摘要： 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.

摘要： 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.
摘要翻译：非对称扫描逻辑通过比其他行更频繁地扫描触摸面板上的一些行来实现非对称面板扫描。注意，虽然可以驱动一次的整行，但是如果行中的特定像素是感兴趣的（例如，包括在用于聚焦的非对称扫描的任何感兴趣的区域中），则电路可以将其中的列的接收器断电存在像素以节省电力。非对称扫描逻辑有助于将注意力集中在触摸面板上的特定感兴趣区域，以补偿例如在感兴趣的区域中的高噪声或低信号强度。

摘要： 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.
摘要翻译：触摸面板显示器中的触摸检测的方法包括：输入低功率触摸检测模式，并用信号间歇地刺激触摸面板显示，以确定触摸事件是否发生，而不将触摸事件定位在触摸面板上。如果检测到触摸事件，则输入全扫描模式以在触摸面板上定位触摸事件。这为触摸屏显示器和控制器电路提供了更快的触摸检测和较低的功耗操作。

摘要： A method for a touch panel control circuit includes stimulating a touch panel and receiving signals responsive to the stimulating. Based on the received signals, water or another contaminant may be determined to be present on the touch panel. While the contaminant is present on the touch panel, a wet baseline mode of operation in which a different baseline value is used to detect a touch condition for the touch panel. When the contaminant is removed, operation returns to a dry baseline mode.

摘要： One method includes estimating, by a lost packet determination logic, an expected number of packets, expected to be received within a time interval, based on packet arrival speed; and determining a number of lost packets by using the expected number of packets and a packet counter wherein the packet counter counts a plurality of received packets. The method may further include comparing the expected number of packets to the packet counter and determining that the expected number of packets is greater than the packet counter; and then using the expected number of packets and the packet counter to determine the actual number of lost packets, where the actual number of lost packets exceeds the packet counter maximum. The methods may also introduce erasures when there is uncertainty of whether some packets or bytes are in error, such that a simplified erasure-based Reed-Solomon decoder may be used.
