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.

Abstract: Disclosed are techniques for removing dribble bits following the end-of-packet (EOP) of a High-Speed data packet inserted by the transmission envelope detector of a repeater/hub that interconnects electronic devices compliant with Universal Serial Bus (USB) Specification Revision 2.0 or higher. A physical layer logic (PHY) of a first port of the repeater/hub receives a High-Speed data packet to store a recovered bit stream into an elastic buffer. The recovered bit stream may include dribble bits inserted by the PHY after the EOP. The repeater/hub reads the recovered bit stream from the elastic buffer for transmission through the PHY of a second port. The repeater/hub monitors the EOP. When the EOP is detected, the repeater/hub prevents transmission of the dribble bits of the recovered bit stream following the EOP from the second port, eliminating the intended receiver of the High-Speed data packet from the complexity of dealing with dribble bits.

The second slope compensation starts at a maximum offset of the first slope compensation.

Abstract: 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.

Abstract: Disclosed are techniques for saving power in a Universal Serial Bus (USB) repeater/re-timer between a USB host and a peripheral device by intercepting packets received from the host to predict the direction of data traffic to selectively turn off/on circuitry of a peripheral port used to receive packets from the peripheral device. If a host port determines that the host is sending a start-of-frame (SOF) packet, the direction of data flow is from the host to the peripheral device, and the repeater may turn off the peripheral port such as squelch circuitry. If the host port determines that the host is sending a non-SOF packet, such as an address token that precedes a host-to-peripheral-device data transfer or a peripheral-device-to-host data transfer, the direction of data flow is anticipated to be from the peripheral device to the host, and the repeater may re-enable the deactivated circuitry of the peripheral port.
