Avago Technologies has developed a new touch screen interface to enhance the operation and navigation of a wide range of portable electronic communications devices. This new touch screen technology is a mutual capacitance, multitouch controller that is capable of tracking up to four simultaneous touch points without the problem of ghost points that are found in many competing capacitive sensing technologies.
A touch screen system typically consists of an LCD or organic light-emitting diode (OLED) display, a touch sensitive panel, a protective cover lens, and a touch screen controller. Avago’s multitouch, capacitive touch screen controller has been specifically designed to offer highly accurate, responsive and fluid on-screen navigation to enhance the end-user’s experience. Other key features of the interface include 500 dpi resolution for jitter-free smooth tracking; hover rejection and palm detection to prevent false touch responses; good adjacent touch resolution for finer screen features and sensitivity; and 33 cm per second tracking speed.
Designed for ease of adoption and manufacturing, Avago’s touch screen interface does not require any touch sensitivity scaling, noise tuning or capacitive balancing. It also has a robust design that allows for flexible ASIC placement on flex or printed circuit boards. To simplify the assembly process, this device has a patent pending, built-in self test for panel indium tin oxide (ITO) breakage ‘open/shorts,’ which means no application test fixture is required. Panel integrity tests can also be run on devices in the field. Moreover, this touch screen controller offers configurable registers for customisation and debugging, and pairs with both glass and polyethylene terephthalate (PET) sensor panels. In addition to these key product features, a complete development kit, which includes software and sensor panel design guides, is provided to ease implementation.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
