Experts talk about buying high-definition TV
Liu Quanen, Senior Engineer, China Electronics Technology Group Third Research Institute
As a flat-panel TV to watch the Olympic high-definition broadcast, it must meet the national high-definition standard, that is, the minimum TV product must reach 720 lines. At present, flat-panel TVs that have reached the high-definition standard on the market have become mainstream, and there are not many models that reach 1080p full-HD resolution, but there are not many TV products that really pass the full-HD standard. Consumers should clearly see the technical parameters of the selected model to ensure that the machine has reached the high-definition standard.
Secondly, the color of watching TV, which includes color saturation, color reproduction and so on. And some specific indicators need to be carefully checked by consumers, such as contrast and brightness. Color and resolution are the main factors for choosing a high-definition LCD TV. At present, there are many manufacturers in the development of the circuit to make some improvements, for example, to improve the refresh rate, anti-tailing and other technologies. Many store staff have exaggerated publicity, hoping that consumers can carefully compare the color of the image before buying, the key is to rely on their own eyes.
Hu Peng, Engineer, China Electronics Standardization Institute
To buy a high-definition LCD TV, the first thing is to look at the resolution. The resolution is the primary technical parameter of the LCD TV. It says how many pixels the full screen has. The same size screen, the higher the resolution, the more pixels, the screen The more delicate the display.
The second is color. At present, the calculation methods of various manufacturers at home and abroad are very different, so the calculated numbers are also very different, so it is necessary to actually choose an electrical store that plays digital streams. Because the digital streams have high resolution and high color numbers, it is convenient. The contrast of color and clarity.
Third, look at the display effect of the motion picture. If you want to watch sports events, the display effect of sports pictures is more important. At present, many manufacturers are doing research and development in this area, mainly to upgrade the ordinary LCD TV screen to 100Hz or 120Hz and so on. For example, Philips' Ritutan core's instantaneous response 100Hz technology.
Fourth, look at the interface. The interface reflects the compatibility of a TV. As a high-definition TV, there must be a digital interface, such as HDMI interface, DVI interface, etc., generally good TV has multiple digital interfaces for use.
Fifth, the backlight. First, the backlight should be designed separately from the LCD screen. The biggest natural enemy of the LCD screen is heat. Many manufacturers combine the backlight and the screen, one reason is to reduce costs, and the other reason is the poor transparency of the LCD screen, supplementary light source, but the catalytic effect of the LCD screen aging, short life.
Sixth, manufacturers will develop some unique functions to attract consumers. For example, left and right time, Ambilight function and so on. This requires consumers to purchase according to their own needs.
