The folks from QuickLogic – specialists in the creation of low-power Customer Specific Standard Products (CSSPs) – have just announced that their RGB-split technology with its unique display signal splitting architecture has been system verified and is ready for adoption into the next generation of foldable tablet computers and smartphones.
A foldable smartphone or tablet offers the advantage of multiple independent displays, separated by a hinge, with which users can simultaneously interact and view. As display content is shared across multiple displays, foldable systems allow a much larger effective display size without the increased physical size inherent in a larger single display system.
This is a feature that is particularly important for the mobile consumer. However, foldable systems present a unique challenge to system designers in that display data must be split across multiple screens, requiring the synchronization of multiple video paths.
Application processors typically used in smartphones and tablets may only have a single display output, or dual outputs that are not synchronized. QuickLogic’s RGB-split technology, implemented as part of a CSSP silicon solution, allows the single incoming display signal from the processor to be split into two, three, or even more displays without the need for expensive custom silicon and processor-intensive software.
“The usability advantages of foldable tablets and smartphones are substantial; however, system design has always been extremely complicated when dealing with splitting and synchronizing display signals,” said Paul Karazuba, senior product marketing manager for QuickLogic. “QuickLogic’s RGB-split technology enables designers to easily adopt the 'foldable' multiple display model into traditional system architectures with a minimum of effort, speeding time to market.”
QuickLogic’s RGB-split technology is available today as part of the ArcticLink II VX2 and VX4 platforms.
