LCD Panel Type 

LCD screens are typically based on panel type and backlighting solutions. There are three different panel type solutions available in the market: Twisted Nematic (TN), In Plane Switching (IPS) and Vertical Alignment (VA). These options of panel types provide different features, such as viewing angles, colour reproduction, response time and contrast.

TN Panels are the most established yet still the most popular technology as they provide the shortest response times, offer high brightness, use less power and are inexpensive to manufacture. Despite these advantages, it must be noted that colour shift occurs at wider viewing angles and there is also a grey inversion effect when viewing the picture from above or from the sides.

In comparison IPS Panels have noticeably improved colour reproduction and viewing angles. The drawback is their difficulty to emphasise blacks, which in turn leads to problems with the contrast. IPS Panels are also expensive and have not yet been widely adopted by the market.

VA Panels, which combine the advantages of both TN and IPS.
This solution offers good viewing angles, improved blacks and excellent contrast.
