LCD Vs. LED TV: What’s The Difference Between The Two?
LCD TVs or liquid-crystal-display televisions selectively filter white light to produce black and colored images. The light is irradiated by cold cathode fluorescent lamps (CCFL) at the back of the LCD screen which is made of liquid crystals. LCD shutters combined with colored filters are arranged in a grid to allow a controlled amount of white light through, and to remove all but red, green or blue (RGB) portions of the light from the original white light source. Color shades are controlled by changing the relative intensity of the light passing through the sub-pixels formed by the delete fashion nova account shutter and filter pairs.
LED television is actually LCD TV that use LED backlighting technology instead of CCFL backlighting. It is for this reason that LED TVs are also known as LED-backlit LCD TVs. LED backlighting use light-emitting diodes (LEDs) to illuminate the screen which is similar to the screen used in LCD. LEDs consume less energy than CCFL, making these TVs more energy-efficient and eco-friendly compared to LCD TVs.
Further comparison between LCD vs. LED TVs is factored out in terms of brightness, black level, contrast ratio, viewing angle, cost and screen uniformity. An LED screen has better brightness than an LCD screen since the brightest panel is used in the LED television. LED screen also has better black level and contrast ratio than the LCD TV, and provides more realistic and vivid images than the LCD. Some LED televisions use an advanced local dimming technology to display images with higher resolution and better quality than the existing LCD. Both LCD and LED technology do not go well when it comes to viewing angle. A viewer cannot appreciate the high-quality images offered by LCD and LED TVs when the viewer is not directly in front the LCD or LED screen. Recent developments have introduced In-Plane Switching (IPS) LCD and LED televisions to provide better viewing angle. In terms of cost, LCD TV is more affordable than LED TV. LED televisions are usually offered as high-end products of most television manufacturing companies. When it comes to screen uniformity, LCD and LED have their own issues. But then, most viewers are not really affected by the screen uniformity of the LCD or LED TV.
To conclude this LCD vs. LED TV discussion: both LCD and LED perform better in bright rooms, and are more energy efficient compared to plasma TVs. The LCD screens used in LCD and LED TVs don’t experience burn-in, making them better in gaming, showing static images or connecting to a personal computer.
