Cheap Monitors: types, characteristics, operation

Today, they are divided into two types: liquid-crystal (LCD in common), OLED displays, and "plasma".

Types of inexpensive monitors

liquid crystal

Liquid crystal made of substance (cyanophenyl) situated in the liquid state. At the same time it has properties similar to crystalline solids. Let's just say, it's fluid, which has optical anisotropy.

The LCD display consists of small cells, called pixels. They required us to build an image.

OLED

Consider how the OLED type. Abbreviation OLED (Organic Light-Emitting Diode) is translated as organic svetoemissionny diode. OLED working principle is the ability of some organic polymers emit light when an electric current to them. This process is called luminescence.

"Plasma"

Next view - "plasma". It is very inconvenient to use. "Plasma" Sizes start at 30 inches, which is not convenient until you use them, and for the price it is not profitable. More "plasma" less bright, so they view the image in bright sunlight will not work.

It is worth noting that the "plasma" is the only, but the bright plus. This contrast. According to this indicator, some plasma screens are superior to liquid crystal twice. The higher the contrast, the sharper the image.

At the positive side "plasma" ends thus advantageous embodiment there is only liquid crystal displays.

Features inexpensive monitors

Brightness and Contrast

If you have on the table is only one screen, then consider two options: brightness and contrast. Brightness should not be less than 250 cd / sq. meter.

It is important to know that these two characteristics are independent of each other. If you have good brightness, but weak contrast ratio, the picture will not suit you. Most manufacturers often incorrectly indicate a dynamic contrast ratio. It is necessary to take this into account.

If you have a brightness of 250 cd / m². meter, the contrast ratio should be between 900 to 1000 to 1. If the figure is smaller, the picture will be a little "zamylenny", if more, the dark parts of the image will be merged with each other.

These characteristics can not be adjusted. So you need to choose the appropriate parameters at once. For example, if a monitor for gaming, the figures are as follows: Brightness 375 cd / m². meter 1000: 1.

matrix screen

If two screens - are important they die, because we look at them from different angles. The easiest and cheapest option - a TFT-TN matrix, then there is a simple office monitor. But its biggest drawback is that you can look at it at right angles.

When viewed from above, the picture seems brighter, if below, then - a dark, well, if you look at it from the sides, it is possible simply do not see any image. Their main advantage - it is a price they are cheap.

Better option to add money and buy a monitor with TFT-TN Led matrix. It is characterized by LED, so it can be viewed from different angles. They are lighter and thinner, though more expensive, it turns profitable.

The next version (more superior) - is IPS (Lifelike Color Expression) matrix such stands on the "top" devices and flagship smartphones.

Its main feature is that it is possible to look at a zero angle, the image will stay bright and crisp.

Consider another type of matrices - VA. It is similar to the parameters between IPS and VA and IPS notice someone who is professionally engaged in graphics and color correction. But the output device graphics c VA matrix are cheaper.

Exploitation

After buying a new monitor set correctly.

• Near the windows should not be, because the light passing through them, leaving patches of light that strains the eyes. It is better to put it in the center of the desktop as another location will cause pain in the neck and back.
• He must stand at arms length from your eyes so that your eyes just above the middle of the screen.
• If it is regulated by the slope, make sure that the bottom of the screen is slightly ahead. This will allow better perceive the image.
• Do not overdo with brightness adjustment, excessive levels of straining your eyes. As a precaution - do not sit for 3-7 hours at the screen, it adversely affects the vision.

Often free from dust and dirt, make sure that it does not remain on the tiny droplets of fluid. These measures will allow you to fully enjoy the high-quality image.

malfunctions

Highlighting disappears after some time of operation, after switching on or immediately after turning. The reasons may be as follows:

• Power Supply;
• inverter;
• backlight.

Such defects are associated with, or guarantee breakage, or failure of parts. You must contact the service center.
