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,
A bright dot defect or hot pixel is a group of three sub-pixels (one pixel) all of whose transistors are "off" for TN panels or stuck "on" for MVA and PVA panels. [2] This allows all light to pass through to the RGB layer, creating a bright pixel that is always on.
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). The molecules are reoriented by an applied electric field, while remaining ...
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 ...

In-plane switching (IPS) was developed by Hitachi in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time. [15] [16] Its name comes from the main difference from TN panels, that the crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of ...
Last year was the planet’s hottest in recorded history, multiple government agencies announced Friday, marking two years in a row that global temperatures have shattered records. Scientists with ...
The more stressed I get, the more I clean up around the house. I can't help it! With clutter, dirt and grime out of the way, I feel calm and in control.
