投影机日常使用维护(国外英文资料) The projector is maintained daily The projector is a precision electronic products, it combines mechanical, LCD or DMD, electronic circuit technology at an organic whole, in the process of using the projector is more delicate, often inadvertently will appear all sorts of surprises. This is true, but if you use the right words in your daily life, you will not be so prone to failure. Lets talk a little bit about how to maintain and use the projectors from the use of the projector and the daily maintenance. ????? Here are the following eight things: ?? The mechanical aspect is strongly anti-collision, extrusion and vibration Because of the earthquake can cause the displacement of the liquid crystal slice, in effect showing convergence of the three pieces of LCD, appear the phenomenon of RGB color dont overlap, and the lens in the optical system, reflection mirror, also can produce deformation or damage to the effect the image projection, and zoom lens will make rail damage under impact, cause lens jammed, lens rupture cant even use. Pay attention to ambient dust and ventilation heat We currently use polysilicon LCD plate usually only 1.3 inches, or even just 0.9 inches, and already 1024 x768 or 1024 x600 resolution, that is to say, each pixel is only 0.02 mm, enough dust particles blocking it. But due to the projector LCD plate heat usually have fully dedicated fan to dozens of litres per minute air flow on the cooling air supply, high speed air flow through the strainer mesh could also after placing tiny dust particles, they mutual friction produce electrostatic adsorption in the cooling system, which will impact on the projection screen. Therefore, it is very important to prevent dust in the environment of projectors, and smoking is strictly forbidden, as soot particles are more easily attached to the optical system. So regularly or regularly clean the dust filter at the wind. Currently polysilicon LCD panels are more afraid of high temperature, a
