LED TV provides some special features that make them attractive to consumers. For example, they are not only slimmer but also brighter than other flat-screen televisions while they consume relatively less power. People can hang them on walls like pictures and still receive plenty of details. However, there are some important technical specifications to consider before making a purchase.
LED refers to light-emitting diode. Basically, a diode is an electrical conductor that allows current to flow in a specific direction only. When voltage is applied to a diode, it emits photons in a process known as electroluminescence. Advanced technology has made it possible for LEDs to emit significant brightness, which has led to the manufacture of different devices, including television displays.
Different types of LED TV have different features and consumers need to understand what they want. Here are some of the important LED TV technical specifications.
LED TV Technical Specifications To Look For Before Buying
Faster Refresh Rates
Refresh rate is the number of times a television renders a frame per second. Conventional televisions refresh at 60Hz, which results in blurry images during fast movements. LED televisions, on the other hand, can refresh at rates faster than 240Hz. The faster the refresh rate, the clearer the images will be.
LED TV with a local dimming feature will reduce the level of backlight in darker parts of images to allow for more details and contrast. A higher contrast ratio – the difference between black and white – generally means a better television. The ratio can range between 1000:1 and 10,000,000:1. This gives the users a better chance to adjust the display according to their personal preferences. Some televisions support widgets that display such things as pictures on a sidebar. Others also support captions.
Times are gone when every television smaller than the traditional CRT ones was considered slim. Going by the current standards, any television with a thickness of more than 4 inches does not pass the slimness test. Users who would like to hang their televisions on walls must take this seriously.
A television with more connections is more versatile because it can be connected to a wide variety of devices, including computers. High-end LED televisions have at least 4 HDMI ports, Ethernet port, USB port, Wi-Fi port and memory card slot. Such televisions can communicate with other devices both physically and wirelessly and display relevant content.
