IPS-Pro: Panasonic: Solely for LCD TV markets and known as IPS Alpha Technology Ltd. [26] Panasonic, Hitachi, Toshiba H-IPS & P-IPS: LG Display: They also produce other type of TFT panels such as TN for OEM markets such as mobile, monitor, automotive, portable AV and industrial panels. LG, Philips, BenQ S-IPS: Hannstar: Chunghwa Picture Tubes ...
IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces.The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane).
When no image is displayed, different arrangements are used. For this purpose, TN LCDs are operated between parallel polarizers, whereas IPS LCDs feature crossed polarizers. In many applications IPS LCDs have replaced TN LCDs, particularly in smartphones. Both the liquid crystal material and the alignment layer material contain ionic compounds ...
As of 2025, the term "AMLCD" is uncommon as a matter of technical jargon; instead, due to their ubiquity, different types of active-matrix liquid crystal displays are usually specified — TFT LCD, IPS LCD, MicroLED, and QLED are but just a few examples.
The following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies. These are the most often used technologies for television and computer displays.
Different display technologies have vastly different temporal characteristics, leading to perceptual differences of motion, flicker, etc. Sketch of some common display technologies' temporal behaviour
The operation of TN, VA and IPS-LCDs can be summarized as follows: a well aligned LC configuration is deformed by an applied electric field,; this deformation changes the orientation of the local LC optical axis with respect to the direction of light propagation through the LC layer,
More specifically, the use of polycrystalline silicon in thin-film transistors (LTPS-TFT) has high potential for large-scale production of electronic devices like flat panel LCD displays or image sensors. [1] LTPS is polycrystalline silicon that has been synthesized at ~650 °C and lower, compared to traditional methods (above 900 °C).
