I stand corrected! There is a "fluid-like" substance in an LCD that retains properties of both a liquid and a solid. Therefore, this substance could also be considered "solid-like."

However, that pattern is defined quite clearly in wikipedia as a texture that takes place in the Nematic phase of Liquid Crystals (LC), which happens to be it's "fluid-like" state.

Picture of the texture:

Because of the characteristics of LC and the many phases that it can change to and from, those textures can appear in certain phases due to the level of isotropy vs. anisotropy, where the higher the isotropy of the LC the more random the order of it's molecules will be and vice-versa. That is directly related to the temperature. Higher temperature = higher isotropy = less structured molecules = more likely to have random patterns as OPPOSED to lower temperature = higher anisotropy = more structured molecules = less likely to have random patterns. Anisotropy and Isotropy are inversly related. Temperature and Isotropy are directly proportional.(http://www.doitpoms.ac.uk/tlplib/ani...idcrystals.php)

In short, temperature changes can cause those patterns.

So back to my original prediction: The pattern on his screen could have been due to leaving it in a hot car. Or any extreme temperature condition might cause it. As far as the fix, I don't have one. Get it replaced?
