LCD PROJECTIONS breakdown
LCD is acronym for ‘Liquid Crystal Display’. LCD Projector functions using the heat from the halogen bulb to convert crystals into liquids. LCD Projector Logistics The LCD video projector contains three LCD panels. At the center of the projector is a halogen bulb, which is surrounded by the panels. The panels produce light. As the halogen bulb heats up, the crystals melt and allow more light to pass through. Hence, the intensity of the halogen bulb brings about the difference in the tones. Higher the temperature of the bulb, lighter the tone and vice a versa. Images travel to the tube present inside the projector from the DVD player or the satellite box. These images in turn bounce on a screen that is coated with phosphor. Every fragment of light hitting the screen is termed pixel. On hitting the screen, the pixel breaks down into its color component that is red, blue or green. The heat produced by the halogen bulb is controlled by the voltage that flows into the LCD video projector. Considering the voltage that flows into the
projector, the 3 LCD panels can produce more than sixteen million colors. This is what enables us to view all the subtle colors of a sunset. A single panel is for a single color; meaning one panel handles all the pixels that are created by the red color, the second for blue and the third for green. The color images travel as three separate beams of light and hit the wall. Here the colors fall on each other to produce the true color.
