All electronics. Now, what devices don't dry well? If moisture gets inside a LCD, then little can remove it. LCDs don't open. But then it should take pressure to get into an LCD.
How LCDs connect to a PC board is interesting. Numerous tiny wires are impeded in a styrofoam like material. Slight pressure of the LCD causes wires impeded in that styrofoam to make contact with the PCB. So it may take time and effort to remove that moisture.
But again, moisture does not cause electronics damage. If left too long, it may cause corrosion. Moisture must be removed so that near zero currents flow in proper directions again.
Appreciate how a cell phone keyboard works. Those switch buttons are not very conductive. But the microprocessor sees a poor conductor make contact. However, if water gets between those PC traces, then the microprocessor thinks multiple or all keys are pressed - and ignores it. So that a cell phone's microprocessor can see a keypress, that membrane (that keeps water trapped for months) must be removed, dried, and restored. IOW labor and care.
I have experimented with removing water using vacuum. IOW put a phone inside a plastic bag, suck all air out with a vacuum cleaner, then let driest air in. Did that about 30 times without success. Not enough. A cell phone could also be dried this way. But expect this technique to take at least hundreds of cycles in a room with very dry air. And the technique assumes the water is not contaminated with other conductive materials such as salt.
