Thin LED backlight replacement CCFL will be just around the corner

Loading LED backlight notebook computer panel is in the rapid growth of the market. The latest DisplaySearch LED backlight panel in quarterly shipment and forecast report pointed out that at the end of the year to predict permeability LED backlight in the notebook computer panel will be as high as 97.7%; in other words, the traditional CCFL (cold cathode fluorescent lamp backlight) will be close to completely withdraw from the state in the NotebookPC 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.

"Thin LED backlight supply due to yield problems of the light guide plate has been unable to successfully grow," DisplaySearchNotebook and panel analyst AnitaHuang said, "compared to the thin LED backlight LED backlight wedge there are at least $5 premium, plus the type LED backlight board equipped with thin panel for Notebook generation plant in the assembly process often encounter many challenges to 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.

DisplaySearchPC analyst at 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, you can design the network antenna module and the associated connection line. "

The advantages of thin LED backlight board has obviously, believe that in the near future, loading the LED backlight panel led the notebook computer market will bring the audience to point the day and await for it, thus more perfect visual enjoyment.
