A machine consists of many sub systems working together to perform a certain task. The information from the electronic devices are retrieved from the machine sub systems as binary code. All this information is presented in a user readable formatthrough a display device. The display technology has seen a rapid growth in the past few decades from the old CRT (Cathode Ray Tube) displays to the presently in demand LCD (Liquid Crystal Display) and LED (Light Emitting Diode) displays. The LCDs and LEDs consists of two dimensional arrays of individual display units (pixels) whose number to size of display determines the clarity of the display (resolution). These display units which we encounter on a daily basis (LCDs and LEDs) are pixel based display systems where these individual pixels form an image by combining individual colors. The colors are formed by different intensities of the primarycolors RGB (Red, Green and Blue) or CMYK (Cyan, Magenta, Yellow and Black) combinations. But these technologies have a poor reputation when it comes to image quality, weight and power consumption when they need to be considered for application in wearable technology.
