Publication number: 20150253890Abstract: Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.Type: ApplicationFiled: March 25, 2015Publication date: September 10, 2015Inventors: David A. Sobel, Sumant Ranganathan, Tianhao Li, John S. Walley, Glen Weaver, Kerrynn Jacques de Roche, Pi Sheng Chang

Publication number: 20150242021Abstract: Control circuitry for a touch panel includes a touch panel interface, a memory comprising touch positioning logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the touch positioning logic is executed, to perform selected processing of the touch panel, including scanning a touch panel and determining a touch panel blob resulting from a touch, obtaining blob characteristics of the touch panel blob, and determining a position of the blob relative to the touch panel based on the blob characteristics. The blob characteristics can be adjusted to more accurately position the blob in circumstances where the blob is located near the edge of the touch panel, is in close proximity to another blob, or when the touch panel has variation in the received signal noise.Type: ApplicationFiled: May 14, 2015Publication date: August 27, 2015Inventors: Glen Weaver, Sumant Ranganathan, Federicao Santiago Cattivelli, Tianhao Li, Bhupesh Kharwa, Satish Vithal Joshi, Kerrynn Jacques de Roche, Pi Sheng Chang

Publication number: 20130176273Abstract: A method for touch detection in a touch panel display includes entering a low power touch detection mode and intermittently stimulating the touch panel display with signals to determine if any touch event occurs without locating the touch event on the touch panel. If a touch event is detected, a full scan mode is entered to locate the touch event on the touch panel. This provides both faster touch detection and lower power operation for the touch panel display and controller circuit.Type: ApplicationFiled: March 8, 2012Publication date: July 11, 2013Applicant: Broadcom CorporationInventors: Tianhao Li, Sumant Ranganathan, David Amory Sobel, John S.

Publication number: 20130176270Abstract: Control circuitry for a touch panel includes a touch panel interface, a memory including object classification logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the object classification logic is executed, to perform selected processing of the touch panel heat map, including: classifying a touch as a hover touch, finger touch, or stylus touch; rejecting palm or other large object touches; rejecting knuckle touches; rejecting grip touches; and other processing.Type: ApplicationFiled: March 6, 2012Publication date: July 11, 2013Applicant: Broadcom CorporationInventors: Federico S.
