What temperature damages LCD?

（1）LCD displays are usually packaged with silicone. If the working temperature exceeds the solid phase transition temperature (typically 125 °C), the packaging material will become a rubber state and rapidly heat and expand, resulting in an open circuit and failure of the LCD bar screen.

Can water break LCD screen?

A water-damaged LCD screen is usually not repairable, as water can settle between the layers of the liquid crystal display and can be very difficult to dry. In this situation, consider replacing your water-damaged TV with a new one.

Why do LCD displays fade?

The liquid crystal material in an LCD has a transition temperature called the Nematic to Isotropic (N – I) point. This is similar to the transition temperature. Beyond the N – I point, the liquid crystal is no longer in liquid crystal state. As a result, the LCD loses its display effect and an LCD blackout occurs.
