Advanced Technical Terms Related to Display Devices

resIn this era of technology, mostly peoples wants to use advanced and latest thinks by which they can feel and utilize the benefit and its features. In such advanced technology, there are many terms by which allows to user to take the real time effects. In the term of high definition television or computer monitor, there are various thinks such as resolutions, panel types, refresh rates, etc. by which people feel the real things. These terms are most important in the term of quality of display device.

The term resolution in computer monitor, high definition television, laptops or other display device is the amount of individual pixels in each dimension on screen which can be shown. It can be an indistinct term, particularly as the showed resolution is controlled by various elements in CRT (cathode ray tube), flat panel display which contains liquid crystal displays, or projection displays using fixed image element arrays. It is commonly mentioned as the multiplication of display device width to its height, with the units in pixels. Let us describe it with the help of an example, “1280 × 960” means the height is 960 pixels and width is 1280 pixels.

In general, monitors and other display devices are coming in various resolution and screen size. To develop these display devices like (Liquid Cristal Display) LCD there are many panel technologies used like IPS, VA, PLS, AHVA and TN. TN (Twisted Nematic) is relevant inexpensive display which is the most common consumer display. The pixel response time on Twisted Nematic panels is adequately fast to avoid the shadow trail and ghosting items of previous production.

IPS (In-Plane Switching) was designed by Hitachi organization in 1996 to improve on view angle and color reproduction of Twisted Nematic panels in particular time. The name of IPS comes from the variations from Nematic panels. Basically, it IPS the crystal molecules move parallel to the panel plane in its place of perpendicular to it.

The next term is refresh rate, it considers the affects responsive the monitor looks and feels to the user. Most of the liquid crystal display monitor runs at 60 Hz refresh rate of under their built-in resolution. It indicates that up to 60 distinct frames of information displays in every second with a 16.66 micro second ‘gap’ between the frames. Refresh rate value can be altered, but the value must be predefined. In normal monitor, refresh rate value cannot be changed. There are some select LCD monitor which runs in their built-in resolutions at a refresh rate of 120Hz or higher in sometime.
