Image processing circuitry may include burn-in compensation circuitry that receives image data indicative of luminance outputs for display pixels of an electronic display and compensates the image data for burn-in related aging associated with the display pixels, generating compensated image data. Moreover, compensating the image data may include applying gains based on estimated amounts of aging associated with the display pixels and estimated amounts of current to be delivered to the display pixels. The image processing circuitry may also include burn-in statistics circuitry that tracks the estimated amounts of aging based on the compensated image data.

Micro-LED burn-in statistics and compensation systems and methods

An electronic device may include an electronic display having a pixel and that displays an image based on compensated image data. The electronic device may also include image processing circuitry communicatively coupled to the electronic display. The image processing circuitry may receive image data and determine a gain value for the pixel based on an aging value of the pixel that is based on previously displayed pixel values of the pixel. The image processing circuitry may also adjust the gain value based on a pixel value of the image data corresponding to the pixel to generate an updated gain value and adjust the pixel value of the image data based on the updated gain value to generate, at least in part, the compensated image data.

Inverse pixel burn-in compensation systems and methods

An electronic device may include an electronic display having display pixels that display an image based on compensated image data. The electronic display may also include pixel drive circuitry that provides power to the display pixels in accordance with the compensated image data. Additionally, the electronic device may include burn-in compensation circuitry communicatively coupled to the electronic display that receives input image data and generates the compensated input image data based on the input image data, a pixel aging history corresponding to the display pixels, and a driver aging history corresponding to the pixel drive circuitry.

Pixel drive circuitry burn-in compensation systems and methods

An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk, resistance of a laterally conductive OLED layer may be increased. The laterally conductive layer may include an organic host material, dopants, and a resistance-increasing additive. Another way to reduce leakage current is to apply bias voltages to the anodes of the display and/or expose the laterally conductive layer to ultraviolet light, causing dopants within the laterally conductive layer to degrade.

A display may include pixels (such as light-emitting diode pixels) that are susceptible aging effects (burn-in). To help avoid visible artifacts caused by burn-in during operation of the display, compensation circuitry may be used to compensate image data for the display. An optical sensor may be included behind the pixels to directly measure pixel brightness levels. The optical sensor may provide optical sensor data from testing operations to the compensation circuitry. The optical sensor may gather data during burn-in testing operations. During the burn-in testing operations, pixel groups including both high-usage pixels and low-usage pixels may sequentially emit light while the optical sensor gathers data. Brightness differences between the high-usage pixels and low-usage pixels may be used to characterize pixel aging in the display and compensate image data to mitigate visible artifacts caused by burn-in. The optical sensor may also gather data during global brightness testing operations.

Display with optical sensor for brightness compensation

The present invention relates to a holder for frozen food items and confections. The holder includes a grippable shaft having a first receptacle at a first end of the shaft and a second receptacle at a second end of the shaft. The first receptacle is adapted to receive a cone, such as those served with ice cream, or other frozen confection. The second receptacle is adapted to receive a stick, such as those served with frozen ice confections and ice cream bars. The receptacles are further adapted to receive drippage from melting frozen food items and confections. Furthermore, the holder is invertible to conveniently use either the first or second receptacle for receiving frozen food items supported in a cone, or on a stick. The receptacle not in use may be used as a support member to place the holder on a table or similar flat surface, if desired. The holder also includes a mounting cap that attaches to the holder for preparation and consumption of a frozen food item.
