Samsung Develops World's Slimmest Mobile LCD Screen

Samsung announced today that it has developed the thinnest reported LCD panel. Measuring no thicker than a credit card at 0.82 mm, the new LCD is 0.07 mm thinner than the panel previously reported to be the world's slimmest.
To achieve the slimmer size, Samsung's Mobile Display Team redesigned the light guide plate subassembly and the glass substrate, which accounted for most of the LCD module's thickness.
The company also announced that it has developed a new mobile technology, which it is calling, "i-Lens", for integrating the entire panel assembly, including a protective layer, into a single, thinner module that is more shock-resistant and easier to read than conventional panels.
Further contributing to the trend toward slimmer phones with its new i-Lens technology, the integrated LCD module protects the mobile phone's main display better than previous designs, making it more resistant to damage from shock and vibration. In deploying Samsung's i-Lens technology, manufacturers can trim 1.4 to 2.4 mm from the thickness of a mobile phone.
Today, a typical mobile phone screen leaves a 2 to 3 mm space above the panel before attaching a reinforced plastic sheet to protect the LCD module. In Samsung's new i-Lens process, a shock-resistant protective sheet is fastened directly to the LCD module, thereby eliminating the space between it and the panel surface. With i-Lens, the thickness of the LCD module is reduced to a mere 0.82mm, while resolving the sunlight reflection problem inherent in the use of reinforced plastic. As a result, the panel is much easier to view outdoors.
The new LCD screen is available in 2.1 inch-diagonal and 2.2-inch-diagonal screen sizes. It features qVGA (240 x 320 px) resolution, 300 nit brightness and a 500:1 contrast ratio. Mass production is scheduled to begin in the second half of 2007.
