For screen maintenance，Because LCD screen life is much shorter than CRT. Its aging speed is also much faster, which requires special attention when it is commonly used. For example, in the power management interface, set the time interval of automatically closing the screen when the computer is not responding, or simply develop a habit of closing the screen when you don't need a laptop for a long time, so as to reduce unnecessary screen wastage. In addition, in order to delay the aging of LCD screens, attention should be paid to avoiding exposure to strong sunlight for a long time, using moderate brightness/contrast as far as possible, and reducing the long-term display of fixed patterns (to avoid excessive local aging). Usually, it is necessary to wipe the screen with special soft brush, eyeglasses cloth, Ear Wash ball and so on. If necessary, it is possible to use neutral detergent or a little water to clean the surface stains. Please neglect to use sharp contact points.
