Today, the ASUS Eee Pad Transformer Prime was unveiled which brought into focus a new kind of display: Super IPS+. Currently, electronic majors LG and SAMSUNG are worldwide leaders in the manufacture of display panels. LG has partnered with Philips to manufacture panels called Super IPS LCD. This is an improvement of traditional LCD panels which do not offer wide viewing angles and accurate color reproduction. Super IPS LCD panels on the other hand will produce virtually no color shift while viewing from any angle. The display technology used in Transformer Prime called Super IPS+ is mostly similar to the Super IPS panel except that the maximum brightness that the device is capable of, has been tremendously improved. LG also uses a technology called NOVA display inside it's smartphones like 'Optimus Black'. The USP of the NOVA display too is brightness. In fact, the NOVA display makes the 'Optimus Black' display panel one of the brightest panels used in smartphones till date. Samsung offers a competitor to the Super IPS panel by the name: Super PLS (Plane-to-Line Switching). These are also touted as an improvement over the traditional IPS panels. Samsung quotes these displays as cost effective to manufacture while offering improved image quality. So, in conclusion smartphones can be classified into different categories based on 3 parameters.
- Quality
- Resolution
- Brightness
Based on Quality they are divided into following common categories (Not an exhaustive list)
- LCD
- LED
- AMOLED
- Super AMOLED
- Super AMOLED plus
- TFT LCD
- IPS LCD
- Super IPS
- Super PLS
- Super LCD
Based on Resolution they are divided into following common categories (Not an exhaustive list)
- QVGA (320*240)
- HVGA (480*320)
- nHD (640*360)
- VGA (640*480)
- WVGA (800*480)
- FWVGA (854*480)
- qHD (960*540)
- Retina Display (960*640)
- HD (1280 * 720)
- WXGA (1280*768 | 1280*800)
Based on Brightness they are divided into following common categories (Not an exhaustive list)
- Nova Display
- Super IPS+
Note:
qHD stands for Quarter-HD (960*540). So, HD display should have actually had a resolution of (1920*1080), but smartphone panels having a resolution of (1280*720) are also being called HD, which I opine are being called so, based on the pixel density.
So, while checking out the display panel of the device you are about to buy, make sure that it is of the best quality and the best resolution while the cost of the device is in your budget. Currently, the following smartphone devices are the best in the market which have great panels
- Samsung Galaxy Nexus (4.65 inch screen)
- A combination of great quality (Super AMOLED) and high resolution (1280*720)
- Samsung Galaxy Note (5.3 inch screen)
- A combination of great quality (Super AMOLED) and high resolution (1280*800)
- HTC Rezound (4.3 inch screen)
- A combination of good quality (Super LCD) and high resolution (1280*720)
So.. the choice is yours..!!
Update
A smartphone codenamed 'Edge' by HTC has leaked and according to the leaked specs, it will be sporting a display panel known by the name of S-LCD 2. It is probably going to be an upgrade over the existing S-LCD panels used by HTC. The device is supposed to have an optically laminated display. In most of the smartphones, there is a slight gap between the screen and the covering glass. Normally there are chances for dust to creep in this gap. In an optically laminated display, there is no gap and the icons will just appear to float beneath the glass. This device is supposed to come out in Q1 2012. So if you are planning to wait, you have a good reason now. :)
