摘要： Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

摘要： 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.

摘要： A display device includes a first display area including a plurality of first pixel areas, a second display area including a plurality of second pixel areas and a plurality of transmission areas, a plurality of pixels arranged in a matrix form in the first and second display areas, and a first signal line and a second signal line disposed to correspond to each pixel column in the plurality of pixels. In each pixel column, one of the first and second signal lines may extend over the first and second display areas, and a remaining one of the first and second signal lines may not be disposed in the second display area.

摘要： An embodiment method of measuring ambient light comprises generating, by an ambient light sensor associated with a screen which alternates between first phases in which light is emitted and second phases in which no light is emitted by the screen, a first signal representative of an intensity of light received by the ambient light sensor during the first and second phases; comparing the first signal with a threshold intensity value; and controlling a timing of an ambient light measurement by the light sensor based on the comparison.

摘要： A device and method of an image processing system where a Field Sequential Color Delta Sigma Pulse Density Modulation is used for digital displays, where the digital displays are non-emissive. The device and method are a digital driving solution using Delta Sigma Encoding where N bit-per-component symbols at F1 frame-rate-per-second are represented using M bits-per-component symbols at F2 frame-rate-per-second, where N≥M and F2≥F1. The F2 frames are sent to a sequential color picker, which outputs frames with one color, followed by the next in a sequential pattern which reduces power consumption, increases color saturation, increases contrast, and increases brightness.

摘要： Aspects of the present disclosure relate to adjusting an illumination of a user depicted in one or more images when using a video conferencing application. In one example, one or more images depicting the user may be received from an image sensor. Further, an illumination of the user depicted in the one or more images may be determined to be unsatisfactory. For example, the user's face may be too bright or too dim. Accordingly, content displayed at a display device may identified and then modified. The modified content may then be rendered to a display device thereby changing the illumination of the user depicted in subsequent images. In examples, the modified content may include a graphical element, such as a ring of a specific color at least partially surrounding content rendered to and displayed at the display device.

摘要： The OLED voltage of a selected pixel is extracted from the pixel produced when the pixel is programmed so that the pixel current is a function of the OLED voltage. One method for extracting the OLED voltage is to first program the pixel in a way that the current is not a function of OLED voltage, and then in a way that the current is a function of OLED voltage. During the latter stage, the programming voltage is changed so that the pixel current is the same as the pixel current when the pixel was programmed in a way that the current was not a function of OLED voltage. The difference in the two programming voltages is then used to extract the OLED voltage.
