Patent number: 11556205Abstract: Disclosed are sensing systems and methods that eliminate CPU intervention or interrupts when performing sensor scans of a touch interface, supports low power sensing operation without requiring periodic wake up of the CPU, and is scalable to multi-channel or multi-chip sensor configuration to support large touch screens or a high number of sensors. A sensor scanning module may operate in a chained-scan using direct memory access (CS-DMA) mode or an autonomous scan-multiple scan (AS-MS) mode to perform scanning of all sensors within a frame without requiring CPU intervention or generating CPU interrupts after every scan in the frame. The sensor scanning module may operate autonomously in a low-power always-on scan (LP-AOS) mode for multiple frames without CPU interaction until a touch event is detected. The CPU may operate in a low power sleep mode during the scan while providing consistent refresh rate and low touch-to-system wake up latency.Type: GrantFiled: August 3, 2021Date of Patent: January 17, 2023Assignee: Cypress Semiconductor CorporationInventors: Vibheesh Bharathan, Andrew Kinane

Patent number: 11531435Abstract: Technology directed to low-emissions touch controller in in-cell touch display systems is described. One in-cell touch controller includes a signal generator circuit that is configured to generate a sense signal according to a sensing function, the sense signal including a windowed sinusoidal waveform. The controller generates a transition signal to transition the in-cell touch display between a display function and the sensing function. The controller drives the sense signal and the transition signal on common voltage (VCOM) layer of electrodes during a touch scanning interval. During a display function interval an integrated display driver is configured to drive a first signal on the VCOM layer of electrodes during a display function interval.Type: GrantFiled: January 14, 2022Date of Patent: December 20, 2022Assignee: Cypress Semiconductor CorporationInventors: Viktor Kremin, Oleksandr Pirogov, Jens Weber, Yarsolav Lek, Daniel O'Keeffe, Brendan Lawton, Khosrov D Sadeghipour, Gaurav Panchanan, Andrew Kinane
