IPS LCD Glow/Bleed phenomenon explanation

IPS technology offers an ideal viewing experience by providing wider viewing angles.
IPS (In-Plane Switching) monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals and the liquid crystal's ability to shift horizontally creates better viewing angles. The creation of IPS monitors was to provide a solution for the limitations found in TN (Twisted Nematic) monitors.

Here is the comparison of TN & IPS Panel Technologies.

As a result, you can see different colors at the corners of the screen from each angle when it displays dark patterns. Compared to light leakage, this effect is a natural phenomenon on IPS panels.

Your eyes will catch different color behaviors from each side of liquid crystal due to the R/G/B transmittance divergence.

Liquid crystal molecules of VA panel stand upright when no voltage applied (at this time is the dark state). When voltage is applied, the liquid crystal molecules fall in all directions (at this time is the bright state).

Curved surface VA screen is different from flat screen. After voltage applied, liquid crystal cannot fall down completely,
especially at the bend of the screen. It causes in low brightness and the screen forming an oval mura. Therefore, area with lower bending degree will appear brighter , forming a phenomenon that seems like light leakage.

This is a normal glow phenomenon.
