The output value of light-emitting diode (LED) backlight sources will shrink slightly in 2013. In 2013, the LED backlight market continued to expand, but under the oversupply of the LED market, the unit price of LEDs plummeted, resulting in a slight reduction in the overall output value of global LED backlights this year.
Guo Ziling, a researcher in the Energy Saving Technology Research Department of the Industrial Economics and Trends Research Center (IEK) of the Industrial Technology Research Institute, said that smartphones and TVs were still the main engine for the growth of LED backlights in 2013. Among them, LED backlights for large and medium-sized displays have occupied the world The proportion of LED backlight shipments exceeds 50%, which becomes the key to the overall output value of the LED backlight market.
Guo Ziling further pointed out that despite the strong growth in demand for LED backlights for large and medium-sized displays in 2013, taking the 7020 package type LEDs for edge-lit LED backlights for TVs as an example, the price in 2012 exceeded US $ 0.2; the price in 2013 has been Reducing to 0.18 ~ 0.2 US dollars, based on this estimate, the global output value of large and medium-sized display backlights in 2013 will decline.
However, it is worth mentioning that since the shipment of large-size TVs larger than 50 inches will increase significantly this year, it is expected to fill the vacancy in the output value of LED unit prices, which led to a slight decline in the global LED backlight output value in 2013.
It is understood that in view of the current mainstream 42-inch low-cost direct-lit LED backlight, the number of LEDs used is about forty to forty-eight, accounting for 51% of the total cost of the LED backlight source material list (BOM), about 12-14 USD; There are about 72 edge-lit LED backlights, accounting for about US $ 23-26 of the LED backlight BOM cost. As for the edge-lit LED backlight for 55-inch large-size TVs, the number of LEDs used is more than one hundred and sixty, accounting for 27 to 30% of the LED backlight BOM cost, about 110 to 115 dollars, which shows that the 55-inch large The contribution of the size TV to the output value of the LED backlight.
The IEK of the Industrial Research Institute estimates that the output value of LED backlights for large and medium-sized displays will climb to US $ 3.01 billion in 2013, which is only a slight decrease from the US $ 3.05 billion in 2012. TVs have accounted for more than 10% of the market for LED backlights for large and medium-sized displays, and maintain a double-digit growth rate each year, which will become a major driving force for the growth of LED backlights for large and medium-sized displays.
At the same time, according to the statistics of market research agency Strategies Unlimited, the total revenue of the LED component market in 2012 reached 13.7 billion U.S. dollars, of which lighting applications were 3.11 billion U.S. dollars, accounting for 23%, and slightly exceeded 3 billion in TV and display backlights. 60 million US dollars, becoming the largest application market for LED components. Coupled with the LED development-related plans released by mainland China a year ago, the overall prospects for the entire LED light source market are very promising, and as for who is the "first brother" among them, the problem is not very big.
