Laptops grow fast with thin LED Backlight

On June 9, 2010, thin LED backlights with thin light guides are growing rapidly in the notebook panel market. According to DisplaySearch's latest "Quarterly LED Backlight Panel Shipment & Forecast Report", the proportion of thin LED Backlight in notebook panels will be 16% in the fourth quarter of 2010. Growing to 31% in 2010. The report pointed out that the penetration of LED backlight in the notebook panel has expanded from 36% in Q1'09 to 81.5% in Q1'10. It is expected that the penetration rate will reach 97.7% by the end of this year; in other words, the traditional CCFL backlight in the Notebook PC market. Will be near the state of complete exit.

DisplaySearch said that there are currently two types of LED Backlight in the notebook panel: Slim Type and Wedge type; the difference is mainly in the Light Guide Plate technology and backlight structure. The Slim Type LED backlight reduces the panel thickness to 3.0-3.6mm and the Wedge type LED Backlight has a Notebook panel thickness of 5.2-5.8mm. In addition, the quality and process level requirements of Slim Type LED backlights are relatively high, and thinner materials and components such as LED strips, light guides, and the like are required.

According to DisplaySearch, the supply of thin LED backlights has not been able to grow smoothly due to the yield of light guides, and the thin LED backlights have a premium of at least $5 compared to wedge-shaped LED backlights, plus a thin LED backlight. Panels often encounter the challenge of many panel structures being too fragile during the assembly process for Notebook foundries. However, despite the cost and assembly yield issues, panels with thin LED backlights will continue to grow rapidly; the main reason is that more and more Notebook brands have classified thin designs as product and market differentiation in the Notebook market. An important factor. At the same time, we have observed that the yield of thin LED light guides is improving rapidly, and the economic scale of thin LED backlights is expanding. We expect the cost and price gap between thin LED backlights and wedge LED backlights to gradually shrink. .

Fiber Optic Splice Closure is a fiber management products typically used with outdoor fiber optical cables.XRX can supply two styles Fiber Optic Splice Closures: horizontal (inline) and vertical (dome). These two kinds of fiber optic splice closures are made of excellent engineering plastics. And with various ports types, fittings different fiber optic core numbers.
