Abstract The application of TFT displays for handset applications requires new display system architectures in order to achieve desired power targets and to enable handset features such as integrated cameras. There are significant benefits to embedding a framestore into the source driver chip of a handset display system. This paper explores these benefits with respect to typical handset usage models, power consumption, memory architecture, camera/video functions, and other advanced techniques for display power optimization. In particular, both the system power consumption and the source driver interface bandwidth requirement will be greatly reduced. These and other benefits are discussed, and the architecture of a TFT handset display system incorporating such an embedded framestore is described.
