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,

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 desirable for notebook computers.

IPS panels require up to 15% more power than TN panels. [23] IPS panels are more expensive to produce than TN panels. IPS panels have slower/longer response times than TN panels. [24] IPS panels are sometimes vulnerable to a defect called backlight bleeding.
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 ...
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
Version 1.1 was released in March 2009 and was followed by version 1.2 released in August 2011. Version 1.3 was released in June 2013 [ 1 ] and current version 2.0 was released in September 2017. DisplayID uses variable-length structures of up to 256 bytes each, which encompass all existing EDID extensions as well as new extensions for 3D ...
