(09 Jun 2005) Yet as flexible displays inch towards the market, their initial uses are likely to be more prosaic: on shelf-edges and signs in shops, says Kimberley Allen of iSuppli, a market-research firm. “What you want in a flexible display is something that can go on a shelf-edge display or be wrapped around a post, is light and looks cool,” she says. One idea is to update labels on shelf-edges over wireless links. This would let shops update their prices more quickly and cheaply than is currently possible. They could then try out new price regimes in individual locations, or quickly re-price goods to clear them at the end of the day. There would be similar advantages for large signs, which could be quickly updated to reflect changing circumstances or to promote special offers.
