Abstract:
A method for operating an electronic display includes receiving, using a controller, sensor data related to operational parameters of the electronic display based at least in part on illuminating a sense pixel of at least one row of pixels of the electronic display, wherein a first set of pixels below the at least one row of pixels renders a portion of a first image frame and a second set of pixels above the at least one row of pixels renders a portion of a second image frame. The method also includes adjusting, using the controller, image display on the electronic display based at least in part on the sensor data.
Abstract:
A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.
Abstract:
An electronic device includes an electronic display, whereby the electronic display includes an active area that includes a pixel having a display behavior that varies with temperature. The electronic display also includes processing circuitry. The processing circuitry generates image data (106) to send to the pixel and adjust the image data to generate corrected image data (52) based at least in part on a stored correction value for the pixel (96), wherein the stored correction value corresponds to an effect of temperature on the pixel.
Abstract:
An electronic device includes an electronic display and processing circuitry. The electronic display includes pixels with behaviors that vary with temperature. As such, the processing circuitry generates image data to send to the electronic display (102) and adjust the image data (52) or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display (100). The processing circuitry determines the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.
Abstract:
Electronic devices, stored instructions, and methods for delaying operations that may increase a length of time used to charge a battery. The operations may include, for example, display off-time sensing that detect aging of a display while the display is off to set compensation values for operation of the display the next time the display is on. By delaying the operations until battery charging transitions into a reduced current consumption, the battery charging may occur more quickly that if such operations are performed during a higher current demand since reduced current availability may greatly increase a duration of time used to charge the battery in the higher current demand portion of the battery charging.
Abstract:
Electronic displays, systems, and methods that perform display panel sensing are provided. An electronic device may include processing circuitry that generates image data based at least in part on display panel sensing feedback and an electronic display. The electronic display may display the image data on pixels coupled to one of several sense lines. There may be an odd number of sense lines with common electrical characteristics. The electronic display may obtain display panel sense feedback at least in part by differentially sensing each one of the sense lines with sense lines with common electrical characteristics with another one of the sense lines the common electrical characteristics.
Abstract:
Electronic devices and methods pertain to reducing artifacts resulting from a thermal profile preexisting a boot up of an electronic device are disclosed. Scanning driving circuitry of the electronic device scans at least a portion of one or more pixels of an active area of a display using a boot up scan before a boot up sequence of at least a portion of an electronic device completes. The results of the boot up scan are stored in local buffers and transferred to one or more processors upon connection to the one or more processors. The results of the boot up scan cause the one or more processors to modify image data to reduce or eliminate artifacts that may result during boot up due to thermal profiles or other parameters that may cause artifacts.
Abstract:
Electronic devices and methods for compensating for noise in a display that includes sensing a current in a sensing channel of the display 18. Compensating for the noise also includes sensing an observation current from noise in an observation channel of the display and scaling the observation current to generate a scaled observation current. The scaled observation current is subtracted from the sense current to generate a compensated output. The compensated output is used to drive compensation operations of the display based at least in part on the compensated output to reduce effects of the noise.
