Abstract:
Abstract A display may have an array of organic light-emitting diode display pixels. Each display pixel may include a drive transistor coupled in series with one or more emission transistors and a respective organic light-emitting diode (OLED). A semiconducting-oxide transistor may be coupled between a drain terminal and a gate terminal of the drive transistor to help reduce leakage during low-refresh-rate display operations. To compensate for variations in the threshold voltage of the semiconducting-oxide transistor, the magnitude of a high voltage level of a scan control signal provided to the gate terminal of the semiconducting-oxide transistor may be adjusted. Sensing circuitry may be used to sense a display current while displaying a calibration image. The sensed display current may be compared to an expected display current associated with the calibration image. Processing circuitry may update the high voltage level based on the actual display current compared to the expected display current.

Abstract:
Gesichtspunkte der Gegenstandstechnik betreffen elektronische Vorrichtungen mit Anzeigen. Eine Anzeige kann ein Array von Anzeigepixeln und eine Steuerschaltung zum Betreiben der Anzeige einschließen. In einigen Szenarien können Interferenzsignale von anderen Komponenten der elektronischen Vorrichtung oder zusätzlichen externen Vorrichtungen mit der Steuerschaltung für die Anzeige gekoppelt sein und Verzerrungen in angezeigten Daten verursachen. Anzeigebilder können durch eine elektronische Vorrichtungsanzeige mit einer variierenden Phase angezeigt werden. Die variierenden Phasenanzeigebilder können jeweils ein Verzerrungsmuster einschließen, das aufgrund der variierenden Phase auch von Bild zu Bild variiert. Die variierenden Verzerrungsmuster können sich ausmitteln oder gegenseitig aufheben, wenn sie von einem Benutzer betrachtet werden, so dass kein sichtbares Artefakt des Interferenzsignals vom Benutzer gesehen wird. Die variierende Phase kann, falls gewünscht, aktiv auf das Interferenzsignal abgestimmt werden.
Abstract:
A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a plurality of touch node electrodes. In some examples, the touch sensor panel comprises a touch controller configured to drive and sense the plurality of touch node electrodes in a fully bootstrapped configuration to obtain a fully bootstrapped touch image, drive and sense the plurality of touch node electrodes in a second configuration, different from the fully bootstrapped configuration, to obtain a second touch image, the second touch image including an effect of water on the touch sensor panel, and determine a final touch image based on the fully bootstrapped touch image and the second touch image, the final touch image not including the effect of the water on the touch sensor panel. In some examples, the second configuration comprises a mutual capacitance configuration. In some examples, the second configuration comprises a partially bootstrapped configuration.
Abstract:
A self-capacitive touch sensor panel configured to have a portion of both the touch and display functionality integrated into a common layer is provided. The touch sensor panel includes a layer with circuit elements that can switchably operate as both touch circuitry and display circuitry such that during a touch mode of the device the circuit elements operate as touch circuitry and during a display mode of the device the circuit elements operate as display circuitry. The touch mode and display mode can be time multiplexed. By integrating the touch hardware and display hardware into common layers, savings in power, weight and thickness of the device can be realized.
Abstract:
A touch controller is disclosed. The touch controller can include sense circuitry configured to sense, during a self-capacitance portion of a touch frame, first one or more self-capacitances associated with a first plurality of touch pixels on a touch sensor panel, and sense, during a mutual capacitance portion of the touch frame, first one or more mutual capacitances associated with the first plurality of touch pixels. A touch processor can be configured to, based on the first one or more self-capacitances and the first one or more mutual capacitances, sense a single touch event associated with the touch frame.
