Abstract: A non-transitory computer-readable storage medium comprising instructions stored thereon. When executed by at least one processor, the instructions ban be configured to cause a computing device to, in response to an instruction to transition from a first refresh rate to a second refresh rate, modify a transitional frame. The modifying the transitional frame can include refreshing a first row in a display with a first adjustment to a peak signal of at least one pixel in the first row, and refreshing a second row in the display with a second adjustment to a peak signal of at least one pixel in the second row, the second row being refreshed after the second row, the second adjustment being greater than the first adjustment.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for driving a display including groups of light-emitting pixels. A sensor is arranged under the display. The sensor includes an emitter for directing electromagnetic radiation through multiple pixels of the display located over the emitter. The method includes addressing each group of pixels in the plurality of groups of light-emitting pixels with signals according to a frame rate wherein a period of each frame during which the groups of light-emitting pixels are addressed includes an emission-off period during which none of the multiple pixels located over the emitter emit light; and synchronizing emission of electromagnetic radiation from the emitter through the multiple pixels located over the emitter to occur only during the emission-off period of the multiple pixels located over the emitter.

Abstract: The present disclosure provides an electronic device utilizing a flexible display panel with multiple relief features formed in a periphery bending portion of the flexible display panel. The multiple relief features may facilitate lamination of the flexible display to a curved cover layer. The flexible display panel may have a circular shape utilized in a wearable device. An active area for displaying images may extend to the periphery bending portion of the flexible display panel, thus provided a wide viewing range for a user as well as enhancing an overall aesthetic appearance of the electronic device.

Abstract: Techniques and apparatuses are described that implement a trace design to reduce bezel area (106). An apparatus includes a pixel array (302) comprising pixel rows (112). The apparatus also includes a row line-driver (110-1) configured to provide electrical signals to at least two of the pixel rows (112-1, 112-2). The apparatus further comprises a plurality of electrical traces (202) that connect the row line-driver (110-1) to the pixel rows. At least one of the electrical traces (202) comprises a branch (210) such that a signal carried by the at least one of the electrical traces (202) enters the at least two of the pixel rows (112-1, 112-2). The branch is disposed closer to the pixel rows (112-1, 112-2) than the row line-driver (110-1). In this way, a number of the electrical traces (202) crossing a bezel area (106) is reduced compared to branching near the row line-driver (110-1).

Abstract: A display configuration to extend the light emitting and touch sensitive portion of a display panel into areas normally reserved for other light devices is disclosed. In the configuration, light devices and the display panel are configured to operate together. The display panel may include an aperture through the display panel to provide an unobstructed light path to a light device. The display panel may also include a routing area to provide space for data lines feeding pixels to be rerouted around the aperture. The routing area is partially obstructed by data lines but otherwise transparent. Accordingly, some display devices may be positioned behind the routing area and still operate.
