TOUCH CONTROLLER ARCHITECTURE - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18335934 Titled 'TOUCH CONTROLLER ARCHITECTURE'

Simplified Explanation

The abstract describes a touch controller that can be programmed to configure touch circuitry based on a scan plan. The touch controller includes a transmit section to generate stimulation signals, a receive section to process touch signals, and a memory to store the touch signals. It also includes a programmable scan engine to configure the transmit section, receive section, and memory according to the scan plan. This touch controller offers more robust and flexible touch circuitry to handle different types of touch events on a touch panel. Additionally, an active stylus is mentioned, which can generate stimulation signals detectable by the touch controller during various touch events on the panel.

Original Abstract Submitted

A touch controller that can configure touch circuitry according to a scan plan, which can define a sequence of scan events to be performed on a touch panel is disclosed. The touch controller can include a configurable transmit section to generate stimulation signals to drive the panel, a configurable receive section to receive and process touch signals from the panel, and a configurable memory to store the touch signals. The touch controller can also include a programmable scan engine to configure the transmit section, the receive section, and the memory according to the scan plan. The touch controller advantageously provides more robust and flexible touch circuitry to handle various types of touch events at the panel. An active stylus that can generate stimulation signals that can be detected by the touch controller during various touch events at the panel is also disclosed.
