Abstract: An electronic device may have a display with an array of pixels. The device may have an array of components such as an array of light sensors for capturing fingerprints of a user through an array of corresponding transparent windows in the display. A capacitive touch sensor, proximity sensor, force sensor, or other sensor may be used by control circuitry in the device to monitor for the presence of a user's finger over the array of light sensors. In response, the control circuitry can direct the display to illuminate a subset of the pixels, thereby illuminating the user's finger and causing reflected light from the finger to illuminate the array of light sensors for a fingerprint capture operation. The display may have display driver circuitry that facilitates the momentary illumination of the subset of pixels with uniform flash data while image data is displayed in other portions of the display.

Abstract: A display may have an array of display pixels. Digital display data may be received by a digital-to-analog converter that converts the digital display data to analog display data. The magnitudes of the analog display data signals can be controlled by a regulated voltage received by the digital-to-analog converter. A brightness controller may have multiple peak luminance control (PLC) profiles. In accordance with an embodiment, a brightness setting may be processed by a lookup table to identify a pair of PLC profiles that is interpolated in order to obtain the desired regulated voltage. In accordance with another embodiment, a single PLC profile may be used that is a function of a combined parameter that takes into account both average frame luminance and the brightness setting. In accordance with yet another embodiment, a lookup table that specifies brightness setting offset values may be used to directly modulate the brightness setting.

Abstract: An electronic device includes processors that generate image data. The electronic device also includes an electronic display that displays the image data over a first frame duration by programming a first row of display pixels with the image data. The electronic display also displays the image data over the first frame duration by causing the first row of display pixels to emit light for an emission duration that is based at least in part on a first luminance of the image data. The electronic display further displays the image data over the first frame duration by resetting the first row of pixels at least two times before an end of the first frame duration.

Abstract: Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.

Abstract: A display device may include rows of pixels that display image data on a display and a circuit. The circuit may receive pixel data value of image data for a pixel in a first row of the rows of pixels, determine a weight factor to apply to the pixel data value based on a position of the first row with respect to the other rows, such that each row is associated with a current-resistance (IR) drop across the display. The weight factor is determined based on a respective IR drop associated with the first row. The circuit may also generate a weighted pixel data value based on the weight factor and the pixel data value and send the weighted pixel data value to a display driver circuit that renders the image data via the display.
