摘要： Systems and methods for host-augmented touch-sensing are disclosed. The energy-efficiency of a touch sensitive device may be improved by dynamically adjusting the scanning sensitivity of the touch sensor based on host-augmented environmental information such as temperature, pressure, position, orientation, humidity, force, or battery charging mode.

摘要： Variable rate display interfaces are disclosed. In an exemplary aspect, a high-speed reverse data transfer is enabled over plural lanes of a display serial interface (DSI) bus during blanking periods. Further increases in bandwidth of each high-speed reverse data transfer may be achieved by increasing DSI clock speed during the blanking periods. Since a display relies on a host clock to send reverse data, the frequency of the reverse data is increased, which effectively increases the bandwidth of reverse channel lanes. By increasing the reverse bandwidth over existing pins in the DSI bus, more data may be transferred to the host, including raw touch/stylus data rather than processed data. The raw data may then be processed by the host's relatively powerful processors. By shifting the processing to the host, the need for a powerful touch screen controller (TSC) and/or a powerful touch display driver integrated circuit (TDDI) may be avoided.

摘要： Systems and methods for context-based touch-sensing and processing are disclosed. The energy-efficiency of a touch sensitive device may be improved by dynamically adjusting the function of the touch sensitive surface in real-time based on contextual information such as expected QoS, expected user input in defined regions-of-interest of the touch sensitive surface, and usage modalities of the touch sensitive device.

摘要： Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes.

摘要： A method, an apparatus, and a computer program product for processing touchscreen information are provided. The method may include receiving touchscreen data that includes node values representative of signals generated by a touchscreen panel, generating a first data frame including difference values, and transmitting the first data frame over a control data bus. Each of the difference values may be calculated as a difference between one of the node values and a different node-related value wherein the first data frame has a predefined size. The first data frame may be configured to permit a receiver of the first data frame to reconstruct the touchscreen data without information loss.
