Before Buying Lcd Screen
Upfront technology has become a common use in financial institutions around the globe in order to improve the quality of services offered. LCD screens are prime contributors for quality maintanance and improving the overall look and feel of various financial offices such as banks and stock market trading centers.
As exemplify by the use of LCD display at an ICICI Bank in India to showcase the bank products and to show the token number for waiting clients, all of those on the same screen. Furthermore, New York Stock Exchange is using LCD Information Display Screens to show stock information and news. The screens provide a clear, continuously updated status list of stock prices, current exchange rates and other financial information.
LCD screens are also used for security purposes in various financial institutions. In bank branches or offices, multiple LCD screens security images are seen on one large screen to give a full panoramic picture of the happening activities. But for those needs, financial institutions are usually purchasing LCD displays instead of LCD TVs.
One of the first thing to consider before purchasing a LCD screen is the screen size. For LCD screen standard, the size of the tablet is approximately the size of its visual area. That is one common thing the LCD screens have with CRT screens. For monitors in the same size, the visual area of LCD screen is larger than the one of CRT. Generally a 15-inch LCD screen is equal to a 17-inch CRT screen. Due to different purposes, the best standards or choices of one’s LCD screens may differs.
After deciding which LCD screen size is right for your office, it is important to consider the LCD display’s price. Price is always important however financial institutions are increasingly evaluating the Total Cost of Ownership. Even though LCD TVs cost less than the LCD screens, their life span can be shorter, in particular if the LCD screens is going to be operated for limited number of viewing hours. Do note that not every LCD screens are meant for 24 hours 7 days a week operation, while LCD TVs are made for a more limited viewing hours.
In the matter of resolution, the resolution of LCD screens is a fixed figure and is also called “native resolution” or “maximum resolution”. So we advised you to set your desktop resolution to the fixed figure. Otherwise it can lead to several problems like bent and blurred images, certain pixels lose or going into blanks, or the monitor will simply stretch or shrink down the image. Making it important to know the resolution of one’s LCD screen and adjust it to make the best visual effect out of it.
However, keep in mind that “the higher resolution the better LCD screen might be” is not always true. If your LCD screen’s resolution is too high, it will caused the images and characters on the LCD screen will rather look small. To make sure what the wall display best resolution is for you, try to make the resolution that is closest to the maximum resolution that can fits your eyes. It is also best if you can find maximum resolution exactly as you want.
Yet, you should know that screen size and resolution are not necessarily related, means bigger screen does not always have higher resolution. A good way to predict a screen’s resolution is to check its price. Normally, a screen with higher resolution comes with higher price.
Please not that it is also important to find out the LCD screens aspect ration. Aspect ration is the ratio of horizontal/vertical aspects of the LCD display. The CRT monitors or the old fashioned LCD displays have ration of 4:4. While the new LCD screens now have 16:9 or 16:10 ratios.
Also, take a look at the LCD display’s picture quality. Most large LCDs are High Definition. LCD screens in HD quality is known to offer better picture resolution, contrast ratio, brightness, color reproduction and fast response time which contributes in picture quality enhancement. Aside from High Definition, brightness and contrast ratio also play important parts if not vital features for the LCD screens. Especially because it is crucial LCD screens use in financial sectors to have crucial pricing information and other related details. Further, most new LCDs have 176 degree of viewing angle, making it easy to view.
Like its name, LCD (Liquid Crystal Display) screen uses the light modulating properties of liquid crystals. Liquid crystal is a kind of material with physic properties between liquid and solid which do not emit light directly. Therewith, the backlight of a LCD screen determines its brightness. In fact, the higher the brightness, the better color the display delivers. If the brightness is too low, then the color the screen delivers will be very dark and tiring to look at after a long time. In short, the lighter of the white picture and the darker of the black picture, the higher the contrast of a LCD screen.
The higher the constrast resulting to clearer and more colorful image quality, a better color laying effect of the LCD screen.
Other things that needs to be considered are the ruggedness and Extended Operation Capability. LCD display is very different from LCD TVs are fan-less closed box units. As a result, it is harder for dust and other contaminants to penetrate the box. So Ruggedness and life of the LCD screen is very important to reduce failures of the LCD displays.
For institutional operations where failure of a screen can create significant inconveniences or loss of business, it does not make any sense to risk the business by using LCD TV. No matter how cheap it costs.
It is also recommended to pay attention to the LCD network capability. Do make sure that the LCD screen features RS-232 and LAN Network Connectivity. The network connectivity will enable remote monitoring of power and other controls can also be done easily. For example, incase there is no signal around, a power save mode can be activated to reduce the brightness of the LCD backlight by activating an energy saving feature made available in the display.
