Abstract: This disclosure generally provides an input device that includes a reference voltage modulator that modulates reference voltage rails when performing capacitive sensing. In one embodiment, reference voltage rails are coupled to a DC power source which provides power to operate a panel that includes a display screen integrated with a touch sensing region. Before performing capacitive sensing, the input device may isolate the DC power source from the reference voltage rails and use the reference voltage rails to modulate the rails—e.g., VDD and VGND. The input device may include a receiver that simultaneously acquires resulting signals from a plurality of display and/or sensor electrodes when modulating the reference voltage rails. The resulting signals can then be processed to determine if an input object is interacting with the input device.

Abstract: This disclosure generally provides a fingerprint sensor that derives a fingerprint by measuring capacitive sensing signals while modulating a reference voltage rail used to power the fingerprint sensor. In one embodiment, the fingerprint sensor is integrated into an electronic device which may include other components such as a display, I/O devices, speakers, and the like. To power these components, the electronic device may include a DC power supply which outputs reference voltages. When transmitting the reference voltages to the fingerprint sensor, the electronic device may modulate the voltages using a modulating signal. Because the reference voltages are used to power the components in the fingerprint sensor, modulating the rail voltages also causes the components coupled to the reference voltages to also modulate. While this modulation occurs, the fingerprint sensor measures resulting signals using a plurality of sensor electrodes which are then processed to derive a fingerprint.

Abstract: Embodiments of the invention generally provide a display panel that uses predefined criteria to determine when to send a request for a display frame to a display source. The predefined criteria may be, for example, when the display panel needs to refresh the display faster than the display source transmits display frames, when the display source fails to send a new display frame within a specified time period, when a maximum refresh time is exceeded and the displayed image begins to decay or leak, and the like. Furthermore, the display panel may include a frame buffer for storing the display frames received from the display source. Additional predefined criteria may be when the display frame stored in the frame buffer becomes corrupted or when the frame buffer lacks enough available memory to store the frame. In response, the display panel may request the display source retransmit the previous display frame.

Abstract: Display devices with improved routing between connectors and source drivers disposed on a substrate such as glass. Various features improve different characteristics of the routings between the connectors and source drivers. For example, a t-shaped connector is provided to ensure voltage provided to the source drivers is approximately equal. Routings may be tapered (i.e., altered in width) to reduce the amount of area consumption in locations where doing so is desirable but to decrease resistance in areas having more space. Routings may also include stacked power supply and ground traces to provide benefits such as improved decoupling capacitance. Other features are provided.

Abstract: Various embodiments enable driving one or more sub-pixels with a source voltage while concurrently modulating the voltage of one or more common electrodes coupled to the sub-pixels to perform input sensing with the common electrodes. The voltage driven onto the sub-pixel may be shifted while the common electrode is modulated by a value about equal to about the amplitude of the modulation applied to the common electrode. Thus, the potential difference between the source line and common electrode remains substantially unchanged so that display asperities are not introduced while input sensing while concurrently updating a sub-pixel with display information. Thus, the common electrode(s) may be modulated for input sensing without interfering with display updating of the one or more sub-pixels, greatly increasing the amount of time available for performing input sensing and/or display updating.
Abstract translation: 各种实施例使得能够以源电压驱动一个或多个子像素，同时同时调制耦合到子像素的一个或多个公共电极的电压，以对公共电极执行输入感测。 驱动到子像素上的电压可以移动，同时公共电极被调制大约等于施加到公共电极的调制的幅度的值。 因此，源极线和公共电极之间的电位差基本上保持不变，使得在同时更新具有显示信息的子像素的同时，在输入感测期间不引入显示粗糙度。 因此，可以调制公共电极用于输入感测，而不干扰一个或多个子像素的显示更新，从而大大增加了可用于执行输入感测和/或显示更新的时间量。
