I. Brand
International famous brand is excellent quality, but the price is not cheap. Domestic brands of plasma screen are not their own production, quality is not easy to control, but the price is cheap. Although it is divided into domestic brands and foreign brands, but now the origin of foreign brands are in China, so the difference in this respect is not very big, the price gap between domestic brands and foreign brands is also narrowing.
Two, the size of the TV
As usual, we rely on the size of the room and watching distance to determine the size of the purchase of flat screen TV, it is really mainly to choose the size of the viewing distance, but in order to make home deployment voucher coordination, room size can be used as an alternative parameter to determine the purchase size. The recommended reference is: the linear distance within three meters, the size of the room is 20 square meters, choose 25-29 inches; The linear distance of about three meters, the size of the room is 20 ~ 30 square meters, choose 29-34 inches; Four meters in a straight line distance, the size of the room in 30 ~ 40 square meters, choose 35-43 inches; Four meters above the linear distance, the room size of more than 50 square meters, choose more than 43 inches of LCD TV.
Third, the problem of bad spots and bright spots
The simplest way to check whether the LCD TV has bright spots is to let the screen all black, about 30 centimeters away from the LCD TV screen, to see if there are bright spots in the black. Then make the screen all white, see if there are any broken spots. Then change the color to red, green, blue to check the integrity of the color dots, at about 2.5 meters to see if the brightness of the picture is even, these checks should make the whole screen is a solid color.
Four, response time
The response time is also important, as it determines whether blur and drag will occur when displaying high-speed motion images, and the prevailing 8 milliseconds response time is adequate for use. Generally speaking, the faster the reflection time, the LCD TV will be less drag, residual image signs. It’s a good idea to see how real action plays out before you buy.
Five, hard screen is as good as soft screen
“Soft, hard” alone can not be very accurate to distinguish the interests of the LCD panel. The so-called hard screen light transmission performance and soft screen in quality is not significantly different, hard screen external precious film will not cause poor light transmission, film and screen bonding process requirements are also quite good. Without the soft screen with precious outer film, as long as consumers pay attention to the use of gravity impact or with sharp objects, as usual is not easy to scratch. Therefore, the choice of liquid crystal can not be solely based on the soft and hard screen selection, so should certificate brand and quality to hold the selection.
Vi. After Sale
After-sales service is also the main factor to consider, generally speaking, the domestic famous brand service points more, more convenient maintenance.
