The best selling Samsung LED TV, the average monthly sales in Chengdu but also about 60 units. The store believes that led to LED praised the two reasons: one is the stage of the LED LCD market development is faced with the problem of a small number of products, a single product size, consumers can choose a narrow range, whether foreign or domestic funded enterprises, currently available LED new and more concentrated in the big screen consumer groups, is also more concentrated in commercial customers; second, LED TV price is high, the average consumer is not easy to accept. For example, a SONY 55 inch Full HD LCD is priced at 15000 yuan, while a 55 inch LED TV price is as high as 42900 yuan, in the flat-panel TV has not completely universal stage, consumers pay more attention to the price and brand.
