The present disclosure provides a display panel, a method for driving the display panel, and a display device. The display panel includes a control unit including first and second processing circuits. A pixel circuit located within the fingerprint recognition region is connected to the first and second processing circuits of the corresponding control unit. In the fingerprint recognition mode, a pixel circuit located within the non-fingerprint recognition region receives a first light emission control signal, so that the light-emitting element does not emit light in first period and second sub-period and emits light in first sub-period. The second processing circuit provides a second light emission control signal, and a pixel circuit located within fingerprint recognition region responds to the second light emission control signal, so that the light-emitting element does not emit light in first period and emits light in first sub-period and second sub-period.

An LED screen for use in interactive golf driving ranges is disclosed. In an embodiment, a system includes a plurality of enclosures each housing LED nodes, where the plurality of enclosures is arranged in a plurality of rows to form an LED screen. The system also includes a coupler configured to couple a first one of the plurality of enclosures to a second one of the plurality of enclosures. The system also includes an LED processor configured to control each of the nodes via the coupler to display media on the LED screen.

Particular embodiments described herein provide for a wearable electronic device, such as a bracelet, watch, wristband or armband. One particular example implementation of a wearable electronic device may include a first display screen, a second display screen, and logic. At least a portion of the logic is implemented in hardware. The logic is configured to receive a communication over a wireless network, and to display, in the first display screen, a communication alert. The communication alert can be a graphic design. The logic is also configured to receive input data indicative of a screen transition input to view information associated with the communication, and to display, in the second display screen, the information associated with the communication. In further embodiments, the graphic design includes a notification pattern indicating one or more attributes of the communication. In further embodiments, the first and second display screens form a single display screen.

A head-mounted display (HMD) with a rolling illumination display panel can dynamically target a render time for a given frame based on eye tracking. Using this approach, re-projection adjustments are minimized at the location of the display(s) where the user is looking, which mitigates unwanted, re-projection-based visual artifacts in that region of interest. For example, logic of the HMD may predict a location on the display panel where a user will be looking during an illumination time period for a given frame, determine a time, within that illumination time period, at which an individual subset of the pixels that corresponds to the predicted location will be illuminated, predict a pose that the HMD will be in at the determined time, and send pose data indicative of this predicted pose to an application for rendering the frame.

A method and system for calibrating brightness variation in a display involve measuring brightness levels of light emitters in the display. The light emitters are divided into different groups based on the measured brightness levels. Each group is assigned a sub-frame duration. Groups with higher brightness are assigned shorter sub-frame durations than groups with lower brightness. Calibration information is stored for driving the light emitters such that during a frame period of the display, the light emitters are activated for durations corresponding to the sub-frame duration of their corresponding group.

An apparatus displays a plurality of lines representing a plurality of cracks occurring in a structure on a display unit, accepts an instruction to change a display state of the plurality of lines on the display unit, assigns order in which the display state is changed based on the instruction to each of a plurality of lines constituting one connecting point among the plurality of lines, and changes the display state of each of the plurality of lines constituting the one connecting point based on the order assigned by the assignment unit in response to acceptance of the instruction.

A display device, a door including the display device and a refrigerator including the door are provided. A display device includes: a frame configured to be rotatably mounted to a base object; a display panel mounted to the frame; a detector disposed in the frame, and configured to detect a movement of the frame and output a signal corresponding to the movement; and a controller configured to determine a movement state of the frame based on the signal, and control the display panel based on the movement state.

A method of displaying an image on a pixel array includes, at a pixel array having a plurality of pixels with subpixels, assigning one or more subpixels of a pixel as an image subpixel to display image data only and assigning one or the more of the subpixels as a symbology subpixel to display symbology data only. When data received at the pixel array includes image data the image data is display by the image subpixels only, and not by the symbology subpixels, to limit degrading in imagery displayed once the symbology subpixels exhibit burn-in. Image display systems and digital weapon sights are also described.

A display device, a door including the display device and a refrigerator including the door are provided. A display device includes: a frame configured to be rotatably mounted to a base object; a display panel mounted to the frame; a detector disposed in the frame, and configured to detect a movement of the frame and output a signal corresponding to the movement; and a controller configured to determine a movement state of the frame based on the signal, and control the display panel based on the movement state.

A device including at least a memory, a processor and an e-ink display, wherein the processor is configured and set up to read out service information from the memory, generate a machine-readable code based on the service information, and transmit the machine-readable code to the e-ink display such that the e-ink display displays the machine-readable code which, when read using a terminal, causes the terminal to retrieve the service information. A method of operating a device having an e-ink display.
