After using the projector for a long time, you may find that the picture projected by it is not as clear as before, which may be because it has not been cleaned for too long
So how does the projector remove dust? Today, the author will talk about the dust removal method of the projector and several matters needing attention in the dust removal process 1： Specific parts of the projector that need dust removal 1
Surface cleaning of LCD panel, polarizer, dichroic lens, FBS lens, compound eye lens, reflector, lens and other components of Projector 2
Cleaning of internal surface of projector bulb and lamp surface lens 3 cleaning of projector filter screen, fan blade and ventilation channel 4 dust removal on the surface of main circuit board, power board, lamp power board and signal interface circuit board 2： Introduction to dust removal method of Projector Physical cleaning method: first, use the air pump to conduct primary dust removal on the surface and interior of the whole machine, and then use advanced cleaning agent, special cotton swab and advanced lens paper for the optical path (such as liquid crystal module and lens) to remove dust and clean the surface of the lens step by step, so as not to damage the internal molecular structure of any lens
However, this method has very high requirements for the technical level of operators
Once the positioning of LCD panel and lens is damaged, there will be image dislocation, color edge and other phenomena
Only assembly and debugging is the work that ordinary technicians cannot complete successfully, so there is a certain risk of optical path dust removal

The ultrasonic uses the huge energy generated by its unique wavelength to break up the dirt, decompose the substances and achieve the purpose of dust removal
This energy is very penetrating and is suitable for cleaning glass lenses and plastic parts
It can not be used to clean special lenses and metal parts made of composite materials in the projector In particular, the liquid crystal panel display unit is very afraid of the merciless destruction of its crystal and molecular structure by the huge energy generated by ultrasound, otherwise it will accelerate the aging of the liquid crystal panel and appear ghosting 3： Precautions during dust removal 1
Please turn off the power supply and unplug the power cord before dedusting the projector 2 general projectors are made of plastic
Benzene, diluent, hair solvent, insecticide, disinfectant, etc
cannot be used, because these will damage the surface coating of the projector 3 gently wipe away the dirt with soft flannelette or cotton cloth 4 if the dirt is difficult to wipe off, soak the cloth in the non harmful detergent diluted with water, screw it dry and wipe the projector 5 clean the dust at the air outlet and air inlet with a vacuum cleaner 6 the cleaning of the filter screen is very important
Be careful not to break the filter screen
You can gently brush it with a soft brush 7 lens is the top priority of projector components
Please use lens cleaning paper for glasses and camera lens to clear the lens
Do not use any liquid cleaners because they will wear the protective film on the lens surface 8 as the lens surface is easily damaged, please be careful not to scratch or hit the lens Here, how to remove dust from the projector and several matters needing attention in the process of dust removal are all over
