Abstract: Electronic devices, displays, and methods are provided for operating an electronic display in coexistence with sensors that could be adversely impacted by the operation of the electronic display. An electronic device may include an electronic display and a sensor. The electronic display may display image content by light emission during an emission period and periodically enter a quiet period in which the light emission of the electronic display is turned off. The sensor may perform sensing operations during the quiet period without interference from the operation of the electronic display.

Abstract: Circuits for programming a circuit with decreased programming time are provided. Such circuits include a storage device such as a capacitor for storing display information and for ensuring a driving device such as a driving transistor drives a light emitting device according to the display information. The present disclosure provides driving schemes for decreasing flickering perceived while displaying video content by introducing idle phases in between in emission phases to increase the effective refresh rate of a display. Driving schemes are also disclosed for reducing the effects of cross-talk by ensuring that programming information is refreshed in a display array that utilizes a driver connected to multiple data lines via a multiplexer.

Abstract: To reduce image artifacts induced by temperature variations associated with display pixels of an electronic display, processing circuitry may process temperature sensing data to obtain an average temperature and a temperature distribution of the electronic display. Based on the processed temperature data, the processing circuit may adjust a reference voltage applied to the display pixels to compensate for the average temperate. To further correct for the image artifacts, the processing circuitry may transform image data to luminance domain. Based on the processed temperature data, the processing may adjust luminance vales of the image data to compensate for the temperature distribution.

Current may be measured via a read transistor in each pixel.

Abstract: A display may be formed by an array of light-emitting diodes mounted to the surface of a display substrate. The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be configured to control one or more respective passive matrices. To control partial pixel cells in the display, a donor pixel control circuit in a partial pixel cell may control the pixels in a receptor partial pixel cell without a pixel control circuit. To mitigate the size of an inactive area of the display, fanout signal lines for the display may be formed in the light-emitting active area of the display. The fanout signal lines may be formed between a row of pixel control circuits and a bottom edge of the light-emitting active area.

The circuit under the high voltage ground domain may be located in an engineered high-voltage isolation well with a relatively large breakdown voltage.

Abstract: A voltage-programmed display system allows measurement of effects on pixels in a panel that includes both active pixels and reference pixels coupled to a supply line and a programming line. The reference pixels are controlled so that they are not subject to substantial changes due to aging and operating conditions over time. A readout circuit is coupled to the active pixels and the reference pixels for reading at least one of current, voltage or charge from the pixels when they are supplied with known input signals. The readout circuit is subject to changes due to aging and operating conditions over time, but the readout values from the reference pixels are used to adjust the readout values from the active pixels to compensate for the unwanted effects.

Such circuits include a storage device such as a capacitor for storing display information and for ensuring a driving device such as a driving transistor drives a light emitting device according to the display information. To increase programming time, the pixel circuits may be pre-charged or a biasing current may be applied to charge and/or discharge a data line and/or the driving device. Aspects of the present disclosure allow for the biasing current to drain partially through the storage device to allow the portion of the biasing current applied to the driving device to remain small while the data line discharges. Furthermore, the present disclosure provides display architectures and operation schemes for display arranged in segments each including a plurality of pixel circuits.
