Thin LED backlight gives CCFL a few footholds
At present, there are two structures in the LED backlight of the notebook panel: SlimType and Wedgetype; the difference is mainly in the technology and backlight structure of the LightGuidePlate. 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.
Another advantage of the thin LED backlight panel is that the connection terminal between the backlight panel and the panel is short and the structure is relatively simple, so the prevention design against electromagnetic interference is relatively simple. At the same time, 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. â€
