They are all around us -- in laptop computers, digital clocks and watches, microwave ovens, CD players and many other electronic devices. From the wrist watch and pocket calculator to an advanced VGA computer screen, the liquid crystal display has evolved into an important and versatile interface. A liquid crystal display consists of an array of tiny segments (called pixels) that can be manipulated to present information. This basic idea is common to all displays,...

...TERM PAPER Topic:LCD (LIQUED CRYSTAL DISPLAY) DOA: 22/02/2010 DOS: 06/05/2010 Submitted to: Submitted by: Bindu ABSTRACT LCD projectors are becoming smaller and less expensive, and are starting to incorporate built-in light sources and speakers. LCD panels are also improving in resolution and response. An LCD panel is fairly light and thin, but require a separate overhead projector. The LCD projector contains its own light source, so no overhead projector is required. These have more multimedia features than LCD panels, and usually include speakers and multiple inputs and outputs. Polysilicone LCDs are smaller, and allow more light to pass through than thin-film transistor LCDs. LCD projectors typically weigh between 10 to 50 pounds. Heavier ones are also available that can achieve movie screen quality, although these are more costly, and better suited to permanent installations. Most LCD panel devices have a screen of between 8.4 and 10.4 inches diagonally. A good panel or projector will also provide on-screen adjustment, remote control and a hard shell carrying case.

...AVR and monitor. Monitors in this year are modern it upgrade like computer. Brief history of a monitor The video display terminal, or VDT, marked the early days of computer monitors. These VDTs included a screen and attached keyboard linked to a larger computer by a serial connection. Because VDTs required a connection to a larger computer, they were often referred to as "dumb terminals." Dumb terminals displayed text only in two colors, usually black and green. The Apple II and first game machines began using a television CRT. IBM's CRT The ssssst of its new PS/2 computer system. The display technology allowed for 256 different colors and 640 x 480 resolutions. Despite the appearance of newer display techniques, VGA has become a computer monitor standard. Indeed, the VGA may have become the impetus for the modern computer gaming industry as the increased color palette made graphics possible. Up to this point, computer displays were limited to text. RESEARCH Types of Monitors A cathode ray tube or CRT CRT technology, computer monitors continue to be referred to as "The Tube". A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screenful of images. A Liquid crystal display (LCD) is...

...Introduction to Computers A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data without human aid (Hillstrom & Hillstrom, 2002). Computing devices are made up of many distinct electronic components that all function as one in order to complete useful tasks. All PCs are made up of many different individual components, which can be mixed and matched in millions of different configurations. This allows people to customize their PC to meet their exact needs. In this paper we will discuss and identify the major components that make a computer function. The motherboard is the spine of the computer. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. It connects all the other components of a PC together. The motherboard holds the CPU, RAM modules and most of the circuitry (What are the Computer Parts?, 2008). Adapter cards also plug into your motherboard. There are two major types of motherboards: integrated and nonintegrated. On a nonintegrated system board each major assembly is installed in the computer as an expansion card (Doctor, Dulaney, & Skandier, 2007). This includes video cards, disk controllers, and other accessories. On an integrated system board most of the components are integrated into the motherboard circuitry. Most motherboards now a day are integrated. These boards were designed for simplicity. You don’t have to...

Finally, we like to thank our classmates for their support and encouragement throughout our study. With Best Regards Introduction LCD televisions produce a black and colored image by selectively filtering a white light. The light is typically provided by a series of cold cathode fluorescent lamps (CCFLs) at the back of the screen, although some displays use white or colored LEDs instead. Millions of individual LCD shutters arranged in a grid, open and close to allow a metered amount of the white light through. Each shutter is paired with a colored filter to remove all but the red, green or blue (RGB) portion of the light from the original white source. Each shutter–filter pair forms a single sub-pixel. The sub-pixels are so small that when the display is viewed from even a short distance, the individual colors blend together to produce a single spot of color, a pixel. The shade of color is controlled by changing the relative intensity of the light passing through the sub-pixels. Liquid crystals encompass a wide range of (typically) rod-shaped polymers that naturally form into thin, ordered layers, as opposed to the more random alignment of a...

...single day. It has many parts like hardware which are touchable and software which are untouchable. Computer users may use a scoring system of evaluation when there are several competing proposals for a hardware or software acquisition. They give each evaluation factor a certain number of maximum possible points. Then they assign each competing proposal points for each factor, depending on how well it meets the specifications of the computer user. Scoring each evaluation factor for several proposals helps organize and document the evaluation process. It also spotlights the strengths and weaknesses of each proposal. Computer Hardware 1.0 Monitor Multiple technologies have been used for computer monitors. Until the 21st century most used cathode ray tubes but they have largely...

...Chapter1 ------------------------------------------------- Introduction RFID is an acronym for Radio Frequency Identification. In general terms, RFID is a means of identifying a person or object using a radio frequency transmission. In other words RFID is an electronic method of exchanging data over radio frequency waves. The technology can be used to identify, track, sort or detect a wide variety of objects. In this project RFID is used for the Tracking purpose for stolen things. An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few predefined tasks, usually with very specific requirements. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced, benefiting from economies of scale. Security over the years has been a source of concern to organizations and companies. This has caused quite a significant amount of capital being budgeted for improvements on security systems, simply because it has been discovered that the access control system mechanism is an important part of an organization. One of the important security systems in building, vehicle security is door access control. The door access control is a physical security that assures the security of a building or vehicle...
