Patent number: 11868561Abstract: Apparatuses and methods of multi-phase scanning of a touch panel are described. One apparatus selects a sequence having a number of one values, negative one values, and zero values. The one values correspond to an in-phase drive signal, the negative one values correspond to an opposite-phase drive signal, and the zero values correspond to a reference signal (e.g., reference voltage or ground). A sum of the sequence is equal to zero. The apparatus applies one of the in-phase drive signal, the opposite-phase drive signal, or the reference signal to each of a first set of electrodes at a first stage according to the sequence. The apparatus rotates the sequence to obtain a rotated sequence and applies one of the signals according to the rotated sequence. The apparatus receives sense signals to detect a presence of an object on the touch panel.Type: GrantFiled: May 26, 2021Date of Patent: January 9, 2024Assignee: Cypress Semiconductor CorporationInventors: Volodymyr Bihday, Andriy Maharyta, Igor Kravets, Mykhaylo Krekhovetskyy, Ihor Musijchuk
