Loading LED backlights is growing rapidly in the notebook panel market. DisplaySearch's latest quarterly LED backlight panel shipment and forecast report pointed out that the penetration of LED backlights in notebook panels has expanded from 36% in the first quarter of 2009 to 81.5% in the first quarter of 2010, and is expected to be expected by the end of this year. The penetration rate will be as high as 97.7%; in other words, the traditional CCFL (Cold Cathode Fluorescent Lamp) backlight will be in a state of complete exit in the Notebook PC market.

DisplaySearch said that there are currently two types of LED backlights in notebook panels: SlimType and Wedgetype; the difference is mainly in the LightGuidePlate technology and backlight structure. SlimType LED backlights reduce panel thickness to 3.0mm-3.6mm and Wedgetype LED backlights have a Notebook panel thickness of 5.2mm-5.8mm. In addition, the quality and process level of SlimType LED backlights The requirements are relatively high, and thinner materials and components such as LED strips, light guides, and the like are required.

"The supply of thin LED backlights has not been able to grow smoothly due to the yield of light guides," said AnitaHuang, a Display Analystbook and panel analyst. "And thin LED backlights have a premium of at least $5 compared to wedge-shaped LED backlights. In addition, for the notebook OEM, the panel with the thin LED backlight often encounters many panel structures that are too fragile.

Despite the cost and assembly yield, panels with thin LED backlights will continue to grow rapidly; the main reason is that more and more Notebook brands have listed thin designs as a product and market differentiation in the Notebook market. Important factor. At the same time, the yield of thin LED light guides is rapidly improving, and the economic scale of thin LED backlights is expanding. It is expected that the cost and price gap between thin LED backlights and wedge LED backlights will gradually shrink.

DisplaySearchPC analyst HidetoshiHimuro said: "Another advantage of the thin LED backlight panel is that the connection between the backlight panel and the panel is shorter and the structure is simpler, so it is easier to prevent electromagnetic interference. The thin design of the thin LED backlight panel and the panel can also allow NotebookPC design engineers to have more space to design the network antenna module and related connection lines."
