TV brands like Samsung, Sony, and LG use both IPS and VA panels depending on the series. Here's how these panel types affect picture quality.
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,
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).
IPS displays belong to the LCD panel family screen types. The other two types are VA and TN. Before LG Enhanced IPS was introduced in 2001 by Hitachi as 17" monitor in Market, the additional transistors resulted in blocking more transmission area, thus requiring a brighter backlight and consuming more power, making this type of display less ...
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 figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale.
These improvements came at the cost of a higher response time, initially about 50 ms. IPS panels were also extremely expensive. Super-IPS: S-IPS: 1998: Color shift free: 100/137: IPS has since been superseded by S-IPS (Super-IPS, Hitachi in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing ...
High altitude pressure difference may cause poor function or buzzing noises [43] Can have poor brightness, especially when most of the picture is white [10] Electro-magnetic radiation emission Can emit a small amount of X-ray radiation. Only emits non-ionizing radiation. [44] Emits strong radio frequency electromagnetic radiation [45]
