With the continuous improvement of living standards and consumption habits change, people's demand for liquid crystal displays to enhance rational to buy LCD monitor become a more popular topic.

Should pay attention to in the purchase of liquid crystal display elements, including size, color, brightness and contrast ratio, response time, viewing angle, resolution, etc. The size of which is very intuitive, you can choose who to choose according to their needs.

First, the color is a key indicator. For China LCD module monitors, the color is it relative to the cathode-ray display (CRT), a weak indicator. However, color is very important for users, for those graphic designers, gamers, is essential. Therefore, in the purchase of LCD monitors should pay particular attention to its color. Now LG, Philips, Samsung and other brands of LCD monitors in color has a good performance, has made great progress. Such as LG LCD color more than 1670 million.

Buyers can choose according to their needs. If the family does not have to insist on the general application of the highest indicators.

Third, the response time is the liquid crystal by the next turn dark or from dark to clear the time required. Generally speaking, the shorter the response time, response faster, the better. According to the human eye's response time, response time of 50 milliseconds or so, it will not appear more serious motion picture hysteresis. The current standard LCD 50 ms response time around the majority, but there are a few models can reach the whole 30 milliseconds.

Fourth, Philips, LG and other traditional brand of professional TFT module monitor viewing angle reached 140 degrees to 160 degrees. If a person uses 120-degree viewing angle is sufficient.

Fifth, all the display resolution is an important technical indicators to buy one. The higher the resolution, the better show. LCD has a resolution different from the CRT monitor, because it generally could not be adjusted, and regulations set by the manufacturer, only operates at a nominal resolution mode, the LCD display in order to achieve the best results. In general a resolution of 1024 × 768 LCD display enough to support most of the current general purpose users.
