LONDON — South Korean electronics giant Samsung Electronics Co. Ltd. said it has developed a flexible seven-inch diagonal thin-film transistor LCD on which uses plastic substrate to display 640 by 480 pixel resolution television video pictures.

The plastic substrate that is thinner, lighter and more durable than conventional LCD glass panels, the firm said, and will maintain a constant thickness even when it is bent.

The display is intended for use in notebook computers, cell phones and it could even be included in clothes for wearable advertising panels, Samsung suggests.

Samsung claimed it has overcome several problems with processing to make the plastic substrate practical. Samsung said it has 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.
