Introduction to IPS Technology
Before diving into the specifics of IPS glow, it’s essential to understand the basics of IPS technology. IPS is a screen technology designed to solve the main limitations of TN (Twisted Nematic) matrices in the late 1990s. It was developed to improve upon the limitations of TN technology, particularly in terms of color reproduction and viewing angles. IPS panels are known for their excellent color accuracy, wide viewing angles, and good brightness levels, making them a popular choice for professionals and gamers alike.
How IPS Panels Work
To grasp the concept of IPS glow, it’s helpful to know how IPS panels function. In an IPS display, the liquid crystals are aligned in a plane parallel to the substrate. When an electric field is applied, the liquid crystals rotate, allowing the light to pass through or be blocked, thereby creating images on the screen. This unique alignment of liquid crystals is what enables IPS panels to offer better color consistency and wider viewing angles compared to other technologies like TN.
What is IPS Glow?
IPS glow refers to the visible glow or light leakage that can be observed around the edges or corners of an IPS monitor, particularly when the screen is displaying a dark or black image in a dimly lit room. This glow is more noticeable in certain conditions, such as when watching movies with dark scenes or playing games with a lot of dark environments. The glow can vary in intensity and color, depending on the monitor and the specific IPS panel used.
