Why led tv

Compared to what had gone before, LCD TVs were lighter, thinner, brighter, more colourful and cheaper to produce, but early examples in particular regularly struggled to produce deep blacks and convincing contrast. These days, though, there are lots of very good LCD-based TVs around and many represent exceptionally good value the Samsung UE49RU is one of the best performance-per-pound televisions you can currently buy , but there's no denying that OLED is better.

How to clean your TV screen without damaging it — and which cleaners to avoid. You might feel like you need to be a tech pro just to watch your favourite TV show in the evening or enjoy a game with your friend. The two might seem similar in name, but they are worlds apart.

The reason for the switch lies in the innumerable benefits LED screens offer. The main difference between an LED and LCD monitor comes from the display technology used to create the picture displayed. LCD technology revolutionized monitors by using cold cathode fluorescent lamps for backlighting to create the picture displayed on the screen. A cold cathode fluorescent lamp CCFL is a tiny fluorescent bulb. LED monitors took the old technology a step further by replacing the fluorescent bulbs with LED backlight technology.

And OLED organic light-emitting diode technology improves it even further by eliminating the need for backlighting. However, monitors have changed since then. This turns a single monitor into a modular assortment of countless light-emitting diodes. Additionally, this expands how big the monitor can be without blowing up the cost exponentially.

The quality of direct-view LED screens is measured by pixel pitch. The pixel pitch is the distance between two adjacent LEDs on the display. The smaller the pixel pitch, the better the quality of the image. Let us go through these factors one by one and understand which technology wins in each criterion:. The difference in power consumption increases as the size of the display increases.

Light-emitting diodes are considerably smaller than fluorescent lamps used in LCD monitors. Fluorescent lamps have a considerable thickness, but the thickness of diodes is next to none.

However, direct-view LEDs offer a better angle for viewing than LCDs as the light source is evenly spread on the screen.
