says 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, 640×480 (VGA-standard) flexible display uses a transparent plastic substrate that is said to be thinner, lighter and more durable than the conventional LCD glass panels used today. Moreover, the full-colour 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, allowing much greater freedom in commercial designs requiring flexible full-colour, high-resolution display components.
The seven-inch flexible TFT-LCD is optimised for mobility applications, including cell phones and notebook computers. System designers and OEMs also may apply the advanced Samsung display technology to new applications, such as wearable electronic display designs.
The new display is double the size of Samsung’s five-inch flexible LCD display prototype announced in January 2005.
With this advancement, Samsung says it has overcome 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.
