Samsung claims 'slimmest' mobile LCD screen

Samsung's 0.82mm-thick LCD panel

Samsung Electronics Co. Ltd announced it has developed the thinnest reported LCD panel. At 0.82mm, the company said this LCD panel is no thicker than a credit card, and is 0.07mm thinner than the panel previously reported to be the world's slimmest. The company also announced the development of a new mobile technology called "i-Lens," which it said is 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.

To achieve the slimmer package 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 new i-Lens technology, on the other hand, promises a thinner, highly integrated LCD module that protects the mobile phone's main display better than previous designs, making it more resistant to damage from shock and vibration. In deploying this technology, manufacturers can trim 1.4mm to 2.4mm from the thickness of a mobile phone.

Today, a typical mobile phone screen leaves a 2mm to 3mm space above the panel before attaching a reinforced plastic sheet to protect the LCD module. With the i-Lens process, a shock-resistant protective sheet is fastened directly to the LCD module, eliminating the space between it and the panel surface. The thickness of the LCD module is thereby reduced to 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 pixels) resolution, 300nit brightness and a 500:1 contrast ratio. Mass production is scheduled Q2 2007.
