Not everyone is that familiar with what we usually see at appliance centers and shopping malls every time you come across television sets that says LED and LCD’s. A lot of people end up being confused about this matter.
So is there really a difference between an LED and an LCD television or monitor? If there are any differences, what are those? In this article, let us talk about the difference between LED and LCD displays.
A lot of people nowadays upgrade their television sets, computer sets, or any displays that they consider becoming outdated to what the technological innovation offered to us right now. Upgrading this type of appliance or device involves a lot of different things, but, most of the time, it all goes down to the one big question: What type of television should you buy? You often see fancy television sets that are usually thirty to 40 inches big, but something holds you back because of the confusion between LED and LCD.
LED stands for Light-Emitting Diode (LED) which functions as a semiconductor diode that lights up or glows when there is a voltage applied to it, whereas, the LCD that stands for Liquid Crystal Display (LCD) that is a flat-panel display that is electronically modulated optical device which utilizes the light-modulating properties of the liquid crystals because it cannot emit light directly, that it needs the use of a backlight or a reflector to emit or produce images in colors or in monochrome.
Still confused? LED is actually an LCD display monitor or television, but the former is a specific type of LCD display, and because of its lengthy name which is LED-backlit LCD television, tech experts and the consumers are used to calling it LED that creates the confusion between LCD because of its reference.
Both LED and LCD displays or televisions are made based on the LCD technology, you might probably be thinking right now about the difference between the two. LCD televisions are now obsolete and are no longer being purchased by consumers because of its backlighting. LCD televisions use cold cathode fluorescent lamps or CCFL’s to provide good backlighting compared to LED displays that use a smaller and a more efficient diode that emits more light to create sharper images in the screen.
Tech brands nowadays fully use LED lights in its LCD televisions and display monitors and are now called LED televisions.
An LED display is far more advanced to its predecessor, the LCD display because it efficiently uses the illumination of the three basic forms that are used in LCD displays; which are the CCFL backlighting, the full-array LED backlighting, and the LED edge lighting. Each of the three basic illumination forms has its own important roles in providing good-quality images on the screen.
The CCFL Backlighting is the one that creates an illumination by having the same level and fairness of the colors brightness that can be maximized with the LED display while the full-array backlighting is the one that replaces the old and outdated CCFL’s for LED displays by using local dimming process where it lights the dimmed zones of the LED, and the edge lighting which implies to the edge-lit televisions along the edges of the screen, within its lighting, it can be configured into different lighting types along the bottom, the top, and the left and right positions.
