LIQUID CRYSTAL DISPLAY (LCD) MONITOR BLOCK DIAGRAM



LCD or flat panel computer displays are the latest and greatest offerings in the desktop computer industry. They have been used for years in the portable and notebook computing markets, but recent developments have increase performance and size while reducing costs making them viable in the desktop environment. LCD displays are lightweight, extremely thin and use much less power than CRT based monitors.


LCD panels are used in various applications ranging from smaller portable electronic equipment to larger fixed location units. Applications such as the display device for digital watches, portable calculators, LCD Monitor and TV, laptop and notebook, arcade game machines, automobile navigation systems, industrial machine, video and digital cameras.


Life span, this is typically the time taken (viewing hours) for the average backlight to dim to 50% of their original brightness. Generally, LCD monitors last longer than CRTs. A typical LCD lifespan is 50,000 hours of use compared to 15,000 to 25,000 for a CRT. A longer monitor lifespan can provide a better return on investment.




LCD (LIQUID CRYSTAL DISPLAY) NATIVE RESOLUTIONS BASICS AND TUTORIALS


WHAT ARE LCD (LIQUID CRYSTAL DISPLAY) NATIVE RESOLUTIONS?

The physical structure of some types of displays, including LCD Monitors/TVs and plasma panels, defines how many pixels can be displayed at once.

The display produces the sharpest picture when used at its so-called native resolution. This is the physically number of horizontal and vertical pixels that make up the LCD matrix of the display.


Setting a computer display to a resolution lower than this resolution will either cause the monitor to use a reduced visible area of the screen or it will have to do extrapolation.

This extrapolation attempts to blend multiple pixels together to produce a similar image to what you would see if the monitor were to display it at the given resolution but it can result in fuzzy images.

Below are some of the common native resolutions found in LCD monitors:

14-15": 1024x768 (XGA)

17-19": 1280x1024 (SXGA)

20"+: 1600x1200 (UXGA)

19” (Widescreen): 1440x900 (WXGA+)

20” (Widescreen): 1680x1050 (WSXGA+)

24” (Widescreen): 1920x1200 (WUXGA)

30” (Widescreen): 2560x1600
