电视机使用过程中,荧光屏表面玻璃上有感应静电,容易吸附灰尘,不但影响亮度,还会使反差增大,因此要经常给屏幕除尘去污,以保持玻璃表面的清洁。屏幕去污最好用细软的绒布,其布纹密度大,对防尘、防潮和蔽光有利。什么时候都没有关系。但要注意一点,看电视时一定不能罩上。有的人看电视只把罩拉出一个前脸,露出荧光屏时后面都还蒙在里面,这样会妨碍散热。 During the use of the TV, the surface of the phosphor screen is inductively charged with static electricity, which easily adsorbs the dust, which not only affects the brightness but also increases the contrast. Therefore, it is necessary to regularly decontaminate the screen to keep the glass surface clean. Screen decontamination is best to use soft velvet, the density of its cloth pattern, the dust, moisture and light beneficial. It does not matter when it’s time. But be careful, watching TV must not be covered. Some people watch TV only pull the mask out of a front face, revealing the back of the screen are still covered in the inside, it will prevent heat dissipation.
