LCD Computer Monitors vs. LED Computer Monitors: If you are looking for a computer monitor to replace your old and bulky CRT monitor, either an LCD or LED monitor is a major upgrade. If you are deciding between an LED or LCD model, there is not much difference for the regular computer user. If, however, you have to get the newest gadget on the market, get the LED because it is new. For all others, the only reason to justify the extra expense of the LED is if you are a professional in the visual arts or a gaming enthusiast. Computer animation artists, graphic designers, and video producers will enjoy more vivid colors and sharper images on the LCD monitor. You should know the differences in LCD and LED technology, and what that means to the objective specifications and your subjective viewing experience. #Liquid Crystal Diode (LCD) Monitors: An LCD monitor is one with a fluorescent panel and cold cathode technology. This type of monitor is an improvement over the older cathode ray tube (CRT) monitors, which used a vacuum tube to emit electrons onto the fluorescent panel. LCD offers improvements with almost half the power usage, a mercury-free environment, and low electromagnetic interference (EMI). Also of importance to consumers are the weight reduction and the much slimmer design of about 1/2-inch thick. Liquid crystal diode (LCD) technology is a form of lighting used in computer monitors, laptops, and televisions, along with various other forms of home and outdoor lighting. It uses cold-cathode fluorescent lights known as CFL lights to illuminate the screen for viewing graphics, text, and video. LCD contains a cold cathode and twisting crystal lights as the defining technology. #Light-Emitting Diode (LED) Monitors: Light-emitting diode (LED) computer monitors do not use cold-cathode technology and fluorescent technology. Instead, light diodes illuminate the screen in one of two different ways, or a combination of both. White LED lights are clustered around the rim of the screen and diffuse evenly, called edge lighting. LED lights are also spaced evenly behind the screen, and they are either not controlled or are controlled with a local dimming option. If you are looking for an LED monitor, look for this local dimming on/off option. #LED Advantages: The advantage of LED backlighting is an even better energy savings, the best on the market, in fact. LED also offers better color quality, clarity, and faster refresh rates. The local-dimming option found in some models allows fine tuning of color, especially in the black-and-white ranges. When the black-and-white range is clearer, it provides a better contrasts to the true colors, and therefore a more dynamic and realistic image. LED monitors offer even thinner construction than LCD monitors because of the LED lights around the edge of the panel. #Comparing LED to LCD Monitors The main difference between these two technologies is the lighting technology: cold-cathode fluorescent lighting vs. light diodes. #Resolution Bigger screens usually mean better resolution. The resolution refers to the amount of picture pixels up by the number of pixels down. Pixels are the little dots that are the smallest unit used to create the picture. More pixels equal a richer, more colorful, and clearer image. #Contrast Ratio This specification refers to the shading capabilities between black and white. A higher ratio means that color reproduction is more accurate. The LED wins here. #Brightness The measure of brightness means that the image is clear and visible especially in very bright light. LED and LCD tie here, but may differ in some manufacturer’s models. #Weight These models tie here, but LED is often lighter comparatively. Both LED and LCD monitors totally outclass bulky CRT monitors in weight. #Energy Star While LCD monitors are 40 percent more efficient than the old CRT monitors, LED monitors offer a 20 percent energy efficiency over the LCD monitors, which qualifies them for official energy savings recognition.
