Samsung releases touchscreen driven chip
SAMSUNG HAS DEVELOPED a chip that integrates a capacitive touchscreen control function in a mobile display driver package.
The chip is based on Samsung's Touch Embedded DDI technology and is part of a cunning plan to enable simplified, thinner designs.
In fact if you believe the company's press release there is no end to what the chip can do. It provides reduced chip area, lower power consumption and is much cheaper than existing technology. It will probably even do your dishes for you.
Samsung's vice president of the DDI development team, Samsung Electronics, Dr. Myunghee Lee, said that single-chip integration could make DDI technology a core component in advanced mobile platforms.
Capacitive touch screen control technology allows more advanced features such as soft and multi-touch functions. It also allows improved performance and durability.
No word yet on cost or when it might appear in a touchscreen phone near you. µ

this means the touch analysis is done in hardware and is therefore much faster then current devices while also using much less power (cpu offload with specialized hardware).
Doing all the touch input processing (velocity, acceleration, distance etc) by software run on the general purpose cpu is very inefficient, causing high load (power drain) and might even max out the cpu causing stuttering and lagging (unresponsiveness).
