I also told you that if you really want a good film, you should buy a brand-name professional manufacturer, but at least it should be above 13 yuan.
I haven't put any film on my notebook up to now, and I've used it well all night. I even tore up the trademark on my palm rest to cool it down.
the screen film has an influence on heat dissipation, and the heat generated by the back electrode tube is quite large, so it is not easy for the heat to escape after film pasting, which will accelerate the aging of your screen.
