LCD Displays Explained
LCD (Liquid Crystal Display) displays offer bright, high resolution images. When they were introduced, they forever changed the look, feel, and placement options previously afforded by their CRT predecessors. Their advanced technology, thin design, and lightweight made LCD displays perfect solutions for businesses looking to get their messages seen and remembered.
LCD displays require a light source to illuminate the pixels. First generation LCD displays used CCFL (Cold Cathode Fluorescent Lamps) to handle this task. CCFL backlights did a fine job of illuminating the display, but exhibited a few drawbacks. Their physical size limited the minimum depth of the overall panel; they required higher power; and had a limited life expectancy.
LEDs solved the challenges associated with CCFL. Using a LED (Light Emitting Diode) light source to illuminate the pixels, the overall panel could be thinner, while using less power. LEDs also have a much longer life expectancy. (Note: While commonly referred to as LED displays, they are actually LCD displays that use an LED light source.) Edge-Lit LED displays place the LED light source at the outer edges of the panel, and are available in many different options to suit a wide variety of installations.
Advanced touch-screen models invite personal interaction, and are perfect for interactive communication environments, such as classrooms, conference rooms and more. From conference centers to classrooms, Corporations and Schools can employ touch LCD displays to support presenters with bright, sharp video playback, and allow them to interact with the content displayed.
