FAQs (Frequently Asked Questions)

scanning lines at the same time, thus distorting the picture.

Q: What does the Refresh Rate mean for LCD?

A: Unlike CRT display technology, in which the speed of the electron beam is swept

from the top to the bottom of the screen determines flicker, an active matrix display

uses an active element (TFT) to control each individual pixel and the refresh rate is

therefore not really applicable to LCD technology.

Q: Will the LCD screen be resistant to scratches?

A: A protective coating is applied to the surface of the LCD, which is durable to a

certain extent (approximately up to the hardness of a 2H pencil). In general, it is

recommended that the panel surface is not subject to any excessive shocks or

scratches.

Q: How should I clean the LCD surface?

A: For normal cleaning, use a clean, soft cloth. For extensive cleaning, please use

isopropyl alcohol. Do not use other solvents such as ethyl alcohol, ethanol, acetone,

hexane, etc.

Q:Can I change the color setting of my monitor?

A:Yes, you can change your color setting through OSD control as the following

procedures,

1. Press "MENU" to show the OSD (On Screen Display) menu

2. Press "Arrow" to select the option "color" then press "MENU" to enter color setting,

there are five settings as below.

LCD Panel Technology

Q: What is a Liquid Crystal Display?

A: A Liquid Crystal Display (LCD) is an optical device that is commonly used to

display ASCII characters and images on digital items such as watches, calculators,

portable game consoles, etc. LCD is the technology used for displays in notebooks

and other small computers. Like light-emitting diode and gas-plasma technologies,

LCD allows displays to be much thinner than cathode ray tube (CRT) technology.

LCD consumes much less power than LED and gas-displays because it works on the

principle of blocking light rather than emitting it.

Q: What differentiates passive matrix LCDs from active matrix LCDs?

A: An LCD is made with either a passive matrix or an active matrix display grid. An

active matrix has a transistor located at each pixel intersection, requiring less current

to control the luminance of a pixel. For this reason, the current in an active matrix

display can be switched on and off more frequently, improving the screen refresh time

(your mouse pointer will appear to move more smoothly across the screen, for

example). The passive matrix LCD has a grid of conductors with pixels located at

each intersection in the grid.

Q: What are the advantages of TFT LCD compared with CRT?

A: In a CRT monitor, a gun shoots electrons and general light by colliding polarized

electrons on fluorescent glass. Therefore, CRT monitors basically operate with an

analog RGB signal. A TFT LCD monitor is a device that displays an input image by

operating a liquid crystal panel. The TFT has a fundamentally different structure than

a CRT: Each cell has an active matrix structure and independent active elements. A

TFT LCD has two glass panels and the space between them is filled with liquid

crystal. When each cell is connected with electrodes and impressed with voltage, the

molecular structure of the liquid crystal is altered and controls the amount of inlet

FAQs (Frequently Asked Questions)

lighting to display images. A TFT LCD has several advantages over a CRT, since it

can be very thin and no flickering occurs because it does not use the scanning

method.

Q: What kind of wide-angle technology is available? How does it work?

A: The TFT LCD panel is an element that controls/displays the inlet of a backlight

using the dual-refraction of a liquid crystal. Using the property that the projection of

inlet light refracts toward the major axis of the liquid element, it controls the direction

of inlet light and displays it. Since the refraction ratio of inlet light on liquid crystal

varies with the inlet angle of the light, the viewing angle of a TFT is much narrower

than that of a CRT. Usually, the viewing angle refers to the point where the contrast

ration is 10. Many ways to widen the viewing angle are currently being developed and

the most common approach is to use a wide viewing angle film, which widens the

viewing angle by varying the refraction ratio. IPS (In Plane Switching) or MVA (Multi

Vertical Aligned) is also used to give a wider viewing angle.

Q: Why is there no flicker on an LCD Monitor?

A: Technically speaking, LCDs do flicker, but the cause of the phenomenon is

different from that of a CRT monitor -- and it has no impact of the ease of viewing.

Flickering in an LCD monitor relates to usually undetectable luminance caused by the

difference between positive and negative voltage. On the other hand, CRT flickering

that can irritate the human eye occurs when the on/off action of the fluorescent object

becomes visible. Since the reaction speed of liquid crystal in an LCD panel is much

slower, this troublesome form of flickering is not present in an LCD display.

Q: Why is an LCD monitor virtually low of Electro Magnetic Interference?

A: Unlike a CRT, an LCD monitor does not have key parts that generate Electro

Magnetic Interference, especially magnetic fields. Also, since an LCD display utilizes

relatively low power, its power supply is extremely quiet.

FAQs (Frequently Asked Questions)

Ergonomics, Ecology and Safety Standards

Q: What is the CE mark?

A: The CE (Conformité Européenne) mark is required to be displayed on all regulated

products offered for sale on the European market. This 'CE' mark means that a

product complies with the relevant European Directive. A European Directive is a

European 'Law' that relates to health, safety, environment and consumer protection,

much the same as the U.S. National Electrical Code and UL Standards.

Q: Does the LCD monitor conform to general safety standards?

A: Yes. The specification page provides detailed data on safety standards.

More information is provided in the Regulatory Information section.
