Everything About LCD Monitor

..continued from previous post
Viewing angle. This is the maximum screen projection angle such that display is still in its acceptable definition, neither blurry nor faint.
Color Gamut. Or the color support. How many color set can the LCD monitor display?
Luminance. Is the amount of light emitted by the LCD monitor just right? Is it too bright?
Contrast ratio. This is the luminosity ratio of the brightest color to that of the darkest color. Higher contrast ratio is more favorable than the lower.
Aspect ratio. This is the width-height ratio.
Input ports. These are usually DVI, LVDS, VGA, HDMI or S-video. This depends on your need.

We hope that the specifications we listed were of help to your evaluation.

Various computer companies has shifted its production from cathode ray tubes (CRTs) to liquid crystal display (LCDs) to meet the demands and wants of its consumers. The evolution of computer monitors brought users to a more convenient and clearer resolution of pictures, videos, and colors. Clearly, CRTs is phased out and the LCDs have dominated the computer market.

Here are some of the companies you would like to check for the type of LCD you want to have.

For LCD monitors that are meant to be used in bright sunlight or other areas with poor lighting conditions, you need a special type of screen using transreflective technology.

Transreflective monitors reflect a great amount of heat (and light) and prevent overheating. They are also helpful in industrial situations when monitors have to be read in bright sunlight but cannot be simply adjusted to face away from the sun. These screens reflect most of the sunlight the monitor is exposed to, and automatically increase or decrease the light emanating from the screen depending on how much light that shines on it, thus reducing the need for manual light adjustment.

LCD is short for liquid crystal display, a type of display that is used in digital watches and many portable computers. The LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them and when an electric current passes through the liquid, it causes the crystals to align. Each crystal is like a shutter, it either allows the light to pass through or blocks the light.

The monochrome LCD images usually appear as blue or dark gray images on top of a grayish-white background while the colored LCD displays use two basic techniques for producing color: the passive matrix (which is less expensive of the two technologies) and the thin film transistor (TFT) or active-matrix.

You can save energy using a more efficient monitor…the LCD.

Choosing an ultra high efficiency LCD monitor can reduce your energy usage, even over other LCD monitors. The ultra high efficiency monitors use up to 80% less energy than an average CRT monitor.

You can actually save 520 kWh/year by switching from your old CRT to ultra high efficiency LCD monitor or the qualifying monitor. You can even save 360 kWh/year by switching from a standard LCD monitor to ultra high efficiency LCD monitor. Qualifying monitors can also eliminate about 1000 lbs. of CO2 emissions over the lifespan of the monitor

Liquid Crystal Display(LCD) is technology that uses rod-shaped molecules (liquid crystals) that flow like liquid and bend light. Unenergized, the crystals direct light through two polarizing filters, allowing a natural background color to show but when it is energized, filters redirect the light to be absorbed in one of the polarizers, causing the dark appearance of crossed polarizers to show. The more the molecules are twisted, it produces a better contrast and viewing angle.

Since less power is needed to move molecules than to energize a light-emitting device, LCDs replaced the light-emitting diodes (LEDs) in digital watches in the 1970s. Eventually, LCDs were used for monochrome displays and still are and in the 1990s, color LCD screens caused sales of laptop computers to explode. In 2003 to date, more LCD monitors were being sold for desktop computers than the bulky and space consuming CRTs.

HiColor Technology has been successfully developed by AUO using CCFL backlights to increase color saturation by 33% as compared to conventional LCD screens. Following the latest development trend in LEDs, AUO developed HiColor using RGB LED backlights, which can reach 105% NTSC while providing natural performance of red, green and blue lights and enabling rich, bright, and vivid display colors.

AUO also developed several techniques to improve LED backlights’ image performance. For instance, Color Management eliminates artificial color caused by inconsistencies between the signal and the light source. The intensity of the RGB LEDs can be changed using the Flexible Color Temperature Setting without losing luminance. Other advantages of HiColor Technology includes instant light, mercury and lead free, low temperature start, faster response time, and vibration and shock safe.

What makes LCD display monitors different from the traditional CRT monitors is that actual screen dimensions are used to market LCD monitors. This is the screen’s displayable area, from the upper corner to the lower corner of the display. The aspect ratio of the screen is one of the more confusing parts about understanding LCD monitors. Most people are used to CRT displays, which has a 4:3 ratio of vertical to horizontal measurement. LCD screens, however, are marketed as wide screen displays, which looks at the diagonal measurement. However, its aspect ratio is still very similar to the wide screen TV’s 16:9 display. Make sure you look at the horizontal and vertical measurements as well as the aspect ratio of the LCD screen.

Organic LED’s are seen as the display technology of the future mainly because of the cost factor which is way cheaper than current display technologies. With the old and reliable CRT on its way out, slowly being replaced first by plasma and then LCD’s, the evolution of technology makes life easier and a whole lot lighter.
One of the enticing facts about OLED’s is the ability to print one out with a device as simple as your desktop printer, further processed into any shape of display that can be thought of. Read the rest of this entry »

Everybody knows how annoying a scratched computer LCD display can ruin your day or even cross your eyes, straining it too much causing headaches. Luckily, there are protective display films that can be fitted onto them to prevent such incidents. These scratches are actually on a protective acrylic sheet that sits above the actual glass screen to prevent such incidents and they can also protect you from prying eyes with special treatment that prevents viewing at an angle that would be off the front of the screen. This prevents you from getting victimized by identity thieves who sometimes prey upon unsuspecting people who uses their portsbles out of the office. Read the rest of this entry »
