises a control apparatus and multiple liquid crystal screens, polaroids and radiating apparatuses which are arranged correspondingly, wherein the control apparatus is connected with the multiple radiating apparatuses separately; the control apparatus is used for collecting the actual deflection efficiency of the multiple liquid crystal screens separately, and controlling the multiple radiating apparatuses to radiate the multiple polaroids according to the actual deflection efficiency, wherein the actual deflection efficiency refers to the pixel percentage of any one of the three-primary colors. According to the control system, the operating voltage of the radiating apparatuses can be controlled properly by sampling the actual deflection efficiency of the liquid crystal screens so as to radiate and lower temperature of the polaroids, so that damage to the polaroids caused by overhigh temperature can be prevented; and the noise of the projector can be reduced to a certain degree while the safe use of the projector is ensured so as to improve the quality of the projector. In addition, the invention also provides a temperature control method for the projector, and the projector.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a projector temperature control system and method, and a projector. Background technique [0002] In modern society, projectors are used more and more widely, and people's requirements for the quality of projectors are also getting higher and higher. The most important thing is the service life of the projector. When people use the projector, they don't want problems. The place where the projector is prone to problems is the polarizer of the projector. When the projector is working, it can control whether the light passes through the polarizer by controlling the deflection of the liquid crystal screen. If all the light passes through the polarizer, the polarizer does not absorb light waves, and the temperature is the lowest at this time. Conversely, if the light does not pass through the polarizer at all, the polarizer of the projector absorbs all light waves, and ...

AI Technical Summary

Problems solved by technology

However, when the projector is actually working, the polarizer will only absorb part of the light. At this time, the temperature margin of the polarizer will be large, and the purpose of cooling cannot be accurately achieved.
