The general situation is caused by external extrusion. May be in the process of using the LCD advertising machine, accidentally with a finger to its press caused by the inability to screen damage. Although a few presses will not affect the service life of the LCD screen, but we still do not recommend that you use your fingers to press the LCD screen.

This is a normal phenomenon, because this is the display card interference with the signal. By automatically or manually adjust the phase can be solved.
Of course, we do not encounter the above problems, usually the LCD advertising machine should also be well cleaned and maintained, so what do we need to pay attention to when cleaning the LCD advertising displays?
When we are cleaning the LCD advertising machine, the shell with a cotton cloth with water wipe on it, do not use any cleaning agent, or the shell will lose its proper luster. When cleaning the LCD screen, use a soft object similar to glasses cloth or lens paper soaked in a little alcohol to wipe, note that the action must be gentle, so as not to scratch the screen, and prohibit the use of wet towels to wipe, because this moisture will enter the screen and thus lead to the machine's internal short circuit.
