Ultra thin design is the cause - edge emitting LED backlight with the increasing number of LCD TV

In 2009, South Korea's Samsung Electronics edge light-emitting LED backlight LCD TV as an opportunity to come out of the reasons for the use of LED from the original emphasis on high quality turned to the use of ultra-thin advantage of the importance of design". In view of this, we are scheduled to be held in May 11th, "Display Search LED integrated Forum 2010", was scheduled to attend the forum analyst LED latest trends commentary series of second articles.

2010 edge light LED backlight will become the mainstream

Although equipped with LED backlight can support environmental protection (low power consumption, and improve the quality of the mercury free) (by reducing the black level to improve contrast), but 2010 will pay more attention to the design of ultra-thin edge light type LED backlight the growing popularity of the year. In the future to promote the popularity of LED backlight is the biggest issue to reduce costs. How to reduce the number of LED is the most important point to achieve the cost reduction, which further promote the popularity of edge emitting LED backlight.

In January 2010 the "CES" (American appliance exhibition), a large number of LED backlight LCD TV new models released, but some models of SONY, South Korea's LG electronics and Vizio in the United States, has become the mainstream of edge light type (Figure 1).

Of course, the major companies are emphasizing the design of their products, environmental protection and high quality. However, the focus is different. It can be said that the European Holland Royal PHILPS Electronics (Royal Philips ELectronics) is the focus in the field of environmental protection, the Japanese manufacturer SHARP will focus on high quality, while South Korean manufacturers will focus on the use of the advantages of the ultra-thin design. Recently, SONY and Toshiba have both announced that it will put more emphasis on the design of the market for new models.

LCD TV prices continued to decline, the gradual commercialization of severe market environment, equipped with LED backlight is designed to maximize the premium. Recently in China, local brands have also been equipped with LED backlight. The reason is that by equipped with LED backlight, can give consumers the impression of high quality (Premium Image), can sell a slightly higher price.

2013 LED backlight equipped with a rate of more than 60%, straight down will gradually increase

We have published a "survey of global TV supply quarterly Expanded Edition (TV data & IC LED equipped with speed drive equipped with backlight LCD TV Data Collection Edition)". The report is expected in 2013 LED backlight LCD TV demand (number) is about 140 million units, LCD TV LED backlight equipped with a rate of more than 60%.

The report holds the results of each of the two types of edge emitting light and straight down LED backlight, and forecasts. Although the 2010 edge glow LED backlight is the mainstream, but is expected in 2013 straight down LED backlight market share will gradually increase to 17% (Figure 2). First of all, due to the use of edge light type, the number of LED reduction and efficiency will be gradually improved. After that, through the full local brightness control (Local Dimming) to reduce the power consumption of the straight down will gradually increase.

In the May 11th Display Search LED Forum 2010, professional analysts will be based on the latest survey data related to the LED plus introduction.
