The influx of technology has its mark on almost every aspect of our lives. From our professional lives at work to the way we spend our leisure time at home. We can even see people sitting in a restaurant waiting for the meal to arrive with a Smartphone in their hands.
This flood of technology is also continuously upgrading the conventional appliances that were being used by us since decades. Television is one of them; and we can see an uninterrupted up-gradation in its technology in recent years. Now, households want to possess the best screen in their TV lounge to enjoy to the fullest.
The conventional TV screens were replaced by Plasma TVs, LCDs, LEDs and now by Smart LEDs geared with internet connectivity, smart sharing, a front camera and what-not.
The race is still not over yet and 3D LEDs have added another dimension to this technology war. We can see all the big electronics brands like Sony, Samsung, LG, Haier, Panasonic, Toshiba etc. trying to take the lead in this competition.
Choosing which TV technology to buy is a difficult decision as each has their own set of pros and cons. So, let us make a quick analysis of their working mechanism and have a quick look at the pros and cons.
Working Mechanisms:
Plasma TVs
Plasma display works by illuminating small, coloured fluorescent lights to create an image. It has a matrix of small gas cells packed in two sheets of glass. Every cell acts as a tiny fluorescent tube that releases UV light that hits red, green and blue spots and create image.
LCD TVs
LCD TVs work on the mechanism of Liquid Crystal Display. The panel is made of an array of tiny, coloured liquid crystals. It works when light from behind the screen shines on these crystals and the amount of light emitted by each of them is controlled by signals. Picture is built through this method.
LED TVs
LED TVs work on the mechanism if Light Emitting Diodes. The mechanism is almost the same as other TVs but instead of lighting it up by back light (like LCDs) it is replaced by light emitting diodes as a source of light.
LEDs commonly have 2 types
- Edge lit (LEDs lamps placed at the edges of the screen)
- Back lit (LED lamps on the back of screen)
Comparison:
Let us now have a comparison of all three types for a better understanding.
Criteria | PLASMA | LCD | LED |
Thickness | Minimum 1.2 inches | Minimum 1 inch | Less than 1 inch |
Power Consumption | More than LCD | Less than Plasma | Least |
Life expectancy approx | 20,000 – 60,000 hours | 50,000 – 100,000 hours | Around 100,000 hours |
Price | Moderate | Moderate | High |
Contrast Ratio | High | Medium | Very High |
Typ. Brightness | 1000++ cd/m2 | 700 cd/m2 | 600 cd/m2 |
Burn-in | Yes | No+ | No |
Viewing Angle | 170deg | 160+deg | 160+deg |
Fully Digital Display | Yes | Yes | Yes |
Refresh Rate | < 8ms | < 12ms | < 6ms |
Max Resolution | 1080p | 1080p | 1080p* |
Weight (lbs) | Medium | Light | Lightest |
Set Depth | 3 – 7” | 2”+ | <1-2” |
Screen Size | < 103” | 82” | <10” |
Power Consumption | Medium | Low | Very Low |
Pakistan Local Market
In Pakistan we can buy latest technologies in pin pack and used conditions from company’s outlets or various other online market platforms.
LEDs commonly have 2 types
Edge lit (LEDs lamps placed at the edges of the screen)
Back lit (LED lamps on the back of screen)
(Nice article bt would u define Edge lit and Back lit a bit more)
Back Lit LED TVs use LEDs behind the LCD screens to light it up
Edge Lit LED house the LEDs on the sides of the screen, their light then diffused into the screen and resulting in great colours.
Cheers!

You differentiate in a WHOLE ARTICLE, I just differentiate by “Bhai, LED k viewing angles behtar hotay hain” :P
this whole ‘article’ was a farce
Good comparison. Thanks
I am going for plasma TV instead of LED Tv after reading this article
plasma has very short life compare to LED
TV say bahir LED
Those who use “zero ka bulb” of 13 watts should replace them with LED bulbs made by our local industry.
Zero ka bulb = 13 watts, life around one month
LED bulb 30Rs = 3 watts, 3.5 years say istemal kar raha hon din raat chalta hay aik bhi kharab nahi howa
kahan say milta hai itna sasta led buld???
electronics shop say, zero bulb ka nihayat acha mutbadil
Max resolution of LED TVs is 2160p UltraHD (4K) not 1080p :p
Good plasma tv produces the best colors and pure black. But it take far more power and that is a problem in pakistan that you can’t run it on UPS. Also viewing angles are the best on plasma. LED is just catching up on these aspects but have lowest power consumption.
Which technology has the least affect on eyeside?
hello,
What a junk farce article, its close to i read nothing lol . nothing informative or new.
I bought me self a Sony 42w670a Internet LED 42″ and damn the display is gorgeous. specially when i play blu ray on it.
Explain the bloody power consumptions vice versa and explain your argument man. what a lame article.
Most of the companies have stopped producing Plasma TV’s now! You can say Plasma is taking its last breaths!
Funny comparison … Power ConsumptionMore than LCDLess than Plasma
Good Article,
in Comparison Table: Typing Error Power Consumption
Power Consumption More than LCD Less than Plasma Least
Power Consumption Medium Low Very Low
Buying a new LED TV thanks BRO! its usefull info..cuz its comfort to eyes.FAct
