What is TFT LCD display and IPS LCD display?

TFT displays usually use TN-type liquid crystal technology. TFT LCDS are also classified as active matrix LCDS. TFT LCDS have capacitors and transistors. These two elements play a key role in ensuring that TFT displays operate with very little energy and do not stop running. Usually, when we say TFT LCD panels or TFT screens, we mean that they are TN (Twisted Nematic) type TFT displays or TN panels, or TN screen technology. TFT has a wider viewing Angle and better contrast than TN displays.

TFT display technology has been widely used in computer monitors, notebook computers, medical monitors, industrial monitors, ATMs, points of sale and so on.

IPS technology is a TFT display with thin-film transistors for individual pixels. But IPS displays have superior high contrast, wide viewing Angle, color reproduction, image quality and so on. IPS screens have been found in high-end applications such as Apple iphones, ipads, Samsung phones, more expensive LCDS, etc.

TFT LCD displays and IPS LCD displays are active matrix displays, neither of which can produce color, and each LCD pixel has a layer of RGB (red, green, blue) color filters that make the LCD display color. If you use a magnifying glass to look at the monitor, you will see RGB colors. With on/off and different levels of RGB brightness, we can get a variety of colors.

Neither of them can release color on their own, and both of them rely on additional light sources for display. LED backlights are usually used with them as light sources in the display module. In addition, both TFT screens and IPS screens are transmissible, requiring higher power or more expensive to see in sunlight than passive matrix LCD screens. The transmittance of IPS screens is lower than that of TFT screens, and IPS LCD screens require more power.
