It is true we live in a technologically-sophisticated world. But buying the right TV for your home might put your brain into a more sophisticated thinking. And most times times consumers give up and go for anything in the market.

Modern television technology is so vast and full of acronyms and jargons to promote and explain their features. All these throw the consumers off balance. They give up on knowing because they simply cant just understand the many jargons.

In this post, I will be taking you through the different types of TVs, focusing on the modern TVs such as the LCD, LED, Plasma and OLED.


CRT TV

We often refer to this as the box television. Their fall began in this 21st century due to the introduction of smaller LCD screens. Though it’s not the first TV but it is definitely in the modern TV lineage. It is called the Cathode Ray Tube TV. The reason it’s so bulky is because the box houses a phosphorescent screen and a electron gun. An image is created by firing electrons through this ‘gun’ onto a screen, exciting the particles on it to display images.


LCD TV

LCD TV make use of liquid crystal display (LCD) panel to control where light is displayed on your screen. When an electric current is passes through the liquid, it causes the crystals to align so that light can or cannot pass pass through.

LCD crystals do not produce their own light, so an external light source like a florescent bulb called Cold Cathode Fluorescent Lamps (CCFLs) is needed to create an image. CCFLs provide backlighting to illuminate LCD screen.

LCD consumes more power and its local dimming feature causes the fluorescent tubes to light the entire screen evenly, so there is no way to vary the backlighting intensity in different parts of the screen. Contrast and black levels is not better assured in LCDs, as they are not great at blocking out all the light coming from the backlight, making it extremely difficult to pull off an image well. However, they are economical to purchase.



LED TV

LED TV is not a technology, rather an updated version of the LCD generation. LED use the same technology as an LCD as both make use of liquid crystal display, but LED TV is being illuminated by an array of light emitting diodes (LEDs) instead of the CCFLs. The LEDs are smaller in size and far more efficient which gives them a few advantages like being made to be thinner. Most LED TVs measure under an inch because they add very little depth to the display profile.

LEDs consumes less power and the most important difference between LCD and LED is called local dimming- a selective lighting technique that allows for deeper blacks and better overall picture. As LCD fluorescent tubes results in poor black levels and contrast, LED offers a solution to this with their local dimming technique.

The idea of local dimming is to control the output of light emitting diodes so that the TV can shut off all the lights it does not need and just use the right ones, instead of being on full brightness all the time. This attribute makes much better black levels and contrast and as a result pulling off a good image.

However, it should be noted that not all LED TVs come fully equipped with local dimming. Infact, this local dimming divided LED TVs into two: edge-lit and full-array LED TVs.

Full-array LED displays are backlit by an array of LEDs directly behind the screen, which enables focused lighting areas resulting in more effective brightness and darkness. Full-arrat LED TVs pull of better local dimming which can compete with plasma TVs.

Edge-lit LED as the name suggest have lights set around the television frame. Edge-lit models reflect light into the centre of the monitor. They are the thinnest and lightest models available, since they have fewer lights in the centre of the screen.

Therefore, ensure to know whether it is full-array or edge-lit LED TV you are buying before you conclude on payment plans.

LED is the most popular format of TV on the market now due to its cost, size and versatility, although it is not the highest quality image available.

Well, if you can afford an LED-backlit HDTV, then go for it. They are thin, easy to mount, consumes less energy and produce great picture quality. Remember that it comes at a higher price too.



PLASMA TV

Plasma screens are made of 2 sheets of glass with a mixtures of gases stored between the layers. These gases are injected and sealed in plasma form during the manufacturing process, hence why we have the name ‘Plasma TV’.

The basic idea of a plasma display is to illuminate tiny, coloured fluorescent lights to form an image. Each pixel is made up of three fluorescent lights- a red light, a green and a blue light.

Plasma, is arguably superior to LCD & LED in terms of contrast and colour accuracy. They consume more electricity and are on larger screen sizes, usually 40”+. The cinematic experience they offer could be similar to the LED TV and for not much money.


OLED TV

OLED is a major advancement in the screen technology. However, do not mind the name. OLED is not in any way connected to LED or LCD technology.

OLED stands for Organic Light Emitting Diode and uses organic material like carbon to create light when electricity is supplied to it. Secondly, OLED TV does not require any backlight to illuminate the set, which can make the OLED screen to be super thin and significantly flexible.

What separates OLEDs from LCD/LED displays is that the pixels of OLEDs produce their own light, and so when they need to be black they are completely turned off, rather than relying on the backlight to turn off on their behalf, resulting in a much better colour and contrast.

On the whole, OLED is thinner, more flexible, faster at processing images, creates deeper colours and more crisp in contrast. It is, however, still very expensive.

Can OLED do 3D

Though 3D might have lost its initial allure it once had, but manufacturers are still interested in incorporating the feature in their high-end models. In most cases, 3D comes in passive variety which means cheaper glasses and less screen glow. This might drop the resolution you will experience. However, with the OLED sets now featuring an Ultra HD 4K display, the poor resolution has been taken care of.

So, grasping these few information, it will now depend on what you will want and what your pocket can afford.

Thanks op

Nice info! I've been mixing them up all these while

Hmmm Na Plasma sure pass be dat

Our mods, this thread deserves attention. @lalasticlala,

oyinbo no go finish person chai

LOL. with Plasma.... be sure to pay high electricity bills because they are really power hungry.....and they rare come in inches that will be moderate for our home.

lmao Na gamer I be give me that plasma for my ps4 baby!! Make I go dash my brother that LED

Tnx ops

lalasticala front page pls

Front page for Sure.

Watching with my VR kit, hoping it makes fp.




I remember back in days, my dad had a CRT TV, that required a slap from behind, before the images align.....

This was in the late 80s

Thank you

Nice info
