Content presented on a display screen is updated responsive to a user input. Content is retrieved and segmented into bands that are rendered onto the display screen incrementally to provide a visual effect similar to an animation. A band is rendered at a starting location and after a refresh interval passes a subsequent band is rendered at a second starting location. The bands may be rendered until the content is shown on the display screen.

An electronic sensing device includes a display having a display surface and a plurality of micro light emitters configured to emit light for forming a display image on the display surface. A plurality of micro photodetectors is configured to detect light conditions at the display surface. A transceiver circuit is configured to drive the micro light emitters to emit light, drive the micro photodetectors to detect light and generate photo signals based on the detected light, coordinate the driving of the micro light emitters and of the micro photodetectors, and process the photo signals according to at least one of a list of sensing modes. The plurality of micro light emitters and the plurality of micro photodetectors are arranged on a surface of a display substrate.

In some examples, a pixel comprises a plurality of subpixels, wherein each subpixel includes a micro-motor, a rotatable substrate in which the micro-motor is embedded, and a plurality of micro-light emitting diodes (LEDs) embedded in the rotatable substrate.

A driving backplane, a display panel and a display device are disclosed. The driving backplane includes: a base substrate; a plurality of pixel driving circuits located on the base substrate; an electrode located on a side of each of the pixel driving circuits facing away from the base substrate and coupled with the pixel driving circuits; and a potential wire located between the electrode and the base substrate and coupled with the pixel driving circuits. Every at least two pixel driving circuits are coupled with a same signal line through a multiplexing controller, an orthographic projection of the controller on the base substrate completely falls into a range of a corresponding micro light emitting diode bonding region, and an orthographic projection of a control wire coupled with the controller on the base substrate completely falls into a range of an orthographic projection of the potential wire on the base substrate.

Provided is a method for driving an electronic paper display apparatus, including: applying a first driving signal to a first electrode of a microcapsule to be displayed in white, and applying a second driving signal to a first electrode of a microcapsule to be displayed in black according to a black-and-white particle image to be displayed. The first driving signal includes a first sub-driving signal applied in a display stage, wherein the first sub-driving signal is configured to drive the white particles in the microcapsule to be displayed in white to be closer to a display side relative to the black particles. The second driving signal includes a second sub-driving signal applied in the display stage, wherein the second sub-driving signal is configured to drive the black particles in the microcapsule to be displayed in black to be closer to the display side relative to the white particles.

A display device includes a non e-paper portion to display a first pattern element and a passive e-paper display portion to display a second pattern element juxtaposed relative to the first pattern element.

A wireless electronic label comprises a display module, a rectenna module and a control drive module. The display module has a display surface. The rectenna module is disposed on the display surface of the display module. The rectenna module is used to receive an electromagnetic wave signal and convert it into an electrical energy signal. The rectenna module is made of light-transmitting electronically conductive material. The control drive module is used to convert the electrical energy signal into electrical energy to power the wireless electronic label and to send a command signal to the display module. The display module is further used to display a label signal on the display surface according to the command signal.

In some examples, a pixel comprises a plurality of subpixels, wherein each subpixel includes a micro-motor, a rotatable substrate in which the micro-motor is embedded, and a plurality of micro-light emitting diodes (LEDs) embedded in the rotatable substrate.

A bodywork panel for a vehicle such as a racing car or a racing motorcycle is fitted with one or more optically clear panels, which are profiled to follow the aerodynamic form of the bodywork panel. A flexible reflective display screen, for examples based on e-paper, is mounted to an inner face of each optically clear panel such that an image on the display screen is visible outside the vehicle through the optically clear panel. A paint finish on the bodywork panel continues over a peripheral region of each optically clear panel, concealing a join between it and the bodywork panel. Images displayed on the display screens via a display controller can thus appear like painted graphics on the bodywork panel, except that they may be changed as desired. Thus, graphics on the vehicle, such as advertising and sponsorship logos, can be changed at will during a race. Leathers worn by racing motor cyclists can be fitted with similar display screens mounted behind optically clear flexible plastic panels sewn to the leathers.
