It consists of two polarizing filters with a liquid crystal solution between them. An electronic current aligns the crystals so that light can either pass through or not pass through. The effect of light passing through in certain areas and not in others is what creates the image. LCD comes in two forms, active matrix and passive matrix. Active matrix is sometimes called thin film transistor (TFT). TFT allows each pixel to be controlled, which creates very sharp color images. Passive matrix is less expensive than active matrix but does not provide the same level of image control. Passive matrix is not commonly used in laptops.]]> 2018-09-05 15:17:26 UTC https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278026262 owenott_student20 https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278027506 A light-emitting diode (LED) display is an LCD display that uses LED backlighting to light the display. LED has lower power consumption than standard LCD backlighting, allows the panel to be thinner, lighter, brighter, and display better contrast.]]> 2018-09-05 15:19:25 UTC https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278027506 owenott_student20 https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278027961 An organic LED display uses a layer of organic material that responds to electrical stimulus to emit light. This process allows each pixel to light individually, resulting in much deeper black levels than LED. OLED displays are also thinner and lighter than LED displays.]]> 2018-09-05 15:20:05 UTC https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278027961 owenott_student20 https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278028228 Plasma displays are another type of flat panel monitor that can achieve high levels of brightness, deep black levels, and a very wide range of colors. Plasma displays can be created in sizes of up to 150 inches (381 cm) or more. Plasma displays get their name from the use of tiny cells of ionized gas that light up when stimulated by electricity.]]> 2018-09-05 15:20:32 UTC https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278028228 owenott_student20 https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278028874 Digital Light Processing (DLP) is a projection technology. DLP projectors use a spinning color wheel with a microprocessor-controlled array of mirrors called a digital micromirror device (DMD). Each mirror corresponds to a specific pixel. Each mirror reflects light toward or away from the projector optics. This creates a monochromatic image of up to 1024 shades of gray in between white and black. The color wheel then adds the color data to complete the projected color image.]]> 2018-09-05 15:21:40 UTC https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278028874 owenott_student20 https://padlet.com/owenott_student20/y6l1kfh8cq3x/wish/278029342 Output devices for audio signals.
