Examples are disclosed that relate to mitigating unintended OLED display emissions arising from a proximity sensor emitter located behind an OLED display panel. One example provides a display device comprising an OLED display panel, a proximity sensor having a proximity sensor emitter positioned behind one or more OLED pixels of the OLED display panel with respect to a viewing surface of the OLED display panel, and a proximity emitter mask positioned between the proximity sensor emitter and the one or more OLED pixels to shield the one or more OLED pixels from the proximity sensor emitter.

High resolution displays, such as OLED displays, utilize complex driving circuits that can suffer from crosstalk. The crosstalk can affect the brightness of pixels in a row the display, which can be observed by a viewer as a crosstalk artifact. The severity of a crosstalk artifact may correspond to a contrast ratio of a high-contrast transition in which vertically adjacent pixels are sequentially driven by different driving signals during a scan. When a contrast ratio is above a maximum-perceptible contrast ratio, reducing the contrast ratio to the maximum-perceptible contrast ratio and can reduce, or eliminate, crosstalk artifacts. Disclosed herein are methods and devices that adjust pixels to reduce a crosstalk artifact without having a noticeable effect on contrast.

The method includes receiving, at a wrist-wearable device that is coupled with one or more sensors, video data and audio data associated with a video call between a user of the wrist-wearable device and at least one other user distinct from the user. The method further includes while causing presentation of the video data via a display of the wrist-wearable device and the audio data via a speaker that is in communication with the wrist-wearable device, determining whether sensed data from the one or more sensors indicates that a video-viewing precondition is present at the wrist-wearable device. If the video-viewing precondition is not present at the wrist-wearable device, the method includes continuing to cause presentation of the audio data and ceasing to cause presentation of the video data at the wrist-wearable device.

A fingerprint recognition system is disposed below a screen assembly of an electronic device and includes a light-emitting diode (LED), an image sensor, and a light shielding member. A light emitting surface of the LED faces the screen assembly and is configured to emit an optical signal. A photosensitive surface of the image sensor faces the screen assembly, where the optical signal received by the image sensor includes a fingerprint optical signal returned after being emitted by the LED to a finger, to generate a fingerprint image. The light shielding member is located between the LED and the image sensor, to block a part of signal light emitted by the LED.

A computer-implemented method for detecting vehicle crashes is presented. The method may include detecting, at a first mobile computing device a condition corresponding to a potential crash of a vehicle. The method may also include operating a beacon receive mode in response to detecting the potential crash condition, and receiving data from a second mobile computing device operating in a beacon transmit mode, the data indicating that the second mobile computing device detected an actual crash condition of the vehicle. The method may further include confirming, based on the potential crash condition and the data received from the second mobile computing device, that the potential crash is an actual crash.

To achieve multifunctionality, a large number of components and the time and effort for implementing the components are required, which leads to an increase in the manufacturing cost and a reduction in yield. A matrix display portion and a matrix optical sensor portion are formed over one substrate. In addition, a driver circuit of the display portion and a driver circuit of the optical sensor portion formed over the same substrate as that for the display portion are built in one chip, whereby the number of components can be reduced. When the optical sensor is formed in a display panel, a barcode reader function or a scanner function can be given to the display panel. Furthermore, a function of authenticating fingerprints or the like or an input/output function of a touch sensor can be given to the display panel.
