Buy flat-panel TVs don't fall into the trap of low technical standards can not be ignored

Flat giants Xoceco to remind consumers: buy flat-panel TV price is a big misunderstanding, technology is the key to the standard

Recently, the reporter visited the United States, Suning, Yongle and other large home appliance stores was informed that 51 consumer golden week, the most popular flat-panel TV sales.

Xoceco Guangdong Branch General Manager Zhang Shi Ming told reporters that the flat-panel TV in 51 sales, mainly due to the flat-panel TVs are thin, high resolution and is favored by many consumers, but there are still many consumers do not know the choice of LCD TV, plasma TV is good?

Ishi Akim pointed out, will inform consumers Xoceco some main technical indicators to compare, so that consumers do not easily fall into the trap of low prices.

LCD and more young consumer groups

Ishi Akim said, LCD TV consumer groups are mostly young fashion.

First, the first step to see the brightness and contrast. High brightness, white will appear bright white, not gray. High contrast, the dynamic range of white and black, the greater the bright light up, black can go down, the image texture, not too dull.

The LCD screen latest generation, the brightness can reach 550-600 Bennett, contrast can reach 800:1, or even 1000:1, the black and white image texture can be compared with CRT tv. A year ago, LCD screen brightness is only 450 nits, the contrast is only 550:1, then the black hair looks black, dark background is also slightly shiny, compared with CRT TV, a little white image. At present, different manufacturers with different production processes of the screen, some contrast only reached 600:1, and some can reach 1000:1, and many manufacturers to use some inventory low brightness screen production of LCD TV sales, consumers should pay attention to when choosing the screening index.

Experts pointed out that the influence of a LCD TV viewing more key indicators is the response time gray scale transform. Early LCD TV is 25 milliseconds, for fast moving objects, such as the injection of football, there will be a string of trailing shadows, resulting in blurred motion image.

Later improved, reaching 16 milliseconds, the response time of a new generation of LCD screen has achieved 8 milliseconds. Under normal circumstances, the human eye has not been aware of the phenomenon of moving objects.

A LCD screen obvious advantage is high resolution LCD screen, most is 16:9 wide, 1366x768 resolution, a 1280x768 or 1280x720, almost only 20 inch 4:3 screen is 640x480 or 800x600. but there are some manufacturers launched 37/42/47 Full HD screen resolution reached 1920x1080p. the full HD screen and the brightness of 600 nits, in contrast to 1000:1, the response time is 8 milliseconds, become the upcoming launch of the best viewing high-definition television screen, the future development of 1080p at the same time, display the trend of the industry.

Beware of get out of plasma

It is reported that, plasma TV screen sub has experienced roughly four stages of development in recent years. The first generation of screen brightness is lower than 550 nits, in contrast to 500:1, the second generation of screen brightness of 700 nits, contrast 1000:1, the third generation of screen brightness reached 1000-1200 Bennett, contrast 3000:1 to 5000:1, the fourth generation of screen brightness contrast 10000:1. 1300-1500 Bennett, currently on the market there have been some million of the plasma, low price, let many consumers tempted, but according to the experts pointed out that, due to upstream display manufacturers inventory, some manufacturers to buy a large number of first and second generation of low brightness, low contrast plasma screen is used to digest inventory, usually the plasma screen dark and viewing effect is poor, consumers in the purchase must pay attention to the investigation of these plasma brightness and in contrast, so as not to get out of the market products.

At present, the domestic flat-panel TV pioneer, Xiamen Overseas Chinese electronics has taken the lead in the domestic use of the brightness of 600 nits, in contrast to 1000:1, the response time of 8 milliseconds, 1920X1980P Full HD screen, launched a series of 37, 42 and 47 large screen LCD TV on the eve of may. At the same time push listing and screen brightness of 1500 nits, 42 inch plasma TV contrast of 10000:1, at the same time these new flat-panel TVs with a high level of "God microcrystal painting" image processing technology.
