Samsung ci annuncia oggi di aver sviluppato il più grande monitor LCD flessibile del mondo. Sono stati raggiunti infatti ben 7" pollici come viene specificato in dettaglio in questa press release:

Seoul, Korea – November 28th, 2005 - Samsung Electronics Co., Ltd., announced today that it has developed the world’s largest transmissive TFT LCD (thin-film transistor, liquid crystal display), with sufficiently high resolution to display digital television content.

The seven-inch, 640x480 (VGA-standard) flexible display uses a transparent plastic substrate that is thinner, lighter and more durable than the conventional LCD glass panels used today. Moreover, the full-color transmissive LCD panel maintains a constant thickness even when it is bent.

Considered the next-generation in flat panel displays, this technology involves the use of pliable plastic instead of rigid glass substrates in TFT-LCD production. The plastic will not break when flexed, llowing much greater freedom in commercial designs requiring flexible full-color, high-resolution display components.

The seven-inch flexible TFT-LCD is optimized for mobility pplications, including cell phones and notebook computers.
System designers and OEMs also may apply the advanced Samsung display technology to new applications, such as fashion-enhancing or wearable electronic display designs, thanks to its differentiated flexible format.

The new display is double the size of Samsung’s five-inch flexible LCD display prototype announced in January 2005.

With this advancement, Samsung has overcome daunting problems involving the plastic substrate’s heat sensitivity including a previous challenge to maintain the display’s substrate thickness when subjected to typical commercial thermal conditions. Samsung developed an low-temperature processing technique that can be used to manufacture the display’s amorphous thin-film transistors, color filters and liquid crystals at process temperatures much lower than standard glass-based, amorphous silicon (a-Si )technology.

Drawing on technology adopted for the production of low-temperature (less than 130 degrees Celsius) a-Si TFT LCD and color filter, Samsung’s proprietary LCD technology minimizes substrate deformation by preventing not only changes in thickness but also distortion of images by binding two extremely-thin panels together through a new proprietary system design.

The latest flexible LCD panel was developed under a three-year program funded by Samsung Electronics’ next-generation display development group under the auspices of the Korean Ministry of Commerce, Industry and Energy, supported by Samsung’s Corporate Research Fund.
