Since 2008 , LED backlights have gradually entered industrialization and their market share has been expanding. From the beginning to the application of notebook computers , to the present application for display, LCD TV , LED backlight products continue to emerge , the market share continues to increase. In the small and medium size field, LED backlights have taken a big advantage. In 2009 , the LED backlight market share in the NB market has exceeded 50% , and it is expected to grow to over 80% in 2010 .
In the large-size field, LCD TV applications are represented, although leading TV brands such as Samsung, Philips, Sharp, Sony, Toshiba, Vizio and LG have announced that they will increase the use of LED backlight LCD TVs in the second half of this year, but 09 The annual market penetration rate is only about 3% , but with the vigorous promotion of the main manufacturers, it is expected to grow to 10% by 2010 .
From the perspective of the country or region where the backlight module manufacturer originates, Taiwan and South Korean companies account for 40% to 45% of global shipments. The global backlight module manufacturers mainly include Taiwan’s Chi Mei, AUO, Zhongqiang Optoelectronics, and Rui. Instruments, Keqiao , Taesan , Heesung in Korea, and Sharp, Stanley, etc. in Japan. In China, there are also emerged as backlighting and backlight companies represented by BOE and Hisense.
  According to GLII survey data, the application of LED backlights in small and medium-sized panels has almost completely replaced traditional cold cathode lamps, and the shipment of LED backlight modules in large-size panels will reach 180 million in 2012 .
In 2009 , the demand for LCD panel backlights became the main growth driver of the LED market. From the notebook computer display panel, LEDs were used as backlights, and LCD TV panels began to adopt LED backlights. The demand for LEDs rose sharply and the market began to heat up. Especially in large-size TV backlights, in 2009 , whether it is Samsung, LG , Ruixuan, Sharp, Panasonic and other international manufacturers, or domestic domestic manufacturers such as Hisense, TCL, Skyworth, Tongfang, etc., have launched various sizes. The LED- backlit TV enhances the proportion of LED- backlit models. According to experts' prediction, the use of large-size TV backlights brought by Samsung as a pioneer has only zero penetration at the beginning of the year. In 2009 , the penetration rate was less than 4% . It is estimated to reach 10% next year and 40% in 2012 . . Since last year, the global panel factory has been actively deploying LED backlights, which has created certain pressure on independent LED factories. Although there has not been a major erosion of LED packaging factory orders, if the price of the products is disrupted by low-priced products, the domestic packaging plants may be more or more Less will form a certain pressure.
At present, Ruiyi, Tongbao, Zhongqiang and Chimei of Taiwan are the main suppliers of LED LCD backlight modules. Although Skyworth, Hisense and Konka have established their own LED backlight module bases in China, their upstream LED packages also need to rely on five major LED chip factories in Japan and other countries.
