Watching Laptop configuration, I get confused in the display category ? I could not figure out whether they are providing an LCD panel or LED panel.What we have came across is LCD, CCFL, LED, TN, IPS panel.
But Most of them have this type of contains in the display category

1. LCD panel in LED backlight
2. HD WLED True-Life
3. FHD EWV LED Backlight/Wide View Angle
4. Full HD 3D(1920x1080 120Hz) LED Backlight
....
Some even dont mention what type of panel they provide in laptop configuration. :annoyed:

What is LED backlight ? Is it some enhanced LCD panel or it is a LED panel?
Can anybody ellaborate it?
 
1,2,3 &4 are all basically the same. They are LCD panels with LED backlighting. There is no difference in that regard and there is no "true LED" laptop screen out there. CCFL backlit LCD panels are no more used in laptops, all new laptops use LED backlighting technology.

TN, IPS, VA are types of LCD panels. TN panels are the cheapest and have good response times but have poor viewing angles. IPS panels have great viewing angles and colors but are not as good when it comes to motion response as TN panels.

I guess that's al you wanted to know, if you still have any doubt let me know :)

Can u detailed what is the LED backlighting technology ? What type of panel are they using if it is no "true LED" as you have quoted?
 
LED backlighting simply means using tiny LEDs to provide backlight to the LCD panel instead of CCFL bulbs. The actual panels, as I said are TN LCD mostly. There are differences between TN panels also, though most TN panels are quite poor especially the 1366x768 panels. The FHD TN panels are quite good and have very high contrast ratio and good brightness as well as very high color accuracy (eg Vaio Z, Dell XPS 15 B+RG, Lenovo W510).

But still even these screens don't have great viewing angles.

IPS panels are rare. Some of the laptops that use IPS LCD include Sony Vaio SE/S15, HP Envy 15 Radiance, HP Elitebook Dreamcolor/2/3, Macbook Retina 15" etc.

PLS screens are also variants of IPS LCD used by Samsung in its Series 9 laptops.



And no.4 screen in your post is the OCB LCD panel of the Sony Vaio F 3D. It's the only 120hz (240hz Motion Interpolation) 3D laptop panel which combines the major qualities of TN and IPS panels. It has ultra sharp response times coupled with wide viewing angles similar to IPS. This technology was developed by Toshiba aimed at recreating CRT picture quality in an LCD panel. The F 3D was the only laptop to have this panel.

So yes basically these are the LCD panels used in laptops. TN, IPS and OCB.

LED TV is a total gimmick coined by TV manufacturers. All these are LCD and where they differ is in the backlighting. An LCD panel in its own cannot display image without a backlight. In older LCD TVs CCFL was used. Later they started to use LED for backlighting and used the false name LED TV. Even in LED technology there are two important methods of backlighting called edge lit and full array. Full array is better. I think all the current laptop panels are LED backlit. TN, IPS etc. are different LCD technologies. TN is low cost and is commonly used in computer displays.
 
Got it! so its all marketing gimmick! :scared14::scared14:
Basically all this stuffs are LCD with some enhancement that has something to do with LED backlighting. :annoyed:
Tys! randomuser111 and welcome baijuxavor to TE!
Tys for info, this reminds me only one thing "All that glitters are not Gold". :23:

Yes that's true. "LED" is just marketing gimmick but in laptops they don't really claim its a LED screen but LED-backlit. Whereas in the TV business they do false advertise saying its LED TV. LOL

Anyway a true LED screen is not feasibly on a laptop as it costs a lot. Be it a full array Local Dimming LED LCD or OLED.
