Nowadays, consumers have a lot of difficulty deciding which television set or home theater to buy among the many available varieties such as LCD, Plasma, OLED, LED, laser televisions and DLP. You have probably found yourself in a similar situation and wondered which is better than the other. In most cases, the confusion arises when it comes to choosing between LED TV and LCD TV. Basically, despite having different names, the two are not so different. A LED TV is a just a newer model of LCD TV. LED TVs are LCD TVs that are LED-backlit and people just simplify it by calling it LED TV.
LED TV vs LCD TV
Both kinds of TV use liquid crystal display (LCD) panel to regulate where light will be displayed on your screen. The mechanism with which they pass light comprises of two layers of polarizing material that has a liquid crystal solution held between them which align when an electric current passes between the liquid substance and allows light to pass through. This way, every crystal acts as a shutter and either allows light to go through or blocks it out.
From the above explanation, we can rightly deduce that both LED and LCD TVs make use of the LCD technology and the main difference between the two is backlighting. LCD TVs make use of cold cathode fluorescent lamps for backlighting while LED TVs utilize many tiny light emitting diodes LED’s to light the screen which are more efficient and has several other benefits that make it superior than LCD TVs. These advantages include:
- They consume less power than LCD because it has a local dimming feature which is a technique that selects light and provides deeper blacks and high quality pictures. The disadvantage of LCD’s backlighting technology is that it is difficult to control the backlighting strength in different sections of the screen because the fluorescent tubes must illuminate the screen evenly. In LED TVs, this problem is off-set by local diming. This technology makes it possible regulate the output of LEDs by dimming and turning off brightness instead of leaving it at full brightness every time. The diming features enables the TV to display contrast well and hence show clear and sharp images. However, it is worthy to note that not all LED TVs have this feature, rather, they come in two variations which are full-array and edge-lit. Full-arrays are the ones that have local diming abilities hence making them the better choice than edge-lit ones.
- LED TVs are also smaller than their LCD counterparts. This makes them light and compact.
- They also have a great viewing angle and glare and adds depth.
- LED TVs also usually come with a Game Mode and are believed to be more long lasting as compared to CFL fluorescent enabled backlighting which changes color and white balance over time.
