Samsung Electronics rolls out LCD panel

Samsung Electronics announced that it has developed a
transmissive thin-film transistor, liquid crystal display (TFT LCD), 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, allowing much
greater freedom in commercial designs requiring flexible full-color,
high-resolution display components. The seven-inch flexible TFT-LCD is optimized
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 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.
