LED CCFL a few thin backlight menacing without a place to live in

Loading LED backlight notebook computer panel is in the rapid growth of the market. DisplaySearch LED backlight panel of the latest quarterly shipment and forecast report pointed out that the permeability of LED backlight in the notebook computer panel is expanded by 36% in the first quarter of 2009 to 81.5% in the first quarter of 2010, the end of this year is expected to forecast the penetration rate will reach 97.7%; in other words, the traditional CCFL (cold cathode fluorescent lamp) backlight will close completely out of the state in the Notebook PC market.

DisplaySearch said that at present in the LED backlight notebook computer panel part has two structures: a thin wedge (SlimType) and (Wedgetype); the difference is mainly in the light guide plate (LightGuidePlate) technology and the backlight board structure. Thin (SlimType) LED backlight panel can be reduced to 3.0mm-3.6mm and the thickness of the wedge (Wedgetype) Notebook LED backlight panel thickness is 5.2mm-5.8mm. and thin (SlimType) quality and technology level of the LED backlight requirements are relatively high, and the need to use thin materials and components such as LED, a light guide plate and so on.

The thin LED backlight panel supply due to yield problems of the light guide plate has been unable to successfully grow, "DisplaySearchNotebook and panel analyst AnitaHuang said," and compared to the thin LED backlight LED backlight wedge there are at least $5 premium, and equipped with thin LED backlight panel for Notebook generation plants in assembly the process often encountered many challenges of the panel structure is too fragile. "

Although there are problems of cost and assembly yield, equipped with thin LED backlight panel will continue rapid growth; the main reason is because the Notebook brand will be more and more thin appearance design as an important factor of product differentiation and market in the Notebook market. At the same time, the yield of LED thin light guide plate is rapidly improved, and the thin LED backlight panel production scale has been expanding and the expected cost and the price gap between the thin LED backlight with wedge LED backlight will be gradually reduced.

An analyst at DisplaySearchPC HidetoshiHimuro, said: "another advantage of thin LED backlight panel is connected between the terminal plate and the backlight panel is relatively short, relatively simple structure, so in the design of anti electromagnetic interference prevention safety is relatively simple. At the same time, thin LED backlight panel and panel design can also be NotebookPC design engineers can have more space to design the network antenna module and the associated connection line. "
