Frequently Asked Questions
The active matrix IPS TFT LCD was developed by Hitachi in 1996 as a solution to the display limitations of TN TFT LCDs (Twisted Nematic) from the late 1980s, which are standard non-IPS LCDs. The TN display is known for its flawed viewing angles, such as inverting colors at extreme angles, and poor color quality. By contrast, IPS displays provide wider viewing angles and higher quality color reproduction by altering pixels to be parallel, rather than perpendicular. In an IPS screen, the liquid crystals run parallel with the panels when energized. In a TN display, the crystals turn perpendicular to the top of the panel. High-performance tablets and smartphones deploy IPS display technology because these electronics are commonly used to watch movies, video chat and store photos. The improved angle and color technology features provide an overall better experience for the user. Creative professionals also benefit from an IPS monitor because an IPS LCD that provides a wider color gamut and greater viewing angles help achieve better aesthetic accuracy and superior results.
Other IPS versions include the following technologies:
Super TFT (IPS) for a wide viewing angle
Super-IPS (S-IPS) for color shift free and an improvement on pixel refresh timing
Advanced Super-IPS (AS-IPS) for high transmittance
Enhanced IPS (E-IPS) for an enhanced diagonal viewing angle and reductions in response time
Horizontal IPS (H-IPS) for an improved contrast ratio and an Advanced True White polarizing film that creates a more natural color of white
Professional IPS (P-IPS) for truer color depth
To help determine if IPS is best for your computing needs, first you’ll need to understand the display technology TFT LCD. TFT LCD stands for "Thin Film Transistor" and "Liquid Crystal Display." LCD uses polarizing material and liquid crystals to form a display. TFT LCDs, also known as “active matrix,” were developed as a variant of LCD. TFT LCDs improved the color, contrast and response times of passive matrix LCDs.
The two most common types of TFT LCDs are IPS TFT LC and TN TFT LCD. TN generally has a faster response time, which provides better entertainment experiences for watching sports or gaming, but IPS was designed to solve TN display flaws, such as a poor viewing angle and low-quality color reproduction. If you use your laptop or smartphone for creative purposes, to watch movies, video chat or upload photo albums, you’ll want an IPS for the best viewing angles and color accuracy.
LCD stands for Liquid Crystal Display. It’s a thin screen type that formulates a bright panel display using two layers of polarized panels and a liquid crystal solution. Light projects through the liquid crystals to produce an image, yet because the liquid crystals are unlit, they need a backlight.
TFT LCDs (also known as active matrix LCDs) were developed to produce greater color, contrast and response times in LCD displays. The two most common types of TFT LCDs include TN TFT LCDs (standard non-IPS) and IPS TFT LCDs. A monitor with an IPS display provides enhanced features, such as optimal viewing angles, color accuracy, invariable color reproduction and better power consumption. In summary, IPS is a variant of TFT LCDs that improves upon technological limitations within TN panels that have been flawed by poor viewing angles and color reproduction.
