LED backlights have many advantages over CCFL including requiring half the power consumption and, more importantly, they are free of mercury, a toxic material that is emitted by electronic equipment. CCFL technology is in the process of being replaced by LED (light emitting diode) backlights. Up until now, these panels have used CCFL (cold cathode fluorescent lamp) back lights. That technology has gradually given way to LCD panels. In the 1990s, high-end CRT (cathode ray tube) monitors were considered to be state of the art. Important characteristics to consider when selecting a monitor to use for image editing: Illumination type – backlit fluorescent or LED The newest technology is a new form of flat panel that uses LED light behind the screen. They have been replaced by LCD flat panel monitors. The old-school CRT monitors are pretty much out of service. The best systems are precision engineered for added fidelity and evenness across the screen. Like high-end stereo speakers, the monitor is a place where you really do get what you pay for. The differences between the colors the monitor displays in its native state and the true colors of the patches are used to create a monitor profile which will cause the monitor to display the true colors more closely than it did in its native state. The color patches are measured by the puck as they are displayed. Profiling is the process of measuring the imperfections in the monitor, and creating a "filter" that compensates for those imperfections. Using the parameters set in the calibration step, profiling requires using a hardware device, often referred to as a "puck" (a Colorimeter or Spectrophotometer), that hangs over the monitor screen and reads several sets of red, green, blue and grey patches generated by the profiling software. Once it's been neutralized as well as the monitor's controls allow, it's time to measure the color and help to perfect it with software. It includes settings for luminance, white point and gamma. CalibrationĬalibration is the process of setting the monitor to the desired neutral output. This process makes the device show as accurate an image as possible.
To address this problem, monitors can be calibrated and profiled. If you don't calibrate and profile your monitor, then your picture's appearance can vary widely from the way it would look on other monitors, and can mislead you about the actual colors in your image.

The monitor is your window to the world (or at least to your photos). If you've ever been in a television store and looked at a row of sets playing the same program, you may have noticed that the color appearance can vary widely (or wildly) from TV to TV.
