The evolution of laptops has also called for the production of convenient, ergonomic laptop accessories
Today's laptop computers. Laptops are mobile personal computers that weigh significantly less than 10 lbs. Much more capable and convenient than some of the most popular desktop computers today, laptops have developed from specialized usage to the choice for all-around computing needs. The development of LCD (liquid crystal display) technology provided the means for creating thin and clear flat panel displays in a compact computer. They can easily be combined with projectors to offer group viewing of PowerPoint presentations, for example.
What's different about notebook computers? The term laptop computer and notebook computer are used interchangeably today. During earlier evolutionary years of the technology's development, the term 'notebook' was often applied to the lightest weight and smallest units being created, but the units and terminology are now virtually the same. However, a new category has developed of "ultra-light laptops" that pack as much performance as possible into a small package, providing users with a screen size of 12" diagonal or less.

Sandwiched layers of an LCD design
Laptop displays are designed using LCD, Liquid Crystal Display, technology. The design calls for thin "sandwiches" of glass containing liquid-crystal filled cells (red, green and blue cells on color monitors ) that then make up a pixel. Each pixel (short for Picture Element) is a single point of the total picture and they are arranged in rows and columns so close they seem connected. The number of pixels a monitor can display will vary by machine and affect the resolution, clarity and brightness. One model of Apple PowerBook, for example, boast a display with over 1.7 million pixels.
Arrays of TFTs (thin film transistors) provide the voltage that cause the crystals to untwist and realign so that varying amounts of light can shine through and create images. This particular sensitivity to light makes projection equipment (such as LCD front projectors) a perfect usage for LCD technology also because of how it focuses light through LCD chips.
There are five layers to an LCD display: a back light, polarized glass sheet, colored pixel layering, coating of liquid crystal solution that responds to signals off a wired grid of x and y coordinates, followed by a second glass sheet. To create an image, electrical charges, precision coordinated in various degrees and volts, effect the orientation of the liquid crystals, opening and closing them and changing the amount of light that passes through specific colors of pixels. LCD technology has increased its accuracy, thanks to advances such as thin film transistors (TFTs, also known as active-matrix technologies) that can produce sharp and more accurate color images than earlier technologies.
Take care with your LCD screen. Unlike CRT monitors which use a thicker glass screen, the LCD screen is very sensitive to touch and should not be pressed. The pixels may be irreparably damaged making it impossible for images in that section of your screen to be viewed.
Convenient mounting of notebook computers. The portability and light weight of laptops allow them to be used for traveling as well as desktop computing. The advent of wireless internet connection offers users functional convenience just able wherever they're located. Enabling even greater access and convenience, a wide variety of mounting options are available for individual users as well as business environments. Medical and dental facilities, security stations, media studios, financial institutions, laboratories, schools, and individuals can all benefit from various mounting options
