LCD and LED Display
LCD or Liquid Crystal Display is a Flat panel Technology used in TVs and computer monitors. A LED or Light Emitting Diode is an electronic device that emits light when an electric current is passed through it. Typically, LCD has a backlight that provides light to individual pixels arranged in a rectangular grid. Though the working concept of both LCD and LED is same but LEDs have wider angle than LCD and LED delivers better accuracy in comparison to LCD. An LCD’s backlight may either be a traditional bulb or a LED light.
An “LED display” is simply an LCD screen with an LED backlight. This is different in OLED Displays where each individual LEDs light up for each pixel. While in LCDs the liquids let the light shine through even if the backlight is off. So, OLEDs have darker black levels than LCDs When compared to LEDs, LCDs are lighter and has less power consumption. And while choosing a display or a monitor, consumers prefer higher and deeper black level and contrast ratio which provides better picture quality and color accuracy. The response time is much higher in LED display than in LCDs. LED TVs and computer monitors are typically brighter and thinner than their LCD counterparts.
